The positive pressure dense phase pneumatic conveying system is mainly composed of a feeding device, a sending warehouse pump, pipelines, valves, a bottom dust removal device, a bottom gasification device, a bottom discharge device, a power source, a program control device, etc. The structure is fully automatic  PLC intelligent control, manual switching is also possible, easy to operate and maintain.
 The positive pressure dense phase pneumatic conveying system is one of the commonly used conveying equipment for conveying granular, powdery, and massive materials. It mainly uses compressed air as the conveying medium, adopts forced pneumatic conveying, and relies on a closed pressure vessel as a transmitter.  The source pressure is 0.5Mpa-0.7Mpa, and the operating pressure is 0.3Mpa-0.5Mpa. The sending tank can only adopt intermittent conveying mode, and the conveying distance can reach more than 1000 meters.  The material is transported in the pipeline at a low speed, in a dune state, fluidized or agglomerated state, with high transport efficiency and good transport quality.  Transportation energy consumption is much lower than its form of pneumatic conveying system. The energy consumption per ton of conveying volume is 1.5kw per 100 meters, which is about 65% of other forms of pneumatic conveying system.
 1. Feeding stage
 The feed valve and exhaust valve are opened, and the material falls freely into the pump body. When the material is full, the level indicator sends a signal, and the feed valve and exhaust valve are automatically closed to complete the feeding process;
 2. Fluidized pressurization stage
 Open the intake valve, the compressed air enters the upper and bottom of the pump body, the upper part is pressurized, and the lower air diffuses and passes through the fluidized bed, so that the material is in a fluidized state, and the pressure inside the pump rises;
 3. Delivery status
 When the pressure in the pump reaches a certain value, the pressure gauge or pressure switch sends out a signal, the discharge valve opens automatically, the fluidization of the material on the fluidized bed is strengthened, and the conveying starts, the material in the pump gradually decreases, and the material on the fluidized bed at this time  Always in the state of fluidizing and conveying;
 4. Purge phase
 When the material in the pump is delivered and the pressure drops to the resistance of the pipeline, the pressure gauge or pressure switch will send out a signal, the ventilation will continue for a certain period of time, the compressed air will sweep the pipeline, and then the intake valve will be closed. After a period of time, the discharge valve is closed and the feed is opened  Valve, complete a conveying cycle.
 System Features
 The positive-pressure dense-phase pneumatic conveying system is a dense-phase high-pressure pneumatic conveying system that uses an air compressor as the gas source and a warehouse pump to convey materials.  The positive pressure dense phase pneumatic conveying system has the advantages of low flow velocity, small air consumption, suitable for long-distance, large-capacity conveying, easy to realize fluidized conveying, low noise and less broken, suitable for conveying cement, fly ash, and mineral powder  , Foundry sand, chemical raw materials and other materials with high abrasiveness.
 1. Flexible configuration of conveying pipeline makes the production process of the factory more reasonable;
 2. The conveying system is completely airtight, with less dust, which can meet environmental protection requirements;
 3. Few moving parts, convenient maintenance and easy automation;
 4. The material transportation efficiency is high, which reduces the packaging and loading and unloading transportation costs;
 5. It can prevent the conveyed materials from being damp, stained and mixed with other sundries, ensuring the conveying quality;
 6. A variety of technological operations can be realized at the same time during the transportation process;
 7. For materials with unstable chemical substances, inert gas can be used for transportation.
 8. The flow rate is low, and the abrasion to the pipeline is small; the air consumption is small, suitable for long-distance transportation; the single tank transportation is intermittent transportation, and continuous transportation must be used in double tanks; less broken, low noise; high degree of automation.
 The pneumatic conveying pump of our current positive pressure dense phase pneumatic conveying system is based on the advanced technology and structure of similar products at home and abroad, and adopts positive pressure pneumatic conveying to convey powder and granular materials. It is used in power plant fly ash, cement, and casting.  For the transportation of powder and granular materials such as sand, mineral powder, grain, chemical raw materials, etc., the transportation pipeline can be arranged according to the specific terrain to achieve centralized, dispersed, large height and long-distance transportation. The transportation process is not restricted by conditions and can ensure that the materials are not wet and used.  For production and environmental protection, this equipment is equipped with an automatic operation console, which can realize manual and automatic control. The automatic control adopts two forms of relay or PLC microprocessor. Through long-term operation, practice has proved that its performance is stable, reliable in quality, and free of dust pollution.  It is an ideal pneumatic conveying equipment.
