How to do the environmental protection of concrete mixing station?

The noise of concrete mixing station is mainly the noise of main mixer, the running noise of concrete tank car, the noise of belt conveyor and the noise of tank car transporting cement. If there are no buildings or green belts, these noises will seriously affect our daily life, so it is necessary to solve the problem of noise pollution.

There can be more green belts and more buildings next to the concrete mixing station to prevent the spread of noise and make it gradually weaken.

Second, wastewater pollution.

A mixing station needs many steps when producing concrete, such as cement and sand. These raw materials are usually directly exposed. In case of rainstorm, a large amount of rainwater will impact the ground and produce wastewater containing cement and fine sand. If these wastewater cannot be treated in time, it will pollute the nearby water sources and the living environment of people around.

In fact, a wastewater collection pool can be built in the concrete mixing station, which can be used for production after precipitation treatment, which not only saves resources, but also protects the environment.

Third, dust pollution.

The concrete mixing station will cause dust pollution when producing concrete, mainly the dust caused by sand truck and natural stacking wind; There are also various kinds of dust generated by pumping cement, fly ash, mineral powder, dry powder additives or powder unloading in the tank.

Weighing various powders, stirring, and a large amount of dust mixture is produced in the process of stirring. Because dust pollution to the environment is the most intuitive, sealing treatment and automatic car washing machine can be used in concrete production to prevent dust from being taken out of the factory.

Extended data:

The inspection items before the operation of concrete mixing station shall meet the following requirements:

(1) The transmission and moving parts, warehouse doors, bucket doors, rails and all supporting mechanisms of the mixing drum are free from foreign bodies;

(2) The oil level of each lubricating oil tank meets the requirements;

(3) Open the valve to discharge the excessive accumulated water in the gas-water separator in the gas path system, and open the drain plug of the gas storage tank to discharge the oil-water mixture;

(4) The wire rope installation and drum winding of the lifting bucket or shovel are correct, the wire rope and pulley conform to the regulations, and the braking of the lifting bucket and shovel is sensitive and effective;

(5) The bolts of each part have been tightened, the import and export valves are free from over-limit wear, the tension of each conveyor belt is appropriate and there is no deviation;

(6) All control and display parts of the weighing device work normally, and its accuracy meets the requirements;

(7) All electrical devices can effectively control mechanical actions, and all contacts and dynamic and static contacts have no obvious damage.
