BACKGROUND OF THE INVENTION

The current system is configured to be used on a vacuum truck or other truck with a tilting mechanism for dumping liquids or other contents. In the preferred embodiment, it may be used with a vacuum truck but the system is not limited to such use.

A vacuum truck or vacuum tanker is a type of tank truck that has a pump designed to pneumatically load liquids, sludges (such as fecal sludge) or slurries so that the material can be transported to a treatment or disposal site. They are mainly used to transport sanitary waste (human excreta mixed with water, e.g. from on-site septic tanks) as well as for some industrial liquids or slurries.

Design and Configurations

Commercial vacuum trucks which collect fecal sludge usually have a volume of 10-55 cubic meters. However various smaller versions for specialized applications or low-resource settings can be found with tanks as small as 500 liters.

Pumps

They generally use a low-volume sliding vane pump or a liquid ring pump to create a negative air pressure. The use of diaphragm mud pumps is less common, but with the advantage of a simpler design and usually lower overall costs. The disadvantage is that mechanical parts come into contact with the sludge, which is not the case for the more common vacuum pumps.

The truck can be configured to be a direct belt drive, or a hydraulic drive system. There are two different ways to mount the pump: either directly on the truck with the vacuum drive powered by the truck motor, or on the trailer with an independent motor. The more complicated trailer mounted version allows the utilization of both the negative pressure suction side of the pump as well as the positive pressure side to pump sludge over longer distances or lift it higher into the tank.

Suction Hoses

The suction hoses are typically 2 to 4 inches (5.1 to 10.2 cm) in diameter with 3″ or 3 inches (7.6 cm) being the norm. The possible length depends on various factors mainly related to the lift and other pressure losses; Rarely will it be possible to extend it more than 50 m.

An inherent suction limitations of all suction pumps is that can only lift a liquid through utilizing atmospheric pressure (for pure water the theoretical maximum lift is approximately 10.3 m (33.9 feet)). However due to the viscosity of sludge it is possible to mix air into it either by sucking close from the surface or adding air with a compressor through a separate hose. Through this the overall density of the sludge/air mixture can be reduced a bit below that of pure water and thus a somewhat higher lift (10-15 m) be reached under optimal conditions. Other factors effecting the possible lift and total length of the suction hose are that single stage vacuum pumps only reach an 85-90% partial vacuum and that small air leakages, pipe friction losses and the viscosity of the liquid further reduce the possible lift.

Vacuum trucks are used by town, and municipal, governments, and by commercial entities around the world.

Human Excreta

Several types of non-centralized sanitation systems are served by vacuum trucks. They are used to empty septage from cesspits, septic tanks, pit latrines and communal latrines, for street cleanup, for sewer clean out, and for individual septic systems. The trucks are used in the cleaning of sanitary sewer pumping stations. Vacuum trucks are used to empty portable toilets. In commercial aviation, vacuum trucks are used to collect waste from airplane toilets.

Vacuum trucks discharge these wastes to the sewer network, to a wastewater treatment plant, or—usually illegally, for example in many developing countries—into the environment. The latter practice, called “institutionalized open defecation”, is dangerous since it constitutes a public health and environmental hazard.

Industrial Liquids

Vacuum trucks are used in the petroleum industry, for cleaning of storage tanks and spills. They are also an important part of drilling oil and natural gas wells, as they are located at the drilling site. Vacuum trucks are used to remove drilling mud, drilling cuttings, cement, spills, and for removal of brine water from production tanks. They dispose of this in sump pits, treatment plants or if within safe levels may be spread out in a farmer's field.

Others

Vacuum trucks are also used for exposing underground utilities. The ground is jetted with water, and the vacuum truck sucks up the muddy product. This exposes the buried utility without the possibility of damage, as would be possible if a digging machine were used (i.e. tractor backhoe, tracked or wheeled excavator, ditch witches).

Vacuum trucks can also be used for cleanup of contaminated soil.

Said two sidetracks306each comprise said L-bracket1000and a track assembly1002. Said L-bracket1000comprise an L shaped bracket configured for attaching to said side portions114of said trailer platform104.

Said two sidetracks306comprise a separation width328between said first sidetrack306aand said second sidetrack306b. Said lower guides310comprises a width814. Said width814is wider than said separation width328. Portions of said lower guides310can become trapped within portions of said two sidetracks306.

A fastener assemblies318comprise said upper axis320of said body prop assembly102.

Said vessel hinge brackets314and said prop hinge brackets316comprise one or more hinge eyes702to receive a portion of a fastener assemblies318.

A track assembly1002comprise an upper level1006and a lower level1008. Said upper level1006and said lower level1008are substantially parallel planes with provisions for moving said lower guides310freely above said upper level1006and selectively at said lower level1008. Portions of said track assembly1002are welded to said L-bracket1000. Said guide tracks500is constructed of said upper level1006, said lower level1008, a second flap1026, a first flap1024. Said guide tracks500defines a space above said lower level1008which allows said lower guides310to move relatively freely, a gap1114for allowing said lower guides310to pass freely below said lower level1008and into a lower mid portion1018, and a trap1016for holding a portion of said lower guides310. Said lower guides310is configured to enter said lower level1008through said gap1114between a rear upper portion1012and an upper mid portion1030, slide down a rear ramp1014, slide between said upper mid portion1030and said lower mid portion1018. Slide into said trap1016. Portions of said track assembly1002are configured to allow one-way movement of said lower guides310into and out of said trap1016. Said lower guides310are configured to slide into said first flap1024, lift a portion of said first flap1024, slide into said trap1016, closing said first flap1024behind said lower guides310so as to selectively hold a portion of said lower guides310in said trap1016, and said lower guides310selectively remains in said trap1016provided downward force is exerted on said body prop assembly102. Said body prop assembly102is configured to act as a prop for said tilting portions106. Removing a portion of said lower guides310from said trap1016comprises reversing said lower guides310into a portion of said first flap1024, sliding up said first flap1024, opening said second flap1026, and sliding said lower guides310out of said lower level1008and onto or above said upper level1006. Said first flap1024is configured to selectively pivot on a first hinge1020. Said second flap1026is configured to selectively pivot on a second hinge1022. Said body prop assembly102is configured to lift said lower guides310entirely off of said two sidetracks306with said tilting portions106raised sufficiently above said lower guides310. With said lower guides310lifted off of said two sidetracks306, a body width802/are configured to press into said bottom116dof said tilting portions106and thereby prevent rotation of said body prop300.

Said upper portion322is substantially parallel with said lower guides310. Said side portions324is substantially perpendicular to said lower guides310. Said side portions324is substantially perpendicular to said upper portion322.
