Description

  The present invention relates to a method for producing artificial ore.

  As the public's needs for hot spring recreation increase, hot spring travel is gradually becoming one of the most preferred leisure activities of the public. In the market, bathing agents with the names of many famous hot springs have appeared, so consumers can enjoy hot springs easily at home without having to go to hot springs crowded with many tourists. Can be done. Furthermore, artificial hot spring devices have been designed, and consumers can enjoy various hot springs according to their needs.

  The hot spring powder contained in the bathing agent or the hot spring grains contained in the artificial hot spring equipment must all take into account the elution efficiency of ions, and the design of the high and low elution efficiency is related to the demand of users. It has become a thing. As an example, the hot spring powder used for the bathing agent that is discarded after use is considered to be better as its elution efficiency is higher in consideration of disposable characteristics. On the other hand, hot spring grains used in artificial hot spring equipment have a relatively large impact on cost, so it is necessary to consider the elution of an appropriate amount of ions at the same time, and the long-term effect is also an essential condition. .

  The invention about the elution efficiency increase of the hot spring grain or artificial ore is disclosed in Japanese Unexamined Patent Application Publication No. 2003-267859. The hot spring grains in the present invention are tourmaline, obsidian, zeolite, porcelain clay and ALC (autoclaved-light-concrete) as main raw materials. The main production process is to first raise the temperature from 200 ° C to 400 ° C and heat for 5 hours Further, the temperature is raised from 400 ° C. to 700 ° C. and heated for 3 and a half hours, and then this is maintained for 5 hours. The point is to increase the porosity of the hot spring grains that are the material, and when the bubbles are 50% or more, the contact area with water increases, which helps to increase the elution effect.

  Japanese Patent Laid-Open No. 2001-322877 provides a solution on the manufacturing process for the problem of how to increase the duration of the effect of hot spring grains or artificial ore. Sinter at a temperature of 600 ° C. for 4 hours.

  In summary, in considering the elution effect of hot spring grains or artificial ore, the solution has been made solely by improving production conditions or materials. Therefore, in order to solve the problem that materials currently on the market do not have a good elution effect, if artificial ore or hot spring grains with a high elution rate are required, the method of improving the manufacturing process is adopted first. Should be considered. However, on the other hand, in order to further promote the popularization of hot spring leisure, it is also necessary to link the manufacturing process to economic benefits.

  Based on the problems described above, the present invention provides a method for producing artificial ore that uses a lower sintering temperature to form artificial ore and has a low production cost and good elution efficiency.

  In the method for producing artificial ore according to the present invention, natural ore is pulverized or ground into powder, and this powdered natural ore is granulated, and this is fixed at a certain temperature between 200 ° C. and 550 ° C. Heat on time. In this step, a suitable temperature is 300 ° C. and a suitable heating time is 3 hours.

  In the step after the granules are formed, these granules are heat-dried and heated from room temperature to a constant temperature.

  The above-mentioned natural ore can be lithium feldspar, tourmaline, barley stone, Sekiko hot spring powder (hot spring deposit in Taiwan's famous hot spring area called Sekiko), zeolite, or any combination thereof.

  The artificial ore provided by the method of the present invention is excellent in elution efficiency and can be produced at a low production temperature, and thus has an advantage of low production cost. For this reason, since it can reduce production cost by using for an artificial hot spring apparatus, it is useful for the spread of the said product, and also supplements the shortage of natural hot spring resources.

  The following is a detailed description of the detailed features and merits of the present invention in an implementation system, and the contents thereof can be understood by those who are familiar with the technology concerned, and can understand the technical contents of the present invention. Further, if the person can be implemented by this and is familiar with the related technology, the object and merit of the present invention can be easily obtained based on the contents published in this manual, the scope of patent application, and the drawings. Can be understood.

  FIG. 1 is a preferred embodiment showing a method for producing artificial ore according to the present invention in a flowchart.

  First, a certain type of natural ore is selected, and the natural ore is pulverized or ground into a powder form (step 101), thereby increasing the effective surface area of the ore material. Next, after adding an appropriate hardening | curing agent, a foaming agent, and water to this ore powder and making it granulate with a specialized machine, this granule is heat-dried (step 102). Next, heating is performed at a low temperature for a certain period of time (step 103), and the temperature is lowered to room temperature (step 104), thereby completing the production of the artificial ore of the present invention.

  The temperature and time used in the low-temperature heating process are determined by two major factors: porosity and maintenance of ore characteristics. The temperature range can be between 200 ° C. and 800 ° C. and the heating time can be between 2 hours and 3 hours, of which a suitable temperature is 300 ° C. The heating time is 3 hours.

  The ore may be any natural ore containing hot spring water and / or ions to be included in the mineral spring water, such as lithium feldspar, tourmaline, barley stone, Sekicho hot spring powder, zeolite or these. Can be selected from any combination.

  FIG. 2 shows an example of the preferred use after the completion of the artificial ore.

  In this embodiment, the use in an artificial hot spring apparatus is taken as an example, but in actual use, it can be used in a mineral water production apparatus, a drinking water apparatus, and the like.

  As shown in FIG. 2, the artificial hot spring device 1 is composed of an ore container 3 connected to a water draw pipe 5 and a water discharge pipe 7, and a heater 9 used for heating the ore container 3.

  Since the ore container 3 contains artificial ore or natural ore that supplies mineral substances or ions in the water, the artificial ore or natural ore contained in the container is ionized when the water flow passes through the ore container 3. Is eluted in water. Therefore, the water discharged through the water discharge pipe 7 becomes mineral water containing mineral substances or ions.

  Moreover, by heating the ore container 3 with the heater 9, a fixed temperature can be maintained, and heating is beneficial for improving the ion precipitation efficiency of the ore.

  The best embodiment of the present invention will be described below.

  Lithium feldspar is ground into a powder in a mortar, 10 ml of liquid glass and an appropriate amount (0 to 0.5 g) of sodium bicarbonate are added to 50 g of the ore powder, and 25 to 30 ml of water is added during the granulation process. Granules of about 1 cm are produced with a granulator.

  Subsequently, this is put in a low temperature drying furnace and dried by heating at 105 ° C. for 1 hour, and then heated by increasing the temperature from 30 ° C. to 300 ° C. in a higher temperature drying furnace (temperature rising time is 100 minutes) ) After sintering at 300 ° C. for 3 hours, the temperature is finally lowered to room temperature, thereby completing the production of the artificial ore.

  The finished product is put into an artificial hot spring device and subjected to a temperature effect test, a water circulation test, an elution amount test, an elution endurance test, an elution component adjustment test, and a filtration test.

  Alternatively, put the product directly into water, change the temperature and time parameters, conduct a dissolution test, and perform water quality analysis.

  Here, by measuring the conductivity, the elution efficiency can be used as a reference.

The data of dissolution test and water quality analysis for different samples are shown in the following table.

  From these data, it can be seen that the product produced by this production method had good elution efficiency under conditions of a water temperature of 45 ° C. and a test time of 1 hour.
