Description

Technical Field

[0001] This utility model relates to a mass spectrometer filter and a mass spectrometer. Background Technology

[0002] Currently, there is a technological gap in the filtration of harmful gases and dust generated during the lithium-ion battery leak detection process. When using mass spectrometry to detect leaking lithium-ion batteries, the battery needs to be placed in a vacuum environment, and the electrolyte is extracted from the leak point and fed into the mass spectrometer for detection. During this process, harmful substances in the electrolyte turn into gaseous states in the vacuum environment and are also drawn into the instrument, causing damage. However, there are currently no relevant filters for lithium-ion battery leak detection, resulting in a lack of protection for the equipment. Utility Model Content

[0003] The main objective of this invention is to provide a mass spectrometer filter and a mass spectrometer, aiming to solve the aforementioned technical problems.

[0004] To achieve the above objectives, the present invention proposes a mass spectrometer filter comprising a housing component and a dust filter. The housing component has an airflow channel that extends through the airflow channel along an axial direction. The two ends of the airflow channel are an air inlet and an air outlet, respectively. The housing component includes a plurality of packing blocks disposed on the airflow channel. The dust filter is disposed at the air inlet and / or the air outlet.

[0006] In one embodiment, the support plate includes a first guide group and a second guide group, which are sequentially arranged within the airflow channel to form a bent airflow channel.

[0007] In one embodiment, the first guide assembly includes two first plates, and the filler block is connected between the first plates to form a first gap between the first plates and the inner wall surface of the inner frame.

[0008] In one embodiment, the second guide assembly includes two second plates, and the filler block is connected between the second plates and the inner wall of the inner frame to form a second gap between the two second plates.

[0009] In one embodiment, both the air inlet and the outlet are provided with flange connections.

[0024] This invention provides a mass spectrometer filter.

[0025] like Figure 1-2 As shown, the mass spectrometer filter provided in this embodiment of the present invention includes a housing component 10 and a dust filter. The housing component 10 has an airflow channel that extends through the airflow channel along the axial direction. The two ends of the airflow channel are an air inlet end 11 and an air outlet end 12, respectively. The housing component 10 includes a plurality of packing blocks 20 disposed on the airflow channel. The dust filter is disposed at the air inlet end 11 and / or the air outlet end 12.

[0026] In this embodiment, the gas is in full contact with the packing block 20 in the filter. The harmful gas undergoes physical and chemical adsorption with the packing, and no new gas is generated. Most of the target gas is transmitted by power (e.g., a vacuum pump) through the airflow channel to the detection instrument. Since most of the gas reaching the instrument is the target gas and a small amount of other impurity gas, the gas components that may damage the instrument have been filtered out by the packing block 20, thereby protecting the instrument.

[0027] Specifically, the housing component 10 includes an outer shell 13 and an inner frame 14 disposed inside the outer shell 13. The inner frame 14 is provided with multiple support plates, and the filler block 20 is mounted on the support plates. Each support plate includes a first flow guide group 15 and a second flow guide group 16, which are sequentially arranged within the airflow channel to form a bent airflow channel. Figure 2 As shown, in this embodiment, the airflow channel adopts a bent shape, which is suitable for use when the particles of the packing block 20 are small, in close contact with each other, and difficult for gas to flow through. This allows the gas to flow smoothly while still making full contact with the gas, thus meeting the adsorption and filtration requirements.

[0028] Specifically, the first flow guiding group 15 includes two first plates 151, and the packing block 20 is connected between the first plates 151 to form a first gap 152 between the first plates 151 and the inner wall surface of the inner frame 14. The second flow guiding group 16 includes two second plates 161, and the packing block 20 is connected between the second plates 161 and the inner wall surface of the inner frame 14 to form a second gap 162 between the two second plates 161. Therefore, gas enters from the inlet end 11 and flows through the first gap 152 and the second gap 162 in sequence. At this time, the gas that can be absorbed by the packing block 20 will be absorbed by the packing block 20. The material of the packing block 20 can be calcium lime, soda lime, or molecular sieve. In other embodiments, the packing block 20 can also be made of other materials that can absorb gases, which will not be described in detail here.

[0029] Please refer to Figure 3 In another embodiment, the packing block 20 can be directly installed on the airflow channel. This is because in this embodiment, the packing block itself has larger particles and a smaller contact area with each other, but a larger contact area with the gas and a larger internal space, which allows the gas to pass through smoothly and has less impact on the detection results.

[0030] In the above embodiments, the material of the outer shell 13 is not limited, as long as it is sturdy, firm, and meets the sealing requirements. Depending on the usage conditions, stainless steel or all-aluminum materials can be selected. The size of the shell is not limited, and the size is designed according to the usage requirements. While meeting the requirements for loading the necessary packing material, the equipment load should be minimized, while ensuring sufficient contact between the gas and the packing material, and minimizing excess space.

[0031] Both ends of the dust filter can be composed of sieve plates with a hole diameter of 1-2mm fixed by snap rings, which can block and fix the packing, so that the packing will not enter the pipeline and cause blockage. In addition, both the air inlet 11 and the outlet are provided with flange connection ports. The flange connection port can be of type KF16, and the connection and sealing are achieved by KF16 fluororubber sealing rings.

[0032] Furthermore, this utility model also provides a mass spectrometer, which includes the mass spectrometer filter described above. The above descriptions are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of this utility model's specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
