Description

Technical Field

[0001] The present invention relates to the field of comprehensive utilization of solid waste, and in particular to a plastic bottle recycling and crushing system and a method for using the same. Background Art

[0002] With the development of industry, the use of plastic products has spread to all areas of industry, agriculture, and daily life. The amount of waste plastic generated daily around the world is incalculable, but the enormous pressure it places on the environment is obvious. To deal with this plastic waste, current methods generally include landfilling and incineration. However, since ordinary plastic waste takes a long time to degrade naturally, generally taking more than a hundred years to degrade, and the degradation process also produces a large amount of harmful substances such as methane, the landfill method has been criticized by many experts. Incineration also produces harmful gases, smoke, and other substances that directly affect the environment. Currently, portable beverages such as bottled mineral water are becoming increasingly popular due to their portability and cleanliness. This has led to the production of a large number of discarded plastic bottles. In order to recycle these discarded plastic bottles, they need to be crushed, cleaned, and separated from impurities.

[0003] Plastic bottles are relatively soft, so high-speed grinders are recommended for crushing. However, some water often remains in the bottles. This water can affect the high-speed grinding process, so it is important to remove any remaining water from the bottles before crushing.

[0004] Patent publication number CN108638380A discloses an intelligent plastic bottle dewatering and compression device. The device uses crushing blades on crushing rollers to rupture plastic bottles, allowing the liquid inside to flow into a water reservoir. The ruptured bottles are then compressed between compression rollers and subsequently sent to a recycling bin for storage. While this patent allows for the removal of liquid from plastic bottles, it does not guarantee that all liquid is expelled after the bottles are ruptured. Furthermore, the subsequent compression process compresses the bottles into irregular structures, which can easily trap liquid.

[0005] Therefore, a plastic bottle recycling and crushing system is needed, which can drain the water in the plastic bottles and crush the plastic bottles. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a plastic bottle recycling and crushing system and a method for using the same.

The width of the discharge pipe is smaller than the length of the plastic bottle, and a water outlet mesh is provided on the lower side of the discharge pipe. The outer axis of the cutting box is connected to a lever shaft, and a plurality of circumferentially evenly distributed levers are fixed to the lever shaft. The lever is located between the two driving turntables and the ends extend into the cutting box and the discharge pipe. The lever shaft drives the lever to move the plastic bottles in the lower end accommodating space into the discharge pipe. The cutting and water removal mechanism also includes a turntable motor that drives the turntable shaft and the lever shaft to rotate; the lower end of the discharge pipe is connected to a discharge hopper located above the inlet of the crushing mechanism.

[0008] The plastic bottles enter the cutting box from the primary hopper of the cutting and dewatering mechanism, and the rotation of the driving turntable causes the plastic bottles to fall into the accommodating space formed by the positioning groove and rotate with the driving turntable; the plastic bottles are cut by the cutting knife during the rotation, so that the middle position of the plastic bottle is partially cut, and the connecting plastic sheet is retained in the middle position; the cut plastic bottles rotate to the lower end of the cutting box, and the lever shaft drives the lever to move the plastic bottles in the accommodating space at the lower end into the discharge pipe. The width of the discharge pipe is smaller than the length of the plastic bottle, so that the plastic bottle is bent at the cutting position, and the water in the plastic bottle flows downward and flows out from the water outlet mesh on the lower side of the discharge pipe, thereby realizing the dewatering of the plastic bottle.

[0009] As an optimization, the discharge pipe is arc-shaped and adapted to the rotation trajectory of the lever. In this solution, the discharge pipe is arc-shaped and adapted to the rotation trajectory of the lever, so that when the lever rotates, the plastic bottle is moved from the inlet end of the discharge pipe to the outlet end.

[0010] As an optimization, the cutting and water removal mechanism further comprises a fixed water collecting plate, which is located below the discharge pipe. The water collecting plate in this solution collects and discharges the water discharged by the cutting and water removal mechanism.

[0011] As an optimization, the cutter is mounted on a cutter motor. The cutter in this solution is mounted on a cutter motor, thereby achieving rotary cutting.

[0012] As an optimization, the pulverizing mechanism includes a pulverizing box, a pulverizing shaft connected to the pulverizing box, and a pulverizing motor that drives the pulverizing shaft to rotate.

The pulverizing shaft is fixedly connected to a plurality of pulverizing blades, and the pulverizing box is fixedly connected to a plurality of fixed blades. The fixed blades and the pulverizing blades are staggered along the circumference of the pulverizing shaft. In this solution, the plastic bottles after dewatering fall from the discharge hopper into the secondary hopper of the pulverizing mechanism.

[0034] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0035] like Figures 1 to 10 As shown, a plastic bottle recycling and crushing system of the present invention includes a cutting and water removal mechanism and a crushing mechanism. The plastic bottles are firstly subjected to the cutting and water removal mechanism to remove water inside, and then are crushed by the crushing mechanism.

[0036] The cutting and water removal mechanism includes a cylindrical cutting box 1 and a turntable shaft connected to the cutting box 1 . The central axis of the cutting box 1 is horizontally arranged, and the turntable shaft is concentric with the cutting box 1 .

[0037] like Figure 3 As shown, two driving turntables 5 are fixedly connected to the turntable shaft. The two driving turntables 5 are circular discs and are arranged side by side. The upper end of the cutting box 1 is connected to a primary hopper 2. The width of the cutting box 1 is greater than the length of the plastic bottles 9. After the plastic bottles fall into the cutting box 1, the length direction of the plastic bottles is parallel to the axis of the cutting box 1. In this embodiment, the width of the lower end of the primary hopper 2 is slightly greater than the diameter of the plastic bottles, so that the plastic bottles are arranged side by side in sequence at the lower end of the primary hopper 2, so that they can enter the cutting box 1 in sequence.

[0038] Each plastic bottle recycling and crushing system of the present invention is suitable for plastic bottles of a single specification. In actual application, multiple plastic bottle recycling and crushing systems of different specifications can be used to adapt to plastic bottles of different specifications.

[0039] The outer ring of the driving turntable 5 is provided with a plurality of positioning grooves adapted to the diameter of the plastic bottles 9. The positioning grooves on the two driving turntables 5 are arranged in a one-to-one correspondence. The relative positioning grooves on the two driving turntables 5 and the cutting box 1 form a storage space for accommodating the plastic bottles 9, so that the plastic bottles 9 can be accommodated in the storage space and rotate along with the driving turntable 5.

[0040] The cutting and water removal mechanism further comprises a cutting knife 6 mounted outside the cutting box 1, and the cutting knife is mounted on a cutting knife motor 11. The cutting knife 6 is driven to rotate by the cutting knife motor 11 to cut the middle position of the plastic bottle.

[0041] The cutting knife is located at the position after the plastic bottle is rotated 90 degrees. The cutting knife extends into the cutting box 1 and partially overlaps with the accommodating space it passes through; the cutting knife 6 is located in the middle position of the two driving turntables 5 and is parallel to the driving turntable 5. The cutting knife partially cuts the plastic bottle in the accommodating space. The arc length of the cutting surface on the plastic bottle is approximately 0.5 to 0.9 times the circumference of the plastic bottle, so that more than half of the circumference of the plastic bottle is cut, which is convenient for bending the plastic bottle. The uncut position retains the connecting plastic sheet, and the plastic bottle can be moved and bent by toggling the connecting plastic sheet.

[0042] The lower end of the cutting box 1 is connected to a discharge pipe 3. The width of the discharge pipe 3 is smaller than the length of the plastic bottle 9. The connection between the discharge pipe 3 and the lower end of the cutting box 1 is smoothly transitioned. The plastic bottle 9 enters the discharge pipe 3 after the smooth transition, so that the plastic bottle is bent at the cutting position.

[0043] A lever shaft 7 is axially connected to the outside of the cutting box 1. Multiple levers 8 are fixedly attached to this shaft, evenly spaced around the circumference. These levers 8 are located between the two drive discs 5, with their ends extending into the cutting box 1 and the discharge pipe 3. Both the discharge pipe 3 and the cutting box 1 have slots for the levers 8 to pass through. The discharge pipe 3 is curved and conforms to the rotational trajectory of the levers 8. A water outlet mesh is provided on the underside of the discharge pipe 3, through which water from the plastic bottles flows out of the discharge pipe 3.

[0044] The cutting and water removal mechanism further comprises a fixed water collecting plate 10, which is located below the discharge pipe 3. The water collecting plate collects and discharges the water discharged by the cutting and water removal mechanism.

[0045] The lower end of the discharge pipe 3 is connected to a discharge hopper 4 located above the crushing mechanism inlet. The discharge hopper 4 is downwardly arranged, and the width of the discharge hopper 4 is greater than the length of the plastic bottles, thereby facilitating the plastic bottles to fall into the crushing mechanism.

[0046] The lever shaft 7 drives the lever 8 to move the plastic bottle 9 in the lower end receiving space into the discharge pipe 3.

[0047] The cutting and water removal mechanism also includes a turntable motor 12 for driving the turntable shaft and the lever shaft 7 to rotate; the turntable motor 12 drives the turntable shaft and the lever shaft 7 to rotate through a chain, and by adjusting the diameter of the sprocket, the lever 8 and the accommodating space are made to correspond one to one. Every time the turntable 5 rotates the spacing of one accommodating space, the lever 8 moves one workstation.

[0048] like Figures 4 to 10 As shown, the pulverizing mechanism includes a pulverizing box 16 , a pulverizing shaft 18 axially connected to the pulverizing box 16 , and a pulverizing motor 22 for driving the pulverizing shaft 18 to rotate. The pulverizing box 16 is fixed on the pulverizing frame 13 .

[0049] A secondary hopper 15 located below the discharge hopper 4 is provided at the upper end of the crushing box 16 , and the plastic bottles after dewatering enter the crushing box 16 through the secondary hopper 15 .

[0050] The lower end of the crushing box 16 is provided with a discharge port and a filter 17 is installed on the discharge port. The crushed finished product is filtered through the filter 17 and then discharged. The crushing mechanism also includes a finished product box 14 located below the discharge port for holding the crushed finished product.

[0051] A plurality of crushing blades 19 are fixedly connected to the crushing shaft 18. The crushing blades 19 are S-shaped blades and are arranged in a spiral along the circumferential direction. Gaps are left between adjacent crushing blades 19.

[0052] A plurality of fixed blades 20 are fixedly connected to the crushing box 16. The fixed blades 20 are located on one side of the crushing blade 19. Blade partitions 21 are fixed between adjacent fixed blades 20 to maintain a certain gap between adjacent fixed blades 20.

[0053] The fixed blades 20 and the crushing blades 19 are staggered along the circumference of the crushing shaft 18 so that the fixed blades 20 are inserted into the gaps between adjacent crushing blades 19 .

[0054] A method for using a plastic bottle recycling and crushing system comprises the following steps:

[0055] a. Plastic bottles 9 enter the cutting box 1 from the primary hopper 2 of the cutting and water removal mechanism. By driving the turntable 5 to rotate, the plastic bottles 9 fall into the accommodation space formed by the positioning groove and rotate along with the driving turntable 5;

[0056] b. Cut the plastic bottle 9 during the rotation process with a cutting knife, so that the middle position of the plastic bottle is partially cut, and the connecting plastic piece is retained in the middle position;

[0057] c. The cut plastic bottle 9 rotates to the lower end of the cutting box 1, and the lever shaft 7 drives the lever 8 to move the plastic bottle 9 in the lower end accommodation space into the discharge pipe 3. The width of the discharge pipe 3 is smaller than the length of the plastic bottle 9, so that the plastic bottle 9 is bent at the cutting position, and the water in the plastic bottle flows downward and out of the water outlet mesh on the lower side of the discharge pipe 3;

[0058] d. After the water is removed, the plastic bottles fall from the discharge hopper 4 to the secondary hopper 15 of the crushing mechanism. In the crushing box 16, the crushing blade 19 rotates, so that the plastic bottles are crushed by the staggered cutting of the crushing blade 19 and the fixed blade 20. The crushed finished product is filtered through the filter 17 and discharged.

[0059] Of course, the above description is not limited to the above examples. Technical features not described in the present invention can be achieved by or by adopting existing technologies, which will not be described here. The above embodiments and drawings are only used to illustrate the technical solutions of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention and should also fall within the scope of protection of the claims of the present invention.
