Dust removing system for wood-plastic pelletizer

Abstract

The invention provides a dust removing system for a wood-plastic pelletizer. The dust removing system comprises a rack and a dust removing box body fixed to the rack. The dust removing system is characterized in that a dust gas inlet is formed in the position, located on the lower half part of the side face, of the dust removing box body; a clean gas outlet and a dust outlet are formed in the top and the bottom of the dust removing box body respectively; an air suction pipe is arranged at one end of the box body in the way of being in butt joint with the clean gas outlet, and the other end of the air suction pipe is connected with an air suction device; a plurality of keel frames arrayed in parallel are arranged in the dust removing box body, and each keel frame is sleeved with a dust removing filter bag. By means of optimized structure design, dust gas enters the interior of the dust removing box body from the dust gas inlet under the suction force action of the air suction device, the dust removing filter bags arranged inside the box removing box body conduct dust and gas separation on the dust gas, clean gas after separation is exhausted from the clean gas outlet, dust is discharged from the dust outlet, and by controlling the mesh number of the dust removing filter bags, the gas exhausted from the clean gas outlet can meet the emission standard stipulation of the nation with respect to gases which are harmless to human bodies and the atmosphere.

Description

technical field [0001] The invention belongs to the technical field of dust removal in industrial production, and in particular relates to a dust removal system for a wood pelletizer. Background technique [0002] The wood plastic granulator is used to produce wood-plastic particles used in board processing. The wood-plastic pellets are made by mixing wood powder and plastic powder through the wood plastic granulator based on the melt extrusion process, and then melted and extruded into large-sized particles. Through the cutting process, the large-size particles are cut into wood-plastic particles with particle sizes that meet the requirements, and finally the formed wood-plastic particles are blown into the silo by high-pressure air through the pipeline. A large amount of dust will be generated in the large particle size particle forming process and the cutting process of cutting large particle size particles into small particle size particles. The environment of the works...

Problems solved by technology

A large amount of dust will be generated in the large particle size particle forming process and the cutting process of cutting large particle size particles into small particle size particles. workshop or even outdoor atmospheric environment, therefore, there is an urgent need for a dust removal system used with wood pelletizers to solve the impact of dust generated during the production process on the environment
