Method for preparing aerated concrete aggregate by using construction waste

Abstract

The invention relates to a method for preparing aerated concrete aggregate by using construction waste. A workbench, a belt conveyor, a shearing device and a crushing device are included; the upper end of the workbench is fixedly provided with the belt conveyor; the upper side of the workbench is fixedly provided with the shearing device; the lower end of the shearing device is fixedly provided with the crushing device; and the shearing device comprises a rectangular table cylinder, a first motor, a chain wheel, a toothed chain belt, a first gear, a second gear, a third gear, a first shearing frame, a second shearing frame and a third shearing frame. According to the method, the shearing device is matched with the crushing device, construction waste fragments are completely processed until all particles are uniform in size; and during processing, the construction waste fragments can be continuously fed, and the belt conveyor does not need to be turned off, so that the processing quality is improved.

Description

technical field [0001] The invention relates to the field of building material processing, in particular to a method for making aerated concrete aggregate by using construction waste. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals, and Due to the development of society, old buildings need to be demolished. The demolished construction waste can be crushed and used as the aggregate of air-entrained concrete. Air-entrained concrete is mainly composed of siliceous and calcareous materials. Raw materials, mixed with air-generating agent, light porous silicate products made through batching, stirring, pouring, pre-curing, cutting, autoclaving, curing and other processes. Concrete aggregate refers to the skeleton or filling in concrete Functional granular l...

AI Technical Summary

Problems solved by technology

[0004] (1) In the process of processing construction waste by traditional processing equipment, it is easy to cause incomplete processing of construction waste fragments, which leads to uneven particle size of concrete aggregate and affects the quality of aerated concrete

[0005] (2) In the process of processing construction waste, traditional processing equipment needs to frequently close the transport parts, which can easily lead to a reduction in the service life of the equipment and affect the processing efficiency
