Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a dust reduction device for a commercial concrete material field. Background Art

[0002] Commercial concrete has been widely used in the construction industry in recent years. Its preparation overcomes the dust and noise pollution caused by traditional on-site mixing. In particular, some large-scale mixing plant manufacturers with high technological content tend to pay more attention to environmental protection issues. However, a large amount of dust will be generated in the material yard of a large mixing plant, and the spread of dust will cause environmental pollution.

[0003] Prior art publication number: CN212017192U, provides a technical solution: a dust reduction spray system for a mixing station, which includes a water reservoir located on one side of a storage yard, a water pipe is provided at the water reservoir, a water supply branch is set up on the top of the storage yard, the end of the water supply pipe away from the water reservoir is connected to the water supply branch, a number of nozzles are opened on the water supply branch, a pressure pump is provided on the water pipe, a connecting pipe is provided at the water reservoir, a number of atomizing pumps are neatly arranged in the storage yard, the end of the connecting pipe away from the water reservoir is connected to the atomizing pump, a nozzle is provided on the atomizing pump, a fixing frame is provided on one side of the nozzle, and the pressure pump and the atomizing pump are electrically connected to a control switch. The dust reduction spray system for a mixing station of the utility model controls the operation of the pressure pump and the atomizing pump through the control switch, combines the dust reduction by spraying water from the nozzle with the dust reduction by atomizing water from the atomizing pump, which is not only convenient for controlling the amount of water sprayed, but also saves water, and does not need to filter the water in the water reservoir in advance, which is convenient for users to use.

[0004] but:

[0005] The booster pump and the atomizing pump are started alternately and regularly by a control switch. When the booster pump is turned on, the water in the water reservoir is sprayed in the storage yard through the water pipe, the water branch and the nozzle in turn to spray and reduce dust. When the atomizing pump is turned on, the water in the water reservoir is pumped out and atomized by the atomizing pump through the connecting pipe, and then sprayed into the storage yard through the nozzle to reduce dust. However, the spraying method using water mist is not easy to control the direction of its dispersion due to its lightness, and it will directly affect the humidity in the storage yard, which is not conducive to the storage of concrete. Although the spraying method of water mist saves some water resources, the scattered water mist will still cause waste. Utility Model Content
