Abstract

PROBLEM TO BE SOLVED: To prevent emission of offensive odors, by providing an opening/ closing member which opens the inflow inlet by the pressure of the stream flowing in an oil trap and closes the inlet by the relief of the stream pressure, at the inflow inlet to the oil trap of a side drain. SOLUTION: A support frame 12 is fitted to the inlet to an oil trap and a receive member 13 provided with a slope 16 inclined downward toward the front side is detachably fitted to both sides 14. And the upper side of an opening/closing member 11 made of an elastic material like rubber is detachably fitted to the upper part of the receive member 13. In this way, effluents flowing down in a side drain, shift the opening/closing member 11 supported by the receive member 13 at the inlet of the oil trap, to the opening position by the pressure and open the member. And then, the effluents enter in the oil trap body and flow through respective chambers and flows out of the discharge outlet. Oil floating on the water level is removed from the upper opening. When the effluent stream stops, the opening of the receive member 13 is closed by the opening/ closing member 11 to prevent emission of offensive odors.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an odor shutter for an oil interceptor.

[0002]

2. Description of the Related Art A conventional oil interceptor of this type is disclosed in Japanese Utility Model Publication No. 63-2541, which is similar to the embodiment of the present invention shown in the drawings. Description will be made with reference to the embodiment. 1
Is a drain main body, 2 is a drain port provided in the tank main body 1, 3 is a baffle which is detachably installed in the tank main body 1, 4 is a slab,
Reference numeral 5 denotes a manhole cover, 6 denotes a side groove, and 7 denotes a grating fitted to the side groove 6. In such a case, the drainage flowing into the tank main body 1 from the gutter 6 moves to the first, second, third chambers 8, 9, and 10 through the baffle 3 as shown by the arrow, and is discharged from the drain port 2. You. The oil contained in the drainage floats on the water surface when the drainage passes through the first, second, third chambers 8, 9, and 10, is blocked by the baffle 3, and is prevented from moving to the next chamber. It will be removed from the upper opening of the main body 1.

[0003]

In the conventional oil interceptor as described above, a bad smell is generated in the tank body 1, and this bad smell flows back to the side groove 6 and escapes from the grating 7 to the outside, thus polluting the environment. There is a problem of doing.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the conventional oil interceptor, to prevent the malodor generated in the tank body 1 from flowing back to the side groove 6, and to reduce the malodor from the grating 7. It is an object of the present invention to provide an odor shutter of an oil interceptor that does not escape to the outside and pollute the environment.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a odor shutter for an oil interceptor, wherein the side groove is provided on the oil interceptor. An opening / closing member that pivotally supports the upper portion to open / close the inlet portion is provided at the inlet portion, the opening / closing member opens the inlet portion by the pressure of the fluid flowing into the oil interceptor, and when this pressure is released, It is characterized in that the inlet is closed.

According to a second aspect of the present invention, the opening / closing member is detachably attached to the upper part of the receiving member detachably attached to the inlet of the side groove to the oil interceptor, and the opening / closing member hangs down. Both sides of the member are characterized by having inclined surfaces that are inclined downward toward the front.

The invention according to claim 3 is characterized in that the opening / closing member is formed of an elastic material which is deformable along a lateral line.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment of the present invention shown in the drawings, the description of the above-mentioned portions will be omitted to avoid duplication. At the entrance of the side groove 6 to the oil interceptor, a support frame 12 having substantially the same shape as the support frame 12 is attached, and a receiving member 13 is detachably fitted to and attached to the support frame 12. It has an inclined surface 16 inclined downward toward the front. The upper side of the opening / closing member 11 is detachably attached to the upper portion of the receiving member 13, and this opening / closing member 11 is formed of an elastic member such as rubber, and can be deformed along a horizontal line, and an opening of the receiving member 13 is formed. The opening is covered and supported so as to open and close.

The wastewater flowing through the side groove 6 in the same manner as the conventional one using the above-mentioned one is received at the inlet of the oil interceptor as shown by the solid line in FIG.
The opening and closing member 11 is supported by being inclined downward toward the front, and is in a closed position for closing the opening of the receiving member 13.
Is moved by the pressure to an opening position which is shown by a chain line in FIG. Through this opening, drainage flows into the tank body 1, moves through the baffle 3 to the first, second, third chambers 8, 9, and 10 and is discharged from the drain port 2 provided in the tank body 1.
The oil contained in the wastewater is as follows:
When passing through 9 and 10, it floats on the water surface and is removed from the upper opening of the tank body 1.

When the inflow of the drainage to the oil interceptor is stopped as described above, the opening / closing member 11 moves to the closing position to close the opening of the receiving member 13 and the malodor generated in the tank body 1 is removed. It prevents backflow into the gutters 6 and prevents bad odors from escaping from the grating 7 and polluting the environment.
When the oil interceptor is filled with drainage, the opening / closing member 11 is moved to the closed position by the pressure to close the opening of the receiving member 13, and the drainage is prevented from flowing back to the side groove 6.

In the above-described embodiment, the opening / closing member 11 is made of an elastic member which is deformable along the lateral line, but it may be made of a rigid member which is not deformable. In that case, the upper side is pivotally supported on the upper part of the receiving member 13.

[0012]

As described above, the present invention relates to an odor shutter for an oil interceptor, and the invention according to claim 1 is such that the upper part is pivotally supported at the entrance of the gutter to the oil interceptor. An opening / closing member for opening / closing the inlet portion is provided, the opening / closing member opens the inlet portion by the pressure of the fluid flowing into the oil interceptor, and when the pressure is released, the inlet portion is closed. There is an effect that the malodor generated in the tank body of the oil interceptor is prevented from flowing back to the gutter so that the malodor does not escape to the outside from the grating and pollute the environment.

According to the second aspect of the present invention, the opening / closing member is attached so that the upper side is detachably attached to the upper portion of the receiving member detachably attached to the inlet of the side groove to the oil interceptor. Both sides of the member have an inclined surface that is inclined downward toward the front, and in the invention according to claim 3, since the opening / closing member is formed of an elastic material that is deformable along a lateral line, these Can be easily attached to and detached from the inlet of the gutter to the oil interceptor, and when the receiving member or the opening / closing member is polluted, these can be cleaned efficiently and completely, and they can be protected from damage. The effect is that if received, it can be easily replaced.
