Description

The removal device of fixed substance inside wall of pipe}

The present invention relates to a device for removing rust, scale, etc. that is fixed in the pipelines such as pipes, and more specifically, to drive the fixed material removal unit of the rotating body by the rotational force of the motor, the fixed material removal unit is driven A plurality of striking plates mounted thereon are directed to a device that removes stuck material by zigzag-cutting a fixation secured to the pipe while rapidly striking the inner wall of the pipe.

In general, when a metal tube flows into a tube, the fluid reacts with the tube, and rust or scale accumulates on the inner wall of the tube, causing foreign substances to be fixed. Secured materials not only cause corrosion inside the tube, but also impede the flow of the fluid, thus locally blocking the flow of the fluid, which can lead to high pressures which can cause the flange or pipe of the seam to rupture.

Thus, there is a need for means to remove material stuck inside the tube. Foreign substances stuck inside the pipe through a long time can not be easily removed by the usual means, a means to give a strong impact is needed. Otherwise, the only way to fix rust or scale is to cut off a large portion and connect a new tube. However, a metal tube or the like is expensive, or if it is buried in the ground, labor costs will be increased. Therefore, it is economically undesirable to simply cut out the tube to which the scale and the like are fixed and weld it with a new tube.

Also, cutting out parts and connecting new tubes is not an easy process. The reason is that the newly connected pipe does not have scale such as rust, but the existing pipe will be scaled, so welding is not easy.

In addition, in the case of a pipe made of concrete or the like, it is not economically desirable to remove the portion where the scale is fixed and replace it with another one.

In general, as a method for removing a stuck substance stuck in an aging pipe, a device for removing a fixed substance inside a pipe by using a stuck substance removing device equipped with a motor has been used. Patent 654986 proposes a dry matter removing apparatus using such a motor.

Since the equipment according to Patent No. 654986 uses a foreign material removing means such as a chain connected radially to the rotating body, the area contacted by the chain is considerably narrow, and it takes a considerable time to remove the fixed matter, and part of the fixing material There was a problem that parts that can not be removed.

In addition, since it is made of dry, dust may enter the inside of the machine and cause a breakdown, and only the wheel on one side may move elastically according to the height of the inner wall of the tube. Due to the vibration caused by the imbalance there was a problem that the fixing may not be properly removed.

In addition, there is a problem that it is difficult to remove the fixed material that does not easily fall by the attraction even after the impact on the inner wall of the tube with the device.

The present invention is to solve the above problems, the object of the present invention is to provide a device that can be carried out by an efficient operation by widening the area for removing the fixed matter.

Alternatively, since the high pressure water pipe 507 is connected to the high pressure water connecting pipe 506 of the water spray unit on one side, the high pressure water pipe 507 may be pulled forward by using the electric hose reel 10. As the fixed substance removing device 1 is moved forward, a constant scratch is formed on the inner wall of the tube, and high pressure water is sprayed through the water spray nozzle 504 to remove the fixed substance on the wall surface. The high pressure water also allows the fixation and the high pressure water to flow downstream to facilitate cleaning of the pipe after work. The wheels 405 are mounted to facilitate the fixation removal device 1 to move forward so that the device 1 can be easily moved. 8 is a state diagram of use of the deposit removing device 1 which is an embodiment of the present invention.
