However, the following examples are provided to enable those skilled in the art to fully understand the present invention, but the scope of the present invention is not limited by the embodiments described below.

도 1은 본 발명에 의한 콘크리트 재활용수 농도 측정 및 보정용 계량장치의 개략도이다. 도 1에서 보는 바와 같이, 본 발명에 의한 콘크리트 재활용수 농도 측정 및 보정용 계량장치는 본체(100), 재활용수공급및회수부(200), 무게측정부(300), 수위측정부(400), 세척부(500), 제어부(미도시)를 포함하고 있다. 이하 각 부분에 대하여 설명한다.
1 is a schematic diagram of a measuring device for measuring and correcting the concentration of concrete recycled water according to the present invention. As shown in FIG. 1, the concrete recycling water concentration measurement and correction device according to the present invention includes amain body 100, a recycling water supply andrecovery unit 200, aweight measurement unit 300, a waterlevel measurement unit 400, Thewashing unit 500 and a control unit (not shown) are included. Each part is demonstrated below.

본체(100)는 폐콘크리트 재생과정에서 발생한 재활용수가 유입되어 저장되는 공간으로서, 하부에는 재활용수가 배출될 수 있는 방출구(110)를 구비하고 있다. 방출구(110)에는 재활용수의 방출을 조절하기 위한 방출밸브(120)가 설치되어 있다. 본체(100)의 형상에 대해서는 특별한 제한은 없으나, 바람직하게 본체(100)는 원통형상 또는 사각형상을 가진다.
Themain body 100 is a space in which recycled water generated during the recycling of waste concrete is introduced and stored therein, and has adischarge port 110 through which the recycled water can be discharged. Thedischarge port 110 is provided with a discharge valve 120 for controlling the discharge of recycled water. The shape of themain body 100 is not particularly limited, but preferably, themain body 100 has a cylindrical shape or a rectangular shape.

재활용수공급및회수부(200)는 재활용수공급관(210), 재활용수회수관(215) 및 유입관(220)을 포함한다.The recycled water supply andrecovery unit 200 includes a recycledwater supply pipe 210, a recycled water recovery pipe 215, and aninflow pipe 220.

재활용수공급관(210)은 본체(100)에 폐콘크리트 재생과정에서 발생한 재활용수를 유입시키기 위하여 재활용수저장탱크(미도시)와 후술하는 유입관(220)을 연결하는 부분으로서, 일단은 재활용수저장탱크에 연결되고, 타단은 재활용수회수관(215)과 유입관(220)에 연결되어 있다.The recycledwater supply pipe 210 is a part connecting the recycled water storage tank (not shown) and theinlet pipe 220 to be described later in order to introduce the recycled water generated during the waste concrete recycling process into themain body 100, and the recycled water is once recycled. It is connected to the storage tank, and the other end is connected to the recycling recovery pipe 215 and theinlet pipe 220.

재활용수회수관(215)은 재활용수가 회수되어 다시 재활용수저장탱크로 유입될 수 있도록 재활용수공급관(210)과 재활용수저장탱크를 연결하는 배관이다.The recycled water collection pipe 215 is a pipe connecting the recycledwater supply pipe 210 and the recycled water storage tank so that the recycled water is recovered and flowed back into the recycled water storage tank.

유입관(220)은 재활용수공급관(210)에 연결되어서 재활용수 저장탱크로부터 이송되는 재활용수를 본체(100)의 내부로 유입시키는 역할을 한다. 이를 위하여 유입관(220)은 상단부는 재활용수공급관(210)과 연결되어 있고, 하단부는 본체(100)의 하단부 근처까지 연장되는 것이 바람직하다. 유입관(220)의 하단부에는 다수의 분사공(225)이 형성되어 있는데, 이는 재활용수의 갑작스런 유입 충격으로 인하여 본체에 충격이 가해지는 것을 방지하고, 재활용수가 본체(100)내에서 비산되는 것을 방지하기 위한 것이다. 즉, 재활용수는 유입관(220)의 하부에 형성된 다수의 분사공(225)을 통하여 본체(100)내로 유입되면서 재활용수가 비산되는 것이 방지된다.Theinlet pipe 220 is connected to the recyclewater supply pipe 210 and serves to introduce the recycled water transferred from the recycled water storage tank into thebody 100. To this end, theinlet pipe 220 is connected to the recycledwater supply pipe 210, the upper end is preferably extended to the lower end of themain body 100. A plurality ofinjection holes 225 are formed at the lower end of theinflow pipe 220, which prevents the shock from being applied to the main body due to the sudden inflow of the recycled water and prevents the recycled water from being scattered in themain body 100. It is to prevent. That is, the recycled water is introduced into themain body 100 through the plurality ofinjection holes 225 formed in the lower portion of theinlet pipe 220, and the recycled water is prevented from scattering.

한편 유입관(220)의 상단부에는 유입관(220)으로 유입되는 재활용수의 양을 정확하게 제어하기 위하여 직경이 큰 주유입관(221)과 직경이 작은 보조유입관(222)으로 구성되어 있으며, 주유입관(221)과 보조유입관(222)에는 각각 계량밸브(223,224)가 설치된다. 본체(100)에 재활용수를 채울 경우에 초반에는 직경이 큰 주유입관(221)과 보조유입관(222)을 통하여 재활용수를 본체(100)내로 신속하게 유입시키다가, 후반에는 직경이 작은 보조유입관(222)만을 통하여 재활용수를 유입시켜서 본체(100)에 유입되는 재활용수의 양을 정확하게 조절하게 된다. 보조유입관(222)으로의 전환은 본체(100)에 유입시키고자 하는 재활용수의 90%가 유입된 시점이 바람직하다. 이는 재활용수의 유입시간과 유입되는 양의 정확성을 고려한 것이다.
On the other hand, the upper end of theinlet pipe 220 is composed of a largediameter inlet pipe 221 and a smalldiameter inlet pipe 222 in order to accurately control the amount of recycled water flowing into theinlet pipe 220,Metering valves 223 and 224 are installed in theinlet pipe 221 and theauxiliary inlet pipe 222, respectively. When themain body 100 is filled with recycled water, the recycled water is rapidly introduced into themain body 100 through themain inlet pipe 221 and theauxiliary inlet pipe 222 having a large diameter, and then, the secondary part having a small diameter in the latter part. The recycled water is introduced only through theinlet pipe 222 to accurately adjust the amount of recycled water flowing into themain body 100. Switching to theauxiliary inlet pipe 222 is preferably a time point 90% of the recycled water to be introduced into themain body 100 is introduced. This takes into account the inflow time of recycled water and the accuracy of the amount introduced.

한편 유입관(220)이 연결된 후단의 재활용수회수관(215)의 최상부에는 통기공(230)이 부착되어 있다. 통기공(230)은 재활용수회수관(215)의 상부로 연결된 배관으로서, 통기공(230)에는 통기공(230)을 개폐시키며 반대방향으로 유체의 흐름을 통제하는 역지밸브(231)가 부착되어 있다. 재활용수공급관(210)을 통하여 주유입관(221)과 보조유입관(222)을 거처 재활용수가 본체(100)로 이송중일 때에는 통기공(230)에 부착된 역지밸브(231)는 열려, 재활용수회수관(215)을 통한 재활용수의 회수가 중단된다. 통기공(230)은 사이폰 현상에 의하여 재활용수회수관(215)에 계속적으로 재활용수가 흐르는 것을 방지하기 위하여 역지밸브(231)를 통하여 자연적으로 재활용수회수관(215)내의 진공을 파괴하는 역할을 한다.

When the recycled water is transferred to themain body 100 via themain inlet pipe 221 and theauxiliary inlet pipe 222 through the recyclewater supply pipe 210, thecheck valve 231 attached to thevent hole 230 is opened to recycle water. Recovery of the recycled water through the recovery pipe 215 is stopped. Thevent 230 serves to break down the vacuum in the recycle collection tube 215 naturally through thecheck valve 231 in order to prevent the recycle water from continuously flowing to the recycling collection tube 215 due to the siphon phenomenon. Do it.

한편 재활용수공급관(210)에는 재활용수의 이송 및 공급을 원활하게 하기 위한 재활용수이송펌프(미도시)와 재활용수의 흐름을 제어하기 위한 밸브(미도시)가 추가로 설치되어 있다.
On the other hand, the recycledwater supply pipe 210 is further provided with a recycled water transfer pump (not shown) to facilitate the transfer and supply of recycled water and a valve (not shown) for controlling the flow of the recycled water.

다음으로 본 발명에 의한 콘크리트 재활용수 농도 측정 및 보정용 계량장치의 운전방법에 대하여 설명한다.Next, the operation method of the concrete recycling water concentration measurement and correction meter for the present invention will be described.

먼저 재활용수저장탱크 내부에 수용되어 있던 재활용수는 펌프에 의하여 재활용수공급관(210)을 통하여 재활용수저장탱크로부터 유출된다. 재활용수공급관(210)으로 유입된 재활용수는 유입관(220)을 통하여 본체(100)로 이송된다. 처음에는 주유입관(221)과 보조유입관(222)을 통하여 본체(100)로 이송되다가 이송의 거의 마칠 시점에는 주유입관(221)이 닫히고, 보조유입관(222) 만으로 본체(100)로 이송된다. 본체(100)에 재활용수가 유입되는 시점에 통기공(230)에 부착된 역지밸브(231)가 자동으로 열리면서 재활용수회수관(215) 내의 진공이 파괴되고어 본체로의 공급을 원활하게 하며 보조유입관(222)을 통한 재활용수의 정밀 계량에도 영향을 주지 않게 된다.
First, the recycled water contained in the recycled water storage tank flows out of the recycled water storage tank through the recycledwater supply pipe 210 by a pump. The recycled water introduced into the recycledwater supply pipe 210 is transferred to themain body 100 through theinlet pipe 220. Initially, themain inlet pipe 221 and theauxiliary inlet pipe 222 are transferred to themain body 100, and at the end of the transfer, themain inlet pipe 221 is closed, and theauxiliary inlet pipe 222 is transferred to themain body 100 only. do. When the recycled water flows into themain body 100, thecheck valve 231 attached to theair vent 230 is automatically opened and the vacuum in the recycled water recovery pipe 215 is destroyed, thereby smoothly supplying the main body to themain body 100. It does not affect the precise metering of the recycled water through theinlet pipe 222.

무게 측정값으로 설정된 본체(100)로의 재활용수의 유입이 완료된 후에 재활용수의 수위가 안정되기를 기다렸다가, 수위측정부(400)와 무게측정부(300)를 이용하여 본체(100) 내의 재활용수의 수위와 무게를 측정하고, 측정된 결과를 이용하여 제어부에서 재활용수의 농도 및 보충하여야 할 청수의 양을 계산하게 된다.
After the inflow of the recycled water to themain body 100 set as the weight measurement is completed, the water level of the recycled water is waited to be stabilized, and then the level of the recycled water in themain body 100 using the waterlevel measuring unit 400 and theweight measuring unit 300. The water level and weight are measured, and the measured results are used to calculate the concentration of recycled water and the amount of fresh water to be replenished.

다음으로 본체(100) 하부의 방출구(110)가 개방이 되면서 본체(100) 내의 재활용수는 외부로 방출된다. 재활용수의 방출이 90%정도 완료되면 본체(100) 내부의 세척을 실시하게 된다. 재활용수가 본체(100)로 유입된 상태에서는 수위측정부(400)의 보호관(420)이 하부로 완전히 이동된 상태로 그 내부의 수위측정수단(410)을 보호하게 된다. 세척이 시작되면 청수이송펌프(510)가 작동하게 되고, 유량계(530)를 통하여 세척부(500)로 이송되는 청수의 양을 측정하게 된다. 이 때 세척에 사용되는 청수의 양은 상기 제어부에서 계산된 보충되어야 할 청수의 양으로서, 세척과정에서 사용된 청수는 방출구(110)를 통하여 먼저 방출된 재활용수와 혼합이 되고, 이로서 재활용수의 슬러지 농도가 원하는 대로 일정하게 유지시킨다.
Next, as thedischarge port 110 in the lower portion of themain body 100 is opened, the recycled water in themain body 100 is discharged to the outside. When the discharge of the recycled water is completed by about 90% is performed to the inside of themain body 100. In the state where the recycled water flows into themain body 100, theprotection pipe 420 of the waterlevel measuring unit 400 is completely moved downward to protect the water level measuring means 410 therein. When the washing is started, the freshwater transfer pump 510 is operated, and the amount of fresh water transferred to thewashing unit 500 through theflow meter 530 is measured. At this time, the amount of fresh water used for washing is the amount of fresh water to be recalculated by the control unit, and the fresh water used in the washing process is mixed with the recycled water first discharged through thedischarge port 110, and thus The sludge concentration is kept constant as desired.

도 2는 본 발명에 의한 세척부의 운전중 이동상황을 도시한 개략도로서, 본체에 재활용수가 유입된 상태에서는 도 2에서 점선으로 표시된 상태로서 보호관과 분사노즐이 위치하나, 본체 내부의 세척시에는 분사노즐이 상하로 이동하게 되고 어느 순간에는 도 2에서 실선으로 표시된 상태로서 보호관과 분사노즐이 위치하게 된다.Figure 2 is a schematic diagram showing the movement of the washing unit during operation according to the present invention, the protective tube and the injection nozzle is located as a dotted line in FIG. The nozzle moves up and down, and at some point, the protection tube and the injection nozzle are positioned as indicated by the solid line in FIG. 2.
