(Summary description)Brief introduction of positive pressure dense phase conveying system The positive pressure dense phase conveying system uses compressed air as the power source to transport materials. Forced pneumatic conveying is adopted, relying on a closed pressure vessel (transmitting tank) as the transmitter, the general air source pressure is 0.5 Mpa ~ 0.7 Mpa, and the operating pressure is 0.3 ~ 0.5 Mpa. Above 1000m. The way of conveying materials in the pipeline at lower speed, dune state, fluidization or agglomeration state is called positive pressure dense phase conveying. Applicable fields: food, chemical, rubber and plastic, lithium battery, new energy and other industries   Positive pressure dense phase conveying equipment High pressure air compressor or Roots blower, or positive pressure dense phase sending tank, etc. Positive pressure dense phase conveying method According to the conveying characteristics, the positive pressure dense phase conveying system can be divided into two modes: positive pressure dense phase dynamic pressure conveying and positive pressure dense phase embolization conveying. The way of conveying the material in the pipeline in a medium-low speed dune state or fluidization is called dense phase dynamic pressure conveying; the way of conveying the material in the pipeline in agglomeration state at a lower speed is called dense phase embolization conveying. The working principle of positive pressure dense phase conveying system Due to the action of pressure, the material enters the conveying pipe from the sending tank, and the compressed gas is opened and closed at a certain frequency through the solenoid valve to form a pulsed air flow (air knife). The static pressure difference is used as the driving force to push the material forward. After reaching the separation device for material and gas separation, the material falls into the silo, and the gas is discharged into the atmosphere to realize transportation.   Positive pressure dense phase conveying characteristics 1. Low flow rate but large conveying capacity, which has little effect on material quality; 2. The system has higher pressure and lower air consumption; 3. The control system is automated, and the requirements for various electrical components are high; 4. Multi-point feeding and multi-point unloading; 5. Due to the low material conveying speed, the degree of wear to the pipeline and material is low; 6. The sending tank (also known as the silo pump) is a pressure vessel, which is a mandatory equipment for signing; 7. The air source is generally a screw air compressor, and the post-processing equipment must be matched; 8.
