An automatic powder scraping device for electrolytic copper powder

Abstract

The invention provides an automatic powder scraping device for electrolytic copper powder, and relates to the technical field of electrolytic copper powder. An automatic powder scraping device for electrolytic copper powder, used to scrape off the copper powder on the cathode plate, comprising: a lifting mechanism, the cathode plate is arranged on the lifting mechanism, and the lifting mechanism is used to drive the cathode The plate is raised from the electrolytic cell; the powder scraping mechanism, the powder scraping mechanism includes multiple groups of powder scraping assemblies, and each group of powder scraping assemblies includes two powder scraping parts arranged in parallel with each other; wherein, the powder scraping The mechanism also includes a moving assembly on which the powder scraping assembly is installed, and the moving assembly enables the powder scraping assembly to move horizontally to the lower side of the cathode plate, and the lifting mechanism drives the cathode plate Move down and pass through the gap between each set of said powder scraping parts. The automatic powder scraping device for electrolytic copper powder provided by the invention can realize simultaneous powder scraping of a plurality of cathode plates, improve production efficiency, and improve the quality of copper powder.

Description

technical field [0001] The invention relates to the technical field of electrolytic copper powder, in particular to an automatic powder scraping device for electrolytic copper powder. Background technique [0002] Because of its good electrical and thermal conductivity, corrosion resistance and non-magnetic properties, copper powder is widely used in industries such as electrical and thermal conductive materials, friction materials, electrical contact materials, diamond tool materials, oil-impregnated bearings, and electrical carbon products. There are many ways to prepare copper powder, mainly including reduction method, atomization method, electrolysis method, etc. Among them, electrolytic copper powder has the characteristics of high purity, good formability, and dendritic shape. , The main raw material of electric carbon products, and the quality of electrolytic copper powder has also become the decisive factor of the quality of finished products. [0003] During the el...

Problems solved by technology

[0005] However, the powder scraping device in the above-mentioned related art can only scrape powder on one cathode plate at a time. In the actual production process, multiple cathode plates work at the same time in the electrolytic cell, and the copper powder of the cathode plate in the same electrolytic cell is separated out. The speed is roughly the same, using the above-mentioned powder scraping device to scrape powder one by one on multiple cathode plates in the electrolytic cell takes a lot of time, the production efficiency is low, and there is a defect that the powder scraping is not synchronized, resulting in unstable quality of copper powder
