Description

Water pipe cleaning device using micro ozone bubble

The present invention relates to a pipe washing apparatus for cleaning pipes applied to building structures, and more particularly, to convey ozone supplied from the ozone generator in a confined state through bubbles generated from the bubble generator, and thus to clean the inner wall of the pipe. It relates to a pipe washing apparatus using ozone microbubbles (bubbles) to remove foreign substances in the.

Usually, home. Pipes for water supply and drainage are essentially installed in various architectural structures such as apartments, and the pipes are used to supply external sources and water stored in the underground or rooftop storage tanks to each supply pipe.

The above pipes are for water supply and drainage, and once installed, they are used for a long period of time.As time passes, rust occurs due to corrosion, various foreign substances are deposited, and various microorganisms and bacteria are formed. When discharged, it causes pollution.

In addition, when the pipe is used for a long time, calcium carbonate, iron oxide, silica, calcium phosphate, etc. remain inside the pipe, and through this, scale is formed on the metal surface, and the above-described scale is hardened on the inner wall of the pipe, resulting in a sharp drop in heat transfer efficiency. It is becoming a factor to drop.

That is, the water pressure inside the pipe increases due to the scale hardened on the inner wall of the pipe, and in this case, there is a problem in that the pipe is partially damaged due to the water pressure or various foreign substances are generated as the scale is separated from the pipe.

In order to solve this problem, the pipe can be replaced, but in this case, a lot of cost, long construction period, and inconvenience are followed. Therefore, a significant number of people continue to use contaminated water or suffer from problems such as a decrease in heating efficiency.

To solve this problem, the pipe is periodically cleaned, and the inside of the pipe is cleaned using a high pressure washing method or ozone water during the washing operation.

The above-described pipe washing apparatus using ozonated water adopts a method of forcibly supplying ozonated water using a compressor, so ozone is oxidized when passing through the compressor, and when heat is generated in the process of compressing ozone, the ozone concentration is reduced. Accordingly, there is a problem that the strength of the pipe washing is weakened.

The background technology or the prior art described herein is information possessed by the present inventors or acquired in the process of deriving the present invention, and is only intended to help understand the technical significance of the present invention. It is stated that it does not mean a well-known technology in the field.

That is, the tube 110 of the water supply unit 100 is connected to the other side of the body 320 constituting the bubble generator 300 to supply water to the mixing chamber 340 formed inside the bubble generator 300 It is supposed to be.

Here, in the case of supplying the water in the reservoir 120 to the bubble generator 300, it will be preferable to supply the water at a pumping pressure through the pump P.

In addition, it is preferable that the air supply unit 500 is installed in the bubble generator 300 to induce an aeration action of water introduced through the water supply unit 100 to form bubbles, and the air supply unit 500 When air is supplied to the inside of the bubble generator 300 through the tube 510, it is preferable to be supplied in a spray form so that a large amount of air bubbles is formed.

The bubble generator 300 is to allow the water supplied from the water supply unit 100 to be transferred into the pipe B while forming a large amount of bubbles, and the body 320 fixed to one side of the moving device 101 ), a mixing chamber 340 formed inside the body 320 to form bubbles while mixing incoming ozone, and a bubble supply port 360 guiding the discharge of bubbles formed in the mixing chamber 340 ).

That is, when the supplied water generates bubbles, ozone is supplied together with the bubbles so that ozone bubbles are formed.

The mixing chamber 340 is for forming ozone bubbles and is formed to form an inclination angle 342 gradually reduced in the direction of the bubble supply port 360 so that the inner diameter induces pressure, and the bubble supply port 360 ) Is connected to a tube 410 connected to the nozzle pipe 400.

In addition, in the mixing chamber 340, the front end of the ozone outlet 220 of the ozone generator 200 is positioned to pass the ozone generated from the ozone generator 200 through the ozone supply hole 222 of the ozone outlet 220. It is configured to discharge evenly into the mixing chamber 340.

In addition, the inner wall of the mixing chamber 340 is for inducing a bubble action while the incoming water hits the wall, and may be manufactured in various shapes.

The bubble supply port 360 is formed in a protruding shape on one side of the body 320, and a reverse end 362 is formed to protrude to prevent separation when the tube 410 is fixed to the tip.

The ozone outlet 220 is coupled to the center of the other side of the body 320 of the bubble generator 300, and its tip protrudes coaxially with the bubble supply port 360 and is located in the mixing chamber 340.
