Description

Technical Field

[0001] This utility model relates to the field of helium mass spectrometry leak detection technology, specifically a helium mass spectrometry leak detection device with a self-rotating device. Background Technology

[0002] Aseptic raw material packaging systems typically use aluminum drums with volumes ranging from 10 to 100 liters. PP drums and large-format glass bottles are also commonly used in aseptic drug production to hold intermediate liquids. These aseptic solids or liquids may be contaminated by microorganisms during storage, or the packaging system itself may be poorly sealed, leading to loss or entry of solids or liquids, thus posing safety and quality risks. Therefore, the sealing performance of these packaging systems needs to be tested.

[0003] Based on the above, the inventors have discovered the following problems: Currently, the commonly used helium mass spectrometry leak detection method is used to test the sealing of large-scale pharmaceutical packaging systems. The distance between the suction gun and the packaging system and the scanning speed will affect the sensitivity setting of the detection, resulting in false negatives. At present, the suction gun is scanned around the sample manually, which has poor controllability.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a helium mass spectrometer leak detection device with a self-spinning device, in order to achieve a more practical purpose. Summary of the Invention

[0005] The purpose of this invention is to provide a helium mass spectrometry leak detection device with a self-rotating device, in order to solve the problem mentioned in the background art that the commonly used helium mass spectrometry leak detection method for large-scale pharmaceutical packaging system sealing detection has the problem that the distance between the suction gun and the packaging system and the scanning speed will affect the sensitivity setting of the detection and cause false negatives. Currently, the suction gun is scanned around the sample manually, which has poor controllability.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A helium mass spectrometer leak detection device with a self-rotating mechanism includes an operating table. A vacuum pump is installed at the bottom of the operating table, and a helium mass spectrometer leak detection main unit is installed at the top of the operating table. One end of the vacuum pump is connected to a suction pipe, and one end of the suction pipe is connected to the output end of the helium mass spectrometer leak detection main unit. A connection port is installed at the top input end of the helium mass spectrometer leak detection main unit. A first base is provided on one side of the operating table, and a slide rail is installed at the top of the first base. A damping slider is slidably connected to the outside of the slide rail. A suction gun is installed on one side of the damping slider, and a connecting pipe is installed at one end of the suction gun. A connecting buckle is installed at one end of the connecting pipe, and one end of the connecting buckle engages with the top of the connection port. A second base is provided on one side of the first base, and a rotating platform is installed at the top of the second base. A test chamber is located at the top of the rotating platform.

[0007] Furthermore, an outlet valve and an inlet valve are installed at the top of the test barrel. A helium cylinder is provided on one side of the test barrel. A helium pipe is installed at the output end of the helium cylinder. One end of the helium pipe is connected to one end of the inlet valve.

[0008] The beneficial effect of adopting the above-mentioned further solution is that, through the setting of the exhaust valve, the inlet valve, the helium cylinder, and the helium pipeline, the inlet valve is connected to the helium pipeline output from the helium cylinder to fill the barrel with helium. If there is a leak in the barrel, the helium will overflow. The exhaust valve can be used to discharge excess gas in the barrel or to discharge residual helium after testing.

[0009] Furthermore, a filter screen is installed at the other end of the suction gun.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, by installing a filter screen at the other end of the suction gun, impurities and particles in the suction gas can be filtered out, preventing these impurities from entering the helium mass spectrometer leak detection host.

[0011] Furthermore, a shelf is installed inside the operating table, and the bottom end of the vacuum pump is fixedly connected to the top end of the shelf.

[0012] The advantage of adopting the above-mentioned further solution is that by fixing the bottom end of the vacuum pump to the top end of the shelf, a stable mounting surface is provided for the vacuum pump.

[0013] Furthermore, six spring plates are installed on the outer side of the top of the rotating platform, and one side of each spring plate is in contact with the outer side of the barrel to be tested.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by installing six spring plates on the outer side of the top of the rotating platform, the test barrel can be fixed, while avoiding hard damage to the surface of the barrel. It is suitable for test barrels of different shapes and materials.

[0015] Furthermore, a scale is installed on one side of the slide rail.

[0016] The advantage of adopting the above-mentioned further solution is that, by installing a scale on one side of the slide rail, the position of the damping slider and the suction gun on the slide rail can be displayed intuitively.

[0017] Furthermore, a display screen is installed on one side of the helium mass spectrometer leak detection host.

[0018] The advantage of adopting the above-mentioned further solution is that a display screen is installed on one side of the helium mass spectrometer leak detection host, which can display detection data, detection status and other information in real time.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This helium mass spectrometry leak detection device with a self-rotating device is connected to the helium mass spectrometry leak detection host via a vacuum pump, enabling the gas drawn in by the suction gun to enter the helium mass spectrometry leak detection host, thereby realizing helium detection. The slide rail on the first base cooperates with the damping slider to flexibly adjust the position of the suction gun, facilitating the detection of leak points at different locations. The suction gun is connected to the helium mass spectrometry leak detection host via connecting pipes and connecting buckles to ensure stable gas transmission. The rotating platform on the second base can drive the test barrel to rotate, so that all parts of the barrel can be detected, avoiding detection blind spots and improving detection comprehensiveness and efficiency. Through the setting of an outlet valve, an inlet valve, a helium cylinder, and a helium pipeline, the inlet valve is connected to the helium pipeline output from the helium cylinder to fill the barrel with helium. If there is a leak in the barrel, the helium will overflow, and the outlet valve can be used to discharge the gas from the barrel. Excess gas or residual helium gas is discharged after detection. A filter screen is installed at the other end of the suction gun to filter impurities and particles in the sucked-in gas, preventing these impurities from entering the helium mass spectrometer leak detection host. The bottom of the vacuum pump is fixedly connected to the top of the shelf, providing a stable mounting surface for the vacuum pump.
