  • Patent number: 11964888
    Abstract: Disclosed is a circular rotary-disc dehydrator with a multi-filter cylinder unit. A dehydrator body is internally provided with a middle plate so that the dehydrator body is separated into a water entrance area and a filtrate area. One side, located in the filtrate area, of the middle plate is provided with a circular rotary disc, a circle of holes is arranged around the circular rotary disc, and one side of the circular rotary disc is provided with a filter cylinder corresponding to the holes; The circular rotary disc is arranged in the filtrate area, and a plurality of filter cylinder units are uniformly distributed on the rotary disc. In the rotation process, it may be fed continuously and sludge may be discharged continuously; the filter cylinders have a self-cleaning function, and consume less water, thus not only the production is increased, but also the dehydrating effect is guaranteed.
