Yes, from the field of manufacturing and using such continuous porous particles, as well as from the field of providing and selling equipment and instruments necessary for its transportation, storage, assembly and use, these materials and machinery , Fields that provide materials necessary for parts, such as wood, stone, various fibers, plastics, various metal materials, etc., fields of electronic components incorporated in them, and control-related equipment that integrates them, various measuring instruments Fields generally referred to as industrial machines, such as the field of power machines that move the equipment and equipment, the electric power that is energy and the energy source, the field of oil, In addition to testing and researching these facilities and instruments, in the fields related to their display, sales, import and export, as well as the results of their use and the operation of the facilities and instruments to create them There are no technical fields that are not related to the fields related to the collection and transportation of generated garbage, the recycling field for efficiently reusing these wastes, and new fields that cannot be envisaged at this time.

(Points of interest)
Aquariums for breeding ornamental fish are usually gradually added after about 4 to 5 days at a water temperature of around 20 degrees Celsius, even when a new aquarium is newly installed or when new water is thoroughly washed and replaced with new water. Algae begin to develop, especially in places where direct sunlight enters, because algae photosynthesis is further promoted and proliferates rapidly, so general ornamental fish enthusiasts are always in dark places where they are not exposed to sunlight In addition, there is a drawback that it is necessary to raise and maintain the aquarium, and it is necessary to frequently replace and wash the water in the aquarium.

(Conventional technology)
Considering such a situation, for example, an antialgal composition containing 1 to 100 ppm of a germanium compound and 0.001 to 0.2 ppm of a herbicide as represented by the one proposed in Patent Document 1 (1) below. By adding low-concentration herbicides to the aquatic animal breeding water, the generation or growth of algae breeding in the aquatic animal breeding water is suppressed or prevented, and it is safe without toxicity to aquatic animals. The supply device is connected to a carbon dioxide containing body that contains carbon dioxide, as shown in Patent Document 1 (2), and carbon dioxide is supplied from the supply device to the water in the water tank. In an ornamental aquarium device that is supplied and diffused, a deodorant obtained by adsorbing a water-soluble substance mainly composed of tannin on natural zeolite is mixed as a mixing agent in the carbon dioxide container. Such as ornamental aquarium equipment is scattered made.

    However, deodorizing can be applied to chemicals to which the antialgal composition is added directly to the water tank as shown in the former Patent Document 1 (1), to the air filter of the water tank of Patent Document 1 (2), or to the air supply path. Or the thing which contained the mixture which has a water quality improvement effect has the characteristic that all are excellent in the immediate effect of the suppression effect of algae, but the effect is lost in about 3 weeks, After that, there is a disadvantage that it does not change as usual and begins to generate algae, and the user changes the water in the aquarium once a month as a guide and the aquarium and each part once every 3 to 6 months It has not been possible to drastically reduce the frequency of troublesome tank cleaning.

    Moreover, as what can make the anti-algal effect of the anti-algal composition thrown into the water tank sustainable in the long term, for example, as in Patent Document 1 (3), it has a spherical space inside the ceramic spherical shell, The spherical space filled with a liquid, a gas body, and a substance selected from the group consisting of a solid that becomes liquid or gas at high temperature, and antibacterial substances such as those found in the latter patent document 1 (4) Inclusion of water-soluble and highly volatile functional substances such as underwater biological adhesion inhibitors, fragrances, and agricultural chemicals, and inorganic porous fine particles coated with polymer materials such as proteins, polysaccharides, and synthetic resins .

However, as in these Patent Document 1 (3) and Patent Document 1 (4), the granular material encapsulating the functional substance in the hollow portion in the ceramic spherical shell is the functional substance enclosed, Although it is possible to delay the rate of elution or diffusion to the outside, the technology for injecting functional substances into the ceramic spherical shell is completely unknown, and when injected into water, the specific gravity is light and floats in water. However, until now, there has been no technology that has been developed so far that can appropriately set the properties of floating and sedimentation of granular materials in water.

(Awareness of problems)
As mentioned above, the various chemicals and aquarium devices that have been proposed so far have immediate effects on the effects of preventing the generation of algae and suppressing growth, but the effects are not sustainable, There is a fatal drawback that the frequency of cleaning cannot be greatly reduced, and there is no algae control technology that can prevent the generation of algae even after one month.

    In addition, a granule in which a functional substance such as an algae inhibitor is sealed in a hollow portion of the ceramic granule has been proposed as a means for suppressing the generation of such algae in the long term. In fact, technologies that encapsulate functional substances in granular bodies, technologies that can float on the surface of the water or in water, or technologies that can settle on the aquarium floor have not been developed yet. It was.

(Object of invention)
In view of this, the present invention makes it possible to efficiently enclose a functional substance inside an unglazed granule made of a continuous porous outer shell, and to float on the water surface or in water, or on a floor such as a water tank. Judging whether it is possible to develop medicinal granule technology that can be sprayed in a sedimentary state, we have begun to develop and research it quickly, repeating trial and error over many years, and many trials and experiments. As a result, the present invention has finally succeeded in realizing the algae-suppressing grains having a novel structure and a novel production method thereof. It will be described in detail.

(Structure of the invention)
As will be clearly understood from the examples representing the present invention shown in the drawings, the algal control grain of the present invention basically comprises the following constitution.
In other words, in an appropriate three-dimensional shape with a predetermined hollow portion secured therein, a part or all of it is an unglazed granule composed of an outer shell portion made of a continuous porous material composed of countless nano-sized pores, From the injection hole provided at a suitable position of the outer shell portion, when any one or all of the components of the functional drug react with the permeation liquid, the desired active ingredient is communicated to the outer shell portion. porous whether the immersion liquid through the micropores have, or, on a predetermined amount to allow release in at least one of fluid or in a given gas was to be loaded with respect to the hollow portion, the injection The hole is filled and / or concealed with an insoluble material selected from materials consisting of adhesives, paint coatings, resin adhesive seals, or combinations thereof with specific gravity greater or smaller than the specific gravity of the unglazed grains. , Against unglazed grains when submerged in water That the arrangement positional relation between the insoluble material was made as may be selected a medicinal leaching grains and gist.

In other words, it is an appropriate three-dimensional shape in which a predetermined hollow portion is secured, and a part or the whole is unglazed made of an outer shell portion that is a continuous porous structure consisting of numerous nano-sized micropores. From the injection hole provided at a suitable position in the outer shell portion of the granule, when any one or all of the components of the functional drug react with the permeate, the desired active ingredient is A predetermined amount that can be discharged into the immersion liquid or at least one of a predetermined gas through the microporous pores of the outer shell portion is loaded into the hollow portion . In addition, the injection hole is made of an insoluble material selected from a material composed of an adhesive, a paint film, a resin adhesive seal, or a combination thereof having a specific gravity larger or smaller than the specific gravity of the unglazed grains. filling and / or concealed, when submerged Positional relationship between the insoluble material for unglazed granules are adapted to select a predetermined active ingredient in encapsulated form and the functional agents into the hollow portion, releasable and regulations in its outside through only the fine holes of the outer shell It can be said that it is a medicinal leaching grain composed of the composition.

(Related invention)
In relation to the above-described medicinal leaching grains, the present invention also includes a method for producing medicinal leaching grains having the following constitution.
In other words, the disappearance model that modeled the hollow part of a predetermined capacity is covered with a firing material and formed into an appropriate three-dimensional outer shell part, and the disappearance model disappears in the process of heating to an appropriate temperature. After forming an unglazed granule having a hollow porous portion and a continuous porous outer shell portion obtained by firing and curing the firing material, the unbaked granule outer shell portion is perforated at an appropriate place in the hollow portion. A continuous injection hole is formed and a predetermined amount of the functional drug is filled into the hollow portion through the injection hole, and the functional drug is encapsulated by filling and / or concealing an insoluble material in the injection hole. This is a method for producing the medicinal leaching grains that forms the basis of the present invention.

    If this production method is expressed in different expressions, the firing material is appropriately formed into a three-dimensional shape, fired to form a continuous porous unglazed granule, and then the unglazed granule is bored to connect to the injection hole. After drilling a hollow portion of a predetermined depth, the hollow portion is filled with a predetermined amount of a functional drug through an injection hole, and then filled with and / or concealed with an insoluble material in the injection hole. Thus, the medicinal leachable grain manufacturing method which forms the basis of the present invention is obtained.

    As described above, according to the medicinal effect leachables of the present invention, unlike the conventional ones, a part or all of the unglazed granule containing the functional drug is nano-sized from the unique characteristic configuration as described above. It consists of a continuous porous outer shell composed of countless micropores, and when it is put into water, the active ingredient of the functional drug is slowly added to a liquid such as water that permeates the outer shell. It will be released, and it will be possible to generate both the immediate effect of the functional drug and the long-lasting effect, and the injection hole shall be filled and / or concealed with an insoluble material. As a result, it is possible to reliably prevent the chemical agent from being melted or leaked, and to obtain an excellent feature that a stable quality can be maintained over a long period of time.

    In addition, the predetermined amount of the functional drug filled in the hollow portion is adjusted to a weight adjusted so that the total specific gravity of the functional drug is equal to 1 with the unglazed grains, the insoluble material filled and / or concealed in the injection hole, and the functional drug. What is set, when the medicinal leaching particles are put into water, it can be suspended in water, and the predetermined amount of the functional drug filled in the hollow portion is unglazed granules, Insoluble materials filled and / or concealed in the injection hole, and those set to a weight adjusted so that the total specific gravity of the functional drug is more than 1 and less than 20, when the medicinal leachables are put into aquarium water In addition, the predetermined amount of the functional drug filled in the hollow portion may be undissolved material filled and / or concealed in the injection hole. In addition, when the total specific gravity of the functional drug is set to a weight adjusted so as to be 0.1 or more and less than 1, when the medicinal leachable particles are poured into water, It becomes a floating thing and has the outstanding advantage that the specific gravity can be adjusted according to various uses.

    In addition, the unglazed granule has a spherical shape having an outer diameter of 2 cm or 4 cm, and any functional drug cannot pass through the nano-sized micropores of the continuous porous outer shell. Active zeolite 50-50%, polyaluminum chloride 10-5%, activated carbon powder 0.1%, silver 3-5%, copper 5-10% An algal inhibitor containing 30 to 35% zinc and 0.1 to 0.05% sulfur, and 2 g of the unbaked granule having an outer diameter of 2 cm is filled with 2 g of the algal inhibitor and the outer diameter is 4 cm. The unglazed granule is algae-suppressed granule filled with 4 g of the algae-suppressing agent, and fluid outside the unglazed granule is also present between the powders of the algae-suppressing agent filled in the hollow part and between the granules. What can be infiltrated will be algae-suppressed when thrown into water The active ingredient of the agent is released into the water continuously over a long period of time, making it possible to prevent the generation of algae over a long period of time, greatly reducing the frequency of tank cleaning and water replacement, This has the advantage that the particle size and number can be freely selected and adjusted according to the size and amount of water in the water tank.

    Then, the outer diameter of the unglazed granule is either 2 cm or 4 cm, and the functional drug is 2 g or 4 g of wax, and water-insoluble fragrance is 0. 1 to 2% added fragrance, 2 g of the unglazed granules having an outer diameter of 2 cm are filled with 2 g of the fragrance, and 4 g of the fragrance having an outer diameter of 4 cm are filled. In the case where the fragrance agent filled in the hollow portion is filled with the wax so that there is almost no gap, the water penetrated into the unglazed granule when mixed in the water is mixed with the wax. The fragrance agent is eluted and evaporated directly through the nano-sized micropores in the continuous porous outer shell of the unglazed granule or through at least one of the water surface for a long period of time. Outstanding feature of being aromatic It can be.

    Further, the functional agent is an aromatic agent in which 0.1 to 2% of a water-insoluble fragrance is added to either 2 g or 4 g of wax, and the same is applied to the hollow portion of the unglazed granule. A predetermined amount of melted and liquefied wax component and fragrance of the fragrance agent is filled in the hollow portion, and the fragrance particles are hardened in a lump and contain the fragrance agent in a state where the wax is cured. Compared to the above, it is possible to easily fill the hollow part with the wax component and the fragrance of the fragrance agent without gaps, and to improve the production efficiency, and to reduce the amount of water immersed in the hollow part. It is possible to set it so that the specific gravity of the whole medicinal leachable grains can be easily reduced and floated on water.

    The medicinal leachable grains in which the insoluble material filling and / or concealing the injection hole is made of a material having a specific gravity larger than that of the unglazed grains are affected by the buoyancy generated when thrown into water and the action of gravity. Be sure to automatically control the posture so that the injection hole filled and / or concealed with the insoluble material faces vertically downward, enabling the active ingredient of the functional drug to be released from countless micropores. As compared with the case where the continuous porous outer shell portion is directed upward and the outer shell portion faces downward, the release efficiency of the active ingredient can be greatly improved.

    And, according to the method for producing medicinal leached grains of the present invention, the hollow part can be automatically formed in the firing material during the firing process of the unglazed grains using the disappearance model. The process of machining the material becomes insoluble, the manufacturing man-hours can be greatly reduced, and mass production can be made efficiently and inexpensively. Manufacturing that is set to pierce the hollow portion has an excellent effect of simplifying the molding process, greatly improving production efficiency, and manufacturing in large quantities at low cost.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.
The unglazed granule is a continuous porous material in which the outer shell of the medicinal leachable particle is insoluble in water and has sufficient strength, and part or all of it is a continuous porous material having numerous nano-sized micropores. And fulfills the function of ensuring a predetermined hollow portion in the inside, and immerses the active ingredient of the functional drug loaded in the hollow portion through the micropores in the outer shell portion as a continuous porous material. It must be capable of being released into a fluid or at least one fluid in a given gas and has an outer diameter of 2 cm or 4 cm as shown in the examples described later. It is desirable that either one of ceramic clay or glass firing material is molded and fired, and the three-dimensional shape is not spherical, Oval, cylinder, cube, cuboid, cone , Polygonal pyramids and other polyhedrons, abacus pearls, irregular pebbles, dolls, animals, plants, vehicles, buildings, etc. Further, the outer shell portion can be colored or dyed.

    The hollow part is formed inside the unglazed granule and cannot leak a predetermined amount of the functional drug, and the active part is in the immersion liquid through the infinite number of micropores in the outer shell part which is a continuous porous material, or , Fulfills the function of being able to be stored in a sealed manner so that it can be released into at least one of the fluids in a predetermined gas, and a part of which has an injection hole provided at an appropriate position in the outer shell portion. As shown in the examples to be described later, it is formed as a space portion of a predetermined capacity connected to an injection hole opened in a part of the outer shell portion inside the unglazed grains. In addition, it is possible to form the bottomed hole with a predetermined depth by boring the unglazed grains, and the shape is not particularly limited. , To secure a capacity that can be filled with a predetermined amount of functional medicine Well, the capacity can be appropriately set according to the filling amount of the functional drug. For example, when the amount of water is 10 L, the total amount is 2 g according to the capacity of the water tank to be charged. Is 20 L, it can be set to have an internal volume that can accommodate 4 g.

    The injection hole fulfills the function of allowing the functional drug to be poured when a predetermined amount of the functional drug is filled in the hollow portion. The functional drug must be set to a shape and size that can be filled efficiently and easily, for example, as shown in the examples described later, formed into a cylindrical inner peripheral wall shape It may be desirable to have a funnel-shaped inner peripheral wall shape.

    When the functional drug is filled in the hollow part and the injection hole is filled and / or concealed with an insoluble material, it does not leak out from the hollow part, and the nano-sized innumerable nano-sized parts of the continuous porous outer shell part. When it comes into contact with liquid or gas that has permeated into the hollow part from the micropores, it functions to release the desired active ingredient over a long period of time, and can be used as various drugs and fragrances. As shown in the examples below, active zeolite 50 to 40%, polyaluminum chloride 10 to 5%, activated carbon powder 0.1%, silver 3 to 5%, copper 5 to 10%, zinc 30 to 35%, A fragrance agent prepared by adding 0.1 to 2% of a water-insoluble fragrance to an algae-suppressing agent mixed with 0.1 to 0.05% of sulfur, or 2 g or 4 g of wax. To do Can.

In addition, the functional drug has a total specific gravity of 1 as appropriate depending on the purpose of use, and a predetermined amount to be filled in the hollow portion is an unglazed granule, an insoluble material filled and / or concealed in the injection hole, and the functional drug. In addition to the weight adjusted to be equal, the total specific gravity may be set to a weight adjusted to exceed 1 and less than 20, or the total specific gravity may be set to 0. It may be set to a weight adjusted to be 1 or more and less than 1.
It is technically very difficult to select and adjust the components of the functional drug so that the total specific gravity is set to more than 20 and less than 0.1, and there are few practical advantages. It is desirable to eliminate this.

Algae control drugs are drugs that can prevent the generation and growth of algae that occur in various waters such as water storage in water tanks and tanks, and running water in waterways and pipes, and are harmless depending on the purpose of use. Must be appropriately selected and adjusted so that, for example, sulfate band, zinc oxide, Ag zeolite, copper oxide, cation, iodine, magnesium, iron, calcium, active zeolite, polyaluminum chloride, activated carbon powder, Materials or drugs that exhibit various actions such as adsorption of impurities such as silver, copper, zinc and sulfur, blocking of dust, absorption of odors, antibacterial, sterilization, removal of nitrous nitrite, alone or as appropriate A mixture of the algae-suppressing agent filled in the hollow part and a gap between the powder and the granule so that fluid outside the unglazed granule can penetrate into the hollow part. It can be.
Further, it is possible to use a mixture of a water-absorbing polymer, CMC (carboxymethylcellulose), vinyl acetate, a flocculant and the like so that the weight and specific gravity can be adjusted while the immersion liquid is absorbed.

    Fragrance is an oily substance with a high melting point, which is made by adding an appropriate amount of a water-insoluble fragrance to a wax such as a higher fatty acid or neutral fat. The fragrance comes into contact with various liquids or air. It must be fragrant and insoluble in water, can be made into various natural and synthetic fragrances, and can be made into essential oils and / or resins extracted from plants. As shown in the above, 0.1 to 2% of a water-insoluble fragrance is added to either 2 g or 4 g of wax, and the wax component of the fragrance agent and A predetermined amount of the fragrance melted and liquefied can be hardened into a lump so as to fill the inside thereof with almost no gap.

The insoluble material can be sealed so that the functional drug does not leak from the injection hole, and can be sealed so that liquid or gas does not flow into the hollow portion through the injection hole, and is filled and concealed in the injection hole. Or, it should be possible to either fill or conceal, fill the injection hole with insoluble material, provide a seal or coating layer made of insoluble material in the injection hole, Or it can depend on both of them, and more specifically, an adhesive, a paint film, a resin adhesive seal, or a combination thereof.
In addition, as shown in the examples described later, the insoluble material filling and / or concealing the injection hole can be made of a material having a specific gravity greater than that of the unglazed grains, The insoluble material can be made of a material having a specific gravity smaller than that of the unglazed grains.

    The method for producing medicinal leachable grains enables efficient mass production of medicinal leachable grains such as algae-suppressed grains and aromatic grains. For example, an unglazed granule having an injection hole and a hollow portion using a disappearance model A manufacturing method that enables easy molding and firing, and a manufacturing method in which a hollow portion having a predetermined depth connected to the injection hole is formed by boring the fired unbaked granule. In the step of filling the hollow part with the functional drug, the melted and liquefied functional drug can be filled into the hollow part, and the injection hole is filled and / or concealed with an insoluble material. In the process, the injection hole is filled with an adhesive and cured, or a resin coating is applied to the surface of the functional drug exposed in the injection hole and dried to form a paint film, or the injection hole is formed. Resin adhesive seal Wearing or, or, like them to fill and / or hide the insoluble material in the injection hole to combine back and forth, can be by various settings.

The disappearance model is a stage in which the firing material before firing processing is appropriately formed into a three-dimensional shape, and allows a predetermined hollow part to be formed in the firing material granule, and during the firing process of the granule It has the function of disappearing and must have a strength that can withstand the pressure of granulation molding and a melting point that easily disappears at the temperature at which the unglazed granule is fired. As shown in the example, it can be made of foamed synthetic resin or wax that melts and evaporates at the firing temperature of the unglazed granule.
In the following, the structure of the present invention will be described in detail together with an embodiment representative of the present invention shown in the drawings.
