Description

排泄物処理材及びその製造方法Excrement disposal material and its manufacturing method
　本発明は、排泄物処理材及びその製造方法に関する。 The present invention relates to an excrement disposal material and a method for producing the same.
　従来の排泄物処理材としては、例えば特許文献１に記載されたものがある。同文献に記載された排泄物処理材は、低吸水性を有する複数の粒状体からなり、システムトイレにおいて使用される。システムトイレは、排泄された尿を受ける本体部（トレー）、及び本体部の内部空間を上部空間と下部空間とに区画する仕切部（簀子）を備えている。上部空間（仕切部上）には、上述の複数の粒状体が敷設されている。下部空間には、尿を吸収する吸水性シートが配設されている。仕切部には、尿を通過させる一方で、粒状体を通過させない貫通孔が形成されている。本体部に排泄された尿は、粒状体どうしの隙間を通り抜けた後、仕切部の貫通孔を通じて上部空間から下部空間へと移動する。 Examples of conventional excrement disposal materials include those described in Patent Document 1. The excrement disposal material described in this document is composed of a plurality of granules having low water absorption, and is used in a system toilet. The system toilet includes a main body (tray) for receiving excreted urine, and a partition (screen) that divides the internal space of the main body into an upper space and a lower space. In the upper space (above the partition part), the plurality of granules described above are laid down. A water absorbent sheet that absorbs urine is arranged in the lower space. A through hole is formed in the partition part to allow urine to pass through but not to allow granular materials to pass through. Urine excreted into the main body passes through the gaps between the granules, and then moves from the upper space to the lower space through the through holes in the partition.

　このように粒状体の隙間を通り抜けた尿が貫通孔を通過するため、貫通孔の内面には、粒状体や尿の成分による汚れが付着しやすい。かかる汚れを放置しておくと、貫通孔が詰まったり、システムトイレの周囲に悪臭が漂ったりする原因となる。しかしながら、貫通孔は粒状体を通過させない程度に小さいため、貫通孔内には人の指が入らない。それゆえ、貫通孔の内面を人の指で擦って清掃することはできず、当該内面を清掃するには、貫通孔内に挿入可能な棒状のブラシ等の道具を用意しなければならないという問題があった。 Since the urine that has passed through the gaps between the granules passes through the through-holes, stains from the granules and urine components tend to adhere to the inner surface of the through-holes. If such dirt is left unattended, the through holes may become clogged and a foul odor may linger around the system toilet. However, the through-hole is small enough to not allow the granular material to pass through, so a human finger cannot enter the through-hole. Therefore, the inner surface of the through hole cannot be cleaned by rubbing it with a human finger, and in order to clean the inner surface, a tool such as a rod-shaped brush that can be inserted into the through hole must be prepared. was there.
　かかる問題を解消するために、貫通孔の径を１２．０ｍｍ以上とすることが考えられる。女性の小指の第１関節幅（第５指遠位関節幅）に関し、５０パーセンタイルは、１１．７ｍｍである。それゆえ、貫通孔の径が１２．０ｍｍ以上であれば、概ね半数以上の女性が小指を第１関節まで貫通孔に入れることができる。これにより、貫通孔の内面を小指の腹で擦って清掃することが可能になる。 In order to solve this problem, it is conceivable to set the diameter of the through hole to 12.0 mm or more. Regarding the first joint width (fifth finger distal joint width) of a female little finger, the 50th percentile is 11.7 mm. Therefore, if the diameter of the through hole is 12.0 mm or more, more than half of women can insert their little finger into the through hole up to the first joint. This makes it possible to clean the inner surface of the through hole by rubbing it with the pad of your little finger.
　ところが、このように貫通孔の径を１２．０ｍｍ以上とした場合、粒状体が貫通孔を通過して下部空間に落下してしまう。そのため、従来の排泄物処理材は、仕切部の貫通孔の径が１２．０ｍｍ以上であるシステムトイレにおいては使用することができない。 However, when the diameter of the through-hole is set to 12.0 mm or more in this way, the granules pass through the through-hole and fall into the lower space. Therefore, conventional excrement disposal materials cannot be used in system toilets in which the diameter of the through-hole in the partition is 12.0 mm or more.
　本発明は、上記課題に鑑みてなされたものであり、仕切部の貫通孔の径が１２．０ｍｍ以上であるシステムトイレにおいても使用することが可能な排泄物処理材、及びその製造方法を提供することを目的とする。 The present invention has been made in view of the above problems, and provides an excrement disposal material that can be used even in system toilets in which the diameter of the through hole in the partition is 12.0 mm or more, and a method for manufacturing the same. The purpose is to
　本発明による排泄物処理材は、排泄物を処理するための粒状体を備え、上記粒状体は、直径１２．０ｍｍの円形の開口を通過できない大きさを有することを特徴とする。 The excrement treatment material according to the present invention is characterized in that it includes granules for treating excrement, and the granules have a size that cannot pass through a circular opening with a diameter of 12.0 mm.
　この排泄物処理材においては、直径１２．０ｍｍの円形の開口を通過できない大きさを有する粒状体が設けられている。この場合、仕切部の貫通孔の径が１２．０ｍｍであるシステムトイレにおいて排泄物処理材を使用しても、粒状体が貫通孔を通過するのを防ぐことが可能となる。 This excrement disposal material is provided with granules having a size that cannot pass through a circular opening with a diameter of 12.0 mm. In this case, even if the excrement disposal material is used in a system toilet in which the diameter of the through-hole in the partition is 12.0 mm, it is possible to prevent particulate matter from passing through the through-hole.

　以下、図面を参照しつつ、本発明の実施形態について詳細に説明する。なお、図面の説明においては、同一要素には同一符号を付し、重複する説明を省略する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in the description of the drawings, the same elements are given the same reference numerals and redundant description will be omitted.
　図１は、本発明による排泄物処理材の一実施形態を示す模式図である。排泄物処理材１は、排泄物（主に尿）の処理に用いられる排泄物処理材である。排泄物処理材１は、猫や犬等の動物の排泄物の処理に用いられる動物用の排泄物処理材であってもよいし、人の排泄物の処理に用いられる人用の排泄物処理材であってもよい。排泄物処理材１は、排泄物を処理するための複数の粒状体１０を備えている。排泄物処理材１は、例えば、排泄された尿を受ける箱状の本体部と、本体部の内部空間を上部空間と下部空間とに区画する仕切部とを備えるシステムトイレにおいて使用される。その場合、排泄物処理材１は、複数の粒状体１０が仕切部上に直接敷設された状態で使用される。 FIG. 1 is a schematic diagram showing one embodiment of the excrement disposal material according to the present invention. The excrement treatment material 1 is an excrement treatment material used for treatment of excrement (mainly urine). The excrement disposal material 1 may be an animal excrement disposal material used to dispose of the excrement of animals such as cats and dogs, or a human excrement disposal material used to dispose of human excrement. It may be wood. The excrement treatment material 1 includes a plurality of granules 10 for treating excrement. The excrement disposal material 1 is used, for example, in a system toilet that includes a box-shaped main body for receiving excreted urine and a partition that divides the internal space of the main body into an upper space and a lower space. In that case, the excrement disposal material 1 is used with a plurality of granules 10 laid directly on the partition.
　各粒状体１０は、疎水性を有している。すなわち、粒状体１０は、尿等の液体を全く吸収しないか、あるいは吸収するとしても殆ど吸収しない性質を有する。粒状体１０が疎水性を有するというには、次の試験により測定される液通過率が６０％以上であることが必要である。まず、内径１０ｃｍ、目開き１ｍｍの篩に５０ｇ相当の粒状体１０（サンプル）を入れる。篩の下には、空のビーカーを設置する。そして、サンプルに対し、外筒の内径３ｃｍ、筒先の内径４ｍｍのシリンジ（テルモ社製６０ｍｌシリンジ）を用いて、３０ｍｌの水を１０秒かけて滴下する。１分間放置した後、ビーカー内の水量を計測する。計測した水量の滴下した水量（３０ｍｌ）に対する割合をもって液通過率とする。すなわち、ビーカー内の水量が１８ｍｌ以上であれば、液通過率が６０％以上となるため、粒状体１０が疎水性を有するといえる。 Each granule 10 has hydrophobicity. That is, the granular material 10 has the property of not absorbing liquid such as urine at all, or hardly absorbing it at all. In order for the granular material 10 to have hydrophobicity, it is necessary that the liquid passage rate measured by the following test be 60% or more. First, a granular material 10 (sample) equivalent to 50 g is placed in a sieve having an inner diameter of 10 cm and an opening of 1 mm. Place an empty beaker under the sieve. Then, 30 ml of water is dripped onto the sample over 10 seconds using a syringe (60 ml syringe manufactured by Terumo Corporation) with an outer cylinder having an inner diameter of 3 cm and a tip having an inner diameter of 4 mm. After leaving it for 1 minute, measure the amount of water in the beaker. The ratio of the measured amount of water to the amount of dropped water (30 ml) is defined as the liquid passage rate. That is, if the amount of water in the beaker is 18 ml or more, the liquid passage rate is 60% or more, so it can be said that the granular material 10 has hydrophobicity.
　図２は、粒状体１０を示す斜視図である。各粒状体１０は、粒状をしている。本実施形態において粒状体１０は、略柱状（具体的には略円柱状）をしている。ここで、略円柱状とは、粒状体１０が理想的には円柱状になるような方法で形成されている限り、完全な円柱形に限らず、円柱に近い形状も含む趣旨である。粒状体１０は、直径１２．０ｍｍの円形の開口を通過できない大きさを有している。ここで、「開口を通過できない」とは、粒状体１０は、向きをどのように変えても、変形しない限り、当該開口を通過できないということである。粒状体１０の底面の径ｄ１は、１２．０ｍｍよりも大きい。粒状体１０は、直径１３．０ｍｍ、直径１４．０ｍｍ、直径１５．０ｍｍ、直径１６．０ｍｍ、直径１７．０ｍｍ、直径１８．０ｍｍ、直径２０．０ｍｍ、又は直径２５．０ｍｍの円形の開口を通過できない大きさであることが好ましい。粒状体１０の底面の径ｄ１は、１３．０ｍｍ、１４．０ｍｍ、１５．０ｍｍ、１６．０ｍｍ、１７．０ｍｍ、１８．０ｍｍ、２０．０ｍｍ、又は２５．０ｍｍよりも大きいことが好ましい。 FIG. 2 is a perspective view showing the granular material 10. Each granular body 10 has a granular shape. In this embodiment, the granular material 10 has a substantially columnar shape (specifically, a substantially cylindrical shape). Here, the term "substantially cylindrical" is intended to include not only a perfect cylindrical shape but also a shape close to a cylindrical shape, as long as the granular material 10 is ideally formed in a cylindrical shape. The granular material 10 has a size that cannot pass through a circular opening with a diameter of 12.0 mm. Here, "cannot pass through the opening" means that the granular material 10 cannot pass through the opening unless it is deformed, no matter how the direction is changed. The diameter d1 of the bottom surface of the granular material 10 is larger than 12.0 mm. The granular body 10 has circular openings with a diameter of 13.0 mm, a diameter of 14.0 mm, a diameter of 15.0 mm, a diameter of 16.0 mm, a diameter of 17.0 mm, a diameter of 18.0 mm, a diameter of 20.0 mm, or a diameter of 25.0 mm. Preferably, the size is such that it cannot pass through. The diameter d1 of the bottom surface of the granular body 10 is preferably larger than 13.0 mm, 14.0 mm, 15.0 mm, 16.0 mm, 17.0 mm, 18.0 mm, 20.0 mm, or 25.0 mm.
　各粒状体１０は、有機物を主材料とすることが好ましい。ここで、粒状体１０の主材料とは、粒状体１０を構成する１又は２以上の材料のうち、当該粒状体１０に占める重量割合が最大のものをいう。かかる有機物としては、例えば、紙類、植物類、プラスチック類、又は有機汚泥類が挙げられる。各粒状体１０は、有機物のみからなっていてもよいし、有機物及び無機物からなっていてもよい。 It is preferable that each granular material 10 is mainly made of organic matter. Here, the main material of the granular material 10 refers to the material that accounts for the largest weight percentage in the granular material 10 among one or more materials that constitute the granular material 10 . Examples of such organic matter include papers, plants, plastics, and organic sludge. Each granular body 10 may be made of only organic matter, or may be made of both organic matter and inorganic matter.
　紙類は、パルプを主体とする材料をいう。紙類としては、例えば、通常の紙（紙粉）の他にも、塩ビ壁紙分級物、印画紙、剥離紙、又はフラッフパルプが挙げられる。塩ビ壁紙分級物は、紙及びポリ塩化ビニルを含有する塩ビ壁紙からポリ塩化ビニルの一部が除去されてなる。植物類としては、例えば、木粉、大鋸屑、又は植物性残渣（茶殻、オカラ等）が挙げられる。プラスチック類としては、例えば、通常のプラスチックの他にも、アルミ蒸着フィルム、又は紙おむつ分級物（紙おむつを分級することにより得られるプラスチック）が挙げられる。有機汚泥類としては、例えば、製紙スラッジ又はパルプスラッジが挙げられる。これらの材料には、疎水処理（撥水処理）が施されていてもよいし、施されていなくてもよい。 Paper refers to materials mainly made of pulp. Examples of the paper include, in addition to ordinary paper (paper powder), classified PVC wallpaper, photographic paper, release paper, and fluff pulp. A classified product of PVC wallpaper is obtained by removing a portion of polyvinyl chloride from paper and PVC wallpaper containing polyvinyl chloride. Examples of plants include wood flour, sawdust, and plant residues (tea leaves, okara, etc.). Examples of plastics include, in addition to ordinary plastics, aluminum vapor-deposited films and classified paper diapers (plastics obtained by classifying paper diapers). Examples of organic sludges include papermaking sludge and pulp sludge. These materials may or may not be subjected to hydrophobic treatment (water repellent treatment).
　粒状体１０を構成する材料は、１つのみであってもよいし、２つ以上であってもよい。前者の場合、粒状体１０を構成する材料は、上述の主材料のみということになる。後者の場合、粒状体１０は、主材料と他の材料との混合物によって構成されることになる。他の材料としては、例えば、石膏又は重曹が挙げられる。石膏又は重曹を加えることにより、粒状体１０に疎水性を付与しやすくなる。石膏又は重曹の量は、例えば、粒状体１０の全体に対して５重量％以上５０重量％未満である。 The number of materials constituting the granular body 10 may be one, or two or more. In the former case, the material constituting the granules 10 is only the above-mentioned main material. In the latter case, the granules 10 will be composed of a mixture of the main material and other materials. Other materials include, for example, gypsum or baking soda. By adding gypsum or sodium bicarbonate, it becomes easier to impart hydrophobicity to the granules 10. The amount of gypsum or sodium bicarbonate is, for example, 5% by weight or more and less than 50% by weight based on the entire granular material 10.
　続いて、本発明による排泄物処理材の製造方法の一実施形態として、排泄物処理材１の製造方法の一例を説明する。この製造方法は、粒状体形成工程を含んでいる。 Next, as an embodiment of the method for producing an excrement disposal material according to the present invention, an example of a method for producing the excrement disposal material 1 will be described. This manufacturing method includes a granule forming step.
　粒状体形成工程は、粒状体１０を形成する工程である。粒状体形成工程においては、造粒装置を用いて造粒材料（粒状体１０を構成する材料）を造粒することにより、粒状体１０となる複数の造粒物を形成する。造粒装置としては、例えば押出造粒機を用いることができる。造粒物には、必要に応じて疎水処理を施してもよい。疎水処理は、例えば、造粒物の表面を疎水剤（撥水剤）でコーティングすることにより行うことができる。疎水処理を行わない場合、造粒時に造粒材料に加わる圧力を高めることにより、造粒物内に空隙が極力生じないようにすることが好ましい。かかる空隙は、粒状体１０の内部に尿等の液体が浸入する経路となるからである。造粒に先立って、造粒材料には、粉砕、混錬、加水等の前処理が必要に応じて行われる。また、造粒後には、篩分け（分粒）、乾燥等の後処理が必要に応じて行われる。以上により、複数の粒状体１０からなる排泄物処理材１が得られる。 The granule forming step is a step of forming granules 10. In the granule forming step, a plurality of granules that will become the granules 10 are formed by granulating a granulation material (material constituting the granules 10) using a granulator. As the granulator, for example, an extrusion granulator can be used. The granules may be subjected to hydrophobic treatment if necessary. Hydrophobic treatment can be performed, for example, by coating the surface of the granules with a hydrophobic agent (water repellent). When hydrophobic treatment is not performed, it is preferable to increase the pressure applied to the granulated material during granulation to minimize the formation of voids in the granulated material. This is because such voids become a path for liquid such as urine to infiltrate into the inside of the granular material 10. Prior to granulation, the granulation material is subjected to pretreatments such as crushing, kneading, and adding water as necessary. Further, after granulation, post-treatments such as sieving (granulation) and drying are performed as necessary. Through the above steps, the excrement treatment material 1 consisting of a plurality of granules 10 is obtained.
　本実施形態の効果を説明する。本実施形態においては、直径１２．０ｍｍの円形の開口を通過できない大きさを有する粒状体１０が形成される。この場合、仕切部の貫通孔の径が１２．０ｍｍであるシステムトイレにおいて排泄物処理材１を使用しても、粒状体１０が貫通孔を通過するのを防ぐことが可能となる。すなわち、少なくとも、貫通孔の平面形状が直径１２．０ｍｍの円形であるシステムトイレにおいて、粒状体１０が貫通孔を通過するのを防ぐことができる。したがって、仕切部の貫通孔の径が１２．０ｍｍ以上であるシステムトイレにおいても使用することが可能な排泄物処理材１、及びその製造方法が実現されている。 The effects of this embodiment will be explained. In this embodiment, the granules 10 are formed so that they cannot pass through a circular opening with a diameter of 12.0 mm. In this case, even if the excrement disposal material 1 is used in a system toilet in which the diameter of the through-hole in the partition is 12.0 mm, it is possible to prevent the granular material 10 from passing through the through-hole. That is, at least in a system toilet in which the planar shape of the through hole is circular with a diameter of 12.0 mm, it is possible to prevent the granular material 10 from passing through the through hole. Therefore, the excrement disposal material 1 and its manufacturing method are realized which can be used even in a system toilet in which the diameter of the through-hole of the partition is 12.0 mm or more.
　粒状体１０は、略柱状をしている。柱状は、押出造粒によって成形しやすい形状である。それゆえ、略柱状の粒状体１０は、押出造粒機を用いて量産するのに適している。 The granular material 10 has a substantially columnar shape. The columnar shape is a shape that can be easily molded by extrusion granulation. Therefore, the substantially columnar granules 10 are suitable for mass production using an extrusion granulator.
　特に粒状体１０は、略円柱状をしている。略円柱状の粒状体１０は、平面視で円形のダイス孔を有する押出造粒機を用いて形成することができる。このようにダイス孔の平面形状が円形である場合、造粒時、造粒材料に対して均一に圧力を加えやすい。このことは、造粒をスムーズに実行するのに有利である。 In particular, the granular material 10 has a substantially cylindrical shape. The substantially cylindrical granules 10 can be formed using an extrusion granulator having circular die holes in plan view. When the planar shape of the die hole is circular in this way, it is easy to uniformly apply pressure to the granulated material during granulation. This is advantageous for smoothly performing granulation.
　粒状体１０の底面の径ｄ１は、１２．０ｍｍよりも大きい。この場合、粒状体１０は、その高さ（円柱の高さ）にかかわらず、直径１２．０ｍｍの円形の開口を通過できない。このため、直径１２．０ｍｍの円形の開口を通過できない大きさを有する粒状体１０を確実に実現することができる。 The diameter d1 of the bottom surface of the granular material 10 is larger than 12.0 mm. In this case, the granular material 10 cannot pass through the circular opening with a diameter of 12.0 mm regardless of its height (height of the cylinder). Therefore, it is possible to reliably realize the granular material 10 having a size that cannot pass through a circular opening having a diameter of 12.0 mm.
　粒状体１０は、疎水性を有している。この場合、粒状体１０上に排泄された尿の大部分は、粒状体１０に吸収されずに、粒状体１０どうしの隙間を通り抜けていく。これにより、尿を下方に速やかに導くことができる。 The granular material 10 has hydrophobicity. In this case, most of the urine excreted onto the granules 10 passes through the gaps between the granules 10 without being absorbed by the granules 10. Thereby, urine can be guided downward quickly.
　粒状体１０が直径１３．０ｍｍの円形の開口を通過できない大きさを有する場合、仕切部の貫通孔の径が１３．０ｍｍであるシステムトイレにおいて排泄物処理材１を使用しても、粒状体１０が貫通孔を通過するのを防ぐことが可能となる。 If the granular material 10 has a size that cannot pass through a circular opening with a diameter of 13.0 mm, even if the excrement disposal material 1 is used in a system toilet in which the diameter of the through hole in the partition is 13.0 mm, the granular material 10 will not pass through the circular opening with a diameter of 13.0 mm. 10 from passing through the through hole.
　女性の小指の第１関節幅に関し、９５パーセンタイルは、１２．７ｍｍである。それゆえ、貫通孔の径が１３．０ｍｍ以上であれば、殆どの女性が小指を第１関節まで貫通孔に入れることができる。 Regarding the width of the first joint of a female little finger, the 95th percentile is 12.7 mm. Therefore, if the diameter of the through hole is 13.0 mm or more, most women can insert their little finger into the through hole up to the first joint.

Therefore, if the diameter of the through hole is 14.0 mm or more, approximately half or more of women can insert their index finger into the through hole up to the first joint. This also makes it possible to clean the inner surface of the through hole by rubbing it with the pad of your index finger.
