Adjustable plastic bottle winnowing device

Abstract

The invention discloses an adjustable air separation device for plastic bottles, which comprises a conveyor belt, a holding tank, a blower and a bottle conveying pipe; the conveyor belt transports weighed plastic bottles into the holding tank; There is an air inlet, and the air inlet is equipped with an air intake control mechanism; the air inlet is connected to the storage tank, so that the strong wind blown by the blower can enter the storage tank to blow up the plastic bottle and blow it into the bottle delivery pipe, and from the outlet of the bottle delivery pipe fly out. The wind speed blown by the blower to the holding pool is controlled by the air intake volume control mechanism, so that the wind force can just blow away empty bottles, and heavy plastic bottles such as water or soil cannot be blown away and remain in the holding pool. An adjustable plastic bottle winnowing device of the present invention is capable of sorting plastic garbage bottles of different weights, thereby automatically sorting out bottles filled with water or adding sand and mud, and avoiding the impossibility of deducting the sundries in the bottles when weighing problems, simple structure, and good versatility.

Description

technical field [0001] The invention relates to a sorting device, in particular to an adjustable plastic bottle winnowing device for sorting and recovering garbage plastic bottles. Background technique [0002] At present, most beverage bottles on the market are plastic bottles. Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Polyester (PET), polyethylene (PE) and polypropylene (PP) are widely used as raw materials for plastic bottles. After adding corresponding organic solvents and heating at high temperature, plastic bottles are blown, extruded, or injection molded. plastic container. It is mainly used for liquid or solid disposable plastic packaging containers for beverages, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs, etc. Plastic bottles have the characteristics of unbreakable, low cost, high transparency, and food-grade raw materials. [0003] As ...
