DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reservoir with an elbow having functions such as deodorization, sedimentation and dust removal.

[0002]

2. Description of the Related Art In general, drainage equipment is provided with ancillary equipment that performs functions such as deodorization, blocking of oil and fat, and sedimentation. A typical example of the deodorizing device is a trap box. As is well known, this trap box is provided with a PVC drainage tank with a U trap and an elbow or a cheese at the outlet of a concrete drainage tank with a mud reservoir. The reservoir is provided with a trap and is formed into a trap (hereinafter, referred to as an elbow trap reservoir).

[0003] This reservoir with an elbow trap is, for example,
It is installed in places such as cafeterias and fresh food handling facilities where solids such as residues are mixed into drainage and interferes with sewage mains, and in general home drainage systems in drains connected to the kitchen.

[0004] Further, the following installation standards are established for the reservoir tub with an elbow trap. That is, the trap is provided and fixed on the outflow side of the box, the trap has an inner diameter of 75 mmφ or more, the sealing depth is 75 mm to 100 mm, there is no backflow of odor, and the depth of the box is at least 150 mm from the lower end of the trap. It is desirable that such installation standards be established.

[0005] By the way, various proposals have been made for a reservoir tub with an elbow-type trap which conforms to such a criterion and is PVC. Looking at these proposals, it can be seen that an elbow or a tooth is detachably fixed to the box body (see, for example, JP-A-6-193127) and a non-detachably fixed (for example, JP-A-6-101263). However, in the latter case, for example, in the above-mentioned Japanese Patent Application Laid-Open No. 6-101263, a trap is formed by detachably fixing an elbow to the outlet side of a cell, and a trap is formed inside the cell body. An elbow-type trap in which a sediment container (also called a mud bucket or a garbage basket) is housed, and a partition plate integrated with the sediment container is erected between the elbow and the sediment container. An accumulator basin is introduced.

[0006]

Therefore, an analysis of these proposals reveals that, in the former case, the elbow-type trap basin with an elbow removably fixed to the basin body, the elbow is removed from the basin body. When cleaning, etc., the elbow is once moved to the center of the basin along the pipe axis on the outflow side, then removed, and then taken out of the basin, so reduce the diameter while increasing the amount of mud pool. However, there is a problem that the attachment / detachment of the storage tank with the trap is difficult or impossible.

[0007] The above-mentioned Japanese Patent Application Laid-Open No. Hei 6-1 belongs to the latter.
In the reservoir with an elbow trap in which the elbow described in JP-A No. 01263 is non-detachably fixed to the box body, it is impossible to take out the elbow, and the elbow and the sediment container are juxtaposed in the box body. Therefore, there is a problem in that it is not preferable for a reservoir having an elbow-type trap having a small diameter, and it is troublesome because the fixed elbow and the sediment container are separately cleaned.

[0008]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to solve these problems, and more particularly, by providing a small-sized reservoir tub with an elbow-type trap made of PVC, which has been reduced in size. It can be easily buried in residential land, is inexpensive, and aims to extend the maintenance period.

FIG. 5 is a main part view of FIG. 1, FIG. 6 is another main part view of FIG. 1, FIG. 7 is a plan view of FIG. 6, and FIG. FIG. 9 is a main part side view, and FIG. 9 is still another main part view of FIG.

The present embodiment is directed to an elbow-type trapping basin composed of a basin body having a bottomed cylindrical portion,
It is suitable for a PVC storage tank to which a small-diameter (for example, 250 mmφ) inspection tube or lid frame can be attached, and by adding an odor-preventing function (trap function) to it, drainage, rainwater, or a combination thereof. It can be installed in drainage facilities in homes, public basins, and also in cafeterias and fresh food handling facilities, especially in narrow lands, to be convenient.

First, the reservoir 1 with an elbow trap will be outlined. Mainly in FIG. 1, the measuring box main body 2 has an inspection tube receiving port (a lid frame for fitting a manhole cover may be directly joined, or an insertion port or a rubber ring receiving port).
In one side, the inlet for the inlet (may be an inlet or a rubber ring socket) 4, on the other side, the outlet for the outlet (may be an inlet or a rubber ring socket) 5, downward deep bottom, Further, the bottomed cylindrical bodies 6 slightly narrowed down are integrally formed. The inlet port 4 is located on the same tube axis as the outlet port 5 in plan view, and is opened upward from the inlet port 5 with a slight difference in water level (for example, 20 mm). The bottom cylindrical body 6 has a perforated bottomed cylindrical sediment container 7 having substantially the same shape and as large a capacity as possible, and is placed and accommodated so as to be able to be taken out. In addition, the bottomed cylindrical body 6 may be configured as a detachable separate body (for example, Japanese Patent Laid-Open No. 7-292).
758).

The reservoir with trap has an outlet 5 for outlet.
Is connected to an elbow 8 to form a trap. The lower opening 27 of the elbow 8 faces the inside of the deposit container 7. Therefore, it is convenient to reduce the diameter of the reservoir with the elbow trap.

The above-described reservoir 1 with an elbow trap
For example, when used as an auxiliary equipment of a home drainage system, drainage mixed with solids flows in through an inlet (also referred to as an inflow opening) 4a and flows out through an outlet (also referred to as an outflow opening) 5a. This solid (for example, earth and sand,
Litter, vegetable debris, or contaminants such as residue) are settled and deposited in the sediment container 7, and the wastewater excluding the solids flows out to the sewage mains. At this time, the odor flows backward from the sewage main pipe or the like to the outflow port 5a, but this odor is sealed by the elbow 8, so that it leaks not only into the inflow port 4a but also into the tub body 2. Nothing.

The solid matter deposited in the sediment container 7 may be discharged simultaneously with the elbow 8 or as described later.
Remove and clean the entire container separately.

In this case, the reservoir 1 with an elbow trap is designed to reduce the diameter of the reservoir while increasing the amount of mud reservoir as much as possible. In order to facilitate cleaning, a structure is adopted in which the sediment container 7 and the elbow 8 are detachably integrated, or the sediment container 7 and the elbow 8 are separated and integrated with an adhesive or the like so that they can be taken out simultaneously. ing.

Hereinafter, the details of such a structure will be referred to as “measuring body 2”,
The “deposit container 7”, the “elbow 8”, and the “packing 34” will be described separately.

First, the "cell body 2" will be described. Mainly in FIGS. 5, 2 and 3, the box main body 2 is a PVC injection molded product, and the inspection tube receiving port 3 is formed as follows.

That is, the home drain pipe to be connected is 75 mm
When the opening diameter of the sediment container 7 is about 150 mmφ in the case of φ to 200 mmφ, for example, 90 mmφ, since the elbow 8 is integrated with the sediment container 7, the diameter of the inspection port 3 is reduced. It is formed to about 200 mmφ. Therefore, even if the diameter of the inspection tube receiving port 3 is enlarged from the opening diameter of the sediment container 7 (for example, the container opening diameter 3 to the receiving port diameter 4) and reduced by a lid frame (not shown). Easy to put.

The opening of the sediment container 7 has an outlet 5a.
Approximately matches the bottom of the tube. For this reason, a step 4b is formed between the inflow port 4a and the sediment container 7, and there is a possibility that solid matter is accumulated, but the injection molding of the cell body 2 can be facilitated.

The overall shape of the bottomed cylindrical body 6 of the box body 2 is formed so as to substantially match (substantially the same shape) as the shape of the deep bottom bucket-shaped deposit container 7. Then, from the vicinity of the outlet 5a to the upper end of the bottomed cylindrical body 6, the outlet 5a
A pair of upper and lower slide L-shaped grooves (also referred to as stationary guide portions) 10 and 10 are formed with “a” interposed therebetween.

Therefore, as shown in FIGS. 3 and 5, the curved surfaces A and B having different radii are formed near the outflow port 5a and the cylindrical surface of the cylindrical body 6 having a bottom. Is larger (or smaller) than that of the curved surface B, and
The curved surface A occupies two-thirds or more of the body curved surface of the bottomed cylindrical body 6. As a result, the volume of the bottomed cylindrical body 6 is made as large as possible to secure a water storage amount, and it is possible to cope with a large amount of temporarily drained water.

The pair of upper and lower slide L-shaped grooves 10, 1
0 and a fitting U-shaped groove 11 connecting the lower ends of these upper and lower sliding L-shaped grooves 10, as described later,
While accurately positioning the stored sediment container 7,
This sediment container 7 can be firmly fixed to the box body 2, and thus, the elbow 8 can be accurately positioned at the outlet 5 a and firmly fixed.

Next, the "deposit container 7" will be described.
Mainly in FIGS. 6, 7, 8 and 2, the sediment container 7 is a PVC or ABS injection-molded product, and employs a deep bottom type in order to increase the amount of accumulation as much as possible. For example, the opening diameter is about 150 mm, and the bottom diameter is about 140 mm.
, The depth is set to approximately 240 mm.

The bottom 12 of the deposit container 7 has a plurality of holes 1.
Are provided to drain the wastewater and drain the water when the container is taken out.

The body 14 of the sediment container 7 flows out,
The sides perpendicular to the pipe axes of a and 4a are formed on the flat surface 15, and a slightly large space is formed between the side and the bottomed cylindrical body 6 of the box body 2 to secure the water storage amount and always stand upright. When the handle 16 is moved in and out of the box body 2, it is prevented from interfering.

However, since the later-described flange 19 extends from the open end of the sediment container 7 and is joined to the inner surface of the bottomed cylindrical body 6, solids flow directly into the bottomed cylindrical body 6. I will not do it.

Further, in the state in which the sediment container 7 is housed, the body portion 14 is formed with a curved surface 17 having a larger radius on the inlet 4a side and a curved surface 18 with a smaller radius side on the outlet 5a side. To fit the curved surface of the bottomed cylindrical body 6. Therefore, although the sediment container 7 is substantially joined in the bottomed cylindrical body 6 in a loosely fitted state, it does not move around.

The outer periphery of the opening of the sediment container 7 is
A flange 19 formed with two radii is extended, and the outlet 5a side of the flange 19 cuts out a portion where an elbow bracket 21 described later is erected and its vicinity 20.

At the opening 5a side of the opening of the deposit container 7, an elbow bracket 21 in the shape of a curved plate is integrally erected (integrally formed). This elbow bracket 2
In particular, as shown in FIG.
An edge raised portion 22 having the same height as the collar width of No. 9 is provided,
The inflow of solid matter into the bottomed cylindrical body 6 is prevented.

An elbow insertion hole 23 is opened at a position facing the outlet 5a in the elbow bracket 21, and a ring-shaped raised portion 24 is provided on the outer periphery and outside of the elbow insertion hole 23. . This ring-shaped ridge 24 is lower than the height of the edge-shaped ridge 22,
Even if the back surface of the elbow flange 30 of the later described elbow 8 abuts, it protrudes into the box body 2 so as not to interfere with its inner surface. On the concentric outer periphery of the ring-shaped protruding portion 24, a packing fitting protruding portion 25 having the same height as the edge protruding portion 22 and partially overlapping is provided.

In the ridges 22 at the left and right ends and at the lower end of the elbow bracket 21 (which overlap with a part of the ridges 25 for packing fitting), vertical slide L-shaped grooves provided in the box body 2 are provided. Insert pieces 26, 26, 26 to be inserted into the fitting 10 and the fitting U-shaped groove 11 are formed.
The insertion pieces 26, 26 inserted into the vertical slide L-shaped grooves 10, 10 are also referred to as vertical slide guides.

Next, the "elbow 8" will be described. 9 (A) and 9 (B) and FIG.
Is polyethylene or a similar resin, for example, a PVC injection-molded product, the lower opening 27 of which is formed of a normal pipe,
The upper opening 28 is constituted by an eccentric enlarged portion 29 having the same tube bottom. An elbow flange 30 is formed at the open end of the eccentric enlarged diameter portion 29, and the elbow flange 30 is formed.
This prevents the elbow 8 from being pulled out when the elbow 8 is mounted on the elbow bracket 21.

That is, the back surface of the elbow flange 30 comes into contact with the ring-shaped raised portion 24 of the elbow bracket 21 as described above, and the elbow flange 30 and the locking portion 3
1, the ring-shaped ridge 24 is gripped. For this reason, the locking portion 31 is provided with the eccentric enlarged diameter portion 2.
9 is formed lower than the packing fitting raised portion 25 on the outer surface of the back portion.

Therefore, in order to insert the elbow 8 into the elbow insertion hole 23 of the elbow bracket 21 in a vertical state and mount it, first, the pipe shaft of the lower opening 27 of the elbow 8 is inserted horizontally. , And gradually insert it vertically. Then, the upper opening 28 of the elbow 8
If the eccentric locking portion 31 is tilted while the pipe shaft is slightly inclined to the upper left in FIG.
You can get over 3. Then, the upper opening 28
If the tube shaft is made horizontal, the locking portion 31 and the elbow flange 30 face each other, the ring-shaped raised portion 24 can be held, and the elbow 8 can be prevented from coming off.

In order to make the lower opening 27 of the elbow 8 as close to the elbow bracket 21 as possible, the following configuration is adopted.

That is, FIG. 9 (B) (D ~ of FIG. 9 (A))
As shown in an arrow cross-sectional view), the curved outer surface 32 of the elbow 8 is formed of a normal elbow arc, and the curved inner surface 33 is short-circuited as much as possible. It is composed of surfaces 33a and 33b. Moreover, the curved outer surface 32 adopts the normal pipe diameter R1, but the curved inner surface 33
Are elliptical and smooth the inner surface of the elbow 8. R2 indicates the radius of curvature of the elliptical curved surface. Even in this case, since the drainage rises from the lower opening 27, there is no obstacle to the flow.

Next, the "packing 34" will be described.
In FIG. 3, the packing 34 is made of synthetic rubber, is formed in a U-packing shape, and has a thick portion 35 at the U end on the inner diameter side. That is, a modified U packing is used.

This packing 34 is mounted between the packing fitting raised portion 25 and the ring-shaped raised portion 24 of the elbow bracket 21, and the elbow flange 30.
The thick part 35 is held on the back surface of. Therefore, the packing 34 seals the space between the elbow bracket 21 and the box body 2 and thus seals the outlet 5a and the elbow 8 to prevent odor from leaking. That is, the deodorizing function is improved. Of course, when the packing 34 is not used, it can be applied to dust removal and oil / fat blocking.

The packing 34 may be of various shapes such as V packing, W packing, O-ring, lip packing, and gland packing.

Next, another embodiment of the present invention will be described. A step 4b was formed between the pipe bottom of the inflow port 4a and the opening of the sediment container 7 in the box body 2 described above.
In the box body 2A of the embodiment shown in FIG.
b is eliminated as much as possible to prevent stagnation of solids. That is, the flange 19A of the opening 36 of the sediment container 7 is inclined inward, and the outer periphery of the flange 19A is connected to the inlet 4a.
As close as possible. Therefore, a cutout step 37 is formed on the outflow port 5a side of the opening 36 of the deposit container 7 so as not to hinder the attachment of the elbow 8.

In each of the above embodiments, the elbow 8 is used.
Is attached to the bracket 21 for the elbow detachably integrated with the sediment container 7, but the present invention is not limited to this. After being placed on or suspended from the stack, a curved plate (not shown) having an upward U-shaped notch (which allows the horizontal portion of the elbow to be fitted therein) standing upright in the sediment container 7 is used as an elbow bracket. Between the elbow bracket and the inner surface of the box body 2, or on a stationary guide formed on the box body 2,
The elbow 8 may be attached by inserting the elbow flange 30. In this case, the elbow 8 may be provided with a separate handle for access, but at the time of removal, if the sediment container 7 is removed, the elbow 8 can be removed together therewith. Is not required.

Further, the bottomed cylindrical body 6 does not necessarily have to be a cylindrical body, and when the reservoir of the present invention is applied to a drainage tank, the elbow 8 is connected to the inflow opening.

[0043]

According to the first aspect of the present invention, the bottomed cylindrical body 6 of the box body is provided.
Since a sediment container of approximately the same shape is accommodated and the lower opening of the elbow is exposed, the diameter of the reservoir with an elbow trap, which does not hinder even if the amount of sedimentation increases, is reduced to a small area and In addition to being suitable, it can be inexpensive, and thus can greatly contribute to the spread of drainage facilities and the reduction of the burden on sewage treatment plants.

According to the second aspect of the present invention, in addition to the above, since the sediment container and the elbow are integrated, they can be put in and out of the container at the same time, and cleaning and assembling operations of the heavily soiled sediment container and the elbow can be performed. It becomes easy and can conveniently perform functions such as dust removal and oil / fat blocking.

According to the third aspect, in addition to the above, functions such as trap formation and dust removal can be conveniently performed.

According to the fourth aspect, since a packing is interposed in addition to the above and the above, a further deodorizing function can be exhibited.

According to the fifth aspect of the present invention, in addition to the above and the other, the deposit container and the elbow can be easily put in and out, and the connection between the upper opening and the outflow opening can be ensured. That is, the elbow can be securely fixed to the outflow opening.
