[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention. Example 1

[0020] Please refer to Figure 1 - Figure 7 A smelting ash dissolving device, comprising: The box 1 has vertically arranged stirring rods 2 inside. The top of the box 1 is fixedly connected to a drive mechanism 3 to provide power to the device. The top of the inner side of the box 1 is provided with a planetary transmission assembly 4. There are multiple stirring rods 2 arranged in a ring array. All stirring rods 2 are connected to the planetary transmission assembly 4, and the stirring rods 2 are driven through the planetary transmission assembly 4. The cleaning component 5 is located inside the housing 1 and below the planetary transmission component 4. The cleaning component 5 can rotate with the multiple stirring rods 2 and can also slide along the length of the stirring rods 2. The cleaning component 5 is used to clean the inner wall of the housing 1 and the outer side of the stirring rods 2. The cleaning component 5 can clean the smelting ash adhering to the inner wall of the housing 1 and the stirring rods 2 so as to achieve the purpose of fully stirring and dissolving the smelting ash. The bottom bracket 6 is located at the bottom inside the box 1 and is rotatably connected to the box 1. The lower ends of the multiple stirring rods 2 are rotatably connected to the bottom bracket 6.

[0021] Specifically, the housing 1 includes a main body 27 and a cover 28. The cover 28 is detachably fixed to the top of the main body 27. An inlet 29 is provided at the upper end of the cover 28 for feeding smelting ash and dissolving liquid into the housing 1. A discharge port 30 is provided on the lower periphery of the main body 27 for discharging the smelting ash and dissolving liquid. The planetary transmission assembly 4 is located inside the cover 28. An exhaust port 31 is also provided at the upper end of the cover 28 for discharging the gas generated during the smelting ash dissolving process. Furthermore, an activated carbon filter is provided on the exhaust port 31. By using the activated carbon filter, the gas generated during the smelting ash dissolving process can be filtered and purified before being discharged.

[0022] Specifically, the cleaning assembly 5 includes a cleaning frame assembly 12. A flexible scraper ring 13 is fitted on the outer side of the cleaning frame assembly 12. The outer side of the flexible scraper ring 13 fits against the inner wall of the box body 27, which can effectively scrape off the smelting ash adhering to the inner wall of the box body 1. A flexible scraper sleeve 14 is provided on the cleaning frame assembly 12 at a position corresponding to each stirring rod 2. The flexible scraper sleeve 14 is fitted on the outer side of the corresponding stirring rod 2 and is used to clean the smelting ash adhering to the outer side of the stirring rod 2. A fixing screw 15 is provided in the middle of the cleaning frame assembly 12. The lower end of the fixing screw 15 is fixedly connected to the bottom of the box body 27, and the upper end of the fixing screw 15 is rotatably connected to the planetary transmission assembly 4. A connecting screw sleeve 16 is rotatably connected in the middle of the cleaning frame assembly 12. The connecting screw sleeve 16 is threadedly connected to the fixing screw 15. A limit component is also provided on the inner side of the cleaning frame assembly 12. The limit component is used to limit the connection between the cleaning frame assembly 12 and the connecting screw sleeve 16.

[0023] It can be seen that when the limiting component realizes the limiting connection between the cleaning frame 12 and the connecting screw sleeve 16, the cleaning component 5 slides along the length direction of the stirring rod 2 through the threaded connection between the connecting screw sleeve 16 and the fixing screw 15, thereby cleaning the smelting ash adhering to the inner wall of the box 1 through the flexible scraper ring 13, and cleaning the smelting ash adhering to the outer side of the stirring rod 2 through the flexible scraper sleeve 14.

[0024] Furthermore, the cleaning frame assembly 12 includes an inner frame 17, an outer frame 18 is provided on the outside of the inner frame 17, a flexible scraper ring 13 is sleeved on the outside of the outer frame 18, the inner frame 17 and the outer frame 18 are fixedly connected by a connecting arm 19, a connecting frame 23 is fixedly connected to the inside of the inner frame 17, a connecting screw sleeve 16 is located in the middle of the connecting frame 23, the connecting frame 23 has a double-layer structure, and the limiting component is located on the inside of the connecting frame 23.

[0025] The lower end of the cleaning frame assembly 12 is also provided with a scraper 24. The scraper 24 is arc-shaped. One end of the scraper 24 is fixedly connected to the inner frame 17, and the other end of the scraper 24 is fixedly connected to the outer frame 18. After the cleaning frame assembly 12 moves to the bottom of the inner side of the box 1, the limiting component disconnects the connection between the cleaning frame assembly 12 and the connecting screw sleeve 16, so that the scraper 24 can scrape and clean the smelting ash adhering to the bottom of the box 1. Example 2

[0026] The smelting ash dissolving device provided in Example 1 is further optimized, specifically, as follows: Figure 3 As shown, the planetary transmission assembly 4 includes a fixed ring 7, which is fixedly connected to the inner wall of the box cover 28. An internal gear ring 8 is fixedly connected to the inner side of the fixed ring 7. A stabilizer 9 is provided on the inner side of the internal gear ring 8. A sun gear 10 is rotatably connected to the middle of the stabilizer 9. A planet gear 11 is rotatably connected to the end of the stabilizer 9 at a position corresponding to each stirring rod 2. The sun gear 10 and the planet gear 11 are meshed and connected. The planet gear 11 is meshed and connected to the internal gear ring 8. The output end of the drive mechanism 3 passes through the stabilizer 9 and is connected to the sun gear 10.

[0027] Through the above structural design, the drive mechanism 3 drives the sun gear 10 to rotate, and the sun gear 10 drives the planet gear 11 to rotate through meshing transmission. The planet gear 11 revolves around the sun gear 10 while rotating on its own axis, thereby realizing the synchronous rotation of multiple stirring rods 2 and improving stirring efficiency. Example 3

[0028] The smelting ash dissolving device provided in Example 1 is further optimized, specifically, as follows: Figure 5 As shown, the flexible scraper sleeve 14 includes a cleaning sleeve 21. Mounting seats 20 are provided at the upper and lower ends of the inner frame 17 and at positions corresponding to the stirring rod 2. The end of the cleaning sleeve 21 is sleeved on the outside of the mounting seat 20. The cleaning sleeve 21 and the mounting seat 20 are fixedly connected by a snap ring 22.

[0029] Through the above structural design, the cleaning sleeve 21 can be connected to the inner frame 17 through the mounting base 20, and the connection limit between the cleaning sleeve 21 and the mounting base 20 can be realized through the snap ring 22. When the cleaning frame assembly 12 moves along the length of the stirring rod 2, the smelting ash adhering to the surface of the stirring rod 2 can be cleaned through the cleaning sleeve 21. Example 4

[0030] The smelting ash dissolving device provided in Example 1 is further optimized, specifically, as follows: Figure 6 As shown, the limiting component includes a telescopic mechanism 25, and a connecting slot 26 is provided on the side of the connecting screw sleeve 16. When the telescopic end of the telescopic mechanism 25 extends, it can be inserted into the connecting slot 26 to realize the connection limiting between the cleaning frame 12 and the connecting screw sleeve 16.

[0031] Through the above structural design, when the cleaning component 5 does not need to be raised or lowered, the telescopic end of the telescopic mechanism 25 is in a retracted state, so that the cleaning frame 12 is not connected to the connecting screw sleeve 16; when it is necessary to adjust the height position of the cleaning component 5, the telescopic end of the telescopic mechanism 25 extends into the connecting slot 26 to realize the connection between the cleaning frame 12 and the connecting screw sleeve 16. Then, through the threaded connection between the connecting screw sleeve 16 and the fixing screw 15, when the stirring rod 2 drives the cleaning frame 12 to rotate, the position adjustment of the cleaning frame 12 can be synchronously driven by the cooperation of the connecting screw sleeve 16 and the fixing screw 15.
