A cylindrical body 7 hangs down from the provided through hole 6, a filtration brush 8 is removably installed inside the cylindrical body 7, and a partition wall is provided on the side of the filtration chamber 4 at a height that allows water in the filtration chamber 4 to overflow. An outflow chamber 10 is provided through a drain hole 9, and an outflow pipe 11 is provided in the outflow chamber 10, one end of which opens outside the drainage basin main body 1, and the other end of the outflow chamber 101 opens at the bottom of the outflow chamber 10. This is related to.

A conventional drainage basin of this type has a structure as shown in FIG. 1, for example. An inflow chamber 13° having an inlet 12'' is provided on one side of the drainage basin main body 1', a filter basket 14° is provided in the inflow chamber 13', and a settling chamber 2' and an inflow chamber in the center of the drainage basin main body 1' are provided. 13' is partitioned by a partition wall 15' which communicates at the lower part, and partitioned by a partition wall 3' which allows overflow at the upper part between the outflow chamber 10° and the sedimentation chamber 2° on the other side of the drainage basin main body 1°. , an outflow pipe 11' was extended from the outflow chamber 10'.However, in the conventional example, the wastewater flowing in from the inlet 12' enters the inlet chamber 13', and large waste is removed by the filter basket 14'. The sludge and the like is removed and precipitated in the lower part of the settling chamber 2', overflows from the settling chamber 2' to the outflow chamber 10', and flows out from the outflow chamber 10' through the outflow pipe 11'. However, in such a conventional example, large dust is removed in the filter basket 14' and sludge is removed in the settling chamber 2'';
There was a drawback that the oil content was difficult to remove, and the oil content was contained in the wastewater when it was discharged.

The present invention has been made in view of the above points, and its object is to provide a drainage basin in which oil and small dirt can be effectively removed using a filtering brush.

The present invention will be explained in detail below with reference to Examples. Reference numeral 1 denotes a box-shaped drainage basin main body with an open top, and is made of synthetic resin such as FRP, for example. The material of the drainage basin body 1 may be a metal such as stainless steel in addition to synthetic resin. An inflow chamber 13 is provided on one side of the drainage basin main body 1, an inflow port 12 is provided in the inflow chamber 13 through which wastewater flows in from the drainage channel, and a filtration basket 14 is provided in the inflow chamber 13. It is. The filter basket 14 is shaped like a container with an open top and has handles 17 on both sides. The center of the drainage basin main body 1 is a settling chamber 2, and the inflow chamber 13 and the settling chamber 2 are separated by a partition wall 15 that communicates at the lower part. A filtration chamber 4 is provided on the other side of the drainage basin body 1, and a partition wall 3 with a height that allows water from the sedimentation chamber 2 to overflow is provided between the sedimentation chamber 2 and the filtration chamber 4.
There is a partition. A mounting part 16 is provided on the opposite side of the filtration chamber 4 from the partition wall 3 at approximately the same height as the upper end of the partition wall 3, and a blocking plate 5 is mounted so as to span the upper end of the partition wall 3 and the mounting part 16. Then, the upper opening of the filtration chamber 4 is closed.

A rising wall 18 is provided upright on three sides except one side of the cold closing plate 5, and a handle 19 is provided at the upper end of the rising wall 18. A suitable number of through holes 6 are bored in the closing plate 5, and a cylindrical body 7 is suspended from the through holes 6. Such through hole 6 and cylinder body 7
The number may be one or more. The filtration brush 8 has brushes 8b extending radially upward and downward from a vertical rod of a T-shaped bone portion 8a, and the horizontal rod of the bone portion 8a has a hook portion 20. The filtering brush 8 is made of synthetic resin such as nylon, metal, or the like.

This filtering brush 8 is inserted into the cylinder body 7, and the hook is at the part 20.
is hooked onto the edge of the through hole 6. Filtration chamber 4 and outflow chamber 10
is separated by a partition wall 9 having a height that allows water from the filtration chamber 4 to overflow, and the settling chamber 2 and outflow chamber 10 are separated by a partition wall 21 having a height up to the top of the drainage basin body 1. . This outflow chamber 10 is provided with an elbow-shaped outflow pipe 11 through which water in the outflow chamber 10 flows out, and one end of the outflow pipe 11 is connected to the drainage basin main body 1.
It is open to the outside, and the other end of the outflow pipe 11 is open to the lower part of the outflow chamber 10 . Further, a flange 22 is provided around the upper end layer of the drainage basin main body 1, and the peripheral edge of a cover plate 23 is placed on the flange 22, and the upper surface opening of the drainage basin main body 1 is closed by three cover plates 23.
It is blocked.

This cover plate 23 may be one or more pieces, and 24 is the cover plate 2.
This is the handle number 3. Note that a packing material may be interposed between the cover plate 23 and the flange 22 along the flange 22 for odor prevention.

The drainage basin configured as described above is buried in the ground so that the flange 22 is between the ground and the road surface, and the inlet 12 is communicated with the drainage channel of the kitchen etc., and the outflow pipe 11 is communicated with the sewer etc. . When the wastewater flows into the inflow chamber 10 from the inlet 12, large waste particles are first removed by the filter basket 14.

When a large amount of dust accumulates in the filter basket 14, the lid plate 23 is opened and the filter basket 14 is lifted up to remove the dust inside the filter basket 14. The waste water that has entered the inflow chamber 13 and from which dust has been removed in the filter basket 14 flows into the sedimentation chamber 2, and precipitates such as sludge are deposited in the lower part of the sedimentation chamber 2. When a large amount of this sediment accumulates, the lid plate 23 is opened and taken out from above. At this time, if a sediment receiver is provided at the bottom of the precipitation chamber 2, it will be easier to take out the sediment upward. Drainage from which sediment has been removed is sent to bulkhead 3.
It flows into the filtration chamber 4 through the through hole 6 and the cylindrical body 7. When passing through the through holes 6 and the cylindrical body 7, oil and small dust adhere to the filtering brush 8, and the oil and small dust are removed.

When a large amount of oil or small dust adheres to the filtration brush 8, the filtration brush 8 is pulled upward and the filtration application brush 8 is cleaned or replaced with a new one.

At this time, the filtration application brush 8 can be handled even more easily by holding the handle 19 and lifting the closing plate 5 to take it out.

Furthermore, the inside of the filtration chamber 4 can be cleaned by removing the closing plate 5. The waste water in the filtration chamber 4 flows into the outflow chamber 10 over the partition wall 9, and exits from the outflow chamber 10 through the outflow pipe 11. Since the inlet of this outflow pipe 11° is open at the bottom, even if the waste water that flows into the outflow chamber 10 contains oil, it floats upward in the outflow chamber 10, and the oil-containing waste water is removed from the outflow pipe 11. Not done.

As described above, the present invention provides a filtration chamber on the side of the settling chamber in the main body of the drainage basin via a partition wall with a height that allows the water in the settling chamber to overflow.
The upper surface of the filtration chamber is closed with a closing plate, and a cylinder is suspended from a through hole provided in the closing plate, and a filtration brush is removably installed inside the cylinder, so that water overflows from the sedimentation chamber and prevents the blockage. When the waste water flowing onto the board passes through the through holes and the cylinder, oil and small dirt adhere to the filter brush, and the oil and small dirt are effectively removed. In addition, the filtration brush can be removed from the top, making it easy to clean and replace the filtration brush.
Moreover, an outflow chamber is provided on the side of the filtration chamber through a partition wall with a height that allows the water in the filtration chamber to overflow, and one end opens outside the drainage basin body, and the other end on the outflow chamber side opens at the bottom of the outflow chamber. Since an outflow pipe is installed in the outflow chamber, the wastewater that flows into the outflow chamber from the filtration chamber flows out from the bottom of the outflow chamber through the outflow pipe, and even if oil-containing wastewater flows into the outflow chamber, The oil floats to the top of the outflow pipe, and oil-free wastewater is discharged from the drain pipe.
