Abstract
A tank and a method of carrying a load and discharging a load therefrom. The tank includes a body having a first wall that bounds and defines a first compartment for carrying a load therein and a second wall spaced outwardly from at least a portion of the first wall; wherein a second compartment is defined between the first wall and the second wall. An air piping system is selectively actuated to place the first compartment and the second compartment under substantially similar or substantially equal air pressure. In one example the air piping system pumps air into the first compartment and the second compartment. In another example the air piping system evacuates air from the first and second compartments.
Claims21
A tank for holding a load;
- said tank comprising:
- a body;
- a first wall provided on the body;
- said first wall bounding and defining a first compartment that is adapted to carry a load of material therein;
- a second wall spaced outwardly from a portion of the first wall;
- wherein a second compartment is defined between the first wall and the second wall;
- a first opening and a second opening defined in the first wall and being located to selectively place the first compartment in fluid communication with air outside of the body;
- wherein the first opening is adapted to permit introduction of the load of material into the first compartment;
- and the second opening is adapted to permit removal of the load of material from the first compartment without the load of material entering the second compartment;
- and
- an air piping system engaged with the body;
- wherein the air piping system is selectively activated to pressurize the first compartment and the second compartment or to create a vacuum in the first compartment and the second compartment.
