One end of the limiting block 11 close to the sliding piece 9 is fixedly connected to the sliding piece 9. An opening groove 12 is opened at the top end of the regulating housing 5. A pull rod 13 is slidably connected to the inner cavity of the opening groove 12. One end of the pull rod 13 close to the sliding piece 9 is fixedly connected to the sliding piece 9. When the staff needs to disassemble, replace or clean the filter plate 3, the staff pulls the pull rod 13, so that the surface of the pull rod 13 slides in the inner diameter of the opening groove 12. At the same time, the pull rod 13 drives the sliding piece 9 to displace, so that the surface of the sliding piece 9 drives the limiting block 11 to gradually disengage from the inner cavity of the limiting groove 10. Subsequently, the staff pulls the pull rod 13 to drive the inner cavity of the sliding piece 9 to slide on the surface of the fixed column 8, and at the same time compresses the first spring 14 to store energy, so that the surface of the connecting block 7 slides in the inner cavity of the regulating housing 5, and at the same time compresses the second spring 17 to store energy. As the fixed column 8 displaces, the surface of the fixed column 8 drives the guiding block 16 to slide in the inner cavity of the guiding groove 15, and at the same time makes the sliding piece 9 and the limiting block 11 disengage from the inner cavity of the limiting housing 6. At this time, the filter plate 3 will be unconstrained. The staff pulls up the filter plate handle 4 to drive the surface of the filter plate 3 to gradually disengage from the inner cavity of the analyzer body 1. Through the setting of the above structure, it is convenient for the staff to disassemble, replace or clean the filter plate 3, prevent the filter holes of the filter plate 3 from being blocked after long-term use, resulting in a reduction in the filtration effect of the flue gas analyzer, and make it unable to achieve the effect of efficient filtration.

[0027] Referring to Figure 4 As shown in the figure, in this embodiment: First springs 14 are fixedly connected to both sides of the connecting block 7. One end of the first spring 14 close to the sliding piece 9 is fixedly connected to the sliding piece 9. The staff pulls the pull rod 13 to drive the inner cavity of the sliding piece 9 to slide on the surface of the fixed column 8, and at the same time compresses the first spring 14 to store energy. Through the setting of the first spring 14, the rebounding force of the first spring 14 continuously pushes the sliding piece 9 to reset, so that the surface of the sliding piece 9 drives the limiting block 11 to be clamped and limited with the inner cavity of the limiting groove 10.

[0028] Referring to Figure 4As shown in the figure, in this embodiment: a guiding groove 15 is formed inside the adjusting housing 5, and a guiding block 16 is slidably connected to the inner cavity of the guiding groove 15. One end of the guiding block 16 close to the fixed column 8 is fixedly connected to the fixed column 8.

The staff member pulls the pull rod 13, driving the connecting block 7 to displace, and at the same time compressing the second spring 17 to store energy. Through the setting of the second spring 17, the rebounding force of the second spring 17 continuously pushes the connecting block 7 to reset, thereby improving the coordination between structures.

[0030] Referring to Figure 5 and Figure 6 As shown in the figure, in this embodiment: a directional groove 18 is formed inside the analyzer body 1, and a directional block 19 is slidably connected to the inner cavity of the directional groove 18. One end of the directional block 19 close to the filter plate 3 is fixedly connected to the filter plate 3. The staff member pulls the filter plate handle 4, causing the surface of the filter plate 3 to gradually separate from the inner cavity of the analyzer body 1. As the filter plate 3 displaces, the filter plate 3 drives the surface of the directional block 19 to slide in the inner cavity of the directional groove 18. Through the setting of the above structure, when the filter plate 3 displaces, it maintains a directional displacement, preventing the filter plate 3 from shifting and affecting the filtering effect of the filter plate.

[0031] Referring to Figure 1 、 Figure 3 、 Figure 7 and Figure 8 As shown in the figure, in this embodiment: an installation cover 20 is installed at one end of the analyzer body 1. An air inlet groove 21 is formed on the surface of the installation cover 20. A limit bolt 22 is threadedly connected inside the installation cover 20. A iron powder collection box 23 is slidably connected inside the installation cover 20. A U-shaped pull block 24 is fixedly connected to the surface of the iron powder collection box 23. As the filter plate 3 filters, the iron filings and some dust particles contained in the flue gas are blocked by the filter plate 3 and fall into the inner cavity of the iron powder collection box 23 under the action of gravity. When the staff member needs to collect and process the iron filings and dust uniformly, the staff member pulls the U-shaped pull block 24, causing the surface of the iron powder collection box 23 to gradually separate from the inner cavity of the installation cover 20. As the iron powder collection box 23 displaces, the iron powder collection box 23 drives the surface of the sliding rod 26 to slide in the inner cavity of the sliding groove 25. Through the setting of the above structure, it is convenient for the staff member to collect and process the filtered and settled iron filings and dust uniformly.

[0032] Refer to Figure 8 As shown, in this embodiment: a chute 25 is provided inside the installation cover 20. A slide bar 26 is slidably connected to the inner cavity of the chute 25. One end of the slide bar 26 close to the iron powder collection box 23 is fixedly connected to the iron powder collection box 23. The staff pulls the U-shaped pull block 24, so that the surface of the U-shaped pull block 24 drives the iron powder collection box 23 to gradually separate from the inner cavity of the installation cover 20, and at the same time drives the surface of the slide bar 26 to slide in the inner cavity of the chute 25. Through the setting of the above structure, when the iron powder collection box 23 is displaced, it maintains a directional displacement, preventing the iron powder collection box 23 from shaking and affecting the collection and treatment of dust and iron filings in the inner cavity.

[0033] Working principle: When the staff needs to disassemble, replace or clean the filter plate 3, the staff pulls the pull rod 13, so that the surface of the pull rod 13 slides in the inner diameter of the opening groove 12. At the same time, the pull rod 13 drives the sliding piece 9 to displace, so that the surface of the sliding piece 9 drives the limiting block 11 to gradually separate from the inner cavity of the limiting groove 10. Subsequently, the staff pulls the pull rod 13, driving the inner cavity of the sliding piece 9 to slide on the surface of the fixed column 8, and at the same time compressing the first spring 14 to store energy, so that the surface of the connecting block 7 slides in the inner cavity of the adjusting housing 5, and at the same time compressing the second spring 17 to store energy. As the fixed column 8 displaces, the fixed column 8 drives the surface of the guiding block 16 to slide in the inner cavity of the guiding groove 15, and at the same time makes the sliding piece 9 and the limiting block 11 separate from the inner cavity of the limiting housing 6. At this time, the filter plate 3 will be unconstrained. The staff pulls up the filter plate handle 4, driving the surface of the filter plate 3 to gradually separate from the inner cavity of the analyzer body 1. Through the setting of the above structure, it is convenient for the staff to disassemble, replace or clean the filter plate 3, preventing the filter holes of the filter plate 3 from being blocked after long-term use, resulting in a reduction in the filtering effect of the flue gas analyzer and making it unable to achieve an efficient filtering effect. As the filter plate 3 filters, iron filings and some dust particles contained in the flue gas are blocked by the filter plate 3 and fall into the inner cavity of the iron powder collection box 23 under the action of gravity. When the staff needs to collect and process the iron filings and dust uniformly, the staff pulls the U-shaped pull block 24, so that the surface of the U-shaped pull block 24 drives the iron powder collection box 23 to gradually separate from the inner cavity of the installation cover 20. As the iron powder collection box 23 displaces, the iron powder collection box 23 drives the surface of the slide bar 26 to slide in the inner cavity of the chute 25. Through the setting of the above structure, it is convenient for the staff to uniformly collect and process the iron filings and dust that have settled by filtration.
