Description

Recycling waste sorting device {ASSORTING APPARATUS FOR RECYCLED PRODUCT}

The present invention relates to a recycling waste sorting apparatus, and more particularly, to a recycling waste sorting apparatus that can be quickly and easily separated and collected from the mixed waste transporting lightweight plastic waste and metal waste.

In general, mixed wastes discharged from homes and factories are collected in garbage dumps, and cans, bottles, plastics, and the like are sorted and recycled.

In order to improve the recycling efficiency of the waste, it is important to separate the recyclable waste by type from the collected waste. Among the wastes, light plastic wastes such as waste vinyl tend to stick to other wastes, increasing the difficulty of waste sorting. When the plastic waste is buried, it is not decomposed to cause soil pollution, and when incinerated, there is a problem of generating harmful gases such as dioxins, and it is preferable to recycle the waste. Plastic waste can be recycled through a recycling process such as solid fuelization.

With the recent increase in the use of plastic films and the like for product packaging, plastic waste accounts for a large amount of waste that is separately collected at home, and the proportion of plastic waste sorting in waste sorting is increasing. Plastic wastes are light in weight but bulky and not easy to sort.

In addition, ropes and nets, which occupy most of the coastal waste generated from the coast, are lightweight plastic waste such as waste vinyl, and they may be recycled through the same process as waste vinyl.

Conventionally, lightweight plastic waste sorting, such as waste vinyl, has been mostly done by hand. In the manual sorting of light plastic waste, it is common for the worker to pick up the light plastic waste from the mixed waste transported by a tool such as a hook on both sides of the conveyor. This manual sorting method has a problem that requires a lot of labor.

In addition, in the conventional sorting method using trommel, since the bulky plastic waste is mixed with other wastes such as bottles and cans, the sorting rate is lowered and a secondary sorting operation is required.

On the other hand, metal wastes such as food and beverage cans, butane gas cans, spray cans, etc., when recycled, can greatly reduce the cost compared to processing ore ores into commercial products, so the recycling ratio is higher than other wastes. Metal waste must also be sorted from other mixed wastes before it can be recycled, so an effective sorting method is required for recycling.
