Are mounted inside the box body 1 via engagement projections (not shown) provided at appropriate places. The oil separation plate 6 installed in this way divides the internal space of the basin body 1 into a drainage inflow section F1.
And a secondary space S2 on the side of the drainage outflow portion F2, and an opening 61 at the lower end is formed in the primary space S1.
A detour (indicated by an arrow L1) connecting the secondary space 1 and the secondary space S2 is formed. The oil separating plate 6 is detached from the engaging projection by being pulled upward. Therefore, it can be taken out to the outside through the upper opening 18 of the box body 1 by pulling it upward. The oil separating plate 6 may be fixed to the box body 1 by applying a sealing agent to the abutting portion between the oil separating plate 6 and the body wall 12 or the bottom wall 11 of the box body 1.

In this embodiment, the drainage inflow pipe 100
, Wastewater flowing into the basket 4 once enters the basket 4, and solids such as vegetable waste and hair are collected by the basket 4. The miscellaneous wastewater from which the solids have been separated exits through the water inlet 45 of the basket 4 and flows into the primary space S1. When the water continues to flow into the primary space S1, the water enters the secondary space S2 through the detour L1 formed by the opening 61 of the oil separation plate 6, and the water level gradually rises. When the water level W of the secondary space S2 becomes higher than the lower edge of the outlet of the drainage outflow part F2 (the lowest part 201 of the drainage outflow pipe 200), the water is discharged into the drainage outflow pipe 20.
0, and flows out until the water level of the secondary space S2 falls below the lower edge of the outlet of the drainage outflow portion F2. In a state where the water level of the secondary space S2 is lower than the lower edge of the outlet of the drainage outflow portion F2 and the outflow of water is stopped, the bypass L1 between the primary space S1 and the secondary space S2 is shut off in a water-sealed state. You. Therefore, the backflow of the odor from the sewage main pipe (not shown) connected to the drainage outflow portion F2 is prevented. Further, the oil mixed with the miscellaneous drainage rises to the surface of the water due to a difference in specific gravity with water. For this reason, the oil is shielded by the oil separating plate 6, floated on the water surface on the primary space S1 side and separated, and does not flow into the secondary space S2 side.

The solid matter collected by the basket 4 is processed after the basket 4 removed from the ring-shaped member 7 is pulled up to the outside through the upper opening 18 of the box body 1.

In such a drainage basin for miscellaneous drainage, since the oil separating plate 6 and the like are installed on the opposite side of the annular member 7, the space available for putting the basket 4 into and out of the basin body 1 is reduced. However, since the locking body 73 and the flange body 71 used for the installation of the basket body 4 are provided on the outer periphery of the ring-shaped member 7, the locking body 73 and the flange body 71 are provided on the cage body 4. It does not reduce the space used for access. Therefore, even if the internal space of the basin body 1 is narrow, the basket 4 can be easily taken in and out.

FIG. 5 is a sectional view showing a drainage drainage basin according to an embodiment of the invention according to claims 3 to 6, FIG. 6 is a plan view showing a main part of the drainage basin, and FIG. 5 is a schematic perspective view of a member used in the drainage basin of FIG. 5, and FIG. 8 is an explanatory diagram of the member as viewed from the side.

Here, the vertical length of the recessed opening 46 provided in the basket 4 is as follows. That is, when the flat side wall 43 leans against the flange body 3, the lower end edge 46 a of the opening 46 separates downward from the outer peripheral surface of the short pipe 2 as shown in FIG. A gap C serving as a lifting margin of the basket body 4 is formed and the gap C has a length positioned in a range where the gap C is closed by the second flange portion 32. For this reason, even if the gap C is formed, a situation in which the solid matter collected by the basket 4 flows out from the gap C cannot occur.

When the vertical length of the opening 46 of the basket 4 is determined as described above, when the basket 4 is installed inside the box body 1, the opening 46 is formed in the projecting portion 21 of the short pipe 2. After the fitting, the basket 4 can be lifted to a height at which the handle 42 can be securely locked to the locking body 33. Therefore, the cage 4 can be easily installed. Also, when removing the installed cage 4
If the cage 4 is slightly pulled up using the gap C, the handle 42 can be easily removed from the locking body 33.

The drainage outflow portion F2 is formed by the opening 15 in which the sealing material 17 of the box body 1 is mounted. The connection pipe 5 connected to the end of the drainage inflow pipe (not shown) is inserted into the drainage outflow part F2, or the drainage inflow pipe is directly inserted. The watertightness of the drainage outflow portion F2 is maintained by the seal member 17. Here, the drainage outflow part F2 is provided slightly lower than the drainage inflow part F1 described above, and a sufficient depth is secured in a part lower than the drainage outflow part F2 in the internal space of the cell body 1. ing.

In the drainage basin having the configuration shown in FIG. 5, the same operation as that described with reference to FIG. 1 is exerted.

FIG. 9 shows that the flange body 3 is extended to the left and right sides and the upper and lower parts of the short pipe 2 and the first flanges 31 and 31, respectively.
The locking body 33 and the second flange 32 are shown, and an example is shown in which such a flange 3 is fitted and joined to the short pipe 2. According to this, there is an advantage that the number of parts is smaller than that described in FIG. Note that FIG.

FIG. 11 shows the locking member 33 and the first flange portions 31, 31.
And a case where the short pipe 2 is provided separately from the second flange portion 32. As can be inferred from this case, in order to prevent the basket body from swinging left and right and stabilize the installation state of the basket body, the first flange portions 31 need not necessarily be formed in a flat plate shape. Short tube 2 with rod shape
May protrude on the outer periphery of the. The second flange 3
2 is desirably formed in a flat plate shape having a width capable of closing a gap between the lower end edge of the opening of the basket body and the lower portion of the outer peripheral surface of the short tube 2.

In the embodiment described with reference to FIGS. 5 and 6,
Although the case where the short pipe 2 is fitted in the opening 14 of the drainage inflow portion F1 of the basin main body 1 has been described, there is also a case where the short pipe 2 is not fitted in the opening 14. FIG. 12 shows the case. In the drainage basin of FIG. 1, the end of the drainage inflow pipe 100 is directly fitted into the opening 14 of the drainage inflow portion F1 of the basin body 1, and the drainage inflow pipe 100 protruding into the inside of the basin body 1.
The short tube 2 provided with the locking body 33, the flange body 3 and the rib 34 is fitted to the protruding portion 110. This also makes it possible to install the basket 4 in a stable state as indicated by the imaginary line in FIG.

In FIGS. 1 to 12, the same or corresponding parts are denoted by the same reference numerals.
