Multi-functional rubbing and separating device used for washing waste plastics

A multi-functional rubbing and separating device, comprising:

• a main body, a rotating axle and lapping blades;
• wherein a feeding port is disposed on one end of the main body and a discharge port is disposed on another end, the feeding port and the discharge port each located at an upper part of said main body;
• wherein the rotating axle and lapping blades are disposed inside said main body;
• the lapping blades are distributed on an outer cylindrical surface of the rotating axle;
• wherein a first inner space of the main body, close to the feeding port, forms a rubbing section, and a second inner space, close to the discharge port, forms a separating and dehydrating section;
• and
• wherein multiple through-holes are distributed on a sidewall of said main body at the separating and dehydrating section, and the sidewall of said main body at the rubbing section is a closed structure;
• wherein distribution density of said through-holes on the sidewall of said main body at the separating and dehydrating section gradually increases in a direction of materials transport;
• and wherein said lapping blades are spirally distributed and obliquely fixed on the outer cylindrical surface of said rotating axle.
