ぺッ 卜の糞尿処理用敷き砂およびその製造方法 技術分野  TECHNICAL FIELD The present invention relates to litter for treating pet manure and its production method.
本発明は、 犬、 猫等ペッ トの糞尿処理用敷き砂の新規な構造とそ の製造方法に関するものであり、 糞尿によって固化すると同時に、 糞尿の水分を吸収した部分の敷き砂表面が発色して使用済みである こ とを確認できるよ う にした理想的なぺッ 卜の糞尿処理用敷き砂 と、 それを簡便且つ確実に製造する方法とを提供しょう とするもの である。  The present invention relates to a novel structure of a litter for treating manure of pets such as dogs and cats and a method for producing the litter. It is an object of the present invention to provide an ideal cut-out litter for treating urine and urine, and a method for easily and reliably producing the litter.
背景技術 Background art
社会生活の安定化と共に、 人々の間には様々なものを鑑賞し、 愛 玩する余裕がでてきている。 昨今のぺッ トブームもその現象の一つ の表れであって、 都市部、 郡部等といった立地条件に関係なく 、 多 く の家庭で犬、 猫が飼われている。 しかし、 このような愛玩動物を 飼う家庭の毎日の悩みが、 糞尿の問題であって、 スーパーゃデパー 卜には様々なぺッ 卜の糞尿処理用品が並べられている。 糞尿処理用 品と して代表的なものが、 ペッ ト用 トイ レに敷き詰める敷き砂であ り、 これまでに提供されているものを大別してみると、 単なる砕石 からなるものと、 人工的に粒状化したもの、 例えば、 紙繊維、 ベン 卜ナイ 卜破砕物、 ベン トナイ 卜 とゼォライ ト粉末との混練物や、 繊 維質材とゼォライ ト粉末との混練物等を夫々粒状化したものとの 2 通りのものが提供されている。  With the stabilization of social life, people can appreciate various things and can afford to pet. The recent pet boom is also a manifestation of this phenomenon, and dogs and cats are kept in many households regardless of the location conditions, such as in urban and rural areas. However, the problem of daily excrement in homes that keep such pets is the problem of excrement, and there are various types of excrement disposal products in the SuperDepartment. A typical example of manure processing products is the litter spread on pet toilets.The broad categories of litter provided so far include those made of mere crushed stones and those made artificially. Granulated, for example, paper fiber, crushed bentonite, kneaded mixture of bentonite and zeolite powder, kneaded mixture of fiber material and zeolite powder, etc. Are provided.
単なる砕石からなるものの場合には、 当然石自体が水溶性のもの でないこ とから、 一旦糞にまとわり付いてしまった以上、 それを糞 と共に便所に流してしまう という訳にはいかず、 庭や空き地のある 人であれば土の中に埋めてしまう こ ともできるが、 大抵の場合は他 のごみと一緒に捨ててしまい、 捨てて少なく なつた分量だけ新しい 敷き砂を加えるという処理の仕方をしている。 そして何日に一回か 1 は尿で汚れた敷き砂全体を何回も洗い流して乾燥させ、 再利用する という ことになるが、 一旦染み付いた臭いはなかなか抜け切らず、 したがって、 経済的な利点はあると しても、 悪臭除去の点で問題が 残り、 使用できる場所に制限を受けるこ とになる。 In the case of mere crushed stone, it is natural that the stone itself is not water-soluble, so once it has stuck to the dung, it cannot be washed away with the dung to the toilet. And people with vacant lots can be buried in the soil, but in most cases they are discarded together with other garbage, and only a small amount of new litter is added. You are. And once every day 1 means that the whole litter is washed, dried and reused many times, but the smell once permeated is hard to escape and therefore has economic benefits, Problems remain with regard to the removal of odors, which limits the places where they can be used.
5 これに対し、 人工造粒したものは、 翼尿がかかるとその部分だけ 適当に固まってしまう と共に、 脱臭効果が出るようにしたものであ り、 固まつた部分を取り除いて他のごみと一緒に処理してしまった り、 水溶性のものでは、 便所に流す等して処理するこ とを可能にす るものも開発され、 上記した碎石を使用する場合に比較し、 かなり 0 割高になってしまう ものの、 取り扱い性の点や脱臭効果の点で、 秀 れていることから、 かなりのペッ ト愛好家が採用するようになって きている。  5 On the other hand, in the artificially granulated product, when wing urine is applied, only that part is solidified properly and the deodorizing effect is obtained.The solid part is removed and other waste is removed. Some have been developed that can be treated together, or if they are water-soluble, they can be treated by flushing them into the toilet, etc. However, pet pet enthusiasts have come to adopt it because of its excellent handling and deodorizing effect.
ところが、 この固まるタイプの敷き砂も、 それらの処理が遅れて しまう と、 固まった部分が湿気を失って周辺から崩れ、 未だ汚れて5 いない敷き砂との見境を付け難く してしまって、 再度ぺッ 卜が用を 足す際に、 それら既に汚れている敷き砂で足を汚してしまう という 不都合が生じる外、 脱臭効果上からも支障を来すという問題を抱え ている。  However, if the processing of this hardening type of bed sand is delayed, the hardened part loses moisture and collapses from the surroundings, making it difficult to establish a relationship with the still dirty sand. In addition to the inconvenience that pets get their feet dirty with the already soiled litter when they use them, they also have a problem in that they have a deodorizing effect.
そこで、 この発明では、 一旦翼尿のかかってしまった敷き砂部分0 が、 他の部分から明瞭に区別できるよう、 水分で変色するようにし た全く新しいタイプの糞尿処理用の敷き砂の開発、 研究に取り組 み、 遂に経済的にも有利な変色する敷き砂およびその製造方法の実 現化に成功したものであり、 以下においてその構成を詳述するもの である。 発明の開示  In this invention, therefore, the development of a completely new type of litter for manure treatment, in which the litter 0 once covered with wing urine is discolored by moisture so that it can be clearly distinguished from other parts, After working on the research, we finally succeeded in realizing economically advantageous discolored litter and a method for producing the same, the details of which are described below.

The second step of forming a surface coating layer made of a color-enhanced singulation accelerator, the third step of drying the colored granules with hot air and slightly firing them, Or a method for producing a bed sand for treating manure in three steps. BEST MODE FOR CARRYING OUT THE INVENTION
この発明のぺッ 卜の糞尿処理用敷き砂は、 基本的に次のような構 成から成るものである。 即ち、 珪砂微粉末を含む粘土を主成分と し、 ゼォライ ト粉末、 吸水剤、 および顔料のメチレンブルー粉末を 夫々適量混練して個化した粒状芯体と、 該粒状芯体の表面全体を覆 う個化促進剤からなる表面被膜層と、 該表面被膜層の外表面に付着 もしくは浸透させた着色料とから成るぺッ 卜の糞尿処理用敷き砂と するものである。  The litter for treating manure according to the present invention basically has the following configuration. That is, a granular core composed mainly of clay containing fine silica sand powder, and kneaded with zeolite powder, a water-absorbing agent, and methylene blue powder of a pigment in appropriate amounts, respectively, and covers the entire surface of the granular core It is a litter for treating manure, which comprises a surface coating layer composed of an individualization accelerator and a coloring agent adhered or penetrated to the outer surface of the surface coating layer.
粒状芯体の主成分となる粘土には、 山形県大石田地区に多量に産 出する珪砂の中に約 1 5 %程含有している粘土を分離、 回収して採 用するようにすると好都合である。 これには、 陶土用粘土の一種で ある水分含有量の多いハロイサイ 卜が多く含まれ、 造粒性に秀れ、 この発明の粒状芯体を形成する上で極めて都合が良い。 粘土に混入 させる微細珪砂粒子は、 上記粘土を珪砂から分離、 回収する過程、 即ち、 機械的分級機 (例えば、 エーキンス分級機等) によ り、 先ず 珪砂粗粒を分離した上、 沈降分級機 (例えば、 サン ドコーン等) 、 そして、 機械的分級機 (例えば、 ロータ リ一分級機等) で更に微細 な珪砂粒子を分離させる過程で、 その分離具合を操作する際に、 そ の混入割合を適宣範囲に調整する。  For clay, which is the main component of the granular core, it is convenient to separate, collect, and use about 15% of the clay contained in the silica sand produced in large quantities in the Oishida area of Yamagata Prefecture. It is. It contains a lot of halloysite having a high water content, which is a kind of clay for pottery clay, has excellent granulation properties, and is extremely convenient in forming the granular core of the present invention. The fine silica sand particles to be mixed with the clay are separated from the silica sand by a process of separating and recovering the clay, that is, a mechanical classifier (for example, an Akins classifier) first separates coarse silica sand particles and then setstles the sedimentation classifier In the process of separating finer silica sand particles with a mechanical classifier (for example, a rotary classifier), the mixing ratio is controlled when the degree of separation is manipulated. Adjust to the appropriate range.
この調整は、 粒状化した後の水による崩壊性と商品化後の保形強 度とに影響し、 その混合割合が増えるこ とによって崩壊性が良く な る反面、 保形強度が低下し、 敷き砂として商品化した後で崩れやす いものとなる虞が出てく る。 したがって、 商品価値を落とさない程 度の保形強度を保証し、 糞尿水分によつて崩壊して一塊のダンゴ状 に固ま り易く する最適範囲は、 その粒状体の大きさによ り多少の差 を生ずるが、 大凡 2 0ないし 5 0重量%の範囲、 望ましく は 4 0重 量%となるようにすれば、 サイズの異なる粒状体全体に亘つて略所 期の目的が達成されるものとなる。 This adjustment affects the disintegration by water after granulation and the shape retention strength after commercialization, and as the mixing ratio increases, the disintegration improves, but the shape retention strength decreases. There is a risk that it will be easily broken after being commercialized as litter. Therefore, the optimal range of ensuring shape retention strength not to decrease the commercial value and facilitating disintegration by manure moisture and easy to solidify into a lump dango-like shape depends on the size of the granular material. A difference of about 20 to 50% by weight, preferably 40 times By setting the amount to be%, it is possible to substantially achieve the intended purpose throughout the granular materials having different sizes.
ゼォライ ト粉末は、 ぺッ 卜の糞尿から発散する異臭、 悪臭を吸着 する脱臭剤と して主成分である上記粘土に添加されるものであり、 天然のものでも人工のものでも勿論差し支えなく 、 その脱臭効果と 経済性とを加味した適量、 即ち、 主成分である微細珪砂粒子の混入 された粘土に対して約 5重量%前後の範囲となる量が最適値と して 採用され、 この値を大き く上回ると保形強度に影響を及ぼすだけで なく 、 当然単価的に高価なものとなってこの発明の目的に反するも のとなつてしまい、 また、 1重量%や 2重量%程度では、 安価なも のにはなるものの脱臭効果においてその機能を発揮し得ないものと なる。  Zeolite powder is added to the above-mentioned clay, which is the main component, as a deodorant that adsorbs off-flavors and odors emitted from pet manure, and it can be either natural or artificial. An appropriate amount considering its deodorizing effect and economic efficiency, that is, an amount that is in the range of about 5% by weight with respect to the clay containing fine silica sand particles as the main component is adopted as the optimum value. Exceeding this not only affects the shape retention strength, but also naturally increases the unit price, which is contrary to the purpose of the present invention. Although it is inexpensive, it does not have its function in deodorizing effect.
吸水剤と しては、 気泡状の石粉、 特にバーライ ト粉末 ( 3 2 5 # ) が有効である。 これら混入するものの割合の例と しては、 例え ば、 ゼォライ ト粉末との重量比で 1 0 ~ 1 5 %程度が混入されれば よい。 顔料と して採用するメチレンブルー粉末は、 所定の水分に よって極めて鮮やかな青色に発色する無害の白色粉体であって、 主 成分である微細珪砂粒子入り粘土 1立米当りに 1 0 0 g程度、 直径 2 m m前後の粒状芯体であればその 1個内にメチレンブルーの粉が 2〜 3個混入される程度の僅かな量が含まれるようにすれば十分で ある。 こ う して形成される粒状芯体は、 略 l〜 5 m m程度の直径か らなる不揃い、 不定型の粒状物と して形成するよ う にするのが、 ぺッ 卜の足の踏ん張りを安定させる上で望ま しい。  As a water-absorbing agent, foamed stone powder, particularly bar light powder (325 #) is effective. As an example of the ratio of these contaminants, for example, about 10 to 15% by weight of zeolite powder may be mixed. The methylene blue powder used as a pigment is a harmless white powder that develops a very vivid blue color with a certain amount of moisture, and the main component, clay containing fine silica sand particles, is about 100 g per cubic meter. In the case of a granular core having a diameter of about 2 mm, it is sufficient to include a small amount such that two or three methylene blue powders are mixed in one of the cores. The granular core formed in this way is formed as irregular, irregular shaped particles having a diameter of about l to 5 mm. Desirable for stabilization.
表面被膜層は、 上記した素材からなる粒状芯体の個化促進剤と し て機能させるもので、 比較的吸水性に富むベン トナイ ト粉末、 特に ナ ト リ ュウム系ベン トナイ ト粉末体 ( 2 5 0 #、 例えば商品名、 ク 二ミネのクニゲル) が適しており、 造粒時に加えた粒状芯体内の含 有水分によって粒状芯体表面全面に付着させるようにするか、 溶か したものを塗着するようにして形成される。 着色料は、 上記表面被 膜層であるベン トナイ トの白い色を化粧すると共に、 粒状芯体内部 に混入されているメチレンブルー粉末が、 糞尿水分で発色した際 に、 その青い色が浮き上がってく るのを助ける機能を果たすもの で、 白の他、 黄色、 薄緑色等の色が適しており、 表面被膜層に付着 あるいは含浸、 含有される。 The surface coating layer functions as an individualization accelerator for the granular core made of the above-mentioned material, and is a bentonite powder having a relatively high water absorption, particularly a sodium-based bentonite powder (2). 50 #, for example, trade name, Kunimine Kunigel) is suitable, and the moisture contained in the granulated core added during granulation should be applied to the entire surface of the granulated core or dissolved. It is formed in such a way as to apply the resulting material. The colorant makes up the white color of bentonite, which is the above surface coating layer, and when the methylene blue powder mixed inside the granular core develops color with manure, the blue color rises Suitable for white, yellow, light green, and other colors, it adheres to, impregnates, or is contained in the surface coating layer.
以下では、 この発明のぺヅ トの糞尿処理用敷き砂の製造方法につ いて説示する。 この発明の製造方法は、 以下の第 1 ないし 4工程か ら基本的に構成されるものである。  Hereinafter, the method for producing the litter for treating manure of the present invention will be described. The manufacturing method of the present invention basically includes the following first to fourth steps.
〈第 1工程〉  <First step>
珪砂微粉末を含む粘土を主成分と し、 ゼォライ ト粉末、 吸水剤、 および顔料のメチレンブルーを適量混入、 均質化した上、 平面型造 粒機の上でメチレンブルーが発色しないよう規制して噴霧状に散水 しながら回転、 混練することによって粒状芯体を多量に形成するェ 程。 この工程における造粒状態の調整は、 平面型造粒機の回転板 の傾斜角度を、 規制する散水割合と主成分内の珪砂微粉末混入割合 との兼ね合いを勘案しながら調整することによって、 所望する大き さの粒状芯体を型崩れさせずに効率よく製造するこ とができる。 〈第 2工程〉  The main component is clay containing fine silica sand powder, mixed with an appropriate amount of zeolite powder, water-absorbing agent, and pigment methylene blue, homogenized, and regulated to prevent methylene blue from coloring on a flat-bed granulator. A process of forming a large amount of granular core by rotating and kneading while spraying water. The adjustment of the granulation state in this step is desirably performed by adjusting the tilt angle of the rotating plate of the flat-bed granulator while taking into account the balance between the regulated watering ratio and the mixing ratio of the fine silica powder in the main component. It is possible to efficiently manufacture a granular core having a small size without causing it to lose its shape. <Second step>
水分を規制して多量に形成された粒状芯体を回転混合機に投入し た上、 個化促進剤粉末を加えて回転、 混合することによ り、 粒状芯 体の表面全体に個化促進剤からなる表面被膜層を形成する工程。 こ の工程では、 第 1工程で規制して散水された際に粒状芯体が含有す ることになる水分を、 投入された個化促進剤が吸着するような形で 自然に進行するものであり、 含有する水分量によって個化促進剤、 具体的にはナト リ ユウム系ベン トナイ ト粉末体の付着量が変わる可 能性があることから、 粒状芯体が含有する水分量に応じた最適な量 と粒度の個化促進剤となるよう配慮する。 〈第 3工程〉 A large amount of granular core formed by regulating the water content is put into a rotary mixer, and the individualization accelerator powder is added to the mixture to rotate and mix, thereby promoting individualization over the entire surface of the granular core. Forming a surface coating layer made of an agent. In this step, the water that will be contained in the granular core when regulated and sprinkled in the first step naturally proceeds in such a way that the added individualization accelerator adsorbs. There is a possibility that the adhesion amount of the individualization accelerator, specifically the sodium bentonite powder, may vary depending on the amount of water contained, so it is optimal according to the amount of water contained in the granular core. Care should be taken to be an individualization accelerator with an appropriate amount and particle size. <Third step>
表面被膜層が形成された多量の粒状体を、 再び回転混合機の中で 回転、 混合しながら、 所望する色の着色料を散布するこ とによ り、 白色の表面被膜層表面を所定通りの色に着色する工程。 この工程に おいて散布される着色料は、 表面被膜層が、 粒状芯体の含有水分を 吸着して全体が略均質な湿潤状態 (ただし、 第 1工程で製造された 段階の粒状芯体外表面の湿潤状態よ り遥かに水分量は少ない。 ) に なるのを待って使用されるこ とによ り、 表面被膜層が含有する水分 に着色料が付着して部分的に溶け出し、 その一部が表面被膜層に浸 透するような状態となって、 表面全体が略均質に着色されるもので ある。  A large amount of the granular material on which the surface coating layer is formed is again rotated and mixed in a rotary mixer, and a desired color is sprinkled with the colorant, so that the surface of the white surface coating layer is as prescribed. The step of coloring in the color of The colorant sprayed in this process is such that the surface coating layer absorbs the moisture contained in the granular core and is almost uniformly wet in its entirety (however, the outer surface of the granular core in the stage produced in the first step) The water content is much lower than that of the wet state.) When used after waiting for the color to adhere, the coloring agent adheres to the water contained in the surface coating layer and partially dissolves. The part is penetrated into the surface coating layer, and the entire surface is colored substantially uniformly.
〈第 4工程〉  <Fourth step>
熱風によってそれらを乾燥させ、 やや焼成状とする工程。 熱風 は、 約 1 0 0 °C程度の温度に保って全体が均質に乾燥され、 表面被 膜層だけがやや焼成されたよ う な状態 (粒状体全体が完全に焼成 されてしま う と水で崩壊され難く なる) が実現されるまで実施す る。  Drying them with hot air to make them slightly baked. The hot air is kept at a temperature of about 100 ° C and dried as a whole, and the surface is coated with water as if only the surface coating layer was slightly fired. Until it is difficult to collapse).
上記のような工程を基本的な構成とするこの発明の製造方法は、 更に次のような改良された製造方法とするこ とができる。  The manufacturing method of the present invention having the above-described steps as a basic configuration can be further improved as follows.
〈第 1工程〉  <First step>
珪砂微粉末を含む粘土を主成分と し、 ゼォライ ト粉末、 吸水剤、 および顔料のメチレンブルーを適量混入、 均質化した上、 平面型造 粒機の上でメチレンブルーが発色しないよう規制して噴霧状に散水 しながら回転、 混練するこ とによって粒状芯体を多量に形成するェ 程。 この工程は、 上記した基本的なこの発明の製造方法と全く 同じ であり、 平面型造粒機の上で顔料のメチレンブルーが発色しない程 度に噴霧状に注意深く 適量を散水しながら回転、 混練するこ と に よって不定形の粒状芯体を多量に形成する工程である。 〈第 2工程〉 A main component is clay containing fine silica sand powder, mixed with an appropriate amount of zeolite powder, a water-absorbing agent, and pigment methylene blue, homogenized, and regulated to prevent methylene blue from developing color on a flat-bed granulator. A process in which a large amount of granular core is formed by rotating and kneading while spraying water. This process is exactly the same as the above-mentioned basic manufacturing method of the present invention, and the mixture is carefully rotated and kneaded while spraying an appropriate amount of water on a flat granulator so that methylene blue as a pigment does not develop color. This is a step of forming a large amount of irregular-shaped granular cores. <Second step>
水分を規制して多量に形成された粒状芯体を回転混合機に投入し た上、 既に着色された個化促進剤粉末を加えて回転、 混合するこ と によ り、 粒状芯体の表面全体に個化促進剤からなる着色された表面 被膜層を形成する工程。 この工程において採用される個化促進剤粉 末は、 上記した基本的な製造方法におけるそれ (即ち、 個化促進剤 であるベントナイ トの生地のまま) とは違え、 個化促進剤粉末を作 る前の段階、 即ちベン トナイ 卜溶液を固めて塊状とする、 そのベン トナイ 卜溶液の段階で所望の着色料を混入してしまう こ とによって 得られる着色されたものであり、 したがって、 上記基本的な製造方 法における第 3工程の着色工程が、 この関連する製造方法では表面 被膜層を形成する工程で同時に実施されることになる。 その他の粒 状芯体に表面被膜層を形成する手段は、 上記した基本的な製造方法 における第 2工程と全く 同様である。  The granular core formed in a large amount by controlling the water content is put into a rotary mixer, and the already colored individualization accelerator powder is added and rotated and mixed to form a surface of the granular core. A step of forming a colored surface coating layer composed entirely of an individualization accelerator. The powder of the individualization accelerator used in this step is different from that in the above-mentioned basic manufacturing method (that is, the material of the bentonite which is the individualization accelerator), and the powder of the individualization accelerator is produced. The bentonite solution is solidified to form a block, and the desired colorant is mixed in the bentonite solution stage. In the related manufacturing method, the third coloring step in the conventional manufacturing method is performed simultaneously with the step of forming the surface coating layer. The means for forming the surface coating layer on the other granular cores is exactly the same as the second step in the above-described basic manufacturing method.
〈第 3工程〉  <Third step>
熱風によってそれらを乾燥させ、 やや焼成状とする工程  Drying them with hot air to make them slightly baked
以上第 1 ないし 3工程によるぺッ 卜の糞尿処理用敷き砂の製造方 法であって、 先の基本的な製造方法が第 1 ないし 4工程からなるの に対して、 その中の第 3工程の着色工程が、 第 2工程において同時 に完了してしまうようにした点に特徴を有するものである。  As described above, the method for producing the litter for treating manure of the cuts in the first to third steps is described above. The basic production method is comprised of the first to fourth steps, whereas the third step is included therein. This is characterized in that the coloring step is completed in the second step at the same time.
以上のような構成から成るこの発明のぺッ 卜の糞尿処理用敷き砂 は、 その粒状芯体が、 粘土に適量の珪砂微粉末を混入した主成分か らなるものとして保形性を良く すると共に、 全体として安価に形成 されるようにした上、 その内部には、 脱臭効果に秀れたゼォライ ト と、 糞尿内の水分を速やかに粒状芯体内に引き込む吸水剤、 そして 、 水分による発色性が極めて高い顔料のメチレンブルーが組み合わ されてなるものに形成され、 それらを着色された表面被膜層で個化 促進剤コーティ ングして整形性ならびに保形性に秀れたものと して レヽる。 The litter for treating manure according to the present invention having the above-described structure improves the shape retention property by assuming that the granular core is composed of a main component obtained by mixing an appropriate amount of fine silica sand powder in clay. In addition, Zeolite, which has excellent deodorizing effect, a water-absorbing agent that quickly pulls moisture from manure into the granular core, and the color development due to moisture Is formed by combining pigments with extremely high methylene blue, and they are coated with a colored surface coating layer to improve the shapeability and shape retention by coating with an individualization accelerator. Reply
その結果、 一旦ぺッ 卜の糞尿がかかって多少と も水分を受ける と、 個々の表面個化促進剤を通して吸水剤が逸早く それらの水分を 粒状芯体内に吸引するよう機能してメチレンブルーの水分による発 色を促すこ とになり、 この過程で表面被膜層である個化促進剤が、 浸透してく る水分で崩壊状となって流れ出して粒状体相互を接着さ せ、 糞尿のかかった部分をダンゴ化させながら、 内部から吹き出し てく るように発色するメチレンブルーの鮮やかな青色で自らの色を 失い、 ダンゴ化した部分全体を鮮やかな青色に変色させてしまい、 他の元々着色されている表面被膜層のままの敷き砂部分と一目で区 別されるようにする。 このダンゴ状となった部分は、 仮令乾燥し始 めてもメチレンブルーで発色した鮮やかな青色をそのまま止め、 従 前までの敷き砂のよ う に、 乾燥と共にその輪郭 (即ち、 糞尿がか かった所とそうでない所との境目) を不明瞭なものと してしま う虞 がない。  As a result, once the excrement is applied and some water is received, the water-absorbing agent functions to quickly suction the water into the granular core through the individual surface singulation accelerator, and the water from the methylene blue causes In this process, the individualization accelerator, which is a surface coating layer, breaks down due to the permeating water and flows out to adhere the granules to each other, and the part where manure is applied is promoted. It loses its own color with the vivid blue of methylene blue, which develops as it blows out from the inside while being dangod, causing the entire dangodated part to turn vivid blue, and other originally colored surface coatings At a glance, it is distinguished from the floor sand as it is. This dango-shaped part, even if it started to dry temporarily, stopped the vivid blue color developed in methylene blue, and as with the conventional sand, its outline (that is, excrement was excreted) as it dried. There is no danger of obscuring the boundary between places and places that are not.
一方、 糞尿の嫌な匂いは、 粒状芯体 1 の中に最小限必要限度の最 適な量で配合されているゼォライ 卜が確実に吸着して、 糞尿からの 悪臭が辺りに充満してしまわないように機能するこ とになる。 した がって、 ペッ トの飼い主は、 自分の都合に合わせ、 何時でも確実に 敷き砂の中の汚れた部分だけを確実に除去でき、 除去して少なく なった分の敷き砂を補充するようにしさえすれば、 ペッ ト用 トイ レ の中の敷き砂は、 常に新しい敷き砂だけにしておく こ とが可能にな る。  On the other hand, the unpleasant smell of manure is absorbed by the zeolite, which is mixed in the granular core 1 in the minimum and optimal amount, and the odor from manure is filled around. Function as if it were not. Therefore, pet owners should be able to remove only the soiled part of the litter at any time, at their own convenience, and to replenish the reduced litter. It is possible to always keep only the new litter in the pet toilet.
しかも、 その製造方法は、 粘土内の珪砂微粉末を適量に調整し、 その水分量がメチレンブルーの発色反応を起すこ とのない値のもの に規制すると共に、 直後の表面被膜層を形成する工程で、 造粒され た粒状芯体内の水分をできるだけ吸引してしまう ようにした操作さ え間違う こ とがなければ、 十分従前までの平面型造粒機と回転混合 機とを組み合わせた製造が可能になる製造方法であって、 更に改良 された製造方法においては、 最終的に着色されて化粧した敷き砂を 製造する作業工程が、 この発明の基本的な製造方法よ り も 1工程少 なく して実現することを可能にしている。 In addition, the production method involves adjusting the amount of fine silica sand in the clay to an appropriate amount, regulating the water content to a value that does not cause a methylene blue color reaction, and forming a surface coating layer immediately after the process. In order to remove the water inside the granulated core as much as possible, if there is no mistake, the mixing with the conventional flat granulator will be sufficient. In a further improved manufacturing method, the operation step of finally producing a colored and decorated litter is the basic manufacturing method of the present invention. This makes it possible to achieve this in less than one process.
したがって、 この発明のペッ トの糞尿処理用敷き砂は、 従前まで のものがダンゴ状に固まつている状態だけを目安にしてしか汚れた 部分の敷き砂の除去ができず、 実際には汚れている敷き砂部分であ りながら、 時間経過と共に乾燥して崩れて、 汚されていない敷き砂 部分に混ざり合って判別ができなく なつてしまう敷き砂部分の除去 を、 乾燥しても変わることのない鮮やかな青色へ変色した部分を目 安にして確実に何時でも実施可能とするものであることから、 ぺッ トの足を汚してしまって建物の床を不潔にしてしまう ようなこ と力5 少なく なると共に、 何よ り も汚れた敷き砂部分が、 ぺッ 卜用 トイ レ 内に何時までも残り続けて悪臭の発生源となり、 建物内の環境を不 快なものにしてしまう ということが殆どなく なるという秀れた特徴 を発揮し得るものとなっている。 Therefore, the litter for treating manure of the pet of the present invention can only remove the litter of the soiled portion with reference to the state in which the conventional litter is solidly adhered in a dango-like manner. The removal of the bed sand that has dried and collapsed with the passage of time and mixed with the unsoiled bed sand becomes impossible to determine even if it is dried. Since it can be implemented at any time by using the bright blue discolored area as a guide, it is possible to make pet feet dirty and make the building floor unclean. (5) As the amount decreases, the most unclean sand will remain in the toilet for a long time and become a source of foul odors, making the environment inside the building unpleasant. Is almost gone It has become a thing capable of exhibiting the cormorants Xiu features.
しかも、 主成分である粘土内の珪砂微粉末が保形性に寄与するだ けでなく、 増量剤の役目も果たすことになつて、 ゼォライ トや顔料 等を採用してはいるものの、 全体的に安価なものとして提供するこ とが可能であり、 従前までのこの種のものが効果的なものほど高価 になって広く普及する点で問題を抱えていたが、 この発明のもので は、 それらの難点を解消し得るものとなっているこ とから、 多くの ぺッ ト愛好家が経費の負担をそれほど気にせず、 常時使用すること ができることになり、 特に都市部のように住居環境に恵まれていな い家庭においてぺッ トを飼っている人々に対しては、 非常に大きな 特徴として高く評価されることが予想される。  In addition, the fine silica sand powder in the clay, which is the main component, not only contributes to shape retention, but also serves as a bulking agent, and although zeolite and pigments are used, overall However, there was a problem in that this kind of prior art was more effective and became more expensive and spread widely. Since these difficulties can be solved, many pet enthusiasts will be able to use the system at all times without worrying about the burden of expenses, especially in residential environments such as urban areas. It is expected that those who have pets in underprivileged families will be highly valued as a very significant feature.
—方、 この発明の敷き砂の製造方法も、 新たな機能が付加された 新規な敷き砂となっているにも係わらず、 珪砂微粉末の混合割合と 水分調整具合との兼ね合いに対する配慮等、 僅かな部分で注意を怠 らない限り 、 略従前までの機械、 装置を採用して製造が可能であ り、 上記した素材上の理由と相俟って、 この発明の敷き砂を安価に 提供する上で、 この製造方法は、 極めて有利な製造方法となってい る。 特に、 更に改良された製造方法では、 製造工程が 1工程少なく できるこ とからその効果は更に一層顕著なものとなる。 On the other hand, the production method of the spread sand according to the present invention is not limited to a new spread sand having a new function. Unless attention is paid to the slightest part, such as consideration for the balance with the moisture adjustment condition, it is possible to manufacture using almost the same machines and equipment as before, and in conjunction with the above-mentioned material reasons. In order to provide the litter of the present invention at low cost, this production method is an extremely advantageous production method. In particular, the effect of the further improved manufacturing method becomes even more remarkable since the number of manufacturing steps can be reduced by one.
叙上の如く 、 この発明は、 ペッ トの糞尿処理用敷き砂と して極め て有用な機能を兼備し、 しかも安価に提供するこ とが可能になるも のであるこ どから、 ペッ トブームの中で様々な敷き砂が提供されて はいるものの、 未だ糞尿処理に苦慮せざるを得ない状態に置かれて いる多く のペッ ト愛好家に対して、 大いに寄与するものとなるこ と が予想されるものである。  As described above, the present invention has an extremely useful function as a litter for treating pet manure, and can be provided at a low cost. Is expected to be a significant contributor to many pet enthusiasts who still have to struggle with manure disposal, although various types of litter are provided. Things.
