Device and method for cyclone separation and reduction of single crystal grains of waste salt

Abstract

The invention relates to a device and a method for cyclone separation and reduction of single crystal grains of waste salt. The device comprises a crusher and a cyclone separation assembly, a heating layer is arranged on the outer wall of the crusher, waste salt blocks and saturated salt water are mixed in the crusher and are heated and decomposed through the heating layer, then the waste salt blocks and the saturated salt water are crushed through the crusher to obtain a mixed material of coarse salt, single-grain salt and the saturated salt water, the mixed material is extracted and separated through a cyclone separation assembly, and the coarse salt, the single-grain salt and the saturated salt water are obtained respectively. Wherein the crude salt and the saturated salt water flow back into the crusher to be continuously decomposed and reduced. Through cooperation of the saturated salt water, the heating layer, the crusher and the cyclone separation assembly, waste salt blocks are decomposed into coarse salt, single-grain salt and the saturated salt water, then the coarse salt, the single-grain salt and the saturated salt water are separated, the single-grain salt is obtained, and the whole device can work continuously and is high in processing efficiency, simple in structure and long in service life.

Description

technical field [0001] The invention belongs to the technical field of waste salt treatment, and in particular relates to a device and method for cyclone separation and reduction of single grains of waste salt. Background technique [0002] Generally, industrial waste salt needs to be stored for one month after treatment. As the water gradually evaporates, the organic matter contained in it will gradually oxidize and will act as a binder to bond the salt grains together to form a very hard salt block. It needs to be crushed first, and then screened through a filter screen. In order to save equipment costs and reduce floor space in the prior art, crushing and screening are generally set up as an integrated machine structure, which can crush and screen salt blocks at one time. However, due to the low support strength of the filter screen, this kind of integrated equipment may easily damage the internal filter screen of the crusher due to the high hardness of the salt block, wh...

[0002] Generally, industrial waste salt needs to be stored for one month after treatment. As the water gradually evaporates, the organic matter contained in it will gradually oxidize and will act as a binder to bond the salt grains together to form a very hard salt block. It needs to be crushed first, and then screened through a filter screen. In order to save equipment costs and reduce floor space in the prior art, crushing and screening are generally set up as an integrated machine structure, which can crush and screen salt blocks at one time. However, due to the low support strength of the filter screen, this kind of integrated equipment may easily damage the internal filter screen of the crusher due to the high hardness of the salt block, which in turn will easily affect the quality and efficiency of crystal salt discharge.
