Abstract

The invention discloses a multi-stage cooling device suitable for antioxidant environment-friendly plastic particle extrusion. The multi-stage cooling device comprises a first cooling box and a second cooling box. A feeding opening is formed in the upper portion of the first cooling box, and a spraying assembly is installed on one side of the upper portion in the first cooling box. Plastic particles are subjected to water cooling through the water spraying assembly, water drops on the plastic particles are vibrated to fall to the bottom of the first cooling box through a vibration assembly, so that the cooling and drying effects are achieved, cold air is blown out through a cooling assembly to cool the plastic particles for the second time, and then the plastic particles enter the second cooling box along a baffle, slide to a discharge port along a first inclined plate, a second inclined plate and a third inclined plate, and are cooled and dried for the third time through fans at the bottom and on the two sides during the period, so that the quality of the plastic particles is improved; and water in the first cooling box is cooled through a refrigeration assembly, so that the cooling efficiency is better.

Description

technical field [0001] The invention relates to a multi-stage cooling device, in particular to a multi-stage cooling device suitable for extrusion of anti-oxidation and environment-friendly plastic pellets. Background technique [0002] In plastic extrusion molding equipment, the plastic extruder is usually called the main engine, and the subsequent equipment plastic extrusion molding machine is called the auxiliary machine. Plastic extruder derives twin-screw, multiscrew, even does not have different types of machines such as screw rod by original single screw rod through 100 years of development. [0003] In the prior art, most cooling methods for anti-oxidation and environmentally friendly plastic pellets directly use water for cooling, but the temperature of the cooling water will increase after use, so that the cooling effect will gradually decrease, thereby affecting the quality of plastic pellets. Contents of the invention [0004] The technical problem to be solve...
