Description

[0002] In the production and processing of petroleum coke, it is often necessary to blend petroleum coke with other powders to meet specific process requirements. However, during the blending process, the collection and treatment of powders has become an urgent problem to be solved. Traditional powder collection devices often have problems such as poor filtering effect, powder residue, uneven heating of the electric heating plate, and blockage caused by high powder viscosity, which seriously affect the quality and production efficiency of petroleum coke blended powder. Specifically, traditional powder collection devices usually adopt a fixed filtering structure, which cannot effectively filter powder and air in layers, resulting in poor filtering effect and serious powder residue. At the same time, the design of the electric heating plate is often not reasonable enough, and the heating is uneven, which makes the drying effect of the powder unsatisfactory. The viscosity is too high, and it is easy to get blocked when entering the pump and filter.
