Description

TECHNICAL FIELD [0001] The present invention relates to a pipe cleaning system and a pipe cleaning method using the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping cleaning system, and more particularly, to a piping cleaning system for cleaning the inside of a pipe in both directions to remove foreign matter such as scales deposited on an inner wall of the piping.

Generally, a pipe serves as a passage for guiding and moving water or other fluid to a predetermined place, and is installed mainly in a form embedded in the inside of the building, the floor, or the wall. Such pipes are oxidized and corroded at the time of long-term use, and various foreign substances adhere to the inner wall surface to generate a scale. Such a scale is solidified over a long period of time and causes the pipe to be narrowed.

As the flow path cross-sectional area of the piping becomes smaller due to the scale as described above, the movement of the fluid is not smooth and the piping function as designed can not be performed. In severe cases, the piping may be damaged due to the movement pressure of the fluid.

Therefore, when a large amount of scale is generated in the piping, it is necessary to remove the scale and perform a normal role as the piping. Various techniques related to the scale removal in the piping are disclosed.

In such a conventional technique, there has been proposed a method of cleaning the inside of a pipe by discharging strong water pressure washing water into the inside of the pipe, or removing the scale inside the pipe by using a compression wave together with the water pressure. Recently, A method of cleaning the inside of the pipe by injecting compressed air is also used.

However, as the length of the pipe becomes longer, the efficiency of the pipe decreases. This is because the water pressure of the washing water injected into one side of the pipe gradually decreases in the course of the process, It falls.

In addition, although the water pressure of the washing water injected into the pipe may be increased in order to improve the cleaning efficiency of the pipe, in this case, there is a possibility that the pipe may be damaged due to the strong water pressure washing water. In the case of the deteriorated pipe, There is a problem that can happen easily.

In order to solve such a problem, a method of cleaning the inside of a pipe by using a cleaning ball that injects a cleaning ball into the inside of the pipe is also disclosed. In this conventional technique, the cleaning balls are moved inside the pipe while scraping foreign materials such as scales and discharged together with the cleaning water. The cleaning balls are injected into one end of the pipe and moved to the other end.

However, in the conventional technique using such a cleaning ball, the moving speed of the cleaning ball is lowered toward the end of the pipe, and the cleaning rate varies depending on the position inside the pipe.

The valve units V3 to V6 include first to fourth valves. Wherein i) the first valve (V3) is connected to the first valve (V2) of the pipe (15) via the first flow path (F1), the wash water and the compressed air supplied from the wash water supply part (200) And ii) the second valve V4 allows the washing water and the compressed air supplied from the washing water supply part 200 and the compressed air supply part 300 to flow to the second flow path F2 Iii) the third valve (V5) allows the washing water discharged through the second end (15b) of the pipe (15) to move to the second end (15b) of the pipe Iv) the fourth valve V6 allows the washing water discharged through the first end 15a of the pipe 15 to be discharged to the washing unit discharging unit 400 through the flow path F3, And is selectively discharged to the cleaning unit discharge unit 400 through the four flow paths F4.

That is, the valve units V3 to V6 are appropriately opened and closed to control the flow of the washing water and the compressed air. For example, the washing water and the compressed air supplied from the washing water supplying unit 200 and the compressed air supplying unit 300 The first valve V3 of the valve units V3 through V6 is opened and the second valve V4 is opened to allow the first valve 15 to be supplied to the first end 15a of the pipe 15 via the first flow path F1. And the fourth valve (V6) are respectively shielded. The washing water and the compressed air can be guided to the first end 15a of the pipe 15 through the first flow path F1 without moving through the second flow path F2 and the fourth flow path F4 .

On the other hand, the flow control unit 100 is provided with fluid operation units 150 and 160. The fluid operation units 150 and 160 are installed to be connected to at least one of the first end 15a or the second end 15b of the pipe 15 to operate the wash water and the compressed air.

More specifically, the bubble generating unit 156 is provided in the fluid operation units 150 and 160 so that fine bubbles are generated from the washing water. The bubble generating unit 156 generates fine bubbles from the washing water, and generates negative ions by the fine bubbles, thereby activating the sterilizing function inside the pipe 15.

The specific shape of the bubble generating portion 156 is shown in Figs. 2 and 3. Fig. As shown in the figure, the bubble generating unit 156 has an opening 159 through which the washing water is supplied, and a plurality of bubble forming holes 158 are formed on the outer surface of the bubble generating unit 156 to generate minute bubbles. do.

4A is a cross-sectional view of a portion of the outer surface of the bubble generator 156. As shown in FIG. 4A, the bubble generator 156 has a plurality of bubble- A fluid flow space S is formed between the layers of the bubble forming holes 158 formed by the layers 158a and 158b and having different heights.

Accordingly, the washing water flowing into the bubble generating portion 156 passes through the bubble forming hole 158a in the upper layer through the bubble forming hole 158b in the lower layer relatively, and the microbubbles are more actively generated . 4 (a), the bubbling hole 158 is formed of two layers, but it may be three or more layers.

At this time, the bubble forming holes 158 formed at different heights in the bubble generating portion 156 are preferably formed to be shifted so that the opening directions do not coincide with each other. This is because the contact between the cleaning water and the inner surface of the bubble generating hole 158 becomes larger when the open directions of the bubble forming holes 158 forming the different layers are shifted from each other, As shown in FIG.

Meanwhile, as shown in FIG. 4 (b), the bubbling hole 158 may be formed in an oblique direction. This is to allow the washing water in which minute bubbles are generated to flow smoothly in the traveling direction (left side).

2 and 5, the fluid operation units 150 and 160 are provided with vortex generators 152 adjacent to the bubble generator 156, so that the washing water passing through the bubble generator 156 is vortexed . The vortex generating unit 152 causes the washing water containing minute bubbles to vortex so as to improve the pipe cleaning performance by the vortex and increase the dissolution rate of the fine bubbles.

Particularly, when the vapors generated by the vortex generating unit 152 generates a vortex, the momentum bubbles contained in the washing water collide with the inner wall and are blown, and ultrasound waves are generated in the process. Ultrasonic waves generated by the microbubbles further improve the cleaning effect. In particular, the liquid pressure of the cleaning liquid is shocked by the ultrasonic waves, so that the scale and the molecular structure of the organic material fixed on the inner surface of the pipe are cut off.

The vortex generating unit 152 is rotated according to the flow of washing water moving at a high speed together with the compressed air. To this end, the vortex generating unit 152 includes a rotating shaft (not shown) extending in a direction parallel to the flowing direction of the washing water ).

Meanwhile, the pipe cleaning system may include a cleaning ball 500. The cleaning ball 500 removes foreign matter such as scale while moving inside the pipe 15 together with the cleaning water and the compressed air. More specifically, the cleaning ball 500 is connected to the pipe 15 together with the cleaning water, And is discharged into the second end 15b or the first end 15a of the pipe 15 through the first end 15a or the second end 15b of the pipe 15.

At this time, as shown in FIG. 7, a cleaning protrusion 520 protrudes from the outer circumferential surface 510 of the cleaning ball 500. The cleaning protrusion 520 may be formed by protruding a plurality of protrusions on the outer circumferential surface of the cleaning ball 500 as shown in FIG. So that it can move more smoothly inside the pipe 15. This is shown in Fig.

The cleaning ball 500 may be provided in the interior 171 'of the ball housing 170. 6, a ball housing 170 is provided at one side of the flow control unit 100 and the cleaning ball 500 is inserted into the pipe 15 through the ball housing 170 So that the cleaning ball 500 can be prevented from being introduced into the flow path control unit 100.

6, reference numeral 172 denotes an inlet and an outlet through which the cleaning ball 500 is input and output, reference numeral 173 denotes a first connection unit connected to the fluid operation unit 150, And a second connection portion connected to the first end 15a.

Although not shown, a sensor unit is provided in the ball housing 170 to measure a moving speed or a moving time of the cleaning ball 500. The sensor unit may be configured to measure the movement time of the cleaning ball 500 in the pipe 15 and estimate the length of the inside of the pipe 15 from the velocity of the predetermined cleaning ball 500 or ii) The moving speed of the cleaning ball 500 may be calculated from the moving time of the cleaning blade 500 and the length of the pipe 15 already known. To this end, in the present embodiment, the sensor unit is provided in a pair of ball housings 170 provided in the flow path control unit 100, respectively.

Hereinafter, a piping cleaning method using the piping cleaning system according to the present invention will be described in detail with reference to the drawings.

FIG. 9 is a structural view showing a process of washing the inside of a pipe 15 in a first direction using the embodiment of the present invention. FIG. 10 shows the inside of the pipe 15 in a second direction As shown in FIG.

Referring to FIG. 9, when the pipe cleaning system according to the embodiment of the present invention is operated, the pump of the wash water supply unit 200 operates to supply the wash water to the flow control unit 100 through the wash water supply pipe 210, The flow path control unit 100 guides the washing water to flow into the first end 15a of the pipe 15 (arrow ③). At this time,

More precisely, among the valve units V3 to V6 provided in the flow path control unit 100, the first valve V3 is opened and the second valve V4 is blocked, The washing water is moved along the first flow path F1. At the same time, the fourth valve (V6) among the valve units (V3 to V6) is shielded so that the washing water can be prevented from flowing out toward the washing unit discharge unit (400).

When the washing water flows into the flow path control unit 100, the compressed air supply unit 300 operates to supply the compressed air into the flow path control unit 100. The compressed air flows through the flow path control unit 100, The washing water is mixed with the washing water, and the washing water can be smoothly flowed into the pipe 15 to provide a driving force.

At this time, the washing water and the compressed air flow into the fluid operation unit provided at one side of the flow path control unit 100, and minute bubbles are generated through the fluid operation unit. More specifically, minute bubbles are generated from the washing water in the course of passing through the bubble generating unit 156 provided in the fluid operating unit, and the generated minute bubbles are contained in the washing water having a high dissolving rate while passing through the vortex generating unit 152 And then moved together.

A ball housing 170 is provided at one side of the fluid operation unit and the cleaning ball 500 located inside the ball housing 170 moves together with the cleaning water to move the first end 15a (Arrow ④).

The cleaning ball 500 moves along with the cleaning water to remove foreign matter such as scale adhering to the inner wall of the pipe 15. (Arrow ⑤) At this time, as described above, the cleaning water is generated by the minute bubbles contained in the cleaning water And also an action of sterilizing the pipe 15 occurs.

The washing water and the washing ball 500 move along the pipe 15 and are discharged through the second end 15b of the pipe 15 And moves toward the control unit 100.

At this time, the washing water flows into the flow path control unit 100, and the washing ball 500 stays inside the ball housing 170 because the washing ball 500 is in fluid communication with the ball housing 170 And is hooked on the operation units 150 and 160.

The washing water flowing into the flow control unit 100 moves along the third flow path F3 (arrow ⑦) and is discharged through the washing unit discharging unit 400 (arrow ⑧). This is because the second unit of the valve units V3 to V6 is shielded and the third valve V5 is opened, so that the washing water moves along the third flow path F3.

Since the washing water is naturally discharged to the outside after one washing, the pressure inside the pipe 15 can be prevented from being excessively increased.

Next, a second cleaning step will be described with reference to FIG. FIG. 10 shows the reverse cleaning process of the preceding cleaning process. That is, the pipe cleaning method using the pipe cleaning system according to the present invention is characterized in that the pipe is cleaned continuously in two directions, and the pipe cleaning rate can be further improved through the continuous reverse cleaning.

In this case, among the valve units V3 to V6 of the flow control unit 100, the first valve V3 and the third valve V5 are shielded, and the second valve V4 and the fourth valve V6 are closed And the flow of the wash water in the opposite direction to that of the previous flow is generated.

In this process, the discharging step of discharging the washing water is continuously performed.

At this time, since the cleaning ball 500 is in a state of being seated in the ball housing 170 provided at the start and the ball housing 170 at the start in the previous first cleaning step, it is unnecessary to prepare the new cleaning ball 500 A second cleaning step can be performed.

Meanwhile, since the pair of ball housings 170 are equipped with the sensor unit, the moving time of the cleaning ball 500 can be checked in the reciprocating process of the cleaning ball 500. If the length of the pipe 15 is known, the speed of the cleaning ball 500 can be calculated and the sectional area of the pipe 15, the length of the pipe 15, the amount of the scale inside the pipe 15 The washing water supply unit 200 and the compressed air supply unit 300 are controlled so as to increase the speed of the washing ball 500 so as to increase the flow rate of the washing water, Or less. Such a series of control processes can be automatically controlled by the control unit.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.
