Description
How does pneumatic conveyor work?
Dense phase storage pump pneumatic conveying system
Operating principle of positive pressure dense phase pneumatic
conveying
The dense phase conveying pump is a relatively reliable dense phase
dynamic pneumatic conveying equipment that transports powdered
materials under high pressure (below about 1000kPa). There are two
unloading methods for dense phase pumps, with bottom discharge
being a commonly used method. The materials in the tank are
fluidized through a conical inflatable tank, nozzle jet, or other
methods; Setting a fluidized inflation plate layer at the bottom
can allow the material to be discharged from the upper part of the
tank, and the dispersion of the transported gas on different input
planes in the tank depends on the properties of the transported
material.
Positive pressure dense phase pneumatic conveying is a non
continuous conveying process, equipped with inlet and outlet
valves, material conveying pipelines, air input pipelines, and a
standardized silo pump. Before the silo pump feeds, the silo
contains the transported material, and all valves are closed.
The process of all positive pressure dense phase pneumatic
conveying operations is as follows:
1. Open the feed valve and exhaust valve, and the bin pump will
feed at normal pressure until the level gauge announces that the
bin is full and the indicator signal stops;
2. Close the feed valve and exhaust valve, and then open the
high-pressure air valve to pressurize the tank;
3. When the operating pressure is reached, open the delivery air
valve and discharge valve, and the material begins to be delivered;
4. The conveying end is displayed by the pressure switch, level
gauge, or time relay. At this moment, the high-pressure air valve
and discharge valve are closed, so that all compressed air is used
to clean the conveying pipeline; Open the exhaust valve together to
reduce the pressure inside the tank to normal pressure. After one
homework cycle is completed, the other cycle continues.
