[0033] 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.

[0034] This utility model provides, for example Figure 1-5 The filter device of a flow battery shown includes a filter cartridge 1 and a top cover 2 disposed on the upper side of the filter cartridge 1.

[0035] A slag discharge port 6 is provided at the lower side of the filter cylinder 1. A flushing port 7 is provided at the left and right ends of the lower side of the filter cylinder 1. A feed pipe 8 is provided at the upper left side of the flushing port 7. A discharge pipe 4 is provided at the upper right side of the filter cylinder 1. A fixing block 5 is provided at the left and right ends of the upper side of the filter cylinder 1.

[0036] Three exhaust ports 3 are provided on the upper side of the top cover 2;

[0037] A filter element cylinder 10 is provided at the middle inner side of the filter cylinder 1. A spiral rod 12 is provided at the middle inner side of the filter element cylinder 10. A universal joint structure 11 is connected to the lower side of the spiral rod 12. A spiral tube 14 is provided at the outer side of the spiral rod 12. A bottom ring 13 is provided at the bottom of the spiral tube 14. A top ring 15 is provided at the upper side of the spiral tube 14.

[0038] A connecting block 16 is provided at the connection position between the middle of the universal joint structure 11 and the inside of the filter cylinder 1, and an adjusting rod 9 is provided at the lower end of the universal joint structure 11.

[0039] In this embodiment, the operating principle of the flow battery filtration device is as follows.

[0040] The flow battery filtration device mainly filters impurities in the electrolyte through the filter cartridge 10, while utilizing an innovative structural design to achieve convenient cleaning and operation control.

[0041] Filtration principle: The electrolyte to be filtered enters the filter cartridge 10 through the feed pipe 8. The inner diameter of the filter cartridge 10 performs preliminary filtration of the electrolyte, removing larger particles of impurities. Then, the electrolyte undergoes further fine filtration within the filter cartridge 10, blocking smaller particles of impurities inside the filter cartridge. The filtered electrolyte flows out through the discharge pipe 4 and enters the flow battery system.

[0042] Cleaning principle: After long-term use, a certain amount of filter material will accumulate inside the filter cartridge 10, affecting the filtration effect. At this time, by rotating the adjusting rod 9 on the outside of the filter cartridge 1, the rotation of the adjusting rod 9 is transmitted to the spiral rod 12 through the universal joint structure 11. During the rotation of the spiral rod 12, due to the spiral connection with the spiral tube 14, the spiral tube 14 moves up and down on the spiral rod 12.

[0043] As the spiral tube 14 moves upward, the bottom ring 13 and the top ring 15 move from the upper and lower ends of the filter cartridge 10 towards the middle, respectively, squeezing the filter cartridge 10. This enhances the filtration effect and is suitable for situations requiring higher filtration precision. Simultaneously, this squeezing also helps to further compact impurities within the filter cartridge 10, preparing it for subsequent cleaning.

[0044] As the spiral tube 14 moves downward, the bottom ring 13 and the top ring 15 move towards the upper and lower ends of the filter cartridge 10, respectively, opening the filter cartridge 10. At this time, the flushing liquid in the flushing port 7 enters the filter cartridge 10, flushing out the filtered material inside the filter cartridge 10. Subsequently, the filtered material, propelled by the flushing liquid, exits from the filter cartridge 10 and is then discharged outward through the slag discharge port 6, completing the cleaning process.

[0045] Steps for using the flow battery filter device

[0046] Install:

[0047] The filter cartridge 10 is connected to the filter cartridge 1 by a snap-fit ​​connection to ensure a secure installation and easy disassembly and replacement.

[0048] Check that all components are tightly connected, especially the sealing structure at the connection between the adjusting rod 9 and the filter cartridge 1, to ensure there is no electrolyte leakage.

[0049] Filtering operation:

[0050] The electrolyte to be filtered enters the filter cartridge 10 through the feed pipe 8 and undergoes preliminary filtration under the action of the inner diameter of the filter cartridge 10.

[0051] The electrolyte, after initial filtration, undergoes further fine filtration within the filter cartridge 10. The filtered electrolyte then flows out from the discharge pipe 4 and enters the flow battery system.

[0052] Cleanup operation:

[0053] Stop the flow of electrolyte when you notice a decrease in filtration efficiency or the need for regular cleaning.

[0054] Rotate the adjusting rod 9 on the outside of the filter cylinder 1. The rotation of the adjusting rod 9 is transmitted to the screw rod 12 through the universal joint structure 11.

[0055] The rotation of the screw rod 12 causes the screw tube 14 to move upward on the screw rod 12. The bottom ring 13 and the top ring 15 squeeze the filter cartridge 10, which can enhance the filtration effect and further compact the impurities in the filter cartridge 10.

[0056] Continue rotating the adjusting rod 9 to move the spiral tube 14 downwards, and the bottom ring 13 and top ring 15 move to the upper and lower ends of the filter cartridge 10 respectively, opening the filter cartridge 10.

[0057] Open the flushing port 7 to allow the flushing fluid to enter the filter cartridge 10 and flush out the filtered material inside the filter cartridge 10.

[0058] Driven by the rinsing liquid, the filtered material comes out of the filter cartridge 10 and is then discharged to the outside through the sludge discharge port 6.

[0059] Maintenance and replacement:

[0060] Regularly inspect all components of the filter unit; if any damage or wear is found, replace or repair them individually.

[0061] When the filtration efficiency of filter cartridge 10 decreases, it can be disassembled for cleaning or replaced with a new filter cartridge 10.

[0062] Ensure that the sealing structure at the connection between the adjusting rod 9 and the filter cartridge 1 is always in good condition, and replace the sealing material in time if there is any damage.

[0063] like Figure 1-5 As shown, there are two universal joint structures 11, which are connected by bending at a certain angle. The spiral rod 12 and the uppermost universal joint structure 11 are welded together. The adjusting rod 9 is connected to the lowermost universal joint structure 11 by bolts and is located on the outside of the filter cylinder 1. A sealing structure is provided at the connection between the adjusting rod 9 and the filter cylinder 1. The adjusting rod 9 can rotate on the filter cylinder 1. The spiral rod 12 is connected to the filter element cylinder 10 by a nesting connection and can rotate inside the filter element cylinder 10. The spiral tube is connected to the spiral rod 12 by a spiral connection and can move up and down on the spiral rod 12 by rotation. The bottom ring 13 and the top ring 15 are connected to the spiral tube 14 by a welded connection. The diameters of the bottom ring 13 and the top ring 15 are equal to the inner diameter of the filter element cylinder 10. The filter element cylinder 10 is connected to the filter cylinder 1 by a snap-fit ​​connection. The feed pipe 8 is connected to the inside of the filter element cylinder 10.

[0064] Preferably, the filter cartridge 10 is cylindrical and connected to the filter cartridge 1 via a snap-fit ​​connection, ensuring a secure installation and easy disassembly and replacement. The inner diameter of the filter cartridge 10 is equal to the diameter of the bottom ring 13 and the top ring 15, ensuring that the spiral tube 14 can closely fit the inner wall of the filter cartridge 10 during its up-and-down movement, thereby achieving effective compression and opening of the filter cartridge 10.

[0065] The spiral rod 12 is located in the middle of the inner side of the filter element cylinder 10 and is connected to the filter element cylinder 10 by a nested connection, allowing the spiral rod 12 to rotate freely within the filter element cylinder 10. The lower side of the spiral rod 12 is connected to the universal joint structure 11, providing power transmission for the up and down movement of the spiral tube 14.

[0066] Universal joint structure 11: It consists of two universal rods that are bent and connected at a certain angle. The middle one is connected to the connecting block 16 inside the filter cylinder 1, which serves to connect and transmit power. The uppermost universal rod is welded to the screw rod 12 as a whole to ensure a firm connection and to stably transmit the rotational force of the adjusting rod 9.

[0067] Spiral tube 14: Connected to the spiral rod 12 via a spiral connection, it can move up and down on the spiral rod 12 by means of the spiral action when the spiral rod 12 rotates. A bottom ring 13 is provided at the lower bottom of the spiral tube 14, and a top ring 15 is provided at the upper side. The bottom ring 13 and the top ring 15 are connected to the spiral tube 14 by an integral welding connection. When the spiral tube 14 moves up and down, the bottom ring 13 and the top ring 15 can move separately within the filter cartridge 10, thereby compressing or opening the filter cartridge 10.

[0068] Adjusting rod 9: Located on the outside of filter cylinder 1, it is connected to the bottom universal joint structure 11 by bolts. A sealing structure is provided at the connection between adjusting rod 9 and filter cylinder 1 to prevent electrolyte leakage and ensure smooth rotation of adjusting rod 9 on filter cylinder 1.

[0069] Preferably, to ensure the sealing performance of the filtration device during operation, the sealing structure at the connection between the adjusting rod 9 and the filter cartridge 1 plays a crucial role. This sealing structure uses a special sealing material, which can effectively prevent electrolyte leakage while ensuring that the adjusting rod 9 can rotate flexibly without affecting operation.

[0070] Preferably, the filtration process is as follows: the electrolyte to be filtered enters the filter cartridge 10 through the feed pipe 8 and is filtered by the inner diameter of the filter cartridge 10. The filtered electrolyte flows out through the discharge pipe 4 and enters the flow battery system. During this process, the relative positions of the spiral tube 14, the spiral rod 12, and the filter cartridge 10 remain stable, without affecting the normal operation of the filtration process.

[0071] Cleaning process: After prolonged use of the filter cartridge 10, cleaning is required. The operator rotates the adjusting rod 9, and the rotation of the adjusting rod 9 is transmitted to the spiral rod 12 through the universal joint structure 11. During the rotation of the spiral rod 12, due to its spiral connection with the spiral tube 14, the spiral tube 14 moves up and down on the spiral rod 12.

[0072] As the spiral tube 14 moves upward, the bottom ring 13 and top ring 15 move from the upper and lower ends of the filter cartridge 10 towards the middle, squeezing the filter cartridge 10 and exposing the filtered material inside. At this time, the flushing liquid in the flushing port 7 enters the filter cartridge 10, flushing out the filtered material inside the filter cartridge 10. Subsequently, the filtered material is pushed out of the filter cartridge 10 by the flushing liquid and then discharged to the outside through the slag discharge port 6, completing the cleaning process.

[0073] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
