Process and equipment for rapidly removing iron in slurry

Abstract

The invention provides a process and equipment for rapidly removing iron in slurry and belongs to a magnetic separation field of separating solid materials in fluid. The equipment comprises a slurry cylinder; a magnetic rod group is arranged in the slurry cylinder; a sealed air chamber is arranged at the upper end of the slurry cylinder; an elastic rubber casing pipe is arranged in the sealed air chamber; the magnetic rod group rises after a magnetic rod absorbs iron chips for certain time; when the magnetic rod passes through the elastic rubber casing pipe, the elastic rubber casing pipe and the magnetic rod are separated; the elastic rubber casing pipe protrudes towards the outer wall of the magnetic rod under an air pressure effect and is pressed on the outer wall of the magnetic rod; then the magnetic rod group falls down; the iron chips on the magnetic rod are adhered to the elastic rubber casing pipe after being removed; and the magnetic rod group continues to fall and reset, so that a primary iron removing process is completed. Compared with the prior art, motion states of the magnetic rod only have a rising process and a falling process. Furthermore, when the magnetic rod falls down, the iron chips not only can be removed but also can be absorbed in the slurry, so as to greatly reduce the time of removing the iron of each time and improve the production efficiency.

Description

technical field [0001] The invention belongs to the field of magnetic separation for separating solid materials from fluids, in particular to a process and equipment for removing iron filings from slurry by using permanent magnets. Background technique [0002] In the fields of chemical industry and ceramics, liquid slurry is often used as raw material to produce solid products. Because the minerals from the earth's crust itself contain a certain amount of iron. Because the prepared slurry contains a lot of iron filings, in the field of building ceramics for the manufacture of floor tiles or interior and exterior wall tiles, iron filings in the slurry will cause black spots in the produced floor tiles, which affects product quality. In view of this, slurry iron removal has become an important link in the production of ceramic enterprises. Due to the higher and higher requirements for the quality of ceramic products, the requirements for raw materials have also increased co...

AI Technical Summary

Problems solved by technology

During the time period when the magnetic bar group is lifted away from the slurry tank to remove iron filings, the equipment cannot carry out the iron removal operation of absorbing iron filings from the slurry, resulting in a decrease in production efficiency and unable to meet the production needs of modern construction ceramics factories
