Description

Technical Field

[0001] This utility model relates to the field of material separation equipment technology, and in particular to a copper-containing silicon powder processing system. Background Technology

[0002] Copper-containing silicon powder processing equipment is a specialized set of equipment designed for the efficient separation, purification, and recovery of copper and silicon powder mixed waste generated in industrial production. It utilizes physical separation (such as screening and centrifugation) and chemical purification (such as acid leaching) processes to achieve this. Integrating vibrating screens, centrifuges, and reaction vessels, it can process byproducts from the photovoltaic and electronics industries, reducing solid waste pollution and achieving resource recycling. It falls under the category of resource recycling and environmental protection equipment.

[0003] When processing copper-containing silicon powder, existing equipment suffers from the problem that moist silicon powder is prone to agglomeration. The existing equipment lacks a structure to break up the agglomerated material, resulting in large, undispersed impurities mixing with the useful material. This increases the difficulty of subsequent purification, reduces the purity of the final product, and affects the resource recovery value. Furthermore, existing equipment struggles to remove magnetic impurities from copper-containing silicon powder. Failure to separate magnetic impurities leads to the introduction of magnetic substances into the final recovered copper material, reducing the purity of the copper and the recovery efficiency, while also increasing the complexity and cost of subsequent purification processes.

The diameter of the pulley 13 is larger than that of the drive wheel 12, and the same belt 20 is wound between the drive wheel 12 and the pulley 13.

[0028] In this embodiment, a motor slot is provided inside the feeding base 1, and a servo motor 11 is fixedly installed on the bottom inner wall of the motor slot. The output shaft of the servo motor 11 is fixedly connected to the drive wheel 12, so that the servo motor 11 can drive the drive wheel 12 to rotate.

[0029] In this embodiment, a conveying shaft 14 is rotatably mounted on one inner wall of the magnetic separator 3. The other end of the conveying shaft 14 extends out of the magnetic separator 3. The end of the conveying shaft 14 extending out of the magnetic separator 3 rotatably passes through the feed base 1 and is fixedly connected to the pulley 13.

[0030] In this embodiment, the surface of the part of the conveying shaft 14 located in the feed trough is provided with four feed ports 15, the surface of the part of the conveying shaft 14 located in the magnetic separator 3 is provided with four discharge ports 16, the inside of the conveying shaft 14 is provided with a conveying chamber, and the four feed ports 15 and the four discharge ports 16 are connected to the same conveying chamber.

[0031] In this embodiment, multiple guide strips 17 are fixedly installed on the inner wall of the material conveying chamber to facilitate the movement of materials.

The scraper ring 18 is slidably installed on the inner side of the magnetic separation cylinder 3. The electric push rod 19 is fixedly installed on the top of the auxiliary base 2.

[0033] Working Principle: When processing copper-containing silicon powder, the operator pours the material into the dispersing hopper 6 and starts the equipment. The dual-shaft motor 9 starts, driving the two eccentric blocks 10 to rotate. The rotation of the two eccentric blocks 10 generates inertia, causing the screen 7 to vibrate. The vibration of the screen 7 disperses the material on it. The dispersed material falls through the screen 7 into the feed base 1. At the same time, the servo motor 11 starts, driving the drive wheel 12 to rotate. The drive wheel 12 drives the pulley 13 to rotate via the belt 20. The rotation of the pulley 13 drives the conveyor shaft 14 to rotate. The material enters the conveying chamber through the four feed ports 15 on the surface of the conveyor shaft 14. The material is then guided by multiple guide bars 17 along the conveyor shaft 14. The material moves axially to the other end of the conveyor shaft 14 and is discharged through four discharge ports 16. The material falls onto the inner wall of the magnetic separator 3. The surface of the magnetic separator 3 is equipped with annular permanent magnets 4. When the material passes through the magnetic separator 3, the magnetic copper particles are adsorbed onto the inner wall surface of the magnetic separator 3, while the non-magnetic silicon powder is discharged directly through the output port at the bottom of the magnetic separator 3 under the action of gravity. The electric push rod 19 is activated intermittently, which drives the scraper ring 18 to move. The movement of the scraper ring 18 scrapes away the magnetic impurities adsorbed on the inner wall surface of the magnetic separator 3. The magnetic impurities move with the scraper ring 18 and are discharged through the magnetic powder port, completing the magnetic separation and facilitating the subsequent processing of the copper-containing silicon powder.

[0034] The technological advancements of this invention compared to existing technologies are as follows: it can drive the screen 7 to vibrate, breaking up agglomerated copper-containing silicon powder, reducing purification difficulty, thereby improving product purity and resource recycling value. Furthermore, through the magnetic separation mechanism, it can separate magnetic impurities in the silicon powder, simplifying subsequent processes, eliminating the need for additional treatment of magnetic impurities, reducing purification difficulty, improving overall processing efficiency, and greatly enhancing work efficiency.
