Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a bulkhead member for an interceptor installed in a station, gas station, equipment repair shop, etc.

(Prior Art) As shown in FIG. 5, a grease interceptor 2 for blocking, separating, and collecting oils and fats contained in waste water has, for example, two plates 1 inside a interceptor main body 5.
2 and 13 are installed upright, and the inside of the main body is divided into three chambers.
The waste water that entered from the inlet 9 is passed through the communication passage 3 at the bottom of the partition plate 12 and the partition member 13 while the outflow pipe 11
It is configured to separate and collect the oils and fats contained in each chamber 7 during the flow out from the chamber 7.

This blocker 2 prevents the drainage from flowing out from the outflow pipe 11 in the first chamber 7A where the inlet 9 is located, so that the oil and fat content 8 is not collected much. Therefore, separation of fats and oils is not performed much, and therefore separation and collection of fats and oils is mainly performed in the intermediate second chamber 7B.

(Problem to be solved by the invention) Even if the blocker main body 5 has a large capacity, the three chambers 7
It is divided into A, 7B, and 7C, and the middle chamber 7
B only mainly contributes to the collection of fats and oils, so the collection capacity is small, and the intermediate chamber 7B
If the collected oil and fats are not removed externally, the oil and fats 8 will pass through the communication passage 3 of the partition member 13 and enter the third chamber 7.
It may flow into C.

Since the communication passage 3 is located at the lower part of the partition wall member 13, in the third chamber 7C, the inflow oil and fat flows out from the outflow pipe 11 along with the flow of drainage water before it accumulates on the water surface, and the function of the blocker 2 is disabled. It will lower the Therefore, the amount of oil and fat accumulated in the second chamber 7B is 8%.
It is conceivable to increase the collection capacity of oil and fat by pouring it into the chamber 7C.
Forming a large opening for circulating the fats and oils 8 near the constant water level 6 of No. 3, or lowering the partition member 13 so that the fats and oils 8 flow from above into the third chamber 7C, When a large amount of wastewater flows into the first chamber 7A at once, the oil content 8 in the second chamber 7B rises rapidly and a large amount flows into the third chamber 7C, creating a vortex flow that mixes with the wastewater that has passed through the communication path 3. There is a risk that they will mix.

(Means for Solving the Problems) The present invention can solve the problems of the prior art by providing a hole 4 near the constant water level 6 of the partition member 1 through which the obstruction 8 flows into the adjacent chamber 7C. This is how it was done.

That is, the feature of the specific configuration of the problem solving means in the present invention is that the blockage 8 contained in the waste water flowing into the blocker body 5 from the lower side is separated and stored in the upper part of the blocker body 5. Chamber 7 on one side
A concentrator in which a partition member 1 is erected to divide the chamber 7B and an adjacent chamber 7C leading to the discharge side, and a communication path 3 is formed in the lower part of the partition member 1 to communicate the chamber 7B on one side and the adjacent chamber 7C. , a chamber 7B on one side is located above and near the constant water level 6 of the blocker main body 5.
The point is that a large number of holes 4 are formed to allow the blocker 8 to flow into the adjacent chamber 7C while restricting the flow rate.

(Function) When a large amount of fats and oils (blockers) 8 are collected in the intermediate chamber 7B, the water level 14 lowers and the upper surface 15 of the fats and oils gradually rises above the constant water level 6.
The rising oil and fat 8 flows through the hole 4 in the upper part of the partition member 1.
It flows from above into the adjacent chamber 7C, that is, the chamber where the outflow pipe 11 is located, through which the oil and fat 8 separated in the intermediate chamber 7B accumulates in this adjacent chamber 7C. At this time, even if a large amount of wastewater flows into the intermediate chamber 7B, the oil and fat content 8 in the intermediate chamber 7B is restricted by the many holes 4, and gradually
Flows into C. The oil and fat content 8 rides on the drainage water and passes through the communication path 3.
Since it does not enter the adjacent room 7C from the outflow pipe 1
The intermediate chamber 7B and the adjacent chamber 7C contribute to the collection and retention of the fats and oils 8.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In Figs. 1 to 3, reference numeral 1 denotes a partition wall member of the interceptor 2, which is made of metal or synthetic resin, and has a communication path 3 formed in its lower part, and a large number of holes 4 perforated above the center. A grip portion 18 is also formed at the upper end.

The communication passage 3 is formed by attaching a rectangular tube in an inclined manner to the flat partition member 1, and attaching a large number of corrugated plates inside the rectangular tube so that the space between the corrugated plates becomes a discharge passage. The waste water flows diagonally downward from above the communication path 3. However, the communication path 3 may be a simple opening.

A plurality of holes 4 are formed in two stages, upper and lower, and are spaced apart from each other, and the holes 4a in the lower stage are formed between a constant water level 6 determined when the partition wall member 1 is installed in the main body 5 of the interceptor, and a maximum water level. It is preferably formed so that it is located slightly above. The holes 4 may have one stage or three or more stages, and are not limited to circular holes, but may have various shapes such as ellipses, ellipses, squares, and rectangles.

In FIGS. 3 and 4, one or more partition wall members 1 are provided upright within the main body 5 of the interceptor 2, dividing the interior of the main body 5 into a plurality of chambers 7. In the embodiment, one partition wall member 1 and one conventional partition plate 12 are arranged inside the main body 5 to divide it into three chambers 7A, 7B, and 7C.
The first chamber 7A is provided with a strainer 10 for collecting filth, garbage, etc. from the wastewater flowing in from the inlet 9, and the third chamber 7C is provided with an outflow pipe 11 attached to the main body 5. The mouth is turned downward. Incidentally, the partition member 1 of the present invention may be arranged in place of the partition plate 12.

In the waste water that enters the interceptor 2 from the inlet 9, large filth, garbage, etc. are collected by the strainer 10, and oil and water separation occurs in the first chamber 7A, so some oil and fat is also collected. Drainage from the first chamber 7A is carried out through a flow path 1 between the lower end of the wall plate 12 and the bottom of the main body 5.
6 and flows into the second chamber 7B.

In the second chamber 7B, the communication passage 3 of the partition wall member 1 is located at approximately the same height as the flow passage 16;
Since it is formed by a rectangular tube and slopes downward from above, the drainage from the flow passage 16 rarely flows directly to the communication passage 3, and once a vortex is generated, sufficient oil and water separation is performed. The waste water, which is almost free of oil and fat content, flows into the third chamber 7C through the communication path 3.

In the third chamber 7C, the communication passage 3 and the outlet of the outflow pipe 11 are relatively close, and although the oil-water separation function is lower than that in the second chamber 7B, some separation is performed, and drainage after oil-water separation is carried out. It flows out through the flow pipe 11 to the outside.

In the second chamber 7B, the water surface 14 is initially at a constant water level 6.
However, when the fats and oils 8 are collected and accumulated in the form of a supernatant, the water level gradually decreases from the constant water level 6, and conversely, the upper surface 15 of the fats and oils 8 gradually rises. However, since the holes 4 are formed in the vicinity of the constant water level 6 of the partition member 1, especially at the position above the constant water level 6, the fats and oils 8 do not move upwards from the holes 4 except when the water surface moves up and down when a large amount of wastewater flows in. , flows into the third chamber 7C through the hole 4, and the amounts of oil and fat in the second and third chambers 7B and 7C become approximately equal. Therefore, oil and water separation is mainly performed in the second chamber 7B, but the oil and fat content 8 is divided and retained in the second chamber 7B and third chamber 7C, and the amount of retention is doubled compared to the conventional case.

(Effect of the invention) According to the invention detailed above, there are three communication passages in the lower part.
Since a large number of holes 4 are formed above and near the constant water level 6 of the partition member 1 having The blockages 8 contained in the wastewater flowing into the lower part of the chamber 7B on one side are separated and accumulated in the upper part to form a supernatant, which is then flowed through the numerous holes 4 located above the constant water level 6. It gradually flows into the adjacent chamber 7C while being restricted, and even if a large amount of waste water flows into one chamber 7B at a time, the blockage 8 that accumulates in the one side chamber 7B suddenly flows into the adjacent chamber 7C and creates a vortex. It does not mix with the waste water that has passed through the communication path 3.
