Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a coating film removing apparatus for regenerating superannuated pipes,

More particularly, the present invention relates to a coating film crushing apparatus and method for a paint film crushing apparatus and method for a water and sewage sludge pipe, and more particularly to a paint film crushing apparatus, When the blade collides with the wall surface of the duct in the process of crushing, the buffer frame coupled to both ends of the blade rotating shaft is lifted and lowered by the elastic force of the spring while the blade can crush only the coated film, The present invention relates to a device for crushing a coating film on a water pipe and a method for crushing the same.

The pipes used for conveying fluids such as general water pipes, sewer pipes, oil pipelines, and gas pipes are mainly made of cast iron pipes, steel pipes, synthetic pipes, and concrete pipes.

Among them, a large pipe mainly uses a cast iron pipe or a steel pipe. When a cast iron pipe or a steel pipe is used for a long time, it is corroded or damaged by aging due to fluid passing through the inside or other foreign matter.

In particular, in the case of a water pipe composed of a cast iron pipe or a steel pipe, the inside of the water pipe is prevented from being oxidized for safer drinking water supply. However, when the pipe is used for a long time, the coating portion inside the pipe is corroded or peeled.

As a way to solve this problem, there is a method to replace the whole pipeline, but the excavation work for replacing the entire pipeline causes traffic congestion, and it takes a lot of time and cost to replace the pipeline, As a result, the economic loss and the life span are shortened. Therefore, the non-excavation rehabilitation methods that are improved while the pipeline is left are being applied.

Prior arts related to the rehabilitation of such a retirement hall include patent registration No. 10-1084062, a method for rehabilitation of the retirement hall and rehabilitation equipment used for the rehabilitation.

In the above-mentioned line-registration invention, a paint film removing device is put into the inside of a waste pipe, and a rolling cutter (peeling and peeling) is rotated and brought into contact with the inner surface of the pipe to cut and remove the paint film. However, The coating film strongly adhered to the surface of the coating film does not fall off from the inner surface properly but remains partially adhered to the surface of the coating film to thereby reduce the removal effect of the coating film. In addition, when a new coating film is formed, the adhesion strength of the coating film is weak, The paint film may peel off from the inner surface.

In addition, since the conventional patents work by connecting paint film removing equipment, transfer bogie, shot blasting equipment and painting equipment in a line, if the operation of cutting the paint film of the paint film removing equipment is incomplete, the entire process must be repeated It is difficult to move and handle due to the large size of the whole equipment and the size of the paint film removing equipment varies according to the size of the small pipe and the large pipe. In particular, it takes a long time to assemble and separate the equipment of the entire process, which causes a problem such that the construction cost is excessively increased.
