一、 Structure
The pneumatic lift is made up of carbon box (air liquor separator ),suction carbon pipe (lifting pipe),air pipe and suction inlet (air liquor mixer),see the attached arawing.
二、 Operation principle
Capitalizing on the super elevation of liquid column generated when two kinds of liquid with different density connect with atmosphere in the connected vessel and the pressure density reaches natural balance, The pneumatic lift lifts the suspending liquid.
The attached drawing shows the pneumatic lift installed in the leaching tank. Compress air into the suction inlet through sir pipe and the slurry is uniformly mixed with compressed air in the suction inlet and the density depresses and then the density difference of the slurry occurs before and after mixed. The lower density slurry rise to the carbon box along the suction carbon pipe and air is discharged from the exhaust pipe at the top and the slurry are discharged from the pipe under the carbon box.
三、 Application
It is used for lifting high density materials such ad working medium in the enrichment plant of heavy medium and concentrate after thickening etc.
四、 Advantage and disadvantage
Compared with sand pump, its structure is simple, has to moving parts, The abrasion of lifting pipe is light, easy to maintain and easier to beep the integral carbon granule compared with carbon-lifting pump, But the efficiency is
low(commonly 20%-40%),It needs mating compressor and consumption of energy amount is higher than sand pump.
