Abstract

PROBLEM TO BE SOLVED: To facilitate the removal of precipitated oil and fat contents in a grease trap for intercepting the oil in waste water before draining the waste water discharged from a facility for supplying foods or the like to a sewage pipe. SOLUTION: This grease trap comprises a vessel body divided into two or more parts by partitioning plates, a drainage inflow pipe, a basket for removing miscellaneous matters, a trap for extracting clean liquid, and an outflow pipe. The partitioning plates 21 and 22 and a baffle 9 which are the components of the grease tarp are formed into an integral structure, so that the precipitated contaminant can be collected in the removing work of the structure for cleaning.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grease trap for intercepting oil and fat contained in wastewater before discharging the wastewater discharged from a facility for supplying meals to a sewer pipe or the like.

[0002]

2. Description of the Related Art Conventionally, a grease trap as shown in FIG. 5 has been known as a device for collecting oil and fat in waste water. This conventional grease trap has two
The partition plates 21 and 22 are attached, and the inside of the container body 1 is divided into three chambers, that is, a basket chamber A, an oil / fat separation chamber B, and a trap chamber C, and the drainage passes from the inflow pipe 3 to the basket 30. Then, after flowing into the basket chamber A,
As shown by the arrow, it passes through the lower part of the partition plate 21 and the baffle plate 9 into the oil / fat separation chamber B, passes through the lower part of the partition plate 22 and moves to the trap chamber C, and is discharged from the discharge pipe 4 to the external sewer. It is supposed to be. During this time, the oil / fat contained in the wastewater is separated by the principle of spontaneous floating when the wastewater passes through the basket 30, the basket chamber A, or the oil / fat separation chamber B in the container, and is blocked by the partition plates 21 and 22. Only the drainage that does not contain oil and fat is discharged from the discharge pipe 4 from the lower part of the partition plates 21 and 22 through the trap pipe.

[0003]

However, in the conventional grease trap, the contaminants floating / precipitated in the basket chamber A and the oil / fat separation chamber B are cleaned, for example, by scooping once a month. However, there were the following problems. It is very difficult and heavy to clean the suspended and settled pollutants.
(B) In addition, a baffle plate is installed on the bottom of the container, making cleaning difficult.

[0004]

The inventions of claims 1 to 4 are:
In order to achieve the above-mentioned subject, it constituted as follows.

According to the invention of claim 1, the partition plates 21 and 22 and the baffle plate 9 in the container body 1 of the grease trap are connected by the connecting member 7 to form the scum collecting tank 5 having an integral structure. The invention of claims 2 and 3 provides a scum collecting tank 5
The whole or a part of the bottom face portion 8 of is made to have a mesh shape. The mesh member may be provided outside the scum collecting tank 5. In a fourth aspect of the present invention, a mesh bag is provided in the lower part of the collection tank so that the scum can be collected in a disposable bag that is easy to remove and attach. In this way, clean cleaning and maintenance are facilitated.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a vertical sectional view of a grease trap showing an embodiment of the present invention. 1 is the container body,
3 is a drainage inflow pipe, 30 is a basket, 21 and 22 are partition plates for dividing the inside of the container into a basket chamber A, an oil and fat separation chamber B, and a trap chamber C, 6 is a trap body, 4 is a discharge pipe, and 9 is It becomes a baffle and does not change from the conventional configuration.

In this embodiment, in the above structure, the contaminants floating / precipitated in the oil / fat separation chamber B can be collected by pulling up the scum collecting tank 5 as shown in FIG. That is, the partition plates 21 and 22 are slidable along the guides, but the partition plates 21 and 22 and the baffle plate 9 are integrally connected by the connecting member 7. The bottom portion 8 of the scum collecting tank 5 has, for example, a mesh shape,
The mesh is smaller than the mesh passage hole of the basket 30, and the pollutant is collected, but the drainage containing no pollutant can be discharged to the discharge port 4 through the trap body 6.

Further, the scum collecting tank 5 is further provided with a tray 10 capable of receiving contaminants which may flow out when the tank is pulled up.
May be provided. That is, the scum collecting tank 5 is fixed by the connecting member 7 as shown in FIG. 2, but, for example, as shown in FIG. 3, only the partition plate 22 and the baffle plate 9 are integrated, and the connecting portion is , So that it can be freely moved by the connecting member 11. By pulling up a chain, a wire, or the like connected to the baffle plate 9, the baffle plate 9 and the bottom surface portion 8 may be inclined to collect and collect the contaminants accumulated on the bottom surface portion 8 and the like in the tray 10.

The mesh of the bottom surface portion 8 in FIG. 3 may be provided on the entire surface, or the mesh of the bottom surface portion 8 may be partially provided. Furthermore, as shown in FIG. 4, a mesh bag 18 is provided at the center of the bottom surface 8 and hangs down, and scum is collected in this bag 18 and can be removed appropriately. The bag body 18 may be provided as a disposable type. As a result, clean maintenance can be performed and the work can be easily performed.

[0010]

As described above, according to the present invention, at the time of maintenance, at the same time as the work of taking out the scum collecting tank 5 from the container body 1, it is possible to collect the pollutants suspended and settled in the container body 1, and the partition It is not necessary to remove and clean the plates 21 and 22 and the baffle plate 9 individually, and maintenance can be easily performed. Further, since the bottom surface of the container body 1 becomes flat after the collection tank 5 is removed, it is possible to easily remove the remaining pollutants. Due to this, conventional issues (a)
This has the effect of eliminating (b).
