An equipment for producing plastic wood from waste plastics and plastic waste

Abstract

The invention discloses a device for producing plastic wood with waste plastics and plastic garbage as raw materials, including a feeding system, a heating extrusion system, a circulating water cooling system and a heat energy recovery raw material preheating system; the feeding system sends the raw materials to the heating extrusion system The heating extrusion system extrudes the melted raw materials and sends them into the molding die; the circulating water cooling system cools and solidifies the products of the extrusion die; the heat energy recovery raw material preheating system absorbs the heat from the heating extrusion system and the circulating water cooling system Preheating of raw materials. The equipment can directly digest all kinds of mixed waste plastics and can fuse no more than 30% impurities to produce plastic profiles, which greatly reduces equipment investment and labor costs compared with waste plastic granulation and recycling methods; the equipment has a large extrusion capacity, The extrusion speed is fast and the output is high, which can effectively eliminate the plastic smell during production. The heat energy collected can be used to preheat the raw materials to better save energy and reduce emissions.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization equipment, and relates to comprehensive utilization equipment for plastics, in particular to equipment for producing plastic wood. Background technique [0002] While humans are widely producing and utilizing plastic products, eliminating plastic waste has gradually become a thorny issue. Today, eliminating "white pollution" is the general trend of environmental protection. [0003] The traditional waste plastic processing equipment is a single plastic processing equipment, and the waste plastics are melted and granulated on the basis of manual sorting and cleaning according to different polymers to obtain plastic granules; if other products need to be prepared, it is necessary to After re-melting the plastic particles, it is prepared by other equipment; this not only increases the process and equipment, but also increases the cost of recycling and processing due to the existenc...
