TL pneumatic lift pump is
used to convey the powdery material that can be aerated and fluidized without segregation through a vertical pipeline to a relatively high level separator or silo. Under continuous working conditions, the output can reach 200T / h , with a height of up to 60 meters, is widely used in building materials, chemical industries and other low-pressure pneumatic conveying equipment for conveying powdery materials such as cement, raw materials, fertilizers, coal powder, aluminum and magnesium powder.
The characteristics of TL pneumatic lift pump for conveying materials are to utilize the characteristics of materials and to use the automatic compensation of materials to convey materials vertically.
TL pneumatic lift pump conveying system is mainly composed of three parts: pump body, conveying pipeline and air source. The pneumatic lift pump has a small footprint, convenient installation, reliable operation and simple operation. The equipment itself has almost no wear during operation. There is no pressure inside the pump body, so the upper feeding pipe does not need the air lock device; and the lifting pump can also overcome the fluctuation of the feeding caused by the uneven feeding of the feeding equipment.
Pneumatic lift pump is used to convey the powdery material that can be fluidized without segregation through a vertical pipeline to a high-level feeder separator or silo. In the case of continuous transportation, the output can reach 200T / h . It can reach a height of 60 meters and is widely used in building materials and chemical industries. It is a low-pressure pneumatic conveying device for conveying powdery materials such as cement, raw materials, fertilizers, coal powder, aluminum and magnesium powder.
The pneumatic lifting pump conveying system is mainly composed of a pump body, a conveying pipeline and an air source. The material is continuously fed into the pump body through the charging port 9, and the compressed air is sprayed into the conveying pipe 3 through the nozzle 2 through the main air pipe 4. Due to the high jet velocity of the air, a low pressure area is formed between the nozzle 2 and the conveying pipe 3, and the material is continuously brought into the conveying pipe 3 by the air flow. In order to increase the pressure of the material in the lower part of the pump body and fluidize it, secondary air with a total air volume of about 5% is introduced through the inflation pipe 5. The secondary air passes through the inflation chamber 6 and is filled into the material through the perforated plate 7. In order to prevent the main air pipe 4 from being blocked due to accidental shutdown due to material accidents, an electronically controlled pneumatic pressure reducing valve 10 can be provided on the main air pipe 4. The gas stored in the main air pipe when the machine is stopped causes the check valve 8 to close quickly and immediately Dissipated by the pressure reducing valve 10, so that the pressure of the gas under the check valve 8 is reduced.
Working principle of TL pneumatic lift pump
<BR> The pneumatic lift pump is equivalent to a low-pressure fluidized storage tank. The upper part of the lift pump is the pump body, the lower part is the gasification chamber, and there is a porous ventilation plate in the middle. The primary air outlet is equipped with a nozzle and aligned with the conveying
pipe: the lower outlet of the conveying
pipe is equipped with an expansion bin, the secondary air is connected to the gasification chamber, and the ash is blown up to form a paralyzed state through the ventilation layer ; The compressed air flow from the nozzle is conveyed upward through the riser. The air volume is adjusted by a ball valve, and the air source is supplied by a Roots fan. Open the air source valve to supply air to the air intake pipe of the pneumatic lift pump, and adjust the ball valve on the fluidized air duct to make the material fully fluidize in the fluidization tank at the lower part of the lift pump. When the pressure reaches the rated value, the traction generated by the high-speed air flow from the nozzle guides the powdered material that has been fluidized to the required height along the conveying pipe in the center of the pump body and the external pipe.
1. Easy to implement centralized control and automation of the system. The conveying speed is fast and the conveying capacity is large, up to 500t / h .
2. Short delivery time, which can reduce the loading and unloading time of vehicles and ships, and has high efficiency.
3. The powder can be conveyed in a concentrated or dispersed manner over a long distance, and the conveying distance can reach 2000m .
4. The entire transportation process is completely sealed, not affected by the climate, does not pollute the environment, and has no noise.
5. The material sealing pump has fewer equipment parts, compact structure, flexible process layout, and does not occupy the area of use.
