Description

Porous wood chip for livestock manure fermentation {WOOD CHIP FOR NIGHT-SOIL FERMENTATION}

The present invention relates to a porous wood chip for livestock manure fermentation, more specifically, in the manure fermentation process to fertilize livestock manure to be produced as a compost, to effectively absorb the moisture of the manure to be a great help in fermentation will be.

In recent years, farms and livestock farms raise livestock, but as they become more and more industrialized, the breeding volume increases, and as the breeding volume increases, the manure is also discharged in large quantities.

Manure discharged from these livestock is polluted if left untreated or dumped in sewers. Recently, a method of drying and fermenting manure and reusing it as compost has been developed.

As a treatment method for composting livestock manure from large livestock farms such as large livestock farms or pig farms, it is stored in storage tanks to be naturally fermented, forced dry fermentation with a warm fan, fermentation accelerator or moisture control agent, etc. The fermentation method is added, and the like is performed.

As such, most of the methods of fermentation drying use sawdust or wood chips as a water absorption medium.

The characteristic of sawdust is that when it is mixed with manure and put into the manure fermenter, the necessary procedures for fermentation process are processed like manure and most of it is consumed. In other words, it cannot be reused.

Wood chip (W) as shown in Figure 1 is cut thinly sprinkled like cutting the branches as a sputum mochi cut because the thin cutting is advantageous to absorb moisture only when the thickness is thin, which is extracted from fermented dried manure It is possible.

However, wood chips are used because of their reusability, but because they are thin and long, they can be repeatedly cut off and the air supply disappears. The disadvantage is that it does not meet sawdust.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, the main subject of the invention is to make a new type of porous woodchip used, but having a plurality of through-holes in the capillary absorption and osmotic pressure to easily moisture It is intended to be able to absorb, and on the other hand is not intended to be easily worn for a long time it is intended to be used repeatedly.

Characteristic configuration of the present invention for achieving the above object is to prepare a round cube of any size completed by cutting and trimming wood, after processing the fine holes from the surface of the cube inside, repeated at random intervals Holes in the X-axis direction and holes in the Y-axis direction which are finely drilled inward from the surface of the hexahedron but do not intersect the X-axis direction while being repeated at random intervals and into the surface of the hexahedron. The fine holes are processed to be formed to hold holes in the Z-axis direction which do not intersect the X-axis direction and the Y-axis direction while being repeatedly repeated at random intervals.

Hereinafter, the configuration and operation according to the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Example 1

1 shows a hexahedron 10 of a representative embodiment of the present invention, FIG. 2 is a cross sectional view thereof, and FIG. 3 is a partially enlarged cross sectional view thereof.

As shown in the drawings, the present invention forms a hexahedron 10 by processing the vertical and vertical heights of dry wood of the water absorbing type, but forms a plurality of fine holes in three directions.

That is, while processing the fine holes from the surface of the cube to the inside, the holes (h1) in the X-axis direction that is repeated at random intervals continuously, and the fine holes into the inside of the surface of the cube, at random intervals Holes (h2) in the Y-axis direction that are not repeated to the X-axis direction while being repeated repeatedly, and also processes the fine holes from the surface of the hexahedron into the inside, while repeating at random intervals and the X-axis and Y-axis direction The holes h3 in the Z-axis direction that do not intersect are formed.

In this case, the holes may be in various forms as shown in FIG. That is, it can be penetrated from one surface to the opposite surface, and can be formed only to a depth within 1/2 of the cube width without penetrating as shown below, and sometimes 1/2 of the cube width You can also form deep beyond.

And the corners and vertices of each round is rounded and mixed with manure, so that the edges are not destroyed as possible when entering the stirring device.

Example 2

5 is a porous wood chip according to another embodiment of the present invention, and has a spherical body 20.

This is completed by cutting and finishing wood, spherical body 20 having a diameter of an arbitrary size, the surface of the spherical body is characterized in that a plurality of fine holes (h4) toward the inside to have a radial arrangement. .

In this case, the holes h4 are preferably formed to a depth not reaching the center of the spherical body as shown in FIG. 6, and in some cases, the holes h4 are not easily arranged in a radial form but are easily manufactured by a multi-axis drilling machine. It can also be formed as holes parallel to each other in order to.

Example 3

7 shows a cylindrical wood chip 30 as a porous wood chip according to another embodiment of the present invention.

This is completed by cutting and trimming wood, and having a cylindrical shape having an arbitrary diameter and an arbitrary length. Here, the holes h5 processed in the cylindrical surface may be arranged in a radial shape, as shown in FIG. 8. It may also be a form parallel to each other.

Then, both end surfaces of the cylindrical body is formed in a hemispherical shape so that the edges are not destroyed as much as possible when entering the stirring device while being mixed with the manure.

Each of the embodiments of the present invention as described above is described in the form of easy to use and widely used in the first place, it can be made of other cubes, and of course, they will not be significantly out of the scope of the present invention. .

The operation according to each of the above embodiments will be described.

When the porous wood chips are put into the manure, the moisture of the manure is absorbed by the wood chips, and the absorption process takes place from the entire outer surface and from the hole (H).

That is, when the porous wood chip is mixed with manure, the particles of the manure do not enter the hole (H) of the porous wood chip. Therefore, the water contained in the manure around the numerous holes (H) formed in three directions is 1 by capillary action. Subsequently, they penetrate into these holes H, and the water entering these holes is absorbed into the wood one after another from the inner surface of the holes H due to the osmotic action of the wood particles.

In addition, the manure in contact with the outer surface is gradually absorbed into the outer surface due to the osmotic action of the wood particles.

In addition, the porous wood chip of the present invention is suitable for the growth of microorganisms in a number of holes (H) formed in three directions to help the fermentation.

As described above, when the porous wood chip absorbs moisture and the manure is fermented and dried, it is passed to the next process for producing manure as a fertilizer, that is, a packaging process, and extracts all the porous wood chips from the dried manure before. After collection, they are sent back to the process where the first porous woodchip was used for reuse in manure fermentation drying.

The porous wood chip of the present invention as described in detail above is processed into wood, but since the outer surface is manufactured in a round shape without corners, even when entering a device such as a manure stirrer conveyor, the corners are prevented from falling off easily. It has the advantage of not having a longer lifespan, which is advantageous for repeated reuse.

In addition, the surface as well as the holes inside the osmotic action and capillary action, respectively, by the absorption of moisture and microbial cultivation is helpful for the endorsement of manure.
