Equipment for classifying and recovering metals from construction waste

Abstract

The invention relates to the field of construction waste classification and recovery, in particular to equipment for classifying and recovering metals from construction waste. The equipment comprisesa shell, a crushing mechanism, a classification mechanism, a conveying mechanism, a separating mechanism and a supporting mechanism, wherein the conveying mechanism is horizontally arranged, the separating mechanism is vertically arranged, the supporting mechanism is vertically arranged, the crushing mechanism comprises a feeding chamber, a crushing chamber, a discharging chamber, a first crushingwheel, a second crushing wheel, a first motor, a second motor, a port, a first funnel plate and a second funnel plate, the first motor and the second motor are both horizontally arranged, and the classification mechanism comprises a first inclined plate, attracting blades and a third motor. According to the equipment for classifying and recovering the metals from the construction waste, the construction waste can be quickly crushed, the crushed construction waste is classified according to the permeability and non-permeability property, and then is classified according to the metal and non-metal property, the construction waste is classified clearly, the recovering rate is high, the operation steps are simplified, and safety and environmental protection are realized.

Description

technical field [0001] The invention relates to the field of classification and recycling of construction waste, in particular to a device for classifying and recycling metals from construction waste. Background technique [0002] With the acceleration of urbanization and the continuous development of the economy, the city has accelerated the speed of "metabolism", and a large number of old buildings have been demolished. In this process, construction waste has virtually become a "metabolite" that hinders urban construction. How to deal with these construction wastes is a social issue that deserves more and more attention. Urban construction waste mainly includes excavation waste generated by the urban construction department to build new buildings, waste generated by demolition projects, and road construction and maintenance processes. Waste, etc. Although most construction waste is non-toxic and harmless, if it is simply landfilled, it will not only affect the urban enviro...

AI Technical Summary

Problems solved by technology

[0008] There are a lot of metal products in some of the construction waste, which can be recycled after treatment. Some existing equipment is relatively simple when processing construction waste. When recycling construction waste metal, it can only be used for simple waste. Metals are recycled, nails on some wood and various metals cannot be recycled, metals on some waste products cannot be separated, resulting in incomplete recycling of construction waste, unreasonable r
