Description

Technical Field

[0001] This utility model relates to the field of purification and pretreatment technology of high-silicon powder from solid waste, specifically a purification and pretreatment device for high-silicon powder from silicon-based industrial solid waste. Background Technology

[0002] Silicon-based industry refers to the industrial system formed based on silicon materials. It is the core of the modern electronics industry and is widely used in fields such as computers, communications, consumer electronics, automotive electronics, and new energy. In the process of silicon-based industrial production and manufacturing, a certain amount of solid waste high-silicon powder is generated. Solid waste high-silicon powder refers to solid waste powder with a high silicon content, mainly including ferrosilicon alloy waste, wollastonite waste, and quartz waste.

[0003] With the increasing awareness of environmental protection and the development of resource recycling technology, the recycling of high-silicon powder from solid waste is very important. Before purifying silicon-based industrial solid waste, it is generally necessary to pre-treat the silicon-based industrial solid waste to form powder, which facilitates the subsequent purification of the silicon-based industrial solid waste. This requires the use of purification pre-treatment equipment.

[0004] For example, the silicon-based industrial solid waste high-silicon powder purification and pretreatment device proposed in publication number CN217663576U uses the silicon-based industrial solid waste powder to be crushed by the rotation of two crushing rollers. After crushing, the silicon-based industrial solid waste powder is formed into fine powder, which is discharged into the bottom of the treatment box by the filter plate under the action of the guide block. However, after the high-silicon powder is crushed, some impurities and pollutants are still likely to exist on its surface. If cleaning is inconvenient, it will still directly affect the pretreatment effect of the high-silicon powder. Utility Model Content

[0005] The purpose of this invention is to provide a purification and pretreatment device for high-silicon powder from silicon-based industrial solid waste, in order to solve the problem mentioned in the background art that after the high-silicon powder from solid waste is crushed, some impurities and contaminants are still easily present on its surface, which, if not easily cleaned, can directly affect the pretreatment effect of the high-silicon powder from solid waste.

A slag discharge port is installed at the lower right side of the washing tank. Support plates are fixed to both sides of the inner wall of the washing tank. A positioning column is fixed to the top of the support plate. A filter plate is mounted above the support plate, and a settling groove is formed in the top of the filter plate. A locking nut is connected to the upper outer position of the positioning column. Positioning holes are opened on both sides of the filter plate. A spray pipe is mounted on the back of the washing tank using a mounting frame. A spray head is installed on the front end of the spray pipe. A solution tank is installed on the left side of the top of the bottom plate. A first motor is installed on the left side of the solution tank. A stirring rod is connected to the output end of the first motor. A liquid inlet is installed on the left side of the top of the solution tank. A pump body is mounted on the right side of the top of the solution tank. One end of the pump body is connected to a first drain pipe, and the other end of the pump body is connected to a second drain pipe.

[0007] As a further technical solution of this utility model, the tail end of the first drainage tube is connected to the back end of the solution tank and is interconnected with it, and the side tail end of the second drainage tube is interconnected with the interior of the spray tube.

[0009] As a further technical solution of this utility model, the support plate is symmetrically distributed about the central axis of the cleaning pool, and the positioning column and the locking nut form a threaded connection.

[0010] As a further technical solution of this utility model, a feed inlet is installed on the top of the crushing box, a third motor is installed at the back end of the crushing box, the output end of the third motor is connected to a crushing roller, and crushing teeth are uniformly fixed on the outer side wall of the crushing roller.

[0011] As a further technical solution of this utility model, the bottom of the crushing box is connected to a guide pipe, the bottom of the guide pipe is connected to the top of the feeding box, a second motor is installed on the side of the feeding box, the output end of the second motor is connected to a spiral conveying rod, and a discharge port is connected to the right side of the bottom of the feeding box. The discharge port is located directly above the washing pool and its diameter is smaller than that of the filter plate.

[0012] As a further technical solution of this utility model, an arc-shaped plate is fixed at the front and rear positions of the inner wall of the liquid inlet, a filter cotton sheet is laid on the top of the arc-shaped plate, a hollow pressure ring is provided on the top of the filter cotton sheet, and a connecting bolt is fixed between the arc-shaped plate and the hollow pressure ring.

[0013] As a further technical solution of this utility model, the arc-shaped plates are symmetrically distributed about the central axis of the liquid inlet, and the connecting bolts are evenly distributed between the arc-shaped plates and the hollow pressure ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the purification and pretreatment device for silicon-based industrial solid waste high silicon powder not only improves the cleaning effect, but also improves the solution filtration capacity and crushing capacity of the purification and pretreatment device.

[0015] By installing the solution tank on the top left side of the base plate, fixing the support plate on both sides of the inner wall of the cleaning tank, and assembling the filter plate on top of the support plate, the positioning column can be positioned through the positioning hole and then locked with the locking nut, forming a sinking trough in the top of the filter plate. Therefore, when discharging from the outlet, the material can fall vertically into the sinking trough. Then, the pump is started, and the solution in the solution tank is drawn out through the first drainage pipe, then discharged through the second drainage pipe to the spray pipe, and finally sprayed evenly at the spray head to achieve the cleaning purpose. The residue and waste liquid can be discharged at the slag discharge port. This improves the overall cleaning effect during the operation.

[0016] By installing the inlet on the top left side of the solution tank and fixing an arc-shaped plate at the front and rear positions of the inner wall of the inlet, placing the filter cotton sheet above the arc-shaped plate, and then pressing the hollow pressure ring above the filter cotton sheet, the connection between the arc-shaped plate and the hollow pressure ring is completed using a connecting bolt. In this way, the solution can be filtered and enter the solution tank during operation, thereby improving the overall filtration capacity.

[0017] By mounting the third motor on the back of the crushing box, the crushing rollers can be driven to rotate after the third motor is working. The material is then crushed by the external crushing teeth after the two crushing rollers rotate. The guide pipe is connected to the feeding box, so the crushed material can be guided into the inside of the feeding box. Then, the second motor is started to drive the spiral conveyor rod to rotate, so as to achieve the purpose of feeding. This not only improves the crushing effect, but also improves the feeding effect. Attached Figure Description
