Description

Piping Cleaner {PIPE CLEANING APPARATUS}

The present invention relates to a pipe washing apparatus, and more particularly, after the steam heated at a high temperature in a steam generating tank is injected into a pipe to be cleaned at a high pressure, the water heated in the steam generating tank is supplied as washing water into the pipe. The present invention relates to a pipe washing device for cleaning and sterilizing pipes.

In general, pipes installed for fluid flow, including hot water, have a scale (or sludge) formed therein due to corrosion by oxidation or various foreign matters contained in the fluid while the service period is elapsed depending on the material thereof. Sticks or sticks.

In general, the scale in the pipe is formed by the presence of cations such as calcium and magnesium in the raw water together with the carbonic acid and reacting with temperature to form calcium carbonate or magnesium carbonate and the like. It is formed by being attached to the wall of the pipe.

Here, typically, calcium carbonate is the most common component that generates sludge among the salts dissolved in the feed water through the pipe. Since the solubility of such calcium carbonate increases with increasing temperature, it is usually precipitated at low temperature.

As such, if a scale (sludge) is formed on the inner surface of the pipe, the inner diameter of the pipe is gradually narrowed, which reduces the flow path and causes the smooth flow of fluid in the pipe. In the case where the flow of the fluid is disturbed by the scale (or sludge) in the air, the increase in the pressure of the fluid increases the possibility of adversely affecting the pipe.

Therefore, the scale (or sludge) formed in the pipe is preferably removed by applying an appropriate method or means. For example, a chemical is injected into the pipe to react with the scale to remove it. In case of removing scale inside pipe, it is necessary to use highly toxic chemicals depending on the components of the scale or additional cleaning by supplying the washing water to remove chemicals in the pipe after the scale is removed by chemical injection. This is likely to entail environmental pollution.

Another example for cleaning the pipe is a method of removing the scale inside the pipe by rotating the flexible wire by an electric motor. In the case of removing the scale (or sludge) inside the pipe using the flexible wire, a relatively long flexible wire is used. Not only have to be always equipped with a wire storage box, but the overall structure including the electric motor and the flexible wire rotating by the electric motor and the wire storage box accommodating the flexible wire are complicated and the electric motor and the flexible wire are operated to clean the pipe. The work to remove scale (or sludge) inside the pipe is relatively complicated.

In addition, if the possibility of germ propagation is considered after washing the inside of the pipe by the flexible wire, sterilization / sterilization treatment of the pipe is preferable, so that the sterilization / sterilization process can be performed by a simple process. A structure is needed.

Accordingly, the present invention has been made in view of the above-described state of the art, and removes scale (or sludge) inside the pipe by injecting high temperature steam into the pipe at high pressure, and generates water having high temperature steam. An object of the present invention is to provide a pipe piping washing apparatus for supplying the washing water to the inside of a pipe to remove residual scale components so that sterilization / sterilization treatment on the inner surface of the pipe is also performed.

In order to achieve the above object, according to a preferred embodiment of the present invention, steam generation water for generating steam to remove scale (sludge) in a pipe is stored and a water supply port for supplying the steam generation water is provided. A steam generator, a controller for controlling a process of removing scale (sludge) in the pipe by using steam generated in the steam generator and water heated therein as washing water, and installed in the steam generator A heater for heating the steam generating water under the control of the control unit, installed in the steam generating tank to detect the temperature of the steam generating water heated by the heater to apply to the control unit to control the operation of the heater Temperature detection sensor for the water level is formed on one side of the steam generating tank to indicate the water level of the steam generating water Bell pipe, a high pressure accelerator for high-pressure acceleration of the high temperature steam generated in the steam generating tank to be injected into the pipe, for supplying the water heated in the steam generating tank to the pipe as the washing water under the control of the controller. Provided is a pipe washing apparatus including a washing water pumping unit and an electronic control valve for opening and closing a path of the washing water under the control of the controller.

According to the pipe washing apparatus according to the present invention described above, the hot steam generated in the steam generating tank is intermittently or continuously injected by a high pressure accelerator to dissolve and discharge the scale (or sludge) component including calcium carbonate in the pipe. Afterwards, the heated water in the steam generator is supplied to the inside of the pipe as washing water to discharge residual scale components, thereby enabling the inside of the pipe to be cleaned and sterilized / sterilized.

That is, according to the present invention, the controller 12 preferentially causes the steam generated by the steam generating tank 10 to be supplied into the pipe at a high pressure (for example, 5 to 6 kg / cm 2) automatically or selectively. The water heated in the steam generator 10 is supplied to the inside of the pipe as washing water, so that the scale (sludge) component is removed.

In addition, a heater 14 for heating the steam generating water supplied to the steam generating tank 10 to a high temperature (for example, 150 to 180 ° C.) under the control of the controller 12 inside the steam generating tank 10. Is placed.

In addition, a temperature detection sensor 16 is installed in the steam generating tank 10 to detect the temperature of the steam generating water and apply it to the control unit 12, and the control unit 12 has the temperature detection sensor 16. The heating temperature of the steam generating water by the heater 14 is controlled based on the temperature detected at.
