Sometimes we live in a place around the sound of construction, especially when the sound of concrete mixer work is obvious, the noise is very big, so how does the high noise of concrete mixer work? Is there any way to deal with it?
It is important to fundamentally solve the noise pollution of concrete, but to solve the problem, we need to know the root cause of the problem! We all know that concrete mixing station is concrete mixing production place, concrete is made of sand, stone, cement and water through concrete mixer mixing and become a very important building raw materials.
The main noise sources in the operation of concrete mixing station are as follows: forklift shovel, feeding, vehicle noise; Air pump gas path and exhaust noise; Batching machine unloading and transporting transferred parts; In the process of mixing, the sand and stone materials collide with the mixing arm and reamer, resulting in a large noise. Unloading hopper and tanker in the finished product unloading process of interference and noise.
The cause of noise generated by concrete mixing plants has been identified and this noise pollution can be treated:
First, all the sand yards are sealed with sandwich panels to absorb noise. For air pump, air storage tank and other independent air equipment of concrete house, it is recommended to choose hollow brick concrete method, hydraulic cylinder selection of water cylinder; Batching machine and belt conveyor are all packed, and part of the transfer, dust removal and noise reduction equipment is installed; The mixer is equipped with baffle.
Host brand adopts high precision large brand mixer. The gap between the lining of the tank and the stirring blade can be up to 0.5mm to avoid the squeak of easy scraping stones when the gap is too large, and the special drilling machine is used to lift the two stirring shafts. Parallelism improves the stability of the transmission system and reduces the noise; Change discharge hopper, choose chute discharge, or improve the outlet toughness wear-resistant steel.
