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

Embodiment Construction

[0039] The technical solution of the present invention will be described in detail below in conjunction with specific embodiments. The following embodiments are only used to explain the technical solutions of the present invention more clearly, and therefore are only used as examples, and cannot be used to limit the protection scope of the present invention.

[0040] Such as Figure 1-4 As shown, the present invention provides a salt washing device for removing impurities of raw salt, including a feeding machine 1, a first inclined belt conveyor 2 and a salt washing mechanism 3;

[0041] In the prior art, under normal circumstances, the sulfate ion in the original salt is more than 1%; the calcium and magnesium ions are also more than 0.5%; this greatly increases the production cost of the two-alkali industry in the downstream industrial salt industry. The cost of processing calcium and magnesium ions is about 45 yuan / ton, and sulfate ions are difficult to deal with in actual prod...

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...
