In particular, there is high expectation for the effective use of useful resources with excellent physical properties.

  One useful resource with outstanding physical properties is the insulators that are commonly used for electrical insulation in power transmission facilities such as telegraph poles and transmission towers and related substation facilities. For the insulator, a sintered sintered body manufactured under extremely severe conditions in terms of physical properties such as a reducing atmosphere at 1300 ° C. is used because of functions, safety and reliability required for the purpose of use. Depending on the production conditions, the insulator has a dense structure with a water absorption rate of 0%, so its hardness and wear resistance are extremely high, and it is also excellent in chemical resistance as typified by acid resistance and alkali resistance. In addition, since there is no change in physical properties semipermanently, it has a remarkable property that almost no secular change is observed.

  Thanks to the unique properties typified by the outstanding physical property stability of these insulators, there is no chemical or physical means to properly dispose of the used insulators as waste even if they are recovered. There was no reusable technology. Despite the rare and remarkable qualities of the collected used coconuts, a huge amount collected every year is dumped as landfills, etc., in a state of being collected as mere waste without regenerating new value. It had been.

  Therefore, the applicant of the present application has proposed a method for producing a porous sintered body made of insulator waste material for reuse of insulator waste material (Patent Document 3).

  The previous proposal is a step of pulverizing the cocoon waste material using the cocoon waste material as a starting material, a step of classifying the pulverized material, a step of preparing a molding material containing the pulverized product, and then kneading, molding the kneaded material A container-like porous sintered body having a predetermined porosity and a structure in which the insulator grain portions are joined to each other by the molten layer through the process and then the molded product firing process were obtained.

  As a result, greening substrates made of porous sintered bodies and marine algae-attached substrates that take advantage of the characteristics of porous sintered bodies that are lightweight and have air gaps, air permeability and water permeability. We were able to provide various practical products with economic value as valuable materials from the waste palm material, and provided an effective means for recycling the waste palm material.

  Ceramics such as tea bowls and vases, refractory bricks, and natural igneous rocks such as quartzite and feldspar mixtures represented by porcelain stones and mackerel are also useful resources with excellent physical properties like the above-mentioned insulators. is there.

  However, low-grade raw materials other than those used as natural ceramics raw materials, rejected products in the ceramic manufacturing process, and ceramics such as teacups and vases that have been discarded are effective. Utilization technology was not established. In addition, regarding refractory bricks, no effective utilization technology has been established so far for products that are rejected in the manufacturing process or products that are discarded due to removal.

  For this reason, the effective use of these products that were rejected in the manufacturing process and those that were subject to disposal due to removal, etc. was small, and a huge amount remained unused every year, Was dumped as.

  In this way, the kneaded product is made into a predetermined shape (for example, a plate-like body having a size of 600 cm × 600 cm × 60 cm (thickness), a cylinder having a bottom diameter of 300 mm × a height of 200 mm, a cone having a bottom diameter of 300 mm × a height of 200 mm, and a bottom diameter of 300 mm × high. 200 mm square pyramid and hexagonal pyramid). In addition, in these cones, quadrangular pyramids, and hexagonal pyramids, the ones in which grooves extending radially from the apex portion toward the bottom edge were formed on the peripheral wall were molded.

  Further, in the kneaded product forming step, during the wet state in which the organic binder has adhesive strength, as described above, the particle size does not exceed 300 microns and is sized within a predetermined particle size range. The ceramic particles thus formed were sprinkled over the entire surface of the kneaded product formed into the predetermined shape.

  That is, a kneaded product in which alumina pulverized particles classified to a particle size of 6 microns or more and less than 8 microns are formed into the predetermined shape during a wet state in which CMC (carboxymethylcellulose) has adhesive strength. I sprinkled all over the surface of the object.

(Kneaded product firing)
Finally, in the molded product firing step, the kneaded product molded into a predetermined shape with ceramic particles coated on the entire surface is dried, and then fired at 1000 to 1500 ° C. to form a porous sintered body. The seaweed fixing base for algal reefs of the present invention is produced.

  Here, the kneaded material having the above-mentioned shape in which the pulverized alumina particles were coated on the entire surface was dried and then fired at a temperature range of 1000 to 1500 ° C. for 12 hours. In addition, a baking process can be adjusted in 9 to 13 hours.

  In this way, the seaweed fixing base for algal reef of the present invention comprising the porous fired body indicated by reference numeral 40 in FIGS. 12 (a) to 12 (c) and indicated by reference numeral 41 in FIGS. 13 (a) and (b) was manufactured. . The seaweed fixing base 40 (FIGS. 12A to 12C) for algae reef has a hexagonal pyramid shape. The seaweed anchoring base 40 for algae reef (FIGS. 13A and 13B) has a conical shape, and in the conical body, there are six grooves 42 extending radially from the apex to the bottom edge. It is formed on the peripheral wall.

  In the seaweed fixing bases 40 and 41 for algal reefs of the present invention comprising this porous fired body, as shown in FIGS. 12 and 13, the ceramic pulverized material, the cocoon pulverized material, the refractory brick pulverized material, and natural Ceramic particles (not shown) are welded to the surface of the igneous rock pulverized particles by a firing process and then solidified with natural vitreous minerals.

  In the seaweed fixing bases 40 and 41 for algal reefs of the present invention made of a porous sintered body, natural vitreous minerals are melted by the firing step and then solidified, whereby FIGS. 12 (a) to (c). 13 (a) and 13 (b), a gap is formed as indicated by reference numeral 5, and this plays an advantageous role in the establishment and growth of seaweed seeds, spores, seaweed temporary roots and roots.

  Moreover, the size of the gap 5 is larger than that in Example 1 because the particle size of the ceramic pulverized product, the insulator pulverized product, the refractory brick pulverized product, and the natural igneous rock pulverized product is larger than that in Example 1. It becomes.

  Also in this embodiment, the surface of the seaweed fixing bases 40 and 41 for algal reefs of the present invention made of a porous sintered body is sized within a predetermined particle size range with a particle size not exceeding 300 microns. The ceramic particles are attached.

  Also, the seaweed fixing bases 40 and 41 for algal reefs of the present invention made of a porous sintered body have innumerable fine pores (voids) inside thereof, as in the case of Example 1. .

  As a result, when seaweed seeds and spores are attached to the surface of the seaweed colony base for algae reef, a good colonization rate can be obtained, and further, temporary roots and roots of the growing seaweed are easily settled.

  Moreover, since the seaweed fixing base for algal reefs of this Example is manufactured from the raw material mentioned above, there is no possibility that a soluble alkali content elutes like the seaweed fixing base for algal reefs of Example 1.

  The seaweed settlement base for algal reefs of this example was useful as a settlement base for various seaweed cultures including kelp and seaweed.

  Particularly in the case of this example, a pulverized material such as ceramics having a particle size of 2 mm or more and less than 3 mm, 3 mm or more and less than 5 mm, 5 mm or more and less than 10 mm, 10 mm or more and less than 20 mm, and 20 mm or more and less than 40 mm is used as a raw material. As a result, the large gaps 5 are formed more complicatedly than in the case where the pulverized material such as ceramics in the range of 300 to 20000 microns in Example 1 is used as the raw material. And since the grind | pulverized material of the range of particle size 2-40mm is used, the location sharply sharp-angled on the surface including the part which faces the space | gap part 5 became a very many thing.

  In the case of the seaweed anchoring bases 40 and 41 for the algal reefs of Example 2, compared to the seaweed anchoring bases for the algae reefs of Example 1 described above, the prevention of adhesion of barnacles, etc., and the damage caused by algal food snails and sea urchins, etc. The prevention effect was even higher. This seemed to be a result that the surface including the portion facing the gap portion 5 had very many sharp points.

  Thus, in the case of the seaweed fixing bases 40 and 41 for algal reefs of Example 2, the effect of preventing adhesion of barnacles and the like, and the prevention of food damage by algal-eating snails and sea urchins are high. The seaweed fixing bases 40 and 41 for algal reefs made of a porous fired body formed into a conical shape or a polygonal pyramid shape are described in Examples 1 and 2 as described in Examples 3 and 4 below. It is used by being mounted on the seaweed fixing base for algal reef of the present invention comprising the produced flat porous fired body, or it is mounted on a structure, which is used in Example 1 or Example 2.

  In the case of the seaweed settlement base for algal reef of the present invention of Example 2, by selecting the particle size range to be used for the ceramic pulverized material, the cocoon pulverized material, the firebrick pulverized material, and the natural igneous rock pulverized material, It is possible to provide a seaweed colony base that provides a suitable growth environment for seaweeds that prefer a base with a coarse particle size and seaweeds that prefer a base with a relatively small particle size. Thereby, the efficiency of seaweed colonization can be increased.

  The particle size range of one or more of ceramic pulverized material, cocoon pulverized material, fire brick pulverized material, and natural igneous rock pulverized material is 2 mm or more and less than 3 mm, 3 mm or more and less than 5 mm, 5 mm or more and less than 10 mm A seaweed colony base for algae reef using one or a combination of two or more, and one or more of ceramic pulverized material, coconut pulverized material, refractory brick pulverized material, natural igneous rock pulverized material The particle size range of 10 mm or more and less than 20 mm, or 20 mm or more and less than 40 mm, is formed by continuously arranging a seaweed colony base for algae using one or a combination of two or more kinds The seaweed settlement base for algae reefs.

  FIGS. 13C and 13D illustrate an example of this. As described above, the seaweed fixing base 40 for algae reef is of a conical shape, and has six grooves 42 extending radially from the apex to the bottom edge of the cone. When forming (FIGS. 13A and 13B), the portion indicated as “coarse particles” in FIGS. 13C and 13D has a particle size range of 10 mm or more and less than 20 mm, 20 mm Molding was performed using one or a combination of plural kinds less than 40 mm. 13 (c) and (d), the portion indicated as “fine particles” is a type having a particle size range of 2 mm or more and less than 3 mm, 3 mm or more and less than 5 mm, or 5 mm or more and less than 10 mm. Molding was performed using a combination of a plurality of types. Then, these are continuously arranged as shown in the figure, and have a conical shape. In the conical body, six grooves 42 extending radially from the apex portion toward the bottom edge are formed on the peripheral wall. The seaweed fixing base 40 (FIGS. 13A and 13B) for algae reef is formed.

  Some seaweeds may prefer a base with a relatively coarse particle size or a base with a relatively fine particle size at the growth stage. In such a case, the seaweed colonization base of the portion indicated as “fine particles” in FIGS. 13 (c) and (d) is suitable for seaweeds that prefer a base with a relatively fine particle size, FIG. 13 (c), The portion of the seaweed colony that is indicated as “coarse particles” in (d) is suitable for seaweeds that prefer a substrate with a relatively coarse particle size.

  The preferred embodiments and examples of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to such embodiments and examples, and can be understood from the description of the claims. It can be changed into various forms within the scope.

  The range of coastal areas is narrowed nationwide by concrete revetments and wave-dissipating blocks. In addition, changes in the sea environment (for example, the progression of the burning phenomenon) have become a serious problem. There is no effective means to deal with these problems, the decrease in seaweed beds has become remarkable, and the coastal environment has deteriorated, resulting in an increase in catch reductions that may have been caused by this.

  In order to cope with the decline in coastal seaweed beds, the deterioration of the tidal flat fishing ground environment, and the decline in productivity, it is necessary to effectively restore seaweed beds that emphasize the preservation of the marine environment and ecosystem.

In other words, including the improvement of the environment such as CO ₂ absorption effect, the establishment of a systematic recreational technique for seaweed beds by introducing new technologies, such as the construction of seaweed beds on artificial revetments and sand mud areas such as firewood and concrete. It has been.

  In response to these problems, various fish reefs have been developed and installed in the sea, but the main purpose is to collect a large number of commercial fish. In many cases, adhesion of seaweed and the like has not been sufficiently considered. In addition, there has been a demand for efforts to actively revitalize spawning and fry rearing areas in fisheries.

  Examine the function, structure, and shape of algae and fish reefs that match the natural conditions of the sea area, produce small algae and fish reefs that can be expected to produce synergistic effects, and actively promote the creation and regeneration of seaweed beds that match the sea area. Therefore, it is requested to aim at environmental restoration of coastal sea area.

  The seaweed colonization base for algal reefs of the present invention is the basis for the establishment of seaweed, which is the basis of the place where organisms proliferate again, such as beach revetments artificially hardened with concrete, etc. It is used to promote. As a result, the seaweed settlement platform for algal reefs of the present invention contributes to ecosystem regeneration, such as the recent increase in natural harmony and the provision of a place for carbon dioxide absorption in the sea area.

A fixing base can be used. Further, when considering the construction of fish reefs and the like, it is possible to improve the adhesion of seaweeds by utilizing the seaweed anchoring base for alga reefs of the present invention on the surface of these fish reefs. That is, the seaweed settlement base for algal reefs of the present invention can be used for improving the surface characteristics of fish reefs and creating seaweed reefs, and can be installed on existing concrete surfaces or artificially created in sand mud areas. -By using it on fish reefs, seaweed spores can be attached and grown effectively.

  Furthermore, since the seaweed colony base for algal reef of the present invention does not change physical properties once installed, it is most suitable for public use.

  As a seaweed colonization base for algal reefs, it is desirable to design the pore diameter, porosity, shape, etc. in consideration of the difference in spore size and ecology depending on the seaweed. In addition, it is desirable to design the void diameter, porosity, shape, etc. of the seaweed settlement base for algae reef in consideration of the effects of pests on each sea area where the seaweed settlement base for algae reef is installed.
