Besides adopting the structure, the transmission device can be driven in a straight line by using an air cylinder or an electric cylinder.
When the number of the turnover frames 3 is only two, the turnover driving mechanism does not need to be provided with a traction plate 8 any more, and as shown in fig. 12, the two turnover frames 3 can be pushed or pulled to rotate only through the boosting frame; when the number of the turnover frames 3 is three, only one traction plate 81 is required to be arranged on the turnover driving mechanism, and as shown in fig. 13, the three turnover frames 3 can be pushed or pulled to rotate through the boosting frame and the traction plate 81.

So designed, the silk screen is installed stably and is convenient to disassemble and assemble.
Preferably, the specification of the silk screen 1 is 100-200 meshes. Under the capillary action, water molecular groups in the air are easily stuck by the silk screen when passing through the meshes of the silk screen, so that the effect of collecting smaller water drops (water drops with the diameter of more than 0.3 mm) in the air is achieved, and the smaller water drops in the air are mostly intercepted. The higher the mesh number of the silk screen is, the better the effect of separating small water drops is, but the air pressure drop is large; otherwise, the pressure drop is small, and the effect of separating small water drops is slightly poor. In actual production, the customer can select proper silk screen specifications according to different needs.
The working principle of the lower water collector 18 will be specifically described below, taking the number of the turnover frames 3 as four as an example:
1) When the high-pressure fan is tested, the turbine speed reducer 12 is started to drive the transmission plate 13 to rotate to the position shown in fig. 9, so that the boosting frame pushes the turnover frames 31 and 32 to be parallel to the air inlet direction, and the rest turnover frames 32 and 34 are also rotated to be parallel to the air inlet direction under the linkage of the traction rod 8;
2) When the subsequent mass production is carried out, the turbine speed reducer 12 is started to drive the transmission plate 13 to rotate backwards to the position shown in fig. 7, under the pulling of the push plate 5, the two boosting rods 6 of the boosting frame are retracted, so that the turnover frames 31 and 32 are driven to rotate and the front parts of the turnover frames are intersected, the front surfaces of the silk screens 1 face the air inlet direction and the acute angle between the front surfaces and the air inlet direction is 45 degrees, the other turnover frames 33 and 34 are also rotated along with the front surfaces of all silk screens 1 under the linkage of the traction rods 8, and finally, the front surfaces of all silk screens 1 are spliced into an integral water collecting surface, so that small water drops in the air can be collected;
3) When the silk screen is required to be cleaned in the subsequent mass production period, the turbine speed reducer 12 is started to drive the transmission plate 13 to rotate forwards, and under the pushing of the push plate 5, the two boosting rods 6 of the boosting frame are opened, so that the turnover frames 31 and 32 are driven to rotate and intersect with each other, the reverse side of the silk screen 1 faces the air inlet direction and has an acute angle of 45 degrees with the air inlet direction, the rest turnover frames 33 and 34 also rotate along with the linkage of the traction rod 8, and finally, the reverse sides of all the silk screens 1 face forwards, so that the silk screen 1 can be backflushed and cleaned by using air, and the cleaning of the silk screen is ensured.

Comparing with a rotary dehumidifier; calculated according to the treated air quantity 20000m 3/h:
1) Adopts a rotating wheel dehumidifier: steam consumption is approximately 430kg, total power of the regenerative fan and the rotating wheel motor is approximately 8.0KW, operation cost in one day (according to 24 hours) is approximately (0.43×24×150 elements=1548 elements) + (8×24×0.5=96 elements) =1644 elements, and the operation cost in one year is approximately 32.88 ten thousand elements calculated according to 200 days.
2) The air dehumidifier adopting the invention comprises: the required refrigerating capacity is about 28000/kcal calculated according to the air inlet temperature of 20 ℃ and the cooling temperature of less than or equal to 15 ℃, the running cost is about 28000/860 multiplied by 24 multiplied by 0.5 yuan for one day (according to 24 hours) and is about 7.8 ten thousand yuan for one year according to 200 days.
In conclusion, the operation cost is reduced by about 32.88-7.8=25.08 ten thousand yuan in one year.
