The present invention relates to a sewage receiving device which effectively prevents odors from entering the home or business while receiving the sewage discharged from a discharge pipe such as a home or a business, and smoothly discharging the sewage into a main sewage pipe or a sewage pipe. , In detail, is provided by combining the sewage inlet connector and sewage discharge connector to two or more through-holes formed in the cylindrical manhole, connects the odor prevention trap to the sewage inlet connector, and the lower end of the manhole to facilitate the discharge of falling water By providing an invert, it is easy to install by providing a sewage receiver that can be customized 1: 1 according to the site situation where the discharge pipe and sewage pipe are different in size or location. It is about a sewage catch that is properly blocked.

In general, the sewage receiver acts as an intermediate septic tank that receives and temporarily stores sewage, and discharges the waste contained in the wastewater again through the drain pipe, or sends wastewater back to the main water pipe through the waste water pipe without filtering waste. The sewage receiving device that performs this function is determined by the installation location and purpose of use.

In the case of the conventional household sewage catcher has been used to divide most of the sewage catcher for household wastewater and toilet bowl for odor because of the odor, which has had a problem to purchase and install at least two sewage catchers separately.

And since the inlet pipe and the discharge pipe of the conventional sewage collector are made of a material with high hardness and their positions are fixed and produced integrally, it is difficult to change the position of the pipe because the piping work must be made according to the structure and shape. If the piping work is done without being there is a problem that the leaking water.

In addition, since the inlet pipe or the discharge pipe is fixed, it is difficult to connect a plurality of drain pipes for discharging the sewage obtained from various places, and the positions of the sewage pipes are different because the sewage is introduced and discharged from structure to structure. Due to the hole formed in the body it is very difficult to accurately connect the inlet pipe or discharge pipe was a very uncomfortable pipe work.

The conventional sewage collecting device is registered in Korean Utility Model Registration No. 0379968 (announced on March 26, 2005), when the sewage is not supplied using a U-shaped trap, the smell is maintained while the inside of the trap is filled with sewage. It provides a deodorizing function to prevent from entering inside.

However, household sewage is often discharged a small amount of water more frequently than when a large amount of water is discharged at once, 'There is a disadvantage that you need to clean frequently because foreign matter is easily caught or stacked inside the trap-shaped trap, but the cleaning It is not easy to be clogged easily and can not perform its function, or if blocked, there is a drawback that the water flow back phenomenon occurs.

The present invention has been made to solve the above problems,

It can be manufactured by assembling without being molded in one piece so that the number, size and location of the inlet and outlet pipes can be accurately selected and piped according to the situation of the site. The purpose of the present invention is to provide a sewage receiver that enables watertightness, prevents odors generated from sewage or wastewater from flowing back, and facilitates the removal of accumulated sewage without mixing with the sewage or wastewater. .

In order to achieve the object as described above, the sewage collector of the present invention,

 An odor prevention trap provided in the manhole and having a curved portion inserted into the sewage inlet connector to allow the introduced filth to flow smoothly into the manhole so that the odor generated does not flow back into the manhole;

It consists of.

In the above, the rigid cylindrical manhole forms a basic frame of the sewage collector buried underground, and should have hardness enough to withstand the vertical and horizontal pressure, and at least two through holes are formed on the outer circumferential surface of the sewage inlet connector and sewage discharge. Allow the connector to connect.

Preferably, the upper part of the cap should be provided to prevent external leakage of odors and safety accidents, and the lid can be opened and closed to check for abnormality of pipes, smooth discharge of sewage, or to remove accumulated dirt. do.

The sewage inlet connector is a portion connected to the discharge pipe of the home or business to receive the sewage or wastewater discharged from the home or business, a cylindrical sewage inlet connector, a tube bolt provided on the outer periphery of the connector, the tube bolt Consists of a tube nut fastened to it.

Preferably, the sewage inlet connection pipe is formed of a cylindrical material as a soft material, and its end portion is formed of a semi-elliptic flange having a diameter larger than the diameter of the through hole so that the discharge pipe of the home can be connected to the through hole. Ensure that watertightness is ensured after insertion.

Preferably, the upper pipe bolt is formed of a cylindrical material as a hard material, and a thread is formed at a predetermined portion of the outer circumference thereof, and an end portion thereof is formed of a semi-elliptic flange, and is formed to be matched to the outside of the sewage inlet connector. do. That is, the inner diameter of one end is made to match the outer diameter of the sewage inlet pipe, and the other end is a semi-elliptical flange having a diameter larger than the diameter of the through hole but can be inserted into the sewage inlet pipe. By being configured so as not to deviate by matching with the sewage inlet pipe.

Preferably, the tube nut is formed of a cylindrical material as a hard material, and a bone is formed on an inner surface of the tube nut to be fastened to the thread of the tube bolt.

The reason for making the shape of the sewage inlet connecting pipe and the pipe bolt in the shape of a semi-ellipse is to match the shape of the through hole formed in the outer periphery of the cylindrical manhole. That is, since the through hole is circularly formed along the curved surface of the manhole outer periphery, the center of the through hole and the circumferential arc portion of the through hole have a depth difference (distance difference when viewed from the side) when viewed from the front. In order to match this depth difference, it is set as the half ellipse shape which cut | disconnected half of the ellipse shape.

And the sewage inlet connector further comprises a washer fitted to the outer periphery of the pipe bolt and tightened by the pipe nut. The washer is made of a hard material and is made of a semi-ellipse shape to increase the tightening force and watertightness by tightening the tube nut, thereby tightening the tightening and preventing leakage of water.

The sewage discharge connector is a portion connected to the pipe connected to the sewage or sewage main pipe is made of the same configuration as the sewage inlet connector.

It consists of sewage discharge connector, pipe bolt, pipe nut and washer. However, since the amount of discharged sewage or wastewater will be greater than the amount introduced, it is preferable that the diameter and size of the sewage or wastewater be larger than that of the sewage inlet connector.

On the other hand, in the sewage inlet connector and sewage outlet connector, the sewage inlet connector and the sewage outlet connector are made of a hard material, and a thread is formed on the outer circumference to connect the nut directly without the pipe bolt. The object of the invention can be sufficiently achieved.

Since the invert is a hard material having a fluidity, that is, a hardness of low hardness, such as PE soft, it is preferable to be formed to some extent fluidity, and the upper part is generally formed in a disk shape, and the lower part supports the upper part and has a predetermined height. Pedestals are formed to hold them. The disc shape is formed to the same outer diameter as the inner diameter of the manhole so that it can be inserted into the inside of the manhole. The pedestal is irrelevant as long as it can support the top, such as a square column or cylinder, and may be any shape as long as it can support the top, even if it is made of a rectangular or cylindrical shape.

The upper invert is formed to have a slope when viewed from the side. The low inclined portion is mounted in contact with the sewage discharge connector so that all of the introduced sewage is led to the sewage discharge connector by this incline so that all of the sewage can be discharged without leaving any sewage inside the manhole.

In addition, a long recess is formed in the middle portion of the upper invert in the oblique direction, and the end portion connected to the recess is formed in a horizontally curved contact portion downwardly protruding downward to closely contact the bottom of the flange portion of the sewage discharge connection pipe. Make sure that the sewage is discharged smoothly and does not leak inside the manhole.

In addition, a watertight means such as an O-ring is added to a portion of the upper inverted disk that comes into contact with the inner circumferential surface of the manhole so that sewage does not leak to the inner lower end of the manhole.

The malodor trap is connected to the sewage inlet pipe in the interior of the manhole and the lower portion forms a curved portion projecting downwards as a whole.

This curved portion allows the middle to be separated and opened so that dirt accumulated inside can be removed. In order to enable the opening and closing, the odor prevention trap is cut to the left and right sides on the basis of the lowest point of the upper curved portion, and the part connected to the sewage inlet pipe on one side is called a connection part, and the part on which the other side is opened and closed is called an opening part. . The connecting portion and the opening and closing portion is provided with a coupling means such as a hinge (hinge) on the upper side can be opened and closed without being completely separated.

Preferably, the trap operation handle is formed at the upper portion so that a person can open and close the handle by holding the handle.

In addition, the upper portion of the odor prevention trap formed by the upper hinge is attached to the leaf spring or torsion (torsion) spring so that the trap is not opened by the load of the fluid contained in the inside of the upper curved portion.

The semi-circular diaphragm is additionally formed inside the odor prevention trap to prevent odors from flowing back. That is, sewage or waste water is introduced through the sewage inlet connection pipe and falls into the invert through the odor prevention trap and is discharged to the sewage discharge connection pipe. In this process, the curved portion always contains fluid. The fluid contained in this curved portion always maintains a constant level regardless of the inflow of sewage or wastewater. At this time, a space through which air flows is formed in the upper portion of the fluid contained in the curved portion. By forming a diaphragm that can block the portion can block the odor flowing into the upper portion of the fluid contained in the curved portion. The arc part of the upper semicircular diaphragm is connected to the gas odor trap and the horizontal part of the semicircle is formed so as to be submerged at least on the surface of the fluid.

The connection between the odor prevention trap and the sewage inlet pipe is forcibly fitted, or a protrusion is formed on the outer periphery of the trap, and the sewage inlet pipe forms a groove into which the protrusion is inserted, and then the trap is inserted and then turned. It can be fastened, can be fastened as a separate band or connected by bond coupling.
