Abstract
The utility model relates to a novel pneumatic dryer for preparing an oil-refining catalyst. An anti-sticking wall and a static gas applicator capable of reinforcing the uniform distribution of hot gas are mounted at the bottom of the pneumatic dryer. The static gas applicator is a duplex spiral-case structure with a tangential outward rotating wind inlet and an inward rotating wind inlet and the hot gas in the outward rotating spiral-case complements the decrement of the hot gas in the spiral-case due to the forepart gas flow bottom circular gap, thus the hot gas wind-speed in the inward rotating spiral-case is reinforced to be favorable for homogenizing the distribution of the hot gas. A static accelerator in the center of the duplex spiral-case accelerates the material rotate and ascend and a pottery clearance ring is arranged in a pneumatic drying tube to prevent the tube wall from adhering the material and the tangential force of the rotating and ascending of the material is large to forcedly break the material falling into the bottom of the pneumatic drying tube and the granularity of the broken material is also uniform due to the uniform distribution of the hot gas, so as to conquer the defects of the existing technology that the material grains are not uniformly dried and the transmission device easily generates mechanical failure.
