Description

Technical Field

[0001] The utility model relates to the technical field of liquid alarm devices, and particularly relates to a liquid level alarm device for a liquid bath of a copper sheet corrosion test pressure vessel. Background Art

[0002] For different product types, different test conditions can be used. Generally, aviation kerosene is tested in a pressure vessel at 100°C, while other high-vapor-pressure fuels such as natural gasoline are tested at 40°C, and other liquid products can be tested in test tubes at 50°C, 100°C or higher temperatures. The following test temperature and test time conditions are commonly used.

[0003] The Chinese invention patent with the publication number of CN117538512A discloses a copper sheet corrosion test device for aviation fuel oil. This device suspends the test copper sheet in the test barrel by setting a suspension crossbar and a suspension rope, so that the copper sheet does not contact the test barrel, improving the test accuracy. However, this device cannot effectively judge the height of the bath liquid and cannot accurately determine whether the pressure vessel is completely immersed during the test. If too much bath liquid is filled, it is easy to cause waste or overflow, resulting in waste of resources. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Referring to Figures 1 to 5 a liquid level alarm device for a liquid bath of a copper sheet corrosion test pressure vessel shown, which includes a base 1 for submerging the pressure vessel. A plurality of pressure vessels are detachably arranged on the base 1. A floating ball 14 is slidably arranged in the base 1. The floating ball 14 detects the liquid in the base 1 and reports the real-time height of the liquid in the base 1, and gives an alarm when the liquid deviates.

[0018] At the upper end of the base 1, there is a control console 2. On the control console 2, there are a power supply, indicator lights, and switch operation buttons. Inside the base 1, there is a cavity filled with immersion liquid. And multiple groups of pressure vessels are detachably arranged on the base 1. The pressure vessel includes the pressure vessel 7. On the pressure vessel 7, there is a detachable top cover 4. Inside the pressure vessel 7, there is a test tube. Inside the test tube, there are copper sheets and specimens, and the copper sheets are completely immersed in the specimens. On the base 1, there is a bracket 5. On the bracket 5, there is a motor 6. On the output shaft of the motor 6, there is a stirring rod 8. The stirring rod 8 stirs the liquid inside the base 1. Regular stirring maintains the stability of the temperature, concentration, and other important parameters in the bath solution, and can ensure the consistency and controllability of test conditions in the case of long-term tests or multiple samples being tested simultaneously. On the side of the cavity inside the base 1, there are two induction shells 9. Inside the induction shells 9, there are floating balls 14 slidingly arranged. The induction shells 9 detect the height of the floating balls 14. On the side of the base 1, there are a transmitter 13 and a liquid inlet 3. The transmitter 13 is connected to the induction shells 9. The induction shells 9 send signals to the transmitter 13 in real time to determine the position of the floating balls 14. The liquid inlet 3 is connected to the cavity. Bath solution is added into the cavity through the liquid inlet 3. The present utility model further includes a mounting bracket 10. On the mounting bracket 10, there are a receiver 11 and an alarm 12. When the receiver 11 receives a signal, it sends a signal to the alarm 12, and the alarm 12 is driven to sound an alarm to remind the staff to handle it. The position of the induction shell 9 inside the floating ball 14 is controlled by the liquid in the cavity inside the base 1. And the floating ball 14 is made of a material that is heat-resistant, corrosion-resistant, and oil-proof. The heat-resistant, corrosion-resistant, and oil-proof floating ball material usually has a long service life, maintains stable physical and chemical properties in multiple tests, reduces the frequency of replacement and maintenance, and reduces the test cost and human resource input.

[0019] Working principle: During operation, pour 30 mL of a completely clear, water-free suspension or water-free specimen into a clean and dry test tube. Polish the copper sheet. Within 1 minute after completing the copper sheet polishing step, slide the copper sheet into the test tube and immerse it in the specimen. Place the test tube in the pressure vessel 7, then install the top cover 4 on the pressure vessel 7. Place the pressure vessel 7 in the base 1. Place each group of pressure vessels 7 in the liquid, and the liquid in the base 1 is maintained at one hundred degrees Celsius. After placing it in the bath solution for two hours, take out the pressure vessel 7 and soak it in cold water on the bracket 5 for five minutes. Then open the top cover 4 and take out the test tube to observe and check the copper sheet.

[0020] During the soaking process, drive motor 6 is driven, and motor 6 drives stirring rod 8 to rotate. Stirring rod 8 stirs the liquid in the cavity to maintain the stability of the temperature, concentration and other important parameters in the bath solution. The liquid in the cavity drives floating ball 14 to slide in induction housing 9. Floating ball 14 detects the position of induction housing 9. Induction housing 9 transmits the position of floating ball 14 to transmitter 13 in real time for analysis. When transmitter 13 analyzes that the position of floating ball 14 deviates, it indicates that there is a problem with the height of the liquid in the cavity. Transmitter 13 transmits an alarm signal to receiver 11. Receiver 11 transmits a signal to alarm 12, and alarm 12 issues an alarm to remind the staff. When the liquid in the cavity is less, bath solution is added to the cavity through liquid inlet 3.

[0021] The present utility model is not limited to the above specific embodiments. Those skilled in the art in the technical field starting from the above concepts and making various transformations without creative labor all fall within the protection scope of the present utility model.
