Magnetic sorting tool for construction waste

Abstract

The invention provides a magnetic sorting tool for construction waste and belongs to the technical field of construction waste sorting. The sorting tool comprises a shell, a discharging port and an impurity discharging port, further comprises a buffer bin and a magnetic sorting roller, wherein the discharging port and the impurity discharging port are formed in the shell, an end of the buffer binis connected with the magnetic sorting roller, the magnetic sorting roller comprises a fixed magnetic area and a non-magnetic area, a surface, closest to the magnetic area, of the magnetic sorting roller is an absorption surface, and the absorption surface is close to the end of the sliding way. The sorting tool is advantaged in that the falling speed and impact energy of the construction waste are reduced through a buffer assembly, impact damage of the construction waste to the magnetic sorting roller is relieved, the service life of the magnetic sorting roller is prolonged, moreover, the magnetic sorting roller has the sufficient time to absorb magnetic impurities, absorption efficiency is improved, and the sorting effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of construction waste sorting, in particular to a magnetic separation tool for construction waste. Background technique [0002] With the continuous acceleration of the urbanization process, the generation and discharge of construction waste in the city is also increasing rapidly. According to rough statistics, during the construction process of every 10,000 square meters of buildings, only 500-600 tons of construction waste will be generated. According to this calculation, the amount of construction waste generated and discharged by construction alone in China exceeds 100 million tons every year, and the amount of construction waste generated by building decoration, demolition, and building materials industry will reach billions of tons. Therefore, the effective recycling of construction waste has been paid more and more attention by the government and society. Using crushing, grinding, screening and other...

Chinese Patent No. CN201520143012.X discloses a slag iron removal device, which removes iron through the adsorption of arc-shaped magnets in the drum, but construction waste is often a large piece of raw material, which directly impacts the drum, causing great damage to the drum and the arc-shaped magnets , shorten the service life; and, the falling speed of the raw material is fast, and the contact time with the drum is short, some iron impurities will not be absorbed in time, and will be mixed into the pure slag, and the iron removal efficiency is low; secondly, during the rotation of the drum with convex teeth, it will Bring part of the slag to the iron impurity outlet, resulting in waste of raw materials and incomplete separation of materials
