[0027] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0028] When the reaction kettle for formaldehyde preparation starts to be used, the user first rotates the rotating rod 406 in the adjusting member 4. The rotation of the rotating rod 406 drives the slider 405 to move up and down through the reverse thread provided on the outer wall of the rotating rod 406. The slider 405 drives the lever 404 to move up and down. The up and down movement of the lever 404 drives the first adjusting plate 402 and the second adjusting plate 403 to move back and forth through the inclined chutes provided inside the first adjusting plate 402 and the second adjusting plate 403. The first adjusting plate 402 and the second adjusting plate 403 move back and forth to adjust the size of the internal through hole of the exhaust pipe 3, thereby adjusting the exhaust speed of the exhaust pipe 3. The gas inside the reaction kettle 1 passes through the exhaust pipe 3 and the filter layer 504 in the filtering member 5 to filter the gas, filtering out the harmful substances in the gas. After the filtering is completed, rotate the rotating rod 509 downward. The downward rotation of the rotating rod 509 cancels the limit on the second clamping plate 502. Rotate the second clamping plate 502 upward. The second clamping plate 502 drives the second support frame 503 to rotate upward. The second support frame 503 drives the filter layer 504 to rotate upward. Then move the limiting rod 506 forward. The forward movement of the limiting rod 506 cancels the limit on the clamping block 505. Move the filter layer 504 forward. After cleaning the filter layer 504, move the filter layer 504 backward. The filter layer 504 drives the second support frame 503 to move backward. The second support frame 503 drives the clamping block 505 to move backward. The backward movement of the clamping block 505 drives the clamping block 508 to move outward. When the clamping block 505 moves to a suitable position, the spring inside the clamping block 508 and the vertical rod 507 drives the clamping block 508 to reset. The spring provided on the outer wall of the limiting rod 506 drives the limiting rod 506 to reset. The reset of the limiting rod 506 and the clamping block 508 limits the clamping block 505. The clamping block 505 limits and fixes the filter layer 504 through the second support frame 503. Rotate the second clamping plate 502 downward. The second clamping plate 502 drives the filter layer 504 to move downward through the second support frame 503 and is clamped inside the exhaust pipe 3.
