[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1-4 As shown, in this embodiment, a device for removing impurities for recycling silicon powder includes: a bottom plate 1;

[0022] A support plate 2 is fixedly mounted on the top of the base plate 1, a mounting plate 3 is slidably mounted on one side of the support plate 2, a roller 4 is rotatably mounted on one side of the inner wall of the mounting plate 3, and a feed port is provided on the roller 4; a closing plate is provided at the feed port.

[0023] A rotating assembly 5 is mounted on the mounting plate 3 and is used to drive the drum 4 to rotate;

[0024] A mounting slot 6 is constructed at one end of the mounting plate 3. A cylindrical plate 7 is rotatably mounted between the two sides of the inner wall of the mounting slot 6. A rotating rod 8 is rotatably inserted into the cylindrical plate 7. The roller 4 is constructed with a through slot. A clamping plate 9 is mounted on the roller 4. The clamping plate 9 engages with the through slot and is rotatably connected to the rotating rod 8. Two electromagnets 18 are symmetrically fixedly mounted on the outer surface of the rotating rod 8. A rotating motor 10 is fixedly mounted on one side of the mounting plate 3. The output end of the rotating motor 10 is fixedly connected to one side of the cylindrical plate 7. A servo motor 11 is fixedly mounted on the cylindrical plate 7. The output end of the servo motor 11 is fixedly connected to one end of the rotating rod 8.

[0025] First, the silicon powder to be processed is introduced into the interior of the drum 4 through the feed port provided on the drum 4. The drum 4 is provided with a clamping plate 9, which is engaged with the through groove of the drum to ensure that the drum 4 is in a closed state.

[0026] The rotating assembly 5 is installed on the mounting plate 3 and is used to drive the drum 4 to rotate. On one side of the drum 4, an electromagnet 18 is installed on the rotating rod 8 to absorb iron-containing impurities in the silicon powder. When the drum 4 rotates, the servo motor 11 drives the rotating rod 8 to rotate accordingly, in the opposite direction of the rotation of the drum 4, to move the silicon powder and use the magnetic adsorption effect of the electromagnet 18 to separate the iron-containing impurities in the silicon powder.

[0027] When it is necessary to clean the iron-containing impurities adsorbed on the electromagnet 18, the motor 10 is rotated to drive the cylindrical plate 7 mounted in the mounting groove 6 to rotate 90 degrees. This action drives the rotating rod 8 to rotate, thereby driving the clamping plate 9 out of the through groove. At this time, the through groove of the drum 4 is opened, and the silicon powder can be discharged from the drum 4 through the through groove, completing the silicon powder cleaning process.

[0028] At the same time, the rotation of the cylindrical plate 7 causes the rotating rod 8 to drive the electromagnet 18 to move vertically out of the drum 4. When the electromagnet 18 moves out of the drum 4 and the power is disconnected, the magnetism of the electromagnet 18 disappears, and the iron-containing impurities adsorbed on it lose their adsorption force, fall down, and are collected for subsequent processing.

[0029] like Figure 2 As shown, the rotating assembly 5 includes a driving motor 51 fixedly mounted on the top of the inner wall of the mounting plate 3, and a gear 52 is fixedly mounted on the output end of the driving motor 51. The outer surfaces of the roller 4 and the clamping plate 9 are provided with a plurality of teeth 53 distributed in an array, and the gear 52 is engaged with the plurality of teeth 53.

[0030] The driving motor 51 is started to drive the gear 52 to rotate. Since the gear 52 is engaged with the plurality of teeth 53, the drum 4 can be driven to rotate.

[0031] like Figure 3 As shown, a plurality of baffles 12 are fixedly mounted on the inner circumference of the drum 4 , and the baffles 12 are distributed in a ring array.

[0032] The main function of these baffles 12 is to effectively disturb and stir the silicon powder inside the drum 4 when it rotates. When the drum 4 rotates, the silicon powder interacts with the baffles 12 under the action of gravity and centrifugal force, and is constantly thrown up and down, which increases the chance of the silicon powder coming into contact with the electromagnet 18, thereby improving the effect of impurity removal. When it is necessary to clean the iron-containing impurities inside the drum 4, the design of the baffles 12 will not hinder the rotation of the card plate 9 and the movement of moving out of the through slot. The silicon powder can be discharged smoothly through the through slot, and the electromagnet 18 can release the adsorbed impurities after power failure for collection and subsequent processing. Such a design makes the entire impurity removal process more efficient and simple, while also reducing the difficulty of maintenance and cleaning.

[0033] like Figure 2 As shown, a limiting plate 13 is fixedly installed on one side of the mounting plate 3, a moving screw rod 14 is installed on one side of the support plate 2, and a lifting motor 15 is fixedly installed on the top of the support plate 2. The output end of the lifting motor 15 is fixedly connected to the top end of the moving screw rod 14, and the moving screw rod 14 is threadedly connected to the limiting plate 13.

[0034] The driving lifting motor 15 drives the moving screw 14 to rotate, thereby driving the limit plate 13 to move up and down along the moving screw 14, and then driving the roller 4 to move up and down. When loading is required, the roller 4 can be moved downward, and then when removing impurities, the roller 4 can be moved upward to avoid the possibility of the rolling roller 4 being touched by the surrounding staff and causing injury.

[0035] like Figure 2 As shown, a collecting frame 16 is placed on the top of the bottom plate 1 , and a partition plate 17 is fixedly installed between the two sides of the inner wall of the collecting frame 16 .

[0036] The partition plate 17 divides the collecting frame 16 into two areas for collecting silicon powder and iron-containing impurities respectively. The area for collecting iron-containing impurities is located just below the removed electromagnet 18.

[0037] like Figure 2 As shown, the inner circumference of the drum 4 is configured with a cambered surface.

[0038] The setting of the arc surface avoids silicon powder residue in the dead corner of the roller 4, which causes waste and troubles in subsequent processing.

[0039] The utility model provides a device for removing impurities from recycled silicon powder. The specific working principle is as follows:

[0040] First, the silicon powder to be processed is introduced into the inside of the drum 4 through the feed port set on the drum 4, and the drive motor 51 is started to drive the gear 52 to rotate. Since the gear 52 is engaged with the multiple teeth 53, the drum 4 can be driven to rotate. When the drum 4 rotates, the servo motor 11 drives the rotating rod 8 to rotate accordingly, which is opposite to the direction of rotation of the drum 4. Under the action of gravity and centrifugal force, the silicon powder interacts with the baffle 12 and is continuously thrown up and down, increasing the chance of contact between the silicon powder and the electromagnet 18, thereby improving the impurity removal effect, and moving the silicon powder and utilizing the magnetic adsorption effect of the electromagnet 18 to separate the iron-containing impurities in the silicon powder. When it is necessary to clean the iron-containing impurities adsorbed on the electromagnet 18, the cylindrical plate 7 installed in the mounting groove 6 is driven by the rotating motor 10 to rotate 90 degrees. This action will drive the rotating rod 8 to rotate, thereby driving the clamping plate 9 to move out of the through slot. At this time, the through slot of the drum 4 is opened, and the silicon powder can be discharged from the outside of the drum 4 through the through slot, completing the cleaning of the silicon powder. At the same time, the rotation of the cylindrical plate 7 will also cause the rotating rod 8 to drive the electromagnet 18 to move vertically out of the drum 4. The electromagnet 18 moves out of the drum 4 and the power is disconnected. The magnetism of the electromagnet 18 disappears, and the iron-containing impurities adsorbed on it will lose their adsorption force, thereby falling and being collected for subsequent processing.

[0041] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
