Overview of pneumatic lift pump
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 and chemical industries, and is a low-pressure pneumatic conveying device for conveying powdery materials such as cement, raw materials, fertilizers, coal powder, aluminum and magnesium powder.
Pneumatic lifting pump is a kind of low-pressure air conveying equipment, which is suitable for continuous and uniform vertical lifting and conveying of dry powdery materials. Its conveying capacity is large and the lifting height is high. TL series pneumatic lifting pump is a pneumatic vertical conveying lifting material. Equipment, mainly used to transport cement, pulverized coal and other powder materials. It can be used instead of a hoist. It is more economical to use when the hoisting height exceeds 30m, but when the hoisting height is less than 20m, the power consumption is higher than the hoist. The equipment has a simple structure, convenient and reliable operation, no dust, and low wear and tear of parts and components for easy maintenance.
Working principle of pneumatic lift pump
The characteristics of the pneumatic lifting pump for conveying materials are to utilize the characteristics of the materials and to use the automatic compensation of the materials to carry the materials vertically. 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 the middle space is provided with a porous ventilation plate. 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 fluidized 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 inlet pipe of the pneumatic lift pump, and at the same time adjust the ball valve on the fluidized air duct, so that the material is fully fluidized in the fluidization bin below the lift pump. At this time, when the pressure of the air source supplied to the air inlet pipe reaches the rated value, the traction generated by the high-speed air flow ejected from the nozzle guides the powdered material that has been fluidized along the conveying pipe in the center of the pump body and the external pipe to rise to Desired height. Under continuous working conditions, the output can reach 200T / H and the height can reach 60M.
