Description

  The present invention relates to a water quality improving device used to improve water quality.

  Patent Document 1 discloses a washing auxiliary article for washing, characterized in that a plurality of particles containing 50% by weight or more of a metallic magnesium (Mg) simple substance are enclosed in a water-permeable net body. This laundry auxiliary product for washing is put into a washing tub of a washing machine together with a detergent for washing and is used for washing articles to be washed. More specifically, it is put in the washing tub at the time of use, and after use, it is removed from the washing tub. Taken out.

In Patent Document 1, when the washing auxiliary article for washing is put in a washing tub, the reaction of the following formula (1) occurs, that is, metal magnesium (Mg) simple substance reacts with water to generate hydrogen (H ₂ ). And magnesium hydroxide (Mg (OH) ₂ ) are generated.
Mg + 2H ₂ O → H ₂ + Mg (OH) ₂ (1)

  Further, in Patent Document 1, the action or function based on this reaction is described as follows. This reaction occurs because the redox reaction with water occurs due to the ionization tendency of magnesium, but since magnesium has a smaller ionization tendency than calcium and sodium, it reacts with water at room temperature relatively slowly to produce hydrogen. To occur. In this way, it is considered that hydrogen or the like generated in the washing liquid during washing promotes the action of removing the dirt of the surfactant by the following first to third actions. The first effect is that hydrogen has a very small atomic diameter, and when it is present in the washing liquid, it acts to permeate the surfactant deep into the texture of textile products such as clothes, so the surfactant removes dirt. The range covered can be expanded. In particular, this effect is remarkably exhibited when the textile product is knitted with extremely fine yarn. As the second effect, hydrogen has a function of emulsifying the dirt, and therefore the degree of removing the dirt by the surfactant can be increased. As a third effect, since many stains are basically acidic, adding Mg particles to the washing liquid to make the washing liquid weakly alkaline also promotes the action of removing the stains of the surfactant. ..

Patent Document 2 is a washing tub including a plurality of particles of magnesium material, which is the same as the above-mentioned laundry auxiliary product described in Patent Document 1, without using a laundry detergent, together with an article to be washed. Disclosed is the use of laundry wastewater as a fertilizer for plant cultivation after being thrown into and washed. According to the description of Patent Document 2, since this laundry wastewater contains magnesium hydroxide (Mg (OH) ₂ ), this laundry wastewater is used as a fertilizer, and magnesium hydroxide fertilizer (magnesium hydroxide (Mg (Mg The plant can be cultivated by effectively reusing it instead of OH) ₂ )).

Here, as can be understood from FIG. 1 and FIG. 2, in a circle (not shown) defined in the internal space 12s on an imaginary cross section orthogonal to the axis 10A of the water quality improving device 10, it is arranged to extend in a substantially tangential direction thereof. In addition, the fluid inlet 20 and the fluid outlet 22 are provided for the internal space 12s. Therefore, when the rotary blade 18 rotates based on the fluid flow that flows from the fluid inlet 20 to the internal space 12s and flows out from the fluid outlet 22, power is generated in the shaft portion 18a.

  The stirring blade 14 is provided right above the power generation unit 12 in FIGS. 1 to 3. The stirring blade 14 includes a shaft portion 14a that extends along the axis 10A so as to be rotatable around the axis 10A, and six blade portions 14b that respectively extend from the shaft portion 14a in the radial direction.

Specifically, it is preferable that the metal magnesium (Mg) simple substance is contained in an amount of 50% by weight or more, preferably 80% by weight or more, and more preferably substantially 100% by weight. This “substantially” means “when considering impurities that cannot be completely removed by the refining means that are currently generally known and used on the production base in the field, from the components of the magnesium particles”. Means

  (I) Magnesium ore is contained as a component other than the main component metal magnesium (Mg) which can be contained in the Mg particles, and iron is included in the processes such as magnesium refining and processing. Impurities such as (Fe), aluminum (Al), and zinc (Zn), and (ii) substances that do not inhibit the above-mentioned first action, second action, and third action based on the reaction of the above formula (1) can be mentioned. ..

  The average particle diameter of the Mg particles 17 is preferably as small as possible from the viewpoint of increasing the surface area per unit volume and increasing the generation amount of the reaction product of the above formula (1). However, as the particle size becomes smaller, the strength of the particle decreases and the handling becomes difficult. Therefore, from the viewpoint of production and use, the average particle diameter of the Mg particles is preferably 1.0 to 9.0 mm, and 3.0. It is more preferably ˜7.0 mm, and most preferably 4.0 to 6.0 mm. Note that this does not limit the size of the Mg particles 17.

Further, the first housing member 32 may be manufactured by joining the central shaft portion 32a and the peripheral portion thereof to the other portions. It should be noted that various sealing members, for example, O-rings, may be provided at the connection between the housing members.

  The inner space 12s of the power generation unit 12 is substantially defined by the first housing member 32 and the second housing member 34. As shown in FIG. 3, the shaft portion 18a of the rotary blade 18 is installed by inserting the central shaft portion 32a of the first housing member 32, and is rotatable around the central shaft portion 32a. Here, the central shaft portion 32a of the first housing member 32 has a circular cross section, and the hole portion 18d corresponding to that of the first end portion 18c of the shaft portion 18a of the rotary blade 18 also has a circular cross section.

  The shaft portion 18 a of the rotary blade 18 penetrates the second housing member 34 and extends into the third housing member 36. A seal member 42 is provided at a penetrating portion of the shaft portion 18a of the second housing member 34 so as to rotatably support the shaft portion 18a and suppress liquid leakage, specifically water leakage. On the upper side of FIG. 3 from the sealing point, a portion (hereinafter, intermediate portion) 18e of the shaft portion 18a of the rotary blade 18 is formed in a polygonal cross section, here, a quadrangular cross section. The shaft portion 14a of the stirring blade 14 into which it is inserted has a hole 14c having a shape and size corresponding to the intermediate portion 18e. The intermediate portion 18e of the rotary blade 18 extends along the central axis of the rotary blade 18, and the hole 14c of the stirring blade 14 extends along the central axis of the stirring blade 14. Therefore, when the intermediate portion 18e of the shaft portion 18a of the rotary blade 18 is inserted into the hole 14c of the shaft portion 14a of the stirring blade 14, the shaft portion 14a of the stirring blade 14 is coaxially connected to the shaft portion 18a of the rotary blade 18. , Can be rotated integrally. The cross-sectional shape of the intermediate portion 18e and the cross-sectional shape of the hole 14c of the stirring blade 14 are not limited to a quadrangle, and may be, for example, a hexagon, or a circular shape with an engaging portion so that they are integrally fitted. May be Then, in order to integrally fix the stirring blade 14 to the rotary blade 18 in a state where the intermediate portion 18e of the shaft portion 18a of the rotary blade 18 is inserted into the hole 14c of the shaft portion 14a of the stirring blade 14, the shaft of the stirring blade 14 is integrally fixed. The nut 44 is screwed to the second end portion of the shaft portion 18a of the rotary blade 18 penetrating the portion 14a, that is, the screw portion 18f.

  The method of mounting, supporting, and / or fixing the shaft portion 18a of the rotary blade 18 and the shaft portion 14a of the stirring blade 14 is not limited to this embodiment. Various configurations or methods that allow the stirring blade 14 to rotate with the rotation of the shaft portion 18a of the rotary blade 18 can be adopted. For example, the seal member 42 may be omitted and various support members may be provided.

  Water quality improvement in the water quality improvement device 10 having the above configuration, specifically, generation of alkaline water (alkaline water) will be described with reference to FIG. FIG. 4 is a diagram for explaining a usage state of the water quality improvement device 10. The water quality improving device 10 is provided in the water flow path. Further, in FIG. 4, the fluid outlet 22 of the water quality improving device 10 is connected to the water inlet 24 by the hose 46. That is, the power generation unit 12 and the water passage unit 16 are associated with each other so that the water that has passed through the power generation unit 12 flows into the water passage unit 16. A hose 48 is connected to the fluid inlet 20 so that the water having a predetermined pressure, specifically, the water flowing out from the water faucet flows into the fluid inlet 20, and the hose 50 is connected to the water outlet 26. The hose 50 is connected to a washing machine, for example. As described above, in the water quality improving device 10 of FIG. 4, the liquid used to generate the power in the power generating part 12 of the water quality improving device 10 is water, and the water is passed through the power generating part 12 and then water. It passes through the passing portion 16.

In the water quality improving device 10 of FIG. 4, when the water faucet (not shown) that is the water supply source is opened, the flow of the water (arrow W1) flowing from the fluid inlet 20 into the internal space 12s of the power generation unit 12 causes the rotor blades 18 to move. Rotates (arrow R1). As a result, the stirring blade 14 rotates (arrow R2). Water (arrow W2) flowing out of the internal space 12s through the fluid outlet 20 flows into the internal space 16s of the water passage portion 16 in which the stirring blade 14 is rotating (arrow W3) through the water inlet 24. .. The water flows out of the water outlet 26 while flowing in the internal space 16s of the water passage portion 16 and in contact with the Mg particles 17 (arrow W4). Thus, as can be understood from the above formula (1), the water flowing out from the water outlet 26 contains Mg (OH) ₂ and is prone to alkali, and exhibits weak alkalinity of about pH 8.0 to 9.0, for example. ..

  Thus, since the Mg particles 17 are contained in the internal space 16s in which the stirring blade 14 rotates, the Mg particles are also stirred. The oxide particles on the surface of the Mg particles tend to be removed or suppressed by rubbing with other Mg particles or by contacting with the stirring blades 14. Therefore, the Mg particles 17 are easily oxidized, but the reaction of the above formula (1) can be continued for a longer time. Therefore, according to the water quality improving device 10, the quality of the water flowing therethrough can be continuously improved, and preferably the alkali-prone water can be continuously generated. Then, the water quality improving device 10 is installed in the water intake part of the washing machine or installed in the agricultural water intake part, so that the user does not feel annoyed and the alkali-prone water is added. Can be used for washing and agricultural water.

  As described above, the stirring blade 14 is a stirring unit configured to generate stirring between the plurality of Mg particles 17 and water in the water passage portion 16. However, stirring means other than the stirring blade 14 may be provided. Below, the water quality improvement apparatus 110 which concerns on 2nd Embodiment provided with the stirring means other than the stirring blade 14 is demonstrated.

  In addition, in the water quality improving device 10 of the first embodiment, the fluid supplied to the power generation unit 12 is water, and this water was supplied to the water passage unit 16. It may be different from the water supplied to the water passage portion 16. However, it is preferable that the fluid supplied to the power generation unit 12 and the water supplied to the water passage unit 16 are the same from the viewpoint of energy saving. Further, in the above embodiment, the power generation unit 12 is configured to generate power by hydraulic power, but it may be configured to include a motor (not shown). In this case, the motor is even better for the environment if it is driven by electricity, for example by photovoltaics.

  Next, the water quality improving device 110 according to the second embodiment of the present invention will be described based on FIG. FIG. 5 is a schematic diagram of the water quality improvement device 110. In the following, differences between the water quality improving device 110 and the water quality improving device 10 of the first embodiment will be mainly described.

  The water quality improving device 110 includes a water passage portion 16 in which a plurality of Mg particles 17 are accommodated and which allows water to pass therethrough. Two water inlets 24 a and 24 b are provided as water inlets in the water passage portion 16. Prepare The first water inlet 24a and the second water inlet 24b have a water passage portion 16 such that the water flowing into the water passage portion 16 from these water inlets causes the plurality of Mg particles 17 to be stirred in the water passage portion 16. That is, it is provided for the internal space 16s. Here, specifically, the first water inlet 24a is configured so that the water flowing into the water passage portion 16 from the first water inlet 24a merges synergistically with the water flowing into the water passage portion 16 from the second water inlet 24b. 24a and the 2nd water inlet 24b are related mutually. As is clear from FIG. 5, the water from the first water inlet 24a and the water from the second water inlet 24b flow in substantially the same direction in the water passage portion 16 as the water inlet 24a and the second water inlet. 24b is provided. This makes it possible to generate a swirling flow, preferably a strong swirling flow, in the water passage portion 16. Therefore, it is possible to cause agitation of the plurality of Mg particles 17 and water. Therefore, collision of the Mg particles 17 or the like may occur, and the oxide film on the surface of them may be reduced, so that it becomes possible to continue the above reaction suitably. In addition, in FIG. 5, the water from the water supply source 112 is divided into two, and the hose 114 is provided so as to flow into the first water inlet 24a and the second water inlet 24b. However, the water supply source of the first water inlet 24a may be independent of the water supply source of the second water inlet 24b.

  Thus, in the water quality improving device 110 according to the second embodiment, the arrangement configuration of the first and second water inlets 24a and 24b causes the plurality of Mg particles and the water to be stirred in the water passage portion 16. Corresponds to the stirring means configured in. However, the number of water inlets is not limited to two, and may be one or three or more. The arrangement configuration of the water inlet directed to generate such a swirling flow is also applicable to the water quality improving device 10 of the first embodiment. In addition, when the arrangement configuration of the water inlet directed to generate the swirling flow is applied to the water quality improving device 10 of the first embodiment, the stirring blade is configured to rotate by the water flow at that time. May be. In this case, the power generation unit 12 may or may not be provided.

  Further, a water quality improving device 210 according to the third embodiment of the present invention will be described with reference to FIG. FIG. 6 is a schematic diagram of the water quality improvement device 210. In the following, differences between the water quality improving device 210 and the water quality improving device 110 of the second embodiment will be mainly described.

  Also in the water quality improving device 210 according to the third embodiment, the arrangement of the water inlet of the water passage portion 16 is a stirring means configured to cause agitation of a plurality of Mg particles and water in the water passage portion 16. Equivalent to. However, the water quality improving device 210 is different from the water quality improving device 110 of the second embodiment in the specific arrangement configuration of the water inlet of the water passage portion 16.

  In the water quality improving device 210, the first water inlet 24a and the second water inlet 24b of the water passage portion 16 have a plurality of Mg particles 17 in the water passage portion 16 in which the water flowing into the water passage portion 16 from the water inlets. It is provided for the water passage portion 16 so as to cause stirring. Here, specifically, the first water inlet 24a and the first water inlet 24a and the first water inlet 24a so that the water flowing into the water passage portion 16 collides with the water flowing from the second water inlet 24b into the water passage portion 16. The two water inlets 24b are related to each other. As is clear from FIG. 6, the water from the first water inlet 24a and the water from the second water inlet 24b flow in a direction substantially opposite to that in the water passage portion 16, so that the water inlet 24a and the second water inlet 24a. 24b is provided. This makes it possible to generate a turbulent water flow, preferably a strongly turbulent water flow, in the water passage portion 16. Therefore, it is possible to cause agitation of the plurality of Mg particles 17 and water. Therefore, collisions between the Mg particles 17 and the like may occur, and the oxide film on the surface of them may be reduced, so that it becomes possible to continue the above reaction in a suitable manner. Note that, in FIG. 6 as well, the hose 114 is provided so that the water from the water supply source 112 is divided into two and flows into the first water inlet 24a and the second water inlet 24b. The water supply source of 24a may be independent of the water supply source of the second water inlet 24b.

  FIG. 7 schematically shows the water quality improvement device 10 according to the first embodiment applied to a washing machine 60 of a coin laundry. Water from the water supply unit, specifically, the water faucet 62 is supplied to the washing tub 68 of the washing machine 60 through the first flow path 66 according to the switching of the valve 64, and the second flow path 70. It may be supplied to the washing tub 68 of the washing machine 60 via the. The valve 64 is configured here as a three-way valve that is automatically switched by the operation of a control device (not shown) accompanying the operation of the washing machine 60. When it is desired to supply hot water as washing water at the time of washing, the first flow path 66 is selected and the water from the tap 62 is supplied to the washing tub 68 via the water heater 72. On the other hand, when supplying water as washing water at the time of rinsing, the 2nd channel 70 is selected and the water from the tap 62 is directly supplied to the washing tub 68. In the washing machine 60 of FIG. 7, the water quality improving device 10 is arranged in the first flow path 66.
