Air Lift Pump

The air lift pump is a low-pressure dilute-phase pneumatic conveying equipment, primarily used for the enclosed conveying of powdery and fine granular materials. It is widely applied in industrial manufacturing, chemical industry, building materials, electric power and other fields, especially suitable for long-distance or multi-point conveying of cement, raw meal, fly ash, chemical powder and other materials. It is a key equipment in the "material transfer" process in industrial production.

Core Function

It replaces traditional equipment such as screw conveyors and bucket elevators, solving problems such as dust pollution, material caking and low conveying efficiency during the conveying of powdery materials, and achieving "enclosed and environmentally friendly" material transfer.

Working Principle

1. Feeding stage: Material enters the feed inlet of the air lift pump through bins, chutes and other devices, and falls by gravity to the upper part of the fluidizing chamber inside the pump body.

2. Fluidization and pressurization: Low-pressure air (provided by roots blower or air compressor) passes through the fluidizing device at the bottom of the pump body to "fluidize" the material (making the material flowable and reducing friction resistance).

3. Material seal to prevent leakage: Material accumulation inside the pump body forms a "material seal layer", which prevents high-pressure air from leaking backward while ensuring continuous and stable material entry into the conveying channel.

4. Pneumatic conveying: The fluidized material is pushed by airflow thrust through the conveying pipeline to the destination (such as storage silos, batching silos, production equipment feed inlets). The air-solid separation is achieved through a separator (such as a cyclone separator), the material is collected by settling, and the air is discharged within emission standards or recycled.
