Description

Technical Field

[0001] The invention relates to the technical field of solid material separation and recovery, and in particular to a paper-plastic-aluminum packaging material recovery device. Background Art

[0002] Paper-plastic-aluminum composite packaging is a common packaging material. Composed of polyethylene, paper, and aluminum foil, it is a high-tech food preservation method widely used in packaging for milk and soft drinks. With increasing environmental awareness and the scarcity of raw materials, the recycling of paper-plastic composite packaging has become increasingly necessary. Recycling paper-plastic composite packaging typically involves separating the paper base from the remaining aluminum foil and plastic. Currently, wet separation techniques are commonly used to separate aluminum-plastic composite packaging materials, where the aluminum-plastic composite packaging is immersed in a separator, which dissolves or swells the material to break the adhesion between the layers, thereby separating the aluminum and plastic.

[0003] In the prior art, when separating paper-plastic-aluminum composite packaging materials, the paper-plastic-aluminum composite packaging materials are generally first placed in a hydraulic pulper to separate the paper base from the aluminum-plastic material, and then chemical reagents are used to dissolve the aluminum foil or plastic to achieve separation. However, paper-plastic-aluminum is mostly used for milk or beverage packaging, and there is usually residual liquid in milk or beverage cartons. If the residual liquid is not removed in advance, the recycling quality of the paper-plastic-aluminum material will be greatly reduced.

[0019] 3. The present invention breaks up the packaging material by arranging a paper base separation component and a discharge port blocking component. The paper base of the packaging material that has been soaked in water for a long time is separated from the aluminum and plastic. The paper base separation shaft and the spiral separation blade rotate at high speed to make the pulp float on the upper layer of the water. The pulp then enters the discharge barrel from the discharge port to separate the pulp from the aluminum and plastic, thereby facilitating the classification and recycling of paper, plastic and aluminum packaging materials.

After no residual liquid flows out of the packaging material, the extrusion component 9 is separated from the packaging material by adjusting the driving component 8; then, the baffle plate adjustment component 10 is adjusted to make the four baffle plates 7 slide outward in the chute 50, and the four baffle plates 7 are separated, and the four baffle plates 7 are also separated from the top of the waste liquid barrel 5. The packaging material slides from the pressing plate 6 to the lower part of the recycling barrel 1, and a sufficient amount of water is injected into the recycling barrel 1 through the water injection pipe 14; then the paper base separation component 11 is opened to separate the paper and aluminum plastic in the packaging material, and then the discharge port blocking component 13 is adjusted, and the paper pulp floating on the upper layer enters the discharge barrel 3 from the discharge port 12, and then is discharged from the bottom of the discharge barrel 3 and further processed for recycling; the aluminum plastic at the bottom of the recycling barrel 1 is directly discharged, and then dissolved by chemical reagents to further separate the aluminum foil from the plastic.

[0037] As attached Figure 7 As shown, the top of the waste liquid barrel 5 is set to be open; four fixing plates 15 are installed at equal intervals on the bottom of the outer wall of the waste liquid barrel 5; each of the fixing plates 15 is fixedly connected to the support plate 4 by a screw 16.

[0038] As attached Figure 3 , Attachment Figure 7As shown, the pressing plate 6 is configured to be truncated cone-shaped; a support rod 17 is fixedly mounted at the inner center of the waste liquid barrel 5 , and the pressing plate 6 is fixedly mounted on the upper end of the support rod 17 ; a plurality of arc-shaped leakage holes 18 are provided on the pressing plate 6 .

[0039] As attached Figure 1 , Attachment Figure 3 , Attachment Figure 9 As shown, the driving assembly includes a driving motor 19 fixedly installed at the top center of the recycling barrel 1; a driving screw 20 is installed at the output end of the driving motor 19; and an extrusion assembly 9 is threadedly installed on the driving screw 20.

The driving motor 19 is turned on (the driving motor 19 is connected to the power supply and the controller), and the driving motor 19 drives the driving screw 20 to rotate, and further drives the truncated cone-shaped extrusion block 21 and the pushing plate 25 to move downward synchronously. The pushing plate 25 first contacts the packaging material on the pressing plate 6. As the driving screw 20 continues to rotate, the truncated cone-shaped extrusion block 21 continues to move downward, thereby further driving the extrusion needle 22 to pass through the through hole 27 and then downward to pierce the packaging material on the pressing plate 6, thereby The residual liquid in the packaging material flows into the waste liquid barrel 5 from the arc-shaped leakage hole 18; when there is no residual liquid flowing out of the packaging material, the drive motor 19 is rotated in the opposite direction, further driving the drive screw 20 to rotate in the opposite direction, thereby further driving the truncated cone-shaped extrusion block 21 to move upward. Since an extrusion spring 26 is installed between the connecting ring 24 and the inner top wall of the annular cavity 23, the push plate 25 will move upward only after the truncated cone-shaped extrusion block 21 moves upward for a distance.
