The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] Example 1

[0040] A tea leaf air separation exhaust gas filtration device, such as Figure 1-4 As shown, it includes:

[0041] Filter channel 1, wherein a filter element 15 is continuously installed on the inner side of the filter channel 1 by means of a filter element fixing assembly;

[0042] A first mounting groove 13 is provided at the end of the connecting channel 2 away from the filter channel 1, and a second mounting groove 14 is provided at the end of the connecting channel 2 close to the filter channel 1. The two ends of the filter channel 1 are movably installed in the second mounting grooves 14 of the two connecting channels 2.

[0043] First channel 3, the first channel 3 is installed in a first mounting slot 13 of a connecting channel 2;

[0044] The second channel 9 is installed in the first mounting slot 13 of another connecting channel 2;

[0045] A positioning component is installed on filter channel 1 and is used to position the connecting channel 2.

[0046] The positioning component includes:

[0047] Guide sections are provided on both sides of the filter channel 1;

[0048] The support arm is rotatably mounted on the filter channel 1 via a shaft. A positioning groove 16 is provided on the side of the connecting channel 2 near the filter channel 1. The positioning groove 16 is adapted to the end of the support arm. When the end of the support arm is inserted into the positioning groove 16, the support arm is perpendicular to the end face of the connecting channel 2.

[0049] By setting up a connecting channel 2 and other structures, exhaust gas is transported from the first channel 3 through the filter channel 1 to the second channel 9, where it is filtered by the filter element 15. Since the filter channel 1 and the connecting channel 2 are movable, the distance between the two connecting channels 2 can be adjusted. When the two connecting channels 2 retract into the filter channel 1, the filter channel 1 can be easily disassembled, facilitating the replacement of the filter element 15. During installation, after alignment, the connecting channel 2 can be propped up outward by rotating the support arm, so that the first channel 3 and the second channel 9 can be inserted into the first mounting groove 13 of the two connecting channels 2, achieving quick installation and fixation, convenient operation, and improved practicality.

[0050] To ensure stable movement of connecting channel 2; such as Figure 1 As shown, a side bracket 7 is fixed to the side of the filter channel 1, and a slide rod 4 is slidably connected inside the side bracket 7. One end of the slide rod 4 is fixed to the connecting channel 2.

[0051] To facilitate the reset of connection channel 2; such as Figure 1 As shown, a limiting block 6 is detachably mounted on the slide rod 4 via a set screw 8, and the limiting block 6 and the side bracket 7 are connected by a spring 5;

[0052] By setting up structures such as slide bar 4 and limit block 6, the connecting channel 2 can be guided and limited when it moves. At the same time, based on the rebound force of spring 5 and the support arm, the connecting channel 2 can be kept as stable as possible, thus improving reliability.

[0053] To adjust the position of connection channel 2; such as Figure 1 , Figure 4 As shown, the support arm includes:

[0054] The first support arm 21 is rotatably mounted on the filter channel 1 via a shaft;

[0055] The second support arm 20 is slidably mounted on one end of the first support arm 21, and a handle 10 is provided at the top of one end of the second support arm 20; a fixing knob 22 for fixing the first support arm 21 is threadedly connected to the second support arm 20.

[0056] By setting up a support arm, the effective length of the support arm can be adjusted according to needs, thereby adjusting the support position on the connecting channel 2.

[0057] For ease of adjustment; such as Figure 4 As shown, the top of the first support arm 21 is provided with a scale line 23.

[0058] To improve stability; such as Figure 4 As shown, an anti-slip pad 25 is fixed inside the positioning groove 16, and a plurality of hollow rubber columns 24 are provided on the inner arc-shaped surface of the anti-slip pad 25.

[0059] By setting anti-slip pads 25 and hollow rubber columns 24, friction can be increased when the end of the second support arm 20 is engaged, preventing the second support arm 20 from detaching and improving structural stability.

[0060] To facilitate fixing the filter element 15; such as Figure 3 As shown, the filter element fixing assembly includes:

[0061] Mounting frame 11, a first sealing strip 26 is provided on the side of mounting frame 11 near filter element 15;

[0062] Fixing plate 19, fixing plate 19 has an L-shaped structure;

[0063] Screw 27 is fixed to the outer wall of the mounting frame 11 near the fixing plate 19. There is a gap between the filter element 15 and the inner wall of the filter channel 1, and the screw 27 is located in the gap.

[0064] The fixing screw 18 and the fixing plate 19 are installed on the screw barrel 27 by the fixing screw 18, and the filter element 15 is clamped and fixed based on the fixing plate 19 and the mounting frame 11.

[0065] By setting the mounting frame 11 and the fixing plate 19, it is easy to clamp and fix the filter element 15. The mounting frame 11 can improve the sealing of the structure and prevent exhaust gas from escaping from the gap between the filter channel 1 and the filter element 15.
