[0025] 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 implementation regulations described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6 The utility model provides a technical solution: a welded small slag pot, comprising a slag pot body 1, and a reinforcement ring 101 welded to the top surface of the slag pot body 1;

[0027] A heat recovery component 2 is provided inside the slag pot body 1, and a stirring mechanism 3 is provided above the reinforcement ring 101;

[0028] Among them, the heat recovery component 2 includes a spiral semicircular tube 201 fixed on the inner wall of the slag pot body 1, and the surface of the spiral semicircular tube 201 is provided with a supporting texture. The first extension tube 202 and the inclined tube 203 are symmetrically welded on both sides of the top of the slag pot body 1. The bottom end of the inclined tube 203 is welded to the lowest end of the spiral semicircular tube 201, and the inclined tube 203 is welded to the top of the spiral semicircular tube 201. The cross-section of the spiral semicircular tube 201 is semicircular; the spiral semicircular structure of the spiral semicircular tube 201 can increase the time for liquid water to pass through the slag pot body 1, providing time for heat conduction. At the same time, the supporting texture is a stripe along the direction of the spiral semicircular tube 201, which can increase the overall structural stability of the spiral semicircular tube 201 and avoid deformation of the spiral semicircular tube 201.

[0029] The outer ends of the first extension pipe 202 and the inclined pipe 203 are fixedly connected to a docking joint 204, and the docking joint 204 is plugged with a plug joint 206. The other end of the plug joint 206 is fixedly connected to an external water pipe 209. The two external water pipes 209 are respectively connected to an external water pump and an external water-using device; the external water pump pumps cold water into the spiral semicircular pipe 201, while accelerating the cooling of the bottom of the molten slag, and the external water-using device recycles and utilizes the heat energy in the hot water.

[0030] The outside of the butt joint 204 is fixedly connected to a limit ring 205, and the outside of the butt joint 204 and the plug joint 206 are both threadedly connected to the same threaded ring 207. The side of the threaded ring 207 is fixedly connected to a sealing sleeve 208, which fits the outside of the butt joint 204 and the plug joint 206; when the sealing sleeve 208 fits perfectly with the butt joint 204, the threaded track on its outside is connected. By docking the butt joint 204 and the plug joint 206, and then rotating the threaded ring 207 so that the threaded ring 207 moves from the plug joint 206 to the limit ring 205, the sealing sleeve 208 now covers the outside of the joint between the butt joint 204 and the plug joint 206. The sealing sleeve 208 is a rubber sleeve with a threaded track inside. The sealing sleeve 208 is also threadedly connected to the butt joint 204 and the plug joint 206. The elasticity of the rubber sleeve can prevent water from flowing out of the joint between the butt joint 204 and the plug joint 206.

[0031] The stirring mechanism 3 includes a plug-in frame 301, which is arranged in a cross shape. A docking port 302 is provided on the top surface of the reinforcement ring 101. The plug-in frame 301 is plugged into the docking port 302. A fixed cover 303 is fixedly connected to the middle of the plug-in frame 301, and suspension rings 310 are symmetrically fixed on both sides of the top surface of the plug-in frame 301. The multi-point plug-in of the plug-in frame 301 can increase the stability of the plug-in frame 301. At the same time, the plug-in and deadweight of the plug-in frame 301 can realize the rapid installation of the plug-in frame 301. The suspension ring 310 can facilitate the external crane and other equipment to lift the plug-in frame 301.

[0032] A rotating frame 304 is rotatably connected to the lower part of the fixed cover 303, and a connecting block 305 is rotatably connected to the middle part of the rotating frame 304. The bottom end of the connecting block 305 is fixedly connected to a stirring rod 306; a driving motor 307 is fixedly connected to the top surface of the fixed cover 303, and the output end of the driving motor 307 passes through the fixed cover 303 and is fixedly connected to a connecting inclined block 308. The bottom inclined surface of the connecting inclined block 308 is fixedly connected to a connecting shaft 309, and the connecting shaft 309 is rotatably connected to the middle part of the top surface of the connecting block 305; the connecting inclined block 308, the rotating frame 304, and the rotating connecting block 305 enable the stirring rod 306 to achieve stirring, thereby accelerating the cooling of the liquid slag.

[0033] Working principle: Before using this welded small slag pot, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6As shown, first, when high-temperature objects such as copper slag enter the equipment, the flowing water inside the spiral semicircular tube 201 will quickly heat up through heat conduction. As the external water pump draws out the hot water in the spiral semicircular tube 201, new cold water re-enters the spiral semicircular tube 201, which can promote the deep cooling of the liquid copper slag and increase the cooling rate of the high-temperature residue. In addition, the hot water can be transported to other equipment and used in water bath heating and other places where hot water is needed, thereby recovering the heat of the slag and avoiding heat waste.

[0034] By docking the butt joint 204 with the plug joint 206, and then rotating the threaded ring 207 so that the threaded ring 207 moves from the plug joint 206 to the limiting ring 205, the sealing sleeve 208 now covers the joint between the butt joint 204 and the plug joint 206, thereby realizing the detachable and quick disassembly of the water pipe. When the slag pot body 1 is transporting or dumping slag, the water pipe can be disassembled to prevent it from hindering the movement of the slag pot body 1.

[0035] After the molten slag is poured into the slag pot body 1, the splicing frame 301 is lifted up by a crane or other equipment and docked with the docking port 302, and then the driving motor 307 is started to rotate the connecting bevel 308, so that the connecting shaft 309 drives the connecting block 305 to swing, and under the rotation support of the rotating frame 304, the stirring rod 306 stirs the molten slag to cool it and improve the cooling efficiency. When the cooling is almost completed and the slag is more solidified, making it difficult for the stirring rod 306 to continue to stir quickly, the stirring rod 306 is lifted away to prevent the splicing frame 301 from affecting the transportation, dumping and addition of slag of the slag pot body 1.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
