Multi-stage screening and impurity removing device for high-purity industrial salt production

Abstract

The invention provides a multi-stage screening and impurity-removing device for high-purity industrial salt production, relates to the technical field of industrial salt processing equipment, and aims to solve the problem that industrial salt is easy to cake and inconvenient to discharge quickly when existing industrial salt is subjected to screening and impurity-removing. The multi-stage screening and impurity-removing device comprises a main body, a crushing mechanism, a material scattering mechanism and a screening mechanism, wherein supporting legs are mounted at the included angle positions of the bottom edge of the main body; the crushing mechanism is mounted in the main body; a transverse plate in the crushing mechanism is mounted at the top of the main body, and a circular convex block is arranged on the outer side of a vertical rod in the crushing mechanism; the material scattering mechanism is installed in the main body, the material scattering mechanism is located below the crushing mechanism, and a shifting plate in the material scattering mechanism is installed at the bottom of the vertical rod; and the screening mechanism is installed in the main body, and an inner groove in the screening mechanism is formed in the inner side of the main body. Supporting plates slide on the outer side of the vertical rod, so that pressing plates at multiple positions extrude the caked industrial salt, and the caked industrial salt is in a bulk state.

Description

technical field [0001] The invention belongs to the technical field of industrial salt processing equipment, and more specifically relates to a multi-stage screening impurity removal device for high-purity industrial salt production. Background technique [0002] Industrial salt is one of the most basic raw materials in the chemical industry. The main components are sodium chloride, sodium nitrite, etc. Compared with edible salt, industrial salt does not contain iodine, has a dark color, is mostly granular in shape, and has a large water content. When using industrial salt, it is necessary to screen the impurities in the industrial salt to improve the purity of the industrial salt. [0003] For example, the application number: CN201810519564.4 relates to a phosphate particle screening device, which includes a screening box and a feeding port connected to it, a sorting box is arranged in the screening box at the lower end of the feeding port, and a slide plate is arranged in ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a multi-stage screening and impurity removal device for the production of high-purity industrial salt to solve the problem that when the existing industrial salt is screened and removed, the industrial salt is easy to form agglomerates, which is not convenient for rapid screening and discharge. Manual crushing is time-consuming and labor-intensive, and in the process of industrial salt screening, the size of the sieve hole is single, and the screening compatibility for industrial salt with different particles is relatively poor. Replacement of sieve holes of different specifications increases the problem of production costs.
