[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a leak detection container tank, as Figure 1 - Figure 2 shown, which includes a vacuum pumping device and a tank body 6. The vacuum pumping device is used to perform a vacuum pumping operation on the tank body 6. The vacuum pumping device includes a first conduit 1, a second conduit 2, a ball valve 3, a vacuum pressure reducing valve 4, and a vacuum generator 5. One end of the first conduit 1 is connected to the vacuum generator 5, and the other end is connected to the vacuum pressure reducing valve 4. The upper end of the ball valve 3 is connected to the compressed air connecting pipe 31, and the top end of the compressed air connecting pipe 31 is connected to a compressed air source. One end of the second conduit 2 is connected to the vacuum pressure reducing valve 4, and the other end is connected to the tank body 6. The series design of the vacuum generator 5 with the first conduit 1 and the second conduit 2, combined with the flexible opening and closing of the ball valve 3, realizes a fast and stable vacuum pumping process. Compared with traditional vacuum pumps, this design is more compact and portable, easy to operate, does not require additional grease lubrication, and keeps the working environment clean. The addition of the vacuum pressure reducing valve 4 effectively prevents the pressure in the tank body 6 from being too high, ensuring the pressure stability during the vacuum pumping process. Through precise regulation, the preset vacuum degree can be easily achieved, providing a reliable guarantee for subsequent leak detection. The entire vacuum pumping device is tightly connected to the tank body 6 to form a closed and efficient detection system. This integrated design not only improves the portability of the device, but also reduces the connection points, reduces the leakage risk, and enhances the reliability of the detection. This design can easily access the compressed air source, and provide compressed air source for the vacuum generator 5 through the compressed air connecting pipe 31, so that the system can maintain stable performance output in different working environments, meeting the requirements of diverse detection scenarios.

[0023] In this embodiment, the air inlet end of the vacuum generator 5 is connected to the ball valve 3 for accessing the compressed air source, and the air extraction end of the vacuum generator 5 is connected to the first conduit 1. This design ensures that the negative pressure generated by the vacuum generator can be quickly and effectively controlled. When the ball valve 3 is closed, the output of the vacuum generator can be immediately cut off, facilitating the precise control of the vacuum degree in the tank body 6 and improving the sensitivity and accuracy of the detection.

[0024] Specifically, the vacuum pressure reducing valve 4 is installed on the outside of the compressed air connecting pipe 31 through a fixing frame. This design not only stabilizes the position of the pressure reducing valve, but also facilitates operation and maintenance. At the same time, it can effectively adjust the pressure of the compressed air entering the vacuum generator 5 to ensure the stability and safety of the vacuuming process.

[0025] Furthermore, the tank body 6 is a cylindrical structure, with a sealing cover 61 on the top, and two raised ribs 62 on the bottom of the sealing cover 61, which are used to press down the floating milk powder can body, and the height of the ribs 62 is 5-10 cm. The two ribs 62 arranged at the bottom can effectively press down the floating milk powder can body, ensuring that it remains stable during the detection process. The height of the ribs 62 is designed to be 5-10 cm, which not only ensures sufficient downward pressure, but also avoids unnecessary damage to the milk powder can, thereby improving the reliability of the detection and the protection of the milk powder can.

[0026] Furthermore, a pressure gauge 7 is included to measure the pressure value in the tank body 6, and the pressure gauge 7 is fixed to the top of the sealing cover 61 through a bracket 71. The pressure gauge 7 fixedly installed on the top of the sealing cover 61 through the bracket 71 can measure the pressure value in the tank body 6 in real time and accurately. This design enables the operator to intuitively understand the pressure changes during the detection process, facilitates timely adjustment of the detection parameters, and improves the accuracy and operability of the detection.

[0027] Furthermore, a muffler is installed on the compressed air connecting pipe 31 to reduce the noise during the compressed air process. The noise generated during the compressed air process is effectively reduced, providing a more comfortable working environment for the operator. At the same time, it also reduces the interference of the equipment to the surrounding environment during operation and improves the overall performance of the equipment.

[0028] Furthermore, an impurity groove is installed at the bottom of the vacuum generator 5, and the impurity groove is threadedly connected to the bottom end of the vacuum generator 5. It is convenient for regular cleaning and maintenance. This design can effectively collect and remove impurities and particulate matter generated during the vacuuming process, keep the vacuum generator clean and operate efficiently, and extend the service life of the equipment.

[0029] Furthermore, the internal transverse dimension of the tank body 6 is adapted to the height dimension of the 401# milk powder can, so that the 401# milk powder can can be placed horizontally in the tank body 6 for pressure leakage detection; the internal longitudinal dimension of the tank body 6 is adapted to the height dimension of the 502# milk powder can, so that the 502# milk powder can can be immersed in water for leakage detection under the pressure of the ribs 62. This size adaptability design improves the versatility and flexibility of the equipment and meets the leakage detection requirements of milk powder cans of different models.

[0030] When the leak detection container tank of the utility model is used, firstly, the pressure gauge is set to a fixed pressure value according to the detection requirements. This value is usually determined according to the specifications and detection standards of the milk powder tank. Ensure that the vacuum generator, vacuum pressure reducing valve, ball valve and other equipment are in normal working condition. Fill the tank body to a specific water level, which is usually determined according to the size of the milk powder tank and the detection requirements.

[0031] Place the milk powder can to be tested (such as 401# or 502# milk powder can) into the tank body. For milk powder cans of different sizes, the appropriate placement method can be selected according to their height dimensions. For example, 401# milk powder cans can be placed horizontally, while 502# milk powder cans can be placed vertically, and both are immersed in water under the pressure of the ribs. Open the ball valve to allow compressed air to enter the vacuum generator. The vacuum generator starts working, causing the first conduit to generate negative pressure, extracting the air in the tank body and forming negative pressure in the tank. When the pressure value displayed on the pressure gauge reaches the set pressure value, close the ball valve to maintain the negative pressure state in the container tank.

[0032] After maintaining the negative pressure for a period of time, observe whether there are continuous bubbles at the weld of the milk powder can. The generation of bubbles usually means that there is a leak in the milk powder can. If there are no bubbles, it proves that the sealing performance of the milk powder can is good and there is no leakage. After the test is completed, the relevant valve can be opened to restore the pressure in the tank to normal. Record the test results, including the model of the milk powder can, the test time, the pressure value, and whether there is leakage.

[0033] Finally, it should be noted that the vacuum generator 5 and the like in this embodiment, the electronic components in the above-mentioned parts are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively, and the specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
