MOBILE TECHNOLOGICAL COMPLEX OF HARD TANKS CLEANING AND WASHING Russian patent published in 2017 - IPC B08B9/08 B08B9/93 

FIELD: technological processes.

SUBSTANCE: technological complex comprises a volume pump 1 with a washing liquid supply tank 2 connected with a flexible hose 4 to spray devices and arranged on a trolley made as a movable articulated frame structure fixed to a suction pipe 18 with a hydraulic valve 19 and a diffuser 20. On the suction pipe 18 there is a platform 22 for control equipment 23 fixing on it which is made in the form of adjustable and nonadjustable throttles and spool valves. A flexible conduit 17 is connected to the suction pipe 18 from the vacuum unit. The complex contains a hydraulic drive with a volume pump 6 and a tank 7 for working fluid. The hydraulic drive is connected with flexible hoses 9 and 14 through the control equipment 23 to the hydraulic motors 10 and 11 mounted on the wheelsets of the wheel set frames 21 and tracks connected to the driving wheels, the hydraulic cylinder 12 of the wheel decouplement (rollup) and to the hydraulic cylinder 13 of the rod 24 in the vertical plane. The rod 24 consists of removable sections. A comb with nozzles 25 is fastened on each section.

EFFECT: invention allows to exclude the presence of people inside the reservoir during the stripping process and to increase the efficiency and quality of stripping.
