Water washing and separation method of copper powder and shaker with controllable water flow

Abstract

The invention relates to a method for washing and separating copper powder and a shaker with controllable water flow. The main process steps of the present invention are: first screen the mixture of non-metallic powder and copper powder obtained after crushing, and then pump the obtained qualified mixture particles to the shaker distribution device for distribution by electric pump, and evenly distribute them to Each shaker with controllable water flow is washing and sorting; this method is equipped with screening and material separation operations, combined with the improved washing shaker, to achieve uniform distribution of materials and improve production efficiency and separation effect and the method Simple and easy to implement; the shaker with controllable water flow of the present invention is mainly composed of a shaker body, a feed tank, a water adding tank and a water flow adjustment device, which improves the existing washing shaker technology, and is easy to add water in the production process, and It can realize the control of the flow of adding water, and can improve the efficiency of sorting operation. It has strong practicability, simple structure, and strong practicability and popularization value.

Description

technical field [0001] The invention relates to a water washing and separation method for materials and equipment thereof, in particular to a water washing and separation method for copper powder and a water washing shaker with controllable water flow when recycling copper metal from waste metal circuit boards and printed circuit boards. Background technique [0002] With the rapid development of science and technology, information, and electronics industries, the upgrading of various electronic products has accelerated, and a large amount of electronic waste has also been generated, and the number of discarded metal circuit boards and printed circuit boards has also increased. The main components of such metal circuit boards and printed circuit boards are metal materials such as copper and silver, and non-metallic materials mainly composed of thermosetting plastics containing special additives. Therefore, such electronic waste is usually recycled and reprocessed , Separatin...

AI Technical Summary

Problems solved by technology

However, in the existing washing shaker technology, there is no corresponding device for conveniently adding water in the shaker, and there is no device that can control and adjust the supplementary water flow, so the sorting operation efficiency of the wash shaker is low. It also affects the overall production efficiency, and the deficiencies of existing technologies limit the development of copper metal recovery technology to a certain extent
