Description

The utility model relates to means for cleaning the walls of containers from oil products and the contaminants that are present, and can be used, in particular, for cleaning tank wagons from frozen dark oil products.

A device is known comprising a hollow rod with transverse bends on which nozzles are fixed. The rod is mounted in the opening of the tank by means of a ball bearing. The cleaning agent is supplied under pressure to the surface being cleaned through the hollow rod, taps and nozzles located perpendicular to the taps and the hollow rod. The jets of oil, flowing out under pressure from the nozzles, rotate the rod along with the bends. The shoulders of the taps are made unequal (patent 2200067, IPC B08B 9/09, 09/09/2001) - prototype.

The specified device is not effective enough:

 by coverage of the surface being cleaned;

 by the quality of cleaning (expressed in the need for manual washings of unwashed traces of oil products);

 on energy efficiency, due to the costs of fuel and energy resources (fuel and energy resources, in particular, on heating the required amount (volume) of hot water and exposure time (the shorter it is, the less downtime the tank car);

 in terms of universality and ergonomics - reduction in the number of operations by personnel, determined by the number of preparation operations carried out without rearranging the washing installation (optimally, all operations {steaming, blurring excess residue, washing, drying / degassing} are performed without changing the washing installation).

The closest analogue of the claimed device is a technical solution known from SU 1834720, IPC B08B9 / 08 08/15/1993. The known washing installation comprises a support disk, sliding rods located at an extended angle with washing heads mounted on them, an exhaust pipe, the extension point of the rods being close to the supporting disk, and the free ends of the extension rods equipped with extensions.

A disadvantage of the known design is the lack of coverage of the washed surface.

The technical result from the use of the proposed technical solution can be expressed in increasing the efficiency of cleaning containers from oil product residues:

by increasing the coverage area of the washed surface (including the absence or minimizing of unwashed "dead" zones) by expanding the sliding rods to an undeveloped angle (angle less than 180 ⁰ );

 by minimizing fuel and energy resources (FER) to achieve a result;

 by reducing exposure time;

 by reducing the number of installations of washing equipment;

 due to ergonomics (thoughtfulness / ease of use) that minimizes the maximum required effort of the operator, the number of operations performed, ease of control when they are performed;

 due to the ability to supply detergent under high pressure, about 100 bar.

The claimed technical result is achieved as follows.

A universal washing installation for preparing tank wagons for loading oil products, containing a support disk with channels, an exhaust pipe mounted on it, located in a vertical plane on which sliding rods are installed, located in a folded position along the exhaust pipe, made with the possibility of their dilution relative to the place installations with the formation of an undeveloped angle between them, the sliding rods are equipped with washing heads located at their free ends. At the same time, the installation location of the sliding rods on the exhaust pipe is as close as possible to the support hatch, at the same time, preventing contact with it.

Sliding rods are equipped with telescopic or removable extensions.

one of the channels of the reference disk is made in the form of a steam channel with one or more steam nozzles.

Also, one of the channels of the support disk can be made in the form of a channel for supplying and removing air (supplying and pumping out a gas-air medium for drying and degassing).

Also, one of the channels of the supporting disk can be made in the form of a channel with a valve for filling the boiler with hot water to heat the excess oil residue in the cold season.

Also, one of the channels of the support disk can be made in the form of a channel for pumping out the remaining product and / or drain by vacuum.

The claimed utility model is characterized by the following illustrations.

In FIG. 1 shows a sliding washing installation in a working position;

In FIG. 2 shows a sliding washing installation in a folded position;

In FIG. 3 shows a support disk, a top view;

Fig. 4 shows a sliding washing installation located inside the railway tank car.

A universal washing installation for cleaning tank wagons of oil product deposits contains a support disk 1, sliding rods 2 with washing heads 3 mounted on them and an exhaust pipe 4. The extension point of the rods is as close as possible to the support hatch 1. And the free ends of the extension rods can be equipped with extension cords 5.

Extenders 5 of the sliding rods 2 can be made telescopic or removable.

At the same time, the washing unit is equipped with a steam channel 6.

Also, the support disk can be equipped with a device for connecting 7 and means for supplying air 8.

The support disk can optionally be equipped with a rod position sensor that determines the optimal position for starting preparation operations.

During operation, the washing installation is located on the upper surface of the loading hatch of the tank. The exhaust pipe 4 translates the installation into a folded (Fig. 2) or working (Fig. 1, 4) position. In the folded position, the exhaust pipe 4 is shifted down and mounted on the support hatch 1, and the washing heads 3 are turned down. In this position, the washing unit is lowered into the tank. In the working position, the support disk 1 is tightly located on the neck of the tank. The exhaust pipe 4 is retracted by the lifting device to the extreme position, while the sliding rods 2 with extended extensions 5 are maximally spread apart.

The safety sensor generates a “device ready for operation” signal.

Steam can be supplied through the steam nozzles for steaming the tank. On the supporting disk 1 there are devices for connecting 7 to the dry warm air supply lines. The nozzles of the washing heads 3 rotate in two planes, and thus cover the entire inner surface of the tank. The presence of 2 washing heads diluted over a considerable distance (about 3 m) makes it possible not to leave unwashed areas (“dead zones”) caused by shielding by the internal equipment of the boiler: a ladder and a stem for opening the lower drain valve. The drive is carried out by the supplied fluid. After cleaning, air can be drawn in / out through warm air connection devices to dry and degass the tank.

The proposed utility model allows you to:

 significantly increase the cleaned area of the internal surfaces of railway tank cars, including from solid residues of dark oil products.

 to improve the quality of cleaning (no need for manual re-washing of unwashed traces of oil products)

 increase energy efficiency (significantly reduce the costs of fuel and energy resources) and exposure time (downtime of a tank car);

 increase universality and ergonomics (reduce the number of operations for personnel - all preparation operations are carried out without changing the universal washing installation).
