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.

Abstract: An automatic sand abrasion device includes a shell, an integrated framework, a sand falling mechanism, a sand transport mechanism, a sand falling channel, a sample working frame and a circuit control cabinet, where the device adopts the transport belt and the second speed reduction motor to realize transportation of sand, and realizes that the weighed sand falls into the bottom of the abrasion device through the first speed reduction motor and the automatic weighing machine. The whole process can be automatically operated while parameters such as the operation time and the weight of abrasion sand are set, so that the detection efficiency for the abrasion resistance can be improved, and the labor cost is greatly reduced. The device is firm in structure and stable and reliable in work and improves the accuracy and efficiency of an experiment.
