Description

FLEXIBLE WIRE FOR CLEANING SCALE FORMED IN PIPE}

The present invention relates to a flexible wire for removing the pipe scale, more specifically, the pipe scale is applied to the pipe descaling device in a structure that can be properly connected to the length of the pipe to be cleaned to effectively remove the scale formed in the inside of the pipe It relates to a flexible wire for removal.

In general, pipes installed for the flow of fluids, including hot water, have a scale formed on the inner surface of the pipe due to corrosion or oxidation of various substances in the fluid, etc. do.

If the scale is formed on the inner surface of the pipe, the inner diameter of the pipe is gradually narrowed, which causes the flow path to be reduced, thereby preventing the smooth flow of the fluid in the pipe. If the flow rate of the gas is severely disturbed, the pressure of the fluid increases, which may increase the possibility of adversely affecting the pipe.

Therefore, the scale formed inside the pipe should be removed only by applying an appropriate method or means. Examples include a method of injecting a chemical into the pipe and reacting with the scale to remove the scale. In case of descaling, highly toxic chemicals should be used depending on the components of the scale, or additional cleaning should be performed by supplying the washing water for cleaning chemicals in the pipe after the scale is removed by injecting chemicals. It is likely to be accompanied by environmental pollution.

In consideration of the disadvantages of using such chemicals, another example is a method in which a method of removing the scale inside the pipe by rotating a flexible wire by an electric motor is applied.

1 is a view for explaining a pipe descaling apparatus according to a conventional example.

Referring to the drawings, the pipe descaling device includes an electric motor 10 for generating a rotational force, and the electric motor 10 is provided with a hollow shaft 14 in the form of a pipe through which the flexible wire 12 passes. You lose.

At the rear of the electric motor 10, a wire housing 16 for accommodating the flexible wire 12 to a predetermined length is disposed, and the front / side of the electric motor 10 is drawn out through the hollow shaft 14. A wire collect chuk 18 for fixing the flexible wire 12 to be introduced is fixedly disposed.

The electric motor 10 is coupled to allow the reciprocating movement within the range of the guide member 24 formed on the base 22 via the motor bracket 20 of a predetermined shape.

Accordingly, assuming that the scale 28) is formed inside the pipe 26 in FIG. 1, the wire 28 is first drawn out from the wire housing 16 through the hollow shaft 14 and the wire fixing chuck 18. The front end of the flexible wire 12 is introduced into the inlet of the pipe 26.

In that state, when the flexible wire 12 is fixed by the wire fixing chuck 18 and the electric motor 10 is rotated, the wire fixing chuck 18 and the wire fixing chuck 18 The fixed flexible wire 12 is also rotated so that its tip removes the scale 28 formed on its inner surface while forming a wave in the pipe 26.

When the descaling process of the predetermined length is completed by the above process, the electric motor 10 is stopped, and then the fixing of the flexible wire 12 by the wire fixing chuck 18 is released to remove the flexible wire 12. It is again drawn out by a predetermined length so as to enter the pipe 26. Thereafter, when the flexible wire 12 is fixed again by the wire fixing shaft 18 and the electric motor 10 is operated again, the wave action of the flexible wire 12 is performed in the same manner as described above. The scale 28 formed on the inner surface of the pipe 26 is removed.

Therefore, the process of repeating the withdrawal and the wave action of the flexible wire 12 is repeated to remove the scale 28 formed on the inner surface of the pipe 26.

Here, the tubing 26 is typically linear but usually connected by a 'b'-shaped connector or a' U'-shaped connector, if necessary, so that for the flexible wire 12 Not only in the linear part of the pipe 26 but also in the part of the '-'- shaped connector or the' U'-shaped connector should be made in a form capable of smooth entry and wave action.

FIG. 2 is a schematic view for explaining the flexible wire 12 according to the conventional example shown in FIG. 1.

The flexible wire 12 shown in the drawing forms a smooth wave inside the pipe 26 while also ensuring a bending property favorable for entry even in the bent portion of the pipe 26 elastic wire 12a in the spring form And a head 12b which is formed at the tip of the elastic wire 12a and is variously formed in an advantageous shape in the bent portion of the pipe 26.

Thus, in the case of the flexible wire 12 shown in FIG. 2, the '12'-shaped connector or the' U'-shaped connector as well as the linear portion of the pipe 26 by the head 12b. Smooth entry and wave action are possible in the part of.

However, the flexible wire 12 according to the conventional example shown in FIG. 2 is typically provided in the wire housing 16 shown in FIG. 1 with a constant length irrespective of the entire length of the pipe 26. As a result, when the length of the flexible wire 12 is short compared to the entire length of the pipe 26, it is disadvantageous to descale the entire length of the pipe 26.

In addition, since the flexible wire 12 has to remove the scale 28 formed on the inner surface of the pipe 26 only by the wave formed by the rotation of the electric motor 10, the flexible wire 12 is It is highly likely that the scale 28 of the portion that is not in contact will not be removed.

Accordingly, the present invention has been made in view of the above-described prior art, and can be used by connecting to fit the entire length of the pipe, and a scale removing brush is formed to effectively remove the scale of the pipe inner surface. The purpose is to provide a flexible wire for removal.

In order to achieve the above object, according to a preferred embodiment of the present invention, the flexible wire included in the pipe descaling device to remove the scale formed in the pipe in conjunction with the rotation of the electric motor, the rotation of the electric motor The core wire coupled to the elastic spring of a predetermined length for removing the scale in the pipe while rotating by, and the brush is attached to the elastic spring and the brush for removing the scale of the pipe while being disposed inside the elastic spring. A flexible wire for removing a pipe scale is formed on both ends of the embedded elastic spring and includes first and second connection ends for connection with other elastic springs.

Preferably, according to the present invention, the core wire is formed by crossing a plurality of steel wires or by forming a flexible synthetic resin.

In addition, the first connection end is formed with a connection protrusion for connecting with the second connection end of the other elastic wire according to the length of the pipe and elastically in and out of the front center of the connection protrusion is connected to the other elastic wire Fixing protrusions are formed for the fixation function.

Correspondingly, the second connecting end is formed with a connecting groove corresponding to the connecting protrusion of the first connecting end so as to be connected to the first connecting end of the other elastic wire, and the center of the connecting groove is the first connecting end. The fixing protrusion receiving groove is formed to receive the fixing protrusion of.

According to the flexible wire for removing the scale of the pipe according to the present invention, the elastic wire is connected to the electric motor of the pipe descaling device while the elastic wire having a brush-coupled core wire is connected and used along the length of the pipe. Since the scale formed inside the pipe is removed by the wave action generated by the rotation and the brushing action by the brush, it is possible to remove the scale more effectively than the case of removing the scale of the pipe only by the elastic wire.
