Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

More particularly, the present invention relates to a sewage odor shielding device, which is connected to the end of a sewage pipe connected to a sewage tank or a manhole, and is opened when sewage flows and is prevented from flowing into the sewage pipe To a sewage odor blocking device.

Generally, a drain pipe for discharging used water is connected to places where drainage is required, for example, a kitchen sink, a toilet sink, and a bathroom toilet. It is moved mainly into a septic tank installed outside the building or a manhole for treating wastewater. Since such a sewage pipe is directly connected to the house along the drain pipe, odor in the septic tank or the manhole often flows into the room.

Conventionally, in order to solve the above problem, a malodor shielding device as shown in Fig. 1, the inflow portion 110 and the discharge portion 130 of the sewage are respectively connected to the sewer pipe, and the sewage introduced into the inflow portion 110 is separated from the residual portion 120, And then discharged through the discharge unit 130. [

Since the residual portion 120 is always filled with sewage, the malodor flowing from the discharge portion 130 is blocked by the sewage remaining in the residual portion 120.

However, the malodor shielding apparatus shown in Fig. 1 has the risk of winter frost due to the water remaining in the remnant 120. In order to connect the drainage pipe 130 formed vertically to the drainage pipe 130 when the sewage water flowing vertically into the inlet portion 110 along the sewage pipe is discharged to the discharge portion 130 through the remaining portion 120, "There is a problem that construction is relatively inconvenient because a separate pipe is required.

On the other hand, Korean Patent Laid-Open Publication No. 2012-0015994 discloses a sewage odor prevention device. The malodor prevention device is configured to drain only when the amount of wastewater drained to the sewage side is equal to or greater than a predetermined amount, and to keep the incision hole of the receiving housing closed when the waste water is not drained. A receiving housing having an incision hole formed in an obliquely downward direction on an upper surface thereof; A rotation cover rotatably installed on the side of the incision hole of the receiving housing; A rotatable coupling portion rotatably coupling the rotatable cover to the receiving housing; And return means for providing an elastic force to the rotary cover.

However, the above-described odor prevention device is installed within a household, and is required for every household in multi-generation houses or apartments, and is required in every place where a kitchen, a bathroom, Lt; / RTI > In addition, since the diameter of the drain pipe is varied, a separate adapter for matching the size with the drain pipe needs to be provided on the rim (seating lip) of the upper opening of the receiving housing. As a result, Is not only relatively difficult and complicated, but also has a problem that only a construction worker can construct and demolish it.

In addition, although the malodor prevention device is currently sold as a product called i-trap ^TM , it is impossible to clean the residue generated at the bottom of the product because it is vertically installed in the drain pipe in the household, So that the product must be replaced frequently.

Korean Patent No. 1159174 also discloses an apparatus for blocking sewage odor and preventing backflow. Wherein the malodor shielding device comprises a body having a through hole, a plate fastening part fixed to a side surface of the body, an open / close plate rotatably connected to the plate fastening part and including a turning part covering the through hole, A support plate protruding in the longitudinal direction, a plate-shaped support portion in the form of a waste space in contact with the rotation portion, and an elastic member composed of a fixed end portion supported by the support plate, the pair of which branches off from the plate support portion.

However, the malodor shielding device is substantially the same as the sewage odor prevention device disclosed in Korean Patent Laid-Open Publication No. 2002-0015994, which has already been mentioned, and is disclosed in Korean Patent Publication No. 2012-0015994 Which has the problem of the odor prevention device of the sewer.

Accordingly, the present inventors have found that, in order to solve these problems of the prior art, the sewage odor shielding device is free from the danger of winter frost, is easy to install, and has excellent odor blocking effect only by installing one or two per multi- And to provide a malodor blocking device which can be used permanently because the product is exposed to the outside and can be cleaned.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The present embodiments and drawings are intended to assist the understanding of the present invention and are not intended to limit the scope of the invention in any way.

2 and 3 are examples of a perspective view of the malodor shielding device of the present invention.

As shown in FIGS. 2 and 3, in an embodiment of the present invention, there is provided a sewage treatment system including (1) an inlet portion connected to a sewage pipe at one side thereof for introducing sewage, and a discharge portion for discharging sewage at the opposite side, (2) a lid part (230) located on the discharge part and preventing odor from entering the body part, and (3) a lid part And a connection part 220 connecting the body part 210 and the lid part 230 and enabling the lid part 230 to be opened and closed, Wherein the inclined angle alpha is 60 to 75 degrees and the lid part 230 is opened by the pushing force of the sewage and returned to the discharge part by gravity.

Body portion

The body portion 210 of the present invention includes an inlet portion connected to the sewage pipe at one side thereof to receive sewage, and a discharge portion for discharging sewage to the opposite side.

The body portion 210 may be made of a polymer material such as stainless steel or PVC (polyvinyl chloride), ABS (acrylonitrile butadiene styrene copolymer), polyethylene, polycarbonate or epoxy, And can be produced by injection molding into a mold. For example, when the sewage pipe is a 100-pi pipe (inner diameter: about 10.8 cm, outer diameter: about 11.5 cm), a 100-pi pipe of the same material may be used as the material of the body part 210.

The thickness of the tube of the body part 210 may be 2 to 6 mm, 3 to 5 mm, or 4 to 5 mm.

As shown in FIGS. 6 and 7, the inflow portion can fit the inner diameter of the inflow portion to the outer diameter of the sewage pipe so as to insert the malodor shield into the sewage pipe. On the contrary, as shown in FIGS. 4 and 5, The outer diameter of the inlet portion may be aligned with the inner diameter of the inlet portion.

The inner diameter of the inflow portion is determined according to the diameter of the sewage pipe. For example, in the case of a sewage pipe having a 100-pi pipe (inner diameter of about 10.8 cm, outer diameter of about 11.5 cm), when the inner diameter of the inlet portion is adjusted to the outer diameter of the sewage pipe, the inner diameter of the inlet portion may be about 11.5 cm, Considering use, it may be 11.6 to 11.7 cm which is slightly larger than this.

The inlet may be connected to the sewer pipe by an adhesive, but preferably the inlet of the body may be connected to the sewer pipe by a rubber packing. When connected by an adhesive, it is not possible to turn the device after inserting the malodor shield into the sewer pipe, which requires considerable accuracy in initial fitting, whereas in the case of being connected by rubber packing, As a result, it is possible to construct by yourself, since the construction is simple.

The discharge portion may be inclined to be inclined with respect to the longitudinal direction of the body portion, and the inclination angle may be 60 to 75 degrees, 62 to 73 degrees, 64 to 70 degrees, or 66 to 67 degrees.

When the inclination angle is more than 60 degrees, the lid can be effectively sealed by gravity, and when the inclination angle is less than 75 degrees, the lid can be opened and closed by the pressure of the weak sewage.

And a connection part 212 for fixing the connection part 220 may be provided at an upper end of the discharge part. The connection portion receiver 212 may be made of the same material as the body portion, adhered to the body portion by an adhesive, and the upper end of the connection portion receiver 212 may be flat.

On the end face of the discharge part, a rubber packing 214 may be provided to closely contact the discharge part and the lid part 230. The rubber packing 214 can be adhered to the end face of the discharge portion by an adhesive.

The lid portion

The lid portion 230 of the present invention is located on the discharge portion and prevents the odor from entering the body portion.

The lid part 230 may be made of a polymer material such as stainless steel or PVC (polyvinyl chloride), ABS (acrylonitrile butadiene styrene copolymer), polyethylene, polycarbonate or epoxy, preferably stainless steel 304 (Wire made of POHANG) 1T (thickness: 1 mm).

The weight of the lid part may vary depending on the diameter of the sewage pipe to be connected, but may be 100 to 160 g, 120 to 140 g, or 130 g when connected to a sewage pipe having a 100-pi pipe (inner diameter of about 10.8 cm).

When the lid part 230 is closed, a bent part 234 may be formed on the rim of the lid part so as to surround the outer part of the discharge part.

The width of the bent portion 234 may be 2 to 7 mm, 3 to 5 mm, 3 to 4 mm, or 3.5 mm.

If the width of the bent portion 234 is 2 mm or more, the discharging portion can be effectively sealed and the folding portion 234 can be easily manufactured. If the width is less than 7 mm, the weight of the covering portion can be less affected. Can be reduced.

The lid part 230 may include a clearance part 232 formed by cutting the bent part 234 at the lower end of the lid part 230. The clearance part 232 facilitates discharge of sewage when the amount of sewage is small.

The gap portion 232 may be 2 to 5 cm, 3 to 4 cm, or 3.3 cm.

When the clearance 232 is 2 cm or more, a small amount of sewage can be effectively discharged. When the clearance is less than 5 cm, the loss of the bent portion 234 can be minimized and the discharge portion can be effectively sealed.

Connection

The connection part 220 of the present invention is formed at the upper end of the discharge part to connect the body part 210 and the lid part 230 and to open and close the lid part 230.

The connecting portion 220 may be a generally used stainless steel material, or may be a polymer material such as other metal or PVC, ABS, polyethylene, polycarbonate or epoxy. As shown in FIG. 2, Lt; / RTI >

The connection unit 220 includes a body connecting member 224 connected to the body 210 and a lid connecting member 226 connected to the lid 230.

In an embodiment of the present invention, the body connecting member 224 may be connected to the connection base 212 by an adhesive or welding, and may be connected by a screw 222. In addition, the lid part connecting member 226 may be connected to the lid part 230 by welding, adhesive, or screw.

In addition, in the embodiment of the present invention, there is no connecting part support 212, and the body connecting member 224 and the body part 210 are injected as one component, and the lid connecting member 226 and the lid part The body part connecting member 224 and the lid part connecting member 226 may be fitted to each other to form the connecting part 220 (refer to FIGS. 4 to 7).

The connection portion opens the discharge port by the pressure of the sewage when the sewage is discharged, and closes the discharge port by the gravity when the sewage is not discharged.

The sewage odor isolation device of the present invention is installed in a sewer pipe parallel to the ground. Specifically, the sewage pipe is horizontally connected to the end of the sewage pipe connected to the inside of the septic tank or the manhole, and is opened when the sewage flows and is closed when the sewage does not flow to prevent the odor from being introduced into the sewage pipe. The term "sewer pipe parallel to the ground" as used herein means a sewer pipe which is completely parallel to the ground, but also refers to a sewer pipe slightly inclined from the ground, for example, less than 1 degree, less than 3 degrees, less than 5 degrees, Or less than or equal to 30 degrees. In practice, the sewer pipes installed in the landscape are often slightly sloped to the ground so that sewage flows easily.

Since the sewage odor interrupter of the present invention is installed in a sewer pipe parallel to the ground, the lid portion is opened by the pushing force of the sewage and returns to the discharge portion by gravity. Because of this action, it is important to set the inclination angle [alpha] of the discharge portion with respect to the longitudinal direction of the body portion.

The sewage is moved to the water tank in the septic tank or the manhole through the sewage odor interrupter of the present invention. Accordingly, the sewage odor-blocking device of the present invention is easily exposed to the outside and can be easily cleaned, and can be attached and detached by the rubber packing provided in the inflow portion, which facilitates installation and cleaning.

As described above, in the sewage odor interrupter of the present invention, when the sewage flows, the lid part 230 is opened, and when the sewage does not flow, the lid part 230 is closed to prevent the odor from being introduced into the sewer pipe .

Unlike the malodor blocking device shown in Fig. 1, there is no risk of winter frost because sewage does not remain in the malodor blocking device.

In addition, the construction of the malodor screening apparatus shown in Fig. 1 requires a separate "L" -shaped pipe, which is inconvenient and difficult to implement. On the other hand, in the malodor screening apparatus of the present invention, It can be completed simply by inserting it by using the rubber packing formed on the base material.

In addition, since the malodor shielding device of the present invention is connected to the end of the sewage pipe connected to the septic tank or the manhole, unlike the invention disclosed in Korean Patent Laid-Open Publication No. 2002-0015994 and Korean Patent No. 1159174, Only 1 or 2 per installation shows excellent odor blocking effect.

In addition, since the malodor shielding device of the present invention can be completed only by inserting the sewage pipe protruding into the septic tank or the manhole by using the rubber packing formed at the inflow portion of the body portion, the construction is completed. Thus, Korean Patent Publication No. 2002-0015994, Unlike the 1159174, there is no need for separate sealing work, and it is easy for the customer to construct and demolish.

In addition, the malodor shielding device of the present invention is exposed to the inside of a septic tank or a manhole and can be cleaned and used permanently.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that various modifications and changes may be made.
