Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of magnetic separator baffle adjustment, specifically a tailing adjusting device for a magnetic separator. BACKGROUND

[0002] Magnetic separation equipment refers to the equipment used to separate materials with magnetism from other materials according to the magnetic characteristics of the materials. It is generally used for the production and screening of magnetic minerals such as magnetite. The magnetic separation equipment is also commonly known as a magnetic separator or a magnetic separation machine. The position of the baffle of the magnetic separator, especially the upper and lower tailing baffles, has a direct impact on the tailing grade. The closer the baffle is to the cylinder skin, the more tailing there is, and the higher the tailing grade. The farther the baffle is from the cylinder skin, the less tailing there is, and the lower the tailing grade. Therefore, when magnetic separation is performed on tailings with different properties, the position of the baffle needs to be adjusted to ensure that the tailing grade meets the requirements of mineral processing.

[0003] The prior art magnetic separator can only adjust the distance between the baffle and the cylinder skin, and cannot accurately adjust the inclination angle of the baffle and the relative position between the upper end of the baffle and the cylinder skin. Therefore, the adjustment accuracy needs to be further improved. Thus, we propose a tailing adjusting device for a magnetic separator. SUMMARY

[0004] The utility model discloses a tailing adjusting device for a magnetic separator, which can adjust the position of the electromagnet to change the position of the baffle, the distance between the baffle and the cylinder skin, and the inclination angle of the baffle by using the magnetic attraction between the electromagnet and the magnet block on the upper and lower sides of the baffle. The electromagnet can lock the position of the baffle after being powered on. This device can accurately adjust the baffle for tailings with different properties to meet the requirements of mineral processing, and solves the problems mentioned in the background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a tailing adjusting device for a magnetic separator, which comprises a side plate and a baffle. The baffle is placed between the front and rear end side plates. The upper and lower sides of the baffle are fixed with adsorption blocks that are in contact with the inner surface of the side plate. The surface of the adsorption block is provided with a plate groove and a magnet block. A plurality of sliding grooves are horizontally arranged in the inner part of the adsorption block on the side of the plate groove. A sliding block is slidably arranged in the sliding groove. A connecting rod is fixedly connected between the sliding block and the magnet block. A spring is sleeved around the outer circle of the connecting rod between the sliding block and the sliding groove. An electromagnet is magnetically attracted to the outer surface of the side plate at the position of the adsorption block. A handle is connected between the electromagnets on the upper and lower sides of the same side plate.

[0006] By adopting the technical scheme, when the position, distance and inclination angle of the baffle need to be adjusted, the upper and lower electromagnets are first powered off, the baffle is moved by moving the upper and lower electromagnets to change the position of the upper part of the baffle and the distance between the baffle and the cylinder skin, then the upper electromagnet is powered on to adsorb and lock the upper part of the baffle, the position of the lower electromagnet is rotated to rotate and adjust the inclination angle of the baffle, and the lower electromagnet is powered on to adsorb and lock the baffle as a whole.

[0007] Optionally, the outer side surface of the side plate is provided with a cross grid, and the cross grid is uniformly distributed on the outer side surface of the side plate.

[0008] By adopting the technical scheme, the position of the electromagnet can be adjusted more accurately through the cross grid.

[0009] Optionally, the outer ring of the handle is sleeved with a rubber sleeve, and the inner ring of the rubber sleeve is close to the outer surface of the handle.

[0010] By adopting the technical scheme, the rubber sleeve provides a comfortable effect when holding the handle.

[0011] Optionally, both ends of the handle are rotatably connected with the electromagnet through a rotating shaft, and the adsorption block is rotatably connected with the baffle through a rotating shaft.

[0012] By adopting the technical scheme, the position of the upper electromagnet and the adsorption block can be first adsorbed and locked, and then the position of the lower electromagnet and the adsorption block can be adjusted, so that the position of the upper part of the baffle is determined first, and then the angle is determined.

[0013] Optionally, the inner side surface of the electromagnet is fixedly attached with a rubber ring, and the rubber ring is provided with multiple rings.

[0014] By adopting the technical scheme, when the electromagnet is adsorbed and tightly attached to the outer side surface of the side plate, the rubber ring is compressed and deformed to provide better anti-skid effect.

[0015] Optionally, the inner side surface of the magnet block is fixedly attached with a rubber pad.

[0016] By adopting the technical scheme, similarly, when the magnet block is adsorbed and tightly attached to the inner side surface of the side plate, the rubber pad is compressed and deformed to provide better anti-skid effect.

[0017] Compared with the prior art, the technical scheme of the present application has the following advantages:

[0018] 1. The technical scheme of the application can realize adjusting the position of the electromagnet, changing the location of the baffle, the distance from the baffle to the cylinder skin and the inclination angle, and locking the position of the baffle after the electromagnet is powered, so as to accurately adjust the baffle for different ores and meet the requirements of ore dressing.

[0027] The outer side surface of the side plate 1 at the position of the adsorption block 3 is magnetically attracted by the magnet block 7 and is provided with an electromagnet 4, the inner side surface of the electromagnet 4 is fixedly attached with a rubber ring 41, the rubber ring 41 is provided with a plurality of rings, the inner side surface of the magnet block 7 is fixedly attached with a rubber pad 71, and the handle 5 is connected between the electromagnets 4 above and below the same side plate 1, in use, the outer ring of the handle 5 is sleeved and fixed with a rubber sleeve 51, the inner ring of the rubber sleeve 51 is close to the outer surface of the handle 5, the comfort in holding is improved, the synchronous movement of the handle 5 to the positions of the electromagnets 4 above and below can change and adjust the position of the adsorption block 3, and the position of the baffle 2 is adjusted, in order to ensure that the baffle 2 will not slip off during adjustment, the inclination angle of the handle 5 needs to be kept unchanged, and the electromagnets 4 above and below the outer surface of the two side plates 1 are synchronously adjusted, in addition, the rubber ring 41 and the rubber pad 71 are made of rubber material with high hardness, when the electromagnet 4 is not powered and generates a relatively large adsorption force with the magnet block 7, the rubber ring 41 and the rubber pad 71 will not be deformed, when the electromagnet 4 and the magnet block 7 are in contact with the outer surface of the side plate 1, the rubber ring 41 and the rubber pad 71 can be slid to avoid generating a large resistance, only when the rubber ring 41 and the rubber pad 71 are compressed and deformed, a better anti-skid effect can be provided.

[0028] In order to more accurately achieve the above-mentioned purpose of accurate adjustment, the outer side surface of the side plate 1 is provided with a cross grid 11, the cross grid 11 is uniformly distributed on the outer surface of the side plate 1, and the cross grid 11 can provide a relatively accurate position reference during adjustment, so as to facilitate the adjustment of the position of the baffle 2 and the distance between the baffle 2 above and the barrel skin.

[0029] The two ends of the handle 5 are also rotatably connected with the electromagnet 4 through the rotating shaft 6, and the adsorption block 3 is rotatably connected with the baffle 2 through the rotating shaft 6, so that after adjustment, the upper electromagnet 4 can be powered first, with magnetic poles opposite to those of the magnet block 7, and the magnetic attraction between opposite poles is used to press the magnet block 7 in the electromagnet 4 and the adsorption block 3 to tightly contact the two side surfaces of the side plate 1, and the compression spring 33 also compresses the rubber pad 71 and the rubber ring 41 to be pressed against the surface, so that the magnet block 7 in the upper electromagnet 4 and the adsorption block 3 is tightly adsorbed on the surface of the side plate 1, and the adsorption is locked above the baffle 2, the handle 5 can rotate around the electromagnet 4, and the adsorption block 3 can also rotate, so that the position of the lower electromagnet 4 can be adjusted again to adjust the inclination angle of the baffle 2, and the lower electromagnet 4 is powered to adsorb and lock the baffle 2 as a whole, and the baffle 2 is adjusted to the required position and inclination angle.

[0030] When using, if the position, distance or angle of the baffle 2 needs to be adjusted, the electromagnet 4 can be first powered off, and the adsorption block 3 and the electromagnet 4 are attached to the two side surfaces of the side plate 1 by the magnetic attraction force of the magnet block 7. Then two people operate the handle 5 located outside the two side plates 1 at the same time, keep the inclination angle of the handle 5 unchanged, and adjust the position of the electromagnet 4 at both ends of the handle 5 on the X axis synchronously. During the adjustment process, the electromagnet 4 is kept moving on the outer surface of the side plate 1, and then the magnetic attraction force can be used to drive the adsorption block 3 located inside to move, thereby driving the baffle 2 to move position. First, the electromagnet 4 located above is adjusted to position, thereby determining the position and distance of the baffle 2 from the cylinder skin. Then the electromagnet 4 located above is powered on to have magnetic properties opposite to the magnet block 7, and the magnetic attraction force of opposite poles is used to make the electromagnet 4 and the magnet block 7 in the adsorption block 3 tightly attached to the two side surfaces of the side plate 1, and the compression spring 33 also compresses the rubber pad 71 and the rubber ring 41 to make the magnet block 7 in the electromagnet 4 and the adsorption block 3 tightly adsorbed on the surface of the side plate 1. Then the handle 5 can drive the electromagnet 4 below the two side plates 1 to rotate synchronously around the electromagnet 4 above, and the electromagnet 4 below is adjusted to the corresponding position, and the magnetic attraction force is used to drive the adsorption block 3 below to rotate, thereby driving the baffle 2 to rotate around the adsorption block 3 above to adjust the inclination angle of the baffle 2. When adjusting the position of the electromagnet 4 above and below, the position of the electromagnet 4 can be determined and accurately adjusted by the cross grid 11. Finally, the electromagnet 4 below is powered on to have magnetic properties opposite to the magnet block 7, and the magnetic attraction force of opposite poles is used to make the electromagnet 4 and the magnet block 7 in the adsorption block 3 tightly attached to the two side surfaces of the side plate 1, and the compression spring 33 also compresses the rubber pad 71 and the rubber ring 41 to make the magnet block 7 in the electromagnet 4 and the adsorption block 3 tightly adsorbed on the surface of the side plate 1, thereby completing the locking of the baffle 2. During the working process of the magnetic separator, the electromagnet 4 is kept powered on to firmly lock the baffle 2.
