Description

Technical Field

[0001] The utility model relates to the technical field of rust prevention treatment, and particularly to an anti-rust treatment device for steel pipes. Background Art

[0002] Rusting is a chemical reaction. The most common rusting phenomenon is that iron products are exposed to air for a long time and undergo an oxidation reaction with oxygen, or are eroded by oxygen elements in water to become oxides. Port machinery is more likely to rust because it operates near the sea for a long time. During the construction and maintenance of ports, docks, bridges, ships and other facilities, steel pipes are essential. Steel pipes can be used to construct pillars, pipelines, guardrails and other structures in port facilities. In addition, steel pipes can also be used for transporting and storing liquids or gases, such as oil, natural gas, etc., which may be related to ports.

[0003] Due to the high humidity and salt content in the air of the port, the surface of the steel pipe will rust faster. The existing solutions generally use a steel pipe rust remover to treat the rust on the surface of the steel pipe. After rust removal, the steel pipes are directly stacked together, and workers manually brush anti-rust paint on the surface of the steel pipes for anti-rust treatment. Since the efficiency of manual painting is low, it will be too late to perform anti-rust treatment on the steel pipes after rust removal, resulting in the steel pipes being exposed to the air. Especially in the humid environment of the port, the steel pipes are likely to rust again, reducing their strength and durability, and thus shortening their service life.

[0034] The present utility model will be further described below with reference to the accompanying drawings.

[0035] The present utility model provides a rust-proof treatment device for steel pipes, which can timely perform painting and rust-proof treatment on the surface of the steel pipes after rust removal, avoid the problem that the surface of the steel pipes rusts again due to the stop of operation or slow manual efficiency after rust removal, and improve the corrosion resistance and service life of the steel pipes.

[0036] Figure 1 It is a schematic structural diagram of the rust-proof treatment device for steel pipes in an embodiment of the present application; Figure 2It is a schematic structural diagram of an anti-rust treatment device for steel pipes in another embodiment of the present application. As Figure 1-2 shown, an embodiment of the present application provides an anti-rust treatment device 1000 for steel pipes. The anti-rust treatment device 1000 for steel pipes includes a painting component 100, a rust removal component 200, and a pipe feeding component 300. The painting component 100 includes a first annular channel 110. The first annular channel 110 is configured to perform painting treatment on the surface of the steel pipe after rust removal. The rust removal component 200 is disposed upstream of the painting component 100. The rust removal component 200 includes a second annular channel 210. The second annular channel 210 is coaxially arranged with the first annular channel 110, and the second annular channel 210 is configured to perform rust removal treatment on the surface of the steel pipe. The pipe feeding component 300 is disposed upstream of the rust removal component 200. The pipe feeding component 300 is configured to axially pass the steel pipe to be rust removed through the second annular channel 210 and the first annular channel 110 in sequence.

[0037] It should be noted that the pipe feeding component 300 is disposed upstream of the rust removal component 200, which can be understood as that the pipe feeding component 300 first conveys the steel pipe to the rust removal component 200 for rust removal treatment. Similarly, the painting component 100 is disposed downstream of the rust removal component 200, which can be understood as that after the rust removal component 200 finishes the rust removal treatment on the steel pipe, the steel pipe enters the painting component 100 for painting treatment.

[0038] It can be understood that when the pipe feeding component 300 moves the steel pipe axially so that the steel pipe passes through the second annular channel 210 of the rust removal component 200 for rust removal treatment, the pipe feeding component 300 continuously moves the steel pipe axially so that the rust-removed part of the steel pipe passes through the first annular channel 110 of the painting component 100, and the first annular channel 110 performs painting treatment on the rust-removed surface of the steel pipe. While the part of the steel pipe that has not completed rust removal continues to move axially and passes through the second annular channel 210 for rust removal treatment, the part of the steel pipe that has completed rust removal moves axially and passes through the first annular channel 110 of the painting component 100 for painting treatment, so that the painting treatment can be carried out in time after the rust removal treatment on the surface of the steel pipe is completed.

[0039] It should be noted that the "upstream" and "downstream" mentioned above and below in the present application refer to the sequence of the production of the anti-rust treatment device 1000 for steel pipes, rather than limiting the spatial positions between the components.

[0040] The rust prevention treatment device 1000 for steel pipes according to an embodiment of the present application. The pipe feeding component 300 disposed upstream of the rust removal component 200 can axially pass the steel pipe to be rust removed through the second annular channel 210 of the rust removal component 200, so that the second annular channel rusts the surface of the steel pipe. When the rust removal component 200 rusts the surface of the steel pipe passing through the second annular channel 210, during the process of the rust removal component 200 rust removing the surface of the steel pipe, the pipe feeding component 300 continuously moves the steel pipe along its axis, so that the rust removed part of the steel pipe can pass through the first annular channel 110 of the painting component 100 disposed downstream of the rust removal component 200, so that the surface of the rust removed steel pipe can be painted in time, avoiding the problem that the surface of the steel pipe rusts again due to stopping operation or slow manual efficiency after rust removal, and improving the corrosion resistance and service life of the steel pipe.

[0041] As Figure 1-2 shown, in some optional embodiments, the rust prevention treatment device 1000 for steel pipes further includes a machine body 900. A workbench 910 is provided on the machine body 900. The pipe feeding component 300, the rust removal component 200, and the painting component 100 are all disposed on the workbench 910.

[0042] As Figure 1-2 shown, in some embodiments, the rust prevention treatment device 1000 for steel pipes further includes a guiding component 800. The guiding component 800 is installed on the workbench 910. The guiding component 800 is disposed downstream of the drying component 700. The guiding component 800 includes two first supports 810. The two first supports 810 are spaced apart along the second direction Y. Each first support 810 is provided with a first guiding wheel 820.

[0043] In this embodiment, after the anti-rust paint on the surface of the steel pipe is air-dried, the pipe feeding component 300 transports the steel pipe between the two first guiding wheels 820. During the process of transporting the steel pipe, due to the friction force between the steel pipe and the two first guiding wheels 820, the two first guiding wheels 820 rotate relative to the corresponding first supports 810, so that the steel pipe is safely exported, enabling the rust prevention treatment device 1000 of the steel pipe to continuously perform rust prevention treatment on other steel pipes that need rust prevention treatment, maintaining the continuity of the work process, avoiding time waste caused by stopping operation, and thus improving work efficiency.

[0044] As Figure 2 shown, and referring to Figure 5, in some alternative embodiments, an accommodation chamber is provided inside the machine body 900. The workbench 910 is provided with a third opening communicating with the accommodation chamber. The fixing base 220 is disposed above the third opening, and the first opening of the conical cylinder 400 corresponds to the third opening of the workbench 910. When the steel pipe is derusted by the derusting assembly 200, the rust removed from the surface of the steel pipe enters the conical cylinder 400 through the third opening provided at the position corresponding to the fixing base 220 below the workbench 910 and the first opening of the conical cylinder 400. Under the guiding action of the conical cylinder 400, it falls into the collection drawer 600 of the collection frame 500 through the second opening of the conical cylinder 400 for collection, preventing it from scattering on the workbench 910 to become waste, which is beneficial to keeping the workplace clean.

[0045] In some alternative embodiments, a maintenance door is further provided on the side wall of the machine body 900. The maintenance door is rotatably mounted on the machine body 900 through a hinge, and the rust collected in the collection drawer 600 in the accommodation chamber of the machine body 900 can be processed through the maintenance door. Further, a plurality of walking wheels are provided at the bottom of the machine body 900, enabling the machine body 900 to move freely through the walking wheels.

[0046] As Figure 3 shown, and referring to Figure 1-2 , in some embodiments, the first annular channel 110 includes an annular pipe body 111. A plurality of nozzles 112 communicating with the annular pipe body 111 are provided along the circumferential direction of the inner side wall of the annular pipe body 111. The painting assembly 100 further includes a first air pump 120, a first pipe body 130, and a second pipe body 140. One end of the first pipe body 130 is communicated with the first air pump 120, and the other end of the first pipe body 130 is communicated with the first annular pipe body 111. One end of the second pipe body 140 is communicated with the first pipe body 130, and the other end of the second pipe body 140 is used to connect to an anti-rust paint supply device.

[0047] It should be noted that the pipe feeding assembly 300 can send the steel pipe with surface derusting completed to the axis of the first annular channel 110 of the painting assembly 100.

[0048] In this embodiment, the first air pump 120 sends high-pressure gas into the first pipe body 130. When the high-pressure gas enters the annular pipe body 111 from the first pipe body 130, it can bring the anti-rust paint inside the second pipe body 140 into the first pipe body 130 and send it into the annular pipe body 111. Then, under the action of the high-pressure gas pressure, the anti-rust paint is sprayed onto the surface of the steel pipe through the nozzles 112 provided on the inner side wall of the annular pipe body 111. After the derusted steel pipe is sprayed with a layer of anti-rust paint, the surface of the steel pipe can be timely rust-proofed, avoiding the problem that the surface of the steel pipe rusts again due to slow manual efficiency. The anti-rust paint can form a protective film, effectively isolating the erosion of air, water, and other corrosive substances on the steel pipe, thereby improving the corrosion resistance of the steel pipe.

[0049] In some alternative embodiments, a plurality of spray nozzles 112 communicating with the annular pipe body 111 are circumferentially arranged on the inner side wall of the annular pipe body 111, and the plurality of spray nozzles 112 are arranged at equal intervals along the circumference of the inner side of the annular pipe body 111, so that the painting assembly 100 can evenly paint the surface of the steel pipe.

[0050] As Figure 3 shown and referring to Figure 1-2 In some embodiments, the painting assembly 100 further includes a splash-proof sleeve 150. The outer wall of the annular pipe body 111 is fixedly connected to the inner wall of the splash-proof sleeve 150, and the first pipe body 130 passes through the side wall of the splash-proof sleeve 150 and communicates with the annular pipe body 111.

[0051] In this embodiment, after the surface of the steel pipe is derusted, the pipe feeding assembly 300 axially transports the steel pipe into the splash-proof sleeve 150 and passes through the axis of the annular pipe body 111 provided on the inner wall of the splash-proof sleeve 150. The plurality of spray nozzles 112 provided inside the annular pipe body 111 spray paint on the surface of the derusted steel pipe. During the painting process, the anti-rust paint that cannot be sprayed onto the surface of the steel pipe is sprayed onto the inner wall of the splash-proof sleeve 150 due to the protection of the splash-proof sleeve 150, effectively preventing the spray nozzles 112 provided inside the annular pipe body 111 from spraying the anti-rust paint on the workbench 910 or scattering it in the air during painting, and effectively avoiding the pollution of the external environment by the anti-rust paint.

[0052] As Figure 3 shown and referring to Figure 1-2 In some embodiments, the painting assembly 100 further includes a scraping ring 160 and a connecting rod 170. The scraping ring 160 is arranged on the side of the splash-proof sleeve 150 facing away from the derusting assembly 200. The scraping ring 160 is coaxially arranged with the splash-proof sleeve 150. One end of the connecting rod 170 is connected to the splash-proof sleeve 150, and the other end of the connecting rod 170 is connected to the scraping ring 160.

[0053] In this embodiment, a scraping ring 160 is coaxially arranged on the side of the splash-proof sleeve 150 facing away from the derusting assembly 200. The scraping ring 160 is connected to the splash-proof sleeve 150 through the connecting rod 170. The diameter of the scraping ring 160 is slightly larger than the outer diameter of the steel pipe. After the painting of the steel pipe is completed, under the transportation of the pipe feeding assembly 300, the steel pipe enters the scraping ring 160 from the splash-proof sleeve 150. During the process of the steel pipe passing through the scraping ring 160, the scraping ring 160 can scrape off the thicker paint film on the surface of the steel pipe to prevent the paint film on the surface of the steel pipe from being uneven during the painting process.

[0054] As Figure 3 shown and referring to Figure 1-2, in some alternative embodiments, the fixing base 220 is fixed on the workbench 910. The fixing base 220 includes a first fixing disk 221, a second fixing disk 222, and a connecting column 223. The first fixing disk 221 and the second fixing disk 222 are coaxially arranged at intervals through the connecting column 223. Rotating notches are provided on the opposite sides of the first fixing disk 221 and the second fixing disk 222. The toothed ring is rotatably arranged between the first fixing disk 221 and the second fixing disk 222. The wall of the annular sleeve 211 in the toothed ring extends axially and is rotatably connected to the notch provided on the first fixing disk 221 and the notch provided on the second fixing disk 222.

[0055] Further, a plurality of balls are provided between the rotating notch and the outer side of the wall of the annular sleeve 211, so that the annular sleeve 211 rotates inside the rotating notch through the balls, and the balls are used to reduce the friction when the annular sleeve 211 rotates and reduce the wear of the annular sleeve 211 in the toothed ring.

[0056] In some alternative embodiments, the second fixing disk 222 is arranged on the side of the fixing base 220 facing the painting assembly 100. A brush M is installed on the inner wall of the second fixing disk 222. The brush M can clean the surface of the steel pipe after the surface rust removal by the scraper 213 and before painting, so that some rust adhering to the surface of the steel pipe after rust removal is cleaned, which is convenient for the subsequent painting assembly to paint the surface of the steel pipe.

[0057] As Figure 4 shown, and referring to Figure 1-2 , in some embodiments, the second annular channel 210 includes an annular sleeve 211, gear teeth 212, and a scraper 213. The gear teeth 212 are arranged on the outer wall of the annular sleeve 211, and the scraper 213 is arranged on the inner wall of the annular sleeve 211. The rust removal assembly 200 further includes a fixing base 220, a driving gear 230, and a first driving device 240. The annular sleeve 211 is rotatably installed on the fixing base 220. The driving gear 230 is meshed with the gear teeth 212, and the first driving device 240 is connected to the driving gear 230.

[0058] In this embodiment, the pipe feeding assembly 300 can convey the steel pipe to be rust removed and pass it through the axis of the annular sleeve 211. The first driving device 240 of the rust removal assembly 200 can drive the driving gear 230 to rotate. Since the driving gear 230 is meshed with the gear teeth 212 arranged on the outer wall of the annular sleeve 211, the annular sleeve 211 can rotate synchronously with the driving gear 230. Since the scraper 213 is arranged on the inner wall of the annular sleeve 211, during the rotation of the annular sleeve 211, the scraper 213 can scrape the rust on the surface of the steel pipe.

[0059] As Figure 5 shown, and referring to Figure 2, in some embodiments, the rust prevention treatment device 1000 for steel pipes further includes a conical cylinder 400, a collection frame 500, and a collection drawer 600. The conical cylinder 400 is disposed below the second annular channel 210. The conical cylinder 400 has a first opening and a second opening that are axially connected to each other. The opening area of the first opening is larger than that of the second opening, and the first opening faces the second annular channel 210. The second opening is communicated with the collection drawer 600, and the collection drawer 600 is slidably disposed in the collection frame 500.

[0060] It should be noted that the collection drawer 600 is slidably disposed in the collection frame 500, specifically meaning that a slide rail is fixedly connected to the inner bottom surface of the collection frame 500, and the collection drawer 600 is slidably connected above the slide rail through a slider. The collection drawer 600 can be taken out of the collection frame 500 along the slide rail.

[0061] In this embodiment, when the steel pipe passes through the second annular channel 210 for rust removal treatment, the rust removed from the surface of the steel pipe falls into the conical cylinder 400 through the first opening of the conical cylinder 400, and falls into the collection drawer 600 of the collection frame 500 through the second opening of the conical cylinder 400 for collection. After the collection is completed, the collection drawer 600 is taken out of the collection frame 500 along the slide rail, and the collected rust is recycled and reused. The scraped rust can be used as an iron source and can be reused after appropriate treatment, reducing the demand for new iron ore and being beneficial to resource conservation and environmental protection.

[0062] As shown in FIG. 5, in some embodiments, the first driving device 240 includes a driving motor 241 and a rotating shaft 242. The driving gear 230 is disposed in the conical cylinder 400, and the rotating shaft 242 passes through the conical cylinder 400 and is fixedly connected to the driving gear 230.

[0063] The driving motor 241 is connected to the driving gear 230 through the rotating shaft 242. The driving motor 241 can drive the rotating shaft 242 to rotate and then drive the driving gear 230 to rotate. Since the driving gear 230 is arranged inside the conical cylinder 400, the rotating shaft 242 penetrates through the conical cylinder 400 and is connected to the driving gear 230. Since the driving gear 230 is meshed and connected with the teeth 212 arranged on the outer wall of the annular sleeve 211, the toothed ring can rotate synchronously with the driving gear 230. Since the inner wall of the annular sleeve 211 is provided with a scraping blade 213, during the rotation of the annular sleeve 211, the scraping blade 213 can scrape the rust on the surface of the steel pipe. The scraped rust is introduced into the collection drawer 600 of the collection frame 500 by the conical cylinder 400. Since the rotating shaft 242 passes through the conical cylinder 400 and is connected to the driving gear 230 arranged inside the conical cylinder 400, the rotating shaft 242 can stir the rust falling into the conical cylinder 400, so that the rust can be accelerated to fall into the collection drawer 600 of the collection frame 500 from the conical cylinder 400, avoiding the rust falling into the conical cylinder 400 from accumulating in the conical cylinder 400 and being unable to fall into the collection drawer 600 of the collection frame 500.

[0064] As Figure 6 shown, and referring to Figure 1-2 , in some embodiments, the pipe feeding assembly 300 includes at least two sub-components 310, a transmission assembly 320, and a second driving device 330. The sub-components 310 are arranged at intervals along the first direction X. Each sub-component 310 includes two support seats 311 and two guide rollers 312. The two support seats 311 are symmetrically and spaced apart along the second direction Y. The two guide rollers 312 are symmetrically and spaced apart along the third direction Z and are connected between the two support seats 311. One end of the guide roller 312 of one sub-component 310 is connected to the second driving device 330, and the other end of the guide roller 312 is connected to the same-side end of the guide roller 312 in the adjacent sub-component 310 through the transmission assembly 320.

[0065] It should be noted that the sub-component 310 connected to the second driving device 330 is arranged upstream of the other sub-components 310. When the steel pipe is inserted between the two guide rollers 312 arranged in the sub-component 310 connected to the second driving device 330, since the second driving device 330 can drive one of the guide rollers 312 in one sub-component 310 to rotate, due to the frictional force between the guide roller 312 and the steel pipe, the other guide roller 312 in the same sub-component 310 can also rotate relative to the support seat 311.

[0066] In this embodiment, after inserting the steel pipe to be derusted between the two guide rollers 312 arranged between the two support seats 311 of each sub-component 310, the guide rollers 312 connected to the second driving device 330 rotate driven by the second driving device 330. Due to the frictional force between the guide rollers 312 and the steel pipe, the other guide roller 312 in the same sub-component 310 is driven to rotate, so that the steel pipe can move along its own axial direction. At the same time, since one end of the guide roller 312 is connected to the second driving device 330, and the other end of the guide roller 312 is connected to the same-side end of the guide roller 312 in the adjacent sub-component 310 through the transmission component 320, the second driving device 330 can drive one guide roller 312 in two sub-components 310 to rotate at the same time, so that the pipe feeding component 300 can convey the steel pipe more smoothly.

[0067] In some alternative embodiments, the sub-component 310 connected to the second driving device 330 is arranged upstream of other sub-components 310, so that the steel pipe can move better along the axial direction.

[0068] As Figure 7 shown, refer to Figure 1-2 , in some embodiments, the rust prevention treatment device 1000 for the steel pipe further includes a drying component 700. The drying component 700 is arranged downstream of the painting component 100. The drying component 700 includes a third annular channel 710, and the third annular channel 710 is coaxially arranged with the first annular channel 110. The third annular channel 710 is configured to dry the surface of the painted steel pipe.

[0069] In this embodiment, the steel pipe after being sprayed with rust prevention paint is continuously sent into the drying component 700 by the pipe feeding component 300. The steel pipe passes through the third annular channel 710 of the drying component 700, and the third annular channel 710 dries the rust prevention paint on the surface of the steel pipe, ensuring that the rust prevention paint is fully dried and cured. The fully dried rust prevention paint can adhere more firmly to the surface of the steel pipe, forming a strong protective film, improving the protection effect of the rust prevention paint on the surface of the steel pipe, effectively preventing damage and corrosion to the steel pipe caused by external factors, improving the durability and use effect of the steel pipe, and thus effectively extending the service life of the steel pipe.

[0070] It should be noted that the third annular channel 710 can dry the rust prevention paint on the surface of the steel pipe by arranging an annular air duct 711, or it can be an annular heating pipe, and the rust prevention paint on the surface of the steel pipe passing through the third annular pipe is heat-treated to ensure that the rust prevention paint is fully dried and cured. The specific structure of the third annular channel 710 is not limited in this embodiment.

[0071] As Figure 7 shown, refer to Figure 1-2, in some embodiments, the third annular channel 710 includes an annular air duct 711 and a second air pump 712. A plurality of air outlets K are circumferentially arranged on the inner sidewall of the annular air duct 711, and the second air pump 712 is communicated with the annular air duct 711.

[0072] In this embodiment, the second air pump 712 is started. The second air pump 712 blows gas into the annular air duct 711, and then the gas is blown out through the plurality of air outlets K arranged on the inner sidewall of the annular air duct 711 to air-dry the rust-proof paint on the surface of the steel pipe, so as to ensure that the rust-proof paint is fully dried and cured, so that the rust-proof paint can adhere more firmly to the surface of the steel pipe, forming a solid protective film, and improving the protection effect of the rust-proof paint on the surface of the steel pipe.

[0073] Furthermore, the plurality of air outlets K arranged on the inner wall of the annular air duct 711 are uniformly distributed along the circumference of the annular air duct 711, so that the rust-proof paint on the surface of the steel pipe can be air-dried evenly.

[0074] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components thereof can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
