When one group of filter plates 11 needs to be replaced, the card plate 95 is disengaged from the card slot 96 again, the handle 84 is reversed, and the linkage plate 81 is flipped in the opposite direction, thereby changing the flow direction of the condensed water. At this time, the card plate 95 enters the card slot 96 and limits the rotating rod 80. At this time, the filter plate 11 that needs to be replaced can be replaced. The personnel can replace the filter plate 11 by pulling it out through the through hole 13 and the connecting plate 12, so there is no need to stop the recovery and filtration, thereby improving work efficiency.

At this time, the handle 84 is rotated to rotate the rotating rod 80, so that the synchronous wheel 82 rotates through the synchronous belt 83 to make the two sets of synchronous wheels 82 and the rotating rod 80 rotate. At this time, the linkage plate 81 is turned over, and the pull plate 971 is released.
