Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1- Figure 5 This utility model provides an embodiment of a furnace repair device that allows the furnace to operate without interruption. The device includes a base 1, a mixing tank 21, and a stirring assembly. A caster wheel 4 is fixedly connected to the bottom of the base 1. A push-pull rod 5 is fixedly connected to the right end of the base 1. The stirring assembly is located on the top of the base 1. The mixing tank 21 is located on the top of the base 1. A feed valve 22 is fixedly connected to the top of the mixing tank 21. A pump body 23 is fixedly connected to the top of the base 1. A first connecting hose 24 is fixedly connected between the pump body 23 and the mixing tank 21. A limiting frame 226 is fixedly connected to the top of the base 1. A movable frame 29 is slidably connected to the outside of the limiting frame 226. A first semicircular block 25 is fixedly connected to the rear end of the movable frame 29. A support plate 27 is fixedly connected to the left end of the movable frame 29. A short shaft 222 is rotatably connected inside the support plate 27. A fourth semicircular block 223 is fixedly connected to the rear end of the short shaft 222. A rigid pipe 224 is fixedly connected inside the pump body 23. A second connecting hose 26 is fixedly connected between the rigid pipe 224 and the pump body 23. The second connecting hose 26 is located inside the first semicircular block 25. A nozzle 225 is fixedly connected to the left end of the rigid pipe 224. The support plate 27 is moved up and down by the moving frame 29. The short shaft 222 rotates inside the support plate 27, which drives the nozzle 225 to adjust its angle, thereby meeting the needs of the staff. This allows the staff to repair the furnace without having to approach it, enabling repairs to be performed without stopping the furnace, improving the accuracy of furnace repairs, eliminating the need to stop the furnace and wait for it to cool down, increasing production efficiency, and reducing production costs. The stirring component stirs the repair mixture inside the mixing tank 21, improving the mixing efficiency of the repair mixture, thus improving the repair effect on the furnace and enhancing the practicality of the device.
[0024] Please see Figure 1 - Figure 4In this embodiment, a first toothed plate 28 is fixedly connected to the front end of the limiting frame 226. A fixing block 210 is fixedly connected inside the moving frame 29. A worm gear 211 is rotatably connected inside the fixing block 210 and is rotatably connected inside the moving frame 29. A rotating disk 212 is fixedly connected to the outside of the worm gear 211. A worm wheel 213 meshes with the outside of the worm gear 211. An optical shaft 214 is fixedly connected inside the worm wheel 213 and is rotatably connected inside the moving frame 29. A first gear 215 is fixedly connected to the outside of the optical shaft 214 and meshes with the outside of the first toothed plate 28. A second toothed plate 28 is fixedly connected to the front end of the support plate 27. The second semicircular block 216 has a rotating shaft 217 internally connected to it. A threaded rod 218 is fixedly connected to the left end of the rotating shaft 217. A third semicircular block 219 is fixedly connected to the front end of the support plate 27. The threaded rod 218 is threaded into the interior of the third semicircular block 219. A second toothed plate 220 is slidably connected inside the support plate 27. The threaded rod 218 is rotatably connected inside the second toothed plate 220. A second gear 221 is fixedly connected to the outside of the short shaft 222, meshing with the outside of the second toothed plate 220. The moving frame 29 drives the support plate 27 to move up and down, while the short shaft 222 rotates within the support plate 27. This allows the nozzle 225 to be angled, meeting the needs of operators and eliminating the need for personnel to approach the calcining furnace for repairs. Repairs can be performed without stopping the furnace, improving accuracy and eliminating the need to stop the furnace to cool down, thus increasing production efficiency, reducing costs, and enhancing the device's practicality. The moving frame 29 has a corresponding groove on the limiting frame 226, allowing it to slide outside the limiting frame 226 and limit the support plate 27, enabling height adjustment. A limiting plate is fixedly connected to the top of the limiting frame 226. The top of the support plate 27 limits the height of the support plate 27, preventing the moving frame 29 from falling off the limiting frame 226 and improving its practicality. The moving frame 29 has a matching groove at the corresponding position of the first toothed plate 28. The first toothed plate 28 is set in the groove of the moving frame 29, so that it is not affected by the first toothed plate 28 when the limiting frame 226 moves up and down, improving the practicality of the device. The support plate 27 has a matching groove at the corresponding position of the second toothed plate 220. The second toothed plate 220 slides in the groove of the support plate 27, limiting the second toothed plate 220 and driving the nozzle 225 to adjust the angle, improving practicality.
[0025] Please see Figure 5In this embodiment, the stirring assembly includes a mounting frame 31, which is fixedly connected to the outside of the mixing tank 21 and is located on the top of the base 1. An internal hexagon bolt 32 is installed inside the mounting frame 31 and threadedly connected to the inside of the base 1. A motor 33 is fixedly connected to the top of the mixing tank 21, and a long shaft 34 is fixedly connected to the output end of the motor 33. The long shaft 34 is rotatably connected to the inside of the mixing tank 21. A fixing sleeve 35 is fixedly connected to the outside of the long shaft 34, and stirring blades 36 are fixedly connected to the outside of the fixing sleeve 35. The stirring assembly improves the mixing efficiency of the repair mixture inside the mixing tank 21 by stirring it, thereby improving the repair effect on the calcining furnace and enhancing the practicality of the device. Three sets of stirring blades 36 are arranged sequentially inside the mixing tank 21, thereby improving the mixing efficiency of the repair mixture inside the mixing tank 21.
[0026] During operation, the push-pull rod 5 moves the entire assembly to the desired location. Then, repair material is added to the mixing tank 21 via the feed valve 22. At this point, the motor 33 is started, driving the long shaft 34 to rotate inside the worm gear 211. This rotates the three sets of stirring blades 36 via the fixed sleeve 35, ensuring thorough mixing of the repair material in the mixing tank 21. Next, the pump body 23 is started, discharging the repair material from the mixing tank 21 through the first connecting hose 24. The repair mixture is then sprayed from the nozzle 225 through the second connecting hose 26 and the rigid pipe 224, evenly applying the repair material to the area requiring repair. Simultaneously, rotating the rotating disc 212 drives the worm gear... The rod 211 rotates, and through the meshing of the worm gear 213 and the worm 211, it drives the optical shaft 214 to rotate inside the moving frame 29, which in turn drives the first gear 215 to mesh with the first toothed plate 28, causing the support plate 27 to move up and down. By rotating the rotating shaft 217, it drives the threaded rod 218 to be threadedly connected inside the third semicircular block 219, which in turn drives the second toothed plate 220 to reciprocate inside the support plate 27. Through the meshing of the second gear 221 and the second toothed plate 220, it drives the short shaft 222 to rotate inside the support plate 27, which in turn drives the nozzle 225 to adjust its angle, thereby meeting the user's needs and allowing for repairs to be performed when the calcining furnace is not shut down.
[0027] Through the above steps, the moving frame 29 drives the support plate 27 to move up and down, and the short shaft 222 rotates inside the support plate 27, which drives the nozzle 225 to adjust the angle, thereby meeting the needs of the staff. This eliminates the need for staff to approach the calcining furnace for repairs, allowing repairs to be performed without stopping the calcining furnace, improving the accuracy of furnace repairs, and eliminating the need to stop the furnace and wait for it to cool down, thus solving the problem of complete production line interruption and a significant drop in production efficiency.
