Description

The claimed invention relates to the field of external cleaning of tanks, in particular reservoirs for storing oil and oil products, but can be used for similar purposes in the external cleaning of stationary tanks.

The prior art device for washing smooth surfaces containing a vehicle in the form of two drive wheels located on the same axis of rotation with independent drives, a vacuum gripper located between the drive wheels and a pair of spring-driven driven wheels mounted in the plane of symmetry of the vehicle, and connected to the vehicle of the washing mechanism in the form of a hollow body, the open part facing the surface being treated, while the internal volume of the hollow body is connected to the means for supplying and removing the washing solution, the edges of the walls of the body are equipped with elastic seals, and washing elements are installed inside the body (RU 132327 U1, IPC A47L 1/08, publ. 09/20/2013).

A device for cleaning surfaces containing a cylindrical drive housing, inside which a hollow cylinder is rigidly fixed, connected to a washing fluid supply system and having grooves on the side facing the surface to be treated, cleaning working elements mounted on the housing in rows along the generatrix and valves communicating with grooves. The housing has holes made around the circumference. Each valve comprises a cup with a cover having an outlet, and a nozzle spring-loaded relative to the cover, coaxially mounted with the hole on the outer surface of the housing. The working end of the nozzle is placed in the hole, and the base passing through the hole is in contact with the outer surface of the cylinder. The hollow cylinder is mounted coaxially with the body, and each groove is located in an arc between two adjacent nozzles (SU 1440481 A1, IPC A46V 13/04, published on 11.30.1988).

A disadvantage of the known devices is the inability to use them to clean the outer walls of the tanks.

The objective of the claimed invention is to provide a device for cleaning the outer walls of the tanks.

The technical result is to ensure high-quality removal of contaminants from the outer walls of the tank, which allows to increase the life of the tanks by eliminating corrosion on the outer walls of the tanks.

The specified technical result is achieved, and the problem is solved due to the fact that the device for cleaning the walls of the tanks contains upper and lower longitudinal beams, a central beam located between them, connected at their ends by two transverse beams, at least one connecting strip located between the transverse beams and connecting the longitudinal and central beams, a coarse brush and a rubber brush fixed respectively to the upper and lower longitudinal beams and a felt brush attached to the central beam, two magnets fixed at the junction of the central beam with the transverse beams, washing supply system liquid, made with the possibility of supplying washing liquid in front of the rough brush and fixed on at least one connecting strip, transport rollers mounted on the transverse beams, while the device is made with the possibility of attachment to the lifting device to move it along the wall the cistern.

The lifting device can be performed, for example, in the form of a winch.

Magnets are neodymium magnets.

The detergent supply system may include detergent supply tubes, nozzles connected to the detergent supply tubes, a silicone hose connected to the detergent supply tubes and a high pressure pump connected to the silicone hose to connect the detergent supply system to a container with detergent and to a container with clean water.

Transport rollers can be made rubberized and spring loaded.

The claimed invention is illustrated by the following graphic materials: FIG. 1 is an external view of a device for cleaning the walls of tanks; FIG. 2 - diagram of the operation of the device for cleaning the walls of the tanks.

This device is a lightweight mobile structure that can move freely along the wall of the tank. The device is as follows.

Between the upper (8) and lower (12) longitudinal beams there is a central beam (9). The upper (8) and lower (12) longitudinal and central (9) beams are connected at their ends by transverse beams (10). At least one connecting strip (1) located between the transverse beams (10) connects the upper (8), lower (12) longitudinal and central (9) beams. The coarse brush (6) is fixed to the upper (8) longitudinal beam, and the rubber brush (7) is fixed to the lower (12) longitudinal beam, and the felt brush (5) to the central beam (9). Two magnets (2) are fixed at the junction of the central beam (9) with the upper (8) and lower (12) longitudinal beams, for example, by means of a bracket. The washing fluid supply system (4) is mounted on at least one connecting strip (1) with the possibility of supplying the washing fluid in front of the rough brush (6). Transport rollers (3) are fixed on the transverse beams (10).

The device is configured to be attached to a lifting device.

The claimed invention works as follows:

The device is driven by a portable lifting device, which can be used as a hand winch (16), which is fixed on the railing of the roof of the tank (Fig. 2).

When the device for cleaning the walls of the tanks (15) is lifted up the tank into the work area, a coarse brush (6) fixed to the upper (8) longitudinal beam is supplied with detergent from the detergent container, consisting of deoxyl diluted in an aqueous solution in the ratio of 1 :12.

Coarse brush (6) is used to remove dust and other fine dirt.

In the middle, on the central beam (9), a felt brush (5) is fixed, which cleans the walls of the tank with detergent. At this stage, chemical cleaning of the tank wall from rust deposits and other deposits.

A rubber brush (7) mounted on the lower longitudinal beam (12) after the felt brush (5) serves as a supporting detergent.

When the device for cleaning the walls of the tanks (15) reaches the top of the wall of the tank, the supply of detergent from the detergent container (14) is stopped, the supply system of the washing liquid (4) is rinsed with clean water from the tank with clean water (not shown), and the supply clean water does not stop until the device for cleaning the walls of the tanks (15) reaches the bottom of the tank wall.

When the device for cleaning the walls of the tanks (15) is lowered down, the rubber brush (7) drives away the remaining detergent. And clean water from the nozzles washes away the rest of the solution with dirt clean.

This process continues until the tank walls are completely cleaned. Each step of the passage of the device for cleaning the walls of the tanks is limited by its width.

The design of the device for cleaning the walls of the tanks allows simultaneously with the movement of the device for cleaning the walls of the tanks along the wall of the tank to supply the washing liquid with a high pressure pump to the supply system of the washing liquid from the tank with washing liquid installed from below in the tank of the tank through a silicone hose to the nozzles connected to tubes for supplying washing liquid.

When the device moves along the tank wall with three brushes, contamination is removed, which allows high-quality cleaning of the external walls of the tank.

To ensure that the device for cleaning the walls of the tanks does not come into contact with the wall, the distance between the wall of the tank and the device for cleaning the walls of the tank can be adjusted by making the transport rollers spring-loaded.

To avoid damage to the walls of the tank, the transport rollers can be rubberized.

The inventive device for cleaning the walls of the tanks, representing an autonomous means of cleaning, improves the quality of cleaning the outer walls of the tank, which eliminates the formation of undesirable corrosion processes on the walls of the tanks, which in turn provides an increase in the life of the tank.
