DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of dissolving powders and granules in a liquid, and more particularly, to dissolving powders and granules in a short time and easily. The present invention relates to a method and an apparatus for dissolving powders and granules that can safely dissolve even those that require careful handling.

[0002]

2. Description of the Related Art Dissolution of powders and granules is performed in all fields. Particularly in recent years, there are many types that can be dissolved in water for convenience of carrying and the like.

[0003] However, the method of dissolving is a method in which a powder is added to a liquid and then stirred. The method of dissolution differs depending on the properties and temperature of the solvent and the granular material, but the dissolution is promoted by stirring to make the mixing uniform. Melting is an extremely obvious method that is reminiscent of stirring.

[0004] For this reason, when a solution is prepared, the powder and granules are put into the liquid and agitated as a matter of course. However, the powder and granules are difficult to dissolve or require careful handling. Or, it was rather troublesome. That is, it is necessary to stir for a long time and to wear gloves.

[0005] Examples of powdery materials that require careful handling include a chemical for producing acidic water (JP-A-10-81610).
No.). In this method, two types of drugs are used by dissolving them in a predetermined amount of water in a predetermined amount, and the solution has an excellent effect as sterilized water. It should be used in all fields, such as medical institutions, and is in high demand.

[0006] However, one of the two types of chemicals is composed of high-grade powder and requires careful handling in order to generate chlorine gas. Generates chlorine gas. In addition, when it is dissolved in water, it is difficult to dissolve, so it needs to be left for about 3 minutes after pouring it into water, and it must be visually stirred and cry until it is completely melted, which takes time and effort. Also,
As noted above, each drug must not be exposed to water, so care must be taken in storage.

[0007] Although such use is widely required,
There was a difficulty that was difficult to use.

[0008]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a method for dissolving easily, and in particular, for dissolving safely and easily using even those that require careful handling such as chemicals for producing acidic water. A main object is to provide a method for dissolving powder and granules and an apparatus therefor.

Means for this purpose are to supply the granular material to the sent liquid as a solvent in a granular material supply unit, and to pass the liquid supplied with the granular material through a filtration unit to remove undissolved liquid. The method is characterized in that the method is a method of dissolving the powder and granules in which the powders are received, exposed to a flow and dissolved.

[0010] The liquid that has passed through the filtration section is preferably circulated.

Further, it is preferable to use a chemical for generating acidic water which generates acidic water for the powder.

Another means is to provide a reservoir for storing a liquid as a solvent, form a circulation path in the reservoir for circulating the liquid, and supply the powdery or granular material to the liquid on the circulation path. This is characterized in that it is a powder / particle dissolving apparatus in which a fine / granular material supply unit and a filtration unit having fine meshes that allow liquid to pass through but do not pass through the fine particles are arranged in order from the upper side.

It is preferable that the powder supply unit is provided with a metering means for metering and feeding a predetermined amount of powder.

[0014]

According to the above construction, after the liquid as the solvent is sent out, the powder is supplied in the powder supply section, and the liquid is further fed while dissolving the powder to the filtration section. Reach. Then, the undissolved powdery granules are received by the filtration unit, are blocked from passing, and are exposed to the flowing liquid. During this exposure, the granules gradually dissolve and pass through the filtration section.

Since the dissolution is performed in this manner, it is not necessary to stir by hand or machine as in the conventional method, and the dissolution can be performed very easily. Moreover, since foaming does not occur as compared with the case of stirring, it is easy to use regardless of the type and use of the solution.

Further, since the dissolution can be carried out in a closed system, even those requiring caution in handling, such as chemicals for producing acidic water, can be safely dissolved and easily used. For this reason, it is possible to prevent the use of the excellent powders and granules that need to be used and to promote the use thereof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram of a powder / particle dissolving apparatus 1 (hereinafter, referred to as an apparatus) for dissolving a powder / particle.
Can be dissolved as long as it is a granular material, but it is particularly convenient for dissolving a powdery agent for generating weakly acidic functional water (hereinafter, agents A and B). In this embodiment, the medicines A and B are used.
An example of dissolving is shown.

The apparatus 1 comprises a reservoir 2 for storing water C as a solvent, and a pump 3 for pumping water from the reservoir 2.
And a circulation path 4 for returning the pumped water into the storage section 2. On the circulation path 4, there is provided a powder and granule supply section 5 for supplying medicines A and B as powder and granules to flowing water; And a filtration unit 6 that allows liquid to pass through but does not allow undissolved powders (medicines A and B) to pass through in order from the upper side.

The storage section 2 is a section for storing a predetermined amount of water and a section for storing a solution. Since the water C and the chemicals A and B need to be mixed at a predetermined ratio, the storage unit 2 is designed to receive an appropriate amount of water C. Although a scale may be formed, a liquid level detection sensor 7 is also provided as shown in the figure, and if the pump 3 is not driven even when the switch is turned on except when there is a predetermined amount of water, an appropriate solution Is good.

The powder supply section 5 is composed of a container provided with a stopper 5c provided with an inlet 5a and an outlet 5b for water, and measures a predetermined amount of medicine into the container without touching the medicine. An input device 8 (light-weight input means) is provided. The weighing device 8 may be formed in a structure having a hopper 8a at an upper portion and a weighing portion 8b at a lower portion, for example, as shown in FIG. Since there are two types of drugs A and B, the hopper 8a
Since the amounts of the medicines A and B to be charged are different from each other, the sizes of the measuring parts are also different (see FIG. 3).

The measuring section 8b includes a slider 10 inside the main body 9.
And two communication paths 11a and 11b communicating with the hopper 8a are formed in the upper part of the main body 9. The slider 10 has a measuring unit 10a immediately below the communication passages 11a and 11b, and an opening / closing plate 10b arranged below and parallel to the measuring unit 10a with a gap therebetween. The former measuring unit 10a
Are formed vertically through two measuring holes 12a, 12b which communicate with the communication passages 11a, 11b and receive a predetermined amount of medicines A, B, and also have measuring holes 12a, 1 in the opening / closing plate 10b.
One outlet 13 is formed in the portion corresponding to 2b.
The amounts of the medicines A and B are set by the diameters and lengths of the measurement holes 12a and 12b. The measuring unit 10a and the opening / closing plate 10b
A portion of the main body 9 positioned between the measuring unit 10a and the measuring unit 12a is formed with a communication hole 14a, 14b having the same diameter as the blocking hole 9a. ).

That is, in the storage state of the slider 10 shown in FIG. 5, the medicines A and B enter the measuring holes 12a and 12b, but are not discharged because they are blocked by the blocking portion 9a of the main body 9. However, when the slider 10 is pulled toward the user, the measuring holes 12a and 12b overlap the communication holes 14a and 14b formed in the blocking portion 9a of the main body 9 as shown in FIG. Via drug A,
B is discharged. A stopper 15 that regulates a position where the slider 10 is pulled is formed on the upper front side of the main body 9, and a stopper 5 c of the powder supply unit 5 is provided on a lower surface of the slider 10. is there. A switch 16 may be provided on the side of the plug 5c as shown in FIG. 7 to detect whether or not the powder supply unit 5 is attached or detached. In other words, even if the medicine is supplied to the granular material supply unit 5, the safety can be improved by not driving the pump 3 when the stopper 5c is not attached.

As shown in FIG. 8, the filtering section 6 has a structure in which a filter 18 is provided in a case 17 having an inlet 6a and an outlet 6b for water. It is preferable to provide a space between the case 17 and the filter 18 in which the powders A and B can float.

The generation of the weakly acidic functional water in the apparatus 1 configured as described above is performed by firstly adding a predetermined amount of water C to the storage unit 2 and using the metering charging device 8 to supply the predetermined amount of water C to the granular material supply unit 5. Drugs A and B are introduced. Then, the pump 3 may be driven.

The water C pumped out of the reservoir 2 by the operation of the pump 3 passes through the circulation path 4 and enters the granular material supply section 5 and exits together with the medicines A and B. Then, it reaches the filtration unit 6. In the filtration unit 6, only the drugs A and B dissolved in water pass,
Insoluble matter is blocked by the filter 18 and is exposed to flowing water while floating in the space between the case 17 and the filter 18. During this exposure, the medicines A and B are gradually dissolved, and sequentially pass through the filtration unit 6.

The solution that has exited the filtration section 6 returns to the storage section 2 through the circulation path 4. Since water and solution are pumped out of the storage unit 2 by the pump 3 and circulated through the filtration unit 6,
At first, when all the drugs A and B are dissolved even in a thin solution, the concentration becomes a predetermined concentration.

Since the dissolution is performed in this manner, it is not necessary to stir by hand or machine as in the related art, and it is not necessary to wait for a while after adding the drugs A and B. It is extremely easy to dissolve.
Moreover, a large amount of solution can be easily obtained.

Further, a measuring and charging device 8 is provided in the powder and granular material supply section 5 so as not to touch the medicine.
Since it is possible to dissolve in a closed system, even the medicines A and B which require careful handling as described above can be safely dissolved and easily used. Therefore, excellent drugs A and B which are required to be used
You don't have to sleep and can promote usage.

Further, since the metering input device 8 is provided,
It is good to put the purchased medicine in the hopper immediately, so that you do not need to pay special attention to storage,
At the time of use, the metering input device 8 may be operated in a very simple procedure. In addition, although the medicine is supplied to the powder supply unit 5,
Since the medicine is gone by the time the solution is formed, the attaching and detaching operation of the plug 5c is safe.

In addition to the components having the above-described configuration,
It is also possible to adopt a rotary type material which is measured and fed by rotation.
