Abstract
The invention discloses a separation device of PET bottle flakes and labels that have high separation efficiency and can collect labels, comprising a separation box body. The separation box is internally provided with a separation channel which is a Z shape, the upper end of the separation channel is connected with an aspiration pipe that is provided with a pressure regulating valve, and the aspiration pipe is communicated with an air inlet of an exhaust fan, and the separation channel is also communicated with an outlet of a feeding hopper. The device used for separating bottle flakes and labels has the advantages of simple operation, high energy conservation efficiency and separation efficiency as high as 99 percent and continuous production; the device can realize dust cleaning effect while separating bottle flakes and labels, and the collected labels can also be used in otherwise.
Description
Technical field
The present invention relates to the separator that is used to separate PETG (being called for short PET) bottle fragment and label.
Background technology
In recent years, along with rising steadily of oil price, and the improving constantly of people's environmental protection consciousness, the recycling work of PET bottle also more and more comes into one's own.Because the PET bottle is inequality with the material that sticks on the label on the bottle---it is that material is made that label adopts polyvinyl chloride (being called for short PVC), polyethylene (being called for short PE), polypropylene (being called for short PP), paper usually; in removal process; in order to ensure the purity of salvage material, PET bottle fragment and label must be separated.Separation method commonly used at present is: different with the proportion of label according to the PET bottle fragment, send into the PET bottle fragment and the label that mix after the fragmentation in the water together, proportion swims in the water surface less than the label of water, proportion is greater than the bottle fragment of water submerged then, so just can realize the purpose that PET bottle fragment and label are separated.But the printing ink of some label is thicker, make label proportion greater than water, and the producer that has in recent years uses the PVC label in a large number in order to make the convenient and bright in color of label printing---PVC density just is difficult to even can not successfully they be separated with said method like this greater than water.Because a large amount of labels can't separate with PET bottle sheet, directly have influence on the quality of the PET bottle sheet of recovery, particularly PET is decomposed during afterwards hot-working of PVC, IV viscosity is reduced to the stage that can't use, and the product blackout that bottle sheet is made, therefore, can separation tags be to reclaim the key of PET bottle sheet.
Summary of the invention
Technical problem to be solved by this invention is: a kind of separative efficiency height will be provided, also can collect the PET bottle fragment of label and the separator of label.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the separator of PET bottle fragment and label, comprise: separate casing, in separating casing, be provided with " it " font split tunnel, the upper end of split tunnel is connected with aspiration channel, aspiration channel is provided with pressure regulation dish valve, and aspiration channel is connected with the air inlet of air exhauster; Split tunnel also is connected with the outlet of feed hopper.
On the air outlet of air exhauster, also be connected with the bag that gathers materials.
Above-mentioned " it " font split tunnel includes four bendings at least, and the outlet of feed hopper is connected first bending place.
Advantage of the present invention is: simple in structure, efficient height, separation rate up to 99%, and can produce continuously; Can also be used for others with the label that advances to collect.
Description of drawings
Fig. 1 is the structural representation of separator of the present invention;
Fig. 2 is the structural representation of the left apparent direction of Fig. 1;
Fig. 3 is the local structure for amplifying schematic diagram of " it " shown in Fig. 2 font split tunnel.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, the separator of described PET bottle fragment and label, comprise: be arranged on the separation casing 4 on the frame 5, in separating casing 4, be provided with " it " font split tunnel 6 with six bendings, the upper end of split tunnel 6 is connected with aspiration channel 12, aspiration channel 12 is provided with pressure regulation dish valve 2, and aspiration channel 12 is connected with the air inlet of air exhauster 1; Split tunnel 6 also is connected with the outlet of feed hopper 3, and the outlet of feed hopper 3 is connected first bending place of split tunnel 6.On the air outlet of air exhauster 1, also be connected with the bag 8 that gathers materials.In addition, when actual fabrication, also can on separation casing 4, a viewing window be set, can directly observe feed separation, monitor in real time.
The operation principle of the separator of said structure is: the mixture of PET bottle fragment after the fragmentation and label is added in the feed hopper 3, and they enter into split tunnel 6 under the effect of gravity, and in split tunnel 6, bottle sheet and label fall simultaneously; Meanwhile, start air exhauster 1, make and form negative pressure in the split tunnel 6; Because the size of broken back bottle sheet and label is more or less the same, but weight is really mutually far short of what is expected, the weight of bottle sheet is about about 4 times of label, and the buoyancy that negative pressure produces is identical, therefore, can utilize the negative pressure label that bulk density is lighter to extract out, heavier bottle sheet then continues to fall, and is finally discharged by the discharging opening 62 of split tunnel 6; Because split tunnel 6 is designs in a zigzag, like this, mixture is every through the bending place 61 shown in a Fig. 3, the bottle sheet will separate once with label, this machine is provided with three such bending corners altogether, can further improve separating effect, separation rate is up to 99%, and separated label is finally collected in the bag 8 that gathers materials.When separating different materials, can adjust the size of suction air volume by regulating pressure regulation dish valve 2, to adjust the size of negative pressure in the split tunnel 6, finally to guarantee the label come-up bottle sheet to fall be purpose, to realize separating smoothly of bottle sheet and label.
In sum, utilize this separation device to come separating bottle sheet and label, simple to operate, energy-saving efficiency is high, separation rate up to 99%, and can produce continuously; And in separating bottle sheet and label, also can reach the effect of dedusting; Can also be used for others with the label that advances to collect.
