Description

  The present invention relates to a human or animal granular excrement disposal material and a method for producing the same, and in particular, for human or paperboard waste material powder to which hemihydrate gypsum obtained by treating gypsum board waste material adheres. It is related with the granular excrement disposal material for animals, and its manufacturing method.

Granular excrement disposal materials for humans and animals, especially indoor granular excrement disposal materials, such as sand, bentonite, zeolite and other inorganic materials, coffee liquor extraction residue, tea husk, pulp for papermaking, pulp sludge, etc. The organic waste material is mixed with a water-absorbing resin and molded into a small lump or granule.
On the other hand, gypsum board is made of gypsum as a main component, for example, a plate-shaped molded body made by mixing sawdust and other lightweight aggregates, and covered on both sides with paperboard. It has excellent properties of sound insulation, sound absorption, workability, and dimensional stability, and is used in large quantities as a building material. However, it is generated in large quantities as waste gypsum board when building is demolished or constructed. In the case of gypsum board waste such as waste gypsum board generated in a large amount in this way, the magnetic material such as iron was removed by magnetically selecting the crushed material by the crusher with a magnetic separator, and the magnetic material such as iron was removed. The crushed material of the gypsum board waste material is crushed by a secondary crusher, and the crushed material is passed through, for example, a trommel separator to collect the gypsum. However, when the waste gypsum board is pulverized, a part of the gypsum is separated from the paperboard, but the gypsum adhering to the paperboard is separated together with the paperboard while being fixed to the paperboard. The paperboard thus separated has gypsum fixed to 70% by weight or more, and therefore cannot be used as a paperboard and is incinerated. Moreover, even in the separated gypsum, since it is inevitable that paperboard to fix the gypsum is mixed, it is difficult to collect high-quality gypsum and is discarded.

Therefore, it has been proposed to granulate a paperboard crushed paper piece to which a thin layer of gypsum obtained by crushing waste gypsum board adheres to form a granular animal excrement disposal material. However, a considerable amount of gypsum is attached to the crushed material of the recycled paperboard part obtained by crushing gypsum board waste, and it adheres to the blade of the crusher at the crushing stage, and the crushing capacity is reduced. At the time of extrusion granulation, the clogging occurs due to adhering to the opening of the die, the particle shape of the granulated product becomes irregular, and the paperboard portion in the pulverized product of the recycled paperboard portion is only 30% by weight or less. For this reason, the granulated material is difficult to absorb water and wets and adheres to each other, and the coating layer covering the granulated particles is difficult to handle by peeling off at the time of drying.

The inventor then converted the paperboard on which the dihydric gypsum is fixed into a semi-hydrogypsum by a dehydration reaction under heat treatment in a rotary furnace or the like. It was discovered that the amount of gypsum attached to the paperboard part can be reduced to 10% by weight or less by detaching from the part. Furthermore, the present inventor can crush the gypsum board dihydrate gypsum into hemihydrate gypsum without adhering to the blade of the crusher at the crushing stage, improving crushing capability, and improving the opening of the die. Granules with uniform particle shape can be efficiently produced with less clogging, and the granule particles absorb water appropriately, and the granule particles do not adhere to each other. It has been discovered that peeling of the coating layer of the granular material can be reduced. The present invention is based on these findings.

In general, the gypsum board is generally composed of 10 to 30% by weight of paperboard and 90 to 70% by weight of dihydrate gypsum. However, according to the present invention, a small amount of semi-gypsum produced by the recycling treatment of waste gypsum board is used. The pulverized waste paperboard to which water gypsum adheres is 5 to 10% by weight of hemihydrate gypsum and 95 to 90% by weight of paperboard, and can be used as a raw material for excrement disposal materials. Therefore, according to the present invention, it is possible to collect a paperboard with a small amount of gypsum from waste gypsum board that has been incinerated without being used conventionally, and effectively use it as a raw material for granular excrement disposal materials. In addition, it is possible to provide a stable and inexpensive granular excrement disposal material having a moderate water absorption capacity.

  In the present invention, the granular excrement disposal material includes a pulverized paperboard material having a particle size of 5 millimeters or less and adhering hemihydrate gypsum to at least a part thereof, and a pulverized organic fiber material waste material that is smaller than the pulverized paperboard material. A material having a smaller amount of adhesiveness than the pulverized organic fiber material waste or a material having an adhesiveness smaller than that of the pulverized organic fiber material waste and a substance having a bactericidal action, It is formed into a granular material having a particle size of millimeter or more, or further, the granular material is used as a granular core portion, covering at least a part of the surface of the granular core portion, and having a paper powder having a particle size of 0.2 mm or less and adhesiveness.

In the present invention, the coating layer portion formed on the surface of the excrement disposal material absorbs excrement after being used for excretion, and the particles of the excrement disposal material adhere or bind to each other to form an aggregated mass. It is provided for forming.

In the present invention, the pulverized paperboard waste used as one of the raw materials is preferably produced from waste gypsum board discharged in large quantities as building waste. In the waste gypsum board, the gypsum component is fixed to the paperboard in the form of dihydrate gypsum, but the waste gypsum board is fixed to the paperboard part by heating to a temperature within the range of 60 to 150 ° C. When water gypsum is chemically changed to hemihydrate gypsum, the gypsum component that has become hemihydrate gypsum is detached from the paperboard and disintegrates, so the hemihydrate gypsum can be separated from the paperboard in the sieving process. Adhering gypsum components can be significantly reduced. For example, a waste gypsum board having a particle size of 50 mm or less is heated in a rotary kiln type pyrolysis furnace at a temperature within the range of 60 to 150 ° C., preferably within a range of 100 to 150 ° C., of the dehydration reaction temperature of dihydrate gypsum. By heat decomposition treatment at a temperature, the dihydrate gypsum of the waste gypsum board is converted into semi-water gypsum and the waste gypsum board is crushed. In the crushed waste gypsum board that has been crushed by the semi-water gypsum in this way, the gypsum component can be obtained as a paperboard waste material with less gypsum component by separating fine particles with a particle size of 0.1 mm or less. . In order to use this paperboard waste material as a raw material for granular excrement disposal materials, this pyrolyzed crushed material is further pulverized, for example, to a particle size of 5 mm or less, and fine particles having a particle size of 0.1 mm or less are separated from the pulverized material. By doing so, it is possible to obtain waste paperboard with less gypsum.
In the present invention, the waste gypsum board can be crushed, for example, after heating to a temperature in the range of 60 to 150 ° C. to convert the dihydrate gypsum to hemihydrate gypsum. It can also be performed while heating the waste gypsum board to a temperature in the range of 150 ° C.

In the present invention, the waste gypsum board is heated to a temperature of 60 ° C. or higher, preferably in the range of 100 ° C. to 150 ° C., of the dehydration temperature of the dihydrate gypsum, and is fixed to the paperboard portion. When dehydrated into half-water gypsum, the gypsum content that has become hemihydrate gypsum is peeled off from the paperboard, and the peeled gypsum content is separated from the paperboard, so the crushed material of the heat-treated waste gypsum board By sieving the fine particles inside, the gypsum content can be removed, and the paperboard component can be obtained as a component on the screen. In the present invention, for example, the pulverized waste paperboard having a particle size of 5 mm or less is the waste gypsum board having a particle size of 50 mm or less. It collect | recovers and makes it a raw material for manufacture of a granular excrement disposal material.
In the present invention, the fine particles in the crushed paperboard waste crushed to a particle size of 50 mm or less and the pulverized paperboard waste pulverized to a particle size of 5 mm or less, most of the fine particles are hemihydrate gypsum. For example, it is preferable to classify and remove pulverized particles having a particle size of 1 mm or less, preferably 0.5 mm or less, using a sieve or an air classifier. The pulverized waste paperboard material thus separated has a hemihydrate gypsum content of 1 to 10% by weight and is used as a raw material for the production of granular excrement disposal materials. It is preferably 7% by weight. In the present invention, the pulverized paperboard waste has a particle size of 5 mm or less, but preferably has a particle size of 4 mm or less.

Or an organic fiber material waste pulverized material and a material having an adhesive property and a substance having a bactericidal action to form a composition for granulation, and this formed granulated composition The product can be formed by granulating into a granular material having a particle size of 1 mm or more in the presence of moisture. In the present invention, the organic fiber material waste pulverized product can be mixed in order to increase the water retention capacity and water absorption capacity of the granulated product and the granular core portion of the granulated product. In order to form a granulated composition having water retention ability and water absorption ability, that is, a composition for granulation, the organic fiber material waste pulverized material mixed with the paperboard waste pulverized material is a thin paper waste material pulverized product, hygiene Waste paper waste, Waste toilet paper waste, Tissue paper waste waste, Cosmetic paper waste waste, Dust paper waste waste, Paper cotton waste waste, Paper towel waste ground, Paper diaper waste ground, Animal paper diaper waste ground Waste, sanitary napkin waste, ground sweat pad waste, urine pad waste, toilet seat waste, magazine waste, magazine waste, buff powder, mechanical pulp waste, chemical pulp waste, semi-chemical Pulp waste, cotton-like pulp waste, wood pulp waste, waste pulp waste, paper powder, fluff pulp, water absorbent fiber waste, non-woven fabric waste, paper powder containing water absorbent resin, Paper powder generated during the manufacture of nonwoven fabrics, paper powder generated during the papermaking process or paper powder generated during the manufacture of sanitary materials, laminated paper waste material crushed material, laminated paper printing waste, laminated paper scraps, buff powder, Corrugated cardboard waste, newspaper waste, magazine waste, paper sludge, pulp sludge, tobacco filter non-standard product, tobacco packaging paper non-standard product, synthetic resin fiber waste material, wood waste product, wood waste product, wood powder, Home demolition material crushed material, new construction material pulverized material, paper powder, titanium paper waste material pulverized material, roasted coffee bean extraction residue, tea husk, vegetable waste, shochu, used ticket crushed material or punch waste, or two or more of these It can be set as the mixture containing. In the present invention, the waste material means a non-standard product, a defective product due to adhesion of dirt or the like, or a used waste. Waste refers to waste that is used for use or discarded as waste.

  In the present invention, an adhesive material is mixed in the granulated product so that the granulated product does not collapse. In the present invention, as an adhesive material, an adhesive, a water absorbent resin, or a mixture of two or more thereof is used. In the present invention, examples of the adhesive material include a paste such as α starch and a highly water absorbent resin such as sodium polyacrylate.

In addition, alcohol-soluble adhesive materials include hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), polyvinyl pyrrolidone, or (PVP). Or these 2 or more types can be mixed and used. Gelling agents such as gelatin and polyvinyl alcohol are preferable because they can form a granulated material having a granulated material having a particle size of 5 millimeters or less. In the present invention, as materials having adhesiveness, there are thickeners such as loin and bingham, tara gum, guar gum or xanthan gum. These thickeners can be used alone or as a material having adhesiveness together with a water-absorbing resin or an adhesive material or a water-absorbing resin and an adhesive material.

  In the present invention, the paperboard waste material contains 1 to 10% by weight of hemihydrate gypsum, so that granulation is possible without mixing an adhesive material into a granulated composition. However, it is preferable to add a material having adhesiveness to the composition to be granulated, since it can be granulated and hardened in a relatively short time. In this case, the amount of material having adhesion to the granulated composition can be mixed in an amount in the range of 10 weight percent to 1 weight percent. In this case, the material having adhesiveness can be increased or decreased within the above range according to the amount of hemihydrate gypsum contained in the pulverized waste paperboard. Thus, when the material which has adhesiveness is contained in the composition for granulation, it can be set as a hard granulated material, so that there is much content of the material which has adhesiveness. When the adhesive material is a water-absorbing resin, the water-absorbing resin has the property of absorbing water and expanding, so the amount of water-absorbing resin contained in the granular material in order to absorb water and avoid particle collapse. The blending ratio of the water-absorbing resin is, for example, 5% by weight or less, preferably 1% by weight or less, with respect to the granulating composition.

  In the present invention, a substance having a bactericidal action can be added to the granular material so that wrinkles can be prevented and stored for a long period of time. in this case. Examples of the substance having a bactericidal action include bactericides, fungicides or preservatives, or bactericides, fungicides and mixtures of two or more of the preservatives. In the present invention, such a substance having a bactericidal action does not decolorize the dried powdered plastic material having a particle size of 5 millimeters or less, or the dried powdered plastic material and the dried organic material waste product. It is preferable that it does not have a decoloring action. The substance having such a bactericidal action is preferably, for example, a food preservative and a bactericidal agent used for food preservation and sterilization. Examples of substances having such a bactericidal action include bactericides such as organic acids, sodium chloride, sorbic acid or salts thereof, calcium propionate, hinokitiol, and benzoic acid or salts thereof, preservatives and antifungal agents. In addition to this, an antibacterial agent can be used. In the present invention, the substance having a bactericidal action includes, in addition to the above, acetic acid, succinic acid, lactic acid, malic acid, citric acid, tartaric acid, adipic acid, benzoic acid, sodium benzoate, sorbic acid, potassium sorbate, dehydro Acetic acid, sodium dehydroacetate, propionic acid, sodium propionate, calcium propionate, hinokitiol, sodium hypochlorite, isobutyl paraoxybenzoate, isopropyl paraoxybenzoate, ethyl paraoxybenzoate, butyl paraoxybenzoate, propyl paraoxybenzoate, There is chlorine dioxide or salt, or a mixture of two or more of these.

  In the present invention, when the organic fiber material waste powder used as the granular excrement disposal material has an odor, the odor of the granulated product or the coated granular material by the organic fiber material waste In addition, the granulated or coated granule is sanitary and safe, or touched to give a dry feel, and does not generate wrinkles or unpleasant odors In order to achieve this, the granulated product or the coated granule is preferably dried so that the water content is 12% by weight or less, preferably 10% by weight or less, and more preferably 8% by weight or less. In order that the dried granulated product or coated granule does not generate dust or the like, the granulated product or granulated product for the coated granule is preferably formed into a granule having a particle size of 1 millimeter or more. . In addition, the dried granulated product or coated granular product is dried so that the odor of the pulverized organic material waste does not deteriorate the indoor environment and is hygienic and safe. Further, an additive substance, that is, a substance having a deodorizing action or a deodorizing action or a mixture thereof can be mixed with the granulated product or coated particle.

  When the granular excrement treatment material is a coated granular material, the granular core portion has weak water absorption, the water absorption of the excrement treatment material is mainly performed in the coating layer portion, and the water retention of the excrement treatment material is mainly performed. This can be done with a granular core. In this case, the granular excrement disposal material of the coated granular material in which the water-absorbing resin is blended in the coating layer portion is wet during excretion, and the wet coated granular particles that are in contact with each other adhere to each other via the water-absorbing resin. A clot is formed. At this time, if the content of the water-absorbent resin in the coating layer portion is 5% by weight or less, even a coagulum formed by adhesion of excrement disposal material particles formed wet when excreted is dispersed in water. be able to. Even if the water-absorbing resin is not used or used in the core, if the amount of the water-absorbing resin is reduced, the increase in the volume due to swelling of the core during water absorption can be reduced, and the granulated material can be destroyed and agglomerated. This is preferable because breakage of the lump can be avoided. In the coating layer portion, a part of the water-absorbing resin can be replaced with a material having adhesiveness such as a paste or other adhesive. If the water-absorbing resin content in the coating layer part is reduced and the amount of water-soluble or hydrophilic adhesive such as glue is increased, the adhesion between the particles of the granular excrement treatment material when wet becomes stronger, and adhesion The later dispersion function in water can be increased. In the present invention, as the water-absorbent resin, a separation product rich in the water-absorbent resin separated by a dry or wet classification treatment can be used. In this case, the separation product rich in the water-absorbing resin separated by the dry treatment is retained without impairing the water-absorbing ability as compared with the separation product rich in the water-absorbing resin separated by the wet treatment. Is preferable. When a water-soluble adhesive is contained in the granular core, when the core surface is wetted with water, the adhesive in the core diffuses to the surface, and the paper powder of the coating layer is transferred to the core surface. The coating layer is preferably adhered to the substrate, so that the deposition of the coating layer can be stabilized and peeling of the coating layer after drying can be prevented.

  In the present invention, the granulation composition is mixed with water necessary for granulation prior to granulation. In the present invention, the granulation is performed by, for example, a screw-type extrusion granulation apparatus that granulates with relatively high moisture, a disk-type extrusion granulation apparatus such as a disk pelleter that granulates with relatively low moisture, or roll-type extrusion granulation. It can be granulated by an apparatus or a ram type extrusion granulator. When granulating with a screw-type extrusion granulator, water is mixed in the granulating composition so that 25 to 50 weight percent of water is contained, but a disk-type extrusion molding such as a disk pelleter. In the case of granulating with a granulating device or a roll type extrusion granulating device, it is sufficient that the granulating composition contains 10 to 25 percent by weight of water.

  The water necessary for this granulation is performed by adding water from the outside to the granulated composition. When supplying water necessary for granulation, the water-absorbing water-absorbing resin contains a considerable amount of water together with the water-absorbing resin. Therefore, a water-containing water-absorbing resin is used instead of the water-absorbing resin and water to be supplied. be able to. As such a water-containing water-absorbing resin, there is a water-containing regenerated water-absorbing resin of a separated product obtained by wet separation. The water-containing recycled water-absorbing resin is a water-containing water-absorbing resin obtained by collecting the used water-containing water-absorbing resin without dehydration.For example, the pulp is obtained from the used waste material such as used sanitary goods by wet classification. The water-absorbing water-absorbing resin separated and recovered. Since the water-containing recycled water-absorbing resin contains a considerable amount of water together with the water-absorbing resin, it is possible to supply water necessary for granulation and water-absorbing resin necessary for the granulated product. When the water necessary for granulation is supplied by the water-containing regenerated water-absorbent resin, the water contained in the water-containing regenerated water-absorbent resin is added by mixing the water-containing regenerated water-absorbent resin. Therefore, when the water-containing regenerated water absorbent resin is used, the amount of water supplied from the outside to the granulated mixture can be reduced by the amount of water contained in the water-containing regenerated water absorbent resin. Thus, in the case of a granulated mixture containing a water-containing recycled water-absorbing resin, the water-containing recycled water-absorbing resin contained functions as a lubricant in the extrusion granulation process, and the water-containing recycled water-absorbing water contained therein. The water absorption ability after dehydration of the resin is preferable because the granular excrement disposal material exhibits a water absorption function and / or a water retention function.

  In the present invention, the water-containing regenerated water-absorbing resin mixed in place of water in granulation contains water in an amount of 50 times or more, preferably 300 times or more, more preferably 500 times or more of its own weight. One or two or more water-containing regenerated water-absorbing resins can be obtained, and the water-containing regenerated water-absorbing resin that has absorbed a large amount of water in this way exhibits a gel-like or viscous liquid. In particular, the greater the amount of water contained, the more water-containing regenerated water-absorbent resin becomes a liquid gel, which can be handled in the same way as a liquid. As with the liquid, it can be carried out using a watering device or a spraying device, for example, which is preferable.

  In the present invention, when the water-containing regenerated water-absorbing resin is used for adding water to the granulating composition, the blending amount of the water-absorbing resin in the granulating composition depends on the use of the water-containing regenerated water-absorbing resin. It can reduce according to the residual water absorption capacity of the added water absorbing resin. The water-absorbing resin contained in the granulating composition exhibits a lubricating action during granulation. Even when the water-containing regenerated water-absorbing resin is used instead of water, the water-absorbing resin contained in the water-containing regenerated water-absorbing resin is used. Since the resin exhibits a lubricating action, the content of the water-absorbing resin in the granulating composition is, for example, 1% by weight or less, preferably 0. It can be 1% by weight or less, more preferably 0.05% by weight or less. In this way, the granular excrement treatment material with a small amount of the water-absorbing resin in the core part is wet during excretion and adheres to each other at the particle coating layer part to form a coagulum.

A dry coated granular material having a coating layer portion to be used, and since a paperboard waste material crushed material having a hemihydrate gypsum component adhering amount of 10% by weight or less is used, the gypsum component adhering to the paperboard is hemihydrate gypsum. Since the water-absorbing performance of the paperboard contains hemihydrate gypsum, the water retention of the core can be improved, and the hemihydrate gypsum intervening between the paperboard particles and the organic fiber material particles is a granulated mixture. It contributes to adhesion between particles and can prevent the granulated material from collapsing as much as possible. Moreover, the present invention recovers the paperboard that has been discarded because it is difficult to separate the gypsum from the waste gypsum board, and effectively uses it as a raw material for the granular excrement disposal material. Since it is possible to provide an inexpensive granular excrement disposal material having water retention and water absorption capabilities, it contributes greatly to the industry.
