Description

Technical Field

[0001] The utility model relates to a waste plastic recycling and cleaning device, belonging to the field of plastic processing. Background Art

[0002] Plastic is a high-molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants and colorants. When recycling discarded plastics, the waste plastics must first be cleaned to ensure that impurities and oil stains on the plastics will not affect the recycling of the plastics. Therefore, a cleaning device is required when recycling plastics.

[0003] At present, waste plastics have the following deficiencies when being recycled and cleaned:

[0004] When cleaning plastics, since the outer surface of waste plastics is easily sticky with oil, during the cleaning process, the cleaning liquid will be mixed with a large amount of oil. The cleaning mechanism is likely to smear the oil on the plastic again during cleaning. At the same time, after cleaning, a large amount of a mixture of cleaning liquid and oil will precipitate inside the device. When these mixtures are discharged from the device, they are easy to remain, and a large amount of oil will also be stuck to the inner wall of the device after being soaked in the mixture. In this way, the cleaning and maintenance work of the device after use requires a lot of manpower and material resources. Utility Model Content

[0035] When in use, first open the barrel cover 2, pour the waste plastic into the cleaning barrel 1, then pour an appropriate amount of cleaning liquid into the cleaning barrel 1, and then cover the barrel cover 2 after pouring it. Then, start the motor 4, the motor 4 drives the driving gear 5 to rotate, the driving gear 5 drives the outer gear ring 8 and the rotating column 7 to rotate horizontally, and the rotating column 7 rotates while driving a plurality of rotating shafts 11 to rotate horizontally. The rotating shaft 11 rotates horizontally while driving the driven bevel gear 12 at its end to rotate.

After the cleaning barrel 1 has been cleaned for a period of time, the cleaning liquid in the cleaning barrel 1 will carry a large amount of oil stains, which will be deposited on the filter plate 16. In this way, the cleaning liquid without oil stains can pass through the filter plate 16 to supply the water pump 23, so as to realize the circulation feeding action of the cleaning liquid.

[0037] During the above operation, a large amount of dirt will be deposited on the filter plate 16, and the rotating column 7 will drive the scraper 15 to rotate while rotating. The rotation of the scraper 15 will scrape the oil on the top of the filter plate 16 and push it into several mounting racks 20, and then the oil will fall into the collection rack 22. In this way, after the cleaning of the batch of waste plastics is completed, the several mounting racks 20 can be taken out from the mounting holes 17, thereby realizing the removal and cleaning of the mounting racks 20 and the collection racks 22.
