Description

Technical Field

[0001] The invention relates to an iron removal device, in particular to an iron removal machine with a reversible iron removal rod. Background Art

[0002] At present, iron removers are widely used in the field of industrial production and are indispensable products in many production links of the industry. The working method of the iron removers currently used in the field of industrial production is: the magnetic component is placed in a mixture with metal or magnetic substances, and after the magnetic component absorbs the metal or magnetic impurities, the magnetic component is separated from the mixture, and after cleaning, the magnetic component is placed in a mixture with metal or magnetic substances again, and the above iron removal process is carried out again.

[0003] The disadvantage of the working method of the currently used iron remover is that after the magnetic components absorb metal or magnetic impurities, they must leave the mixture and be cleaned before they can be placed back in the mixture for iron removal again. During the cleaning period, the group of magnetic components cannot absorb metal or magnetic impurities, which results in one or more groups of magnetic components failing to achieve the iron removal function during the use of the iron remover, which wastes the resource configuration of the iron remover itself to a certain extent and reduces the iron removal efficiency. Summary of the invention

[0004] The object of the present invention is to provide an iron remover with a reversible iron removal rod, so as to overcome the problem that the magnetic component cannot adsorb impurities during cleaning.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A deironing machine with a reversible deironing rod comprises a container, wherein a deironing rod group is arranged in the container, which can remove iron in the container and can be raised and lowered to be separated from the container. In particular, a scraper is arranged on the deironing rod group, which can be raised and lowered synchronously with the deironing rod group and is used to clean the surface of the deironing rod group, and a first mounting surface and a second mounting surface are formed on the scraper that are relatively arranged along the lifting direction of the scraper; the deironing machine also comprises a reversing device and a pressing device; the reversing device is provided with a reversing motion part that can realize the reversal of the position of the first mounting surface and the second mounting surface, the reversing motion part is connected to the scraper and drives the scraper and the deironing rod group to be reversed synchronously; the pressing device is provided with a pressing motion part that can force the deironing rod group to move to one side of the container through the scraper; after the pressing motion part is pressed down to be connected to the end of the deironing rod group, the pressing motion part continues to press down to the first mounting surface or the second mounting surface, so that a sealed space is formed between the pressing motion part and the scraper; a cleaning component for flushing the deironing rod group and a drain outlet connected to the outside are provided in the sealed space.

[0007] The synchronous lifting of the scraper and the iron removal rod group means that when the iron removal rod group is separated from the container, the scraper can move in the same direction as the iron removal rod group.

[0008] The above-mentioned flipping of the positions of the first mounting surface and the second mounting surface means that when the first mounting surface of the scraper is located at the top and the second mounting surface is located at the bottom, the first mounting surface can be flipped to the bottom and the second mounting surface can be flipped to the top through the flipping device, or when the first mounting surface of the scraper is located at the bottom and the second mounting surface is located at the top, the first mounting surface can be flipped to the top and the second mounting surface can be flipped to the bottom through the flipping device.

[0009] The principle of the above technical solution is:

[0010] The container of the iron remover can be composed of a single slurry conveying line or a plurality of slurry conveying lines.

[0011] When the container is composed of a single slurry conveying line, the iron removal rod group can be cleaned by flipping in situ: after the iron removal machine starts working, a mixture containing impurities such as metal or magnetic impurities flows into the container, and the iron removal rod group is in the container and starts iron removal work, adsorbing the iron powder in the mixture to its own surface. At this time, the scraper is above the mixture, which can be outside or inside the container, with the first bearing surface of the scraper facing the mixture in the container, and the second bearing surface of the scraper facing the pressing device. After the iron removal machine has been working for a period of time, after a certain amount of metal or magnetic impurities are adsorbed on the surface of the iron removal rod group, the iron removal rod group and the scraper rise synchronously relative to the container and detach from the container, and then the flipping device is activated, so that the flipping motion part drives the scraper and the iron removal rod group to flip, so that the first bearing surface of the scraper faces the pressing device, and the second bearing surface of the scraper faces the mixture in the container. At this time, the part of the iron removal rod group that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will also flip to face the pressing device, and the part of the iron removal rod group that is not immersed in the mixture and has a clean surface will flip to face the mixture in the container.

[0012] Subsequently, the pressing device is activated, so that the pressing motion part is pressed down to connect with the iron removal rod group, and continues to press down until the pressing motion part is pressed against the first mounting surface. At this time, the scraper is fixed in position by the flip motion part, and a sealed space is formed between the pressing motion part and the scraper. At the same time, the part of the iron removal rod group that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will be forced to be pressed down by the pressing motion part, so that the part moves from the first mounting surface of the scraper to the second mounting surface of the scraper, and in this process, the metal or magnetic impurities on the surface are scraped off by the scraper. The scraped metal or magnetic impurities will be carried by the first bearing surface and sealed in the sealed space. Subsequently, the iron removal rod group and the scraper synchronously descend relative to the container and return to the container. The part of the iron removal rod group on the second mounting surface of the scraper will be immersed in the mixture again, and the iron removal work will continue. The cleaning component in the sealed space flushes the entire sealed space with water flow, so that the metal or magnetic impurities in the sealed space are discharged from the drain. At this point, the iron removal machine completes an iron removal cleaning cycle. In the next iron removal cleaning cycle, the downward pressing moving part will be pressed against the second bearing surface and form a sealed space with the scraper. The metal or magnetic impurities scraped off in the iron removal cleaning cycle will be carried by the second bearing surface.

[0013] When the container is composed of multiple slurry conveying lines, the iron removal rod group can be cleaned by flipping between the multiple slurry conveying lines: after the iron removal machine starts working, the mixture containing impurities such as metal or magnetic impurities flows into the container, and the iron removal rod group is in the container and starts to remove iron, absorbing the iron powder in the mixture to its own surface. At this time, the scraper is above the mixture, which can be outside or inside the container, with the first bearing surface of the scraper facing the mixture in the container and the second bearing surface of the scraper facing the pressing device. After the iron remover has been working for a period of time, when a certain amount of metal or magnetic impurities are adsorbed on the surface of the iron removal rod group of any slurry conveying line, the iron removal rod group and the scraper rise synchronously relative to the container and detach from the container. Subsequently, the flipping device is activated to cause the flipping motion part to drive the scraper and the iron removal rod group to flip, so that the scraper and the iron removal rod group are flipped to another slurry conveying line. At this time, the first supporting surface of the scraper faces the downward pressure device, and the second supporting surface of the scraper faces the mixture in the container. At this time, the part of the iron removal rod group that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will also flip to face the downward pressure device, while the part of the iron removal rod group that is not immersed in the mixture and has a clean surface will flip to face the mixture in the container.

[0014] Subsequently, the pressing device is activated, so that the pressing motion part is pressed down to connect with the iron removal rod group, and continues to press down until the pressing motion part is pressed against the first supporting surface. At this time, the scraper is fixed in position by the flipping motion part, and a sealed space is formed between the pressing motion part and the scraper. At the same time, the part of the iron removal rod group that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will be forced to be pressed down by the pressing motion part, so that the part moves from the first supporting surface of the scraper to the second supporting surface of the scraper, and in this process, the metal or magnetic impurities on the surface are scraped off by the scraper. The scraped metal or magnetic impurities will be carried by the first bearing surface and sealed in the sealed space. At the same time, the iron removal rod group is pressed back into the container by the pressing device, and the part of the iron removal rod group on the second supporting surface of the scraper will be immersed in the mixture again to continue the iron removal work, while the cleaning component in the sealed space flushes the entire sealed space with water flow, so that the metal or magnetic impurities in the sealed space are discharged from the drain. At this point, the iron removal machine completes an iron removal cleaning cycle. In the next iron removal cleaning cycle, the downward pressing moving part will be pressed against the second bearing surface and form a sealed space with the scraper. The metal or magnetic impurities scraped off in the iron removal cleaning cycle will be carried by the second bearing surface.

[0015] In the above-mentioned iron removal process, the downward pressing moving part will be pressed onto the first supporting surface or the second supporting surface, thereby forming a sealed space with the first supporting surface or the second supporting surface. In the process of the downward pressing moving part pressing down to the end of the iron removal rod group, one of the first supporting surface or the second supporting surface will always be arranged toward the downward pressing device, and the other supporting surface will be arranged toward the mixture in the container. Therefore, when the first supporting surface is arranged toward the downward pressing device, the downward pressing moving part will be pressed onto the first supporting surface; when the second supporting surface is arranged toward the downward pressing device, the downward pressing moving part will be pressed onto the second supporting surface.

[0016] When the iron removal rod group of the iron removal machine needs to be cleaned, the iron removal rod group only needs to be separated from the container, and after a flipping action, it can be returned to the container to complete the iron removal work. This undoubtedly greatly shortens the non-iron removal time of the iron removal rod group. While maintaining the original number of iron removal rod groups in the iron removal machine, the iron removal efficiency of the iron removal machine can be greatly improved.

[0017] Since there are generally multiple groups of iron removal rod groups in the container of the iron removal machine, multiple iron removal stations are formed. To realize the above-mentioned working process, the iron removal machine with multiple iron removal operations can be provided with multiple flipping devices and multiple pressing devices to cooperate with each iron removal station to realize the cyclic cleaning of the iron removal rod group, but only one flipping device and one pressing device can be provided. When a flipping device and a pressing device are provided, the flipping device and the pressing device need to be respectively connected with a flipping displacement component and a pressing displacement component that can be reciprocated between multiple iron removal stations, so that the flipping device and the pressing device can be driven by the displacement component to move between multiple iron removal stations or iron removal rod groups, so as to realize the cyclic cleaning of the iron removal rod group of each iron removal station, or a container displacement component that can make each iron removal station or each iron removal rod group reciprocate to the flipping device and the pressing device is connected to the container, and the iron removal rod group and the container are moved synchronously through the container displacement component, so that each iron removal station is moved to the flipping device and the pressing device in turn, so as to realize the cyclic cleaning of the iron removal rod group of each iron removal station.

[0018] The iron removal rod group can be composed of a plurality of iron removal rods arranged in parallel, and the two ends of these iron removal rods can be respectively connected to a fixed plate to stabilize the distance between each iron removal rod and the shape of the entire iron removal rod group. In addition, these iron removal rods can be rods made of permanent magnetic materials or rods made of soft magnetic materials. The iron removal rods made of permanent magnetic materials can maintain their effective magnetism when entering and leaving the container, ensuring that metal or magnetic impurities are always adsorbed on the surface of the iron removal rods; the iron removal rods made of soft magnetic materials need to be arranged in the circumference of the container to wrap the magnetic area of ​​the container, which can be divided into an iron removal area and a flipping area. The container is placed in the iron removal area, and the iron removal rod group is placed in the flipping area after leaving the container and flipped in the flipping area, thereby ensuring that the iron removal rods made of soft magnetic materials can maintain effective magnetism during the entire iron removal and cleaning process, so that metal or magnetic impurities are always adsorbed on the surface of the iron removal rods.

[0019] When flushing the metal or magnetic impurities in the sealed space, the part of the iron removal rod group in the sealed space will also be rinsed clean at the same time, so that it can be ensured that after the iron removal rod group is flipped, the part facing the container side is the part with considerable adsorption effect from beginning to end. In order to prevent the residual water in the sealed space from falling into the container when the iron removal rod group is flipped again, the first mounting surface and the second mounting surface can be inclined to the lifting direction of the iron removal rod group and arranged toward the drain outlet, and the first mounting surface and the second mounting surface are parallel to each other. In this way, the residual water in the sealed space can be discharged toward the drain outlet under the guidance of the first mounting surface and the second mounting surface, and the first mounting surface and the second mounting surface are parallel to each other to ensure that after the iron removal rod group is flipped, no matter whether the sealed space is composed of the first mounting surface or the second mounting surface and the downward pressing moving part, the first mounting surface or the second mounting surface can still guide the residual water to be discharged toward the drain outlet.

[0020] The invention has the advantages of effectively shortening the non-iron removal time of the magnet bar group, improving the working efficiency of the iron remover, and having high device utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention and to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1

[0030] like Figure 1-2As shown, the iron removal machine includes a container 13, a lifting device 11, a turning device 10 and a pressing device, wherein the container 13 is a slurry conveying trough, and a plurality of groups of iron removal rod groups 12 are arranged in the slurry conveying trough, and the iron removal rod group 12 is composed of a plurality of iron removal rods made of permanent magnetic material. The iron removal rods are parallel to each other, and the two ends of these iron removal rods are respectively connected to a fixing plate 7. A scraper 8 for cleaning the surface of the iron removal rod group 12 is provided near the upper end of the iron removal rod group 12, and a plurality of iron removal rod through holes 16 that match the iron removal rods are arranged on the scraper 8. Each iron removal rod is interference fit with the corresponding iron removal rod through hole 16, so that the scraper 8 can move synchronously with the iron removal rod group 12.

[0031] In the present embodiment 1, the scraper 8 is a plate-like structure, and the two ends of the scraper 8 are respectively formed with a first supporting surface 26 and a second supporting surface 27, and the first supporting surface 26 and the second supporting surface 27 are parallel to each other and inclined to the longitudinal arrangement of the iron removal rod. In the present embodiment 1, in the initial position, the first supporting surface 26 of the scraper 8 faces the mixture in the container 13, and the second supporting surface 27 faces the pressing device. In addition, the scraper 8 is extended outwardly to form an extended edge to increase the bearing capacity of the scraper 8.

[0032] In the present embodiment 1, the lifting device 11 comprises a lifting frame, on which a vertically arranged lifting guide rail 17 is provided, the lifting guide rail 17 is connected to the container 13, and a lifting slider 14 is slidably connected to the lifting guide rail 17. A turning cylinder as a turning device 10 is connected to the lifting slider 14, the cylinder body of the turning cylinder is connected to the lifting slider 14, and a fixing clamp 15 is provided on the piston rod of the turning cylinder, and the fixing clamp 15 is connected to the scraper 8 to clamp the scraper 8.

[0033] In this embodiment 1, the downward pressing device includes a downward pressing cylinder 1, the piston rod of the downward pressing cylinder 1 is connected to a cleaning cover 3 as a downward pressing moving part 2, the cleaning cover 3 is hollow inside, and a drain outlet 6 and a water inlet are provided on the cleaning cover 3. A cleaning nozzle 4 as a cleaning component is installed at the water inlet, and the cleaning nozzle 4 is connected to an external water tank 5.

[0034] In the present embodiment 1, the iron remover is provided with only one set of pressing devices and a cleaning nozzle 4 matched with the pressing devices. The location of the pressing devices is the cleaning station of the iron remover in the present embodiment 1. In the container 13 of the present embodiment 1, there are multiple sets of iron removal rod groups 12 arranged longitudinally along the container 13. In order to enable each iron removal rod group 12 to be cleaned at the cleaning station, Figure 1As shown, a container displacement assembly is connected to the container 13 to drive the container 13 to move. The container displacement assembly includes a plurality of moving wheels 18 and a container moving guide rail 19 matched with the moving wheels 18. The moving wheels 18 are respectively installed on both sides of the slurry conveying trough, and the container moving guide rail 19 is arranged along the longitudinal direction of the container 13 and arranged below the moving wheels 18. The container moving guide rail 19 is provided with a groove arranged along its longitudinal direction. The moving wheel 18 is driven by a power device, and the movement in the groove of the container moving guide rail 19 drives the container 13 to move along the guide path of the groove, so that the iron removal rod group 12 to be cleaned is moved to the cleaning station in sequence and is located below the pressing device.

[0035] The working process of the iron remover of this embodiment 1 is as follows:

[0036] After the iron remover starts working, the mixture containing impurities such as metal or magnetic impurities flows into the slurry conveying trough, and the iron removal rod group 12 is in the slurry conveying trough and starts to remove iron, absorbing the iron powder in the mixture to its own surface. At this time, the scraper 8 is above the mixture and outside the slurry conveying trough. The first bearing surface 26 of the scraper 8 faces the mixture in the slurry conveying trough, and the second bearing surface 27 of the scraper 8 faces the downward pressure cylinder 1. After the iron remover has been working for a period of time, after a certain amount of metal or magnetic impurities are adsorbed on the surface of the iron removal rod group 12, the lifting slider 14 is driven by the power device to drive the scraper 8 to rise. Since the scraper 8 and the iron removal rod group 12 move synchronously, the iron removal rod group 12 will rise at the same time and leave the slurry conveying trough. Subsequently, the flipping cylinder is activated to flip the scraper 8 and the iron removal rod group 12 180°, so that the first supporting surface 26 of the scraper 8 faces the downward pressure device, and the second supporting surface 27 of the scraper 8 faces the mixture in the slurry conveying trough. At this time, the part of the iron removal rod group 12 that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will also flip to face the downward pressure cylinder, while the part of the iron removal rod group 12 that is not immersed in the mixture and has a clean surface will flip to face the mixture in the slurry conveying trough.

[0037] Subsequently, the downward pressure cylinder 1 is activated, causing the piston rod to be pressed down until the cleaning cover 3 is connected to the iron removal rod group 12, and the pressure continues until the cleaning cover 3 is pressed against the first bearing surface 26 of the scraper 8. At this time, since the flip cylinder does not operate, the scraper 8 is fixed in position, and a sealed space is formed between the cleaning cover 3 and the scraper 8. At the same time, the part of the iron removal rod group 12 that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will be forced to be pressed down by the piston rod of the downward pressure cylinder 1, so that the part moves from the first bearing surface 26 of the scraper 8 to the second bearing surface 27 of the scraper 8, and in this process, the metal or magnetic impurities on the surface are scraped off by the scraper 8. The scraped metal or magnetic impurities will be carried by the first bearing surface 26 and sealed in the sealed space. Subsequently, the lifting slider 14 moves, driving the iron removal rod group 12 and the scraper 8 to synchronously descend relative to the slurry conveying trough and return to the slurry conveying trough. The part of the iron removal rod group 12 on the side of the second supporting surface 27 of the scraper 8 will be re-immersed in the mixture to continue the iron removal work, while the cleaning nozzle 4 in the sealed space flushes the entire sealed space with water flow, so that the metal or magnetic impurities in the sealed space are discharged from the drain. At this point, the iron removal machine completes an iron removal cleaning cycle. In the next iron removal cleaning cycle, the cleaning cover 3 will be pressed onto the second supporting surface 27 and form a sealed space with the scraper 8. The metal or magnetic impurities scraped off in this iron removal cleaning cycle will be supported by the second supporting surface 27.

[0038] After performing one or several iron removal cleaning cycles, the moving wheel 18 moves along the container moving guide rail 19 under the action of the power device, driving the slurry conveying trough and the iron removal rod group 12 arranged in the slurry conveying trough to move, and one of the iron removal rod groups 12 that did not participate in the cleaning work in the previous iron removal cleaning cycle is moved to the cleaning station, and the above-mentioned iron removal cleaning cycle is repeated.

[0039] Example 2

[0040] The difference between this embodiment 2 and embodiment 1 is that Figure 3 As shown, in this embodiment 2, a downward pressure displacement assembly is provided to drive the downward pressure device and the cleaning nozzle 4 matched with the downward pressure device to move, and the downward pressure displacement assembly includes a downward pressure device fixed beam 20, a support column 28 and a frame moving guide rail 22 arranged along the longitudinal direction of the container 13, and a frame moving guide block 21 is formed at the end of the support column 28, and the frame moving guide rail 22 is slidably connected with the frame moving guide block 21. In this embodiment 2, the iron removal rod group 12 will remain motionless in the container 13, and the downward pressure device drives the frame moving guide block 21 to move longitudinally along the frame moving guide rail 22 through a power device, and moves to the top of the iron removal rod group 12 to be cleaned.

[0041] The process of the iron removal cleaning cycle in this embodiment 2 is the same as the process of the iron removal cleaning cycle in embodiment 1. After one or several iron removal cleaning cycles, the pressing device, driven by the power device, drives the pressing device to move along the frame moving guide rail 22 through the sliding of the frame moving guide block 21 relative to the frame moving guide rail 22, until the pressing device is moved to the top of one of the iron removal rod groups 12 that did not participate in the cleaning work in the previous iron removal cleaning cycle, and the iron removal cleaning cycle is restarted.

[0042] Example 3

[0043] The difference between this embodiment 3 and embodiment 1 is that Figure 3 As shown, in this embodiment 3, the container 13 includes two sub-containers 131, and the two sub-containers 131 are two parallel slurry conveying troughs, each of which is provided with multiple groups of iron removal rod groups 12, and the positions of each iron removal rod group 12 are staggered. The iron removal machine of this embodiment 3 is not provided with a lifting device 11, but is provided with a turning device 10. The turning device 10 is composed of left and right turning cylinders, and the piston rod of the left and right turning cylinders can reciprocate between the two slurry conveying troughs. The piston rod of the left and right turning cylinders is connected to the scraper 8 through a fixing clamp 15. Each iron removal rod group 12 cooperates with a left and right turning cylinder. In this embodiment 3, a turning displacement assembly is also provided, and the turning displacement assembly includes a support rod 29 supporting the left and right turning cylinders and a cylinder moving guide rail 30 arranged longitudinally along the container 13, the support rod 29 is connected to the container 13, and the end of the support rod 29 is formed with a cylinder moving guide block 31, and the cylinder moving guide block 31 is slidably connected to the cylinder moving guide rail 30.

[0044] In this embodiment 3, the iron remover is provided with two sets of pressing devices and two sets of cleaning nozzles 4 matched with the pressing devices, and each pressing device is matched with each slurry conveying trough. The location of the pressing device is the cleaning station of the iron remover in this embodiment 3. In the container 13 of this embodiment 3, there are multiple sets of iron removal rod groups 12 arranged longitudinally along the container 13. In order to enable each iron removal rod group 12 to be cleaned at the cleaning station, Figure 3 As shown, a container displacement assembly is connected to the container 13 to drive the container 13 to move. The container displacement assembly includes a plurality of moving wheels 18 and a container moving guide rail 19 matched with the moving wheels 18. The moving wheels 18 are respectively installed on both sides of the slurry conveying trough. The container moving guide rail 19 is arranged along the longitudinal direction of the container 13 and arranged below the moving wheels 18. The container moving guide rail 19 is provided with a groove arranged along its longitudinal direction. The moving wheel 18 is driven by a power device, and the movement in the groove of the container moving guide rail 19 drives the container 13 to move along the guide path of the groove, so that the iron removal rod group 12 to be cleaned is moved to the cleaning station in sequence and is located below the pressing device.

[0045] The working process of the iron remover of this embodiment 3 is as follows:

[0046] After the iron remover starts working, the mixture containing impurities such as metal or magnetic impurities flows into the slurry conveying trough, and the iron removal rod group 12 is in the slurry conveying trough and starts to remove iron, adsorbing the iron powder in the mixture to its own surface. At this time, the scraper 8 is above the mixture and outside the slurry conveying trough. The first bearing surface 26 of the scraper 8 faces the mixture in the slurry conveying trough, and the second bearing surface 27 of the scraper 8 faces the downward pressure cylinder. After the iron remover has been working for a period of time, and a certain amount of metal or magnetic impurities are adsorbed on the surface of the iron removal rod group 12, the moving wheel 18 moves along the container moving guide rail 19 under the action of the power device, driving the slurry conveying trough and the iron removal rod group 12 arranged in the slurry conveying trough and the flip cylinder cooperating with the iron removal rod group 12 to move, and the iron removal rod group 12 that needs to be cleaned is moved to a place opposite to the cleaning station position of another slurry conveying trough. Subsequently, the left and right flip cylinders are actuated to drive the scraper 8 and the iron removal rod group 12 to rotate and rise, detach from the originally working slurry conveying trough, and flip to the top of another slurry conveying trough, and enter the cleaning station of another slurry conveying trough. At this time, the first supporting surface 26 of the scraper 8 faces the downward pressure device, and the second supporting surface 27 of the scraper 8 faces the mixture in the slurry conveying trough. At this time, the part of the iron removal rod group 12 that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will also flip to face the downward pressure cylinder 1, while the part of the iron removal rod group 12 that is not immersed in the mixture and has a clean surface will flip to face the mixture in the slurry conveying trough.

[0047] Subsequently, the downward pressure cylinder 1 is actuated, causing the piston rod to be pressed down until the cleaning cover 3 is connected to the iron removal rod group 12, and the pressure continues until the cleaning cover 3 is pressed against the first bearing surface 26 of the scraper 8. At this time, since the flip cylinder does not move, the scraper 8 is fixed in position, and a sealed space is formed between the cleaning cover 3 and the scraper 8. At the same time, the part of the iron removal rod group 12 that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will be forced to be pressed down by the piston rod of the downward pressure cylinder 1, so that the part moves from the first bearing surface 26 of the scraper 8 to the second bearing surface 27 of the scraper 8, and in this process, the metal or magnetic impurities on the surface are scraped off by the scraper 8. The scraped metal or magnetic impurities will be supported by the first bearing surface 26 and sealed in the sealed space. The iron removal rod group 12 is forced to be pressed down by the piston rod of the downward pressure cylinder 1, that is, it returns to the mixture of the slurry conveying trough to continue the iron removal work. The cleaning nozzle 4 in the sealed space flushes the entire sealed space with water flow, so that the metal or magnetic impurities in the sealed space are discharged from the drain port 6. At this point, the iron remover completes an iron removal cleaning cycle. In the next iron removal cleaning cycle, the cleaning cover 3 will be pressed onto the second supporting surface 27 and form a sealed space with the scraper 8. The metal or magnetic impurities scraped off in the iron removal cleaning cycle will be supported by the second supporting surface 27.

[0049] The difference between this embodiment 4 and embodiment 3 is that in this embodiment 4, the iron remover is provided with a set of downward pressing devices and a cleaning nozzle 4 matched with the downward pressing devices, and a downward pressing displacement assembly is provided to drive the downward pressing devices and the cleaning nozzle 4 matched with the downward pressing devices to move. In this embodiment 4, the downward pressing displacement assembly includes a downward pressing device transverse guide rail 32, a support column 28 and a frame moving guide rail 22 arranged along the longitudinal direction of the container 13; the downward pressing device is connected to a downward pressing device transverse guide block 33, and the downward pressing device transverse guide block 33 is slidably connected to the downward pressing device transverse guide rail 32; the end of the support column 28 is formed with a frame moving guide block 21, and the frame moving guide rail 22 is slidably connected to the frame moving guide block 21. In this embodiment 4, the downward displacement assembly drives the downward pressure device transverse guide block 33 to move longitudinally along the downward pressure device transverse guide rail 32 through the power device, and reciprocates between the two slurry conveying troughs. The power device drives the frame moving guide block 21 to move longitudinally along the frame moving guide rail 22, and moves to the top of the iron removal rod group 12 to be cleaned.

[0050] The process of the iron removal cleaning cycle in this embodiment 4 is the same as the process of the iron removal cleaning cycle in embodiment 3. After one or several iron removal cleaning cycles, the pressing device, driven by each power device, moves along the guide direction of the pressing device transverse guide rail 32 and the frame moving guide rail 22 as needed, thereby moving to the top of one of the iron removal rod groups 12 that needs to be cleaned, and restarting the iron removal cleaning cycle.

[0051] Example 5

[0052] The difference between this embodiment 5 and embodiment 1 is that in this embodiment 5, each iron removal rod group 12 is composed of a plurality of iron removal rods made of soft magnetic material, magnets 23 are arranged on both sides of the slurry conveying trough, and a magnetic zone is formed between the magnets on both sides. The magnetic zone includes an iron removal zone 24 and a flipping zone 25. The flipping zone 25 is above the iron removal zone 24, the slurry conveying trough is located in the iron removal zone 24, and the flipping cylinder is located in the flipping zone 25.

[0053] The working process of this embodiment 5 is as follows:

[0054] After the iron remover starts working, a mixture containing impurities such as metal or magnetic impurities flows into the slurry conveying trough, and the iron removal rod group 12 is in the slurry conveying trough and starts to remove iron, absorbing the iron powder in the mixture to its own surface. At this time, the scraper 8 is above the mixture, outside the slurry conveying trough and in the flipping zone 25. The first bearing surface 26 of the scraper 8 faces the mixture in the slurry conveying trough, and the second bearing surface 27 of the scraper 8 faces the downward pressure cylinder 1. After the iron remover has been working for a period of time, after a certain amount of metal or magnetic impurities are adsorbed on the surface of the iron removal rod group 12, the lifting slider 14 is driven by the power device to drive the scraper 8 to rise. Since the scraper 8 moves synchronously with the iron removal rod group 12, the iron removal rod group 12 will rise at the same time and detach from the slurry conveying trough until the iron removal rod group as a whole is located in the flipping zone 25. Subsequently, the flipping cylinder is activated to flip the scraper 8 and the iron removal rod group 12 180°, so that the first supporting surface 26 of the scraper 8 faces the downward pressure device, and the second supporting surface 27 of the scraper 8 faces the mixture in the slurry conveying trough. At this time, the part of the iron removal rod group 12 that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will also flip to face the downward pressure cylinder, while the part of the iron removal rod group 12 that is not immersed in the mixture and has a clean surface will flip to face the mixture in the slurry conveying trough.

[0055] Subsequently, the downward pressure cylinder 1 is activated, causing the piston rod to be pressed down until the cleaning cover 3 is connected to the iron removal rod group 12, and the pressure continues until the cleaning cover 3 is pressed against the first bearing surface 26 of the scraper 8. At this time, since the flip cylinder does not operate, the scraper 8 is fixed in position, and a sealed space is formed between the cleaning cover 3 and the scraper 8. At the same time, the part of the iron removal rod group 12 that was originally immersed in the mixture and adsorbed with metal or magnetic impurities will be forced to be pressed down by the piston rod of the downward pressure cylinder 1, so that the part moves from the first bearing surface 26 of the scraper 8 to the second bearing surface 27 of the scraper 8, and in this process, the metal or magnetic impurities on the surface are scraped off by the scraper 8. The scraped metal or magnetic impurities will be carried by the first bearing surface 26 and sealed in the sealed space. Subsequently, the lifting slider 14 moves, driving the iron removal rod group 12 and the scraper 8 to synchronously descend relative to the slurry conveying trough and return to the slurry conveying trough. The part of the iron removal rod group 12 on the side of the second supporting surface 27 of the scraper 8 will be re-immersed in the mixture to continue the iron removal work, while the cleaning nozzle 4 in the sealed space flushes the entire sealed space with water flow, so that the metal or magnetic impurities in the sealed space are discharged from the drain. At this point, the iron removal machine completes an iron removal cleaning cycle. In the next iron removal cleaning cycle, the cleaning cover 3 will be pressed onto the second supporting surface 27 and form a sealed space with the scraper 8. The metal or magnetic impurities scraped off in this iron removal cleaning cycle will be supported by the second supporting surface 27.

[0056] After performing one or several iron removal cleaning cycles, the moving wheel 18 moves along the container moving guide rail 19 under the action of the power device, driving the slurry conveying trough and the iron removal rod group 12 arranged in the slurry conveying trough to move, and one of the iron removal rod groups 12 that did not participate in the cleaning work in the previous iron removal cleaning cycle is moved to the cleaning station, and the above-mentioned iron removal cleaning cycle is repeated.

[0057] This specification lists only the preferred embodiments of the present invention. All equivalent technical changes made under the working principle and concept of the present invention are deemed to be within the protection scope of the present invention.
