Description

  The present invention relates to an indoor-installed type document shredding for offices and the like including a pulper unit that breaks up used paper such as office documents to make a recycled pulp suspension, and a papermaking unit that produces recycled paper from the recycled pulp suspension. The present invention relates to a waste paper recycling apparatus for waste.

  In view of the fact that document shredder has not been sufficiently recycled in the past, if the document shredder is recycled to relatively low quality recycled paper such as toilet paper, the waste paper recycling process can be omitted and an apparatus By reducing the size and simplification of documents, it is possible to recycle document shredded waste in units of organizations such as companies, government offices, associations, housing estates, or local governments, saving resources and energy, and collecting used paper In order to reduce the time and labor required for the paper, the process of separating the waste paper shredded by a document shredding machine with a pulper equipped with a stirring means to regenerated pulp, and the disaggregated regenerated pulp is always gently stirred. And storing the regenerated pulp stored in an injection device having a pressure source and an injection hole, injecting the regenerated pulp from the injection device, through a pair of rollers A document comprising a step of spraying the fiber sheet of a papermaking apparatus having an endless fiber sheet movably attached to the fiber sheet to form a regenerated pulp into a sheet, and drying the regenerated pulp in the form of a sheet with a drying roller to make a paper. A method for recycling shredded waste paper has been proposed (see Patent Document 1).

  Further, the present applicant has proposed a waste paper recycling apparatus for shredded documents as shown in Patent Document 2 and Patent Document 3 in order to solve various problems in putting the above proposal into practical use.

  Since the waste paper recycling apparatus for document shredded waste described in Patent Document 2 and Patent Document 3 described above has a compact design that can be installed in a room such as a company office, the recycling of document shredded waste can be performed by companies, government offices, Document shredded waste that has been incinerated or landfilled can be recycled in a manner that can be carried out by each organizational unit such as a union, housing complex, or local public entity, saving resources and energy, and reducing the time and labor required for collecting recovered paper It can be reduced.

However, in the waste paper recycling apparatus for document shredding waste described in Patent Document 2 and Patent Document 3 described above, the color of the recycled pulp suspension is changed due to the influence of the toner of the printer or copying machine attached to the document shredding waste. As a result, there is a problem that recycled paper that is not so white is produced.
