Cleaning method and system for used paper recycling apparatus

Abstract

The invention presents a cleaning method and a cleaning method for realizing a used paper recycling apparatus of furniture size, being installed in a room of a small shop or general household, friendly to the environment, and low in running cost. In the cleaning system, the white water dewatered and collected in the paper making section is used as cleaning water, and circulated in the pulp making section and pulp concentration adjusting section, so that the pulp making section and pulp concentration adjusting section may be cleaned. As a result, used paper pulp remaining in the parts of apparatus sections can effective cleaned and removed, troubles due to drying of remaining used paper pulp can be avoided, such as sticking of valves and failure of pumps due to dried used paper pulp, and occurrence of error in concentration adjustment due to residual pulp may be prevented.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a cleaning method and a system for used paper recycling apparatus, and more particularly to a cleaning technology for cleaning the component part of the apparatus in 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.[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 maki...

AI Technical Summary

Benefits of technology

[0013]It is other object of the invention to present a cleaning technology for realizing a used paper recycling apparatus of furniture size to be installed not only in a large office, but also in a small shop or a room in general household, friendly to the environment and low in running cost, capable of preventing leak of confidential information, private information, and other information, and keeping a high confidentiality.

[0037]By contrast, according to the used paper recycling apparatus of the invention, the information printed on the used paper is not diffused outside of the closed system, and the resources can be utilized effectively.

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 incinerated, and the recycling rate is low.

This wet process shredder is a giant machine installed in a wide space, and it can be used only in a large office, and it is not suited to small office or general household.

If shredded chips may be used as material for recycled paper, processing is possible only in large recycling plant, and the recycling cost is high and it is not economical.
