Description

Technical Field

[0001] The present invention relates to the technical field of chemical raw material processing, in particular to a chemical multi-stage pretreatment device and a processing method thereof. Background Art

[0002] Before raw materials enter the production process, they must be pre-processed to ensure normal production and improve production efficiency. Chemical raw material pretreatment mainly includes two processes: impurity removal and crushing, depending on the raw material.

[0003] However, while existing production methods can pre-treat chemical raw materials, they still have many drawbacks: 1. During the pre-treatment process, all chemical raw materials are primarily thrown together, stirred, and crushed, resulting in local solubility differences when the chemical raw materials are mixed, which results in poor processing of the chemical raw materials. 2. Existing chemical raw materials have different pre-treatment methods based on their different physical and chemical properties, resulting in different chemical raw materials and different internal components. Traditional chemical raw materials are directly placed in the crushing chamber, but the pre-treatment effect is poor due to the cohesiveness of the side walls and the internal mixture.

[0043] A treatment method for a chemical multi-stage pretreatment device comprises the following steps:

[0044] S11.

[0046] S13. When the diameter of the chemical raw materials input is large, there are impurities adhering to the raw materials, and the requirements for the crushed chemical raw materials are high, the raw materials are input from the feed hopper 1 6 and the feed hopper 2 7. At the same time, the chemical raw materials are quickly crushed under the action of the conical section 1 9 and the conical section 2 10. At the same time, when at least three or more raw materials are mixed, rapid mixing is achieved under the action of the fine mixing chamber. The effect after mixing is better than that of the existing pretreatment device.

[0047] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
