Description

Waste recycling and conveying device and using method for EPE rim charge recycling Technical Field The invention relates to the technical field of EPE waste recovery, in particular to a waste recovery conveying device and a use method for EPE rim charge recovery. Background EPE (expandable polyethylene), also known as pearl wool, is a widely used cushioning packaging material with excellent characteristics of light weight, flexibility, impact resistance, heat insulation and the like. In the production and processing process, a large amount of leftover materials are generated, and the recycling and reprocessing of the EPE materials is particularly important for realizing the recycling of resources, reducing the production cost and reducing the environmental pollution. Typical recycling processes include waste collection, transportation, compaction (or precompression), comminution, melt granulation, and the like. In the prior art, the recycling and conveying of EPE waste materials usually adopts a single conveying belt or a manual feeding mode to guide the waste materials to enter a pulverizer for pulverizing treatment, however, because the EPE material has extremely high bulk and elasticity, when the waste materials are conveyed to a feed inlet of the pulverizer through the single conveying belt, bridging, winding and blocking of the raw materials are extremely easy to occur, and the intermittent blanking is caused, so that the fluctuation of the working load of the pulverizer is severe, idling or overload shutdown frequently occurs, and the continuity and the treatment efficiency of a recycling line are seriously affected. In order to solve the above problems, some improvement schemes of adopting double conveying belts (up-down arrangement) appear in the prior art, and the waste is primarily compacted and then conveyed through extrusion between two conveying belts, however, because the initial thickness of the EPE waste to be treated is different and is often larger than a preset double-belt gap, when the ultra-thick fluffy waste is conveyed to the gap inlet, the ultra-thick fluffy waste can be instantaneously accumulated in front of the inlet due to the fact that the ultra-thick fluffy waste cannot timely enter, the accumulation cannot form effective compaction, and can quickly evolve into serious blockage to cause complete interruption of conveying and need shutdown cleaning.
