Environmental protection for Concrete Mixing Plant

  Environmental protection is a great concern in economic development. In the acceptance of the concrete mixing plant must check each environmental protection content, but also the construction of civilized mixing plant, green concrete production of this requirement, in our acceptance of the mixing plant environmental protection standards are mainly effective control of dust, waste water, noise, solid waste. Thus realizing the real concrete green production.

       Dust control.

　　In the concrete mixing plant, the main places where dust is easily generated are the mixing building feeding entrance and the material field and the price tank. In order to eliminate dust spillage, the mixing plant is selected to be a closed mixing plant. In order to further eliminate the dust in the production, additional movable colored steel plates are installed as dust surfaces and the space of the closed dust vent is used to control the dust generated in the closed space. Two external symmetrical water mist jet pipes are added at the cement feeding port for dust suppression to stop dust spreading from the source. The main thing is to add sprinklers at the top of the material yard, which can be manually or automatically controlled to suppress dust when the material yard is dusty, and an automatic high-pressure water curtain can be added at the entrance of the material yard. To eliminate dust spillage.

　　Waste water treatment.

　　A drainage ditch is set up in the concrete mixing plant, and a three-stage sedimentation tank is set up at the end of the ditch, and a solid-liquid separation device and a filter-pressing device are equipped to separate the waste materials from the well sewage for reuse. The precipitated water will be recycled, so that the wastewater in the whole production area can be recycled after all the treatment, i.e. to meet the environmental emission standard. Realize zero discharge of sewage.

　　Noise control.

　　The noise in the concrete mixing plant mainly comes from the main mixing equipment and the air compressor and the vehicles in the plant. The noise of the equipment itself can be installed in the closed concrete structure and maintenance and overhaul can be strengthened during the use, which can prolong the service life of the equipment and reduce the noise pollution. For the noise generated by vehicles, if the station is built in a residential area, it is necessary to set up compartment walls and compartment belts according to the actual situation.

　　Solid waste disposal.

　　The solid wastes in concrete mixing plant are mainly solid wastes from cleaning and sand separation and domestic wastes. Garbage ponds are built in the plant and are managed and handled in a unified manner. The waste generated from production can be proportioned to concrete production according to the actual situation, and domestic waste should be uniformly removed by municipal garbage trucks and uniformly disposed of.
