DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin interceptor for drainage equipment, that is, a synthetic resin reservoir.

[0002]

2. Description of the Related Art In general, drainage facilities include a so-called interceptor, which is a harmful / hazardous substance contained in wastewater.
It is an apparatus that can separate and collect an undesired substance or a reusable substance while preventing the substance from flowing down, and drain only the remaining water liquid by gravity.

[0003] The performance of such an interceptor generally does not completely intercept the substance in the wastewater,
It is said that it is sufficient to have the ability to intercept as much as possible, and it is said that many interceptors have a trapping function in addition to this intercepting ability.

The interceptor is a dedicated device such as a grease interceptor, an oil interceptor, a sand interceptor or the like, depending on the kind of the substance to be intercepted.

[0005] Further, various types of this particular dedicated interceptor are known. For example, as an oil interceptor (also referred to as an oil or fat interception device or an oil prevention device), a device using a box trap, a device combined with a mud sump, a device using a ceramic tube, and the like are known.

The oil interceptor using the box trap is as shown in FIG.

That is, an inflow pipe 51 and an outflow pipe 52 face a bottomed quadrangular concrete reservoir 50, and a box trap 53 is provided at an inlet of the outflow pipe 52. When the wastewater mixed with oils and fats flows into the reservoir 50 from the oils and fats 50, the oils and fats float and separate, and only the wastewater flows down from the lower entrance of the box trap 53 to the outflow pipe 52.
The structure is such that the odor on the downstream side does not flow back to the reservoir 50.

In such a concrete reservoir 50, the box trap 53 is detachably mounted so as not to hinder the cleaning of the inside of the box, and to facilitate the cleaning and removal of, for example, oils and fats or earth and sand. , Actual fairness 1-418
No. 32) is known.

However, as shown in FIG. 7 and the proposed concrete reservoir, the inflow pipe 51 and the outflow pipe 52 are made of PVC, as if they were made of ordinary small concrete but were replaced with small diameter PVC. Because the tube was used,
Due to reasons such as 1) presence or absence of infiltration water, 2) connectivity, and 3) delays in construction work, it has been replaced by PVC reservoirs and has become widespread.

Incidentally, in a general reservoir, particularly a reservoir with an elbow-type trap, the trap should be provided and fixed on the outflow side of the masturbator. The trap should have an inner diameter of 75 mmφ or more and a sealing depth of 75 mm to 100 mm, and the backflow of odor will not occur. Not that
The depth of the square is at least 150m from the bottom of the trap
There are established installation standards such as that it is desirable to have m.

[0011] The applicant of the present invention has proposed the following (Japanese Patent Laid-Open Publication No. 9-24) for such an elbow-type PVC reservoir with a trap.
No. 2174) and commercialized.

That is, to briefly explain, as shown in FIG.
1. One sideways inlet port 62, the other side outlet port 63, and a deep-bottomed, slightly-bottomed bottomed cylindrical body 64 are integrally formed. The bottomed cylindrical body 64 has a sediment container (bucket).
65 are removably accommodated.

An elbow 66 is integrated with the sediment container 65 so that both can be taken out simultaneously. The horizontal opening of the elbow 66 is connected to the outlet port 63, and the vertical opening 67 faces the inside of the deposit container 65.

An elbow bracket 68 in the form of a curved plate is integrally formed and provided upright on the outlet side of the upper opening of the sediment container 65. The bracket 68 has an elbow insertion opening. Have been.

Accordingly, the elbow 6 is inserted into the elbow insertion port.
6 is inserted with the tube axis of the vertical opening 67 being horizontal, and this is inserted while gradually making it vertical, and then the elbow 66 is inserted.
The elbow 66 can be set on the bracket 68 by making the pipe axis of the horizontal opening portion horizontal.

Further, the sediment container 65 is provided with a cylindrical body 6 having a bottom.
4 are taken out along the vertical slide groove.

[0017] Therefore, according to the PVC reservoir with the elbow-type trap proposed as above, the sediment container 65 and the elbow 66 are integrated and can be taken out at the same time. Operations such as cleaning and assembling become easy, and in particular, if the sediment container 65 is taken out, it is possible to easily take out fats and oils in drainage.

Further, by taking out the elbow or the like in the vertical direction, the above-mentioned actual fairness 1-41832 can be obtained.
It is not necessary to rotate the elbow type trap in the reservoir as in the publication, which is convenient for the small diameter reservoir.

[0019]

However, it has been found that such a proposed reservoir made of PVC with an elbow trap has the following problems.

When the sediment container 65 having no drain hole is used, the oil and fat floating in the container can be taken out, but after the container is taken out, the container is again put into the bottomed cylindrical body 64. At the time of storage, if drainage remains in the bottomed cylindrical body 64, the drainage resists and the container storage operation becomes difficult. If it is used, oil and fat cannot be taken out), and furthermore, if drainage dirt or earth and sand adheres to the bottomed cylindrical body 64, it becomes even more difficult to store it.

For this reason, the sediment container is stopped, and as shown in the above-mentioned Japanese Utility Model Publication No. 1-41832, the outflow pipe is slightly protruded into the reservoir, and the collar having the elbow rotation locking projection is removed. It is conceivable that the outflow pipe is adhesively bonded and fixed to the end of the outflow pipe, the elbow is moved to the collar in a horizontal direction, and then the elbow is rotated and detachably mounted. A small-diameter reservoir that takes off and attaches it by sliding the elbow up and down so that it can be retained cannot be adopted because there is not enough space for the work.

In the case of the small-diameter reservoir made of PVC, a special effect can be exhibited as compared with the reservoir made of concrete as described above, but the inlet port 62 and the outlet port 63 for the outlet are provided on the main body 60. Since it is integrally molded at the production plant, the depth of buried various drainage pipes at the construction site (for example, in the case of drainage pipes with a predetermined slope from the starting point, the burial depth differs between the starting point and the public square. In particular, it becomes remarkable in drainage pipes of commercial cafeterias with relatively large premises, etc.).

In a conventional general storage with an elbow trap (although a double trap avoiding device is known in an elbow trap with an inflow side pocket), no consideration is given to avoiding a double trap.

Accordingly, the present invention has as its main object to solve the above problems and not only makes it as simple and inexpensive as possible, but also at the construction site as well as at the site where the concrete is stored. The secondary purpose is to provide a responsive synthetic resin reservoir.

[0025]

In order to solve the above-mentioned problems, the present invention has the following features. 1) An outflow / inlet opening on the side and a bucket-like shape with an elbow-type trap having a lid detachably attached to the upper opening. In the synthetic resin reservoir, an elbow is mounted near the outlet on the inner surface of the main body, and a slide groove that allows vertical sliding is formed integrally with the main body when forming the main body, and the elbow is mounted in the vertical direction. The elbow-type synthetic resin reservoir with a trap, characterized in that the elbow is made to be able to be removed from the main body by sliding the elbow to the inner surface of the main body as much as possible.
There is an outflow / inlet opening on the side, and a lid that can be attached to and detached from the upper opening. A flange having a flange joined to the inner surface thereof, and a branch pipe connected to the outflow pipe is inserted into an outlet of the main body, and a member for cooperating with the flange is provided to clamp the main body from the outer surface to fix the branch pipe. ,
A synthetic resin reservoir with an elbow-type trap, wherein an elbow is mounted on the flange, and a slide groove is provided so as to be slidable up and down, and the elbow is slid up and down so that the elbow can be removed from the main body. In
In addition, 3) at least the inflow port of claim 1 or 2 is opened at the construction site in accordance with the construction site, so that there is no inconsistency in the connection and the synthetic resin reservoir with an elbow type trap improves the reliability after embedding. And 4) a reservoir made of synthetic resin with an elbow-type trap in which an elbow according to claim 1 or 2 is provided with an openable / closable breather tube to avoid a double trap. .

FIG. 6 shows a packing used in FIG. 1, and the same parts as those in FIG. 8 showing the conventional example use the same terms.

First, the outline of the synthetic resin reservoir (1) according to the embodiment of the present invention will be described. 1, 2 and 6
The reservoir 1 is a small-sized oil-proof basin made of synthetic resin (for example, hard vinyl chloride resin or PP resin plus calcium carbonate). It is suitable as an oil interceptor for intercepting, and is classified as a reservoir with an elbow trap.

The shape thereof is very simply formed into a so-called large-sized plastic bucket having good injection moldability and easy cleaning. For example, the upper opening has a size of about 345 mmφ and a depth of about 500 mm. Therefore, a mold such as a polybucket which is mass-produced and inexpensive can be diverted and used.

The main body 2 of the reservoir 1 is composed of a bottomed cylindrical body which is an injection molded product slightly squeezed downward, and a composite resin lid 3 similar to the main body 2 is provided in the upper opening. It is detachably covered in a sealed manner.

In the cover structure, a fitting groove 4 is provided around the upper opening of the main body 2, and the fitting groove 4 is formed on the inner peripheral surface of the lid 3 whose center part is slightly convex. The circular fitting recesses 5 are closely fitted so that they do not come off accidentally.

An anti-slip pattern 6 is formed on the outer surface of the lid 3 and is particularly flush with the ground surface without heavy road load (vehicles or the like). Further, a plurality of vertical ribs 7 are provided on the bottom side of the bottomed cylindrical body of the main body 2 to maintain strength even if the amount of storage increases.

In the reservoir 1, the inflow pipe 8 (see FIG. 6) made of a PVC pipe is opened by a hole so as to match the construction site (particularly, according to the depth and direction of the inflow pipe). Is simply inserted and connected to a packing 9 with ribs (see FIG. 6) fitted into the inflow port (no symbol).

An outflow pipe made of a PVC pipe (see FIG. 2)
10 is adhesively connected to a standard socket (also called DS) 11 set on the main body 2. This socket (for example, 100 mmφ) 11 stores with an elbow type trap. However, since the sealing depth and the depth are regulated, the outlet 12 is opened at the production factory, and the socket is set in the main body 2 in advance. However, like the inlet, the outlet 12 may be opened and set in accordance with the construction site.

Here, the reservoir 1 is provided with an elbow 13 forming a trap so as to be freely taken out as follows.

First, an outline of the elbow 13 will be described. 1 and 2, the horizontal opening 1 of the elbow 13 is shown.
The opening 4 is connected to the outlet 12, and the vertical opening 15 is opened toward the bottom of the main body 2 via the perforated plate 16.

The elbow 13 is an elbow mounting branch pipe 1 for setting the socket 11 on the main body 2.
7 are fitted in the vertical slide grooves 18 provided in the vertical direction so as to be able to be taken out in the vertical direction. The top of the elbow 13 has a double trap avoiding breather tube 19.
The breather tube 19 can be opened and closed freely, and serves as a handle for taking out an elbow.

With the above structure, the presence or absence of the double trap is confirmed, and the main body 2 having at least the inlet opening is buried in accordance with the construction site. Miscellaneous wastewater from homes and the like flows into the main body 2 through the inflow pipe 8, and the elbow 13
Through the outflow pipe 10 to a sewer main pipe (not shown). At that time, if fats and oils are mixed in the wastewater, the fats and oils in the wastewater once stored in the reservoir 1 float up, and only the wastewater flows out through the vertical opening 15 of the elbow 13.

Then, the lid 3 is opened regularly or irregularly, and the standing up breather pipe 19 is gripped to hold the elbow 1.
After the slide 3 is taken out by sliding it upward, the oil and fat in the main body 2 is drawn out and cleaned without the elbow 13.

Of course, the work of taking out the soil and the like accumulated in the storage 1 and the cleaning of the perforated plate 16 of the elbow 13 are performed, and the elbow 13 is slid down to the main body 2 to be mounted again.

Therefore, the synthetic resin elbow-type trap with a trap, particularly an oil-proof trough, has a very simple structure, so that it can be used for other rainwater bodies or the like (used also as a molding die) and inexpensive. Of course, it is not only easy to clean, but also extremely easy to handle, which can contribute to the reduction of the burden on the sewage treatment plant.

In particular, since the elbow mounting branch pipe 17 also serves as the vertical slide guide groove of the elbow 13 and the connection of the outflow pipe 10, the number of parts can be reduced, and the structure, handling, price, etc. for a small diameter reservoir can be saved. It is very convenient in this respect.

The opening of the main body 2 for connecting the inflow pipe 8 and the outflow pipe 10 is opened according to the construction site.
There is no inconsistency with the drain pipe, and thus, even after the burial of the pool 1 is buried, it can be made highly reliable without infiltration water.

Next, the elbow 13, the perforated plate 16, the breather pipe 19 for avoiding double traps, and the elbow mounting branch pipe 17 will be described in detail.

The elbow 13 is an injection-molded product made of a synthetic resin (especially ABS resin) having a thickness of 3.5 mm in FIG. 3, and the vertical opening 15 side is about 100 mm × 11 in horizontal section.
It is formed in a square shape of 5 mm square to increase the flow passage area as much as possible and to approach the outlet 12 side in the main body 2 more and more.

The horizontal opening 14 is, of course, formed in the outflow pipe 10.
It has a size and shape (circular) that can be connected smoothly.

An elbow flange 20 in the shape of a square curved plate having an outer curved surface radius of 90 mm is integrally formed on the outer periphery of the horizontal opening portion 14, the left and right edges thereof have a thickness of 15 mm, and the upper and lower edges are respectively provided on the edge end surfaces. A pair (broken) of vertical slide protrusions 21 and 21 is provided.

The slide ridge 21 fits into the slide groove 18 provided in the elbow mounting branch pipe 17 in FIG. 2 and slides up and down. Of course, the interrupted slide ridge 21 reduces the slide resistance, but may be a single continuous ridge.

A horizontal opening 1 is formed on the outer surface of the curved plate of the elbow flange 20 (the center of the main body 2 is inside, the same applies hereinafter).
A packing groove 23 into which the rubber packing 22 is inserted is recessed in the concentric outer periphery of 4. A lower protruding portion (bank of the groove) 23 a of the packing groove 23 is a contact portion of the stopper 24 of the elbow mounting branch pipe 17. In addition, this packing groove 2
3, cutouts 25, 25 are provided at upper and lower positions to facilitate mounting and dismounting of the packing 22.

At the top of the elbow 13, a mounting tube 26 for externally fitting and adhesively bonding the double trap avoiding breather tube 19 is integrally formed and protrudes upward. Since the mounting pipe 26 is closed during molding, the breather pipe 1 is formed.
When fitting 9 outside, the upper part is cut off.

Next, the perforated plate 16 will be described. In FIG. 1, the perforated plate 16 is formed as a deep-bottomed (hat-shaped) perforated plate that is immersed and fixed in the vertical opening 15 of the elbow 13, and the depth of the mud in the small-diameter reservoir 1 (150 mm or more). Standard depth) and the specified sealing depth (Fig. 1)
100 mm).

As a result, in the perforated plate 16, long slits 16a can be opened on the outer periphery and the ceiling of the hat, and the entire slit opening area is enlarged to prevent clogging.

Next, a breather tube 19 for avoiding a double trap.
When a trap function is provided on the inflow pipe 8 side, for example, when an instrument trap is provided, a double trap is formed.
The trap function has been eliminated.

For this reason, a ready-made small-diameter pipe (20 mmφ) of a breather pipe 19 is externally fitted to the mounting pipe 26 of the elbow 13, and a small elbow 27 is externally fitted to this breather pipe 19 and bonded to the same. The plug 28 is detachably mounted on the small elbow 27.

The trap function of the elbow 13 is adjusted by attaching and detaching the plug 28 as required. Further, since the small elbow 27 is provided, the breather tube 19 becomes a key and can be used as a handle for taking out the elbow 13. Needless to say, as shown in FIG. 5, the breather pipe 19 without the small elbow 27 may be used, or the mounting pipe 26 may be formed to be long and have no breather pipe to form a double trap. Only the top surface may be cut off.

Next, the elbow mounting branch pipe 17 will be described. The elbow mounting branch pipe 17 is a hard vinyl chloride resin injection molded product, and its structure will be described.

Originally, a general 90 ° branch pipe is a rubber ring socket to be joined to the outer surface of a large-diameter pipe (for example, a sewer main pipe). In this elbow mounting branch pipe 17, as shown in FIG. A junction type, and the outflow pipe 10 can be connected.
Further, the main body 2 is a spigot type having a spigot for the socket 11 sandwiching the main body 2 from the outer surface. That is, the elbow mounting branch pipe 17 can be said to be an inner surface joined and spout type branch pipe.

That is, the elbow mounting branch pipe 17 has a quadrangularly curved plate-like branch pipe flange (also called a skirt) 29 that is closely joined to the inner surface of the main body 2 and cooperates with the branch pipe flange 29. The socket 11 is configured to have a socket 11 for holding the main body 2 from the outer surface by adhesive bonding.

Therefore, the slide groove 18 is formed in the branch pipe flange 29, and the main body 2 and the socket 11 are formed.
And the joints are strengthened, and the watertightness is improved. In particular, a packing groove 31 for fitting a rubber packing (no reference numeral) is formed on the outer surface of the branch pipe flange 29 for water-tight joining with the main body 2.

The elbow mounting branch pipe 17 is connected to the elbow 1
In order to attach 3, the vertical slide grooves 18, 18 are formed on the left and right sides of the inner surface of the branch pipe flange 29, and the slide ridges 21 of the elbow 13 are fitted. A stopper 24 is provided on the lower side of the branch pipe flange 29 so as to project inward to serve as a stopper for sliding the elbow 13. In addition, in FIG. 4, 32 shows a meat scum.

In addition, instead of the socket 11 which cooperates with the support flange 29 of the elbow mounting branch pipe 17 and clamps the main body 2 from the outer surface, a screw is engraved on the outer surface of the spigot 30 and a nut to be screwed thereto is engaged. It may be.

Of course, the present invention may be used for mere storage.

Next, another embodiment of the present invention will be described.
An elbow-type trap in which the elbow mounting branch pipe 17 and the socket 11 are integrally formed at the time of injection molding of the main body 2 to fix the elbow 13 as close as possible to the inner surface of the main body 2 and further reduce the number of parts. A description of the synthetic resin reservoir is provided.

That is, the outlet port (63) for connecting the outlet pipe 10 is formed on the side surface of the main body 2 in FIG.
And a pair of slide rails connected to the vertical ribs 7 are provided on the inner surface of the main body 2 where the outlet is provided.
8 and 18 are formed, and the slide groove 18 is formed from above to halfway, instead of the stopper 24.

With this configuration, the slide groove 1
There is no particular cause of undercut in the molding of the stopper 8 and the stopper 24. The elbow 13 having the elbow flange 20 can be used as it is in the slide groove 18.

Of course, if the strength is sacrificed, this slide rail may be joined with an adhesive after the injection molding of the main body 2.

[0066]

According to the present invention, not only is the structure extremely simplified and inexpensive, but of course, if the size is too complicated, the work for removing dirt is doubled. Not only can it be easily done, but also it can be easily installed and handled, preventing clogging of the sewer pipe and reducing the burden on the sewage treatment plant. In addition, the sliding grooves are increasingly reinforcing the body.

In particular, since the elbow of the elbow trap is slid up and down by a slide groove provided directly in the vicinity of the inner surface of the outlet for connecting the outflow pipe, and is mounted or removed, a small-diameter reservoir is stored. The work becomes very convenient.

Further, since the vertical opening of the elbow is always regulated in the vertical direction, the positioning can be ensured and the elbow can be set as close to the inner surface of the main body as possible.

According to the second aspect of the present invention, in addition to the above, the elbow mounting branch pipe can serve both for mounting the elbow and for connecting the outflow pipe, and the number of parts can be reduced.

In particular, the outlet pipe can be mounted at any position even if it is manufactured by a production factory, so that the reservoir can have a variety of positions.

According to the third aspect of the present invention, since the storage is suitable for the construction site, the reliability after burying is improved.

According to the fourth aspect, by opening and closing the breather tube,
Not only can a double trap be avoided, but anyway, the outflow is obstructed by the elbow, but since the breather tube is provided on the outflow tube side, this outflow can be made smooth.
