Problems solved by technology

However, due to the direct use of wind sorting in this method, the wind resistance generated in the system is relatively large, so the energy consumption is large, which does not conform to the principle of resource conservation, and the sorted plastics are often mixed with many impurities, resulting in The quality of the obtained products is low, so how to improve the efficiency of recycling and sorting has become a hot topic of downward research

Embodiment Construction

[0011] The present invention provides a multi-stage sorting system for waste plastics, comprising a material conveyor belt 10, an accelerating conveyor belt 20, a triangular conveyor belt 30 and a collection bin, and the material conveying direction of the material conveyor belt 10, the accelerating conveyor belt 20, and the triangular conveyor belt 30 Same, the feed end of described acceleration conveyor belt 20 is correspondingly arranged below the discharge end of material conveyor belt 10, the feed end of described triangular conveyor belt 30 is lower than the discharge end of acceleration conveyor belt 20, and the material conveyor belt 10 The speed of travel is less than the speed of acceleration of the conveyor belt 20, and the collection bins include at least two, the first collection bin 40 corresponds to the discharge end of the triangular conveyor belt 30, and the second collection bin 41 corresponds to the outlet of the acceleration conveyor belt 20. At the material...

Abstract

The invention relates to a waste plastic multi-stage sorting system and belongs to the technical field of waste recycling equipment. The system comprises a material conveyer belt, an acceleration conveyer belt, a triangular conveyer belt and at least two storage bins. The first storage bin corresponds to the discharge end of the triangular conveyer belt, and the second storage bin corresponds to the discharge end of the acceleration conveyer belt. A scraper is arranged below the discharge end of the acceleration conveyer belt. A gap is kept between the scraper and the acceleration conveyer belt. The lower end of the scraper is fixedly connected with an air baffle. The first storage bin is in an inverted conical structure, a filtering plate is disposed at the bottom of the first storage bin, an air draft channel is arranged below the filtering plate, and the tail end of the air draft channel is connected with an exhaust fan. By means of the technical scheme, impurities are removed through inertia firstly, a light plastic box is sucked through negative pressure to move at the bottom of the second storage bin, it is guaranteed that the light plastic box smoothly falls into the second storage bin, and the aim of removing plastic impurities is achieved. The system has beneficial technical effects.

Description

technical field [0001] The invention relates to a multi-stage sorting system for waste plastics, which belongs to the technical field of waste recycling equipment. Background technique [0002] Nowadays, with the acceleration of urban development, more and more wastes are generated in daily life. If effective recycling of these wastes becomes a top priority for environmental governance, among these wastes, especially plastic waste White pollution is the most serious. These plastics are generally made of polymer compounds such as polystyrene, polypropylene, and polyvinyl chloride. Due to their stable structure, they are difficult to degrade, resulting in serious environmental pollution. Most of the existing recycling methods adopt the catalytic cracking method to make chemical raw materials and fuels. This method will not cause secondary pollution, but it has high technical requirements, especially the recycling and sorting process and the catalytic process, which will direct...
