Integrated coarse salt refining machine set

Abstract

The invention relates to a complete set, and especially relates to a complete set used for coarse salt refining. The complete set comprises a spiral salt washing machine, a first mixing agitator connected with the spiral salt washing machine, a second mixing agitator connected with the first mixing agitator, a tank body connected with the second mixing agitator, an evaporated device connected with the tank body and a pulverizer connected with the evaporated device. The box body of the spiral salt washing machine is an interlayer. Hot water other heat conduction fluid medium is arranged in the interlayer, and solid coarse salt can be dissolved rapidly. A NaOH solution and a BaCl solution are added in the first mixing agitator. A Na2CO3 solution is added in the second mixing agitator. the spiral material guiding wheel in the evaporated device comprises two sections: the section close to the tank body is a hollow section, and the section close to the pulverizer is a whole section. Compared with the prior art, the integrated coarse salt refining machine set is advantaged by simple structure, high efficiency, environmental protection and energy saving, and can achieve integrated production from coarse salt to fine salt.

Description

technical field [0001] The invention relates to a complete set of equipment, in particular to a complete set of equipment for refining coarse salt. Background technique [0002] Salt is a necessity for human life and a basic raw material for the chemical industry. It is also widely used in other industrial sectors and agriculture, animal husbandry and fishery. There are many salt-making processes today, but in the end only coarse salt can be obtained, which contains Ca 2+ , Mg 2+ , SO 4 2- soluble impurities such as silt and other insoluble matter, but the refinement of coarse salt often requires a variety of different devices to purify coarse salt multiple times through complex chemical reactions, which will encounter low purity, secondary pollution, and reaction Slow efficiency, unable to continuously produce and other issues. Contents of the invention [0003] The purpose of the present invention is to solve the aforementioned problems existing in the prior art, to ...
