Embodiment 1
[0084] Embodiment 1: To compare the parameters of this structure with the conventional exhaust mechanism, the set experimental conditions are as follows.
[0085] 1. Surface area of ventilation test tank: 1.5*0.8m
[0086] 2. Air cover 22 on both sides of the groove: traditional slit type air cover 22 and the exhaust mechanism of this structure
[0087] 3. Fan 6: exhaust air volume 2456m3 / h, wind pressure 1100Pa
[0088] 4. Chimney 7 outlet: the diameter is 315mm.
[0089] 5. Test bath: 75-85 degrees hot water
[0090] The table below is a comparison table of the suction parameters of the traditional slit-type wind cover 22 and the exhaust mechanism of the present structure.
[0091]
[0092]
[0093] As can be seen from the table above, the traditional air cover 22 and fan 6 are in the high-speed operation state of 50HZ for a long time, and there is still a lot of steam and exhaust gas overflowing from the liquid surface of the solution tank 1, resulting in a humid...
Embodiment 2
[0094] Embodiment 2: The driving assembly 21 can be a driving cylinder and a connecting rod structure. On the premise that the space permits, it can directly drive the flap 24 to move through the driving cylinder to realize the rotation of the flap 24, and then realize the opening and closing of the flap 24 Action, if the space is limited, the drive cylinder can realize the action of the turnover plate 24 through the connection structure.
Embodiment 3
[0095] Embodiment 3: The driving assembly 21 can be a rack and pinion structure, and a gear is arranged coaxially on the turning shaft of the turning plate 24, and a rack is arranged to mesh with the gear, and the rack moves up and down under the action of the cylinder or the motor screw to drive the gear Rotate, realized the rotation of turning plate 24.
