2. Description of the Related Art With the stabilization of social life, people can afford to appreciate and enjoy various things. The recent pet boom is one of the manifestations of this phenomenon, and dogs and cats are kept in many households regardless of location conditions such as urban areas and county areas. However, the daily worries of households that keep such pet animals are problems of manure, and various pet manure disposal products are lined up in supermarkets and department stores. A typical manure treatment product is paving sand to be spread in a pet toilet, and when roughly classifying what has been provided so far, it consists of mere crushed stone and artificially granulated ones, for example. , Paper fiber, crushed bentonite, kneaded material of bentonite and zeolite powder, and kneaded material of fibrous material and zeolite powder are each granulated.

In the case of mere crushed stone, of course, the stone itself is not water-soluble, so once it has clung to the feces, it cannot be flushed into the toilet together with the feces. , If you have a garden or a vacant lot, you can bury it in the soil, but in most cases, it is thrown away along with other garbage, and a new amount of sand is added to reduce the amount of waste. Is doing And once every few days, the whole sand covered with urine is washed and dried many times, and then reused.However, the smell once soaked does not easily disappear, so the economic advantage is Even if there is, the problem remains in removing the malodor, and the places where it can be used are limited.

On the other hand, the artificially granulated product has a deodorizing effect as well as its part is appropriately solidified when the manure is applied, and the solidified part is removed to remove it together with other garbage. If it is treated with water, or if it is water-soluble, it is possible to treat it by flushing it in the toilet, etc., which is considerably more expensive than using the above crushed stone, Since it is excellent in handleability and deodorizing effect, it has been adopted by a considerable number of pet lovers. However, even with this type of hard sand, if the treatment is delayed, the hardened part loses moisture and collapses from the surrounding area, making it difficult to distinguish it from unspoiled soft sand.
When the pet again uses it, there is a problem that the feet are soiled with the already spread soil, and there is a problem in that the deodorizing effect is also hindered.

Therefore, in the present invention, a completely new type of laying sand for treating excrement is developed in which the laid sand portion once exposed to manure is discolored so that it can be clearly distinguished from other portions. , And finally succeeded in realizing an economically advantageous discolored paving sand and a method for producing the same, and the constitution thereof will be described in detail below.

[0006]

The pet sand excrement treating sand of the present invention basically has the following constitution. That is, from a solid core containing clay containing fine silica sand powder as a main component, a zeolite core, a water absorbing agent, and a methylene blue powder as a pigment, which are kneaded and solidified respectively, and a solidification accelerator covering the entire surface of the core. And a coloring material adhered to or permeated to the outer surface of the surface coating layer, for use in treating pet excrement and urine.

As the clay which is the main component of the granular core, it is convenient to separate and collect the clay containing about 15% in the silica sand produced in large quantities in Oishida area of Yamagata prefecture. Is. This contains a large amount of halloysite having a high water content, which is a type of clay for clay, and has excellent granulation properties, which is extremely convenient for molding the granular core body of the present invention. The fine silica sand particles to be mixed with the clay are the process of separating and recovering the clay from the silica sand, that is, the silica sand coarse particles are first separated by a mechanical classifier (for example, an Akins classifier, etc.), and then the sedimentation classifier (for example, , Sand corn, etc.) and a mechanical classifier (eg, rotary classifier) to separate finer silica sand particles, when adjusting the degree of separation, adjust the mixture ratio to an appropriate range. .

This adjustment affects the disintegration property by water after granulation and the shape retention strength after commercialization, and the increase in the mixing ratio improves the disintegration property, but decreases the shape retention strength. After being commercialized as paving sand, there is a risk that it will easily collapse. Therefore, the optimum range for guaranteeing the shape retention strength that does not reduce the commercial value and facilitating the disintegration due to excrement water and solidifying into a lump of dango will cause some difference depending on the size of the granular material. Through 50
If the content is in the range of wt%, preferably 40 wt%, the intended purpose can be achieved over the entire range of the particles having different sizes.

Zeolite powder is added to the above-mentioned clay, which is a main component as a deodorizing material for adsorbing offensive odors and bad odors emitted from pet manure, and it may be natural or artificial. An appropriate amount considering the deodorizing effect and economic efficiency, that is, an amount in the range of about 5% by weight with respect to the clay mixed with fine silica sand particles as the main component is adopted as the optimum value, and greatly exceeds this value. Not only affects the shape retention strength, but naturally becomes expensive per unit price, which is contrary to the object of the present invention. At about 1% by weight or 2% by weight, it becomes inexpensive. However, the deodorizing effect cannot be exhibited.

As the water absorbing agent, aerated stone powder, especially perlite powder (325 #) is effective. As an example of the ratio of these mixed substances, for example, about 10 to 15% by weight ratio with respect to the zeolite powder may be mixed. Methylene blue used as a pigment is a harmless white powder that develops an extremely bright blue color with a predetermined amount of water.
Clay containing fine silica sand particles, which is the main component, contains about 100 g per cubic meter of rice, and a granular core having a diameter of about 2 mm contains a small amount of 2 to 3 methylene blue particles mixed in one core. Doing so is enough. It is desirable that the granular core body formed in this manner is formed as irregular and irregularly shaped granular material having a diameter of approximately 1 to 5 mm in order to stabilize the strut of the pet's foot.

The surface coating layer functions as a solidification accelerator for the granular core made of the above-mentioned materials, and is a relatively water-absorbing bentonite powder, especially a sodium bentonite powder (250 #, for example, Kunimine brand name). (Kunigel) is suitable and is formed by adhering it to the entire surface of the granular core body by the water content contained in the granular core body added at the time of granulation or by applying a melted product.
The colorant makes up the white color of bentonite, which is the surface coating layer, and helps methylene blue powder mixed inside the granular core to float up its blue color when it is colored by manure water. It fulfills its function,
In addition to white, colors such as yellow and light green are suitable, and are attached or impregnated into the surface coating layer and contained.

Hereinafter, a method for producing the spread sand for treating pet excrement of the present invention will be described.

[Invention Concerning Manufacturing Method] The manufacturing method of the present invention basically comprises the following first to fourth steps. [First step] The main component is clay containing fine silica sand powder, a proper amount of zeolite powder, a water absorbing agent, and methylene blue as a pigment are mixed and homogenized, and methylene blue is regulated so as not to develop color on a flat granulator. A process of forming a large amount of granular cores by rotating and kneading while spraying water in a spray form. The adjustment of the granulation state in this step is performed by adjusting the tilt angle of the rotary plate of the flat granulator while considering the balance between the water spraying ratio to be regulated and the silica sand fine powder mixing ratio in the main component. It is possible to efficiently manufacture a granular core body of a size that does not lose its shape.

[Second Step] The entire surface of the granular core body is regulated by adding a solidification accelerator powder and rotating and mixing the granular core body, which is formed in a large amount by controlling water content, into a rotary mixer. A step of forming a surface coating layer made of a solidification accelerator.
In this step, the water contained in the granular core when water is regulated and sprinkled in the first step naturally proceeds so that the introduced solidification accelerator adsorbs the water. Depending on the amount of water to be solidified, the adhesion amount of the sodium-based bentonite powder may change, so that the amount of the solidified accelerator and the particle size of the solid core may be changed depending on the amount of water contained in the granular core. Consider to be.

[Third step] A large amount of the granular material having the surface coating layer formed thereon is again rotated and mixed in a rotary mixer, and a colorant having a desired color is sprinkled to form a white surface coating. A step of coloring the layer surface in a predetermined color. The coloring agent sprayed in this step is such that the surface coating layer adsorbs the moisture contained in the granular core and is in a substantially homogeneous wet state as a whole (however, the outer surface of the granular core is wet in the stage produced in the first step). The water content of the surface coating layer is much smaller than that in the state), and the colorant adheres to the water contained in the surface coating layer and partially dissolves, and part of it penetrates into the surface coating layer. In such a state, the entire surface is colored almost uniformly.

[Fourth step] A step of drying them with hot air to obtain a slightly fired state. The hot air is kept at a temperature of about 100 ° C. and the whole is uniformly dried, and only the surface coating layer is slightly fired (if the whole granules are completely fired, it will be difficult to disintegrate with water). It is implemented until is realized.

[0015]

[Other Related Manufacturing Method] The manufacturing method of the present invention having the above-mentioned steps as a basic constitution can be further improved as follows. [First step] The main component is clay containing fine silica sand powder, and an appropriate amount of zeolite powder, a water absorbing agent, and methylene blue as a pigment are mixed and homogenized, and methylene blue is regulated so as not to develop color on a flat granulator. A process of forming a large amount of granular cores by rotating and kneading while spraying water in a spray form. This step is exactly the same as the above-mentioned basic production method of the present invention. Rotate and knead while spraying an appropriate amount carefully in a spray state on a flat granulator so that the pigment methylene blue does not develop color. Is a step of forming a large amount of amorphous granular cores.

[Second Step] A granular core formed in a large amount by controlling the water content is put into a rotary mixer, and the solidified accelerator powder which has already been colored is added and rotated and mixed.
A step of forming a colored surface coating layer made of a solidification accelerator on the entire surface of the granular core. The solidification accelerator powder used in this step is different from that in the above-described basic manufacturing method (that is, the bentonite dough which is the solidification accelerator remains as it is). It is a colored product obtained by solidifying a bentonite solution into a lump and mixing a desired colorant at the stage of the bentonite solution, and therefore, the coloring step of the third step in the above basic production method. However, in this related manufacturing method, the steps are simultaneously performed in the step of forming the surface coating layer. The other means for forming the surface coating layer on the granular core is exactly the same as the second step in the basic manufacturing method described above.

[Third step] A step of drying them by hot air and making them into a slightly fired state, which is the above-mentioned basic production method of the bed sand for treating pet manure treatment by the first to third steps. Is composed of the first to fourth steps, while the coloring step of the third step is completed in the second step at the same time.

[0018]

[Operation] The bed sand for pet excrement treatment of pets of the present invention having the above-mentioned configuration has a good shape retention property because the granular core is composed of a main component in which an appropriate amount of silica sand fine powder is mixed in clay. In addition to being formed inexpensively as a whole, inside it, a zeolite with an excellent deodorizing effect, a water-absorbing agent that quickly draws water in feces and urine into the granular core, and coloring by water Is formed by combining methylene blue, which is an extremely high pigment, and is coated with a solidification accelerator with a colored surface coating layer to provide excellent shapeability and shape retention.

As a result, once the feces and urine of the pet has been exposed to some amount of water, the water-absorbing agent quickly functions to suck the water into the granular core through the individual surface solidification accelerators, and the color development by the water of methylene blue occurs. In this process, the solidification accelerator, which is the surface coating layer, collapses due to the infiltrated water and flows out, adhering the particulates to each other, and making the dung-covered portion dung, It loses its own color due to the bright blue color of methylene blue, which emanates from the inside, and discolors the entire dango-like portion into a vivid blue color. Try to distinguish it from the sand part at a glance. Even if this dango-shaped portion begins to dry temporarily, the bright blue color developed by methylene blue is stopped as it is, and its contour (that is, the place where the manure is applied and the place where it is not) are like the spread sand before. There is no risk of making the boundary with) unclear.

On the other hand, as for the unpleasant odor of manure, the zeolite contained in the granular core 1 in an optimum amount of the minimum necessary amount is surely adsorbed, and the bad odor from the manure is filled around. It will work like no. Therefore, the pet buyer should be able to reliably remove only the soiled part of the spread sand at his convenience and at any time, and only if it is necessary to remove it and replenish the lost spread sand. , It is possible to always use only new paving sand in the pet toilet.

In addition, in the production method, the amount of fine silica sand powder in the clay is adjusted to an appropriate amount, and the amount of water is regulated to a value that does not cause the color reaction of methylene blue.
In the process of forming the surface coating layer immediately after that, if there is no mistake in the operation to suck as much water as possible from the granulated core inside the granulated core, the conventional flat granulator and rotary mixer In a further improved manufacturing method, which is a manufacturing method capable of manufacturing a combination of and, the working step of finally producing colored and makeup spread sand is more than that of the basic manufacturing method of the present invention. It is also possible to realize it by reducing one process.

[0022]

[Working] Therefore, the pet sand excrement treatment pet pet of the present invention can remove the soil dust of the soiled portion only by taking the condition that the previous ones are hardened in a dango shape as a guide. Is the dirty sand part,
As a guideline for the removal of the spread sand part, which becomes dry and crumbles and mixes with the unspoiled spread sand part to make it indistinguishable, a bright blue color that does not change even after drying Since it is possible to implement it at any time with certainty, it is less likely that the pet's feet will be soiled and the floor of the building will be unclean, and above all, the dirty sand part will be It has an excellent characteristic that it hardly remains in the toilet for a long time and becomes a source of offensive odor and makes the environment in the building unpleasant.

Moreover, not only the fine silica sand powder in the clay, which is the main component, contributes to the shape-retaining property, but also plays the role of a bulking agent. It is possible to provide it as an inexpensive one, and the conventional one had a problem in that the more effective one, the more expensive and widely spread. Since it can solve the difficulties of, many pet lovers can use it without worrying about the expense burden so much, especially in urban areas, which are not blessed with a living environment. It is expected that it will be highly evaluated as a very large feature for people who keep pets at home.

On the other hand, even in the method of manufacturing the spread sand of the present invention, even though the new spread sand has a new function, consideration is given to the balance between the mixing ratio of the silica sand fine powder and the moisture adjusting condition. As long as care is not taken in a small part, etc., it is possible to manufacture by using the machines and devices that have been used up until now, and in combination with the above-mentioned reasons for the material, the sand of this invention can be provided at low cost. In this respect, this manufacturing method is an extremely advantageous manufacturing method. In particular, in the further improved manufacturing method, the number of manufacturing steps can be reduced by one, so that the effect becomes even more remarkable.

As described above, the present invention has a very useful function as a bed sand for treating excrement of pets, and can be provided at a low cost. It is expected that it will make a great contribution to many pet enthusiasts, who have been provided with smooth sand, but are still in a difficult situation to treat manure. . It is a chart.
