Description

Select apparatus of plastics of use for recycling of resins

The present invention relates to a size of recyclable mixed recyclables and a sorting device capable of separating and separating resins from recycled products. More specifically, the mixed recyclables in which initial foreign substances and the like are transported are transported through a multi-stage size selection conveyor, and the size of the recycled products is large. It is to be sorted according to ,, medium, and small, and glass bottles and synthetic resin containers contained among large, medium, and small sized recycled products are sequentially put into a wind sorter into which compressed air is injected by wind means. As the synthetic resin container is scattered by the compressed air of the wind means, it is distributed and discharged to the branched glass bottle distribution and the synthetic resin container distribution at a distance from the wind means depending on the difference in specific gravity. The present invention relates to a separating and separating device for a resin of a recycled product capable of increasing efficiency and separating high-purity synthetic resins because other materials are not stone.

In general, when recyclable items are collected, they can be sorted by type such as metal, non-ferrous metal, plastic, and glass, and furthermore, recycling efficiency can be increased only by sorting and sorting the selected recyclable items by color.

When sorting recyclables, there are parts that can be automated, and there are parts that are made manually by nature. The parts that can be automated are mainly used for sorting by size or metal sorting, and plastic and glass and non-ferrous metal sorting work and color sorting work are mainly sorted by hand. In addition, the efficiency of recycling of recyclable products depends on the performance of the devices installed in the sections where these sorting processes are automated and automatically progress.

However, in the prior art, most of the sorting processes are performed by hand, and devices for sorting by size, that is, a separator, are composed of a vibration or drum screen type separator.

The vibration separator has to be inspected and cleaned from time to time due to severe wear of the guide bar and foreign matter phenomenon and double loading phenomenon, and it is difficult to replace the guide bar, resulting in reduced operation rate and safety accidents due to delay in working time. There is a risk, and since the guide bar is expensive, maintenance costs increase.

The drum screen separator has the inconvenience of frequently performing maintenance and replacement work due to frequent wear and tearing of the mesh, and when replacement, the operation rate decreases due to the long delay of screen replacement time, and the maintenance cost increases and maintenance or replacement work There are disadvantages such as the occurrence of safety accidents.

In particular, PET bottles are mainly used for large beverage containers due to their lightness and good moldability. Since these PET bottles do not rot well, there is a concern that the environment may be contaminated if discarded as they are, and since PET bottles are expensive synthetic resins, they are economically wasted when discarded.

Moreover, it is very difficult to collect resins among mixed recycled products, and furthermore, PET, PE, and PP resins among resins cannot be sorted out separately unless they are skilled, and can also be checked separately to collect and recycled. There is a problem with poor sex.
