Liquid waste application system with sludge gun

Claim 2

Apparatus for surface applying a relatively viscous liquid at long distances, comprising in combination: a. a mobile distribution tank for containing a quantity of a relatively viscous liquid; b. means operative during a discharge mode for maintaining a positively pressurized condition in said tank; c. means operative during the discharge mode for pumping said viscous liquid from said tank at flow rates of several hundreds of gallons per minute and during which said pressurization means sufficiently pressurizes said tank to prevent pump cavitation; and d. turret mounted nozzle means receiving the pumped liquid for controllably and directionally surface applying the liquid at distances in excess of one hundred feet from said tank.

Claim 3

Apparatus as set forth in claim 1 including an inlet port and means operative during a loading mode for negatively pressurizing said tank so as to vacuum load said tank from a larger storage resevoir.

Claim 4

Apparatus as set forth in claim 1 wherein said means for positively and negatively pressurizing said tank comprises an air pump coupled to pump air from said tank during a loading mode and to pump air into said tank during a discharge mode.

Claim 5

Apparatus as set forth in claim 1 wherein said turret mounted nozzle means includes hydraulic means for rotatively and elevationally adjusting the distribution angle of a liquid discharge nozzle.

Claim 6

Apparatus as set forth in claim 1 wherein said pump means comprises a substantially submerged, hydraulically driven centrifugal pump.

Claim 7

Distribution apparatus for surface applying relatively viscous liquid soil treatment materials comprising in combination: a. a mobile distribution tank for containing a quantity of soil treatment materials, including in excess of 10% solids, under positive and negative pressure conditions; b. means for transporting said tank over a variety of ground conditions and terrains; c. air pump means selectively operable during a loading mode for vacuum loading said tank and for alternatively pressurizing said tank, during a distribution mode; d. an inlet port coupled to said tank for receiving treatment materials from an external source during said loading mode; e. pump means operative during said distribution mode for pumping said treatment materials from said tank at flow rates of several hundreds of gallons per minute; and f. a turret mounted, hydraulically directionally controllable sludge gun for receiving the pumped materials and ejecting the treatment materials over distances in excess of one hundred feet during said distribution mode in a clog and cavitation free manner.

Claim 8

Distribution apparatus for surface applying relatively viscous liquid soil treatment materials comprising in combination: a. a mobile distribution tank for containing a quantity of soil treatment materials, including in excess of 10% solids, under positive and negative pressure conditions; b. means for transporting said tank over a variety of ground conditions and terrains; c. air pump means selectively operable during a loading mode for vacuum loading said tank and for alternatively pressurizing said tank, during a distribution mode; d. an inlet port coupled to said tank for receiving treatment materials from an external source during said loading mode; e. pump means operative during said distribution mode for pumping said treatment materials from said tank at flow rates of several hundreds of gallons per minute; and f. a turret mounted, hydraulically directionally controllable sludge gun for receiving the pumped materials and ejecting the treatment materials over distances in excess of one hundred feet during said distribution mode in a clog and cavitation free manner.

Claim 9

Apparatus as set forth in claim 6 wherein said transport means includes a hydraulically actuable dozer blade for light duty clearing of the area to be traversed.

Claim 10

Apparatus as set forth in claim 6 wherein said pump means comprises a hydraulically driven centrifugal pump.
