DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net bag for a grease interceptor which can be easily replaced with a new one when a strainer body of the grease interceptor is clogged.

[0002]

2. Description of the Related Art A grease interceptor separates oils and fats from a wastewater containing a large amount of oils and fats discharged from a kitchen or the like, and prevents obstruction of a pipeline caused by adhesion of the fats and oils to a public sewer or a sewer without any trouble. It is intended to be able to drain into public waters, etc., and is also called a grease trap. This grease interceptor is usually provided with a stainless steel strainer a (garbage basket) in the first tank to which the drainage is guided as shown in FIG. 10, and the vegetable waste and other large cooking waste in the drainage are provided by the strainer a. Debris and the like are separated, and the fats and oils b are floated and separated using the difference in specific gravity in the next tank, and only the wastewater excluding the fats and oils is allowed to flow to the water distribution pipe c.

[0003]

In such a conventional grease interceptor, the strainer a can be taken in and out so that the dust accumulated inside is periodically discarded. Is often clogged. Therefore, when the waste of the strainer a is discarded, it is necessary to remove oil stains on the strainer a to eliminate clogging, but it is troublesome to clean and it takes time, so cleaning is neglected. At present, it has been left unplugged or clogged without being washed at all.

[0004] If the strainer is clogged, the flow becomes poor, and the wastewater may overflow from the grease interceptor to the outside or flow backward, so that the waste is drained. If it gets over and enters the oil reservoir, it will remain as it is and will rot, causing odor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and a disposable mesh bag is detachably attached to prevent the strainer from being clogged without washing the strainer. It is an object to provide a dexterous net bag.

[0006]

As a means for technically solving this problem, the present invention is to form a strainer main body provided inside a grease interceptor with a synthetic resin mesh bag. Is a grease interceptor net having a rectangular frame made of synthetic resin attached to the upper open end, a plurality of attachment holes provided in the frame, and a handle provided in the center of the opposite side. Make the bag a gist. Further, the strainer main body provided inside the grease interceptor is formed of a synthetic resin net bag, and the net bag is a grease interceptor net bag provided with a coarse hook along the upper opening end. Make a summary. Further, the strainer body provided inside the grease interceptor is formed of a synthetic resin mesh bag, and the mesh bag is provided with a coarse hook along the upper opening end, and the hook is formed in a bag shape. The gist of the present invention is a grease interceptor mesh bag formed by passing a string in a loop.

[0007]

According to the present invention, since the strainer body provided inside the grease interceptor is a disposable mesh bag, the garbage collected inside is discarded together with the mesh bag, and a new mesh bag is attached instead. , So that clogging can be prevented without cleaning the strainer.

[0008]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a fixing frame, which is formed in a substantially scalloped shape with a rectangular mounting portion 1a and legs 1b mounted at four corners thereof, and a convex portion 1c for fixing the net is provided on the upper surface of the mounting portion 1a. Are provided at intervals, and a handle 1d is provided at the center of the opposite side.

Reference numeral 2 denotes a mesh bag formed of a synthetic resin. A frame 2a made of a synthetic resin is attached to an upper open end of the mesh bag, and a hole fitted into the convex portion 1c of the fixed frame 1 is provided in the frame 2a. A plurality of 2b is provided corresponding to the position of the convex portion 1c, and a handle 2c is provided at the center of the opposite side.
The mesh bag 2 is attached to the fixed frame 1 and used as a disposable strainer body.

Reference numeral 3 denotes a holding member for the mesh bag 2;
a and a presser bar 3 juxtaposed at a certain interval on the lower surface thereof
b on the plate 3a.
c are provided with a plurality of holes 3c. A pair of the press fittings 3 is prepared so as to be attached to the opposite side of the fixed frame 1.

In order to assemble the strainer 4 as shown in FIG. 2 from these constituent members, first, the mesh bag 2 is attached to the fixed frame 1, and the mesh bag 2 is attached to the projection 1 c of the fixed frame 1. Holes 2b may be fitted respectively.

Next, the holding members 3 are attached to the opposite sides of the fixed frame 1 (the side without the handle 1d).
This mounting is performed by fixing the protrusion 3 c of the fixed frame 1 to the hole 3
In this case, the holding rod 3b of the holding metal fitting 3 enters the mesh bag 2 and presses the side wall surface of the metal bag 2 to prevent the mesh bag 2 from floating. The frame 2 a of the mesh bag 2 is pressed from above by the abutment plate 3 a of the holding member 3 and is fixed to the mounting portion 1 a of the fixed frame 1. It is to be noted that the presser fitting 3 may not only be simply dropped into the fixed frame 1 but also be engaged with the convex portion 1c or may be strongly fixed by using an appropriate fixing means.

The strainer 4 assembled in this manner is used by being installed in a grease interceptor 5 as shown in FIG.

When the mesh bag 2 serving as the strainer body is full of cooking debris or the like, the strainer 4 is taken out of the grease interceptor 5 by grasping the handle 1d of the fixed frame 1 and the holding bracket 3 is removed. The net bag 2 is removed from the fixed frame 1 by lifting using the handle 2c, and the net bag 2 is discarded.

Thereafter, a new mesh bag is attached to the fixed frame 1 in the same manner as described above, and the presser fitting 3 is fitted to form a strainer 4, and the strainer 4 is installed in the grease interceptor 5 again. Can be returned to
By repeating this, only the net bag 2 is disposable, and the net bag is always replaced with a new one, so that the net bag is not used in a clogged state. For this reason, the original function as a strainer can be sufficiently exhibited, and cleaning is not required when dumping garbage.

In the above-mentioned embodiment, the method of taking out the entire strainer 4 when the garbage is discarded is adopted.
It is also possible to adopt a method in which only the outside is taken out and replaced. In this case, for example, as shown in FIG. 4, a rectangular mounting portion 6 is fixed to the inner wall of the grease interceptor 5 ', and a convex portion 6a for fixing the net is provided on the mounting portion, and the mesh bag 2 is mounted. Hardware 3
Alternatively, it may be fixed by pressing. That is, a configuration using the mounting portion 6 instead of the fixed frame 1 is adopted. Incidentally, if the fixing frame 1 is fixed in the grease interceptor, it is also possible to carry out the method of exchanging only the mesh bag 2 without using the mounting portion 6.

It is possible not only to dispose the net bag alone but also to use the entire strainer in a disposable manner. However, from the viewpoint of cost, it is required that the net bag be made of an inexpensive material. Will.

FIG. 5 shows still another embodiment, in which a synthetic resin mesh bag 22 is attached to the outside of a fixed frame 21 and attached. Hook part 22a
The hook portion 22a is hooked on a convex portion 21c provided on the mounting portion 21a of the fixing frame 21 so that the mesh bag 22 can be fixed. The handle 21d of the fixed frame 21 is provided inside the fixed frame 21 so as not to be in the way when the net bag 22 is covered.

In this case, there is no need to use a holding member for fixing the mesh bag as in the above embodiment, and it is not necessary to provide a synthetic resin frame to be attached to the open end of the mesh bag. Therefore, the cost can be reduced by reducing the number of parts.

As described above, the fixed frame 21 with the mesh bag 22 attached thereto is used by being installed in the grease interceptor in the same manner as in the above embodiment. For example, as shown in FIG. Attachment part 21a of fixed frame 21 to the attachment part provided
Is completed, the installation is completed, and the mounting portion 21 of the fixed frame 21 is
The upper portion of the mesh bag 22 is sandwiched between the a and the mounting portion of the grease interceptor, and the mesh bag is also in a stable state.

At the time of this installation, the four legs of the fixed frame 21
Since 21b is located in a columnar shape at the four corners inside the mesh bag 22, the lifting of the mesh bag 22 and the narrowing to the center portion are prevented beforehand, so that the installation work can be performed easily and efficiently. Can be done.

Although not shown, the hook 22 of the mesh bag 22 is not shown.
If a is formed in a bag shape and the string is passed in a ring shape, the fixed frame 21 is removed when the accumulated dust is discarded, and the string is pulled when the mesh bag 22 is removed from the fixed frame 21 so that the mesh bag 22 is pulled. Can be closed, and the net bag 22 can be hung as it is and discarded at the disposal point. Hook 22 of net bag 22
Since a has a bag-shaped double structure, the strength is also increased. on the other hand,
A new mesh bag can be attached to the fixed frame 21 and reused.

If the mesh bag 22 is formed larger than the fixing frame 21, it is easy to attach and detach the mesh bag 22 and it is convenient. If the mesh bag 22 is too large and the opening end of the mesh bag is slackened, the opening end is formed. Tighten the pin as much as possible along the fixed frame 21, and overlap the last remaining part with the convex part
If it is fitted to 21c, the slack can be eliminated. It is preferable to fit an appropriate stopper such as an O-ring only at the location of the projection.

[0024]

As described above, according to the present invention,
The strainer body of the grease interceptor was formed with a synthetic resin mesh bag, which was incorporated into the strainer so that it could be disposable. It is sufficient to attach a new mesh bag, so that it is not necessary to clean the strainer and to prevent the strainer from being clogged. Therefore, the original function of the strainer can be sufficiently exerted, and at the same time, it is possible to prevent drainage overflow, backflow phenomenon and odor due to decay caused by clogging, and the practical effect is extremely large.
