Dust falling device for civil engineering

Abstract

The invention relates to the field of civil engineering, in particular to a dust falling device for civil engineering. The invention aims at providing the dust falling device for civil engineering. According to the technical scheme, the dust falling device for civil engineering comprises an underframe, an extrusion assembly, a grinding assembly, a separation assembly and a control screen, wherein the underframe is connected with the extrusion assembly; the underframe is connected with the grinding assembly; the underframe is connected with the separation assembly; the underframe is connected with the control screen; the extrusion assembly is connected with the grinding assembly; and the extrusion assembly is connected with the separation assembly. When the device is used, a mixture in a gypsum board is automatically pressed into small blocks, then surface paper on two sides of the gypsum board is straightened and expanded, meanwhile, the small blocks of the mixture in the gypsum board are pulled back and forth to quickly fall off from the lower portion of the gypsum board, thus dust is effectively prevented from being dispersed into air, and in addition, glass fibers in the small blocks of the mixture are automatically separated, so that resource reutilization is facilitated.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a dust suppression device for civil engineering. Background technique [0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction. That is, various engineering facilities built on the ground or underground, on land, directly or indirectly serving human life, production, military affairs, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, Airports, offshore platforms, water supply and drainage, and protection projects, etc. Civil engineering refers to various technical work such as survey, planning, design, construction, installation and maintenan...

Problems solved by technology

[0005] In order to overcome the existing technology, one of the paper-faced gypsum boards is a lightweight board made of gypsum slurry as a sandwich and paper on both sides as a protective surface. When demolishing or renovating old buildings, it will be disassembled. A large number of gypsum boards. When the existing equipment recycles this type of gypsum board, the face paper on both sides of the gypsum board is torn off first, and then the gypsum slurry is crushed. The gypsum board face paper is relatively wide and has high toughness, resulting in During the process of tearing off the face paper, relatively large dust will be raised, polluting the environment and endangering the health of workers. In addition, a large amount of glass fibers are doped in the gypsum slurry to increase the structural strength of the gypsum board. The existing device does not separate glass fibers function, which greatly increases the difficulty of purification in the subsequent production of recycled materials, and the technical problem to be solved: provide a dust suppression device for civil engineering
