2o22yadní._stay_technikx

Normal piping water, but also spring water, usually contains dissolved minerals, especially lime, which settles in installation areas such as heat exchangers, boilers, cooling units, taps, and last but not least in the pipeline and over time adversely affects the suitability of paint installation installations. device. This applies to the formation of metal oxides, for example rust and associated installation parts. In addition, industrial installations, such as water cooling systems, produce deposits of various kinds which have a negative effect on the function of a plurality of pipe systems. This method is also suitable for removing deposits that are already in the piping system, but this is not a satisfactory result in terms of efficiency.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method and apparatus of the type described in the introduction which provide improved efficiency in comparison with the known solutions.

The object of the present invention is that, by means of at least one ultrasonic source arranged in the piping system and surrounded by a water source, it is sold to the piping system of ultrasonic vibrations. Surprisingly, it has been shown that ultrasonic waves have volumetric cleansing agents on the inside of the piping system, wherein the liquid medium present in the piping system, for example water, is a cleaning medium. Water is suitable for the transmission of ultrasonic vibrations, so that ultrasonic wave cleaners in the piping system broaden the oxen and their effect is manifested even in distant areas.

According to an embodiment of the invention, the radiated energy source is oscillating ultrasound sources unilaterally in the longitudinal direction of the pipe of the pipe system, preferably in the direction of water flow.

It has further been found that the possible cleaning effect of the method according to the invention is further increased by the use of a further source of ultrasound generating oscillations which run obliquely or perpendicularly to the tubes of the pipe system.

As a source of ultrasound, it has preferably used a piezoelectric sound transmitter which has the advantage that it can be produced in any shape.

By controlling or adjusting the frequency and / or energy of the kinetic energy of the radiated ultrasonic oscillation, it is possible to adjust the frequency and / or energy of the oscillation according to the data provided by the installer, in particular the data of the type of tisazetiiri, means black-brown for rust or white for lime deposits, the lira is allowed to be operated according to the invention by its use at cutting frequencies δ and / or with different oscillating energy. Selecting the appropriate operation can be done with a simple switch.

In order to prevent overheating in the transport of the ultrasonic source or over-formation of bacteria by the action of too warm water in the day of the transport of the ultrasonic source, it is expedient to adjust the temperature control to a suitable source of ultrasound; However, if the corresponding ultrasound source is bypassed with water in the duct system, there is no risk of overheating. However, if the water in the ultrasound source area has been standing for a long time, there is lacquer warming with the corresponding®. overheating possible.

In order to prevent lacquer overheating and / or particularly loose debris from depositing during the cleaning process, but also to prevent new deposits, in a newly installed or existing piping system, according to a further advantageous embodiment of the invention, the corresponding sale is carried out. ultrasonic oscillations into the piping system, within specified time iutervaleoh, it is intermittent. For example, it may be performed at minute or even hourly time intervals.

and

In such a case where there is an attempt to remove deposits in the duct system but it is not known what kind of deposits are involved, it is advantageous to carry out the appropriate transfer of ultrasonic oscillations to the duct system with alternating oscillation frequencies, thereby achieving, that sediments are exposed to multiple possible frequency oscillation frequencies, which is particularly effective,

A particularly good effect of the process according to the invention is achieved if the respective transfer of ultrasonic vibrations to the piping system is carried out with vortices superimposed on each other by the oscillating frequencies. For example, starting from a fundamental oscillation in the region of 25 Hz, this fundamental oscillation is superimposed on the upper oscillation in the ultrasound region, for example 4,55 crises.

To solve the above object, the device according to the invention is characterized in that at least one source of ultrasound is provided in the housing and the housing is integratable into the piping system so that the ultrasound source is in a state of transmitting its energy to the water in the piping system.

According to an expedient embodiment, the source of ultrasound is in a resonator, which emits oscillations produced by the source of ultrasound, wherein the resonator is in contact with water and is surrounded by a two-case other casing which is continuous with the piping system.

In order to ensure efficient transmission of ultrasonic vibrations, the resonator consists of a solid material, the ultrasonic source being arranged in the recess of the resonator and the recess being closed by a lid. The main oscillation direction of the ultrasonic source can be influenced by the shape of, for example, the shiny disk and the arrangement of the ultrasonic source inside the resonator. When the disk-shaped ultrasonic source is arranged perpendicular to the longitudinal axis of the piping system. In order to ensure that the resonator contacts the water of the piping system as closely as possible, it is provided according to a further preferred embodiment of the invention that the resonator is provided with receiving lugs which engage the inside of the housing and a circumferential gap is provided between the housing and the resonator. , which ensures that the resonator is surrounded by water, with the exception of the pins of the pins, so that the resonator is connected to the housing only by means of its pins.

Preferably, these deposition projections consist of a flexible material, for example a flexible plastic lunar or rubber, so as to prevent unpleasant noise in the piping system due to the low-frequency oscillations, especially when using low-frequency base oscillations,

To increase the intensity of cleaning, the device is provided with at least one additional ultrasonic source which transmits oscillations obliquely or perpendicular to the longitudinal axis of the housing. In such an arrangement, the housing may not have an annular recess in which an annular or semi-annular source of ultrasound is provided that at least partially surrounds the resonator.

The ultrasonic source transmits its oscillation energy directly to the housing of the cleaning device and thus to a pipe system which is rigidly connected thereto. This states /

the piping system can be further increased, as already mentioned, the cleaning effect. Particularly in highly polluted piping systems, this arrangement allows at least a temporary introduction of the piping system into oscillations, thereby substantially intensifying the cleaning effect.

According to an analogous arrangement, an annular or semi-annular source of ultrasound is provided to achieve the same effect directly on the outside of the pipe wall of the piping system.

The invention is described in more detail below with reference to the drawing. For simplicity; identical features are found with only one reference feature.
