A new energy battery monocrystalline silicon rod multi-stage pickling equipment

Abstract

The invention discloses a new energy battery monocrystalline silicon rod multi-stage pickling equipment. The invention is an assembly line type, and the pickling is carried out uniformly and step by step through the assembly line, which greatly improves the pickling efficiency. At the same time, there is a pickling Pool, clean water pool and drying pool, can carry out pickling, cleaning and drying operations on the monocrystalline silicon rods to ensure that the processed monocrystalline silicon rods are dry and clean. The invention enables the pickling solution to be circulated, saving resources, on the other hand, to avoid environmental pollution caused by acid leakage, the silicon rod transmission frame is used in conjunction with the silicon rod clamping frame, so that the present invention rotates the single crystal silicon rod during the moving process, so that the single crystal silicon rod is During pickling, cleaning and drying, it can contact the working parts in all directions, greatly improving the degree and efficiency of pickling, cleaning and drying. Compared with similar products on the market, the present invention has the advantages of clean cleaning, high processing efficiency, high pickling Good efficiency and other beneficial effects.

Description

AI Technical Summary

Problems solved by technology

[0003] Most of the existing multi-stage pickling equipment for monocrystalline silicon rods adopts the single-batch immersion cleaning method. The cleaning quantity of this method is small and cannot be cleaned in an assembly line. When the number of single crystal silicon rods is large, it needs to be processed and cleaned in batches. , the cleaning efficiency is low, and the immersion cleaning method is adopted at the same time. Since the acid solution in the cleaning pool cannot be flown and replaced, after multiple cleanings, the acid solution in the acid solution pool is neutralized, resulting in a significant drop in pickling efficiency, resulting in Therefore, it is imminent to develop a multi-stage pickling equipment for monocrystalline silicon rods of new energy batteries that is efficient, pipeline-type, high in pickling efficiency, and convenient in the pickling process.
