Problems solved by technology

[0009] However, this wet processing pulverizer is a large machine installed in a wide space, so it can only be used in a large office, not suitable for a small office or an ordinary home
Shreds, if used as recycled paper raw material, can only be processed in large recycling plants and are expensive and uneconomical to recycle

Embodiment 1

[0052] Figure 1-Figure 10 shows the waste paper recycling plant of the present invention, said waste paper recycling plant 1 is installed especially at the primary source of waste paper, which is used to manufacture recycled paper at the primary source without treating or throwing away waste paper UP, The waste paper UP includes confidential documents of government offices and private companies, private letters of ordinary households, and other used and unnecessary documents.

[0053] Such as Figure 10 As shown, the waste paper recycling facility 1 has a furniture-like size, that is, the waste paper recycling facility 1 is similar in size and shape to office equipment such as file racks, lockers, desks, copiers, or personal computers, and mainly includes such as figure 1 The pulping section 2, the pulping section 2, the pulping section 3, the papermaking section 4 and the control section 5 are shown, and also includes a cleaning system CS for cleaning these sections, espec...

Embodiment 2

[0183] Figure 11 and Figure 12 The preferred embodiment is shown, which is similar to the preferred embodiment 1, except that the structure of the concentration adjustment part 3 is modified, and the cleaning system CS associated therewith is also slightly modified.

[0184] That is to say, in the waste paper recycling system 1 of the preferred embodiment, the structure of the pulp concentration adjusting part 3 is mainly changed, so as to save water consumption and make the overall structure of the waste paper recycling device 1 more compact.

[0185] The pulp concentration adjustment part 3 in this preferred embodiment is designed to adjust the concentration of the separation part of the waste paper pulp UPP in the pulping part 2, which mainly includes a waste paper pulp separation part 301 and a concentration adjustment part 302, such as Figure 11 and Figure 12 shown.

[0186] Therefore, the concentration adjustment box 26 in the preferred embodiment 1 is used as a p...

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 makingsection 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

technical field [0001] The present invention relates to a cleaning method and system for a waste paper recycling plant, and more particularly to a cleaning technique for cleaning components of a waste paper recycling plant installed at an initial source of waste paper in a furniture-sized waste paper recycling plant, so that The waste paper recycling equipment described above is used to recycle and process waste paper into recycled paper on site without discarding the generated waste paper. Background technique [0002] Various types of waste paper are generated not only by government agencies or private companies, but also in daily life or ordinary households. This waste paper is usually discarded, incinerated and disposed of as waste. [0003] On the other hand, from the global need to effectively utilize limited resources on the earth, various technologies for regenerating and reusing the processed and discarded waste paper have been developed. [0004] These waste pape...
