Description

  The present invention relates to a deposit separation device, and in particular, separates deposits on the surface of glass, liquid crystal display, metals, plastics (hereinafter also simply referred to as “input”) to be reused, and removes them. The present invention relates to an apparatus for separating deposits used as a raw material for recycling such as glass, metal and plastic.

  When a metal such as tin is vapor-deposited on the back surface of the glass like a mirror or a glass coated with a paint is used as a recycling raw material, it is necessary to separate the glass coating. In recent years, a liquid crystal display in which a liquid crystal material is sandwiched between glass substrates is often used. In order to reuse the glass substrate, it is necessary to separate deposits other than glass, coatings, and vapor depositions. In the present specification and claims, the term “attachment” is used in a broad concept including a deposit and a deposit. The term “separation” also includes the concept of peeling and removal.

As a conventional technique for separating glass coatings, glass armoring attached to a rotating body in a drum is used to stir glass pieces so that the coatings are separated by friction between the glass. There is an apparatus (Patent Document 1).
