Changzhou Chang Heng Deyu Powder Integrative Systems Ltd, the main pneumatic conveying systems, weighing packaging equipment, dosing delivery system Introduction ② longitudinal vortex flow. It is within the cyclone, forming a single side of the circulating vortex flow over the entire length of the outer cyclone center interface device, so that the exhaust pipe near the end of the radial velocity airflow increase, resulting in the force exceeds the particles suffered centrifugal force, causing a short circuit, affecting the separation efficiency. Changzhou Chang Heng Deyu Powder Integrative Systems Ltd, the main pneumatic conveying systems, weighing and packaging equipment, transportation systems Introduction ingredient works in the feed during the instant tea powder dense phase conveying equipment, material or by double butterfly inflatable butterfly is transmitted into the vessel, the replacement of the air through the exhaust valve to release out, making it easier to feed instant tea powder dense phase conveying equipment, but also impede the flow of material to eliminate the back pressure. When sending the tank is full (by level meter display, up to 90% of the tank volume) feed valve and the exhaust valve is closed and sealed at the same time, followed by the addition of compressed air to the top of the tank through the intake valve is sent, the added compression the air is mixed with the material when the pressure tank reaches the set value will automatically open the bottom outlet valve, then the entire transfer line pressure Pianxiang instant tea powder dense phase conveying, then the plunger-like material in the form of delivery, until Material emptying. When sending the tank pressure falls to zero pneumatic supply namely closed, while a small amount of remaining gas is discharged also sent tanks and pipelines. Features of the system is at the beginning and end of the transfer process has a high gas flow and a higher delivery pressure, sometimes "call" at the end of the transport process indicates. Advantages simple system piping, suitable for short distances, good mobility materials. Disadvantage large gas consumption, equipment and material wear large, large displacement.
