Problems solved by technology

[0002] At present, the purity of calcium hydroxide on the market is low. The reason is that there is a lack of refined treatment methods for calcium hydroxide in the preparation process, and high-purity calcium hydroxide needs to be air-selected during the preparation process to screen out impurities. , to ensure the purity, but the processing efficiency of some air separation equipment is low at present, and it will contain agglomerated calcium hydroxide, which will be treated as impurities during the air selection process, causing unnecessary economic losses, and most of the equipment is inconvenient Importing and discharging calcium hydroxide after winnowing, such as the patent with publication number CN212550507U, the actual use effect is poor, and a large amount of calcium hydroxide powder remains in the equipment after processing, which affects the shipment volume and the quality of subsequent processing operations, and it is also inconvenient to clean up , poor practicability, not conducive to promotion and use

Abstract

The invention discloses a high-purity calcium hydroxide preparation process and equipment, and relates to the technical field of high-purity calcium hydroxide processing. The high-purity calcium hydroxide preparation process comprises the four steps of crushing, digesting, water distribution and winnowing. The high-purity calcium hydroxide preparation equipment comprises a base; a winnowing mechanism and an output mechanism are arranged at the top of the base; a processing mechanism is arranged at the top of the winnowing mechanism; a feeding mechanism is arranged at the top of the output mechanism; and a discharging mechanism is arranged between the processing mechanism and the feeding mechanism. According to the high-purity calcium hydroxide preparation equipment, calcium hydroxide can be crushed and screened before winnowing, so that blocky calcium hydroxide is pulverized, the blocky calcium hydroxide is prevented from being cleaned as impurities due to the gravity effect in the winnowing process, and unnecessary economic losses are reduced; and calcium hydroxide to be winnowed is fed in a negative pressure mode, and compared with a manual feeding mode, the operation is easy, high efficiency and practicability are achieved, and the production and processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of high-purity calcium hydroxide processing, in particular to a high-purity calcium hydroxide preparation process and equipment. Background technique [0002] At present, the purity of calcium hydroxide on the market is low. The reason is that there is a lack of refined treatment methods for calcium hydroxide in the preparation process, and high-purity calcium hydroxide needs to be air-selected during the preparation process to screen out impurities. , to ensure the purity, but the processing efficiency of some air separation equipment is low at present, and it will contain agglomerated calcium hydroxide, which will be treated as impurities during the air selection process, causing unnecessary economic losses, and most of the equipment is inconvenient Importing and discharging calcium hydroxide after winnowing, such as the patent with publication number CN212550507U, the actual use effect is poor, and a larg...
