with a fairing 30; the lower end of the cyclone 11 through the spool valve 31 and the pipe 28 is connected to the sludge container 7. The head 32 of the tank 2 is connected via an overflow device by a pipeline 33 to a spool valve 34, to a bath 6 by a pipe 35, and with a capacity of 8 oil waste by a pipe 36; the settling tank 7 is installed in the pan 37, the overflow from the settling tank 7 passes through the opening 38, covered by the grid 39, into the zone separated from the rest of the bath by a partition 40, at the bottom of which there is a removable window 41 perforated by the holes. Refilling with detergents is carried out through the hatch 42 directly into the bath 6. The outlet from the tank 2 to the spool 16 is located above the tubes of the heat exchanger 3. The distance from the outlet from the tank to the level sensor 43 should provide a liquid volume slightly larger than the working volume of the bath in order for the system to gnalizatsii warned that a new filling. The height distance from sensor 43 to sensor 44 is selected on the basis of the reserve of the supply volume of washing liquid from the fueling station. The filling of the tank 2 with water is carried out via a conduit 45, ending with a branch pipe (Fig. 4).

The device works as follows.

Before the start of washing, the prepared, heated washing solution from the tank 2 through the spool valve 16 through line 17 fills the bath to a level that is subsequently automatically maintained with the help of level detectors. Pump 10 washing solution through the nozzle system disposes the disordered streams onto the objects being washed in continuous movement in chamber 1. Selected washing solution flows into bath 6. Simultaneously, cleaning solution from pump 6 is pumped out through the spool, 22 pipeline 23 to hydrocyclone 11, pipeline 12 to tank 2, and from the lower suspension exit through spool valve 31 via pipeline 28 to the sump 7. Separate the liquid through the overflow device and opening 38, ytoe grating 39 overflows baffle 40 bath for 6 to the zone of action of the suction pump. After the end of the wash, the pump 9 operates until the cleaning solution is completely pumped out of the bath 6. The sump in the tapered part of the tank 2 is screwed periodically through the spool valve 26 by pipe 27 (28) into the sump 7. When the screw 4 and spool valve 26 is turned on the spool valve the valve 31 closes the pipe 28 in order to avoid washing liquid from the tank 2 with possible clogging of the pipe 27 (28). Washed petroleum products with synthetic detergents give a rapidly disintegrating emulsion. Pop-up petroleum products are collected at the top and, when the tank is filled with water, are squeezed out through the cap 32, the overflow device through conduit 33, the spool valve 36 into the tank 8. The refill of consumed cleaning solution is performed in the next order. Having replenished the tank 2 with water through the pipeline 45, squeezing out the oil products, we heat the tank and fill the bath 6 from the tank 2. Through the hatch 42 we introduce a synthetic detergent mixture to the volume of the spent solution, after dissolving we pump the pipeline 21 with the pump unit 9 through the spool distributor 22 through the pipeline 24 per tank 2.

Performing a bath form with a suction zone reduces the possibility of contaminants getting into the main tank volume,

Q contributes to the supply to the working chamber of a clean detergent solution, which improves the quality of cleaning.

Supplying the ends of the pipelines for supplying the spent working solution from the tank and the hydraulic cylinder to the sump drains out the fluid energy, which ensures that there is no disturbing effect on the solution in them, which contributes to better sedimentation of contaminants and, consequently, improves the quality of cleaning.

The implementation of water supply pipelines and a clarified washing solution from a hydrocyclone with sockets at their ends and a screen contributes to a better distribution of the liquid throughout the tank and better mixing of the solution, which also improves the quality and productivity of cleaning.

Feeding the solution into the tank from the bath through a pipe with a screen at the end ensures a decrease in kinetic energy 0 and also improves the process of separating contaminants from the solution.

Supply the solution supply pipe to the bath with a filter-shaped tip and the connection of this filter to the suction inlet of the circulation pump 5 ensures that the remaining suspension in the filter is held and the clean solution is fed into the working chamber, which also improves the quality of cleaning.
