Waste gas drying device for filling master batch

The utility model relates to a waste gas drying device for filling master batches, and relates to the technical field of plastic master batch production devices. Comprising a vibrating screen, a vibrating motor, a cyclone fan, an air pipe, a stock bin and a waste gas recovery assembly. One end of the air pipe is connected with the cyclone fan, the other end of the air pipe is connected with the stock bin, one end of the waste gas recovery assembly is communicated with the top of the stock bin, and the other end of the waste gas recovery assembly extends above the vibrating screen; and a blanking port of the vibrating screen corresponds to a feeding port connected to the air pipe. Waste gas generated after materials are conveyed to the stock bin through the cyclone fan is reused, filling master batches on the vibrating screen are dried through the waste gas with heat, the advantages of low manufacturing cost and attractive particle forming of the dewatering vibrating screen are combined, the stable dewatering
