Crushing and recovery device special for high-strength waste wood-plastic composite materials

Abstract

The invention discloses a crushing and recovery device special for high-strength waste wood-plastic composite materials. The crushing and recovery device is constituted by a feeding conveying machine,a sawing machine, precooling equipment, low-temperature treatment equipment, a cold source and an impact crushing machine. The wood-plastic composite materials are treated by the precooling equipmentand the low-temperature treatment equipment and then enter the impact crushing machine to be subjected to impact crushing. A material backhaul machine and packing equipment are further connected to material screening equipment, and the material backhaul machine is further connected with the precooling equipment. According to the crushing and recovery device special for the high-strength waste wood-plastic composite materials, the wood-plastic composite materials can be recovered more conveniently, the large wood-plastic composite materials are cut into small pieces, thus cooling is facilitated, the brittleness of the materials can be improved, and the materials are crushed into particles conveniently; and the crushed materials can be screened, the unqualified materials are treated conveniently again, thus the reutilization rate of the materials is increased, the qualified materials can be packed, and transferring is facilitated.

Description

technical field [0001] The invention relates to the technical field of recycling wood-plastic composite materials, in particular to a special crushing and recycling device for high-strength waste wood-plastic composite materials. Background technique [0002] Wood-plastic composite material is regarded as a recyclable environmentally friendly material, and its waste or damaged products can be "crushed" into granules and further recycled into new wood-plastic composite products. However, compared with plastic, wood-plastic composite materials have the dual advantages of wood and plastic, and can have higher strength and toughness after compounding. It is especially difficult to crush some high-strength wood-plastic composite materials. It needs to consume a lot of mechanical energy and generate huge noise. [0003] Wood-plastic composites are composite products of wood fiber materials and thermoplastics. In the usual mechanical processing and crushing of wood or other wood f...
