Description

Bulk dust removal device

Technical field

The invention relates to the field of waste recycling and treatment, and in particular to a bulk dust removal device.

Background technique

In the recycling of waste, effective measures are needed to remove impurities such as dust and particles in the waste. Taking waste paper recycling as an example, the recycled waste paper includes office waste paper, used packaging boxes, and waste cement bags. In order to realize the reuse of waste paper, it is necessary to remove impurities in the waste paper as much as possible, so that the ash content of the subsequently obtained waste paper pulp is close to the ash content (less than 5%) of the base paper.

Known waste paper processing systems include conveyors (belt or chain machines), bulk machines and D-type hydraulic pulpers. In the process of waste paper processing, the waste paper first enters the bulk wrapping machine through the conveyor, and is scattered after the tumbling impact in the drum of the bulk wrapping machine, and some impurities can be discharged through the mesh hole under the centrifugal force of the rotating drum. The scattered waste paper is output through a spiral belt in the drum and sent to a D-type hydraulic pulper through a conveyor. The D-type hydraulic pulper disintegrates the waste paper and discharges the non-decomposable impurities and enters the subsequent screening and purification system.

In the above-mentioned waste paper processing system, the structure of the bulk wrapping machine is relatively simple, and only the impurities entrained between the surface of the waste paper and the waste paper can be removed, and even if the impurities wrapped in the corners of the waste paper bag are continuously tumbling, the drum in the bulk wrapping machine continuously rolls. It is also difficult to remove; on the other hand, the waste paper processing process in the above waste paper processing system is simple, and the waste paper enters the pulping process after being simply processed by crushing, dry dust removal, etc., and the waste paper after pulping becomes fiber due to The specific surface area of the fiber is much larger than that of the waste paper. The surface has a strong adsorption hydroxyl group, and the hydroxyl group and the fine impurity particles adsorb each other, which is more difficult to remove in the subsequent screening and purification system.
