This application discloses a washing and drying line for recycling PE agricultural film, relating to the technical field of plastic recycling. It includes a pretreatment module, a main treatment module, and a dewatering device. The dewatering device includes a body with a rotating drum and a rotating shaft rotatably mounted on it. The rotating shaft is coaxially arranged inside the drum and has spiral blades for propelling the material. A drive mechanism on the body drives the drum and shaft to rotate at different speeds. The body has an inlet communicating with a separation chamber and a solid outlet communicating with the separation chamber. A water guiding chamber is provided inside the drum, and several micropores communicating with the water guiding chamber are provided on the inner wall of the drum. A drain pipe communicating with the water guiding chamber is provided on the body. A pump unit is located on the side of the drain pipe away from the water guiding chamber, capable of inflating, deflating, and pumping water. This application has the effect of reducing the moisture content of the material.
