Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purification agent capable of imparting a deodorizing effect and an antibacterial effect to water and adding a mineral component to water, and a method for producing the water purification agent.

[0002]

2. Description of the Related Art Tap water contains chlorine and calcium in order to prevent the generation of bacteria and the like, and the content ratio of chlorine and calcium differs depending on each region. In some areas,
When tap water is used for drinking or for food, there is a drawback that chlorine or odor of chlorine is applied to the nose. For this reason, ordinary households and restaurants have conventionally purified tap water using a purifier and used the purified water for eating and drinking. Conventionally, activated water has been generally stored in a water purifier, and the activated carbon absorbs and removes chlorine and calcium contained in tap water to convert tap water into water suitable for food and drink.

[0003]

The conventionally known activated carbon used in the water purifier is required to make the activated carbon function efficiently.
The size was made granular or pebble-sized to increase the surface area in contact with water. However, since the size of the activated carbon is small, dust and water scale contained in tap water easily adhere between the activated carbons, and clogging has occurred after use for about several months. Due to the clogging of the activated carbon, germs and odors are generated in the purified water, the flow rate of the water passing through the purifier is significantly reduced compared to the supply flow rate of tap water, and the effect of removing chlorine and calcium is reduced. There were drawbacks. As described above, in the conventional activated carbon, the effective use period is as short as several months, so that the activated carbon has to be replaced several times a year, which has a disadvantage that it is complicated and costly.

[0004] In addition, since conventional activated carbon has a granular or pebble size, the activated carbon is put into a special bag or container,
The bags and containers were placed in the housing of the water purifier. For this reason, there was a drawback that the housing itself of the water purifier was large enough to accommodate bags and containers dedicated to activated carbon.

Further, in a conventional water purifier using activated carbon, water after removing chlorine and calcium with activated carbon loses its antibacterial action. Therefore, in order to obtain water having an antibacterial effect, the water must be passed through a device that imparts an antibacterial effect to the water. In this case, there is a problem in that the device becomes large-scale and costs increase.

The present invention has been made in view of the above points, and provides a water purifying agent which deodorizes chlorine and chalky, adds a mineral component to water, has an antibacterial action in water, and has a long replacement period. It is intended to do so.

[0007] The present invention further provides a method for hardly producing a water purifying agent having deodorization, addition of mineral components, and antibacterial action.

[0008]

According to the present invention, there is provided a water purification agent comprising at least one of activated carbon, porcelain clay, dolomite, tourmaline, maltstone, Iio stone, and silicate earth. And silver and / or titanium, and the mixture is heated to be solidified.

In order to achieve the above object, a method for producing a water purification agent according to the present invention is characterized in that activated carbon, porcelain clay, dolomite, tourmaline, maltite, iodolite and silicate earth, and silver And / or titanium and the resulting mixture is anoxic in a state of 1100-1250 degrees Celsius.
It is designed to be heated between degrees.

[0010]

Next, the present invention will be described. The water purifier according to the present invention comprises: activated carbon having a weight ratio of 20 to 50%;
30 to 60% by weight of porcelain clay; 15 to 45% by weight of dolomite, tourmaline, maltite, Ioite and silicate earth; silver of 0.05% or more by weight; And / or titanium at a weight ratio of 0.1% or more. All values up to the numerical values of the above materials are included in the range.

The activated carbon has a function of removing odors such as chlorine and chalky, and it is desirable to use coconut palm activated carbon. Dolomite, tourmaline, barley stone, Ioite and silicate earth are for adding mineral components to water. Porcelain clay has a function of bonding activated carbon and dolomite when mixed, and it is desirable to use weathered clay of granite. Silver and titanium are used to impart antibacterial action to water.

Activated carbon having a weight ratio of 20 to 50% and a weight ratio of 3
0-60% porcelain clay, 15-45% by weight of dolomite, tourmaline, maltstone, Ioite and silicate earth, and silver and / or 0.05% by weight or more Titanium having a weight ratio of 0.1% or more is put into a vacuum kneader, and they are mixed in a vacuum state. Mixing in a vacuum kneader is to make the mixed product as air-free as possible.

The mixture mixed in the vacuum kneader is formed into a single solid 10 having a predetermined shape as shown in FIG. 1, for example. The solid 10 shown in FIG. 1 has a dome shape.
The dome-shaped solid 10 has a large number of through-holes 12 formed near the periphery, but does not have the dome-shaped apex portion and the vicinity of the apex portion. For example, when used in a household water purifier, the diameter of the dome-shaped solid 10 is 4 to 8 cm and the inner diameter of the through hole 12 is about 1 to 2 mm, but depending on the size of the water purifier. The diameter of the solid material 10 and the inner diameter of the through hole 12 are not limited to these values. In addition, the shape of the solid material 10 is not limited to the dome shape, and is not limited to the shape forming the through hole 12.

The molded solid 10 shown in FIG. 1 is placed in an oxygen-free sintering furnace or the like, and is heated from 1100 ° C. to 1250 ° C.
Bake for 12 hours from time. Oxygen-free sintering furnace is patent 2
No. 038214, in which a solid object 10 to be heated is heated in a closed crucible made of a material having a high thermal conductivity generating far-infrared rays in an oxygen-free state. . The sealed oxygen-free state is achieved by, for example, a vacuum state.

When the solid material 10 is heated in a conventional aerobic incinerator, the temperature does not reach a high temperature of 1100 ° C. to 1250 ° C., and smoke, gas and odor are generated.
When the solid material 10 is heated in an oxygen-free baking furnace,
It reaches a high temperature of 100 to 1250 degrees Celsius, and solid matter 10
There is no smoke or bad smell caused by the combustion of the oil. By heating the solid matter 10 at a high temperature of 1100 ° C. to 1250 ° C. for a predetermined time in an oxygen-free baking furnace, a hardened and solidified water purification agent 14 is completed.

The firing temperature ranges from 1100 degrees Celsius to 125 degrees Celsius.
0 degrees is desirable. If the temperature is lower than 1100 degrees Celsius, the product (water purification agent 14) may not be baked. If the temperature exceeds 1250 degrees Celsius, the product hardens to a metal-like state, so that the mineral components are not eluted and the product is unusable. Note that the firing temperature is optimally from 1150 degrees Celsius to 1220 degrees Celsius. The firing time is desirably from 8 hours to 12 hours. If the time is less than 8 hours, the firing condition may be uneven. If the time exceeds 12 hours, fuel cost may be required and the product may be overburned. The firing time is optimally between 9 hours and 11 hours.

The weight ratio of activated carbon is set to 20 to 50%.
This is because if it is less than 20%, the activity of activated carbon is reduced, and if it is more than 50%, the proportion of the porcelain becomes small and it does not solidify well during molding. Activated carbon has an optimum weight ratio of 30 to 40%. In this range, the activated carbon has a high activity capacity and solidifies well at the time of molding. The weight ratio of the clay was 30-60%. This is 30
If it is less than 60%, it does not solidify well during molding, and the product after sintering is brittle and easily cracked and cannot be used as a solid product. If it exceeds 60%, the proportion of activated carbon is reduced, This is because the activity of activated carbon is reduced. It is to be noted that the optimum weight ratio of the pottery clay is 40 to 50%.

The weight ratio of 15 to 45% of dolomite, tourmaline, barley stone, Ioite and silicate earth is 15 to 45%. If the content is at least one of dolomite, tourmaline, barley stone, Ioite, and silicate earth, the mineral content may not be sufficient if the content is less than 15%. Ratio becomes too large, and the function of other materials deteriorates.

Silver and titanium are used for imparting antibacterial activity to purified water. However, with silver having a weight ratio of less than 0.5% and titanium having a weight ratio of less than 0.1%, an antibacterial effect is obtained if the amount is too small. Few. Conversely, adding a large amount of silver or titanium is only costly. Therefore, the weight ratio is 0.05 to
If 0.1% silver and / or titanium has a weight ratio of 0.1 to 0.5%, it has an antibacterial effect and is economical.

The water purification agent 14 manufactured as described above is one large lump and has a large number of through holes 12. In other words, the water purification agent 14 is stored in the water purifier as it is, and is not a granular or pebble-like material that can be put in a bag or a container as in the related art.

Here, an example of purifying water using the water purifier 14 of the present invention will be described with reference to FIG. Water purifier 16
Is a lower housing 20 forming a wide space 18 therein.
And an upper housing 22 and a lower housing 20
Opening and closing the boundary between the upper housing 22 and the water purifier 14 into and out of the space 18. A guide 24 for holding the water purification agent 14 is formed in the lower housing 20, and the water purification agent 14 is placed on the guide 24.

The upper housing 22 is for connecting a water faucet 26 and the like. A first venturi portion 28 is formed in the upper housing 22 on the side of the water faucet 26, and a second venturi portion is provided at a position communicating with the wide space 18. Form 30. At the position of the second venturi section 30, an air introduction hole 32 communicating between inside and outside is formed.

The tap water introduced from the tap faucet 18 is
The first venturi 28 enters the space 18 and the first venturi 28 increases the flow rate of water.
Thereafter, air is introduced from the outside to the position of the second venturi section 30 through the air introduction hole 32, and the air is mixed with the water at that position. By mixing water and air, the flow rate of the mixture of water and air is further increased, and the mixture of water and air collides with the dome-shaped water purification agent 14 at the increased flow rate. By causing the mixture of water and air to collide with the water purification agent 14 at a high speed, separation of activated carbon from water, such as chlorine and calcium, contained in tap water can be performed as compared with the conventional method in which water simply passes through. Promoted.

By vigorously colliding the mixture of water and air with the water purification agent 14 at a high speed, the mixture of at least one of dolomite, tourmaline, malite, Iioishi and silicate earth, which are the components of the water purification agent 14, is obtained. Water comes into contact with the material. As a result, the dissolution of the mineral component in water is promoted, and the water that collides with the water purification agent 14 becomes water having a mineral component, which is more suitable as drinking water. Further, since water comes into contact with silver or titanium, which is a constituent material of the water purification agent 14, the water colliding with the water purification agent 14 has an antibacterial action.

The water that has collided with the water purification agent 14 rebounds into the large space 18 and is then discharged to the outside through the through hole 12. By forming the water purification agent 14 in a dome shape, the number of the through holes 12 can be increased as compared with a planar shape, the flow amount to be purified can be made closer to the flow amount to be supplied, and the flow amount is reduced by passing the water purification agent 14. Can be prevented. Further, the water that has collided with the dome-shaped water purification agent 14 is exposed to the surface of the dome-shaped water purification agent 14 and the many dome-shaped through holes 1.
2, iron rust and trihalomethane contained in chlorine, chlorine and tap water are adsorbed on activated carbon as a constituent material of the water purification agent 14 at that time.

By forming the water purification agent 14, which is one solidified product, into a dome shape, the strength of the water purification agent 14 is increased, and the water purification agent 14 can withstand the strength even if the water collides with the top portion at a high flow rate. be able to. Further, by forming the water purification agent 14 in a dome shape, the weight of the water purification agent 14 can be reduced.

Since the water purifying agent 14 is composed of one solid, it does not require a bag or a container for accommodating activated carbon as in the prior art. For this reason, the size of the housing of the water purifier can be made smaller than before.

[0028]

As described above, according to the water purification agent according to the present invention, one having activated carbon, porcelain clay and mineral components,
It is made by mixing silver and / or titanium and firing to form one hard lump. By bringing this into contact with water, activated carbon can be used to deodorize chlorine and chalky, and mineral components can be added to purified water by dolomite and the like, and antibacterial action of purified water by silver and titanium. Can be given. Further, since the water purification agent can be formed into one hard lump, a bag or a container for storing activated carbon as in the related art can be dispensed with, and the housing of the water purifier can be made smaller than in the related art. As the hardness of the water purifier is high, it is possible for the water purifier to collide with water at a high speed, making it difficult for the water purifier to adhere to dirt and water scale, and the effective use period of the water purifier is significantly higher than that of conventional activated carbon. It can be longer. High-speed collision of water with the water purifier can promote the separation of chlorine and calcium, and can promote the elution of mineral components. Further, by forming the water purification agent into a single dome shape, it is possible to prevent a reduction in the amount of purified water as compared with conventional activated carbon in which small particles are stacked. Furthermore, by making the activated carbon into a dome shape, the weight of the activated carbon can be reduced as compared with a conventional activated carbon laminate.

According to the method for producing a water purifier according to the present invention, a water purifier having a high hardness can be produced by firing at a predetermined temperature in an oxygen-free state. In addition, when the constituent materials are mixed in a vacuum state, air can be evacuated from the inside of the mixture, and the hardness of the water purification agent as a product can be further increased.
