I assume.

Embodiment 1
The solid medicine dissolving apparatus 100 according to Embodiment 1 will be described below with reference to FIGS. 1 to 7.

As shown in FIG. 1, in the present embodiment, the solid medicine dissolving apparatus 100 includes a container part 120, a solid medicine supporting part 21, an introduction channel 11A, and a protrusion 22X as a positional deviation suppressing part, a solid medicine A storage space 11B and a lead-out channel 11C are provided. The container unit 120 includes a container body 2 that constitutes a water tank, and a lid 1 attached to the upper end of the container body 2. The lid 1 is configured to be attached to the container body 2 or removed from the container body 2.

As can be seen from FIGS. 1 and 2, the introduction channel 11A is provided along the outer periphery of the cylindrical pipe 11 extending in the vertical direction, the disk-like flange 12 provided on the upper end of the cylindrical pipe 11, and It is shaped by an annular spacer 13. The introduction channel 11A guides the water to be treated from the outside of the container portion 120 to the lower side of the solid medicine support portion 21. The outlet channel 11C guides the water to be treated, which has come into contact with the at least one solid medicine CA after passing through the at least one communication hole 21A, 21B, to the outside of the container portion 120. The solid medicine storage space 11B is a space where the solid medicine CA is held. At the time of use of the solid medicine dissolving apparatus 100, the water to be treated flows from the introduction flow path 11A into the discharge flow path 11C via the solid medicine storage space 11B.

In the present embodiment, the introduction channel 11A has a T-shaped cross section, but if the treated water can be guided to the lower side of the solid drug support 21, a generally used cylindrical flow It may have any shape, such as the shape of the passage. The outlet channel 11C is a space surrounding the inlet channel 11A having a T-shaped cross section, but any shape may be used as long as the water to be treated can flow down from the upper side of the solid drug support 21. It may be one.

The solid medicine support unit 21 is provided inside the container unit 120 and has at least one communication hole 21A, 21B. In the present embodiment, the at least one communication hole 21A, 21B comprises four inner communication holes 21A and eight outer communication holes 21B. However, the number of the communication holes 21A and 21B may be any number as long as the water to be treated can pass through the solid drug support 21 from the bottom to the top and contact the solid drug CA. In the present embodiment, the introduction flow passage 11A communicates only with at least one communication hole 21A, 21B.

In the present embodiment, the solid drug support 21 supports one solid drug CA, as shown in FIG. However, the solid medicine support unit 21 can also support a plurality of solid medicines CA stacked in the vertical direction. In the present embodiment, the solid drug CA is a chlorine-based solid drug.

As can be seen from FIG. 1 and FIG. 2, the protrusion 22 </ b> X as a positional deviation suppressing portion protrudes upward from the solid medicine support 21 around the solid medicine CA. Therefore, positional deviation of the solid medicine CA is suppressed. As a result, the concentration of the drug dissolved in the water to be treated can suppress the variation.

As shown in FIG. 2, in the present embodiment, the protrusion 22 </ b> X serving as a positional deviation suppressing portion moves the water to be treated to the side so that the water to be treated is not accumulated on the solid drug support 21. It has the notch 22Y which leads. That is, the displacement control unit of the present embodiment is not necessarily formed over the entire circumference of the solid medicine CA. Further, when the water to be treated does not flow into the solid drug dissolving apparatus 100, the damage treated water surface is positioned at a height not to contact the solid drug CA. Therefore, when the water to be treated does not flow, the concentration of the drug dissolved in the water to be treated is prevented from being extremely high partially when the solid drug CA continues to be in contact with the water to be treated. Can.

However, as shown in FIG. 3, even if the projection 22X as the displacement suppression portion is formed of two semi-arc-shaped portions having a notch 22Y between the respective end portions in plan view, Good.

As shown in FIG. 4, the protrusion 22 </ b> X as the positional displacement suppressing portion may have one notch 22 </ b> Y only in a part of the annular protrusion in a plan view.

As shown in FIG. 5, the protrusions 22 </ b> X as the displacement suppressing portion may have a height capable of suppressing displacement of the plurality of solid medicines CA stacked in the vertical direction.

As shown in FIG. 6 and FIG. 7, the positional deviation curb may include three rod-like portions 30 provided at a distance from each other around at least one solid drug CA. Even with this configuration, it is possible to suppress that the concentration of the drug dissolved in the water to be treated is partially extremely high when the at least one disk-shaped solid drug CA continues to be in contact with the water to be treated. it can. According to at least three or more rod-shaped portions 30, particularly when the plurality of disc-shaped solid agents CA are stacked in the vertical direction, the plurality of disc-shaped solid agents CA can be prevented without obstructing the flow of water to be treated. Positional displacement can be effectively suppressed. When the solid drug CA has a disk shape, the number of rod-shaped portions 30 may be three or more in order to suppress the positional deviation of the solid drug CA.

As in the solid drug dissolution apparatus 100 of the present embodiment, if the positional displacement suppression part is a projection 22X having a notch 22Y, the water to be treated does not accumulate on the solid drug support part 21. Therefore, in the present embodiment, the bypass flow passage which directly connects the introduction flow passage 11A and the discharge flow passage 11C described in the second embodiment described later is unnecessary.

In the present embodiment, an example is shown in which the positional displacement suppressing portion is a plurality of protruding portions 22X having notches 22Y between each other. However, if the solid drug dissolving apparatus 100 is always used and the solid drug CA may be kept in contact with the water to be treated, the positional displacement suppressing portion may be an annular ring or a frame having no notch. It may be a peripheral portion having a shape.

Second Embodiment
The solid medicine dissolving apparatus 100 according to the second embodiment will be described below with reference to FIGS. 8 to 10.

As shown in FIGS. 8 and 9, in the present embodiment, the positional deviation suppressing portion is a peripheral edge portion provided to surround at least one solid drug CA all around the periphery of the at least one solid drug CA. 22 That is, the positional deviation suppression unit does not have the notch 22Y described in the first embodiment. However, as can be seen from FIG. 8 and FIG. 9, the solid medicine dissolving apparatus 100 is provided with a bypass channel 110 which directly leads the water to be treated from the introduction channel 11A to the outlet channel 11C. Therefore, instead of the annular spacer 13, a plurality of spacers 13X are provided, and a gap formed between the plurality of spacers 13X constitutes a bypass flow passage 110. The solid medicine dissolving apparatus 100 according to the present embodiment differs from the solid medicine dissolving apparatus 100 according to the first embodiment in the points described above. In the present embodiment, the peripheral portion 22 has an annular shape extending circumferentially, but may have a shape extending along the circumference of a square, a rectangle, or an ellipse.

According to the solid drug dissolving apparatus 100 of the present embodiment, when the water to be treated flows in the solid drug dissolving apparatus 100, the water to be treated passes from the introduction flow passage 11A through the communication holes 22A and 22B. In the process of flowing to the outlet channel 11C, it contacts the solid drug CA. Thereby, solid medicine CA dissolves in treated water. On the other hand, as can be seen from FIGS. 8 and 9, when the water to be treated does not flow in the solid drug dissolving apparatus 100, the water to be treated flows from the introduction channel 11A through the bypass channel 110. It is led to the road 11C. Therefore, when the water to be treated does not flow in the solid drug dissolving apparatus 100, the water surface of the water to be treated is positioned below the solid drug CA. As a result, in the state where the water to be treated is accumulated on the solid medicine support 21, a long time does not elapse. Therefore, it can suppress that the density | concentration of the chemical | medical agent which melt | dissolved in the to-be-processed water becomes extremely high locally partially because solid medicine CA continues to contact to-be-processed water.

However, as shown in FIG. 10, even in the case where the positional displacement suppressing portion (protrusion portion 22X) has the notch 22Y, the solid medicine dissolving apparatus 100 transfers the introduction channel 11A to the outlet channel 11C. You may have the bypass flow path 110 which leads a to-be-treated water directly.

Third Embodiment
The solid medicine dissolving apparatus 100 according to the third embodiment will be described below with reference to FIGS. 11 to 13.

Also in the present embodiment, as shown in FIG. 11, the container unit 120 includes the container body 2 constituting a water tank and the lid 1 attached to the upper end of the container body 2. In the present embodiment, the lid 1 extends downward from the lower surface of the lid 1 as shown in FIG. 11, and the positional deviation of at least one solid drug CA around at least one solid drug CA. Includes a positional deviation limiting unit 40 which limits The solid medicine dissolving apparatus 100 according to the present embodiment differs from the solid medicine dissolving apparatus 100 according to the first or second embodiment in this respect. According to the solid medicine dissolving apparatus 100 of the present embodiment, the movement of the solid medicine CA positioned on the upper side of the plurality of solid medicines CA stacked by the positional deviation limiting unit 40 can be restricted.

In the present embodiment, the distance between the protrusion 22X (or the peripheral edge 22) as the displacement suppression portion and the displacement restriction portion 40 is smaller than the thickness of each of the at least one solid medicine CA. Therefore, at the beginning of use of the solid drug CA, the solid drug CA passes through the gap C between the peripheral edge portion 22 (or the protrusion 22X) as the displacement restraining portion and the displacement displacing portion 40 and is led out 11C. From flowing out to the outside of the container portion 120 is suppressed.

In the present embodiment, the positional deviation limiting unit 40 is three rod-like portions as shown in FIG. However, if the positional deviation limiting unit 40 is provided around the at least one solid medicine CA so as to limit the positional deviation of the at least one solid medicine CA, the cylindrical shape as shown in FIG.
