Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic drying, in particular to a recycled plastic drying device. Background Art
[0002] At present, the plastic processing industry generally uses underwater pelletizers to produce plastic pellets. The molten material at high temperature passes through the die hole under the action of the screw extrusion pressure. The extruded strip material is cut into pellets by the high-speed rotating cutter close to the die surface. The pelletizing cutter is in close contact with the die surface. After the pellets are cut off, they are thrown away from the cutter under the action of centrifugal force and transported to the cooling water. Then, they are transported to the dehydration dryer together with the cooling water for dehydration, so that the water and the pellets are separated.
[0003] However, in the process of dehydrating and drying the plastic particles, the existing plastic particle dryer directly discharges the water, and the dehydration effect of the dryer on the plastic particles is insufficient. After the plastic particles are dehydrated and dried, water stains still remain on the surface, which affects the storage of the plastic particles. Utility Model Content
