Novel stock fluid deironing method and device

Abstract

The invention relates to a novel stock fluid deironing method and a device, which is characterized by comprising a stock fluid deironing process and a magnetic rod washing process, wherein the tock fluid deironing process is that: the stock fluid flows upwards from the bottom part of a vertical cavity, and the stock fluid flows out to a stock groove from an outlet on the side surface of the upperpart of the cavity after being deironized by a permanent-magnetic body rod which is vertically arranged inside the cavity; and the magnetic rod washing process is that: the stock fluid deironing process is firstly stopped, then a scraping sleeve which is previously arranged on the top part of the permanent-magnetic rod is moved downwards along the permanent-magnetic body rod through a power mechanism, so the ferromagnetic substance which is attached onto the permanent-magnetic body rod is scraped onto a non-magnetic conductive material rod on the lower end of the permanent-magnetic body rod, the ferromagnetic substance is washed away from the non-magnetic conductive material rod on the lower end of the permanent-magnetic body rod through a washing device, the washed-away ferromagnetic substance is discharged through a drain valve which is arranged below the cavity, and the scraping sleeve is pulled back to the top part of the permanent-magnetic rod through the power mechanism so as toreprocess the stock fluid deironing process. Compared with the prior art, the novel stock fluid deironing method has the advantages that the cleaning steps are fewer, the actuating mechanisms are fewer and the actuating mechanism is free from being influenced by the penetration of the stock.

Description

Technical field: [0001] The invention relates to a mineral separation method and device. Background technique: [0002] The magnetic rod cleaning in the existing magnetic rod type slurry fluid iron removal technology generally includes sending the magnetic rod forward to the cleaning room, putting a scraper on the magnetic rod, and moving the magnetic rod backward to make the scraper remove the iron on the magnetic rod. The magnetic material is scraped off and the magnetic rod is rinsed with a flushing device at the same time. The whole process requires three steps and two action mechanisms. The two action mechanisms are the movement of the magnetic rod and the opening and closing of the scraper sleeve. Parts are in contact with the slurry, and the slurry is easy to penetrate into the transmission part. Once the slurry penetrates into the transmission part, it will seriously affect the normal operation of the transmission part. In addition, there are many action steps, which...
