Paper machine for used paper recycling apparatus

Abstract

To present a paper machine for a used paper recycling apparatus small enough to be installed in a room of small shop or the like, friendly to the environment, low in running cost, and high in confidentiality. The paper machine includes a paper making process unit for manufacturing wet paper from slurry pulp suspension sent from the pulp making section in preceding process, a drying process unit for drying and regenerating the wet paper manufactured in the paper making process unit, and a calender roll unit for calendering the dry paper dried in the drying process unit, in which the calender roll unit is disposed adjacently to the downstream side position of the drying process unit, and calenders the dry paper discharged from the drying process unit by rolling and pressing from both face and back sides.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a paper machine for a used paper recycling apparatus, and more particularly to a paper machine for a used paper recycling apparatus of furniture size installed at the site of origin of used paper, for recycling and processing into reusable paper at the site without discarding the generated used paper, in which the slurry pulp suspension is manufactured into wet paper.[0003]2. Description of the Related Art[0004]Used paper of various types occurs not only in government offices or private companies, but also in daily life or general household. Used paper is usually discarded, incinerated, or disposed as refuse.[0005]On the other hand, in the global concern about effective use of limited resources on earth, various technologies have been developed to regenerate and reuse the used paper being disposed and discarded so far.[0006]Such used paper recycling technologies are mostly installed in paper mak...

Benefits of technology

[0033](1) The used paper recycling apparatus is a small and simple structure including, in an apparatus case of furniture size, a pulp making section for manufacturing used paper pulp by macerating and mashing used paper, and a paper making section (the machine) for manufacturing recycled paper by making the used paper pulp manufactured in the pulp making section, and therefore without discarding the used paper, the used paper is recycled and reused at the same site of origin, and disposal of used paper is reduced, and refuse problems can be solved, and the limited resources can be utilized effectively.

[0034]Hitherto, because of confidential problems, recycling of used paper has not been promoted, but since the used paper can be recycled and reused at the same site of origin, effects of effective utilization of resources are outstanding.

[0035](2) At the site of origin of used paper, a compact used paper recycling system having a same function as large scale system installed in paper making plant or used paper recycling plant is installed, and used paper can be recycled continuously in a closed circuit in a small shop or general household, and refuse collection and transportation expenses and in

Problems solved by technology

For recycling of used paper, a tremendous manual labor is needed for collecting used paper, and used paper collection involves various problems, such as mixing of foreign matter by garbage collectors, defective classification due to lack of knowledge about used paper recycling, and entry of harmful objects, and if used paper is collected, in order to recycle by 100 percent, final checking by specialists and cleaning works are needed.

On the other hand, confidential documents are not easily recycled and are mostly
