Embodiment 1

[0036] refer to figure 1 A method for crushing and recycling waste wood-plastic composite materials, comprising the following steps:

[0037] S1. Collect waste and old wood-plastic materials, and carry out preliminary cleaning on the collected waste and old wood-plastic materials. The preliminary cleaning includes preliminary segmentation and cleaning. The preliminary segmentation is to remove other materials on the waste and old wood-plastic materials by cutting machines, and clean them. Rinse with high-pressure water to cut and rinse the recovered waste wood-plastic materials, which can effectively improve the purity of waste wood-plastic materials, thereby avoiding debris remaining on waste wood-plastic materials, which is conducive to improving the efficiency and quality of processing. ;

[0038] S2. The cleaned waste wood-plastic materials are transported by clamping and feeding conveying machinery, and the clamping and feeding conveying machinery can stably transmit was...

Embodiment 2

[0046] refer to Figure 2-8 , the crushing and recycling processing method of waste wood-plastic composite materials, using a low-temperature impact crushing device for waste wood-plastic materials, the low-temperature impact crushing device for waste wood-plastic materials has a liquid nitrogen processing bin 22, and the upper end of the liquid nitrogen processing bin 22 runs through A second connecting pipe 24 is provided, the lower end of the second connecting pipe 24 is connected with a spray plate 33, and one end of the second connecting pipe 24 is connected with a liquid nitrogen storage tank 20, so that the liquid nitrogen in the liquid nitrogen storage tank 20 can pass through the second The connecting pipe 24 and the spray plate 33 enter the liquid nitrogen storage tank 20, thereby facilitating cooling of the material, increasing the brittleness of the material, and facilitating crushing;

[0047] One side of the liquid nitrogen storage tank 20 is provided with a pre-...

Abstract

The invention discloses a crushing and recovery processing method of waste wood-plastic composite. The crushing and recovery processing method comprises the following steps: S1, collecting waste wood-plastic material and carrying out primary cleaning on the collected waste wood-plastic material to prevent sundries from being left on the waste wood-plastic material; and S2, adopting a clamping feeding transmission machinery to transmit the cleaned waste wood-plastic material. The clamping feeding transmission machinery can stably transmit the waste wood-plastic material, so that a transverse sawing machinery and a longitudinal sawing machinery can conveniently cut the waste wood-plastic material. With adoption of the crushing and recovery processing method, the waste wood-plastic material can be cut to facilitate transportation and crushing; liquid nitrogen is adopted for cooling to effectively improve the processing efficiency and quality, so that the brittleness of the waste wood-plastic material can be greatly improved to further reduce power required by crushing, energy consumption and noise effectively.

Description

technical field [0001] The invention belongs to the field of composite materials, in particular to the technical field of recycling wood-plastic composite materials, and relates to a crushing, recycling and processing method for 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 processi...
