Description

A pickling system for powder materials

technical field

The utility model relates to the field of powder material production equipment, in particular to a powder material pickling system.

Background technique

With the continuous development of material technology, the application of submicron or nanometer powder is more and more extensive. Due to the huge specific surface area of submicron or nanometer powder, the surface effect and interface effect show many unique physical and chemical properties. It can be made into various shapes such as spherical, polygonal, and flake according to the application. Such powder materials have been widely used in chemical catalysis, electromagnetics, optics, electricity, electronic information, fuel cells, and biomedicine. . People have used different methods to prepare various nanopowders, but after the powder synthesis reaction is completed, a variety of anions and cations remain in the solution. If they are not cleaned, the performance of the nanopowders will be affected. For the powder pickling process, in the prior art, there is no high-efficiency and automatic equipment to complete it. The steps in the pickling process of powder materials include: acid soaking, acid discharge, water washing, and drainage. If they are all completed manually, the process is cumbersome, time-consuming and labor-intensive, and the work efficiency is very low.
