Waste plastic cyclic cleaning equipment and waste plastic cleaning recycling production line

The invention discloses waste plastic cyclic cleaning equipment and a waste plastic cleaning recycling production line adopting the waste plastic cyclic cleaning equipment. A homogenizing feeding spiral, a sand washing channel for receiving materials from the homogenizing feeding spiral and a sand water cyclic utilization device used for receiving sand water media from the sand washing channel areincluded. The sand washing channel comprises a plurality of cleaning pipes which are sequentially in communication. Stirring conveying rods are arranged in the multiple cleaning pipes. For every twoadjacent cleaning pipes, the cleaning pipe located at the front position can stir the materials through the corresponding stirring conveying rod and conveys the materials to the cleaning pipe locatedat the rear position. The sand water cyclic utilization device is used for conducting purifying treatment on the received sand water media, and treated sand materials and water are conveyed to the homogenizing feeding spiral an
