Sulfate drying device

The invention belongs to the technical field of drying equipment and discloses a sulfate drying device which comprises a drying tank, the top end of the drying tank is connected with a top plate through bolts, an adding assembly is fixedly installed on the left side of the top end of the top plate, an air pump is fixedly installed at the rear end of the drying tank, and a transmission air pipe is fixedly installed at the top end of the air pump. A sealing box is fixedly installed on the top face of the top plate, and an air channel is formed in the right side of the middle of the top plate. According to the device, gas is sprayed downwards from the spray heads to be in contact with sulfate above the placing plate, and the sulfate is pushed towards the side wall of the placing plate, so that the sulfate is blown away in the inner cavity of the placing plate along with gas flow, turbulent flow is generated, and the sulfate is spread by the gas flow; and the phenomenon that in the prior art, sulfate is compacted
