Metal-containing garbage screening device

Abstract

The invention discloses a metal-containing garbage screening device, and relates to the technical field of machinery. The device comprises a conveying belt, the conveying belt is installed on a magnet block in a transmission mode, a sorting shell is arranged below the conveying belt, a slow falling block is fixedly embedded in the inner wall of the sorting shell, a splash-proof baffle is fixedly embedded in the outer wall of the bottom of the slow falling block, and a wave buffering plate is fixedly embedded in the inner wall of the sorting shell; the bottom of the wave buffering plate is fixedly embedded in the outer wall of the top of the device shell, and the top of the device shell is slidably installed on a blocking plate. According to the metal-containing garbage screening device, a first magnetic plate, a second magnetic plate and a third magnetic plate are arranged, the first magnetic plate can effectively slow down the falling speed of iron products so that the iron products can be separated from waste residues and garbage, and meanwhile deodorization treatment can be effectively conducted through gas exchange generated by movement of the second magnetic plate and the third magnetic plate; and in addition, the gas flows through the arc-shaped sheet tubes, the effect of accelerating falling of waste residues and garbage can be achieved, and the separation efficiency of iron products and garbage is improved.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a screening device for metal-containing garbage. Background technique [0002] Garbage pollution is a phenomenon that garbage encroaches on land, blocks rivers and lakes, hinders sanitation, affects landscape, and endangers the growth of crops and human health. Garbage pollution can be divided into two categories: industrial waste pollution and domestic waste pollution. Industrial waste refers to the waste generated during industrial production and processing, mainly including coal gangue, fly ash, steel slag, blast furnace slag, red mud, plastic and petroleum waste. Household garbage is mainly kitchen garbage, waste plastics, waste paper, broken glass, metal products and so on. In cities, due to the continuous growth of population, domestic garbage is increasing at a rate of 10% per year, which constitutes a major public nuisance. [0003] In the prior art, during the was...

Problems solved by technology

[0003] In the prior art, during the waste treatment process, most of the industrial waste will be mixed with iron products, and the iron products will cause iron pollution during the waste treatment process, and the industrially produced iron products can be recycled. , if iron products are treated together with ordinary garbage, it will cause waste and pollution, which makes it necessary to effectively separate iron products from ordinary garbage
