Description

The utility model relates to the field of cleaning of technical objects and is intended for steaming (washing) cleaning devices from piston products of main condensate pipelines, with the possibility of transporting them from piston launching and receiving units on the linear part of pipelines to the place of revision and storage.

A device for steaming cleaning devices [Patent RU No. 126268, IPC B08V 3/02, publ. March 27, 2013], containing a cylindrical chamber with two end caps for sealing the chamber and means for supplying a coolant to the chamber, while the chamber is installed on a support structure, on which means are also installed for stocking cleaning devices into the chamber, and under the chamber there is a container for collection of water-oil emulsion, wherein the collector for supplying the coolant is located on the outer periphery of the chamber, and is connected to nozzles installed with the possibility of supplying and evenly distributing steam throughout the volume of the chamber.

The disadvantage of the known device is that the cleaning device inside the chamber is stationary in relation to the nozzles, which does not provide high-quality processing of the entire surface of the cleaned device.

Known mobile installation for steaming cleaning in-line devices [Patent RU No. 173821, IPC B08V 3/02, publ. 09/13/2017], containing a cylindrical chamber mounted on a supporting structure with nozzles that are connected to a manifold placed on the chamber for supplying steam, while the chamber consists of a base and a top cover, while the nozzles are installed in the upper part of the chamber cover, the manifold for supplying the steam is placed on the outer surface of the chamber cover, a frame for accommodating the in-line device is installed inside the chamber base, made with the possibility of circular rotation, in addition, a drain pipe is installed in the lower part of the chamber base for connection with a tank for collecting water-oil emulsion.

The disadvantage of this installation is that the work is carried out inside the building by service workers manually using respiratory protection equipment, a special tool that excludes sparking, since paraffins and oil products are on the OS surface that can ignite and poison workers. In addition, for washing different diameters of the OS, it is necessary to replace it on the frame with the help of bolted connections for a certain size of the flange fastening, and the replacement of nozzles is not provided.

The technical result is to ensure safe working conditions with a simultaneous increase in productivity, exclusion of environmental pollution, ease of operation of the container, versatility with the possibility of washing four types of cleaning devices (DN 300, 350,500,700) in one container.

The technical result is achieved due to the fact that the container for steaming the cleaning devices of the pipeline includes a housing mounted on a support with a lid, on the inner sides of which there are attachment points for the cleaning device, made with the possibility of ensuring its rotational movement; a manifold with steam supply nozzles is mounted along the length of the container, and the attachment assembly for the head part of the cleaning device consists of a faceplate, a shaft with a bearing assembly and a scroll handle, and the opposite attachment assembly includes a clamping spindle, a flywheel, a spindle rotation locking lever, on which a conical locking device is mounted ; a pipe is mounted in the lower part of the body. Moreover, a branch pipe with a safety valve is embedded in the upper part of the body.

The figure shows the container in section.

Container for steaming pipeline cleaning devices includes:

- housing 1, which is a welded structure of the housing (1), consisting of a shell (pipe 1020×10 mm, length 1600 mm) and two flat bottoms (sheet ∅1020×10 mm.);

- cover 2, a cover fixed on the body with two hinges (a fragment of a pipe 1020 × 10 mm) with a size of 1300 × 800 mm;

- support 3, which is two support posts made of pipes ∅76×4 mm, on which the body 1 is installed;

- attachment points of the cleaning device (OD) located on the inner sides of the housing 1;

- collector 4 with nozzles 5. Sixteen nozzles 5 with holes ∅4 mm are fixed on fittings 6 of collector 4 by threaded connections (it is possible to replace the nozzle without welding). The collector 4 in the outer part is equipped with a quick coupling element (BRS) 17 for connection with the pipeline main control unit.

The attachment assembly of the head part of the cleaning device consists of a faceplate 7, a shaft 8 with a bearing assembly (for easy rotation of the OS) and a scroll handle 9.

The opposite fastening unit (yoke unit) includes a clamping spindle 10, a flywheel 11, a lever 12 for blocking the rotation of the spindle 10, on which a conical locking device 13 is mounted, which can be installed with a cleaning device tracking signaling device.

In the lower part of the body 1, a branch pipe 14 with a 90° outlet is mounted with the possibility of attaching a pressure rubberized sleeve 18.

Moreover, in the upper part of the body 1, a branch pipe 15 DN 100 with a safety valve 16 of the membrane type is embedded (to relieve excess steam pressure from the container). In the event of an increase in pressure in the container, the membrane breaks and the steam through the pipe 15 and the valve 16 escapes into the atmosphere.

The operation of the container for steaming cleaning devices is carried out as follows.

The container is installed on a prepared site next to the drainage tank. The lid 2 of the container 1 is moved to the "open" position. The operability of the attachment points and rotation of the cleaning device in the container is checked, visually the state of the steam supply nozzles 5 is checked. Slinging of the OS previously cleaned mechanically is carried out, while the axis of the OS must be horizontal. The OS is fed into the container and the head part of the base is fixed on the faceplate 7. A conical locking device 13 is inserted into the base hole at the place where the tracking signaling device is attached and installed on the groove of the spindle 10. By rotating the flywheel 11 and holding the lever 12 to block the rotation of the spindle 10, the OS is pressed against the faceplate 7 and fixation on the conical fixing device 13. The lid 2 of the container is brought to the "closed" position. The pressure rubberized sleeve 18, attached to the branch pipe 14, is fixed to the neck of the drainage tank (not shown in the figure).

Next, the installation of a steam collection pipeline from a mobile steam plant (SPU) located on the basis of a Kamaz 43118 vehicle is carried out. The pipeline from the SPU to the container is fastened with a quick-release joint 17. The SPU is located outside the site at a distance of at least 15 meters. The supply of heated steam at a temperature of 140-180°C is made into the collector 4 and through sixteen nozzles 5 (nozzles), the steam enters the cleaning device and washes off the pollution. After 10-15 minutes, the operator rotates the OS in the container using the scroll knob 9. During the entire steaming time (30-40 minutes), the operator from the side monitors the removal of contaminants into the drainage, the absence of third parties in the working area. The DU is removed from the container in the reverse order after the container and DU are completely cooled down (T<30°C), and if necessary, the DU in the container is delivered to the base without environmental pollution.

For some types of cuffs of cleaning devices (for example, foreign-made flaw detectors are equipped with cuffs with a use temperature of up to 100 ° C), exposure to high temperatures is prohibited according to the technical specifications (cuffs become brittle and are not allowed for reuse), the use of steam is prohibited. The developed container can be used without making structural changes for washing the OS (only nozzles 5 are replaced), with hot water at a temperature of 80-90°C, with surfactants under pressure with a heated water washer "KARCHER HDS-797".
