Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling, in particular to a solid waste treatment device for recycling waste plastics. Background Art

[0002] Waste plastic recycling and solid waste treatment is a comprehensive, environmentally friendly approach involving the collection, sorting, processing, and reuse of discarded plastic products, aimed at reducing environmental pollution and promoting resource recycling. Modern society's increasing reliance on plastic products has led to a rapid increase in the amount of discarded plastic. Waste plastic recycling not only helps address this environmental issue but also effectively conserves natural resources. Waste plastic recycling and solid waste treatment is a systematic project that requires comprehensive measures, including reducing usage at the source, increasing recovery rates, and optimizing treatment methods. Through technological innovation and policy guidance, plastic waste can be effectively recycled and rendered harmless, thereby promoting the development of a circular economy and protecting the human environment.

[0003] However, during the use of some existing waste plastic recycling and solid waste treatment devices, the waste plastic recycling process usually includes multiple links such as transportation, crushing, and collection. These links often need to rely on different driving sources to perform tasks, resulting in excessive energy consumption. Because each link has its own energy consumption, and there may be waiting time when switching between different links, the overall energy cost is increased, and automatic unloading of the crushed material cannot be achieved. This means that the crushed material requires additional operations before entering the next processing step. Such manual or semi-automatic processes further reduce work efficiency, increase labor costs and potential operational errors. Therefore, in response to the above shortcomings, a waste plastic recycling and solid waste treatment device is proposed to solve the above problems. Utility Model Content

A protective frame 37 is fixedly attached to the rear side of the outer frame 1.

[0035] Working principle: When it is necessary to use the waste recycling device, the waste plastic can be put into the interior of the outer frame 1 through the drop port 32, and then the motor 2 can be started to drive the rotating shaft inside the roller conveyor 4 to rotate, and then the roller inside the roller conveyor 4 can be driven to rotate. At this time, the waste plastic can be transported, and at the same time, the water inside the water tank 25 is sucked into the interior of the circulation pipe 38 through the water pump 26, and sprayed out through the rotating nozzle 39. With the help of the rotation of the rotating nozzle 39, the water can be fully sprinkled on the surface of the waste plastic, so that the labels or attachments on the surface of the waste plastic can be cleaned, and the water can be dropped to the inner bottom side of the outer frame 1 through the gap between the rollers inside the roller conveyor 4. When the solids are trapped inside the outer frame 1, the wastewater will fall into the inside of the collection box 29 through the filter hole 30 for recycling, and the wastewater can be recycled to the inside of the water tank 25 through the water pump 26 by means of the suction pipe 27 connected to the inside of the collection box 29 to complete the recycling. The cleaned waste plastics will fall between the driven crushing roller 13 and the active crushing roller 12. At this time, the motor 2 drives the driving wheel 5 to rotate, which in turn drives the driven wheel 7 to rotate. As the driven wheel 7 rotates, the driving shaft 8 and the driving gear 9 can be driven to rotate, which in turn causes the driven shaft 10 and the driven gear 11 to rotate. At this time, the active crushing roller 12 and the driven crushing roller 13 can crush the waste plastics.

[0036] As the driving shaft 8 rotates, the cam 14 will be driven to make a circular motion, and the rotation of the cam 14 will cause the push plate 15 to be displaced by force. At this time, the sliding rod 16 will slide inside the fixed plate 18, and the spring 17 will be stretched. At this time, the crushed material can be pushed by the push plate 15 to the inside of the drop trough 20 and fall down, so that the collection frame can be placed at the bottom to recycle the waste at the bottom. The scraper 21 can be driven to slide inside the outer frame 1 by the manual sliding limit frame 22, so that the solid impurities inside the outer frame 1 can be pushed to the inside of the filter hole 30 and fall down, so that the impurities can be collected with the help of the waste collection frame.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
