DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for capturing and filtering foreign substances such as dust and sand mixed in water for use in guiding water such as rainwater to a water storage tank, and sterilizing the water for use. The present invention relates to a rainwater filtration / antibacterial unit capable of preventing the propagation of algae and various germs.

[0002]

2. Description of the Related Art In recent years, rainwater collected by an eaves gutter of a building is guided to a water storage tank and stored therein, and this rainwater is used as water for washing a toilet or car washing, or watering garden trees and flower beds. Alternatively, they are used as water for emergencies.

[0003]

However, since rainwater collected by the eaves gutter contains impurities such as dust and sand, the rainwater cannot be used without filtering. In addition, when rainwater is stored in a water tank for a long period of time and used as water for an emergency, there is a problem in health and safety that algae and various germs propagate due to organic matter mixed in the rainwater. Was.

The present invention has been made to solve the above-mentioned problems, and can introduce foreign substances such as dust and sand when guiding water such as rainwater to a water storage tank, and can filter the water and sterilize the water to use the water storage tank. It is an object of the present invention to provide a rainwater filtration / antibacterial unit capable of preventing the growth of algae and various germs for a long period of time by guiding the water to the wastewater or sterilizing the water in the water storage tank.

[0005]

The above object is achieved by the following means.

That is, the present invention comprises a bottomed cylindrical outer cylinder, a granular antibacterial agent in the outer cylinder, and an inner bag inserted into the upper part of the outer cylinder. While forming a number of holes smaller than the antibacterial agent, the inner bag is sand, dust,
The present invention proposes a rainwater filtration / antibacterial unit characterized in that dust and the like can be filtered, a gap is formed between the inner bag and the outer cylinder, and the gap is filled with an antibacterial agent.

According to the present invention, when rainwater flowing from the rain gutter passes through the inner bag, fine contaminants such as sand are removed, and the passed rainwater comes into contact with the particulate antibacterial agent in the outer cylinder to cause microorganisms. As a result of the antibacterial treatment of diminished and dead species, not only clean water can be obtained, but also because it is unitized, it can be detachably installed in the water tank, and the inner bag and the antibacterial agent can be taken out together Easy to replace.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an example of a rainwater filtration / antibacterial unit of the present invention, and FIG.
It is sectional drawing which shows the use condition of the rainwater filtration and antibacterial unit of FIG.

As shown in FIGS. 1 and 2, the present invention comprises an outer cylinder 1 having a bottomed cylindrical shape, a particulate antibacterial agent 2 in the outer cylinder, and an inner bag 3 fitted into the upper part of the outer cylinder. A plurality of holes 11 smaller than the granular antibacterial agent 2 are formed in the lower portion of the outer cylinder, and the inner bag 3 is capable of filtering sand, dust, dust, and the like. This is a rainwater filtration / antibacterial unit characterized by forming a gap 4 between the gaps and filling the gap with an antibacterial agent 2.

The size of the hole 11 is preferably in the range of 0.1 to 3.0 mm, and may be set smaller than the size of the antibacterial agent so as not to pass through.

The size of the antibacterial agent 2 is 0.2 to 10 m.
The antibacterial agent 2 has a cylindrical shape with a diameter of 4 m and a length of 4 to 10 mm, and as the antibacterial agent 2, a silver salt or a copper salt mixed in a carrier such as zeolite or plastic to release silver ions or copper ions into the water for use is exemplified. Can be

Examples of the material of the inner bag 4 include cloth, paper, and a sintered porous body of plastic. Depending on the degree of rainwater contamination, it is possible to filter sand, dust, dust and the like. Those having fineness can be used.

When the rainwater filtration / antibacterial unit of the present invention is used, it can be used, for example, by incorporating it into a water storage tank 5 as shown in FIG. The present invention is not limited to this example, and can be incorporated into water tanks of various shapes and sizes.

In the present embodiment, the water storage tank 5 comprises a rectangular tubular main body 51 and a lid 52, and a vertical gutter 6 communicating with an eaves gutter (not shown) penetrates from above the lid 52. Rainwater from the roof (not shown)
Through the upper water collecting chamber 53 in the main body 51.

The upper water collecting chamber 53 is provided with an outer cylinder mounting portion 54 for mounting the outer cylinder 1 having a bottomed cylindrical shape.

An outer flange 55 is provided at an opening edge of the outer cylinder mounting portion 54.
The outer cylinder 1 is detachably attached to the outer cylinder 1 in a watertight engagement.

In this embodiment, the rainwater introduced from the downspout 6 once flows into the water collecting chamber 53, and at this time, large sand and the like are collected at the bottom of the water collecting chamber 53 and removed.

When the amount of rainwater flowing in increases, the water level rises, and the outer flange portion 1 of the outer cylinder 1 watertightly engaged with the outer cylinder mounting portion 54.
2 overflows as indicated by the arrow a, and the inner bag 3
Flows into.

The rainwater from which small sand, dust, dust and the like have been filtered by the inner bag 3 comes into contact with the antibacterial agent 2 filled in the gap 4 between the bottom of the inner bag 3 and the inner bottom of the outer cylinder 1 to perform antibacterial treatment. , Clean water can be obtained and stored in the water storage tank 5.

[0020]

According to the present invention, the rainwater flowing from the rain gutter removes fine impurities such as sand by the inner bag, and contacts the granular antibacterial agent in the outer cylinder to perform antibacterial treatment of microorganisms. Not only is it possible to obtain sufficient water, but also because it is unitized, it can be installed in a water tank so that it can be removed, and the inner bag and the antibacterial agent can be taken out together, making replacement easy.
