An electromagnetic hot-melt reinforced concrete separation device and its application method

Abstract

The invention discloses an electromagnetic hot-melt type reinforced concrete separating device and a method for using the same, comprising an electromagnetic hot-melt type silent and dust-free separating device, a non-powered self-pretightening high-temperature heat-resistant driving device, a lifting base assembly and a cage-type anti-separation device. deposition stage. The invention belongs to the technical field of reinforced concrete recovery and separation, and specifically refers to an electromagnetic hot-melt reinforced concrete separation device and its use method; the invention melts and flows out the steel bars mixed in the concrete by means of electromagnetic heating, and overcomes the coagulation of the steel bars The technical bias that can only be separated by crushing and screening, through the swing device driven by the waste heat radiated from the molten iron, solves the problem that the molten iron in the horizontal hole is easy to deposit and cannot flow out. The pre-tightened sealing sheet effectively solves the problems of high energy consumption, high noise, dust and pollution in the current reinforced concrete separation device.

Description

technical field [0001] The invention belongs to the technical field of reinforced concrete recovery and separation, and specifically refers to an electromagnetic hot-melt type reinforced concrete separation device and a using method thereof. Background technique [0002] The mixture of concrete and steel bars is a common type of construction waste. Concrete can be used as a landfill material, while steel bars can be smelted and used after recycling. The process of separating concrete and steel bars is the first step in the green recycling of such materials. [0003] Because concrete is hard and brittle, almost elastic and plastically deformed, most of the current reinforced concrete separation devices are crushed and then screened. However, the strength of concrete is high, and it not only needs to consume a lot of energy when broken, but also will be accompanied by huge Noise and a large amount of dust pose a great threat to the health of operators. [0004] In order to so...

AI Technical Summary

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a kind of reinforced concrete separation device based on electromagnetic hot melting that overcomes multiple technical difficulties such as high noise and dust pollution during solid separation; In the high-frequency alternating magnetic field, eddy currents will be generated, so that the characteristics of rapid heating and temperature rise will melt the solid steel bars into a liquid state, so that in the case of zero noise and low pollution, combined with the principle of phase change (the steel bars change from solid to flowing. liquid state) realizes the separation of steel bars and concrete, effectively solving the problems of high energy consumption, noise, dust and pollution in traditional crushing and separation methods
