Detailed implementation manners

[0020] Now, with reference to the accompanying drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] Refer to Figure 1 And Figure 2As shown in the figure, the present utility model provides a technical solution: a drying device for a paper machine, including a drying chamber 1. A control cabinet 2 is fixedly connected to the left side of the drying chamber 1. A number of tension rollers 3 are fixedly connected inside the drying chamber 1. The drying device of the paper machine further includes a heating device 4 installed at the bottom inside the drying chamber 1. A number of ventilation holes 5 are opened at the top of the drying chamber 1. A sealing cover 6 is fixedly connected to the top of the ventilation hole 5. A collecting dish 7 is installed at the bottom of the sealing cover 6. A limiting mechanism is installed at the bottom of the sealing cover 6 for fixing the position of the collecting dish 7. The user controls the temperature of the heating device 4 through the control cabinet 2 to dry the paper entering the inside of the drying chamber 1. The paper winds around the tension rollers 3 inside the drying chamber 1 to increase the tension, preventing the paper from sagging too close to the heating device 4 and causing combustion. The water vapor generated by drying the paper enters the inside of the sealing cover 6 through the ventilation holes 5 and is discharged. During the process of discharging the water vapor, part of the water vapor liquefies inside the sealing cover 6 and drips downward. The collecting dish 7 below the sealing cover 6 collects the liquefied water droplets to prevent the water droplets from wetting the paper below again.

[0022] Referring to Figure 4 With Figure 5 As shown in the figure, in this embodiment: The limiting mechanism includes an annular connecting plate 8 fixedly connected to the bottom of the sealing cover 6. Three L-shaped plates 9 are fixedly connected to the bottom of the annular connecting plate 8. Three limiting plates 10 are fixedly connected to the top of the collecting dish 7. The user rotates the collecting dish 7 to disengage the limiting plate 10 from the inside of the L-shaped plate 9, releasing the limit on the collecting dish 7, facilitating the user to remove the collecting dish 7 to handle the water collected inside the collecting dish 7 and preventing the water inside the collecting dish 7 from overflowing.

[0023] Referring to Figure 5 As shown in the figure, in this embodiment: A thrust spring 11 is fixedly connected to the top of the limiting plate 10. The top of the thrust spring 11 is fixedly connected to a top plate 12. The user places the collecting dish 7 below the sealing cover 6, aligns the limiting plate 10 on the collecting dish 7 with the notch of the collecting dish 7, rotates the collecting dish 7, rotates the limiting plate 10 into the inside of the L-shaped plate 9 to limit the collecting dish 7. At the same time, the thrust spring 11 at the bottom of the limiting plate 10 pushes the top plate 12 upward, increasing the friction between the top plate 12 and the bottom of the sealing cover 6, making the fixation of the collecting dish 7 more stable.

[0024] Referring to Figure 5As shown, in this embodiment: the bottom of the limiting plate 10 is fixedly connected with an anti-skid pad 13, and the bottom of the anti-skid pad 13 fits with the bottom of the inside of the L-shaped plate 9. The user pushes the collecting dish 7 upward to move the limiting plate 10 upward, and the anti-skid pad 13 at the bottom of the limiting plate 10 is separated from the bottom end of the inside of the L-shaped plate 9. The collecting dish 7 is rotated to make the limiting plate 10 disengage from the inside of the L-shaped plate 9, and the limiting of the collecting dish 7 is released. After pouring out the water collected in the collecting dish 7, the limiting plate 10 is aligned with the notch of the L-shaped plate 9, and the collecting dish 7 is pushed upward to compress the thrust spring 11, so that the distance between the limiting plate 10 and the top plate 12 is less than the notch diameter of the L-shaped plate 9. The collecting dish 7 is rotated, and the limiting plate 10 is rotated to the inside of the L-shaped plate 9 and then released. Under the thrust of the thrust spring 11, the bottom of the anti-skid pad 13 fits with the bottom end of the inside of the L-shaped plate 9, and the top of the thrust spring 11 fits with the bottom of the sealing cover 6 to fix the collecting dish 7.

[0025] Reference Figure 3 As shown, in this embodiment: the inner wall of the air vent 5 is fixedly connected with a mounting bracket 14, and an exhaust fan 15 is installed on the top of the mounting bracket 14. The user operates the control cabinet 2 to turn on the heating device 4 to heat the internal temperature of the drying chamber 1, and turns on the switch of the exhaust fan 15 at the same time. The paper inside the drying chamber 1 is baked at high temperature, and the internal moisture evaporates into water vapor, which is sucked into the interior of the sealing cover 6 and discharged under the suction force of the exhaust fan 15, thereby preventing excessive water vapor in the drying chamber 1 from causing an increase in humidity and making it impossible to dry the paper.

[0026] Reference Figure 1 As shown, in this embodiment: a connecting pipe 16 is fixedly connected to the top of the sealing cover 6, and a condensing device 17 is installed on the top of the drying chamber 1. The user controls the heating device 4 through the control cabinet 2 to dry the moisture of the paper in the drying chamber 1. The moisture is evaporated into water vapor by heat, and the water vapor is sucked into the sealing cover 6 by the exhaust fan 15, and enters the interior of the connecting pipe 16 through the sealing cover 6. When passing through the condensing device 17, the water vapor is cooled and liquefied into water and is discharged through the connecting pipe 16, saving the cost of the pipeline required to discharge the water vapor to the outside.

[0027] Working principle of this utility model: The user controls the temperature of the heating device 4 through the control cabinet 2 to dry the paper entering the interior of the drying chamber 1. The water vapor generated during the drying of the paper enters the interior of the sealing cover 6 through the ventilation holes 5 and is discharged. During the process of discharging the water vapor, part of the water vapor liquefies inside the sealing cover 6 and drips downward. The collecting dish 7 below the sealing cover 6 collects the liquefied water droplets to prevent the water droplets from wetting the paper below again. By rotating the collecting dish 7, the limiting plate 10 is disengaged from the interior of the L-shaped plate 9, releasing the limitation on the collecting dish 7, facilitating the user to remove the collecting dish 7 to handle the water collected inside the collecting dish 7 and preventing the water inside the collecting dish 7 from overflowing. Place the collecting dish 7 below the sealing cover 6, align the limiting plate 10 on the collecting dish 7 with the notch of the collecting dish 7, rotate the collecting dish 7, and turn the limiting plate 10 into the interior of the L-shaped plate 9 to limit the collecting dish 7. At the same time, the thrust spring 11 at the bottom of the limiting plate 10 pushes the top plate 12 upward, increasing the friction between the top plate 12 and the bottom of the sealing cover 6, making the fixation of the collecting dish 7 more stable. Push the collecting dish 7 upward so that the limiting plate 10 moves upward, and the anti-slip pad 13 at the bottom of the limiting plate 10 separates from the bottom end inside the L-shaped plate 9. Rotate the collecting dish 7 to disengage the limiting plate 10 from the interior of the L-shaped plate 9, releasing the limitation on the collecting dish 7. After pouring out the water collected inside the collecting dish 7, align the limiting plate 10 with the notch of the L-shaped plate 9, push the collecting dish 7 upward to compress the thrust spring 11 so that the distance between the limiting plate 10 and the top plate 12 is less than the notch diameter of the L-shaped plate 9. Rotate the collecting dish 7, and after turning the limiting plate 10 into the interior of the L-shaped plate 9, release it. Under the thrust of the thrust spring 11, the bottom of the anti-slip pad 13 fits with the bottom end inside the L-shaped plate 9, and the top of the thrust spring 11 fits with the bottom of the sealing cover 6 to fix the collecting dish 7. By operating the control cabinet 2, turn on the heating device 4 to heat the temperature inside the drying chamber 1. At the same time, turn on the switch of the exhaust fan 15. The paper inside the drying chamber 1 is baked by high temperature, and the internal moisture evaporates into water vapor, which is inhaled into the interior of the sealing cover 6 under the suction of the exhaust fan 15 and discharged, preventing the humidity from increasing due to excessive water vapor in the drying chamber 1. Through the control cabinet 2, control the heating device 4 to dry the moisture of the paper inside the drying chamber 1. The moisture is evaporated into water vapor by heat, and the water vapor is inhaled into the sealing cover 6 by the exhaust fan 15, enters the interior of the connecting pipe 16 through the sealing cover 6, and when passing through the condensing device 17, the water vapor is cooled and liquefied into water and discharged or collected and utilized through the connecting pipe 16.
