In the mixing tank in the past, when mixing clorox and acid among the Xiang Yuanshui, clorox may directly contact with acid, if clorox directly contacts with acid, pH is reduced to less than 4.5, then produces chlorine.Therefore in the mixing tank in the past, the troubled water according to clorox and acid can partly produce chlorine, must be arranged on from mixing tank and chlorine is discharged to the mechanism that the chlorine of discharging is handled outside the time.
Therefore, developed and made the mixing tank that does not produce chlorine when in former water, mixing clorox and acid.Adopt the mixing tank of the design that does not produce chlorine to be shown in Fig. 2 here.Mixing tank (mixing device) 10 has the shell 12 of cube shaped, and the inside of this shell 12 forms former water passage 14, from the interflow path 20 at this former water passage 14 ramose, first path 16 and alternate path 18, first path 16 and alternate path 18 interflow.In addition, shell 12 can adopt connection to substitute the form of cube shaped corresponding to the form of the pipeline of each path.The former water ingress pipe 22 that is connected with former water passage 14 is installed on the shell 12, and former water is imported into former water passage 14 from former water ingress pipe 22, and former water is divided into first path 16 and alternate path 18 from former water passage 14 and flows.Be equipped with on the shell 12 and collaborate the mixing tube 24 that path 20 is connected, the water that arrives interflow path 20 is discharged to the outside through mixing tube 24.
Import clorox from first electromagnetic pump 26 through first connecting path 28, first vacuum breaker 30 and first ingress pipe 32 midway at first path 16.Be opened on the entad in the cross section of first path 16 for the front end opening that makes the clorox of deriving from first ingress pipe 32 drop into first path, 16, the first ingress pipes 32 reliably by the running of first electromagnetic pump 26.Import acid such as hydrochloric acid or acetate from second electromagnetic pump 34 through second connecting path 36, second vacuum breaker 38 and second ingress pipe 40 midway at alternate path 18.The front end opening that acid such as hydrochloric acid of deriving from second ingress pipe 40 for the running that makes by second electromagnetic pump 34 or acetate drop into alternate path 18, the second ingress pipes 40 reliably is opened on the entad in the cross section of alternate path.
The aperture position of first path, 16 internal ratios, first ingress pipe 32 more downstream side (interflow path 20 sides) possess agitator 42, the aperture position of alternate path 18 internal ratios second ingress pipe 40 more downstream side (interflow path 20 sides) possess agitator 44.In addition, the inside of mixing tube 24 also possesses agitator 46. Agitator 42,44,46 further mixes the mixing water of former water and soup, and its material uses can be by the material of acid corrosion.Agitator 42,44,46 uses shape for example shown in Figure 3, but its shape is not limited to shape shown in Figure 3.
As above in the mixing tank 10 of Gou Chenging, import the former water of former water passage 14 from former water ingress pipe 22, half of its import volume is imported into first path 16, its import volume remaining half be imported into alternate path 18.In first path 16, the clorox of deriving from first ingress pipe 32 is added to the former water by it, and former then water and clorox mix by agitator 42, make the mixing water of former water and clorox.In the alternate path 18, the acid of deriving from second ingress pipe 40 is added to the former water by it, and former then water and acid mix by agitator 44, make the mixing water of former water and acid.The mixing water of the mixing water of former water and clorox and former water and acid is by interflow path 20 interflow, and former then water, clorox and acid mix by the agitator in the mixing tube 24 46, and formation can be killed the sterilization water of various bacterium.Then, sterilization water is discharged to the outside from mixing tube 24.
In the mixing tank 10 shown in Figure 2, as the clorox of soup with directly do not contact as acid such as the hydrochloric acid of soup or acetate.That is, clorox is diluted by former water, and acid is also diluted by former water, and diluted clorox and diluted acid are mixed by the agitator in the mixing tube 24 46.Clorox and acid are all diluted, can not produce chlorine because of the mixing between the dilution water.As mentioned above, by using mixing tank shown in Figure 2 10, can under the state that does not produce chlorine, mix former water, clorox and acid and generation sterilization water.
As the method that in former water, drops into clorox and acid, as shown in Figure 2, the central position that the front end opening of first ingress pipe 32 is opened on the passage sections of first path 16 is arranged, the front end opening of second ingress pipe 40 is opened on the method for central position of the passage sections of alternate path 18.Input clorox and acid have other method among the Xiang Yuanshui, and other method is shown in Fig. 4 and Fig. 5.Fig. 4 and Fig. 5 represent to drop into to first path 16 from first ingress pipe 32 example of clorox.At first path 16 connecting path 50 that is connected in vertical direction with this first path 16 is set midway.The valve 52 that is formed by the pliability material that is generally known as duckbill valve is installed at the peristome front end of first ingress pipe 32.This valve 52 is the shape of the tubular with end face 54, is formed with the jet orifice 56 of slit-shaped on the end face 54.After this valve 52 was installed on the peristome of first ingress pipe 32, (than the peristome position of first ingress pipe 32 more on the front) formed and accumulates space 58 in the inside of valve 52.
The end face 54 of this valve 52 be disposed at from the enough inside of the connecting path 50 of inboard of the link position of first path 16.First electromagnetic pump 26 (second electromagnetic pump 34) turns round off and on, and at the running intermittence of first electromagnetic pump 26, the jet orifice 56 of valve 52 is closed, and clorox can not sprayed from valve 52.On the other hand, during 26 runnings of first electromagnetic pump, the clorox extruding of sending from first electromagnetic pump 26 lodges in the clorox that accumulates in the space 58, opens the jet orifice 56 of valve 52, and clorox is sprayed from this jet orifice 56.Clorox relies on the jet power of blowing loophole 56 to arrive first path 16, and former water and clorox mix in first path 16.That is, borrow the gesture of first electromagnetic pump 26 and valve 52 to be ejected in first path 16, the jet orifice 56 (peristome of first ingress pipe 32) of valve 52 is disposed at the inner side of connecting path 50 in order to make clorox.

The best mode that carries out an invention
Below, the present invention will be described based on accompanying drawing.Fig. 1 is the sectional view of an embodiment of the major portion of expression sterile water producing apparatus of the present invention.Among Fig. 1, represent same parts with the Ref. No. that the Ref. No. shown in Fig. 2 and Fig. 4 is same.In addition, among Fig. 1, expression drops into clorox the example of first path 16 from first ingress pipe 32.The present invention is not for using the device of Fig. 4 and valve 52 shown in Figure 5, and the peristome of first ingress pipe 32 is disposed at the inside of connecting path 50.Here, shell 12 is under the situation of pipeline, and connecting path 50 adopts the rounded section of diameter D.Connecting path 50 better is the path of the cross section circle of employing and first path, 16 same diameter D, but is not limited thereto.In the sterile water producing apparatus, generally use the pipeline of the inner diameter d about 10mm≤D≤36mm, the pipeline about D=22mm particularly, but the size of inside diameter D is not limited thereto.In addition, it all is the situation of square-section that the connecting path 50 and first path 16 are also arranged, under this situation, with big limit as D.In addition, the distance with the position of the front end opening of in the connecting path 50 and the link position first path 16 and first ingress pipe 32 is made as B.Among the present invention, the peristome of first ingress pipe 32 is disposed at the inside of connecting path 50 with the condition of 1/3D≤B≤2.5D.
In addition, among the present invention, if will be made as P with the pressure of the former water that passes through first path 16 in the link position of connecting path 50, the pressure that will export to the clorox in the connecting path 50 from the peristome of first ingress pipe 32 is made as P ', then is set at 1/8P '≤P<P '.
When the peristome of first ingress pipe 32 being disposed at the inside of connecting path 50 with the condition of 1/3D≤B≤2.5D, be set at 1/8P '≤P<P ', from first ingress pipe 32 export to the clorox of inside of connecting path 50 connecting path 50 with link position first path 16 near produce the whirlpool 60 that has mixed former water.This whirlpool 60 exports to connecting path 50 and the clorox that directly do not arrive first path 16 forms by the part of the former water that passes through first path 16 that enters connecting path 50 with from first ingress pipe 32.The shape of this whirlpool 60 forms elliptical shape or forms different therewith shapes according to the length of B.By will being arranged in the scope of 1/3D≤B≤2.5D apart from B, the part (half of whirlpool 60 sizes is following) of the whirlpool 60 that is formed by clorox and former water protrudes in first path 16.By adopting the scope of 1/8P '≤P<P ', make the clorox of deriving directly not arrive first path 16 from first ingress pipe 32.
Protrude in first path 16 by a part that makes the whirlpool 60 that contains clorox, the part of clorox that running by first electromagnetic pump 26 (with reference to Fig. 2) exports to the inside of connecting path 50 from first ingress pipe 32 is mixed in the former water by first path 16, and it most forms whirlpool 60 and residues in the connecting path 50.Then, in the time before the running next time of first electromagnetic pump 26, whirlpool 60 contained clorox progressively are mixed in the former water that flows through first path 16 with whirlpool 60.At this moment, by 1st time the clorox of first electromagnetic pump 26 in first ingress pipe 32 exports to connecting path 50 the 2nd time clorox almost all was mixed in former water by first path 16 before first ingress pipe 32 is derived.Thus, the blending ratio that can make former water and clorox constant mixing water always.
Regulate above-mentioned length apart from B at interval by the running according to first electromagnetic pump 26, the clorox of the 1st derivation can all drop into before the 2nd time is derived and be mixed in the former water that flows through first path 16.Satisfy 1/3D≤B≤2.5D when as previously mentioned, a part that contains the whirlpool of clorox protrudes in first path 16.B is during less than 1/2D, most protruding in first path 16 of the whirlpool 60 of clorox, so from exporting to before the 2nd time the derivation of clorox of the 1st time clorox, all clorox of deriving for the 1st time just are mixed in the former water that flows through first path 16, produce the state that only former water flows through in first path 16.On the other hand, B is during greater than 2.5D, and from the 1st time clorox no show first path 16 that first ingress pipe 32 is derived, before the derivation of the 2nd time clorox, the 1st time clorox all is not mixed in the former water that flows through first path 16.Thus, produce the problem that to make the mixing water of former water and clorox equalization in first path 16.
In addition, P is less than 1/8P ' time, and the clorox of deriving from first ingress pipe 32 arrives first path 16, and P can't guarantee the derived quantity of clorox greater than P ' time, so the scope of P is made as 1/8P '≤P<P '.
In addition, among Fig. 1, the structure that will be mixed in the former water that flows through first path 16 from the clorox that first electromagnetic pump 26 is derived is illustrated, and the structure that will be mixed in from the acid that second electromagnetic pump 34 (with reference to Fig. 2) is derived the former water that flows through alternate path 18 also is same (1/3D≤B≤2.5D, 1/8P '≤P<P ').In the sterile water producing apparatus, the running that has first electromagnetic pump 26 that only extends at interval reduce the situation of effective free chloro concentration and the running of second electromagnetic pump 34 that only extends at interval and the situation of reduction pH value.Therefore, have only to be used in and derive the situation at the position of clorox, only be used in by second electromagnetic pump 34 and second ingress pipe 40 and derive the situation at position of acid and the situation that is used in two positions by first electromagnetic pump 26 and first ingress pipe 26.
