[0027] Example

[0028] like Figures 1 to 4 An air filter device for a mass spectrometer shown in the figure comprises a housing 1, a partition plate 3 arranged on the vertical inner wall of the housing 1, and a mass spectrometer body 12 arranged inside the housing 1;

[0029] In order to facilitate the automatic cleaning and collection of dust and impurities on the surface of the filter plate 9, a limit frame 13 is fixed at the top of the partition 3, and the partition 3 is communicated with the limit frame 13. Four square columns 5 are fixed on the outer periphery of the limit frame 13, and a top cover 19 is fixed on the top of the four square columns 5. The top of the top cover 19 is provided with a slot 17 that completely penetrates the top cover 19. A plurality of filter plates 9 for isolating dust and impurities during the air filtration process of the mass spectrometer are installed between the limit frame 13 and the top cover 19, and the slot 17 is close to the outer wall of the filter plate 9. A first telescopic rod 8 is installed at the top of the top cover 19. Through the extension and retraction of the first telescopic rod 8 set at the top of the top cover 19, the four scrapers 6 on the side of the connecting plate 7 are driven to move up and down and plug into the slot 17 at the top of the top cover 19, so that the scraper 6 can fit on the outer wall of the filter plate 9 and move up and down, so that the dust and impurities on the outer wall of the filter plate 9 fall into the collection box 4 set at the top of the partition 3.

[0030] By pulling out the fixing nails 20 arranged on the side of the box body 1, the dust and impurities on the surface of the filter plate 9 are automatically cleaned and collected, saving manpower and improving the use efficiency. A cross-shaped connecting plate 7 is fixed to one side of the moving part of the first telescopic rod 8, and four scrapers 6 are fixed to the side of the connecting plate 7, and the four scrapers 6 are respectively fitted into the four slots 17.

[0031] Two collecting boxes 4 that fit together are tightly attached to the top of the partition 3. A fixing nail 20 extending to the inner wall of the collecting box 4 is threadedly connected to the side of the box body 1. Four mounting strips 15 are fixed to the inner wall of the limit frame 13. A mounting plate 16 is fixed between the four mounting strips 15. A fan 18 for ventilation of the mass spectrometer body 12 is installed on the top of the mounting plate 16. A connecting frame 14 is fixed to the inner wall of the box body 1. A second telescopic rod 10 is installed on the inner wall of the limit frame 13. An extrusion plate 11 that fits the mass spectrometer body 12 is fixed to one side of the moving part of the second telescopic rod 10. The extrusion plate 11 is driven to move by the limit frame 14 arranged on the inner wall of the box body 1 and the second telescopic rod 10 arranged on the inner wall of the limit frame 14, so as to facilitate the fixation of the mass spectrometer body 12.

[0032] The fan 18 arranged at the top of the mounting plate 16 inhales air, so that the air enters the box 1 through the filtration of the filter plate 9. The filter plate 9 can be an activated carbon filter plate, or activated carbon filtration, depending on the specific situation, is a process of water treatment using activated carbon as filter material. Activated carbon is a black solid substance with carbon as a skeleton structure that has developed pores through gasification (carbonization, activation). Its developed pores give it a large specific surface area, with a surface area of ​​500 to 1700 square meters per gram of material, thus having good adsorption characteristics. The specific gravity of activated carbon is 1.9 to 2.1.

[0033] The mass spectrometer body 12 is also called a mass spectrometer. An instrument for separating and detecting different isotopes. That is, a type of instrument that separates and detects the composition of substances according to the mass difference of atoms, molecules or molecular fragments of substances based on the principle that charged particles can be deflected in an electromagnetic field. Mass spectrometers are divided into isotope mass spectrometers, inorganic mass spectrometers and organic mass spectrometers according to their application range. They are divided into high-resolution, medium-resolution and low-resolution mass spectrometers according to their resolution ability; and they are divided into static instruments and dynamic instruments according to their working principles.

[0034] The first telescopic rod 8, the second telescopic rod 10, the fan 18 and the mass spectrometer body 12 are all conventional instruments. The working principle, size and model are irrelevant to the function of the present application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0035] How it works

[0036] During use of the air filtering device for the mass spectrometer, the first telescopic rod 8 arranged at the top of the top cover 19 is extended and retracted, driving the connecting plate 7 to move up and down, thereby driving the scraper 6 to move synchronously, so that the scraper 6 is inserted into the slot 17 arranged at the top of the top cover 19, and moves up and down in contact with the filter plate 9, and the dust and impurities arranged on the surface of the filter plate 9 fall into the collection box 4 at the upper end of the partition 3, and the dust and impurities are cleaned and collected by pulling out the fixing nails 20 arranged on the side of the box body 1.
