Description

A garbage classification collection and transportation system based on pneumatic conveying

technical field

The utility model relates to a vehicle for classified collection and transportation of garbage, which is used for classified collection, cleaning and transportation of garbage, and belongs to the technical field of urban environmental sanitation.

Background technique

In my country's municipal solid waste, there are many recyclable resources. Reasonable recycling and use of municipal waste can create greater value, which has far-reaching significance for resource utilization and environmental protection. Garbage classification and recycling are mainly divided into the following four categories: recyclables, hazardous waste, kitchen waste and other waste. However, my country's current garbage sorting mechanism is not perfect, and the sanitation system is out of touch in terms of garbage sorting facilities and operation management. The main problems are as follows: (1) Although the state vigorously advocates garbage sorting, most of them are mixed in the process of garbage truck transfer and recycling. On the one hand, garbage sorting becomes "empty talk", on the other hand, the utilization rate of useful garbage is low. Low, which is a waste of resources; (2) The trash cans used on urban roads are mostly split, and there is a certain gap between the outer shell and the inner tube of the split trash can, and the garbage is easy to be thrown out of the tube; (3) Urban The garbage collection process in roads, parks, and campuses mainly relies on manual cleaning, which is labor-intensive and inefficient, and garbage is scattered during the garbage dumping process; (4) The stubborn stains inside the garbage cans are difficult to clean thoroughly, which breeds bacteria and Corrosion damages the trash can easily. In response to the above problems, this patent designs a garbage removal vehicle and garbage can based on pneumatic conveying technology, which aims to solve the shortcomings of the traditional garbage can split structure, as well as the unsorted treatment of garbage during the vehicle transfer process, and the labor intensity of manual cleaning. Problems such as low efficiency and residual stains in the trash can. At the same time, the non-contact method realizes the recycling and transshipment of garbage, which greatly reduces the probability of personnel being infected with diseases.
