A magnetic roller filter

Abstract

The invention relates to treatment equipment for a nonmetal liquid, in particular to a magnetic roller type filter for removing ferreous substances, surface oil dirt and the like of a nonmetal mixed liquid. The magnetic roller type filter comprises an accommodating cavity with a liquid inlet and a liquid outlet; a dustproof cover is arranged on the accommodating cavity; a magnetic roller and an oil removal roller are arranged in the accommodating cavity and both driven by a speed reducer motor to rotate; a slag scrapping device basically clung to the surface of the magnetic roller is arranged at the part, above a liquid level, of the magnetic roller; an oil scrapping device closely lung to the surface of the oil removal roller is arranged at the part, above the liquid level, of the oil removal roller; a flow guide plate for dividing the accommodating cavity into a slag removing cavity and a purification cavity is arranged below the magnetic roller and the oil removal roller. The magnetic roller type filter not only can remove the ferrous substances and the oil dirt, but also has a high filtration effect and a stable structure.

Description

technical field [0001] The invention relates to non-metallic liquid treatment equipment, in particular to a magnetic roller filter for removing ferrous substances and surface oil stains in non-metallic mixed liquid. Background technique [0002] Water is an essential condition for human survival. The amount of industrial water is large, and recycling is a good way to save water resources; however, industrial circulating water is mixed with a large amount of iron impurities and oil in the application. [0003] At present, most of the magnetic filters for removing ferrous impurities in non-metallic liquids adopt the pin connection and chain transmission of several magnetic rods. However, the existing structure and type have obvious deficiencies in the practical application level in terms of effectively and reliably removing impurities on the magnetic bar. The following points: [0004] 1. In practical application, the circulating water not only contains a large amount of ir...

AI Technical Summary

Problems solved by technology

[0004] 1. In practical application, the circulating water not only contains a large amount of iron substances, but also contains a large amount of oil pollution. The existing filter is effective in absorbing iron substances, but it does not have the function of removing oil pollution at the same time;

[0005] 2. There are obvious dead angles in the scraping slag of the existing filter, the scraping slag is not thorough, and the actual filtering effect is not ideal;

[0006] 3. The existing filter slag scraping mechanism and conveying mechanism are obviously vulnerable, and the structure is intertwined and complicated, so it is extremely troublesome to replace the vulnerable parts;

[0007] 4. The magnetic bar of the existing filter adopts the pin-connected chain transmission type, and the chain is often broken when cooperating with each other, which leads to interruption of equipment operation or even damage
