DD205475A1 - COMBINED MECHANICAL PIPE CLEANING UNIT WITH BUILT-IN HIGH PRESSURE COOL HEAD - Google Patents

Abstract

The combined mechanical pipe cleaning device with built - in high - pressure spool head is used for the cleaning of free - fill sewer pipes in the field of construction / water management. The aim of the invention is to set by the deposition of solids unusable become pipelines again in motion and thereby avoid new construction of lines. A combination of mechanical hydraulic construction part for the solution and removal of solid deposits in Entwaesserungsrohr with additional part for cutting roots represents the essence of the invention.

Title of the invention

Combined a mechaniaehea pipe cleaning device with built-in high pressure appr

Field of application of the invention

The invention relates to the elimination of deposits and roots in Entwäaaerungleitungen.

Characteristic of the known technical solution

Three methods are known;

- mechanical cleaning,

The device in the form of a brush or a Wurzelachneidera is pulled by a winch through daa tube, Mitteli'eate deposit aie cut roots are pulled with the device to the next slot and eliminated there.

- Cleaning by means of a high-pressure dishwasher.

Daa high-pressure washing machine works with Reinwaaaer, as it is returned to a rinsing head by a container vehicle under extremely high pressure via a hose line. Ea occurs. There, axially behind, and drive the flushing head with the pressure balance hose through the drainage line. Slight deposits and muddy congestions are slurried and slurried to the next shaft, slurried by flowing waaaera, and disposed of there.

Cleaning by means of Spülachwall

the drainage line allows the damming up of sluices only for cleaning in the shafts, and is released again by a hand-pull on the SpUlachwall. Deposits are removed at the next lower shaft.

The abovementioned three methods do not permit the removal of solid or crystalline deposits or blockages.

In the mechanical process, the brushes are pressed together in the deposition area and go over it. The wort trimmer initially loosens the solid deposits, but then jams in conjunction with these and the remaining solid deposits.

Hydraulic release by means of high-pressure coupling or accumulation is not possible.

The known technical solutions are mainly in the book "wastewater treatment" by Dr. med. RandοIf, BA of the GDR, called.

Object of the invention

The purpose of the invention is to eliminate solid to crystalline deposits and roots in drainage lines.

Explanation of the essence of the invention

Erfindagemäß the object is achieved in that a Hydraulikiesches is coupled with a mechanical cleaning device. A diameter dea dea to be cleaned Rohrea adapted hollow cylinder steel with loosening and Wurzelachneid tines is axially provided in the middle piercing piece with a high pressure rinsing.

The rinsing head is interchangeable and is screwed by means of a threading on an also axial pipe piece. This piece of pipe is fastened with three struts on the hollow cylinder. A pressure hose is threaded on the anaer side of the pipe section. Drawbar eyes are arranged axially on both sides and three

Aeitig braced welded in Hauptzugrichtung on Rohratiick the pipe section.

The Düaen this flushing head are arranged perpendicular to the pipe wall.

The water jets emerging from the nozzles under high pressure crush the deposits loosened by the mechanical part, sludge them up and flush them out of the pipe.

At the same time, the W asaera eaves clean the inner wall of the drainage pipe. The Düsendurhmesser the replaceable Spiilkop'fes is variable. This achieves the effective rinsing water pressure.

The D Us enaustrit ta angle can be tilted in main direction of the cleaner by replacing the Splilkopfes, ie I ¹ I ießrichtung the waste water.

This creates a stream of water in front of the device in the area of the loosening tines, which causes an immediate discharge of the gelokcerten, aufschwämmten deposit.

The device is pulled from shaft to shaft via two winches, with one winch being installed as a hose winch on a high-pressure flushing unit. The winch cables are connected to the drawbar eyes of the device.
