Abstract

The utility model discloses an environment-friendly plastic granulator. The environment-friendly plastic granulator comprises a crushing mechanism, a heating-melting mechanism and a grain-cutting cooling mechanism, wherein the heating-melting mechanism comprises a material barrel and a screw rod, wherein the material barrel is provided with an inner cavity; the screw rod is arranged in the inner cavity; the screw rod rotates in the material barrel by virtue of a power mechanism; a hopper and an extrusion mould head are arranged on the material barrel, wherein the hopper is used for feeding plastics to the material barrel; the extrusion mould head is used for extruding out the molten materials; a water outlet communicating the inner cavity of the material barrel with the outside is formed in the bottom of the material barrel; a gas outlet communicating the inner part of the material barrel with the outside is formed in the top of the material barrel; the gas outlet is connected with one end of a gas outlet tube; and the other end of the gas outlet tube is connected with a combustion furnace. According to the novel plastic granulator disclosed by the utility model, the gas is directly exhausted through the gas outlet during the processing process, and conveyed to the combustion furnace by the gas outlet tube, so that the gas is fed to the coke in the combustion furnace, and the combustible oil gas is sufficiently combusted, wherein the water vapor is immediately dried out and the harmful gas is decomposed under high temperature, therefore, no oil smoke is exhausted during the whole smelting-granulating process, the body health of workers is greatly ensured and the ambient environment is clean.

Description

The environmentally-friendly plastic comminutor

Technical field

The utility model relates to a kind of technics of reclaim of plastic waste processing equipment, and concrete is a kind of environmentally-friendly plastic comminutor.

Background technology

The recycling of waste or used plastics and resource development, it is the heightened awareness that comes from environment and resource, falling few waste or used plastics is a kind of life style to the pollution of environment and the minimizing wasting of resources, it is a major issue of benefiting the nation and the people, it is estimated that, often utilize one ton of waste or used plastics, but compare energy savings more than 85% with processing raw material, save processing charges 70-80%, be equivalent to save 20 tons, oil.

Waste plastic regeneration is processed; need first the waste or used plastics process to be cleaned; dry and then with screw extruder melting, the plasticizing of plastic regeneration pelletizer; be extruded into strip; pass through again cooling device cooling; adopt at last pelleter to be cut into particle, these particles advanced the technique deep processings such as blowing, injection moulding, calendering again and became various plastic products.

Traditional plastic granulator is adding man-hour; can produce a large amount of do not have burned dense oil smoke and other pernicious gases; will greatly not affect yield rate if do not discharge, if discharge can cause as inflating the pollution of environment, will bring huge pressure to environmental sanitation.

The utility model content

The purpose of this utility model is to provide a kind of simple in structure, easy to operate and health, the healthy environmentally-friendly plastic comminutor of assurance workman.

for solving the problems of the technologies described above, the utility model provides a kind of plastic granulator of environmental protection, comprise plastic crushing mechanism, heating and melting mechanism and pelletizing cooling body, described heating and melting mechanism comprises the barrel that is provided with inner chamber and is arranged on screw rod in inner chamber, described screw rod rotates in barrel by actuating unit, be provided with the extrusion die that plastics are sent into the hopper in barrel and the material of melting is extruded on described barrel, be provided with on described barrel and be communicated with inner with the extraneous exhaust outlet of barrel, be connected with an end of blast pipe on described exhaust outlet, the other end of blast pipe connects incinerator.

The utility model improves to be had, and is provided with expansion box between described blast pipe and incinerator, is provided with escape pipe on described expansion box, and described escape pipe connects incinerator.

The utility model improves to be had, and is provided with opening on described expansion box, is provided with the chamber door of the described opening of sealable sealing on described opening.

The utility model improves to be had, and is provided with sealing ring on described chamber door.

The beneficial effects of the utility model are: the plastic granulator of new structure; in process; gas is directly got rid of by steam vent, and passes through the incinerator that is delivered to of blast pipe, and incinerator heats barrel; gas is delivered to the coke in incinerator; flammable oil gas is fully burnt, and wherein steam is dryouied immediately, and pernicious gas also decomposes through high temperature; therefore whole melting granulating process does not have oil smoke to discharge, and has guaranteed greatly the health of employee's healthy and surrounding environment.
