The front side of the air intake conveying pipe 5 is rotatably connected with a cleaning door 6 by a hinge. The bottom near the inner wall of the condensation recovery box 3 is fixedly connected with an intercepting net plate 7. The middle near the inner wall of the air intake treatment box 4 is fixedly connected with a water filter grid 8. The surface of the inner wall of the air intake treatment box 4 is fixedly installed with a waterproof fan 9, and the waterproof fan 9 is located directly below the air intake conveying pipe 5. The side of the inner wall of the air intake treatment box 4 is fixedly installed with a driving motor 10 through a fixed frame, and the driving motor 10 is located in the middle of the fixed frame. The output end of the driving motor 10 is fixedly connected with a rotating disk 11. The bottom of the rotating disk 11 is rotatably connected with an adjusting rod 12 through a pin shaft. The bottom near the inner wall of the air intake treatment box 4 is fixedly connected with a limiting groove plate 13. The inner wall of the limiting groove plate 13 and the surface of the adjusting rod 12 are slidably connected. The bottom of the adjusting rod 12 is fixedly connected with a knocking plate 14. The top near the inner wall of the condensation recovery box 3 is fixedly connected with a condensed water bead net plate 15, and the top of the condensed water bead net plate 15 abuts against the bottom of the knocking plate 14. The right side of the condensation recovery box 3 is fixedly connected with an air outlet pipe 16 with a water filter net and a control valve pipe 17.

[0027] Specifically, as Figures 1 - 5 shown, an exhaust fan 18 is fixedly installed on the inner wall of the air intake conveying pipe 5. The bottom near the inner wall of the air intake conveying pipe 5 is fixedly installed with a semi-circular arched net 19. The number of the semi-circular arched nets 19 is at least two, and at least two semi-circular arched nets 19 are evenly distributed at the upper and lower parts of the air intake conveying pipe 5. The inner wall of the limiting groove plate 13 is rotatably connected with a guide wheel 20 through a bearing. The surface of the guide wheel 20 and the surface of the adjusting rod 12 are in rolling connection. Through the operation of the exhaust fan 18 in the air intake conveying pipe 5, the generated water mist can be discharged into the interior of the air intake treatment box 4.

[0030] The working principle of the present utility model: When in use, the original paper drying box 1 conducts the drying treatment of the original paper. During the drying process, water mist will be generated on the original paper. Through the operation of the exhaust fan 18 in the air intake conveying pipe 5, the generated water mist can be discharged and guided into the interior of the air intake treatment box 4. The inhaled impurities will first pass through the filter screen in the air intake conveying pipe 5 for filtration, and the semi-circular arched net 19 can intercept and block the impurities in the subsequent discharged water mist. The semi-circular arc surface can make the intercepted impurities stay above the outer circle. At the same time, the waterproof fan 9 can guide the water mist above to the condensation recovery box 3 for condensation treatment. The operation of the waterproof fan 9 can conduct air exchange work through the water filter grid frame 8. At the same time, the operation of the driving motor 10 can drive the rotating disk 11 to rotate. The rotation of the rotating disk 11 can drive the adjusting rod 12 to move up and down. Through the pin sleeve at the center of the adjusting rod 12, rotational commutation adjustment can be carried out, and the repeated up and down movement of the knocking plate 14 can be completed, so that the knocking plate 14 can knock the condensed water bead net plate 15 below, causing the water droplets condensed on the condensed water bead net plate 15 to fall into the condensation recovery box 3, and the water droplets and water beads are gathered and stored inside the condensation recovery box 3. The air outlet pipe 16 can discharge the exhausted gas after condensation collection. When the water level sensor 24 in the condensation recovery box 3 can sense the water level inside it, after the expected collection of steam and water mist accumulates, it is discharged through the control valve pipe 17, ensuring that the exhausted gas with steam in the original paper drying box 1 is guided, condensed, gathered, and stored for subsequent discharge.
