Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragm waste gas treatment, in particular to a purification device for lithium battery diaphragm waste gas treatment. Background Art

[0002] Waste gas is generated during the production process of lithium battery diaphragms, and the waste gas needs to be purified during the production process. After searching, the patent with publication number CN219848644U discloses a lithium battery diaphragm waste gas treatment and purification equipment. When in use, the liquid inlet pipe, air inlet pipe and exhaust pipe are respectively connected to the external pipe, and then the lithium battery diaphragm waste gas enters the filter cavity through the air inlet pipe. At this time, the solid particle impurities in the waste gas are filtered through the filter mesh, and the filtered waste gas enters the treatment cavity. At this time, the purification liquid is transported to the inside of the nozzle through the liquid inlet pipe through the external equipment, and then the nozzle is evenly sprayed inside the treatment cavity to realize the spray purification treatment of the waste gas. After that, the waste gas enters the inside of the connecting pipe. At this time, the ultraviolet lamp is started to purify the waste gas inside the connecting pipe again. Ultraviolet sterilization and disinfection treatment is carried out, and finally the purified gas is discharged through the exhaust pipe. However, it is filtered through the filter. As the filtration proceeds, filter residues accumulate on the filter, so that the filtration efficiency will become lower and lower, and the purification speed will become slower and slower. At the same time, it is only filtered through the filter, and all the filter residues must be filtered by the filter, which puts a heavy filtration burden on the filter. For this reason, a purification equipment for lithium battery diaphragm waste gas treatment is designed, which is convenient for fine filtration after coarse filtration. At the same time, the coarse filtration is dry filtration and the fine filtration is wet filtration. The filter residue from the coarse filtration is collected during the dry filtration, and the wet filtration effect is guaranteed during the wet filtration. The wet filtered gas is dried before discharge to ensure the dryness of the filtered gas. Utility Model Content

[0020] 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 embodiments 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.

[0021] Example:

[0022] See also Figure 1-3, a purification device for treating lithium battery diaphragm waste gas, comprising a frame 1, on which an air inlet pipe 5, a dry coarse filtration mechanism, a wet fine filtration mechanism, a drying mechanism and an air outlet pipe 8 are sequentially arranged and connected. The dry coarse filtration mechanism comprises a vertical tank 2 fixedly mounted on the frame 1 and connected to the air inlet pipe 5 and the wet fine filtration mechanism. The bottom of the vertical tank 2 is detachably connected to a slag collecting bottle 12. A material separation component is provided on the side of the vertical tank 2 opposite to the air inlet pipe 5. The wet fine filtration mechanism comprises a purified liquid tank 3 fixedly mounted on the frame 1 and connected to the vertical tank 2 and the drying mechanism on both sides. A filter plate 1 is vertically fixedly mounted in the middle of the purified liquid tank 3 3. The middle part of the filter plate 13 is sealed and rotated and slidably matched with a filter disc 14. An X-shaped frame 15 for hanging materials is provided on one side of the filter disc 14 close to the side of the vertical tank 2. The X-shaped frame 15 is fixedly connected to the inner wall of the purified liquid tank 3, and also includes a filtering and dredging mechanism for driving the filter disc 14 to rotate. Further, the slag collecting bottle 12 is connected to the bottom of the vertical tank 2 by a thread. Further, the drying mechanism includes a drying box 4 fixedly mounted on the frame 1, and the air outlet pipe 8 is connected to the output end of the drying box 4. Further, an X-shaped frame 15 is also provided on the other side of the filter disc 14, and the filter disc 14 can be limited by two X-shaped frames 15.

[0023] Specifically, the material separation assembly includes a spherical cover 9 which is integrally fixed and connected to the vertical tank 2 on the side opposite to the air inlet pipe 5. A slag rack 10 is rotatably connected inside the spherical cover 9, so that the spherical cover 9 is arranged on the side opposite to the air inlet pipe 5. When the exhaust gas is introduced into the vertical tank 2 through the air inlet pipe 5, the slag rack 10 can be directly driven to rotate. When the slag rack 10 rotates clockwise, some impurities can be pushed to the bottom of the vertical tank 2, so that the impurities can be collected by the slag collecting bottle 12 at the bottom.

[0024] Specifically, the air inlet pipe 5 is set to a bent structure, and the free end of the air inlet pipe 5 is in a horizontal state. The connection between the air inlet pipe 5 and the vertical tank 2 is tilted upward. By setting the air inlet pipe 5 to a bent structure, it is convenient for the air inlet pipe 5 to be connected with the exhaust gas inlet pipe, and at the same time, it is convenient to make the exhaust gas in the vertical tank 2 blow upward. When part of the exhaust gas drives the slag rack 10 to rotate, part of the exhaust gas flows directly to the top of the vertical tank 2.

[0025] Specifically, the filtering and dredging mechanism includes a driving motor 17 fixedly mounted on the purified liquid tank 3, the filter disc 14 is sealed and rotatably connected to the purified liquid tank 3 through a rotating shaft 16, the output shaft of the driving motor 17 is fixedly connected to the rotating shaft 16, and the driving motor 17 is started to conveniently drive the rotating shaft 16 to rotate, thereby driving the filter disc 14 to rotate. When the filter disc 14 rotates, it cooperates with the X-shaped frame 15 to hang down the impurities on the filter disc 14, thereby ensuring the filtering effect of the filter disc 14.

[0026] Specifically, the top of the purified liquid tank 3 is located on both sides of the filter disc 14 and is connected to the top of the vertical tank 2 and the input end of the drying mechanism through connecting pipe 1 6 and connecting pipe 2 7 respectively. The setting of connecting pipe 1 6 and connecting pipe 2 7 facilitates the connection between the vertical tank 2 and the purified liquid tank 3 and between the purified liquid tank 3 and the drying box 4.

[0027] Specifically, the top and bottom ends of the purified liquid tank 3 are respectively provided with a liquid filling plug 18 and a sewage discharge valve 19. The sewage discharge valve 19 is arranged at the bottom of the side close to the connecting pipe 6. Furthermore, the liquid filling plug 18 can be set as a rubber plug, which can be conveniently used to add purified liquid into the purified liquid tank 3 through a needle tube, and by opening the sewage discharge valve 19, the purified sewage can be conveniently discharged.

[0028] Specifically, the top of the vertical tank 2 is set to be conical, and a plurality of slag retaining rings 11 are sequentially provided on the inner top of the vertical tank 2 from bottom to top. The plurality of slag retaining rings 11 facilitate the attenuation of the exhaust gas flowing from bottom to top, so that some impurities fall down.
