Integrated energy-saving processing process for modified reprocessed plastic

Abstract

The invention provides an integrated energy-saving processing process for modified reprocessed plastic, relating to the technical field of resource reutilization. The integrated energy-saving processing process comprises the following process steps: (1) cutting waste storage batteries and sequentially separating plastic pieces, grids, lead plaster, lead powder and the like in the waste storage batteries out; (2) putting the separated plastic pieces into washing equipment and washing; after the washing, leaching and conveying the separated plastic pieces into disinfection equipment and disinfecting the separated plastic pieces; (3) putting the disinfected plastic pieces into a crusher, crushing the disinfected plastic pieces into grains and quantitatively adding the plastic grains into an extruder and adding other auxiliary materials according to the requirements on preparation of a product; extruding by the extruder; and (4) directly putting plastic strips extruded by the extruder into a molding mould, and de-molding to directly obtain a finished product; and carrying out surface treatment on the finished product. According to the integrated energy-saving processing process, four links of drawing wires, cooling, granulating and refusing are reduced; compared with a traditional process, the integrated energy-saving processing process has the advantages that energy-saving and environment-friendly effects are achieved; the processing efficiency is improved and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of resource reuse, in particular to an integrated energy-saving processing technology for modified recycled plastics. Background technique [0002] At present, the batteries used in automobiles and electric bicycles are mainly lead-acid batteries, which are low in cost and simple in manufacturing process, and occupy a dominant position in the electric bicycle market. In 2011, the national output of lead-acid batteries has reached 240 million kVAh. The service life of lead-acid batteries for automobiles and electric bicycles is one and a half to two years. Although the quality is strictly controlled according to the process during production, many batteries will age after half a year, which will shorten their service life. The number of lead-acid batteries of waste cars and electric bicycles is increasing year by year, and the total amount is huge, which has a great impact on the environment. [0003] In ord...

Problems solved by technology

Recycled plastics prepared by traditional recycling methods need to be melted, extruded, drawn, cooled, cut, granulated and other process steps. When reprocessing, more plastic particles are required to be melted again. The process steps are cumbersome, resource consumption is high, and the cost is high.
