Description

[Detailed description of the invention] The present invention relates to the structure of a drainage basin that separates and removes garbage and waste oil from wastewater discharged from hotels, restaurants, restaurant kitchens, gas stations, automobile repair shops, etc. A filtration chamber 4 was provided on the side of the precipitation chamber 2 via a partition wall 3 having a height that allows water to overflow from the precipitation chamber 2, and the upper surface of the filtration chamber 4 was closed with a closure plate 5, which was also provided on the closure plate 5. A cylindrical body 7 is suspended from the through hole 6, a filtering brush 8 is removably installed inside the cylindrical body 7, and a partition wall 9 is provided on the side of the filtration chamber 4 with a height that allows the water in the filtration chamber 4 to overflow. An outflow chamber 10 is provided through the drainage basin, and an outflow pipe 11 is provided in the outflow chamber 10, one end of which opens to the outside of the drainage basin main body 1, and the other end on the outflow chamber 10 side opens at the bottom of the outflow chamber 10. This is related.

A conventional drainage basin of this type has a structure as shown in FIG. 1, for example.

An inflow chamber 1 having an inlet 12' on one side of the drainage basin body 1'
3', a filter cage 14' is provided in the inflow chamber 13',
The settling chamber 2' and the inflow chamber 13' in the center of the drainage basin main body 1' are partitioned by a partition wall 15' whose lower part communicates with each other, and the outflow chamber 10' and the settling chamber 2' on the other side of the drainage basin main body 1' are separated. A partition wall 3' that allows flow to overflow is used to partition the chamber 10' from the outflow chamber 10', and an outflow pipe 11' is connected thereto.

However, in the conventional example, the wastewater that flows in from the inlet 12' enters the inlet chamber 13', large wastes are removed by the filter basket 14', and the wastewater flows into the lower part of the settling chamber 2' in the settling chamber 2'. Sludge and the like are precipitated, overflow from the settling chamber 2' into the outflow chamber 10', and flowed out from the outflow chamber 10' via the outflow pipe 11'.

However, in such a conventional example, although large garbage is removed in the filter basket 14' and sludge is removed in the settling chamber 2', the disadvantage is that oil is difficult to remove and is discharged as wastewater. was there.

The present invention has been made in view of the above points, and its purpose is to provide a drainage basin that can effectively remove oil and small dirt using a filter brush.

The present invention will be explained in detail below using examples.

Reference numeral 1 denotes a box-shaped drainage basin body with an open top, and is made of synthetic resin such as F, R, and P, 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.
The inflow chamber 13 has an inlet 12 through which wastewater flows from the drainage channel.
A filter basket 14 is disposed within the inflow chamber 13.

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 body 1 is a settling chamber 2, and the inflow chamber 1
3 and the precipitation chamber 2 are separated by a partition wall 15 that communicates with the lower part.

A filtration chamber 4 is provided on the other side of the drainage basin main body 1, and the sedimentation chamber 2 and the filtration chamber 4 are separated by a partition wall 3 having a height that allows water from the sedimentation chamber 2 to overflow.

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.
The upper opening of the filtration chamber 4 is closed by placing a closing plate 5 so as to extend over the filtration chamber 6.

A rising wall 18 is provided on three sides except for one side of the 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.

The number of such through holes 6 and cylinder bodies 7 may be one or more.

The filtering brush 8 has brushes 8b radially projecting from the vertical rod of the T-shaped bone portion 8a.
The horizontal bar has a hook part 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.

The filtration chamber 4 and the outflow chamber 10 are separated by a partition wall 9 having a height that allows water from the filtration chamber 4 to overflow.
0 is partitioned by a partition wall 21 having a height up to the upper end of the drainage basin body 1.

This outflow chamber 10 is provided with an elbow-shaped outflow pipe 11 through which the water in the outflow chamber 10 flows out. One end of the outflow pipe 11 opens outside the drainage basin body 1, and the other end of the outflow pipe 11 opens to the outside of the drainage basin body 1. It opens at the bottom inside the outflow chamber 10.

Further, a flange 22 is provided around the upper end 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 with three cover plates 23. .

This cover plate 23 may be one piece or a plurality of pieces.

24 is a handle of the cover plate 23. In addition, the cover plate 23 and the flange 2
A packing material may be interposed between the flange 22 and 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 waste water flows into the outflow chamber 10 from the inlet 12, first, large wastes are 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 wastewater that has entered the inflow chamber 13 and from which garbage 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.

The wastewater from which the precipitate has been removed flows over the partition wall 3 onto the closing plate 5, and flows into the filtration chamber 4 through the through hole 6 and the cylinder 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 out upward and the filtration brush 8 is cleaned or replaced with a new one.

At this time, the filtration 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 wastewater flowing into the outflow chamber 10 contains oil, the outflow chamber 11
0, it floats upward and oil-containing wastewater is not discharged from the outflow pipe 11.

As described above, the present invention provides a filtration application chamber on the side of the settling chamber in the main body of the drainage basin through a partition wall with a height that allows water to overflow from the settling chamber, and closes the upper surface of the filtration chamber with a closing plate. The cylindrical body hangs down from the through hole provided in the plate, and the filtration brush is removably installed inside the cylindrical body, so that the waste water that has overflowed from the settling chamber and flowed onto the closing plate is not connected to the through hole and the cylindrical body. When passing through the filtration brush, oil and small dirt adhere to the filtration brush, and the oil and small dirt can be effectively removed. The brushes can be easily cleaned and replaced, and 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 is opened outside the drainage basin body.
In addition, since the outflow chamber is provided with an outflow pipe whose other end on the outflow chamber side opens at the bottom of the outflow chamber, the wastewater flowing into the outflow pipe from the filtration chamber flows out from the bottom of the outflow chamber through the outflow pipe. Therefore, even if oil-containing wastewater flows into the outflow chamber, the oil will float to the top of the outflow pipe, and oil-free wastewater will be discharged from the drainpipe.
