Permanent magnet separator for clay sand production

Abstract

This utility model relates to the field of permanent magnet separator technology, specifically a permanent magnet separator for clay sand production, including a frame and a belt. A support frame is fixedly connected to the lower surface of the frame. A magnet box is provided on one side of the belt, and lifting and adjusting mechanisms are provided on both sides of the magnet box. In use, the magnet is placed inside the magnet box. By adjusting the lifting and adjusting mechanisms, the position of the magnet box can be adjusted, allowing the magnet inside the box to move closer to or further away from the belt. This adjusts the force with which the magnet attracts the magnetic material on the belt, preventing excessive attraction that could press the belt against the magnet box. This ensures the belt does not contact the magnet box during operation. Furthermore, the number of magnets inside the magnet box can be increased or decreased to adjust the magnetic force.

Description

Technical Field

[0001] This utility model relates to the field of permanent magnet separator technology, specifically a permanent magnet separator for clay sand production. Background Technology

[0002] In the production of clay sand, it is necessary to process the clay sand. A permanent magnet separator can be used to remove magnetic impurities mixed in the clay sand.

[0003] The currently disclosed belt-type permanent magnet separator (CN207722952U) features a frame, a conveyor belt, and a magnet located in the middle of the conveyor belt. The frame has a drive roller and a driven roller fixed at both ends. The conveyor belt is fitted onto the drive roller and the driven roller. A pulley is attached to the magnet, protruding from the magnet and resting against the inner surface of the belt. This creates a gap between the belt and the magnet, preventing wear and increasing the belt's lifespan. However, the belt is made of a flexible material, allowing it to deform. The pulley support is only a point; at the pulley support, the belt cannot contact the magnet. Without pulley support, the belt may still contact the magnet, especially when there are many magnetic impurities on one side of the belt. The magnet attracts these impurities, causing them to press the belt towards the magnet, potentially deforming the belt and causing friction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a permanent magnet separator for clay sand production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a permanent magnet separator for clay sand production, comprising a frame and a belt, wherein a support frame is fixedly connected to the lower surface of the frame, a magnet box is provided on one side of the belt, and a lifting adjustment mechanism is provided on both sides of the magnet box.

[0006] Preferably, the lifting and adjusting mechanism includes a connecting block fixedly connected to the magnet box, a lead screw rotatably connected to one side wall of the support frame, and one end of the lead screw passes through the connecting block and the frame. The lead screw is threadedly connected to the connecting block, and a driving component is provided on one side of the frame.

[0007] Preferably, the drive assembly includes a rotating shaft that passes through the frame, and two first gears are fixedly connected to the outer wall of the rotating shaft. One end of each of the two lead screws is fixedly connected to a second gear, and the two first gears mesh with the two second gears respectively.

[0008] Preferably, a bearing is fixedly sleeved on the outer wall of the lead screw, and the outer wall of the bearing is fixedly connected to the frame.

[0009] Preferably, one end of the rotating shaft has an internal hexagonal hole.

[0010] Preferably, a sliding rod is fixedly connected to one side wall of the support frame, and one end of the sliding rod passes through the connecting block and is fixedly connected to the frame body.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, when in use, the magnet is placed inside the magnet box. By setting up a lifting and adjusting mechanism, the position of the magnet box can be adjusted, thereby moving the magnet inside the magnet box away from or closer to the belt. This adjusts the force with which the magnet inside the magnet box attracts the magnetic material on the belt, preventing the attraction from being too strong and pressing the belt against the magnet box. This ensures that the belt does not contact the magnet box during operation. Furthermore, the number of magnets inside the magnet box can be increased or decreased to increase or decrease the magnetic force. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-4 A permanent magnet separator for clay sand production includes a frame 1 and a belt 2. A support frame 3 is fixedly connected to the lower surface of the frame 1. A magnet box 4 is provided on one side of the belt 2, and a lifting adjustment mechanism is provided on both sides of the magnet box 4.

[0020] As can be seen from the above structure, when in use, the magnet is placed in the magnet box 4. By setting up a lifting adjustment mechanism, the position of the magnet box 4 can be adjusted, so that the magnet in the magnet box 4 moves away from or closer to the belt 2. This adjusts the force of the magnet in the magnet box 4 attracting the magnetic material on the belt 2, preventing the attraction from being too strong and pressing the belt 2 onto the magnet box 4. This ensures that the belt 2 does not contact the magnet box 4 when running, and the number of magnets in the magnet box 4 can be increased or decreased to increase or decrease the magnitude of the magnetic force.

[0021] Furthermore, the lifting and adjusting mechanism includes a connecting block 5 fixedly connected to the magnet housing 4, a lead screw 6 rotatably connected to one side wall of the support frame 3, and one end of the lead screw 6 passes through the connecting block 5 and is set to the frame 1. The lead screw 6 is threadedly connected to the connecting block 5, and a drive assembly is set on one side of the frame 1. By setting the connecting block 5, the lead screw 6 and the drive assembly to work together, the drive assembly can be used to drive the lead screw 6 to rotate, and the rotating lead screw 6 can drive the connecting block 5 and the magnet housing 4 to move.

[0022] Furthermore, the drive assembly includes a rotating shaft 7 that passes through the frame 1, and two first gears 8 are fixedly connected to the outer wall of the rotating shaft 7. One end of each of the two lead screws 6 is fixedly connected to a second gear 9, and the two first gears 8 mesh with the two second gears 9 respectively. By setting the rotating shaft 7, the first gears 8 and the second gears 9 to work together, two lifting and adjusting mechanisms can be driven simultaneously. When in use, rotating the rotating shaft 7 can drive the first gears 8 to rotate, the rotating first gears 8 can drive the second gears 9 to rotate, and the rotating second gears 9 can drive the lead screws 6.

[0023] Furthermore, a bearing 10 is fixedly sleeved on the outer wall of the lead screw 6, and the outer wall of the bearing 10 is fixedly connected to the frame 1; by setting the bearing 10, the stability of the rotation of the lead screw 6 can be increased.

[0024] Furthermore, one end of the rotating shaft 7 is provided with an internal hexagonal hole 11; by providing the internal hexagonal hole 11, the rotating shaft 7 can be rotated by using an internal hexagonal wrench and the internal hexagonal hole 11.

[0025] Furthermore, a sliding rod 12 is fixedly connected to one side wall of the support frame 3, and one end of the sliding rod 12 passes through the connecting block 5 and is fixedly connected to the frame 1; by setting the sliding rod 12, the connecting block 5 and the magnet box 4 can be limited, which can increase the stability of the movement of the limiting connecting block 5 and the magnet box 4.

[0026] When the height of the magnet housing 4 needs to be adjusted, a tool can be inserted into the internal hexagonal hole 11 to drive the rotating shaft 7 to rotate. Since the first gear 8 and the second gear 9 mesh with each other, the lead screw 6 connected to the second gear 9 will rotate, and the connecting block 5 threaded on the lead screw 6 will be adjusted up and down along the lead screw 6. This will achieve the height adjustment of the magnet housing 4, ensuring that the structure of the magnet housing 4 does not come into contact with the belt 2 while separating magnetic impurities in the clay sand, reducing wear between structures and improving the adjustability of the separation structure.

[0027] During equipment operation, when the clay sand moves along the conveyor belt 2 and passes through the magnetic field area formed by the magnet box 4, the magnetic impurities mixed in are attracted to the surface of the conveyor belt 2 by the strong magnetic field of the magnet box 4. The non-magnetic clay sand continues to move along the conveyor belt 2 to the discharge port, thus achieving the separation of magnetic impurities from clay sand. The magnetic impurities adsorbed on the surface of the conveyor belt 2 or the magnet box 4 can be periodically removed by cleaning devices such as scrapers and brushes to ensure the continuous and efficient operation of the separator.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
