[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 3The utility model provides an embodiment: an oxygen-enriched blowing furnace, including a furnace body 1, a stirring mechanism 2 is arranged in the furnace body 1, a servo motor 2 6 is fixedly connected to the lower part of one side of the furnace body 1, the output end of the servo motor 2 6 passes through the inner wall of the furnace body 1 and is fixedly connected to a gear 3 16, a gear ring 7 is meshed on the upper side of the gear 3 16, a connecting plate 8 is fixedly connected to the inner wall of the gear ring 7, a toothed plate 9 is fixedly connected to the middle part of the inner wall of the furnace body 1, the toothed plate 9 passes through the connecting plate 8, and the inner side of the toothed plate 9 is meshed with a toothed ring 7. There are multiple gears 10, one end of each of the multiple gears 10 is connected to a connecting pipe 11, one end of each of the multiple connecting pipes 11 penetrates the side wall of the connecting plate 8 and is fixedly connected to a nozzle 12; the inner wall of the connecting plate 8 is provided with multiple limiting grooves 14, and the limiting rings 13 are rotatably connected in the multiple limiting grooves 14, and one end of each of the limiting rings 13 is fixedly connected to the gear 10; an air intake pipe 5 is fixedly connected to the middle of one side of the furnace body 1, and one end of the air intake pipe 5 penetrates the inner wall of the furnace body 1 and is connected to the gear plate 9;

[0030] Specifically, oxygen-enriched air can be blown into the connecting disk 8 through the air inlet pipe 5 and enter the connecting pipe 11 through the gear 2 10, so that it can be sprayed into the furnace body 1 through the nozzle 12. At this time, by starting the servo motor 2 6, the connected gear 3 16 can be driven to rotate and the meshing gear ring 7 can continue to rotate. The fixed connecting disk 8 can be driven to rotate through the gear ring 7. Since the gear 2 10 is engaged in the limiting groove 14 through the limiting ring 13, the limiting groove 14 can limit the gear 2 10, so that the connecting disk 8 can It can drive gear 2 10 to revolve along with the connecting disk 8. Since gear 2 10 rotates along with the connecting disk 8 and meshes with the toothed disk 9, and the toothed disk 9 is connected to the side wall of the furnace body 1 and therefore does not rotate along with the connecting disk 8, under the action of the toothed disk 9, gear 2 10 can rotate while revolving. When gear 2 10 rotates, it can drive the connected connecting pipe 11 to rotate, and through the connecting pipe 11, it can drive the nozzle 12 to rotate, thereby ensuring that oxygen-enriched air can be evenly blown into the furnace body 1.

[0031] Reference Figure 1-Figure 3 , the stirring mechanism 2 includes a gear 207, a plurality of gears 207 are rotatably connected to the front wall of the furnace body 1, the rear ends of the plurality of gears 207 penetrate the inner front wall of the furnace body 1 and are fixedly connected with a spiral shaft 208, a bracket 201 is fixedly connected to one side of the front wall of the furnace body 1, a servo motor 204 is fixedly connected to the front wall of the bracket 201, an output end of the servo motor 204 penetrates the bracket 201 and is fixedly connected with a connecting rod 202, the top of the connecting rod 202 is rotatably connected with a connecting rod 203, the bottom end of the connecting rod 203 is rotatably connected with a rack 205, and the rack 205 is meshed with a gear 207 on one side; the outer peripheries of the upper and lower ends of the rack 205 are slidably connected with a limit block 206, and the two limit blocks 206 are fixedly connected to the front wall of the furnace body 1; the rear ends of the plurality of spiral shafts 208 are rotatably connected to the inner rear wall of the furnace body 1, and the rotation directions of adjacent spiral shafts 208 are opposite;

[0032] Specifically, by starting the servo motor 1 204, the connecting rod 1 202 can be driven to rotate. When the connecting rod 1 202 rotates, the connected connecting rod 203 can be driven to move. Since the connecting rod 203 is connected to the rack 205 and the rack 205 is limited by the limit block 206, as the connecting rod 1 202 rotates, the connecting rod 203 can be driven to rotate and pull the rack 205 to reciprocate up and down. When the rack 205 moves up and down, it can drive the meshing gear 1 207 to rotate back and forth. Since multiple gears 1 207 are meshed with each other, when one gear 1 207 rotates, it can drive multiple gears 1 207 to rotate at the same time. When multiple gears 1 207 rotate, they can drive the connected screw shaft 208 to rotate, so that the material in the furnace body 1 can be stirred. Since the rotation directions of adjacent screw shafts 208 are opposite, they can simultaneously stir the material in the furnace body 1 to move back and forth, so that the material can be fully mixed and evenly mixed.

[0034] Specifically, the feed pipe 4 can facilitate the staff to put materials into the furnace body 1. After the materials are processed in the furnace body 1, they can be discharged through the discharge pipe 15. An exhaust fan 3 is provided to discharge the smoke generated by the materials in the furnace body 1.

[0035] Working principle: In actual use, by starting the servo motor 26, the connected gear 3 16 can be driven to rotate and the meshing gear ring 7 and the connecting disk 8 can be driven to rotate. Through the connecting disk 8, the gear 2 10 can be driven to revolve along with the connecting disk 8, and the gear 2 10 can be driven to rotate by itself through the toothed disk 9, thereby driving multiple connecting pipes 11 and nozzles 12 to rotate while revolving along with the connecting disk 8, thereby ensuring that oxygen-enriched air can be evenly blown into the furnace body 1; in addition, by starting the servo motor 1 204, the connecting rod 1 202 can be driven to rotate and the rack 205 can be driven to retract and retract through the connecting rod 203. When the rack 205 retracts and retracts, it can drive the gear 1 207 to rotate forward and reverse, thereby driving multiple gears 1 207 to rotate forward and reverse at the same time. When the gear 1 207 rotates, it can drive the connected spiral shaft 208 to rotate, thereby stirring the material in the furnace body 1 to ensure that it is evenly mixed.
