[0003]

The conventional grease trap is generally as described above. However, when the grease strap is installed, it is necessary to prevent the inflow of mud before the polluted water flows into the grease strap. It is necessary to install a mud receiving basin for sedimenting the mud, and it is necessary to provide an inflow gutter for these. The present invention omits these operations, that is, does not provide a grease strap that can save space, labor and cost for installing a mud receiving trough or a gutter on the market.

[0004]

SUMMARY OF THE INVENTION The present invention divides a rectangular container body into first, second, and third chambers by use of a partition plate which is communicated on a bottom surface in a longitudinal direction thereof. The first room has a mesh basket for separating contaminants in polluted water and a mud separation tank below the mesh basket for separating mud. The second room has the first room for removing contaminants and mud. And the third chamber is provided with a trap tube for discharging the clarified water from which the oil and fat has been separated to the outside of the container. A grease strap is provided above the second chamber and the third chamber, which is provided with a sloped side groove lid plate that is inclined downward from the third chamber toward the second chamber and the first chamber. .

[0005] At this time, the mud separation tank has a cylinder of a fixed height set up in the center of the tank bottom, an umbrella cap is attached above the cylinder, and the inside of the cylinder communicates with the bottom of the first chamber without a bottom. The mud of the sludge flowing down from the upper net basket accumulates on the bottom of the tank, and the waste liquid overflows from the upper edge of the cylinder toward the bottom of the first chamber.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view showing an embodiment of the apparatus of the present invention, FIG. 2 is a cut-away side view showing the center of FIG. 1 cut away, and FIG. 3 shows a mud separation tank used in the apparatus of the present invention. 1A is a plan view, and FIG. In each of the figures, reference numeral 1 denotes a rectangular container body, on which a partition plate 2 and a partition plate 3 are attached on a bottom surface in a longitudinal direction thereof so as to communicate with each other with a constant gap therebetween. A, a second chamber B, and a third chamber C.

[0007] A net basket 4 for separating contaminants in the polluted water is firstly provided in the upper half of the first chamber A, and below the polluted water flowing down through the net basket. In this example, the sludge separation tank 5 is provided with a cylinder 6 having a fixed height at the center of the bottom of the tank, and a sludge separation tank 5 is provided above the cylinder. An umbrella cap body 7 surrounding a fixed height position under a fixed gap is attached, and the inside of the cylinder has no bottom, and is in a state of communicating with the bottom side of the first chamber A.

The mesh basket 4 is provided with a lattice lid on the upper surface, and the sludge separation tank 5 is formed so that the former overlaps with the latter in the latter tank, and a flange piece protrudingly formed at an upper portion of the first chamber. Reference numeral 9 and 10 denote handles attached to the net basket 4 or the sludge separation tank 5, respectively. The net basket and the sludge separation tank 5 can be taken out above the first chamber A. At this time, when pulling the net basket 4 alone, the handle 9 may be lifted upward, and the handle 9 is simply lifted together with the mud separation tank 5 by holding the handle 10.

On the other hand, the second chamber B is a chamber for separating the oil and fat component of the polluted water flowing down to the lower half of the first chamber, and the flowing polluted water passes through the lower edge k of the partition plate 2. Then, the oil and fat are floated upward in the second chamber B, and the clarified water separated from the oil and fat passes through the lower edge k ′ of the partition plate 3 in the chamber. Into the third chamber C, and flows out of the container via the trap 11 in the chamber.

Next, in the present invention, the lid plate 12 of the container body 1 in the above is provided with a side groove. Specifically, the lid plate 12 is provided above the second chamber and the third chamber from the third chamber side. The two chambers are integrally covered, and are formed on a lid plate having an inclination angle θ that is sequentially inclined in a downward state toward the first chamber. At this time,
13a and 13b are handles for lifting. Reference numeral 14 denotes a baffle provided at the bottom of the tank.

The present invention is configured as described above. For example, the polluted water in the kitchen passes through the lid plate 12 formed in the gutter, directly enters the net basket 4 in the first chamber, and then to the sludge separation tank 5. Inflow,
At first, impurities are removed by the net basket 4 and then the sludge separation tank 5
Inside, mud accumulates at the bottom of the tank, and the sewage overflows the upper edge of the cylinder 6 and flows downward through the inside of the cylinder. Thus, the fats and oils of the sewage flowing down into the chamber 1A float and separate while passing through the second chamber B, and the clarified water thereof flows out of the third chamber C through the trap 11. It becomes
This is conventional.

[0012]

The present invention is constructed as described above, and since the lid plate on the upper surface of the container body is formed as a side groove, there is no need to provide a side groove for inflow, and sludge is contained in the container. Since the separation tank is provided, there is no need to separately install a mud receiving basin that is provided in the middle of the conventional gutter, thus contributing to saving space and labor and cost for installing these. It is a great thing to do
Further, the apparatus itself is compact and the whole handling is simple and easy.
