Description

Pulverizing device for papermaking

The present invention relates to a paper-based disintegration apparatus for disassembling collectively to recycle the waste paper, in particular, a cylindrical body installed on the ground, power means for transmitting power from one side of the upper body, and the power means It consists of a driving means driven by, and a blow chain of various forms for dismantling and dismantling the waste paper that is inserted into the main body by connecting a plurality of chains of the rotating body and the circular arc of the rotating body driven by the drive means in the main body; It relates to a papermaking disassembly device composed of a striking means.

In Korea, resources are absolutely scarce and the percentage of recycled areas is significantly higher than in other countries.

Therefore, energy and resource saving activities must be continuously carried out at the individual, corporate, national and global levels, and Korea is actively inducing resource recycling to overcome resource shortages.

In the paper industry, which consumes a lot of resources and energy, such as water and natural wood, among the various industrial activities in Korea, the development of new processes for waste paper recycling and water saving should be pursued by paper companies in terms of resource saving, energy saving and environmental protection. It is attracting attention as a task.

In particular, the recycling of waste paper can achieve the effect of saving resources and suppressing greenhouse gas emissions through forest protection through the use of natural pulp wood. In other words, the paper industry that recycles waste paper is an industry that is highly effective in terms of saving energy and natural forest resources, as well as in terms of eco-friendliness to suppress waste and carbon dioxide emissions.

However, although a large amount of waste is discharged from industrial sites and homes, it is not recovered for recycling for recycling, but is disposed of incinerated or landfilled. Such waste disposal is another cause of environmental pollution, and there is an increasing interest in recycling. In order to cope with this, the recycling industry for waste paper is gradually increasing.

The recovered waste paper is mixed with a large amount of water to decompose the waste paper through mechanical dissociation process, and the decomposed waste paper pulp is recycled by removing foreign substances and pulping the waste paper through the selection and beating process.

At this time, the dissociation process of waste paper should be carried out in order to perform a smooth dissociation and pulper process. The dissociation process is usually carried out by disposing waste paper and water in the grinding tank where the grinding blade rotates. And dissociation of the fiber is made.

In order to perform the pulp process of waste paper smoothly, fiber particles have to be separated in a thinner form by disassembling and dissociating waste paper in the dissociation process. In this case, the dissociation process is not easily performed due to damage of the grinding blade, or even if dissociation is performed, the dissociation process does not decompose to a desired size and thus remains undissociated and cannot be used as a raw material for the pulp process.

To solve this problem, the waste paper was dismantled through the grinding blade to dissociate several times until the desired size was dissipated, or the dissociation accelerator was used to smoothly dissociate. However, this has a disadvantage in that the production time of the process is increased and the productivity is lowered, and the production equipment is also increased to increase the production cost.
