Product Specification

Pneumatic Conveying Bin Pump For Long-Distance And Large Capacity Transportation

Description

Industrial equipment for conveying powdered materials
The pneumatic conveying silo pump adopts a positive pressure pneumatic conveying method to transport powdered materials, and is widely used for conveying materials such as fly ash, cement, cement raw materials, mineral powder, etc. in power plants. The transportation pipeline can be flexibly arranged according to the terrain conditions, achieving 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. It is an ideal pneumatic conveying equipment.
Positive pressure concentrated phase pneumatic conveying bin pump principle
There are two unloading methods for silo pumps, with bottom discharge being the most 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. 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 (see attached figure). This figure shows a standard silo pump with inlet and outlet valves, material delivery pipelines, air input pipelines, and a silo. Before the feeding of the silo pump, the silo is filled with the conveyed material, and all valves are closed. The entire working process is as follows:
(1) Open the feed valve and exhaust valve, and the bin pump will feed at atmospheric 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.
After one work cycle is completed, the other cycle continues.
The working principle of the electric gate valve is to receive control commands and electrically open the gate valve for ash discharge.

Main Features
1. High energy efficiency
Due to the reasonable fluidization structure, good material fluidization state, and significantly lower gas consumption compared to similar products, our company has made multiple improvements to the fluidization structure after years of production and research, 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
Our company adopts a reverse suction blockage removal method, which is simple, easy to operate, and operates reasonably. We only need to introduce the material and gas mixture to the silo or flue inlet 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 our warehouse 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.
