Defibering, paving and screening device and method for recycled materials

Abstract

The invention discloses a defibering, paving and screening device and a defibering, paving and screening method for recycled materials. The device comprises a plurality of scattering units arranged together; each scattering unit comprises a rotating shaft, a helical blade arranged on the rotating shaft and a tearing unit arranged on the rotating shaft; the device further comprises a driving mechanism used for driving the rotating shaft to rotate; the helical blade is formed by a levorotation blade and a dextrorotation blade; the levorotation blade is arranged between the middle of the rotating shaft and one end part of the rotating shaft; the dextrorotation blade is arranged between the middle of the rotating shaft and the other end part of the rotating shaft; and a boundary zone is formed at the junction part of the levorotation blade and the dextrorotation blade. The device not only can scatter materials, but also can pave the material in the axial direction, so that the material can be sufficiently scattered and the scattered material can be uniformed paved, thus being favorable for screening of different materials and sufficient exposure and removal of impurities; and meanwhile, materials with different sizes and shapes can be screened during scattering, thus playing a role of screening materials.

Description

technical field [0001] The present invention relates to a recycling and processing equipment and method for renewable resources, in particular to a device and method for unwinding, paving and screening recycled materials, such as recycled papermaking scum, polluted braids, domestic waste recycling, etc. . Background technique [0002] In the recycling process of renewable resources (such as regeneration of recycled paper residues, contaminated woven fabrics, regeneration and recycling of agricultural films, recycling of domestic waste and recycled materials, etc.), the materials to be processed enter a specific Before the treatment process, due to factors such as material packaging, transportation, pre-treatment process requirements or due to the characteristics of the material itself, the material is usually entangled and agglomerated with other impurities, for example, recycled papermaking tailings before rinsing, after dehydration Compacted materials, domestic waste wrap...

AI Technical Summary

Problems solved by technology

[0005] 1. When working, the tearing piece breaks up the material in the circumferential direction of the rotating shaft and pushes the material forward, but there is no material transfer in the axial direction of the rotating shaft, which leads to uneven distribution of materials in the axial direction of the rotating shaft Uniform, usually showing that the material at the corresponding part of the feeding part is thicker, so that the material cannot be fully dispersed, and there is a partial accumulation of the dispersed material, which is not conducive to the sorting of the material and the full exposure and removal of impurities

[0006] 2. The existing material disintegration device only plays the role of breaking up, not screening, and all the materials after breaking up are still mixed together

[0007] However, the bouncing sieve only has multi-directional reciprocating motion to screen the materials; however, the wrapped materials cannot be torn apart without strong external force, and the purpose of fully exposing and screening cannot be achieved.
