Air floating garbage winnowing machine

Abstract

The invention relates to an air floating garbage winnowing machine which comprises a bellows used for providing winnowing space, an air floating winnowing unit used for providing an air floating channel for garbage and winnowing in cooperation with the bellows, a feeding hopper with the bottom horizontal position of no lower than the air floating winnowing unit and used for feeding, and weight discharging units corresponding to the bottom and the rear portion of the bellows. A light material discharging unit is arranged at the side part of the bellows in cooperation with the air floating winnowing unit; and the air floating winnowing unit is arranged in cooperation with a controller. According to the air floating garbage winnowing machine, the defects of single winnowing and short wind receiving time of a traditional winnowing machine are overcome, and through combination of multiple air floatation and blowing two-way wind action, the material winnowing frequency is increased; the windreceiving time is greatly prolonged, and the entrainment effect is greatly reduced; the efficient winnowing is achieved; further refined separation of weights is achieved through regulation of equipment operation parameters according to the operation requirements, and further treatment and disposal of winnowing products are facilitated; the air floating garbage winnowing machine has the advantages of the simple structure, less moving components, easy manufacturing, and low failure rate.

Description

technical field [0001] The invention belongs to the technical field of conveying solid materials by air flow, or diffusing solid materials in air flow for sorting, and in particular relates to an air flotation type garbage winnowing machine. Background technique [0002] With the rapid development of my country's social economy, the generation of urban domestic waste is increasing day by day. According to statistics, the annual output of domestic waste in my country is about 250 million tons. , almost two-thirds of the 661 cities are surrounded by garbage. [0003] At present, domestic waste landfill treatment projects are increasing day by day, among which waste excavation and screening treatment is an important treatment method. [0004] In the prior art, for the mixed type of garbage with light and heavy materials, such as plastics, fabrics, stones and bricks, domestic garbage sorting and treatment mostly use air separators to separate; however, ordinary air separators ca...

AI Technical Summary

Problems solved by technology

[0006] The invention solves the problems in the prior art that the materials of the air separator can only be selected by air for a single time, the wind exposure time is short, the quality of material sorting is poor, and it can only be sorted into light and heavy materials, etc., and provides an optimized structure air flotation garbage winnowing machine
