Multifunctional magnetic separator for polyamide production

Abstract

A multifunctional magnetic separator for polyamide production belongs to the field of polyamide production and comprises a box with an opening at the top, a fixing shaft is longitudinally arranged inthe box, the front end and the rear end of the fixing shaft are fixedly connected with corresponding side walls of the box respectively, an arc magnet is fixedly arranged below the fixing shaft, and acoaxial roller sleeves outside the fixing shaft. A through groove is formed in the side, away from the magnet block, of the arc-shaped plate, an opening in the lower end of the through groove is fixedly connected with the upper end of a drainage pipe, and the drainage pipe goes down through the bottom plate of the box body. The magnetic separator realizes simultaneous separation of scrap iron andnon-magnetic solid particles in liquid, is richer and more practical in function compared with an existing magnetic separator, only needs to be driven by a motor, simplifies a complex structure thatan existing wet magnetic separator needs to be provided with a high-pressure water gun, has reduced manufacturing cost, utilizes the magnetic force of the magnet separator to realize themultiple functionsthat a scraper blade can scrape iron fillings on a roller, and can clear up sedimentary solid particles of the top surface of the arcplate. The magnetic separator is suitable for popularization inthe field of polyamide production.

Description

technical field [0001] The invention belongs to the field of polyamide production, in particular to a multifunctional magnetic separator for polyamide production. Background technique [0002] During the production of polyamide, it is necessary to separate and remove the iron filings generated by the reaction in the raw material mixture. At present, wet magnetic separators are mostly used for iron filing separation. The existing wet magnetic separator absorbs iron filings on the rotating drum, and then passes through The high-pressure water gun falls down into the chip flute to complete the separation, and the solution without iron filings flows from the other side to the drain port to the next sequence. The existing wet magnetic separator uses a high-pressure water gun to consume a lot of water and electricity. It can separate iron filings in the solution, but cannot separate non-metallic particles from water. In addition, many non-metallic particles will not flow to the dr...

[0002] During the production of polyamide, it is necessary to separate and remove the iron filings generated by the reaction in the raw material mixture. At present, wet magnetic separators are mostly used for iron filing separation. The existing wet magnetic separator absorbs iron filings on the rotating drum, and then passes through The high-pressure water gun falls down into the chip flute to complete the separation, and the solution without iron filings flows from the other side to the drain port to the next sequence. The existing wet magnetic separator uses a high-pressure water gun to consume a lot of water and electricity. It can separate iron filings in the solution, but cannot separate non-metallic particles from water. In addition, many non-metallic particles will not flow to the drain with the solution. Users need to clean the inside of the magnetic separator regularly, which restricts production efficiency.
