Description

The invention relates to the cleaning of ycrpoiiCTiuiMH pipes, which are located along the pipes from the inside using pneumatic and hydratic drives, and can be used in energy and chemical industry, as well as in public utility and land reclamation.

The aim of the invention is to increase the cleaning efficiency by increasing the force effect of the deposition pa.

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a section of YYD in FIG. one.

A flowable working agent, for example water, flows from the hose through fitting 4 into the inside of the sleeve 14. Through the holes 16 water enters the spiral slots 15 5 and, passing through them to the heaters 3, causes the sleeve 14 to penetrate. As a result of the outflow of water through the nozzles 3, the device is stirred along the pipeline. If the sleeve 14 does not have a groove in the rear part, a union of yush, all the slots are 15, then the flow of water through the nozzles 3 occurs in a pulsed mode.

Vrashayupda with the sleeve 14 performs the role of the hydraulic distributor of the hydraulic drive.

The device for cleaning the inner side 15 communicates through the through slot 17 with the channel surface of the pipeline has a housing of 1.20, water enters the rear cavity of the hydraulic tailpiece 2 with jet nozzles 3 of the cylinder and moves the piston 7 forward, the front cavity of the hydraulic cylinder is connected by channels 21 and 22 with a groove 18 and further channel 23 - with the atmosphere.

These are means for moving the device along the pipeline, and fitting 4, which is a unit for connecting to the fluid supplying means, such as a hose. In the front part of the device there is a working op-1 an 5, which is a glass with cutting machines placed on its surface.

cylinder and moves the piston 7 forward, while the front cavity of the hydraulic cylinder is communicated by channels 21 and 22 with the groove 18 and then channel 23 with the atmosphere.

When the internal cavity of the sleeve 14 communicates through the through slot 17 with the channel 19, water through this channel and channel 21 enters the front cavity of the hydraulic cylinder, moving it backwards, while the rear poi scrapping elements 6. The working orifice of the hydraulic cylinder is communicated by channel 24 gan 5 placed on the housing 1 as an axle axle and associated with the rotation 7 of the hydraulic actuator of the reciprocating movement. The hydrocypal of the hydraulic actuator is formed by the skirt 8 of the body 1 and the skirt 9 of the handpiece 10, which is screwed onto the Cornus 1 in front. The cylinder is open in the middle, and the distance between the ends of the skirts 8 and 9 determines the course of the nozzle 7. The piston 7 is connected to the working body 5, for example, by bolts 11.

To ensure the piston 7 rotates

with a groove 18 and further channel 25 - with the atmosphere.

During the reciprocating movement of the norsch 7, the spiral groove 12 which is connected to it on the non-converging path 30 interacts with the gland 13, as a result of which the glitch 7 receives a reciprocating rotational movement around the longitudinal axis. Both of these movements are communicated with the piston 7 by bolts 11 to the working member.

around the longitudinal axis on the lateral surface, with the scraping elements located on it, the piston 5 is cut open by the cops o.

the spiral cap 12, and in the opening of the wall of the hydraulic cylinder (for example, in the skirt 8) there is an interconnecting spline 13 with a spiral groove.

On the side surface of the bottom 7, several spiral 40 unclosed grooves can be made, similar to the groove 12 and having a helix elevation angle. By selecting the appropriate groove, one can choose the most appropriate from technological considerations the angle of rotation of the working body around the longitudinal axis, as well as the torque value and speed of rotation associated with it.

To ensure reciprocating movement of the piston, the device is equipped with a spool valve and channels for the passage of the working unit. The slide valve hydraulics in the form of a sleeve 14 installed in the rear part of the housing 1 can rotate around the longitudinal axis of the sleeve 14 with spiral slots 15 on the outer side of the side surface of the bottom 7, several spiral 40 open grooves similar to the groove 12 and differing in helix angle can be made. By selecting the appropriate groove, one can choose the most appropriate from technological considerations the angle of rotation of the working body around the longitudinal axis, as well as the torque value and speed of rotation associated with it.

for the passage of water.

A device for cleaning the internal surface of the pipeline works as follows.

A fluid working agent, such as water, flows from the hose through fitting 4 into the inner part of sleeve 14. Through holes 16, water gets into the spiral slots 15 and, passing along them to Eople 3, causes sleeve 14 to penetrate. As a result of the outflow of water through the nozzles 3, the device is stirred along the pipeline. If the sleeve 14 does not have a groove in the rear part, a union of yush, all the slots are 15, then the flow of water through the nozzles 3 occurs in a pulsed mode.

Vrashayupda with the sleeve 14 performs the role of the hydraulic distributor of the hydraulic drive.

When the internal cavity of the sleeve 14

communicated through the through slot 17 with the channel 20, the water enters the rear cavity of the hydraulic cylinder and moves the piston 7 forward, while the front cavity of the hydraulic cylinder is communicated by channels 21 and 22 with the groove 18 and then channel 23 with the atmosphere.

When the internal cavity of the sleeve 14 communicates through the through slot 17 with the channel 19, water through this channel and channel 21 enters the front cavity of the hydraulic cylinder, moving it back, while the rear cavity of the hydraulic cylinder is communicated by channel 24

cylinder end is communicated by channel 24

with a groove 18 and further channel 25 - with the atmosphere.

In the reciprocating movement of the norm 7, the spiral groove 12, which is connected to it on the non-clamping one, interacts with the socket 13, as a result of which the defect 7 receives a reciprocating-rotational movement around the longitudinal axis. Both of these movements are communicated with the piston 7 by bolts 11 to the working member.

 with scraping elements on it, f.

On the side surface of the bottom 7, several spiral open grooves can be made, similar to the groove 12 and differing in the elevation angle of the helix. By selecting the appropriate groove, one can choose the most appropriate from technological considerations the angle of rotation of the working body around the longitudinal axis, as well as the torque value and speed of rotation associated with it.

The working body 5 can be made replaceable, and the scrubbing elements 6 can

The cylinder of reciprocating movement allows you to create significant effort to move the working body. This increases the impact of the scraper elements 6 on the sediments, thereby increasing the cleaning efficiency.
