Description

Technical Field

[0001] This utility model relates to the field of impurity removal technology for rotary drum pulpers, and in particular to an impurity removal device for rotary drum pulpers. Background Technology

[0002] The drum pulper is a replacement for the traditional hydraulic pulper. The main structure of this equipment is a slightly angled rotating drum device from the feed end to the discharge end. The front section of this device is the pulping zone, and the rear section is the screening zone. During operation, the drum rotates at a certain speed. Waste paper, water, and suitable chemicals are continuously added from one end of the drum and mixed together. Inside the drum, the lifting plates continuously scoop up and drop the wet waste paper, slowly moving it from the pulping zone towards the screening zone. The impact and friction generated by this action can "gently" break down the waste paper fibers while maintaining their strength relatively well; simultaneously, the friction and tumbling collision between fibers can efficiently peel ink particles, films, and hot melt adhesives from the fiber surface. The pulping effect, i.e., the degree of dispersion, depends on the raw materials, the type of chemicals used, the pulping time, and the intensity.

[0003] CN 211471940 U discloses a dust removal device for a rotary drum pulper, comprising a rotary drum body. The rotary drum body includes a pre-impregnation cylinder, a pulverizing cylinder, and a screening cylinder connected sequentially from left to right. A main pre-impregnation lifting plate and a secondary pre-impregnation lifting plate are evenly distributed on the inner wall of the pre-impregnation cylinder, and the main and secondary pre-impregnation lifting plates are staggered in both the circumferential and axial directions. A main pulverizing lifting plate and a secondary pulverizing lifting plate are evenly distributed on the inner wall of the pulverizing cylinder.
