[0002]

2. Description of the Related Art It has been practiced in a sewage purification tank to use a medicine bottle for sterilizing sewage and for dissolving a drug for other purposes. A conventional medicine cylinder has a medicine container inside, and is formed in a vertically long cylinder with an opening formed at the lower end side, and is erected with the lower end side submerged in a drain gutter of a disinfection chamber that constitutes a sewage purification tank, The chemicals are dissolved in the sewage flowing from the settling chamber on the upstream side. Since the amount of sewage in a sewage septic tank varies depending on the conditions of use, and there are various types of chemicals having different components, sizes, shapes, etc., for example, Japanese Patent Laid-Open No. 9-150160 stores chemicals. The medicine cylinder is composed of an inner cylinder and an outer cylinder that serves as a support for the inner cylinder.
Various drugs having different solubilities are provided by providing slits on the lower side of the inner cylinder in the circumferential direction with a space therebetween, by providing openings in the outer cylinder having different areas, and by allowing the inner cylinder to move up and down relative to the outer cylinder. Disclosed is a medicine barrel capable of obtaining a stable drug concentration with respect to inflowing sewage even when using.

[0003]

By the way, since the amount of sewage treated in the sewage septic tank varies depending on the situation, it is necessary to prepare various sizes of chemicals to be used, but the prior art medicine can be accommodated. Since the size of the medicine is limited by the inner diameter of the medicine barrel, there is a drawback that various kinds of medicines must be selected and used and the management is troublesome. Also,
The drug that comes into contact with the dirty water absorbs water and expands,
The disadvantage is that the swollen, semi-dissolved drug occludes the opening. Further, since the conventional medicine bottle stores the medicines in a vertically long thin medicine accommodating portion in a state where the medicines are vertically stacked, when the phenomenon that the medicines clog the opening occurs, the dissolution of the medicines is blocked and the uncleaned sewage is generated. There is a drawback that it will be leaked, and there is a drawback that maintenance management for this is required.

The present invention has been made in view of the above-mentioned drawbacks of the prior art. Since sewage is caused to flow from the inner cylinder to the outer cylinder to dissolve the drug in the outer cylinder, the sewage outflow portion is not clogged. The drug can be reliably dissolved, and the contained drug can be evenly dissolved, so there is certainty in use. It can be used for all drugs regardless of their size, so management is easy. It is an object of the present invention to provide a sewage treatment tank medicine bottle that can dissolve a medicine even when a large amount of sewage flows into an inner cylinder and overflows, and that can easily replenish the medicine.

[0005]

[Means for Solving the Problems] The means of the present invention configured to solve the above-mentioned problems is a bottomed outer cylinder having an open top and a purified water outlet hole formed at the lower end side of the outer cylinder. When,
The upper opening serves as a sewage inlet, and an inner cylinder that is erected in the outer cylinder and forms a medicine storage space between the outer cylinder and the inner cylinder is formed at the lower end side of the inner cylinder and communicates with the medicine storage space. Sewage outflow section.

A plurality of sewage outflow portions of the inner cylinder may be circumferentially spaced from each other. With this configuration, even if the medicine is unevenly accommodated in the medicine accommodation space, the medicine can be reliably dissolved.

Further, the opening width of the medicine accommodating space is preferably set so as to accommodate the largest medicine among various medicines having different sizes.

Further, it is preferable that the inner cylinder is configured such that the opening area of the waste water outflow portion can be adjusted to be enlarged or reduced.
