Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a drainage waste collection basin for collecting waste contained in wastewater from general households, etc.

(Prior Art) As a conventional garbage collection basin of this type, a garbage collector is removably provided within the basin body, as disclosed in, for example, Japanese Utility Model Application No. 54-166777.
The wastewater collector is configured to collect dirt in the wastewater as it flows from the inlet to the outlet, and the dirt collector is periodically removed and cleaned.

(Problem that the invention aims to solve) By the way, a garbage collection basin with this type of structure originally performs its function only when the garbage collector is installed, so it is necessary to remove the garbage collector. It ends up not fulfilling its function at all. Therefore, if the garbage collector is removed for cleaning, if wastewater flows in during this time, or if for some reason you neglect to install the garbage collector after cleaning, the wastewater in the wastewater will be removed. The garbage was discharged downstream without being collected, which could have a negative impact on the pumps at the pumping station in particular. By the way, one of the reasons for neglecting to install the garbage collector mentioned above is, for example, if the garbage collector is for general household use, the householder consciously removes the garbage collector due to the hassle of having to clean it. There are cases where it gets hot.

One possible way to prevent this kind of situation is to fix the garbage collector inside the box itself, but this would make cleaning extremely difficult and make it impossible to expect regular cleaning. .

Furthermore, since the garbage collection basin was not equipped with a trap, there was a problem in that bad odors from downstream flowed back.

(Means for Solving the Problems) The waste collection basin for drainage according to the present invention has a garbage collector removably installed inside the basin body, a trap provided on the outflow side of the basin body, and a trap that is attached to the trap body. An auxiliary dust collection member having a large number of through holes is provided at the inlet portion, and the total opening area of the through holes is set to be larger than the inner diameter cross-sectional area of the outflow pipe.

(Function) When the garbage collector is removed for cleaning,
If wastewater flows into the main body of the trap, or if you neglect to install the garbage collector after cleaning, the auxiliary garbage collection member installed at the entrance of the trap will supplementally collect the bulky garbage in the drainage. to prevent leakage into the outflow pipe. The trap also prevents odors from flowing back from downstream.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

Fig. 1 shows the garbage collection basin for wastewater according to the present invention, and the garbage collection basin 1 mainly collects garbage contained in household wastewater, such as vegetable scraps from the kitchen and hair from the bathroom. This is for collecting garbage within the premises of the city, and consists of a basin body 2, a garbage collector 3, a trap 4, etc., and is buried underground.

The basin body 2 is made of plastic such as low-foam polypropylene or concrete, and has a circular cross section, and has a divided structure consisting of a separation basin body 5, an adjustment ring 6, an inlet ring 7, and an adjustment ring 8. ing. Side wall 5 of separation box body 5
An outflow port 9 is provided at a, and an outflow pipe 10 is connected to this. The outlet 9 is provided above the bottom surface 5b of the separation basin main body 5 so that water 23 always remains in the separation basin main body 4. Further, an inlet 11 is provided in the side wall 7a of the inlet ring 7, and an inlet pipe 12 is connected to this. In addition,
The inflow port 11 and the outflow port 9 are provided facing each other on opposite sides, and the difference in height between these ports is adjusted by a combination of the adjustment ring 6. The upper edge 8a of the uppermost adjustment ring 8 is covered with a lid 13 made of resin concrete or the like.

A partition plate 14 is provided inside the basin main body 2, which vertically partitions the inside into an inflow side and an outflow side. The partition plate 14 is made of plastic such as hard vinyl chloride resin, FRP, stainless steel, etc., and is formed into a circular shape with approximately the same diameter as the inner diameter of the basin body 2, and is located between the inlet 11 and the outlet 9. It is removably provided on the locking part 15 of. The locking portion 15 is applied to the inner side of a fitting groove 16 provided on the upper edge 6a of the adjustment ring 6. Partition plate 14
An attachment hole 14a is provided in the center of the body, into which the dust collector 3 is attached.

The garbage collector 3 is made of stainless steel or the like and has a container shape, and is provided with a large number of drainage holes 17 throughout. A mounting flange 18 is provided on the upper edge 3a of the dust collector 3, and the dust collector 3 is inserted into the mounting hole 14a of the partition plate 14 from above, and the mounting flange 18 is locked onto the partition plate 14. However, the garbage collector 3 is attached in a hanging manner and detachably. 19 is a handle for attachment and detachment.

The trap 4 is for preventing the backflow of odor, and is provided on the outflow side of the basin body 2, that is, at the outflow port 9. The trap 4 is formed into a pipe shape with an open top and bottom, an upper opening 4a serving as a cleaning opening, a lower opening 4b serving as an inlet, and an outlet 20 provided on a side 4c of the trap 4. The end 10a of the outflow pipe 10 is connected to this.
The lower opening, that is, the inlet portion 4b is immersed in and faces the stored water 23, and an auxiliary dust collecting member 21 is provided therein.

The auxiliary garbage collection member 21 is the same as the garbage collector 3.
It has a screen-like shape made of hard vinyl chloride resin, etc. That is,
A large number of through holes 21 are provided throughout the auxiliary dust collection member 21.
a... is provided, and the opening area of the through hole 21a is set to be the same as or larger than the opening area of the drain hole 17 of the garbage collector 3,
The total opening area of all the through holes 21a is set larger than the inner diameter cross-sectional area of the outflow pipe 10.

Further, the cleaning opening 4a of the trap 4 is usually
It is closed by a cap 22.

Therefore, in the garbage collection basin 1 configured as described above, in normal times, wastewater from each household flows into the garbage collector 3 from the inflow pipe 12, and the drainage hole 1
Pass through 7... At this time, garbage larger than the drain hole 17 remains in the garbage collector 3 and is collected, while the filtered waste water flows down and is drained from the outflow pipe 10 via the trap 4. In this normal state, that is, in the state in which the dust collector 3 is installed, the auxiliary dust collecting member 21 of the trap 4 does not function.

On the other hand, the garbage collector 3 needs to be taken out and cleaned regularly, for example, every two weeks, but when the garbage collector 3 is removed for cleaning, there may be cases where wastewater from households comes into contact with the garbage collector 3, Alternatively, if the installation of the dust collector 3 is neglected for some reason after the cleaning is completed, the auxiliary dust collection member 21 functions. That is, this part collects garbage in the waste water, prevents bulky garbage from flowing into the outflow pipe 10, and prevents failure of pumps at downstream pumping stations. In addition, if the garbage collector 3 is not installed for a long time as described above, the auxiliary garbage collector 2 will gradually be installed.
1 will cause clogging and eventually become completely clogged, making it impossible to drain the water itself. Then, the water level flowing into the basin body 2 rises as shown in FIG. 2, and eventually overflows from the lid 13, resulting in a warning being issued to prompt the installation of the garbage collector 3. become. When such a situation occurs, remove the lid 13 and pump out the accumulated water 23 inside the basin body 2, then remove the cap 22 of the trap 4 and clean the auxiliary garbage collection member 21. Then, install the garbage collector 3.

Note that the auxiliary dust collecting member 21 is not limited to the illustrated example, and may have other structures such as a net-like member having the same function.

Further, the structure of the trap 4 can be changed to another structure having the same function, and the cross-sectional shape of the trap body 2 is not necessarily circular.

(Effects of the invention) According to the invention, the trap prevents the backflow of odors, and even when a garbage collector is not installed, the auxiliary garbage collection member functions to supplementally collect garbage. This effectively prevents pump failures at pumping stations by preventing bulky waste from flowing into the outflow pipes.

Further, the clogging of the auxiliary dust collecting member may prompt the installation of a dust collector.
