Description

Technical Field

[0001] This utility model relates to the field of silicon powder processing technology, specifically to an iron removal mechanism used in silicon powder screening. Background Technology

[0002] Silicon powder, also known as silica micron powder, is a very fine powdery substance, usually made from high-purity silicon materials such as silicon trioxide or silicon tetroxide. During its production and processing, after the raw material is crushed, screening equipment is used to assist in screening and removing impurities inside the silicon powder. Since silicon material itself contains a certain amount of iron, and in order to reduce the impact of iron powder on the overall performance of silicon powder, an iron removal mechanism is also needed during the screening process to remove iron powder from the inside of the processed silicon powder.

[0003] According to the iron removal device for silicon powder processing disclosed in application number CN202122567074.1, which is easy to maintain, the iron removal mechanism has high iron removal efficiency, can adsorb and collect more iron powder, and can run for a longer time each time it is turned on, which greatly improves the iron removal efficiency of silicon powder.

[0004] However, when the above-mentioned iron removal device is used to remove iron powder from the inside of the sieved silicon powder, the number of adsorption iron removal components inside the device is limited, resulting in limited adsorption removal capacity. When the amount of silicon powder is large, the removal effect of iron powder impurities inside the silicon powder is poor, which is insufficient and not convenient for efficient removal of iron powder impurities inside the sieved silicon powder.

[0005] Now, a novel iron removal mechanism for silicon powder screening is proposed to address the above-mentioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide an iron removal mechanism for silicon powder sieving, so as to solve the problem mentioned in the background art of the inconvenience of efficiently removing iron powder impurities inside the sieved silicon powder.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an iron removal mechanism for silicon powder screening, comprising a screening box and a frame. Slots are respectively opened inside both sides of the screening box, and the frame is inserted into the slots. A roller magnet is horizontally arranged at the front end of the frame, and a roller magnet is horizontally arranged at the rear end of the frame. A connector is fixed to the left side of the roller magnet and the roller magnet, and a connector is fixed to the right side of the roller magnet and the roller magnet. The right side of the connector penetrates the interior of the right side of the frame and is fixed with a gear. A side frame is fixed to the right side of the frame, and a reducer is installed and fixed at the front end of the right side of the side frame. A drive motor is installed and fixed to the right side of the reducer, and the output shaft of the reducer penetrates the interior of the right side of the side frame and is fixed with a gear.

[0008] As a further technical solution of this utility model, the left side of the connector head one penetrates the interior of the left side of the frame, and the roller magnet one and roller magnet two are respectively laterally movably connected inside the frame.

[0009] As a further technical solution of this utility model, the output shaft of the drive motor is fixedly connected to the input shaft of the reducer, the third gear is meshed with the first gear, and the first gear is meshed with the second gear.

[0010] As a further technical solution of this utility model, scraper rings are respectively sleeved on both sides of the outer side of the first roller magnet and the second roller magnet. Electric push rods are respectively installed and fixed at both ends of the top of both sides of the frame. Mounting seats are respectively provided on both sides of the top of the first roller magnet and the second roller magnet. Screws are respectively fixed at both ends of the top of the scraper ring. Nuts are respectively provided at both ends of the top of the mounting seat. The output end of the electric push rod passes through the interior of one side of the frame and is fixedly connected to one side of the mounting seat. The electric push rod, the mounting seat and the scraper ring are respectively symmetrically arranged about the vertical center line of the frame.

[0011] As a further technical solution of this utility model, the top end of the screw rod penetrates the interior of the top end of the mounting base, and the nut is threadedly rotatably connected to the outside of the screw rod.

[0012] As a further technical solution of this utility model, a side plate 1 is provided at the bottom left side of the screening box, and a side plate 2 is provided at the bottom right side of the screening box. Inner holes are respectively opened at both ends of the bottom left side of the side plate 1 and the bottom right side of the side plate 2. Screws 2 are respectively fixed at both ends of the bottom sides of the screening box, and nuts 2 are respectively provided on the left side of the side plate 1 and the right side of the side plate 2.

[0013] As a further technical solution of this utility model, the second screw penetrates the interior of the inner hole, and the second nut is threadedly rotatably connected to the outside of the second screw.

[0014] As a further technical solution of this utility model, the top of the screening box is fixed with a feed inlet and the bottom of the screening box is fixed with a discharge outlet.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the iron removal mechanism used in the silicon powder screening not only realizes the efficient removal of iron powder impurities inside the silicon powder after screening, and facilitates the auxiliary cleaning of the iron powder adsorbed in the mechanism, but also makes it easy to disassemble and assemble the iron removal mechanism.

[0016] The iron removal mechanism is installed inside the screening box by setting up a frame, screening box, connector 1, roller magnet 1, connector 2, gear 1, roller magnet 2, gear 2, side frame, drive motor, reducer, and gear 3. When removing iron from the screened silicon powder, the drive motor can be started to drive gear 3 to rotate using the reducer.

After the silicon powder is screened by the screening components at the top of the screening box, the qualified silicon powder will fall down onto the frame. The two sets of adsorption components, roller magnet 1 and roller magnet 2, can increase the adsorption capacity of the mechanism. When the silicon powder passes through roller magnet 1 and roller magnet 2, some iron powder impurities inside can be quickly adsorbed and attached to the outside of roller magnet 1 and roller magnet 2. The silicon powder after iron removal falls from the inside of the mechanism to the bottom of the screening box and can be discharged from the discharge port, which facilitates efficient removal of iron powder impurities inside the screened silicon powder.

[0017] By setting up a frame, electric push rod, mounting base, roller magnet one, scraper ring, roller magnet two, screw one, and nut one, the iron removal mechanism can remove iron powder from silicon powder. After the iron powder is adsorbed on the outside of roller magnet one and roller magnet two, the electric push rods on both sides can be started periodically. The output end extends and drives the scraper ring to move inward on the outside of roller magnet one and roller magnet two. This can also help clean some of the iron powder adsorbed on the outside. After cleaning, the removal operation can be repeated.

[0018] The iron removal mechanism is equipped with a screening box, side plate one, frame, slot, side plate two, nut two, screw two, and inner hole. When installing and using it, the frame can be inserted into the corresponding slot on the right side of the screening box, penetrating the interior of the screening box. Then, side plate one and side plate two can be inserted into the outside of screw two through the inner hole at the bottom of both sides of the screening box. After screwing nut two into the outside of screw two, side plate one and side plate two can be fixedly installed on both sides of the screening box. The side plate one and side plate two can be used to assist in locking and limiting the frame inside the slot. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides an embodiment of an iron removal mechanism for silicon powder screening, including a screening box 1 and a frame 3. Slots 8 are respectively opened inside both sides of the screening box 1, and the frame 3 is inserted into the slots 8. A roller magnet 7 is horizontally arranged at the front end inside the frame 3, and a roller magnet 12 is horizontally arranged at the rear end inside the frame 3. A connector 5 is fixed to the left side of the roller magnet 7 and the roller magnet 12, and a connector 9 is fixed to the right side of the roller magnet 7 and the roller magnet 12. The right side of the connector 9 passes through the inside of the right side of the frame 3 and is fixed with a gear 13. A side frame 14 is fixed to the right side of the frame 3, and a reducer 16 is installed and fixed at the front end of the right side of the side frame 14. A drive motor 15 is installed and fixed to the right side of the reducer 16, and the output shaft of the reducer 16 passes through the inside of the right side of the side frame 14 and is fixed with a gear 17.

[0027] The left side of connector 15 penetrates the interior of the left side of frame 3. Roller magnet 17 and roller magnet 212 are movably connected laterally inside frame 3. The output shaft of drive motor 15 is fixedly connected to the input shaft of reducer 16. Gear 317 is meshed with gear 10, and gear 10 is meshed with gear 213.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the controllable drive motor 15 starts and drives the gear 17 to rotate using the reducer 16. While the gear 17 rotates, the meshing gears 10 and 23 drive the roller magnets 7 and 2 to rotate simultaneously. After the silicon powder is screened by the screening component at the top of the screening box 1, the qualified silicon powder will fall down onto the frame 3. The two sets of adsorption components, roller magnets 7 and 2, can increase the adsorption capacity of the mechanism. When the silicon powder passes through roller magnets 7 and 2, some iron powder impurities inside can be quickly drawn out and attached to the outside of roller magnets 7 and 2. After the iron powder is removed, the silicon powder falls from the inside of the mechanism to the bottom of the screening box 1 and can be discharged from the discharge port 25, thus efficiently removing the iron powder impurities inside the screened silicon powder.

[0029] Scraper rings 11 are respectively sleeved on both sides of the outer sides of roller magnet 17 and roller magnet 212. Electric push rods 4 are respectively installed and fixed at both ends of the top of both sides of the frame 3. Mounting seats 6 are respectively provided on both sides of the top of roller magnet 17 and roller magnet 212. Screws 18 are respectively fixed at both ends of the top of scraper ring 11. Nuts 19 are respectively provided at both ends of the top of mounting seat 6. The output end of electric push rod 4 passes through the interior of one side of the frame 3 and is fixedly connected to one side of mounting seat 6. Electric push rod 4, mounting seat 6 and scraper ring 11 are symmetrically arranged about the vertical center line of frame 3. The top end of screw 18 passes through the interior of the top of mounting seat 6. Nut 19 is threadedly rotatably connected to the outside of screw 18.

[0030] Specifically, such as Figures 1-3 As shown, the electric push rods 4 on both sides can be started periodically. When the output end extends, it can drive the scraper ring 11 to move inward from the outside of the roller magnet 7 and the roller magnet 12, and can assist in cleaning some iron powder adsorbed on the outside.

[0031] A side plate 1 2 is provided at the bottom left side of the screening box 1, and a side plate 20 is provided at the bottom right side of the screening box 1. Inner holes 23 are respectively provided at both ends of the bottom left side of the side plate 1 2 and the bottom right side of the side plate 20. Screws 22 are respectively fixed at both ends of the bottom of both sides of the screening box 1. Nuts 21 are respectively provided on the left side of the side plate 1 2 and the right side of the side plate 20. The screws 22 penetrate the interior of the inner holes 23, and the nuts 21 are threadedly connected to the outside of the screws 22.

[0032] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, when installing and using the mechanism, the frame 3 can be inserted into the slot 8 corresponding to the right side of the screening box 1, and then inserted through the internal holes 23 of the side plates 2 and 20 at the bottom of both sides of the screening box 1, respectively, into the outside of the screw 22. After screwing the nut 21 into the outside of the screw 22, the side plates 2 and 20 can be fixedly installed on both sides of the screening box 1. The side plates 2 and 20 can be used to assist in locking and limiting the frame 3 inside the slot 8. When disassembling the iron removal mechanism, the side plates 2 and 20 can be removed, and the mechanism can be quickly pulled out and disassembled from the inside of the screening box 1.

[0033] The top of the screening box 1 is fixed with a feed inlet 24, and the bottom of the screening box 1 is fixed with a discharge outlet 25.

[0034] Working Principle: When installing and using this iron removal mechanism, the frame 3 can be inserted into the corresponding slot 8 on the right side of the screening box 1, penetrating the interior of the screening box 1. Then, side plates 1 2 and 20 can be inserted into the outside of screw 22 through the internal holes 23 at the bottom positions on both sides of the screening box 1, and nuts 21 can be screwed into the outside of screw 22. This fixes side plates 1 2 and 20 on both sides of the screening box 1, providing auxiliary locking and limiting for the frame 3. The iron removal mechanism is installed inside the screening box 1. When removing iron from the screened silicon powder, the drive motor 15 can be started, and the reducer 16 drives gear 3 17 to rotate. The rotation of gear 3 17 simultaneously drives roller magnet 1 7 and roller magnet 2 12 to rotate through meshing gears 1 10 and 2 13. The silicon powder passes through... After screening by the screening component at the top of the screening box 1, the qualified silicon powder will fall downwards onto the frame 3. The adsorption capacity of the mechanism can be increased by the two sets of adsorption components, roller magnet 1 7 and roller magnet 2 12. When the silicon powder passes through roller magnet 1 7 and roller magnet 2 12, some iron powder impurities inside can be quickly adsorbed and attached to the outside of roller magnet 1 7 and roller magnet 2 12. After the iron powder is removed, the silicon powder falls from the inside of the mechanism to the bottom of the screening box 1 and can be discharged from the discharge port 25. After the iron powder in the silicon powder is adsorbed on the outside of roller magnet 1 7 and roller magnet 2 12, the electric push rods 4 on both sides can be started periodically. The output end extends and drives the scraper ring 11 to move inward on the outside of roller magnet 1 7 and roller magnet 2 12, which can assist in cleaning some iron powder adsorbed on the outside. After cleaning, the removal operation is repeated.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
