Description

Rotary valve suitable for calcium carbide dust transport

Technical Field

The utility model belongs to the technical field of rotary valves, and particularly relates to a rotary valve suitable for conveying calcium carbide dust.

Background

In the process of producing vinyl chloride monomer by the calcium carbide method, the outsourced blocky calcium carbide is used as the initial raw material for production. On one hand, a large amount of calcium carbide dust can be generated in the outsourcing calcium carbide crushing process, and on the other hand, the crushed calcium carbide is entrained with the calcium carbide dust in the conveying and feeding processes, so that a large amount of dust emission is formed. After the dust is collected mainly through the bag filter type dust remover, the dust is regularly discharged to the dust conveying reamer through the bottom rotary valve, the dust is conveyed to the conveying belt through the reamer, and then the dust is added into the generator along the belt for use, so that the pollution of calcium carbide dust to the surrounding environment is avoided.

The existing dust removing bottom ash discharging rotary valve is rough in structure, the rotor is of a six-equal structure, and the discharging amount of calcium carbide dust is large, so that stable control of the generator is not facilitated; and the clearance between the rotor and the valve shell is larger, calcium carbide dust is easy to leak into the ash conveying reamer from the clearance, the ash discharging amount is further increased, and overload locking of the reamer is extremely easy to cause.

Therefore, we propose a rotary valve suitable for conveying calcium carbide dust to solve the above problems.
