Description

[0001] Apparatus for Portable Pipe Cleaning Assembly [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable pipe cleaning assembly, and more particularly, to a portable pipe cleaning assembly in which a washing liquid tank and a washing liquid tank, in which water and a cleaning agent are mounted, And a cleaning device capable of guiding the user to a situation in which the liquid is sprayed.

Generally, heating pipes and water pipes are installed in houses, apartment buildings and factories. In the case of the piping thus installed, once it is installed, the microbial film, rust, scale and the like accumulate on the inner surface of the piping as time goes by due to the characteristic of being used for a long time.

Therefore, when a pipe is used for a long period of time, a microbial film such as iron bacteria is formed inside the pipe, and a local cell may be formed there. With the local cell thus formed, the iron is dissolved in the inside of the lump, and the lump is deposited with the iron oxide, so that the lump is gradually enlarged. In this lump, the iron bacteria are inhabited and the corrosion is continuously generated in the inside of the pipe.

According to microbiological studies in the water supply piping made by the Netherlands Waterworks Research Institute, microbial nutrients are included in the tap water, regardless of the corrosion of the metal.

That is, if the nutrients of the microorganisms are contained in the tap water, the microorganisms are formed in the pipelines due to the increase of bacteria in the pipelines, and a large invertebrate animal that feeds the microorganisms is required to be cautioned.

Accordingly, there is a demand for scaling of pipelines, removal of microbial membranes inevitably formed on non-corrosive materials, and sterilization and cleaning methods for sterilizing various microorganisms including bacteria.

In order to solve such a conventional problem, researches on cleaning inside the water pipe have been actively conducted.

For example, in Korean Utility Model Registration No. 20-0389135 (registered on Jun. 29, 2005), "Pipe cleaning device using ozone water and air bubbles" is disclosed.

The present invention relates to an apparatus for cleaning the inside of a pipe using ozone generated by an ozone generator, and is installed in a connection portion between a supply pipe of a pump connected to a water tank and an ozone supply pipe, An injector for simultaneously introducing the generated ozone; A mixer connected to an injection port side of the injector for uniformly mixing ozone with water passing through the injector; And a bubble generator installed between the mixer and the pipe for generating a large amount of bubbles.

In such a construction, although the inside of the pipe is cleaned by using air bubbles and ozone, the ozone water is used in a low concentration owing to insufficient ozone water dissolving technique, which is not effective. The experimental results show that the non-corrosive materials such as polyethylene pipes can not remove scales from corrosive materials such as manganese and iron, which are formed by complete removal of microbial film and deposits of heavy metals, and galvanized steel pipes. There is a problem.

In addition, Korean Patent Laid-Open Publication No. 10-1992-0015052 (published on Mar. 12, 1994) discloses "a pipe scale removing agent for domestic boilers ".

The present invention relates to a scaling agent for boiler piping comprising 20% by weight of citric acid, 10% by weight of phosphoric acid (H3PO4), 10% by weight of surfactant, 10% by weight of ethyl alcohol, 5% And the like. The custom-made composition thus prepared is diluted to 5% by weight with respect to the irrigation water capacity of the pipe, circulated for 24 hours, and then discharged, whereby the inside of the pipe is cleaned.

In the tubular tubular composition using citric acid, a capillary containing citric acid is diluted to the capacity of the irrigation water so that the capillary accumulated on the inner wall of the pipe is decomposed and removed according to the flow of the irrigation water in the pipe. However, there is a limitation in that the inner wall of the pipe is simply cleaned according to the flow of the irrigation water, and thus there is a problem that the ability to decompose and remove the iron ore is insufficient.

Therefore, there is a need for a method capable of improving the decomposing and removing ability. The apparatus is structured so as to be complicated and inconvenient to carry, There has been a problem in that it is required to directly operate.

SUMMARY OF THE INVENTION The present invention has been made in order to overcome the problems of the prior art, and it is an object of the present invention to provide a pipe cleaning apparatus which is easy to carry.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale and wherein like reference numerals in the various drawings refer to like elements.

1 is a perspective view showing the appearance of a portable pipe cleaning assembly.

Referring to FIG. 1, the portable pipe cleaning assembly of the present invention comprises a pipe cleaning apparatus 400 including a cover 410 and a main body 420.

A cover 410 having a slope on both sides and a handle 411 formed on the central portion of the slope and a body 420 coupled to the cover 410 via a hinge so as to be able to open and close the cover 410 And a pipe cleaning device 400. That is, the outer shape of the pipe cleaning apparatus 400 is shaped like a triangular pillar (cover 410) laid on a hexahedron (body), and has a shape generally used for expressing a house on a map or the like.

The main body 420 should have an inner space of sufficient size to mount various auxiliary materials for cleaning the piping 200 so that the piping 200 can be cleaned. Therefore, various subsidiary materials for washing the pipe 200 through the main body 420 are not exposed to the outside, so that they can be easily protected from an external impact or the like. The cover 410 serves to close the open side of the inner space of the main body 420 and serves as a kind of lid. However, the upper surface of the cover 410 is inclined so as to have a triangular shape when seen from the side, and a handle 411 is formed on the center of the upper end to facilitate the user to carry it.

In addition, a side handle 411 may be provided on the side surface of the body so that the user can grip the handle 411 by hand, and the number or shape of the handle 411 formed at this time is not limited to a specific limit There is no.

In addition, one of the inclined surfaces formed on the cover 410 is attached to a display unit of the inflow meter 310 and the discharge meter 320, which will be described later, to be exposed to the outside so that it is easy for the user to check the measured inflow amount and the discharged amount, It is also possible to form a control panel interlocked with the compressor 700 so that the user can easily control the pipe cleaning assembly. It is also possible to attach a heat discharging device to the other inclined surface so as to discharge the heat generated from the inside to the outside. In addition, the main body 420 and the cover 410 are coupled to each other by a hinge so as to be openable and closable. At this time, a locking device may be additionally provided on the opposite side where the hinge is located so as to maintain a more firmly locked state .

2 is a perspective view showing the internal structure of the pipe cleaning apparatus 400.

The inner space of the main body 420 is provided with a piping 200 composed of an inflow pipe 210 and a discharge pipe 220 as a passage through which the cleaning liquid moves and an inflow valve 110 And a discharge valve 120. A compressor 700 for pressurizing and injecting the cleaning liquid and a meter 300 for measuring the flow rate of the cleaning liquid which is installed in the valve 100 and moves .

First, the compressor 700 serves to discharge the cleaning agent and water introduced from the outside to the high pressure again. Therefore, it is possible to realize that the inflow valve 110 is formed at one side as an inlet for receiving the cleaning liquid and the inflow pipe 210 is coupled to the inflow valve 110, It is possible to form the discharge valve 120 as a discharge port on one side and to connect the discharge pipe 220 to the discharge valve 120.

Next, the meter 300 measures the amount of the washing liquid to be introduced or discharged and displays it numerically to the user. The meter 300 includes an inlet meter 310 attached to the inlet valve 110 and a drain meter (not shown) attached to the drain valve 120 320). The inlet meter 310 and the drain meter 320 can be configured using a variety of known meters 300 such as a meter 300 or a digital meter 300 of the slide analogue method in common use. The meter 300 may also include a pressure gauge to simultaneously check the air pressure and the discharge pressure. Such a pressure gauge will be described later.

4 is a conceptual view showing the internal structure of the washing liquid tank 500 and the auxiliary tank 800, and FIG. 5 is a schematic view showing the internal structure of the washing liquid tank 500 and the auxiliary tank 800. FIG. FIG. 3 is a perspective view showing the final combined shape of the pipe cleaning assembly. FIG.

3, 4 and 5, in addition to the configuration of the preceding pipe cleaning apparatus 400, the cleaning tank 500 may further include a cleaning liquid tank 500. The cleaning liquid tank 500 is a structure provided separately from the pipe cleaning apparatus 400. The cleaning liquid tank 500 is composed of a cleaning liquid storage unit 510 for storing the cleaning liquid in the inner space, The tank 500 is connected to the inflow pipe 210 and serves to supply a cleaning liquid. In this case, it is necessary to control the discharge of the cleaning liquid. Therefore, the cleaning liquid discharge valve 520 is opened and closed so that the cleaning liquid is discharged from the one side of the cleaning liquid storage part 510 to the inflow pipe 210.

Here, the cleaning liquid refers to a cleaning agent which is a liquid medicine for removing stains, rust, scale, etc. of the pipe 200 and water used for cleaning. For example, liquid hydrochloric acid or sodium hydroxide corresponds to a detergent.

It is possible to use these detergents or water separately. However, if the cleaning agent can not be wiped completely, it may cause corrosion of the inside of the pipe 200 to be cleaned. In case of the old pipe 200, the inside of the pipe 200 may be damaged May be worn. Therefore, it is also possible to perform cleaning with water alone without using a cleaning agent.

Generally, in most cases, the cleaning agent is diluted with water without using the detergent for washing the piping 200. For this purpose, it is necessary to provide a separate cleaning agent and water, and separately supply or mix them.

In order to cope with such a demand, the inner space of the washing liquid tank 500 may be divided into a water storage part 511 for storing water in the inner space and a detergent storage part 512 for storing the detergent in the inner space. Correspondingly, the cleaning liquid discharge valve 520 is composed of a water discharge valve 522 for controlling the discharge of water and a cleaning agent discharge valve 521 for controlling the discharge of the cleaning agent.

The washing liquid tank 500 is also provided with a water discharge valve 522 for controlling the discharge of water and is connected to a washing agent discharge valve 521 through which the washing agent is discharged, And is connected using a pipe 530. In this case, even when the Y pipe 530 is connected due to the characteristics of the portable pipe cleaning assembly, it is necessary to ensure portability and durability when cleaning the pipe 200. Accordingly, the Y piping 530 is connected to the water discharge valve 522 and the cleaning agent discharge valve 521 of the cleaning liquid tank 500, and a separate auxiliary tank 800 is further provided so as to be portable while ensuring durability after the connection. And the Y piping 530 is mounted inside the auxiliary tank 800. The auxiliary tank 800 may further include a fixing member or an interior material for fixing the Y pipe 530 to prevent the Y pipe 530 from moving due to vibration or an external impact so that the connection is released or damaged. to be.

Here, the Y pipe 530 includes a water discharge pipe 532 connected to the water discharge valve 522, a cleaning agent discharge pipe 531 connected to the cleaning agent discharge valve 521, a water discharge pipe 532 and a cleaning agent discharge pipe 531, And a branch pipe 539 extending from the check valve 533 to the inflow pipe 210. The check valve 533 controls the flow of the cleaning liquid in one direction.

At this time, the check valve 533 controls the passage of the pipe extending in multiple directions by one valve 100, and is generally located at the intersection of the pipe having the directionality of three directions or more and the check valve 533 is rotated Which means the valve 100 for setting the direction of the passageway that is passed through. That is, the mixing ratio of the cleaning agent and the water can be forcibly controlled through the check valve 533, and the check valve 533 can be controlled so that only the cleaning agent comes out from the movement or only the water comes out, It is also possible to control.

The bulb 539 has a larger volume than the peripheral portion of the branch pipe 539 at the lower end of the check valve 533 and connected to the inflow pipe 210, And a mixing block 534 having the free porous mixing hole 535. [ The mixing block 534 serves to assure that the cleaning agent and the water are mixed more reliably when the cleaning agent and the water are simultaneously introduced. Although both the detergent and water are liquid, they may be discharged in different amounts, and their density or properties may vary, resulting in leakage without being easily mixed. In order to prevent such a phenomenon, the porous mixing port 535 is positioned at the lower end of the check valve 533, which is the initial mixing point, so that the cleaning agent and water can be mixed with the cleaning agent and water more effectively through the porous mixing port 535 A mixing block 534 is formed.

The mixing block 534 may be formed in a rectangular shape at the lower end of the check valve 533 and formed to have a larger volume than the peripheral portion of the Y pipe 530. The mixer 535 is provided inside the mixing block 534 and is provided in the form of a porous ball so that liquid can be freely flowed in and out. It is preferable that the mixing bowl 535 is formed inside the support so as not to block the discharged portion of the mixing block 534 so that a certain space is formed between the mixing bowl 535 and the mixing block 534. When the liquid flows into the mixing block 534, the mixing hole 535 is rotated, and the liquid is passed through the mixing hole 535, and the mixture is easily mixed through the process. In the foregoing description, the shape of the mixing bowl 535 is referred to as a ball shape, but it is needless to say that the mixing bowl 535 may be modified in various ways as long as it does not disturb the discharge of liquid.

The lower part of the mixing block 534 is provided with a concentration measuring sensor 536 for measuring the concentration of the cleaning agent in the liquid which is moved through the mixing block 534 and a concentration measuring sensor 536 for measuring the concentration of the detergent, Closing amount controller for controlling the opening / closing amount of the valve 521 and the water discharge valve 522 in a differential manner. That is, the opening / closing amount controller measures the concentration of the cleaning agent in the mixed liquid, which is moved through the mixing block 534 through the concentration measuring sensor 536, and supplies the cleaning agent discharge valve 521 And the water discharge valve 522 are controlled.

As a method of concentration measurement, a method using a probe by chemical method may be easily used, but it is difficult to measure a rapid concentration change in this method. Alternatively, the change in concentration can be measured by irradiating a color wave such as an ultrasonic wave or an infrared ray or an ultraviolet ray. That is, the physical properties of water and cleaning agent are different, and the mixed solution has a separate physical property. By utilizing this property, it is possible to measure the time of reflection or transmission by emitting ultrasonic waves, or to measure the color which is discolored by infrared ray or ultraviolet rays The concentration can be determined by measuring. Of course, it is of course possible to apply various known methods of measuring the concentrations of liquid and gas mixtures.

By controlling the opening / closing amount of the cleaning agent discharge valve (521) and the water discharge valve (522) in a differential manner through the opening / closing controller according to the measured value of the cleaning solution concentration, the amount of the cleaning agent or water discharged is controlled, .

At this time, on one side of the water discharge pipe 532 and the cleaning agent discharge pipe 531 of the Y pipe 530, an air discharge pipe 537 through which the inside is extended extends obliquely toward the inner space of the tank. The air discharge pipe 537 discharges a small amount of liquid and air to the cleaning liquid tank 500 side from the cleaning device side in the liquid spraying state. However, when backflow occurs due to sudden stop of the supply of the liquid or the like, the liquid remaining in the Y pipe 530 is discharged through the air discharge pipe 537 together with the residual air in the inner space of the cleaning liquid tank 500 (538). ≪ / RTI >

The discharge passage 538 is connected to the water storage part 511 of the cleaning liquid tank 500 and the cleaning agent storage part 512 when the discharge passage 538 is generated in a position close to the cleaning agent discharge valve 521 or the water discharge valve 522 However, since the two liquids have already been mixed, it is ambiguous to use them for reuse because of differences in concentration of the mixture and rancidity. Therefore, a separate mixture storage space is formed in the inner space of the auxiliary tank 800 and discharged to the room through the discharge passage 538 extending to the mixture storage space, or the discharge passage 538 is taken out to the outside and discarded to the outside It is also possible.

Of course, a part of the liquid to be originally injected may flow through the inclined surface, but the amount thereof is not large enough to maintain sufficient injection pressure or injection amount.

Next, the Y pipe 530 is provided with a first receiving pipe 610 extending from one side between the mixing block 534 and the inflow pipe 210 and connected to the first connecting portion near the inflow pipe 210, A second receiving pipe 620 extending from one side of the first receiving pipe 610 and connected to a second connecting portion near the inflow pipe 210 and a second receiving pipe 620 extending from one side of the second receiving pipe 620, A third receiving pipe 630 connected to a third connecting portion near the first connecting pipe 210 and a second receiving pipe 630 connected to the first connecting pipe 610 and the second connecting pipe 630, And a valve 640. The feedback module 600 is coupled to the peripheral portion of the feedback check valve 640 and includes first, second and third receiving tubes 610 and 620 630 and 630 according to the concentrations measured by the auxiliary concentration measuring sensor 641 and the auxiliary concentration measuring sensor 641 measuring the concentrations of the first to third receiving pipes 610, Differential Controlled Blood It characterized in that it further comprises a back controller.

The feedback module 600 using the plurality of receiving tubes may be influenced by the cleaning agent and is required when a uniform mixture is required at a specific mixing ratio or when the user needs to change the concentration rapidly. So that the washing solution mixture can be rapidly and uniformly produced at a desired concentration. The first receiving pipe 610 is connected to the first connecting portion extending from one side between the mixing block 534 and the inflow pipe 210 and near the inflow pipe 210. The receiver tube forms one independent receptacle through two feedback check valves 640 located at both ends (extension start and end).

The second receiving pipe 620 is connected to a second connecting portion extending from one side of the first receiving pipe 610 and adjacent to the inflow pipe 210. Finally, 2 receiving pipe 620 and connected to the third connecting portion near the inflow pipe 210. [ Both of these are located at both ends of the two feedback check valves 640. That is, the mixture of the first introduced cleaning agent and water is primarily stored in the innermost third storage tube 630, the next introduced mixture is stored in the second storage tube 620, And stored in the first storage tube 610 in order. Each of the receiving pipes further includes an auxiliary concentration measuring sensor 641 for measuring the concentration, so that the concentration of the mixture stored in each receiving pipe can be confirmed.

Thus, when the user controls to spray a cleaning liquid at a specific concentration, the mixture of cleaning agent and water initially discharged and mixed may slightly differ from the concentration requested by the user. As described above, when the concentration of the cleaning agent is too high due to the characteristics of the pipe 200 composed of metal or synthetic resin, it may cause corrosion of the pipe 200. Thus, in order to more accurately adjust the concentration of the cleaning agent, the concentration of the mixture is discharged at a constant rate through the operation of adjusting the concentration using a three-stage receiving tube so as to be constantly discharged from the initial concentration of the discharged mixture.

That is, the mixture is divided into three stages, and the mixture is received in each of the receiving tubes, and each of the receiving tubes is closed with the feedback check valve 640. Next, when the concentration is measured by the auxiliary concentration measuring sensor 641 in each receiving tube, the feedback controller combines these concentrations to control the feedback check valve 640 to match the concentration of the mixture requested by the user, Mix the mixture and adjust the concentration. Through this process, the concentration of the exhaled mixture can be released from the beginning to the specific concentration specified by the user through a continuous and fast preparation time.

Accordingly, the user can easily carry it, monitor the discharge condition of the cleaning agent for cleaning the pipe 200, recognize the concentration of the cleaning agent in the water from the beginning to the end of cleaning, It is possible to perform the cleaning of the pipe 200 having high efficiency because the pipe 200 is uniformly discharged at a predetermined concentration.

Although the construction and operation of the portable pipe cleaning assembly according to the present invention have been described above and illustrated in the drawings, the present invention is not limited to the above description and drawings, It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention.
