Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a VOCs treatment device in the process of crushing and recycling waste power lithium batteries. Background Technology

[0002] Thermal desorption is a process that uses direct or indirect heat exchange to heat the polluting medium and its contained organic pollutants to a sufficient temperature, allowing the organic pollutants to volatilize or separate from the polluting medium. In recent years, the environmental impact of waste batteries has become a hot topic in domestic media. Whether in the atmosphere or buried deep underground, waste batteries leach heavy metals, causing pollution of groundwater and soil, which can seriously endanger human health over time. Currently, waste lithium batteries can be effectively recycled by crushing and recycling to recover zinc-iron alloys or manganese-iron alloys. At the same time, metals such as zinc, manganese, and iron stored in waste lithium batteries can also be recovered and reused.

[0003] Currently, when processing waste lithium batteries, the waste gas generated after crushing needs to be heated for separation. However, since the waste gas contains dust, it affects the processing results during heating and decomposition. Therefore, the waste gas needs to be filtered before heating. However, since most devices process a large amount of waste gas at once, the filter needs to be replaced frequently. When the filter needs to be replaced, most devices have to stop operating to replace the filter, resulting in multiple pauses when long-term processing is required, increasing working time and reducing device efficiency. To solve this problem, we propose a VOCs treatment device for the crushing and recycling process of waste power lithium batteries. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a VOCs treatment device during the crushing and recycling process of waste power lithium batteries, comprising:

[0025] Machine tool 1, pyrolysis furnace 2 is installed on machine tool 1, two sets of filter chambers 31 are installed on machine tool 1, a fixing frame is set between the two sets of filter chambers 31, and an air inlet pipe 9 is connected between filter chamber 31 and pyrolysis furnace 2.

[0026] A conversion mechanism is installed on machine tool 1;

[0027] The conversion mechanism includes an outer sleeve 3, which is fixedly connected to the machine tool 1. The outer sleeve 3 has a set of air inlets 5 and two sets of exhaust ports 4. An inner sleeve 6 is rotatably sleeved inside the outer sleeve 3. The inner sleeve 6 has a first conversion port 7 and a second conversion port 8. Both sets of exhaust ports 4 are fixedly connected to air supply pipes 10. The two sets of air supply pipes 10 are fixedly connected to the filter chamber 31. A drive assembly is provided on the inner sleeve 6. A screw 20 is threaded inside the drive assembly. Both ends of the screw 20 are rotatably connected to a drive rack 21. The drive rack 21 is slidably connected to the outer surface of the filter chamber 31. A drive gear 22 is meshed on the drive rack 21. An opening and closing assembly is fixedly installed on the drive gear 22. The opening and closing assembly is respectively located inside the air inlet pipe 9.

[0028] When the drive assembly starts, the inner sleeve 6 will rotate until the first conversion port 7 contacts the exhaust port 4. At this time, the exhaust gas will enter the inner sleeve 6 from the air inlet 5 through the second conversion port 8, and then enter the interior of a set of filter chambers 31 through the first conversion port 7 along the interior of the air supply pipe 10. At the same time, the drive assembly will drive the screw 20 to move, and then drive the drive gear 22 to rotate through the drive rack 21. At this time, the opening and closing component inside the air inlet pipe 9 connected to the set of filter chambers 31 in use will open, and the opening and closing component inside the air inlet pipe 9 of the unused set of filter chambers 31 will close.

[0029] The drive assembly includes a drive motor 14, which is fixedly mounted on a frame between two filter chambers 31. The output end of the drive motor 14 is fixedly connected to a drive shaft 15. A transmission pulley 13 is fixedly sleeved on the drive shaft 15. A drive pulley 11 is fixedly connected to the inner sleeve 6. A drive toothed belt 12 meshes between the drive pulley 11 and the transmission pulley 13. A drive bevel gear 16 is fixedly connected to the drive shaft 15. A driven bevel gear 17 meshes with the drive bevel gear 16. A worm gear 18 is rotatably connected to the driven bevel gear 17. The worm gear 18 rotatably passes through the frame. A worm wheel 19 meshes with the worm gear 18. The worm wheel 19 is rotatably connected to the frame. An internal threaded sleeve is provided inside the worm wheel 19, which is threadedly sleeved with the screw 20.

[0030] When the drive motor 14 starts, the drive shaft 15 will drive the transmission pulley 13 to rotate, which in turn will drive the drive pulley 11 to rotate via the drive toothed belt 12. At this time, the drive pulley 11 will drive the inner sleeve 6 to rotate. Simultaneously, the drive shaft 15 will drive the driven bevel gear 17 to rotate via the drive bevel gear 16, which in turn will drive the worm wheel 19 to rotate via the worm 18. At this time, the internal threaded sleeve inside the worm wheel 19 will drive the screw 20 to move left and right while rotating.

[0031] The opening and closing assembly includes a rotating shaft 26, which is fixedly connected to a drive gear 22. A first rotating bevel gear 23 is fixedly sleeved on the rotating shaft 26. A second rotating bevel gear 24 is meshed on the first rotating bevel gear 23. The second rotating bevel gear 24 is rotatably connected to the outer surface of the air intake pipe 9. A third rotating bevel gear 25 is meshed on the second rotating bevel gear 24. A rotating sleeve rod 27 is fixedly connected to the third rotating bevel gear 25. The rotating sleeve rod 27 is rotatably sleeved on the surface of the rotating shaft 26. A second baffle plate 29 is fixedly connected to the rotating sleeve rod 27. A first baffle plate 28 is fixedly connected to the rotating shaft 26.

[0032] When the drive gear 22 drives the rotating shaft 26 to rotate, it will drive the first rotating bevel gear 23 to rotate. At this time, the rotating shaft 26 will drive the first baffle plate 28 to rotate. Meanwhile, the first rotating bevel gear 23 will drive the third rotating bevel gear 25 to rotate in the opposite direction through the second rotating bevel gear 24, and then drive the second baffle plate 29 to rotate through the rotating sleeve rod 27.

[0033] Among them, the top end of the drive shaft 15 is fixedly connected to a limiting block 30, the limiting block 30 is fixedly connected to a limiting plate 33, the limiting plate 33 is provided with a limiting groove, and the limiting block 30 contacts the limiting groove on the limiting plate 33.

[0034] Due to the setting of the limiting plate 33, the driving shaft 15 will be limited by the limiting block 30 when it rotates.

[0035] The filter chamber 31 has an extraction slot inside, and a filter element 32 is installed inside the extraction slot. One end of the filter element 32 is fixed to the surface of the filter chamber 31 by bolts.

[0036] The extraction slot makes it easy to replace the filter element 32.

[0037] The pyrolysis furnace 2 is fixedly connected to an exhaust pipe, and the bottom of the pyrolysis furnace 2 is fixedly connected to a drain pipe. Valves are installed on both the drain pipe and the exhaust pipe.

[0038] The installation of exhaust and drainage pipes facilitates the discharge of substances decomposed inside the pyrolysis furnace 2.

[0039] Working principle and usage process of this utility model:

[0040] When it is necessary to clean and replace the inside of a set of filter chambers 31, the drive motor 14 is started. At this time, the transmission pulley 13 will drive the drive pulley 11 to rotate through the drive toothed belt 12, thereby driving the inner sleeve 6 to rotate inside the outer sleeve 3. At this time, the first conversion port 7 and the second conversion port 8 will be connected to a set of exhaust ports 4 and air inlets 5 respectively during the rotation. At this time, the other set of exhaust ports 4 will be closed through the outer wall of the inner sleeve 6, thereby connecting to a set of air supply pipes 10. At this time, a set of filter chambers 31 is connected to a set of air supply pipes 10, thus preventing the other set of filter chambers 31 from passing through exhaust gas, thereby achieving the effect of convenient replacement of filter elements without stopping the device.

[0041] Meanwhile, the drive shaft 15 drives the driven bevel gear 17 to rotate via the drive bevel gear 16, which in turn drives the worm wheel 19 to rotate via the worm 18. At this time, the internal threaded sleeve inside the worm wheel 19 drives the screw 20 to rotate, which in turn drives the two sets of drive racks 21 to move. During this movement, one set of drive racks 21 drives the rotating shaft 26 to rotate via the drive gear 22, which in turn drives the first baffle plate 28 to rotate. Simultaneously, the rotating shaft 26 drives the first rotating bevel gear 23 to rotate, which in turn drives the third rotating bevel gear 25 to rotate in the opposite direction via the second rotating bevel gear 24. 25 will drive the second baffle plate 29 to rotate via the rotating sleeve 27. At this time, the first baffle plate 28 and the second baffle plate 29 will tend to open, thereby making a set of air inlet pipes 9 connected. At the same time, another set of drive racks 21 will drive the rotating shaft 26 to rotate in the opposite direction via the drive gear 22, thereby causing the first baffle plate 28 and the second baffle plate 29 to close. At this time, the other set of air inlet pipes 9 will be closed, thereby facilitating the closure of a set of filter chambers 31. This prevents the interior of the set of filter chambers 31 that need to be cleaned from communicating with the pyrolysis furnace 2, thereby preventing the gas inside the pyrolysis furnace 2 from flowing back into the interior of the filter chambers 31 that need to be sealed through the air inlet pipes 9.
