JP3673966B2 - Filtration and precipitation device with initial rainwater separation device and connected water tank - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a filtration settling device with an initial rainwater separation device and a connected water tank.
[Prior art]
Conventionally, many water tanks for effective use of rainwater are installed in the basement of the building or in the ground. In addition, in the case of a sufficient amount of water that can always be used throughout the year, it is difficult to secure a space for installation. (For example, see the public relations of JP 09-067838 A)
[0003]
[Problems to be solved by the invention]
In order to spread the effective use of rainwater in ordinary households, a rainwater utilization device that can store a large amount of rainwater that has become less contaminated even in a narrow space, and that can be easily cleaned inside the device. provide.
[0004]
[Means for Solving the Problems]
(B) In order to store rain water as clean as possible, the present invention provides a device that can be filtered in two stages to remove dust, earth and sand at the beginning of rainfall. In addition, the filtration and precipitation device can be drained and cleaned individually without reducing the amount of water in the water tank.
(B) Since the present invention can store a large amount of rainwater even in a narrow space, it is possible to freely connect a small water tank, and if it is connected using the back of the building or a place where the site is open as a whole, A large amount of rainwater can be stored.
(C) In the present invention, in order to facilitate cleaning of each individual water tank, there is a water inlet at the bottom of the slope so that water can be drained individually, and the water pipe piped at the bottom of the water tank is opened. By doing so, the dirt of each individual can be released without passing through other water storage tanks.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0006]
FIG. 1 is a cross-sectional view of a state in which an initial rainwater separator (4), a filtration sedimentation tank (2), and a water storage tank (3) are connected and water is fed by a water pump (18).
B) Although the initial rain on the roof surface includes dirt and earth on the surface, it flows through the gutter (1) and flows into the initial storm water separator (4) at the bottom of the gutter. The initial rainwater containing garbage, earth and sand, etc., filled in the apparatus is confined inside by the action of the water stop ball (6). Thereafter, the rainwater flowing in enters the filtration / precipitation tank (2) through the water sampling pipe (10).
B) Rainwater that has entered the filtration settling tank (2) from the water collection pipe (10) is removed again by the dust removal net (14), and the lower part of the L-shaped partition plate (12) and the horizontal partition plate (13) It flows into the upper water pipe through the gap. In the process, sediment and the like are settled to remove dirt from the rainwater and flow to the next water storage tank (3) through the water pipe (16). The trash removal net (14) can be removed and cleaned. The sediment and the like accumulated on the bottom surface of the filtration sedimentation tank (2) can be cleaned alone by opening the drain outlet (11) on the inclined bottom surface. Moreover, inflow of a large amount of rainwater or drainage after full water is performed from an overblow (15) above the dust removal net (14).
C) Rainwater flowing from the water pipe (16) is stored in a water storage tank (3) having a water inlet (17) which is provided with an insect- and dust-proof lid (20) and has an inclined bottom surface which also serves as drainage. The water tank (3) can be installed in a small and narrow space, and each water tank can be installed in any number of places or at remote locations by connecting a water pipe (16) and a water inlet (17) that pass below. It can be connected by adjusting the height, effectively using a vacant place, storing a large amount of rainwater, sending it with a water pump (18), and using it for washing toilet water, washing cars, watering the garden, etc. I can do it.
[0007]
FIG. 2 is a sectional view of the initial rainwater separator (4). There is a spherical water stopcock (5) that sinks into the water at the drain outlet below the inside of the device, rainwater that enters from the rain gutter is stored from below, and the floating ball (6) that is inside the surface rises above the water surface. When it is full, the flow from the rain gutter is stopped while trash and earth and sand are trapped by buoyancy. The rainwater after taking in the initial garbage, earth and sand, etc. passes through the water sampling pipe (10) and enters the filtration and sedimentation tank (2). When the rain stops and the interval until the next rain is long, and dust or earth and sand on the roof surface is taken into consideration, the drainage pedal (7) attached to the main body support pipe (9) below the initial rainwater separator main body (4) ) To push up the spherical water stop cock (5) and discharge the rainwater in the initial rainwater separator main body (4) to the drainage basin (8) to prepare for the next rainfall.
[0008]
【The invention's effect】
The present invention is carried out in the form as described above, and has the following effects. (A) It is possible to store clean rainwater by simply removing and precipitating dirt such as dust and earth and sand at the beginning of rainfall.
(B) It is possible to freely connect small water tanks, and a large amount of rainwater can be stored as a whole if they are connected by utilizing the back of the building or a vacant place on the site.
(C) The initial rainwater separation device, the filtration sedimentation tank, and each water storage tank are devised so that water can be drained individually, and have a water inlet at the bottom, and are easy to maintain and clean.

Claims (1)

  This is a device that separates the initial rainwater debris and top sand before the rain falling on the building roof passes through the rain gutter (1) and is stored in the water tank (3). There is a spherical water faucet (5) that sinks in water and a rainwater separator main body (4) that contains a floating ball (6) that floats on the water. An initial rainwater separation device composed of a drainage pedal (7) for pushing and draining and a main body support pipe (9) that supports the weight of the device on the drainage basin (8).
