Claims9
An apparatus for evacuating the interior of a tank during a procedure of pneumatically loading particulate material into the tank, comprising:
- a vacuum pump;
- means for connecting the vacuum pump to an interior of the tank such that the pump withdraws air from the tank via a stream of fluid;
- and
- at least a first filter unit located within the fluid stream between the tank and the vacuum pump for removing particulate matter from the fluid stream and returning it to the tank, the filter unit being physically located within the tank;
- wherein the tank includes at least one standard manhole therein having a diameter of approximately twenty (20) inches, said filter unit being designed, sized and arranged to be located entirely within the periphery of said standard manhole.
An apparatus for evacuating the interior of a tank during a procedure of pheumatically loading particulate material into the tank, comprising:
- a vacuum pump;
- means for connecting the vacuum pump to the interior of the tank such that the pump withdraws air from a first tank via a stream of fluid;
- at least one filter unit located within the fluid stream between the tank and the vacuum pump for removing particulate matter from the fluid stream and returning it to the tank, the filter unit being physically located within the tank;
- and
- further comprising a canister that surrounds sides and bottom of the filter unit, thereby separating the filter unit from the interior of the tank;
- wherein the tank has a manhole therein and the canister and filter unit are located within the periphery of the manhole.
