  Next, embodiments of the present invention will be described with reference to the drawings. First, with reference to FIG. 1, the external appearance and function of the water stirring apparatus 1 will be described. The water stirring device 1 has a function of obtaining treated water having improved water characteristics by stirring raw water such as tap water. As shown in FIG. 1, the water agitation apparatus 1 mainly includes a substantially cylindrical agitation processing unit 2 that causes water to be treated to flow inside. The agitation processing unit 2 is configured such that the top of a bottomed cylindrical container 3 is closed with a lid member 4 and the lid member 4 is fixedly attached to the container 3 with a cap member 5.

  A water inlet 6 is provided on the side surface near the lower end of the container 3, and a joint member 6 a fastened to the water inlet 6 is connected to a raw water supply source 7 such as a water tap. A drainage port 8 is provided on the upper surface of the lid member 4, and a joint member 8 a fastened to the drainage port 8 is connected to a treated water reservoir 9 such as a water storage tank. By operating the raw water supply source 7, raw water having a predetermined pressure is supplied into the container 3 through the water inlet 6. The supplied raw water is stirred by flowing upward in the container 3. The treated water modified by stirring is sent to the treated water reservoir 9 through the drain port 8 and stored.

At this time, when the lid member 4 presses the O-ring 3d, the contact surfaces of the lid member 4 and the flange portion 3c are sealed.

  The inside of the container 3 is provided between the water inlet 6 and the drain 8 by a plurality of partition plates (here, the first partition plate 11, the second partition plate 12, and the third partition plate 13). , And partitioned into a plurality of sections (here, four sections of a first section S1, a second section S2, a third section S3, and a fourth section S4). A plurality of flow holes 10 are formed in the first partition plate 11, the second partition plate 12, and the third partition plate 13 in an arrangement pattern defined for each.

  In the container 3 having the above-described configuration, the water inlet 6 for introducing the raw water (arrow a) supplied from the raw water supply source 7 (see FIG. 1) is provided on the side surface of the first section S1 located at the lower part (one end). It has been. The raw water introduced into the container 3 flows in the flow direction (arrow b) from the one end portion on the upstream side to the other end portion on the downstream side in the cylindrical portion 3a. In this flow, the plurality of flow holes 10 formed in the first partition plate 11, the second partition plate 12, and the third partition plate 13 that partition the first section S1 to the fourth section S4 are in the flow direction ( Water flows from the upstream compartment in arrow b) to the adjacent downstream compartment.

  In this water flow process, the raw water has its water characteristics modified by flowing through the flow holes 10 of the first partition plate 11, the second partition plate 12, and the third partition plate 13. Sequentially changes to quality treated water. The water reforming effect in the present embodiment is that the flow form when flowing to the downstream compartment through the flow hole 10, that is, the water to be reformed is injected into the downstream compartment in the form of a submerged jet. It is obtained by microscopic stirring action of water. A drain port 8 is provided on the upper surface of the fourth section S4 located at the upper part (the other end part) of the container 3. The treated water that has reached the fourth section S4 is discharged through the drain port 8 (arrow c) and stored in the treated water reservoir 9 (see FIG. 1).

  Here, a method of mounting the first partition plate 11, the second partition plate 12, and the third partition plate 13 on the container 3 will be described. In the example shown in the present embodiment, as shown in FIG. 3, a plurality of (four in this case) projecting from the lower surfaces of the first partition plate 11, the second partition plate 12, and the third partition plate 13. ) First leg member 21, second leg member 22, third leg member 23, and fourth leg member 24 similarly projecting from the lower surface of the lid member 4, the first partition plate 11, The second partition plate 12 and the third partition plate 13 are held at predetermined positions inside the cylindrical portion 3a.

  That is, depending on the length dimensions of the first leg member 21, the second leg member 22, the third leg member 23, and the fourth leg member 24, the first section S1 to the fourth section S4 in the cylindrical portion 3a. The partition dimensions D1 to D4 can be set to desired dimensions, respectively. In the example shown in the present embodiment, the partition size D2 to the partition size D4 of the second partition S2 to the fourth partition S4 are set to the same size, and only the partition size D1 of the first partition S1 is set larger than the other partitions. Is shown.

  In addition, as a structure which arrange | positions the 1st partition plate 11, the 2nd partition plate 12, and the 3rd partition plate 13 in a predetermined position in the inside of the cylindrical part 3a, and forms 1st division S1-4th division S4. Various forms other than the example shown in the present embodiment can be adopted. For example, the first leg member 21, the second leg member 22, the third leg member 23 and the first partition plate 11, the second partition plate 12, the third partition plate 13 and the lower surface of the lid member 4 Instead of projecting the fourth leg member 24, a ring-shaped spacer having a diameter size fitted to the inner periphery of the cylindrical portion 3a and having a length of the partition dimension D2 to the partition dimension D4 is replaced with the first partition plate 11, You may make it interpose between each of the 2nd partition plate 12, the 3rd partition plate 13, and the cover member 4. FIG.

  In any of the above-described configurations, the first partition plate 11, the second partition plate 12, and the third partition plate 13 are all detachable from the container 3. Further, the arrangement intervals of the first partition plate 11, the second partition plate 12, and the third partition plate 13, that is, the partition dimensions D1, D2, D3, and D4 of the first partition S1 to the fourth partition S4 are desired dimensions. The setting is variable. Furthermore, since the first partition plate 11, the second partition plate 12, and the third partition plate 13 are detachable, the arrangement order of these partition plates is also variable.

  Thereby, in the water treatment operation for reforming the characteristics of the water by sequentially passing the raw water through the first partition plate 11, the second partition plate 12, and the third partition plate 13 having different arrangement patterns of the flow holes 10, It is possible to repeatedly try changing the partition dimensions D1, D2, D3, and D4 and changing the arrangement order of the first partition plate 11, the second partition plate 12, and the third partition plate 13. ing. Thereby, conditions for obtaining a desired reforming effect can be easily obtained.

  Next, the arrangement pattern of the flow holes 10 in the first partition plate 11, the second partition plate 12, and the third partition plate 13 will be described. As described above, the reforming effect by the stirring of water in the present embodiment is an irregular non-uniformity caused by injection in the form of a submerged jet from the upstream section to the downstream section through the flow hole 10. Obtained by steady flow conditions. In such a water reforming method, it is necessary to exclude the flow of water inside the container 3 from being in a steady state.

  For this reason, in this Embodiment, about one division provided by partitioning the inside of the container 3, the several flow hole 10 formed in the partition plate located in an upstream, and the partition located in the downstream of this division The first partition plate 11 and the second partition plate are different from the plurality of flow holes 10 formed in the plate so that the arrangement pattern in which the arrangement positions of the flow holes 10 and the hole size d (see FIG. 7) are combined is different. 12, the arrangement pattern of the flow holes 10 in the third partition plate 13 is determined.

  First, with reference to FIG. 4, the arrangement pattern employed in the first partition plate 11 will be described. On the upper surface of the first partition plate 11 shown in FIG. 4, a plurality of flow hole groups G10 in which a plurality (here, five) of flow holes 10 are formed in a predetermined region (here, a circular region) are arranged. ing. Here, the flow hole group G10 has an arrangement form in which the flow hole group G10 disposed at the center of the first partition plate 11 is surrounded by a plurality (here, five) of flow hole groups G10 from the periphery. The hole size d of the flow holes 10 may be the same size or may vary depending on the position of the flow holes 10 in the flow hole group G10.

  Next, with reference to FIG. 5, the arrangement | sequence pattern employ | adopted as the 2nd partition plate 12 is demonstrated. On the upper surface of the second partition plate 12 shown in FIG. 5, first flow hole arrays L10 are arranged in a radial pattern having an arbitrary equal distribution (eight distributions here) from the center of the second partition plate 12. The first flow hole array L10 includes a plurality of flow holes 10 arranged in a straight line. The hole size of the flow hole 10 in the first flow hole row L10 is a form in which two sizes of large and small are mixed. Further, the second partition plate 12 is provided with a second flow hole array C10 including a plurality of flow holes 10 arranged concentrically with a common outer shape and center point of the second partition plate 12. In the example shown here, it is an arrangement form in which two types of second flow hole arrays C10 having different concentric dimensions are mixed.

  Next, with reference to FIG. 6, the arrangement | sequence pattern employ | adopted as the 3rd partition plate 13 is demonstrated. On the upper surface of the third partition plate 13 shown in FIG. 6, a plurality (eight in this case) extending while curving from the central region of the third partition plate 13 toward the outer edge of the third partition plate 13. The third flow hole array CV10 is arranged. The third flow hole array CV10 includes a plurality of flow holes 10 arranged in a curved shape having an arbitrary shape. Here, although the example which arranged the thing of a common hole size as the flow hole 10 which comprises the 3rd flow hole row | line | column CV10 is shown, you may mix the flow hole 10 of a different hole size.

  The first partition plate 11, the second partition plate 12, and the third partition plate 13 shown in FIG. 4, FIG. 5, and FIG. 6 described above are the flow holes 10 in the partition plate mounted inside the container 3. The arrangement pattern is illustrated. Various variations are possible in addition to the arrangement pattern shown here, but basically, a modification of the basic arrangement pattern shown in FIG. 7 or an arrangement pattern in combination of these is used. These basic arrangement patterns include a first flow hole array L10 shown in FIG. 7A, a second flow hole array C10 shown in FIG. 7B, and a third flow shown in FIG. 7C. The hole row CV10 and the flow hole group G10 shown in FIG.

  The first flow hole array L10 is composed of a plurality of flow holes arranged in a straight line. The second flow hole array C10 includes a plurality of flow holes arranged in a straight line. The third flow hole array CV10 is composed of a plurality of flow holes arranged in an arbitrary curved shape. The flow hole group G10 shows an arrangement pattern in which a plurality of flow holes are formed in a predetermined region. The actual partition plate includes at least one of the arrangement patterns shown in FIG. Further, the hole size d of the flow holes 10 in these arrangement patterns is determined in consideration of conditions such as the supply pressure of the supplied raw water and the required flow rate of treated water.

  When determining the arrangement pattern of the flow holes 10 in the first partition plate 11, the second partition plate 12, and the third partition plate 13 that are actually used by using these basic arrangement patterns, FIG. The arrangement of the flow holes 10 is set so that the flow condition as shown in FIG. That is, the raw water (arrow d) introduced into the upstream first section S1 in the container 3 passes through the flow holes 10 of the first partition plate 11 and flows to the second section S2 (arrow e). Next, the water in the second section S2 flows through the flow holes 10 of the second partition plate 12 and flows into the third section S3 (arrow f).

  At this time, the arrangement of the flow holes 10 in the first partition plate 11 and the second partition plate 12 is set so that the flow of water in the second section S2 generates as much stirring action as possible. That is, the submerged jet (see arrow e) from the flow hole 10 in the first partition plate 11 on the upstream side of the second section S2 causes the flow hole 10 in the second partition plate 12 on the downstream side of the second section S2. It is made to inject to a position different from a position.

  The same consideration is applied to the arrangement of the flow holes 10 in the second partition plate 12 on the upstream side of the third section S3 and the third partition plate 13 on the downstream side of the third section S3. In this way, by setting the arrangement of the flow holes 10 in the first partition plate 11, the second partition plate 12, and the third partition plate 13, the stirring action of the water flow state in each compartment of the container 3 is achieved. It is possible to set to a state where the maximum is achieved.

  Next, with reference to FIG. 9, the water reforming effect in the water agitator 1 shown in the present embodiment will be described. It should be noted that the following description is only a guess based on the configuration of the present embodiment and has not been verified based on strict technical knowledge.

  FIG. 9 shows the inside of the container 3 through the flow holes 10 formed in the first partition plate 11, the second partition plate 12, and the third partition plate 13 from the upstream partition S (U) to the downstream side. A state in which water flows in the form of a submerged jet in the section S (D) is shown. Water in the upstream section S (U) flows into the flow hole 10 due to a pressure difference from the downstream section S (D) (arrow i). At this time, the downstream section S (D) is already filled with water, and the water that has flowed into the flow hole 10 is ejected into the water in the downstream section S (D) in the form of a submerged jet J ( Arrow j). Then, after flowing through the downstream section S (D) in the form of a jet according to the pressure difference, it diffuses (arrow k) and integrates with the surrounding water.

  In such a submerged jet J, a large number of annular vortices Vc are generated from the edge of the flow hole 10. These annular vortices Vc grow into large annular vortices Vc by repeating coalescence in the process of moving together with the submerged jet J, and then collapse and disappear. In the process from generation to disappearance of the annular vortex Vc, a fine vortex is generated from the annular vortex Vc and diffuses around the submerged jet J.

  Since the fine vortex has a reforming action that microscopically stirs water and homogenizes water molecules, a large number of flow holes 10 are formed as in the water stirrer 1 shown in the present embodiment. The above-described reforming action is applied to the water flowing in the container 3 having a configuration in which the formed partition plates are provided in a plurality of stages. That is, in each of the first partition plate 11, the second partition plate 12, and the third partition plate 13, the annular vortex Vc generated around the submerged jet J for each flow hole 10 is the surrounding flow hole 10. Due to the interference with the annular vortex Vc, a more complicated fine vortex is generated and a higher stirring effect is obtained.

  And in the water stirring apparatus 1 shown in this Embodiment, since the foreign material which prevents the flow of water, such as a filter medium, does not exist in 1st division S1-4th division S4, the production | generation of the submerged jet J may be prevented. Absent. Further, as described with reference to FIG. 8, in the present embodiment, the submerged jet J from the flow hole 10 of the upstream partition plate is injected at a position different from the position of the flow hole 10 in the downstream partition plate. Since the arrangement pattern of the flow holes 10 is set as described above, it is possible to enhance the stirring action due to the flow of water in each compartment of the container 3.

  The above-described reforming effect by the water agitation device 1 is based on a speculation that can be inferred from the configuration of the water agitation device 1. However, it is confirmed that the raw water (tap water) is stirred by the water stirrer 1 shown in the present embodiment to reduce the oxidation-reduction potential of the water to be treated, that is, the raw water can be reduced. Has been. In the trial by the inventor, the raw water whose oxidation-reduction potential was about 450 mV was treated with the water stirring device 1 to reduce the oxidation-reduction potential to about 150 mV, and the reduction effect was empirically confirmed. ing.

  As described above, the water agitation device 1 shown in the present embodiment is a water agitation device that obtains treated water with improved water characteristics by agitation of raw water, and the raw water is introduced into one end. A water outlet 6 for discharging the treated water at the other end, a container 3 for flowing water in a flow direction from one end to the other end, and the water outlet 6 and the drain for the container 3. A plurality of partition plates that are partitioned into a plurality of compartments between the mouth 8 and a plurality of flow holes 10 that are formed in the partition plates and allow water to flow from the upstream compartment to the adjacent downstream compartment in the flow direction. It has a configuration.

  In this configuration, the plurality of flow holes 10 formed in the partition plate located on the upstream side of one partition and the plurality of flow holes 10 formed in the partition plate located on the downstream side of the partition are flow holes. The arrangement pattern which combined 10 arrangement positions and hole sizes is different. Thereby, the flow state of the water in each compartment of the container 3 can be set to a state in which the stirring action is maximized, and the process has been improved by providing sufficient stirring action to the raw water with a simple configuration. You can get water.

  The water agitation apparatus of the present invention has an effect that it can obtain treated water with improved characteristics by exerting sufficient agitation action on the raw water with a simple configuration, and has characteristics of raw water such as tap water. It is useful in the field of improved water treatment.
