DE4003635C1 - Sanitation pipe cleaner - flushes liq. from refillable container via flushing pipe, and air via compressed air pipe - Google Patents

Abstract

A transportable device for the removal of sediments and other obstructions in sanitation pipes uses flushing liq. and compressed air and forms a sealed system. The flushing liq. (2), which is hot or cold water or chemical agent, is in the refillable container (3) which has an outlet (13) valve or stop cock at the base. The riser pipe (4) carriers the flushing liq. to the connector (5) and to the flushing pipe (6) which is inserted into the sanitation pipe (1) and quick fit union pipe junctions are used for these joints. Compressed air is introduced to the connector by a compressed air pipe (7) and into the container by way of compressed air pipe (8). A hand operated shut off valve (9) is located between the connector (5) on the compressed air pipe and comprises a hand lever with stop cock. The compressed air pipe carries a tee piece (10) with a manometer (11) from which the other compressed air pipe leads to the neck (3A) of the container. Compressed air pipe has a shut off valve or stop cock (23). The riser pipe and compressed air pipe are fitted through a removable lid (21) of the container and may be screwed or inserted through the lid. These fittings are removable. The manifold (19) before the manometer has pressure regulator (18). Isolating valve (17), a non return valve (16) and tee fitting (15) with pressure release point (15A). And has a quick fit union pipe joint (14) at its end.

Description

The invention relates to a transportable Device with which sanitary pipelines by means Compressed air and flushing fluid from deposits and Blockages can be cleaned.

Such a device is known from DE-OS 16 58 175 known. For cleaning all or part clogged drain lines there is the front of the Clogged water column due to rapid Opening a shut-off device in a compressed air Hose line pressurized with compressed air. Here so-called shock waves arise, which cause constipation remove. The rinsing liquid is at one Water tap removed. An adjustment of the pressure of the Rinsing liquid to different deposits and Blockages are not intended.

The object underlying the invention is that the device according to claim 1 regardless of  a water tap and its line pressure also strong adhering deposits and persistent blockages in is able to eliminate in a short time.

This object is achieved by the characterizing Features of claim 1 solved, the still in the individual subclaims Design features of advantageous developments of Represent task solution.

The pipe cleaning device according to the invention is as compact and easily transportable handheld device and has a container that can be filled with rinsing liquid, via a riser pipe to the pipeline to be cleaned can be connected and its rinsing liquid by compressed air is pressed out of the container into the pipeline.

The flushing liquid therefore flows into the pipe to be cleaned and in addition to increase of the cleaning effect is in the outside of the container Flushing fluid added intermittently compressed air, causing the Pressure of the flushing fluid is increased and also stronger Deposits or blockages from the pipeline ripped out and rinsed out.

For this, the compressed air is fed in via a compressed air pipe introduced the container and the other directly over the Compressed air line in the pipeline to be cleaned or Brought flush line, this additional Compressed air supply through a manually operated shut-off device is controlled. It is also advantageous that the fiction according device no connection to a water tap required and the flushing fluid pressure is variable.

The entire device is simple and economical assembled, easy to transport to the place of work, there via a quick coupling with the pipeline to be cleaned to connect and connect to a compressed air generator.  

This closed system prevents contamination on Avoided place of work.

The device shows due to its mode of operation with rinsing liquid and additional compressed air Way of working.

In the drawing, an embodiment of the Invention shown, which in more detail below is explained.

The only figure shows a schematic Representation of the cleaning device.

The transportable device for removing deposits and blockages in sanitary pipelines 1 has a container 3 which can be filled with a rinsing liquid 2 as a pressure container. From this container 3 , a riser pipe 4 is led out, which has a connection 5 to the pipeline 1 to be cleaned or a flushing line 6 .

A compressed air line 7 is connected to the riser pipe 4 , from which a compressed air pipe 8 led into the container 3 for pushing out the flushing liquid 2 passes through the riser pipe 4 and into which a manually operable shut-off device 9 for intermittent release of the compressed air 20 into the outflow from the riser pipe 4 Rinsing liquid 2 is used.

In the compressed air line 7 , a T-piece 10 with a manometer 11 is also inserted, from which the compressed air pipe 8 branches off and opens into the neck 3 a of the container 3 next to the riser pipe 4 .

In the flow direction "A" of the compressed air 20 , the shut-off device 9 , which is formed by a tap with a hand lever, is located behind the T-piece 10 and in front of the connection point 12 between the compressed air line 7 and the riser pipe 4 .

The connection 5 of the riser pipe 4 is formed by a quick coupling to which the rinsing pipe 6 which can be inserted into the pipe 1 to be cleaned or the pipe 1 which is to be cleaned can be connected directly.

The container 3 has an outlet 13 in the bottom area, such as a valve, tap, or the like.

To the compressed air line 7 is connected in front of the T-piece 10 via a quick connector 14 from a T-piece 15 with pressure relief 15 a for the container 3 , a check valve 16 , a shut-off valve 17 and possibly a pressure regulator 18 , unit 19 connected.

The container 3 is or is filled on site via its connection 5 with the rinsing liquid 2 , which can be formed by cold water, hot water or chemical liquid, which can flow into the container 3 through the riser pipe 4 .

The portable pipe cleaning device is connected on site with the compressed air line 7 to a compressed air generator (compressor).

Then the flushing line 6 is connected to the connection 5 and introduced into the pipeline 1 to be cleaned, wherein an inflatable bellows for sealing the pipeline 1 can be attached to the flushing line 6 so that the flushing liquid 2 cannot strike back.

Now the shut-off valve 17 of the assembly 19 is opened and the compressed air 20 flows in the direction "A" through the compressed air line 7 up to the shut-off element 9 and via the compressed air pipe 8 into the container 3 and acts on the flushing liquid 2 , which then flows through the riser pipe 4 flows upwards into the flushing line 6 and enters the pipeline 1 under pressure, which causes the pipeline 1 to be flushed and cleaned.

To intensify cleaning of the pipeline 1 , the shut-off element 9 is then briefly opened by hand at certain time intervals, as a result of which the pressure in the flushing liquid 2 is increased by the additional compressed air 20 and also strongly adhering deposits or severe blockages are torn out of the pipeline 1 and washed away.

Depending on the pressure display, the removal of the blockages can be recognized on the manometer 11 .

Depending on the type of sanitary line, a suction cup or another sealing part can be connected to the flushing line 6 .

In a preferred manner, the pipe cleaning device is designed to be detachable from its container 3 , in that a lid 21 is detachably fixed on the container neck 3 a, for example by a bayonet or screw lock. With this cover 21 , the two pipes 4 , 8 are connected to form a unit, and the riser pipe 4 can be separated below the cover 21 , for example by means of a screw connection 22 , plug connection or the like.

Due to the detachable arrangement of the container 3 , the pipe cleaning device can also be used for pressing containers of various types.

A shut-off valve or tap 23 is inserted into the compressed air pipe 8 .
