Description

O) 00 Oi N5

The invention relates to the cleaning of the external surfaces of pipes from deposits, such as slag or ash, and can be applied to repair plants and other areas where the treatment of pipe surfaces is required.

The purpose of the invention is to increase cleaning performance and expand technological capabilities.

FIG. 1 shows a device, a longitudinal section; in fig. 2 - the same, top view; in fig. 3 - the same plan view; in fig. 4 shows section A-A in FIG. 3

The device contains a cylindrical metal body 1 that is detachable along the longitudinal axis and encompasses pipe 2.. The housing 1 has end caps: the upper 3 and the lower 4 with the groove for the pipe 2. Inside the housing 1 there is a detachable cup 5 of material with a low coefficient of friction, such as bronze. Inside body 1 in col 10

The rotor 6 cleaning elements 8, located along a helical line, promote (due to the force of friction and jet reaction) the device along the pipe 2, simultaneously clearing the slag-formation an, while the working fluid, having passed the blades 7, flows through the nozzle holes 18 to the walls of the pipe 2 wetted overlying layers of slag. The slag accumulated during the cleaning process is removed with the flow of working fluid through the windows in the cleaning element 8 and the annular gap in the lower cap 4 and the shock absorber 19. As a working fluid, besides ordinary cold or heated water, a special composition of slag-forming components can be used by chemical means. When the tube plate 22 is reached, the stop 15 shrinks the sponge clip 14 from the housing 1. In this case, the spacer rings 13 release the connection between the halves of the housing 1, the cup 5 and the rotor 6 in the merge of the slotted grooves of the covers 3 and 4 are fitted disconnecting On returning the device, the rotor 6, on the outer surface to its original position, under its own, are screw blades 7 with a T-shaped shank, and cleaning elements 8 (Fig. 2), for example, metal brushes . In the annular grooves of the lids 3 and 4, supporting sleeves 9, for example bronze, are installed, which are the bearings for the Ro-device for cleaning the outer surface 6. The upper 3 and lower 4 contents of the vertical tubes contain 10 central cylindrical body with face

by weight. Next, the cleaning cycle is repeated. To eliminate the twisting of the device relative to the pipe 2, spacers 20 having rollers 21 serve.

Claims (1)

Invention Formula with nuts 11 and springs 12. Spacing rings 13, installed inside housing 1, sponge clamp 14 with stop 15 and hinge 16. For supplying the working fluid serve as a connector for the device along the longitudinal axis. covers to cover the pipe being cleaned, made split in the axial plane and having a clip for connecting its parts along the line of the connector, a fitting for supplying liquid inside the body and channels for 40 for example, water, to the blade 7 of the rotor 6 in the lower fluid, the cleaning elements, located on the cover 4, has a fitting 17, and for the inside of the housing and the blade drive, the liquid stroke in the upper cover 3 are nozzle openings 18. On The bottom cover 4 has a rubber damper 19. Spring-loaded spacers 20 with rollers 21 (FIGS. 3 and 4) are rigidly attached to the lateral outer walls of the housing 1, supported by pipes adjacent to the pipe being cleaned, assembled into a tube bundle embedded in tube boards 22 . The device operates as follows, with its ends in its lids by means of a cleaning device prior to cleaning, and an emphasis to open the clamp when in contact with the upper tube plate, while the cleaning elements and drive blades are mounted respectively on the outer and inner surfaces , in order to increase the cleaning performance and expand technological capabilities, it is equipped with rigidly connected to the body and located inside the axial plane detachable Kan with detachable ring gaskets at its ends, a detachable cylindrical hollow rotor mounted inside the housing and fixed along the connector line, is mounted around the pipe 2 and clamped with a sponge clip 14 (Fig. 2). The pressurized working fluid is supplied through fitting 17 (Fig. 1 on the working blades 7 of the rotor 6. With a turn-50 P ° helix. 0 The rotor 6 cleaning elements 8, located along a helical line, promote (due to the force of friction and jet reaction) the device along the pipe 2, simultaneously clearing the slag-formation an, while the working fluid, having passed the blades 7, flows through the nozzle holes 18 to the walls of the pipe 2 wetted overlying layers of slag. The slag accumulated during the cleaning process is removed with the flow of working fluid through the windows in the cleaning element 8 and the annular gap in the lower cap 4 and the shock absorber 19. As a working fluid, besides ordinary cold or heated water, a special composition of slag-forming components can be used by chemical means. When the tube plate 22 is reached, the stop 15 shrinks the sponge clip 14 from the housing 1. In this case, the spacer rings 13 release the connection between the halves of the housing 1, the cup 5 and the rotor 6 in the measure of the connector, which leads to the return of the device to its original position. for cleaning the outside of the top 20, which leads to the return of the device to its original position under its own by weight. Next, the cleaning cycle is repeated. To eliminate the twisting of the device relative to the pipe 2, spacers 20 having rollers 21 serve. Invention Formula vertical pipes containing a cylindrical body with end covers to cover the pipe being cleaned, made split in the axial plane and having a clip for connecting its parts along the line of the connector, a fitting for supplying liquid inside the body and channels for liquids, cleaning elements located inside the casing and paddle drive, liquids, cleaning elements located inside the casing and paddle drive, its ends in its lids by means of detachable liners, and an emphasis to open the clamp when in contact with the upper tube plate, while the cleaning elements and drive blades are mounted on the outer and inner surfaces, respectively, in order to improve cleaning performance and expand technological capabilities , it is equipped with a cup rigidly connected with the body and located inside it, split in the axial plane with split ring gaskets on its ends, detachable cylindrical hollow rotor mounted inside the case and fixed 18 3 and nasts / f (4g.2 W Pat) f7ifaj uo vocmi srigL (.posti riMi) V.
