National and provincial code:
CN330402
Abstract:
The utility model discloses a flash dryer for drying zinc p-toluenesulfonate, which belongs to the technical field of dryer equipment, and comprises a bracket, a tank body and a feed pipe, and a bracket is installed on the surface of the tank body, the top of the surface of one side wall of the tank body is embedded with a feeding pipe, both sides of the bottom surface of the tank body are equipped with a driving motor, the inner cavity of the tank body is equipped with a stirring paddle, and the stirring paddle is connected to the input end of the driving motor through a rotating shaft. The utility model can form a powerful rotating wind field in the tank body through multiple groups of driving motors and stirring blades, and the hot air is injected into the tank body, so that the material can be dried and dehydrated, in addition, the dehydrated material can be discharged with the rise of the hot air flow. Through the anti-adhesive coating and the thermal insulation cotton, the material can be prevented from sticking to the inner wall surface of the tank body, and the heat preservation effect can be achieved, at the same time through the sewage pipe, and can be discharged after cleaning the sewage, improve the service life of the flash dryer.
