Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0038] Reference Figure 1 and Figure 2 As shown, Figure 1 This is a perspective view of the iron removal device provided in the embodiments of this application. Figure 2This is a schematic diagram of the internal structure of the iron removal device provided in this embodiment. This embodiment discloses an iron removal device, which includes a housing 1 and at least two iron removers 2. The housing 1 has a receiving cavity 11, which has a feeding area 110 and cleaning areas 111 located on both sides of the feeding area 110. One feeding area 110 and one cleaning area 111 are the same size. Along the length of the housing 1, the length of one feeding area 110 is equal to or greater than the length of one iron remover 2, and the length of one cleaning area 111 is equal to or greater than the length of one iron remover 2, to ensure that one feeding area 110 and one cleaning area 111 can accommodate one iron remover 2. Along the height of the housing 1, the feeding area 110 has an inlet end 110a and an outlet end 110b arranged opposite to each other, and the inlet end 110a and the outlet end 110b communicate with the receiving cavity 11. Each magnetic separator 2 is disposed within the receiving cavity 11 and distributed along the length of the receiving cavity 11. The side walls of the multiple magnetic separators 2 are connected (the connection can be welding or bonding). The multiple magnetic separators 2 are arranged side by side along the length of the outer shell 1. The length of the receiving cavity 11 is greater than the total length of all the magnetic separators 2. The magnetic separators 2 are adapted to move along the length of the receiving cavity 11. The magnetic separators 2 are provided with a feed inlet 21 and a discharge outlet 22. When the magnetic separators 2 are located in the feeding zone 110, the feed inlet 21 at least partially coincides with the feed end 110a, and the discharge outlet 22 at least partially coincides with the discharge end 110b. The length of the outer shell 1 is... Figure 1 In the X direction, the width direction of the outer shell 1 is... Figure 1 In the Y direction, the height direction of shell 1 is... Figure 1 The Z direction in the equation.

[0039] In this embodiment, each iron separator 2 also includes a sealing element (not shown in the figure). The sealing element is disposed at the feed inlet 21. When the iron separator 2 is located in the feeding zone 110, the sealing element of the feed inlet 21 of the iron separator 2 located in the feeding zone 110 abuts against the feed end 110a, thereby reducing the leakage of material from the gap between the feed end 110a and the feed inlet 21, ensuring the sealing between the feed end 110a and the feed inlet 21. The sealing element is made of soft rubber, which has good elasticity and wear resistance, so that when the iron separator 2 moves, the soft rubber can withstand the friction between it and the outer shell 1, reducing the wear and scratches caused by friction to a certain extent, and improving the service life of the sealing element. The discharge port 22 of the iron separator 2 can also be provided with a sealing element to reduce the leakage of material from the gap between the discharge end 110b and the discharge port 22, ensuring the sealing between the discharge end 110b and the discharge port 22.

[0040] In this embodiment, the outer shell 1 is made of stainless steel. Stainless steel has good wear resistance, corrosion resistance and antimagnetic properties, which reduces the adsorption of magnetic substances in the material by the outer shell 1 while ensuring the strength of the outer shell 1, thus ensuring the safe operation of the iron removal device. It is understood that in other embodiments, the outer shell 1 may also be made of other materials with antimagnetic properties, such as plastic.

[0041] This embodiment is provided with at least two iron separators 2, and multiple iron separators 2 are arranged side by side along the X-axis. The iron separators 2 are adapted to move along the length of the receiving cavity 11. During operation, the material entering from the feed end 110a flows into the iron separator 2 through the feed port 21 of the iron separator 2 located in the feeding area 110. After demagnetization, it flows out from the discharge end 110b through the discharge port 22. When the iron separator 2 located in the feeding area 110 moves to the cleaning area 111 for cleaning, another iron separator 2 can move to the feeding area 110 to continue feeding. This reduces the need for the iron separator to stop during cleaning and reduces the situation where the iron separator loses its demagnetization ability during cleaning, resulting in abnormal material flowing into the next step. This ensures the continuity of production and the quality of materials, and improves production efficiency.

[0042] Reference Figures 2-5 As shown, Figure 3 This is a top perspective view of the iron removal device provided in the embodiments of this application. Figure 4 This is a schematic diagram of the structure of the iron removal component of the iron removal device provided in the embodiments of this application. Figure 5 This is a schematic diagram of the iron removal device provided in the embodiments of this application. The iron remover 2 includes a housing 23, an iron removal assembly 24, and a push rod 25. The side walls of two adjacent housings 23 on two adjacent iron removers 2 are connected (by welding or bonding). The housing 23 has a cavity structure, and an inlet 21 and an outlet 22 communicating with the cavity structure are provided on the housing 23. The iron removal assembly 24 includes a magnetic rod sleeve 240, multiple magnetic rods 241, and a mounting plate 242. The magnetic rod sleeve 240 is rotatably connected to the housing 23 and located within the cavity structure, and the magnetic rod sleeve 240 extends along the width direction of the housing 1. The magnetic rod sleeve 240 has multiple mounting slots 240a. Each magnetic rod 241 is detachably installed in each mounting slot 240a, and each magnetic rod 241 is connected to the mounting plate 242, so that the multiple magnetic rods 241 are integrated, thereby facilitating the assembly and disassembly of the magnetic rods 241. The push rod 25 can be connected to the middle of the magnetic rod sleeve 240 or to the outer wall of the housing 23.

[0043] In one embodiment, the outer casing 1 has a sliding guide opening 12 extending along its length. A push rod 25 passes through the sliding guide opening 12 and is connected to the casing 23. The push rod 25 is at least partially located on the outside of the outer casing 1, allowing it to be manually pushed, thereby driving the magnetic separator 2 to slide within the receiving cavity 11. The magnetic separator 2 is equipped with a drive mechanism, and the rotation of the magnetic rod sleeve 240 can be driven by the drive mechanism built into the magnetic separator 2.

[0044] In one embodiment, the push rod 25 is fixedly connected to the magnetic rod sleeve 240, and the push rod 25 can drive the magnetic rod sleeve 240 to rotate. The iron removal device also includes a motor 3 and a transmission assembly 4, the transmission assembly 4 being connected to the push rods 25 on at least two magnetic rod sleeves 240. The motor 3 is connected to the transmission assembly 4 through the sliding guide port 12, the motor 3 is used to drive the transmission assembly 4 to rotate, the transmission assembly 4 is used to drive all the push rods 25 to rotate, and the push rods 25 are used to drive the magnetic rod sleeves 240 to rotate within the housing 23. By using a single motor 3 to drive the transmission assembly 4 to rotate, all the magnetic rod sleeves 240 can be rotated simultaneously, reducing costs.

[0045] It should be noted that the number of magnetic rods 241 can be set as needed and is not limited here.

[0046] In this embodiment, the transmission assembly 4 includes a belt 41 and multiple synchronous pulleys. Each synchronous pulley is connected to a push rod 25. The belt 41 is wound around each synchronous pulley. The drive end of the motor 3 is connected to the synchronous pulley. The motor 3 is used to drive the connected synchronous pulleys to rotate, thereby moving the belt 41. The movement of the belt 41 drives the other synchronous pulleys to rotate, thereby driving each magnetic rod sleeve 240 to rotate. The belt drive can mitigate impact and absorb vibration, making the transmission process smooth, thus ensuring the stability of each iron separator 2 during operation. In addition, the belt 41 is connected to the push rod 25 through the synchronous pulleys, reducing the possibility of slippage caused by the belt 41 being directly connected to the push rod 25, further improving the stability of each iron separator 2 during operation.

[0047] It is understood that in other embodiments, the motor 3 may also be directly connected to any push rod 25 (the drive end of the motor 3 is connected to the push rod 25 via a coupling), and the transmission component 4 may also be other transmission structures, such as gear transmission or chain transmission.

[0048] Reference Figure 2 and Figure 5As shown, there are two magnetic separators 2 connected together, and the distance between the push rods 25 on the two magnetic separators 2 is half the length of the sliding guide 12. Specifically, the sliding guide 12 has a first end 120 and a second end 121. The two magnetic separators 2 are designated as a first magnetic separator 2a and a second magnetic separator 2b. When the second magnetic separator 2b moves to abut against the second end 121, the first magnetic separator 2a is located in the feeding area 110, and the feed inlet 21 of the first magnetic separator 2a is connected to the feed end 110. Alignment: When the first iron separator 2a moves to abut against the first end 120, the second iron separator 2b is located in the feeding area 110, and the feed port 21 of the second iron separator 2b is aligned with the feed end 110a. By making the distance between the push rods 25 on the two iron separators 2 half the length of the sliding guide 12, the iron separator 2 can be limited by the first end 120 and the second end 121 of the sliding guide 12 when the iron separator 2 moves, thus ensuring the accuracy of the movement of the iron separator 2.

[0049] In this embodiment, the two iron separators 2 are connected, so that when one iron separator 2 is pushed, the other iron separator 2 can move together without having to be pushed multiple times, thus improving work efficiency. It is understood that in other embodiments, the two iron separators 2 can also be set separately.

[0050] In specific applications, the number of iron removers 2 can be set as needed, and the number of cleaning zones 111 and feeding zones 110 can be adjusted according to the number of iron removers 2. For example, when there are four iron removers 2, the receiving cavity 11 can be arranged with cleaning zone 111, feeding zone 110, cleaning zone 111, feeding zone 110 and cleaning zone 111 along the length of the outer shell 1, so that materials can be fed simultaneously through two feeding zones 110, further improving production efficiency.

[0051] In this embodiment, the iron separator 2 is a rotary iron separator. The rotary iron separator reduces the blockage caused by material accumulation by rotating continuously, increases the adsorption area of ​​the magnetic rod 241, thereby improving the demagnetization efficiency of the iron separator 2. In addition, the self-rotation during the cleaning process also satisfies the self-cleaning function, which improves the cleaning efficiency of the iron separator 2. It can be understood that in other embodiments, the iron separator 2 may also be of other types, which are not limited here.

[0052] Reference Figure 3 and Figure 5As shown, the iron removal device also includes a slide rail 5 and a slider. The slide rail 5 is disposed in the guide port 12. The slider is slidably connected to the slide rail 5, and the slider has a through hole. The motor 3 includes a motor base and a drive shaft rotatably connected to the motor base. The motor base is fixedly connected to the slider. The drive shaft (i.e., the drive end of the motor 3) passes through the through hole and is connected to the transmission assembly 4. In this embodiment, the sliding connection between the slider and the slide rail 5 ensures the stability and reliability of the iron remover 2 during movement. The motor base extends at least partially through the guide port 12, so that the motor 3 can be pushed from outside the housing 1, thereby driving the iron remover 2 to move between the feeding zone 110 and the cleaning zone 111.

[0053] It should be noted that the iron separator 2 can be moved by manually pushing the motor 3 extending from the sliding guide 12, or it can be moved automatically by a mechanical device by pushing the motor 3 extending from the sliding guide 12. This is not limited here.

[0054] In this embodiment, the iron removal device also includes a pulley 6, which is connected to the bottom of the housing 23 to reduce the friction between the iron remover 2 and the housing 1 when it moves, thereby facilitating the movement of the iron remover 2. The pulley 6 is made of plastic, which has good wear resistance, thereby improving the service life of the pulley 6.

[0055] Reference Figure 2 As shown, the iron removal device also includes a partition (not shown in the figure). The partition is disposed between two adjacent housings 23, and the height of the partition corresponds to the height of the iron remover 2, so as to reduce the cross-contamination between the iron removers 2, thereby ensuring the production efficiency and quality of the iron removal device.

[0056] The iron separator 2 includes a first top wall and a second top wall, located on opposite sides of the feed inlet 21. The first top wall is located on the side of the feed inlet 21 furthest from the partition, and the second top wall is located on the side of the feed inlet 21 closest to the partition. The first and second top walls are set at a predetermined angle. In one embodiment, the second top wall is arranged horizontally (i.e., parallel to the plane formed by the intersection of the X and Y axes), and the angle between the first and second top walls is between 5° and 60°, specifically 5°, 10°, 15°, 30°, 45°, 50°, or 60°. The second top wall is flush with the partition, and the first top wall is lower than the partition. That is, the heights of the first and second top walls on both sides of the iron separator 2 are asymmetrically arranged, thereby reducing material accumulation and ensuring the normal operation of the iron removal device.

[0057] Reference Figure 5 and Figure 6 As shown, Figure 6This is a schematic diagram of the iron removal device provided in another embodiment of this application. The cleaning zone 111 has a magnetic rod extraction port 111a, a magnetic slag collection port 111b, and a cleaning port 111c. The iron removal device also includes a door panel 7, a collection assembly, and a cover plate 8. When the iron remover 2 is located in the cleaning zone 111, the iron removal assembly 24 of the iron remover 2 in the cleaning zone 111 is aligned with the magnetic rod extraction port 111a, so that the magnetic rod 241 can be installed in the magnetic rod sleeve 240 and pulled out of the magnetic rod sleeve 240 through the magnetic rod extraction port 111a. The door panel 7 is movably connected to the outer casing 1, and the door panel 7 covers the magnetic rod extraction port 111a to reduce the entry of dust and other impurities into the receiving cavity 11 from the magnetic rod extraction port 111a, thereby ensuring the normal operation of the iron removal device. The magnetic slag collection port 111b is located at the end of the cleaning zone 111 near the discharge end 110b. When the iron separator 2 is located in the cleaning zone 111, the discharge port 22 of the iron separator 2 in the cleaning zone 111 is aligned with the magnetic slag collection port 111b, and the magnetic slag inside the cavity of the iron separator 2 flows out from the magnetic slag collection port 111b through the discharge port 22. The collection component is set below the magnetic slag collection port 111b to recover the magnetic slag flowing out from the magnetic slag collection port 111b, thereby reducing environmental pollution and improving resource utilization. The cleaning port 111c is set opposite to the magnetic slag collection port 111b. When the iron separator 2 is located in the cleaning zone 111, the feed port 21 of the iron separator 2 in the cleaning zone 111 is aligned with the cleaning port 111c. Through the cleaning port 111c, tools can be used manually to clean the magnetic material on the magnetic rod sleeve 240 inside the iron separator 2, thereby improving the demagnetization efficiency of the iron separator 2. The cover plate 8 is movably connected to the outer casing 1 and covers the cleaning port 111c to reduce the entry of dust and other impurities into the receiving cavity 11 and the cavity body from the cleaning port 111c, thereby ensuring the normal operation of the iron removal device.

[0058] In a specific application scenario, during operation, the second iron separator 2b is first moved to abut against the second end 121, so that the first iron separator 2a is located in the feeding area 110 and the feed port 21 of the first iron separator 2a is aligned with the feed end 110a. Then, the motor 3 is turned on to drive the magnetic rod sleeve 240 to rotate slowly. Then, the material enters the first iron separator 2a from the feed end 110a through the feed port 21. The magnetic substances in the material are attracted to the magnetic rod sleeve 240 by the magnetic rod 241. Normal material flows out from the discharge end 110b through the discharge port 22.

[0059] When the first iron separator 2a needs to be cleaned, it is moved to abut against the first end 120, so that the second iron separator 2b is located in the feeding area 110 and the feed port 21 of the second iron separator 2b is aligned with the feed end 110a. Then, the magnetic rod 241 is pulled out from the magnetic rod sleeve 240 through the magnetic rod pull-out port 111a. After the magnetic rod sleeve 240 loses its magnetism, the magnetic material attached to the magnetic rod sleeve 240 falls off under the action of gravity and rotation and flows out from the magnetic slag collection port 111b to the collection assembly. The cleaning process of the second iron separator 2b is the same as that of the first iron separator 2a, and will not be described in detail here.

[0060] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
