Centrifugal magnetic separation iron removal device for construction waste

Abstract

The invention discloses a centrifugal magnetic separation iron removal device for construction waste. The centrifugal magnetic separation iron removal device comprises a base substrate and a materialcollection tank. A strip-shaped supporting groove with a crossed cross section is formed in the end face of a supporting top plate. A supporting sliding block matched with the strip-shaped supportinggroove and connected with the strip-shaped supporting groove in a left-right sliding manner is installed in the strip-shaped supporting groove. Two spiral suspenders and two limiting guide rods penetrate the supporting sliding block. Multiple iron sleeves are distributed on the side wall of a rotating vertical shaft. Electromagnetic iron bars are mounted on the inner sides of the iron sleeves. A transverse movement screw sleeve matched with a transverse movement screw rod is mounted on the transverse movement screw rod. A rotating sleeve is rotationally mounted on a supporting cross plate through a bearing. A limiting sliding sleeve is arranged on the supporting cross plate. The device is simple in structure, capable of repeatedly removing iron from waste materials, high in removal rate, convenient to operate, capable of completely separating iron from waste materials, controlled by the motor drive, easy to operate and high in practicability.

Description

technical field [0001] The invention relates to a garbage sorting and iron removal device, in particular to a construction waste centrifugal magnetic separation iron removal device. Background technique [0002] Municipal domestic waste often contains scrap iron items, and the existing waste disposal often includes landfill and incineration. During the landfill process, iron-containing items are oxidized and decomposed to form water containing iron salts, which is difficult to treat landfill leachate; in the process of waste incineration, the calorific value of iron-containing waste is low, and incineration needs to consume heat, resulting in a large amount of furnace waste. Dust will also produce secondary air pollution. Scrap iron-containing items can be recycled, and iron-containing items need to be sorted out before recycling. The existing iron removal method is to sort the iron material by manually turning the garbage through the clamping device or dumping the garbage...

AI Technical Summary

Problems solved by technology

The existing iron removal method is to sort the iron material by manually turning the garbage through the clamping device or dumping the garbage on an inclined magnet for sorting. Manually turning the garbage to remove iron requires a large labor force, low efficiency, and small iron. It is troublesome to take out the material, and the inclined magnet method, the garbage is easily covered by the iron material on the magnet, and it is more troublesome to clean up
