Bin pump

There are two unloading methods for bin pump, of which bottom discharging is a common method. The materials in the tank are fluidized by means of air inflation in the conical aeration tank, nozzle air jet or other methods; Fluidized aeration plate (layer) is arranged at the bottom to discharge materials from the upper part of the tank. The distribution of transported gas on different input planes in the tank depends on the properties of transported materials.  

Operation process of bin pump

(1) Open the feed valve and exhaust valve, and the bin pump will feed under normal pressure until the level gauge sends out a full bin indication signal;

(2) Close the feed valve and exhaust valve, and then open the high-pressure gas 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 end of conveying is indicated by the pressure switch, level gauge or time relay. At this time, close the high-pressure gas valve and discharge valve, so that compressed air is used to purge the transmission pipeline; At the same time, open the exhaust valve to reduce the pressure in the tank to normal pressure. After one work cycle is completed, another cycle continues.
