BACKGROUND OF THE INVENTION The present invention relates to a pipe scrubber wire brush, which is a hydromechanical cleaning device for a deposit-contaminated pipeline, primarily for cleaning a pipeline for industrial and drinking water supply.

Hydraulic-driven (hydromechanical) pipe cleaning means are known from the patent applications HU 183 745 and HU 193 957 B.

A pipe knife holder with a knife and a plunger behind the knife holder are mounted on a pipe cleaning shaft of HU 183 745. It consists of knife-bearing segments which are fixed at one end of the shaft with a limited amount of rotation around the bolts. The blade holder segments are pre-tensioned by springs. At the other end of the shaft is a guide piston. This end of the shaft is connected by an articulated piston, preferably via a universal joint or resiliently. In particular, the operating piston and / or guide piston and / or shaft are provided with washing fluid guide holes.

The device is primarily recommended for removing hard, predominantly layered, carbonate-prone and other technological deposits.

A successful attempt was made to clean a 150 mm slag fly ash slurry, where the sediment was an aqueous mixture of flue gas. Cyclical cleaning removed sediment 2-3 mm / week. This appliance is primarily designed for cleaning industrial process lines, where it is possible to shut down and clean the cables for a longer period of time. The mechanics of the patented structure are not easily and simply manufactured, and their manufacture requires a great deal of skill to require precise fitting.

If this device gets stuck somewhere in the line, the line must be broken. In practice, these industrial pipelines and technological pipelines are built outdoors and flanged, so their disassembly and batch cleaning is not a problem.

The cleaning of drinking water deposits should only be stopped by the supply of drinking water for a few hours and therefore this tool and method is not applicable. In the case of a drinking water pipe, there is no way to open the pipe;

Patent application HU 193 957 relates to "means for cleaning the inside surface of a pipeline".

The essence of this is a cylindrical body with a hemispherical surface made of flexible foam material, the outer surface of which has an abrasion element fixed to the body. At least part of the abrasion element is a mesh made of steel chain links that are tucked into the body. In another embodiment, the net is partially disposed below the outer surface of the body. In a further embodiment, cutting elements are attached to the mesh.

Carefully manufacturing the device, making the mesh accurately, in particular, embedding it under the surface, providing it with a cutting element, and forming (molding) the flexible foam element is a labor-intensive, costly and complicated operation. Due to the cost-intensive nature of the device, cleaning with it is also expensive.

The present invention is intended to provide a device which

- cheap and effective mechanical tool,

- can follow the bends of the pipeline well,

- its application does not require any special skills,

- durable, abrasion resistant and easy to renew,

- hydraulically - water - movable but does not require high water consumption,

- it is simple to manufacture and easy to assemble from its components.

The object of the present invention is to provide a tubular scrubbing wire brush for the mechanical mechanical cleaning of the deposition on the inner surface of the pipeline by means of a flow of water, characterized in that its spherical cylindrical body comprises at least by inserting a spacer ring, the rear end of the slider is closed by a front closure, the individual elements being slidably formed.

The invention will now be described with reference to the exemplary embodiment shown in the accompanying drawings. The

Fig. 1 is a three-dimensional view of the pipe washer wire brush assembled, a

Figure 2 is a partially sectional view of the main elements of Figure 1, a

Fig. 3a is a side view, partly in section, and Fig. 3b is a back view, partially in section, of the wire brush.

The pipe washer wire brush comprises a sleeve core 1 with a flexible, at the top resilient closure 3 under which six wire brush discs 2 containing knotted wire bundles are threaded. The wire harnesses extend radially in a brushed arrangement, the ends of the elementary wire strands defining a hollow cylindrical shell having a diameter D6 (see Figure 3a) corresponding to the inside diameter of the pipeline to be cleaned. Below the bottom 2 wire brush discs there are 4 sliding blades having a diameter D2 smaller than the diameter D6, preferably having a thickness L3 of at least 7-8 mm.

The flexible sleeve core 1 may be formed from a single piece, or from a thin diameter disk D4 mounted on a thin core D7 diameter or spacer rings 5. Figures 2 and 3a, 3b show that the diameter D4 is approx. 1/3 of the D6 diameter.

The flexible sleeve core 1 with the sliding plate 4, the spacer ring 5 and the closure 3 may preferably be made of a solid technical rubber based on fluorocarbon, having a Shore hardness of 60 ± 5 A. This ensures the flexibility of the cleaning agent.

The wire brush discs 2 of Figures 3a and 3b are made of a rigid material, the knotted wire bundles being threaded into it along the mantle. The individual elements can be slid onto one another, the stub 3a of the closure 3 fits snugly into the sleeve core 1.

The function of the fastening elements 3 is primarily the final fixing after the assembling of the individual elements.

The cleaning tool consists of at least six 2 wire brush discs. The length of the assembled pipe washer wire brush shall be at least one and a half times the nominal diameter of the pipe, so that it cannot cross the pipe.

HU 213 692

It may be advantageous to increase the thickness of the wire strands of the successive wire brush discs 2 in the direction of the slide blade 4.

It is not shown in the drawing that one or more sponges of the desired softness can be placed after the sliding blade 4, the function of which is to prevent the escape of water pushing pressure and to remove loosened dirt when cleaning a long pipe section.

The technical rubber elements of the pipe washer wire brush can be made in a baking tool and can be renewed in case of wear.

They are easy to assemble.

The pipeline is cleaned by the wire ends of the spherical roll shell, and the device is advanced by the pressure of the water flowing into the pipeline and acting on the slider 4.

Worn wire fibers can be reattached in the 2 wire brush discs.

Due to its construction, the pipe washer wire brush follows well the bends of the pipe, reliably removes stubborn deposits on the pipe wall and does not damage the inner wall of the pipe.

The ideal length of pipe to be cleaned is 500-700 m.

When applied, the cleaned pipe diameter range is NA 80-200 mm.

It is effective for single pipe cleaning and can save significant amounts of water.

The pipe washer wire brush can be inserted into the pipeline through existing fittings such as a gate valve, for example with a device specially designed for this purpose. At the end of the cleaned pipe section, remove the cleaning device arriving at the drain connection or at the place of a disassembled pipe fitting.
