Monocrystalline silicon rod multi-stage pickling equipment for battery production

Abstract

The invention discloses monocrystalline silicon rod multistage pickling equipment for battery production and belongs to the technical field of monocrystalline silicon rod multistage pickling equipment. The equipment comprises a liquid supply tank and a stainless steel cross frame; one side of the liquid supply tank is connected with a connecting pipe; one side of the connecting pipe is connected with a water pump; one side of the water pump is connected with a first water pump; a box body is mounted on one side of the first water pump; a turnover mechanism is mounted above the stainless steelcross frame; the stainless steel cross frame is positioned in the box body; the turnover mechanism is provided with a nozzle; and a liquid supply pipe is mounted above the nozzle. The monocrystallinesilicon rod multistage pickling equipment for battery production is provided with a second water pump, a return pipe and a liquid guide pipe; waste liquid can flow back into a storage tank along the interiors of the return pipe and the liquid guide pipe, so that the used waste liquid is recycled; and since a user can conveniently recycle the waste liquid, the utilization efficiency of acid liquidis improved, and water source pollution caused by random discharge of the waste liquid is avoided.

Description

technical field [0001] The invention relates to the technical field of multi-stage pickling equipment for single crystal silicon rods, in particular to a multi-stage pickling equipment for single crystal silicon rods for battery production. Background technique [0002] A battery refers to a cup, tank, or other container or a part of a composite container that contains an electrolyte solution and a metal electrode to generate current, and is a device that converts chemical energy into electrical energy; single crystal silicon is a crystal with a substantially complete lattice structure. Different directions have different properties, and it is a good semiconducting material for the manufacture of semiconductor devices, solar cells, etc. [0003] During the use of the existing multi-stage pickling equipment for single crystal silicon rods, the cleaning area of ​​single crystal silicon rods is small, so that part of the single crystal silicon rods cannot be cleaned, and stains...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a multi-stage pickling equipment for monocrystalline silicon rods for battery production, which solves the problems in the use process of the existing multi-stage pickling equipment for single crystal silicon rods proposed in the above-mentioned background technology. , the cleaning area of ​​the single crystal silicon rod is small, so that part of the single crystal silicon rod cannot be cleaned, and stains are easy to remain, and the waste liquid generated by equipment cleaning is likely to cause environmental pollution, so that the waste liquid cannot be reused. It is easy to cause the problem of waste of liquid
