DE3021051A1 - High pressure flushing and suction cleaning system - has winches for high pressure and suction pipes rotatably mounted on single swivelling arm - Google Patents

Abstract

The high pressure flushing and suction appliance is used for cleaning sewerage systems or removing industrial wastes. The appts. includes a pressure pipe, connected to a high-pressure pump, and a suction pipe, connected to a suction pressure tank. The pipes are rolled up on winches. A swivelling arm has both the winches rotatably mounted on it. The arm, in turn, is pref. on a swivelling mounting on the suction pressure tank. The sections of the two pipes running out from the winches are pref. located at a short distance apart. This arrangement makes it easier to introduce the pipes into the delivery position for the ducting system.

Title: High pressure flushing and suction device

The invention relates to a high pressure flushing and suction device with a pressure hose that is connected to a high pressure pump and with a suction hose that is connected to a suction pressure tank is connected, both hoses are each wound on a reel.

Such devices have been used for many years for the disposal of sewer systems or for cleaning process engineering Equipment used in industry. They are designed as mobile or stationary combination devices that can perform two operations at the same time in one device. For this purpose, the pressure hose is filled with pressurized water applied and introduced into a pipe system to be cleaned. At the beginning of the hose there is an appropriately designed one Nozzle attached, which is propelled with the reaction force from the recoil of the exiting water. The end The water exiting the nozzle washes away the existing contamination and brings the rinsed off when the pressure hose is withdrawn Dirt particles back to the input point of the pressure hose. This is where the alluvial dirt becomes sucked into a suction pressure container by means of negative pressure via a movable suction hose connection. Both working

processes generally take place simultaneously.

The pressure hose, which is inserted into the pipeline system at the input point, is based on a known, often swiveling hose reel wound up in the required working length. The movable suction hose connection to suck off the alluvial debris must be introduced into the same input point of the pipeline system will. The difficulty always arises because the input points are not always accessible and the The swiveling ranges of the hose reel and the movable suction hose connection do not match, so that both inserted tubes do not fit into the relatively small diameter input point at the same time.

The invention is based on the object of a high-pressure flushing and to improve suction device of the type mentioned in such a way that the difficulties mentioned during insertion of the hoses into the entry point of the pipeline system can be avoided.

This object is achieved according to the invention in that at the two reels are rotatably arranged on a swivel arm, preferably those running down from the two reels Trui / s of the two tubes at a short distance from each other arranged.

An embodiment of the invention is shown in the drawing and is explained in more detail below. Show it:

Fig. 1 is a plan view in partial section of the arrangement according to the invention and

FIG. 2 shows the rear view of FIG. 1.

A suction pressure tank 2 is set up on a vehicle 1, which is only indicated schematically. At the end of the suction pressure tank 2, which is closed with a bottom 3 on the front side, carries the jacket of the suction pressure container a fitting 4 on which a swivel arm 5 is pivotably mounted is. On the side of the swivel arm 5 facing the bottom 3, for example with a spherical ring 6, an in attached to the longitudinal axis of the suction pressure container 2 rotatable suction hose reel 7 for a large suction hose 8. This Suction hose 8 is equipped with a conventional rotatable swivel pipe coupling 9, a swivel pipe 10 and a connecting hose 11 is connected to the connecting piece 12 entering the floor 3. The change in length of the connection from the Swiveling pipe coupling 9 for connecting piece 12 takes over When the swivel arm 5 is swiveled out, the swivel tube 10 with the connecting hose 11 automatically.

In practice, the suction hose 8 generally has a clear diameter of 100 to 150 mm and a useful one Length of about 10m to achieve the suction depth that can be achieved by the vacuum to take advantage of. The suction hose 8 is passed through the input point together with a pressure hose to be described later 13 introduced into a pipeline system 14. The material is removed from the suction hose 8 in the direction of arrow A sucked out of the pipeline system 14 and through the connection piece 12 in the direction of arrow B into the suction pressure vessel 2 funded.

On the side of the swivel arm 5 facing away from the bottom 3, for example with a second ball ring 15, a pressure

hose reel 16 for a pressure hose 17 attached. This pressure hose 17 is connected to a conventional rotatable swivel pipe coupling 18 with a high-pressure pump, not shown tied together.

In practice, the pressure hose 17 generally has a clear diameter of 20 to 40 mm and a length of about 140 m. At its front end it has a nozzle 19 from which the pressurized water flows in the direction of arrows C. exit.

As can be seen from Fig. 2, the pressure hose reel 16 is arranged axially offset from the suction hose reel 7, that the running strands of the hoses 8 and are as close to each other as possible.

In the position shown in Fig. 1, both reels 7 and 16 are ready for operation with the smallest overhang of the vehicle 1. You can also, because they are attached to the common swivel arm 5, over the diameter of the suction hose reel 7 can be pivoted about 270 ° as a radius. The pivoted position is shown in Fig. 1 by the dash-dotted line Line drawing reproduced, with an adjustment by about ^ 120 ° is shown. The swivel range becomes like this great that all work can be carried out that cannot be achieved with the known devices. Another advantage is given when cleaning sewers The reels 7 and 16 can be swiveled out by 90 ° in the street area. The vehicle is then outside the middle of the road and does not affect oncoming traffic.

1300S0 / 0327

Both reels 7 and 16 are operated independently of one another with a hydraulic power drive, for example, whose Performance corresponds to the required working method.

The switching elements for the drive are attached to the swivel arm 5 and thus in the respective working position to operate.
