JuhengPositive pressure dense phase conveying systemIt is an equipment for conveying powder, granular, and block materials. It uses air as the conveying medium and relies mainly on compressed air as the conveying medium for rapid gas flow. The sending tank can only be transported intermittently,The conveying distance can reach over 1500 meters. Due to the high solid to gas ratio of the transported material, the velocity of the material in the pipeline is relatively low, exhibiting wave like, agglomerated, or fluidized conveying. Therefore, this conveying method has the characteristics of high efficiency and good conveying quality. The positive pressure dense phase pneumatic conveying system has high conveying efficiency and can be adapted to local conditions. The average power consumption per ton of conveying is 1.5KW, which is approximately 60% of other conveying systems.

1. Feeding stage

   At the same time as the valve for feeding is opened, the valve for discharging is immediately opened. Due to the influence of gravity, the material falls into the bin pump. When the material is full, a signal is generated through induction, and then the exhaust valve and feeding valve are automatically closed to complete the automatic feeding process;

2. Fluidization and pressurization stage

   After opening the intake valve, compressed air enters the bottom of the chamber pump. While the chamber pump is pressurized at the top, the air at the bottom diffuses and becomes fluidized. At this point, air pressure has also been established inside the chamber pump.

3. Transport status

   When the pressure inside the pump reaches a certain value, the pressure gauge or pressure switch sends a signal, and the discharge valve automatically opens. The fluidization of the material on the fluidized bed is strengthened, and transportation begins. The material inside the pump gradually decreases, and at this time, the material on the fluidized bed is always in a state of fluidization and transportation;

4. Purging stage

   After the material transportation in the warehouse pump is completed, the pressure also decreases. A signal is sent through the sensor pressure switch or pressure gauge, and the ventilation continues for a certain period of time. Compressed air is used to clean the pipeline, and then the inlet valve is closed. After a period of time, the discharge valve is closed and the inlet valve is opened to complete the transportation cycle. The flow rate is low and the wear on the pipeline is small; Low gas consumption, suitable for long-distance transportation; Single tank conveying is intermittent conveying, achieving continuous conveying requires the use of double tanks; Less breakage and low noise; The degree of automation is relatively high.

   Our current positive pressure dense phase pneumatic conveying system's pneumatic conveying pump is based on the advanced technology and structure of similar products at home and abroad. When conveying granular materials such as fly ash, casting sand cement, grain, mineral powder, battery raw materials, etc., the conveying pipeline can be arranged according to the specific terrain to achieve centralized, decentralized, high height and long-distance conveying. The conveying process is not limited by conditions and can ensure that the materials are not damp. With the use of production and environmental protection, this equipment is equipped with an automated operation platform, which can achieve manual and automatic control. The automatic control adopts two forms: relay or PLC microprocessor. Through long-term operation, practice has proved that its performance is stable, the quality is reliable, and there is no dust pollution. It is an ideal pneumatic conveying. Equipment.
