Pneumatic Vacuum Grain Conveyor Dense Phase Pneumatic Tube Conveying System

Pneumatic vacuum grain conveyor Dense Phase Pneumatic Tube Conveying System

Dense-phase pneumatic conveying system is specially applied to a variety of dust long-distance sealed transport; the adaptive conveying distance equivalent is 50-500 meters, transport materials: fly ash, lime powder, cement, aluminum powder, mineral powder, saw dust, straw and so on. The equipment is simple, with small occupation area, it can make full use of space, and pipelines can be flexible layout, so that the configuration of the plant equipment will be more rational. System configuration is complete, PLC set control the entire system, fully automated operation, easy maintenance.

1. Pneumatic conveying system are relatively economical to install and operate
2. Pneumatic conveying system are totally enclosed and if required can operate entirely without moving parts coming into contact
with the conveyed material. Being enclosed there are hygiene & cleanlinesss benefits
3. A pneumatic conveying system can convey a product to any place with tubes. its flexible.
4. Pneumatic conveying system offer greatly reduced capital cost for long distance conveying.
5. PLC full automation
6. Pneumatic Conveying System are much better suitable to powder handling than mechanical conveyor because the conveyance channels
used in pneumatic conveyors are completely enclosed.
7.Pneumatic conveyors can be designed to move products between floor levels and around difficult angles.
8. The whole system is composed of compressed air source, pneumatic vessel, control cabinet,conveying pipe and ash storage.

Working Principle

In the feeding process, the material is fed into the sending tank through the double butterfly valve or expansion butterfly valve, and the replaced air is released through the exhaust valve, which makes feeding easier and eliminates the reverse pressure that hinders the flow of materials. When the sending tank is full (up to 90% of the tank volume indicated by the level meter), the feed valve and exhaust valve are closed and sealed at the same time. Then, compressed air is added to the top of the sending tank through the inlet valve, and the added compressed air is mixed with the materials. When the pressure in the tank reaches the set value, the bottom discharge valve will be opened automatically, and then the whole conveying pipeline will be pressurized The material is transported in the form of plunger until the material is emptied. When the pressure in the sending tank drops to zero, the pneumatic supply is closed, and a small amount of residual gas is discharged from the sending tank and the transmission pipeline.
