CONSTITUTION:The mixture of a soluble component 21 (example: mineral component) and an insoluble component 20 (example: polypropylene resin) is allowed to foam in order to form a granular or columnar substance having fine air holes 22. Thus, the water quality-adjusting material which adjusts effectively the concentration of eluted component to a certain range can be obtained without using a complicated mechanical or electrical means. Said material can also give the filler material for eluting a mineral component effective for a water purifier, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a water quality conditioning material, and particularly to a water quality conditioning material suitable for use in water purifiers that elutes mineral components.

[Background of the invention]

Conventionally, in order to contain a certain amount of the necessary ingredients in water, there were many methods such as injecting concentrated water while detecting and controlling the concentration using an injection bonder. It would be complicated, expensive, and expensive to easily elute mineral components using a simple method. Therefore, a material that is packed with a filler to be eluted and eluted by passing water has been supplied with a structure as described in JP-A-56-95392, but natural stones such as jinseeds cannot be eluted by light. It is sufficient that there are no pores and that the bath can be easily removed.

On the other hand, even if calcium hydroxide, which has a high specific yield mPs, is solidified and used as a mineral material, it will elute rapidly during retention without water flow, and the concentration will be too high.
The mineral material had become sticky, making it unsuitable for wheat. Therefore, it is necessary to provide a water RA adjusting material that can control the eluted components within a certain concentration range and is suitable for production.

[Purpose of the invention]

An object of the present invention is to provide a water quality 114II material suitable for controlling the amount of components exposed to the bath within a constant range.

[Summary of the invention]

The present invention provides a constant concentration elution material 4, such as a mineral elution material used in a water purifier, by mixing an OTm component and an insoluble component, foaming the mixture to form fine bubbles on the t, and solidifying the material. This makes it possible to control the amount of components to be eluted into water to a certain degree, which is an additional 4 points for water quality regulating materials.

[Practice of invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 2 is a sectional view of the water purification iW1 using an embodiment of the present invention, showing the faucet connection part 2, body 3, switching valve 4, tab +5,
It has a cartridge 6 and a cover 7 as its main components, and is removably attached to a faucet 8 through a faucet connection part 2. Switching valve 4V
i. By rotating the knob 5, the water flow can be switched to the raw water port 10 or the purified water port 11 in the switching passage 9. A filter 2 is provided at the bottom of the cartridge 6 to enhance the filtration effect, and an outflow passage 13 further includes
It opens to the water purification port 11. The cartridge 6 is provided with an inflow passage 14 that faces the switching passage 9 and communicates with a stagnation part 15 between the cover 7 and the water to be treated, which is evenly distributed by the strainer 6, into the stagnation part. 15 to reach the filling material 17 inside the cartridge 6. The filler 17 is granular activated carbon 1 whose main purpose is to remove chlorine and remove beauty.
8 and a granular mineral material 19 whose main purpose is to elute mineral components.

When raw water is supplied, the water to be treated is discharged without being treated in the order of faucet 8 → switching valve 4 → raw water inlet 10, but when treated water is supplied, it is switched at switch yP4 and is passed through switching passage 9 → inlet passage 1.
The water flows in the order of 6→retention chamber 15→optical filler 17→filter 12→outflow passage 13→water purification port 11 and is processed.

Since the water to be treated is intended for drinking, the concentration of mineral components to be eluted needs to be maintained at a constant level close to that of natural water. In other words, it is necessary to ensure that the water is eluted moderately during the water flow to ensure a certain amount or more of elution, and on the contrary, when the water flow is stopped, the water does not dissolve excessively in the water to be treated that remains together with the mineral material 19. For example, the hardness component must not be 5.
The hardness of the water to be treated, which is 0 mg/l, must be kept within a potable range, such that the hardness is between 70 and 1 somg/l.

The mineral material 19 according to the embodiment of the present invention can satisfy this condition, and its cross-sectional structure is as shown in FIG. That is, the mineral material 19 is made by mixing powder of mineral components such as chlorides or hydroxides of mineral metals such as calcium, sodium, and potassium with polyglobylene resin and molding the mixture into granules with low foaming.
21 is a resin part, 21 is a mineral component part, and 22 is a bubble.

In water, the mineral component portion 21 is gradually eluted, and while the air bubbles 22 are in communication with the outside of the granular mineral material 19, pores 23, as shown in FIG. 3, are grown. In this case, the inside of the hole 23 is always saturated with mineral components and dissolved at a tO concentration, but on the surface of the mineral material 190, fluid t&
24 is under pressure, and the diffusion resistance of this fluid film 24 always suppresses elution into water. During water flow, the diffusion resistance of the fluid film 24 decreases due to the flow rate, making it easier to diffuse through the pores 23 to prevent minerals from decreasing in concentration in the water to be treated, and when the minerals stagnate, the diffusion resistance becomes extremely large.
It is difficult to elute from the pores 23, and on the contrary, it is possible to prevent the temperature from rising to 111 degrees. The smaller the size of the pores 23, the more convenient it is to suppress variations in the mineral bathing rate within the pores 23, but a device with a size of several mIJm to several tens of μm is preferable. Arrows in the figure indicate elution paths of mineral components. At the stage of growth of the pores 23, the air bubbles 22 can accelerate the growth of the pores 23 by their volume, increasing the amount of saturated liquid of mineral components stored inside the pores 23, and increasing the amount of the saturated liquid of the mineral component. The replenishment of mineral components in response to changes in the diffusion rate is ensured, making it easier to suppress variations in the mineral m1 degree. In addition, since a large number of adjacent holes 23 can be communicated through the bubbles 220, mineral components within the holes 23 can be averaged, making it easier to compensate for imbalances or deficiencies in mineral concentration.

Since the individual shapes of the resin part 20ri and the mineral material 190 are maintained, the shape of the pores 23 can be maintained, and the volume and filling state of the mineral material 19 as a whole can be maintained, so that mineral components elute due to changes in water flow. performance can be prevented.

Mineral material 19 is a film molded product, so the shape of the
It is also suitable for mass production because you can freely choose the shape that suits your production equipment, such as spherical or cylindrical.

The material of the resin portion 20 is not limited to polypropylene, but may be an insoluble material such as polyethylene or polyethylene depending on various conditions such as the filling structure and water quality.

〔Effect of the invention〕

According to the present invention, it is possible to provide a water* regulating material that effectively controls the concentration of components to be bathed within a certain range without using complicated mechanical or electrical means.

゛ Also, the insoluble component is a resin such as polypropynone,
By using a mineral component as the soluble component, it is possible to provide a light filler for eluting mineral components, which is effective for water purifiers and the like.
