Description

Devices for calcium carbide unloading, feeding and crushing

technical field

The invention relates to automation equipment for acetylene materials in the chlor-alkali industry, in particular to a device for unloading, feeding and crushing calcium carbide that can reduce production costs and improve the working environment of on-site operators.

Background technique

The production of vinyl chloride by the traditional calcium carbide method will inevitably consume a large amount of calcium carbide, and these calcium carbides are purchased and transported from other places to the company by car. The car loaded with calcium carbide is first driven into the calcium carbide shed (the shed is mainly for rain and snow protection) weather, because the calcium carbide meets water will produce acetylene gas, acetylene gas is flammable and explosive), and then use the loader to push the calcium carbide off the car, and use the loader to break the large calcium carbide to less than 400mm and send it to the primary jaw type Carbide is crushed at the feed port of the crusher, and finally transported to the fine crushing process for loading. There are problems in this mode of unloading, loading and crushing calcium carbide with loaders and primary jaw crushers: the unloading and crushing locations of calcium carbide are scattered , the calcium carbide dust is relatively large, and the working environment of the on-site operators is harsh, which is not conducive to the realization of fixed-point collection of calcium carbide dust; the particle size of calcium carbide entering the inlet of the primary jaw crusher must be below 400mm, otherwise the inlet of the primary jaw crusher will be blocked Material; the degree of automation is low, requiring a lot of manpower and vehicle cooperation, resulting in more labor costs, machinery costs, and repair costs; there are certain safety hazards, and the use of loaders to unload, break and load calcium carbide may cause mechanical damage.

Contents of the invention
