Construction waste crushing and reusing device with iron recovery function

Abstract

The invention discloses a construction waste crushing and reusing device with an iron recovery function. The construction waste crushing and reusing device comprises a base. A working box is fixedly arranged on the top of the base through a bracket. A left second rotary shaft and a right second rotary shaft are arranged on the top in the working box. Second crushing rollers which are matched witheach other are correspondingly and fixedly mounted in the middle parts of the left second rotary shaft and the right second rotary shaft. Gears which are engaged with each other are correspondingly mounted on the left second rotary shaft and the right second rotary shaft. A gear motor is fixedly arranged on the rear side wall of the working box. A motor shaft at the front end of the gear motor isconnected with the rear end of the second rotary shaft on the right side. An opening is formed in the right side wall of the working box. A receiving tank is hinged to the opening position through a hinge. The receiving tank is located below a first crushing roller. The receiving tank is inclined to the lower left corner. An electromagnet is fixedly arranged at the bottom of the receiving tank andlocated in the working box. According to the construction waste crushing and reusing device with the iron recovery function, iron is attracted by the electromagnet at the bottom of the receiving tankand accordingly recovered; and when the receiving tank is inclined to the lower right corner, the electromagnet is de-energized, and the iron can slide into the iron recovery box.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a construction waste crushing and recycling device with an iron recovery function. Background technique [0002] With the improvement of urbanization and the continuous transformation of old urban areas, old buildings are demolished almost every day, and most of the construction waste is transported to the suburbs or villages without any treatment, and is piled up or landfilled in the open air. It not only consumes a large amount of land and construction costs such as land acquisition, but also causes a huge waste of resources. If these construction wastes can be reused, it will not only avoid the high cost of handling, save money, but also can be remade into concrete for on-site reuse. [0003] The construction waste crushed by the general construction waste crushing device is not screened, and the crushing effect is difficult to meet the requirements. Moreover, ...

AI Technical Summary

Problems solved by technology

[0003] The construction waste crushed by the general construction waste crushing device is not screened, and the crushing effect is difficult to meet the requirements. Moreover, the construction waste often contains steel bars, iron nails, etc., and its value is relatively high. If the iron materials are not recycled separately, it will not only cause resources. waste and also adversely affect the reuse of other construction waste
