Chain bar type permanent magnet filter

Abstract

The invention relates to a chain bar type permanent magnet filter. The chain bar type permanent magnet filter comprises a box, magnetic bar chains which are arranged in the box and can rotate around themselves, sludge scraping mechanisms arranged on the magnetic bar chains and sludge tanks which are arranged under the sludge scraping mechanisms and located in the magnetic bar chains; sludge conveying mechanisms are arranged in the sludge tanks, and each magnetic bar of the magnetic bar chains is sleeved with a scraping sleeve in a matched mode; each sludge scraping mechanism comprises a moving block capable of moving in the axial direction of the corresponding magnet bars in a reciprocating mode, two scrapers capable of only swinging in the axial direction of the corresponding magnetic bars are hinged to the lower portion of each moving block, can swing towards the side close to each other and reset and cannot swing to the side far away from each other, and the bottoms of the scrapers are lower than the tops of the scraping sleeves when the scrapers do not swing. The filter is simple in structure, low in cost, capable of ensuring continuous operation, good in scraping effect and convenient to maintain.

Description

technical field [0001] The invention belongs to the field of magnetic filtering equipment, and in particular relates to a chain rod type permanent magnetic filter. Background technique [0002] In recent years, most domestic automobile and home appliance manufacturers have paid more and more attention to the surface cleanliness of steel plates. The two main production processes that affect strip surface cleanliness are cold rolling of strip and alkaline degreasing. When the strip is cold-rolled, in order to lubricate and cool the roll, an emulsion (mainly composed of rolling oil) is sprayed on the surface of the strip and the roll; on the other hand, due to the grinding of the roll on the surface of the strip, a large amount of iron will be produced Powder, and adhere to the strip. In the degreasing and cleaning section, the residual rolling oil can be easily removed by using a sodium hydroxide type cleaning agent, but iron powder is difficult to remove due to its inherent...

Problems solved by technology

However, this rail-type magnetic filter requires a set of special-shaped rails, and the installation and adjustment of the rails are difficult to implement, and the bearing rollers on the sleeve-type slag scraper will run in the rails due to the dirt on the magnetic rods (working The environment is poor) and it is difficult to operate when it enters the track. The scraping device with this structure has a large operating resistance and a relatively high failure rate. Once a failure occurs, it is very difficult to deal with

Therefore, it is necessary to find a more complete solution to overcome the defects of the existing technology such as high failure rate and poor scraping effect, so as to improve the performance of magnetic filtration
