Description

TECHNICAL FIELD

[0001] The application relates to the field of chemical production equipment, in particular to a mixed reactor for preparing potassium perchlorate. BACKGROUND

[0002] Potassium perchlorate is an inorganic compound with the chemical formula KClO4, which is a colorless or white crystalline powder, can be dissolved in water, is insoluble in diethyl ether and ethanol, and is more stable than potassium chlorate. At the melting point, it will decompose into potassium chloride and oxygen. It can be used as a smoke agent, an igniter, an oxidizing agent and a chemical analysis reagent.

[0003] The traditional production process of preparing potassium perchlorate is the double decomposition method, which has the advantages of being more environmentally friendly, low in cost, high in product quality and the like because the generated sodium chlorate in the process of producing potassium perchlorate can be recycled and no waste is discharged. However, the following problems exist.

[0004] In the process of preparing potassium perchlorate, the material is usually a high-viscosity, multi-phase (solid-liquid) mixed system, and may be accompanied by crystallization. The existing stirring device generally adopts a blade type stirring, but there are problems of uneven mixing and regular movement of the material affecting the efficiency. Although multiple blades are used, it is unreasonable in a large tank. Although variable speed stirring can partially solve the problem, the cost of variable frequency equipment is high, which increases the burden of enterprises. Therefore, how to efficiently and uniformly mix such complex materials, reduce equipment cost and improve maintenance convenience is a problem to be solved in the field. SUMMARY

[0005] Technical problems solved

[0006] In view of the deficiencies of the prior art, the application provides a mixed reactor for preparing potassium perchlorate, which solves the problems of

[0007] 1. The existing potassium perchlorate production mixing tank still needs personnel to be on site for supervision. Since the production of potassium perchlorate is a relatively dangerous process, the presence of personnel cannot protect the safety of life in the event of a safety accident, and the life of personnel cannot be guaranteed.

[0008] 2. The raw material mixing of the existing potassium perchlorate production still adopts blade type stirring and mixing. Due to the fluid characteristics of the blade itself, regular movement of the mixture will be caused in the stirring process, affecting the mixing efficiency. Although multiple blades are used to improve the situation, it is unreasonable to arrange a large number of blades in a large tank. The use of variable speed can partially solve the problem, but the construction cost of the variable frequency equipment is high, which is a heavy burden on enterprises.

In addition, an impact groove is opened on the surface of the stirring blade. During the stirring process, the mixture can be impacted by the impact force of the rotating blade and then impact the objects in the groove area to form a flow channel along both sides of the impact groove, thereby further impacting the regular movement of the objects, improving the mixing efficiency, and further reducing the mixing time. At the same time, the use of blades with a mechanized fluid structure can avoid the high cost of using frequency conversion equipment and reduce the burden on enterprises.
