Description

[Detailed Description of the Invention] The present invention is applicable to the kitchens of hotels, restaurants, and restaurants;
Regarding the structure of the drainage basin that separates and removes garbage and waste oil from wastewater discharged from gas stations, automobile repair shops, etc., the height of the drainage basin is such that the water in the settling chamber 2 can overflow to the side of the settling chamber 2 in the drainage basin main body 1. A filtration chamber 4 is provided through a partition 3, and the upper surface of the filtration chamber 4 is closed with a closing plate 5, and a cylinder 7 is inserted through a through hole 6 provided in the closing plate 5.
hanging down, a filtering brush 8 is removably installed inside the cylinder 7, and an outflow chamber 10 is provided on the side of the filtration chamber 4 via a partition wall 9 having a height that allows the water in the filtration chamber 4 to overflow. This relates to a drainage basin in which an outflow pipe 11 is provided in an 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 a lower part of the outflow chamber 10.

In conventional drainage basins of this type, for example, the first
It was configured as shown in the figure. Drainage basin body 1'
An inflow chamber 13' having an inlet 12' on one side is provided, a filter cage 14' is provided in the inflow chamber 13', and a filter cage 14' is provided in the inflow chamber 13' between the settling chamber 2' and the inflow chamber 13' in the center of the drainage basin body 1'. are partitioned by a partition wall 15' that communicates at the lower part, and partitioned between the outflow chamber 10' on the other side of the drainage basin main body 1' and the sedimentation chamber 2' by a partition wall 3' that allows flow to overflow at the upper part, and the outflow chamber 10' An outflow pipe 11' was drawn out from the outlet. However, in the conventional example, the wastewater flowing in from the inlet 12' enters the inlet chamber 13', large wastes are removed in the filter basket 14', and sludge is deposited in the lower part of the settling chamber 2' in the settling chamber 2'. etc. 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', it is difficult to remove oil, and the waste water contains oil and is discharged. There was a drawback.

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. 1 is a box-shaped drainage basin main body with an open top, for example,
It is made of synthetic resin such as FRP. 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, and an inflow port 1 through which wastewater flows from the drainage channel is provided in the inflow chamber 13.
2, and a filter cage 14 is provided in 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 between the inlet chamber 13 and the settling chamber 2 is a partition wall 1 whose lower part communicates.
It is divided by 5. 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 section 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 section 16. The upper opening of the filtration chamber 4 is closed. A rising wall 18 is provided upright on three sides of the closing plate 5 except for one side, 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 in the cylindrical body 7 may be one or more. The filtering brush 8 has brushes 8b extending radially upward and downward from a vertical bar of a T-shaped bone portion 8a, and a horizontal bar of the bone portion 8a serves as 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 cylindrical body 7, and the hook portion 20 is hooked on the edge of the through hole 6. The filtration chamber 4 and the outflow chamber 10 are separated by a partition wall 9 that is high enough to allow water from the filtration chamber 4 to overflow, and the settling chamber 2 and the outflow chamber 10 are separated by a partition wall 9 that has a height up to the top of the drainage basin body 1. It is partitioned by a partition wall 21. This outflow chamber 10 is provided with an elbow-shaped outflow pipe 11 through which the water in the outflow chamber 10 flows out, and one end of the outflow pipe 11 opens outside the drainage basin main body 1.
The other end opens into the lower part of 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. 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 substantially flush with the ground, 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. It will be done. 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 garbage accumulates in this filter basket 14,
The lid plate 23 is opened and the filter basket 14 is lifted 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 settling chamber 2, and precipitates such as sludge are deposited in the lower part of the settling 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 sediment has been removed flows over the partition wall 3 onto the blocking plate 5 and through the through holes 6.
and flows into the filtration chamber 4 via 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 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 waste water that flows into the outflow pipe 10 contains oil, it floats upward in the outflow chamber 10, and the waste water containing oil is not removed from the outflow pipe 11. .

As described above, the present invention provides a filtration chamber on the side of the settling chamber in the drainage basin main body via 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 is suspended from the through hole provided in the
Since the filtration brush is removably installed inside the cylinder, when the wastewater that has overflowed from the settling chamber and flowed onto the blockage plate passes through the through hole and the cylinder, the filtration brush is free from oil and small particles. It is a device to which dirt adheres, and oil and small dirt can be effectively removed, and the filtration brush can be pulled upwards, making it easy to clean and replace the filtration brush. In addition, an outflow chamber is provided on the side of the filtration chamber through a partition wall with a height that allows water to overflow from the filtration chamber, one end of which opens outside the drainage basin body, and the other end on the outflow chamber side located at the bottom of the outflow chamber. Since an openable outflow pipe is provided 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. However, the oil will float to the top of the outflow pipe, and oil-free wastewater will be discharged from the drain pipe.
