Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1-3 The utility model provides an embodiment: a magnetic separator for processing silicon micropowder, comprising a box body 1, a movable plate 11 is slidably connected to the middle of the box body 1, two lead screws 3 are rotatably connected to the top of the box body 1, a servo motor 2 is fixedly connected to the left side of the box body 1, one end of one lead screw 3 is fixedly connected to the output end of the servo motor 2, a connecting assembly is installed at the periphery of the two lead screws 3, the connecting assembly comprises two pulleys 12, the two pulleys 12 are respectively fixedly connected to the periphery of the two lead screws 3, and a synchronous belt 13 is sleeved on the periphery of the two pulleys 12.

[0026] When in use, the servo motor 2 is driven to rotate a lead screw 3, and the lead screw 3 drives the pulley 12 to rotate together. The pulley 12 drives the pulley 12 on the outer periphery of another lead screw 3 to rotate together through the synchronous belt 13, so that the two lead screws 3 can rotate together.

[0027] The outer circumferences of the two lead screws 3 are threadedly connected to a threaded plate 4, the bottom of the threaded plate 4 is fixedly connected to a shell 5, the bottom of the shell 5 is fixedly connected to a comb tooth 17, the middle of the shell 5 is slidably connected to two permanent magnets 18, the outer sides of the two permanent magnets 18 are fixedly connected to positioning blocks 20, a positioning groove 21 is opened in the middle of the shell 5, the positioning block 20 is slidably connected to the middle of the positioning groove 21, and the tops of the two permanent magnets 18 are fixedly connected to a pull rod 19.

[0028] When in use, the screw 3 rotates to drive the threaded plate 4 to move back and forth, so that the threaded plate 4 can drive the shell 5 to move together, so that the shell 5 can drive the comb teeth 17 to move the silicon micropowder on the top of the movable plate 11, so that the permanent magnet 18 in the middle of the shell 5 can absorb the iron filings in the silicon micropowder, and after a long period of adsorption, the permanent magnet 18 can be taken out from the middle of the shell 5 by the pull rod 19, so as to clean the iron filings adsorbed on the permanent magnet 18, and at the same time, under the action of the positioning block 20 and the positioning groove 21, the permanent magnet 18 can be clamped in the middle of the shell 5, so as to quickly install the permanent magnet 18, thereby improving the working efficiency of the magnetic separator.

[0029] Reference Figure 1 , 3 and 5, a baffle 7 is slidably connected to the middle of the box body 1, and sliders 26 are fixedly connected to the front and rear sides of the baffle 7, a slide groove 25 is opened in the middle of the box body 1, and the slider 26 is slidably connected to the middle of the slide groove 25, and the bottom of the box body 1 is rotatably connected to two support rods 14, and the bottom of the box body 1 is fixedly connected to two connecting rings 30, and the middle parts of the two connecting rings 30 are slidably connected to a slide rod 31, and the outer periphery of the slide rod 31 is rotatably connected to two telescopic rods 15, and the middle parts of the two telescopic rods 15 are fixedly connected to a cross bar 16, and the top of the cross bar 16 is fixedly connected to an electric push rod 29, and the other end of the electric push rod 29 is rotatably connected to the outer periphery of the slide rod 31.

[0030] During use, after the iron filings in the silicon micropowder are adsorbed, the baffle 7 is pulled out from the middle of the box body 1, and then the electric push rod 29 is driven to push the slide bar 31 to move upward. While the slide bar 31 moves upward, it will pull the telescopic rod 15 to extend and retract. At the same time, the slide bar 31 will push the connecting ring 30 upward, so that the connecting ring 30 pushes the box body 1 to tilt, thereby discharging the silicon micropowder on the top of the movable plate 11 from the middle of the box body 1, so as to facilitate the collection of the silicon micropowder. At the same time, when the slide bar 31 pushes the connecting ring 30, it will slide in the middle of the connecting ring 30, so that the box body 1 can be pushed smoothly.

[0031] Reference Figure 1 and 4A fixed plate 8 is fixedly connected to the front side of the box body 1, a rotating motor 9 is fixedly connected to the top of the fixed plate 8, a rotating plate 10 is fixedly connected to the output end of the rotating motor 9, a round rod 6 is fixedly connected to the top of the rotating plate 10, a collar 22 is sleeved on the outer periphery of the round rod 6, a blocking block 24 is fixedly connected to the top of the round rod 6, a connecting rod 23 is fixedly connected to the outer side of the collar 22, the other end of the connecting rod 23 is rotatably connected to the outer side of the movable plate 11, and the left and right sides of the movable plate 11 are fixedly connected to limiting blocks 28, a limiting groove 27 is provided in the middle of the box body 1, and the limiting block 28 is slidably connected to the middle of the limiting groove 27.

[0032] When in use, the rotating motor 9 is fixedly supported by the fixed plate 8, and the rotating motor 9 is driven to drive the rotating plate 10 to rotate, so that the rotating plate 10 drives the round rod 6 to rotate, so that the round rod 6 pushes or pulls the ring 22, and the ring 22 simultaneously pushes or pulls the connecting rod 23, so that the connecting rod 23 can push or pull the movable plate 11 to shake quickly in the middle of the box body 1, and under the action of the limit block 28 and the limit groove 27, the stability of the movable plate 11 during shaking is improved, so that the silicon micropowder can be fully moved by the comb teeth 17 under the shaking of the movable plate 11, thereby improving the adsorption effect of the permanent magnet 18 on the iron filings in the silicon micropowder.

[0033] Working principle: drive the servo motor 2 to drive the lead screw 3 to rotate. Under the connection between the pulley 12 and the synchronous belt 13, the two lead screws 3 rotate together, so that the threaded plate 4 can reciprocate on the outer periphery of the lead screw 3. At the same time, the threaded plate 4 drives the shell 5 to move. The three rows of comb teeth 17 at the bottom of the shell 5 can move the silicon micropowder on the top of the movable plate 11, so that the permanent magnet 18 between the three rows of comb teeth 17 can adsorb the iron filings in the silicon micropowder. After a long period of adsorption, the permanent magnet 18 can be taken out from the middle of the shell 5 by the pull rod 19 for cleaning. At the same time, the permanent magnet 18 can be clamped in the middle of the shell 5 under the action of the positioning block 20 and the positioning groove 21, so that the permanent magnet 18 can be quickly installed.

[0034] The rotating motor 9 is driven to drive the rotating plate 10 to rotate, so that the rotating plate 10 drives the round rod 6 to rotate together, so that the round rod 6 can push and pull the ring 22. The ring 22 will drive the connecting rod 23 to move while being pushed and pulled, so that the connecting rod 23 can quickly push and pull the movable plate 11 to shake in the middle of the box body 1, so that the silicon micropowder can be more dispersed by the comb teeth 17 under the shaking of the movable plate 11, thereby improving the adsorption effect of the permanent magnet 18 on the iron filings in the silicon micropowder.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
