Description

Technical Field

[0001] The present invention relates to the technical field of liquid flow batteries, and in particular to an electrolyte storage tank for a new energy battery. Background Art

[0002] Liquid flow battery is a new type of battery. It consists of a stack unit, electrolyte, electrolyte storage tube, and management control unit. It is a high-performance battery that separates the positive and negative electrolytes and circulates them separately. The liquid flow battery realizes the mutual conversion of electrical energy and chemical energy through reversible redox reactions of the active substances in the positive and negative electrolyte solutions. During charging, an oxidation reaction occurs at the positive electrode to increase the valence of the active substance, and a reduction reaction occurs at the negative electrode to reduce the valence of the active substance. The discharge process is the opposite. Unlike general solid-state batteries, the positive and negative electrolyte solutions of the liquid flow battery are stored in tanks outside the battery and transported to the inside of the battery for reaction through pumps and pipelines.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This new energy battery electrolyte storage tank has an extraction component installed on the top. The extraction air pump in the extraction component extracts the gas above the electrolyte inside the tank through the air duct.

When the connection between the two protective tanks needs to be released, the locking knob is rotated in the opposite direction and the connecting rod is removed from the inside of the slot, which facilitates maintenance of the surface of the liquid storage tank.

[0018] 4. The electrolyte storage tank of this new energy battery is equipped with a filter box on the liquid outlet pipe. When impurities in the electrolyte need to be processed, the electrolyte in the storage pipe enters the filter box through the pipe.

At the same time, the plug-in plate 19 is inserted into the sealing groove 17, and the inflatable sealing ring 18 is inflated through the air nozzle of the inflatable sealing ring 18, thereby achieving sealing when the two protective tanks 6 are connected to avoid leakage.

[0033] Furthermore, the connecting assembly includes a mounting plate 701, a rotating rod 702, a connecting plate 703, a locking knob 704 and a connecting rod 705. Two mounting plates 701 are installed on the front and rear surfaces of a protective tank 6. The rotating rod 702 is rotatably connected between the two mounting plates 701. A connecting rod 705 is installed on the surface of the rotating rod 702. The surface of the connecting rod 705 is provided with a thread. The surface of the connecting rod 705 is threadedly connected with the locking knob 704. The front and rear surfaces of the other protective tank 6 are both installed with connecting plates 703. One end of the connecting plate 703 is provided with a card slot 20. When the two protective tanks 6 are connected, by rotating the connecting rod 705 so that the connecting rod 705 is located in the card slot 20 on the connecting plate 703, and then rotating the locking knob 704 so that the locking knob 704 and one end of the connecting plate 703 contact each other, the connection and fixation of the two protective tanks 6 can be achieved, thereby realizing the protection of the two protective tanks 6 to the outside of the liquid storage tank 3.

[0034] Furthermore, the leakage detection component includes a hydrogen detector 801 and an alarm 802. A hydrogen detector 801 is installed on the upper end of any protective tank 6. The detection end of the hydrogen detector 801 extends into the interior of the protective tank 6. An alarm 802 is installed on the upper end of the protective tank 6 on one side of the hydrogen detector 801. When the electrolyte leaks, some hydrogen will be generated. The hydrogen detector 801 is used to detect whether the gas between the protective tank 6 and the liquid storage tank 3 contains hydrogen. When hydrogen is detected, the alarm 802 sounds an alarm to remind the staff to take timely action to avoid major safety hazards. The model of the hydrogen detector 801 is GT-1000-H2 hydrogen gas detector. The hydrogen detector 801 controls the alarm 802 through a controller. As for the control principle of the hydrogen detector 801 over the alarm 802, it is a known existing technical means, so it will not be described in detail.

[0035] Furthermore, the extraction component includes an extraction box 1101, an extraction air pump 1102, an air return pipe 1103, an air bleed pipe 1104, a molecular sieve 1105 and a limiting ring 1106. The air bleed pipe 1104 is installed on the other side surface of the installation tube 9. One end of the air bleed pipe 1104 is connected to the extraction air pump 1102. An extraction box 1101 is installed at one end of the extraction box 1101. A return air pipe 1103 is installed between one end of the extraction box 1101 and the tank top 4. A limiting ring 1106 is installed inside the extraction box 1101. A molecular sieve 1105 is installed inside the extraction box 1101 above the limiting ring 1106. By starting the extraction air pump 1102, the extraction The air pump 1102 extracts the gas above the electrolyte in the liquid storage tank 3 through the air duct 1104, and the gas enters the extraction box 1101. The gas contacts the molecular sieve 1105 inside the extraction box 1101. The inert gas in the gas can be discharged from the gap on the molecular sieve 1105 and re-discharged into the liquid storage tank 3 through the return air pipe 1103, thereby achieving the addition of inert gas inside the liquid storage tank 3, which is convenient for the utilization of the electrolyte vapor. The adsorption of gas by the molecular sieve 1105 mainly depends on its pore size and the diameter of the gas molecules. For example, the molecular diameters of nitrogen (N2) and oxygen (O2) are 0.364 and 0.64, respectively. nm and 0.346 nm, so nitrogen can more easily pass through the pores of the molecular sieve 1105, while oxygen will be adsorbed on the surface of the molecular sieve 1105. This selective adsorption property enables the molecular sieve 1105 to effectively separate nitrogen from the mixed gas, thereby realizing the separation of nitrogen, and the upper end of the extraction box 1101 is threadedly connected with a box cover. By removing the box cover, the molecular sieve 1105 inside the extraction box 1101 can be replaced, which is convenient for maintaining the effectiveness of the molecular sieve 1105. In addition, during specific use, the molecular sieve 1105 needs to be replaced regularly to avoid the presence of liquid inside the extraction box 1101.

[0036] Furthermore, a driving motor 21 is installed at the upper end of the mounting tube 9, and a stirring shaft 22 is installed at the output end of the driving motor 21. The stirring shaft 22 passes through the mounting tube 9 and extends to the inside of the liquid storage tank 3. Two stirring blades 23 are installed on the surface of the stirring shaft 22. A number of flow holes 24 are arranged on the surface of the stirring blades 23. By controlling the driving motor 21 to rotate, the driving motor 21 can drive the stirring blades 23 to stir the electrolyte inside the liquid storage tank 3 through the stirring shaft 22, which can break the stratification phenomenon in the electrolyte and make the chemical composition evenly distributed, thereby improving the performance and efficiency of the electrolyte. The setting of the flow holes 24 drives the electrolyte to flow, effectively reducing the resistance of the stirring blades 23 when rotating, thereby reducing the resistance of the driving motor 21 when rotating. Because part of the electrolyte flows from the flow holes 24, it can avoid most of the electrolyte from moving in the same direction with the stirring blades 23, which can increase the relative flow effect between the electrolytes.

[0037] Furthermore, both ends of the filter box 13 are connected to the liquid outlet pipe 12 through a pipe, and multiple limit plates 25 are installed on both sides of the inside of the filter box 13, and a filter layer 26 is installed between the limit plates 25. Control valves 27 are installed on the surface of the pipe and the surface of the liquid outlet pipe 12 between the two ends of the pipe. In daily use, the control valve 27 on the liquid outlet pipe 12 is opened, and the control valve 27 on the pipe is closed, and the electrolyte is directly discharged through the liquid outlet pipe 12. When the electrolyte needs to be filtered, the control valve 27 on the liquid outlet pipe 12 is closed, and the control valve 27 on the pipe is opened, and the electrolyte enters the filter box 13 through the pipe and contacts the filter layer 26 inside the filter box 13, thereby filtering the electrolyte, effectively improving the purity and stability of the electrolyte, and thus improving the performance of the battery. The filter layer 26 is made of nanofiber composite material, which can filter impurities inside the electrolyte.

[0038] Furthermore, a sealing plate 29 is installed at the front end of the filter box 13 by bolts. By removing the sealing plate 29, the filter layer 26 inside the filter box 13 can be replaced to ensure the effectiveness of the filtration of the filter box 13.

[0039] The method of using this embodiment is as follows: first, use two protective tanks 6 to protect the liquid storage tank 3, then move the protective tank 6, and the sliding block 16 under the protective tank 6 slides on the surface of the support rod 15, so that the two contact grooves 28 on the protective tank 6 are in contact with the surface of the mounting tube 9 and the support seat 2, and then rotate the connecting rod 705 so that the connecting rod 705 is located in the card groove 20 on the connecting plate 703, and then rotate the locking knob 704 so that the locking knob 704 contacts one end of the connecting plate 703, so as to realize the connection and fixation of the two protective tanks 6, and inflate the inside of the inflatable sealing ring 18 through the air nozzle. Gas, under the action of the inflatable sealing ring 18 and the sealing gasket, the protective tank 6 can achieve a sealed connection with the liquid storage tank 3. When the liquid storage tank 3 is used, the electrolyte enters the liquid storage tank 3 through the liquid inlet pipe 10 and is discharged to the external battery system through the liquid outlet pipe 12, thereby realizing the use of the electrolyte. In this process, the driving motor 21 can drive the stirring blade 23 through the stirring shaft 22 to stir the electrolyte inside the liquid storage tank 3, thereby breaking the stratification phenomenon in the electrolyte and making the chemical components evenly distributed, thereby improving the performance and efficiency of the electrolyte, and at the same time extracting the air pump 1102 The gas above the electrolyte in the liquid storage tank 3 is extracted through the air duct 1104, and the gas enters the extraction box 1101. The gas contacts the molecular sieve 1105 in the extraction box 1101, and the inert gas in the gas can be discharged from the gap on the molecular sieve 1105 and re-discharged into the liquid storage tank 3 through the return air duct 1103, thereby realizing the addition of inert gas inside the liquid storage tank 3, making it easier to utilize the electrolyte vapor. The hydrogen detector 801 on the protective tank 6 detects whether the gas between the protective tank 6 and the liquid storage tank 3 contains hydrogen. When hydrogen is detected, the alarm is 802 issues an alarm to remind the staff to take timely action to detect electrolyte leakage. When the electrolyte needs to be filtered, the control valve 27 on the liquid outlet pipe 12 is closed and the control valve 27 on the filter box 13 pipeline is opened. The electrolyte passing through the liquid outlet pipe 12 enters the filter box 13 through the pipeline. The electrolyte contacts the filter layer 26 inside the filter box 13. The filter layer 26 can filter the electrolyte, effectively improving the purity and stability of the electrolyte. When the surface of the liquid storage tank 3 needs to be maintained, the two protective tanks 6 can be removed from the surface of the liquid storage tank 3.
