[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the steel smelting process, the ladle is a container for holding high-temperature molten steel. During the pouring process of the molten steel, some slag often remains on the inner wall of the ladle. These residual slag not only affects the service life of the ladle, but may also cause the quality of the molten steel to deteriorate. Existing slag removal methods are mostly manual operations, which are inefficient and have safety hazards. Therefore, it is necessary to develop an automated and efficient slag removal device to improve the slag removal efficiency and ensure operational safety, and to avoid contaminating the molten steel when the next batch of molten steel of different steel grades is loaded.

[0032] Embodiment 1:

[0033] Since manual cleaning is not only time-consuming and laborious, but also poses a safety hazard, it may cause the slag in the ladle to not be cleaned up, affecting the subsequent smelting process and molten steel quality. In order to solve the above problems, combined with Figure 1-Figure 4 As shown, the present invention provides an automatic rotary slag scraping device for efficiently removing slag in a ladle, comprising a vehicle body 100 as a carrier of the entire device, the vehicle body 100 is provided with a slag scraping mechanism 200 for cleaning ladles of different sizes, the vehicle body 100 is provided with a pushing mechanism 300 for guiding the slag in the ladle, and can automatically remove the slag attached to the inner wall after the molten steel is poured from the ladle, thereby improving the slag cleaning efficiency, reducing labor intensity, ensuring the clean use of the ladle, and ensuring safe operation.

[0034] If the scraper 205 cannot make good contact with the inner wall of the ladle, the cleaning time will be extended because the operator may need to adjust the position several times, or find an area that is not cleaned after cleaning, resulting in rework and reducing the overall work efficiency. In order to solve the above problems, the scraper mechanism 200 includes a motor 201 fixedly mounted on the vehicle body 100, a transmission shaft 202 is provided on the output end of the motor 201, a transmission block 207 is mounted on the transmission shaft 202, a connecting block 203 is fixedly connected to the end of the transmission shaft 202, and a plurality of transmission sleeves 207 are hinged on the connecting block 203. 04. A scraper 205 is provided on the transmission sleeve 204. A hydraulic telescopic rod 208 for adjusting the angle of the scraper 205 is hinged between the transmission block 207 and the transmission sleeve 204. When scraping slag from ladles of different sizes, the hydraulic telescopic rod 208 is started to extend or retract its free end, and then the transmission sleeve 204 can be pulled or pushed. The scraper 205 moves with the transmission sleeve 204, and the angle of the scraper 205 is adjusted to adapt to the inner walls of ladles of different sizes. An adjusting component 206 for driving the scraper 205 to contact the inner walls of ladles of different sizes is provided on the connecting block 203.

[0035] Specifically, the output end of the motor 201 is fixedly connected with a sliding sleeve 209 which is slidably connected to the transmission shaft 202 to achieve smooth rotation. An electric telescopic rod 213 is fixedly installed on the car body 100. The end of the electric telescopic rod 213 is fixedly connected to a transmission frame 212. The transmission frame 212 is fixedly installed with a bearing 211 which is rotatably connected to the transmission shaft 202. The electric telescopic rod 213 is started to extend and retract its free end. The transmission frame 212 moves with the electric telescopic rod 213. The transmission frame 212 can drive the transmission shaft 202 to move. The scraper 205 moves with the transmission sleeve 204 on the transmission shaft 202, and then can drive the scraper 205 to move, so as to clean the slag at different positions in the ladle.

[0036] Furthermore, limit blocks 210 are fixedly connected on both sides of the transmission shaft 202. The limit blocks 210 are slidably connected to the inner wall of the sleeve 209 through a slide groove. The setting of the limit blocks 210 allows the transmission shaft 202 to move while rotating, and is used to monitor the pressure of the gears on the transmission shaft 202, and convert the pressure into a control signal of the hydraulic telescopic rod 208, thereby adjusting the length of the hydraulic telescopic rod 208, controlling the angle of the scraper 205, and adapting to the inner diameter of the ladle.

[0037] A gear pressure controller 214 for monitoring the working pressure of the scraper 205 is installed on the sleeve 209 .

[0038] According to the embodiment, the motor 201 starts to drive the transmission shaft 202 to rotate thirty degrees, and the scraper 205 moves with the transmission shaft 202. Then the motor 201 drives the transmission shaft 202 to rotate sixty degrees, and the scraper 205 continues to move with the transmission shaft 202. Through the rotation of the motor 201 drive device, the scraper 205 can quickly and accurately clean the same position multiple times, reducing the time of manual cleaning and improving work efficiency.

[0039] Embodiment 2:

[0040] The mismatch between the scraper 205 and the inner wall of the ladle may cause uneven friction of the scraper during the cleaning process. Such uneven contact will accelerate the wear of the scraper 205 and increase the maintenance and replacement costs. In order to solve the above problems, combined with Figure 3 As shown, on the basis of embodiment one, the adjustment component 206 includes a spring 2064 fixedly connected to the transmission sleeve 204, a transmission rod 2061 is fixedly connected to the spring 2064, a connecting plate 2062 is fixedly connected to the end of the transmission rod 2061, and push blocks 2063 are hinged between the scraper 205 on both sides of the connecting plate 2062. The spring 2064 pushes the transmission rod 2061 to move, so that the scraper 205 on the connecting plate 2062 contacts the inner wall of the ladle, and then can adapt to ladles of different sizes, ensuring that no matter how the size of the ladle changes, the cleaning effect can remain consistent.

[0041] Specifically, a frame 2066 is fixedly connected to the transmission sleeve 204, an electromagnetic block 2065 is fixedly connected to the transmission rod 2061, a magnetic plate 2067 for fixing the scraper 205 is installed in the frame 2066, the electromagnetic block 2065 is slidably connected to the magnetic plate 2067, when the scraper 205 contacts the inner wall of the ladle, the magnetic plate 2067 is activated to fix the electromagnetic block 2065, and then the scraper 205 on the transmission rod 2061 can be fixed to avoid displacement of the scraper 205 during cleaning, which is beneficial to improve the cleaning quality, ensure that the scraper 205 maintains a fixed position during the entire cleaning process, reduce uneven cleaning caused by vibration or other external factors, and improve the stability of the entire cleaning operation.

[0042] According to the embodiments, the continuous scraping action can more effectively remove the slag on the inner wall of the ladle, ensure the thoroughness of the cleaning, and thus improve the quality of the production process.

[0043] Embodiment three:

[0044] After cleaning the ladle, a large amount of slag will remain in the ladle. In order to take out the slag in the ladle, Figure 1 , Figure 5 and Figure 6 As shown, on the basis of the first embodiment, the vehicle body 100 is provided with a movable shell 301, a belt conveyor 302 is installed in the shell 301, and a scraper 305 for exporting the slag in the ladle is provided on the conveyor. The shell 301 is sent into the ladle, and then the belt conveyor 302 is started to make the scraper 305 operate to bring out the slag in the ladle.

[0045] Specifically, a plurality of sliding sleeves 303 are fixedly connected to the belt conveyor 302, a plurality of springs 304 are fixedly connected inside the sliding sleeves 303, the scraper 305 is slidably connected to the sliding sleeves 303 and fixedly connected to the springs 304, and the setting of the springs 304 can contact slag at different depths and bring the slag out.

[0046] Furthermore, a second motor 306 is fixedly installed on the car body 100, a screw 307 is fixedly connected to the output end of the second motor 306, a load-bearing block 308 is threadedly connected to the screw 307 and is slidably connected to the inner wall of the car body 100, and the outer shell 301 is fixedly connected to the load-bearing block 308. When the second motor 306 is started, the screw 307 is driven to rotate, and the screw 307 rotates to send the outer shell 301 into the ladle through the load-bearing block 308.

[0047] It can be known from the above embodiments that: first, the vehicle body 100 is moved in front of the ladle, and then the electric telescopic rod 213 is started to extend and retract its free end, and the transmission frame 212 moves with the electric telescopic rod 213, and the transmission frame 212 can drive the transmission shaft 202 to move, and the scraper 205 moves with the transmission sleeve 204 on the transmission shaft 202, and the scraper 205 is moved into the ladle, and the motor 201 is started to drive the transmission shaft 202 to rotate thirty degrees, and the scraper 205 moves with the transmission shaft 202, and then the motor 201 drives the transmission shaft 202 to rotate sixty degrees, and the scraper 205 continues to move with the transmission shaft 202, and then the same position of the inner wall of the ladle can be continuously cleaned.

[0048] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0049] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
