Crusher for recycling construction waste

Abstract

The invention belongs to the field of construction waste treatment, and particularly relates to a crusher for recycling construction waste. The crusher for recycling the construction waste comprises a machine body; a material storage chamber is fixedly installed at the bottom of the machine body, the top of the material storage chamber is rotationally connected with a belt wheel, the belt wheel is located on the outer surface of the machine body, a feeding port is fixedly installed on the upper surface of the machine body, and a coarse discharging port is formed in the bottom of the feeding port. According to the crusher for recycling the construction waste, a baffle is arranged, when an auxiliary crushing wheel extrudes the baffle, a hydraulic telescopic rod shrinks, due to the fact that the stress on the two sides of the baffle is not uniform, the baffle swings left and right, the amount of waste entering each time is close, the probability of blockage and mechanism overload is reduced, the service life is prolonged, meanwhile, by means of extrusion of coarse materials and the crushing wheels and mutual collision between fine materials, noise generated during crushing is reduced, and the problems that a traditional crusher is large in noise and large in dust amount during working are solved.

Description

technical field [0001] The invention belongs to the field of construction waste treatment, in particular to a crusher used for recycling construction waste. Background technique [0002] Construction waste refers to the solid waste generated when a building is newly built, rebuilt, expanded or demolished. The long-term accumulation of construction waste not only occupies land, but also causes serious pollution to the environment, surface water and groundwater. In addition, it will directly or indirectly affect air quality. Therefore, if the construction waste cannot be recycled and reused well, it will have a great negative impact on our living environment. [0003] In addition to landfilling and stacking, the traditional method is to crush construction waste with a crusher. While reducing the footprint, the scrap can also be used as raw materials for unburned bricks, making full use of it and avoiding waste.

Problems solved by technology

The long-term accumulation of construction waste not only occupies land, but also causes serious pollution to the environment, surface water and groundwater. In addition, it will directly or indirectly affect air quality.

Therefore, if the construction waste cannot be recycled and reused well, it will have a great negative impact on our living environment.

[0003] In addition to landfilling and stacking, the traditional method is to crush construction waste with a crusher. While reducing the footprint, the scrap can also be used as raw materials for unburned bricks, making full use of it and avoiding waste. However, the general Most crushers adopt the method of single-stage roller crushing, and only use a single crushing wheel to work. This method results in a single crushing force during work, easy blockage inside, low crushing efficiency, and a large disparity in the volume of processed crushed materials, which is not conducive to unburned bricks. At the same time, when the crusher is working, it will generate very loud noise and dust due to the impact of large volume of crushed materials on the machine body.
