Abstract
An automatic tank clean out system provided in the slurry collection tank a soil reduction system. When the slurry collection tank becomes full, the vacuum system is automatically shut down to prevent the slurry mixture from being drawn into the vacuum pump. When it becomes necessary to empty the slurry collection tank, the liquid contents can be drained through a valve in the tank. A series of nozzles, such as fan nozzles, are provided which are connected to a water supply pipe running axially through the tank. These fan nozzles are actuated to deliver high pressure water to automatically clean the tank.
Claims8
A tank cleaning apparatus for cleaning solids from the interior of a slurry tank, the slurry tank having a door through which the solids may be removed, the tank cleaning apparatus comprising:
- an elongated fluid delivery conduit for carrying pressurized fluid;
- a plurality of spray nozzles connected to said fluid delivery conduit, said spray nozzles being directed towards the interior of the slurry tank for delivering pressurized fluid to dislodge solids from the slurry tank;
- a first connector provided on the door of the slurry tank, and wherein said elongated fluid delivery conduit is positioned in the interior of the slurry tank and extends substantially the length of the slurry tank;
- and
- said elongated fluid delivery conduit having a second connector for cooperating with said first connector in order to seal the door to the slurry tank.
A tank cleaning apparatus for cleaning solids from the interior of a slurry tank, the slurry tank having a door through which the solids may be removed, the door being configured for closing and sealing of the slurry tank, the tank cleaning apparatus comprising:
- an elongated fluid delivery conduit for carrying pressurized fluid, said fluid delivery conduit being configured to connect to the door of the slurry tank;
- and
- a plurality of spray nozzles connected to said fluid delivery conduit, said spray nozzles being directed towards the interior of the slurry tank for delivering pressurized fluid to dislodge solids from the slurry tank;
- and
- wherein said elongated fluid delivery conduit is configured for connection to the door of the slurry tank and for being placed in tension upon closing and sealing of the door to the slurry tank.
A tank cleaning apparatus for cleaning solids from the interior of a slurry tank, the slurry tank having a door through which the solids may be removed, the tank cleaning apparatus comprising:
- an elongated fluid delivery conduit for carrying pressurized fluid;
- and
- a plurality of spray nozzles connected to said fluid delivery conduit, said spray nozzles being directed towards the interior of the slurry tank for delivering pressurized fluid to dislodge solids from the slurry tank;
- a first threaded connector provided on the door of the slurry tank, and wherein said elongated fluid delivery conduit is positioned in the interior of the slurry tank and extends substantially the length of the slurry tank;
- and
- said elongated fluid delivery conduit having a second threaded connector for cooperating with said first threaded connector in order to seal the door to the slurry tank.
A tank cleaning apparatus for cleaning solids from the interior of a slurry tank, the slurry tank having a door through which the solids may be removed, the tank cleaning apparatus comprising:
- an elongated fluid delivery conduit extending in and for substantially the length of the interior of the slurry tank for carrying pressurized fluid;
- a plurality of spray nozzles connected to said fluid delivery conduit, said spray nozzles being directed towards a lower portion of the interior of the slurry tank for delivering pressurized fluid to dislodge solids from the interior of the slurry tank;
- a first connector provided on the door of the slurry tank;
- and
- said elongated fluid delivery conduit having a second connector for cooperating with said first connector in order to seal the door to close the slurry tank.
A method of cleaning the interior of a slurry tank, the slurry tank having a door through which the solids may be removed, the method comprising:
- draining liquid portions of the slurry from the slurry tank;
- opening the door to the slurry tank and tilting the slurry tank for allowing loose solids to move towards the door;
- providing an elongated fluid delivery conduit for carrying pressurized fluid;
- fixing said elongated fluid delivery conduit in the interior of the slurry tank;
- providing a plurality of spray nozzles connected to said elongated fluid delivery conduit;
- and
- delivering pressurized fluid to said elongated fluid delivery conduit such that the pressurized fluid is emitted from said spray nozzles, said spray nozzles being directed towards a lower portion of the interior of the slurry tank for delivering the pressurized fluid to dislodge solids from the interior of the slurry tank.
