As shown in FIG. 1 to FIG. 7, the dust collector of the water intake device of the present invention is made of synthetic resin, and includes a rain gutter 9, a rain water tank 8, and a water intake device described below.
As shown in FIG. 7, the rain gutter 9 is a facility used for transporting a liquid such as rain water to the rain gutter, and in this embodiment, is composed of an eaves gutter 92, a water collector 93, and a gutter 91. . The eaves 92 is arranged in parallel under the eaves of the roof, is arranged so as to receive the rainwater flowing down from the roof, and further, the rainwater (from the eaves 92 ( Drainage) is collected in one place, and finally drained into a rainwater tank through an elbow connected to the water collector 93 and a rod 91 on the vertical pipe.
As shown in FIG. 7, the rainwater tank 8 is a box having a faucet and stores rainwater from the rain gutter 9 described above inside. Note that the user uses the rainwater inside the faucet formed in the rainwater tank 8.
As shown in FIGS. 1 to 6, the water intake device 1 is a device that is installed in the basin 91 and divides the waste water in the basin 91, and includes an adapter chamber 4, a sedimentation chamber 2, It comprises an inlet 5 and an outlet 6, and in this embodiment, it is installed inside the eaves 91 and is piped to the rainwater tank 8 in a horizontally drawn manner.
As shown in FIG. 2, the adapter chamber 4 is a cylindrical member that communicates with the upper and lower sides and is arranged in a watertight manner while dividing the basket 91 into upper and lower parts. It is configured to allow the drainage to flow in and out in eight directions. In the inside, a cylindrical water passage space 42 communicating in the vertical direction is formed at the center, and a spiral spiral portion 41 is integrally formed along the inner peripheral surface and the water passage space 42. The inlet 5 described later is opened on the side surface of the adapter chamber 4 at the lower end of the spiral portion 41. The spiral portion 41 receives drainage falling along the inner periphery from the top of the ridge 91, collects drainage along the spiral, and finally has an inlet 5 configured to be opened at the lower end position of the spiral portion 41. Accordingly, the drainage is drained in the direction of the sedimentation chamber 2. In addition, since the water flow space 42 has a cylindrical shape and the opening is provided on the upper side, when the drainage is sulfided and stored to some extent on the spiral portion of the adapter chamber, the water flow space 42 is provided downstream to overflow from the upper opening. The drainage flows down and drains in the direction of the drainage basin.
The sedimentation chamber 2 includes a separation plate 3, a sedimentation tank 21, and an overflow wall 7. The sedimentation chamber 2 is disposed on the side of the adapter chamber 4 and communicates with the adapter chamber 4 through an inlet 5. Moreover, the sedimentation chamber 2 is configured with a separation plate 3 having a function of precipitating dust in the drainage. As shown in FIGS. 4 and 5, the separation plate 3 is a member having a funnel-shaped inclined surface provided with an opening 31 at the center, and is separated from the waste water below the separation plate 3. A sedimentation tank 21 in which sand and sand settle is formed. As shown in FIG. 3, the sedimentation tank 21 is detachably attached to the sedimentation chamber 2, and both are connected via a watertight member such as packing or O-ring.
The overflow wall 7 is a circular wall surface body located concentrically with the sedimentation chamber 2 and is configured to surround the sedimentation tank 21 and the separation plate 3 by opening the upper end to form a drainage water passage.

As shown in FIG. 2, the inflow port 5 is a tube that communicates from the wall surface of the adapter chamber 4 to the inside of the overflow wall 7 in the sedimentation chamber 2, and the drainage is centrifuged in the overflow wall 7 in the sedimentation chamber 2. The intersection of the tangent on the circumference of the overflow wall 7 and the pipe core of the inflow port 5 is arranged so as to be eccentric so as to cause a swirl flow by force.
In this embodiment, the adapter chamber 4 and the sedimentation chamber 2 are composed of separate members, and both are connected by adhesion or the like.
The outlet 6 is a tube configured on the side surface of the sedimentation chamber 2 (particularly in the direction of the rainwater tank 8), and is a member for discharging the wastewater in the sedimentation chamber 2 to the outside of the water intake device 1.

The dust collector of the water intake device configured as described above has the following drainage flow.
Rainwater that has rained on the roof is received by the eaves jar 92 of the gutter 9 and drained to the gutter 91 through the water collector 93. Since the water intake device 1 is disposed in the middle of the ridge 91, a part of the drainage is drained toward the rainwater tank 8, and the other drainage is drained into a rainwater tank buried in the ground.
The drainage that flows down along the inner peripheral surface of the rod 91 flows down along the spiral portion 41 by the spiral portion 41 of the adapter chamber 4 of the water intake device 1, and the drainage flows into the adapter chamber 4. The wastewater that has reached the inside of the inlet 5 opened at the lower end of 41 is drained out of the adapter chamber 4 by the inlet 5. Thereafter, the drainage is drained into the overflow wall 7 of the sedimentation chamber 2 via the inflow port 5. At this time, since the inlet 5 is configured so that the tangent on the circumference of the overflow wall 7 surface and the tangent on the circumference of the inlet 5 intersect, the drainage from the inlet 5 is overflowed. Since centrifugal force is exerted along the inner circumference of the wall 7 surface, a swirling flow is generated inside the overflow wall 7 surface. Then, since the separation plate 3 is arranged immediately below where the swirl flow is generated, the swirl flow descends along the inclined surface of the separation plate 3 and reaches below the opening 31 of the separation plate 3. At this time, dust and sand in the drainage are deposited below the separation plate 3, that is, in the sedimentation tank 21. Of course, the settled dust does not float upward due to the separation plate 3, and further, the sedimented sand has a larger specific gravity than water, and therefore does not settle and float in the sedimentation tank 21. Thereafter, after the drainage is separated inside the overflow wall 7, the drainage overflows from the upper end of the overflow wall 7 and is discharged from the water intake 1 through the outlet 6 via the sedimentation chamber 2.
The drainage drained from the water intake 1 is finally drained into the rainwater tank 8.
In addition, since the sedimentation tank 21 is detachably attached with screws or the like, the user can easily remove the sedimentation tank 21 from the sedimentation chamber 2.

The dust collector of the water intake device of 2nd Example is used for a rainwater drainage system as shown in FIG.
As shown in FIGS. 7 to 13, the dust collector of the water intake device of the present invention is made of synthetic resin, and includes a rain gutter 9, a rain water tank 8, and a water intake device described below.
As shown in FIG. 7, the rain gutter 9 is equipment used to transport a liquid such as rain water to the rain water gutter, and in this embodiment, the gutter 9 includes an eaves 92, a water collector 93, and a gutter 91. The eaves 92 is arranged in parallel under the eaves of the roof, is arranged so as to receive the rainwater flowing down from the roof, and further, the rainwater (from the eaves 92 ( Drainage) is collected in one place, and finally drained into a rainwater tank through an elbow connected to the water collector 93 and a rod 91 on the vertical pipe.
As shown in FIG. 7, the rainwater tank 8 is a box having a faucet, and is a tank for storing rainwater from the rain gutter 9 described above. Note that the user uses the rainwater inside the faucet formed in the rainwater tank 8.
As shown in FIGS. 8 to 13, the water intake device 1 is a device that is installed in a basin 91 and divides the waste water in the basin 91, and includes an adapter chamber 4, a sedimentation chamber 2, an inflow port. 5 and the outlet 6, and in this embodiment, is installed inside the basket 91 and is piped to the rainwater tank 8 in a horizontally drawn manner.
As shown in FIGS. 10 to 13, the adapter chamber 4 is a cylindrical member that communicates with the upper and lower sides and is arranged in a watertight manner while the basket 91 is divided into upper and lower parts. In this way, the drainage is introduced and branched in the direction of the rainwater tank 8. In the inside, a cylindrical water passage space 42 communicating in the vertical direction is formed at the center, and a spiral spiral portion 41 is integrally formed along the inner peripheral surface and the water passage space 42. The inlet 5 described later is opened on the inner peripheral side surface of the adapter chamber 4 at the lower end of the spiral portion 41. The spiral portion 41 receives drainage falling along the inner periphery from the top of the ridge 91, collects drainage along the spiral, and finally has an inlet 5 configured to be opened at the lower end position of the spiral portion 41. Accordingly, the drainage is drained in the direction of the sedimentation chamber 2. In addition, since the water flow space 42 has a cylindrical shape and the opening is provided on the upper side, when the drainage is sulfided and stored to some extent on the spiral portion of the adapter chamber, the water flow space 42 is provided downstream to overflow from the upper opening. The drainage flows down and drains in the direction of the drainage basin.
The sedimentation chamber 2 includes a separation plate 3, a sedimentation tank 21, and an overflow wall 7. The sedimentation chamber 2 is disposed on the side of the adapter chamber 4 and communicates with the adapter chamber 4 through an inlet 5. Moreover, the sedimentation chamber 2 is configured with a separation plate 3 having a function of precipitating dust in the drainage. As shown in FIG. 11 or FIG. 12, the separation plate 3 is a member having a funnel-shaped inclined surface provided with an opening 31 at the center, and is separated from waste water below the separation plate 3. A sedimentation tank 21 in which sand and sand settle is formed. The sedimentation tank 21 is detachably attached to the sedimentation chamber 2, and both are connected via a watertight member such as packing or O-ring. In addition, an inflow port 5 to be described later is formed on the side surface.
As shown in FIG. 11, the overflow wall 7 is a wall surface of the sedimentation chamber 2 that is positioned in front of the outlet 6, and has an upper end opened to form a drainage water passage.
In this embodiment, the adapter chamber 4 and the sedimentation chamber 2 are integrally formed.
As shown in FIG. 9, the inflow port 5 is a tube that communicates from the wall surface of the adapter chamber 4 to the inside of the sedimentation chamber 2, and in the sedimentation chamber 2, the wastewater is swirled by centrifugal force in the sedimentation chamber 2. The intersection of the tangent on the circumference and the tube core of the inflow port 5 is decentered.
The outlet 6 is a tube configured on the side surface of the sedimentation chamber 2 (particularly in the direction of the rainwater tank 8), and is a tube for discharging the wastewater in the sedimentation chamber 2 to the outside of the water intake device 1. In the present embodiment, in order to increase the drainage flow rate of the water intake device 1 itself, as shown in FIG. 11, the vicinity of the outlet 6 is configured to bulge in the side surface direction.

The dust collector of the water intake device configured as described above has the following drainage flow.
Rainwater that has rained on the roof is received by the eaves jar 92 of the gutter 9 and drained to the gutter 91 through the water collector 93. Since the water intake device 1 is disposed in the middle of the ridge 91, a part of the drainage is drained toward the rainwater tank 8, and the other drainage is drained into a rainwater tank buried in the ground.
The drainage that flows down along the inner peripheral surface of the rod 91 flows down along the spiral portion 41 by the spiral portion 41 of the adapter chamber 4 of the water intake device 1, and the drainage flows into the adapter chamber 4. The wastewater that has reached the inside of the inlet 5 opened at the lower end of 41 is drained out of the adapter chamber 4 by the inlet 5.
Thereafter, the wastewater is drained into the sedimentation chamber 2 via the inflow port 5. At this time, since the inlet 5 is configured so that the tangent on the circumference of the precipitation chamber 2 and the tangent on the circumference of the inlet 5 intersect, the drainage from the inlet 5 is discharged from the precipitation chamber. Since the centrifugal force works along the inner circumferential circle of No. 2, a swirling flow is generated inside the sedimentation chamber 2.
Then, since the separation plate 3 is arranged immediately below where the swirl flow is generated, the swirl flow descends along the inclined surface of the separation plate 3 and reaches below the opening 31 of the separation plate 3. At this time, dust and sand in the drainage are deposited below the separation plate 3, that is, in the sedimentation tank 21. Of course, the settled dust does not float upward due to the separation plate 3, and further, the sedimented sand has a larger specific gravity than water, and therefore does not settle and float in the sedimentation tank 21. Thereafter, after the waste water is separated inside the sedimentation chamber 2, the waste water overflows from the upper end of the overflow wall 7 and is discharged from the water intake 1 through the outlet 6.
The drainage drained from the water intake 1 is finally drained into the rainwater tank 8.
In addition, since the sedimentation tank 21 is detachably attached with screws or the like, the user can easily remove the sedimentation tank 21 from the sedimentation chamber 2.

The dust collecting device of the water intake device of the present invention is not limited to the above-described embodiment, and can be appropriately changed to the extent that it does not exceed the scope of the claims.
For example, although the spiral portion 41 is integrally formed with the adapter chamber 4 in the above embodiment, it may be configured separately.
Moreover, in the said Example, although the shape of the sedimentation chamber 2 and the overflow wall 7 is made into circular shape by the top view, the shape is not ask | required.
Moreover, in the said Example, although the sedimentation tank 21 is made into the shape which can be attached or detached, it does not need to make it especially removable.
Further, the shape of the separation plate 3 in the above embodiment may be a funnel shape having an opening 31 at the center.
Moreover, in the said Example, although the inlet 5 is eccentrically arrange | positioned at the intersection of the tangent on the outer periphery of the sedimentation chamber 2 or the overflow wall 7, and the pipe core of the inlet 5, it is eccentric in this way. Even if the inlet 5 is not generated and is formed at the intersection of the sedimentation chamber 2 or the tube core of the overflow wall 7 and the tube core of the inlet 5, dust and sand in the drainage are below the separation plate 3, that is, settled. Since it settles in the tank 21, there is no particular problem.
