Description

[Detailed description of the invention] [Field of industrial application] The device for dissolving and adding solid drugs according to the present invention is capable of dissolving and adding solid drugs that are slowly soluble in tap water, gray water, sewage water, cooling water of cooling towers, and other wastewater. This invention relates to a dissolving/adding device for slowly dissolving solid drugs, which consists of a transparent container that uniformly dissolves the drug, makes it easy to replenish the drug, makes it easy to clean the inside of the device, and makes it easy to check the remaining amount of the drug. It is something.

[Prior art and its problems] Chemicals for water treatment are added for the purpose of preventing scale, preventing corrosion, sterilizing, algaecide, etc.
It is required to maintain the drug concentration in the treated water at a constant level at all times. In particular, the composition of solid slow-dissolving drugs is designed so that they gradually dissolve when they come into contact with running water and maintain their effective concentration. It must be easy to check the remaining medicine, and it must be easy to replenish the medicine and clean the inside. However, none of the conventionally used drug addition devices are equipped with all of these features, and there is a drawback that operation and maintenance cannot be carried out smoothly.

For example, in a device consisting of a hollow container with a bottom and a lid with two water holes, the hollow container has a simple structure and can be molded from transparent synthetic resin, making it easy to check the amount of drug remaining. However, only the drug near the lid comes into contact with running water and elutes, while at the bottom, the drug comes into contact with still water for a long period of time, resulting in a highly concentrated solution that decomposes or precipitates out and is not uniform. There are many problems in terms of efficacy control, additive concentration control, and effective drug use.

In addition, with metal devices that have one water hole each on the top and bottom and one drug replenishment hole in the body, refilling the drug through the small drug replenishment hole is complicated, and cleaning the inside is also difficult. Since the container is opaque, it is difficult to confirm the amount of drug remaining.

On the other hand, in devices where the body is made of a glass cylinder and the lid and bottom are attached separately, it is easy to see the inside of the container, but in order to fix the three components of the cylinder, lid, and bottom, a metal material such as steel is used. The structure is not only complicated and expensive, but also requires a drug replenishment hole to be installed in the lid.
In this case as well, replenishing the medicine through the small medicine replenishment hole is complicated and cleaning the inside is also difficult.

As a result of intensive research into a dissolving/adding device for solid drugs that does not have the above-mentioned drawbacks, the inventor of the present invention has found that:
We have arrived at this idea.

[Means for Solving the Problems and Effects] The device for dissolving and adding solid drugs according to the present invention consists of a container 1 containing a solid drug and a lid 2 having two water holes on the side. A pipe tray 3 with a small hole at the bottom of the hollow container and a pipe 4 connected from a water passage opening 7 at the center of the inside of the lid to the center of the pipe tray 3 so that the liquid passes between the solid drugs. It is characterized in that the lid, container, pipe tray, and pipe can be individually separated.

In the present invention, water enters through the water hole in the lid 2, passes through the water hole 7 at the center inside the lid, passes through the pipe 4, reaches the bottom of the container, and passes through the pores in the pipe tray 3 from the bottom. After passing through the drug layer evenly from the bottom to the top, the drug exits the device through another water hole in the lid, so that no water stoppage occurs and the drug is uniformly dissolved. In addition. In the device of the present invention, there is no difference in the uniform dissolution effect of the drug even if the inlet and outlet of the water hole in the lid are reversed so that the water passes through the drug layer from top to bottom. , can fully achieve the purpose.

This invention requires that there be two water holes on the side of the lid, that the container is made of transparent synthetic resin, and that the lid, container, pipe, and pipe tray can be separated individually. Even if the lid is fixed to the line, the container can be easily removed to replenish medicine or clean the inside, making it much simpler and more efficient than conventional devices. In addition, the transparent synthetic resin container makes it easy to check the remaining amount of drug, and the structure allows water to pass through the perforated plate and come into uniform contact with the solid drug, keeping the elution concentration stable. .

As a result, the present invention can eliminate all of the drawbacks of the prior art, such as variations in drug elution concentration and the complexity of drug replenishment and cleaning operations.

In the present invention, when fixing the container 1 to the lid 2,
It is easy to connect the pipe 4, which has been fitted into the pipe tray 3 at the bottom of the container and stood upright, to the water passage hole 7 located at the center of the inside of the lid. By installing the pipe positioning plate 5, it becomes easier to connect the pipe to the water passage hole 7 located at the center inside the lid. The pipe is connected to a connecting end located at the center of the tray, and the connecting end may be either a simple through hole or a fitting structure as shown in FIG.

Due to the piping, the drug addition device of the present invention does not allow solid drugs to be added to the lid 2 even when installed upside down or horizontally.
It is also a preferred embodiment to fix a perforated plate 6 that spans the inner diameter of the container and has pores to the upper part of the container so as not to tilt toward the container. In this case, first install the pipe tray 3 and pipe 4, and then add the medicine.
The perforated plate plate 6 may be lightly fixed, and then the container may be fixed to the lid 2 while the container is placed upside down or horizontally. Perforated plate 6
The perforated plate plate 6 can also be easily fixed to the cylindrical container by twisting the circumference by about 2 to 3 cm. Perforated plate 6
also serves as the pipe positioning plate 5, so if the perforated plate 6 is used, the pipe positioning plate 5 is unnecessary.

Since the container of the present invention is made of synthetic resin, threaded grooves for fixing parts such as pipes, pipe trays, positioning plates, and perforated plates can be easily formed.

To prevent fine particulate drugs from coming out of the drug layer,
A filter cloth can be installed above the pipe tray 3 and/or below the perforated tray plate 6. The filter cloth is generally pressed against a perforated plate or the like by water pressure and the weight of the solid drug, and is fixed during use. It is also preferable to attach a screw-type drain plug 8 to the bottom of the container to prevent water from spilling when the container is removed.

The drug addition device according to the present invention exhibits particularly excellent effects when it is relatively small. Multiple units can be installed in series or in parallel at various locations on piping as necessary, or they can be easily installed in small-scale facilities such as water pipes for apartment buildings and homes.
