Description

Technical Field

[0001] The present invention relates to the field of pipeline anti-corrosion, and in particular to a surface anti-corrosion treatment device and a treatment method for a flexible hydrogen transmission pipeline. Background Art

[0002] A hydrogen pipeline is a pipeline system used to transport hydrogen. With the development and application of hydrogen energy, the construction and operation of hydrogen pipelines have become increasingly important. These pipelines need to have high strength and corrosion resistance to ensure the safe transportation of hydrogen. In addition, the design and construction of hydrogen pipelines also need to consider factors such as hydrogen pressure, temperature and flow to ensure the stability and reliability of the pipeline system. With the popularization of hydrogen energy, hydrogen pipelines will play an important role in promoting the sustainable development of clean energy.

[0003] The corrosion protection of hydrogen pipelines is very important because hydrogen has high permeability and embrittlement effect, which can easily cause corrosion and leakage of pipelines. Accordingly, the outer wall of the hydrogen pipeline needs to be anti-corrosion. In the existing technology, the outer wall of the hydrogen pipeline is usually sprayed with an anti-corrosion coating. The anti-corrosion coating, such as epoxy resin coating, polyethylene coating, etc., is applied to the outer surface of the pipeline to provide an additional protective layer for the outer wall of the pipeline to prevent corrosive media from directly contacting the pipeline.

[0004] When workers apply an anti-corrosion layer to the outer wall of a hydrogen transmission pipeline, they usually use a suction pump to suck the anti-corrosion coating inside the anti-corrosion box onto the spraying part, and then make the spraying part face the outer wall of the hydrogen transmission pipeline to spray the outer wall with anti-corrosion. Since the spraying work is carried out for a long time, the epoxy resin coating inside the anti-corrosion box is affected by the external temperature for a long time, which causes it to decrease, and accordingly the resin coating solidifies. In the prior art, only a mixing part is provided inside the anti-corrosion box to mix and stir the resin raw materials inside the anti-corrosion box. This method only slows down the time for the resin raw materials to solidify, and cannot dilute the solidified resin coating, which correspondingly reduces the use efficiency of the resin coating.

[0005] The solidified resin coating is prone to adhesion and blockage at the suction port of the suction pump at the bottom, which correspondingly reduces the efficiency of the suction pump in sucking out and spraying the resin coating inside the anti-corrosion box. At this time, the staff needs to manually add a catalyst to the inside of the anti-corrosion box to dilute the resin coating. This method reduces the staff's efficiency in anti-corrosion treatment of the outer wall surface of the hydrogen pipeline. For this reason, a surface anti-corrosion treatment device and a treatment method for a flexible hydrogen pipeline are proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a surface anti-corrosion treatment device and treatment method for a flexible hydrogen pipeline, so as to solve the problem that when the resin coating solidifies, the staff's efficiency in adding catalyst is slow, thereby reducing the staff's work efficiency in anti-corrosion treatment of the outer wall surface of the hydrogen pipeline.

[0019] A method for treating a surface anti-corrosion treatment device of a flexible hydrogen transmission pipeline, comprising:

[0020] S1: When the staff performs anti-corrosion treatment on the outer wall of the hydrogen transmission pipeline, they first place the hydrogen transmission pipeline to be treated with anti-corrosion under the fixed plate, and then turn on the servo motor and the suction pump to make them work;

[0021] S2: When the suction pump is working, the resin coating inside the anti-corrosion box enters the interior of the suction pump through the first discharge pipe and the feed hose, then enters the interior of the protection box through the feed channel, and then enters the interior of the arc spray plate through the second discharge pipe, and finally is sprayed out through the spray hole at the bottom of the arc spray plate;

[0022] S3: When the resin coating inside the anti-corrosion box is sucked out and sprayed through the filter mesh plate, the suction force above the filter mesh plate increases accordingly according to the suction force of the suction pump. As the stirring plate rotates, the rotating plate drives the dredging brush to rotate to the top of the filter mesh plate to clean the top of the filter mesh plate;

[0023] S4: Due to the low suction efficiency of the cured resin coating by the suction pump, when the rotating plate drives the dredging brush to rotate to the top of the filter mesh plate, the sliding plate drives the sliding rod and the limit plate to slide downward. At this time, the support rod drives the sliding block to slide in the position where it cannot block the outlet. At this time, the catalyst inside the storage chamber can flow back and forth to the outside of the rotating plate through the outlet and the outlet channel.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention proposes an anti-corrosion treatment method for a surface anti-corrosion treatment device for a flexible hydrogen transmission pipeline, which provides a dredging agent discharging mechanism on the outer wall of a stirring plate to:

[0026] When the resin coating inside the anti-corrosion box does not cure:

[0027] According to the suction effect of the suction pump, the dredging brush can be attracted downward, so that the sliding plate drives the dredging brush to extend to the position of the filter mesh plate, so that the dredging brush extends to the filter holes on the filter mesh plate, and the filter holes on the filter mesh plate can be dredged, thereby reducing the adhesion of resin paint to the inside of the filter holes, improving the permeability of the filter holes, and increasing the efficiency of the filter mesh plate in sucking out and spraying the resin paint. At the same time, the rotation of the dredging brush can be used to rotate the bottom end of the dredging brush to remove the resin paint attached to the filter mesh plate, thereby correspondingly improving the use effect of the filter mesh plate in sucking out and spraying the resin paint.

[0028] When the resin coating inside the anti-corrosion box solidifies:

[0029] Since the resin coating with the solidification phenomenon is sucked out by the suction pump in a low efficiency, the sliding position of the sliding stopper cannot block the discharge port, and the catalyst inside the storage chamber can flow back and forth to the outside of the rotating plate through the discharge port and the discharge channel. The rotation of the stirring plate can fully mix the catalyst with the resin coating inside the anti-corrosion box to dilute the resin coating with the solidification phenomenon inside the anti-corrosion box. Through the setting of this structure, as the solidification phenomenon of the resin coating intensifies, the suction efficiency of the suction pump for the resin coating inside the anti-corrosion box is reduced, and the sliding stopper can be used to block the discharge port to automatically add the catalyst, so that the staff does not need to manually add the catalyst for diluting the resin coating to the inside of the anti-corrosion box, thereby improving the work efficiency of the staff in anti-corrosion treatment of the outer wall surface of the hydrogen transmission pipeline.

[0030] The present invention proposes an anti-corrosion treatment method for a surface anti-corrosion treatment device of a flexible hydrogen pipeline. By arranging a storage spray mechanism at the bottom of the anti-corrosion box, after the spraying anti-corrosion work is completed, the arc spray plate can be stably located inside the protection box to avoid the spray holes at the bottom thereof from contacting with dust in the outside air, thereby correspondingly improving the spraying effect of the arc spray plate when working. During the spraying operation, according to the sliding extrusion effect of the resin coating on the sliding pressure plate, the arc spray plate can automatically extend to the outside of the protection box, thereby correspondingly reducing the operating steps for the staff to remove the arc spray plate, thereby improving the work efficiency of the staff in spraying anti-corrosion on the outer wall of the hydrogen pipeline.

[0042] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 As shown, a surface anti-corrosion treatment device for a flexible hydrogen pipeline includes an anti-corrosion box 1, and also includes: a mobile mixing mechanism for mobile spraying of the outer wall of the hydrogen pipeline and rotationally mixing the resin coating inside the anti-corrosion box 1, the mobile spraying mechanism is located below the anti-corrosion box 1, the mobile mixing mechanism includes fixed plates 2 installed on both sides of the bottom of the anti-corrosion box 1, one side of the outer wall of the fixed plate 2 is fixedly connected to a servo motor 201, a fixed frame 202 is fixedly connected between the two fixed plates 2, the internal rotation of the fixed frame 202 is connected to a reciprocating screw 201, the internal rotation of the anti-corrosion box 1 is connected to a rotating shaft 205 and one end of the rotating shaft 205 rotates and extends to the outside of the anti-corrosion box 1, the outer wall of the rotating shaft 205 is located inside the anti-corrosion box 1 and is fixedly connected to a stirring plate 206, and the reciprocating screw 203 and the outer wall of the rotating shaft 205 are both fixedly connected to a rotating gear 204;

[0043] The present invention is further specifically described in detail. A rotation groove is formed on both the fixed frame 202 and the fixed plate 2, and one end of the reciprocating screw 203 is rotated and extended to the output end of the servo motor 201 through the rotation groove and is fixedly connected thereto. The end of the reciprocating screw 203 away from the servo motor 203 is rotated and extended to the outside of the fixed plate 2 through the rotation groove. The two rotating gears 204 are both located outside the fixed plate 2. The two rotating gears 204 are fully meshed, and the reciprocating screw 203 is transmission-connected to the rotating shaft 205 through the rotating gears 204.

[0044] Through the setting of the above technical solution, in specific use: when the staff performs anti-corrosion treatment on the outer wall of the hydrogen pipeline, first prevent the hydrogen pipeline to be treated for anti-corrosion from being placed under the fixed plate 2, and then turn on the servo motor 201 and the suction pump 302, so that the servo motor 201 and the suction pump 302 are working. When the servo motor 301 is working, it drives the reciprocating screw 203 to rotate, and accordingly, according to the function of the threaded connection between the protection box 3 and the reciprocating screw 203, the protection box 3 drives the arc-shaped spray plate 3013 below it to reciprocate, which can be The outer wall of the hydrogen transmission pipeline is sprayed reciprocatingly, and the two rotating gears 204 are fully engaged, which can drive the rotating shaft 205 and the stirring plate 206 to rotate, and the resin coating inside the anti-corrosion box 1 can be fully stirred accordingly, which slows down the curing time of the resin coating, thereby improving the staff's use of the resin coating. Using a servo motor 201, the spraying work can be reciprocated, and at the same time, the curing time of the resin coating inside the anti-corrosion box 1 is slowed down, thereby improving the staff's use efficiency of this device;

[0045] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the arc-shaped spray plate 3013 and the storage spraying mechanism are used to automatically open and store the sprayed arc-shaped spray plate 3013, and the storage spraying mechanism is located on the mobile mixing mechanism. The storage spraying mechanism includes a protection box 3 threadedly connected to the outer wall of the reciprocating screw 203, and a suction pump 302 is fixedly installed on the top of the protection box 3. A first discharge pipe 301 is fixedly installed on the bottom of the outer wall of the anti-corrosion box 1, and a feed hose 303 is connected to the bottom of the first discharge pipe 301. The bottom of the inner wall of the protection box 3 is rotatably connected to a rotating rod 304, and one end of the rotating rod 304 rotates and extends to the outside of the protection box 3. The end of the rotating rod 304 is located outside the protection box 3 and is fixedly connected to a fixed disk 305. The inner side of the fixed disk 305 is fixedly connected to a torsion spring 306. The outer wall of the rotating rod 304 is located inside the protection box 3 and is fixedly connected to a protective baffle 307.

[0046] The present invention is further specifically described in detail. The end of the feed hose 303 away from the first discharge pipe 301 is connected to the suction pump 302, and the length toughness of the feed hose 303 is greater than the length of the fixed frame 202. The end of the torsion spring 306 away from the fixed plate 305 is connected to the outer wall of the protection box 3. The outer wall of the protective baffle 307 and the inner wall of the protection box 3 are slidingly fitted. The bottom of the protective baffle 307 is fixedly connected to a pull plate. A feed port is provided at the top of the first discharge pipe 301, and the feed port extends to the interior of the anti-corrosion box 1 and is communicated with the interior thereof. A filter mesh plate is provided inside the feed port. The suction pump 302 and the interior of the anti-corrosion box 1 are communicated with the first discharge pipe 301 through the feed hose 303.

[0047] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the storage spraying mechanism also includes a feeding channel 308 opened inside the protection box 3, and limiting sliding grooves are opened on both sides of the inner wall of the protection box 3. The interior of the limiting sliding groove is fixedly connected to a limiting square plate 309, and the outer wall of the limiting square plate 309 is slidably connected to a limiting slider 3010. A sliding pressure plate 3011 is fixedly connected between the two limiting sliders 3010, and the bottom of the sliding pressure plate 3011 is fixedly installed with the first and second discharge pipes 3012, and the arc-shaped spray plate 3013 is fixedly connected to the bottom end of the first and second discharge pipes 3012;

[0048] The present invention is further specifically described in detail. The feed channel 308 is correspondingly connected to the bottom of the suction pump 302. The outer wall of the limiting slider 3010 is slidingly fitted with the inner wall of the limiting slide groove. The outer wall of the sliding pressure plate 3011 is slidingly fitted with the inner wall of the protection box 3. A discharge port is provided on the top of the first and second discharge pipes 3012. The discharge port is smaller than the diameter of the feed channel 308. The interior of the arc spray plate 3013 is hollow and connected to the interior of the first and second discharge pipes 3012. A plurality of spray holes are provided at the bottom of the arc spray plate 3013. The bottom end of the arc spray plate 3013 is pressed against the inner side of the protective baffle 307. The gravity of the arc spray plate 3013 driven downward by the sliding pressure plate 3011 is smaller than the rotation force of the protective baffle 307 by the torsion spring 306.

[0049] Through the setting of the above technical solution, when it is used specifically: when the suction pump 302 is working, the resin coating inside the anti-corrosion box 1 enters the interior of the suction pump 302 through the first discharge pipe 301 and the feed hose 303, and then enters the interior of the protection box 3 through the feed channel 308, and then enters the interior of the arc spray plate 3013 through the first and second discharge pipes 3012, and finally is sprayed out through the spray hole at the bottom of the arc spray plate 3013. According to the effect that the feed channel 308 is larger than the diameter of the first and second discharge pipes 3012, the resin coating entering the protection box 3 can squeeze the sliding pressure plate 3011, so that the sliding pressure plate 3011 drives the first and second discharge pipes 3012 and the arc spray plate 3013 to press the protective baffle 3011 downward, so that the arc spray plate 3013 automatically extends to the outside of the protection box 3. After the anti-corrosion spraying work is completed, the arc spray plate 3013 is slid upward to be slid and stored in the interior of the protection box 3, and then Afterwards, the protective baffle 307 is rotated. Since the gravity of the arc spray plate 3013 driven downward by the sliding pressure plate 3011 is less than the rotation force of the torsion spring 306 on the protective baffle 307, the inner side of the protective baffle 307 can stably press the bottom of the arc spray plate 3013, so that the arc spray plate 3013 is stably located inside the protection box 3. Through the arrangement of this structure, after the spraying anti-corrosion work is completed, the arc spray plate 3013 can be stably located inside the protection box 3, avoiding the contact of the spray hole at its bottom with dust in the outside air, thereby correspondingly improving the spraying effect of the arc spray plate 3013 when working. During the spraying work, according to the sliding squeezing effect of the resin coating on the sliding pressure plate 3011, the arc spray plate 3013 can automatically extend to the outside of the protection box 3, thereby reducing the number of operating steps for the staff to remove the arc spray plate 3013, thereby improving the work efficiency of the staff in spraying anti-corrosion on the outer wall of the hydrogen transmission pipeline;

[0050] It should be noted that the square-shaped limit baffle 309 is used to prevent the sliding plate 3011 from sliding and tilting on both sides when the resin coating is squeezed, thereby improving the vertical spraying effect of the arc-shaped spray plate 3013.

[0051] It should be noted that the aperture of the filter mesh plate can only filter out the uncured resin coating, thereby preventing the cured resin coating from entering the first discharge pipe 301, thereby improving the effect of the first discharge pipe 301 in sucking out the resin coating.

[0052] like Figure 6 、 Figure 7 、 Figure 8 、 Figure 9As shown, the dredging and discharging mechanism is used to dilute the resin coating inside the anti-corrosion box 1. The dredging and discharging mechanism is located inside the anti-corrosion box 1. The dredging and discharging mechanism includes a rotating plate 4 fixedly connected to the outer wall of the stirring plate 206, and the interior of the sliding cavity 401 is provided with a sliding plate 402, and one end of the sliding plate 402 slides and extends to the outside of the rotating plate 4. The end of the sliding plate 402 located outside the rotating plate 4 is connected to a plurality of dredging brushes 403. The storage cavity 405 The inner wall of the storage chamber 405 is fixedly connected to a return spring 4011, one end of the return spring 4011 is fixedly connected to a limit plate 406, a sliding rod 404 is fixedly connected between the limit plate 406 and the sliding plate 402, one side of the limit plate 406 is fixedly connected to a support rod 407, one side of the support rod 407 is fixedly connected to a sliding block 408 that is slidably fitted with the inner wall of the storage chamber 405, and both sides of the storage chamber 405 and the rotating plate 4 are provided with a discharge port 409, and the two discharge ports 409 are connected through a discharge channel 4010;

[0053] The present invention is further specifically described in detail. The limiting plate 406 is slidably fitted with the inner wall of the reservoir chamber 405. The dredging brush 403 is correspondingly arranged with the filter mesh plate and is correspondingly dredging the filter holes opened above it. The interior of the reservoir chamber 405 is located between the limiting plate 406 and its inner wall and is filled with a catalyst. The sliding stopper 408 is correspondingly arranged with the agent outlet 409. The sliding rod 404 slides through the interior of the sliding chamber 401 and the reservoir chamber 405.

[0054] Through the setting of the above technical solution, in specific use:

[0055] When the resin coating inside the anti-corrosion box 1 does not solidify:

[0056] When the resin coating inside the anti-corrosion box 1 is sucked out and sprayed through the filter mesh plate, the suction force above the filter mesh plate is increased accordingly according to the suction action of the suction pump 302. As the stirring plate 206 rotates, the rotating plate 4 drives the dredging brush 403 to rotate to the top of the filter mesh plate. At this time, according to the suction action of the suction pump 302, the dredging brush 403 can be attracted downward, so that the sliding plate 403 drives the dredging brush 403 to extend toward the position of the filter mesh plate, and the dredging brush 403 extends to the filter holes on the filter mesh plate, which can dredge the filter holes on the filter mesh plate, reduce the resin coating adhering to the inside of the filter holes, and improve The transparent effect of the filter holes increases the efficiency of the filter mesh plate in sucking out the resin coating and spraying. At the same time, the rotation of the dredging brush 403 can be used to rotate the bottom end of the dredging brush 403 to remove the resin coating attached to the filter mesh plate, thereby improving the effect of the filter mesh plate in sucking out the resin coating and spraying. At the same time, when the sliding plate 402 drives the sliding rod 404 and the limit plate 406 to slide downward, due to the strong suction force of the suction pump 302, the support rod 407 drives the sliding block 408 to slide to a position that can quickly block the agent outlet 409, so that the catalyst inside the agent storage chamber 405 cannot flow out.

[0057] When the resin coating inside the anti-corrosion box 1 solidifies:

[0058] Since the resin coating of the solidification phenomenon is sucked out by the suction pump 302 with low efficiency, when the rotating plate 4 drives the dredging brush 403 to rotate to the top of the filter mesh plate, due to its small suction force, the sliding plate 402 drives the sliding rod 404 and the limit plate 406 to slide downward, and the support rod 407 drives the sliding block 408 to slide to a position where it cannot block the discharge port 409. At this time, the catalyst inside the storage chamber 405 can flow back and forth to the outside of the rotating plate 4 through the discharge port 409 and the discharge channel 4010. The rotation of the stirring plate 206 can be used to make the catalyst and The resin coating inside the anti-corrosion box 1 is fully mixed to dilute the resin coating that has solidified inside the anti-corrosion box 1. Through the setting of this structure, as the solidification phenomenon of the resin coating intensifies, the suction efficiency of the suction pump 302 for sucking out the resin coating inside the anti-corrosion box 1 is reduced, and the sliding block 408 cannot block the agent outlet 409, so that the catalyst is automatically added, and there is no need for the staff to manually add the catalyst for diluting the resin coating inside the anti-corrosion box 1, thereby improving the work efficiency of the staff in performing anti-corrosion treatment on the outer wall surface of the hydrogen transmission pipeline;

[0059] It should be noted that: a one-way valve that only allows outflow but not inflow is provided inside the outlet 409, which can accordingly prevent the resin coating inside the anti-corrosion box 1 from flowing back into the interior of the storage chamber 405. The interior of the rotating shaft 205 is hollow, and the position of the stirring plate 206 located at the rotating plate 4 is also hollow. The rotating plate 205 and the hollow position inside the stirring plate 206 are connected, and the hollow position inside the stirring plate 206 and the interior of the storage chamber 405 are hollow. One end of the rotating shaft 205 is provided with a feed hole, and the catalyst is added into the interior of the rotating shaft 205 through the feed hole, and accordingly enters the interior of the stirring plate 206 and the storage chamber 405.

[0060] It should be noted that the suction force of the suction pump 302 is greater than the elastic tension of the return spring 4011;

[0061] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
