Embodiment Construction

[0009] Now with reference to the accompanying drawings, the smog elimination process of the present invention is further described in detail: when the old plastic raw materials are smelted and granulated, the old plastic raw materials that enter from the feed port of the recycled plastic granulator are driven by the granulator screw. Entering the cylindrical shell, the front section of the shell is heated with coke, called the high temperature section, so that the raw material entering the inside becomes a slurry in a molten state. Then the slurry is continuously driven by the rotating screw, and then enters the heat preservation section, and finally extruded from one end into a soft noodle shape, and then cooled and pelletized to complete the granulation process. Due to the oil and water in the old plastic raw materials are vaporized in the high temperature section at the same time, producing gas with a certain pressure, which must be removed before entering the heat preservat...

Abstract

The present invention relates to extrusion type plastic pelletizer, and especially smoke-less regenerated plastic pelletizer without exhausted smoke and harmful gas during smelting and pelletizing. The present invention features that one smoke eliminating unit is connected to the exhaust port of an available pelletizer to collect exhausted inflammable gas, water vapor and other harmful gas, which are re-flowed to high temperature heating area for being burnt out. The pelletizer without exhausted smoke and harmful gas is favorable to the health of the operator and preventing secondary environmental pollution.

Description

technical field [0001] The invention relates to a plastic granulation machine, in particular to a smokeless regenerated plastic granulator which emits no smoke when smelting old plastics for regeneration and granulation. Background technique [0002] Someone abroad once said that "the invention of plastic bags is the worst invention of human beings". He refers to the large amount of domestic waste generated after the non-degradable plastic bags, films and other plastic products are discarded, which seriously pollute the living environment of human beings. Especially in my country, due to the large population, there are tens of billions of various plastic bags discarded every day, which brings huge pressure to environmental sanitation. Of course, it also provides a rich source of raw materials for people who rely on picking up trash for a living and the old plastic recycling industry. However, these raw materials are seriously oily. Although they have been sorted and cleaned...
