The utility model discloses a vinyl carbonate purifying device which comprises a first transverse plate and vertical plates, wherein the upper surface of the first transverse plate is fixedly connected with the vertical plates, and a purifying device is arranged above the vertical plates. This ethylene carbonate purification device, through trapezoidal plate, a housing, the second diaphragm, mutually support between crystallizer and the otter board isotructure, can make the otter board intercept the ethylene carbonate that takes place the crystallization, make all the other mother liquors can continue downward flow simultaneously, thereby the putty has been prevented, through first gear, the second gear, the montant, first sheave, the belt, the second sheave, mutually support between motor and the third diaphragm isotructure, can make the motor drive the second sheave and rotate, the second sheave drives first sheave through the belt and rotates, first sheave drives the second gear through the montant and rotates, the second gear drives the crystallizer through first gear and rotates, thereby ethylene carbonate drops with higher speed, and then collection efficiency has been improved. |
