Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrolyte solvent production, in particular to an electrolyte heating device. Background Art
[0002] Electrolyte is the medium used in chemical batteries, which mainly plays the role of electrochemical reaction and conductivity. In the production process of batteries, heating the electrolyte is an indispensable step. By heating the electrolyte, the shelf time of the electrolyte can be effectively reduced, the wetting ability of the electrolyte can be improved, and the white stripe phenomenon can be prevented from appearing on the diaphragm inside the battery cell.
[0003] For example, the patent with announcement number CN206927953U discloses an electrolyte heating device, which uses a heating chamber to cooperate with a natural gas heater. With this structure of the heating device, the electrolyte flows in the tank body and is heated by the high-temperature flue gas generated by the combustion of natural gas in the heating chamber. The flue gas passes through the smoke chamber at the rear of the tank body and then enters the heating pipe to perform secondary heating on the electrolyte. Based on this heating device, actual research has found that although the high-temperature flue gas from the combustion of natural gas can achieve the heating effect on the electrolyte, it is difficult to avoid causing contamination of the electrolyte.
[0004] In this regard, for example, the patent with announcement number CN218530857U discloses a heating device for the production of electrolyte solvents, which achieves the heating effect of the electrolyte in the main treatment tank by evenly welding an extended inner rod on the inner side of the main treatment tank in coordination with the main treatment tank, and the inner side of the extended inner rod is plugged with a heating wire. Although this structure can prevent the flue gas produced by the combustion of natural gas from polluting the electrolyte, the overall heating wire extends into the main treatment tank, making maintenance difficult. In addition, as the temperature inside the main treatment tank increases, the electrolyte is stirred to discharge the gas in the electrolyte, which will form a high-pressure environment inside the main treatment tank. If the high-pressure gas cannot be discharged in time, it may cause safety hazards.
[0005] Therefore, in view of the problems existing in the use of the electrolyte heating device used in the prior art, it is necessary to further optimize the overall structure of the electrolyte heating device. Utility Model Content

DETAILED DESCRIPTION
[0030] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.
[0031] Embodiment 1:
[0032] See also Figures 1 to 3 As shown, this embodiment provides an electrolyte heating device, including: a heating cylinder 5 and a heating component 2 and a one-way valve exhaust component 3 arranged on the heating cylinder 5 .
[0033] Specifically, the heating cylinder 5 includes a cylinder body 51 for containing electrolyte and a cylinder cover 52 disposed on the top of the cylinder body 51; the cylinder body 51 includes an inner cavity 10 and an outer cavity 14 disposed on the circumferential outer side of the inner cavity 10. The cylinder cover 52 is also provided with a liquid filling port for adding electrolyte into the inner cavity 10; and a liquid discharge pipe 7 is provided at the bottom of the cylinder body 51. A hydraulic control valve 6 is fixedly installed on the outer side of the liquid discharge pipe 7.
[0034] Next is the heating assembly 2, which includes a plurality of heating devices arranged in an array in the outer cavity 14. For example, in an optional implementation, each heating device is a heating rod 18. The heating rod 18 here can be any mature means in the prior art, and its specific model and heating principle are not described in detail in this embodiment.
[0035] For the disassembly and assembly process of the heating rod 18 of this embodiment, each heating device further includes a threaded rod 16 connected to the heating rod 18; the threaded rod 16 is threadedly matched with the cylinder cover 52. In order to improve the convenience of the disassembly and assembly process of the heating rod 18, a handle 15 located above the cylinder cover 52 is further provided at one end of the threaded rod 16 facing away from the heating rod 18. A sealing gasket 17 is provided between the handle 15 and the threaded rod 16, and the sealing gasket 17 cooperates with the cylinder cover 52 to ensure the airtightness inside the outer cavity 14.
[0036] Based on the above situation, in an optional implementation, an oil agent is provided in the outer cavity 14, and the heating rod 18 is adapted to be partially inserted into the oil agent in the outer cavity 14. The specific heat capacity of the oil agent is much greater than that of the water agent, and thus the oil agent can fully conduct heat to the electrolyte, thereby improving the heating efficiency of the electrolyte in the inner cavity 10.
[0037] Next is the one-way valve exhaust assembly 3, which includes a valve body 19 disposed on the barrel cover 52 and connected to the inner cavity 10, an exhaust hole 21 provided on the side wall of the valve body 19, and an elastic member 20 disposed in the valve body 19 and a valve core 22 suitable for pushing one end of the elastic member 20; wherein the exhaust hole 21 is disposed on the portion of the valve body 19 located above the barrel cover 52. The elastic member 20 here can be a spring.
[0038] Based on the above structure, when the valve core 22 is located on the side of the exhaust hole 21 facing the inner cavity 10, the valve core 22 is suitable for forming a partition for the flow of gas between the exhaust hole 21 and the inner cavity 10; when the valve core 22 is located on the side of the exhaust hole 21 facing away from the inner cavity 10, the exhaust hole 21 is communicated with the inner cavity 10.
[0039] In more detail with reference to the drawings, the valve body 19 has a cylindrical inner cavity; the valve core 22 is a spherical body; and the outer diameter of the valve core 22 is equal to the inner diameter of the cylindrical inner cavity.
[0040] In addition, it should be noted that, in order to meet the use requirements of the valve core 22, a bracket 23 suitable for supporting the valve core 22 is also provided in the cylindrical inner cavity and located on the side of the exhaust hole 21 facing the inner cavity 10. Based on this structure, it is necessary to explain that the top of the overall valve body 19 away from the inner cavity 10 is an open opening that can be opened, and the end of the valve body 19 facing the inner cavity 10 is a connecting hole connected to the inner cavity 10. The open opening is equipped with a valve cover, and the elastic member 20 and the valve core 22 are both installed into the cylindrical inner cavity from the open opening. In the natural elastic state of the elastic member 20, the bracket 23 forms a supporting effect on the side of the valve core 22 facing away from the elastic member 20, thereby preventing the valve core 22 from detaching from the valve body 19 from the connecting hole due to gravity.
[0041] It should also be explained that, regarding the electrolyte heating device of this embodiment, a stirring assembly for stirring the electrolyte is also provided in the inner cavity 10 thereof; and a power structure for penetrating the cylinder cover 52 to drive the stirring assembly to operate is also provided on the cylinder cover 52. The stirring assembly here can be selected by any mature means in the prior art, and this embodiment does not make an absolute limitation on this. For example, as shown in the accompanying drawings, the stirring assembly includes a stirring rod 11, a stirring disk 12 connected to the stirring rod 11, and a stirring blade 13 provided on the stirring disk 12; the power structure can be selected by, for example, but not limited to, a motor 4. The design of the stirring assembly can evenly and fully stir the electrolyte in the inner cavity 10, so that the internal gas can be quickly discharged.
[0042] In summary, for the electrolyte heating device of this embodiment, when in use, the heating rod 18 is inserted into the outer cavity 14, and the heating rod 18 heats the oil agent. The specific heat capacity of the oil agent is much larger than that of the water agent, and thus the heat can be fully conducted to the electrolyte. The heating component 2 is arranged in the outer cavity 14, which can not only form an isolation from the electrolyte in the inner cavity 10 to prevent it from causing contamination to the electrolyte, but also facilitate maintenance. Furthermore, through the designed one-way valve exhaust assembly 3, as the temperature of the electrolyte increases during heating, when the gas in the electrolyte is discharged, the air pressure inside the inner cavity 10 increases rapidly, and the air pressure pushes the valve core 22 toward the side of the tube cover 52, so that the valve core 22 slides along the valve body 19. When the valve core 22 slides to above the exhaust hole 21, the high-pressure gas inside the inner cavity 10 is discharged through the exhaust hole 21. When the air pressure inside the inner cavity 10 decreases, the valve core 22 moves downward under the resetting action of the elastic member 20 and the action of gravity, thereby isolating the exhaust hole 21 and the inner cavity 10, avoiding the backflow of external gas, thereby improving the safety and reliability of the electrolyte heating process.
[0043] Embodiment 2:
[0044] See also Figures 1 to 4As shown, based on the electrolyte heating device of Example 1, the electrolyte heating device provided in this embodiment further includes a mobile platform for supporting the heating cylinder 5. The mobile platform is used to drive the heating cylinder 5 to move, thereby improving the convenience and flexibility of the use process of the heating cylinder 5. The mobile platform here can be selected as a simplified mobile bracket 1 and a leg 9 provided at the bottom of the mobile bracket 1, and the leg 9 is equipped with a roller 8.
