Description

Technical Field

[0001] The invention relates to the technical field of plastic waste recycling, and in particular to a plastic crushing and cleaning integrated device. Background Art

[0002] In the recycling operation of waste plastic products, in order to reduce the difficulty of subsequent processing and reduce the quality risk of subsequent products, it is necessary to crush and clean the plastic products. In the related technology, when crushing and cleaning the plastic products, the waste plastic products are first put into the crusher, cut into small pieces or fragments by a knife, and then the fragments of the plastic products are cleaned through a cleaning tank. A stirring mechanism or a stirring mechanism is generally provided in the cleaning tank to continuously stir the cleaning liquid to clean the plastic fragments. When using the cleaning tank to clean the plastic fragments, there are problems of unsatisfactory cleaning effect and low cleaning efficiency.

[0003] The patent document with the authorization announcement number CN116985302B discloses a plastic bottle crushing and cleaning line, including a label stripper, a conveyor belt is arranged at the discharge position of the label stripper, the other end of the conveyor belt is arranged at the upper part of the crusher feed position, and a cleaning machine is arranged on the other side of the crusher. The label stripper is used to remove labels from plastic bottles, the conveyor belt is used to transport the plastic bottles after label stripping, the crusher is used to crush the plastic bottles after label stripping, and the cleaning machine is used to clean the crushed fragments. The cleaning machine includes a body, and a transmission bin is fixedly connected to the upper part of one side of the body. When the cleaning machine cleans the plastic fragments, the servo motor and the rotating shaft drive the angle frame to rotate, and the cleaning liquid and the plastic fragments are stirred by the angle frame. The grid plate on the angle frame can rotate synchronously when the angle frame rotates, so that the grid plate can roll down the plastic fragments floating on the cleaning liquid during rotation, so that the plastic fragments can be fully contacted with the cleaning liquid.

[0004] Some of the recycled plastic products will have some dirt attached to them. After the plastic products are crushed, the plastic fragments with dirt attached to them are heavier and will sink to the bottom of the cleaning liquid. The dirt has a stronger adhesion to the plastic fragments, so it is difficult to clean such plastic fragments. However, it is relatively easy to clean the plastic fragments floating on the surface of the cleaning liquid. When the cleaning machine in the above patent document is working, it stirs the cleaning liquid by rotating the angle frame and rolls down the plastic fragments floating on the cleaning liquid through the grid plate. However, the cleaning effect on the plastic fragments deposited at the bottom of the cleaning liquid is poor. In addition, the cleaning machine in the patent document operates intermittently, and all the plastic fragments in the cleaning machine need to be cleaned each time. Due to the different cleaning difficulties of floating plastic fragments and heavy plastic fragments, the overall cleaning time of the plastic fragments is longer. After the cleaning machine completes the cleaning operation, it is affected by the angle frame, grid plate and other structural parts used to stir the cleaning liquid set inside it, and there is still a problem that the cleaned plastic fragments are inconvenient to collect, which further affects the processing efficiency of the plastic fragments during the recycling process.

[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figure 1 and Figure 2 As shown, the integrated plastic crushing and cleaning device of the present invention comprises a body 1, on which a crushing mechanism 11, a conveying mechanism and a cleaning mechanism are provided. The crushing mechanism 11 is used for cutting and crushing plastic products. At least two crushing rollers and a plurality of crushing blades are provided inside the crushing mechanism 11, and each crushing blade is provided on the peripheral side of the crushing roller. When the crushing roller rotates, the added plastic products are cut and crushed. The conveying mechanism conveys the crushed plastic fragments to the cleaning mechanism for cleaning. The feeding end of the conveying mechanism is opposite to the discharging end of the crushing mechanism 11, and the discharging end of the crushing mechanism 11 is located on the upper side of the feeding end of the conveying mechanism. The crushed plastic fragments fall into the feeding end of the conveying mechanism. The conveying mechanism comprises a conveying channel 12 and an auger 13. The height of the conveying channel 12 decreases along its conveying direction, that is, the conveying channel 12 is inclined downward along the conveying direction of the material. The auger 13 is arranged in the conveying channel 12 and is coaxially arranged with the conveying channel 12. The auger 13 is connected to a motor, and the motor drives the auger 13 to rotate.

[0034] The cleaning mechanism includes a cleaning tank 14, a collecting tank 15, a cleaning piece 2 and a driving assembly. Cleaning liquid is injected into the cleaning tank 14, and clean water or cleaning liquid can be injected into the collecting tank 15. The collecting tank 15 is used to temporarily store the cleaned fragments. A feed port 141 and a discharge port 142 are provided on the cleaning tank 14. The discharge end of the conveying mechanism is connected to the feed port 141. The collecting tank 15 and the cleaning tank 14 are connected through the discharge port 142. The cleaning piece 2 is cylindrical, and a plurality of through holes are evenly provided on the surface of the cleaning piece 2 so that the cleaning liquid can fully contact with the fragments in the cleaning piece 2 through the through holes, and the impurities cleaned can also be discharged from the cleaning piece 2 through the through holes. The fragments enter the cleaning piece 2, and the driving assembly drives the cleaning piece 2 to rotate, so that the cleaning piece 2 is fully in contact with the cleaning liquid and the fragments are fully cleaned.

[0035] like Figures 2 to 6 As shown, the rotating axis of the driving component is horizontally arranged, and the axial direction of the cleaning member 2 is inclined. The driving component drives the cleaning member 2 to rotate around the rotating axis of the driving component. When the cleaning member 2 rotates, its two ends are in contact with the two opposite inner walls of the cleaning tank 14 and slide along a circular trajectory. One end of the cleaning member 2 is the feeding end, and the other end is the discharging end. During the rotation of the cleaning member 2, the feeding end of the cleaning member 2 and the feeding port 141 move relative to each other, and the discharging end of the cleaning member 2 and the discharging port 142 move relative to each other. When the feeding end of the cleaning member 2 and the feeding port 141 are relative to each other, the fragments enter the cleaning member 2 from the discharging end of the conveying mechanism, and when the discharging end of the cleaning member 2 and the discharging port 142 are relative to each other, the fragments enter the collecting tank 15 from the discharging end.

[0036] In order to prevent debris from entering the cleaning tank 14 through the feed port 141 when the feed end of the cleaning piece 2 is misaligned with the feed port 141, and also to prevent material discharged from the discharge port 142 of the cleaning piece 2 from entering the cleaning tank 14 when the discharge end of the cleaning piece 2 partially overlaps with the discharge port 142, a sealing plate 24 is respectively provided at the feed end and the discharge end of the cleaning piece 2, wherein the sealing plate 24 can be a circular plate, and the center of the sealing plate 24 is located on the rotating shaft of the driving component, so that when the driving component drives the cleaning piece 2 to rotate, the feed port 141 and the discharge port 142 are not connected to the inside of the cleaning tank 14, effectively ensuring that the discharge port 142 and the feed port 141 are only connected to the cleaning piece 2.

[0037] The driving assembly includes a driving source, a worm wheel 22, a worm 23, a guide member 21 and a connecting member 211. The connecting member 211 is fixed relative to the inside of the cleaning tank 14. A circular hole is provided on the connecting member 211 for installing the guide member 21. The guide member 21 is rotatably installed at the circular hole. The guide member 21 is fixedly sleeved on the outside of the cleaning member 2. The worm wheel 22 is fixed to the guide member 21. The driving end of the driving source is connected to the worm 23. The worm 23 is meshed with the worm wheel 22. The driving source can be a motor. When the driving source drives the worm 23 to rotate, the worm 23 drives the worm wheel 22 to rotate. The worm wheel 22 further drives the guide member 21 to rotate, and the cleaning member 2 rotates with the guide member 21.

[0038] The process of the cleaning member 2 rotating from its feed end relative to the feed port 141 to its discharge end relative to the discharge port 142 is a cleaning cycle of the cleaning member 2. In a cleaning cycle, the feed end of the cleaning member 2 is first relative to the feed port 141, and the debris is pushed into the cleaning member 2 by the auger 13. The light debris is located on the upper side of the cleaning member 2 and contacts the upper side of the inner wall of the cleaning member 2. The heavy debris sinks in the cleaning member 2 and moves to the bottom of the cleaning member 2 due to the attachment of mud or other impurities. The driving component drives the cleaning member 2 to rotate. When the cleaning piece 2 is moved, the feed end of the cleaning piece 2 gradually staggers with the feed port 141, and the feed end of the cleaning piece 2 rotates from top to bottom along a circular path. The center of the circular path coincides with the center of the sealing plate 24. Light debris always tends to float upward, while heavy debris tends to slide to the bottom. The cleaning piece 2 will drive the debris inside it to move within the cleaning piece 2 during a cleaning cycle. In addition, because the cleaning piece 2 is completely immersed in the cleaning liquid, it can ensure that the debris is fully in contact with the cleaning liquid, so as to improve the cleaning effect and cleaning efficiency of the debris.

[0039] Since the adhesion between the impurities on the light debris and the debris is weak, it is easier to clean. After a cleaning cycle is completed, the discharge end of the cleaning member 2 is opposite to the discharge port 142, and the discharge end of the cleaning member 2 is located at a high place. The cleaned debris will float to the discharge end of the cleaning member 2 and enter the collecting tank 15 from the discharge port 142, floating on the surface of the collecting tank 15. If the mud or other heavy impurities on the debris are not thoroughly cleaned, the debris will not float up, but will still remain in the cleaning member 2, and move in the cleaning member 2 with the rotation of the cleaning member 2, and will not affect the feeding operation of the cleaning member 2 in the next cleaning cycle, until the mud or impurities on the heavy debris are thoroughly cleaned, and enter the discharge port 142 from the discharge end of the cleaning member 2 with the clean debris, and finally enter the collecting tank 15. The clean debris floating on the surface of the collecting tank 15 is also greatly facilitated because there is no interference from other structural parts, which greatly facilitates the collection of clean debris. The debris can be manually picked up using a mesh device, or it can be collected by other automatic collection equipment. After the debris is collected, it enters the subsequent processing steps.

[0040] In order to further make the fragments fully contact with the cleaning liquid inside the cleaning part 2, a plurality of protrusions are provided on the inner wall of the cleaning part 2. When the cleaning part 2 is connected with the feed port 141 and the discharge port 142, each protrusion is located on the side of the cleaning part 2. When the cleaning part 2 rotates, the contact between the fragments and the protrusions will promote the flipping of the fragments, thereby improving the cleaning effect of the fragments.

[0041] After the impurities are discharged from the cleaning member 2, due to the different densities of different impurities, some light impurities float on the surface of the cleaning liquid, and some impurities with higher density are deposited at the lower end of the cleaning tank 14. When the cleaning member 2 rotates in the cleaning tank 14, it will disturb the cleaning liquid. As the impurities accumulate at the bottom of the cleaning tank 14, when the cleaning member 2 rotates to approach the bottom of the cleaning tank 14, it will cause disturbance of the cleaning liquid at the bottom of the cleaning tank 14 and stir the impurities deposited at the bottom of the cleaning tank 14. The stirred impurities may re-enter the cleaning member 2 and interfere with the cleaning operation of the debris.

[0042] In order to reduce the interference of deposited impurities on debris cleaning, two receiving grooves 16 for accommodating impurities are further provided inside the cleaning tank 14. The two receiving grooves 16 are respectively longitudinally opposite to the two ends of the cleaning member 2. A cleaning assembly is also provided inside the cleaning tank 14. The cleaning assembly includes a driving member 3, a reciprocating screw rod 31 and a push plate 32. The reciprocating screw rod 31 is arranged inside the cleaning tank 14. The driving end of the driving member 3 is connected to the reciprocating screw rod 31 and drives the reciprocating screw rod 31 to rotate. The push plate 32 is threadedly matched with the reciprocating screw rod 31 and slides against the inner wall of the cleaning tank 14. In order to reduce the influence of the rotation of the cleaning member 2 on the work of the cleaning assembly, The distance between the cleaning member 2 and the bottom of the cleaning tank 14 increases along the sliding direction of the push plate 32. The driving member 3 can be a motor. When the driving member 3 drives the reciprocating screw 31 to rotate, it drives the push plate 32 to slide against the bottom end surface of the cleaning tank 14, and promptly pushes the impurities deposited at the bottom of the cleaning tank 14 into the receiving tank 16. In order to reduce the disturbance of the cleaning liquid in the receiving tank 16 when the cleaning member 2 rotates, the receiving tank 16 can be set to a smaller width to reduce the diffusion range of impurities in the receiving tank 16, and a movable plate can be set at the receiving tank 16 to facilitate regular disassembly of the movable plate and cleaning of impurities inside the receiving tank 16.

[0043] In addition, there are a small amount of larger impurities that cannot pass through the through hole of the cleaning member 2 and will be retained in the cleaning member 2. Such impurities can be cleaned by regularly cleaning the cleaning member 2. Specifically, a drain groove 17 is provided on the machine body 1. The drain groove 17 is connected to the cleaning groove 14 through a drain port 143. The drain port 143 is located at the lower side of the feed port 141. When the feed end of the cleaning member 2 is at the lowest position, it is connected to the drain port 143. The drain port 143 is movably provided with a blocking block 25. In actual operation, the cleaning part 2 can be flushed when the equipment is stopped, so that the feed end of the cleaning part 2 is opposite to the sewage outlet 143, and the discharge end of the cleaning part 2 is opposite to the discharge outlet 142, and the blocking block 25 is opened to allow large-volume impurities to slide to the feed end of the cleaning part 2 and enter the sewage tank 17 through the sewage outlet 143. In order to promote the movement of impurities to the feed end of the cleaning part 2, water or cleaning liquid can also be injected into the cleaning part 2 from the discharge end of the cleaning part 2 to flush the inside of the cleaning part 2.

[0044] The integrated plastic crushing and cleaning device provided by the present invention facilitates continuous cleaning of broken plastic fragments, improves the cleaning efficiency of the fragments, and during the cleaning process, both light fragments and heavy fragments are fully contacted with the cleaning liquid, thereby improving the cleaning intensity of the fragments, ensuring the cleaning effect of the fragments, and facilitating the collection operation of the fragments after cleaning.
