Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to an apparatus for neutralizing or making alkaline water, such as drinking water or industrial water, which has become acidic. [Prior Art] Conventionally, methods of neutralizing oxidized water with lime-based calcium hydroxide or adding alkaline components such as sodium hydroxide have been considered to neutralize acidic contaminated water. Considering safety, there was no suitable method for neutralizing or slightly alkalizing drinking water. Therefore, a method has been considered in which the crushed corals and shells produced by the accumulation of calcareous skeletons of coral worm colonies are brought into contact with drinking water to neutralize it, but this method also lacks sustainability and neutralizes it. The drawback was that the efficacy of the drug did not last long. These ingredients usually only last about a month,
This was a major practical drawback. [Problems to be Solved by the Present Invention] An object of the present invention is to provide a neutralization device that is safe for neutralizing or slightly alkalizing drinking water and has a long-lasting effect. [Means for Solving the Problems] In order to achieve the above object, the present invention mixes and molds fine grains of animal shells, mineral stone soil, and a firing hardening agent, and bakes the mixture to form a porous material. The acid hydration device is constructed of a sintered material. The present invention consists of a sintered body, and the sintered body uses fine grains of animal shellfish as one of its raw materials. Examples of such fine grains of animal shells include coral grains or granules, shell powders, and the like. Furthermore, mineral stone soil is used as a raw material. As the mineral stone soil, any of the clays normally used in the production of ceramics and fine ceramics can be used, such as white silica stone, kaolin, kibushi clay, pottery stone, bentonite, feldspar, dolomite, talc, etc. be able to. Furthermore, a baking hardening agent is also used. As such baking hardening agents, alkali metal silicate adhesives, silica sol adhesives, phosphate adhesives, organic adhesives such as starch, etc. can be used, but if drinking water It is preferable to use a material that is safe even if it oozes out. These animal shells, mineral stone soil, and calcined hardening agent are mixed in appropriate amounts. Examples of mixing include animal shells: 30% to 90% (wt%, the same applies hereinafter);
Preferably 50% to 70%, mineral stone soil: balance, firing hardening agent: mixed slightly as appropriate. The mixture is formed into a desired shape such as a disk, cylinder, or cube and fired. At this time, the molded product may be formed into a donut-like disk shape, as shown in FIG. 1, and a large number of small holes 1 may be formed therethrough from the upper end to the lower end. Firing is carried out at a desired temperature, but generally speaking, firing at a higher temperature tends to make the water to be treated more alkaline.
Normal firing temperature is 600℃~1000℃, preferably 700℃
Performed at ~800°C. When fired in this manner, the sintered body becomes porous, allowing water to penetrate into the inside of the sintered body. Such a sintered body is the main material in the present invention. [Function] When the acidic water hydrating device of the present invention is immersed in drinking water,
The hydrogen ion concentration (PH) of drinking water shifts to the neutral or alkaline side. Not only drinking water but also industrial water, industrial water, irrigation water, etc., similarly shifts from acidic to neutral or alkaline. [Example] Example 1 150 g of crushed reef-building coral (approximately 1 mm sand-like),
150g of clay clay, lead-free frit as firing hardening agent
60g of the mixture was mixed and formed into a disk shape with a diameter of 9.5cm and a thickness of 2.5cm, and fired at 750°C to form a ceramic to obtain a porous sintered body. Add this to 1 part tap water with a pH of 6.8.
When I poured it into the water and took it out after 10 seconds, the pH of the tap water was 7.4. Example 2 The acid hydrator made of the sintered body produced in Example 1 was placed on a tap, water was sprayed at a rate of about 3:00 for 1 minute, and the hydrogen ion concentration of the water was measured.
It was 7.4. In Examples 1 and 2, a pH measuring reagent BTB (bromothymol blue solution) was used to measure the hydrogen ion concentration. Example 3 The acid hydration device made of the sintered body produced in Example 1 was analyzed by Mr. Kazuo Sakano, the chief measurer, at the Clinical Laboratory Department of the 31 General Health Center, 1158 Sakaimatsu, Ota-cho, Minokamo City, Gifu Prefecture. . The results were as follows. (Test method) Immerse the acidic water hydrator in tap water 1 of PH6.1,
The mixture was stirred lightly at first, and the pH and temperature were measured over time. (Results) The results are as shown in Table 1.

[Table] [Effects of the Invention] When the acidic water hydrator of the present invention is immersed in water, the water is quickly made alkaline or neutralized. Moreover, this effect lasts for at least 3 months. If a sintered body whose neutralizing ability has diminished after more than three months has passed, its potency will be restored by drying it and exposing it to a city gas flame. In addition, minerals flow out into the water, making it possible to easily produce mineral water.
