Salt leaching device and salt leaching method for removing impurities in crude salt

Abstract

The invention belongs to the technical field of salt production equipment, and provides a salt leaching device and a salt leaching method for removing crude salt impurities. The salt leaching device comprises a feeding machine, a first inclined belt conveyor and a salt leaching mechanism, wherein the salt leaching mechanism comprises a salt leaching tank, a clear water tank, a brine injection cylinder and a separation tank; the first inclined belt conveyor is correspondingly arranged at the upper part of one end of the salt leaching tank, and the other end of the salt leaching tank communicates with the separation tank; a clear water inlet pipe is arranged on the outer wall of the salt leaching tank, and one end of the clear water inlet pipe is connected with the clear water tank; a motoris arranged on the outer wall of the separation tank; a spiral separation shaft is arranged in the separation tank, and the motor is connected with the spiral separation shaft; a crude salt outlet isformed in the end of the separation tank; a wastewater outlet pipe is arranged at the tail end of the separation tank. According to the salt leaching device and the salt leaching method for removing the impurities in the crude salt, the crude salt can be cleaned, the impurities in the crude salt are removed, and the quality of the crude salt is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of salt production equipment, in particular to a salt washing device and a salt washing method for removing impurities of raw salt. Background technique [0002] Raw salt refers to salt that has only been preliminarily sun-dried or boiled; that is, the salt produced by the salt farm (factory) has not been purchased and distributed by the salt transport and sales unit or the state-designated purchase unit, or the salt production unit has not been supplied by the salt industry (factory) The salt sold; generally contains more impurities and is mostly used as industrial raw materials; [0003] Salt resources in our country are extremely rich and have a wide range of uses. According to the source of salt production, there are sea salt, pool salt, mineral salt, well salt, and soil salt; according to use, there are edible salt (including iodized salt), fishery salt, Salt for agriculture and animal husbandry, salt for ind...

AI Technical Summary

Problems solved by technology

[0003] my country's salt resources are extremely rich and have a wide range of uses. According to the source of salt production, there are sea salt, pond salt, mine salt, well salt, and soil salt; according to the use, there are table salt (including iodized salt), fishery salt, Agricultural and animal husbandry salt, industrial salt, export salt, etc.; in the prior art, the quality of domestically produced sea and lake salt is poor, and the impurity ions are high, which greatly reduces the quality of raw salt
