Environment-friendly granulator for recycling waste plastics

Abstract

The invention provides an environment-friendly granulator for recycling waste plastics, belongs to the technical field of granulators, and aims to solve the problem that when the granulator downwards extrudes molten plastics, the extruded molten plastics have relatively high viscosity and easily adhere to the inner wall of a discharging receiving hopper. The environment-friendly granulator for recycling the waste plastics comprises a barrel body, wherein a rotary driving mechanism is arranged at the upper end in the barrel body, and a screen is mounted at the lower end in the barrel body; and a crushing hopper is arranged on the right side of the top end surface of the barrel body, and a cooling mechanism is arranged on the lower portion of the left side of the barrel body. Through the arrangement of the cooling mechanism, an air blowing motor is started, a double-end rotating shaft of the air blowing motor drives air blowing fan blades and a second worm to rotate correspondingly, external air is blown into an air blowing cover through the rotating air blowing fan blades, then air is evenly blown away to the granular molten plastics in the cut-off and falling process through air blowing holes in the air blowing cover, so that the granular molten plastics are rapidly cooled, and the granular molten plastics are not prone to adhering to the inner wall of the discharging receiving hopper.

Description

technical field [0001] The invention belongs to the technical field of granulators, and more specifically relates to an environment-friendly granulator for recycling waste plastics. Background technique [0002] Plastic recycling refers to the use of certain recycling processes to recycle and reuse waste plastics to achieve the purpose of turning waste into treasure. At present, my country's waste plastics are mainly plastic films, plastic yarns and woven products, foam plastics, plastic packaging boxes and containers, daily-use plastic products, plastic bags and agricultural mulch films. [0003] For example, application number: CN201710680500.8 The present invention relates to the technical field of plastic recycling and granulation, in particular to a waste plastic recycling and granulation machine, comprising: a feeding hopper and a melting chamber below the feeding hopper; the melting chamber includes a cylindrical shell Body and a stirring device arranged inside the c...

Problems solved by technology

[0004] Based on the retrieval of the above-mentioned patents, it is found that when processing waste plastics, a granulator is usually used. When the above-mentioned granulator is used, although the L-shaped blades on the rotating shaft can avoid the accumulation of raw materials, causing the agitation to be stuck or the distribution of raw materials However, the above-mentioned granulator still has the following deficiencies in the actual use process, such as: due to the lack of effective crushing structure in the above-mentioned granulator, when the waste plastic with a large volume enters the barrel directly through the feed hopper When it is inside, because the waste plastic with larger volume needs longer melting time than the waste plastic with small volume, the melting efficiency of the granulator is reduced, and the above-mentioned granulator is feeding the molten plastic to When extruding downward, due to the high viscosity of the extruded molten plastic, once it adheres to the inner wall of the discharge hopper, it is difficult to clean up, which reduces the practicability of the pelletizer.
