Description

오폐수처리장치용 스크린 {Sreen for separating waste}Screen for Wastewater Treatment System {Sreen for separating waste}

본 발명은 취수, 배수, 중계펌프장 등 각종 펌프장과 하수, 오수, 폐수처리장등에 스크린을 장착하여 유입수가 스크린을 통과할 때 유속에 의해 처리장으로 유입되는 유입수중에 포함된 여러가지 부유물 및 협잡물을 유입수와 분리하여 걸러내는 오폐수처리장치용 스크린에 관한 것으로, 이 스크린을 FRP(Fiberglass Reinforced Plastics)로 제작함으로써 강하고, 가벼울 뿐만 아니라, 내식 내열성이 우수한 오폐수처리장치용 스크린에 관한 것이다.The present invention is equipped with a screen in various pumping stations, such as intake, drainage, relay pumping station, sewage, sewage, wastewater treatment plant, etc., when the influent flows through the screen, the various influents and contaminants contained in the influent flowing into the treatment plant by the flow rate is separated from the influent. The present invention relates to a screen for a wastewater treatment device to be filtered out, and to a screen for a wastewater treatment device which is not only strong and light by producing FRP (Fiberglass Reinforced Plastics), but also having excellent corrosion resistance and heat resistance.

일반적으로 FRP(Fiberglass Reinforced Plastics)는 유리섬유를 주보강재로 하여 불포화 포리에스터 수지를 함침 가공한 복합 구조재로서 내산성, 내알카리성, 내식성이 우수하고, 비중이 철의 약1/5, 강도가 철의 약1/3로 가볍고 튼튼하기 때문에 제작, 설치, 운반등이 훨씬 용이하며, 열변형율이 낮다. 또한, 전기절연성이 우수하여 전기를 전혀 통하지 않기 때문에 전기접합단자부의 봉입용 등에 적합하고, 설계, 가공이 어떠한 형태이든 자유롭고 간편하며, 접착성이 강하기 때문에 타 재질과의 혼성이 용이한 장점이 있다.In general, FRP (Fiberglass Reinforced Plastics) is a composite structural material impregnated with unsaturated polyester resin with glass fiber as the main reinforcing material. It is about 1/3 of light and durable, so it is much easier to manufacture, install and transport, and has a low thermal strain rate. In addition, since it has excellent electrical insulation and does not conduct electricity at all, it is suitable for encapsulation of the electrical connection terminal part, and is free and simple in any form and design. .

산업이 발달함에 따라 각종 펌프장 및 각종 처리장의 유입수 중에는 각종 찌꺼기, 불순물, 부유물 및 각기 다른 크기와 종류의 협잡물이 다량으로 포함되어 유입되고 있는 실정이다. 특히 집중호우 및 홍수시에는 빗물과 함께 떠내려온 각종 협잡물이 취수펌프장의 취수구 및 배수펌프장의 유수지로 유입된다. 이렇게 유입수에 섞여 유입되는 협잡물을 빨리 제거하지 않으면, 수로를 범람시키고, 각종 펌프장에서 펌프의 막힘 등 각종 문제를 유발시킨다. 따라서, 종래에는 이러한 협잡물을 유입수 중에서 확실하게 분리하기 위해서 금속으로 제작된 스크린을 설치하는 것이 일반적이었다. 이렇게 스크린을 설치하여 협잡물을 유입수와 분리한 후, 분리된 협잡물은 신속하게 스크린에서 제거하여야 스크린의 효율을 기대할 수 있다.As the industry develops, various inflows of impurities, impurities, suspended solids, and contaminants of different sizes and types are introduced into the influent of various pumping stations and various treatment plants. In particular, during heavy rains and floods, various contaminants floated with rainwater flow into the intakes of the intake pumping stations and the reservoirs of the drainage pumping stations. In this way, if the contaminants mixed with the inflow water are not removed quickly, the water channel is flooded, causing various problems such as clogging of the pump at various pump stations. Therefore, in the past, it was common to install a screen made of metal in order to reliably separate such contaminants from the influent. After the screen is installed and the impurities are separated from the influent, the separated impurities are quickly removed from the screen so that the efficiency of the screen can be expected.

이러한 오폐수처리장치용 스크린은 도 1에서 도시하는 바와 같이,웨지(Wedge)형상으로 길게 형성된 다수개의 스크린바(1)를 앞뒤가 뚫린 사각형상의 지지틀(2)에 소정간격으로 용접한 것이 사용되었는데, 이는 스크린바(1)를 지지틀(2)에 하나하나 용접해야 하는 불편함이 있었으며, 스크린바(1)의 간격을 일정하게 용접하기가 까다로운 문제점이 있다. 또한 그 무게가 무거워 제작작업이 불편할 뿐만 아니라 스크린의 운반, 설치가 매우 불편한 문제점이 있다.As shown in FIG. 1, a screen for wastewater treatment apparatus is used by welding a plurality of screen bars 1 formed long in a wedge shape to a rectangular support frame 2 having a front and rear drilled at predetermined intervals. This has been an inconvenience to weld the screen bar 1 to the support frame 2 one by one, there is a problem that it is difficult to constantly weld the interval of the screen bar (1). In addition, the weight is heavy, as well as inconvenient production work, there is a problem that the transport, installation of the screen is very uncomfortable.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 스크린을 FRP로 제작하여 스크린의 중량이 가벼워지고, 강도는 유지하면서 가공성과 내식성이 좋은 효과가 있으며, 종래 용접으로 스크린바를 고정하던것을 접착제를 이용하여 고정시킴으로써 제작에 소요되는 인력과 시간이 절감되는 오폐수처리장치용 스크린을 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, the screen is made of FRP to lighten the weight of the screen, while maintaining the strength and workability and corrosion resistance is good effect, fixing the screen bar by conventional welding adhesive The purpose of the present invention is to provide a screen for a wastewater treatment apparatus, which reduces manpower and time required for manufacturing by fixing it.

또한, 오폐수속에 섞여있는 각종 협잡물을 걸르기 위한 스크린바의 간격조절과 설치작업이 용이하며 신속한 오폐수처리장치용 스크린을 제공하는데에도 그 목적이 있는 것이다.In addition, it is easy to adjust the intervals and installation of the screen bar to filter various kinds of contaminants mixed in the waste water, and also to provide a screen for a waste water treatment device quickly.
