Description

[0001] The present invention relates to a blasting apparatus for cleaning a duct,

More particularly, the present invention relates to a blast bogie that performs both channel cleaning and roughing formation, and more particularly, to a blasting bogie that performs both cleaning of a duct and formation of roughness, And clean the foreign material on the inner wall surface of the pipe through the high pressure water and simultaneously form the roughness on the inner wall surface of the pipe through the high pressure metal powder so that it is convenient and quick in one operation process The present invention relates to a blast bogie for cleaning a duct wall and for performing a roughing forming operation.

Generally, water pipes, dirt, gas and the like are supplied to the inner wall of the pipe when the pipe is aged and used for a long period after installation, such as water pipe of middle or large diameter for supplying tap water, small diameter water pipe, sewage pipe for discharging sewage, Various kinds of foreign substances contained in the fluid of the fluid are sludged and when the conduit is made of a metallic material, the inner surface of the conduit is oxidized to generate rust, and these are solidified to form a scale layer.

Since the sludge or scale layer formed by the deposition of rust and foreign matter formed on the inner surface of the fluid channel is gradually thickened and solidified with the lapse of time, it obstructs the smooth flow of the fluid, And the scale layer attached to the pipeline melts into the fluid, causing the fluid to be contaminated.

Particularly, there has been reported a case where the operation of the reactor due to the inflow of foreign matter is stopped in the nuclear water seawater piping.

Therefore, in order to solve such a problem, it is necessary to clean the pipe line, draw scrapers accumulated in the pipe line by pulling separate equipment into the pipe line, and use a scrapers method and a water jetting method using high- (Water jet) method, and a poly-pig construction method in which the scale layer on the inner surface of the pipe is removed by rushing the poly pigs by high pressure have been developed and applied in the field.

A device using high-pressure water is usually introduced into the pipe to remove the sludge or scale layer on the pipe wall. However, there is a problem that it is difficult to completely remove the sludge and scale layer from the high-pressure waterway.

In addition, when the channel cleaning is performed, a painting operation is performed in which a coating material is applied and painted inside the wall surface of the duct. Normally, when the inner wall surface is cleaned by water pressure, the roughness of the wall surface is somewhat lowered, There is a problem that the coating material is easily peeled from the wall surface due to a low adhesion force of the coating material to be applied.

Therefore, when painting is required on the surface of the channel, an operation for forming a roughness on the wall surface of the channel should be performed after the channel cleaning with the high-pressure water is completed.

Therefore, there is a problem in that it takes too much time together with inconvenience in forming a channel cleaning and illuminance because two operation steps are required due to the input of each device in order to clean the inside of the channel and form the roughness.
