[0035] Embodiment 1

[0036] As Figure 1-2As shown in the figure, this embodiment provides a high-efficiency sulfuric acid production device for the flue gas of battery smelting and recycling, including a bottom plate 1. First, place the bottom plate 1 in a suitable position. The left side of the top of the bottom plate 1 is fixedly connected with a smelting box 2, and the right side of the smelting box 2 is fixedly connected with an air outlet pipe 3. Then, dock the air outlet pipe 3 with a connecting pipe 10. A locking collar 4 is slidably connected to the outer part of the right side of the air outlet pipe 3. Then, slide the locking collar 4. A resisting plate 5 is fixedly connected to the right side of the air outlet pipe 3, so that the locking collar 4 contacts the movable beads 7 outside the resisting plate 5. A locking component is arranged outside the air outlet pipe 3. The adjusting component includes two sliding grooves 6. When the resisting plate 5 is placed inside the air outlet pipe 3, it will squeeze the movable beads 7 inside the resisting plate 5. The two sliding grooves 6 are opened on the upper and lower outer sides of the resisting plate 5. A movable bead 7 is rotatably connected to the inside of the sliding groove 6. At this time, the movable bead 7 will slide on the inner wall of the sliding groove 6.

[0037] A rubber ring 9 is slidably connected to the outside of the resisting plate 5. A first spring 8 is sleeved outside the air outlet pipe 3. One end of the first spring 8 is fixedly connected to the outside of the air outlet pipe 3, and the other end of the first spring 8 is fixedly connected to the inner side of the locking collar 4. At this time, the first spring 8 is compressed by force, and while being compressed, it will absorb the external force and generate a reaction force on the locking collar 4, making the locking collar 4 contact the movable bead 7 more tightly. A connecting pipe 10 is slidably connected to the right side of the resisting plate 5. The outside of the movable bead 7 contacts the outside of the connecting pipe 10 and also contacts the outside of the connecting pipe 10. The outside of the connecting pipe 10 contacts the inner wall of the locking collar 4. At this time, the locking collar 4 generates a pressure on the movable bead 7, making the movable bead 7 contact the connecting pipe 10 tightly. A filter plate 11 is arranged inside the connecting pipe 10. Cooperating with the rubber ring 9 can increase the sealing performance between the air outlet pipe 3 and the connecting pipe 10, and can be engaged with the outside of the resisting plate 5 to increase the sealing performance between the air outlet pipe 3 and the connecting pipe 10;

[0038] Embodiment Two

[0039] As Figure 3-5As shown in the figure, a cover plate is provided on the top of the smelting box 2. Then, the cover plate is removed and the storage battery is placed inside the smelting box 2 for smelting. After smelting, flue gas will be generated. At this time, the flue gas will enter the inside of the connecting pipe 10 through the air outlet pipe 3. At this time, the flue gas will be filtered by the filter plate 11. At this time, the filter plate 11 needs to be cleaned. Telescopic components are provided on both the upper and lower sides inside the connecting pipe 10. The telescopic component includes a cavity 12. The cavity 12 is opened inside the connecting pipe 10. A pull plate 13 is slidably connected inside the cavity 12. Pull the pull plate 13 to both sides. A resilient plate 14 is fixedly connected to the bottom of the pull plate 13. Under the pull of the pull plate 13, the resilient plate 14 slides inside the cavity 12. Two clamping plates 15 are slidably connected to the bottom of the resilient plate 14 near one side. A second spring 16 is fixedly connected to the near side of the two clamping plates 15. The outer parts of the two clamping plates 15 are rotatably connected. The outer part of the resilient plate 14 is slidably connected to the inner wall of the cavity 12. As the resilient plate 14 moves to the through hole of the connecting pipe 10, the resilient plate 14 will be compressed by force. The outer part of the pull plate 13 is slidably connected to the through holes on both sides of the connecting pipe 10. At this time, the two clamping plates 15 are rotated by force. At this time, the second spring 16 is compressed by force. Card slots 17 are opened on both the upper and lower sides of the filter plate 11. The outer bottom end of the clamping plate 15 is engaged with the inner wall of the card slot 17, which can separate the clamping plate 15 from the card slot 17, remove the filter plate 11 for maintenance, and separate the clamping plate 15 from the card slot 17 can quickly disassemble the filter plate 11 without the need to rely on external tools, saving downtime;

[0040] Embodiment 3

[0041] As Figure 3 shown in the figure, an induced draft fan 18 is fixedly connected to the bottom end of the connecting pipe 10. Then, the first spring 8 is started. The other end of the induced draft fan 18 is fixedly connected to a treatment box 19. Driven by the induced draft fan 18, the flue gas will be sucked into the inside of the treatment box 19 and uniformly mixed with the ammonia inside. The bottom of the treatment box 19 is fixedly connected to the top right side of the bottom plate 1. A plurality of catalyst reaction plates 20 are fixedly connected inside the treatment box 19. Then, through the catalyst reaction plates 20, the ammonia reacts with nitrogen oxides to finally generate nitrogen and water. An exhaust pipe is fixedly connected to the top right side of the treatment box 19. Nitrogen is discharged from the exhaust pipe. A water outlet pipe is fixedly connected to the bottom right side of the treatment box 19. Water is discharged through the drain pipe at the bottom.

[0042] Working steps

[0043] Step 1: First, place the bottom plate 1 in a suitable position. Then, dock the air outlet pipe 3 with the connecting pipe 10. When the abutting plate 5 is placed inside the air outlet pipe 3, it will squeeze the movable beads 7 inside the abutting plate 5. At this time, the movable beads 7 will slide on the inner wall of the chute 6 and contact the outside of the connecting pipe 10. Then, slide the locking collar 4 so that the locking collar 4 contacts the movable beads 7 outside the abutting plate 5. At this time, the first spring 8 is compressed under force and will absorb the external force to generate a reaction force on the locking collar 4, making the contact between the locking collar 4 and the movable beads 7 closer. At this time, the locking collar 4 exerts pressure on the movable beads 7, making the contact between the movable beads 7 and the connecting pipe 10 tight. The rubber ring 9 can increase the sealing performance between the air outlet pipe 3 and the connecting pipe 10.

[0044] Step 2: Then, remove the cover plate and put the storage battery into the melting box 2 for melting. After melting, fumes will be generated. At this time, the fumes will enter the inside of the connecting pipe 10 through the air outlet pipe 3. At this time, the fumes will be filtered by the filter plate 11. Then, start the induced draft fan 18. Driven by the induced draft fan 18, the fumes will be sucked into the inside of the treatment box 19 and evenly mixed with the ammonia inside. Then, through the catalyst reaction plate 20, the ammonia will react with nitrogen oxides to finally generate nitrogen and water. The nitrogen is discharged through the exhaust pipe, and the water is discharged through the drain pipe at the bottom. At this time, the filter plate 11 needs to be cleaned. Pull the pull plates 13 to both sides. Driven by the pull plates 13, the elastic plates 14 slide inside the cavity 12. As the elastic plates 14 move to the through holes of the connecting pipe 10, the elastic plates 14 will be compressed under force. At this time, the two clamping plates 15 will rotate under force, and the second spring 16 will be compressed under force, enabling the abutting plate 5 to be separated from the card slots 17, and the filter plate 11 can be removed for maintenance.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
