Recycle production line and recycle technology of PET (Polyethylene Terephthalate) bottles

Abstract

The invention discloses a recycle production line and a recycle technology of PET (Polyethylene Terephthalate) bottles. The recycle production line comprises a first feeding device, a label removing device, a second feeding device, a manual sorting platform, a crusher, a first washing cage, a cleaning and separating device, a high-strength friction cleaning device, a hot-water cleaning device, a first dehydrator, a second washing cage, a second dehydrator, a rinsing device, a third dehydrator and a packer; the cleaning and separating device, the hot-water cleaning device and the rinsing device separately comprise a water tank, stirring cleaners and a mesh screen; each mesh screen tank is formed by sequentially connecting a plurality of arc-shaped mesh screen tank units with upward openings in series along the horizontal direction; a stirring cleaner is arranged above each arc-shaped mesh screen tank unit; each stirring cleaner comprises a rotary shaft and a stirring plate arranged on the rotary shaft; and the rotary shaft of each stirring cleaner is connected with a stirring cleaning driving mechanism. By adopting the production line, the cleaning of fragments is good in effect, high in speed and high in production efficiency.

Description

technical field [0001] The invention relates to a plastic recycling production line and technology, in particular to a PET bottle recycling production line and technology. Background technique [0002] Beverage bottles, oil bottles, etc. are usually made of PET, and a large number of PET bottles need to be recycled every day in daily life. The existing PET bottle recycling process mainly includes process steps such as feeding, screening, wet crushing, gravity rinsing, hot alkali cleaning, water rinsing, centrifugal dehydration, rinsing, centrifugal dehydration, packaging, etc. PET bottles are broken and cleaned to obtain clean PET Fragments, for example, the application publication number is CN104708730A "a recycling process for PET bottles" disclosed in the invention patent application. Among them, the "gravity rinsing" is to transport the crushed PET plastic fragments mixed with bottle caps into a cleaning bucket, and inject clean water into the cleaning bucket. The dens...

AI Technical Summary

Problems solved by technology

[0003] In the existing PET bottle recycling process, in the "gravity rinsing" or "rinsing" process, the materials to be treated are put into the cleaning bucket and rinsed by the flow of the cleaning medium. Because the impact of the cleaning medium on the fragments is small, the adhesion The separation effect of the impurities on the surface of the fragments and the bonded fragments is poor, and the impurities precipitated at the bottom of the cleaning bucket cannot be discharged in time, and the mixing of these impurities in the cleaning medium also affects the cleaning effect
