Efficient environment-friendly plastic granulation device

Abstract

The invention relates to the field of plastic processing, in particular to an efficient environment-friendly plastic granulation device. The plastic granulation device comprises a feeding extrusion device, a hot cutting device, a cold cutting device and a cooling discharging device. According to the high-efficiency environment-friendly plastic granulation device, accumulated plastic particles after granulation are not easy to stick together, and the produced plastic particles can be screened and classified to ensure the effect of uniformity of the plastic particles; the cut plastic particles are air-dried by means of wind transportation to ensure that the plastic particles are mutually separated directly and cannot stick together; dual processes of cold cutting and hot cutting are integrated, switching or simultaneous production can be performed according to demands, waste gas is washed by three layers of spray pipes, an adsorption layer can adsorb toxic and harmful gases in the gas, the gas is effectively purified, and pollution is reduced. A waste liquid tank can collect waste liquid generated in the washing process, so that secondary pollution is prevented, and the environment is further protected.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to an efficient and environment-friendly plastic granulation equipment. Background technique [0002] The working principle of plastic granulation is: the plastic is plasticized and melted by the screw extruder, extruded into strips or strips through the die hole, cut into granules by the granulation equipment, and then subjected to secondary cooling to obtain Plastic granules of desired particle size. Extrusion forms can be divided into hot cut and cold cut. The so-called eager cutting refers to the method of pelletizing the material in a molten or semi-molten state after being extruded from the die hole of the machine head; while cold cutting refers to the method of pulling the material into strips after being extruded from the die hole of the machine head, and then enters the The method of pelletizing after cooling in a water tank. [0003] At present, the plastic granulation...

AI Technical Summary

Problems solved by technology

[0003] At present, the plastic granulation process cannot control the cooling effect, which affects the quality of the granulation. At the same time, it is impossible to switch between hot cutting and cold cutting on one piece of equipment as needed, which makes the equipment use range relatively single and the efficiency is not high. On the other hand, The waste gas produced by the granulator in the production process is not treated, which will seriously pollute the environment; the above shortcomings are not conducive to the promotion of plastic granulators
