Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underwater drug addition device for gradually adding drugs to water.

Conventionally, for example, circulating cooling water used to cool buildings has been used to prevent scale, prevent slime generation,
In order to prevent corrosion or the growth of algae, a slowly soluble solid drug is brought into contact with cooling water, and the dissolved drug is gradually added to the cooling water.
As a device for carrying out this, there is a device in which a solid drug is stored in a porous plastic container and the container is floated on the water surface. but,
In devices that are used floating on the water surface, the contact between the solid drug in the device and the cooling water is extremely unstable, and the dissolution rate of the solid drug is sensitively affected by the flow rate of the cooling water, so it is always stable. There was a problem that the solid drug could not be dissolved.

In the present invention, a container containing a solid drug is provided so as to be completely submerged in water, and is configured so that dissolution of the drug is not inhibited even in the settled state.

Hereinafter, embodiments of the present invention will be described based on the drawings.

In FIGS. 1 to 3, a flat box-shaped container 1
consists of a receiver 1a and a lid 1b. The receiver 1a and the lid 1b have completely the same internal structure. A claw 3 is formed on the upper surface of one of the side walls 2 of the receiver 1a, and a recess 4 is formed on the other side wall 2 opposite to that side wall 2. These claws 3 and recesses 4 are formed in the lid body 1b in exactly the same way, and the claws 3 of the receiver 1a are formed in the recesses (not shown) of the lid body 1b, and the claws of the lid body 1b (not shown) are formed in the lid body 1b. (not shown) are respectively snapped into the recesses 4 of the receiver 1a to form an openable and closable container 1.

Inside the receiver 1a, groove-shaped drug accommodating parts 5, 5, . . . are formed by partition walls 6, 6, . . . to accommodate solid drugs formed into tablets.

The container 1 is designed to have a weight that allows it to sink in water regardless of whether it contains a drug. When the container 1 is made of synthetic resin or the like, if the container itself does not have enough weight, a weight is housed in the space 7 formed by the side wall 2 and the partition wall 6 to increase the specific gravity of the container 1 to 1 or more. do.

A plurality of water passage holes 8 of an appropriate size are provided on the walls of the receiver 1a and the lid 1b, which correspond to the upper and lower surfaces of the container 1, to communicate the drug accommodating portion with the outside.

In addition, the receiver 1a and the lid 1b, which correspond to the upper and lower surfaces of the container 1, have legs 9 that protrude toward the outside.
will be established. Note that 10 is a drug, but 11
is a protrusion that connects threads, etc.

What is shown in FIGS. 4 and 5 is another embodiment of the present invention, in which an opening 13 is provided in the drug accommodating portion 12 formed by the partition wall 15, and a space for accommodating a weight. 14 is the same as the previous embodiment except that it surrounds the partition wall 15 and is formed over the entire inner circumference of the side wall.

Although the embodiment of the present invention has the above-described configuration, the shape of the container 1 is not limited to a square, but may be any shape such as a polygon, circle, or oval. In addition, since the receptor 1a and the lid 1b have the same shape, it is convenient because only one mold is required. 1a may be a relatively deep body, and the lid body 1b may be an extremely shallow lid that covers it, or the lid body 1b may be attached to the receiver body 1a so that it can be opened and closed in a hinged manner. .

Furthermore, in the embodiment described above, the water passage hole 8 was provided in the center of the medicine storage part 5 along the row of tablets, but the water passage hole 8 was made slightly smaller so that the medicine could The holes may be bored in two rows at a position away from the center of the storage portion 5 along the direction in which the tablets are lined up. In addition, the water passage hole 8 is not limited to a round hole,
It may be a slit or even a mesh.

Furthermore, in the embodiment described above, no matter which of the receiver 1a and the lid 1b is on the lower side, the water passage holes 8 provided in the receiver 1a and the lid 1b are not blocked by the bottom of the cooling tower pit, etc. In order to prevent this from happening, both the receiver 1a and the lid 1b are provided with four legs 9 protruding outward at the four corners of the outer surface thereof. However, the bottom surface of the receiver 1a having the water passage hole 8 may be raised by providing thick step portions with an appropriate width on both the left and right edges of the receiver 1a (or the lid 1b). good.

In the above explanation, an example was given in which the solid drug is a tablet, but the present invention is not limited to a tablet, but may be in the form of a lump or a granule. The partition wall 6 forming the housing portion may be omitted. In addition, all the drugs dissolve,
In order to pull the empty container 1 to the edge of the pit and take it out, a long thread-like object is connected to the protrusion 11 of the container 1, and the end of the thread is connected to the edge of the pit. It is convenient to provide an indicator such as a label on the end of the thread or on the container 1 to indicate when it was put into the pit.

Since the present invention has the configuration described above,
Even if the container is submerged in water, the legs are located on the side with the water passage hole, so the water passage hole will not be blocked, allowing the appropriate amount of the drug to settle in the designated position and ensuring that the water comes into contact with the drug. This underwater drug addition device dissolves the drug at the desired rate and causes the desired effect to settle in the water, so there is very little influence from the flow conditions of the cooling water, and the drug can be added stably at regular intervals. can be provided.
