specific Embodiment approach

[0050] The air motor 11 is installed on the discharge end of the feed pipe, and the feed pipe is connected with the communication pipe 111, and then the rotary cup 12 is installed at the other end of the air motor 11, and the communication pipe 111 is connected with the inside of the rotary cup 12;

[0051] Pass compressed air into the air motor 11 from the intake pipe 113 to drive the rotating part 112 of the air motor to rotate and drive the rotary cup 12 to rotate, and then feed the rotary cup 12, so that the paint is passed into the rotary cup 12 from the communication pipe 111;

[0052] Extend the spraying device into the pipeline, and the gas in the air motor 11 is sprayed out from the gas outlet 114;

[0053] After the paint enters the high-speed rotating cup 12, it is atomized at a position below 1 / 3 of the height of the cup 12. Shaped hole section 122 is sprayed outwards, and the remaining small amount of paint is sprayed outwards from annular hole section 123, so tha...

Abstract

The invention relates to a spraying device for pipeline repair and its use method, comprising: an air motor fixedly installed at the discharge end of a feed pipe, the air motor is provided with a sprayer for the paint to pass through and communicated with the feed pipe The connecting pipe; and the rotary cup connected to the end of the air motor away from the feed pipe and connected to the connecting pipe. The cup rotates, so that the paint in the cup is atomized by high-speed rotation and sprayed out from the spray hole group. The invention effectively solves the problem of dangerous use of the electric motor, and uses the air motor to drive the rotary cup to rotate, which ensures construction safety and can realize a single long-distance spraying. In addition, the structure of the rotary cup is optimized so that the paint is evenly sprayed on the inner wall of the pipeline .

Description

technical field [0001] The invention relates to the field of building construction, in particular to a spraying device for repairing pipelines and an application method thereof. Background technique [0002] At present, long-term running water supply pipelines are affected by factors such as the underground environment, raw water quality, and pipeline materials, which will inevitably lead to defects such as pipeline corrosion, damage, scaling, and oxidation. A coating is formed inside to repair the above defects. However, most of the existing spraying equipment uses a rotary cup to drive and connect with an electric motor. Spraying to the pipe wall, however, when this method is actually used, the electric motor will be damaged due to high temperature for a long time due to long-term high-speed operation, and even in high-temperature weather, the paint will be atomized and form dust when encountering a high-temperature motor. There is also the danger of leakage and short cir...
