Double-air compartment multifunctional winnowing machine used for municipal solid waste

Abstract

The present invention provides a double-air chamber multifunctional winnowing machine for municipal solid waste, which comprises a blower set, a first winnowing chamber, a second winnowing chamber, a vibrating screen, a rotary feeder, a scattering cylinder, a comb plate, and a cyclone dust collector. A first blower nozzle is led out from a blower to the first winnowing chamber. The rotary feeder is mounted at a feeding port of the first winnowing chamber. A heavy material discharge device is mounted below the first winnowing chamber and close to an air opening. The vibrating screen is mounted at a right side of the heavy material discharge device, and the vibrating screen is connected to the second winnowing chamber. A small inorganic material block discharge device is placed below the vibrating screen. A rear end of the first winnowing chamber is provided with the comb plate. Plastics and paper fall into a discharge device at a lower end of the comb plate. An air inlet of the second winnowing chamber is connected to the blower set. A kitchen waste discharge device is located at a lower end of the second winnowing chamber and close to the air opening. A rear end of the second winnowing chamber is provided with the comb plate. A plastics and paper discharge device is located at a lower part of the comb plate. The device can classify waste into five types, and has a high screening accuracy, and a wide application range.

Description

technical field [0001] The present invention relates to the field of municipal solid waste treatment, in particular to a multi-functional winnowing machine with double air chambers for municipal solid waste, especially an automatic, mechanized and intelligent sorting winnowing machine for sorting various wastes . technical background [0002] With the rapid development of the country's economy, the amount of municipal solid waste has increased dramatically. In 2010, the national urban domestic garbage removal volume reached 150 million tons, and the landfill and stacking of garbage occupied more than 800,000 mu of land. Two-thirds of the large and medium-sized cities in the country were surrounded by garbage, and one-quarter of the cities had already There is no suitable place for dumping garbage, and it is difficult to select a site and construct a new garbage dump. It is estimated that by 2020, the volume of municipal solid waste removal will reach 250 million tons, and ...

AI Technical Summary

Problems solved by technology

[0005] ①It is only for the purpose of sorting out plastic and paper light materials, and other materials in the garbage are landfilled, which wastes resources and brings environmental problems at the same time

Most of the air separators in China are only for the purpose of separating light materials such as plastics, and the structure is simple, which cannot achieve the purpose of garbage sorting

[0006] ② The structural design of the sorting machine only considers the density difference of different components of garbage, and ignores the influence of the particle size of different components of garbage. The purpose of separating the components

[0007] ③The waste gas from winnowing is not treated or recycled, and it is directly discharged to cause environmental pollution
