Description

A metal pipe corrosion protection device Technical Field

[0001] This utility model relates to the field of pipeline corrosion protection technology, and in particular to a metal pipeline corrosion protection device. Background Technology

[0002] Steel pipes are a common fluid transport method used in water conservancy fields such as irrigation and water supply and drainage. Their widespread application is due to their low cost, simple production, strength, and ease of repair. However, the lifespan of steel pipes is limited by the metal itself. Steel pipes in contact with water will oxidize and corrode. This corrosion gradually reduces the wall thickness, eventually leading to rust penetration and leaks, ultimately causing the metal pipe to fail. Therefore, coating the pipes with various anti-corrosion materials to isolate them from water and air, thus preventing or slowing down corrosion, is an excellent way to extend their lifespan.

[0003] Currently, the most widely used anti-corrosion methods include spraying, polyurethane spraying, four layers of oil and one layer of cloth, and epoxy / PE powder hot-melt coating. Mechanical equipment is limited by its length and is mostly of a fixed length or range. For metal pipes of varying lengths, manual coating is often used for anti-corrosion. However, manual anti-corrosion has its own drawbacks: the diameter cannot be too small to avoid restricting the working radius; the anti-corrosion thickness is uneven or there may be omissions; dust from the bottom of the foot contaminates the inner wall; poor ventilation can affect the health of the anti-corrosion material; and, in particular, heated epoxy / PE powder hot-melt anti-corrosion (>200℃) can easily lead to heatstroke or burns. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a metal pipeline anti-corrosion device that can be used for internal anti-corrosion of pipelines of different lengths and diameters, ensuring uniformity and consistency of anti-corrosion, and improving the anti-corrosion effect and production efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An embodiment of this utility model provides a metal pipeline corrosion protection device, comprising:

[0007] Roller frame assembly for supporting metal pipes;

[0008] The spraying system includes a propulsion device and a feeding device. The feeding device includes a storage tank, which is connected to multiple nozzles via a feeding pipe. The nozzles are used to spray the inner wall of a metal pipe. The propulsion device includes a pipe body, with multiple feeding pipe supports distributed along the length of the pipe body. The feeding pipe supports are used to support the feeding pipe.

[0010] As a further implementation, the pipe body is equipped with multiple fixing clips for fixing the nozzle.

[0011] As a further implementation, the tube body is connected to a tail handle.

[0012] As a further implementation, a side handle is connected to the side of the tube body.

[0016] As a further implementation, the mounting bracket includes a fixing hook, which is connected to the base via a vertical rod.

[0017] As a further implementation, the fixing hook can be a single hook head, a double hook head, or a clamp structure.

[0018] As a further implementation, the roller frame assembly includes an active roller frame and a driven roller frame, and the gap between the active roller frame and the driven roller frame is adjusted by a lead screw transmission mechanism.

[0037] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0038] Example 1:

[0039] This embodiment provides a metal pipe corrosion protection device, as shown in Figures 1-8. The pipe and fittings are placed horizontally and rotated. Then, a powder spraying system with pulley brackets and a long handle is used. By controlling the forward and backward movement of the spraying system, the inner wall of the pipe and fittings is protected against corrosion. The whole device consists of roller frame group 1, rolling frame 2, fixed frame 3, and spraying system.

[0040] As shown in Figures 1-3, the roller frame assembly 1 is used to place metal pipes and enable the metal pipes to move. The roller frame assembly 1 includes an active roller frame with a motor and a driven roller frame without a motor 102, which is an existing structure. The idler roller 101 in the active roller frame is connected to the motor 102 and is installed on the upper side of the idler roller base 103. The lower side of the idler roller base 103 is connected to the support base 106 through the hydraulic support 105. The idler roller base 103 is connected to the screw drive mechanism. By rotating the screw 104, the idler roller base 103 is moved closer to or away from the driven roller frame, thereby adjusting the gap between the two idler rollers 101 to accommodate steel pipes of different diameters.

[0041] The rolling frame 2 supports the sprinkler system and enables its movement. As shown in Figures 4(a) and 4(b), the rolling frame 2 includes a rotating wheel 201, a rotating wheel fixing plate 202, a bearing rod 203, a first upright 204, and a first base 205. The bottom of the first upright 204 is connected to the first base 205, and the top is connected to the mounting seat 202. The mounting seat 202 mounts the rotating wheel 201 via the bearing rod 203. The bottom of the sprinkler system is supported by multiple rolling frames 2, and the multiple rotating wheels 201 enable the sprinkler system to move.

[0042] The fixing frame 3 is used to fix the sprinkler system when it is not in use. The fixing frame 3 includes fixing hooks 301, a second upright 302, and a second base 303. The bottom of the second upright 302 is connected to the second base 303, and several fixing hooks 301 are installed on the top. The fixing hooks 301 hook the sprinkler system to achieve support and fixation. The fixing hooks 301 adopt a single hook head as shown in Figure 5(a), a double hook head as shown in Figure 5(b), or a clamp structure as shown in Figure 5(c).

[0043] As shown in Figures 6-8, the spraying system includes a propulsion device 4 and a feeding device 5. The feeding device 5 includes a feeding pipe 502, a nozzle 501, and a storage tank 503. The feeding pipe 502 has a certain length, with multiple branches installed at one end. Each branch is equipped with one or more nozzles 501, and the other end is connected to several storage tanks 503. The storage tanks 503 store anti-corrosion powder, and the storage tanks 503 are connected to high-pressure air. Under the action of high-pressure air, the anti-corrosion powder is sprayed out through the nozzles 501.

[0044] The propulsion device 4 includes a horizontally arranged tube 401, which is a long tube of a certain length. The tube 401 is supported by multiple rolling frames 2. When not in use, the tube 401 is hooked to a fixing hook 301. Multiple feed tube supports 402 are spaced apart on the upper side of the tube 401, which support the feed tube 502. In this embodiment, the feed tube supports 402 have a U-shaped support portion. Multiple fixing clips 405 are provided on the side of the tube 401 to fix the nozzle 501 and prevent the nozzle 501 from moving during the spraying process.

[0045] The front end of the pipe body 401 faces the metal pipe, and the rear end of the pipe body 401 is equipped with a tail handle 403. By pushing the tail handle 403, the pipe body 401 can be moved along the rolling frame 2. In order to facilitate pushing the pipe body 401, a side handle 404 is also installed on the side of the pipe body 401. The side handle 404 is symmetrically installed with respect to the pipe body 401.

[0046] The working principle of this embodiment is as follows:

[0047] When performing anti-corrosion treatment on pipes (fittings), the metal pipe is hoisted up and placed horizontally on the roller 101 of the roller frame group 1. The power is turned on to make it rotate. The fixing frame 3 supporting the pipe body 401 is removed, the tail handle 403 is grasped and straightened, and the pipe body 401 is placed on the rolling frame 2. The pipe body 401 moves smoothly back and forth by the rolling of the rotating wheel 201 when it is pushed back and forth.

[0048] The pushing device 4 is pushed into the metal pipe. After reaching the deepest part of the pipe, the power switch of the feeding device 5 is turned on. The high-pressure air connected to the storage tank 503 drives the anti-corrosion powder inside to be transported forward through the feeding pipe 502. After being sprayed out through the nozzle 501, it is sprayed onto the inner wall of the pipe (component) to complete the anti-corrosion operation.

[0049] Depending on the required thickness, after spraying for a certain time and thickness, the pushing device 4 will be pulled out of the pipe a certain distance, and the appropriate thickness will be sprayed again before pulling it out. This process is repeated until the corrosion protection of the entire inner wall is completed. Then, the entire spraying system will be pulled out of the pipe and pulled out a certain distance before the fixing bracket 3 is used to fix the spraying system.

[0050] This embodiment achieves internal corrosion protection of pipes and fittings by placing and rotating metal pipes horizontally and then using a spray system with pulley supports and handles. The forward and backward movement of the spray system is controlled. This embodiment is applicable to internal corrosion protection of pipes of different lengths and diameters (>600mm), improving production efficiency and corrosion protection effect, ensuring uniform corrosion protection, and reducing labor intensity and safety risks.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
