[0001] The Pipe Inner Scale Remove Tool [0002]

The present invention relates to a piping scale removing apparatus for removing scales and foreign matter inside a hollow pipe or a large diameter pipe.

Generally, a pipe serves to guide a fluid including water, and is installed in a buried form in a floor or a wall of a building.

If the piping is used for a long period of time, the inner wall of the piping is oxidized and corroded or various kinds of foreign substances are trapped, resulting in a scale. Such a scale becomes solid after a long time, and the channel of the piping becomes narrow.

If the flow path of the piping is narrowed due to the scale, there is a problem that the fluid is not smoothly moved and thus the function of the piping can not be exhibited. In addition, the piping can not withstand the movement pressure of the fluid Lt; / RTI >

In addition, the piping has a narrow width and a long length. In general, there is a method of cleaning the inside of the piping by filling the entire amount with the cleaning liquid. However, this has the problem that the deposit can be removed only in a small- 10-2011-0092656, Korean Patent Laid-Open Publication No. 10-1999-0051137, a drum was installed outside the pipe, and a helical wire was installed on the drum. The spiral wire removed the scale inside the pipe, It is difficult to apply to a medium-diameter pipe or a large-diameter pipe other than a caliber pipe.

In addition, as described in Korean Patent No. 10-0843963 and Korean Patent Laid-Open Publication No. 10-2015-0010480, it is possible to remove the scale inside the piping, but it is difficult to remove the scale hardened inside the piping And a scale and foreign matter can not be removed from a part of the metal pipe.

Further, there is a problem in that scale and foreign matter can not be removed from a part of the metal pipe.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

For reference, the same components as those of the prior art of the present invention will be described with reference to the above-mentioned prior arts, and a detailed description thereof will be omitted.

1 is a schematic diagram of a piping descaler according to a preferred embodiment of the present invention;

1, the piping scale removing apparatus according to the present invention includes a drum 3 installed in a pipe 1, a sand paper 4 attached to an outer surface of the drum 3, And a driving unit M connected to the shaft 2 and providing a driving force to the drum 3, wherein the drum 2 is connected to the drum 3, 3) is formed with a threaded groove and a thread is formed on an outer surface of the shaft (2) so that the drum (3) can be changed according to the inner diameter of the pipe (1) ) Can be changed according to the length of the pipe (1).

The piping 1 is a passage through which a fluid is mainly installed in the form of a buried floor in a floor or a wall of a building.

The pipe 1 is preferably a medium diameter pipe or a large diameter pipe, and the pipe 1 is preferably made of a metal material.

A drum (3) is installed inside the pipe (1) to remove scale.

The drum 3 has a conical shape. Thus, even if scales and foreign substances are accumulated in the center of the pipe 1, the pipe 1 is smoothly introduced into the pipe 1.

The drum 3 is formed with a threaded groove.

The grooves are formed inwardly from the rear surface of the drum 3.

A shaft 2 to be described later is provided in the groove so that the shaft 3 moves in the forward or backward direction while the drum 3 is rotated by a shaft 2 of a shaft 2 to be described later.

It is preferable that the drum 3 can be used in accordance with the inner diameter of the pipe 1. [

A sand paper (abrasive paper) 4 is attached to the outer surface of the drum 3.

The sand paper 4 grinds scales and foreign substances hard pressed on the inner surface of the pipe 1 and rubs rust generated due to scales and foreign matter to thereby remove the inner surface of the pipe 1 So as to smooth the movement of the fluid.

A shaft (2) is provided behind the drum (3).

The shaft (2) is in the form of a rod having threads formed on its outer surface.

The shaft 2 is installed in the groove of the drum 3 so as to be assembled and disassembled so as to transmit a driving force of a driving part M to be described later to the drum 3.

The shaft 2 is preferably a lead screw. Thus, it is easy to assemble and disassemble the drum 3 and the shaft 2, thereby facilitating the replacement of the drum 3.

A first belt pulley (7-1) is provided on the rear side of the shaft (2).

In the first belt pulley 7-1, a hollow is formed so that the shaft 2 is installed, and a thread is formed in the hollow.

Thus, the shaft 2 is installed in the first belt pulley 7-1 so as to be assembled and disassembled, and is installed to be movable in the front-rear direction of the pipe 1. Thus, the shaft 2 is additionally provided at the length of the pipe 1, so that the inside of the 6m pipe can be easily cleaned.

The first belt pulley 7-1 is connected to a second belt pulley 7-2 of a drive unit M to be described later by a belt 8. [

A driving unit M is connected to the shaft 2.

The driving unit M is connected to the shaft 2 to provide a driving force to the drum 3. The drum 2 is rotated by the driving force of the driving portion M to move the drum 3 to the internal position of the pipe 1 when the shaft 2 moves in all directions, The shaft 2 is moved in the backward direction after the scale is removed so that the shaft 2 is rotated (in the opposite direction) by the rotation of the shaft 2, (3) and also to the outside of the pipe (1).

A second belt pulley 7-2 is installed on the driving shaft 5 of the driving unit M.

The second belt pulley 7-2 is connected to the first belt pulley 7-1 by a belt 8 so as to transmit the driving force of the driving unit M to the drum 3. [

It is preferable that the driving unit M is a motor.

The belt pulley 7-2 is connected to a belt pulley 7-1 provided on the shaft 2 by a belt 8 so as to transmit the driving force of the motor M to the drum 3. [

Hereinafter, the operation of the present embodiment having the above-described configuration will be described.

The drum 3 is assembled in front of the shaft 2 and the first belt pulley 7-1 is assembled to the rear of the shaft 2. [ And the second belt pulley 7-2 is assembled to the driving shaft 5 of the driving portion M. [

The first belt pulley 7-1 and the second belt pulley 7-2 are connected by a belt 8.

So that the drum 3 is positioned inside the pipe 1.

The driving unit M is operated to rotate the shaft 2 in the advancing direction (forward direction of the pipe) so that the drum 3 is inserted into the pipe 1 and the scales and the foreign substances in the pipe 1 are removed .

The shaft 2 is rotated in the direction opposite to the advancing direction (rear direction of the pipe) so that the drum 3 comes out of the pipe 1 and the pipe 1 is separated from the pipe.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims, And can be carried out by modification.

As described above, the piping scale removing apparatus according to the present invention is particularly suitable for a piping scale removing apparatus for removing scales and foreign matter inside a medium diameter or large diameter (100A) metallic pipe of power plants and industrial facilities.
