A crushing device with screening function for crushing construction waste

Abstract

The invention discloses a crushing device with a screening function used for construction waste crushing. The device comprises a centralized drying device, wherein two sides of the centralized dryingdevice are both provided with water receiving devices, the centralized drying device comprises a centralized feeding bucket, the bottom end of the centralized feeding bucket is connected with a screening device through a diffusion hopper, two sides of the screening device are both connected with material discharging mechanisms used for discharging residual materials, the inner portion of each material discharging mechanism is provided with a combined crushing mechanism used for crushing large materials, the bottom end of the screening device is provided with a rolling grinding mechanism used for crushing small materials, and the bottom ends of the material discharging mechanisms and rolling grinding mechanism are all connected with material guiding buckets, the material guiding buckets ofthe material discharging mechanisms are connected with the rolling grinding mechanism through material transportation seats, the screening is carried out on waste materials through the screening device, and crushing processes are carried out stepwise through different devices, so that the crushing of the waste materials is more thorough and even, and overheating cannot appear easily during the crushing processes.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a crushing device with screening function for crushing construction waste. Background technique [0002] Construction waste refers to construction waste, which 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. Waste, construction waste refers to the general designation of muck, waste concrete, waste masonry and other waste produced by people in the production activities of the construction industry such as demolition, construction, decoration, repair, etc., and is classified according to the source of generation. Construction waste, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into waste soil, concrete blocks, c...

AI Technical Summary

Problems solved by technology

[0005] (1) The general crushing device directly crushes construction waste of different specifications, which not only prolongs the crushing time, but also easily causes incomplete crushing of waste, resulting in the failure of smooth reuse of construction waste;

[0006] (2) When crushing construction waste, since the construction waste carries a certain amount of water, if it is not processed in time and crushed directly, it will cause the waste to stick to the inner wall of the device, which is difficult to clean and will corrode the device for a long time effect;

[0007] (3) And when crushing, due to the high mechanical strength, construction waste will generate a lot of heat, and long-term work will inevitably lead to temperature rise, which will easily lead to damage inside the device
