NON-CLOGGING AIRLIFT PUMPS AND SYSTEMS AND METHODS EMPLOYING THE SAME

摘要

Non-clogging airlift pumps and associated systems and methods employing said pumps. The airlift pumps generally include an enclosed air tank within which is located a hollow cylinder having an open top and a closed bottom wall. A gas (e.g., air) line passes into the air tank for supplying gas thereto. A suction port is located in the bottom wall of the cylinder, and a substantially vertically-oriented discharge pipe passes through a top wall of the air tank such that an intake end of the discharge pipe resides within the cylinder. Multiple airlift pumps may be used in conjunction in a given application.

主权项

1. A non-clogging airlift pump, comprising:
an enclosed air tank; a gas input line passing into the air tank; a hollow cylinder located within the air tank, the cylinder having an open top and a closed bottom wall; a drain port passing through the bottom wall of the cylinder, a drain tube extending downward some distance therefrom; and a substantially vertically-oriented discharge pipe passing in a sealed manner through a top wall of the air tank at a location that is axially offset from the location of the drain port, an intake end of the discharge pipe residing within the cylinder and at some distance above the bottom wall thereof.
