Technical Field

[0001] This utility model relates to the field of crystallizer technology, and in particular to a magnetically driven inner wall cleaning device for copper tubes of crystallizers. Background Technology

[0002] The copper tube of the crystallizer is a core component in the continuous casting process of steel. It is installed inside the crystallizer of the continuous casting machine and comes into direct contact with the high-temperature molten steel.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] The crystallizer copper tube magnetic drive inner wall cleaning device disclosed in this utility model is mainly used in scenarios where the copper tube has a special shape with a certain curvature, and multiple adjustments are required during cleaning, which is inconvenient to operate and easy to scratch the inner wall of the copper tube due to insufficient mechanical adjustment precision.

[0039] Reference Figures 1-6 A magnetically driven inner wall cleaning device for a crystallizer copper tube, comprising:

[0040] Support frame 1, crystallizer body 2 is provided on support frame 1, and copper tube body 4 is provided inside crystallizer body 2;

[0041] Four suction cup components 7 are all located on the top of the crystallizer body 2, and the same mounting bracket 6 is fixedly connected to the four suction cup components 7.

[0042] The magnetic drive cleaning module 3 is mounted on the mounting bracket 6. The magnetic drive cleaning module 3 is used to improve the cleaning efficiency of the inner wall of the copper tube and ensure that the inner wall of the copper tube is not damaged during cleaning, thereby increasing the service life of the equipment.

[0043] The slag collection module 5 is located at the bottom of the copper tube body 4. The slag collection module 5 is used to collect the cleaned slag to prevent the slag from scattering and causing adverse effects.

[0044] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, the magnetic drive cleaning module 3 includes:

[0045] The toothed ring swivel 307 is mounted on the mounting bracket 6. Four guide rods 306 are provided through the inside of the toothed ring swivel 307. The same mounting plate frame 301 is provided at both ends of the four guide rods 306.

[0046] A stepper motor 302 is mounted on the top of one of the mounting frames 301. The output shaft of the stepper motor 302 is connected to a linear lead screw 305 via a coupling. The bottom end of the linear lead screw 305 is located on the top of the mounting frame 301.

[0047] In this utility model, the magnetic drive cleaning module 3 also includes:

[0048] The drive motor 304 is mounted on the mounting bracket 6. The output shaft of the drive motor 304 is connected to the drive gear 303 via a coupling. The drive gear 303 meshes with the gear ring 307.

[0049] Cleaning plate holder 310 is mounted on linear lead screw 305 and four guide rods 306. A magnetic ring power supply 308 is mounted on the top of cleaning plate holder 310.

[0050] In this utility model, the magnetic drive cleaning module 3 also includes:

[0051] Four guide frames 312 are provided on the cleaning plate base 310, and magnetic blocks 315 are movably connected to the inner walls of the four guide frames 312.

[0052] Four electromagnets 311 are provided on the cleaning plate base 310, and the four electromagnets 311 are located at one end of the four guide sleeves 312 respectively.

[0053] In this utility model, the magnetic drive cleaning module 3 also includes:

[0054] Four connecting lines 309, one end of each of the four connecting lines 309 is fixedly connected to the bottom end of the magnetic ring power supply 308, and the other end of each of the four connecting lines 309 is respectively set on four electromagnets 311.

[0055] Four cleaning motors 314 are respectively set at one end of four magnetic blocks 315. The output shafts of the four cleaning motors 314 are all connected to cleaning brushes 313 through couplings. The cleaning brushes 313 are used to clean the molten slag.

[0056] It should be noted that electromagnet 311 and magnetic block 315 interact magnetically to achieve non-contact position adjustment, allowing the cleaning brush 313 to automatically adjust its position. This eliminates the need for multiple adjustments for the curved shape of the copper tube, increasing ease of operation and improving cleaning efficiency. Furthermore, the magnetic force between electromagnet 311 and magnetic block 315 during adjustment prevents excessive pressure between the cleaning brush 313 and the inner wall of the copper tube, thus avoiding damage during cleaning and ensuring the device's lifespan.

[0057] Reference Figure 2 , Figure 3 and Figure 6 In a preferred embodiment, the slag collection module includes:

[0058] A fixed rod base 505 is located at the bottom of one of the mounting plate frames 301. A magnetic block 506 is installed inside the fixed rod base 505. Four connecting cables 502 are installed at the bottom of the magnetic block 506. One end of each of the four connecting cables 502 is provided with a connecting ring.

[0059] A magnetic power supply 503 is mounted on one of the mounting frames 301. An electromagnet 504 is mounted at the bottom of the magnetic power supply 503 and is located inside the fixed rod seat 505.

[0060] In this utility model, the slag collection module also includes:

[0061] Four opening and closing rods 507 are provided, all of which are mounted on fixed rod bases 505. A soft guide plate 501 is fixedly connected to one side outer wall of each of the four opening and closing rods 507. The one side outer wall of each of the four soft guide plates 501 is respectively mounted on the side wall of the adjacent opening and closing rods 507. Four connecting rings are respectively mounted on the four opening and closing rods 507.

[0062] A collection bucket frame 508 is provided at the bottom end of a fixed rod base 505.

[0063] It should be noted that the slag collection module can collect the cleaned slag during use, thereby preventing the slag from falling directly to the bottom after cleaning. This ensures that the slag will not cause adverse effects due to scattering, thus increasing the effectiveness of the device. At the same time, collecting the slag can also reduce the workload of workers.

[0064] Working principle: When in use, the device is placed inside the copper tube body 4, and the mounting bracket 6 is fixed above the crystallizer body 2 by the suction cup component 7;

[0065] During cleaning, the magnetic ring power supply 308 is activated, driving electromagnet 311 through connection line 309. This generates a magnetic force between electromagnet 311 and magnetic block 315, which in turn causes magnetic block 315 to move cleaning motor 314 and cleaning brush 313 until cleaning brush 313 contacts the inner wall of the copper tube. At this time, cleaning motor 314 runs, driving cleaning brush 313 to clean. Simultaneously, stepper motor 302 and drive motor 304 run. Stepper motor 302 drives linear lead screw 305 to rotate, and drive motor 304 drives drive gear 303 and gear ring 307 to rotate, causing cleaning plate base 310 to rotate until cleaning is completed.

[0066] During the collection operation, the magnetic power supply 503 is de-energized, causing the electromagnet 504 and the magnetic block 506 to lose their magnetic force, which in turn causes the magnetic block 506 to fall. At this time, since the opening and closing rod 507 is hinged to the bottom of the fixed rod seat 505, the opening and closing rod 507 unfolds under the action of gravity, which in turn unfolds the soft guide plate 501 to guide the molten slag, so that the molten slag falls into the collection hopper frame 508 for collection and concentration.

[0067] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
