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 conventional grease trap equipment, a grease trap unit in which an oil separation tank and a trap tank are integrated is fitted into a through-hole formed in a floor slab (for example, see Patent Documents 1 and 2). (Hereinafter referred to as the first prior art), the height of the grease trap unit is lowered so that it fits in the floor surface forming concrete layer such as a cinder concrete layer placed on the floor slab, and a through hole is formed in the floor slab. (For example, refer to Patent Document 3: hereinafter referred to as second prior art).
There has also been proposed a grease trap facility in which the oil separation tank and the trap tank are not integrated, but are individually fitted in through holes formed in the floor slab and connected by connecting pipes (for example, , See Patent Document 2: hereinafter referred to as third prior art).

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

According to the first prior art, the floor slab cannot be installed unless a large through hole is formed in the floor slab so that the grease trap unit in which the oil separation tank and the trap tank are integrated is fitted. There is a fault that tends to decrease.
According to the second prior art, the floor slab can be installed without forming a through hole in particular, so that the strength of the floor slab is unlikely to decrease, but in order to place the trap tank in the floor surface forming concrete layer, There is a limitation in depth, and there is a drawback that it is difficult to secure a water sealing effect by a drain trap.
According to the third prior art, since it is only necessary to form a relatively small through hole in the floor slab for each of the oil separation tank and the trap tank, compared with the first prior art, the strength of the floor slab is less likely to decrease. Since it is necessary to form a through-hole for each of the oil separation tank and the trap tank in the floor slab, there is a drawback that installation takes time.
The present invention has been made in view of the above circumstances, and it is difficult to reduce the strength of the floor slab, it is difficult to install, and furthermore, a grease trap facility that easily secures the water sealing effect by the drain trap is provided. The purpose is to provide.

  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 in which a trap tank equipped with a drain trap is installed, wherein the oil separation tank is installed above the floor slab, and the trap tank is installed so as to enter the floor slab. In the point.

[Action and effect]
Since the oil / fat separation tank is installed above the floor slab without particularly forming a through-hole in the floor slab, the strength of the floor slab is hardly 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.

  The second characteristic configuration of the present invention is that the oil / fat separation tank and the trap tank are separately installed and connected to each other.

[Action and effect]
Since the oil / fat separation tank and the trap tank are installed separately and connected to each other, the oil / fat separation tank can be installed in a place where wastewater can be easily collected, and the trap tank can easily allow the wastewater from the oil / fat separation tank to flow in. And it can install in the place which discharges | emits drainage easily, and the freedom degree in arrange | positioning an oil-separation tank and a trap tank is high.

  The third characteristic configuration of the present invention resides in that a plurality of the oil separation tanks are individually connected to the common trap tank.

[Action and effect]
Since a plurality of oil separation tanks are connected to the trap tanks individually, the oil separation tanks can be dispersed and installed in a place where wastewater can be easily collected, and the trap tank allows the wastewater from the oil separation tank to flow in. It can be easily installed at a location where drainage is easily discharged, and the degree of freedom in arranging a plurality of oil separation tanks and trap tanks is high.
In addition, since a plurality of oil separation tanks are connected in communication to a common trap tank, installation of a plurality of oil separation tanks is easier than installing a trap tank for each oil separation tank. The required floor area can be reduced, the strength of the floor slab is not easily lowered, and installation is less troublesome.
