Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and in particular to a waste recycling device for plastic products. Background Technology

[0002] Plastic products are widely used in today's society, but their non-biodegradable nature places a heavy pollution burden on the environment. More than 70% of plastics are discarded indiscriminately, causing so-called "white pollution" and severely damaging the ecological system. Faced with the environmental problems caused by plastic waste, strengthening the recycling and reuse of these wastes has become a major task that urgently needs to be addressed globally. Recycling plastic products can not only effectively reduce environmental pollution, but also save valuable resources and promote the achievement of sustainable development goals. Through recycling and reuse, we can transform waste plastic products into new raw materials or products, thereby reducing our dependence on and exploitation of original natural resources.

[0033] In one optional embodiment of the present invention, such as Figure 7 As shown, there are three shredding blades 13, each of which has a different length. They are arranged in order of increasing length, thereby increasing the contact area between the plastic and the material, thus gradually increasing the shredding density and enabling the plastic to be shredded step by step.

[0034] Working principle: In use, plastic waste is conveyed through the feeding rack 1, which has an inclined surface and can move slowly through a vibration mechanism. Stepper motor I8 is started, driving turntable 10 to rotate. Through the transmission shaft I9, the two turntables 10 on both sides can rotate synchronously, thereby causing the eccentric shaft on the turntable 10 to drive the vibrating plate 7 to vibrate up and down. When the plastic waste passes through the baffle I2, it will be squeezed to the middle to prevent the mixture from falling directly into the storage box 5. When it passes through the baffle II3, the jet nozzle 4 on the baffle II3 sprays high-pressure air, which can blow the relatively lighter plastic into the storage box 5, while heavy metals and soil impurities will continue to slide down and fall to the collection point.

[0035] When a certain amount of plastic products accumulate in the storage box 5, the partition 6 is pulled outward, causing the plastic products to fall into the pipe 11. Then the partition 6 is closed, and it is opened again after it is full again, forming intermittent feeding. The stepper motor II 14 is started, and the transmission shaft II 12 is driven to rotate through the reduction gearbox, thereby causing the crushing blade 13 to rotate. The plastic products will pass through the crushing blade 13 from short to long in sequence, and the degree of crushing will become stronger and stronger, and the crushing will be more uniform.

[0036] After the pulverized debris falls into the cleaning tank 15, water is injected through the water inlet 16. Then, stepper motor III 17 starts, driving the driven gear 18 to rotate, which in turn rotates the internal stirring wheel 20. The stirring wheel 20 agitates the water in the cleaning tank 15, thus cleaning the debris. After cleaning, stepper motor IV 21 starts, driving the rack 22 to slide upwards. The rack 22 drives the strainer plate 23 to slide upwards. The strainer plate 23 slides within a groove on the inner wall of the cleaning tank 15, and the debris on the strainer plate 23... The debris will be carried up, and the water will leak down. As it slides to the top, it will be forced to turn as the chute turns, causing the drain plate 23 to tilt and the debris to fall onto the discharge chute 19. As the drain plate 23 rises, it will catch the short shaft on the baffle plate Ⅲ 24, causing the baffle plate Ⅲ 24 to slide upward, thus exposing the drain outlet blocked by the baffle plate Ⅲ 24 and draining the sewage. When the drain plate 23 returns to its original position, the baffle plate Ⅲ 24 will block the drain outlet again, while the water inlet 16 continues to fill with water, waiting for the next cleaning.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
