Low Power Consumption PCD Type Positive Pressure Dense Phase Pneumatic Conveying Bin Pump
Product Introduction:
Principle of PCD type positive pressure dense phase pneumatic
conveying bin pump: There are two unloading methods for bin pumps,
with bottom discharge being the most commonly used method. The
materials in the tank are fluidized through a conical surface
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. The distribution of
transported gas on different input planes in the tank depends on
the properties of the transported material.
The silo pump conveying is a discontinuous conveying process.
1. Open the feed valve and exhaust valve, and the bin pump will
feed at normal pressure until the horizontal level gauge sends a
signal indicating the full bin;
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 point, 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.
Pneumatic Conveying Pump Advantages:
1. High energy efficiency:
Due to the reasonable fluidization structure and good material
fluidization state, the gas consumption is significantly lower than
similar products, greatly improving production efficiency and
reducing energy consumption.
2. High material to gas ratio:
Good fluidization effect, low gas consumption, and higher material
to gas ratio. Through laboratory testing, the equivalent distance
is within 500 meters, and the material to gas ratio reaches over
30Kg (ash)/Kg (gas).
3. Low material flow rate:
Due to low air consumption and high material to gas ratio, the
material moves in a partial flow in the pipeline, achieving dynamic
and static pressure transportation. Therefore, the flow rate during
material transportation is low, the wear of equipment valves and
pipelines is small, and the service life of vulnerable parts is
long.
4. Strong adjustment function:
Equipped with various adjustment methods such as primary and
secondary air intake regulation, the system can operate under the
optimal air consumption ratio and excellent fluidization state.
5. Unique blockage removal method:
Adopting a reverse suction blockage removal method is simple, easy
to operate, and operates reasonably. It only requires the mixture
of material and gas to be led to the inlet of the silo or flue
through the blockage removal valve and pipeline.
6. Easy to solve supporting facilities:
Due to its low gas consumption and low speed, the material and gas
separation and filtration equipment in the silo can be smaller than
those equipped with general silo pumps, resulting in less air
pollution.
7. Low energy consumption coefficient:
The energy consumption coefficient of the silo pump conveying
system is below 65KW. h/t. m.
8. High degree of automation:
The programmable logic controller (PLC) control system is adopted,
and the entire working process can be fully automated. The system
can be set to automatic or manual operation mode. The main control
cabinet is installed in the system control room.
