Description

Iron removal device, slurry preparation system and metal impurity removal method Technical Field

[0001] The present application relates to the technical field of automation equipment, and in particular to an iron removal device, a slurry preparation system, and a method for removing metal impurities. Background Art

[0002] In the battery production process, slurry is typically prepared, and then used to form the battery electrodes and other components. After the slurry is prepared, it is generally necessary to remove metallic impurities such as iron to improve the purity and quality of the slurry.

[0003] In some cases, metallic impurities in the slurry are removed by the magnetic attraction of a magnetic bar. After prolonged operation, the magnetic bar needs to be regularly replaced or manually cleaned, resulting in a low degree of automation for the iron removal device used to remove metallic impurities in the slurry, and in turn, low operating efficiency. Technical issues

[0004] In view of the above problems, the purpose of the embodiments of the present application is to provide an iron removal device, a slurry preparation system and a metal impurity removal method, which can improve the technical problems of low automation and low work efficiency. Technical Solutions

[0005] The technical solution adopted in the embodiment of this application is:

[0006] In a first aspect, an embodiment of the present application provides an iron removal device, comprising:

[0007] The cleaning mechanism comprises a deironing chamber and a cleaning chamber, wherein the deironing chamber is used for allowing the slurry to pass through;

[0008] The iron removal mechanism includes a magnetic attraction member that can alternately move into the iron removal chamber and the cleaning chamber. The magnetic attraction member can magnetically attract metal impurities in the slurry in the iron removal chamber and can also perform cleaning in the cleaning chamber.

[0009] By adopting the above technical solution, the magnetic element can be moved alternately into the iron removal chamber and the cleaning chamber. In this way, when working, the magnetic element can be moved into the iron removal chamber first, so that the magnetic element can magnetically attract the metal impurities in the slurry in the iron removal chamber, and then the magnetic element can be moved from the iron removal chamber to the cleaning chamber, so that the magnetic element can be cleaned in the cleaning chamber to remove the metal impurities on the magnetic element. In this way, the magnetic element can alternately attract metal impurities and clean the magnetic element without having to replace the magnetic element after it has attracted a lot of metal impurities, which reduces the replacement of the magnetic element and does not require excessive manual intervention, thereby making the iron removal device have higher automation performance, thereby improving the working efficiency of the iron removal device.

[0010] In some embodiments, the cleaning mechanism further includes a scraper configured to scrape metal impurities on the magnetic element into the cleaning chamber.

[0011] By adopting the above technical solution, the scraper can clean the magnetic element, making the cleaning of the magnetic element very simple and easy to implement. This helps to improve the cleaning efficiency of the magnetic element, thereby improving the cleaning efficiency and production capacity of the slurry.

[0012] In some embodiments, the scraper includes multiple scraping parts; the multiple scraping parts can move toward each other to embrace the magnetic part; the magnetic part can move in and out of the cleaning chamber to allow the scraping parts to scrape off metal impurities when moving out of the cleaning chamber; the multiple scraping parts can also move in opposite directions.

[0013] By adopting the above technical solution, when multiple scraping parts hold the magnetic part and the magnetic part moves out of the cleaning chamber, the multiple scraping parts can completely contact and hold the position of the magnetic part with metal impurities, so that all the metal impurities on the magnetic part can be scraped off as much as possible, thus reducing the cleaning blind spot of the magnetic part and improving the cleaning effect of the magnetic part. In addition, the assembly requirements and motion control requirements for the scraping parts are relatively low, and there is no need to have excessive requirements for the precise movement of the multiple scraping parts in the direction of movement and the direction of movement. After the magnetic part is extended into the cleaning chamber, it is only necessary to control the multiple scraping parts to move in the direction of movement until they hold the magnetic part. After the magnetic part is moved out of the cleaning chamber, it is only necessary to control the multiple scraping parts to move in the direction of movement to the approximate position. This makes the maintenance of the scraping parts very convenient and the production cost is low.

[0014] In some embodiments, the plurality of scraping portions define a through groove for holding the magnetic element, and a protruding structure is provided on the inner circumference of the through groove, and the scraping portions support the magnetic element through the protruding structure.

[0015] By adopting the above technical solution, by setting a protruding structure on the inner peripheral side of the through groove, the friction between the scraper and the magnetic part can be increased, thereby increasing the force of the scraper to scrape off metal impurities on the surface of the magnetic part, thereby improving the cleaning effect of the magnetic part.

[0016] In some embodiments, the protruding structure is a microstructure provided on the scraping portion, or the protruding structure is a buffer structure.

[0017] By adopting the above technical solution, by providing a microstructure or a buffer structure on the scraping part, the friction between the scraping part and the magnetic part can be effectively increased, so that the scraping part has a higher cleaning effect on the magnetic part.

[0018] In some embodiments, the cleaning mechanism further comprises a first driving structure for driving the plurality of scraping parts to move toward each other or away from each other.

[0019] By adopting the above technical solution, the iron removal device can automatically clean the magnetic attraction parts, thereby improving the cleaning efficiency of the magnetic attraction parts and further improving the working efficiency of the iron removal device.

[0020] In some embodiments, the first driving structure includes a first driver and a driving seat; the driving seat is provided with multiple sliding grooves, and the multiple scraping parts can slide along the multiple sliding grooves accordingly to move toward each other or move away from each other; the first driver is used to drive the driving seat to move so that the scraping parts slide along the sliding grooves.

[0021] By adopting the above technical solution, on the one hand, the iron removal device can automatically clean the magnetic element, thereby improving the working efficiency of the iron removal device. On the other hand, it can enable the multiple scraping parts to flexibly move toward or away from each other, thereby improving the working flexibility of the iron removal device.

[0022] In some embodiments, the iron removal device further includes a sewage pipe connected to the cleaning chamber, and the sewage pipe is used to discharge metal impurities in the cleaning chamber.

[0023] By adopting the above technical solution, when the clean chamber contains a large amount of metal impurities, the metal impurities in the clean chamber can be discharged through the sewage pipe. In this way, the clean chamber can have a larger space to accommodate metal impurities, and the clean chamber can be reused repeatedly. Moreover, by discharging the metal impurities in the clean chamber through the sewage pipe, the clean chamber is cleaned, and the clean chamber can be reused repeatedly without excessive human intervention in the cleaning work of the clean chamber. This also improves the automation performance of the iron removal device, saves time and labor, and also improves the working efficiency of the iron removal device.

[0024] In some embodiments, the inner cavity of the iron removal chamber is cylindrical, the magnetic element is shaft-shaped, and the difference between the inner diameter of the iron removal chamber and the diameter of the magnetic element is less than 50 mm.

[0025] By adopting the above technical solution, on the basis that the inner cavity of the iron removal chamber can accommodate the slurry and the magnetic attraction component at the same time, the slurry in the iron removal chamber will not be too much, so that the magnetic attraction component can fully contact the slurry to fully magnetically attract the metal impurities in the slurry, thereby effectively improving the cleaning effect of the magnetic attraction component 21 on the slurry.

[0026] In some embodiments, the iron removal chamber has a first feed port, which is located at the end of the iron removal chamber along the direction in which the magnetic element enters and exits the iron removal chamber, and the first feed port can allow slurry to enter.

[0027] By adopting the above technical solution, when the magnetic attraction element is extended into the iron removal chamber, when the slurry flows in the iron removal chamber in a direction parallel to the direction in which the magnetic attraction element enters and exits the iron removal chamber, the slurry can better flow to the end of the magnetic attraction element entering the iron removal chamber along the direction Y, and flow to the outer peripheral surface of the magnetic attraction element around the first axis. This can reduce the magnetic blind area of ​​the magnetic attraction element and improve the magnetic attraction efficiency of metal impurities.

[0028] In some embodiments, the iron removal chamber also has a second feed port, and the first feed port and the second feed port are respectively arranged at the two ends of the iron removal chamber along the direction in which the magnetic suction part enters and exits the iron removal chamber, and any one of the first feed port and the second feed port is used for slurry to enter, and the other is used for slurry to flow out.

[0029] By adopting the above technical solution, on the one hand, the flow direction of the slurry in the iron removal chamber can be made roughly parallel to the distribution direction of the first and second feeding ports, thereby reducing the adsorption blind area of ​​the magnetic attraction component. On the other hand, it facilitates the connection and assembly operation between the device for outputting and inputting slurry and the iron removal chamber.

[0030] In some embodiments, the iron removal chamber has a first opening for the magnetic element to enter and exit; the magnetic element includes a magnetic body for magnetically attracting metal impurities and a sealing member provided on the magnetic body, and the sealing member is used to seal the first opening when the magnetic body enters the iron removal chamber.

[0031] By adopting the above technical solution, when the magnetic element is extended into the iron removal chamber, the sealing element of the magnetic element seals the first opening of the iron removal chamber, which can improve the problem of slurry in the iron removal chamber overflowing from the first opening.

[0032] In some embodiments, the seal and / or the magnetic body is provided with a first lock buckle, and the iron removal chamber is provided with a second lock buckle; the first lock buckle can be locked with the second lock buckle to restrict the magnetic body from moving out of the iron removal chamber; the first lock buckle can also be unlocked with the second lock buckle to allow the magnetic body to move out of the iron removal chamber.

[0033] By adopting the above technical solution, when the magnetic element is inserted into the iron removal chamber, the first lock on the magnetic element can be locked with the second lock on the iron removal chamber, thereby limiting the magnetic element from moving out of the iron removal chamber and limiting the seal from opening the first opening. In this way, the state in which the magnetic element is inserted into the iron removal chamber can be better maintained to maintain the magnetic attraction of metal impurities by the magnetic element in the iron removal chamber. In addition, the sealing state of the seal on the first opening can be maintained, thereby improving the problem of the seal opening the first opening under the pressure of the slurry, causing the slurry to overflow.

[0034] In some embodiments, the second lock buckle is provided with a lock slot, and the magnetic body can rotate around the first rotation axis so that the first lock buckle can be rotated in and limited in the lock slot or rotated out of the lock slot along the first direction; the first direction is parallel to the direction of the magnetic body entering and exiting the iron removal chamber, and is parallel to the first rotation axis.

[0035] By adopting the above technical solution, the structures of the first lock buckle and the second lock buckle are very simple and easy to manufacture. In addition, by driving the magnetic attraction body to rotate about the first rotation axis, the first lock buckle and the second lock buckle can be locked or unlocked. This makes the operation of switching the first lock buckle and the second lock buckle between the locked state and the unlocked state very simple, convenient and easy to implement.

[0036] In some embodiments, the iron removal mechanism further includes a second driving structure, which is used to drive the magnetic body to move, so as to drive the first lock to lock or unlock relative to the second lock.

[0037] By adopting the above technical solution, the second driving structure is used to drive the locking or unlocking between the first lock buckle and the second lock buckle, which can improve the automation level of the iron removal device and further improve the working efficiency of the iron removal device.

[0038] In some embodiments, the iron removal chamber has a first opening for the magnetic attraction member to enter and exit, and the cleaning chamber has a second opening for the magnetic attraction member to enter and exit;

[0039] The iron removal mechanism also includes a third drive structure, and the iron removal device also includes a fourth drive structure; the third drive structure is used to drive the magnetic element to move, so as to drive the magnetic element to move between one side of the first opening and one side of the second opening; the fourth drive structure is used to drive the magnetic element in and out of the iron removal chamber or in and out of the cleaning chamber.

[0040] By adopting the above-mentioned technical solution, the third drive structure and the fourth drive structure can alternately drive the magnetic attraction part to move, thereby realizing the effect of the magnetic attraction part moving between the iron removal chamber and the cleaning chamber, and can make the movement of the magnetic attraction part more automated, that is, improve the automation performance of the iron removal device, which helps to improve the working efficiency of the iron removal device.

[0041] In some embodiments, the iron removal device further includes a receiving tray, which can be located on both sides of the first opening and the second opening to receive the slurry and / or metal impurities flowing out of the magnetic element.

[0042] By adopting the above technical solution, the receiving plate can receive the slurry and / or metal impurities on the magnetic element when the magnetic element is moved out of the iron removal chamber and the cleaning chamber. This can improve the problem of the slurry and / or metal impurities on the magnetic element being thrown out of the iron removal device, thereby maintaining the cleanliness of the iron removal device during operation.

[0043] In some embodiments, the receiving tray can move between a first position and a second position; when the receiving tray is in the first position, it is used to receive slurry and / or metal impurities, and when the receiving tray is in the second position, it can allow the magnetic suction component to enter and exit the iron removal chamber or the cleaning chamber.

[0044] By adopting the above technical solution, the slurry or metal impurities flowing out of the magnetic element can be better received during the movement of the magnetic element, and the problem of interference of the receiving tray with the movement of the magnetic element can also be improved.

[0045] In some embodiments, the cleaning mechanism includes multiple iron removal chambers and multiple cleaning chambers, and the iron removal chambers and the cleaning chambers are alternately distributed along the circumferential direction; the iron removal mechanism includes multiple magnetic parts, and each magnetic part can rotate around the second rotation axis to alternately rotate to the side of the corresponding iron removal chamber along the first direction and the side of the corresponding cleaning chamber along the first direction; the magnetic parts can enter and exit the iron removal chamber or enter and exit the cleaning chamber along the first direction, and the second rotation axis is parallel to the first direction.

[0046] By adopting the above technical solution, multiple cleaning chambers, multiple iron removal chambers and multiple magnetic suction parts are set up, so that the iron removal device can complete the removal of metal impurities in the slurry in multiple iron removal chambers at one time, and can also complete the cleaning work of multiple magnetic suction parts at one time, thereby improving the working efficiency of the iron removal device.

[0047] In some embodiments, the iron removal chamber has a first feed port and a second feed port, either one of the first feed port and the second feed port is used for allowing the slurry to enter, and the other is used for allowing the slurry to flow out; the cleaning mechanism also includes a first confluence pipe and a second confluence pipe, and the first feed ports of multiple iron removal chambers are connected to the first confluence pipe, and the second feed ports of multiple iron removal chambers are connected to the second confluence pipe.

[0048] By adopting the above technical solution, the slurry in multiple iron removal chambers can be converged through the first confluence pipe and the second confluence pipe, without the need for each iron removal chamber to be connected to an external device for inputting and outputting slurry through its own pipe. This simplifies the pipe design for the slurry circulation in the iron removal chamber, and further simplifies the iron removal device.

[0049] In some embodiments, the first conduit is annular and is disposed outside the iron removal chamber and the cleaning chamber.

[0050] By adopting the above technical solution, the first confluence pipe is arranged in a ring outside multiple cleaning chambers and multiple iron removal chambers, so that the first confluence pipe, the second confluence pipe, the cleaning chamber, the iron removal chamber, etc. can be made more compact, thereby improving the structural compactness of the iron removal device and realizing the miniaturized design of the iron removal device.

[0051] In some embodiments, the iron removal device further includes a pressure relief pipe connected to the iron removal chamber, and the pressure relief pipe is used for pressure relief.

[0052] By adopting the above technical solution, the pressure relief pipe can achieve a pressure relief effect on the iron removal chamber. This can minimize the pressure difference between the iron removal chamber and the external environment, facilitating the flexible flow of slurry within the iron removal chamber, thereby facilitating the magnetic attraction of the metal impurities in the slurry within the iron removal chamber. Based on this, the problem of excessive pressure in the iron removal chamber causing difficulty in the flow of slurry, which in turn prevents the magnetic attraction from successfully attracting metal impurities, can be alleviated.

[0053] In some embodiments, there are multiple cleaning mechanisms, and the iron removal chambers of the multiple cleaning mechanisms are connected in sequence.

[0054] By adopting the above technical solution, the slurry can be passed into the iron removal chambers of multiple cleaning mechanisms in sequence, so as to remove metal impurities through the magnetic suction parts in sequence, thereby improving the metal impurity removal effect of the slurry.

[0055] In a second aspect, an embodiment of the present application provides a slurry production system, including an iron removal device.

[0056] By adopting the above technical solution and the iron removal device according to the above embodiments, the iron removal device also has high automation performance, thereby improving the working efficiency of the iron removal device. Accordingly, the slurry production system has high automation performance and high working efficiency.

[0057] In a third aspect, an embodiment of the present application provides a method for removing metal impurities, which is applied to an iron removal device and includes the following steps:

[0058] Drive the magnetic attraction element into the iron removal chamber and introduce slurry into the iron removal chamber;

[0059] The magnetic element is driven from the iron removal chamber into the cleaning chamber to clean the magnetic element.

[0060] By adopting the above technical solution, since the metal impurity removal method is applied to the iron removal device involved in the above embodiments, the metal impurity removal method can have higher automation performance and work efficiency.

[0061] In some embodiments, after driving the magnetic element from the iron removal chamber to the cleaning chamber to clean the magnetic element, the method further includes:

[0062] The magnetic element is removed from the cleaning chamber, and the metal impurities on the magnetic element are scraped off into the cleaning chamber by a scraping element.

[0063] The scraper can effectively clean the magnetic element by scraping metal impurities off the magnetic element and into the cleaning chamber, making the cleaning of the magnetic element very simple and easy to implement. This helps to improve the cleaning efficiency of the magnetic element, thereby improving the cleaning efficiency and production capacity of the slurry.

Modes for Carrying Out the Invention

[0090] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0091] In the description of this application, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0092] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0093] In the description of this application, "a plurality of" means more than two, and unless otherwise specifically defined, "more than two" includes two. Accordingly, "a plurality of groups" means more than two groups, including two groups.

[0094] In the description of this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0095] In the description of this application, the term "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists, A and B exist at the same time, and B exists. In addition, in this application, the character " / " generally indicates that the related objects are in an "or" relationship.

[0096] In the battery production process, slurry is typically prepared, and then used to form the battery electrodes and other components. After the slurry is prepared, it is generally necessary to remove metallic impurities such as iron to improve the purity and quality of the slurry.

[0097] In some cases, metallic impurities in slurry are removed through the magnetic attraction of a magnetic bar. After prolonged operation, these bars require regular replacement or manual cleaning. Consequently, the removal of metallic impurities from slurry requires significant manual intervention, resulting in a low degree of automation for the iron removal equipment used to remove metallic impurities from slurry, and consequently, inefficient removal of metallic impurities from slurry.

[0098] Based on the above considerations, the first aspect of the embodiment of the present application provides an iron removal device, which can be moved into the iron removal chamber or the cleaning chamber through a magnetic element. In this way, when working, the magnetic element can be first moved into the iron removal chamber to allow the magnetic element to magnetically attract metal impurities in the slurry in the iron removal chamber, and then the magnetic element can be moved from the iron removal chamber to the cleaning chamber to allow the magnetic element to be cleaned in the cleaning chamber to remove the metal impurities on the magnetic element. In this way, the magnetic element can alternately attract metal impurities and clean the magnetic element without having to replace the magnetic element after it has attracted more metal impurities, which reduces the replacement of the magnetic element and does not require excessive manual intervention, thereby making the iron removal device have higher automation performance and thus improving the working efficiency of the iron removal device.

[0099] It is understandable that the iron removal device provided in the embodiment of the present application is mainly used for but not limited to iron removal, that is, the iron removal device can be used to remove iron in the slurry as well as other metal impurities in the slurry. Among them, the slurry can be a slurry for making pole pieces, and of course it can also be a slurry for forming other components of the battery, or even a slurry in other fields. In other words, the iron removal device provided in the embodiment of the present application can be applied to the field of battery production, and of course it can also be applied to other fields besides the battery field.

[0100] Please refer to Figures 1 to 4 together. Figure 1 shows a schematic diagram of the iron removal device 100 provided in an embodiment of the present application, Figure 2 shows a schematic diagram of the coordination of the cleaning mechanism 10 and the iron removal mechanism 20, Figure 3 shows a top view of the cleaning mechanism 10, and Figure 4 shows a front view of the cleaning mechanism 10. The iron removal device 100 provided in an embodiment of the present application includes a cleaning mechanism 10 and an iron removal mechanism 20. The cleaning mechanism 10 includes an iron removal chamber 11 and a cleaning chamber 12, and the iron removal chamber 11 is used for slurry to pass through. The iron removal mechanism 20 includes a magnetic member 21, and the magnetic member 21 can move alternately into the iron removal chamber 11 and the cleaning chamber 12. The magnetic member 21 can magnetically attract metal impurities in the slurry in the iron removal chamber 11, and the magnetic member 21 can also be cleaned in the cleaning chamber 12.

[0101] As shown in FIG. 2 and FIG. 4 , both the iron removal chamber 11 and the cleaning chamber 12 are solid structures having inner cavities.

[0102] The magnetic component 21 can move between the iron removal chamber 11 and the cleaning chamber 12, so as to move alternately to the iron removal chamber 11 and the cleaning chamber 12. Specifically, the magnetic component 21 can be moved out of the inner cavity of the cleaning chamber 12 and extend into the inner cavity of the iron removal chamber 11. The magnetic component 21 can also be moved out of the inner cavity of the iron removal chamber 11 and extend into the inner cavity of the cleaning chamber 12. It can be understood that the magnetic component 21 can enter and exit the inner cavity of the iron removal chamber 11, and can also enter and exit the inner cavity of the cleaning chamber 12. Among them, as shown in Figures 2 and 4, the direction in which the magnetic component 21 enters and exits the iron removal chamber 11 is the direction Y shown in the figure, and the direction in which the magnetic component 21 enters and exits the cleaning chamber 12 is also the direction Y shown in the figure.

[0103] As shown in Figures 2 and 3, the iron removal chamber 11 has a first opening 1101, which is connected to the inner cavity of the iron removal chamber 11, and the magnetic member 21 can enter and exit the inner cavity of the iron removal chamber 11 through the first opening 1101. The cleaning chamber 12 has a second opening 1201, which is connected to the inner cavity of the cleaning chamber 12, and the magnetic member 21 can enter and exit the inner cavity of the cleaning chamber 12 through the second opening 1201.

[0104] The magnetic element 21 is a component that can magnetically attract metal. If the slurry in the iron removal chamber 11 is mixed with metal impurities, when the magnetic element 21 is inserted into the inner cavity of the iron removal chamber 11, the magnetic element 21 can magnetically attract the metal impurities in the slurry, thereby removing the metal impurities from the slurry, that is, achieving a cleaning effect on the slurry.

[0105] The structure of the magnetic element 21 can be various. In some implementations, as shown in Figures 2 and 4, the magnetic element 21 is a long strip structure. Specifically, the magnetic element 21 is arranged to extend in the direction of entering and exiting the iron removal chamber 11. In this way, the magnetic element 21 can extend into the inner cavity of the iron removal chamber 11 to a greater extent, thereby contacting more slurry, so that the metal impurities in the slurry can be magnetically attracted to a greater extent, so as to have a better cleaning effect on the slurry. For example, as shown in Figures 2 and 4, the magnetic element 21 is a magnetic rod. The cross-section of the magnetic element 21 is circular, and can also be elliptical, triangular, and other shapes. Among them, the cross-section of the magnetic element 21 is a cross-section of the magnetic element 21 that is perpendicular to its own length direction (extension direction). At this time, the length direction (extension direction) of the magnetic element 21 is parallel to the direction of entering and exiting the iron removal chamber 11. Among them, the length direction (extension direction) of the magnetic element 21 is the direction Y shown in the figure. Of course, in other implementations, the magnetic member 21 may also be in other shapes besides a long strip.

[0106] The iron removal chamber 11 is used for allowing slurry to pass through, specifically, the slurry can pass into the iron removal chamber 11 and can also flow out of the iron removal chamber 11. There are many ways for the slurry to enter and exit the iron removal chamber 11. In some implementations, as shown in Figures 2 and 4, the iron removal chamber 11 has a first feed port 1102 and a second feed port 1103, and the first feed port 1102 and the second feed port 1103 are both connected to the inner cavity of the iron removal chamber 11, and the first feed port 1102 and the second feed port 1103 are spaced apart from the first opening 1101. The first feed port 1102 is the inlet of the slurry, and the second feed port 1103 is the outlet of the slurry; or, the first feed port 1102 is the outlet of the slurry, and the second feed port 1103 is the outlet of the slurry. During operation, the slurry can enter the inner cavity of the iron removal chamber 11 through any one of the first feed port 1102 and the second feed port 1103, and flow out of the iron removal chamber 11 through the other of the first feed port 1102 and the second feed port 1103. Among them, the first feed port 1102 and the second feed port 1103 can be different openings. Of course, the first feed port 1102 and the second feed port 1103 can also be the same opening. In other implementations, the iron removal chamber 11 may be provided with the above-mentioned first feed port 1102, but not the above-mentioned second feed port 1103. At this time, the first feed port 1102 is the inlet of the slurry, and the first opening 1101 of the iron removal chamber 11 is the outlet of the slurry; or, the first feed port 1102 is the outlet of the slurry, and the first opening 1101 of the iron removal chamber 11 is the inlet of the slurry. In some other implementations, the iron removal chamber 11 is not provided with the above-mentioned first feed port 1102 and the above-mentioned second feed port 1103. Based on this, the slurry can enter and exit the inner cavity of the iron removal chamber 11 through the first opening 1101 of the iron removal chamber 11, that is, the first opening 1101 can be used as the inlet and outlet of the slurry.

[0107] The magnetic member 21 can perform cleaning in the cleaning chamber 12. Specifically, the magnetic member 21 can remove metal impurities on the magnetic member 21 in the cleaning chamber 12. It should be noted that removing the metal impurities on the magnetic member 21 can facilitate the recovery of the magnetic attraction ability of the magnetic member 21, thereby facilitating the magnetic member 21 to re-enter the iron removal chamber 11 to magnetically attract the metal impurities in the slurry. In this way, the magnetic member 21 can repeatedly remove metal impurities, that is, it can repeatedly clean the slurry.

[0108] The iron removal device 100 provided in the embodiment of the present application can first extend the magnetic element 21 into the iron removal chamber 11 when working, and pass the slurry into the iron removal chamber 11, so that the magnetic element 21 can magnetically attract the metal impurities in the slurry in the iron removal chamber 11, thereby achieving the effect of removing the metal impurities in the slurry. Then, the magnetic element 21 is removed from the iron removal chamber 11, and the magnetic element 21 is extended into the cleaning chamber 12, so that the magnetic element 21 is cleaned in the cleaning chamber 12, thereby removing the metal impurities on the magnetic element 21. Subsequently, the magnetic element 21 is removed from the cleaning chamber 12, and the magnetic element 21 is extended into the iron removal chamber 11, the slurry in the iron removal chamber 11 is discharged, and new slurry is passed in, so that the cleaned magnetic element 21 can remove the metal impurities from the new slurry. Then, the magnetic element 21 is removed from the iron removal chamber 11, and the magnetic element 21 is extended into the cleaning chamber 12 for cleaning work... and so on, so that the magnetic element 21 moves alternately into the iron removal chamber 11 and the cleaning chamber 12, thereby alternately performing the removal of metal impurities and the cleaning of the magnetic element 21.

[0109] With such an arrangement, the magnetic element 21 can be alternately moved into the iron removal chamber 11 and the cleaning chamber 12, and can alternately realize the magnetic attraction work of the magnetic element 21 on metal impurities or the cleaning work of the magnetic element 21. In this way, there is no need to replace the magnetic element 21 after the magnetic element 21 has attracted more metal impurities, so that the magnetic element 21 can be inserted into the iron removal chamber 11 again to magnetically attract metal impurities with better magnetic attraction ability, which reduces the replacement process of the magnetic element 21. In addition, there is no need for excessive manual intervention in the magnetic attraction work and cleaning work of the magnetic element 21, which saves manpower. Therefore, the iron removal device 100 has a high degree of automation performance, which helps to improve the working efficiency of the iron removal device 100.

[0110] In addition, the iron removal device 100 can not only remove metal impurities from the slurry, but also take into account the cleaning function of the magnetic component 21. When it is necessary to magnetically absorb the metal impurities in the slurry, it is only necessary to move the magnetic component 21 into the iron removal chamber 11. When it is necessary to clean the metal impurities on the magnetic component 21, the magnetic component 21 can be moved into the cleaning chamber 12 for cleaning. In this way, after the magnetic component 21 completes the cleaning work in the cleaning chamber 12, it can magnetically absorb the metal impurities with better magnetic attraction when it is extended into the iron removal chamber 11 again, so that the slurry in the iron removal chamber 11 can be continuously updated to continuously remove metal impurities through the magnetic component 21, that is, the metal impurity removal work of the slurry can be continuously carried out. In this way, it helps to improve the cleaning efficiency of the slurry, thereby increasing the production capacity of the slurry. In addition, the magnetic element 21 can move alternately into the iron removal chamber 11 and the cleaning chamber 12, thereby alternately realizing the magnetic attraction work of the magnetic element 21 on metal impurities or the cleaning work of the magnetic element 21, making the operation of the iron removal device 100 very simple, and also helping to improve the cleaning efficiency of the slurry to increase the production capacity of the slurry.

[0111] It should be noted that in some implementations, the slurry can be introduced into the iron removal chamber 11 after the magnetic element 21 moves into the iron removal chamber 11, that is, the magnetic element 21 first moves into the iron removal chamber 11, and the slurry is then introduced into the iron removal chamber 11. Based on this, after the magnetic element 21 completes the magnetic attraction of the metal impurities in the slurry in the iron removal chamber 11, the slurry can be discharged before the magnetic element 21 moves out of the iron removal chamber 11, or the slurry can be discharged after the magnetic element 21 moves out of the iron removal chamber 11 and before the magnetic element 21 completes the cleaning work and re-enters the iron removal chamber 11, or even after the magnetic element 21 completes the cleaning work and re-enters the iron removal chamber 11, the slurry can be discharged, and then new slurry can be introduced after the magnetic element 21 moves into the iron removal chamber 11. In other implementations, the slurry may also be passed into the iron removal chamber 11 before the magnetic member 21 moves into the iron removal chamber 11, that is, the slurry is first passed into the iron removal chamber 11, and the magnetic member 21 then moves into the iron removal chamber 11. Based on this, after the magnetic member 21 completes the magnetic attraction work on the metal impurities in the slurry in the iron removal chamber 11, the slurry may be discharged before the magnetic member 21 moves out of the iron removal chamber 11, or the slurry may be discharged after the magnetic member 21 moves out of the iron removal chamber 11 and before the magnetic member 21 completes the cleaning work and re-enters the iron removal chamber 11, and then new slurry is passed into the iron removal chamber 11 before the magnetic member 21 moves into the iron removal chamber 11.

[0112] In some embodiments, please refer to Figures 2, 3, 5, and 6. Figure 5 shows a partial enlarged view of Figure 2, specifically showing a three-dimensional view of the cleaning chamber 12 and the scraper 13. Figure 6 shows a partial enlarged view of Figure 3, specifically showing a top view of the cleaning chamber 12 and the scraper 13. The cleaning mechanism 10 also includes a scraper 13, which is used to scrape metal impurities on the magnetic element 21 into the cleaning chamber 12.

[0113] It can be understood that the scraper 13 can move relative to the magnetic member 21 to scrape the metal impurities on the magnetic member 21 into the cleaning chamber 12, thereby achieving the cleaning work of the magnetic member 21, that is, achieving the effect that the magnetic member 21 can be cleaned in the cleaning chamber 12.

[0114] The scraper 13 can move in various ways relative to the magnetic member 21. In some implementations, when the magnetic member 21 moves out of the cleaning chamber 12, the scraper 13 can be fixed relative to the cleaning chamber 12 along the direction in which the magnetic member 21 enters and exits the cleaning chamber 12, and abuts against the surface of the magnetic member 21, so that the metal impurities on the surface of the magnetic member 21 can be scraped off into the cleaning chamber 12 by the scraper 13. In other implementations, when the magnetic member 21 is extended into the cleaning chamber 12 or when the magnetic member 21 is moved out of the cleaning chamber 12, the scraper 13 can move in a direction opposite to the direction in which the magnetic member 21 moves out of the cleaning chamber 12, and abut against the surface of the magnetic member 21, so that the metal impurities on the surface of the magnetic member 21 can be scraped off into the cleaning chamber 12.

[0115] The direction in which the magnetic element 21 enters and exits the cleaning chamber 12 is parallel to the direction Y shown in the figure.

[0116] By adopting the above-mentioned technical solution, after the magnetic element 21 completes the magnetic attraction work on the metal impurities in the slurry in the iron removal chamber 11, when the magnetic element 21 is extended into the cleaning chamber 12 or when the magnetic element 21 is moved out of the cleaning chamber 12, the scraper 13 can scrape the metal impurities on the surface of the magnetic element 21 into the cleaning chamber 12 to clean the magnetic element 21, thereby restoring the magnetic attraction ability of the magnetic element 21, so that when the magnetic element 21 is extended into the iron removal chamber 11 again, it can remove the metal impurities again with better magnetic attraction ability.

[0117] In this way, the cleaning of the magnetic member 21 is achieved by the scraper 13, making the cleaning of the magnetic member 21 very simple and easy to achieve. This helps to improve the cleaning efficiency of the magnetic member 21, thereby improving the cleaning efficiency and production capacity of the slurry.

[0118] It should be noted that when the scraper 13 is used to scrape off metal impurities on the surface of the magnetic member 21 during the process of the magnetic member 21 being removed from the cleaning chamber 12, thereby cleaning the magnetic member 21, the magnetic member 21 can be cleaned by quickly extending the magnetic member 21 into and out of the cleaning chamber 12. In this way, the magnetic member 21 does not need to stay in the cleaning chamber 12, and there is no need to spend too much extra time cleaning the magnetic member 21, which can effectively improve the cleaning efficiency of the magnetic member 21, thereby improving the cleaning efficiency and production capacity of the slurry.

[0119] In some embodiments, referring to Figures 2, 3, 5, and 6, the scraper 13 includes a plurality of scraping portions 131. The scraping portions 131 are capable of moving toward or away from each other, and after moving toward each other, the scraping portions 131 can grip the magnetic member 21. The magnetic member 21 can move relative to the scraping portions 131 in the direction of entering and exiting the cleaning chamber 12, allowing the scraping portions 131 to scrape off metal impurities when exiting the cleaning chamber 12.

[0120] As shown in Figures 5 and 6, each scraper 13 has two scraping portions 131, but may also have three or more. The scraping portions 131 may be plate-shaped or block-shaped, and the specific shape of the scraping portions 131 is not limited herein.

[0121] When the magnetic member 21 is extended into the cleaning chamber 12, the multiple scraping portions 131 move toward each other, as shown in Figures 2 and 5. The multiple scraping portions 131 embrace the magnetic member 21, so that the multiple scraping portions 131 are all against the surface of the magnetic member 21. At this time, when the magnetic member 21 moves out of the cleaning chamber 12, the magnetic member 21 moves relative to the scraping portions 131, so that the multiple scraping portions 131 can all scrape the metal impurities on the surface of the magnetic member 21 into the cleaning chamber 12. In the process of the magnetic member 21 moving out of the cleaning chamber 12, the scraping portions 131 can be fixed relative to the cleaning chamber 12 along the direction (direction Y) in which the magnetic member 21 enters and exits the cleaning chamber 12, or can move in the direction opposite to the direction in which the magnetic member 21 moves out of the cleaning chamber 12.

[0122] After the multiple scraping parts 131 move toward each other, the multiple scraping parts 131 can define a through groove 1301, which passes through the scraping part 13 along the direction in which the magnetic part 21 enters and exits the cleaning chamber 12. At this time, when the magnetic part 21 extends into the cleaning chamber 12, the magnetic part 21 is inserted into the through groove 1301 along the direction in which it enters and exits the cleaning chamber 12, so that the multiple scraping parts 131 embrace the outer periphery of the magnetic part 21 around the first axis, so that the multiple scraping parts 131 are in contact with and abut against the outer peripheral surface of the magnetic part 21 around the first axis. In this way, when the magnetic part 21 moves out of the cleaning chamber 12, so that the multiple scraping parts 131 scrape off the metal impurities on the outer peripheral surface of the magnetic part 21, the multiple scraping parts 131 can contact various positions on the outer peripheral surface of the magnetic part 21 around the first axis, thereby reducing the cleaning blind spots of the magnetic part 21 and effectively improving the cleaning rate of the scraping part 13 on the magnetic part 21. The first axis described herein is parallel to the direction in which the magnetic member 21 enters and exits the cleaning chamber 12, as shown in the direction Y in the figure. Furthermore, the first axis described herein is the first rotation axis L1 involved in the following embodiments, specifically the axis L1 shown in Figure 8 . Figure 8 shows an enlarged partial view of Figure 2 , specifically illustrating the schematic structure of the magnetic member 21 and the iron removal chamber 11.

[0123] As shown in Figures 5 to 7, Figure 7 shows a partial enlarged view of Figure 4, specifically showing a front view of the cooperation between the scraper 13 and the cleaning chamber 12. A plurality of scraping portions 131 are provided at the second opening 1201 of the cleaning chamber 12. Before the magnetic member 21 is inserted into the cleaning chamber 12, the plurality of scraping portions 131 can move backward to avoid the second opening 1201, so as to facilitate the magnetic member 21 to be inserted into the cleaning chamber 12. When the magnetic member 21 is inserted into the cleaning chamber 12, the plurality of scraping portions 131 move toward each other and hold the magnetic member 21, and the through groove 1301 defined by the plurality of scraping portions 131 is opposite to the second opening 1201 along the direction in which the magnetic member 21 enters and exits the cleaning chamber 12.

[0124] By adopting the above technical solution, during the operation of the iron removal device 100, the multiple scraping parts 131 can first move backward to avoid the second opening 1201 of the cleaning chamber 12. Then, the magnetic member 21 extends into the cleaning chamber 12 through the second opening 1201. Subsequently, the multiple scraping parts 131 move toward each other to hold the magnetic member 21. Then, the magnetic member 21 moves out of the cleaning chamber 12, so that the multiple scraping parts 131 scrape the metal impurities on the magnetic member 21 into the cleaning chamber 12. Afterwards, the magnetic member 21 extends into the iron removal chamber 11, and the multiple scraping parts 131 move backward, so that the magnetic member 21 can move out of the iron removal chamber 11 again and extend into the cleaning chamber 12 after magnetically attracting the metal impurities in the iron removal chamber 11.

[0125] In the iron removal device 100 provided in the embodiment of the present application, the multiple scraping parts 131 can move in opposite directions before the magnetic member 21 is inserted into the cleaning chamber 12, and can move toward each other after the magnetic member 21 is inserted into the cleaning chamber 12 to hold the magnetic member 21. This makes the movement of the multiple scraping parts 131 very flexible and can be set to hold the position of the magnetic member 21 where there are no magnetic metal impurities after the magnetic member 21 is inserted into the cleaning chamber 12. In this way, when the multiple scraping parts 131 hold the magnetic member 21 and the magnetic member 21 is moved out of the cleaning chamber 12, the multiple scraping parts 131 can completely contact and resist the position of the magnetic member 21 with metal impurities, so that all metal impurities on the magnetic member 21 can be scraped off as much as possible, thus reducing the cleaning blind spot of the magnetic member 21 and improving the cleaning effect of the magnetic member 21. In addition, the assembly requirements and motion control requirements for the scraping parts 131 are relatively low, and there is no need to have high requirements for the precise movement of the multiple scraping parts 131 in opposite directions. After the magnetic element 21 is inserted into the cleaning chamber 12, the scraping portions 131 only need to be moved toward each other until they embrace the magnetic element 21. After the magnetic element 21 is removed from the cleaning chamber 12, the scraping portions 131 only need to be moved away from each other until they reach the desired position. This makes the scraping element 13 very easy to maintain and reduces production costs.

[0126] In some embodiments, as shown in Figures 5 and 7, the scraping portion 131 is located outside the cleaning chamber 12. When the magnetic member 21 extends into the cleaning chamber 12, the multiple scraping portions 131 embrace the portion of the magnetic member 21 outside the cleaning chamber 12 after moving toward each other. In this way, the portion of the magnetic member 21 outside the cleaning chamber 12 can be set as the portion of the magnetic member 21 that is not used to magnetically attract metal impurities. In this way, when the multiple scraping portions 131 embrace the magnetic member 21 and the magnetic member 21 moves out of the cleaning chamber 12, the multiple scraping portions 131 can completely contact and resist the position of the magnetic member 21 with metal impurities, thereby improving the cleaning rate of the magnetic member 21 and reducing the cleaning dead angle of the magnetic member 21.

[0127] In some embodiments, the directions of movement of the scraping portions 131 toward and away from each other can be perpendicular to the direction in which the magnetic element 21 enters and exits the cleaning chamber 12. This facilitates the scraping portions 131 to engage or release the magnetic element 21. For example, as shown in Figures 5 and 6, when there are two scraping portions 131, the directions of movement of the scraping portions 131 toward and away from each other are parallel to the direction X shown in the figures, which is perpendicular to the direction Y.

[0128] In some embodiments, please refer to Figures 5 and 6 together. Multiple scrapers 131 define a through groove 1301 for holding the magnetic element 21. A protrusion structure 1311 is provided on the inner circumference of the through groove 1301, and the scraper 131 supports the magnetic element 21 through the protrusion structure 1311.

[0129] It can be understood that the through groove 1301 described in this embodiment is the same as the through groove 1301 described above. Specifically, when the magnetic member 21 extends into the cleaning chamber 12, the multiple scraping portions 131 move toward each other to define the above-mentioned through groove 1301, and the magnetic member 21 is inserted into the through groove 1301 to achieve the effect of multiple scraping portions 131 holding the magnetic member 21. At this time, the protruding structure 1311 abuts against and contacts the surface of the magnetic member 21. In the process of the magnetic member 21 moving out of the cleaning chamber 12, the protruding structure 1311 scrapes the metal impurities on the surface of the magnetic member 21 into the cleaning chamber 12, thereby achieving the cleaning of the magnetic member 21.

[0130] By adopting the above technical solution, by setting a protruding structure 1311 on the inner peripheral side of the through groove 1301, the friction between the scraping portion 131 and the magnetic component 21 can be increased, thereby increasing the force of the scraping portion 131 to scrape off metal impurities on the surface of the magnetic component 21, thereby improving the cleaning effect of the magnetic component 21.

[0131] 6 , the protrusion structure 1311 may be a microstructure provided on the scraping portion 131 , and the microstructure may be provided on the inner circumference of the through groove 1301 . For example, the microstructure may be similar to a thread structure.

[0132] In other embodiments, the protruding structure 1311 may also be a buffer structure. Specifically, the protruding structure 1311 has a certain buffering performance, for example, the protruding structure 1311 may be a rubber ring, a silicone ring, etc.

[0133] By adopting the above technical solution, by providing a microstructure or a buffer structure on the scraping portion 131 , the friction between the scraping portion 131 and the magnetic element 21 can be effectively increased, so that the scraping portion 131 has a higher cleaning effect on the magnetic element 21 .

[0134] In some embodiments, please refer to FIG. 5 to FIG. 7 , the cleaning mechanism 10 further includes a first driving structure 14 , and the first driving structure 14 is used to drive the plurality of scraping parts 131 to move toward each other or away from each other.

[0135] The first driving structure 14 refers to a component or assembly that can achieve a driving effect on the scraping portion 131 .

[0136] By adopting the above technical solution, the first driving structure 14 drives the multiple scraping parts 131 to move toward or away from each other, which can effectively reduce the manual intervention in the cleaning work of the magnetic member 21, improve the degree of automation of the cleaning work of the cleaning mechanism 10 on the magnetic member 21, and thus improve the working efficiency of the iron removal device 100. It can be understood that the scraping part 131 can clean the magnetic member 21 under the drive of the first driving structure 14. Then, when the magnetic member 21 is moved out of the iron removal chamber 11 and extends into the cleaning chamber 12, the magnetic member 21 is moved out of the cleaning chamber 12 again. During this process, the iron removal device 100 can automatically clean the magnetic member 21, thereby improving the cleaning efficiency of the magnetic member 21 and further improving the working efficiency of the iron removal device 100.

[0137] In some embodiments, the iron removal device 100 can also be used in conjunction with a control device. Specifically, the control device is electrically connected to the first drive structure 14, and the control device sends a control instruction to the first drive structure 14, and the first drive structure 14 executes the above-mentioned control instruction to drive the multiple scraping parts 131 to move toward each other or away from each other. The control device refers to a device that can directly send control instructions and receive signals, for example, it can be a computer that can send control instructions and receive data. For example, the control device sends a control instruction to the first drive structure 14 so that the first drive structure 14 drives the multiple scraping parts 131 to move toward each other. After the multiple scraping parts 131 hold the magnetic element 21, the first drive structure 14 sends a signal to the control device, and the control device receives the signal sent by the first drive structure 14 and stops controlling the first drive structure 14. Among them, the control device and the first drive structure 14 can be connected by wired electricity or by wireless communication. Such an arrangement improves the degree of automation of the cleaning work of the magnetic element 21, making the cleaning work of the magnetic element 21 very time-saving and labor-saving, which is conducive to improving the working efficiency of the iron removal device 100.

[0138] In some embodiments, referring to Figures 5 to 7 , the first drive structure 14 includes a first driver 141 and a drive base 142. The drive base 142 defines a plurality of slide grooves 1421, along which the scraping portions 131 can slide, respectively, toward or away from each other. The first driver 141 is configured to drive the drive base 142 to move, thereby causing the scraping portions 131 to slide along the slide grooves 1421.

[0139] It is understandable that, when the first driver 141 drives the drive seat 142 to move the drive seat 142, the multiple scraping parts 131 slide along the multiple chute 1421 in a one-to-one correspondence, thereby achieving the multiple scraping parts 131 to move toward each other or move away from each other. Specifically, the multiple chute 1421 has a first end and a second end relative to each other, and the distance between two adjacent chute 1421 gradually increases from the first end to the second end. When the multiple scraping parts 131 slide along the corresponding chute 1421 toward the first end, the distance between the multiple scraping parts 131 gradually decreases, that is, the multiple scraping parts 131 move toward each other. When the multiple scraping parts 131 slide along the corresponding chute 1421 toward the second end, the distance between the multiple scraping parts 131 gradually increases, that is, the multiple scraping parts 131 move away from each other.

[0140] To facilitate description of the sliding of the scraping portion 131, this embodiment is described by taking the example of two scraping portions 131. Accordingly, the number of the sliding grooves 1421 on the driving seat 142 is also two.

[0141] Here, the direction in which the magnetic element 21 enters and exits the cleaning chamber 12 is defined as the first direction Y, such as the direction Y shown in the figure. The directions of the two scraping parts 131 moving toward each other and moving away from each other are defined as the second direction X, such as the direction X shown in the figure. In this embodiment, the scraping part 131 can move relative to the cleaning chamber 12 along the second direction X, so that the two scraping parts 131 can move toward each other or away from each other along the second direction X. In addition, the scraping part 131 is fixed relative to the cleaning chamber 12 along the first direction Y, and the scraping part 131 is also fixed relative to the cleaning chamber 12 along the third direction Z. In addition, the two slide grooves 1421 are spaced apart along the second direction X, and the distance between the two slide grooves 1421 along the second direction X gradually increases from the first end to the second end. Among them, the third direction Z is any direction that intersects the first direction Y and the second direction X respectively. For example, the third direction Z can be the direction Z shown in Figure 6. The third direction Z can be a straight direction or a curved direction.

[0142] When the first driver 141 drives the drive base 142 to move, the drive base 142 can move along the third direction Z, that is, the drive base 142 moves along a direction intersecting the first direction Y and the second direction X. At this time, the scraping portion 131 is fixed relative to the cleaning chamber 12 along the first direction Y and the third direction Z, and can only move along the second direction X. The scraping portion 131 slides along the corresponding slide groove 1421, thereby achieving the two scraping portions 131 to move toward each other or away from each other.

[0143] The first driver 141 is a component for driving the driving base 142 to move. The first driver 141 can have various structures.

[0144] In some embodiments, when the first driver 141 is used to drive the driving seat 142 to move in a curve, that is, when the third direction Z is a curve direction, the first driver 141 can be a rotating motor, a combination mechanism formed by a rotating motor and a transmission part, etc.

[0145] For example, as shown in Figures 5 to 7, in this embodiment, the first drive structure 14 further includes a turntable 143, which is disposed at the output end of the first driver 141. The first driver 141 is configured to drive the turntable 143 to rotate. A drive base 142 is disposed on the turntable 143 and is capable of rotating synchronously with the turntable 143 as the turntable 143 rotates. Thus, when the turntable 143 rotates under the drive of the first driver 141, the drive base 142 rotates synchronously with the turntable 143, thereby achieving a curved motion effect, thereby enabling the drive base 142 to move in a curved motion along the third direction Z.

[0146] 5 to 7 , the rotation axis of the turntable 143 may be parallel to the first direction Y. In some implementations, as shown in FIG5 to 7 , the first direction Y may also be perpendicular to the second direction X.

[0147] By adopting the above technical solution, the first driver 141 rotates through the driving turntable 143 to realize the movement of the driving seat 142 in the third direction Z, thereby realizing the toward or away movement of at least two scraping parts 131, so that the movement operation of the scraping part 131 is very stable.

[0148] In other embodiments, when the first driver 141 is used to drive the driving seat 142 to move linearly, that is, when the third direction Z is a linear direction, the first driver 141 can be a combination mechanism formed by a cylinder, an electric cylinder, a linear motor, a rotary motor and a screw mechanism.

[0149] By adopting the above technical solution, on the one hand, after the magnetic element 21 is removed from the iron removal chamber 11 and extended into the cleaning chamber 12, the first driver 141 can drive the drive seat 142 to move, causing the multiple scraping portions 131 to move toward each other to embrace the magnetic element 21. As the magnetic element 21 is removed from the cleaning chamber 12, the multiple scraping portions 131 can clean the magnetic element 21. In this way, the iron removal device 100 can automatically clean the magnetic element 21, thereby improving the operating efficiency of the iron removal device 100. On the other hand, as the first driver 141 drives the drive seat 142 to move, the multiple scraping portions 131 can slide along the corresponding chute 1421, thereby providing a motion guidance effect for the scraping portions 131 and improving the motion stability of the scraping portions 131. This allows the multiple scraping portions 131 to flexibly move toward or away from each other, thereby improving the operational flexibility of the iron removal device 100.

[0150] In some embodiments, referring to both Figures 5 and 6 , the scraping portion 131 is rotatably connected to a connecting shaft 144, which is disposed in a corresponding slide groove 1421 and is capable of sliding along the corresponding slide groove 1421. It is understood that when the first driver 141 drives the drive base 142 to move, the connecting shaft 144 slides along the corresponding slide groove 1421, thereby achieving movement of the scraping portion 131, thereby achieving the movement of the multiple scraping portions 131 toward each other or away from each other.

[0151] In other embodiments, a protruding column may be provided on the scraping portion 131, and the protruding column is inserted into the corresponding sliding groove 1421 and can slide along the corresponding sliding groove 1421. In this case, the protruding column can be arranged not to rotate relative to the scraping portion 131, that is, the scraping portion 131 and the protruding column are fixed to each other.

[0152] In some embodiments, as shown in Figures 2 to 7, the cleaning mechanism 10 includes multiple cleaning chambers 12, each of which is provided with a scraper 13. In other words, the cleaning mechanism 10 includes multiple scrapers 13, and the multiple scrapers 13 correspond one-to-one to the multiple cleaning chambers 12. Correspondingly, multiple drive seats 142 can also be provided, and the multiple drive seats 142 correspond one-to-one to the multiple scrapers 13.

[0153] In addition, multiple cleaning chambers 12 are distributed on the outer periphery of the turntable 143 around the rotation axis of the turntable 143, and multiple drive seats 142 are all arranged on the turntable 143, and multiple drive seats 142 are circumferentially distributed on the outer peripheral edge of the turntable 143 around the rotation axis of the turntable 143, so that at least a portion of each drive seat 142 can be located correspondingly in each cleaning chamber 12. When the first driver 141 is driven, the turntable 143 rotates and drives the multiple drive seats 142 to move, thereby causing the scraping portions 131 of the multiple scrapers 13 to move. This arrangement allows the scrapers 13 at the multiple cleaning chambers 12 to move synchronously, so that when there are magnetic elements 21 in multiple cleaning chambers 12, the cleaning work of the magnetic elements 21 in the multiple cleaning chambers 12 can be achieved simultaneously. In addition, this also makes the driving of the scraper 13 very simple, thereby making the overall structure of the iron removal device 100 simple.

[0154] In some embodiments, referring to FIG. 1 and FIG. 2 , the iron removal device 100 further includes a sewage pipe 40 . The sewage pipe 40 is connected to the cleaning chamber 12 and is used to discharge metal impurities in the cleaning chamber 12 .

[0155] It is understandable that the sewage pipe 40 is connected to the cleaning chamber 12 and communicates with the inner cavity of the cleaning chamber 12 .

[0156] It should be noted that after the magnetic member 21 cleans the cleaning chamber 12, the metal impurities on the magnetic member 21 are removed and contained in the cleaning chamber 12. The metal impurities in the cleaning chamber 12 generally refer to the metal impurities remaining in the cleaning chamber 12 after the magnetic member 21 is cleaned.

[0157] By adopting the above technical solution, when the clean chamber 12 contains a large amount of metal impurities, the metal impurities in the clean chamber 12 can be discharged through the sewage pipe 40. In this way, the clean chamber 12 can have a larger space to accommodate metal impurities, and the clean chamber 12 can be reused repeatedly. Moreover, by discharging the metal impurities in the clean chamber 12 through the sewage pipe 40, the clean chamber 12 is cleaned, and the clean chamber 12 can be reused repeatedly without excessive human intervention in the cleaning work of the clean chamber 12. In this way, the automation performance of the iron removal device 100 is also improved, saving time and labor, and also improving the working efficiency of the iron removal device 100.

[0158] The drain pipe 40 can be connected to the external environment or to an external waste collection device. Thus, when metal impurities within the cleaning chamber 12 are discharged through the drain pipe 40, they can be discharged to the external environment or to a designated location such as a waste collection device. The drain pipe 40 can be a single pipe or a combination of multiple pipes connected in sequence.

[0159] In some implementations, the metal impurities in the cleaning chamber 12 can be directly discharged through the sewage pipe 40 under the action of gravity. In other implementations, the sewage pipe 40 can also be provided with a pumping device such as a pressure pump, which can pump the metal impurities in the cleaning chamber 12, so that the metal impurities in the cleaning chamber 12 are discharged through the sewage pipe 40. In still other implementations, a water supply device can be connected to the cleaning chamber 12. When it is necessary to clean the metal impurities in the cleaning chamber 12, the water supply device can supply water to the cleaning chamber 12 so that the water drives the metal impurities in the cleaning chamber 12 to be discharged through the sewage pipe 40. In this case, the water can drive the metal impurities to be discharged through the sewage pipe 40 under the pumping action of the above-mentioned pumping device, or directly drive the metal impurities to be discharged through the sewage pipe 40 under the action of gravity. It should be added here that by using a pumping device to assist in discharging metal impurities in the cleaning chamber 12, the cleaning work of the cleaning chamber 12 can be made very simple, convenient and easy to implement, thereby greatly improving the degree of automation of the iron removal device 100, eliminating the need for manual intervention in the work of the cleaning chamber 12, and thereby improving the working efficiency of the iron removal device 100.

[0160] In some embodiments, when there are multiple cleaning chambers 12, each of the multiple cleaning chambers 12 can be connected to a separate sewage pipe 40. Of course, the sewage pipe 40 can also be connected to multiple cleaning chambers 12, which can simplify the arrangement of the sewage pipe 40 and the structure of the iron removal device 100.

[0161] In some embodiments, please refer to Figures 2 and 9 together. Figure 9 shows a cross-sectional view of the magnetic member 21 entering the iron removal chamber 11. The cross-sectional view is perpendicular to the direction in which the magnetic member 21 enters and exits the iron removal chamber 11. The inner cavity of the iron removal chamber 11 is cylindrical, the magnetic member 21 is shaft-shaped, and the difference between the diameter of the inner cavity of the iron removal chamber 11 and the diameter of the magnetic member 21 is less than 50 mm.

[0162] The inner cavity of the iron removal chamber 11 is cylindrical, and the magnetic member 21 is shaft-shaped. Based on this, when the magnetic member 21 enters the inner cavity of the iron removal chamber 11, on the cross section of the magnetic member 21 and the iron removal chamber 11 perpendicular to the axial direction of the magnetic member 21, the inner cavity of the magnetic member 21 and the iron removal chamber 11 are both circular, as shown in Figure 9. Among them, the diameter of the inner cavity of the iron removal chamber 11 is D1 as shown in the figure, and the diameter of the magnetic member 21 is D2 as shown in the figure.

[0163] In this embodiment, the axial directions of the iron removal chamber 11 and the magnetic member 21 are parallel to the direction in which the magnetic member 21 enters and exits the iron removal chamber 11 .

[0164] It should be noted that, in order to allow the magnetic member 21 to enter and exit the iron removal chamber 11, the diameter of the inner cavity of the iron removal chamber 11 is larger than the diameter of the magnetic member 21. Based on this, the difference between the diameter of the inner cavity of the iron removal chamber 11 and the diameter of the magnetic member 21 is less than 50 mm, that is, D1-D2 is less than 50 mm, and can specifically be 40 mm, 30 mm, etc.

[0165] By adopting the above technical solution, the difference between the diameter of the inner cavity of the iron removal chamber 11 and the diameter of the magnetic element 21 is within a predetermined range and is not too large. In this way, on the basis that the inner cavity of the iron removal chamber 11 can simultaneously accommodate the slurry and the magnetic element 21, the slurry in the iron removal chamber 11 is not excessive. In this way, the magnetic element 21 can fully contact the slurry and fully magnetically attract the metal impurities in the slurry, thereby effectively improving the cleaning effect of the magnetic element 21 on the slurry.

[0166] In some embodiments, please refer to Figures 2 and 4 together. The iron removal chamber 11 has a first feed port 1102, which is located at the end of the iron removal chamber 11 along the direction in which the magnetic suction member 21 enters and exits the iron removal chamber 11, and the first feed port 1102 can allow slurry to enter.

[0167] The first feed port 1102 is connected to the inner cavity of the iron removal chamber 11. In some implementations, the first feed port 1102 can serve as an inlet of the iron removal chamber 11 for the slurry to enter. Specifically, the slurry can enter the iron removal chamber 11 from the first feed port 1102. In other embodiments, the slurry in the iron removal chamber 11 can also flow out of the iron removal chamber 11 through the first feed port 1102. It should be noted here that the first feed port 1102 involved in this embodiment is the same as the first feed port 1102 involved in the above embodiments. Please refer to the above description for details, and no further details will be given here.

[0168] The direction in which the magnetic member 21 enters and exits the iron removal chamber 11 is parallel to the direction Y shown in the figure, that is, the direction in which the magnetic member 21 enters and exits the iron removal chamber 11 is roughly parallel to the direction in which the magnetic member 21 enters and exits the cleaning chamber 12. When the magnetic member 21 is a long strip structure, the extension direction (length direction) of the magnetic member 21 is roughly parallel to the direction in which the magnetic member 21 enters and exits the iron removal chamber 11, that is, roughly parallel to the direction Y. When the magnetic member 21 is a magnetic rod, the axial direction of the magnetic rod is parallel to the direction Y.

[0169] By adopting the above technical solution, the first feed port 1102 is provided at the end of the iron removal chamber 11 along the direction in which the magnetic element 21 enters and exits the iron removal chamber 11. In this way, after the slurry enters the iron removal chamber 11 from the first feed port 1102, in order to fill the inner cavity of the iron removal chamber 11 with the slurry, the slurry flows in the iron removal chamber 11 roughly along a direction parallel to the direction in which the magnetic element 21 enters and exits the iron removal chamber 11, that is, the slurry flows in the iron removal chamber 11 roughly along a direction Y to fill the iron removal chamber 11. In this way, when the magnetic element 21 extends into the iron removal chamber 11, when the slurry flows in the iron removal chamber 11 along a direction (direction Y) parallel to the direction in which the magnetic element 21 enters and exits the iron removal chamber 11, the slurry can better flow to the end of the magnetic element 21 entering the iron removal chamber 11 along the direction Y, and flow to the outer peripheral surface of the magnetic element 21 around the first axis, thereby reducing the magnetic blind area of ​​the magnetic element 21 and improving the magnetic attraction efficiency of metal impurities.

[0170] It should be noted here that, in some cases, the slurry flows in a direction perpendicular to the length direction of the magnetic element 21. In this way, a blind spot for magnetically attracting metal impurities will appear on one side of the magnetic element 21 along the flow direction of the slurry, and the magnetic attraction of the metal impurities cannot be efficiently achieved. In the iron removal device 100 provided in the embodiment of the present application, the flow direction of the slurry is roughly parallel to the extension direction of the magnetic element 21, so that the slurry can fully contact the surface of the magnetic element 21 during the flow process, so that the magnetic element 21 can magnetically attract metal impurities at each position where it extends into the iron removal chamber 11, thereby reducing the adsorption blind spot of the magnetic element 21, improving the magnetic attraction efficiency of the magnetic element 21 for metal impurities, and further improving the efficiency of the iron removal device 100 in removing metal impurities from the slurry.

[0171] In some embodiments, please refer to Figures 2 and 4 together, and in combination with other figures, the iron removal chamber 11 also has a second feed port 1103, the first feed port 1102 and the second feed port 1103 are respectively arranged at the two ends of the iron removal chamber 11 along the direction of the magnetic suction part 21 entering and exiting the iron removal chamber 11, and any one of the first feed port 1102 and the second feed port 1103 is used for slurry to enter, and the other is used for slurry to flow out.

[0172] It can be understood that the slurry can enter the iron removal chamber 11 through the first pass port 1102 and flow out of the iron removal chamber 11 through the second pass port 1103, or enter the iron removal chamber 11 through the second pass port 1103 and flow out of the iron removal chamber 11 through the first pass port 1102.

[0173] By adopting the above technical solution, by arranging the first feed port 1102 and the second feed port 1103 at the two ends of the iron removal chamber 11 along the direction in which the magnetic element 21 enters and exits the iron removal chamber 11, the flow direction of the slurry in the iron removal chamber 11 can be made roughly parallel to the distribution direction of the first feed port 1102 and the second feed port 1103. In this way, the adsorption blind area of ​​the magnetic element 21 can be reduced, the magnetic attraction efficiency of the magnetic element 21 for metal impurities can be improved, and the efficiency of the iron removal device 100 in removing metal impurities from the slurry can be improved. In addition, by arranging the first feed port 1102 and the second feed port 1103 at the two ends of the iron removal chamber 11 along the direction in which the magnetic element 21 enters and exits the iron removal chamber 11, the connection and assembly of the iron removal chamber 11 and the external device for outputting and inputting slurry are facilitated.

[0174] In some embodiments, please refer to Figures 2, 3, 6 and 8 together. The iron removal chamber 11 has a first opening 1101 for the magnetic member 21 to enter and exit. The first opening 1101 described here is the same as the first opening 1101 involved in the above embodiments. Please refer to the above explanation for details, and the explanation will not be repeated here. The magnetic member 21 includes a magnetic body 211 and a sealing member 212 provided on the magnetic body 211. The magnetic body 211 is used to magnetically attract metal impurities, and the sealing member 212 is used to seal the first opening 1101 when the magnetic body 211 enters the iron removal chamber 11.

[0175] It is understood that after the magnetic member 21 is inserted into the iron removal chamber 11, the magnetic body 211 of the magnetic member 21 is inserted into the inner cavity of the iron removal chamber 11 and is able to magnetically attract metal impurities in the slurry in the iron removal chamber 11. In addition, the sealing member 212 seals the first opening 1101 of the iron removal chamber 11.

[0176] The seal 212 is arranged on the outer periphery of the magnetic body 211 around the first axis. When the magnetic body 211 is extended into the iron removal chamber 11, the seal 212 covers the first opening 1101 to fill the gap between the outer peripheral side of the magnetic body 211 and the inner side wall of the first opening 1101, thereby sealing the first opening 1101. The seal 212 can be a structural part such as a metal part or a plastic part. In some implementations, a sealing ring can also be provided on the seal 212, and the sealing ring is arranged around the outer periphery of the magnetic body 211. When the seal 212 seals the first opening 1101, the sealing ring is arranged around the outer periphery of the first opening 1101, and one end of the sealing ring along the axial direction abuts against the seal 212, and the other end of the sealing ring along the axial direction abuts against the iron removal chamber 11. In this way, the sealing ring can seal the gap between the seal 212 and the first opening 1101, which can improve the problem of slurry overflow. The sealing ring may be, but is not limited to, a rubber ring, a silicone ring, or other structures with a sealing function.

[0177] By adopting the above technical solution, when the magnetic component 21 is extended into the iron removal chamber 11, the sealing component 212 of the magnetic component 21 realizes the sealing of the first opening 1101 of the iron removal chamber 11, which can improve the problem of slurry in the iron removal chamber 11 overflowing from the first opening 1101.

[0178] In some embodiments, referring to Figures 2, 8, and 10 to 13, the seal 212 is provided with a first lock catch 213, and the iron removal chamber 11 is provided with a second lock catch 111. The first lock catch 213 can be locked with the second lock catch 111 to prevent the magnetic body 211 from being removed from the iron removal chamber 11. The first lock catch 213 can also be unlocked with the second lock catch 111 to allow the magnetic body 211 to be removed from the iron removal chamber 11.

[0179] It can be understood that the first lock buckle 213 and the second lock buckle 111 can be switched back and forth between a locked state and an unlocked state. When the magnetic element 21 extends into the iron removal chamber 11, the first lock buckle 213 and the second lock buckle 111 can be switched to a locked state, as shown in Figures 12 and 13. At this time, the magnetic body 211 is difficult to move out of the iron removal chamber 11 under the locking action of the first lock buckle 213 and the second lock buckle 111. Accordingly, the sealing member 212 is also difficult to detach from the iron removal chamber 11, making it difficult to open the first opening 1101. After the magnetic body 211 completes the magnetic attraction of metal impurities, the first lock buckle 213 and the second lock buckle 111 can be switched to an unlocked state, as shown in Figures 10 and 11. At this time, the magnetic body 211 can be removed from the iron removal chamber 11. Accordingly, the sealing member 212 can also detach from the iron removal chamber 11 with the magnetic body 211 to open the first opening 1101.

[0180] By adopting the above technical solution, when the magnetic element 21 is extended into the iron removal chamber 11, the first lock buckle 213 on the magnetic element 21 can be locked with the second lock buckle 111 on the iron removal chamber 11, thereby limiting the magnetic body 211 from moving out of the iron removal chamber 11 and limiting the sealing element 212 from opening the first opening 1101. In this way, the state in which the magnetic body 211 is extended into the iron removal chamber 11 can be better maintained to maintain the magnetic attraction work of the magnetic body 211 on the metal impurities in the iron removal chamber 11. In addition, the sealing state of the sealing element 212 to the first opening 1101 can also be maintained, thereby improving the problem of the sealing element 212 opening the first opening 1101 under the pressure of the slurry, causing the slurry to overflow.

[0181] In other embodiments, the first lock buckle 213 may be disposed on the magnetic body 211 , or the first lock buckle 213 may be fixed to both the magnetic body 211 and the sealing member 212 .

[0182] In some embodiments, please refer to Figures 8, 10, 11, and 13. Figure 8 shows a partial schematic diagram of the magnetic element 21 and the iron removal chamber 11. Figure 10 shows a schematic diagram of the magnetic element 21 and the iron removal chamber 11 in the unlocked state of the first lock catch 213 and the second lock catch 111. Figure 11 shows an enlarged partial view of Figure 10. Figure 12 shows a schematic diagram of the magnetic element 21 and the iron removal chamber 11 in the locked state of the first lock catch 213 and the second lock catch 111. Figure 13 shows an enlarged partial view of Figure 12. The second lock catch 111 is provided with a lock slot 1104. The magnetic body 211 can rotate about a first rotation axis L1, allowing the first lock catch 213 to rotate into the lock slot 1104 and be retained in the lock slot 1104 along a first direction Y, or allowing the first lock catch 213 to rotate out of the lock slot 1104. The first direction Y is parallel to the direction in which the magnetic body 211 enters and exits the iron removal chamber 11 and is parallel to the first rotation axis L1.

[0183] It can be understood that after the magnetic body 211 is extended into the iron removal chamber 11, the magnetic body 211 can be driven to rotate around the first rotation axis L1, so that the first lock buckle 213 is driven by the magnetic body 211 to rotate in the lock groove 1104 of the second lock buckle 111, so that the first lock buckle 213 is limited in the lock groove 1104 along the first direction Y, thereby realizing the locking of the first lock buckle 213 and the second lock buckle 111, as shown in Figures 12 and 13. Specifically, at this time, the first lock buckle 213 is limited between the two sides of the lock groove 1104 along the first direction Y, so that the first lock buckle 213 cannot move relative to the second lock buckle 111 along the first direction Y. Accordingly, the magnetic body 211 and the sealing member 212 cannot move relative to the iron removal chamber 11 along the first direction Y, and the magnetic body 211 cannot move out of the iron removal chamber 11 along the first direction Y, thereby maintaining the state of the magnetic body 211 in the iron removal chamber 11 and the state of the sealing member 212 sealing the first opening 1101. After the magnetic body 211 completes the magnetic attraction of metal impurities, the magnetic body 211 can be driven to rotate around the first rotation axis L1 to disengage the first lock buckle 213 from the lock groove 1104, thereby unlocking the first lock buckle 213 and the second lock buckle 111, as shown in Figures 10 and 11. At this time, the magnetic member 21 can be removed from the iron removal chamber 11.

[0184] By adopting the above technical solution, by providing the second lock buckle 111 with a locking groove 1104, the first lock buckle 213 can be limited by the locking groove 1104 on both sides along the first direction Y, thereby achieving the locking of the first lock buckle 213 and the second lock buckle 111. Based on this, when manufacturing the second lock buckle 111, it is only necessary to configure the second lock buckle 111 with a structure having a locking groove 1104, and the locking groove 1104 can limit the first lock buckle 213 on both sides along the first direction Y. When manufacturing the first lock buckle 213, it is only necessary to ensure that the first lock buckle 213 can enter the locking groove 1104. This makes the structure of the first lock buckle 213 and the second lock buckle 111 very simple and easy to manufacture. Furthermore, by driving the magnetic body 211 to rotate about the first rotation axis L1, the first lock buckle 213 and the second lock buckle 111 can be locked or unlocked. This makes the operation of switching the first lock buckle 213 and the second lock buckle 111 between the locked and unlocked states very simple and convenient, and easy to implement.

[0185] In some embodiments, please refer to Figures 2, 10, 14, and 14. Figure 14 shows a schematic diagram of the cooperation between the second drive structure 22 and the third drive structure 23. The iron removal mechanism 20 also includes a second drive structure 22, which is used to drive the magnetic body 211 to move, thereby driving the first lock 213 to lock or unlock relative to the second lock 111.

[0186] In some implementations, as shown in Figures 2 and 10 to 14, when the magnetic body 211 achieves locking or unlocking of the first lock buckle 213 and the second lock buckle 111 by rotating, the second drive structure 22 is a component or assembly for driving the magnetic body 211 to rotate. For example, the second drive structure 22 can be a rotating motor, a combined mechanism formed by a rotating motor and a transmission member, etc. Exemplarily, as shown in Figure 14, the second drive structure 22 includes a second driver 221, a rack 223 and a gear 222, the gear 222 is connected to the magnetic body 211, the rack 223 is connected to the output end of the second driver 221, and the rack 223 and the gear 222 are engaged. Among them, the second driver 221 can be a driver for outputting linear motion, such as a cylinder or an electric cylinder. During operation, the second driver 221 drives the rack 223 to move linearly, so that the rack 223 and the gear 222 engage and move, thereby causing the gear 222 to rotate about the first rotation axis L1. In this way, the magnetic body 211 can rotate about the first rotation axis L1 driven by the gear 222, thereby causing the first lock 213 on the magnetic member 21 to lock or unlock relative to the second lock 111. In other implementations, when the magnetic body 211 locks or unlocks the first lock 213 and the second lock 111 by linear movement, the second drive structure 22 can be a linear motor, a pneumatic cylinder, an electric cylinder, a combination mechanism formed by a rotary motor and a screw mechanism, etc.

[0187] By adopting the above technical solution, the second driving structure 22 is used to drive the locking or unlocking between the first lock buckle 213 and the second lock buckle 111, so that the automation level of the iron removal device 100 can be improved, thereby improving the working efficiency of the iron removal device 100.

[0188] It should be noted here that the second drive structure 22 can also be electrically connected to the above-mentioned control device, so that the second drive structure 22 can be controlled by sending control instructions through the control device, so that the second drive structure 22 drives the first lock 213 and the second lock 111 to lock or unlock, with a high degree of automation.

[0189] In some embodiments, please refer to Figures 15 to 18. Figure 15 shows a partial schematic diagram of the iron removal device 100 when the receiving tray 60 is in the first position below, Figure 16 is a partial enlarged view of Figure 15, and Figure 17 shows a partial schematic diagram of the iron removal device 100 when the receiving tray 60 is in the second position below, and Figure 18 is a partial enlarged view of Figure 17. The iron removal chamber 11 has a first opening 1101 for the magnetic member 21 to enter and exit, and the cleaning chamber 12 has a second opening 1201 for the magnetic member 21 to enter and exit. Among them, the first opening 1101 and the second opening 1201 described in this embodiment are the same as the first opening 1101 and the second opening 1201 involved in the above embodiments, and will not be repeated here. The iron removal mechanism 20 also includes a third drive structure 23, and the iron removal device 100 also includes a fourth drive structure 30. The third drive structure 23 is used to drive the magnetic member 21 to move, so as to drive the magnetic member 21 to move between one side of the first opening 1101 and the other side of the second opening 1201. The fourth driving structure 30 is used to drive the magnetic element 21 to enter and exit the iron removal chamber 11 or the cleaning chamber 12 .

[0190] It can be understood that the third driving structure 23 is used to drive the magnetic member 21 to move between one side of the first opening 1101 along the first direction Y and one side of the second opening 1201 along the first direction Y. That is, the third driving structure 23 can drive the magnetic member 21 from one side of the first opening 1101 along the first direction Y to one side of the second opening 1201 along the first direction Y, and can also drive the magnetic member 21 from one side of the second opening 1201 along the first direction Y to one side of the first opening 1101 along the first direction Y. The fourth driving structure 30 is used to drive the magnetic member 21 to move along the first direction Y, so that the magnetic member 21 enters and exits the iron removal chamber 11 or enters and exits the cleaning chamber 12.

[0191] Specifically, during the operation of the iron removal device 100, the magnetic component 21 can be first placed on one side of the first opening 1101 along the first direction Y, and the magnetic component 21 can be driven to move along the first direction Y by the fourth driving structure 30, so that the magnetic component 21 extends into the iron removal chamber 11 through the first opening 1101 along the first direction Y. After the magnetic component 21 completes the work of magnetically attracting metal impurities in the iron removal chamber 11, the fourth driving structure 30 drives the magnetic component 21 to move along the first direction Y, so that the magnetic component 21 moves out of the iron removal chamber 11 along the first direction Y and moves to the side of the first opening 1101 along the first direction Y. Subsequently, the third driving structure 23 drives the magnetic component 21 from the side of the first opening 1101 along the first direction Y to the side of the second opening 1201 along the first direction Y. Then, the fourth driving structure 30 drives the magnetic component 21 to move along the first direction Y, so that the magnetic component 21 extends into the cleaning chamber 12 along the first direction Y through the second opening 1201 for cleaning. Afterwards, the fourth driving structure 30 drives the magnetic component 21 to move out of the cleaning chamber 12 along the first direction Y to drive the magnetic component 21 to move to the side of the second opening 1201 along the first direction Y. The third driving structure 23 drives the magnetic component 21 from the side of the second opening 1201 along the first direction Y to the side of the first opening 1101 along the first direction Y. The fourth driving structure 30 drives the magnetic component 21 to move along the first direction Y so that the magnetic component 21 extends into the iron removal chamber 11 along the first direction Y to magnetically attract metal impurities... and so on. The third driving structure 23 and the fourth driving structure 30 work alternately to realize the movement of the magnetic component 21 between the iron removal chamber 11 and the cleaning chamber 12.

[0192] It can be understood that the fourth driving structure 30 is used to drive the magnetic part 21 to move along the first direction Y, that is, to drive the magnetic part 21 to move linearly. The fourth driving structure 30 can be a component or assembly for outputting linear driving force, such as a cylinder, an electric cylinder, a combined mechanism formed by a rotating motor and a screw mechanism.

[0193] In some implementations, the third drive structure 23 is used to drive the magnetic member 21 to rotate around the second rotation axis L2, as shown in Figure 2, thereby driving the magnetic member 21 between one side of the first opening 1101 along the first direction Y and one side of the second opening 1201 along the first direction Y. At this time, the third drive structure 23 can be a component or assembly such as a rotating motor, a combined mechanism formed by a rotating motor and a transmission member, or a combined mechanism formed by a rotating motor and a reducer. Among them, the second rotation axis L2 is parallel to the first direction Y and also parallel to the first rotation axis L1. Exemplarily, as shown in Figures 2 and 14, the iron removal mechanism 20 also includes a mounting seat 24, which is connected to the output end of the third drive structure 23 and can rotate around the second rotation axis L2 under the drive of the third drive structure 23. The magnetic member 21 is connected to the output end of the second drive structure 22, and the second drive structure 22 is arranged on the mounting seat 24, and can rotate around the second rotation axis L2 together with the mounting seat 24 under the drive of the third drive structure 23. In other implementations, the third driving structure 23 is used to drive the magnetic member 21 to move linearly, so as to drive the magnetic member 21 between one side of the first opening 1101 along the first direction Y and one side of the second opening 1201 along the first direction Y. In this case, the third driving structure 23 can be a component or assembly for outputting a linear driving force, such as a linear motor, an electric cylinder, or a pneumatic cylinder.

[0194] By adopting the above-mentioned technical solution, the third driving structure 23 and the fourth driving structure 30 can alternately drive the magnetic component 21 to move, thereby realizing the effect of the magnetic component 21 moving between the iron removal chamber 11 and the cleaning chamber 12, and the movement of the magnetic component 21 can be made more automated, that is, the automation performance of the iron removal device 100 is improved, which helps to improve the working efficiency of the iron removal device 100.

[0195] It should be noted that both the third driving structure 23 and the fourth driving structure 30 can be electrically connected to the control device to drive the magnetic element 21 under the control of the control device, thereby realizing automatic movement of the magnetic element 21.

[0196] As described above, the iron removal device 100 provided in the embodiment of the present application can automatically realize the magnetic attraction of the metal impurities in the slurry by the magnetic attraction component 21 in the iron removal chamber 11, and can also automatically realize the cleaning of the magnetic attraction component 21 in the cleaning chamber 12, so that the iron removal device 100 has higher automation performance, which helps to improve the working efficiency of the iron removal device 100.

[0197] In some embodiments, please refer to Figures 15 and 16 together. The iron removal device 100 also includes a receiving tray 60. The receiving tray 60 can be located on one side of the first opening 1101 and one side of the second opening 1201 at the same time to receive the slurry or metal impurities flowing out of the magnetic element 21.

[0198] Specifically, when the magnetic member 21 moves out of the iron removal chamber 11 to be located on one side of the first opening 1101 along the first direction Y, or when the magnetic member 21 moves out of the cleaning chamber 12 to be located on one side of the second opening 1201 along the first direction Y, the receiving tray 60 can be located on one side of the first opening 1101 along the first direction Y and on one side of the second opening 1201 along the first direction Y. In addition, the receiving tray 60 is also located between the iron removal chamber 11 and the magnetic member 21 along the first direction Y, and is also located between the cleaning chamber 12 and the magnetic member 21 along the first direction Y. For example, as shown in Figures 15 and 16, the first direction Y is parallel to the up and down directions shown in the figures. At this time, the magnetic member 21 is located above the cleaning chamber 12, that is, on one side of the second opening 1201 along the first direction Y. In addition, the receiving tray 60 is located below the magnetic member 21 and above the first opening 1101 and the second opening 1201. In this way, when the slurry and / or metal impurities on the magnetic component 21 flow down, the receiving tray 60 can receive the slurry and / or metal impurities. When the magnetic component 21 moves between one side of the first opening 1101 and one side of the second opening 1201, if the slurry and / or metal impurities on the magnetic component 21 are thrown out under the eccentricity, they can also be received by the receiving tray 60.

[0199] Therefore, by adopting the above-mentioned technical solution, the receiving plate 60 can receive the slurry and / or metal impurities on the magnetic component 21 when the magnetic component 21 is moved out of the iron removal chamber 11 and the cleaning chamber 12. This can improve the problem of the slurry and / or metal impurities on the magnetic component 21 being thrown out of the iron removal device 100, thereby maintaining the cleanliness of the iron removal device 100 during operation.

[0200] In some embodiments, please refer to Figures 15 to 18 together. The receiving tray 60 can move between a first position and a second position. When the receiving tray 60 is in the first position, it is used to receive slurry and / or metal impurities. When the receiving tray 60 is in the second position, it can allow the magnetic suction component 21 to enter and exit the iron removal chamber 11 or the cleaning chamber 12.

[0201] After the magnetic element 21 is simultaneously moved out of the iron removal chamber 11 and the cleaning chamber 12, the receiving tray 60 can move to the first position, as shown in Figures 15 and 16. At this time, the receiving tray 60 is simultaneously located on one side of the first opening 1101 along the first direction Y and on one side of the second opening 1201 along the first direction Y, and the receiving tray 60 is also simultaneously located at a position between the iron removal chamber 11 and the magnetic element 21 along the first direction Y and a position between the cleaning chamber 12 and the magnetic element 21 along the first direction Y. In addition, one side of the receiving tray 60 along the first direction Y is simultaneously opposite to the first opening 1101 and the second opening 1201, and the other side of the receiving tray 60 along the first direction Y is opposite to the magnetic element 21. In this way, the receiving tray 60 can be used to receive slurry and / or metal impurities flowing out of the magnetic element 21. It should be noted that at this time, the receiving tray 60 blocks the first opening 1101 and the second opening 1201, as shown in Figures 15 and 16, making it difficult for the magnetic element 21 to extend into the iron removal chamber 11 or the cleaning chamber 12. It is understood that the first position refers to a position on one side of the first opening 1101 along the first direction Y and a position on one side of the second opening 1201 along the first direction Y, and directly opposite the first opening 1101 and the second opening 1201.

[0202] When the receiving tray 60 moves to the second position, as shown in Figures 17 and 18, the receiving tray 60 avoids the first opening 1101 and the second opening 1201, and the magnetic element 21 can smoothly enter and exit the iron removal chamber 11 or the cleaning chamber 12. For example, in some embodiments, as shown in Figure 18, the receiving tray 60 can also be located on one side of the first opening 1101 along the first direction Y and on one side of the second opening 1201 along the first direction Y, but the receiving tray 60 is not directly opposite the first opening 1101 and the second opening 1201 along the first direction Y, that is, the receiving tray 60 avoids the first opening 1101 and the second opening 1201. In other embodiments, the receiving tray 60 may not be located on one side of the first opening 1101 along the first direction Y and on one side of the second opening 1201 along the first direction Y.

[0203] By adopting the above-mentioned technical solution, the receiving tray 60 can move between a first position and a second position. Specifically, the receiving tray 60 can move to the first position after the magnetic element 21 is removed from the iron removal chamber 11 or the cleaning chamber 12, so as to receive the slurry and / or metal impurities flowing out of the magnetic element 21. The receiving tray 60 can also move to the second position when the magnetic element 21 needs to be extended into the iron removal chamber 11 or the cleaning chamber 12, so as to avoid the first opening 1101 and the second opening 1201, so as to facilitate the magnetic element 21 to extend into the iron removal chamber 11 or the cleaning chamber 12. With such a configuration, the slurry or metal impurities flowing out of the magnetic element 21 can be better received during the movement of the magnetic element 21, and the problem of the receiving tray 60 interfering with the movement of the magnetic element 21 can also be improved.

[0204] In some embodiments, please refer to Figures 15 to 18 together. The iron removal device 100 also includes a slide rail 70. The receiving tray 60 can slide along the slide rail 70 to switch between the first position and the second position, thereby improving the movement flexibility and efficiency of the receiving tray 60.

[0205] In some embodiments, please refer to Figures 2, 3 and 14 together. The cleaning mechanism 10 includes a plurality of iron removal chambers 11 and a plurality of cleaning chambers 12, and each iron removal chamber 11 and each cleaning chamber 12 are alternately distributed along the circumferential direction. The iron removal mechanism 20 includes a plurality of magnetic members 21, and the plurality of magnetic members 21 are spaced apart along the circumferential direction. Moreover, each magnetic member 21 can rotate around the second rotation axis L2 to rotate alternately to the side of the corresponding iron removal chamber 11 along the first direction Y and the side of the corresponding cleaning chamber 12 along the first direction Y. The magnetic member 21 can enter and exit the iron removal chamber 11 along the first direction Y, and can also enter and exit the cleaning chamber 12 along the first direction Y. Among them, the second rotation axis L2 is parallel to the first direction Y, and is parallel to the direction in which the magnetic member 21 enters and exits the iron removal chamber 11, and the direction in which the magnetic member 21 enters and exits the cleaning chamber 12.

[0206] The second rotation axis L2 mentioned here is the same as the second rotation axis L2 involved in the above embodiments.

[0207] Among them, the circumferential directions in "each iron removal chamber 11 and each cleaning chamber 12 are alternately distributed along the circumferential direction" and "a plurality of magnetic suction parts 21 are spaced apart along the circumferential direction" are both perpendicular to the second rotation axis L2 and perpendicular to the first direction Y.

[0208] The number of iron removal chambers 11 is the same as the number of cleaning chambers 12. The number of magnetic elements 21 is the same as the number of iron removal chambers 11, and multiple magnetic elements 21 are provided in a one-to-one correspondence with multiple iron removal chambers 11. Correspondingly, the number of cleaning chambers 12 is also the same as the number of magnetic elements 21, and multiple magnetic elements 21 are provided in a one-to-one correspondence with multiple cleaning chambers 12.

[0209] By adopting the above technical solution, multiple magnetic members 21 can be extended into multiple iron removal chambers 11 in a one-to-one correspondence, so that multiple magnetic members 21 can magnetically attract metal impurities in the corresponding iron removal chambers 11. After the magnetic members 21 complete the magnetic attraction of metal impurities, the multiple magnetic members 21 can be removed from the multiple iron removal chambers 11 in a one-to-one correspondence, and extended into the multiple cleaning chambers 12 in a one-to-one correspondence, thereby achieving the cleaning of the magnetic members 21. In this way, the setting of multiple cleaning chambers 12, multiple iron removal chambers 11 and multiple magnetic members 21 enables the iron removal device 100 to complete the metal impurity removal work of the slurry in multiple iron removal chambers 11 at one time, and can also complete the cleaning work of multiple magnetic members 21 at one time, thereby improving the working efficiency of the iron removal device 100.

[0210] In some embodiments, please refer to Figures 1, 2, 4, 19 and 20 together, and in combination with other drawings, Figure 19 shows a three-dimensional schematic diagram of the iron removal device 100 provided in some embodiments of the present application at another perspective, and Figure 20 shows a partial enlarged view of Figure 19. The iron removal chamber 11 has a first feed port 1102 and a second feed port 1103, any one of the first feed port 1102 and the second feed port 1103 is used for the slurry to enter, and the other is used for the slurry to flow out. The cleaning mechanism 10 also includes a first conduit 15 and a second conduit 16, and the first feed ports 1102 of the plurality of iron removal chambers 11 are connected to the first conduit 15, and the second feed ports 1103 of the plurality of iron removal chambers 11 are connected to the second conduit 16.

[0211] It can be understood that the first confluence pipe 15 is connected to the inner cavity of multiple iron removal chambers 11 through the first feed port 1102, and the second confluence pipe 16 is connected to the inner cavity of multiple iron removal chambers 11 through the second feed port 1103. Based on this, when the first feed port 1102 is the inlet of the slurry, the external slurry can first enter the first confluence pipe 15, and then enter the corresponding iron removal chamber 11 through the first feed port 1102 of the multiple iron removal chambers 11 respectively. After the magnetic suction component 21 completes the removal of metal impurities from the slurry in the iron removal chamber 11, the slurry in each iron removal chamber 11 flows out to the second confluence pipe 16 through the corresponding second feed port 1103, and finally flows out to the designated position. Conversely, when the second feed port 1103 is the outlet of the slurry, the external slurry can first enter the second confluence pipe 16, and then enter the corresponding iron removal chamber 11 through the second feed port 1103 of the multiple iron removal chambers 11 respectively. After the magnetic element 21 completes the removal of metal impurities from the slurry in the iron removal chamber 11 , the slurry in each iron removal chamber 11 flows out through the corresponding first feed port 1102 into the first conduit 15 and finally flows out to a designated location.

[0212] It is understood that the slurry first converges in the first conduit 15 and then flows into the multiple iron removal chambers 11 separately. After the slurry in the iron removal chamber 11 completes the removal of metal impurities, the slurries in the multiple iron removal chambers 11 first converge in the second conduit 16 and then flow out to the designated location. Conversely, the slurry may also first converge in the second conduit 16 and then flow into the multiple iron removal chambers 11 separately. After the slurry in the iron removal chamber 11 completes the removal of metal impurities, the slurries in the multiple iron removal chambers 11 first converge in the first conduit 15 and then flow out to the designated location.

[0213] By adopting the above technical solution, the slurry in the multiple iron removal chambers 11 is converged through the first converging pipe 15 and the second converging pipe 16, without the need for each iron removal chamber 11 to be connected to an external device for inputting and outputting slurry through its own pipe. This simplifies the pipe design for the slurry circulation in the iron removal chamber 11, thereby simplifying the iron removal device 100. In addition, the converging effect of the first converging pipe 15 and the second converging pipe 16 allows the slurry to quickly enter the multiple iron removal chambers 11, and the slurry in the multiple iron removal chambers 11 can also quickly flow out, thereby helping to improve the metal impurity removal effect of the slurry.

[0214] In some embodiments, please refer to FIG. 19 and FIG. 20 , the first confluence pipe 15 is annular and is disposed around the plurality of iron removal chambers 11 and cleaning chambers 12 .

[0215] By adopting the above technical solution, the first confluence pipe 15 is arranged in a ring around multiple cleaning chambers 12 and multiple iron removal chambers 11, so that the first confluence pipe 15, the second confluence pipe 16, the cleaning chamber 12, the iron removal chamber 11, etc. can be made more compact, thereby improving the structural compactness of the iron removal device 100 and realizing a miniaturized design of the iron removal device 100.

[0216] In some embodiments, please refer to FIG. 1 and FIG. 2 , the iron removal device 100 further includes a pressure relief pipe 50 , which is connected to the iron removal chamber 11 and is used for pressure relief.

[0217] The pressure relief pipe 50 may be a single pipe or may be formed by connecting a plurality of pipes in sequence.

[0218] It is understood that the pressure relief pipe 50 is connected to the iron removal chamber 11 and communicates with the inner cavity of the iron removal chamber 11, and the pressure relief pipe 50 can also communicate with the external environment. In this way, the gas in the iron removal chamber 11 can be discharged to the external environment through the pressure relief pipe 50, thereby reducing the pressure difference between the inner cavity of the iron removal chamber 11 and the external environment.

[0219] By adopting the above technical solution, the pressure relief pipe 50 can achieve a pressure relief effect on the iron removal chamber 11, so that the pressure difference between the iron removal chamber 11 and the external environment is not large, which is conducive to the flexible flow of slurry in the iron removal chamber 11, thereby facilitating the magnetic attraction of the magnetic element 21 to magnetically attract the metal impurities in the slurry in the iron removal chamber 11. Based on this, the problem that the slurry is difficult to flow due to excessive pressure in the iron removal chamber 11, and the magnetic attraction of the magnetic element 21 cannot smoothly perform the magnetic attraction of the metal impurities, can be improved.

[0220] It should be noted that when the cleaning mechanism 10 includes multiple iron removal chambers 11, each iron removal chamber 11 can be connected to a separate pressure relief pipe 50 for independent pressure relief. Of course, the pressure relief pipe 50 can also be connected to multiple iron removal chambers 11 simultaneously to relieve pressure in multiple iron removal chambers 11 simultaneously, thereby simplifying the arrangement of the pressure relief pipe 50 within the iron removal device 100 and simplifying the structure of the iron removal device 100.

[0221] In some embodiments, please refer to FIG. 1 and FIG. 2 , there are multiple cleaning mechanisms 10 , and the iron removal chambers 11 of the multiple cleaning mechanisms 10 are connected in sequence.

[0222] It can be understood that when the slurry is passed into the iron removal device 100, the slurry can first pass into the iron removal chamber 11 of the first cleaning mechanism 10, and pass through the magnetic attraction of the metal impurities of the magnetic attraction part 21, and then pass into the iron removal chamber 11 of the second cleaning mechanism 10, and pass through the magnetic attraction of the metal impurities of the magnetic attraction part 21... and so on, the slurry finally passes through the iron removal chamber 11 of the last cleaning mechanism 10, and passes through the magnetic attraction of the metal impurities of the magnetic attraction part 21, and then flows out of the iron removal device 100.

[0223] By adopting the above technical solution, the slurry can be sequentially passed into the iron removal chambers 11 of multiple cleaning mechanisms 10 to sequentially remove metal impurities through the magnetic elements 21, thereby improving the metal impurity removal effect of the slurry.

[0224] In some embodiments, the number of the iron removal mechanisms 20 may also be multiple, and the multiple cleaning mechanisms 10 and the multiple iron removal mechanisms 20 are provided in a one-to-one correspondence, and the magnetic attraction member 21 of each iron removal mechanism 20 is used to magnetically attract the metal impurities in the iron removal chamber 11 of each cleaning mechanism 10. In this manner, the magnetic attraction members 21 of the multiple iron removal mechanisms 20 can correspond to the metal impurities in the iron removal chambers 11 of the multiple cleaning mechanisms 10, thereby improving the cleaning efficiency of the slurry.

[0225] It should be noted that if there are multiple iron removal mechanisms 20, there will also be multiple third drive structures 23, and the third drive structure 23 of each iron removal mechanism 20 is used to drive the magnetic member 21 of the corresponding iron removal mechanism 20. Furthermore, the fourth drive structure 30 can simultaneously drive the second drive structures 22, third drive structures 23, and magnetic members 21 of multiple iron removal mechanisms 20 to move along the first direction Y.

[0226] Please refer to Figures 1, 2 and 21 , which shows a schematic diagram of the coordination between the slurry production equipment 200 and the iron removal device 100 . A second aspect of the present application provides a slurry production system, which includes the iron removal device 100 .

[0227] It is understandable that the slurry production system also includes a slurry production device 200, which is used to produce output slurry. The iron removal chamber 11 of the iron removal device 100 is connected to the second feed port 1103 of the slurry production device 200. Based on this, during the operation of the slurry production system, the slurry production device 200 produces output slurry and transports the slurry to the iron removal chamber 11 of the iron removal device 100. The magnetic suction component 21 of the iron removal device 100 magnetically attracts the metal impurities in the slurry passed into the iron removal chamber 11 to clean the slurry and transport the slurry from the iron removal chamber 11 to a preset station. For example, in some embodiments, when the slurry of the slurry production system is used to make battery pole pieces, the preset station can be a station for making pole pieces.

[0228] By adopting the above technical solution, since the iron removal device 100 involved in the above embodiments is adopted, there is no need to replace the magnetic part 21 after the magnetic part 21 has attracted more metal impurities. The magnetic part 21 can be inserted into the iron removal chamber 11 again to magnetically attract metal impurities with better magnetic attraction, which reduces the replacement of the magnetic part 21. In addition, there is no need for excessive manual intervention in the magnetic attraction work and cleaning work of the magnetic part 21, which saves manpower. Therefore, the iron removal device 100 has a higher automation performance, thereby improving the working efficiency of the iron removal device 100. Accordingly, the slurry production system has a higher automation performance and a higher working efficiency.

[0229] Please refer to Figures 1, 2, and 22. Figure 22 shows a flow chart of the metal impurity removal method. A third aspect of the present application provides a metal impurity removal method, which is applied to the iron removal device 100 involved in each of the above embodiments. The metal impurity removal method includes the following steps:

[0230] S10, driving the magnetic element 21 into the iron removal chamber 11, and then introducing the slurry into the iron removal chamber 11;

[0231] In this embodiment, when the slurry is introduced into the iron removal chamber 11 , the magnetic element 21 can magnetically attract metal impurities in the slurry through its magnetic attraction properties, thereby cleaning the slurry in the iron removal chamber 11 .

[0232] S20 , driving the magnetic member 21 from the iron removal chamber 11 into the cleaning chamber 12 to clean the magnetic member 21 .

[0233] In this embodiment, after the magnetic element 21 completes the cleaning of the slurry in the iron removal chamber 11, the magnetic element 21 is removed from the iron removal chamber 11, and then the magnetic element 21 is extended into the cleaning chamber 12 for cleaning. In this way, the magnetic element 21 can continuously maintain a high magnetic attraction ability to continuously magnetically attract metal impurities in the slurry entering the iron removal chamber 11.

[0234] By adopting the above technical solution, the magnetic element 21 can be moved into the iron removal chamber 11 or the cleaning chamber 12, and the magnetic element 21 can alternately realize the magnetic attraction work of the metal impurities or the cleaning work of the magnetic element 21. In this way, there is no need to replace the magnetic element 21 after the magnetic element 21 has attracted more metal impurities, so that the magnetic element 21 can be inserted into the iron removal chamber 11 again to magnetically attract metal impurities with better magnetic attraction ability, which reduces the replacement of the magnetic element 21. In addition, there is no need for excessive manual intervention in the magnetic attraction work and cleaning work of the magnetic element 21, which saves manpower. As a result, the iron removal device 100 has higher automation performance, thereby improving the working efficiency of the iron removal device 100. Accordingly, the method for removing metal impurities can have higher automation performance and working efficiency.

[0235] In some embodiments, referring to FIG. 2 to FIG. 7 , after step S20, the following steps are further included:

[0236] S30 , moving the magnetic element 21 out of the cleaning chamber 12 , and scraping the metal impurities on the magnetic element 21 into the cleaning chamber 12 by the scraping element 13 .

[0237] In this embodiment, the scraper 13 scrapes metal impurities from the magnetic member 21 into the cleaning chamber 12, effectively cleaning the magnetic member 21. This makes cleaning the magnetic member 21 very simple and easy to perform. This helps improve the cleaning efficiency of the magnetic member 21, thereby improving the cleaning efficiency and production capacity of the slurry.

[0238] As one of the embodiments of the present application, the iron removal device 100 includes a plurality of cleaning mechanisms 10 and a plurality of iron removal mechanisms 20, and the plurality of cleaning mechanisms 10 and the plurality of iron removal mechanisms 20 are arranged in a one-to-one correspondence. Each cleaning mechanism 10 includes a plurality of iron removal chambers 11 and a plurality of cleaning chambers 12, and the iron removal chambers 11 and the cleaning chambers 12 of each cleaning mechanism 10 are alternately distributed in sequence along the circumferential direction. Each iron removal mechanism 20 includes a plurality of magnetic members 21, and the plurality of magnetic members 21 of each iron removal mechanism 20 are distributed in sequence along the circumferential direction. In addition, the iron removal chambers 11 of the plurality of cleaning mechanisms 10 are connected in sequence.

[0239] When the iron removal device 100 is working, the multiple magnetic members 21 of each iron removal mechanism 20 extend into the multiple iron removal chambers 11 of the corresponding cleaning mechanism 10 one by one, and the slurry passes through the iron removal chambers 11 of the multiple cleaning mechanisms 10 in turn, and the metal impurities are removed by the multiple iron removal mechanisms 20 in turn. Then, the magnetic member 21 of each iron removal mechanism 20 moves out of the corresponding iron removal chamber 11 and extends into the corresponding cleaning chamber 12 to perform cleaning work. Subsequently, the magnetic member 21 of each iron removal mechanism 20 moves out of the corresponding cleaning chamber 12 and then extends into the corresponding iron removal chamber 11, and the slurry is replaced, thereby achieving the metal impurity removal work of the next batch of slurry.

[0240] The above are merely optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included within the scope of the claims of the present application.
