DETAILED DESCRIPTION

[0020] Depend on Figures 1 to 5 The utility model provides a rotary dehumidification, ventilation, filtering and regulating device for NMP solvent recovery, comprising a first ventilation mechanism 1 and a second ventilation mechanism 2, wherein the first ventilation mechanism 1 and the second ventilation mechanism 2 are respectively fixedly connected to the two ends inside the rotary mechanism 3 and extend to the outside of the rotary mechanism 3, and the first ventilation mechanism 1 and the second ventilation mechanism 2 are both composed of an air inlet hood 4, an adjustable air inlet assembly 5, a fan 6, an air inlet channel 7, a filter assembly 8 and a limiting column 9. The air inlet hood 4 is fixedly connected to the inside of the rotary mechanism 3 and extends to one end outside the rotary mechanism 3, the adjustable air inlet assembly 5 is connected to the middle position inside the air inlet hood 4, the fan 6 is fixedly connected to one end of the air inlet hood 4, the air inlet channel 7 is fixedly connected to the air outlet of the fan 6, the other end of the air inlet channel 7 is connected to the rotary wheel 10 inside the rotary mechanism 3, the filter assembly 8 is connected to one end of the air inlet hood 4 away from the fan 6, and the limiting column 9 is fixedly connected to the inside of the air inlet hood 4 and matches with the adjustable air inlet assembly 5;

[0021] Depend on Figures 2 to 5The adjustable air inlet assembly 5 is composed of a servo motor 11, a rotating shaft 12, a first ventilation mesh plate 13, a second ventilation mesh plate 14, an arc-shaped support plate 15, an arc-shaped closing plate 16 and an arc-shaped closing plate 2 17. The servo motor 11 is fixedly connected to the middle position of the bottom end of the air inlet cover 4, the rotating shaft 12 is fixedly connected to the output shaft of the servo motor 11, the first ventilation mesh plate 13 and the second ventilation mesh plate 14 are respectively fixedly connected to the two sides of the rotating shaft 12, the arc-shaped support plate 15 is fixedly connected to the first ventilation mesh plate 13 and the second ventilation mesh plate 14, the arc-shaped support plate 15 is provided with a first ventilation opening 18 and a second ventilation opening 19, the arc-shaped closing plate 16 is fixedly connected to the first ventilation mesh plate 13 and the second ventilation mesh plate 14, and the arc-shaped closing plate 16 is fixedly connected to the second ventilation mesh plate 17. The arc-shaped closing plate 16 and the arc-shaped closing plate 17 are respectively movably connected to the inside of the first vent 18 and the second vent 19 through the damping shaft 20. One side of the inside of the air inlet cover 4 is provided with a plurality of closing rollers 21 matching the arc-shaped closing plate 16 and the arc-shaped closing plate 17. The other side of the inside of the air inlet cover 4 is provided with a plurality of closing rollers 22 matching the arc-shaped closing plate 16 and the arc-shaped closing plate 17. The filter assembly 8 is composed of a support frame 23, a first filter plate 24 and a second filter plate 25. The support frame 23 is connected to one end of the inside of the air inlet cover 4. The first filter plate 24 and the second filter plate 25 are respectively plugged and connected to the two sides of the inside of the support frame 23.

[0022] When in use, the ventilation mechanism can select dual-channel air intake or single-channel air intake according to actual conditions. When dual-channel air intake is selected, the servo motor 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the first ventilation mesh plate 13 and the second ventilation mesh plate 14 to rotate, thereby driving the arc support plate 15 to rotate, so that the arc support plate 15 spans the entire air inlet cover 4 (such as Figure 2 As shown), at this time, the arc-shaped closing plate 16 and the arc-shaped closing plate 2 17 are not limited, so that the arc-shaped closing plate 16 and the arc-shaped closing plate 2 17 are opened through the action of the damping shaft 20, so that the first vent 18 and the second vent 19 are in a ventilation state. After the fan 6 is started, the external wind enters the interior of the air inlet hood 4 after being filtered by the filter assembly 8, and then passes through the first ventilation mesh plate 13 and the second ventilation mesh plate 14, and then passes through the first ventilation hole 18 and the second ventilation hole 19, so as to enter the interior of the runner 10. At this time, the first filter plate 24 and the second filter plate 25 perform filtering operations at the same time. When the first filter plate 24 and the second filter plate 25 need to be cleaned or replaced after being used for a period of time, the state of the adjustable air inlet assembly 5 is changed. If the second filter plate 25 needs to be cleaned or replaced, the servo motor 11 drives the first ventilation mesh plate 13, the second ventilation mesh plate 14 and the arc support plate 15 to move to one side of the interior of the air inlet hood 4 (as shown in FIG. Figure 3As shown), the arc-shaped closing plate 16 and the arc-shaped closing plate 2 17 are pressed together by closing the pressing roller 2 22, so that the arc-shaped closing plate 16 and the arc-shaped closing plate 2 17 close the first vent 18 and the second vent 19. At this time, only the first filter plate 24 is used to intake air, and the second filter plate 25 is in an inoperative state. The staff can clean or replace the second filter plate 25. If it is necessary to clean or replace the first filter plate 24, the servo motor 11 drives the first ventilation mesh plate 13, the second ventilation mesh plate 14 and the arc support plate 15 to move to the other side of the air inlet cover 4 (as shown in FIG. Figure 4 As shown), the arc-shaped closing plate 16 and the arc-shaped closing plate 2 17 are pressed together by closing the pressing roller 1 21, so that the arc-shaped closing plate 16 and the arc-shaped closing plate 2 17 close the first ventilation opening 18 and the second ventilation opening 19. At this time, only the second filter plate 25 performs filtering work, and the first filter plate 24 is in an inoperative state. The staff can clean or replace the first filter plate 24. Therefore, the entire operation process can be achieved without stopping the machine, which effectively improves convenience.

[0023] During operation, dual-channel ventilation can be achieved by setting a first ventilation mechanism and a second ventilation mechanism consisting of an air inlet hood, an adjustable air inlet assembly, a fan, an air inlet channel, a filter assembly and a limit column. Therefore, when the filter assembly is blocked, the filter plate can be cleaned or replaced by changing the air inlet duct, thereby improving the convenience of use. By setting a closing roller one and a closing roller two, the opening and closing of the arc-shaped closing plate one and the arc-shaped closing plate two can be controlled, thereby controlling the opening and closing of the air duct. By setting a filter assembly consisting of a support frame, a first filter plate and a second filter plate, single-sided filtering can be achieved, thereby facilitating the replacement of the first filter plate and the second filter plate during operation.
