[0002] Concrete is a general term for engineering composite materials that are made by bonding aggregates into a whole with cementitious materials. Compared with traditional concrete, commercially produced and canned concrete is shipped on a large scale and poured using a pumping process. This not only improves production efficiency, significantly speeds up construction progress, and significantly shortens the construction period.

[0003] In the process of preparing concrete, the raw materials need to be stored in a storage bin. When the concrete raw materials are stored in the storage bin, the materials often fly, so that the space in the bin is filled with material dust, which is easy to have an adverse effect on the health of the workers. In the prior art solution, a dust reduction component is arranged at the top of the concrete raw material storage bin, and the dust reduction component includes a water supply pipe fixed on the top of the concrete raw material storage bin and connected to a water source, a water pump connected to the water supply pipe and used for pumping water, a spray pipe arranged in the concrete raw material storage bin and connected to the water supply pipe, and a plurality of atomizing nozzles arranged on the spray pipe. This application is conducive to improving the problem of dust diffusion in the storage bin affecting the health of the workers, but the solution also has a great disadvantage, that is, the waste of water resources is relatively serious, does not meet environmental protection standards, and there is room for further optimization.
