Description

  The present invention comprises a floor slab in which a floor surface forming concrete layer has been placed, an oil separation tank capable of separating oil and fat in the waste water, and a drain trap capable of discharging the waste water separated from the oil and fat. The present invention relates to a grease trap facility in which a trap tank is installed.

The grease trap facility is provided so that drainage in a restaurant kitchen or the like can be discharged to a drain pipe or the like after removing oils and fats mixed in the drainage.
In a conventional grease trap facility, a grease trap unit in which one oil separation tank and one trap tank are integrated is fitted into a through-hole formed in a floor slab (for example, Patent Document 1). , 2 (hereinafter referred to as "first prior art"), one oil separation tank and one trap tank so as to fit in a floor surface forming concrete layer such as a cinder concrete layer placed on the floor slab. The height of the integrated grease trap unit is lowered, and the floor slab is installed without particularly forming a through hole (for example, refer to Patent Document 3: hereinafter referred to as the second prior art).
In addition, when installing one oil separation tank and one trap tank in a through hole formed in the floor slab, the oil separation tank can be used so that the through hole formed in the floor slab can be made smaller. There has also been proposed a grease trap facility in which a trap tank and a trap tank are separately fitted in through holes formed in a floor slab and connected in series by a connecting pipe or the like (see, for example, Patent Document 2; 3 Conventional technology).

Japanese Patent No. 2834066 JP 2000-291125 A (FIGS. 1 to 3) JP 11-236727 A

Since the grease trap equipment of the first and second prior arts has a grease trap unit in which one oil separation tank and one trap tank are integrated, a plurality of oil separation tanks are installed. If necessary, it is necessary to install multiple grease trap units that integrate one oil / fat separation tank and one trap tank, which requires a large floor area and interferes with each other. There is a drawback that it is necessary to be installed so as not to be subjected to the restriction on the arrangement.
In addition, the grease trap facility of the third prior art also has one trap tank corresponding to one or a series of oil separation tanks, and when it is necessary to install a plurality of oil separation tanks, As with the first and second prior arts, a large floor area is required, and it is necessary to install the trap tanks corresponding to each of the oil separation tanks so that they do not interfere with each other. There is.
The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a grease trap facility that does not particularly require a large floor area and is not easily subject to arrangement restrictions when installing a plurality of oil separation tanks. And

  1st characteristic structure of this invention can discharge the waste_water | drain which isolate | separated the said fats and oils and the oil-and-fat separation tank which can isolate | separate the fats and oils in waste_water | drain in the floor slab which has laid the floor-forming concrete layer A grease trap facility provided with a trap tank equipped with a drain trap, wherein the oil / fat separation tank has a plurality of the oil / fat separation tanks in a state in which the waste water from which the oil / fat has been separated can flow separately. The point is that it is connected to the tank.

[Action and effect]
Since a plurality of oil separation tanks are connected in communication with one trap tank, when installing a plurality of oil separation tanks, the oil separation tanks can be dispersed and installed in places where it is easy to collect wastewater. , It can be installed in a place where wastewater from the oil separation tank can easily flow in and drain out, and there is a high degree of freedom in arranging a plurality of oil separation tanks, and there are restrictions on placement. Hateful.
In addition, a plurality of oil separation tanks are connected to one common trap tank in a state where wastewater from which fats and oils are separated can flow separately, so that when installing a plurality of oil separation tanks, Compared to the case where a trap tank is provided for each oil and fat separation tank, the floor area required for installation can be reduced, and installation is less troublesome.

  The 2nd characteristic structure of this invention exists in the point which has installed the said oil-and-fat separation tank in the upper part rather than the said floor slab, and has installed the said trap tank into the said floor slab.

[Action and effect]
Since the plurality of oil separation tanks are installed above the floor slab without particularly forming a through-hole in the floor slab, the strength of the floor slab is not easily lowered, and installation is less troublesome.
In addition, since the trap tank is installed so as to enter the floor slab, it is possible to install a trap tank having a sufficient depth that can easily ensure the water sealing effect.
