Description

Plastic bottle recycling and cleaning equipment and using method thereof

Technical Field

The invention relates to the field of plastic bottle recycling and cleaning equipment, in particular to plastic bottle recycling and cleaning equipment and a using method thereof.

Background

The plastic bottle is mainly made of polyethylene or polypropylene and other materials with a plurality of organic solvents. The plastic bottle is a disposable plastic packaging container which is prepared by taking Polyester (PET), Polyethylene (PE) and polypropylene (PP) as raw materials, adding a corresponding organic solvent, heating at high temperature, and blow molding, extrusion blowing or injection molding through a plastic mold, and is mainly used for liquid or solid packaging containers such as beverages, foods, pickles, honey, dried fruits, edible oil, agricultural and veterinary medicines and the like. The plastic bottle has the characteristics of low breakage probability, low cost, high transparency, food-grade raw materials and the like.

As an artificial polymer material, plastic bottles generally have the characteristics of good corrosion resistance and slow degradation speed in natural environment, along with the development of environmental protection concept, plastics gradually change from the earliest products which are convenient for people to live to white pollution in the natural world, and under the consideration of environmental factors, more and more environmental protection manufacturers start the work of recycling the plastic bottles.

Present plastic bottle need clear up the work after retrieving, the filth of adhesion on the plastic bottle is fallen in the clearance, because the plastic bottle is mostly holding liquid article, in the convenient consideration of taking liquid article, its export is designed for small-mouth system usually, this just leads to the plastic bottle inner wall to be difficult to realize comprehensive clearance, consequently plastic bottle recovery work is usually after cutting the plastic bottle garrulous to clear up now, carrying out the hot melt shaping, can't directly carry out recycle, the recovery cost of plastic bottle has been increased.
