[0002] In the manufacturing process of steel pipes, heat treatment is an important link, which can improve the mechanical properties and corrosion resistance of steel pipes. However, a layer of iron oxide scale will be formed on the surface of the steel pipe during the heat treatment process, which will not only affect the appearance quality of the steel pipe, but may also have an adverse effect on subsequent processing and use.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The steel pipe heat treatment iron oxide scale blowing device, when conveying the steel pipe to the inner wall of the stepping beam, sends a signal through the controller, so that the power output shafts at both ends of the dual-rotor motor rotate simultaneously after receiving the signal, and the screw is driven to rotate by the power output shaft at one end, so that the power output shaft at the other end of the dual-rotor motor drives the rotating block 1 to rotate, and during the rotation of the rotating block 1, the tension of the tension belt rotates due to the tension of the tension belt, so that the tension belt drives the rotating block 2 to rotate, and the rotating rod and another screw are driven to rotate by the rotating block 2, so that the moving block drives the steel brush to move on the outer wall of the screw, and the iron filings on the top of the steel pipe are scraped and cleaned by the steel brush.

[0022] It should be noted that in the process of conveying the steel pipe to the inner wall of the stepping beam 7, a signal is sent through the controller 13, so that the power output shafts at both ends of the dual-rotor motor 3 rotate synchronously after receiving the signal, and the power output shaft at one end drives the screw 4 to rotate, thereby pushing the power output shaft at the other end of the dual-rotor motor 3 to drive the rotating block 18 to rotate. Due to the tension of the tension belt 19, it drives the tension belt 19 to rotate during the rotation process, thereby driving the rotating block 20 to rotate, and then the rotating rod 21 and the other screw 4 are driven to rotate by the rotating block 20, so that the moving block 5 drives the steel brush 6 to move on the outer wall of the screw 4, and the steel brush 6 is used to scrape and clean the iron filings on the top of the steel pipe. At the same time, when the steel pipe moves out of the equipment, the iron filings on both sides of the steel pipe are cleaned by the steel plate 10, thereby cleaning the surface of the steel pipe.

[0023] In a preferred embodiment, a threaded groove 16 is provided on the outer wall of the placement rack 1, a bolt 14 is threadedly connected to the inner wall of the threaded groove 16, a nut 15 is threadedly connected to the end of the bolt 14, a movable groove 17 is provided on the inner wall of the placement rack 1, a collection shell 8 is slidably connected to the inner wall of the movable groove 17, and a pull block 12 is fixedly assembled on the outer wall of the collection shell 8.

[0024] It should be noted that, through the operation of the steel brush 6, the scraped iron chips are guided to the inner wall of the collecting shell 8 for collection. At the same time, through the guiding effect of the guide block 11, the iron chips scraped from the steel plate 10 slide along the inner wall of the guide block 11 into the collecting shell 8. This process realizes the effective collection of iron chips. When the iron chips inside the collecting shell 8 are close to full load, the staff operates the bolt 14 to rotate it to disengage it from the nut 15 and the inner wall of the thread groove 16. Then, by pulling the pulling block 12, it generates traction on the collecting shell 8, so that the collecting shell 8 slides out from the inner wall of the movable groove 17. This design enables the collecting shell 8 to be quickly loaded and unloaded, which is convenient for cleaning iron chips.

[0025] In a preferred embodiment, the thread groove 16 passes through the outer wall of the collecting shell 8 , and the rotating rod 21 is fixedly assembled with the screw rod 4 .

[0026] It should be noted that the threaded groove 16 passes through the outer wall of the collection shell 8, so that the bolt 14 and the nut 15 are threadedly connected to fix the collection shell 8 to prevent the collection shell 8 from moving out from the inner wall of the placement rack 1 during operation, and the rotating rod 21 drives another set of screws 4 to rotate.

[0027] In a preferred embodiment, the dual-rotor motor 3 is electrically connected to the controller 13 , and the tension belt 19 is tightly fitted to the inner walls of the second rotating block 20 and the first rotating block 18 .

[0028] It should be noted that the controller 13 sends a signal, so that the device works after receiving the signal, and the tension belt 19 fits with the rotating block 20 and the rotating block 1 18, so that the rotating block 18 will drive the tension belt 19 and the rotating block 2 20 to rotate during the rotation process.

[0029] In a preferred embodiment, the guide block 11 is adapted to the inner wall of the placement rack 1 , and the collection shell 8 is adapted to the inner wall of the moving groove 17 .

[0030] It should be noted that, by adapting the guide block 11 to the inner wall of the placement rack 1, when the guide block 11 guides the iron filings to the inner wall of the collection shell 8, the iron filings will not fall from the top of the guide block 11 and fall to the ground. By adapting the collection shell 8 to the movable groove 17, the collection shell 8 will not get stuck during the movement.

[0031] In a preferred embodiment, the number of each of the fixed rod 2 , the screw rod 4 and the moving block 5 is two, and the two fixed rods 2 , the screw rod 4 and the moving block 5 are respectively located at the top of the placement rack 1 .

[0032] It should be noted that, through the two fixed rods 2, the screw rod 4 and the moving block 5, the steel brush 6 is more stable during the movement and will not tilt, resulting in the inability to accurately scrape off the iron filings on the top of the steel pipe.

[0033] Working principle: in the process of conveying the steel pipe to the inner wall of the walking beam 7, a signal is sent through the controller 13, so that the power output shafts at both ends of the dual-rotor motor 3 rotate synchronously after receiving the signal, and the power output shaft at one end drives the screw 4 to rotate, thereby pushing the power output shaft at the other end of the dual-rotor motor 3 to drive the rotating block 18 to rotate. On this basis, the tension of the tension belt 19 is used when the rotating block 18 rotates to rotate the tension belt 19, thereby driving the rotating block 20 to rotate, and the rotating rod 21 and the other screw 4 are connected to rotate through the rotating block 20, so that the moving block 5 drives the steel brush 6 to move on the outer wall of the screw 4, and the steel brush 6 scrapes off the iron filings on the top of the steel pipe and Cleaning is carried out. At the same time, when the steel pipe moves out of the equipment, the steel plate 10 is used to clean the iron chips on both sides of the steel pipe to achieve comprehensive cleaning of the steel pipe surface. The scraped iron chips are guided to the inner wall of the collecting shell 8 by the steel brush 6 for collection, and the iron chips scraped off by the steel plate 10 are guided by the guide block 11 to slide from the inner wall of the guide block 11 to the inner wall of the collecting shell 8 to achieve the collection of iron chips. When the iron chips in the collecting shell 8 are almost full, the staff rotates the bolt 14 to rotate it out from the nut 15 and the inner wall of the thread groove 16, and generates tension on the collecting shell 8 by pulling the pull block 12, so that the collecting shell 8 slides out from the inner wall of the moving groove 17, thereby achieving rapid loading and unloading and cleaning of the collecting shell 8.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood 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 present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
