Shell-shaped material centrifugal dehydrator

The invention provides a shell-shaped material centrifugal dehydrator which comprises an outer shell (9), rotors (13, 15), a mesh basket barrel (14) and a motor, wherein main shafts of the rotors are connected with the motor through transmission mechanisms, the mesh basket barrel is installed on circumferential positions along the main shafts of the rotors, and a rotation shaft (18) of the mesh basket barrel is connected with the rotors through a rotation drive mechanism. Compared with the prior art, the rotation drive mechanism is arranged between the rotation shaft of the mesh basket barrel and each rotor, the rotation shaft of the mesh basket barrel can rotate relative to the rotor, and when the main shafts drive the rotors to rotate, the mesh basket barrel revolutes around the main shafts and also autorotates around the rotation shaft. With the autorotation of the mesh basket barrel, shell-shaped materials in the mesh basket barrel can be detached from the centrifugal force of the rotors because of variat
