Description

Technical Field

[0001] This utility model relates to the field of pipeline corrosion protection, and in particular to a device for spraying anti-corrosion powder onto the inner wall of a pipeline. Background Technology

[0002] In the field of pipeline corrosion protection, spraying anti-corrosion powder onto the inner wall of the pipeline is an important means to extend the service life of the pipeline. In the existing technology, when spraying anti-corrosion powder onto the inner wall of the pipeline, the cleaning treatment of the inner wall surface of the pipeline is often neglected, which causes impurities and rust on the inner wall of the pipeline to affect the adhesion effect of the anti-corrosion powder and reduce the anti-corrosion performance.

[0003] Meanwhile, traditional pipe inner wall spraying devices usually cannot effectively combine cleaning and spraying functions. They either require a separate cleaning device to clean the inner wall of the pipe first, or although they have a certain cleaning function, it is difficult to switch between cleaning and spraying processes through simple operation.

[0004] The device provided in this solution for spraying anti-corrosion powder on the inner wall of pipelines can first introduce high-pressure gas to clean the inner wall of the pipeline using cleaning components before spraying. Then, this device is re-installed and anti-corrosion material is introduced to treat the inner wall of the pipeline for anti-corrosion treatment, effectively solving the above-mentioned technical problems.

[0039] In the preferred embodiment, a sliding sleeve 206 is provided between the second connecting rod 202 and the main rod 1, and a push rod 204 is provided between the sliding sleeve 206 and the second connecting rod 202.

[0040] In the preferred embodiment, one end of the main rod 1 is also provided with a tailstock 101, and a spring 105 is provided between the sliding sleeve 206 and the tailstock 101. The spring 105 is used to push the sliding sleeve 206 to make the telescopic frame 2 unfold outward.

[0041] In the preferred embodiment, the rotating sleeve 301 is rotatably sleeved on the outside of the rotating seat 305, and a bearing is provided between the rotating sleeve 301 and the rotating seat 305.

[0042] The outer circumferential surface of the rotating sleeve 301 is also provided with multiple cleaning brackets 302, and the cleaning components 4 are arranged on the cleaning brackets 302.

[0043] In the preferred embodiment, the cleaning bracket 302 is also provided with a first elongated hole 303;

[0044] The cleaning assembly 4 includes a telescopic plate 401, on which a second elongated hole 402 is provided. The second elongated hole 402 corresponds to the position of the first elongated hole 303. A locking bolt 304 is provided in the first elongated hole 303. The locking bolt 304 passes through the first elongated hole 303 and the second elongated hole 402. The locking bolt 304 is used to lock the cleaning assembly 4 and the cleaning bracket 302.

[0045] In the preferred embodiment, the top of the telescopic plate 401 is provided with a cleaning plate groove 403, the cleaning plate groove 403 is provided with a detachable brush 405, and the end face of the cleaning plate groove 403 is provided with a detachable limiting base plate 404, which is used to limit the brush 405.

[0046] In a preferred embodiment, the spraying assembly 5 includes multiple spraying supports 501 evenly distributed on the outer circular surface of the rotating sleeve 301. The spraying supports 501 are provided with spraying pipes 502, and the top end of the spraying pipes 502 is provided with inclined pipes 503.

[0047] The device for spraying anti-corrosion powder onto the inner wall of a pipe is used as follows: First, the entire device is placed into the port of the pipe to be treated. The spring 105 between the tailstock 101 and the sliding sleeve 206 will push the sliding sleeve 206 with its own elastic potential energy. After being subjected to force, the sliding sleeve 206 drives the second connecting rod 202 of the telescopic frame 2 to move through the push rod 204. In conjunction with the first connecting rod 201, the horizontal connecting rod 203 extends outward. The rollers 205 at both ends of the horizontal connecting rod 203 then fit tightly against the inner wall of the pipe, forming a stable three-point or multi-point support to ensure the stability of the device inside the pipe.

[0048] In the first stage, the inner wall of the pipe is cleaned. The telescopic plate 401 is adjusted to a suitable length, and then high-pressure compressed air is introduced into the inner cavity 106 of the main rod 1 through the injection pipe 102. The compressed air is transmitted along the inner cavity 106 to the rotating head 3 at the top of the main rod 1. Since the rotating sleeve 301 is rotatably sleeved on the outside of the rotating seat 305 through the bearing, the impact force of the high-pressure air will drive the rotating sleeve 301 to rotate at high speed. The cleaning bracket 302 on the outer circumference of the rotating sleeve 301 will rotate synchronously. The telescopic plate 401 of the cleaning assembly 4 has been firmly fixed to the cleaning bracket 302 through the locking bolt 304 passing through the first long hole 303 and the second long hole 402.

[0049] The brush 405 inside the cleaning plate groove 403 at the top of the telescopic plate 401 acts like a high-speed cleaning brush during high-speed rotation, cleaning the inner wall of the pipe in all directions, removing dust, rust, oil and other impurities attached to the inner wall one by one. The debris generated during cleaning is discharged outside the pipe along the pipe under the strong thrust of high-pressure air, thus completing the cleaning work of the inner wall of the pipe.

[0050] After the cleaning process is completed, the device is removed from the pipeline, re-laid out, and then accurately placed back into the designated position on the pipeline, ensuring that the roller 205 is once again in contact with the inner wall of the pipeline. Then the filling device is started, and the anti-corrosion powder enters the inner cavity 106 of the main rod 1 through the injection pipe 102, and is conveyed along the inner cavity 106 to the spraying assembly 5 of the rotating head 3.

[0051] The spray pipes 502, which are evenly distributed on the spray support 501 on the outer circular surface of the rotating sleeve 301, spray the anti-corrosion powder in a spiral shape at high speed through the inclined pipe 503 under the continuous rotation of the rotating sleeve 301. The special angle design of the inclined pipe 503, together with the rotation of the rotating sleeve 301, allows the anti-corrosion powder to be evenly covered in every corner of the inner wall of the pipe under the combined action of centrifugal force and airflow, forming a dense and uniform anti-corrosion protective layer, and efficiently completing the anti-corrosion spraying work on the inner wall of the pipe.

[0052] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
