Abstract
Description
本発明は、人又は動物（より好ましくは動物）の***物などの液体を吸収するための粒状の吸水処理材（以下単に「吸水処理材」という）及びその製造方法に関する。 The present invention relates to a granular water-absorbing treatment material (hereinafter simply referred to as “water-absorbing treatment material”) for absorbing liquid such as human or animal (more preferably, animal) excrement and a method for producing the same.
これまで、出願人は、人用又は家畜及び愛玩動物等の動物用の粒状***物処理材（以下「***物処理材」という。）を数多く出願している（例えば、特許文献１）。このような***物処理材は、吸水性能及び美観等を総合的に考慮して、直径４ｍｍ程度、長さ１０ｍｍ乃至１３ｍｍ程度の細長状（略円柱状）に成型された粒状の吸水体（以下、この程度の大きさから著しく逸脱せず、商品として適合するとされていた粒状の吸水体を「適合品」という。）が多数集合して構成されている。 So far, the applicant has filed many applications for particulate excrement disposal materials for humans or animals such as domestic animals and pets (hereinafter referred to as “excrement disposal materials”) (for example, Patent Document 1). Such a waste treatment material is a granular water-absorbing body (hereinafter referred to as a substantially cylindrical shape) having a diameter of about 4 mm and a length of about 10 mm to 13 mm in consideration of water absorption performance and aesthetics. A large number of granular water-absorbing bodies that are said to be suitable as products without deviating significantly from this size are called “compatible products”).
ところで、***物処理材の製造過程においては、小粒径の***物処理材や、大粒径の***物処理材など適合品と認められない（以下「規格外品」という。）各種の粒径の***物処理材が一定程度発生してしまっていた。 By the way, in the manufacturing process of the excrement disposal material, various types of particles (hereinafter referred to as “non-standard product”) that are not recognized as conforming products such as a small particle excrement disposal material and a large particle excrement disposal material. A certain amount of excrement disposal material of diameter has been generated.
このような規格外品のうち小粒径の***物処理材を使用すると、***物処理材が飛び散ったり、ペットの足（特に肉球など）や毛に付着してしまい、容器の外部にまき散らされ、その周囲を汚す等の問題点が生じていた。 If a non-standard waste treatment material with a small particle size is used, the waste treatment material may scatter or adhere to the pet's feet (especially meat balls) and hair, and be spread outside the container. There were problems such as being scattered and soiling the surroundings.
この点に関連して、***物処理材に炭酸カルシウム等の無機充填剤を加えて、その質量を重くする方法が開示されている（特許文献２）。 In relation to this point, a method is disclosed in which an inorganic filler such as calcium carbonate is added to the excrement disposal material to increase its mass (Patent Document 2).
また、大粒径の***物処理材に関しては、見栄えが悪い等の理由により規格外品とせざるをえないため、再度、***物処理材の原料とするなどの対応がなされていた。 In addition, the excrement disposal material having a large particle size has to be a non-standard product due to its poor appearance, and therefore, measures such as using it as a raw material for the excrement disposal material have been made again.
しかし、***物処理材に炭酸カルシウム等の無機充填剤を加える方法で質量を重くする方法では、小粒径の***物処理材には効果が乏しかった。また、ある程度重量を重くした場合であっても、ペットの足や毛に付着することを防止することは難しかった。 However, the method of increasing the mass by adding an inorganic filler such as calcium carbonate to the excrement disposal material is not effective for the excrement disposal material having a small particle size. Further, even when the weight is increased to some extent, it is difficult to prevent the pet from sticking to the feet and hair.
また、これまでの***物処理材に排尿した場合、粒径の寸法によっては***物が深さ方向に吸収されにくいため幅方向に広がり、遊離水が生じてしまう場合があり、このようなタイプの***物処理材は、強い汚臭が発生してしまうという問題点を有していた。 In addition, when urinating to the excrement treatment material so far, depending on the size of the particle size, the excrement is difficult to be absorbed in the depth direction, so it may spread in the width direction and free water may be generated. The excrement disposal material had a problem that a strong odor was generated.
これに加えて、愛玩動物は、一度排尿した***物処理材の部分を避けて***する習性があるため、このようなタイプの***物処理材を用いる場合には、頻繁に***物処理材を取り換える必要があることから、何らかの改善が望まれていた。 In addition to this, pet animals have the habit of evacuating the excrement disposal material that has been urinated once. Therefore, when using such a type of excrement disposal material, the excrement disposal material is frequently used. Some improvement was desired because it needs to be replaced.
さらに、***物処理材は粉砕された原材料を押出成型機を用いて押出成型することにより製造されるが、成型後に生じた大粒径の***物処理材を再利用した場合、当該押出成型機に目詰まりが生じやすくなるという問題点があった。 Furthermore, the excrement disposal material is manufactured by extruding the pulverized raw material using an extrusion molding machine. When the excrement disposal material having a large particle size generated after molding is reused, the extrusion molding machine is used. There is a problem that clogging is likely to occur.
本発明は、上記の問題点を解決するためになされたものであり、使用者又は使用動物等に付着せず、使用場所を汚すことを防ぐことが可能であり、吸水速度が速く、汚臭の発生を抑えることが可能であり、さらに、無駄になっていた吸水処理材を有効活用することが可能となる吸水処理材およ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 order to solve the above-mentioned problems, and does not adhere to the user or the animal to be used, can prevent the use place from being soiled, has a high water absorption speed, and has a foul odor. It is an object of the present invention to provide a water-absorbing treatment material and a method for producing the same, which are capable of suppressing the occurrence of the water-absorbing material and that can effectively utilize the water-absorbing treatment material that has been wasted.
上記課題を解決するために、本発明の吸水処理材は、複数の粒状吸水体が集合してなる吸水処理材であって、前記複数の粒状吸水体は、２５ｍｍの篩目を有する篩を通過し、かつ、５ｍｍ乃至８ｍｍ（より好ましくは５ｍｍ乃至６ｍｍ）の篩目を有する篩上に残留する大粒径の粒状吸水体と、３ｍｍ乃至４ｍｍの篩目を有する篩を通過する小粒径の粒状吸水体とから構成されており、その構成比は、大粒径の粒状吸水体が６５重量％乃至９０重量％、小粒径の粒状吸水体が３５重量％乃至１０重量％であることを特徴としている。 In order to solve the above-mentioned problem, the water-absorbing treatment material of the present invention is a water-absorbing treatment material in which a plurality of granular water-absorbing bodies are aggregated, and the plurality of granular water-absorbing bodies pass through a sieve having a 25 mm sieve mesh. In addition, a granular water-absorbing body having a large particle size remaining on a sieve having a sieve having a size of 5 mm to 8 mm (more preferably 5 mm to 6 mm) and a small particle having a diameter of 3 mm to 4 mm. The granular water absorbent is composed of 65% by weight to 90% by weight of the granular water absorbent having a large particle size, and 35% by weight to 10% by weight of the granular water absorbent having a small particle size. It is a feature.
また、前記吸水処理材において、前記複数の粒状吸水体は、粒状芯部と前記粒状芯部を被覆する被覆層部とを有する複層構造として構成することもできる。 Moreover, in the water-absorbing treatment material, the plurality of granular water-absorbing bodies can be configured as a multilayer structure having a granular core portion and a coating layer portion that covers the granular core portion.
ここで、前記粒状吸水体は、吸水性能又は保水性能を有していればその材質等に制限はなく、砂、ベントナイト、ゼオライト等の無機質材料や、製紙用パルプ、ケナフ、コーヒー抽出残渣、茶殻、パルプスラッジ等の有機質廃材を素材とし、これらの素材に吸水性樹脂を配合したものを構成材料とすることができる。
なお、吸水性樹脂とは、ポリマー、ＣＭＣ（カルボキシルメチルセルロース）、ポリビニルアルコール（ＰＶＡ）、澱粉（Ｔ−α化澱粉、デキストリン、小麦澱粉、馬鈴薯澱粉）などの吸水性能を備える樹脂であり、特に、ポリマーは高い吸水性能を有している高吸水性樹脂である。
Here, the granular water absorbent is not limited in its material and the like as long as it has water absorption performance or water retention performance, such as inorganic materials such as sand, bentonite and zeolite, pulp for papermaking, kenaf, coffee extraction residue, tea shells. Further, organic waste materials such as pulp sludge can be used as raw materials, and those obtained by blending a water absorbent resin with these raw materials can be used as constituent materials.
The water-absorbing resin is a resin having water-absorbing performance such as a polymer, CMC (carboxyl methyl cellulose), polyvinyl alcohol (PVA), starch (T-α starch, dextrin, wheat starch, potato starch), The polymer is a highly water-absorbing resin having high water absorption performance.
また、前記粒状吸水体の形状は、完全な球形等である必要はなく、所定寸法の篩目を通過する小塊の形状であれば、柱状体（細長形）、扁平形等、その形状は問わない。 In addition, the shape of the granular water absorber need not be a perfect sphere or the like, and if it is a small lump shape that passes through a sieve with a predetermined size, the shape of the columnar body (elongated), flat shape, etc. It doesn't matter.
また、前記篩目とは、本件においては篩の目開きのことで、例えばＪＩＳＺ８８０１−２に規定されているように、篩が角孔（正方目）を有するならば、その一辺の長さをミリメートルで表した数値であり、篩が円孔（円形目）を有するならば、その直径をミリメートルで表した数値である。 In addition, the sieve mesh in this case refers to the mesh opening of the sieve. For example, as defined in JISZ8801-2, if the sieve has a square hole (square mesh), the length of one side is defined as follows. It is a numerical value expressed in millimeters, and if the sieve has a circular hole (circular mesh), the diameter is a numerical value expressed in millimeters.
さらに、本発明の吸水処理材の製造方法は、複数の粒状吸水体が集合してなる吸水処理材の製造方法であって、前記粒状吸水体を製造する粒状吸水体製造工程と、前記粒状吸水体製造工程で製造された粒状吸水体を、２５ｍｍの篩目を有する篩を通過し、かつ、５ｍｍ乃至８ｍｍの篩目を有する篩上に残留する大粒径の粒状吸水体と、５ｍｍ乃至８ｍｍの篩目を有する篩を通過し、かつ、３ｍｍ乃至４ｍｍの篩目を有する篩上に残留する中粒径の粒状吸水体と、３ｍｍ乃至４ｍｍの篩目を有する篩を通過する小粒径の粒状吸水体とに篩い分ける分粒工程と、前記分粒工程で得られた大粒径の粒状吸水体と小粒径の粒状吸水体を、大粒径の粒状吸水体が６５重量％乃至９０重量％、小粒径の粒状吸水体が３５重量％乃至１０重量％となるように混合して前記吸収処理材とする混合工程とを含むことを特徴としている。 Furthermore, the method for producing a water-absorbing treatment material of the present invention is a method for producing a water-absorbing treatment material in which a plurality of granular water-absorbing bodies are aggregated, and includes a granular water-absorbing-material production step for producing the granular water-absorbing body, and the granular water-absorbing material. The granular water absorbent manufactured in the body manufacturing process passes through a sieve having a 25 mm sieve and remains on the sieve having a 5 mm to 8 mm sieve, and a 5 mm to 8 mm granular water absorbent Small particle size passing through a sieve having a mesh size of 3 mm to 4 mm and passing through a sieve having a mesh size of 3 mm to 4 mm. A sieving step for sieving into a granular water absorbent, a granular water absorbent having a large particle size and a granular water absorbent having a small particle size obtained in the sizing step, the granular water absorbent having a large particle size is 65% by weight to 90% So that the granular water-absorbing body having a small particle size of 35% by weight to 35% by weight to 10% by weight. It is characterized in that it comprises a mixing step of said absorption treatment member engages.
また、前記吸水処理材の製造方法において、前記分粒工程の後で前記混合工程の前に、前記大粒径の粒状吸水体と前記小粒径の粒状吸水体を乾燥させる乾燥工程を含む構成とすることや、前記粒状吸水体製造工程の後で前記分粒工程の前に、前記粒状吸水体を乾燥させる乾燥工程を含む構成とすることもできる。 The method for producing a water-absorbing treatment material includes a drying step of drying the large-particle-sized granular water absorbent and the small-particle-sized granular water absorbent after the sizing step and before the mixing step. It can also be set as the structure including the drying process which dries the said granular water absorbing body after the said granular water absorbing body manufacturing process and before the said sizing process.
さらに、前記粒状吸水体製造工程は、吸水性を有する基材により粒状の芯部を形成する造粒工程と、前記芯部の周囲に被覆層部を形成して前記粒状吸水体とする被覆工程とを含む構成とすることもできる。 Furthermore, the granular water absorbent manufacturing process includes a granulating process in which a granular core is formed from a water-absorbing substrate, and a coating process in which a coating layer is formed around the core to form the granular water absorbent. It can also be set as the structure containing these.
本発明の吸水処理材によれば、小粒径の粒状吸水体と、大粒径の粒状吸水体とを含んでいるため、容器等に入れた場合において、小粒径の粒状吸水体が大粒径の粒状吸水体間の間隙に入り込むことになる。そのため、主として大粒径の粒状吸水体が表層に露出し、小粒径の粒状吸水体が表層に露出することがないため、小粒径の粒状吸水体が使用者又は使用動物等に付着せず、当該小粒径の粒状吸水体が飛び散ることにより容器の外部にまき散らされてその周囲を汚すことを防止することができる。 According to the water-absorbing treatment material of the present invention, since the granular water-absorbing body having a small particle diameter and the granular water-absorbing body having a large particle diameter are included, the granular water-absorbing body having a small particle diameter is large when placed in a container or the like. It will enter into the gap between the granular water-absorbing bodies having a particle size. For this reason, the granular water-absorbing body having a large particle diameter is mainly exposed on the surface layer, and the granular water-absorbing body having a small particle diameter is not exposed on the surface layer. First, it is possible to prevent the small-particle-size granular water-absorbing body from being scattered and scattered around the outside of the container and soiling the surroundings.
また、大粒径の粒状吸水体は、小粒径の粒状吸水体と比較して間隙が多いため、吸水速度が速く、深さ方向に***物を透過させる性質に優れているため、***物が幅方向に広がってしまうことを防止し、汚臭の原因となる遊離水の発生を効果的に防止することができる。
この場合であっても、本発明の吸水処理材は、大粒径と小粒径の粒状吸水体を組み合わせて吸水処理材を形成しているため、接着性能にやや劣るという大粒径の粒状吸水体の欠点を小粒径の粒状吸水体が補うことができる。
In addition, the large particle-size water-absorbing body has more gaps than the small-particle-size water-absorbing body, so the water absorption speed is fast and excreted excrement in the depth direction. Can be prevented from spreading in the width direction, and the generation of free water causing odor can be effectively prevented.
Even in this case, the water-absorbing treatment material of the present invention forms a water-absorbing treatment material by combining a large particle size and a granular water-absorbing material having a small particle size, and thus has a large particle size that is slightly inferior in adhesive performance. A granular water absorbent having a small particle diameter can compensate for the drawbacks of the water absorbent.
さらに、これまで廃棄等していた小粒径の粒状吸水体と大粒径の粒状吸水体を有効活用することができるため、吸水処理材の製造コストの削減を図ることができる。
また、本発明の吸水処理材の各製造方法によれば、本発明の吸水処理材を効率的に製造することができる。
Furthermore, since it is possible to effectively use the granular water absorbent having a small particle diameter and the granular water absorbent having a large particle diameter, which have been discarded, the manufacturing cost of the water absorbent treatment material can be reduced.
Moreover, according to each manufacturing method of the water absorption processing material of this invention, the water absorption processing material of this invention can be manufactured efficiently.
本発明を実施するための一形態（以下「実施形態」という）について、猫等の愛玩動物用の***物処理材及びその製造方法を例として、図面を参照して詳細に説明する。 An embodiment for carrying out the present invention (hereinafter referred to as “embodiment”) will be described in detail with reference to the drawings, taking as an example an excrement disposal material for pets such as cats and a method for producing the same.

（３）混合割合
本発明の***物処理材は、上記芯部と上記被覆層部から形成され、構成材料は同じであるが粒径の異なる複数個の粒状吸水体を以下の配合割合で混合したとことに特徴を有している。すなわち、２５ｍｍ篩を通過し、かつ、５ｍｍ篩乃至８ｍｍ篩上に残留する粒径である大粒状の粒状吸水体を６５重量％ないし９０重量％、３ｍｍ篩乃至４ｍｍ篩を通過する粒径である小粒状の粒状吸水体を３５重量％ないし１０重量％となるように混合している。
(3) Mixing ratio The excrement disposal material of the present invention is formed from the core part and the coating layer part, and a plurality of granular water absorbent bodies having the same constituent material but different particle diameters are mixed at the following blending ratio. It has a special feature. That is, it is a particle size that passes through a 25 mm sieve and passes through a large granular water-absorbing body having a particle size remaining on the 5 mm sieve to 8 mm sieve by 65 wt% to 90 wt%, and 3 mm sieve to 4 mm sieve. A small granular water-absorbing body is mixed so as to be 35% by weight to 10% by weight.
（４）作用効果
発明の***物処理材によれば、小粒状の粒状吸水体と、大粒状の粒状吸水体とを含んでいるため、容器等に入れた場合において、小粒径の粒状吸水体が大粒径の粒状吸水体の間の間隙に入り込むことになる。そのため、主として大粒径の粒状吸水体が表層に露出し、小粒径の粒状吸水体が表層に露出することがないため、犬や猫等の愛玩動物に使用した場合に、肉球や毛などに付着することがなく、小粒径の粒状吸水体が飛び散ることにより容器の外部にまき散らされてその周囲を汚すことを防止することができる。
(4) Effects According to the excrement disposal material of the invention, since it includes a small granular water absorbent and a large granular water absorbent, the granular water absorbent having a small particle diameter when placed in a container or the like. The body enters the gap between the granular water-absorbing bodies having a large particle size. For this reason, the granular water-absorbing body having a large particle diameter is mainly exposed on the surface layer, and the granular water-absorbing body having a small particle diameter is not exposed on the surface layer. Therefore, when used for a pet such as a dog or cat, It is possible to prevent the granular water absorbing body having a small particle size from being scattered and scattered around the outside of the container and soiling the surroundings.
また、大粒径の粒状吸水体は、小粒径の粒状吸水体と比較して間隙が多いため、吸水速度が速く、深さ方向に***物を透過させる性質に優れている。そのため、***物が幅方向に広がり、遊離水が発生することを防ぐことができることから、汚臭の発生を効果的に防止することができる。 Moreover, since the large-particle-size granular water absorbing body has many gaps compared to the small-particle-size granular water absorbing body, the water absorbing speed is high and excels in the excretion in the depth direction. Therefore, since excrement spreads in the width direction and free water can be prevented from being generated, generation of foul odor can be effectively prevented.
この場合であっても、本発明の***物処理材は、大粒径と小粒径の粒状吸水体が組み合わされて形成されているため、接着性能がやや劣るという大粒径の粒状吸水体の欠点を小粒径の粒状吸水体が補うことができる。 Even in this case, the excrement disposal material of the present invention is formed by combining a large particle size and a small particle size water absorber, so that the large particle size water absorber whose adhesion performance is slightly inferior The above-mentioned disadvantage can be compensated for by a granular water absorbent having a small particle diameter.
［製造方法］
続いて、本発明の***物処理材の製造方法について、図１を参照して説明する。
[Production method]
Then, the manufacturing method of the excrement disposal material of this invention is demonstrated with reference to FIG.
本発明に係る***物処理材の製造方法は、造粒工程（Ｓ１〜Ｓ７）と、予備篩分工程（Ｓ８）と、被覆工程（Ｓ９，Ｓ１０）と、分粒工程（Ｓ１１，Ｓ１３，Ｓ１５）と、乾燥工程（Ｓ１２）と、混合工程（Ｓ１６）と、袋詰工程（Ｓ１７）とから構成されている。以下、各工程について説明する。 The method for producing excrement disposal materials according to the present invention includes a granulation step (S1 to S7), a preliminary sieving step (S8), a covering step (S9, S10), and a sizing step (S11, S13, S15). ), A drying step (S12), a mixing step (S16), and a bagging step (S17). Hereinafter, each step will be described.
（１）造粒工程
本工程は、芯部を形成する工程であり、粉砕工程、粉砕物混合工程、加水工程及び押出造粒工程から構成されている（Ｓ１〜Ｓ７）。
(1) Granulation step This step is a step of forming a core, and is composed of a pulverization step, a pulverized product mixing step, a hydration step, and an extrusion granulation step (S1 to S7).
１）粉砕工程
本工程は、芯部を形成する主材料を粉砕（破砕）するための工程である。
本工程では、有機質廃材等の主材料を粗破砕機で所定の大きさ（例えば４０ｍｍ）以下に粗破砕（第一次粉砕）し、その後、粉砕機でさらに所定の大きさ（例えば２〜４ｍｍ）以下に粉砕（第二次粉砕）する。
1) Crushing step This step is a step for crushing (crushing) the main material forming the core.
In this step, main materials such as organic waste materials are roughly crushed (primary pulverization) to a predetermined size (for example, 40 mm) or less with a rough crusher, and then further with a predetermined size (for example, 2 to 4 mm) with a pulverizer. ) The following pulverization (secondary pulverization).
図１では、主材料として塩化ビニル壁紙廃材及び紙おむつ廃材を用いた例を示す。塩化ビニル壁紙廃材は、粗破砕機で第一次粉砕した後に粉砕機で第二次粉砕し（Ｓ１，Ｓ２）、紙おむつ廃材は、粗破砕機で第一次粉砕した後に粉砕機で第二次粉砕するとともに（Ｓ３，Ｓ４）、分級機で吸水性ポリマー、紙粉（フラッフパルプ）を分離し、吸水性ポリマー及び紙粉を除いた外装体を主材料として使用する。 In FIG. 1, the example using the vinyl chloride wallpaper waste material and the disposable diaper waste material as a main material is shown. Waste vinyl chloride wallpaper is first pulverized by a coarse crusher and then secondarily pulverized by a pulverizer (S1, S2). Waste paper diaper material is first pulverized by a coarse pulverizer and then secondarily by a pulverizer. While pulverizing (S3, S4), the water-absorbing polymer and paper powder (fluff pulp) are separated by a classifier, and the outer package from which the water-absorbing polymer and paper powder are removed is used as the main material.
２）粉砕物混合工程
本工程は、粉砕された主材料を所定割合で混ぜ合わせるとともに、必要に応じて他の種類の有機質廃材や無機質材料、吸水性樹脂、着色物質、脱臭材料、消臭材料、防黴材料、検査用指示薬等の各種物質を添加混合するための工程である。
例えば、本工程では、粉砕された塩化ビニル壁紙廃材及び紙おむつ廃材を混合型ホッパーに投入するとともに、必要に応じて吸水性樹脂や脱臭材料等を所定量加え、これらを混ぜ合わせることにより芯部の基材とする（Ｓ５）。
2) Pulverized product mixing step This step mixes the pulverized main material at a predetermined ratio and, if necessary, other types of organic waste materials and inorganic materials, water-absorbing resins, colored substances, deodorizing materials, and deodorizing materials. It is a process for adding and mixing various substances such as anti-mold materials and inspection indicators.
For example, in this process, pulverized vinyl chloride wallpaper waste paper and paper diaper waste material are put into a mixed hopper, and a predetermined amount of water-absorbing resin, deodorizing material, etc. is added as necessary, and these are mixed to mix the core. A substrate is used (S5).
３）加水工程
本工程は、押出造粒を容易にするために基材に加水し、その水分含有率を２０重量％程度に高める工程である（Ｓ６）。
なお、前工程で着色物質を添加する代わりに、本工程で着色水を加水することにより、基材を着色してもよい。
3) Water adding step This step is a step of adding water to the base material to facilitate extrusion granulation and increasing its water content to about 20% by weight (S6).
In addition, you may color a base material by adding colored water at this process instead of adding a coloring substance at a previous process.
４）押出造粒工程
本工程は、基材を押出造粒する（Ｓ７）ことにより、芯部を形成する工程である。
例えば、本工程では、所定孔径（例えば４ｍｍ又は３ｍｍ）のダイスを備える押出式造粒装置（押出成型機）を用い、基材に圧力をかけながらそれをダイスから押し出し、押し出された基材を適宜の長さずつ切断することにより、細長状（略円柱状）の芯部を造粒する。
4) Extrusion granulation step This step is a step of forming the core by extruding and granulating the substrate (S7).
For example, in this step, an extrusion granulator (extrusion molding machine) equipped with a die having a predetermined hole diameter (for example, 4 mm or 3 mm) is used to extrude the extruded substrate from the die while applying pressure to the substrate. An elongated (substantially cylindrical) core part is granulated by cutting each appropriate length.
（２）予備篩分工程
本工程は、２５ｍｍの篩目をも通過しないような粒径の大きい粒状吸水体の生成を未然に抑制するために、幅２４〜２５ｍｍ程度のスリットを通過しない芯部を選別して上記加水工程に戻す工程である（Ｓ８）。
ここで選別される芯部は、例えば個々には適当な大きさを有する芯部が複数凝集して一塊状となったものである。また、後記するように芯部に被覆層部を形成した場合には、被覆層部の厚さだけその粒径が増加することになる。そのため、２５ｍｍの篩目を通過しないような粒状吸水体の生成を回避するには、スリットの幅は被覆層部の厚さ分を考慮して２５ｍｍよりも小さくすることで足りる。被覆層部形成前のこの段階において規格外の大きさの造粒物を抽出すれば、これを芯部の製造ラインに戻して再度押出造粒しても押出成型機の目詰まり等の原因にならないという利点がある。
(2) Preliminary sieving step In this step, in order to suppress the formation of a granular water absorbent having a large particle diameter so as not to pass through a 25 mm sieve, a core that does not pass through a slit having a width of about 24 to 25 mm. Is a step of selecting and returning to the hydration step (S8).
The core part selected here is, for example, one in which a plurality of core parts each having an appropriate size are aggregated to form a lump. Moreover, when a coating layer part is formed in the core part as will be described later, the particle diameter increases by the thickness of the coating layer part. Therefore, in order to avoid generation of a granular water absorbent that does not pass through a 25 mm sieve, it is sufficient to make the width of the slit smaller than 25 mm in consideration of the thickness of the coating layer portion. If a granulated product with a non-standard size is extracted at this stage before the coating layer is formed, even if it is returned to the core production line and extrusion granulated again, it may cause clogging of the extruder. There is an advantage of not.
（３）被覆工程
本工程は、芯部の周囲に被覆層部を形成する工程であり、調合工程及び被覆層部形成工程から構成されている（Ｓ９，Ｓ１０）。
(3) Covering step This step is a step of forming a covering layer portion around the core portion, and includes a blending step and a covering layer portion forming step (S9, S10).
１）調合工程
本工程は、被覆層部の構成材料（被覆材料）を調合するための工程である。
被覆材料は、例えば、０．３ｍｍ程度の粒径に微粉砕された紙粉と吸水性ポリマー等を混ぜ合わせることにより調合されるが（Ｓ９）、その吸水性ポリマーとしては、紙おむつの粉砕時に分級したものを用いることが好適である。
1) Preparation process This process is a process for preparing the constituent material (coating material) of the coating layer portion.
The coating material is prepared by, for example, mixing paper powder finely pulverized to a particle size of about 0.3 mm with a water-absorbing polymer (S9), and the water-absorbing polymer is classified at the time of crushing the paper diaper. It is preferable to use the above.
２）被覆層部形成工程
本工程は、芯部の表面全体に被覆材料を付着させることにより、芯部の周囲に被覆層部を形成する工程である。
すなわち、本工程では、調合工程で所定の配合比に調製された紙粉及び吸水性ポリマー等を成分とする被覆材料を、コーティング装置を用いて芯部の周囲に付着させることにより、被覆層部を形成して粒状吸水体を得る（Ｓ１０）。
2) Coating layer part formation process This process is a process of forming a coating layer part around a core part by making a covering material adhere to the whole surface of a core part.
That is, in this step, the coating layer portion is formed by adhering a coating material containing paper powder and a water-absorbing polymer, etc., prepared in a predetermined mixing ratio in the preparation step around the core portion using a coating apparatus. To obtain a granular water absorbent (S10).
（４）分粒工程
本工程は、粒状吸水体を大粒径の粒状吸水体、中粒径の粒状吸水体、小粒径の粒状吸水体に分粒する工程であり、第一次篩分工程（Ｓ１１）、第二次篩分工程（Ｓ１３）及び第三次篩分工程（Ｓ１５）から構成される。
(4) Sizing Step This step is a step of sizing the granular water absorbent into a large particle size granular water absorber, a medium particle size granular water absorber, and a small particle size granular water absorber. It consists of a process (S11), a secondary sieving process (S13), and a tertiary sieving process (S15).
１）第一次篩分工程
本工程は、粒状吸水体を幅２５ｍｍのスリット又は直径２５ｍｍの円孔を通過させることにより、２５ｍｍの篩目を通過しないような特大の粒状吸水体を除去する工程であり（Ｓ１１）、本工程で、特大の粒状吸水体が除去された粒状吸水体は後記乾燥工程で乾燥され、第二次篩分工程に送られることになる。
なお、２５ｍｍの篩目を通過しないような粒状吸水体を除去し得れば、必ずしも篩を使用して行う必要はなく、上記のように予備篩分工程を設けていれば、本工程で分離されるものはほとんどない場合もあるので、本工程と予備篩分工程は選択的に設けてもよい。
1) Primary sieving step This step is a step of removing an oversized granular water absorbent that does not pass through a 25 mm sieve by passing the granular water absorbent through a slit having a width of 25 mm or a circular hole having a diameter of 25 mm. (S11), and in this step, the granular water absorbent from which the extra large granular water absorbent has been removed is dried in the post-drying step and sent to the secondary sieving step.
If a granular water absorbent that does not pass through a 25 mm sieve can be removed, it is not always necessary to use a sieve. If a preliminary sieving step is provided as described above, separation is performed in this step. Since there is a case where almost nothing is done, this step and the pre-sieving step may be selectively provided.
また、ここで除去されるような粒径の大きい粒状吸水体は、予備篩分工程において抽出分離される芯部と同様、複数の小さな粒状吸水体が結合して一体化することにより生じることもある。 In addition, the granular water absorbent having a large particle size as removed here may be produced by combining and integrating a plurality of small granular water absorbents in the same manner as the core portion extracted and separated in the preliminary sieving step. is there.
２）第二次篩分工程
本工程は、粒状吸水体を一次的に分粒し、適合品を選別する工程である（Ｓ１３）。
例えば、本工程では、乾燥工程で得られた粒状吸水体を振動型篩機により分粒する。本実施形態では、振動型篩機には、押出成型機のダイスの孔径が４ｍｍであれば上段に８〜１０ｍｍ、下段に４〜５ｍｍの篩目を有する篩が設けられ、ダイスの孔径が３ｍｍであれば上段に７〜８ｍｍ、下段に３〜４ｍｍの篩目を有する篩が設けられる。そして、乾燥工程において得られた粒状吸水体を、上段の篩上に散布した状態でその篩を振動させることにより、８〜１０ｍｍ又は７〜８ｍｍの粗い篩目を通過しない粒状吸水体を、それを通過する粒状吸水体と分離する。粗い篩目を通過した粒状吸水体は、下段の篩上に散布され、その篩を振動させることにより、４〜５ｍｍ又は３〜４ｍｍの細かい篩目を通過する粒状吸水体を、それを通過しない粒状吸水体と分離する。
2) Secondary sieving step This step is a step of primarily sizing the granular water-absorbing body and selecting compatible products (S13).
For example, in this step, the granular water absorbent obtained in the drying step is sized by a vibrating sieve. In this embodiment, if the hole diameter of the die of the extrusion molding machine is 4 mm, the vibration type sieve is provided with a sieve having a mesh size of 8 to 10 mm in the upper stage and 4 to 5 mm in the lower stage, and the hole diameter of the die is 3 mm. If so, a sieve having meshes of 7 to 8 mm in the upper stage and 3 to 4 mm in the lower stage is provided. And the granular water absorbing body obtained in the drying step is vibrated on the upper sieve, and the sieve is vibrated to thereby remove the granular water absorbing body that does not pass through the coarse mesh of 8 to 10 mm or 7 to 8 mm. It separates from the granular water absorption body which passes through. The granular water absorbent that has passed through the coarse sieve is spread on the lower sieve, and by vibrating the sieve, the granular absorbent that passes through the fine sieve of 4 to 5 mm or 3 to 4 mm does not pass through it. Separated from granular water absorbent.
上段の篩の篩目を通過し、かつ、下段の篩の篩目を通過しなかった粒状吸水体は、適合品として適合品袋詰工程に送られ、袋詰装置により所定量ずつ袋詰めされて、従来同様の粒の揃った***物処理材として出荷される（Ｓ１４）。
一方、それ以外の粒状吸水体は再度の選別のため第三次篩分工程に送られる。
The granular water absorbent that has passed through the screen of the upper screen and has not passed through the screen of the lower screen is sent to the compatible product bagging process as a compatible product, and is packed in a specified amount by the bagging device. Then, it is shipped as an excrement disposal material with the same grains as before (S14).
On the other hand, other granular water absorbents are sent to the third sieving step for re-selection.
３）第三次篩分工程（特許請求の範囲における分粒工程に相当）
本工程は、粒状吸水体を二次的に分粒し、適合品を再度選別する工程である（Ｓ１５）。
例えば、本工程では、第二次篩分工程で適合品として除去された以外の粒状吸水体を振動型篩機により分粒する。本実施形態では、振動型篩機には、上段から順に２５ｍｍの篩目を有する篩（以下「第一の篩」という。）、７〜８ｍｍ（ダイスの孔径が４ｍｍの場合）又は５〜６ｍｍ（ダイスの孔径が３ｍｍの場合）の篩目を有する篩（以下「第二の篩」という。）、３〜４ｍｍの篩目を有する篩（以下「第三の篩」という。）、１〜２ｍｍの篩目を有する篩（以下「第四の篩」という。）が積層的に設けられる。そして、第二次篩分工程で上段の篩上に残留した又は下段の篩を通過した粒状吸水体を第一の篩上に散布し、各篩を振動させることにより、第一の篩上に残留する粒状吸水体と、第一の篩を通過して第二の篩上に残留する粒状吸水体と、第二の篩を通過して第三の篩上に残留する粒状吸水体と、第三の篩を通過して第四の篩上に残留する粒状吸水体と、第四の篩を通過する粒状吸水体とに分離し、第二の篩を通過して第三の篩上に残留する中粒径の粒状吸水体は適合品として上記の適合品袋詰工程（Ｓ１４）に送り、第一の篩を通過して第二の篩上に残留する大粒径の粒状吸水体と第三の篩を通過して第四の篩上に残留する小粒径の粒状吸水体は第三次篩分工程に送る。
3) Third sieving step (corresponding to the sizing step in the claims)
This step is a step of secondarily sizing the granular water absorbent and reselecting the compatible product (S15).
For example, in this step, the granular water absorbent other than that removed as a conforming product in the second sieving step is sized by a vibrating sieve. In this embodiment, the vibration type sieve machine has a sieve having a mesh size of 25 mm in order from the top (hereinafter referred to as “first sieve”), 7 to 8 mm (when the die has a hole diameter of 4 mm), or 5 to 6 mm. (When the hole diameter of the die is 3 mm) a sieve having a sieve (hereinafter referred to as “second sieve”), a sieve having a 3-4 mm sieve (hereinafter referred to as “third sieve”), 1 to A sieve having a 2 mm mesh (hereinafter referred to as “fourth sieve”) is provided in a stacked manner. Then, the granular water-absorbing body remaining on the upper sieve in the second sieving step or passing through the lower sieve is sprayed on the first sieve, and each sieve is vibrated, thereby causing the first sieve to vibrate. A granular water absorbent remaining, a granular water absorbent passing through the first sieve and remaining on the second sieve, a granular water absorbent passing through the second sieve and remaining on the third sieve, The granular water absorbent that passes through the third sieve and remains on the fourth sieve is separated into the granular water absorbent that passes through the fourth sieve, and passes through the second sieve and remains on the third sieve. The medium-sized granular water absorbent is sent to the above-mentioned conforming product bagging step (S14) as a conforming product, and passes through the first sieve and remains on the second sieve, The small-diameter granular water absorbent passing through the third sieve and remaining on the fourth sieve is sent to the third sieving step.
なお、上記説明では、第二次篩分工程で上段の篩上に残留した又は下段の篩を通過した粒状吸水体を第一の篩上に散布しているが、残留又は通過した粒状吸水体の粒径の大きさによっては、第二の篩又は第三の篩上に散布することにしてもよい。
また、第四の篩を通過するような微細な粒状吸水体は、第四の篩を用いずにエアブロー等で小粒径の粒状吸水体から分離してもよく、前述した大粒径の粒状吸水体は、第一の篩によらずに予備篩分工程又は第一次篩分工程の篩分けによって２５ｍｍの篩目を通過するとしてもかまわない。
さらに、第二次篩分工程及び第三次篩分工程においても、第一次篩分工程におけると同様に、所定の大きさの篩目を通過したり通過しなかったりする粒状吸水体を選別し得れば、必ずしも篩を使用して篩分けする必要はない。
In the above description, the granular water absorbent remaining on the upper sieve in the secondary sieving step or passing through the lower sieve is sprayed on the first sieve. Depending on the size of the particle size, it may be sprayed on the second sieve or the third sieve.
The fine granular water absorbent that passes through the fourth sieve may be separated from the small granular water absorbent by air blow or the like without using the fourth sieve. The water absorbing body may pass through a 25 mm sieve by sieving in the preliminary sieving step or the primary sieving step, without using the first sieve.
Furthermore, in the secondary sieving step and the tertiary sieving step, as in the primary sieving step, a granular water absorbent that passes or does not pass through a sieve having a predetermined size is selected. If possible, it is not always necessary to screen using a sieve.
（５）乾燥工程
本工程は、第一次篩分工程において一次的に調粒（分粒）された粒状吸水体を、乾燥機で乾燥させる工程である（Ｓ１２）。
本工程では、既に第一次篩分工程において特大の粒状吸水体が除かれているので、製品とならない特大の粒状吸水体が乾燥対象に含まれることによる乾燥効率の低下を回避することができるという利点がある。
(5) Drying step This step is a step of drying the granular water absorbent that has been primarily sized (sized) in the first sieving step with a dryer (S12).
In this step, since the oversized granular water absorbent has already been removed in the primary sieving step, it is possible to avoid a decrease in drying efficiency due to the inclusion of oversized granular water absorbent that is not a product in the drying target. There is an advantage.
（６）混合工程
本工程は、第三次篩分工程で分離された大粒径の粒状吸水体と小粒径の粒状吸水体とを、大粒径の粒状吸水体と小粒径の粒状吸水体とが所定の構成比率となるように混合する工程である（Ｓ１６）。
本工程では、ホッパー等を使用し、大粒径の粒状吸水体が６５重量％乃至９０重量％の範囲内の所定の重量比率となり、小粒径の粒状吸水体が３５重量％乃至１０重量％の範囲内の所定の重量比率となるような割合で大粒径の粒状吸水体と小粒径の粒状吸水体とを混合し、本発明に係る***物処理材としている。
(6) Mixing step This step comprises mixing the large particle size granular water absorbent and the small particle size granular water absorbent separated in the third sieving step into the large particle size granular water absorbent and the small particle size granular particles. This is a step of mixing so that the water absorbing body has a predetermined composition ratio (S16).
In this step, a hopper or the like is used, and the granular water absorbent having a large particle diameter has a predetermined weight ratio in the range of 65 wt% to 90 wt%, and the granular water absorbent having a small particle diameter is 35 wt% to 10 wt%. The granular water-absorbing body having a large particle diameter and the granular water-absorbing body having a small particle diameter are mixed at a ratio such that the predetermined weight ratio is within the range of the above, and the excrement treatment material according to the present invention is obtained.
（７）袋詰工程
本工程は、混合工程で得た本発明の***物処理材を袋詰装置により所定量ずつ袋詰めし、大粒径の粒状吸水体及び小粒径の粒状吸水体からなる***物処理材として出荷する（Ｓ１７）。
(7) Bagging step This step is to pack the excrement disposal material of the present invention obtained in the mixing step by a predetermined amount with a bagging device, and from the granular water absorbent having a large particle size and the granular water absorbent having a small particle size. To be shipped as an excrement disposal material (S17).
［作用効果］
本発明の***物処理材の製造方法によれば、***物処理材を構成する大粒径又は小粒径の粒状吸水体として、適合品の製造ラインで生じる規格外品の粒状吸水体を用いることができる。これにより、規格外品の粒状吸水体を製造ラインに戻すことによる押出成型機の目詰まり等のリスクを負うことなく、規格外品の粒状吸水体を廃棄せずにその有効活用を図ることが可能となるため、延いては***物処理材を製造コストに優れたものとすることができる。
[Function and effect]
According to the method for producing a waste treatment material of the present invention, a non-standard granular water absorbent produced in a production line of a conforming product is used as a granular water absorbent having a large particle size or a small particle size constituting the waste treatment material. be able to. As a result, the non-standard granular water absorbent can be effectively utilized without discarding the non-standard granular water absorbent without risking clogging of the extrusion molding machine by returning the non-standard granular water absorbent to the production line. Since it becomes possible, the excrement disposal material can be made excellent in manufacturing cost.
また、本発明では、第二次篩分工程と第三次篩分工程を設けているため、正確に粒状吸水体を所定粒度に分粒することができる。特に、第二次篩分工程では、８〜１０ｍｍ（ダイスの孔径が４ｍｍの場合）又は７〜８ｍｍ（ダイスの孔径が３ｍｍの場合）の粗い篩目を通過しない粒状吸水体と、４〜５ｍｍ（ダイスの孔径が４ｍｍの場合）又は３〜４ｍｍ（ダイスの孔径が３ｍｍの場合）の細かい篩目を通過する粒状吸水体とを、それぞれ分離し、分離された粒状吸水体をさらに第三次篩分工程において、７〜８ｍｍ（ダイスの孔径が４ｍｍの場合）又は５〜６ｍｍ（ダイスの孔径が３ｍｍの場合）の粗い篩目を通過しない粒状吸水体と、３〜４ｍｍの細かい篩目を通過する粒状吸水体に分離している。このように、第二次篩分工程と第三次篩分工程において、粗い篩目と、細かい篩目の篩目の寸法を異なるように設定していることから、単に同じ篩目の寸法の篩を組み合わせた場合と比べて、より正確に粒状吸水体を所定粒度に分粒することができ、適合品及び本発明に係る***物処理材のいずれの見栄えも良好化することができる。 Moreover, in this invention, since the secondary sieving process and the tertiary sieving process are provided, the granular water absorbing body can be accurately sized to a predetermined particle size. In particular, in the secondary sieving step, a granular water absorbent that does not pass through a coarse sieve mesh of 8 to 10 mm (when the hole diameter of the die is 4 mm) or 7 to 8 mm (when the hole diameter of the die is 3 mm), and 4 to 5 mm. (When the hole diameter of the die is 4 mm) or 3-4 mm (when the hole diameter of the die is 3 mm) is separated from the granular water absorbent passing through the fine mesh, and the separated granular water absorbent is further tertiary. In the sieving step, a granular water absorbent that does not pass through 7-8 mm (when the hole diameter of the die is 4 mm) or 5-6 mm (when the hole diameter of the die is 3 mm) and a fine sieve having 3-4 mm It is separated into a granular water absorbent that passes through. In this way, in the secondary sieving step and the tertiary sieving step, since the sizes of the coarse sieve mesh and the fine sieve mesh are set differently, the dimensions of the same sieve mesh are simply set. Compared with the case where a sieve is combined, the granular water-absorbing body can be more accurately sized to a predetermined particle size, and the appearance of both the conforming product and the excrement disposal material according to the present invention can be improved.
［他の実施形態］
以上、本発明について、好適な実施形態についての一例を説明したが、本発明は当該実施形態に限られず、本発明の趣旨を逸脱しない範囲で適宜設計変更が可能である。
[Other Embodiments]
As mentioned above, although an example about a suitable embodiment was explained about the present invention, the present invention is not restricted to the embodiment concerned, and a design change is possible suitably in the range which does not deviate from the meaning of the present invention.
特に、上記実施形態では、粒状の芯部と当該芯部を被覆する被覆層部から構成される二層構造の***物処理材を例として説明を行ったが、本発明の***物処理材は、被覆層部を有しない粒状吸水体のみから構成されているものであってもよい。
この場合の粒状吸水体は、上記実施形態の***物処理材における芯部を形成する材料と同様の材料を用いることができ、適宜、上記と同様の着色物質、尿検査用指示薬、脱臭剤、接着作用を配合してもよい。
In particular, in the above embodiment, the two-layered excrement disposal material composed of a granular core and a coating layer covering the core has been described as an example. Further, it may be composed only of a granular water absorbent that does not have a coating layer portion.
In this case, the granular water-absorbing body can use the same material as the material that forms the core in the excrement disposal material of the above-described embodiment, and, as appropriate, the same colored substance, urinalysis indicator, deodorant, An adhesive action may be blended.
さらに、本発明の***物処理材の製造方法は、予備篩分工程及び第一次篩分工程を省略することや、第二次篩分工程を省略することも可能である。
また、第一次篩分工程と第二次篩分工程との間に設けられている乾燥工程を、第三次篩分工程と混合工程の間に設けることもできる。このように篩分工程が乾燥工程に先行する製造方法を採ることにより、乾燥工程における乾燥対象が第三次篩分工程で分離された大粒径の粒状吸水体又は小粒径の粒状吸水体だけとなり、乾燥工程で使用する乾燥機を小型化しやすくなるという利点がある。なお、上記実施形態におけるように乾燥工程が第二次篩分工程や第三次篩分工程に先行すると、粒状吸水体を一括して乾燥させることにより、大粒径の粒状吸水体の乾燥と小粒径の粒状吸水体の乾燥とを別々に管理する必要がないという利点がある。そのため、乾燥工程はそれらの利点を考慮した上で、適切な段階に設けることになる。
なお、大粒径の粒状吸水体及び小粒径の粒状吸水体は、それ自体を目的として製造してもかまわないが、これまで述べてきたように適合品の製造過程において生じた規格外品を利用する方が、コスト的に大幅に有利であることは言うまでもない。
Furthermore, the excrement disposal material manufacturing method of the present invention can omit the preliminary sieving step and the primary sieving step, or can omit the secondary sieving step.
Moreover, the drying process provided between the primary sieving process and the secondary sieving process can also be provided between the tertiary sieving process and the mixing process. As described above, the sieving step adopts a manufacturing method preceding the drying step, so that the granular water absorbent having a large particle size or the small particle size water absorbent separated in the third sieving step in the drying step. Therefore, there is an advantage that the dryer used in the drying process can be easily downsized. In addition, when the drying process precedes the secondary sieving process or the tertiary sieving process as in the above embodiment, the granular water absorbent is dried together, thereby drying the granular water absorbent having a large particle diameter. There is an advantage that it is not necessary to manage the drying of the granular water absorbent having a small particle size separately. Therefore, the drying process is provided at an appropriate stage in consideration of these advantages.
The granular water absorber with large particle size and the granular water absorber with small particle size may be manufactured for the purpose of itself, but as described above, non-standard products generated in the manufacturing process of conforming products. Needless to say, it is significantly more advantageous in terms of cost.
さらに、吸水処理材の用途についても吸水効果が得られるものであれば、その用途を問うものではない。例えば、愛玩動物の***物処理材に限られるものではなく、人間用の***物処理材、災害用トイレ処理材、災害用浸水処理材（浸水後の吸水処理に用いたり、浸水を防ぐ目的（内部に導水可能となるような袋体に吸水処理材を充填させ、土嚢類似の態様で使用する））、あるいは、排水（廃水）処理材としても利用することができる。 Further, the use of the water-absorbing treatment material is not limited as long as the water absorption effect can be obtained. For example, it is not limited to the excrement disposal material of pet animals, but is a human excrement disposal material, disaster toilet treatment material, disaster inundation treatment material (for the purpose of water absorption treatment after flooding, or to prevent inundation ( It can also be used as a wastewater (waste water) treatment material by filling the bag body with water-absorbing treatment material into the inside and using it in a manner similar to a sandbag).
本発明の***物処理材の性能を調べるために、大粒径の粒状吸水体と小粒径の粒状吸水体の配合比率を５重量％単位で変化させてサンプルを作成し、吸水幅を測定した。なお、サンプル番号０の適合品は、６ｍｍ篩を通過し、かつ、４ｍｍ篩に残留する粒状吸水体（適合品）から作成されており、適合品に準じる性能を有している。 In order to examine the performance of the excrement disposal material of the present invention, a sample was prepared by changing the mixing ratio of the granular water absorbent having a large particle diameter and the granular water absorbent having a small particle diameter in units of 5% by weight, and the water absorption width was measured. did. In addition, the conformity product of sample number 0 is made from the granular water absorbing body (conformity product) which passes a 6 mm sieve and remains on a 4 mm sieve, and has the performance according to a conformity product.
［サンプルの作成方法］

[Measurement method of water absorption width]
Keeping small pets such as dogs and cats in mind, each sample filled with 30 ml of simulated urine (ammonia-containing water), which is the standard amount of excretion, is allowed to absorb water, and the water absorption width at that time Was measured. This water absorption width (W) is obtained by injecting pseudo water into one point and measuring the maximum value of the diameter of the water absorption range from the water injection point. The smaller the value, the more excrement treatment materials in the narrow range. It is considered that the simulated urine was absorbed in the water, and the water absorption performance tends to be high.
