AI Technical Summary

⚠Technical Problem

Traditional wire cutting machines are not convenient for solid-liquid separation of mixed waste materials of silicon fragments and cutting fluid. Cutting fluid is difficult to purify and reuse, and the efficiency of extracting silicon fragments from mixed waste materials is low.

⚗Method used

An online silicon cutting waste collection device was designed, comprising a filtration component, a feeding component, and a circulation component. It utilizes activated carbon plates and microporous filters for solid-liquid separation, and uses cylinders and water pumps to circulate, purify, and reuse the cutting fluid.

🎯Benefits of technology

This technology enables efficient solid-liquid separation of silicon cutting waste and recycling of cutting fluid, reducing production costs and improving processing efficiency.
