Abstract

(57) [Summary] (With correction) [Problem] To prevent outflow of grease in a tank at the time of cleaning in a grease trap installed in a shallow place where the installation depth is not sufficient. A guide plate for guiding a partition plate (6) near one end side provided with a polluted water inlet (2) and the other end provided with an outlet (3) in a longitudinal direction of a container body (1) is fixed in a vertical direction. Thereby, the inside of the container main body is divided into chambers A, B, and C, and a bucket 8 for removing impurities is provided in the chamber A. In the same way, the chamber B and the adjacent chamber C communicate with each other at the bottom portion, and the trap plate 9 for bisecting the room is fixed to the chamber C at a fixed height position on the bottom portion. In addition, in addition to the communication at the bottom portion, a weir plate 11 for overflowing the drainage liquid is provided upright on the bottom surface between the trap plate and the outlet, and a cover plate for covering the trap plate and the weir plate is provided. Is mounted in a sealed manner using a packing material.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a grease strap.

[0002]

[Prior art]

 The grease trap is for separating and removing impurities and oils and fats from sewage and sewage containing impurities and oils and fats, and is usually as shown in FIG.

[0003]

[Problems to be solved by the invention]

 In this case, since the trap tube p is housed in the container, the container itself needs to have a corresponding constant height H, which is not suitable for installation in a place where the height cannot be increased. In order to improve this, the applicant of the present invention has previously proposed an apparatus disclosed in Japanese Utility Model Publication No. 63-22221. The present invention relates to an improvement of this device.

[0004]

[Means for Solving the Problems]

 According to the present invention, the guide plate for guiding the partition plate near one end side provided with the polluted water inflow port and the other end side provided with the outflow port in the length direction of the rectangular container body is vertically arranged. The interior of the container is divided into chambers A, B, and C, and a bucket for removing contaminants is provided in the chamber A. The chamber A and the chamber B are communicated with each other at the bottom to remove oil and fat. The chamber B is floated and separated in the chamber B, and the chamber B and the adjacent chamber C are communicated with each other at the bottom, and a trap plate that divides the chamber into two at a certain height on the bottom. In addition to being fixed and communicating with the bottom part as well, a weir plate for overflowing the drainage liquid on the bottom surface between the trap plate and the outlet is erected at a certain height. It is characterized in that the cover plate that covers the plate is attached in a sealed manner using packing material.

[0005]

FIG. 1 is a sectional view of a grease strap according to the present invention, and FIG. 2 is a plan view of the same. Reference numeral 1 denotes a rectangular container main body, reference numeral 2 denotes a polluted water inlet provided at one end in the longitudinal direction of the container main body, and reference numeral 3 denotes a clarified water outlet provided at the other end thereof. 4a, 4b and 5a, 5b are guide plates provided in the main body in the vicinity of the inlet 2 and the inlet 3, and 6 and 7 are partition plates guided by the guide plates. It is divided into chambers A, B, and C whose ends are relatively narrow and whose center is relatively wide. At this time, the guide plate and the partition plate guided by the guide plate are installed so that the chambers A and B and B and C communicate with each other at the bottom of the container.

The chamber A accommodates the basket 8 and removes impurities contained in the contaminated water flowing from the inflow port 2, and the contaminated water then goes below the partition plate 6. Into the chamber B, in which oils and fats are suspended and separated on the upper surface.

[0007] Since the chamber B has a relatively large area as described above, the oils and fats in the sewage are separated by floating upward while passing through the chamber. Those not to be separated are separated by floating at the front side in the room C. That is, the chamber C is arranged such that the inverted L-shaped trap plate 9 for dividing the room in front and rear like C ₁ and C ₂ is at a constant height position on the bottom surface and communicates with the lower surface portion. It is fixed.

Reference numeral 10 denotes a weir plate erected on the bottom surface between the trap plate 9 and the outflow port 3 on the side of the rear chamber C ₂ which is divided into _two , and the height h of the weir plate 10 is The height is set to be lower than the upper surface t of the plate 9, and the inflow water from below the trap plate 9 overflows and flows out toward the outlet 3.

Although the inside is made visible using a glass plate or the like, the lid plate 12 is attached in a sealed state using the packing 11. In the drawing, reference numeral 13 denotes a bracket used for mounting these components.

[0010] the chamber C is in the present invention there is provided a structure described above in, oils and fats to be still remaining within the chamber C is than made shall be floated to the initial chamber C _1, fats and thus The removed clear water flows under the trap plate 9 between the plate and the weir plate 10, overflows the upper edge of the weir plate 10, and is discharged toward the outlet 3. It becomes something.

[0011]

[Effect of the invention]

The present invention is configured as described above, and a floating chamber for oil and fat is provided in a relatively wide area in the center of a rectangular shape, and a discharge chamber for the clarified liquid is provided at a location roughly divided into two. separating the chamber C ₁ and the chamber C ₂ by the trap plate, with eggplant so attained is sufficient separation of the residual oil and fat at room C _1, and by trapping plate 9 are without a structure fixed to the vessel When the partition plates 6 and 7 are lifted upward from the guide plates 4a, 4b and 5a, 5b for cleaning the inside of the container, the oils and fats adhering in the chambers A and B flow directly from the chamber C to the outlet 3. In other words, the grease that is washed away by the cleaning inside the container by pulling up the partition plates 6 and 7 is received by the trap plate 9 in a floating state. Proposal 6-2222 No. Whereas becomes flowing out from the outlet over the weir plate, in the present invention are those without such problems.

In the device of the present invention, since the lid plate is fixed to the upper edge of the trap plate between the outlet and the outflow port using a packing material, the lid plate has a deodorizing effect. It will be excellent.
