Abstract

PURPOSE: An improved sewage sludge scraper is provided which smoothly scrapes sludge by modifying the sludge scraper for collecting solids (sludge) precipitated on initial sedimentation basin, final sedimentation basin and thickening tank into the center of them during sewage disposal process of sewage terminal disposal plant. CONSTITUTION: The improved sewage sludge scraper comprises an improved sludge scraper part comprising a rubber part(1) contacted with concrete surface, a stainless steel flat bar(3) the upper part of which is formed of rubber and rivetted to a stainless steel plate, a guide plate(2) fabricated of stainless steel plate to vertically move the stainless steel flat bar(3), a stainless steel rectangular pipe having dimensions of 55x25x25/2t(4) welded to both ends of the guide plate(2), and a stainless steel rectangular pipe having dimensions of 1900x25x20/2t(5) welded to the stainless steel rectangular pipe having dimensions of 55x25x25/2t(4), wherein the improved sludge scraper part is welded to an existing sludge facility, three lower spots of the stainless steel flat bar(3) and three central spots of the guide plate(2) are connected by springs, and the stainless steel flat bar(3) and guide plate(2) connected by springs are vertically movable to improve close adhering property between the rubber part and the bottom surface of sedimentation basin.

Description

하수슬러지수집기 개선{omitted}Improved sewage sludge collector {omitted}

본 발명은 하수종말처리장의 최초침전지.최종침전지.농축조의 슬러지수집기를 개선하여 하수처리를 원활히하고, 슬러지수집기의 사용년한을 영구히하기 위함이다.The present invention is to improve the sludge collector of the first settler, the final settler and the concentration tank of the sewage terminal treatment plant to facilitate the sewage treatment and to permanently use the sludge collector.

기존 슬러지수집기는 스크레이퍼(고무)마모등로 1년에 한번이상 교체나 정비를 하기위해 지를 비워야 했고,Existing sludge collector had to empty the paper for replacement or maintenance at least once a year due to scraper (rubber) wear, etc.

침전지나 농축조 구조물의 콘크리트 구조물의 Level차로 침강된 오니가 중앙으로 모이지 않아 오니의 펌핑이 원활히 되지않고 침전된 오니가 부폐하여 수면으로 부상하는등 하수처리에 부작용을 초례하였음.Due to the level difference between concrete structures of sedimentation basin and thickening tank structure, sedimentary sludge did not collect in the center, so sludge was not pumped smoothly and sedimented sludge was decayed and floated to the surface.

슬러지수집기의 스크레이퍼 크기는 각 처리장마다 지의 크기가 상이함에 따라 그 곳에 맞추어 제작설치.The scraper size of the sludge collector is manufactured and installed according to the size of the paper in each treatment plant.

침전지나 농축조의 슬러지수집기의 사용년한을 반 영구적으로 하기위해서는 물속에 잠겨있는 철구조물등을 녹이 슬지않는 스테인리스강등으로 교체하여야되고,In order to semi-permanently use the sludge collector of the sedimentation basin or thickener tank, the steel structure submerged in water must be replaced with stainless steel which does not rust.

지의 콘크리트바닥 Level차가 심한곳에는 재시공하고,Re-install in the place where the level difference of concrete floor is severe

슬러지수집기의 구동부 감속기 윤활유교환(1회/년)이나 보충, 중앙구동식의 베어링,주변구동식의 베어링.바퀴등을 내마모성이 좋은제품으로 교환해주어야한다.Drive part of sludge collector Reducer lubricant replacement (once / year) or replacement, central drive bearing, peripheral drive bearing, wheel, etc. should be replaced with good wear resistance.

도 1은 기존 슬러지수집기의 단면도1 is a cross-sectional view of a conventional sludge collector

도 2는 슬러지수집기의 개선부분 단면도,평면도2 is a partial cross-sectional view of the improved sludge collector, top view

도 3은 최종침전조의 단면도,평면도3 is a cross-sectional view of the final settling tank, top view

도면 2의 ①은 콘크리트면과 닿은 고무, ③는 고무부분의 상부를 스테인리스강판과 리벳이음, ②는 ③을 상하로 움직이게 하는 가이드판으로 스테인리스판으로 제작, ②의 양끝단 부분은 ④의 55×25×25/2t 스테인리스 사각파이프와 용접이음하고 ④와⑤(1900×25×20/2t)를 용접이음한후 기존 슬러지설비와 용접이음.In Figure 2, ① is the rubber in contact with the concrete surface, ③ is the upper part of the stainless steel plate and rivet joint, ② is the guide plate which moves ③ up and down, and is made of stainless steel plate, and both ends of ② are 55 × Welded joint with 25 × 25 / 2t stainless steel square pipe and welded ④ and ⑤ (1900 × 25 × 20 / 2t), then welded joint with existing sludge equipment.

③의 하부 3개소와 ②의 중앙 3개소는 스프링으로 연결시키고 고무와 지의 바닥면의 밀착성을 좋게하기위해 상하로 움직일수 있게하였다.The lower 3 places of ③ and the middle 3 places of ② were connected by springs and moved up and down to improve the adhesion between rubber and the bottom of the paper.

이로인해 지의 콘크리트면의 Level차이나 고무의 마모에 따른 슬러지 수집능력저하를 개선하여 오니의 부패로인한 수질악화를 개선.As a result, the sludge collection capacity is reduced due to the level difference between the concrete surface of the land and the wear of rubber, thereby improving the water quality caused by sludge decay.

지를 비워서 슬러지수집기를 정비함으로써 정비후 재가동시 침전지나 농축조에서 하수처리에 작용하던 미생물이 사멸함으로써 정상적인 하수처리를 위해 미생물증식에 필요한 약품등의 비용과 그 기간동안(수일)의 수질오염등을 예방하고,Sludge collectors are emptied to prevent sludge collection and microorganisms used in sewage treatment in thickening tanks. and,

반영구적으로 사용함에 따른 처리장운영유지비를 절감Reduction of plant operation and maintenance costs due to semi-permanent use

Claims (1)

○. 슬러지 수집기의 가동으로 지의 콘크리트 면과 닿는 고무가 마모되는데 이 고무(다른 재질도 포함)의 마모량 만큼 아래로 내려오게 하는 방식○. The operation of the sludge collector causes the rubber to contact the concrete surface of the ground, which wears down by the amount of wear of the rubber (including other materials). ○. 하수종말처리장 뿐만 아니라 분뇨처리장, 폐수처리장 등 수처리와 관련된 모든 설비에 적용한다.○. It is applied to all facilities related to water treatment, such as sewage treatment plant, sewage treatment plant and wastewater treatment plant.
