Concrete mixer project construction has played a significant role. It can also be applied to many other constructions. Therefore, it must adapt to the needs of the terrain conditions, according to the different requirements of the design of the machine and its components, which is very important machine technology functions are: modify, add and expand, the automation system should have a high degree of flexibility.
1. Mixer
Control system to ensure safe and reliable task is to provoke the operation, which is mainly motor and mixer closed-loop control mechanism, covering the mixing tank indirect drive control is also necessary. Today, most mixers are consistent, and in addition, the measuring device used to measure humidity in the system is equipped with a microwave sensor and a temperature sensor
2. Concrete management
Concrete management equipment, including concrete silos, concrete metering, said components controlled by the inverter spiral. A metering or radar sensor used to measure the material of a silo. In order to avoid a lot of dust, concrete mixer, must also be equipped with air filters, vibration principle, the use of dust in the air automatically deleted. In addition, the use of sensors can also protect the silo, to avoid excessive pressure on the warehouse.
3. Transport sand
In the unloading of sand or by the strain sensor in the conveyor belt sliding. If you are using gravel cars, they are controlled by the inverter, terminal position sensor and safety terminal position sensor. The sand bin consists of one to two vibrators that ensure accurate packaging material. In demanding applications, silos are measured by radar sensors. If necessary, you can also use the radar sensor to measure the moisture in the sand. Therefore, the concrete mixing process obtained in the measurement data collection.
4. Measure the amount of water
First with two control valves weighing by weighing, and then use a parallel flow meter more accurate measurement.
5. Add the accessories
Concrete is produced according to the specific requirements of different applications, so its characteristics are not the same. Today, it is hard to imagine that no ingredients are added to the concrete production process. These auxiliary materials are mainly supplemented by pumps and metering. The following are the same as the.
