Abstract

The invention provides a flexibly packaged waste plastic mixture sorting device, which comprises a feeding hopper, a vibratory feeding device, a conveying plate, a wind-driven blowing and floating device and a classified collection device, wherein the feeding hopper is arranged at the upper end of the vibratory feeding device, the conveying plate is connected with the lower end of the vibratory feeding device, and the wind-driven blowing and floating device is connected below the conveying plate. The invention is characterized in that the wind-driven blowing and floating device comprises a ventilating mesh, an electric fan, a wind-driven regulator and a wind direction regulating device, wherein the upward wind outlets of the electric fan are sequentially connected with the ventilating mesh through the wind-driven regulator and the wind direction regulating device, and the ventilating mesh is connected below the conveying plate; a variable-speed vibration device and a bed surface sorting device are additionally arranged; the output end of the variable-speed vibration device is connected with the bed surface sorting device; and the head end of the bed surface sorting device is connected with the ventilating mesh, and the tail end of the bed surface sorting device is connected with the classified collection device. Waste plastics output by the vibratory feeding device through the conveying plate fall on the ventilating mesh, then the waste plastics are blown to the vibratory bed surface sorting device through wind, and the waste plastics are collected into the classified collection device after being sorted. The invention has the advantages of strong universality and high sorting efficiency.

Description

technical field [0001] The invention provides a sorting device for a mixture of waste plastics in flexible packaging, which belongs to the technical field of sorting and recycling domestic waste plastics. technical background [0002] In recent years, plastics have been widely used in the packaging field due to their light weight, high strength, and corrosion resistance. According to statistics, in 2007, my country's production of plastics reached more than 30 million tons, and the production of flexible packaging plastics reached more than 10 million tons. If 30% of plastic products are recyclable plastics, my country's recyclable plastic waste is about 100 million tons per year. 9 million tons. Recycling and processing these waste plastics can not only reduce the consumption of petrochemical raw materials, but also the price advantage of recycled plastics is prominent, the benefits are obvious, and the market potential is great. Speeding up the recycling of waste plastics ...
