For Fly Ash Coke Powder
Pneumatic Conveying Bin Pump Application Area
PCD pneumatic conveying equipment and systems have been widely used
in industries such as building materials, chemicals, mining,
electricity, and metallurgy. The conveying materials include
cement, raw materials, fly ash, hydrated lime, dry discharged
calcium carbide slag, slag powder, steel slag powder, coal powder,
aluminum oxide powder, bauxite powder, phosphorus powder,
pyrophyllite powder, and organic silicon powder.
The silo pneumatic conveying pump adopts a positive pressure
pneumatic conveying method to transport powdered materials, and is
widely used in the transportation of materials such as fly ash,
cement, cement raw materials, and mineral powder in power plants.
Transportation pipelines can be flexibly arranged according to
terrain conditions to achieve centralized, dispersed, high
altitude, and long-distance transportation. The transportation
process is not affected by natural conditions, ensuring that
materials are not affected by moisture and are environmentally
friendly and pollution-free. This equipment adopts a PLC control
system, which can be automatically or manually controlled. After
long-term practical operation, it has been proven that the
equipment has stable performance, reliable quality, and no dust
pollution during transportation, making it an ideal pneumatic
conveying equipment.
There are two discharge methods for bin pumps, among which bottom
discharge is the most commonly used method. The materials in the
tank can be fluidized through the conical surface inflation groove,
nozzle jet, or other methods; Setting a fluidized inflation plate
(layer) at the bottom allows the material to be discharged from the
upper part of the tank. The distribution of transported gas on
different input planes in the tank depends on the properties of the
transported material.
Warehouse pump conveying is a discontinuous conveying process. The
figure shows a standard compartment pump with inlet and outlet
valves, material conveying pipelines, air input pipelines, and a
silo. Before feeding into the silo pump, the silo is filled with
the conveyed material, and all valves are closed. The entire work
process is as follows:
(1) Open the feed valve and exhaust valve, and feed the silo pump
at atmospheric pressure until the horizontal level gauge sends a
signal indicating full silo;
(2) Close the feed valve and exhaust valve, then open the
high-pressure air valve to pressurize the tank;
(3) When the operating pressure is reached, open the conveying air
valve and discharge valve, and the material begins to be conveyed;
(4) The conveying end is displayed by the pressure switch, level
gauge, or time relay. At this time, close the high-pressure air
valve and discharge valve, so that all compressed air is used to
clean the conveying pipeline; Simultaneously open the exhaust valve
to reduce the pressure inside the tank to normal pressure.
After one work cycle is completed, the other cycle continues.
The working principle of the electric plug valve is to receive
control commands, electrically open the plug valve, and carry out
ash discharge work.
