Problems solved by technology

[0005] In our country, since the recycling of PET bottles has just started, various technical research and equipment are relatively backward, and consumers do not know enough about the importance of recycling PET bottles, which leads to the inclusion of various wastes in the recycled PET bottles. The existing PET recycling The process has the following disadvantages: the cleaning effect is not good, the cleanliness of the plastic fragments obtained is not up to standard, and the cleaning cost is high

Embodiment 1

[0034] Such as figure 1 A kind of PET bottle flake reclaimed material production process shown, comprises the following steps:

[0035] Step 1, unpacking, unpacking the recovered whole bag of bottle bags through the unpacking machine, and place the unpacked plastic bottles at the station to be sorted. In practical applications, in order to improve the unpacking efficiency , the unpacking machine is set as a two-axis oil bottle unpacking machine, and the whole bag and the packaging bags filled with plastic bottles are quickly unpacked by the unpacking machine, and they are piled up and placed.

[0036] Step 2, material sorting, classify and screen the unpacked plastic bottles, separate and place plastic bottles of different materials by category, and place the sorted PET bottles at the station to be processed. Plastic bottles of different materials Bottles are automatically screened by screening machines and separated into categories.

[0037] Step 3, color separation and sor...

Abstract

The invention discloses a PET (Polyethylene Terephthalate) bottle flake reclaimed material production process which comprises the following steps: breaking by a bale breaker, classifying and screening broken plastic bottles, performing color separation and selection on the sorted PET plastic bottles through a color sorter, and separating the bottles according to colors; performing complete bottle prewashing, and sorting the sundries through a platform; crushing through a crusher, and feeding to a dehydrator for dehydrating; performing high-temperature thermal washing disinfection with alkali liquor, performing further high-speed friction and dehydration, and performing repeated cleaning and dehydrating; finally, feeding the PET bottle flakes subjected to repeated cleaning into a blowing machine for blowing, feeding the blown PET bottle flakes into a packaging machine for packaging, discharging out of the stock bin, and storing. According to the PET bottle flake reclaimed material production process disclosed by the invention, the PET bottle flake cleaning effect is excellent, the recovery production efficiency is high, the labor intensity is reduced, the cost is lowered, and the economic benefits are high.

Description

[0001] Technical field: [0002] The invention relates to the field of resource recovery, in particular to a process for recycling plastic bottles, in particular to a process for producing recycled PET bottle flakes. [0003] Background technique: [0004] Polyethylene terephthalate (PET) is produced by polycondensation of a diacid and a diol. In the past production practice, dimethyl terephthalate and ethylene glycol were used as monomers to produce polyethylene terephthalate through transesterification and polycondensation. However, polycondensation reaction between terephthalic acid and ethylene glycol is increasingly used in production practice to produce polyethylene terephthalate. Recycling polyethylene terephthalate is the most successful and popular example of polymer recycling. The recycling of polyester bottles in Europe has been growing steadily. In 2001, 344,000 tons of polyester bottles were collected, an increase of 20%, as of the end of 2006, the Recycling Asso...
