Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rainwater disposal apparatus,

The present invention relates to an early storm sewer rainwater disposal apparatus, and more particularly, to an initial storm water stormwater disposal apparatus which removes initial contaminants containing foreign matter by non-motor force and feeds clean purified water through second- And a rainwater treatment apparatus.

Water crisis is coming due to depletion of water resources due to global warming, fluctuation of water resources by region and intensification of pollution, and there is a possibility that the water shortage problem will become more serious and the value of rainwater is getting attention.

Rainwater utilization facilities are growing nationwide, and are expanding beyond existing legal facilities.

The rainwater excluding the foreign substances contained in the initial rainwater is clean water which does not require sterilization or disinfection. It is not generally used as drinking water and is widely used as cleaning water, landscape water, fire water, toilet water, It is emerging as a good alternative for. Many technologies have been developed to effectively utilize and utilize rainwater in accordance with the demands of the times, and the following problems related to conventional technologies related to the method of excluding early rain are as follows.

The method of treating the initial rainwater containing various bodies of insects such as dead bodies, leaves, and dusts accumulated on the surface of the rainwater house includes a method of directly excluding the initial rainwater from the storm water system, And a method of treating it after filtration and other processes. In the latter case, a separate storage facility and space are required.

As a method for excluding foreign matter contained in the initial rainfall, separation by screen, filtration apparatus using soybean gravel, sand, etc. and vortexing apparatus using centrifugal force are used, and these apparatuses are clogged by foreign substances during rainfall In addition, it has a disadvantage in that it is necessary to remove foreign matter at the end of rainfall.

The "Act on Promotion and Support of Reuse of Water" stipulates the scale of the rainwater utilization facility by the capacity exceeding the scale of the rainwater catchment area multiplied by 0.05 m, and the exclusion quantity of the initial rainwater containing the foreign matter is also defined. As a method for determining the amount of exclusion of early storms, there are a control method by the time when the control valve is operated when a predetermined time passes after sensing the rainfall, a method of controlling the amount of rainfall by operating the control valve after measuring a certain amount using a rain gauge And the like are used, and all of these methods require power. On the other hand, due to the irregular characteristics of rainfall, even if a certain time has elapsed, it may be difficult to collect relatively good quality rainwater if the rainfall is insufficient. Therefore, it is preferable to use the rainfall control method rather than the time control method.

The following terms are defined in consideration of the functions of the present invention, and these may be changed according to the intention of the user, the operator, or the like. Therefore, the definition should be based on the contents throughout this specification.

&Lt; Example 1 >

As shown in Figs. 1 to 3, in the initial excellent exuding rainwater disposal apparatus using the rotatable screening trough according to the present embodiment, the inflow portion of the rainwater and the discharge portion of the discharge water are arranged at the same height, And a specific configuration is that the housing 10, the screen 20 for removing an initial pollutant source and foreign matter, the vertical screen for filtering the rainwater passing through the screen 20 and supplying the purified water And a typical screening container (30).

The housing 10 is divided into a housing main body 11 and a housing cover 12 for manufacturing and maintenance.

The housing main body 11 is preferably provided with an inlet portion 13, a discharge portion 14, and a purified water discharge portion 15, which are open and communicated with each other.

The inlet portion 13 is a tube inlet portion to receive rainwater as a portion into which the rainwater flows, and to guide the rainwater into the housing main body 11. [

The discharge unit 14 functions to discharge an initial polluted source and foreign matter (fallen leaves, etc.) filtered in the housing main body 11 to a river or the like, and a pipe can be constituted together.

The inflow section 13 and the discharge section 14 are formed at the same height so that rainwater can be filtered without a height difference.

The purified water discharging portion 15 is a hole that opens to the bottom portion of the bottom portion of the housing main body 11 and supplies the purified water filtered by the rotatable screening tube 30 to a storage tank or the like, A joint portion is formed.

The present embodiment is characterized in that the inflow portion 13 is formed along the tangential direction at the edge portion of the housing main body 11 so that the rainwater flows in the tangential direction and the discharge portion 14 is formed along the tangential direction It does not.

The housing cover 12 has a structure that opens and closes an upper opening of the housing main body 11 and is assembled to be detachable through, for example, a bolt and a nut.

The screen 20 filters the initial contaminants from the rainwater flowing through the inflow section 13, filters foreign substances (litters, etc.) other than the initial contaminants, and initializes the initial And is formed in a plate shape in which a pollutant blocking portion 21 is formed and a filtration portion 22 is formed for passage of rainwater. The screen 20 is not necessarily applied, but is selectively applied. The screen 20 is also separated for cleaning the foreign substance between the screen 20 and the rotatable screening tube 30, and the like.

The initial pollutant blocking portion 21 is in the form of a void free of holes that can not pass through rainwater in order to raise the purification rate.

In order to enhance the initial pollutant blocking effect by the initial pollutant blocking portion 21, a backflow preventing jig may protrude laterally on the initial pollutant blocking portion 21. [ The backflow prevention jig is protruded in the lateral direction on the outer circumferential surface of the screen 20 so that initial contaminants flowing along the bottom of the housing and the initial contaminant blocking portion 21 of the screen 20 flow backward .

The filtration unit 22 has a hole through which the foreign matter can not pass but the rainwater passes through, for example, a form of a perforated plate, a shape of a mesh net, and the like.

Such an initial pollutant blocking portion 21 and the filtration portion 22 can be made of a single plate material, for example, by a method of perforating a hole in only a part of a single plate material, or a non- And mesh networks.

The screen 20 is disposed at a position corresponding to the outlet of the inflow section 13 for filtering the rainwater flowing in the inflow section 13 and spaced apart from the periphery of the rotatable screening tube 30 by a predetermined space, (For example, semicircular) so as to maintain the inflow of the rainwater in the eccentric direction. That is, the housing body 11 may be formed with a semicircular convex breech-block mounting portion for eccentric mounting of the rotatable screen 30.

The screen 20 can be fitted to a rail 16 (formed between a pair of projections or grooves) formed on both sides of the inner circumferential surface of the housing main body 11.

The rail 16 may be formed on the inner circumferential surface of the housing main body 11 as a whole along the vertical direction, or may be formed in the form of a dot at a part thereof.

The rotary screening tank 30 has a cylindrical shape having a space therein and has a plurality of screening holes for filtering rainwater flowing from the outside through the screen 20 so as to have a diameter that covers the purified water discharging portion 15 . The sorting ball can be both a piercing type and a mesh type.

The rotatable screening cylinder 30 is preferably mounted to rotate inside the housing 10 through the flow of rainwater.

Preferably, the rotatable screen 30 is formed with a shaft 31 for rotation thereon. The shaft 31 passes through the housing lid 12 and is fixed to the housing lid 12 by a nut or the like so that the shaft 31 is separated from the housing body 11 naturally by separation of the housing lid 12, The operation is convenient for.

The shaft 31 is formed on the upper portion of the rotary type screening tube 30 opposite to the purified water discharging portion 15 so that it does not interfere with the discharge of purified water and has an advantage of easy assembly. (30).

The rotatable screen 30 is provided with a plurality of vanes 34 for natural rotation by the flow of rainwater.

The vane 34 is preferably a concave shape so as to effectively receive the water pressure of the rainwater. For example, the vane 34 is a curved plate material, and a plurality of the vane 34 are arranged at equal intervals along the circumferential direction.

In addition, an initial pollutant blocking portion 35 may be selectively formed at the bottom of the rotatable screening container 30. [ The initial pollutant blocking portion 35 has the same function as the initial pollutant blocking portion 21 of the screen 20 as a hole-free form, thereby maximizing the filtering effect of the initial pollutant.

The rotatable screen 30 may have a structure in which the ceiling is clogged. According to this structure, the rainwater flowing into the rotatable screen 30 can be prevented from leaking out through the ceiling.

The operation of the initial storm sewer rainwater disposal apparatus using the rotary type screening tube according to the present embodiment is as follows.

1. Rainwater inflow

The rainwater flows into the housing 10 through the inlet portion 13.

2. Primary filtration by screen.

In the initial stage, the rainwater and the initial pollutant are mixed, and the rainwater and the initial pollutant introduced into the housing 10 pass through the screen 20. In this process, since the initial contaminants have a property of sinking on the floor, they can not pass through the screen 20 by the initial contaminant blocking portion 21 of the screen 20 and are discharged through the outlet portion 14.

The rainwater above the initial pollutant blocking portion 21 passes through the filtration portion 22 of the screen 20 and foreign matter having a size larger than that of the filtration portion 22 can not pass through the screen 20, (14). &Lt; / RTI >

On the other hand, the rainwater passes through the hole of the filtration part 22 of the screen 20 and flows toward the rotatable screening container 30. At this time, the foreign matter does not pass through the screening hole of the rotatable screening container 30, However, the rainwater passes through the sorting hole of the rotary type screening tube 30, flows into the rotary type screening tube 30, and then is discharged through the purified water discharging portion 15 at the bottom. At this time, some rainwater is discharged through the discharge portion 14.

Since the rainwater flows in the tangential direction of the rotatable screen 30 and the vanes 34 are present in the periphery of the rotatable screen 30, the rotatable screen 30 smoothly rotates, Since the screening tube 30 is rotated, the filtration efficiency of the foreign substance is high, and a vortex phenomenon is generated to discharge the purified water at a high speed.

As shown in FIG. 4, in this embodiment, an elastic material (such as rubber) is used to reduce the friction between the bottom of the rotatable screening tube 30 and the bottom surface of the housing main body 11 while preventing the penetration of foreign substances and the leakage of rainwater. The skirt 35 may be constructed. The skirt 35 is mounted on the bottom of the rotatable screening tube 30 along the circumferential direction and contacts the bottom surface of the housing main body 11 through elastic deformation to prevent a gap from being created. When the skirt 35 is worn, the skirt 35 can be used by replacing only the skirt 35. For example, the skirt 35 is detachably assembled through a bolt, a nut, a piece, or the like.

5 and 6, the brush 40 can be applied as a cleaning means for cleaning the rotatable screening cylinder 30. The brush 40 can be used as a cleaning means for cleaning the rotatable screening cylinder 30, as shown in Figs.

Preferably, the brush 40 is provided in the periphery of the rotatable screen 30 as a rod to scratch the surface of the rotatable screen 30 to remove foreign substances. A method of scraping the surface, and a method of moving the scraper in contact with the surface of the rotatable screen 30 during cleaning are possible. In the latter case, the housing cover 12 is vertically penetrated and forms a rail in the direction of getting closer to or away from the rotatable screen 30, and the brush 40 is vertically arranged in the interior of the housing 10 The brush 40 is separated from the rotatable screen 30 so that the handle 41 is rotated at the time of cleaning. And the brush 40 is moved to the rotary type screen 30 to clean the rotary type screen 30 so that the bristles touch the surface of the rotary type screen 30, The valve 42 may be configured to block the purified water discharge unit 15 so that the foreign matter removed from the purified water discharge unit 15 is not discharged to the purified water discharge unit 15. The valve 42 may be a butterfly valve or the like.

The rotatable screening tank 30 is constructed in the same manner as the first embodiment, and the rainwater passing through the screen 20 is secondarily sorted and then guided to the purified water discharge unit 15. [

The dispersing portion 23, the wall portion 24, and the discharge inducing portion 25 may be integrally formed or separated from each other. In the latter case, the dispersing portion 23, the wall portion 24, and the discharge inducing portion 25 are divided into three parts, that is, two parts (for example, the dispersing part 23 alone, (25) can be integrally formed.

The foreign substances in the initial rainwater flowing into the housing 10 through the inlet 13 are dispersed right and left through the dispersing portion 23 and then flows along the wall portion 24 to be discharged through the discharge inducing portion 25 Of course, the initial pollutant source bypasses the rotary type screen 30 through the initial pollutant cutoff unit 21 and is discharged.

The primary filtered rainwater that has passed through the screen 20 is filtered through the rotary type screening tube 30 in a secondary order and discharged to the purified water discharge unit 15 as purified water. In this process, the rotatable screen 30 is rotated by the primary filtration rainwater, and the rainwater forms a vortex so that the quick discharge of the purified water is achieved.
