Definitions

  • the present invention proposes a device for the descaling of pipes and apparatuses in heating and cooling installations, especially small and middle plants such as wall water-heaters, geysers, boilers, refrigerator exchangers, heating and cooling plates, heat exchangers, cooling circuits, pipes for the supply of hot water to the use points, etc.
  • the device according to the present invention can be employed to remove calcareous deposits from any kind of pipes or apparatuses.
  • the present device can be utilized in many situations where there is the problem of the formation of lime or hard deposits caused by the passage of water.
  • the present invention proposes to employ a very simple device to descale pipes so that it is no more necessary to utilize the conventional expensive complex devices.
  • the device according to the present invention permits to make use of the common tools that are available.
  • the known prior art discloses some solutions to dissolve the calcareous deposits in the pipes. These prior art solutions refer to devices that deliver appropriate acids to the encrusted pipes to dissolve the hard deposits.
  • the prior art devices comprise both a reservoir that contains an acid and a pump that supplies the encrusted pipes with the acid solution, the pump being actuated by means of a high-power motor.
  • the aim of the present invention is therefore to solve the above inconveniences and drawbacks by carrying out a very simple and cheap device.
  • the simplicity and low cost of the device according to the present invention is made possible by the absence of the expensive cumbersome electric motor of the prior art devices.
  • the main advantage of the device according to the present invention is therefore its great simplicity and consequent low cost, which makes the present device very appreciated by the consumers.
  • Figure 1 denotes a device according to the present invention on the whole for the descaling of pipes, in particular pipes of heat exchanging installations such as boilers or the like, but generally speaking pipes of all those apparatuses and installations in which there is the problem of the formation of calcareous deposits.
  • the device 1 comprises a reservoir 2 which contains an acid liquid to be delivered by means of a pump 5 through a supply duct 3.
  • the return of the acid liquid occurs through a return duct 4.
  • the peculiarity of the present invention is the presence of a pump 5 and a supporting arm 6 which supports a power-driven tool 7.
  • the power-driven tool 7 may be any tool that is available. It may be a power drill or whatever power-driven tool provided with a power rotary spindle.
  • the upper part of the pump 5 shows a seat in which the power-driven tool 7 is inserted.
  • This pump seat must be shaped in such a way as to house and hold the tool.
  • the tool rotates the pump so that the pump delivers the acid to the supply duct 3. Then, the acid returns through the duct 4 to the reservoir 2.
  • Both the pump connection and the tool support can be provided with a universal connection to connect tools of any kind and size. It may be also an interchangeable connection.
  • the actuating tool is provided with a reversible motor such as a power drill, it is possible to take advantage of the peculiarity of the reversibility to better descale the encrusted pipes.
  • the acid flows in the pipes back and forth in both directions.
  • the utilization of the so-described device is very simple. It is sufficient to insert the power-driven tool 7 in the support 6 so that the tool inserts in the connection of the pump 5. Then, the parts in question must be blocked through conventional blocking means. Then, the ducts 3, 4 are connected with connections of an apparatus A to be descaled. Now, it is sufficient to actuate the power-driven tool 7 to permit the pump 5 to rotate so that the acid begins flowing in the supply duct 3. From the supply duct 3 the acid reaches internal pipes of the apparatus A to be descaled and returns through the duct 4 to the reservoir 2.
  • the so-described device is very simple and its cost is very low because unlike the prior art devices there is no electric motor in the present invention.
  • the present device can be easily transported because its dimensions are not cumbersome.
