Metal screening and recycling device for building waste treatment and utilization

Abstract

The invention relates to the technical field of waste treatment, and discloses a metal screening and recycling device for building waste treatment and utilization. The device comprises a rotating shaft, a square-column-shaped rotating roller is fixedly mounted on the rotating shaft, four arc-shaped baffles are symmetrically arranged at four corners of the rotating roller, protective boxes are uniformly distributed on the rotating roller and the baffles, the protective boxes are fixedly equipped with electromagnet devices, sealing plates are fixedly arranged at the two sides of the four baffles, limiting frames are symmetrically installed on the two sides of the rotating shaft, the rotating shaft is movably installed in the limiting frames through shaft sleeves, the top ends of the shaft sleeves are connected with the tops of the limiting frames through telescopic rods, the telescopic rods are sleeved with first springs, a driven wheel is fixedly installed at one end of the rotating shaft, and a cam is arranged under the driven wheel. Metal waste can be screened from crushed building waste, and the vibration screening effect is achieved; and automatic discharging can be achieved, so that the screening efficiency is greatly improved, and energy and time are saved.

Description

technical field [0001] The invention relates to the technical field of waste treatment, in particular to a metal screening and recovery device for the treatment and utilization of construction waste. Background technique [0002] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the resulting construction waste is also increasing. If the construction waste generated is ignored for a long time, then our urban environmental sanitation, living environment and Land quality and so on have a bad influence. [0003] Most of the existing construction waste treatment is to crush the reinforced concrete through the crushing device and then process the waste slag. There are a lot of scrap metal in the crushed waste slag. If the scrap metal in the waste slag can be recycled, then It will save a lot of resources, but most of the existing screening devices are difficult to effectively recycle scrap metal, the screen is ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a metal screening and recovery device for construction waste treatment and utilization, which has the advantages of high automation, effective screening and recovery of scrap metal, automatic feeding, and the screen is not easy to block, etc. , which solves the problems of the traditional screening device, such as easy blockage of the screen, inconvenient feeding, and complicated operation.
