Description

Technical Field

[0001] This invention belongs to the field of electrode testing technology, specifically relating to a testing device for batch testing of electrode response. Background Technology

[0002] In industrial production and scientific research, the testing of electrode performance is crucial. For example, in the electrolysis of water to produce hydrogen, the tolerance performance of electrode materials is one of the key factors in improving the efficiency of electrolysis of water to produce hydrogen. The testing of electrode tolerance can provide important scientific data for the selection and development of electrodes.

[0003] Currently, the tolerance testing of electrodes is mostly carried out by placing electrode samples in an electrochemical detection station for sampling and testing. However, the existing detection devices have obvious defects. On the one hand, the existing detection devices can only place a portion of the electrode samples in each time, resulting in a small number of samples that are difficult to meet the needs of large-scale testing.

[0004] On the other hand, traditional detection devices cannot simultaneously inject electrolyte into multiple chambers. If multiple electrodes are to be tested separately, electrolyte must be injected into the chamber containing each electrode one by one. This is cumbersome, inefficient, and prone to introducing errors during multiple operations, affecting the accuracy and reliability of the test results.

[0005] In view of the above-mentioned problems in the existing technology, there is an urgent need to develop a technology that allows the electrolyte to enter multiple compartments simultaneously. Utility Model Content

[0006] The purpose of this invention is to provide a testing device for batch detection of electrode response, which can simultaneously detect multiple electrodes and allow electrolyte to enter multiple test chambers at the same time, greatly improving the detection throughput.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A testing device for batch detection of electrode response includes a test frame, wherein a first partition plate is disposed inside the test frame, the first partition plate dividing the interior of the test frame into a test chamber and a lower liquid tank, and a plurality of second partition plates are uniformly fixed on the top of the first partition plate, the second partition plates dividing the test chamber into a plurality of test compartments.

[0009] A fixed tube is installed inside the first partition plate and at a position corresponding to each of the test chambers. A liquid-passing structure is provided inside the fixed tube, which is used to pass the liquid in the lower liquid chamber into each of the test chambers.

[0010] The bottom of the test frame is equipped with an inlet pipe and an outlet pipe, and both the inlet pipe and the outlet pipe are connected to the lower liquid tank.

[0011] The liquid-passing structure includes a blocking plate and a mounting plate fixed inside the fixed tube. The mounting plate is located on top of the blocking plate. A liquid-passing groove is provided at the center of the blocking plate. A liquid-inlet groove is provided inside the mounting plate. A spring is fixed to the bottom of the mounting plate, and a blocking block is fixed to the bottom of the spring. The blocking block is inserted into the liquid-passing groove.

[0012] An electromagnet is installed inside the mounting plate and on top of the blocking block.

[0013] A telescopic rod is installed between the mounting plate and the blocking block, and inside the spring.

[0014] The outer side of the fixed tube is provided with a threaded wire, and the inside of the test chamber and at the position corresponding to the threaded wire are provided with a threaded groove, and the threaded wire is threadedly connected to the threaded groove.

[0015] A raw rubber tape is provided between the threaded wire and the threaded groove.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention sets up multiple test chambers, thereby simultaneously detecting multiple electrodes. By using a fixed tube between the lower liquid chamber and the test chambers, the electrolyte can enter multiple test chambers at the same time, which greatly improves the detection throughput compared to traditional devices that can only detect a portion of the electrode samples at a time.

Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4 As shown, a testing device for batch detection of electrode response includes a test frame 1, a first partition plate 6 is provided inside the test frame 1, the first partition plate 6 divides the interior of the test frame 1 into a test chamber and a lower liquid tank 4, and a plurality of second partition plates 7 are uniformly fixed on the top of the first partition plate 6, the second partition plates 7 divide the test chamber into a plurality of test compartments 5.

[0026] When testing the electrodes, the electrode to be tested, the counter electrode, and the reference electrode can be inserted into the test chamber 5, which is filled with electrolyte, so that the test can be performed. By inserting the electrodes into multiple test chambers 5 for testing, the test chambers 5 can be tested in batches. The above principle is existing technology and will not be elaborated here.

[0027] A fixed pipe 8 is installed inside the first partition plate 6 and at the corresponding position of each test chamber 5. A liquid passage structure is provided inside the fixed pipe 8, which is used to pass the liquid in the lower liquid chamber 4 into each test chamber 5.

[0028] The bottom of the test frame 1 is equipped with an inlet pipe 2 and an outlet pipe 3, both of which are connected to the lower liquid tank 4. The inlet pipe 2 is used to introduce electrolyte into the test frame 1, while the outlet pipe 3 is used to discharge electrolyte. The inlet pipe 2 and the outlet pipe 3 can be connected to external drive structures such as water pumps.

[0029] See attached document Figure 3The liquid-passing structure includes a blocking plate 9 and a mounting plate 11 fixed inside the fixed tube 8. The mounting plate 11 is located on top of the blocking plate 9. A liquid-passing groove 18 is provided at the center of the blocking plate 9. A liquid-inlet groove 13 is provided inside the mounting plate 11. A spring 12 is fixed to the bottom of the mounting plate 11, and a blocking block 10 is fixed to the bottom of the spring 12. The blocking block 10 is inserted into the liquid-passing groove 18. According to the above structure, a telescopic rod 19 is installed between the mounting plate 11 and the blocking block 10 and inside the spring 12. By setting the telescopic rod 19, the spring 12 can compress the telescopic rod 19 when compressed, thereby preventing the blocking block 10 from tilting.

[0030] During operation, electrolyte is first introduced into the test frame 1 through the inlet pipe 2. The liquid first enters the lower liquid tank 4. As the lower liquid tank 4 gradually overflows, it enters the interior of multiple fixed pipes 8, lifting the blocking block 10 and compressing the spring 12. This allows the liquid to enter multiple test chambers 5 from the liquid passage trough 18 and the inlet trough 13. After the liquid in the test chamber 5 reaches a certain height, the inlet pipe 2 stops supplying liquid. At this time, the outlet pipe 3 begins to drain the liquid. The blocking block 10 stops being lifted and is reset by the spring 12, sealing the liquid passage trough 18. The liquid in the lower liquid tank 4 is then completely discharged through the outlet pipe 3, making the multiple test chambers 5 completely independent chambers.

[0031] See attached document Figure 3 An electromagnet 14 is installed inside the mounting plate 11 and on top of the blocking block 10. The blocking block 10 has a magnet or iron block inside, so that when the electromagnet 14 is driven, it can attract the blocking block 10. When the liquid in the test chamber 5 needs to be discharged, the electromagnet 14 can be driven to attract the blocking block 10, thereby exposing the liquid tank 18. The liquid in the test chamber 5 is discharged into the lower liquid tank 4 through the fixed pipe 8, and then discharged through the liquid outlet pipe 3. The liquid discharged through the liquid outlet pipe 3 can be recycled and reused through filtration or other structures.

[0032] See attached document Figure 4 The outer side of the fixed tube 8 is provided with a threaded wire 15, and the inner side of the test chamber 5 is provided with a threaded groove 16 at the position corresponding to the threaded wire 15. The threaded wire 15 and the threaded groove 16 are threadedly connected. When it is necessary to clean the inside of the fixed tube 8, the fixed tube 8 can be disassembled through the threaded wire 15 and the threaded groove 16, so as to facilitate the cleaning of the fixed tube 8. Furthermore, a raw rubber tape 17 is provided between the threaded wire 15 and the threaded groove 16. The raw rubber tape 17 can improve the sealing effect at the threaded connection of the threaded wire 15 and the threaded groove 16, and prevent leakage.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
