Description

Technical Field

[0001] The utility model relates to the technical field of crystallization devices, in particular to a continuous crystallization device. Background Art

[0002] Potassium dihydrogen phosphate is a chemical with deliquescent properties. When heated to 400°C, it melts into a transparent liquid and solidifies into an opaque glassy potassium metaphosphate after cooling. It is stable in the air, soluble in water, and insoluble in ethanol. It is used as a buffer and culture agent in industry; it is also used as a bacterial culture agent, a flavoring agent for synthesizing sake, a raw material for making potassium metaphosphate, a culture agent, a fortifier, a bulking agent, and a fermentation aid for brewing yeast, and is used as a high-efficiency phosphorus-potassium compound fertilizer in agriculture. At present, the main process methods for producing potassium dihydrogen phosphate in my country include neutralization, extraction, double decomposition, and ion exchange. The common point of the above preparation methods is that first, a potassium dihydrogen phosphate solution is obtained by reaction, and then the obtained solution is concentrated, crystallized, centrifuged, dried, and other steps to obtain the final product. Among them, the steps of concentration, crystallization, centrifugation, drying, etc. are all part of the process of separating and purifying potassium dihydrogen phosphate. In this process, the uneven crystal particles will affect the effect of centrifugation, so it is necessary to crush the crystallized potassium dihydrogen phosphate and then collect it.

[0003] The existing technology has the following problems:

The patent uses a crushing barrel to crush the raw materials, and then filters the crushed raw materials through the connecting plate to obtain particles of uniform size.

[0005] However, there are still some problems that need to be improved in the actual use of the above patent. The most obvious one is that the crushing effect of the raw materials is not ideal, resulting in a long time required for uniform crushing, which affects the crushing efficiency.

[0006] To this end, we proposed a continuous crystallization device to solve the above-mentioned drawbacks. Utility Model Content
