Delivery tank basic delivery mode
This method is the least expensive, In batch feeding system.
It is generally suitable for shorter transmission lines and granular, liquid, abrasive and non abrasive materials. Such as quartz sand, plastic particles and so on.
It consists of a pressure vessel (a canister), an electric control system and a transmission line.
In the process of feeding, the material through the bell valve, butterfly valve or double expansion type butterfly valve was added to the sending tank, the replacement of the air out through the exhaust valve, the easier to feed, but also eliminates the reverse pressure barrier material flow.When the tank is full when sending (through leveldetector or weighing equipment to display, tank volume 80%) inlet valve and the exhaust valve is closed and sealed, and then compressed air into the tank top is sent through the air inlet valve, with compressed air and material mixing, when the tank pressure reaches the set value will automatically open the bottom discharge valve, then the pipeline pressure, then the material to form the plunger until the material conveying, emptying. When the pressure in the tank is lowered to zero, the pneumatic supply is closed and a small amount of remaining gas is expelled from the delivery tank and the delivery line.
The system is characterized by high gas flow and higher delivery pressure at the beginning and end of the conveying process, and sometimes "hu" to indicate the end of the delivery process
