Description

Technical Field

[0001] The utility model relates to the technical field of melting furnaces, in particular to a green, high-efficiency, energy-saving, low-carbon regenerated lead full-oxygen vertical blowing melting furnace. Background Art

[0002] Lead full oxygen vertical blowing is an efficient smelting technology, which is usually used in the field of lead smelting. In this process, oxygen (O2) is injected into the furnace through the blowing system, and reacts with the lead raw material to form lead oxide (PbO). This reaction is usually carried out at high temperature to ensure full oxidation of the lead. Lead full oxygen vertical blowing technology has important application prospects in lead smelting, which can improve production efficiency, reduce energy consumption and reduce environmental pollution. This smelting technology is usually completed in a smelting furnace.

[0003] In a traditional secondary lead all-oxygen vertical blowing smelting furnace, the furnace body is the outer shell of the entire smelting system, usually made of high-temperature refractory materials to withstand high temperatures and chemical corrosion. The furnace is the melting area inside the furnace body, which is used to accommodate smelting raw materials and produce molten metal. The raw material supply system is used to transport waste lead batteries and other waste lead materials into the furnace for melting and processing. The system usually includes equipment such as conveyor belts, feeders or hoppers. The waste heat recovery device is used to recover the waste heat energy generated by the furnace. The waste heat is usually converted into steam or hot water through a heat exchanger, which is used to preheat fresh feed or provide the heat energy required in the production process.

[0004] However, the gas supply system used in the traditional secondary lead full oxygen vertical blowing smelting furnace often only adopts an integrated gas supply structure, usually including components such as a gas supply pipe, a blower, and a nozzle. The gas ejection method of this gas supply method is relatively simple, and it is impossible to evenly inject oxygen or air into the furnace to maintain the combustion and melting process, thereby reducing the efficiency of the secondary lead full oxygen vertical blowing. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a green, efficient, energy-saving and low-carbon recycled lead all-oxygen vertical blowing smelting furnace, which aims to improve the gas supply method used in the traditional recycled lead all-oxygen vertical blowing smelting furnace, the gas ejection method of which is relatively single, and oxygen or air cannot be evenly injected into the furnace to maintain the combustion and melting process, thereby reducing the efficiency of the recycled lead all-oxygen vertical blowing.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a green, efficient, energy-saving, low-carbon, recycled lead, full-oxygen vertical blowing smelting furnace, comprising a melting furnace, a gas supply pipe is fixedly connected to the top of the melting furnace, a motor is fixedly connected to the inside of the gas supply pipe, a worm is fixedly connected to the output end of the motor, a plurality of turntables are fixedly connected to the inside of the gas supply pipe, both ends of the worm are rotatably connected to the inside of the turntable, a turbine is rotatably connected to the inside of the gas supply pipe, an eccentric wheel is fixedly connected to the side wall of the turbine, a connecting rod is rotatably connected to the side wall of the eccentric wheel, a connecting frame is rotatably connected to the inside of the gas supply pipe, one end of the connecting rod is rotatably connected to the side wall of the connecting frame, one end of the worm is fixedly connected to the gas supply nozzle, the side wall of the connecting frame is rotatably connected to the side wall of the gas supply nozzle, and a drainage assembly is provided on the side wall of the melting furnace.

[0007] Furthermore, the drainage assembly includes a drainage pipe, and the drainage pipe is fixedly connected to the side wall of the melting furnace.

[0008] Furthermore, a recovery pipe is fixedly connected to the side wall of the melting furnace, and a connecting pipe is fixedly connected to the top of the recovery pipe.

[0009] Furthermore, a second motor is provided on the side wall of the connecting pipe, and a first gear is fixedly connected to the output end of the second motor.

[0010] Furthermore, a gear 2 is rotatably connected inside the connecting pipe, and the gear 1 is meshed with the gear 2.

[0011] Furthermore, two side walls of the gear are fixedly connected with connecting columns, and one end of the connecting column is fixedly connected with a screw rod.

[0012] Furthermore, the outer wall of the screw rod is threadedly connected to a slide, and the side wall of the slide is fixedly connected to a plug.

[0013] Furthermore, a plug head is fixedly connected to the outer wall of the plug column.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the worm is first driven to rotate by a motor, and the eccentric wheel is driven to rotate by a turbine so that the gas supply nozzle slides up and down while rotating. With this structure, the gas supply nozzle evenly injects oxygen or air into the furnace to maintain the combustion and melting process, and realizes the furnace atmosphere of full oxygen vertical blowing, thereby improving the full oxygen vertical blowing efficiency.

[0016] 2. In the utility model, the slide can slide on the outer wall of the screw by driving the gear one to rotate through the motor two. At this time, the plug can block the drainage pipe. This structure can realize the effective discharge of waste liquid, avoid secondary pollution, harm to the human body or the environment, and improve environmental protection.

[0022] 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.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a green, efficient, energy-saving, low-carbon, recycled lead, full-oxygen vertical blowing smelting furnace, comprising a melting furnace 1, a gas supply pipe 2 is fixedly connected to the top of the melting furnace 1, a motor 3 is fixedly connected inside the gas supply pipe 2, a worm 4 is fixedly connected to the output end of the motor 3, a plurality of turntables 5 are fixedly connected inside the gas supply pipe 2, both ends of the worm 4 are rotatably connected inside the turntable 5, a turbine 6 is rotatably connected inside the gas supply pipe 2, an eccentric wheel 7 is fixedly connected to the side wall of the turbine 6, a connecting rod 8 is rotatably connected to the side wall of the eccentric wheel 7, a connecting frame 9 is rotatably connected inside the gas supply pipe 2, one end of the connecting rod 8 is rotatably connected to the side wall of the connecting frame 9, a gas supply nozzle 10 is fixedly connected to one end of the worm 4, and a side wall of the connecting frame 9 is rotatably connected to the side wall of the gas supply nozzle 10, and a drainage component is provided on the side wall of the melting furnace 1.

[0024] Specifically, when the motor 3 is started, it transmits force to the worm 4, which causes the worm 4 to rotate in the turntable 5. At the same time, the worm 4 meshes with the turbine 6, pushing the turbine 6 to rotate in the gas supply pipe 2. The rotation of the turbine 6 causes the eccentric wheel 7 on the side wall to rotate. Due to the design of the eccentric wheel 7, the connecting rod 8 will move up and down, thereby pushing and pulling the connecting frame 9, causing the connecting frame 9 to rotate in the gas supply pipe 2 and change the inclination angle. This structure enables the connecting frame 9 to pull the gas supply nozzle 10, allowing the gas supply nozzle 10 to rotate inside the connecting frame 9 and repeatedly change the vertical height. This design ensures that oxygen or air can be evenly injected into the furnace, maintaining the atmosphere required for the combustion and melting process. By realizing the furnace atmosphere of full oxygen vertical blowing, this system significantly improves the efficiency of full oxygen vertical blowing, making the lead smelting process more stable and efficient.

[0025] Reference Figure 3 The discharge component includes a discharge pipe 11, which is fixedly connected to the side wall of the melting furnace 1. The side wall of the melting furnace 1 is fixedly connected with a recovery pipe 12. The top of the recovery pipe 12 is fixedly connected with a connecting pipe 13. The side wall of the connecting pipe 13 is provided with a motor 2 14. The output end of the motor 2 14 is fixedly connected with a gear 15. The connecting pipe 13 is internally rotatably connected with a gear 2 16. The gear 15 is meshed with the gear 2 16. The side wall of the gear 2 16 is fixedly connected with a connecting column 17. One end of the connecting column 17 is fixedly connected with a screw 18. The outer wall of the screw 18 is threadedly connected with a slide 19. The side wall of the slide 19 is fixedly connected with a plug column 20. The outer wall of the plug column 20 is fixedly connected with a plug head 21.

[0026] Specifically, when the motor 2 14 is started, it will output a rotational force and transmit this force to the gear 15 to make it start to rotate. The gear 15 meshes with the gear 2 16, causing the gear 2 16 to start to rotate inside the connecting pipe 13. This rotational action will also drive the connecting column 17 to rotate synchronously, thereby driving the screw 18 to start rotating. The rotation of the screw 18 is combined with the threaded connection relationship on the slide 19, causing the slide 19 to slide on its surface. As the position of the slide 19 changes, the plug 20 will also move accordingly. This displacement action will cause the plug 21 on the outer wall of the plug 20 to release the blockage of the drain pipe 11, so that the waste liquid inside the melting furnace 1 can flow out smoothly, and the drain can be effectively discharged through the recovery pipe 12 without causing secondary pollution, thereby protecting the human body and the environment from harm. The design of this drainage system not only realizes the effective treatment and discharge of waste liquid, but also takes environmental protection into consideration in the process, ensuring the minimum impact of the production process on the environment.

[0027] Working principle: when it is necessary to inject oxygen or air into the furnace, first start the motor 3. The motor 3 outputs a rotating force to the worm 4, which drives the worm 4 to rotate inside the turntable 5. While the worm 4 rotates, it drives the turbine 6 to rotate inside the air supply pipe 2 through the meshing relationship with the turbine 6. The rotation of the turbine 6 then drives the eccentric wheel 7 on its side wall to rotate. Due to the eccentric design of the eccentric wheel 7, the connecting rod 8 on the side wall of the eccentric wheel 7 moves up and down, and the connecting frame 9 is repeatedly pushed and pulled, so that the connecting frame 9 rotates inside the air supply pipe 2 and changes the inclination angle. At this time, the connecting frame 9 pulls the gas supply nozzle 10, so that the gas supply nozzle 10 repeatedly changes its vertical height while rotating inside the connecting frame 9. With this structure, the gas supply nozzle 10 evenly injects oxygen or air into the furnace to maintain the combustion and melting process, and realizes the furnace atmosphere of full oxygen vertical blowing, thereby improving the full oxygen vertical blowing efficiency. When it is necessary to discharge the waste liquid inside the melting furnace 1, start the motor 2 14, and the motor 2 14 outputs a rotating force to the gear 15 to drive the gear 15 to rotate. The gear 15 drives the gear 2 16 to rotate inside the connecting pipe 13 through the meshing relationship with the gear 2 16. The gear 2 16 rotates while driving the connecting column 17 on its side wall to rotate synchronously. The connecting column 17 can make the screw 18 rotate along with it. While the screw 18 rotates, the slide 19 slides on its surface through the threaded connection relationship with the slide 19. The change in the position of the slide 19 can drive the plug 20 on its side wall to move. At this time, the plug 21 on the outer wall of the plug 20 can release the blockage of the drain pipe 11 so that the waste liquid inside can flow out and be effectively discharged through the recovery pipe 12. This structure can realize the effective discharge of waste liquid, avoid secondary pollution, harm to the human body or the environment, and improve environmental protection.
