When the washing step is completed, the coating step of coating the inner wall surface using an epoxy resin on the inner surface of the pipe (2) of the water and sewage pipe.

As described above, the pipe washing apparatus using the present invention and the method thereof will be described with reference to the accompanying drawings.

First, the present invention is configured to facilitate the movement of the washing device (1) mounted on the bottom surface 91 of the vehicle (90) and at the same time easy to handle and use.

The control box 4 formed at one side of the bottom surface 91 of the vehicle 90 operates each switch to operate the washing device 1, and when the power transmission device 80 is driven, the power transmission device 80 is operated. While operating the driving motor of the vacuum pump 60 to operate the high-pressure intake air sucks foreign matter such as rust, scale, etc. on the inner surface of the pipe (2). As a result, foreign matter falls from the inner surface of the pipe 2 and moves to the inside of the cyclone 31 of the first dust collecting member 30 along the suction hose 21. The foreign matter having a high specific gravity along the bottom surface of the cyclone 31 formed in a conical shape is collected in the dust collecting container 33, and the foreign matter having a low specific gravity is formed at the suction force and the central portion of the transfer pipe P of the first transport channel 37. Move upward along the internal flow to be passed through the transfer pipe (P) to move to the second dust collecting member 40 is discharged.

On the other hand, foreign matter moving along the conveying pipe (P) is passed through the cyclone 41 of the second dust collecting member 40, the foreign matter having a high specific gravity is collected in the dust collecting container 43, the foreign matter having a low specific gravity along the internal flow The third dust collecting member 50 is moved to the third dust collecting member 50 through the second conveying flow passage 45, wherein the third dust collecting member 50 is a centrifugal force flow that vertically acts on the first and second dust collecting members 30 and 40. Is to form a dust collector (51) in the horizontal length direction so that the flow caused by the centrifugal force acting horizontally to allow the foreign matter to be separated rapidly gradually.

The vacuum pump 60 formed at one side of the third dust collecting member 50 generates high-speed intake air by the driving force of the power transmission device 80 so that foreign substances such as rust and scale formed on the inner surface of the pipe 2 for a long time fall. By separating and filtering step by step in each of the transfer pipe (P) and the dust collecting container (33) (43) (51) to finally treat the fine foreign matter, the suction air of the vacuum pump 60 is pipe (2) By suctioning and treating foreign substances formed inside the branch 5 (the pipe entering the home) connected to the outer circumference of the wire), the branch 5 pipe is clogged due to the injection air of the A / S method. After breaking the connection to each branch (5) with a hose, it is possible to prevent the problem of having to recover dust and rust in advance.

As such, the air and fine foreign matter introduced into the vacuum pump 60 are moved to the silencer 61 again. At this time, the silencer 61 sucks the high-pressure intake air, and the air and the foreign matter are transferred to the transfer pipe P. Therefore, there is a feature that can suppress the generation of noise while moving as possible.

In the case of the conventional high-speed injection A / S method, the air moving along the transfer pipe (P) collides with the transfer pipe (P) severely generated, so that the transfer pipe (P) is easily broken, or as described above. It is a security that the construction period is long due to the report of the residents due to severe noise caused by the collision.

Finally, the fine foreign matter collected by the fourth dust collecting member 70 is fixed to the bracket 71a of the dust collecting container 71 by the operation of the angle adjusting device 74 so that the rod 75 is raised. Foreign matter collected in the dust collector (71) is to be easily discharged to the outside through the discharge port (72).

In addition, the angle adjusting device 74 may be used by installing the dust collector 71 in a state spaced apart from the bottom surface 91 so as to easily raise and lower the dust collector 71 to the upper and lower portions.

Through such a series of processes, foreign substances such as rust and scale on the inner surface of the pipe (2) are collected and separated step by step, so that even minute foreign substances collected in the final stage can be easily discharged to the outside, and at the same time, through the dust collecting member separated in stages. The foreign matter is sequentially collected in each of the dust collecting cylinders 33, 43, 51, 71 to prevent the phenomenon that the transfer pipe (P) is blocked in advance.

On the other hand, after the dust collection and separation work of the foreign matter is carried out cleaning work to inject the silica, the pipe (2) guide hole (3) by supplying the silica from the other side and finally attached to the inner surface of the pipe (2) and conveyed Cleaning the foreign matter attached to the pipe (P) so that it can be discharged to the outside through the discharge holes 36, 440 (52, 72) of the dust collecting container (33) (43) (51) (71).

On the other hand, the silica that is sucked into the intake air is able to remove the foreign matter while colliding with the fine foreign matter remaining on the inner wall of the pipe (2) while generating a spark while colliding with the inner surface of the pipe (2) due to the flow of the intake air. Here, silica injection is an option that may or may not be performed prior to the water washing operation.

In addition, in the coating operation, when the epoxy resin is sucked by using the intake air by adding an epoxy resin in addition to the case of the silica sand, the epoxy resin is in close contact with the inner surface of the pipe (2) and can also be quickly coated with epoxy. have.

7 is a view showing another embodiment of the present invention by connecting the suction hose 21 of the fixing member 10 and the connecting member 20 to the guide hole 3 of the pipe 2 and then the suction hose 21 The end of the dust collector is connected to the transfer pipe (P) formed in the dust collector 110 of the first dust collecting member 100, the foreign matter is collected inside the dust collector 110, wherein the dust collector 110 is a predetermined length in the vertical direction Formed to have and to form a large dust collector (110) to accommodate a large amount of foreign matter therein.

As the vacuum pump 300 operates by driving the power transmission device 400, high-pressure suction air sucks foreign substances into the inner surface of the pipe 2, and foreign substances introduced into the suction hose 21 are suction hoses 21. And the water is supplied to the inside of the suction hose 21 so as not to accumulate in the dust collecting container 110 so that foreign substances are introduced into the dust collecting container 110 together with the water.

The water and foreign substances introduced in this way are accumulated inside the dust collecting container 110, and the foreign matter having a small specific gravity is collected in the second dust collecting member 200 along the conveyance flow path 180.

Here, the second dust collecting member 200 has the same structure as the first and second dust collecting members 30 and 40 described in the beginning and has the same function.

On the other hand, when the water and foreign matter introduced to the first dust collecting member 100 is accumulated to some extent through the viewing window 190 formed on the outside to check the inside and then operate the angle adjusting device 140 to the rod 150 vertically When the dust collector 110 is inclined at a predetermined angle with respect to the pedestal 170, the outlet 120 is opened to discharge water and foreign matters to the outside.

Such a washing device (1) is to be used in the alleys or narrow streets that large vehicles can not enter by reducing the overall volume or when the washing of small water supply pipe is required.
