Description

  The present invention relates to a two-component mixing apparatus for mixing two kinds of liquids to obtain a mixed solution, and more specifically, for adjusting the main liquid as a main composition of the mixed solution and the properties of the mixed solution such as the PH value. The present invention relates to a two-liquid mixing apparatus suitable for mixing two types of liquids, and a sterilizing liquid generating apparatus configured to generate a sterilizing liquid with a configuration based on the two-liquid mixing apparatus.

  Conventionally, when obtaining a mixed liquid in which two kinds of liquids are mixed, for example, as disclosed in Patent Document 1, a container configured to allow the liquid stored therein to flow out from a spout provided in the lower part is used. It was.

  Specifically, in the conventional two-component mixing apparatus, two containers disclosed in Patent Document 1 are installed, one of the two types of liquid is stored in one of the two containers, and the other container is stored. Of the two types of liquid, the other liquid is stored. And one liquid is made to flow out from the spout of one container, and this one liquid is received with a cup. Subsequently, when a predetermined amount of one liquid is accumulated in the cup, the two liquids can be mixed in the cup by pouring the other liquid into the cup from the spout of the other container.

The mixed liquid collected from the cup can be used as a sterilizing liquid for vegetables, for example, if mixed with water in a container containing vegetables.
However, since the spout member from which each of the two types of liquid flows out is provided separately for each container and is separated from each other, it is necessary to pour into the cup for each type of liquid. Since the outflow amount fluctuated due to the deviation, it has been difficult to adjust the mixture of the mixed solution.

  Furthermore, since each type of liquid is poured separately into the cup, each time it is necessary to open and close the cock of the spout member, which is cumbersome, and it is difficult to mix homogeneously in the cup. It also had the disadvantage that it could have an adverse effect.

JP 2003-26297 A

  Accordingly, the present invention provides a two-component mixing apparatus that can easily obtain a high-quality mixed solution in which two kinds of liquids are homogeneously mixed, and a sodium hypochlorite aqueous solution having a configuration based on the two-component mixing apparatus. An object of the present invention is to provide a sterilizing liquid generating device configured to be able to generate a high-quality sterilizing liquid mixed with a PH adjusting liquid.

  The present invention provides a first liquid that can be stored inside the apparatus main body, a first container that can flow out from a first liquid outflow portion provided at a lower portion, and a second liquid that stores the first liquid in a smaller amount than the first liquid. A second container that can flow out from the second liquid outflow section provided at the lower part, and a two-liquid outflow cock that flows out two types of liquids, the first liquid and the second liquid, and mixes the two liquids. In the liquid mixing apparatus, the second container is disposed above the first container, the second liquid flowing out from the second liquid outflow portion is guided to the two-liquid outflow cock side, and after the guidance A cock first inflow comprising a liquid guide pipe having a guide pipe outflow portion allowing the second liquid to flow out to the two liquid outflow cock side, and communicating the two liquid outflow cock with the first liquid outflow portion. A cock, a second inflow portion communicating with the guide tube outflow portion, a first liquid and a second liquid With a body composed of a cock liquid outlet portion flowing out, characterized in that the closable constructed and the cock first inlet and the cock second inlet.

  According to the above configuration, since the first liquid and the second liquid are configured to flow out from the common two-liquid outflow cock, the cock attached to the container provided for each type of liquid as in the past is opened and closed separately. Unlike the operation, the first liquid and the second liquid can be flowed out or stopped at the same time only by opening and closing the two-liquid outflow cock, and handling is easy.

  In addition, since the two-component mixing apparatus of the present invention can simultaneously pour two kinds of liquids into a container such as a cup as described above, the two kinds of liquids are mixed with each other and homogenized when poured simultaneously. It is possible to obtain a mixed solution mixed with the above.

Furthermore, as described above, two types of liquid can be poured into a container such as a cup at the same time. Thus, unlike the case where each of the two types of liquid flows out from separate cocks, there is an error in the timing of opening and closing the cocks. Thus, the mixing ratio of the mixed solution is not affected.
Therefore, the first liquid and the second liquid can be mixed in a desired blending ratio in advance.

  In addition, by installing the second container above the first container, the second liquid stored in the second container can increase its potential energy compared to the first liquid stored in the first container. it can.

In other words, the water pressure (outflow pressure) of the second liquid acting at the guide tube outflow portion can be increased by installing the second container above.
As a result, the second liquid stored in the second container can continue to flow out without interruption until the outflow is completed while being in a smaller amount than the first liquid.

  In addition, since the two-component mixing apparatus has a configuration in which the second container is arranged above the first container, it is installed in comparison with the case where the second container and the first container are arranged side by side. The effect that a liquid mixture can be obtained also in a narrow place without requiring a space can also be acquired.

  As an aspect of this invention, the first liquid is a chlorinated alkaline aqueous solution, the second liquid is an acidic aqueous solution, the first container is configured with a larger volume than the second container, and the first liquid outflow portion And a minimum channel cross section between the second liquid outflow portion and the guide tube outflow portion from the first container according to a volume ratio between the first container and the second container. The flow path cross-sectional ratio can be configured such that the second liquid flows out from the second container before the first liquid flows out.

  First, as a premise, for example, when finally obtaining a mixed liquid divided into a plurality of cups, the first liquid and the second liquid flowing out from the two-liquid outflow cock are placed in order in a plurality of cups. The work of repeating pouring at every fixed amount is performed.

  If the second liquid outflow is delayed from the second container rather than the first liquid outflow from the first container, the cup collected immediately before the second liquid outflow is completed. In the mixed liquid, the proportion of the second liquid increases, and the acidic value increases. In such a case, there is a possibility that harmful gas such as chlorine gas is generated from the liquid mixture by lowering the PH value.

  Therefore, as described above, the flow path cross section of the first liquid outflow portion and the minimum flow path cross section between the second liquid outflow portion and the guide tube outflow portion are transferred from the first container to the first liquid. The flow rate of the second liquid from the second container is completed before the second liquid outflow is completed, so that the mixing in the cup collected immediately before the liquid outflow from the two-liquid outflow cock is completed. Even if the proportion of the first liquid which is alkaline increases in the liquid, the acid value does not increase.

  Therefore, even for the mixed solution collected in the cup immediately before the completion of the outflow, a safe mixed solution can be obtained without a risk of generating harmful gases such as chlorine gas.

  Moreover, the said guide pipe outflow part can be distribute | arranged to the inside of said 1st container as an aspect of this invention.

  With the above configuration, the first liquid flowing out from the first outflow portion and the second liquid flowing out from the guide outflow portion are arranged in the first container in the same outflow direction toward the two-liquid outflow cock side. can do.

  Therefore, the first liquid and the second liquid can be allowed to flow into the two-liquid outflow cock under the same conditions, and the mixing ratio of the two types of liquid can be flown out without changing from the cock liquid outflow portion. Can do.

  Furthermore, when almost the entire liquid guide tube is disposed inside the first container, the liquid guide tube does not get in the way as the liquid guide tube is disposed outside the first container, and has a clean and good appearance. can do.

  Further, as an aspect of the present invention, the internal space of the two-liquid outflow cock includes a first liquid flow path communicating between the cock first inflow portion and the cock liquid outflow portion, and a cock second inflow portion and a cock liquid outflow portion. A second liquid channel communicating between the first liquid channel and the partition portion partitioning the first liquid channel and the second liquid channel.

  With the above configuration, the inside of the two-liquid outflow cock can be partitioned into a first liquid flow path and a second liquid flow path through a partition portion, and thus, for example, the liquid flows into the two-liquid outflow cock. The second liquid does not flow back to the first container side through the first cock inflow part, and the first liquid and the second liquid can surely flow out from the cock liquid outflow part.

  Further, as an aspect of the present invention, a flow rate adjusting member that has an opening that allows passage of liquid and adjusts the flow rate according to the opening cross section of the opening, and a first liquid flow rate adjustment that adjusts the flow rate of the first liquid. At least one of a member and a second liquid flow rate adjusting member that adjusts the flow rate of the second liquid, and the first liquid flow rate adjusting member is configured to be exchangeable with each other at the first liquid outflow portion. The two liquid flow rate adjusting members can be configured to be interchangeable with each other in the liquid guide tube.

  With the above configuration, by replacing the first liquid flow rate adjusting member and / or the second liquid flow rate adjusting member, the two types of liquid can be changed to have a desired mixing ratio, and the two types of liquid can be changed. Even if it changes, the liquid mixture of a desired compounding ratio can be obtained easily.

  In addition, the present invention also stores a main liquid composed of an aqueous sodium hypochlorite solution stored in the apparatus main body, a main container capable of flowing out from the main liquid outflow portion provided in the lower part, and a smaller amount than the main liquid in the inside. In addition, a sub-liquid composed of a pH adjusting liquid for adjusting the PH value of the main liquid can be discharged from a sub-container capable of flowing out from a sub-liquid outflow portion provided in the lower part, and two types of liquids, the main liquid and the sub-liquid, are discharged.

Furthermore, the acidified liquid flow rate adjusting member 81 is inserted into the tube liquid inflow portion 61 in a state of being inserted through the bag stopper member 32 (see an enlarged view of the region X in FIG. 2).

  The acidified liquid flow rate adjusting member 81 has a hollow cross section that is a flow path cross section that allows the acidified liquid 30a sealed in the acidified liquid sealed bag 30 to flow into the liquid guide tube 60 side at a desired flow rate. It is composed of a cylindrical member.

Then, the effect | action which the sterilization liquid production | generation apparatus 1 show | plays based on the Example which produces | generates a sterilization liquid using the sterilization liquid production | generation apparatus 1 mentioned above is demonstrated using FIG.
In this embodiment, it is assumed that the main liquid 10a is stored in the main container 10 with a capacity of 18 liters, and the acidified liquid 30a is stored in the acidified liquid enclosure bag 30 with a capacity of 2 liters. .

  Further, the main liquid flow rate adjusting member 71 has a main liquid outflow restricting hole 73 smaller in diameter than the inner diameter of the liquid guide tube 60, for example, one having φ8.5 mm out of φ8.0 mm to φ9.0 mm and is acidic. For the chemical liquid flow rate adjusting member 81, for example, an inner diameter of φ4 mm out of φ3.5 mm to φ4.5 mm is used.

  In other words, the channel cross section at the main liquid flow rate adjusting member 71 and the channel cross section at the acidified liquid flow rate adjusting member 81 are configured to have a channel cross section ratio of about 4.5: 1.

  In order to insert the acidified liquid flow rate adjusting member 81 into the tube liquid inflow portion 61 of the liquid guide tube 60, heat is applied to the peripheral portion of the tube liquid inflow portion 61 to soften the portion. In this state, the acidified liquid flow rate adjusting member 81 can be easily inserted into and removed from the tube liquid inflow portion 61.

  In order to allow two types of liquid to flow out from the sterilizing liquid generating apparatus 1, first, the two-liquid outflow cock 40 is twisted and the two-liquid outflow cock 40 is opened. Specifically, by rotating the rotary nozzle member 51 with respect to the nozzle body 52, as shown in FIG. 4C, the cock main liquid inflow holes 44b and 54b (the outer cock main liquid inflow hole 44b and the inner cock main The liquid inflow hole 54b) communicates. At the same time, as shown in FIG. 4B, the cock acidifying liquid inflow holes 44a and 54a (the outer cock acidifying liquid inflow hole 44a and the inner cock acidifying liquid inflow hole 54a) communicate with each other.

  Thereby, the main liquid 10a flows out from the main container 10 to the internal space of the two-liquid outflow cock 40 through the main liquid outflow hole 21 and the cock main liquid inflow holes 44b and 54b.

  At this time, in the main container body 11, as the stored main liquid 10a gradually decreases, the pressure in the container increases normally. However, when the lid 17 is lightly closed with respect to the cylindrical protrusion 19, a ventilation gap is secured between the lid 17 and the cylindrical protrusion 19, and the opening 14 is used as an air hole. be able to.

  Therefore, the internal pressure of the main container body 11 does not increase, and the main liquid 10a can flow out of the main container body 11 smoothly.

  Further, when the main liquid 10a passes through the main liquid outflow hole 21, the main liquid 10a passes through the main liquid outflow restriction hole 73 of the main liquid flow rate adjusting member 71 (see FIG. 5). It is possible to flow out to the two-liquid outflow cock 40 side with a desired outflow amount corresponding to the flow path cross section of the restriction hole 73.

  On the other hand, the acidified liquid 30a further flows from the acidified liquid sealed bag 30 through the liquid guide tube 60 to the liquid guide tube mounting pipe 46, and then the tube liquid outflow portion 62 and the cock acidified liquid inflow hole 44a, It flows into the two-liquid outflow cock 40 side through 54a.

  At that time, since the bag body 31 is formed with flexibility, as the acidified liquid 30a flows out, the bag body 31 contracts as a whole and the pressure in the bag body 31 does not increase. The outflow of the liquefying liquid 30a is not inhibited.

  When the acidified liquid 30a flows from the acidified liquid sealed bag 30 into the tube liquid inflow portion 61, the acidified liquid 30a passes through the acidified liquid flow rate adjusting member 81 provided in the tube liquid inflow portion 61 (region in FIG. 2). (See enlarged view of X). For this reason, it can flow out to the two-liquid outflow cock 40 side with the desired outflow amount according to the channel cross section of the acidification liquid flow rate adjustment member 81.

  As described above, the main liquid flows into the two-liquid outflow cock 40 side through the cock main liquid inflow holes 44b and 54b, passes through the main liquid flow path portion 56b without being mixed with the acidified liquid 30a, and flows out from the nozzle side main liquid. It flows out of the hole 55b (see FIG. 5).

  On the other hand, the acidified liquid 30a flows into the two-liquid outflow cock 40 side through the cock acidified liquid inflow holes 44a and 54a, passes through the acidified liquid flow path portion 56a without being mixed with the main liquid 10a, and is acidified on the nozzle side. It flows out from the chemical liquid outflow hole 55a (refer FIG. 5).

The sterilization liquid production | generation apparatus 1 mentioned above can show | play the following various effects.
According to the above configuration, the main liquid 10a and the acidified liquid 30a can be outflowed or stopped at the same time only by the opening / closing operation by the knob 53 provided in the two-liquid outflow cock 40. Unlike the case where the cock attached to the container provided for each type of liquid is opened and closed separately, the opening and closing operation of the cock is easy.

  Furthermore, the main liquid 10a and the acidified liquid 30a can be mixed at a desired mixing ratio because the mixing ratio of the sterilizing liquid is not affected by an error in the timing of opening and closing the cock.

  Further, since the nozzle side main liquid outflow hole 55b and the nozzle side acidified liquid outflow hole 55a are arranged side by side at the lower end of the nozzle body 52, the main liquid 10a and the acidified liquid 30a are arranged side by side. Since it flows out, when it flows down or when it is poured into a container (not shown), it is easy to mix with each other, and a high-quality sterilizing solution mixed homogeneously can be obtained.

  Furthermore, since the flow path is divided by the partition plate 57 or the like so that the two types of liquids do not mix with each other before flowing out from the two-liquid outflow cock 40, unexpectedly two types of liquids are generated in the apparatus main body. Mixing and preventing generation of gas harmful to the human body.

  Furthermore, the sterilizing liquid generating apparatus 1 has a configuration in which the acidified liquid sealed bag 30 is disposed above the main container 10.

  For this reason, compared with the main liquid 10a stored in the main container 10, the acidified liquid 30a stored in the acidified liquid enclosure bag 30 can increase its potential energy.

In other words, by installing the acidified liquid enclosing bag 30 upward, the water pressure (outflow pressure) of the acidified liquid 30a in the tube liquid outflow portion 62 can be increased.
As a result, the acidified liquid 30a stored in the acidified liquid sealed bag 30 flows out in a smaller amount than the main liquid 10a, but the acidified liquid 30a does not flow out and is constant until the outflow is completed. The amount of spillage can be sustained.

  In addition, compared with the case where the acidified solution-filled bag 30 and the main container 10 are arranged side by side, an installation space is not required, and there is an advantage that a mixed solution can be generated even in a narrow place.

  Moreover, the sterilizing liquid production | generation apparatus 1 is the structure which has arrange | positioned the tube liquid outflow part 62 inside the main container 10 as above-mentioned.

  According to the configuration, the liquid guide tube mounting pipe 46 and the main liquid outflow restriction hole 73 can be arranged in the vertical direction in the main liquid outflow hole 21 inside the main container 10. Thereby, the main liquid 10a flowing out from the main liquid outflow restriction hole 73 and the acidified liquid 30a flowing out from the tube liquid outflow portion 62 are arranged to flow into the two-liquid outflow cock 40 in the same inflow direction. (See FIGS. 4A and 4D).

  Therefore, the main liquid 10a and the acidified liquid 30a can be made to flow into the two-liquid outflow cock 40 under the same conditions, and the main liquid 10a and the acidified liquid 30a are discharged from the nozzle side outflow holes 55a and 545b (nozzle side main There is no change in the outflow amount when flowing out from the liquid outflow hole 55b and the nozzle side acidified liquid outflow hole 55a), and the blending ratio of the two types of liquids does not change.

  Furthermore, by disposing almost the entire liquid guide tube 60 inside the main container body 11, the liquid guide tube 60 does not get in the way and can be configured with a clean and good appearance.

  Further, since the internal space of the two-liquid outflow cock 40 can be partitioned into the main liquid flow path section 56b and the acidified liquid flow path section 56a via the partition plate 57, for example, the inside of the two-liquid outflow cock 40 The main liquid 10a and the acidifying liquid are prevented from flowing back into the main container body 11 through the main liquid flow path portion 56b and the main liquid 10a and the acidifying liquid 30a being mixed unexpectedly. 30a can surely flow out from the nozzle side outflow holes 55a and 545b.

  Further, a plurality of main liquid flow rate adjusting members 71 and acidifying liquid flow rate adjusting members 81 are provided, and the main liquid flow rate adjusting members 71 are configured to be interchangeable with each other at the main liquid outflow portion. Are configured to be interchangeable with each other in the tube liquid inflow portion 61.

  With the above configuration, the mixing ratio of the two liquids can be easily changed so as to be a desired mixing ratio, and a mixed liquid having a desired mixing ratio can be obtained even if the types of the two liquids are changed.

  Further, as described above, the flow path cross section at the main liquid flow rate adjusting member 71 and the flow path cross section at the acidified liquid flow rate adjusting member 81 are in the range of about 4 to 5.0: 1. The flow path section ratio is 5: 1.

  Thereby, the main liquid 10a and the acidified liquid 30a can be made to flow out from the two-liquid outflow cock 40 at a desired outflow amount ratio, and sterilized water having excellent bactericidal action containing a large amount of hypochlorous acid is generated. can do. Furthermore, it is possible to obtain a highly safe sterilizing solution that has a PH value within the range of 4 to 7 and does not generate chlorine gas.

(Example)
By the way, the sterilization liquid produced | generated by the sterilization liquid production | generation apparatus 1 can be used as a washing | cleaning liquid for vegetable washing, for example.

  Specifically, for example, a plurality of vegetable cleaning containers (not shown) having a size capable of accommodating vegetables are prepared, and a small amount of the sterilizing liquid generated by the sterilizing liquid generating apparatus 1 is added to each of the plurality of vegetable cleaning containers. A washing liquid for washing vegetables can be produced by pouring and diluting with water stored in a vegetable washing container.

  The sterilizing liquid used for the cleaning liquid for washing vegetables receives the main liquid 10a and the acidifying liquid 30a flowing out from the two-liquid outflow cock 40 from the lower side, poured into the cup until the predetermined amount is reached, and reaches the predetermined amount. By repeating the work of receiving in another cup from the start of the outflow to the end of the outflow, it is finally possible to obtain a plurality of cups.

  In addition, as described above, the mixed liquid in the plurality of subdivided cups can be mixed and used in each of the plurality of vegetable washing containers. The use is not limited, for example, by mixing and using vegetables each time when washing vegetables.

  The sterilizing liquid subdivided for each of the plurality of cups described above is desirably mixed in a desired blending ratio in all the cups.

  Even if the sterilizing liquid that is not mixed at a desired blending ratio is subdivided, it is important that the blending ratio of the acidifying liquid 30a does not increase with respect to the desired blending ratio of the main liquid 10a and the acidifying liquid 30a.

This is because the acid value increases as the proportion of the acidified solution 30a in the mixed solution increases. Specifically, when the PH value is 4.0 to 4.5 or less, toxic gases such as chlorine gas are liberated as shown in the graph of FIG.
In the graph of FIG. 6, the sterilizing liquid is obtained by adding the acidifying liquid 30a to sodium hypochlorite as the main liquid 10a and adjusting the PH value until the PH value is between 4.5 and 6.5. As shown in FIG. Moreover, when the acidification liquid 30a is further added and the PH value becomes 4.0 to 4.5 or less, it is shown that chlorine gas harmful to the human body is generated.

  Under such a premise, in the sterilizing liquid generator 1 of the present embodiment, as described above, the flow path cross section of the main liquid outflow restriction hole 73 and the flow path cross section of the inner diameter of the acidified liquid flow rate adjusting member 81 are The flow path in which the outflow of the acidified liquid 30a from the acidified liquid filled bag 30 is completed earlier than the outflow of the main liquid 10a from the main container 10 according to the volume ratio of the container 10 and the acidified liquid filled bag 30. The cross-sectional ratio is used.

  Specifically, the main liquid 10a and the acidified liquid 30a are stored in the main container 10 and the acidified liquid sealing bag 30 so as to have a volume ratio of 9 (18 liters): 1 (2 liters), respectively. In the sterilizing liquid generating apparatus 1 of the example, as described above, the flow path cross section at the main liquid flow rate adjusting member 71 and the flow path cross section at the acidifying liquid flow rate adjusting member 81 are about 4.5: 1. The road section ratio is used.

  With this configuration, the outflow of the acidified liquid 30a from the acidified liquid enclosure bag 30 is not delayed as compared with the completion of the outflow of the main liquid 10a from the main container 10.

  Therefore, among the mixed liquids in the plurality of cups, the ratio of the alkaline liquid 10a to the mixed liquid in the cup collected immediately before the liquid outflow from the two-liquid outflow cock 40 is completed may increase. However, in any case, the acid value does not become strong, and there is no possibility of generating harmful gases such as chlorine gas, and a safe mixed liquid can be obtained.

  Subsequently, the sterilizing liquid generator 1 is set under the above-described settings of the volume ratio between the main liquid 10a and the acidified liquid 30a and the flow path cross-sectional ratio between the main liquid flow rate adjusting member 71 and the acidified liquid flow rate adjusting member 81. The liquid A and the liquid B were allowed to flow out of the liquid, and a simple experiment was performed to confirm the mixing ratio of the mixed liquid subdivided into a plurality of cups.

  The A liquid is a colorless sample liquid used as a substitute for the main liquid 10a, and the B liquid is colored as a substitute for the acidified liquid 30a, which is colored red so that the mixture with the A liquid can be seen at a glance. This is a sample liquid.

  In this experiment, as shown in FIG. 1 to No. Nine 9 cups are prepared, and two kinds of liquids A liquid 102 and B liquid 103 are made to flow out in order so that the mixed liquid 101 reaches a predetermined amount in 30 seconds, and the outflow is completed from the start of the outflow. Until a total of 4 minutes and 25 seconds (error ± 5 seconds), the mixed solution 101 was collected in all nine cups 100.

The experimental results of this experiment are shown in FIG.
FIG. 8 shows nine cups in which the sterilizing liquid is stored immediately after the spill until the completion of the spill from the left side to the right side.

  In the result of this experiment, no. 1 to No. The mixed liquid in the cup No. 8 (excluding the mixed liquid in the cup installed at the right end of the front view) is all light red and has the same color, and liquid A and liquid B are mixed homogeneously. I found out.

  And No. collected just before completion of experiment. It was found that the liquid mixture in the No. 9 cup (the liquid mixture in the cup installed at the right end of the front view) was substantially colorless and transparent, so that the mixture of the A liquid was darker than the B liquid. .

  As a result, it was proved that the outflow of the B liquid used as a substitute for the acidified liquid 30a was completed before the outflow of the A liquid used as a substitute for the main liquid 10a was completed.

  Therefore, when the chlorinated alkaline aqueous solution as the main liquid 10a and the acidified liquid 30a are mixed using the sterilizing liquid generating apparatus 1, even in the mixed liquid collected in the cup immediately before the completion of the outflow, chlorine gas or the like is used. It was confirmed that there was no risk of harmful gas generation and a safe mixed solution was obtained.
