Technical Field

The utility model relates to a dust collector technical field specifically is a paper mill hydrapulper exhaust dust collector.

Background

In the paper industry, pulp making and paper making enterprises generally carry out pulp crushing in the pulp making production process, the first procedure is pulp crushing, waste paper raw materials are conveyed to a hydrapulper through a chain plate conveyor, a certain amount of white water is injected into the hydrapulper and rotates at a high speed through a hydrapulper rotor, a mixture of the waste paper and the white water in a groove body of the hydrapulper is sucked along the axis center and thrown out from the circumference at a high speed, and severe turbulent circulation is formed. Due to the tearing of the impeller wings and the mutual wetting of the pulp flow layers with different speeds, a huge friction effect is generated, so that the waste paper is strongly defibered and separated from the fibers in a wet state to form pulp. When the waste paper enters the pulper, a large amount of dust and wastepaper can be scattered through the stirring of the pulper, the generated dust and wastepaper can be attached to the dust removal device, and the working efficiency and the service life of the dust removal device can be influenced if the dust and wastepaper are not processed in time. Therefore, we improve the technology and propose a pulping machine exhaust dust removing device in a paper mill.
