Scraper plate assembly for electrolysis, scraper plate mechanism and electrolytic tank powder scraping device

Abstract

The invention belongs to the technical field of electrolytic cell powder scraping, and particularly relates to a scraper assembly for electrolysis, a scraper mechanism and an electrolytic cell powder scraping device.The scraper assembly for electrolysis comprises a connecting arm and two moving plates arranged in parallel, the two ends of the connecting arm are hinged to the two moving plates correspondingly, the two moving plates are each provided with a scraper, and the scrapers are located between the two moving plates; the connecting arm can rotate around the middle of the connecting arm, and when the connecting arm rotates, the two moving plates move in opposite directions, so that the scraping plates on the two moving plates are close to or far away from each other; the two scraping plates can clamp a cathode plate for powder scraping operation, and when the two scraping plates are opened, the scraping plates moving in a reciprocating mode can play a role in stirring electrolyte. The scraping plate assembly is low in machining and mounting difficulty, the manufacturing cost can be controlled easily, the problem that the distance cannot be adjusted or errors exist in distance adjustment due to the fact that the bolts are corroded by volatilization of electrolyte is solved, and the scraping plate assembly is higher in use reliability, simpler and more effective in structure and convenient to maintain.

Description

technical field [0001] The invention belongs to the technical field of scraping powder in an electrolytic cell, and in particular relates to a scraper assembly for electrolysis, a scraper mechanism and a powder scraping device in an electrolytic cell. Background technique [0002] During the electrolysis process, the target metal ions in the electrolyte get electrons on the cathode plate, reduce to target metal powder, and precipitate on the cathode plate. In order to prevent the precipitated metal powder from affecting the subsequent electrolysis process, a scraper structure is usually used to reciprocate along the surface of the cathode plate to scrape off the metal powder. However, in the scraper mechanism in the prior art, the distance between the two scrapers is difficult to adjust. It can only be applied to a single size cathode plate and has a single function. The Chinese patent of CN202110898981.6 provides an automatic powder scraping device for electrolytic copper ...

Problems solved by technology

However, in this solution, the processing of the screw and the scraper and the screw structure is difficult, the manufacturing cost is high, and the electrolyte is corrosive, and there is acid mist volatilization during use, which is easy to corrode the thread, and it is easy to get stuck or thread after a period of use. In the case of failure, the service life is short and maintenance is troublesome
