Cleaning and rinsing, can be with the embodiment for removing the impurity in the plastic sheet：Recognize and select from plastic bottle
Go out PET bottle, carrying out break process to PET bottle obtains after plastic sheet, and plastic sheet enters the first friction cleaning machine
The first friction cleaning is carried out, the impurity in the plastic sheet is tentatively removed；Subsequently enter Hot-cleaning machine and carry out thermal cleaning, make bottle cap
Bubble through the water column and be separated, plastic sheet is then sunken to water, while melting the label binding agent in the plastic sheet, make residual label
Removing；Then the second friction that the plastic sheet that thermal cleaning is completed is delivered to rinse unit is cleaned by the first auger conveyor
Machine；Plastic bottle enters the friction cleaning of the second friction cleaning machine row second, removes the debris in the plastic sheet after being handled through thermal cleaning
With residual label；Enter back into potcher to be rinsed, debris, bottle cap and other impurities are further removed by density variation；
Eventually pass the second auger conveyor and clear water spray irrigation is carried out to plastic sheet again, deliver to drying device.Wherein, in some realities
Apply in example, the centrifugal dehydrator that the plastic bottle after the completion of washing enters drying device carries out preliminarily dried；Subsequently into duct type
Drier, plastic sheet enters from the charging aperture of duct type drier one end, and air blower is while from the blowing of electric heater direction, make wind quilt
Heating, heated wind blows plastic sheet, so that constantly reversion advances to the material receipts of discharging opening to plastic sheet inside pipeline
At storage, the moisture of plastic sheet is by hot blast drying in pipeline, and the aridity of discharging meets the requirement of deep processing；Last plastic sheet
Packing is collected at the baling press that the material collector with duct type drier connects, the process of whole removal of impurities cleaning is completed.
According to the above-mentioned technical solution, the beneficial effect of the embodiment of the present invention is：In the case of being different from prior art,
