RU2182528C2 - Apparatus for cleaning inner surface of tubes - Google Patents

Abstract

FIELD: exploitation of water conduit and sewerage in municipal engineering, industrial plants and building. SUBSTANCE: apparatus includes housing with inflated envelope inside it. Said envelope is inflated at cleaning tube and it is released when apparatus is introduced or removed. Inflated envelope pushes apart housing; at changing pressure inside envelope it is possible to adjust pressure effort of working organs on tube surface. Housing with working organs secured to it is in the form of flexible durable envelope; inflated envelope is flexible, non-stretched and it has fluid-tight coating. EFFECT: improved design. 1 dwg

Description

 The invention relates to technical means for cleaning the inner surface of pipelines from pollution and can be used in the operation of the water supply and sewage systems in public utilities and industrial enterprises.

 A device for cleaning the inner surface of the pipeline, comprising a housing and a sealing chamber of a toroidal shape made of flexible material, filled with fluid and installed in a lodgement on the side surface of the housing, see ed. St. 1261727, cl. 08 V 9/04, published. 10/07/1986.

 The disadvantage of this device is the inability to use the device without high fluid costs, the movement of the device in only one direction, the likelihood of a device getting stuck when the pipe diameter changes, during bends or when there is a lot of dirt, the inability to replace the scrapers and use other working bodies.

 A device for cleaning the inner surface of pipes is known, comprising an outer shell of rigid material with holes, an elastic elastic body enclosed in this shell, and cleaning elements installed in the holes, the bases of which are located between the outer shell and the elastic elastic body. The elastic body is made hollow, and the device is equipped with a pipeline for supplying pressure medium to the cavity of the medium, while on the outer shell slots are made in the form of a multi-start spiral, coaxial pipeline, see author. St. 1348015, cl. 08 V 9/04, published. 10/30/1987.

 The disadvantage of this device is the ability to operate the device only on flat sections of the pipe due to very small possible changes in the diameter of the outer shell of the hard material, therefore, the scope of application of this device is limited and the quality of cleaning is not high, and the elastic shell can exit into the slots of the outer shell and its damage, which leads to a breakdown of the device, therefore, the device is unreliable.

 The proposed device aims to improve the quality of pipe cleaning from contamination, reduce the specific gravity of the device with increasing diameter of the pipes to be cleaned, speed up, simplify and facilitate the operation of the device when it is inserted into the pipe to be cleaned and removed from it, to make the device work in any direction, the possibility of replacement and the use of any working bodies, to eliminate the likelihood of a stuck device when changing the diameter of the pipe, during bends and with large contaminants.

 This problem in this invention is solved due to the fact that in the device for cleaning the inner surface of the pipes containing the housing, the pumpable shell placed inside it, the housing with the working bodies attached to it is a flexible durable shell, the pumped shell is flexible, inextensible, with a sealing coating, is compressed with an increase in the pressure force of the scrapers, it also descends when the device is inserted and removed. This makes it easy to insert and remove the device from the pipe, and also prevents the device from getting stuck when turning the pipe, when changing the diameter of the pipe and with large contaminants. The pumped-up casing is pumped up during the cleaning of the pipe and bursts the casing, changing the pressure in it, it is possible to adjust the pressure force of the scrapers on the pipe surface, thereby improving the quality of cleaning the inner surface of the pipes. To pull the device through the pipe, a cable is used, fastened in front and behind a flexible shell.

 The proposed device is illustrated using the attached drawing, which shows a General view of the device.

 A device for cleaning the inner surface of the pipe contains a housing 1 with working bodies 5. Housing 1 is a flexible, durable shell. Inside it is an inflated shell 3, which is inflated during pipe cleaning and descends when the device is inserted and removed. The camera 3 bursts into the housing 1 and, changing the pressure in it, you can adjust the pressure force of the scrapers 2 on the surface of the pipe.

 An example of a specific implementation of the device. The case is made of a braided steel cable with a diameter of 5 mm with a mesh size of 40x40 mm. The inner shell is made of rubberized fabric with a thickness of 5 mm. The working bodies are knives mounted on cable cells at an angle to the surface of the device.
