Description

Technical Field

[0001] This utility model relates to the field of mineral water bottle recycling technology, specifically a screening device for recycling PET mineral water bottles that is easy to clean. Background Technology

[0002] Recycled PET mineral water bottles can be processed through physical or chemical methods to be remade into various plastic products. Physical methods include steps such as sorting, crushing, washing, dehydration, and drying, ultimately producing recycled polyethylene terephthalate products.

[0003] Chinese patent discloses a mineral water bottle recycling device, publication number CN209095807U, which includes a recycling device and a crushing device. The recycling device includes a collection bucket, a buckle, a side door, a top cover, a connecting rod, a metal mesh, and a drain pipe. A water bottle containing mineral water is placed in the collection bucket. Due to gravity, the bottle falls downwards and lands on a roller. The outer surface of the roller has crushing blades. A motor is electrically connected to an external power source. The motor's rotation drives the drive gear, which in turn drives the driven gear, causing the two rollers to rotate relative to each other. The crushing blades surrounding the outer surface of the rollers cut the mineral water bottle open. The water inside the bottle flows out and falls to the bottom of the collection bucket, while the crushed mineral water fragments slide into the left-side collection bucket due to the obstruction of the metal mesh. The collected mineral water can be used for watering plants, thus avoiding water waste.

[0004] However, it still has the following drawbacks: the device uses a motor to drive the shredder to rotate and shred the mineral water bottle, then collects the bottle fragments. However, the outer surface of the collected mineral water bottle may be covered with dirt, leaves, plastic, and foam. Therefore, the outer surface of the PET mineral water bottle must be cleaned before recycling. To address this problem, we propose a sieving device for recycling PET mineral water bottles that is easy to clean. Utility Model Content

The back of the second water pump inlet pipe is fixedly connected to the front of the cleaning tank. By setting up the second water pump, it is convenient to rinse the outer surface of the mineral water bottle with cleaning fluid.

[0012] A further improvement is that the cleaning unit also includes a water guide pipe and a solenoid valve. The back of the water guide pipe is fixedly connected to the front of the water tank, and the left end of the water guide pipe is fixedly connected to the outer surface of the inlet pipe of the second water pump. By setting the water guide pipe and the solenoid valve, it is convenient to reuse the water inside the water tank.

[0013] A further improvement is that the filter screen is located above the bottom end of the second water pump inlet pipe, and the outer surface of the filter screen is fixedly connected to the inner wall of the cleaning tank. By setting the filter screen, it is convenient to filter impurities.

[0014] A further improvement is that the filtration section also includes a filter box and a vertical rod. The outer surface of the top of the filter box slides through the bottom surface of the filter screen, and the top surface of the filter box is flush with the inner wall of the filter screen. By setting up the filter box, it is convenient to collect impurities.

The second water pump is started, spraying the cleaning solution inside the cleaning tank onto the outer surface of the bottle. The first water pump is then started, spraying clean water onto the outer surface of the bottle. After cleaning, the bottle is discharged to the right. Subsequently, the contents of the cleaning tank are... The wastewater is discharged from the main tank, and then the water in the clean water tank is introduced into the cleaning tank by the second water pump, and cleaning solution is added. By setting up a filter box and filter screen, the filter screen filters impurities, and the filter box collects impurities. By setting up a push plate, bottom rod, top rod, vertical rod and connecting rod, the vertical rod is pulled backward to make the push plate tilt, so that the bottom end of the push plate tilts up and the push plate moves backward. The vertical rod is pushed forward so that the front of the vertical rod contacts the back of the bottom rod, so that the push plate turns vertical. Then the push plate pushes the impurities into the filter box. Attached Figure Description
