Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is applied to the floor of a breeding house for breeding livestock such as livestock breeding houses and poultry houses to treat excrement of livestock. The present invention relates to bedding powder that facilitates the removal of odor and facilitates the removal of odor.

[Background of the Invention]

In livestock farms for raising livestock, such as livestock sheds for raising cattle, horses, pigs, sheep, etc., which are raised for various purposes, and chicken sheds for raising chickens for egg collection and eating, livestock health Treatment of livestock excreta is the most important issue from the viewpoint of the environment.

From a functional perspective, the basics of treating this excrement are to eliminate the odor of excrement, and to efficiently remove or replace excrement or mats mixed with it.
It is necessary to be able to efficiently utilize excrement or rug mixed with it as fertilizer such as compost, and to consolidate it into three points. In addition to this, it is necessary to be inexpensive because it is used in large quantities.

[Conventional technology]

Then, various things have been invented or put into practical use as bed powder for feeding houses, and as an example thereof, in JP-A-60-197234, attention is paid to the water absorption of dehydrated ettringite, and the dehydrated ettringite is granulated. It is described that the crushed product is used as bed powder.

Further, in JP-A-58-23733, a porous granule made of an inorganic substance such as pumice or a clay substance, refractory clay, alumina, diatomaceous earth is used as a bed dust, and a deodorant is added to this. It is described to add.

Furthermore, Japanese Patent Publication No. 61-501907 discloses that a granular porous ceramic material is used as a bed powder for a rearing house.

[Problems to be Solved by the Invention]

Among the above-mentioned conventional techniques, the dehydrated ettringite described in JP-A-60-197234 has a weak deodorizing function because it only dries the farm using its water absorption, and also purchases ettringite. There is a problem that the cost increases due to the high cost and the need for dehydration processing using an electric furnace or the like.

Further, as described in JP-A-58-23733,
It has the advantage that the deodorant function can be improved by forming inorganic substances such as pumice, clay substances, refractory clay, alumina, diatomaceous earth, etc., and adding deodorant to them, but the problem of increased costs still remains .

Further, as described in JP-A-61-501907, in the structure in which the granular material made of the porous ceramic material is used as the spread powder, not only the material cost is required, but also the kiln must be used for firing. However, the processing cost also increases, and the cost problem is still unsolved in this case as well.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a spread powder satisfying all of the above-mentioned requirements (1) to (3).

[Means for solving problems]

In order to achieve this object, the present invention `` by pulverizing a porous blast furnace slag having innumerable fine pores, to form a powdery slag consisting of innumerable slag particles having a particle size adjusted to 0.1 to 5 mm, By immersing this powdery slag in a solution of the deodorant and drying it, the deodorant is impregnated and adsorbed in the fine pores of the slag particles. "

Granulated slag or expanded slag is suitable as the blast furnace slag used in the present invention. These are SiO ₂ , CaO, MgO, Al ₂ O ₃
Is contained as a main component, and is porous with innumerable fine pores. Then, by crushing the blast furnace slag of the material and sieving, the particle size is 0.1-5 mm (preferably
The spread powder of the present invention can be obtained by forming powdery slag composed of slag particles whose particle size is adjusted to 0.3 to 3 mm), immersing this in a solution of a deodorant, and drying.

On the other hand, as the deodorant of the present invention, for example, an extract substance from a natural plant such as green tea flavonoid which is an extract component of green tea, a sulfate such as ferrous sulfate or ascorbic acid, or a chemical synthesis represented by a mixture thereof is used. Product type,
In addition, activated carbon or the like is used. Of these, green tea flavonoids have excellent deodorizing effect on ammonia, amine, hydrogen sulfide, and nicotine, chemically synthesized products have excellent deodorizing effect on ammonia, and activated carbon has excellent deodorizing effect on mercaptan and hydrogen sulfide. ing.

In order to impregnate and adsorb the deodorant into the fine pores of the slag particles, the deodorant is dissolved in water or another solvent, immersed in this, and then dried. If the deodorant is insoluble, finely grind the deodorant, and then add the finely ground deodorant to a solution having a low viscosity such as water while stirring to form a suspension. By immersing the powdery slag in the suspension, the suspended matter (finely ground product of the deodorant) is impregnated into the fine pores of the slag particles, taken out and dried.

When it is necessary to increase the amount of the deodorant impregnated and adsorbed, the operation of the above [immersion-impregnation-drying] is repeated, the vacuum impregnation method is used, or the deodorant liquid is heated after heating the powdery slag. Just throw it in. It is also effective to promote impregnation and adsorption by applying a slight vibration with a vibrator during the immersion in the solution.

[Operation and effect of invention]

With the above configuration, the deodorant is impregnated and adsorbed in the fine pores of the slag particles, so that the slag particles have a strong deodorant function, by spreading the spread powder on the floor of the feeding house in an appropriate amount. It is possible to significantly reduce the bad odor in the rearing house.

In addition, by adjusting the particle size of the slag particles to be 0.1 to 5 mm, it is possible to prevent the deterioration of the environment due to scattering when spraying to the farm, and to improve soil when mixed with cultivated soil as fertilizer. It can be promoted and the deodorant function can be improved.

That is, according to the experiment of the inventor of the present application, when the particle size of the slag particles is smaller than 0.1 mm, not only does it scatter to the surroundings when the farm is sprayed, but the environment is deteriorated, and when mixed with cultivated soil. This will cause a phenomenon of solidifying the soil, and conversely, if the particle size exceeds 5 mm, not only the particle size composition of the soil is deteriorated, but also when the deodorant is impregnated, the solution becomes difficult to penetrate to the inside, The dipping work had to be repeated many times, which increased the effort.

On the other hand, as in the present invention, when the particle size is in the range of 0.1 to 5 mm, it is possible to spray the spread powder to the rearing house without scattering it, and the solidification phenomenon of the soil occurs when mixed with the cultivated soil. It does not deteriorate the particle size composition, and furthermore, when immersed in the solution of the deodorant, the solution quickly penetrates inside the slag particles, so that the desired deodorant function can be achieved without trouble. It came to be able to obtain.

In addition, the fact that the blast furnace slag has a soil-modifying property by alkalizing the soil and the fertilizer effect by the excrement of livestock can be combined to contribute to the soil fertilization.

And since blast furnace slag is a slag discharged in the iron making process, it is a waste material that was conventionally troubled with processing, so there is no material cost, and slag is crushed to remove deodorant. Since it is only impregnated and adsorbed and the processing is extremely simple, the manufacturing cost can be remarkably reduced as compared with the conventional spread powders.

As described in claim 2, when the particle diameter of the slag particles is set to 0.3 to 3 mm, it is possible to more reliably prevent the scattering when spreading the flour in the rearing house and to further deteriorate the particle size composition of the soil. The deodorant solution can be surely prevented, and the deodorant solution can easily penetrate into the slag particles, so that the deodorant can be more reliably adsorbed, and thus the function as the spread powder can be further improved. .

By the way, while the odor source such as the odor of livestock excrement or metabolic waste is a odor that is a combination of various odors such as ammonia odor,
Since synthetic deodorants generally have a narrow range of deodorants, it may not be possible to reliably eliminate the odor inside the housing.

On the other hand, when green tea flavonoids are used as a deodorant as described in claim 3, the green tea flavonoids have a wide range of applications, and therefore, there is an advantage that the odor in the feeding house can be effectively eliminated.

〔Example〕

SiO ₂ , CaO, MgO, Al ₂ O ₃ by sieving the porous granulated slag as a main component, 15 kg powder slag consisting of porous slag particles adjusted to a particle size of 0.3 ~ 5 mm Created.

On the other hand, in a solution diluted 50 times the green tea flavonoid stock solution,
The powdery slag with the adjusted particle size was put in a fine basket, soaked for 5 minutes, taken out, put in a drying room, and dried by passing hot air at 80 ° C. for 8 hours to obtain a bed powder for a rearing house of the present invention. .

And the following test was done about this spread powder.

Width 500 mm, length 1500 mm, depth 6 formed from baked painted iron plate
Spread the spreading powder on the bottom of the 0 mm saucer to an average thickness of 10 mm,
On top of that, 3 kg of chicken feces immediately after excretion were scattered. The saucer thus constructed was placed on the floor of the test chamber having an internal volume of about 30 m ³ , and the chamber was sealed.

A sensory test for changes in odor was conducted by 5 testers having normal olfaction. Immediately before the test room was closed, everyone felt a foul odor. One hour later, when entering the test room, the odor was reduced and a deodorizing effect was recognized. Five hours after that, when entering the test room, the odor was further reduced by half. Furthermore, after entering the test room 24 hours later, there was almost no odor, and it was confirmed that the deodorizing effect lasted for a long time.
