Description

Technical Field

[0001] This utility model relates to the field of nitrogen detection technology for flow channel plates, specifically a nitrogen detection tooling for flow channel plates. Background Technology

[0002] Flow channels are widely used in semiconductors, fuel cells, chemical equipment, and other fields, and their sealing performance directly affects the operating efficiency and safety of the equipment. In actual production, flow channels may have tiny cracks, holes, or other defects, leading to nitrogen leakage and affecting the normal operation of the equipment. Therefore, nitrogen testing of flow channels is a crucial step in ensuring their quality. Nitrogen testing, as a commonly used detection method, is widely used in industrial production due to its simplicity, low cost, and minimal environmental impact.

[0003] In existing technologies, although nitrogen detection methods can test the sealing performance of flow channel plates, the nitrogen cannot be recovered and reused after detection and is directly emitted into the atmosphere, resulting in resource waste and increased detection costs. This defect not only increases the operating costs of enterprises in practical applications, but also violates the requirements of modern industry for efficient resource utilization and environmental protection. Utility Model Content

[0004] The purpose of this invention is to provide a nitrogen inspection fixture for flow channel plates to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A nitrogen inspection fixture for flow channel plates, including

[0007] The detection pool has a reduction pool fixedly installed on its right side, and a lifting mechanism is provided at the upper end of the detection pool.

[0009] Preferably, the lifting mechanism includes a frame, which is fixedly installed at the top of the detection pool. An electric push rod is fixedly installed at the top middle part of the frame.

[0012] Preferably, the recycling mechanism includes an input pipe, the detection tank is connected to the input end of the circulation pump via the input pipe, and the lower interior of the reduction tank is connected to the other end of the circulation pump via an output pipe;

[0013] Preferably, the recycling mechanism further includes a reversing valve, which is fixedly installed at the connection between the input pipe and the circulation pump. The other end of the reversing valve is connected to an air inlet pipe, the top end of which passes through the reduction tank and is located at the upper end of the reduction tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This flow channel plate nitrogen inspection fixture, through a nitrogen recovery system, can recover the used nitrogen during the inspection process, avoiding direct emission into the atmosphere and causing resource waste. It not only reduces the cost of nitrogen use, but also meets the requirements of modern industry for efficient resource utilization, saving operating costs for enterprises.

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution:

[0024] A flow channel plate nitrogen detection fixture includes a detection tank 1, a reduction tank 2 fixedly installed on the right side of the detection tank 1, a lifting mechanism provided at the upper end of the detection tank 1, the lifting mechanism including a frame 4, the frame 4 fixedly installed at the top of the detection tank 1, an electric push rod 5 fixedly installed at the top middle part of the frame 4, a lifting plate 6 fixedly installed at the output shaft end of the electric push rod 5, hangers 7 fixedly installed on both sides of the bottom end of the lifting plate 6, perforated support plates 8 fixedly installed at the bottom ends of the two hangers 7, corrugated pipes 9 connected to the upper and lower ends of the right side of the lifting plate 6, a nitrogen inlet 10 fixedly installed at the top right side of the frame 4, the upper corrugated pipe 9 connected to the nitrogen inlet 10, a connector 11 fixedly installed at the bottom end of the lower corrugated pipe 9, and a replenishment pipe 12 and a discharge pipe 13 connected to the upper and lower ends of the left side of the detection tank 1, respectively.

[0025] In this embodiment, sodium bicarbonate solution is used as the detection liquid, and a pH indicator is added to achieve the liquid color change effect. When nitrogen enters the detection tank 1, the liquid will change from colorless to pink, which intuitively shows whether there is a leak in the flow channel plate. The detection method based on liquid color change is more intuitive than the traditional nitrogen detection method, and can quickly determine the sealing performance of the flow channel plate, thus improving the detection efficiency.

[0026] like Figure 2 and Figure 4 As shown, a circulation pump 3 is fixedly installed at the upper end of the inside of the reduction tank 2. A recovery mechanism is provided between the circulation pump 3, the detection tank 1, and the reduction tank 2. The recovery mechanism includes an input pipe 14. The input end of the detection tank 1 is connected to the input end of the circulation pump 3 via the input pipe 14. An output pipe 15 is connected to the lower inside of the reduction tank 2 and the other end of the circulation pump 3. The recovery mechanism also includes a reversing valve 16. The reversing valve 16 is fixedly installed at the connection between the input pipe 14 and the circulation pump 3. The other end of the reversing valve 16 is connected to an air inlet pipe 17. The top end of the air inlet pipe 17 passes through the reduction tank 2 and is located at the upper end of the reduction tank 2. A recovery pipe 18 is connected to the lower right side of the reduction tank 2.

[0027] In this embodiment, the nitrogen recovery system can recover the used nitrogen during the detection process, avoiding direct emission into the atmosphere and thus avoiding resource waste. This not only reduces the cost of nitrogen use but also meets the requirements of modern industry for efficient resource utilization, saving operating costs for enterprises.

[0028] Working Principle: First, the outlet end of the flow channel plate is sealed to ensure that nitrogen does not leak from the outlet. Then, the sealed flow channel plate is placed on the perforated support plate 8. Next, the inlet of the flow channel plate is connected to the connector 11 to ensure that nitrogen can smoothly enter the interior of the flow channel plate. Subsequently, the lifting plate 6 is lowered by the electric actuator 5, immersing the flow channel plate in the sodium bicarbonate solution (with added phenolphthalein) in the detection tank 1. Then, nitrogen is introduced into the upper corrugated pipe 9 through the nitrogen inlet 10. The nitrogen enters the interior of the flow channel plate through the corrugated pipe 9 and the connector 11, flows inside the flow channel plate, and finally enters the liquid in the detection tank 1 through the holes of the perforated support plate 8. When the nitrogen enters the detection tank 1, it replaces the dissolved oxygen in the liquid, causing the pH value of the sodium bicarbonate solution to change. The liquid will change from colorless to pink, indicating nitrogen leakage or a defect in the flow channel plate. By observing the change in liquid color, the sealing performance of the flow channel plate can be quickly determined. After the test is completed, the circulation pump 3 is started to pump the liquid in the test tank 1 into the reduction tank 2 through the input pipe 14. In the reduction tank 2, carbon dioxide is introduced into the liquid through the air inlet pipe 17. The carbon dioxide will react with the sodium bicarbonate solution to restore the pH value of the liquid and make it change from pink back to colorless. The reduced liquid is recycled through the recovery pipe 18.

[0029] It should be noted that the test solution used is sodium bicarbonate solution, and a pH indicator is added.
