[0015] A method for removing impurities from black mica powder production, comprising the following steps: Step 1: Set the initial state: the collection plate is on one side of the feeding box, and the second sealing plate seals the through groove.

[0016] Step 2: Power on the heating rod and electromagnet.

[0017] Step 3: Start the external motor, make the output shaft of the motor rotate clockwise, pour the black mica powder raw material which needs to be removed from the impurities from the upper end of the feeding box, the motor drives the rotating shaft to rotate, so that the first bevel gear and the rotating rod rotate, and then the second bevel gear drives the rotating rod to rotate, drives the scraper and the sealing frame to rotate, at this time, since the end of the wedge block is provided with a torsional spring, the first circular ring will not rotate, and the second circular ring will also not rotate, and the rotating rod drives the filtering device and the components at the upper end to vibrate up and down.

[0018] Thirdly, when there are many magnetic impurities on the electromagnets, stop the material pouring. At this time, control the motor output shaft to rotate counterclockwise, which will drive the rotating shaft to rotate in reverse, causing the rotating rod to rotate in reverse, which in turn drives the scraper and sealing frame to rotate in reverse. Due to the presence of the wedge, the first ring rotates, which drives the second ring to rotate, causing the gear to rotate, which in turn drives the connecting column to rotate. When the third helical gear rotates, it will drive the fourth helical gear to rotate, which in turn drives the fixed rod to rotate, and finally drives the third guide column to rotate, which in turn drives the reciprocating screw at the end of the third guide column to rotate, causing the collecting plate to slide inward. The eccentric wheel will also rotate, which will cause the eccentric wheel to move forward relative to the guide trigger frame, causing one of the electromagnets to rotate, which in turn causes all the electromagnets to rotate, achieving a 100° rotation. At this time, the collecting plate is below all the electromagnets. Control the motor to stop rotating, and then de-energize the electromagnets after they are energized. The magnetic impurities on the electromagnets will fall onto the collecting plate when the electromagnets are de-energized.

[0019] Fourth, after step three, the collecting plate is filled with magnetic impurities. Then, the motor is restarted, and its output shaft is rotated counter-clockwise. At this time, the collecting plate slowly slides out of the feed hopper. Because the guide trigger frame has a second spring at its front end, as the eccentric wheel rotates, the second spring recovers its elasticity, causing the electromagnet to reverse and return to its initial position. Then, the magnetic impurities on the collecting plate that has slid out of the feed hopper are removed. Fifth, start the motor again, control the output shaft of the motor to rotate clockwise, energize the electromagnet, and then pour the black talc powder raw material that needs to be removed into the feed box from the top again, and repeat this process.

[0020] Beneficial effects: Compared with the prior art, the present invention removes impurities in black talc powder in multiple layers by setting up a two-layer filter device and shaking the filter device, so that the impurity removal effect is better. It also removes and collects iron filings inside the black talc powder. Attached Figure Description

The mesh size of the first filter screen 4 in the first layer is smaller than that of the filter screen 4 in the second layer.

[0025] When the crushed black talc powder is poured into the top filter device 3, due to the presence of the first filter screen, the black talc powder that meets the requirements of the top first filter screen 4 will enter the second layer first filter screen 4, and then enter the discharge cylinder 2, thus completing the removal of impurities from the black talc powder.

[0026] likeFigure 2 As shown in the drawings, in order to accelerate the speed of removing impurities of black talc powder on the first filter screen 4 in the two-layer filter device 3, in this embodiment, a scraper 5 rotating around the center is arranged on the first filter screen 4 in the two-layer filter device, that is, the black talc powder on the first filter screen 4 can flow out of the first filter screen 4 quickly due to the rotation of the scraper 5, and the impurities will be on the inner wall of the filter device 3 due to the rotation of the scraper 5, at this time, the impurities need to be discharged out of the filter device 3, that is, a gap 6 is arranged on the side of the two-layer filter device 3, and a discharging device 7 is arranged at the gap 6, which is used to discharge the impurities.

[0027] As shown in the drawings, Figure 5 In this embodiment, the discharging device 7 includes a bottom plate 8 connected with the gap 6, first sealing plates 9 are arranged on both sides of the bottom plate 8, a second filter screen 11 is further arranged at the front end part of the bottom plate 8, and the second filter screen 11 is communicated with the filter device 3 through a communication groove 12 at the lower end of the second filter screen 11, the first filter screen 4 is between the gap 6 and the communication groove 12, and the second filter screen 11 is arranged to prevent part of the black talc powder from entering the discharging device 7 from the gap 6, so as to avoid waste of raw materials.

[0028] As mentioned above, the scraper 5 needs to be rotated, that is, a rotating rod 13 is arranged through the filter device 3, the rotating rod 13 is fixedly connected with the scraper 5, and the rotating rod 13 is connected with the first filter screen 4 through a bearing, that is, the rotating rod 13 is rotated to rotate the scraper 5.

[0029] As shown in the drawings, Figure 3 and Figure 4 As shown in the drawings, support frames 14 are fixedly arranged on both sides above the base 1, a rotating shaft 15 is arranged through the support frames 14, the rotating shaft 15 is connected with the support frames 14 through a bearing, a motor (not shown in the drawings) is arranged outside the rotating shaft 15, the motor drives the rotating shaft 15 to rotate, a first bevel gear 16 is fixedly arranged at the middle part of the rotating shaft 15, a second bevel gear 17 is fixedly arranged at the bottom of the rotating rod 13, and the first bevel gear 16 and the second bevel gear 17 are gear meshingly connected, that is, the motor is rotated to drive the rotating shaft 15 to rotate, so that the first bevel gear 16 is rotated, then the second bevel gear 17 is rotated, and finally the rotating rod 13 is rotated to drive the scraper 5 to rotate.

[0030] As shown in the drawings, Figure 2 and Figure 4As shown, however, only by the scraper 5 to the first filter screen 4 in the black talc powder impurity, there is a possibility that the black talc powder clog the first filter screen 4, namely in the base 1 upper end are provided with a plurality of first guide column 18, the first guide column 18 outside the sleeve has a first spring 19, one end of the first spring 19 and the base 1 fixedly connected, the other end and the second layer of the filter device 3 bottom connection, in the end of the rotating shaft 15 fixedly provided with a rotating rod 20, the rotating rod 20 end is circular, namely by the rotation of the rotating shaft 15 so that the rotating rod 20 rotates, in turn will drive the filter device 3 to shake, thereby accelerating the filtering speed of black talc powder. It should be noted that the first guide column 18 is telescopic guide column, this technology is prior art, here will not be described in more detail.

[0031] It should be noted that the bottom of the gap 6 is higher than the first filter screen 4, the large particle impurities can cross the gap 6 and the step between the first filter screen 4, thereby entering the bottom plate 8, which is further to prevent entering the bottom plate 8, to avoid waste of materials.

[0032] As shown in Figure 6 and Figure 7 As shown in the embodiment, the upper end of the top filter device 3 is provided with a mounting cylinder 21, and a feeding cylinder 22 is arranged in the mounting cylinder 21. The feeding cylinder 22 is in the shape of a circular truncated cone, and the bottom of the feeding cylinder 22 is connected with the rotating rod 13 through a bearing. A plurality of through grooves 23 are uniformly arranged around the feeding cylinder 22. Correspondingly, a sealing frame 24 is fixedly arranged at the top of the rotating rod 13. A second sealing plate 25 on the sealing frame 24 is used to seal the through grooves 23. That is to say, at the beginning, the second sealing plate 25 seals the through grooves 23, so that the materials in the mounting cylinder 21 cannot flow out. When the rotating rod 13 rotates, the second sealing plate 25 also rotates, so as to open the through grooves 23. The materials flow into the top filter device 3 from the through grooves 23, and then the materials in the filter device 3 are filtered by the scraper 5.

[0033] As shown in Figure 7 As shown in the embodiment, a heating rod 26 is further fixedly arranged at the bottom of the inside of the feeding cylinder 22. The heating rod 26 is powered by an external device, so that the heating rod 26 can heat the materials in the feeding cylinder 22, and then evaporate the moisture in the materials, so as to keep the materials dry, and facilitate the filtration of the materials.

[0034] However, as can be known from common sense, iron filings are common magnetic impurities in black talc powder, which can seriously affect the electrical, magnetic properties and appearance quality of black talc powder, especially in high-end application fields sensitive to magnetic impurities, such as electronic ceramics, precision coatings, etc. The existence of iron filings cannot be ignored.

[0035] As Figure 6 and Figure 9 shown, based on this, the present application solves the above technical problems by the following way: the upper end of the feeding cylinder 22 is provided with a sealing cover 27, the upper end of the sealing cover 27 is fixedly provided with a feeding box 28, the lower end of the feeding box 28 is communicated with the feeding cylinder 22 through the sealing cover 27, a plurality of cylindrical electromagnets 29 are arranged in the feeding box 28, that is, when the electromagnets 29 are energized, the electromagnets 29 generate magnetism, and the magnetic impurities in the material passing through the feeding box 28 are adsorbed, and when the electromagnets 29 are de-energized, the electromagnets 29 lose magnetism, and the adsorbed magnetic impurities will fall off from the electromagnets 29.

[0036] When the impurities adsorbed on the electromagnets 29 are too much, the subsequent adsorption of the magnetic core impurities is not good, so it is necessary to collect the magnetic impurities on the electromagnets 29. Since the electromagnets 29 are inside the feeding box 28, the collecting plate needs to be extended into the inside of the feeding box 28, that is, a chute is arranged on the side of the feeding box 28, a collecting plate 30 is slidably connected in the chute, and baffles are arranged at the end and both sides of the collecting plate 30. That is, when the magnetic impurities on the electromagnets 29 do not need to be collected, the baffles at the end of the collecting plate 30 seal the chute, and when collection is needed, the collecting plate 30 is slid so that the collecting plate 30 is below the electromagnets 29, and then the electromagnets 29 are de-energized. The magnetic impurities on the electromagnets 29 will fall onto the collecting plate 30 due to the de-energization of the electromagnets 29, thereby realizing the function of collecting the magnetic core impurities above the electromagnets 29.

[0037] As Figure 9 and Figure 10 shown, since the material is placed from top to bottom, the upper half of the electromagnets 29 will adsorb a large amount of magnetic core impurities, and when the magnetic impurities on the upper end of the electromagnets 29 are collected, there may be some impurities still on the upper end of the electromagnets 29. Based on this, one end of the electromagnet 29 penetrates the feeding box 28 and is connected with the feeding box 28 through a bearing, chain wheels 31 are fixedly arranged at the end of the electromagnets 29 extending out of one side of the feeding box 28, the chain wheels 31 are connected through chains 32, and the other end is connected with the feeding box 28 through a bearing. That is, by rotating the other end of one of the electromagnets 29, the entire electromagnet 29 can be rotated, so that the side with a large amount of adsorbed magnetic core impurities is rotated to the lower side, and then the electromagnets 29 are de-energized. Due to the loss of magnetic core and gravity, the magnetic impurities will all fall onto the collecting plate 30.

[0038] As Figure 11As shown, one of the electromagnet 29 needs to be rotated, that is, the other end of one of the electromagnet 29 also penetrates the feed tank 28 and is connected with the feed tank 28 through a bearing, a threaded column 33 is fixedly arranged at the end of the electromagnet 29, a guide trigger frame 34 is threadedly connected to the upper end of the threaded column 33, that is, by moving the guide trigger frame 34 forward, the threaded column 33 is rotated, thereby driving the electromagnet 29 to rotate.

The second guide column 36 is a telescopic guide column, which is a prior art and will not be described in detail here.

[0040] As shown in the drawings, Figure 10 As known from the above, the collection plate 30 needs to slide, that is, two ears 38 are arranged on both sides of the feed tank 28, third guide columns 39 are arranged on both sides of the feed tank 28, a reciprocating screw rod 40 is arranged at the front end of one of the third guide columns 39, and the reciprocating screw rod 40 is threadedly connected with the side surface of the collection plate 30, that is, by rotating the third guide column 39, the reciprocating screw rod 40 is rotated, thereby driving the collection plate 30 to slide in the groove.

[0041] As shown in the drawings, Figure 6 , Figure 7 , Figure 8 As known from the above, the guide trigger frame 34 needs to be moved forward and the collection plate 30 also needs to slide, that is, to meet the above-mentioned relationship linkage, the present application adopts the following technical scheme to realize the above-mentioned function, that is, a rotatable connecting column 41 is arranged at the upper end of the feed cylinder 22, an eccentric wheel 10 is fixedly arranged at the end of the connecting column 41, a third bevel gear 42 is fixedly arranged at the middle of the connecting column 41, a fourth bevel gear 43 is arranged in gear engagement with the third bevel gear 42, a fixed rod 44 is fixedly arranged at the end of the fourth bevel gear 43, the fixed rod 44 is connected with the feed tank 28 through a bearing, a driving wheel is arranged on the fixed rod 44, a driven wheel is fixedly arranged at the end of the third guide column 39, and the driving wheel and the driven wheel are connected through a belt.

[0042] When the rotatable connecting column 41 rotates, it will simultaneously drive the third bevel gear 42 and the eccentric wheel 10 to rotate. When the third bevel gear 42 rotates, it will drive the fourth bevel gear 43 to rotate, thereby realizing the rotation of the fixed rod 44, and finally driving the third guide column 39 to rotate, so that the reciprocating lead screw 40 at the end of the third guide column 39 rotates, thereby making the collection plate 30 slide inward. When the eccentric wheel 10 at the upper end rotates, it will make the eccentric wheel 10 move forward to the guide trigger frame 34, thereby making one of the electromagnets 29 rotate, and then making all the electromagnets 29 rotate.

[0043] As described above, the connecting column 41 is rotatable, that is, the connecting column 41 penetrates the upper end of the feeding cylinder 22 and is connected with the feeding cylinder 22 through a bearing. A plurality of fixed devices 45 are arranged in mirror image inside the feeding cylinder 22, which are respectively fixed to the back of the second sealing plate 25 and the inner wall of the mounting cylinder 21. The fixed device 45 includes two fixed connecting frames 46, which are respectively fixedly connected with the back of the second sealing plate 25 and the inner wall of the mounting cylinder 21. A wedge block 47 is slidably connected to one side of the fixed connecting frame 46.

The gear 52 is meshingly connected with the gear ring 51.

[0044] When the rotating rod 13 rotates, it will drive the sealing frame 24 to rotate, thereby making the second sealing plate 25 rotate, and making the fixed device 45 fixedly connected with the second sealing plate 25 rotate, that is, the wedge block 47 on the fixed connecting frame close to the second sealing plate 25 side will rotate, thereby making the first circular ring 48 rotate, driving the second circular ring 50 to rotate, and making the gear 52 rotate, thereby driving the connecting column 41 to rotate.
