Abstract
A vacuum tank with a rear door, and air and material hoses connectable to the tank door. The tank is rotatable, while the door remains stationary. Liquid, particulate, or slurry material can be vacuumed into the rotating tank, without twisting the hoses. Additional water and/or drying agent can be added to the tank to create a slurry mixture, which can then be discharged from the tank at a convenient dump or work site. The tank may be mounted on a truck, trailer, or frame for transport to a job site and the dump or work site. In an alternative embodiment, the tank may be tilted end-to-end between fill and discharge positions.
Claims21
A vacuum tank for liquid and particulate materials, comprising:
- a rotatable tank having front and rear ends;
- a drive assembly operably connected to the front end to rotate the tank;
- a door on the rear end;
- ports on the door;
- hoses connected to the ports to vacuum materials into the tank and to discharge materials from the tank;
- and
- a vibrator connected to the tank to facilitate emptying of material from the tank.
A vacuum tank for liquid and particulate materials, comprising:
- a rotatable tank having front and rear ends;
- a drive assembly operably connected to the front end to rotate the tank;
- a door on the rear end;
- ports on the door;
- hoses connected to the ports to vacuum materials into the tank and to discharge materials from the tank;
- and
- a frame to support the tank for end-to-end tipping between inclining and declining positions.
A container assembly for liquid and particular materials, comprising:
- a rotatable and pivotal tank;
- a material inlet and a material outlet on one end of the tank;
- wherein the tank is pivoted in one direction to receive the materials via the inlet and pivoted in an opposite direction to discharge the materials,
- a frame to support the tank for rotation about a longitudinal axis and pivoting about a lateral axis;
- and
- a weigh scale on the frame to weigh the tank.
A vacuum tank for liquid and particulate materials, comprising:
- a rotatable tank having front and rear ends;
- a drive assembly operably connected to the front end to rotate the tank;
- a door on the rear end;
- ports on the door;
- hoses connected to the ports to vacuum materials into the tank and to discharge materials from the tank;
- and
- a swivel connection between the door and the tank to allow the tank to rotate without the door rotating.
