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. The automatic powder scraping device for the electrolytic copper powder is used for scraping off the copper powder on a negative plate, and comprises a lifting mechanism and a powder scraping mechanism, wherein the negative plate is arranged on the lifting mechanism, and the lifting mechanism is used for driving the negative plate to rise from an electrolytic cell; the powder scraping mechanism comprises a plurality of groups of powder scraping assemblies, and each group of powder scraping assemblies comprises two powder scraping parts which are parallel to each other and are arranged at intervals; and the powder scraping mechanism further comprises a moving assembly, the powder scraping assemblies are installed on the moving assembly, the moving assembly enables the powder scraping assemblies to horizontally move to the lower side of the negative plate, and the lifting mechanism drives the negative plate to move downwards and penetrate through a gap between each group of powder scraping parts. According to the automatic powder scraping device for the electrolytic copper powder, the multiple negative plates can be scraped off at the same time, the production efficiency is improved, and the quality of the copper powder is improved.

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
