High-efficiency drying facility for coal chemical industry and with dust prevention function

Abstract

The invention relates to a high-efficiency drying facility for the coal chemical industry and with a dust prevention function. The high-efficiency drying facility comprises a body, a supporting plate and four supports, and further comprises a stirring mechanism and a dust preventing mechanism. The stirring mechanism comprises a first motor, a rotating shaft, a moving plate, a bearing, two driving assemblies, multiple connecting rods and multiple stirring assemblies. Each stirring assembly comprises a supporting shaft and a stirring plate. The dust preventing mechanism comprises an air suction assembly, a dust preventing box and a filtering screen. A shaking assembly is arranged inside the dust preventing box and comprises a power unit, a moving rod and two vibrating rods. The high-efficiency drying facility for the coal chemical industry and with the dust prevention function can conduct the stirring work on coal materials in the body through the stirring mechanism, the phenomenon that due to the fact that the coal materials are stacked together, the drying effect is affected is avoided, and the drying efficiency is improved; and the dust removal work can be conducted on the air of the body through the dust preventing mechanism, and the phenomenon that the dust is directly discharged into the atmosphere and affects the air environment is avoided.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to a high-efficiency drying equipment with dustproof function for coal chemical industry. Background technique [0002] Coal powder dryer is also called rotary drum desiccant, it is widely used in building materials, metallurgy, cement industry, coal mining industry to dry slag limestone, coal powder, slag, clay materials. The heat source of the pulverized coal dryer comes from the combustion device and adopts a downstream heating method. Therefore, the materials that need to be dried slip into the cylinder from the feed box and feed, and are pushed backward by the spiral lifting board. Due to the inclined placement of the dryer, on the one hand, the material flows to the back end under the action of gravity and rotation; The curtain fully exchanges heat with the hot air in the cylinder. As the material is repeatedly scattered, the moisture contained in it is gradually dried,...

AI Technical Summary

Problems solved by technology

[0003] When the existing drying equipment is drying, the coal powder is piled up together, resulting in uneven drying, which makes the drying of the coal powder insufficient and reduces the drying efficiency. Not only that, the existing drying equipment is When drying, it is easy to generate dust, and some coal powder is entrained in the dust. If the coal powder is directly discharged into the atmosphere, it will affect the surrounding air environment.
