Centrifugal dehydrator

The centrifugal dehydrator comprises a mounting cavity and a rotating cavity rotationally connected with the upper end of the mounting cavity, a partition plate is fixedly connected in the rotating cavity, a drying component is arranged in the rotating cavity, and the drying component comprises an air storage cavity, an air dispersing opening, an air inlet pipe, a piston and a driving shaft. Round holes are formed in the lower side wall of the rotating cavity and the upper side wall of the mounting cavity, the upper end of the driving shaft is rotationally connected to the upper side wall of the rotating cavity, the driving shaft is sleeved with the air storage cavity, reciprocating threads are formed in the driving shaft, and the piston is in threaded connection to the driving shaft and is slidably connected into the air storage cavity. When the driving gear rotates along with the rotating shaft, the driving gear can drive the rotating cavity to rotate through meshing connection with the gear ring, so that d
