environment protection is a matter of great concern in current economic development. When the concrete batching plant is completed and accepted, every environmental protection must be inspected. It is also the basic requirement for the construction of a civilized mixing plant and green concrete production. In our acceptance, the environmental standards for the mixing plant are to effectively control the dust, waste water, and noise. Things. In order to achieve real concrete green production.

(1) Dust control:

The places where dust is easily generated in the concrete mixing plant are mainly the mixing hatch inlet, feed yard, and powder tank. The mixing tower of the equipment selected to prevent dust spillage is closed and agitated. In order to further eliminate dust during production, an additional color steel plate is used as a dust surface, and a closed dust outlet space is used to control the generation of dust in an enclosed space. Two external symmetrical spray nozzles were added to the cement feed port to suppress dust and prevent dust from spreading from the source. In the material yard, sprinkler devices are mainly installed at the top. When the dust in the material yard is large, the spray pressing dust can be manually or automatically controlled. The material field mouth can also be equipped with an automatic high-pressure water curtain. Prevent dust spills.

(2) Waste water treatment:

Drainage ditch is set in the station of the concrete mixing plant, and a three-stage sedimentation tank is set at the end of the drainage ditch. The solid-liquid separation device and the pressure filtration device are equipped, and the waste in the well sewage is separated for reuse. The recycled water is recycled so that the wastewater from the entire production area can be reused after being treated in full, that is, it reaches the environmental discharge standard. Realize zero discharge of sewage.

(3) Noise Control:

The noise in the concrete mixing plant mainly comes from the mixing host equipment and the air compressor and the vehicles in the station. The noise of the equipment itself can be installed in a closed concrete structure. During the use of the equipment, the maintenance and repair are strengthened, that is, the service life of the equipment is prolonged, and the noise pollution can be reduced. In view of the noise generated by vehicles, if a station is set up in a residential area, partition walls and compartments may be provided according to the
