Magnetic separation equipment and magnetic separation method for quartz sand

Abstract

The invention discloses magnetic separation equipment and a magnetic separation method for quartz sand. The equipment comprises a magnetic separation bin and a feeding hopper fixedly connected to thetop of the magnetic separation bin; a crushing device is arranged in the feeding hopper, and comprises a crushing motor and a crushing roller; a magnetic separation device is arranged in the magneticseparation bin; the magnetic separation device comprises a driving wheel, a driven wheel and a conveying belt connected to the driving wheel and the driven wheel; electromagnets are arranged on the upper side and the lower side in the conveying belt; the left side of the magnetic separation bin is provided with a magnetic scraping device; the magnetic scraping device comprises a magnetic scrapingplate and a base connected with the magnetic scraping plate in a sliding mode; the base is fixed on the inner side wall of the magnetic separation bin; a sliding groove is formed in the top of the base; and one end of the magnetic scraping plate is connected in the sliding groove in a sliding mode through a spring, and the other end of the magnetic scraping plate abuts against the conveying belt.The magnetic separation equipment has the advantages that the magnetic separation effect is good, magnetic substances in the quartz sand can be effectively removed, and the purity of the quartz sand is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic separation equipment, in particular to a magnetic separation equipment for quartz sand and a magnetic separation method thereof. Background technique [0002] Quartz sand is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral, and its main mineral component is SiO 2 , the color of quartz sand is milky white, or colorless and translucent, with a hardness of 7. Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical solvents , metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. [0003] The purification of quartz sand is one of the more critical processes. At present, magnetic separation is mostly used for purification of quartz sand to remove magnetic ore in quartz sand and increase the c...

AI Technical Summary

Problems solved by technology

However, the traditional magnetic separation equipment has poor magnetic separation and separation effect, and it is difficult to achieve the purpose of purifying quartz sand.

[0004] The prior art CN207839187U protects a quartz sand dry-type magnetic separator. This technical solution realizes the magnetic separation of the quartz sand, but the magnetic separation is based on a semi-circular permanent magnet to separate the magnetic substance from the quartz sand. The disadvantage is that the magnetic substance When transported to the right end of the magnetic separation layer by the conveyor belt, some magnetic substances will be transported to the upper part of the magnetic separation device again, and cannot completely fall to the waste sand discharge port below, and the purification effect is not good.

In addition, the uniform dispersion of quartz sand in the prior art is realized through the stirring layer. By setting the stirring layer, the volume of the magnetic separation device is increased, and the dispersion cannot be completely uniform.
