Iron filings magnetic separation device

Abstract

The invention relates to a magnetic separation device for scrap iron. The magnetic separation device for the scrap iron comprises a collecting tank, a magnetic roller and a scraper blade. The upper end of the collecting tank is provided with liquid drainage holes. The magnetic separation device further comprises a portal bracket crossing the collecting tank, and a driving device for driving the portal bracket to move back and forth in the length direction of the collecting tank. The magnetic roller comprises a roller shaft rotationally supported on the bracket, and a plurality of roller bodies arranged on the roller shaft in a sleeving mode at intervals. The roller shaft is driven by a first motor installed on the bracket. The roller bodies are located in the collecting tank, and each roller body is sleeved with a magnetic ring. The scraper blade is obliquely arranged on the bracket. The upper end of the scraper blade is provided with grooves corresponding to the multiple magnetic rings in a one-to-one mode. The grooves are used for scraping the scrap iron on the peripheral surface and the two side end surfaces of each magnetic ring. According to the magnetic separation device which is of the structure and used for the scrap iron, the scrap iron in emulsified liquid is separated through the magnetic roller, separating is thorough and good in effect, the content of the scrap iron in the emulsified liquid after separating is quite low.

Description

technical field [0001] The invention relates to a magnetic separation device for iron filings. Background technique [0002] At present, during the polishing and grinding of metal parts, emulsions are often used to wash iron filings and cool down metal parts. In this way, a large amount of iron filings will be mixed in the emulsion after use, which cannot be directly recycled and needs to be filtered before use. , but some very small iron filings will be produced during the metal processing process, which cannot be cleaned by ordinary filtration. The reuse of the emulsion containing such small iron filings will damage the circulating pump, affecting production and equipment use costs. [0003] The patent with application number 201520681586.2 discloses a magnetic iron filings separator, which uses a magnetic roller to absorb iron filings in the liquid, and then uses a scraper to scrape off the iron filings on the magnetic roller. However, the positions of the magnetic rolle...

AI Technical Summary

Problems solved by technology

However, the positions of the magnetic roller and the filter tank in this patent are relatively fixed, and the magnetic roller cannot collect the iron filings in the filter tank, so that the emulsion discharged through the filter holes on the filter tank carries a small amount of iron filings , will still cause damage to the circulation pump

In addition, this patent lacks a device for cleaning the iron filings accumulated on the scraper. When the iron filings accumulate too much, they can only be cleaned manually, which is inconvenient for production and use.
