Abstract

PROBLEM TO BE SOLVED: To perform high-efficient cleaning by a method wherein a front chamber to separate oil and a rear chamber forming a screen wall to catch a solid, which are partitioned by a partition plate having a lower end being opened are arranged in a refuse container removably contained in a sewage basin. SOLUTION: A sewage inflow port 12 and a sewage outflow port 13 are formed in an inlet body 11 to connect together a sewage inflow port 21 and a sewage outflow port 22 and the inlet body forms an injection moulded product of synthetic resin together with a cover 14. A refuse container 3 is partitioned into a front chamber 321 fronting on a sewage inflow port 12 and a rear chamber 322, except the lower end part of a side wall, forming a screen wall 323 by a partition plate 31 having the lower end part being opened. A handle 331 is hooked at a hook 332. Inflow miscellaneous drain separates an oil content in the front chamber 321 through gravity and a solid foreign matter, such as rice grains, hairs, and yarn dust, is captured from oil content-separated liquid, flowing in through the open passage of the lower part of the partition plate 32, through the screen of the rear chamber 322. This constitution recovers and disposes an oil content and sludge with high efficiency, resulting in facilitation of cleaning of a sewage inlet through the reduced number of processes.

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a wastewater mass.

[0002]

2. Description of the Related Art In order to guide miscellaneous wastewater from each household to a public sewer pipe, in order to facilitate maintenance and inspection of drainage facilities,
Through the sewage mass. That is, the sewage from the washroom of each home, the sewage from the bathtub / bath, and the sewage from the kitchen sink, etc. are received at the masses of each residential land through the respective sewer pipes, and these receptions are made into public-private boundaries. It collects water through the sewage pipe to the lower mass of the road and guides this sewage into the sewer pipe through the installation pipe.

As a conventional sewage mass, as shown in FIG. 3, a basket (dust collecting container) 3'for receiving sewage from the sewage inlet 12 'is detachably accommodated in the mass body 11', It is known that a trap 31 'is detachably attached to the wastewater outlet 13'. In this sewage mass, solid foreign matter (rice grains, hair, thread waste) contained in the miscellaneous wastewater can be collected by the basket 3 ', and when cleaning the sewage mass,
By removing the basket from the mass body, solid foreign matter can be easily collected. Of course, the removal of solid foreign matter can prevent clogging of sewage and reduce the load of sewage treatment.

Further, the trap 31 'can prevent oil from flowing into the sewer, which not only reduces the sewage treatment load but also raises the position of the sewage outlet 13'.
The burial depth of the dirty water outflow pipe 22 'can be made shallow, and labor saving for excavation can be achieved. Further, the height difference between the sewage inlet 12 'and the sewage outlet 13' can be reduced, and the sewage inlet 12 '
Since the drop between the liquid level in the mass and the liquid level in the mass can be reduced, it is possible to prevent the inflow of sewage from scattering and reliably collect dust in the trap 3 ′.

[0005]

However, in the conventional sewage mass, since the organic suspension is agglomerated and adhered also to the trap, not only the basket but also the trap is removed and cleaned at the time of cleaning the sewage mass. It is necessary to reattach the basket and trap to the mass body individually.

Further, due to the existence of the trap, a considerably large space is generated between the mass body and the basket, and the settling component (excess) in the organic suspension which has passed through the holes of the basket is settled. A sludge layer is formed by depositing on the bottom surface of the space and an oil layer is formed on the liquid surface of the space, and since the space is wide, the sludge amount and the oil amount are large, This large amount of sludge and oil is outside the basket and cannot be collected by pulling up the basket.Therefore, when cleaning the sewage mass, other than removing, cleaning, and reattaching the basket and trap individually, collecting large amounts of sludge and oil. The work is required, and the cleaning work is troublesome because it requires many man-hours.

The object of the present invention is to separate the oil component only by detachably accommodating only the dust container in the mass body, and to remove solid foreign matter, oil components, sludge and the like once when cleaning the mass body by removing the dust container. To provide a wastewater mass that can be collected and disposed of with high efficiency.

[0008]

A waste water mass according to the present invention has a waste container detachably housed in a mass body, and a partition plate with a lower end opened is provided in the middle of the waste container. This is characterized in that the partitioned front chamber faces the sewage inlet, and the side wall of the rear chamber is a screen wall.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a sewage mass according to the present invention. In FIG. 1, 11 is a mass body, and 1
2 is a sewage inflow port, 13 is a sewage outflow port, and 14 is a lid of the mass main body, and injection molded articles of synthetic resin can be used for these. Reference numeral 21 denotes a sewage inflow pipe, which is connected to the sewage inflow port 12 of the mass main body 11. A sewage outflow pipe 22 is connected to the sewage outflow port 13 of the mass main body 11.

Reference numeral 3 denotes a dust container housed in the mass main body 11, and a front chamber 321 is provided by a partition plate 31 whose lower end is opened.
The front chamber 321 faces the dirty water outlet 12, and the side wall of the rear chamber 322 is a screen wall 323 except for the lower end. FIG. 2 shows an example of a garbage container, in which a partition plate 31 is welded to the center of a bottomed metal cylinder, and a partition plate 31 is welded between the lower end 311 and the bottom surface of the cylinder.
The upper end of the side wall of one chamber (front chamber) is cut away with a gap g of about mm between the upper end 312 of the notch and the height slightly lower than the lowest point of the sewage inlet, and the other chamber (rear chamber). The side wall of (1) except for the lower end is formed on the screen 323 by punching with a hole diameter of about 3 mmφ, and the handle 331 is attached.

As shown in FIG. 1, this waste container is housed in the mass main body 11, and the handle 331 is hooked on the hook 332 on the sewage inlet side. The sewage mass according to the present invention can be used, for example, as a mass in a residential area. Thus, in FIG. 1, miscellaneous wastewater generated at home (drainage in the bathroom, kitchen, washroom, etc.) passes through the dirty water inflow pipe 21 and the front chamber 3 of the waste container 3
21, the oil component is gravity-separated in the front chamber 321, and floats above the liquid surface.
Flows into the rear chamber 322 through the lower open passage of the passage, further passes through the screen of the rear chamber 322, and when this screen passes,
The passage of solid foreign matter (mainly rice grains, hair, lint, etc.) in the wastewater is collected and collected, and the miscellaneous wastewater from which oil and solid foreign matter are removed is discharged from the wastewater outlet 13 through the wastewater outflow pipe 22 to the public. It is released into the sewer.

In FIG. 1, the height difference between the wastewater inlet 12 and the wastewater outlet 13 is made sufficiently small (about 20 mm).
The burial depth of the sewage outflow pipe 22 is made as shallow as possible, and the height difference between the sewage inflow port 12 and the liquid level a in the mass main body is small. Therefore, the agitation of the sewage in the sewage due to the inflow of the sewage into the sewage mass can be kept to a slight degree, and the gravity separation in the front chamber 321 can be efficiently performed.

In the sewage mass according to the present invention, the partition plate 31 which is opened at the lower part prevents passage of oil and it is not necessary to provide a trap. Therefore, the waste container 3 has a large volume which substantially occupies the inside of the mass main body 11. It can be done (about twice as much as the conventional one), and the bottom surface of the mass body that is not occupied by the waste container can be made small. In the sewage mass according to the present invention, as described above, the agitation of the sewage in the mass main body 11 is mild, so that the oil can be efficiently separated, but the sedimentation and accumulation amount of the surplus organic matter also increases, and the amount of sludge increases accordingly. Since a layer is formed, and in this case, most of the bottom surface of the mass body is occupied by the bottom surface of the waste container, the sludge layer is formed almost entirely on the bottom surface of the waste container. Therefore, if the waste container 3 is taken out of the sewage mass 11, the sludge in the sewage mass can be almost completely discharged out of the mass main body together with the oil and the solid foreign matter.

When the waste container is taken out of the wastewater mass, if it is taken out rapidly, the outflow rate of the wastewater from the screen of the waste container becomes rapid and the amount of sludge and oil in the waste container increases. In order to prevent this large amount of outflow, as described above, it is preferable that the lower portion of the side wall of the rear chamber is non-perforated (or plate-bonded), and the height of the non-perforated portion is about 50 mm from the bottom surface. Appropriate.

Further, the height of the waste container can be set to be slightly higher than the lowermost surface of the wastewater outlet.

[0016]

EFFECTS OF THE INVENTION In the sewage mass according to the present invention, solid foreign matters (rice grains, hair, lint, etc.) are collected and oil is separated in the trash container without attaching the trap to the sewage outlet. Therefore, when cleaning the sewage mass, it is possible to recover the oil content together with the solid foreign matter by taking out the waste container to the outside of the sewage mass. Therefore, individual removal of baskets and traps, cleaning,
Compared with the conventional example requiring reattachment, only the dust container needs to be removed, washed, and reattached, so that the sewage mass can be easily cleaned with a small number of steps.

Further, since the sludge formed in the waste water mass can be almost recovered by taking out the waste container to the outside of the waste water mass, unlike the conventional example, it is possible to avoid the double labor of recovering the sludge after taking out the basket, The sewage mass can be cleaned more efficiently and easily.
