Embodiment Construction

[0019] In the embodiment shown in Figures 1 to 4: the collected urban waste is first conveyed to the crusher by the medium component conveyor belt 1 with a partition, and the crusher feeding hopper 5 is under the output end of the medium component conveyor belt 1, The box body 6 of the crusher is installed with a transmission shaft 8 driven by a motor 7 and a crushing knife 9 mounted on the transmission shaft 8 . On the side wall of the body 6, and higher than the transmission shaft 8, its lower end is tooth-shaped and conflicts obliquely below the transmission shaft 8. When the crushing knife 9 rotates, it passes between the teeth, and the upper end of the spring support shaft 11 is equipped with an overload protection spring 12. It is hinged with the middle part of the bottom surface of the scraper 10, and its lower end passes through the protruding bracket 13 on the side wall of the box body 6, and can slide back and forth; 15 is opposite, and respectively connected with th...

Abstract

The invention relates to a method for separating the life plastic waste, and relative device, wherein it comprises that: transmitting waste, breaking waste and wind selecting. The invention is characterized in that: the wind selection uses two-stage wind selection, with screening, weight change, as waste transmission, waste breaking, first-stage wind selection, screening, weight change and second-stage wind selection. The light waste, via broken, first-stage wind selection and vibration screen will be transmitted to weight changer, to immerge and squeeze the plastic and paper, to change their specific weight; and the second-stage wind selection will separate them. The invention can effectively separate plastic and paper, with low cost.

Description

technical field [0001] The invention provides a sorting device for plastics of urban living garbage, which belongs to the technical field of sorting and recycling of urban living garbage. technical background [0002] Garbage contains a large amount of recyclable components. If comprehensive recycling is carried out, not only the processing process is complicated, but the number of equipment is large and the cost is high, but the recycling efficiency is not high. In recent years, plastics have been widely used in the packaging field due to their light weight, high strength, and corrosion resistance. With the continuous increase in the output and consumption of plastic packaging, the ensuing problem is the rapid increase in the content of waste plastics, and the phenomenon of "white pollution" caused by waste plastics is becoming more and more serious, which has become a social focus of public concern. If these waste plastics in the garbage can be recycled and turned into re...
