The walking assembly is disposed in the rack and fixedly connected to the rack through a bearing. The power unit is disposed on the rear end of the rack. An oil tank is provided with a hole. The truss assembly is configured to place the robot into the oil tank through the hole. The walking assembly is configured to drive the robot to move along the axis of the oil tank and to prevent the robot from toppling in the oil tank. The power unit is configured to clean the inside of the oil tank. The walking assembly includes two active walking assemblies, a drive assembly, and a folding assembly.

The present invention relates to a modular cleaning hydrocarbon storage tanks system, as well as a cleaning process which allows recovering crude oil from the waste sludge contained in the hydrocarbon storage tanks. Moreover, the present invention relates to the use of chemical mixtures applied during the hydrocarbon storage tanks cleaning process. The invention allows the recovery of crude oil from the waste sludge contained in said tanks.

A device and process for cleaning and decommissioning used chemical jugs or containers of any size, including an upper positioned clean water manifold which feeds a pressurized inlet fluid to a vertically downwardly arrayed elongated and spike shaped component having a sharpened lower end, the spike shape component being downwardly actuated for successively piercing at least one wall of the container. The hollow spike shaped component also includes a plurality of laterally and/or angularly positioned pressurized fluid outlets for issuing fluid evenly across the inside surface area of the jug for subsequent drainage through a pierced bottom of the jug.

Apparatus for cleaning a surface with a liquid jet, the apparatus having: a primary fluid conduit having a longitudinal axis and two ends, a fluid-intake end and a fluid-exit end; a first motor-driven drive assembly configured to engage the primary fluid conduit and turn the primary fluid conduit about the primary-fluid-conduit longitudinal axis; a first motor configured to engage the first motor-driven drive assembly; a section of the primary fluid conduit being inside of an adjacent penetration sleeve; a section of the penetration sleeve being inside of a piston sleeve; the piston sleeve configured to engage the penetration sleeve and move the penetration sleeve back and forth along a penetration-sleeve linear path over a primary-fluid-conduit exterior surface; an actuator configured to engage the piston sleeve and move piston sleeve back and forth along a piston-sleeve linear path; a penetration-sleeve end being attached to an extension sleeve that has a first end and a second end; the extension-sleeve second end being attached to a pull rod or a pull cable; the pull rod or the pull cable being attached to a nozzle anchor and configured to pull on, push against, or release tension from the nozzle anchor as the penetration sleeve moves back and forth along the penetration-sleeve linear path; the primary-fluid-conduit fluid-exit end being attached to a flexible conduit; the flexible conduit being attached to a nozzle tip having the nozzle anchor thereon; and a continuous fluid-flow channel that extends from the primary-fluid-conduit fluid-intake end through the flexible conduit.

A washer assembly for cleaning used chemical containers having a sealed chamber with a hingedly attached lid. A spray tube is supported in upright extending fashion upon a pan shaped basin of the sealed chamber. A fresh fluid inlet feeds pressurized fluid flow to the spray tube for spraying an inside of the chemical container placed over the tube, such that the fluid collects upon the basin. A drain is incorporated into the basin for removing contaminated fluid from the chamber.

A fluid cleaning device includes a spheroid-shaped member defining an internal void. The spheroid-shaped member further includes a wall defining a plurality of apertures and at least partially surrounding the internal void and an inlet orifice that receives a cleaning fluid under pressure. A tubular nozzle projects from the inlet orifice and into the internal void to mitigate fluctuation of one of the internal pressure and flow velocity of the cleaning fluid within the spheroid-shaped member.

The present invention relates generally to a method to determine one or more properties in a water storage facility and/or a water treatment facility. In one embodiment, the present invention relates to a method to determine one or more chemical and/or physical properties in a water storage facility vessel and/or a water treatment facility vessel and then use such one or more chemical and/or physical properties to determine where, if need be, any sand or other sediment needs to be removed from any such water storage facility vessels and/or a water treatment facility vessels.

An inner membrane removing device includes a heating membrane removing mechanism and a membrane suction mechanism located at a downstream of the heating membrane removing mechanism. The heating membrane removing mechanism includes a heating frame, a membrane pressing component, a membrane welding component configured to fusion weld a nest box inner membrane to a nest box inner lining paper, a first lifting component configured to enable the heating frame and the membrane welding component to be in contact with the nest box inner membrane and a second lifting component configured to enable the membrane pressing component to press against the nest box inner membrane. The membrane pressing component and the membrane welding component are located on an inside of the heating frame. An inner membrane removing method is also provided.
