Description

{SEPARATING SYSTEM FOR PITH AND LEAF AND BARK FROM CORN STALK}

The present invention relates to a separation system for separating the depth of the corn stalk (Pith), the outer leaves (Leaf) and the bark (Bark), and more particularly, the biggest obstacle when mass production of high-quality paper pulp An automatic separation system for separating an improved depth of corn stalk, stalk and shell to provide high-quality pulp production by providing a device for separating the depth of the corn stalk and the outer leaves and their debris, excluding the husk of the corn stalk.

In general, paper has been manufactured using wood pulp as the main raw material, but in countries with relatively insufficient wood resources, pulp has been produced using herbaceous plants such as straw, bagasse, and reed for a long time. However, the quality of pulp is very inferior because it is made at the level of small-scale domestic industries, and there are many difficulties in the paper manufacturing process such as poor dehydration.

In addition, due to the development of industrialization, the destruction of the environment is intensified, causing serious problems that threaten the survival of mankind, such as ecosystem changes and rapid climate change, as side effects such as climate warming.

In the case of Indonesia, a major producer of timber, these changes in environment are limiting logging of trees as part of an environmental protection policy, and Brazil is also suppressing logging.

This change not only raises the price of wood pulp, but also wars against securing pulp for paper manufacturing.

This global trend has become interested in the pulp resource of herbaceous plants and agricultural wastes that are relatively short in growth cycle and can be reproduced annually.

In particular, herbaceous plants have morphological and chemical properties very different from wood.

Although bast fibers and some herbaceous plants have longer lengths than wood pulp fibers, most herbaceous plants contain large amounts of thin or short flow cells compared to wood pulp.

As such, when used as a raw material for manufacturing paper, it has been difficult to commercialize due to poor dehydration and low strength properties, and has only been used as a raw material for producing low-grade paper in a low-developing country or a country that lacks wood resources.

Although their chemical properties have properties similar to broad-leaved trees, they generally show a low lignin content while a high hemicelluloses content.

Meanwhile, corn stalk is one of many agricultural wastes. They are discarded because they have no special purpose, except that some are used as feed. Therefore, attempts to recycle pulp from corn stalk can greatly help not only protect the environment but also improve farm household income through resource recycling of waste.

Particularly, the fiber length of corncob is somewhat longer than that of broad-leaved trees and has a thin characteristic, so it is expected to be difficult to secure the bulk of paper, but it is possible to partially improve the bulk problem through the whole extraction of hemicellulose. When replacing about 40% of wood pulp, it does not have a negative effect on paper quality, and it is much more advantageous than wood pulp when used for special purposes such as glassine paper.

In addition, the lignin content is very low compared to wood, and the hemicellulose content is high, so it has chemical properties suitable for papermaking.

The depth of the corn stalk is an inner tube part surrounded by a bundle of tubes arranged in a tubular shape, and is composed of very fine flow cells. It contains a large amount of silica, so if it is not separated from the corn stalk, it causes many problems to use as paper pulp. can do.

The fact that such a technique to separate the water depth has not been developed can be said to be the reason why corn sticks have not been widely used as a raw material for papermaking.

Particularly, if there are many flow cells with very small fiber size, dewatering is not good, so the production speed cannot be increased during paper manufacturing, and web breaks occur.

For this reason, even in China, where corn stalks are being mass-produced, they are limited to the production of low grade packaging paper and are only partially used.

The cornstalk shell means a part of the cornstalk, from which the water depth and the outer leaf part are removed from the shells, water depth, and outer leaves. And, only the skin part of the corncob is used for the production of corncob pulp.

When the pulp is manufactured using all of the husk, water depth, and outer leaves constituting the corncob, the pulp production efficiency is low compared to the consumption of chemicals during cooking. In addition, by containing a large amount of parenchyma cell fibers having a very short fiber length, dehydration property is poor, and strength may be low when producing paper using corncob pulp.

In addition, the depth and the outer leaves of the corn cob separated in addition to the corn cob shell can be used in a bio refinery process including the production of cellulose ethanol.

This means that it is possible to increase the industrial availability or recyclability of by-products while realizing corncob pulp.

In addition, the existing pretreatment device for removing the depth of corncob is going through a very complicated step of splitting the corncob in a certain direction, arranging it in a certain direction, and then squeezing it to widen it and scraping the depth from it. The productivity is low and the processing capacity is too low for use in the pulp mill, which needs to supply corn chips from the country.

As another method, after cutting and crushing the corncob, the foreign matter is first separated by the wind, and then, after hitting the crushed separated water and shell chips, the water is separated into a water depth chip and a peel chip. There is a method of separating a small sized water chip into a screen net as the screw is rotated with a screw in a circular cylinder, and finally separating the remaining peeled chips. It is difficult to separate the water depth and the shell by hitting all of the chips with the rotating hitting part.

In addition, the method of separating each particle by using a screw in a cylinder having a screen net is difficult to separate completely by depth and shell only by classifying the size, and even this separation is difficult to use only with the shell of a corn cob.

Therefore, there is a need to improve the method of manufacturing a cornstalk chip with a device for completely separating the water depth, outer leaves, and foreign matter except the cornstalk.
