[0004] In the above-mentioned waste paper processing system, the structure of the unpacking machine is relatively simple, and it can only remove the impurities on the surface of the waste paper and between the waste papers. For the impurities wrapped in the corners of the waste paper bags, even if the rollers in the unpacking machine roll continuously, It is also difficult to remove; on the other hand, the waste paper treatment process in the above waste paper treatment system is simple, and the waste paper enters the pulping process after simple treatment such as crushing and dry dust removal, and the pulped waste paper becomes fibers. The specific surface area of the fiber is much larger than that of waste paper, and its surface has hydroxyl groups with strong adsorption effect. The hydroxyl groups and fine impurity particles adsorb each other, which is more difficult to remove in the subsequent screening and purification system.

Abstract
This application relates to a bulk bag dust removal device. The invention discloses a bulk bag dust removal device, which includes: a drum, the drum includes a feed port and a discharge port, and a first knife part is provided on the inner wall of the drum; and at least one rotating shaft, the rotating shaft At least a part of the shaft is located in the drum, and a second knife part is provided on the rotating shaft; wherein the first knife part and the second knife part rotate with the drum and the rotating shaft respectively. The bundled materials are broken up during the process, and the materials are further torn apart when they intersect each other in the drum. The bulk bag dust removal device provided by the present invention further removes impurities attached to materials through dry dust removal, thereby simplifying subsequent purification and screening processes.
Description
technical field [0001] The invention relates to the field of waste recovery and treatment, in particular to a bulk bag dedusting device. Background technique [0002] In the recycling of waste, it is necessary to take effective measures to remove impurities such as powder ash and particles in the waste. Taking waste paper recycling as an example, the recycled waste paper includes office waste paper, waste packing boxes, waste cement bags, etc. In order to realize the reuse of waste paper, it is necessary to remove the impurities in the waste paper as much as possible, so that the ash content of the waste paper pulp obtained later is close to that of the base paper (below 5%). [0003] Known waste paper treatment systems include conveyors (belt conveyors or chain conveyors), bulk balers and D-type hydropulpers. In the waste paper processing process, the waste paper first enters the unpacking machine through the conveyor, rolls and hits the drum of the unpacking machine and ...
