Horizontal dehydrator

The invention belongs to the field of plastic material recovery and dehydration, and particularly relates to a horizontal dehydrator, accumulated water accumulated on the top wall of a mesh cylinder can be discharged into a water storage filler layer through a permeable filter plate for temporary absorption, and the accumulated water in the water storage filler layer is introduced to a water absorption part through a water guide rope; after the water absorption part absorbs water and expands, the two sides of the bottom of the water absorption part can extend towards the inclined plate side under the assistance of the water guide rope, and when wind force discharged into the corrugated telescopic pipe can enable the lifting plate to lift the outwards-turned top block through the lifting rod, discharged air is discharged into the movable groove through the air cavity and the air channel in sequence; the top arc plate moves down the pressing part and deforms under the action of wind resistance, then the pressin
