Description
Technical Field
The invention relates to the technical field of powdery material processing, in particular to a classifying device for powdery materials.
Background
The silicon chip is the main production material in the semiconductor and photovoltaic fields, the silicon chip multi-wire cutting technology is the current more advanced silicon chip processing technology in the world, and is different from the traditional cutting modes such as a knife saw blade, a grinding wheel and the like, and also different from the advanced laser cutting and inner circle cutting, the principle is that a steel wire moving at a high speed drives cutting fluid attached to a steel wire to rub a silicon rod, so that the cutting effect is achieved, in the whole process, the steel wire is guided by a wire roller, a wire net is formed on the wire roller, and a workpiece to be processed is fed by the lowering of a workbench. Compared with other technologies, the silicon wafer multi-wire cutting technology has the advantages of high efficiency, high productivity, high precision and the like, so that the multi-wire cutting technology is the most extensive silicon wafer cutting technology at present.
In the multi-wire cutting technology, the cutting fluid is generally prepared from polyethylene glycol and silicon carbide particles with about 1200 meshes according to a certain proportion, the cutting fluid is inevitably mixed with silicon powder cut in the process of cutting a silicon rod to form a large amount of cutting waste liquid, and part of the silicon carbide particles in the cutting fluid are damaged due to the cutting action, so that the meshes of part of silicon carbide are increased, and therefore, the cutting waste liquid cannot be directly reused. The waste cutting liquid contains a lot of resources such as silicon carbide, silicon powder and the like, and if the waste cutting liquid is directly discharged, the waste cutting liquid not only wastes the resources, but also pollutes the environment, so the disposal of the waste cutting liquid is always a difficult problem in the photovoltaic industry.
At present, the following methods are generally adopted for the treatment of cutting waste liquid: firstly, performing solid-liquid separation on cutting waste liquid, namely separating polyethylene glycol liquid from silicon carbide particles and silicon powder particles in the cutting waste liquid to obtain polyethylene glycol liquid and silicon carbide solid mixed with silicon powder, wherein the separated polyethylene glycol liquid can be used as a raw material to prepare cutting liquid for recycling after further processing; then, grading the separated silicon carbide mixed with silicon powder, removing superfine silicon carbide with the mesh number larger than 1300 meshes, and preparing the residual silicon carbide with smaller mesh number into new cutting fluid for continuous use, wherein the residual silicon carbide and the separated superfine silicon carbide contain silicon powder because the densities of the silicon carbide and the silicon powder are not different; finally, the separated ultrafine silicon carbide mixed with silicon powder with larger number is discharged after chemical treatment. The existing cutting waste liquid treatment mode can only recycle polyethylene glycol and a part of silicon carbide, and the superfine silicon carbide and silicon powder in the cutting waste liquid cannot be effectively recycled.
At present, the classification treatment of the powdery materials mainly adopts a pneumatic classification mode, namely, the powdery materials with different meshes are flushed by high-pressure gas, and as the weights of the powdery material particles with different meshes are different, the powdery materials with different meshes can be piled up at different positions under the same wind power effect to realize the classification of the powdery materials, and the classification of the powdery materials can be realized by adopting the mode, but because the weights of the powdery material particles with different meshes are not different greatly, the powdery material particles with different meshes can be mixed together under the flushing of high-speed airflow, and the classification effect is poor.
