Изобретение относитс к машиностроению , в частности к устройствам дл очистки внутренних поверхностей трубопроводов от отложений и загр знений, и может быть использовано в газовой, нефт ной, молочной и пищевой промышленности.The invention relates to mechanical engineering, in particular to devices for cleaning the internal surfaces of pipelines from deposits and contaminants, and can be used in the gas, oil, dairy and food industries.

Известно устройство дл очистки внутренних поверхностей трубопроводов, включающее полый корпус с отверсти ми дл подачи рабочей жидкости в зону обработки, св занную с ним лопастную турбинку с закрепленными на наружном диаметре лопаток щетками 1.A device is known for cleaning the internal surfaces of pipelines, comprising a hollow body with openings for supplying the working fluid to the treatment area, a vane impeller associated with it with brushes 1 fixed to the outer diameter of the blades.

Недостатком этого устройства вл етс невозможность ополаскивани трубопровода в момент работы всего устройства в полости трубопровода, что значительно ухудщает качество внутренних поверхностей трубопроводов , так как в зоне очистки остаетс продукт износа ворса, щеток и частицы загр знений, удаление которых из зоны очистки потоком моющей жидкости невозможно. Цель изобретени - повышение эффективности очистки. A disadvantage of this device is the impossibility of rinsing the pipeline during operation of the entire device in the cavity of the pipeline, which significantly degrades the quality of the internal surfaces of the pipelines, as the wear product of the pile, brushes and dirt particles remain in the cleaning zone, which cannot be removed from the cleaning zone . The purpose of the invention is to increase the cleaning efficiency.

, Поставленна цель достигаетс тем, что в устройстве, содержащем полый корпус с отверсти ми дл подачи рабочей жидкостиThis goal is achieved by the fact that in the device containing a hollow body with openings for supplying the working fluid

в зону обработки, св занную с ним лопастную турбинку с закрепленными на наружном диаметре лопаток щетками, каждый ворсовой элемент щеток имеет полую вставку из упругого материала и выполнен со сквозным каналом, имеющим косой срез в выходном сечении.In the treatment area, the impeller impeller associated with it with brushes attached to the outer diameter of the blades, each pile element of the brushes has a hollow insert of elastic material and is made with a through channel having an oblique section in the output section.

Устройство состоит из полого корпуса 1, с двум р дами радиально расположенных отверстий, на который навернута штанга 2 дл подвода моющей жидкости, и на ци 1индричеекой части которого установленаThe device consists of a hollow body 1, with two rows of radially arranged apertures, on which a rod 2 is screwed to supply washing liquid, and on the center of which the core of which is installed

15 турбина 3, наружный диаметр лопаток оснащен щетками 4, ворсовой элемент которых выполнен со сквозными продольными каналами дл подачи моющей жидкости в зону очистки, а выходное сечение выпол2 нено с косым срезом под углом л, где 0° Л -90°. Каждый ворсовой элемент имеет полую вставку из упругого материала.15 turbine 3, the outer diameter of the blades is equipped with brushes 4, the pile element of which is made with through longitudinal channels for supplying washing liquid to the cleaning zone, and the output section is made with an oblique cut at an angle l, where 0 ° L -90 °. Each pile element has a hollow insert of elastic material.

Claims

A hub 5 is installed on the casing with spring-loaded racks 6, on which the rollers 7 are located on the axles. The horizontal movement of the impeller and the hub is limited by two stop rings 8. On the case of the impeller there is an annular groove and through channels for supplying washing liquid to the hollow pile of the brushes. Pile brushes of variable stiffness in length. The device works as follows. The device on the rollers is introduced into the cavity of the flushing pipeline to be cleaned, and the movement is informed to it. A washing liquid is supplied through the boom under pressure. The liquid jet through the radial holes presses on the impeller blades, driving the latter into rotation. To the hollow pile of brushes and further to the washing zone, liquid is supplied through the second row of radial holes, an annular groove and through holes in the impeller body. The impeller, rotating, touches the brushes of the surface being cleaned on it with simultaneous exposure of the washing liquid to it, which enters the treatment area through the through longitudinal channels of the pile. After the surface is sufficiently cleaned, the pressure of the liquid is increased, the pile of brushes due to the normal component of the reactive force of the ejected jets, provided by the angular position of the output channel, is deflected over the flexible section and out of contact with the surface. The cleaning zone is flushed away by the rotating jets and the stream of washing liquid carries away the dirt particles and the worn product of the brushes from the treatment zone. If the cleaned surface does not meet the requirements, the liquid head is reduced, and the cleaning process is repeated. The proposed device makes it possible to combine mechanical action on the particles of contaminants with simultaneous supply of the washing agent to the treatment area, followed by rinsing of the cleaned area, which leads to an increase in labor productivity by a factor of 1.5–2. Apparatus of the Invention A device for cleaning the inner surface of pipes, comprising a hollow body with openings for supplying the working fluid to the treatment area, an impeller impeller associated with it with brushes attached to the outer diameter of the barrel, in order to increase the cleaning efficiency, Each pile element of the brushes has a hollow insert of elastic material and is made with a through channel having an oblique cut in the output section.
