[0002] At present, in the field of kaolin magnetic separation and iron purification technology, the most widely used magnetic separation equipment is a discontinuous high gradient magnetic separator, such as Figure 1 As shown. Since the upper pole head 1' must often be removed during use in order to perform maintenance on the magnetic medium 2', including cleaning and replacement, it often causes many inconveniences in industrial applications. For example, the upper pole head of the existing high gradient magnetic separator is fastened to the armor 4' located around the upper pole head 1' by multiple bolts 3'. If the magnetic medium 2' is to be maintained, it is necessary to first remove all the multiple fastening bolts 3'. If the bolts 3' are severely corroded, it is also difficult to remove. Therefore, maintenance is time-consuming and laborious. Even after all the bolts 3' are removed, it is necessary to manually operate the lifting equipment to move to the top of the high gradient magnetic separator and then lift the upper pole head 1' relative to the high gradient magnetic separator before cleaning or replacing the magnetic medium 2', and finally hoist it into the high gradient magnetic separator. The whole process is cumbersome to operate, and thus the maintenance efficiency is low.

[0031] refer to Figure 2 and Figure 7As an object of the present invention, an upper magnetic pole head displacement device 10 of a high gradient magnetic separator is provided, which includes a support 11 and at least one first driving device 12. The support 11 is used to be arranged on a high gradient magnetic separator 20, and the high gradient magnetic separator 20 includes an upper magnetic pole head 21 and a magnetic concentrating medium 22 located below the upper magnetic pole head 21. The first driving device 12 is supported by the support 11 and is used to be connected to the upper magnetic pole head 21 for driving, so that the first driving device 12 drives the upper magnetic pole head 21 upwardly along a first direction, specifically a vertical direction, away from the high gradient magnetic separator 20, especially the armor iron 25 surrounding the upper magnetic pole head 21, so that the magnetic concentrating medium 22 is exposed so that the magnetic concentrating medium 22 can be maintained, and after the magnetic concentrating medium 22 is maintained, the first driving device 12 drives the upper magnetic pole head 21 downwardly along the first direction so that the upper magnetic pole head 21 is restored to the high gradient magnetic separator 20. In this case, after the upper magnetic pole head shifting device 10 of the high gradient magnetic separator provided by the utility model drives the upper magnetic pole head 21 to a reasonable distance away from the high gradient magnetic separator 20 by the first driving device 12, not only the magnetic medium 22 is exposed, but also the reasonable distance away can provide necessary maintenance space, so that the magnetic medium 22 can be conveniently maintained including cleaning and replacement, and the upper magnetic pole head 21 is driven downwardly in the first direction by the first driving device 12 to be relocated on the high gradient magnetic separator 20, so that the downward driving force can ensure the reliable cooperation of the upper magnetic pole head 21 in the high gradient magnetic separator 20, especially with the armored iron 25. In this way, it is avoided that multiple bolts are used to fasten the upper pole head 21 to the armor 25 located at its periphery, thereby eliminating the need to remove multiple fastening bolts before maintaining the magnetic medium 22, thereby avoiding the difficulty of disassembly caused by severe rust on the bolts. In addition, the first drive device 12 is configured to be connected to the drive of the upper pole head 21, thereby avoiding the cumbersome operation caused by the traditional use of lifting equipment to lift the upper pole head 21 relative to the high gradient magnetic separator 20. Therefore, the upper pole head shifting device 10 of the high gradient magnetic separator brings beneficial technical effects of saving time and effort and high maintenance efficiency for the maintenance of the magnetic medium 22.

In this case, on the basis of configuring the first driving device 12, the second driving device 13 and the moving device 15 are further configured, so that after the first driving device 12 lifts the upper magnetic pole head 21 to an appropriate height relative to the high gradient magnetic separator 20, the second driving device 13 can further drive the moving device 15 to move and park the upper magnetic pole head 21 to a preset position that does not affect the cleaning or replacement of the magnetic medium 22. In this way, a larger and more free maintenance space can be provided for the maintenance of the magnetic medium 22, thereby making the maintenance of the magnetic medium 22 more convenient.

[0033] Please refer to Figure 7 Preferably, the mobile device 15 is configured as a mobile trolley, which includes a frame 151 and a plurality of wheels 152 that movably support the frame 151. The first drive device 12 is disposed on the frame 151, for example, along the first direction. The second drive device 13 is connected to the frame 151 in a driving manner along the second direction. The support 11 is configured as a pair and is provided with guide rails 1101 that are disposed parallel and opposite to each other along the first direction. Each guide rail 1101 is matched with at least two wheels 152, for example, in a rolling manner. Preferably, the mobile trolley uses two pairs of wheels 152 that are opposite to each other on a horizontal plane perpendicular to the second direction to roll with the two guide rails 1101. Therefore, by using the mobile trolley as the mobile device 15, the rolling cooperation between the wheels 152 and the guide rails 1101 can be achieved, thereby ensuring the accuracy and reliability of the second drive device 13 driving the mobile trolley to move.

The first beam 1511 and the second beam 1512 can be moved up and down in the open part. Both adjacent ends of the first beam 1511 and the second beam 1512 are fixedly connected to the same third beam 1513, for example, by a fixed sleeve. The relative positions and fixed connection methods between the first beam 1511, the second beam 1512 and the third beam 1513 can be selected according to actual needs and are within the protection scope of the utility model.

The support frame 1514 supports at least one first drive device 12 and at least one guide assembly 14. In this way, not only the overall structure of the mobile trolley is compact, the support strength for each drive device 12, 13 and the guide assembly 14 is large, and by setting the guide assembly 14, the stability and reliability of the first drive device 12 driving the upper magnetic pole head 21 to move can be improved.

[0035] Please refer to Figure 2 , Figure 5 and Figure 6 Specifically, the first driving device 12 includes a first hydraulic cylinder, the second driving device 13 includes a second hydraulic cylinder, the first piston rod of the first hydraulic cylinder is fixedly connected to the upper magnetic pole head 21, the second piston rod of the second hydraulic cylinder is drivingly connected to the second vehicle beam 1512, the guide assembly 14 includes a guide rod 141 and a sleeve 142, the sleeve 142 is fixedly connected to the upper magnetic pole head 21, one end of the guide rod 141 is fixedly connected to the support frame 1514, and the other end of the guide rod 141 is slidably inserted in the sleeve hole of the sleeve 142 to guide the lifting movement of the upper magnetic pole head 21 driven by the telescopic movement of the first piston rod, and the first piston rod and the guide rod 141 are located in the open portion and are relatively parallel and spaced in the second direction. In this case, the first driving device 12 and the second driving device 13 use hydraulic cylinders to provide driving force, which is sufficient to provide the lifting driving force and translation driving force for lifting the upper magnetic pole head 21 and translating the upper magnetic pole head 21. Moreover, the guide assembly 14 uses a slidingly matched guide rod 141 and a sliding sleeve 142, which has the function of guiding the lifting and lowering of the upper magnetic pole head 21 well.

[0036] Preferably, the first hydraulic cylinder and the guide assembly 14 are each provided with three, the second hydraulic cylinder is provided with two, the second piston rods of the two second hydraulic cylinders of the support frame are respectively connected to the two opposite ends of a second vehicle beam 1512 by driving, and the three first hydraulic cylinders and the three guide assemblies 14 are alternately supported on the support frame 1514 at the same center angle relative to the center of the ring, so that the projections of each first hydraulic cylinder, especially its first piston rod, and each guide assembly 14, especially its guide rod 141, on the upper magnetic pole head 21 are alternately and evenly distributed.

[0037] Please refer to Figures 2 to 6Specifically, the upper magnetic pole head 21 further includes a support frame 211 and a pair of first flanges 212 extending relatively from the support frame 211 along the second direction. For example, a separator 26 connected to the upper magnetic pole head 21 and receiving the ore to be separated may be provided on the support frame 211. The separator 26 may be raised and lowered in the open portion along with the upper magnetic pole head 21. A guide column 16 is fixed on a first flange 212. The first piston rod 12 is preferably eccentrically fixedly connected to the guide column 16, so that the first piston rod 12 can be used as a The force applied to the guide column 16 can be decomposed into components in the vertical and horizontal directions, which can help prevent the horizontal deviation of the upper magnetic pole head 21 while driving the upper magnetic pole head 21 to rise and fall. When the upper magnetic pole head 21 is in normal working condition, a pair of first flanges 212 are used to abut and seal with a pair of second flanges 24 of the high gradient magnetic separator 20, on which elastic seals 23 are respectively provided. Therefore, the upper magnetic pole head 21 does not need to be fastened to the high gradient magnetic separator 20, especially the armor iron 25, by multiple bolts. On the basis of the above, the upper magnetic pole head 21 can be detachably sealed with the high gradient magnetic separator 20, the sleeve 142 includes a bracket 1421 with a through hole and a collar 1422 with a sleeve hole, the bracket 1421 is fixed to the other first flange 212, the collar 1422 is plugged into the through hole and fixed to the bracket 1421 by a threaded connection method such as screws, bolts, etc. and the threaded hole, and the support frame 1514 is provided with four fixing parts 15141, each fixing part 15141 is fixed by a The plate 17 is fixedly connected to a first beam 1511 or a second beam 1512.

The support frame 1514 is provided with a plurality of through holes. The cylinder barrel of at least one first hydraulic cylinder passes through at least one through hole and is fixed to the support frame 1514 through a fixing ring 18. Therefore, the first hydraulic cylinder 12 is reliably supported and limited. At least one guide rod 141 is correspondingly inserted into at least one other through hole of the support frame 1514. The end of the guide rod 141 away from the upper magnetic pole head 21 is provided with a flange 1411. The flange 1411 and the support frame 1514 are correspondingly provided with a plurality of pairs of connection holes respectively connected and fixed by a plurality of connecting members.

The first direction is the vertical direction, and the second direction is the horizontal direction. The support 11 extends in the second direction in suspension relative to an armored iron 25 of the high gradient magnetic separator 20. The first support beam 19 is inclined to be fixed to the suspended extended end of the support 11 and an upper magnetic pole seat of the high gradient magnetic separator 20, thereby providing support force for the support 11. At this time, the support plates 111 in this case are made into separate parts relative to a pair of support plates, so that the support plates 111 actually have two pairs. The support plate 111 extends upward along the first direction and one end is used to be fixed to the armored iron 25 of the high gradient magnetic separator 20. The other end of the support plate 111 supports the cylinder barrel of the second hydraulic cylinder 13 passed through it.

It can also be said that the first support beam 19 and the second support beam 110 are inclined in different directions relative to the second direction. In addition, it should be noted that the number of first support beams 19 is set to correspond to the number of supports 11, that is, guide rails 1101, and the number of second support beams 110 and support plates 111 is set to correspond to the number of second drive devices 13. In addition, each second drive device 13 can also be provided with two support plates 111, one of which is fixed to the armor 25, and the other is fixed to the second support beam 110 and the cylinder barrel of the second hydraulic cylinder 13, and is also fixed to the support plate 111, so that it is easy to fix and install to improve assembly efficiency and improve fixation reliability. In addition, each support beam 19, 110 and the above-mentioned vehicle beams 1511, 1512, 1513 and support 11 can be made of I-beams, which is conducive to controlling costs while obtaining sufficient strength. Therefore, each support 11 and the second driving device 13 can obtain stable support, and the entire structure of the upper magnetic pole head displacement device 10 is highly stable, which is conducive to ensuring that the upper magnetic pole head 21 is driven to move vertically and horizontally with high stability and accuracy.

Since the high gradient magnetic separation device 20 includes the upper magnetic pole head shifting device 10 of any of the above high gradient magnetic separators, it has the corresponding technical effects, which will not be described in detail here, so the high gradient magnetic separator 20 has the advantages of saving time and effort and high maintenance efficiency for the maintenance of the magnetic medium 22.
