Two linkage tooth grooves for installing the main rotating belt are arranged in the middle of each driving wheel.
The two sides of each movable plate, which are contacted with the demister, are respectively provided with a foam-rubber cushion, and the shape of each movable plate is the same as that of a gap in the demister.
The number of the screws is the same as that of the driving wheels, the screws are gradually shortened from the middle position to the two sides, and the screws do not exceed the outer diameter of the demister at the position.
The number of teeth of the driving wheel is reduced from the driving wheel at the middle position to two sides in sequence, so that the rotating speed of screws at different positions is changed, and the moving plates at different positions can reach the outer side or the inner side of the demister at the same time.
Compared with the prior art, the invention has the following beneficial effects:
1. the sponge pads are arranged on the two sides of the moving plate, which are in contact with the demister, can wipe the surfaces of the demister at different height positions, has no dead angle, and can clean the surfaces of the demister thoroughly under the cooperation of the spraying device.
2. The plurality of the screws are adopted, the length of the screws gradually decreases towards two sides along with the middle part of the tower body, and the screws are matched with the driving wheel with the largest number of teeth in the middle and the gradually decreasing number of teeth towards two sides, so that the time for the moving plates at different positions to reach the inner wall of the tower body is the same, and the synchronization can be realized.
3. The inside of the guide pipe is in a sealing state, so that water sprayed from the spray pipe can be prevented from being sprayed onto the driving wheel and the driven wheel, the normal use of the device can be prevented from being influenced due to rust of the driving wheel and the driven wheel, and the service life of the device can be prolonged.
