A mounting handle 13 is installed on the outer wall of the smoke tube 11, so that the staff can easily lift and move the smoke tube 11.

[0031] In this embodiment, a mounting base 2 is installed on the outer wall of the device body 1 for receiving and supporting the smoke tube 11, and an L-shaped sliding groove 21 is opened on the inner wall of the mounting base 2 to provide guidance and support for the smoke tube 11, which is conducive to guiding the fixed block 12 to move to the predetermined installation position. A hemispherical limit block 23 is installed on the inner wall of the sliding groove 21, which is conducive to ensuring that the fixed block 12 will not continue to slide or fall off after being installed in place, and will not affect the removal of the fixed block 12 under the action of the staff;

[0032] In the following example, a lifting block 22 is rotatably installed on the inner wall of the sliding groove 21. When the smoke dust tube 11 is not installed, the lifting block 22 is designed to be inclined. The inclined lifting block 22 provides a convenient entrance for the installation of the smoke dust tube 11, making it easier for the smoke dust tube 11 to enter the sliding groove 21. After the smoke dust tube 11 is installed, the outer wall of the lifting block 22 and the inner wall of the sliding groove 21 are located in the same plane, providing a solid support surface for the smoke dust tube 11. The outer wall of the lifting block 22 is installed with a support ring 31 made of hard material to ensure its stability and durability, and the outer wall of the support ring 31 is installed with a sealing gasket 3 to fill the tiny gap between the smoke dust tube 11 and the device body 1 to prevent smoke dust leakage.

[0033] See also Figure 1 - Figure 6 Multiple sets of fixing blocks 12 are installed at equal angles on the outer wall of the smoke tube 11, and the outer wall of the fixing block 12 is designed in an arc shape. The evenly distributed fixing blocks 12 are conducive to firmly fixing the smoke tube 11 and ensuring the stability of the smoke tube 11. The arc shape design makes the fixing blocks smoother during installation and disassembly.

[0034] See also Figure 1 - Figure 7 , multiple sets of sliding grooves 21 are opened at equal angles on the inner wall of the mounting base 2, and the sliding grooves 21 are L-shaped. The fixed block 12 corresponds to the sliding grooves 21, providing uniform support. The L-shaped sliding grooves 21 provide a clear guide path for the fixed block 12. The team members can easily align the fixed block 12 with the straight part of the sliding groove 21, and then move and adjust it along the direction of the sliding groove 21 until it reaches the predetermined installation position.

[0035] See also Figure 1 - Figure 7 The limit block 23 is hemispherical in design, and a support ring 31 is rotatably installed at the end of the lifting block 22 close to the opening of the sliding groove 21. The hemispherical limit block 23 is conducive to limiting the position of the fixed block 12 without affecting the movement of the fixed block 12, thereby ensuring the convenience of installation and disassembly of the smoke tube 11.

[0036] See also Figure 1 - Figure 7 When the smoke dust tube 11 is not installed, the lifting block 22 is designed to be inclined, and after the smoke dust tube 11 is installed, the outer wall of the lifting block 22 and the inner wall of the sliding groove 21 are located in the same plane. The inclined lifting block 22 provides a convenient entrance for the installation of the smoke dust tube 11, making it easier for the smoke dust tube 11 to enter the sliding groove 21, simplifying the installation process. The flushness of the lifting block 22 with the inner wall of the sliding groove 21 ensures the stability of the smoke dust tube 11 after installation. The lifting block 22 provides a solid support surface for the smoke dust tube 11 to prevent it from shaking or falling off during use.

[0037] See also Figure 1 - Figure 7 The support ring 31 is made of hard material, and a sealing gasket 3 is installed on the outer wall of the support ring 31 close to the smoke pipe 11, which is beneficial for the support ring 31 to provide stable support for the sealing gasket 3, ensuring that the support ring 31 maintains its shape and function during long-term use, is not easily damaged, and enhances the sealing of the entire system.

[0038] The working principle of the present invention is as follows: when it is necessary to install the smoke dust absorption and filtering device for use in environmental protection equipment, the worker first uses the installation handle 13 to lift the smoke dust pipe 11 close to the mounting seat 2 installed on the outer wall of the device body 1, and then aligns the fixing block 12 installed on the outer wall of the smoke dust pipe 11 with the sliding groove 21 opened on the inner wall of the mounting seat 2, and then moves the smoke dust pipe 11 so that the fixing block 12 moves along the sliding groove 21. When the fixing block 12 moves to the predetermined installation position in the sliding groove 21, it will be limited by the limit block 23 to ensure that the smoke dust pipe 11 does not It will move at will. When the fixed block 12 enters the sliding groove 21, it will squeeze the lifting block 22, causing the tilted lifting block 22 to rotate. The lever principle is used to generate an upward force to drive the support ring 31 installed at the end of the lifting block 22 to move upward. The support ring 31 made of hard material will firmly support the sealing gasket 3, so that the sealing gasket 3 is more closely attached to the outer wall of the smoke pipe 11, ensuring the sealing of the installation and effectively preventing smoke from leaking out of the device, thereby ensuring the efficient operation of the smoke absorption and filtering device and making positive contributions to environmental protection.
