After industrial wastewater evaporation and crystallization, centrifugal dehydration equipment is used to further remove water from the evaporated and crystallized material to achieve a higher solid content or meet specific treatment requirements. However, there are the following shortcomings in its use:

[0003] 1. Some existing centrifugal dehydration equipment needs to be cleaned internally after use, which often requires the equipment to be disassembled for cleaning. The equipment is not easy to self-clean, and its disassembly and cleaning process is often tedious and complicated. It not only requires professional operators and tools, but also takes a lot of time and energy, thereby increasing the cost of maintenance and replacement.

[0004] To this end, we proposed a centrifugal dehydration equipment for industrial wastewater after evaporation and crystallization. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that some centrifugal dehydration equipment needs to be cleaned internally after use, which often requires the equipment to be disassembled for cleaning. The equipment is not convenient for self-cleaning, and its disassembly and cleaning process is often tedious and complicated, which not only requires professional operators and tools, but also takes a lot of time and energy, thereby increasing maintenance and replacement costs. A centrifugal dehydration equipment for industrial wastewater after evaporation and crystallization is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
