Waste recycling method and device

Abstract

The invention relates to the field of waste reutilization, in particular to a waste reutilization method and device.The waste reutilization method comprises the following steps that S1, straw is collected; s2, crushing the straws; s3, screening the straws; s4, respectively collecting straw stem particles and straw leaf fragments; the waste recycling device comprises a processing box, a feeding cover, a cutting mechanism, a centrifugal screening mechanism and a winnowing mechanism, the cutting mechanism is installed in the processing box and is close to one side of a feeding port, and the centrifugal screening mechanism and the winnowing mechanism are installed in the processing box. The cutter strip, the connecting frame and the scattering plate are matched to centrifugally scatter chopped straw particles and straw leaf fragments to the sieve plate to screen out small particles wrapped in the straw, meanwhile, the oppositely arranged air blowing cylinder and the collecting cover conduct convection winnowing on the fragments obtained after straw leaf smashing, waste straw is smashed and then collected in a classified mode, and therefore the waste straw can be recycled. And subsequent classification and utilization are facilitated.

Description

Technical field [0001] The present invention relates to the field of waste reuse, specifically a method and apparatus for using waste reuse. Background [0002] The amount of straw produced is larger, the traditional treatment method, the use of incineration back to the field, not only will cause serious environmental pollution, but also cause the straw utilization efficiency underground, straw can not only be used as an additive for feeding feed can also be used as a raw material for field fertilizer, but the straw raw material is not easy to use directly, the traditional use of the straw needs to be crushed and then reused. [0003] However, in the traditional post-crushing utilization method, the straw stem and the straw leaf are directly mixed together and utilized, which is not fully utilized and is not convenient for subsequent classification and processing. Contents of the Invention [0004] Based on the deficiencies in the prior art mentioned in the above background tec...

AI Technical Summary

Problems solved by technology

[0002] The amount of straw produced is relatively large. The traditional treatment method, which is incinerated and returned to the field, will not only cause serious environmental pollution, but also cause the efficiency of straw utilization to be lower. Straw can be used not only as an additive for feeding feed but also as a raw material for field retting , but the raw material of straw is not easy to use directly, the traditional way of utilization needs to crush the straw and then reuse it

[0003] However, in the traditional pulverized utilization method, the straw stems and straw leaves are directly mixed together for utilization, which is not fully utilized and is not convenient for subsequent classification, processing and utilization.
