As described above, according to the method of manufacturing the porous ceramic pellets of the present invention, artificial reefs for improving various eco-friendly water quality pellets made by processing waste glass to be processed into powder below a certain level and mixed with additives containing ocher powder In addition to reducing the environmental pollution caused by the waste glass by being used as a material for the production and replacement soil, there is an effect that can replace the existing artificial reef blocks and soil that had the potential for environmental problems.
In addition, according to the block using the pellet of the present invention, by using a new type of environmentally friendly porous ceramic pellets, there is an effect that can be used as artificial reefs for maintaining the vegetation of the flora and fauna underwater.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 (A) to (D) is an explanatory diagram showing a state in which the porous ceramic pellets of the present invention are molded into various sizes and shapes, and FIG. 2 is a block diagram showing a manufacturing process of the porous ceramic pellets of the present invention. 3A to 3N show an example of a block using the porous ceramic pellets of the present invention. Finally, the porous ceramic pellets produced are approximately spherical in shape as shown in FIG. 1 and have sizes in the range of 2 to 50 mm. In the following description, the name of the porous ceramic pellet may be used as a name abbreviated as pellet.
The main raw material used in the production of multi-use eco-friendly porous ceramic pellets is waste glass which is disposed of from buildings, automobiles and packaging containers. Waste glass collected for use in the production of multi-use eco-friendly porous ceramic pellets is first made into a powder through a predetermined shredding process using a shredder after a foreign material separation process and a washing process for removing foreign substances. The pulverized waste glass is pulverized in a pulverizer so as to be a powder having a particle size of 200 mesh or less which is a state suitable for carrying out the present invention in the raw material preparation step.
In the raw material preparation step, the crushing is performed in a crusher such that the loess powder, which is another raw material of the pellet, may have a particle size of 200 mesh or less. For reference, in the process of adjusting the particle size of the powder may pass through the screen having the particle size.

In the firing step, the strength and the porous size are determined according to the set temperature.
In addition, in the demolding step (S7) to remove the ocher by separating the pellet from the ocher sprinkled with a release agent to the pellet during molding.
Thus prepared pellets can be made of various types of pellets, as shown in (A) to (D) of Figure 1, because these pellets are made of a number of porous has an excellent effect on water purification or water quality improvement.
Meanwhile, 1.0 to 2.4 parts by weight of calcium carbonate may be further weighed in the raw material preparation step and mixed in the mixing step.
When the calcium carbonate is not included at all when mixing the raw materials, it is used for artificial reef or water purification and improvement, and when calcium deoxidation is included in 1 parts by weight, it is used as an alternative soil, and it is contained in 2.4 parts by weight. In this case, it is used for planting.
The method for producing the pellets described above is just one embodiment for producing a multi-use eco-friendly porous ceramic pellets according to the present invention, the porous ceramic pellets according to the present invention is more applied based on the method as described above It may be prepared by other methods.
On the other hand, the method of manufacturing a porous ceramic pellet block of the present invention, in the manufacturing method of the pellet, the forming step (S9) to put the pellets undergoing the drying step in the mold of the desired shape during the molding step and the forming step It comprises a firing step (S6) for heating the pellet product while setting the heating time and temperature according to the size, strength and shape gradually increasing the temperature, and the demolding step (S10) for separating the pellet block subjected to the firing step from the molding die do.
Therefore, various pellet blocks are made into various shapes as shown in FIGS. 3A to 3N by molding molds having various shapes of porous ceramic pellets.
The porous ceramic pellet block produced as described above has the following advantages. 1) It is possible to function as a porous artificial reef in coastal waters necessary for habitat, such as feeding, spawning, and growing of various aquatic organisms. 2) It is possible to maintain the fishery function continuously by constructing the marine forests using artificially generated algae blocks or by periodically providing new surface substrates that were not possible in the existing integrated artificial reef structure. 3) In coastal waters where algae are lost due to the tidal currents and strong external force, it has a functional effect as a fishing term for early marine forest formation. 4) The blast furnace slag, which is a conventional porous concrete or industrial waste, has a high possibility of secondary pollution, whereas the porous ceramic pellet block according to the present invention has the value of eco-friendly composition to improve marine pollution by using environmentally friendly and harmless waste resources. . 5) The application of this porous ceramic pellet block can be expected to raise the standard of living by rethinking competitiveness using fishery marine resources and improving the income of fishermen.
An embodiment of the present invention described above and illustrated in the drawings should not be construed as limiting the technical idea of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms. Therefore, such improvements and modifications will fall within the protection scope of the present invention, as will be apparent to those skilled in the art.
1 (A) to (D) are explanatory views showing a state in which the porous ceramic pellets of the present invention are molded into various sizes and shapes,
2 is a block diagram showing a process for producing the porous ceramic pellets of the present invention;
3A to 3N show an example of a block using the porous ceramic pellets of the present invention.
