Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sheets, films, bags, bottles, etc., which are disposed of as general wastes such as household garbage and are disposed of as business wastes from factories, supermarkets, department stores and companies. The present invention relates to a plant for increasing the bulk specific gravity of a waste sheet material configured to form a granular material having a high bulk specific gravity from various waste sheet materials processed into various shapes with a relatively small thickness.

[0002]

2. Description of the Related Art In recent years, styrofoam discarded as general waste and business waste, and discarded processed into various shapes with a relatively thin thickness such as a sheet, a film, a bag, and a bottle. Plastic articles have been recycled as raw materials for plastics, processed into molded articles such as rods and piles, and used as raw materials for recycled solid fuels and recycled oils. In particular, the Packaging Recycling Law will be enforced in 2000, and interest in recycling is increasing. In order to promote the reuse of such resources, plastic waste has been separated and collectively collected. If there are many containers such as bottles,
The average specific gravity of these waste plastic articles is,
It was very small, about 0.03 to 0.07.

[0003] Transporting with the above specific gravity not only has poor transport efficiency and adversely affects the cost of recycled products, but is also difficult to handle in the next step and transport on a conveyor or the like. there were. Attempts to cut and mass transport were also made, but only slightly increased transport volume.
Only by cutting, the bulk specific gravity (weight per volume including voids) is still small, and a significant improvement in transport efficiency cannot be achieved. In addition, when cut, there is a risk that it will be scattered by wind during transportation or storage, and management is difficult.

[0004] Therefore, a melting device called an agglomerated granulator has been developed. The device rotates a plurality of horizontal blades at high speed at the bottom in a cylindrical container, puts plastic waste into it, cuts it, and melts it by frictional heat. It was supplied and finally turned into granules.

[0005]

However, waste sheet materials are often piled up outdoors and temporarily stored until they are treated, and may be contaminated with earth and sand, wet or wet by rain or snow. In some cases, metal crowns and staples remain attached. These contaminants deteriorate the quality of the molded product and cause abrasion of equipment and devices, particularly the molding die and the perforated plate, and need to be removed. Further, the above-mentioned granulator has a small processing capacity in a batch system and a high running cost. In addition, plastic materials are difficult to operate because the melting temperature differs depending on the material, and a certain amount of molten material cannot be obtained, or operation becomes impossible if the operating method corresponding to plastic materials is not well known. there were.

The present invention has been proposed in view of the above, and is intended to continuously form various waste sheet materials such as a sheet, a film, a bag, and a bottle into granules having a large bulk specific gravity. Mass processing to go, even if wet or wet,
Even if processing is started with a metal crown or staples nail attached, or with soil and sand mixed in, they are removed in the processing process, and depending on the purpose of reuse, for each material or for several types It is an object of the present invention to provide a plant capable of continuously producing granules capable of performing granulation with stable quality, facilitating transportation by a conveyor or the like and reducing storage space, and increasing the bulk specific gravity of a waste sheet material.

[0007]

In order to achieve the above object, a plant for increasing the bulk specific gravity of a waste sheet material according to the first aspect of the present invention includes a sheet, film, bag, bottle and the like. A crusher that crushes various waste sheet materials with a specific gravity difference that have been processed into various shapes with a relatively small thickness, and foreign matter that removes material other than waste sheet materials such as earth and sand and metal caps from the crushed material as foreign matter A removal sorter, a dryer that dries the crushed material from which foreign matter has been removed, a wind sorter that sorts into a light-weight object carried by wind using the specific gravity difference and a falling heavy object, and from the wind sorter It is characterized by comprising a cyclone separator for collecting lightweight materials conveyed by wind power, and a consolidation molding machine for consolidating the lightweight materials collected by the cyclone separator to obtain a molded product having a higher bulk specific gravity.

Is configured to be conveyed by wind from the second wind separator to the second cyclone separator and collected there, so that the heavy load is further separated by wind with a stronger wind force than the wind force of the first wind separator. 2
By collecting the crushed and light-weight material, which is slightly heavier than the light-weight material sorted by the first wind separator by the cyclone separator, the crushed and light-weight material can be sent to the granulator, thereby reducing the amount of waste and increasing the amount of recycling.

Sheet material pieces continuously pulverized by a pulverizer such as a crusher are transported aerodynamically to the cyclone separator in a simple and continuous manner to prevent rain and foreign matter from being mixed, even if they are far apart. After collection, it is transported to a foreign matter removal and sorting machine.
