In addition to being used as pipelines for transporting general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields; pipes for oil heaters, condensers, and coal tar washing oil exchangers in chemical and coking equipment; and pipes for trestle piles and support frames in mine tunnels.

[0003] According to Chinese Patent No. CN213803942U, a steel pipe galvanizing device includes a galvanizing tank, a waste tank fixedly connected to the left side of the galvanizing tank, a waste outlet opened on the upper surface of the connection between the waste tank and the galvanizing tank, a No. 1 motor fixedly installed on the left and right sides of the right side of the galvanizing tank, a drive wheel fixedly connected to the output shaft of the No. 1 motor, a transmission belt movably connected to the drive wheel, a transmission wheel movably connected to the transmission belt, a fixed wheel movably connected to the transmission wheel through the transmission belt, and side slide rails opened on the front and rear sides of the galvanizing tank, with sliding frames movably connected to the side slide rails.

[0004] In the above scheme, the zinc dross on the surface of the galvanizing tank is cleaned by a motor, sliding frame and scraper. This has the following disadvantages: the device cannot clean the zinc dross that settles inside the galvanizing tank during use, causing the zinc dross to settle and accumulate, which reduces the quality of the steel pipe galvanizing process. Utility Model Content

[0005] The purpose of this invention is to provide a steel pipe galvanizing device to solve the problem that the device cannot clean the zinc dross deposited inside the galvanizing tank during use, causing the zinc dross to settle and accumulate, which reduces the quality of the steel pipe galvanizing process.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a steel pipe galvanizing device, comprising an installation box, the installation box being fixed to the top surface of a galvanizing tank, a partition plate being fixed to the inner wall of the galvanizing tank, a rotating hole being provided on the right side of the outer wall of the installation box, a drive motor being fixed to the right side of the outer wall of the installation box, a lead screw being fixed to the output shaft of the drive motor, a movable frame being movably arranged inside the installation box, a threaded hole being provided on one side of the movable frame, the inside of the threaded hole being threadedly connected to the threaded end of the lead screw, an L-shaped scraper being fixed to the bottom surface of the movable frame, a movable groove being provided on the top surface of the galvanizing tank, a hydraulic push rod being fixed to the top surface of the galvanizing tank, a movable block being fixed to one end of the telescopic rod of the hydraulic push rod, the movable block being movably arranged in the movable groove, an installation frame being fixed to the rear side of the movable block, and a filter screen being fixed inside the installation frame.

[0007] Preferably, the top and bottom surfaces of the mounting box are respectively provided with sliding grooves, and the top and bottom surfaces of the movable frame are respectively fixed with sliders, and the two sliders are respectively slidably arranged in the two sliding grooves.

[0008] Preferably, a cleaning brush is fixed to the bottom surface of the L-shaped scraper.

[0009] Preferably, the galvanizing tank is equipped with a collection box inside.

[0010] Preferably, an L-shaped plate is fixed to the top surface of the collection box.

[0011] Preferably, a positioning block is fixed on the inner top surface of the L-shaped plate, and a positioning groove is provided on the top surface of the galvanizing tank, the positioning groove positioning the positioning block.

[0012] Compared with existing technologies, the steel pipe galvanizing device that adopts the above technical solution has the following beneficial effects:

[0013] 1. During use, the drive motor, moving frame, L-shaped scraper, hydraulic push rod, and filter screen facilitate the cleaning of zinc dross and other impurities deposited on the surface and inside of the galvanizing tank, preventing waste from settling and accumulating, keeping the galvanizing tank clean, and ensuring the quality of the galvanizing process.

[0014] Second, during use, the sliding grooves and sliders facilitate the limiting of the moving frame, providing stable support and ensuring its straightness during movement, effectively preventing deviation. Therefore, the L-shaped scraper maintains higher precision and stability when scraping zinc dross and impurities, further improving the cleaning effect. The cleaning brush helps to better scrape away zinc dross and other impurities on the filter screen, ensuring the cleanliness of the filter screen and preventing impurities from re-entering the galvanizing bath or being scraped back.

[0015] Thirdly, during use, the collection box inside the galvanizing tank facilitates the collection of zinc dross and impurities. Under the action of the L-shaped scraper, the zinc dross and impurities are smoothly scraped into the collection box, achieving centralized waste treatment and facilitating subsequent waste processing and recycling. The L-shaped plate design makes it easy to remove the collection box; workers only need to grasp the L-shaped plate to remove the collection box from inside the galvanizing tank, saving manpower and time and reducing operational difficulty. When the collection box is placed inside the galvanizing tank, the positioning block accurately engages in the positioning groove, thus fixing the position of the L-shaped plate and the collection box. This ensures the stability of the collection box inside the galvanizing tank and prevents it from shaking or shifting during operation. Furthermore, the design of the positioning block and positioning groove is simple and practical, easy to install and disassemble, providing convenience for workers. Attached Figure Description

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, a steel pipe galvanizing device includes a mounting box 1, which is fixed to the top surface of a galvanizing tank 2. A partition plate 3 is fixed to the inner wall of the galvanizing tank 2. A rotating hole 4 is opened on the right side of the outer wall of the mounting box 1. A drive motor 5 is fixed to the right side of the outer wall of the mounting box 1. A lead screw 6 is fixed to the output shaft of the drive motor 5. A movable frame 7 is movably arranged inside the mounting box 1. A threaded hole 8 is opened on one side of the movable frame 7. The inside of the threaded hole 8 is threadedly connected to the threaded end of the lead screw 6. An L-shaped scraper 9 is fixed to the bottom surface of the movable frame 7. A movable groove 10 is opened on the top surface of the galvanizing tank 2. A hydraulic push rod 11 is fixed to the top surface of the galvanizing tank 2. A movable block 12 is fixed to one end of the telescopic rod of the hydraulic push rod 11. The movable block 12 is movably arranged in the movable groove 10. A mounting frame 13 is fixed to the rear side of the movable block 12. A filter screen 14 is fixed inside the mounting frame 13.

[0023] During use, the operator starts the drive motor 5, causing the lead screw 6 to rotate, which in turn drives the moving frame 7 and the L-shaped scraper 9 to move to the left inside the galvanizing tank 2. This scrapes away zinc dross and other impurities on the surface of the galvanizing tank 2 and sends them to the left side of the partition plate 3 for subsequent processing. Then, the operator starts the drive motor 5 again, causing the L-shaped scraper 9 to move to the right and reset. Next, the operator starts the hydraulic push rod 11, causing the movable block 12, the mounting frame 13, and the filter screen 14 to move upward, parallel to the top of the partition plate 3. This moves the zinc dross and other impurities deposited inside the galvanizing tank 2 upward. At the same time, the cooperation between the movable block 12 and the movable groove 10 improves the stability of the mounting frame 13 and the filter screen 14 during lifting and lowering. Then, the operator starts the drive motor 5 again, causing the L-shaped scraper 9 to scrape away the zinc dross and other impurities on the filter screen 14 and send them to the left side of the partition plate 3.

[0024] The drive motor 5, moving frame 7, L-shaped scraper 9, hydraulic push rod 11, and filter screen 14 facilitate the cleaning of zinc dross and other impurities deposited on the surface and inside of the galvanizing tank 2, preventing waste from settling and accumulating, keeping the galvanizing tank 2 clean, and ensuring the quality of the galvanizing process.

[0025] like Figures 1-3 As shown, the top and bottom surfaces of the mounting box 1 are respectively provided with sliding grooves 15, and the top and bottom surfaces of the movable frame 7 are respectively fixed with sliders 16, and the two sliders 16 are respectively slidably arranged in the two sliding grooves 15.

[0026] In use, the sliding groove 15 and the slider 16 facilitate the limiting of the moving frame 7, which not only provides a stable support for the moving frame 7, but also ensures its straightness during movement and effectively prevents the occurrence of deviation. Therefore, the L-shaped scraper 9 can maintain higher precision and stability when scraping zinc slag and impurities, further improving the cleaning effect.

[0027] like Figures 1-4As shown, a cleaning brush 17 is fixed to the bottom surface of the L-shaped scraper 9, and a collection box 18 is provided inside the galvanizing tank 2.

[0028] During use, the cleaning brush 17 effectively scrapes away zinc dross and other impurities from the filter screen 14, ensuring its cleanliness and preventing impurities from re-entering the galvanizing bath 2 or being scraped back. The collection box 18 inside the galvanizing bath 2 facilitates the collection of zinc dross and impurities. Under the action of the L-shaped scraper 9, the zinc dross and impurities are smoothly scraped into the collection box 18, achieving centralized waste treatment and facilitating subsequent waste processing and recycling.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, an L-shaped plate 19 is fixed to the top surface of the collection box 18, and a positioning block 20 is fixed to the inner top surface of the L-shaped plate 19. A positioning groove 21 is provided on the top surface of the galvanizing tank 2, and the positioning groove 21 positions the positioning block 20.

[0030] In use, the design of the L-shaped plate 19 facilitates the removal of the collection box 18. Workers can simply grasp the L-shaped plate 19 to remove the collection box 18 from inside the galvanizing tank 2, saving manpower and time while reducing operational difficulty. When the collection box 18 is placed inside the galvanizing tank 2, the positioning block 20 accurately engages with the positioning groove 21, thus fixing the positions of the L-shaped plate 19 and the collection box 18. This ensures the stability of the collection box 18 inside the galvanizing tank 2 and prevents it from shaking or shifting during operation. Furthermore, the design of the positioning block 20 and the positioning groove 21 is simple and practical, easy to install and disassemble, providing convenience for workers.
