Abstract
The waste plastic recovering method includes granulating waste plastic, mixing with polyethylene and making product of reused plastic. The present invention makes it possible to reduce pollution of waste plastic and save power.
Description
The present invention relates to a kind of recovery method of waste plastics.
The product of development in science and technology---plastics once brought people and greatly facilitated, and had solved the many problems in the clothing, food, lodging and transportion--basic necessities of life.But along with the increase day by day of plastics output, and waste plastics be difficult to the degraded, the polybag that waves has with the wind overworked treetop, the eaves in streets and lanes, is known as " white pollution ".Because can produce dioxin during the plastics burning, the method for burning can not work to plastic garbage.Therefore, need to adopt new technology to obtain the regeneration of waste plastics.
The sewage discharge problem is serious in traditional waste plastic regenerating process, and wastes energy, contaminated environment.
The purpose of this invention is to provide and a kind ofly do not waste energy, pollution-free and waste plastics recovery method that efficient is high.
For achieving the above object, the present invention takes following design: a kind of recovery method of waste plastics is characterized in that: the polybag of collecting is put into the cylinder that has many holes, add washing agent and clean; Polybag after washing is put into cutting machine, is cut into tiny plastic sheet, simultaneously water purification is drenched into, carry out secondary washing; Then by the conveyer belt drop that the has aperture branch that anhydrates, and enter in three grades of heating furnaces, controlling temperature respectively is 100,190,220 ℃; The water evaporates of frosting in the first order, plastics deliquescing in the second level, plastic molting in the third level.The hole that plastics after the fusing are opened from furnace outer wall is extruded, and is cooled in cold water, forms uniform plastic cord; In comminutor, plastic cord is divided into a section plastic pellet then, obtains the reworked material finished particle; Draining after twice washing reenters the drum wash waste plastics with the water that is mixed with washing agent, with the water reuse through precipitation with after handling; Regenerated plastics finished particle that obtains and polyethylene can produce plastic reclaimed product according to proportioning melting again in 7: 3.
Owing to adopt above method, the rinse stage that washs is combined with pulverizing,, subtly that the raw material rinsing is cleaner again when promptly having reduced pulverizing to the wearing and tearing of machine, kill two birds with one stone.In addition, traditional handicraft must have a dry run after the rinsing and between the melt pelletization, normally uses the mode that dries with the moisture removal in the raw material.Then save this operation among the present invention.Because fusion apparatus has adopted advanced technology, does not require very low moisture content, use raw material only need drain and both can.Reduced by an operation link, efficiency of equipment is improved greatly.
