Description

[0001] SCALE REMOVING UNIT FOR A FLEXIBLE PIPE FOR FLEXIBLE PIPING [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scale removal unit, and more particularly, to a scale removal unit for flexible piping capable of removing scale inside a flexible pipe including a flexible material.

Conventionally, scales or rusts accumulated in piping such as apartments, houses, etc. have been removed by using chemical methods or physical methods, but this has been disadvantageous in that time and cost are increased.

Recently, as shown in FIG. 1, a technique has been introduced in which an induction coil, which is supplied with electric current and induces an electromagnetic field, is formed along a pipe to prevent or remove the accumulation of deposits accumulated in the pipe. Particularly, in the case of such a technique, it is possible to prevent a harmful problem to the human body from being caused when the scale is removed by the conventional chemical method, and it is possible to prevent the increase of the construction cost and the construction period when the scale is removed by the physical method. Furthermore, there is an advantage that it is possible to omit the problem of periodically repeating the operation for removing the scale.

However, in the case of the scale removal unit through electromagnetic induction developed so far, the removal unit can be locally installed only in a part of the pipe, and the removal efficiency is significantly reduced as the length of the pipe becomes longer. Accordingly, in order to increase the removal efficiency, the number of windings of the coils must be increased or a plurality of removal units must be disposed on the piping. In this case, the overall piping design becomes complicated and the unit cost of installation of the removal unit increases .

Korean Patent Publication No. 10-2015-0050087

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a scale removal unit capable of improving scale removal efficiency and simplifying piping design with a relatively simple structure.

The scale removing unit according to an embodiment of the present invention for realizing the object of the present invention described above is fixed to a flexible pipe extending in a coil shape so as to adjoin each other with a side surface including a flexible material and includes a coil portion and a current supplying portion. The coil portion extends in a direction crossing the flexible pipe and is wound on the outside of the flexible pipe. The current supply part is electrically connected to the coil part to supply current to the coil part.

In one embodiment, the fixing device may further include a fixing frame disposed between the flexible pipe and the coil part in a direction parallel to the direction in which the coil part is wound, for fixing one side of the overlapped flexible pipe.

In one embodiment, the fixed frame may include a plurality of openings to allow the flexible tubing to be secured to each of the openings.

In one embodiment, the fixed frame may be a rectangular block extending in a direction crossing the extending direction of the flexible pipe passing through the openings.

In one embodiment, the coil portion may be wound along an outer surface of the fixed frame in a direction crossing the extending direction of the flexible pipe.

In one embodiment, the coil portion may be wound a plurality of turns on the outside of the flexible pipe.

In one embodiment, the flexible tubing may be a hose used inside the water purifier.

According to the embodiments of the present invention, since the electromagnetic field is induced by supplying current to one side of the flexible pipe superimposed in the form of a coil, the area of the pipe through which the electromagnetic field is induced is increased, .

In this case, the fixing frame may further include a fixing frame, which fixes the flexible pipe extending in the form of a coil, and at the same time, the coil is wound on the outside so that an electromagnetic field can be induced.

Particularly, since the extending direction of the fixed frame and the winding direction of the coil portion are formed in the direction crossing the flexible pipe, it is possible to fix the flexible pipe more effectively and more uniformly to the flexible pipe The electromagnetic field can be applied, and the scale removing effect can be improved.

Furthermore, since a plurality of the coil portions can be fixed to the side portions of the flexible pipe overlapped in the coil shape, the scale removing effect can be further uniformly improved while further improving the fixing force of the flexible pipe.

2 is a perspective view showing a state in which a scale removal unit according to an embodiment of the present invention is installed in a flexible pipe.

Referring to FIG. 2, the scale removal unit 200 according to the present embodiment is applied to a flexible pipe 100 wound and extended to each other in a coil form.

2, when the flexible pipe 100 includes a flexible material such as a polymer material and has a flexible nature, the flexible pipe 100 is entirely divided into a first direction X, And extend in a coil shape so as to overlap with each other in a plurality of layers in the first direction (X).

In this case, it is preferable that the flexible pipe 100 extends in the form of a coil only at a portion where the descaling unit 200 is coupled, because it is inefficient for the entire pipe to extend in the form of a coil as shown in FIG.

In FIG. 2, the flexible pipe 100 rotates five times, and the coil shape overlapped with each other is exemplified. However, the number of superposed rotations of the flexible pipe 100 and the width of the coil can be variously changed according to design It is self-evident.

Further, the flexible pipe 100 may be, for example, a pipe installed in a water purifier or the like, but is not limited thereto and may be applied to various devices in which water flows.

The descaling unit 200 includes a fixed frame 210, a coil part 220, and a current supply part 230.

The fixed frame 210 fixes the flexible pipe 100 on one side of the flexible pipe 100 superimposed on each other in the form of a coil.

In this case, the fixed frame 210 may have a rectangular block shape extending in the first direction X and having a plurality of openings. Thus, the flexible pipe 100 passes through each of the plurality of openings, so that the flexible pipe 100 passes through the opening and intersects the extending direction of the fixed frame 210. [

As described above, the fixed frame 210 includes an opening, and the flexible pipe 100 passing through the opening can be fixed at one side, so that the shape of the flexible pipe 100 as a whole can be kept constant.

However, since the fixed frame 210 is located on one side only, the coil shape of the flexible pipe 100 may be deformed due to a difference in fixing force. In order to prevent this, the fixed frame 210 is fixed A separate adhesive member may be formed on the outer surface of the flexible pipe 100 except for the side portions of the flexible pipe 100 to improve the adhesion and fixing force with the adjacent flexible pipe 100.

The coil part 220 is wound along the outer surface of the fixed frame 210. That is, the coil part 220 is wound along the outside of the flexible pipe 100 in a direction parallel to the first direction X in which the fixed frame 210 extends, and the inner part of the coil part 200 The flexible pipe 100 is stacked in a plurality of layers.

Accordingly, the winding direction of the coil part 220 is in a direction crossing the extending direction of the flexible pipe 100, and the coil part 220 is formed of a flexible pipe 100 ).

Accordingly, the water passing through the inside of the flexible pipe 100 is uniformly passed through the inside of the coil part 220 periodically and at a position overlapped with the coil shape.

That is, the water passing through the inside of the flexible pipe 100 passes through the electromagnetic field provided by the coil part 220 more uniformly and repeatedly.

The current supply part 230 is electrically connected to the coil part 220 to supply current to the coil part 220. Accordingly, an electromagnetic field is formed in the coil part 220.

On the other hand, the scale formed in the inside of the pipe is formed by the calcium carbonate and the carbonic acid solution which are formed by the combination of the calcium and the bicarbonate in the water, and by the Lorentz force, The generation of carbon dioxide is suppressed and the accumulated scale inside the pipe is also removed by generating carbon dioxide.

Particularly, in this embodiment, since the electromagnetic field is induced at one side of the flexible pipe 100 and the area where the electromagnetic field is relatively increased, the water passing through the inside of the flexible pipe 100 is repeatedly moved to the same position The force of the Lorentz by the electromagnetic field is applied, and the scale can be removed more uniformly and effectively.

3 is a perspective view showing a state in which a scale removal unit according to another embodiment of the present invention is installed in a flexible pipe.

The scale removal unit according to the present embodiment is the same as the scale removal unit 200 described with reference to FIG. 2, except for the number fixed on the flexible pipe 100, so that the same reference numerals are used, It is omitted.

Referring to FIG. 3, the scale removal unit according to the present embodiment includes a scale removal unit 200 as described with reference to FIG. 2, which is fixed to one side of the flexible pipe 100 extending in the form of a coil as a first scale removal unit The second scale removal unit 300 is additionally fixed to the other side of the flexible pipe 100. In addition,

In this case, the second scale removal unit 300 may be fixed from the first scale removal unit 200 at a predetermined distance in the circumferential direction of the flexible pipe 100 in the form of a coil, as shown in FIG. 3 And may be fixed to the opposite side of the first descale unit 200, unlike the first descale unit 200.

Further, three or more descale units may be fixed to the flexible piping 100.

3, the first scale removal unit 200 includes a first current supply unit 230 and the second scale removal unit 300 includes a second current supply unit 330, The first coil part 220 of the first descale unit 200 and the second coil part 320 of the second descale unit 300 are connected to each other in one current supply unit, Current may be supplied simultaneously.

Since the plurality of scale removal units are fixed along the circumference of the flexible pipe 100 superimposed in a coil shape in this way, the electromagnetic field can be guided more and more repeatedly because of induction of the electromagnetic field, And the removal efficiency of the scale stacked on the inside of the flexible pipe can be further improved.

4 is a perspective view showing a state in which a scale removal unit according to another embodiment of the present invention is installed in a flexible pipe.

The scale removing unit according to the present embodiment is the same as the scale removing unit described with reference to FIG. 2 except that the fixed frame 210 is omitted, and the scale removing unit described with reference to FIG. 2, They are substantially the same, so duplicate descriptions will be omitted.

Referring to FIG. 4, the descaling unit according to the present embodiment includes a coil part 420 and a current supply part 430 because a fixed frame is omitted.

The coil part 420 is wound on the outside of the flexible pipe in a direction crossing the direction in which each of the flexible pipes extends in a flexible pipe extending in the form of a coil so that the side faces adjoin each other.

In this case, the coil part 420 directly contacts the outer surface of the flexible pipe 100 and is wound on the outer surface of the flexible pipe 100. That is, as shown in FIG. 4, the coil part 420 is wound in a direction crossing or perpendicular to the direction in which each of the flexible pipes 100 extends.

The current supply unit 430 is electrically connected to the coil unit 420 and supplies current to the coil unit 420. Since the detailed description is the same as that already described with reference to FIG.

Further, a plurality of the coil part 420 may be wound outside the flexible pipe 100, which removes the fixed frames 210 and 310 from the scale removal unit of FIG. 3, As shown in Fig.

According to the embodiments of the present invention, since the electromagnetic field is induced by supplying current to one side of the flexible pipe superimposed in the form of a coil, the area of the pipe through which the electromagnetic field is induced is increased, .

In this case, the fixed frame may further include a fixed frame. The fixed frame serves to fix the flexible pipe extending in the form of a coil, and at the same time, the coil may be wound on the outside to induce an electromagnetic field.

Particularly, since the extending direction of the fixed frame and the winding direction of the coil portion are formed in the direction crossing the flexible pipe, it is possible to fix the flexible pipe more effectively and more uniformly to the flexible pipe The electromagnetic field can be applied, and the scale removing effect can be improved.

Furthermore, since a plurality of the coil portions can be fixed to the side portions of the flexible pipe overlapped in the coil shape, the scale removing effect can be further uniformly improved while further improving the fixing force of the flexible pipe.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.

The descaling unit according to the present invention has industrial applicability that can be used for scaling or rust removal of flexible piping.
