Abstract

PURPOSE:To eliminate the need for chemicals and to efficiently prevent the generation of water-bloom with an ultraviolet sterilizing lamp and to enhance transparency of water by providing a pump for sending water treated with a filter medium and the ultraviolet sterilizing lamp and vertically moving this ultraviolet sterilizing lamp according to the change in the water level of a tank for housing the sterilizing lamp. CONSTITUTION:Water to be treated is introduced into the inside of a filtration vessel 1 through a water passing net 2 and suspended matter included in water is filtrated. The water in the filtration tank 1 is introduced into a tank 7 for housing the sterilizing lamps. Water-bloom is killed by ultraviolet ray emitted from the sterilizing lamps 8 and organic substance included in water is decomposed and removed. Furthermore since the subject purifier is constituted so that the sterilizing lamps 8 are vertically moved, the ultraviolet sterilizing lamps are always positioned in water and water is efficiently treated by ultraviolet rays.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in water purification devices used in garden ponds and the like.

[Conventional technology]

Traditionally, in gardens, park ponds, etc., in order to purify the water quality and further improve the transparency of the water, a sand filter tank has been installed in a part of the waterway to remove debris floating in the water. .

[Problem to be solved by the invention]

However, if the structure is simply provided with a sand filtration tank, it will easily become clogged and lose its filtration function. Especially in the summer, algal blooms occur due to eutrophication, which has the disadvantage of prematurely losing its filtration function.

Conventionally, chemicals are sometimes used to get rid of blue-green algae, but since soot and goldfish are often kept for ornamental purposes in gardens and park ponds, it depends on the type of chemicals or when the chemicals are used in a specified amount. If it exceeds the limit, the carp and goldfish may die.

[Purpose of the invention]

The present invention was invented in view of the above points, and provides a water purification device that efficiently prevents the occurrence of blue-green algae using an ultraviolet germicidal lamp, increases water transparency, and prevents carp and goldfish from dying due to chemicals. The purpose is to

[Means to solve the problem]

The present invention has the following configuration in order to solve the above problems. A filtration tank with a filtration material stored therein, and a sterilization lamp storage tank with an ultraviolet sterilization lamp separate from the filtration tank are provided, and the filtration material adsorbs floating matter contained in the water. After that, it is treated with ultraviolet light using an ultraviolet germicidal lamp in the germicidal lamp storage tank.

In addition, a pump is provided to send water treated with a filter material and an ultraviolet sterilizing lamp, and the ultraviolet sterilizing lamp is configured to move up and down as the water level in the sterilizing lamp storage tank changes.

[Effect]

According to the water purification device described above, suspended matter contained in water is adsorbed by the filter material, and then treated with ultraviolet light using an ultraviolet germicidal lamp to exterminate blue-green algae and decompose and remove organic matter contained in the water.

At this time, the UV germicidal lamp is moved up and down as the water level in the germicidal lamp storage tank changes, so the UV germicidal lamp is constantly in the water, and the water is efficiently treated by the UV light.

〔Example〕

The invention will now be described with reference to FIG. In the figure, 1
1 is a filtration tank having a water passage network 2 on the upper part; Bury it in water circulation paths such as ponds in gardens and parks.

3 is a filter material stored inside the filter tank 1;
For example, it is made of thread and shaped like a ball. Further, a large number of the filter media 3 are stacked in the middle of the filter tank 1. 4
5 is a submersible pump tank constructed adjacent to the filtration tank 1; 6 is a submersible pump housed in the submersible pump tank 5; 7 is adjacent to the submersible pump tank 5. 8 is an ultraviolet sterilizing lamp stored in the sterilizing lamp storage tank 7, and is configured to move up and down as the water level of the sterilizing lamp storage tank 7 changes. be. 9 is a translucent jacket that houses the ultraviolet germicidal lamp 8; 10 is a plate that supports the jacket 9;
11 is a float supported on the lower surface of the plate 10; 12 is a guide supporting a translucent jacket 9 containing an ultraviolet germicidal lamp 8; It consists of 12 lamps. When constructed by storing 12 65-watt germicidal lamps, it is possible to treat about 700 tons of pond water.

13 is a treated water storage tank configured adjacent to the germicidal lamp storage tank, and 14 is a water pump connected to the treated water storage tank 13 for sending the treated water to gardens, park ponds, etc. It is the composition. 15 is a water outlet nozzle for injecting purified water to the filter material 3 during backwashing, and 16 is a diffuser cylinder for injecting air to the filter material 3 during backwashing. It is configured to remove dirt from the material 3. Reference numeral 17 denotes a garbage collection tank from which untreated water from a pond in a garden or park enters the filtration tank 1.

According to this water purification device, water from gardens, park ponds, etc. is passed through the water passage network 2 into the filtration tank 1, where suspended matter is filtered. Furthermore, the water in the filter tank 1 enters the germicidal lamp storage tank 5, where the algal blooms are exterminated by the ultraviolet rays from the germicidal lamp.
Organic matter contained in the water is decomposed and removed, promoting the growth of koi and goldfish.

Further, since the ultraviolet sterilizing lamp is configured to move up and down as the water level in the sterilizing lamp storage tank changes, the ultraviolet sterilizing lamp is constantly located in the water, and the water is efficiently treated by the ultraviolet rays.

〔Effect of the invention〕

As described above, the present invention is a filter medium for a filter tank.

Suspended substances contained in the water are adsorbed and then treated with ultraviolet light using an ultraviolet germicidal lamp.

Therefore, blue-green algae are exterminated and organic matter contained in the water is decomposed and removed, which has the effect of promoting the growth of carp and goldfish in gardens and park ponds.

Further, since the UV germicidal lamp is configured to move up and down as the water level in the germicidal lamp storage tank changes, the UV germicidal lamp is constantly located in the water, and the water is efficiently treated by the UV rays.
