Description

one

The invention relates to the cleaning of the inner surface of pipes from various contaminants and can be used in the oil, gas and other industries of the industry.

A device for cleaning the inner surface of pipes is known, which comprises a working member made in the form of a metal brush connected to the impeller I. With Gzhel increasing the productivity of the device, the turbine is equipped with a conical cutter mounted on the common shaft with it and having guide vanes and n-and its front end strengthened screw head.

However, this device does not provide satisfactory cleaning of pipes from solid deposits.

The aim of the invention is to improve the quality of internal cleaning of pipes from solid deposits.

This is achieved by the fact that the device has cutters made in the form of hooked metal strips, one end of each of which is fixed pivotally on the shaft of the impeller.

The drawing shows the proposed device, the cut.

In the head 1 of the device, a housing 2 with a cover 3 of the impeller 4 is mounted, on the shaft 5 of which a disk 6 with brushes 7 and cutters 8 are fastened.

The brushes are attached to the disk in a loop x 12, and the cutters are mounted on hinges 13 directly on the impeller shaft.

The head and the shank are made of an elastic material, which ensures that the device fits snugly against the walls of the pipeline when passing along curved sections and is centered along the axis of the pipe.

The device works as follows.

Due to the central hole and close fit of the shank 11 and the head 1 to the pipeline walls, the flow of the pumped liquid is divided into two — motive and cleaning. Drive Stream Impact Shank Wall

moves the entire device through the pipeline in the direction of fluid flow. The obstacles to moving the device forward are contaminants in the pipeline.

The cleaning fluid flow, the passage through the central hole of the sleeve 10, rotates the impeller 4 and the disk 6 with the cleaning tool. Replacement cutters 8 loosen the deposits in the pipeline, and the brushes finally clean the walls of the pipeline from solid deposits.

Light ointments and similar deposits are washed off from the surface of the pipeline by streams of cleaning fluid flow passing through the cone-shaped holes in the disk and carried forward along the pipeline in front of the device. This ensures constant cleaning of the cleaning tools themselves from contamination and constant maintenance of them in working condition.

The brushes are additionally washed away from contamination by a part of the cleaning flow of fluid passing through the annular gap between the disk and the pipeline.
