Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a grease trap device.

[0002]

2. Description of the Related Art A grease trap is for separating and removing contaminants and oils and fats from sewage and sewage containing impurities and oils and fats, and the structure thereof is generally as shown in FIG. . Reference numeral 1 denotes a rectangular container main body, and a first chamber A into which contaminated water flows in by using partition plates 2 and 3 which are in a communicating state on the bottom surface in a longitudinal direction thereof, and a second chamber for separating oil and fat. B and a third chamber provided with a trap 4 for taking out the clarified water from which the oils and fats have been separated. In the drawing, 5 is a basket, 6 is a polluted water inflow port, 7 is an outflow port,
8, 8 'and 8 "are lid plates, and 9 and 9' are baffle plates.

[0003]

By the way, in the conventional apparatus, the lid plate 8 'is removed to remove the oil and fat floating to the second chamber B, and the oil is taken into a basket or the like from above using a ladle. Is a time-consuming and time-consuming issue. The present invention seeks to solve the above problems.

[0004]

According to the present invention, in the second chamber for floating the grease of the grease trap, the flat area has substantially the same flat area, and the tank bottom is formed as a double bottom of an upper bottom and a bottom bottom. At the same time, a number of holes and slits are provided differently so that the drilling points do not correspond to both bottoms, and the lower bottom is normally suspended at a certain distance below the upper bottom inside the upper bottom. To allow the oil and fat to float upward through the holes and slits in the lower bottom from the holes and slits in the lower bottom, and raise the lower bottom to the upper bottom position when removing the oil and fat that has floated. Then, a hole and a slit in the upper bottom and the lower bottom are closed to each other and the oil and fat removing tank is configured to be lifted. At this time, the grease removing tank has an angle member attached to a position approximately at an intermediate height in the container of the second chamber, and locks the upper bottom of the grease removing tank. Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0005]

FIG. 1 shows an apparatus according to the present invention.
Is a plan view, B is a side view of A taken along the line X-X, FIG. 2 is a view showing a grease removing tank in the above-described apparatus, wherein A is a plan view,
FIG. 2 is a cross-sectional side view of A of FIG. In this figure, 1 is a container body, 2 and 3 are partition plates for dividing the inside of the container into a first chamber a, a second chamber b, and a third chamber c, 4 is a trap, 5 is a basket, and 6 is polluted. Inlet for water, 7 for outlet, 8,
Although it is the same as the conventional one that 8 'and 8 "are lid plates and 9 is a baffle plate, in the present invention, an oil / fat removal tank 10 is mounted in the second chamber b.

In the present invention, the grease removing tank 10 has the following configuration. In FIG. 2, reference numeral 11 denotes a rectangular tank having a plane area substantially equal to the plane area of the second room, and a tank 11b is an upper bottom of a double bottom and has many holes and slits 12 (see FIG. 2). In the illustrated example, a slit) is formed. Reference numeral 13 denotes a lower bottom which is lifted downward in the upper bottom 11b.
Similarly, holes and slits 14 (slits in the illustrated example) are formed at different positions so as not to correspond to the holes and slits 12 (slits in the illustrated example) provided in b.

Reference numeral 15 denotes a handle which allows the lower bottom 13 to be pulled upward, through which a through hole or a slit formed near both ends in the tank is inserted. It is located. Reference numeral 16 denotes a locking projection provided in the middle of the handle. The locking projection 16 is hooked on the upper bottom 11b so as to prevent the lower bottom 13 from lowering by a certain distance or more. Note that the handle 15 is initially operated by a grease removing operation described later.
To pull the lower bottom 13 into contact with the upper bottom 11b.
1a is located near the same position so that they can be grasped together.

Reference numeral 17 denotes an angle member provided near an approximately intermediate height position of the opposing wall surface in the container body of the second chamber b, which locks the upper bottom 11b of the oil and fat removing tank 10; The tank 10 is held at a fixed height position in the chamber b.

That is, the oil / fat removal tank 10 is constructed as described above and is positioned at about half the height in the second chamber b. In this case, the lower bottom 11b is fixed to the bottom of the tank. Therefore, the contaminated water from which impurities and the like have been removed in the first chamber a and which have entered the second chamber b has a fat and oil content in the lower chamber, which is first removed from the lower bottom plate surface. After passing through the slit 14, the slit 12 on the upper bottom plate surface
And rises to the upper liquid surface of the chamber b.

[0010] The upper liquid surface is layered with the oil component p which floats and separates over time. The cover plate 8 'is removed by an alarm or a lamp display, and the lower bottom 13 is brought into contact with the upper bottom 11b by first holding the handle 15 and pulling it upward, whereby the mutual slits 12 and 14 are formed. Is to be closed.

Next, both the handle 15 and the handle 11a attached to the tank are held and lifted upward by hand, so that the oil or fat floating on the liquid surface in the tank chamber B is raised. The fraction can be stored in the grease removal tank 10 and taken out of the tank. Note that the clarified water from which the fats and oils have been separated as described above enters the third chamber C and is taken out to the outside by the trap 4 in the third chamber C, which is the same as the conventional one.

[0012]

The grease trap device of the present invention is constructed as described above, and the grease p which floats and separates in the second chamber b can be pulled up by holding both the grips 15 and 11a. The entirety of the fats and oils p floating and stacked in the tank 10 can be quickly and accurately taken out to the outside at one time, which greatly contributes to the improvement of work performance.
