Say goodbye to “dirty, messy and poor” and talk about how concrete mixing plants can achieve energy conservation and environmental protection and practice the concept of ecological civilization

With the continuous development of society, the progress of infrastructure construction is constantly advancing, the popularity of concrete mixing stations is increasing year by year, and the mixing station equipment production industry has developed extremely rapidly in recent years. Since the 18th National Congress of the Communist Party of China proposed the construction of ecological civilization, the development of many industries has been restricted. After several generations of innovation and development of concrete mixing stations, "green mixing stations" will replace traditional forms and become the development direction of the industry. The key to building an environmentally friendly mixing station is to reduce and reasonably control the various industrial pollution generated during the production process. The key to building an energy-saving mixing station is to reduce the required human, material, electricity and other resources from the preparation to the daily operation process, and comprehensively improve the input-output ratio.

This article will combine the opinions of Jinhuiyuan Mechanical Engineers to start from the problems existing in traditional mixing plants in terms of environmental protection and energy saving, and propose corresponding improvement measures and maintenance precautions for different links.

Environmental protection measures for mixing stations

The traditional mixing station mainly produces "waste residue, waste liquid, dust, noise" and other forms of pollution during use. Different pollution in different parts requires different purification treatment methods.

1. Dust control measures for mixing stations: isolation and recycling. Environmentally friendly mixing stations should adopt "double insurance" measures for dust treatment. The first is isolation, that is, all dust pollution sources in the mixing station system are sealed and sealed to isolate the pollutants from the outside world; then specific measures are taken according to the different causes of dust generation, and finally the purpose of recycling and reuse is achieved.

2. Control measures for the "noise" of the mixing station: isolation and noise reduction. The noise of the mixing station mainly comes from: coarse aggregate transportation, high-power motor operation and air control system operation. The closed packaging of the mixing station to isolate dust mentioned above also plays a positive role in noise isolation. In addition, effective noise reduction measures should be adopted in key areas: (1) Wear-resistant rubber linings should be used instead of wear-resistant steel linings in aggregate weighing hoppers and aggregate pre-storage hoppers; (2) Adjust the order of coarse and fine aggregate feeding, first feeding some sand and then stones, which can effectively buffer the high-decibel noise caused by coarse aggregate directly hitting the steel plate; (3) Reasonably apply silencers in the air system to control and isolate the vibration and noise of the air compressor.

3. Control measures for "waste liquid and waste residue" in mixing stations: recycling. In the operation of mixing stations, waste liquid and waste residue will inevitably be generated. They come from the regular cleaning of mixing stations, mixing trucks and materials, and scrapped concrete. If they are recycled reasonably, it can not only achieve "zero emission", reduce the transportation and treatment costs of waste materials, but also turn waste into treasure to increase economic benefits.

Energy-saving measures for mixing stations

A mixing station requires considerable manpower and material resources from the beginning of preparation to normal operation, including the land area, the initial preparation cost including the construction period and construction volume, the hardware investment cost including the cost performance of the mixing station, energy-saving devices, supporting equipment, and the later operation cost, so its energy-saving issue must be considered comprehensively from all aspects.

1. Site selection and energy saving. The site selection for the station should be considered from two aspects: location and terrain. The location selection should focus on the supply area of ​​finished concrete and the convenience of material transportation. A suitable location can effectively reduce transportation costs. For the terrain, according to the structural characteristics of the mixing station, it is advisable to select unequal height planes. The higher plane is set as the back-end sand and gravel plant, and the lower plane is set as the front mixing main station. The aggregate batching system is set according to the boundary between the high and low planes to reduce the energy consumption generated by aggregate transportation through the terrain.

2. Station type selection and energy saving. There are many ways to classify mixing stations. Here, mixing stations are divided into fixed and mobile types according to the energy-saving effect. Mobile mixing stations basically have no foundation construction, can use temporary sites, and can change construction sites more frequently; one type of fixed mixing station, the "tank-top mixing station", can save about 20% of floor space compared to ordinary mixing stations, and effectively reduce the length and power of the screw conveyor.
