[0002] Crystalline silicon waste is waste generated during the production of crystalline silicon, mainly including waste generated during processes such as crystalline silicon cutting, planing, and polishing. Crystalline silicon waste often contains high-purity silicon materials, which can be reused and recycled to reduce environmental pollution and waste of resources. In the process of handling crystalline silicon waste, improper processes may occur, resulting in excess glue on the outside of the waste. When recycling this part of the crystalline silicon waste, the glue on the outside needs to be removed before it can be recycled;

[0003] Existing devices usually use special detergents to dissolve and remove the glue on the outside of crystalline silicon waste. Direct contact with this type of detergent during use usually causes a certain degree of harm to the workers. However, after a single material is eluted, the workers are required to take out the material before proceeding to subsequent steps. The workers need to contact the material many times during the entire degumming process, and the overall practical effect is poor. Utility Model Content

The threaded ring 33 and the mounting ring 34 are threadedly mounted. When the discharge barrel 31 needs to be installed to the bottom end of the sealing cover 32, it is only necessary to rotate the discharge barrel 31 to a suitable angle and then screw the mounting ring 34 to the outside of the threaded ring 33.

[0024] The discharge barrel 31 is configured as a hollow mesh structure; here, the discharge barrel 31 is configured as a hollow mesh structure so that it can normally contain crystalline silicon waste without affecting the detergent inside the storage barrel 2 from entering the inside of the discharge barrel 31.

[0025] The cleaning control mechanism 4 includes a limit support frame 41 and a drive motor 42. The top outer wall of the sealing cover 32 is provided with a limit support frame 41, and the top outer wall of the limit support frame 41 is provided with a drive motor 42. The drive motor 42 is connected to the top outer wall of the transmission shaft 43, and the side outer wall of the transmission shaft 43 at the bottom is provided with a stirring blade 44; when it is necessary to push the crystalline silicon waste to accelerate its sol speed, it is necessary to control the drive motor 42 to turn on first. Here, the setting of the limit support frame 41 plays an auxiliary supporting role for the drive motor 42. When the drive motor 42 is turned on, it will automatically drive the transmission shaft 43 to rotate and then drive the stirring blade 44 to rotate. As the stirring blade 44 moves along the rotation trajectory, it will automatically drive the crystalline silicon waste to rotate.

[0026] The lifting control mechanism 5 includes a positioning support frame 51, a control motor 52 and a reciprocating screw rod 53. The top outer wall of the support base 1 is provided with a positioning support frame 51, and the top outer wall of the positioning support frame 51 is provided with a control motor 52.

The bottom outer wall of the sealing cover 32 is provided with a resisting snap ring 57. The top outer wall of the storage barrel 2 is provided with a resisting snap groove 58. The resisting snap ring There is a snap-fit ​​installation between 57 and the interference slot 58; when it is necessary to lift the discharge bucket 31 out of the storage bucket 2 in order to dump the contaminated detergent, it is necessary to first control the control motor 52 to turn on. When the control motor 52 is turned on, it will automatically drive the reciprocating screw 53 to rotate and then drive the auxiliary support shaft 54 ​​to rotate. Then the rotation of the reciprocating screw 53 will automatically drive the limit block 55 to move. Here, due to the sliding installation of the protrusions on both sides of the limit block 55 and the inner wall of the side of the positioning support frame 51, the reciprocating screw 53 will only drive the limit block 55 to realize the vertical sliding trajectory movement when rotating. Then the movement of the limit block 55 will automatically drive the mounting plate 56 to move. When the mounting plate 56 moves, it will automatically drive the sealing cover 32 to be lifted and then drive the discharge bucket 31 to be lifted. The setting of the interference clamp ring 57 and the interference slot 58 here facilitates the snap-fit ​​installation of the storage bucket 2 and the sealing cover 32.

[0027] When the utility model is in use, it is necessary to first turn on the control motor 52. When the control motor 52 is turned on, it will automatically drive the reciprocating screw 53 to rotate and then drive the auxiliary support shaft 54 ​​to rotate. Then the reciprocating screw 53 will automatically drive the limit block 55 to move. Here, due to the convex blocks set on both sides of the limit block 55 and the slidable installation of the inner wall of the side of the positioning support frame 51, the reciprocating screw 53 will only drive the limit block 55 to realize the vertical sliding track movement when rotating. Then the movement of the limit block 55 will automatically drive the mounting plate 56 to move. When the mounting plate 5 6 will automatically drive the sealing cover 32 to rise and then drive the discharge barrel 31 to rise when it moves. Then, the discharge barrel 31 is rotated until the mounting ring 34 is separated from the threaded ring 33. Then, a proper amount of crystalline silicon waste is added from the upper end of the discharge barrel 31. After adding, the discharge barrel 31 is rotated to a suitable angle and the mounting ring 34 is screwed to the outside of the threaded ring 33. Then, the control motor 52 is turned on and the above steps are repeated to install the sealing cover 32 above the storage barrel 2. The arrangement of the abutting clamping ring 57 and the abutting clamping groove 58 here facilitates the clamping installation of the storage barrel 2 and the sealing cover 32.

[0028] Then, an appropriate amount of a special detergent for removing the crystalline silicon waste is injected into the storage barrel 2 through the feed pipe at the top of the storage barrel 2. Here, ethanol detergent is used as a reference. If there are other detergents with better effects, they can also be used. After the detergent is added, the drive motor 42 is controlled to start. The setting of the limit support frame 41 here plays an auxiliary supporting effect on the drive motor 42. When the drive motor 42 is turned on, it will automatically drive the transmission shaft 43 to rotate and then drive the stirring blade 44 to rotate. As the stirring blade 44 rotates, it will automatically push the crystalline silicon waste to rotate, and then as the crystalline silicon waste rotates and contacts with the detergent, it will The glue on the outside is gradually dissolved. After a single detergent cleaning is completed, the control motor 52 can be controlled to start and repeat the above steps to lift the discharge barrel 31 to the top of the storage barrel 2 to drain the detergent on the outside of the crystalline silicon waste. Then, the control valve outside the discharge pipe at the bottom of the storage barrel 2 is opened to discharge the contaminated detergent inside the storage barrel 2 through the discharge pipe. After the discharge, the discharge barrel 31 is controlled to continue to be placed inside the storage barrel 2 to replace the detergent with clean water for further cleaning. Please refer to the above steps for details. After the glue of the crystalline silicon waste is taken out, rotate the discharge barrel 31 to remove it from the bottom of the sealing cover 32 and then it can be taken out directly.
