Description
Technical field
The present invention relates to green, Chemical Manufacture and plastic applications, and in particular to a kind of PET polyester recovery and processing system.
Background technology
Nineteen fifty-three, DuPont realize linear thermoplastic polymer PET first（Polyethylene terephthalate）Work
Industry metaplasia is produced.It is widely used as synthetic fibers, packing plastic bottle, engineering plastics and thin because it possesses outstanding physical and chemical performance
Product package bottle and its application field in the fields such as film, especially field of food are still constantly expanding.But due to PET
There is extremely strong chemical inertness under field conditions (factors), it is difficult to be biodegradable, substantial amounts of waste PET not only causes seriously to environment
Pollution, according to statistics, in PET productions with there are about 3-5% in process and will turn into waste material, and the PET products largely used are more
For one-time consumption product, so the yield of waste PET is huge, this physical resources to the mankind is a kind of huge waste.
The content of the invention
A kind of present invention seek to address that drawbacks described above, there is provided PET polyester recovery and processing system.
In order to overcome defect present in background technology, the technical solution adopted for the present invention to solve the technical problems is：
A kind of PET polyester recovery and processing system, including screening transmission belt, disintegrating machine, heated wash groove and centrifugal dehydrator, screening transmission
Band is connected with heated wash groove, and the outlet of heated wash groove is connected with centrifugal dehydrator, and centrifugal dehydrator is connected with disintegrating machine entrance,
Disintegrating machine export with high-pressure blast pipeline, high-pressure blast pipe outlet is connected with dissolving tank, dissolving tank and filter, filter and
Dryer is connected, and dryer is connected with recovery storage device.
In the preferred embodiment of the present invention, dissolving tank is built with dimethylbenzene.
In the preferred embodiment of the present invention, dimethylbenzene can be substituted by tetrahydrofuran.
In the preferred embodiment of the present invention, dryer temperature control is at 60-65 DEG C.
The beneficial effects of the invention are as follows：A kind of PET processing and recovery system, PET plastics, PET or contain PET
Other articles, be transported to heated wash groove by screening transmission belt, while rinsed by gravity, reject the thing of bottle cap etc
Product, centrifugal dehydrator is entered after rinsed, centrifugation goes to remove water the impurity such as dirt, then is just broken into the article necessarily greatly with disintegrating machine
Small fragment, high-pressure blast pipeline is delivered to, further remove the impurity such as dust, the dissolving tank containing dimethylbenzene is sent into after dedusting, is added
45 DEG C or so of heat, stir 1.5 hours, after dissolving PVC impurity, be sent into filter, filter out the PET fragments not being dissolved,
Into dryer, under conditions of being less than 65 DEG C higher than 60 DEG C, drying, storage device is recycled to after drying.Structure letter of the present invention
It is single, it can be applied in industrial production broad spectrum.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
As shown in figure 1, a kind of PET processing and recovery system, PET plastics, PET or other things containing PET
Product, heated wash groove is transported to by screening transmission belt, while is rinsed by gravity, reject the article of bottle cap etc, it is rinsed
Entering centrifugal dehydrator afterwards, centrifugation is gone to remove water the impurity such as dirt, then the article is just broken into a certain size fragment with disintegrating machine,
High-pressure blast pipeline is delivered to, further removes the impurity such as dust, the dissolving tank containing dimethylbenzene is sent into after dedusting, heats 45 DEG C of left sides
The right side, stir 1.5 hours, after dissolving PVC impurity, be sent into filter, the PET fragments not being dissolved filtered out, into drying
Machine, under conditions of being less than 65 DEG C higher than 60 DEG C, drying, storage device is recycled to after drying.Simple in construction, the Ke Yi of the present invention
Applied in industrial production broad spectrum.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
