[0002] A converter mobile fume hood is a device used in the steel production process to collect and discharge high-temperature waste gases containing harmful gases. During the converter steelmaking process, a large amount of waste gas is generated, including high-temperature gases, dust, and harmful gases. The main function of the mobile fume hood is to effectively collect these waste gases and guide them to the waste gas treatment system. This not only helps to keep the air in the furnace area clean, but also avoids the direct emission of waste gases, reducing environmental pollution. Furthermore, by collecting waste gases and introducing them into a dedicated exhaust system, the mobile fume hood can effectively reduce the concentration and temperature of waste gases in the furnace area, thereby providing operators with a safer and healthier working environment.

[0003] During the steelmaking process, converters generate a large amount of waste gas. The function of the fume hood is to guide this waste gas to the waste gas treatment system. The lifting and guiding device can adjust the position of the fume hood in real time. The automation function of the lifting and guiding device reduces the need for manual intervention, lowers the difficulty of operation and safety risks. However, when the lifting and guiding device lifts the fume hood during converter maintenance or cleaning, the fume hood occupies the space above the converter, increasing the limitation of maintenance work space and making it difficult to set up maintenance equipment. During maintenance work around the furnace, it can easily affect the operating space and work efficiency of maintenance personnel. Therefore, we propose a converter movable fume hood lifting and guiding device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6This utility model provides a technical solution: a converter movable fume hood lifting and guiding device, including a movable fume hood body 1 and a connecting pipe 2. Connecting pipes 2 are fixed to both sides of the movable fume hood body 1. The end of the connecting pipe 2 away from the movable fume hood body 1 is connected to an internally threaded pipe 201. The connecting pipe 2 is slidably connected to a slider 202. The internally threaded pipe 201 is connected to a screw 203, and the lower end of the screw 203 is movably connected to the slider 202 via a bearing. The upper end of the screw 203 is connected to a mounting plate 20 via a bearing. 4. A movable connection is provided. A synchronization assembly 205 is provided on the inner side of the mounting plate 204. The synchronization assembly 205 includes three synchronous pulleys and a synchronous belt. The synchronous pulleys of the synchronization assembly 205 are movably connected to the mounting plate 204 via bearings. The synchronous pulleys at both ends of the synchronization assembly 205 are fixed to the screw 203, and the synchronous pulley in the middle of the synchronization assembly 205 is connected to the output end of the drive motor 206. The drive motor 206 is connected to the mounting plate 204, and a platform support plate 207 is provided on the outer side of the mounting plate 204. One end of the mounting plate 204 is movably connected to the gear disc 208 via a bearing seat, and gear discs 209 are fixed on both sides of the gear disc 208. The outer side of the gear disc 209 is movably connected to the slider 210 via a bearing. A groove 211 is provided on the side of the support plate 207 near the slider 210, and the slider 210 slides into the groove 211. The upper end of the gear disc 208 is opposite to the upper end of the gear plate 212, and the lower end of the gear plate 212 is fixed to the internal threaded tube 201. The gear disc 209 is connected to the gear plate 213. The toothed plate 213 is fixed to the support plate 207. The inner spacing of the connecting pipe 2 matches the diameter of the slider 202. The internal threaded pipe 201 is threadedly connected to the screw 203. The diameter of the slider 202 is larger than the inner spacing of the internal threaded pipe 201. The synchronous pulley and synchronous belt of the synchronous assembly 205 are meshed. The toothed disc 208 is meshed with the toothed plate 212. The toothed disc 209 is meshed with the toothed plate 213. The cross-sectional dimensions of the slider 210 match the cross-sectional dimensions of the groove 211.

[0025] In specific implementation, according to Figures 1-6Install the support plate 207 together with the workshop, start the drive motor 206, and make the output end of the drive motor 206 drive the synchronous pulley in the middle of the synchronous assembly 205 to rotate. Through the engagement of the synchronous pulley and the synchronous belt of the synchronous assembly 205, the output end of the drive motor 206 can drive the screw 203 to rotate through the synchronous assembly 205. The internal threaded tube 201 is threadedly connected to the screw 203, so that the internal threaded tube 201 slides along the screw 203, thereby causing the internal threaded tube 201 to drive the movable smoke through the connecting pipe 2. The hood body 1 moves up or down. When the connecting pipe 2 drives the movable hood body 1 to move down, the inner spacing of the connecting pipe 2 matches the diameter of the slider 202. The diameter of the slider 202 is larger than the inner spacing of the internal threaded pipe 201, and the connecting pipe 2 and the slider 202 slide together to prevent them from disengaging. This allows the connecting pipe 2 to stably drive the movable hood body 1 to move down and extract the large amount of waste gas generated by the converter. When the converter needs maintenance, the connecting pipe 2 drives the movable hood body 1 to move up. Furthermore, when the connecting pipe 2 moves upward, it can drive the toothed plate 212 to move upward through the internal threaded pipe 201. The toothed disc 208 engages with the toothed plate 212, allowing the toothed plate 212 to push the toothed disc 208 to rotate. This causes the toothed disc 208 to drive the toothed disc 209 to rotate. The toothed disc 209 then engages with the toothed plate 213, allowing the toothed disc 209 to rotate along the toothed plate 213. This allows the toothed disc 209 to push the mounting plate 204 to move along the inner side of the support plate 207. At this time, the toothed disc 209... The slider 210 can slide along the slide groove 211. By matching the cross-sectional dimensions of the slider 210 with those of the slide groove 211, the slider 210 can slide stably along the slide groove 211, thereby allowing the mounting plate 204 to move stably along the inner side of the support plate 207. This allows the movable fume hood body 1 to move upwards while simultaneously moving to the side, thus moving the movable fume hood body 1 away from the top of the converter. This makes the space above the converter easier to install maintenance equipment and less likely to affect the operating space and work efficiency of maintenance personnel.

[0026] In summary, starting the drive motor 206 causes the internal threaded pipe 201 to move the movable fume hood body 1 up or down via the connecting pipe 2. When the connecting pipe 2 moves the movable fume hood body 1 down, the connecting pipe 2 and the slider 202 slide together, preventing the connecting pipe 2 from disengaging from the slider 202. This allows the connecting pipe 2 to stably move the movable fume hood body 1 down to extract a large amount of waste gas generated by the converter. When the converter needs maintenance, the connecting pipe 2 moves the movable fume hood body 1 up, and when the connecting pipe 2 moves up, it also moves the toothed plate 212 up, causing the movable fume hood body 1 to move to the side while moving up. This makes it easier to install maintenance equipment in the space above the converter, and it does not easily affect the operating space and work efficiency of maintenance personnel. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
