PLC Control System Dense Phase Pneumatic Conveying Injection Tank
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
wtih a pipeline. its flexible.
4. Pneumatic conveying system offer greatly reduced capital cost
for long distance conveying.
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.
Product Features
1. High conveying pressure, up to 0.5MPa, realizing long distance
(100-300m) powder conveying
2. Low flow rate, high solid gas ratio and low gas consumption
3. The material has high adaptability and versatility, and has
little impact on the quality of the material in the process, which
can meet the transportation of fragile and strong abrasive
materials.
4. One point to multi-point feeding can be realized
