Method and device for separate collecting middle sized garbage

Abstract

The present invention is one kind of middle-sized garbage sorting and recovering method and apparatus. Wind force and water power are utilized to separate bottle and jar, floated matter, semi-floated matter, etc. from garbage while washing garbage.

Description

technical field [0001] The invention relates to a method and device for sorting and recycling medium-sized garbage, in particular to a method and device for quickly and effectively separating and collecting flake-shaped plastics in garbage. Background technique [0002] Since ancient times, the way to deal with garbage is nothing more than landfill and incineration. However, with the progress of society, the amount of garbage produced by people is very large, resulting in the need to use a large amount of land to bury garbage. It is not good, and it is easy to further cause groundwater and soil pollution; while incineration will generate a lot of air pollution, and the incinerated slag will eventually be buried in the ground, which will also cause groundwater and land pollution problems; Moreover, with the development of new cities and towns, people pay more attention to the environment of their homes, which leads to a struggle against the establishment of garbage sites, whi...

Problems solved by technology

[0004] However, the current recycling equipment and technology cannot effectively classify mixed garbage. The key point is that the substances in domestic waste are too complex, including toxic, non-toxic, large, small, dry, wet, soft, hard and light, Substances with different weights are usually unable to be effectively classified by mechanized equipment; and the method of manual classification (may be required to be classified by the public first or sorted by recycling personnel afterwards), is troublesome and has a high error rate in classification. Once toxic substances are mixed in the garbage, the manual sorting method will easily cause people to be infected by toxic substances, and it is not an ideal sorting method

[0005] In particular, there may be mixed cotton products, aluminum and iron cans, plastic sheets, and foaming objects in the garbage, which are often stuck together with other garbage, and because it needs to be picked up and sorted manually, compared with general garbage It is more time-consuming and troublesome, and some cotton product waste or bottle waste is more likely to contain toxic substances, which is more likely to cause infection of cleaning staff

[0006] For this reason, Japan's open patent publication 2000-107699 (application number special wish flat 11-155675) "waste sorting and processing device" is provided to solve the above-mentioned processing. Although its conception is good, this case can only be used for large-scale Waste and small waste are screened by a vibrating screen. Fine waste such as small sand and gravel particles can pass through the vibrating screen and fall into the conveyor belt below the vibrating screen to be removed, but it cannot be removed for medium and large or even small and medium-sized waste Moreover, the next step in this case is to use the wind force to sort the waste and garbage, so that the light and heavy garbage can be sorted by wind and inclined vibrating screens and removed from different conveyor belts. There are too many types of garbage, such as sundries, bottles, cans, floating objects, semi-floating objects, plastic bags containing garbage, etc. The screening device cannot be subdivided, so the selection of light and heavy garbage in this case is not too rough, resulting in garbage The classification is not complete and needs further improvement
