Description

Drainage with sedimentation tank and odor backflow prevention function

The present invention relates to a catchment for preventing the backflow of odor, in particular, to prevent the backflow of odor, and also to filter out filth (small particles of soil, sand or gravel, etc.) that is introduced together when filthy water and rainwater are introduced. The present invention relates to a sedimentation tank and a drain having a odor counterflow prevention function to enable the odor counterflow prevention device to operate smoothly.

In hot weather, such as summer, many odors occur in places such as catch basins. This is because the odor generated by decay of the sewage and sediment settled in the lower part of the catchment and the sewage flows back to the catchment. For this reason, in order to prevent the backflow of odor, a odor backflow prevention device is installed in a catchment.

Looking at the structure of the conventional malodor backflow prevention device as shown in Figure 1 in the lower portion of the drainage cap 11 is formed in the central portion of the body 12 formed in the upper and lower strait type to form a drain hole 13 and using the center of gravity principle A damper 14 is provided to open and close the drain hole 13 automatically. That is, the damper 14 is composed of a heavy weight portion 15 on one side of the plate size enough to open and close the drain hole 13, so that the center of gravity of the damper 14 is directed to the wedge portion 15 side. The hinge 16 is coupled to the body 12.

With this structure, when water flows into the water collecting port 10a, the water is collected toward the drain hole 13, and when the weight of the collected water is heavier than the weight portion 15 of the damper 14, the damper 14 rotates to drain water. By opening (13), the incoming sewage is drained. When the drainage of the sewage is completed, the damper 14 is rotated in the reverse direction by the center of gravity of the weight portion 15 to close the drainage hole 13. Therefore, the water is opened when the water is drained, and since the water is kept closed after the water is drained, the odor from the water collecting port 10a does not flow back.

In addition, in the case of the catchment port 10b having a horizontal flow of sewage as shown in FIG. 2, there is also a structure in which the damper 19 for blocking the inlet port 18 is hinged to the upper end of the inlet port 18.

This structure is such that when the sewage flows into the inlet 18, the damper 19 is automatically opened by the water pressure, and when the inflow of sewage is completed, it is automatically closed by its own weight.

However, when the sewage passes through the malodor counterflow prevention device, various wastes are not only caught in the drain hole or the damper of the malodor backflow prevention device, but also, as time passes, they accumulate and prevent the damper from blocking the drain hole properly. The phenomenon of backflow through the gap between the damper and the drain hole occurs, and the sewage is clogged because it is impossible to collect the soil in a timely manner due to the odor backflow prevention device. This resulted in a nucleus in which sewage was paralyzed. In particular, in winter, the odor prevention device is installed in the upper part of the catchment, so snow or water freezes, causing paralysis.

In addition, the catchment structure shown in Figure 2 is the sediment and sewage that was introduced with the sewage is accumulated and deposited on the floor and eventually the damper does not work properly remains in the open state. Because of this, there is a disadvantage that the odor flows back through the gap.

Because of these drawbacks, the odor reflux prevention device must be cleaned frequently or caught, and the odor reflux prevention function must be removed from time to time by removing the sediment and sediment accumulated in the catchment.

This phenomenon is caused by rainwater or sewage flowing into the catchment, without first filtering the soil, contaminants, etc., and then passing the malodor counterflow prevention device and then entering the catchment so that the dirt accumulates. If rainwater or sewage is passed through the settling tank to remove the dirt before passing through the malodorous backflow prevention device, the dirt will not get stuck or caught in the malodorous backflow prevention device.

In addition, if a certain period of time passes, the sediment deposited on the bottom of the catchment should be cleaned. At this time, the dirt cannot be seen due to the odor blocking device so that it cannot be cleaned in a timely manner. This is inconvenient, and also because the catch port has a variety of sizes, the odor reflux prevention device has to be manufactured according to the specifications of the various catch ports, respectively, it costs a lot of cost and has a disadvantage of difficult management because it must be stored and managed according to the standard.

Therefore, the present invention allows the filthy water to pass the odor reflux prevention device after passing through the sedimentation tank so that the function of the odor regurgitation prevention device can be maintained and managed well over time, and at the same time, the dirt removal operation can be performed quickly and easily. The purpose is to make it.

In addition, the present invention is a odor countercurrent prevention device of one standard to be installed universally in the catchment of various standards and to install in the middle to maintain its function without freezing in winter due to warmth and geothermal heat.

The present invention for achieving the above object, in the catchment port having a malodor backflow prevention device is installed by the damper is automatically opened and closed by the center of gravity, the upper periphery of the catch port is formed to install a sedimentation tank, the catchment tank, By forming a step on the inner central portion of the odor countercurrent prevention device is installed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a cross-sectional view showing the structure of the catchment backflow prevention apparatus according to the present invention, the catchment 20 of the present invention, as shown in the upper end step 22 is formed on the upper inner side, the lower end step 24 on the inner peripheral surface of the central portion; ), The upper step (22) is settled in the sedimentation tank (30), the lower step (24) formed in the center portion was installed malodor backflow prevention device (40).

The needle tank 30 has a basket-like flange 31 seated on the upper end 22 at the upper circumference thereof, and a plurality of cutout holes 32 are formed at the upper side thereof so that the sewage overflows. The handle is not shown in the figure is formed to facilitate the removal of the sedimentation tank 30 from the water collecting port 20 when cleaning the dirt.

In addition, the bad smell backflow prevention device 40 is a known device, the damper is automatically opened and closed by the center of gravity on both sides of the body 41, the flange 42 is formed so as to be seated on the lower end 24 of the catchment 20 around the periphery 44 is hinge 46 coupled. At this time, the two dampers 44 are inclined toward the center portion, and the ends thereof are in contact with each other. In addition, the weight portion 45 is formed at the rear end of each damper 44, which is hinged to the body 41 so that the center of gravity is directed to the weight portion 45 side.

When sewage is introduced by this structure, the sediment, such as heavy and bulky dirt or soil, sand and small boulder, is introduced into the sedimentation tank 30 and overflowed into the plurality of cutout holes 32 formed as the upper side. After the impurities are filtered out, it is introduced into the malodor backflow prevention device (40). The introduced sewage falls to the upper portion of the damper 44, and the dampers 44 are opened by the weight thereof so that the sewage is drained to the lower portion of the catchment port 20. When the sewage passes through the damper 44, the water collecting port 20 is blocked by rotating back to the original position by the weight 45 installed at the rear end. At this time, since the sewage is already filtered in the sedimentation tank 30, the sewage is not caught or deposited on the malodor counterflow prevention device 40.

In addition, when periodically cleaning the dirt of the catch 20 to remove the sedimentation tank 30 from the catch 20 by simply using a handle installed on the upper part of the catch and clean it again, it is very convenient because the cleaning is simply completed again. . And odor backflow prevention device 40 may be occasionally cleaned.

In addition, when rain falls a lot, such as during the rainy season, a large amount of rainwater flows in. At this time, when a large amount of rainwater flows into the sedimentation tank 30, the sediment deposited in the lower part of the sedimentation tank 30 is swept away by the water of rainwater. The phenomenon which comes out to the notch hole 32 of 30 generate | occur | produces. This is because the dropping distance of rainwater flowing into the sedimentation tank is high, causing dirt to be lifted by the impact and exiting the cutout hole 32 together with the overflowed sewage. Therefore, the rainwater guide plate 47 may be installed at the upper portion of the catchment 20 to naturally reduce the dropping distance while leading the rainwater to the sedimentation tank 30 naturally. The structure of the rainwater guide plate 47 has a flange that is seated on the water collecting port 20, the adapter frame 60 or the tubular body 50, which will be described later, or the tubular body 50, and passes through the rainwater therein. The inner end of the hole is formed to be inclined downward. Therefore, when rainwater flows in, the rainwater is naturally induced by the inclined surface to the sedimentation tank 30, and since the lower end of the hole is formed lower toward the sedimentation tank 30, the dropping distance can be further reduced, thereby reducing the drop impact of rainwater. Such excellent guide plate 47 is to be used only during the rainy season during the rainy season, if the rainy season passes after the collection of the sedimentation tank (30).

In addition, the odor backflow prevention device of the catchment of the present invention may be installed in a structure as shown in FIG.

That is, Figure 4 is an exploded perspective view showing the structure of the catchment backflow prevention apparatus according to another embodiment of the present invention, Figure 5 is an assembled cross-sectional view of the catchment backflow prevention apparatus of Figure 4, as shown in the sedimentation tank (30) Odor backflow prevention device 40 may be configured as a single assembly.

The adapter frame 60 penetrates to the center portion in a size similar to the inlet of the cylinder 50, and a stepped portion 62 is formed around the inner end of the through hole so that the flange 51 of the cylinder 50 is formed. Is configured to be seated. The adapter frame 60 is manufactured in various sizes for each catch 20 having a different size according to the drainage capacity. However, the size of the holes to be constant to install a cylinder 50 consisting of a single size, but to configure the number of through-holes for each size to maintain the drainage capacity. Therefore, it is possible to install it universally in each water collecting port having a different size with the cylinder 50 manufactured in the same size. In addition, such a structure can be equally applied to the structure in which the sedimentation tank 30 and the malodor backflow prevention device 40 are separately installed in the catchment port 20.

By this structure, the sedimentation tank 30 and the bad smell counterflow prevention device 40 are produced in one standard, and only the adapter frame 60 is produced according to the size of the water collecting port 20. Since the device of the present invention can be installed, the maximum effect can be obtained at a low cost.

In addition, as shown in FIG. 6a, a portion in close contact with the bottom of the manhole cover 26 is cut around the adapter frame 60a to form a groove 61a so as not to receive a load of the lid 26. This is to prevent the adapter frame 60a from being damaged by the dynamic load from the vehicle or the like passing through the upper portion of the lid 26 together with the load of the heavy lid 26. Even when the lid 26 is seated on the stepped portion 22 of the 70, the lower end of the lid 26 is positioned between the grooves 61a of the adapter frame 60a as shown in FIG. 6B. ) Or dynamic loads such as a vehicle passing through the lid 26 are transmitted directly to the step 22. Therefore, even if the adapter flange (60a) is formed of a synthetic resin that is not impacting, but not metal, the function can be sufficiently exhibited, and its life can be extended for a long time.

Also, as shown in FIG. 7A, the odor reflux prevention device 90 may be installed in the catchment 70 installed in a structure in which the inner wall surface 72 is vertically narrowed.
