Description

Seaweed culture substrate with micropores

The invention relates to a seaweed culture substrate, especially a seaweed culture substrate with micropores.

As a transparent plastic material, glass has been often made into windows since ancient times to provide excellent lighting functions in buildings. In addition to its transparency, glass also has a natural luster in appearance. Therefore, a large number of glass containers are launched on the market and are widely loved by people. However, the glass material has a non-crystalline structure with hard and brittle mechanical properties. It is easy to be scrapped due to collision and fracture during use, and its fragments are hard and sharp and easily hurt people. More and more glass products are used and produce a lot of waste. When the general garbage enters the garbage incinerator, the molten glass will stick to the inside of the furnace body and shorten the service life of the garbage incinerator, thus causing difficulties in disposal.

At present, the recycling rate of scrap glass is not high. The main method of scrap glass is to form waste glass sand by breaking and crushing and removing acute angles after processing. At present, it is mostly used in asphalt paving, ceramic raw materials/glaze, and light weight. Although aggregates/foamed glass, glass art products and bright colored glaze are widely used, the amount of scrap glass produced is increasing year by year and the amount is much larger than the amount of removal of the above-mentioned applications. Therefore, the market has always needed to continue to develop and update Many different applications balance the output and removal of waste glass in order to avoid the disposal of waste glass and cause the aforementioned environmental pollution and biosphere hazards.

On the other hand, collecting wild seaweed at the seaside as ingredients for personal use or sale, Ancient is one of the economic activities of various maritime countries. With the development of science and technology, the production of seaweed has also progressed from wild collection to artificial cultivation to supply market demand in larger quantities. Moreover, since the cultivation of seaweed is mostly carried out in the coastal waters, no fertilization and irrigation are required. It can be produced without occupying land on the arable land, so its cost is low and it has high economic value. The conventional seaweed culture, such as the rope vertical culture method shown in Fig. 7, is that hollow plastic tubes 90 are interlaced to form a net-shaped buoyancy scaffold 9 and multiple thick twisted ropes 92 are tied to the plastic tube 90 as a supply of seaweed 94 In order to prevent the thick twisted rope 92 from being entangled with each other under the reciprocating push of the waves and affecting the illumination of the seaweed, a vertical block 96 such as a rock is tied to the end of the thick twisted rope 92 to maintain the thick twisted rope. 92 is roughly vertical in sea water.

However, because seaweed farming sites usually choose locations with long annual sunshine hours to facilitate the growth of seaweeds for photosynthesis, long-term soaking of thick ropes in seawater is inherently vulnerable to saline erosion, plus strong ultraviolet and infrared exposure in the sun. As a result, the thick twisted rope is often damaged and decayed, causing the thick twisted rope used as the base material for seaweed culture to fall off and lose production capacity. Moreover, thick twisted ropes can only be tied to the scaffolding, and thick twisted ropes cannot be set in the vast hollow area 98 of the hollow plastic tube 90 of the scaffolding, so that the output per unit area has not been high.

Therefore, how to apply waste glass to seaweed cultivation, on the one hand to achieve waste recycling, on the other hand to improve the efficiency of cultivating seaweed, and to overcome the above-mentioned shortcomings, is the problem to be solved by the present invention.

In view of the above problems, the main purpose of the present invention is to provide a microporous seaweed culture substrate made of recycled waste glass, which can remove a large amount of waste glass and conform to the trend of environmental protection.

Another object of the present invention is to provide a seaweed culture substrate with micropores, Through the low-temperature sintering method, the glass substrates are combined with each other without being completely dissolved, and a seaweed culture substrate with three-dimensional holes is formed, so that the seaweed sporophyte can enter and grow firmly, effectively using the good corrosion resistance of the glass material It can solve the production loss caused by the damage and decay of the thick noose culture.

Another object of the present invention is to provide a seaweed culture substrate with micropores. By suspending the seaweed culture substrate, which is close to the seawater, such as specific gravity, it can greatly increase the amount of seaweed culture per unit area, so that the output is increased and the production is increased. Capacity.

To achieve the above objective, the present invention provides a seaweed culture substrate with micropores for seaweed culture. The seaweed culture substrate includes: a glass sintered buoyancy module with at least one completely enclosed cavity formed inside; and a buoyancy module connected to the above The culture block of the buoyancy module is formed with a plurality of three-dimensional holes larger in size than the sporophyte of the seaweed, for the sporophyte of the seaweed to enter, and the culture block is formed by combining a plurality of glass substrates, and the glass substrates are mutually formed. The combined part will randomly form a plurality of culvert micropores with pore diameters smaller than the above-mentioned three-dimensional pores. The aforementioned culvert micropores are structured so that seawater can be distributed to the above-mentioned aquaculture block by capillary phenomenon, and the size of the above-mentioned culvert micropores It is smaller than the sporophyte of the aforementioned seaweed, and the cavity of the aforementioned buoyancy module makes the specific gravity of the seaweed culture substrate approach seawater.

In an embodiment of the present invention, the module body is made of the above-mentioned glass base material by low-temperature sintering of silica sand, and the above-mentioned glass base materials are integrally formed by combining with each other.

Compared with the conventional technology, the microporous seaweed culture substrate disclosed in the present invention almost completely uses recycled waste glass and uses a large amount of waste glass, which can greatly digest glass waste and is environmentally friendly. As for the manufacturing process, it is completely environmentally friendly. I don’t care about the elimination of bubbles inside the glass. Instead, it is necessary to pour air into the buoyancy module to form a large number of bubbles, which makes the process very simple and the yield rate is extremely high; the rest of the cultivation area is also made of waste glass, but only needs to be micronized Rear Low-temperature sintering only needs to apply low-temperature kiln firing at 300 degrees Celsius to soften the surface of the granular glass substrate to be able to adhere to each other without a lot of high-temperature processing, so both the manufacturing yield and output efficiency are very good. In addition, a plurality of three-dimensional holes are formed in the cultivation area to allow the sporophytes of the seaweed to enter. The seaweed can penetrate deep into the cultivation area and when it grows outwards, the whole seaweed can be fixed on the seaweed cultivation substrate because the glass has good weather resistance. Because it is not easy to decay and damage, the cultured seaweed is not easy to lose, and the culture area is maximized by the plate or spherical seaweed culture base material, which effectively increases the output per unit area.

The following specific examples illustrate the implementation of the present invention. Those familiar with the art can easily understand the advantages and effects of the present invention from the contents disclosed in this specification.

The structure, ratio, size, etc. shown in the drawings in this specification are only used to match the disclosure content of the specification for the understanding and reading of those who are familiar with the art, and are not used to limit the implementation of the present invention. Any structural modification, size adjustment, or change in the proportional relationship, without substantial changes to the technical content, shall also be regarded as the scope of the implementation of the present invention.

The glass particles used in the present invention are the first to recycle the discarded glass products, and the process of destroying, crushing and removing the acute angles to produce glass particles with a size ranging from 0.2 cm to 0.6 cm, which is referred to herein as a glass substrate. The first preferred embodiment of the present invention is shown in Fig. 1. An example of a seaweed culture substrate with micropores is illustrated as a plate-like structure with a length of 100 cm, a width of 50 cm, and a height of 2 cm, which mainly includes a buoyancy module 2 and a culture block 3. , The buoyancy module 2 of this embodiment puts the above-mentioned granular glass substrate into a mold (not shown), sinters and melts at a high temperature of 750°C, and foams it from the inner edges of the four sides of the buoyancy module 2. At the same time, a connecting portion 26 is formed on each side. In this example, it is explained as a perforation. The inside of the buoyancy module 2 is foamed to form a plurality of closed cavities 21 with a diameter of about 1-10 mm. The closed cavities 21 are roughly evenly distributed in the buoyancy. The interior of the module 2 makes the overall specific gravity of the buoyancy module 2 smaller than that of seawater and can float in the seawater. In this processing process, compared with general glass processing that needs to remove air bubbles in order to maintain the clearness and transparency of the glass, the present invention does not have this concern at all, and it also makes the processing cost very low, the output efficiency and the product yield are quite good. There is no elimination problem.

The buoyancy module 2 has an upper surface 22 and a back surface 24 opposite to the upper surface 22. In this embodiment, the back surface 24 of the buoyancy module 2 is placed at the bottom of another mold, and the glass substrate 34 is randomly scattered in the mold. The cloth is stacked on the back 24. The above-mentioned mold is provided with bumps that communicate with and penetrate the connecting portion 26 so that the connecting portion 26 can extend from the buoyancy module to the breeding area, and then pass through 300 It softens at a low temperature, so that the surface of the glass substrate 34 gradually softens and slightly melts. Therefore, the abutting part adheres and welds to each other. Randomly, a breeding area 3 is formed on the back 24 of the buoyancy module 2, because the spilled glass substrate is deliberately There are large and small, so a large-sized three-dimensional hole 32 and a small-sized culvert micropore 36 will be formed in the cultivation block 3. If observed under a microscope, it can be found that a large number of glass substrates 34 include at least one low-temperature surface fusion zone 342 which is mutually fused with the adjacent glass substrate 34, and a core non-fusion zone 344 located inside. Due to the temperature of the processing environment Demand is significantly reduced, making product manufacturing less difficult, and output efficiency and product yield are also very good.

Furthermore, because the buoyancy module 2 is also made of glass material and has good mutual melting with the glass substrate 34, the glass substrate 34 will also interact with the back 24 of the buoyancy module 2 during the above-mentioned low-temperature surface adhesion process. They are welded to each other to form a low-temperature surface welding area 342, whereby the cultivation block 3 is fixed on the buoyancy module 2, and this temperature environment will not cause any interference to the sintered structure of the buoyancy module 2.

The culture block 3 has a connecting surface 31 connected to the buoyancy module 2 and a culture surface 33 for cultivating seaweed. Since the above-mentioned three-dimensional hole 32 refers to a perforation with a size greater than 0.4 mm, it is compared with the sporophyte 4 of general seaweeds. The size of the seaweed is 400μm, which can allow the sporophyte 4 of seaweed to enter smoothly. After a period of growth, the seaweed gradually grows out of branch leaves, and the seaweed holder can be smoothly fixed in the three-dimensional hole. There is no traditional hollow plastic tube or thick The aging or decay of the twisted rope makes the seaweed be firmly fixed.

Because the area where seaweed grows, small fish are usually attracted to inhabit, and fish excrement is accompanied by it. The ammonia in it will also be harmful to seaweed. The large amount of water culvert micropores 36 are less than 400μm in size, which is allowable. The seawater infiltrates through the capillary phenomenon and greatly slows down the flow rate of the seawater, so that nitrifying bacteria can stay in this area as the seawater is slowed down, assisting Treatment of ammonia produced by fish inhabitation, whether it is nitrate bacteria or nitrite bacteria, can forage and grow and multiply, and maintain the health of the seaweed growth environment and promote the growth of seaweed.

Because each seaweed culture substrate 1 of this embodiment has four connecting parts 26 for multiple series and parallel applications to expand the cultivation area and increase production, as shown in Figure 2, this embodiment uses a stainless steel wire with a diameter of 4 cm. 5 Pass through each connection part 26 and set three seaweed culture substrates 1 in series within a range of 1 meter close to the sea surface water depth. In response to the increasing weight of seaweeds, styrofoam floats are added to the four corners. 6 to support the seaweed culture base material 1 not sinking. Because the seaweed culture base material 1 disclosed in the present invention has good light permeability, the seaweed can grow on the culture surface of the culture block toward the depth of the sea, and will not be affected by the seaweed culture base. The material 1 itself shields the sunlight required for growth.

The seaweed culture substrate 1 of this embodiment completely uses scrap glass, which can accelerate the speed of removing the waste glass; in addition, because the seaweed culture substrate is made of glass material, it has good weather resistance and is not easy to damage even if it is used for a long time. Smoothly solve the problem of the loss of the cultured seaweed due to the decay and damage of the base material and the reduction of the output; especially the three-dimensional holes can allow the seaweed to grow firmly, and the culvert micropores can avoid the erosion of the ocean current, ensuring that the seaweed and nitrifying bacteria grow in a slow flow, Ensure that the seaweed growth environment will not be degraded by the habitat of fish, and create a good compound growth environment.

', the inside of the buoyancy module 2'also uniformly forms a closed cavity 21' with a diameter of about 1-10 mm, so that the overall specific gravity of the buoyancy module 2'is smaller than that of seawater. Please refer to Figure 4, followed by a larger ball A certain number of glass substrates 34' are laid on the bottom of the shaped mold (not shown) and then placed in the buoyancy module 2'. Then, more glass substrates 34' are filled in the mold and softened at low temperature, so that the inside of the glass substrate remains Keep the original condition, but the surfaces stick to each other as well as the buoyancy module 2', so the outer surface of the buoyancy module 2'is covered to form a large spherical culture block 3'to complete the spherical seaweed culture substrate 1' . Please refer to Figure 5. The application of the seaweed culture substrate 1'in the seaweed culture of this example is to connect a plurality of seaweed culture substrates 1'with a stainless steel chain 7'and a counterweight 8', such as a cement block, respectively. The seaweed culture substrate 1'is maintained at a depth within 1 meter below the sea level on the seabed. The spherical shape of the seaweed culture substrate 1'of this example has the largest surface area, and because it is made of transparent glass material, it has good light transmittance. Driven by the random flow of the waves, the seaweed on the entire surface of the cultivation area 3'can be well illuminated, so the cultivation volume and output per unit cultivation area can be further maximized.

Please refer to FIG. 6 for the third preferred embodiment of the present invention. In this example, the same parts as the previous preferred embodiment will not be repeated here. Similar components also use similar names and labels, and only the differences are described.
