Description

드럼스크린 협잡물 처리장치{Drum screen contaminant processing equipment}Drum screen contaminant processing equipment

본 발명은 드럼스크린 협잡물 처리장치에 관한 것으로, 좀 더 상세하게는 오폐수 및 하수처리장에서 하수 및 오 폐수에 포함된 협잡물을 걸러내어 제거할 수 있도록 하는 드럼스크린 협잡물 처리장치에 관한 것이다.The present invention relates to a drum screen contaminant treatment apparatus, and more particularly, to a drum screen contaminant treatment apparatus to filter and remove contaminants contained in sewage and sewage wastewater in a wastewater and sewage treatment plant.

통상적으로 정수장 또는 오, 폐수처리장 등 수처리장의 유입시설에 이용되는 드럼스크린부재 협잡물 처리장치에 대하여 설명하면,The drum screen member contaminant treatment device, which is usually used for inflow facilities of water treatment plants such as water purification plants or wastewater treatment plants, will be described.

회동되도록 구비하는 드럼스크린에 외부로부터 유입되는 폐수가 폐수 공급라인을 통해 드럼스크린의 내부에 유입시키어 협잡물을 걸러내도록 이루어져 있다.Wastewater flowing from the outside to the drum screen provided to be rotated is made to filter the contaminants by flowing into the drum screen through the wastewater supply line.

선행기술로 등록실용신안 등록번호 제20-0417966호(공고일자; 2006. 06. 07.) 롤링 회전구조를 갖는 협잡물 제거용 드럼스크린부재으로 제안한 바 있다.As a prior art, registration utility model registration number 20-0417966 (announcement date; 2006. 06. 07.) has been proposed as a drum screen member for removing contaminants having a rolling rotating structure.

상기 선행기술에 대하여 살펴보면,Looking at the prior art,

받침프레임의 상측에 스크린이 내설된 원통형구조의 드럼이 장착되고, 상기 드럼의 일측 내면에 폐수공급관이 유입되도록 이루어지며, 상기 드럼은 롤러구동장치에 의하여 회동되도록 구성되고 드럼의 출구측에 협잡물 배출호퍼가 구성되어 있다.A drum having a cylindrical structure with a screen installed on the upper side of the supporting frame is mounted, and a waste water supply pipe is introduced into one inner surface of the drum, and the drum is configured to rotate by a roller driving device and discharges contaminants to the outlet side of the drum. The hopper is configured.

또한, 드럼스크린의 어느 한측 둘레 외부에 분사관을 구비하고 있다.In addition, an injection pipe is provided outside the periphery of either side of the drum screen.

이는 폐수공급관을 통해 드럼스크린의 내부에 유입되면 폐수는 스크린을 통해 하방으로 빠져나가고 스크린에 걸려지는 협잡물은 배출유도스크류에 의해 이동하면서 배출호퍼를 통해 외부로 반출되도록 하고 있다.This allows the wastewater to be discharged downward through the screen when it enters the interior of the drum screen through the wastewater supply pipe, and the contaminants caught on the screen are moved by the discharge induction screw to be taken out through the discharge hopper.

그러나 상기 종래기술은 사용과정에서 스크린의 간극이 폐색시 스크린의 여과기능이 현저하게 저하되고 그에 따라 공급되는 폐수가 빠져나가지 못하고 오버플러되어 협잡물을 제거하지 못한 폐수가 처리장으로 유입되어 후속 공정에 상당한 문제를 발생시키고 있다.However, in the prior art, when the gap of the screen is occluded in the process of use, the filtering function of the screen is remarkably deteriorated, and accordingly, the wastewater that has not been removed and overflowed because the supplied wastewater does not escape is introduced into the treatment plant, which is considerable for subsequent processes. It is causing problems.

또, 드럼스크린 내부에 걸려지는 협잡물이 배출 유도스크류에 의해 서서히 이동되기 때문에 이로 인한 방해로 폐수가 쉽게 여과되지 못하여 여과처리 기능이 저하되는 문제점이 있다.In addition, since the contaminants hanging inside the drum screen are gradually moved by the discharge induction screw, there is a problem in that the filtration treatment function is deteriorated because the wastewater cannot be easily filtered due to the interference.

또, 스크린의 폐색을 줄이기 위하여 외부에서 세척수를 분사하고 있으나 이는 스크린 내면에 밀착된 일부분들이 탈리되지 못하여 스크린의 여과처리능력이 저하되고 처리능력이 불안정한 문제점들이 있다.Also, in order to reduce the occlusion of the screen, the washing water is sprayed from the outside, but this has a problem that the filtration processing capacity of the screen is deteriorated and the processing capacity is unstable because parts close to the inner surface of the screen cannot be removed.

또, 드럼의 둘레에 구비되어 협잡물을 걸러내도록 하는 스크린은 원통형의 내면에 접촉되도록 위치시킨 상태에서 일정간격을 두고 원형 띠 형상의 웨지바를 부착시키어 스크린이 드럼의 내면에 밀착되도록 설치되어 있어 드럼의 내면에 구비하는 스크린이 단순히 다수개의 웨지바로 받치도록 구성하고 있어 각 웨지바의 사이의 스크린은 탄력성을 갖지 못하고 느슨해진 상태로 압력이나 자중 및 협잡물의 눌림으로 스크린이 일부 불규칙하게 휘는 변형 현상이 발생됨에 따라 스크린의 여과기능을 저해하는 문제점이 있다.In addition, the screen provided on the periphery of the drum to filter out contaminants is placed so as to be in contact with the inner surface of the cylinder, and at regular intervals, a wedge bar in the shape of a circular band is attached to the screen so that the screen is installed in close contact with the inner surface of the drum. Since the screen provided on the inner surface is simply configured to be supported by a plurality of wedge bars, the screen between each wedge bar does not have elasticity and is loosened, resulting in some irregular deformation of the screen due to pressure, self-weight, and pressing of contaminants. Accordingly, there is a problem of inhibiting the filtration function of the screen.

본 발명은 상기 종래기술에 제시한 문제점들을 해결하기 위하여 제안된 것으로, 오폐수 및 하수처리장에서 하수 및 오 폐수에 포함된 협잡물을 드럼스크린부재의 회동으로 걸러지는 협잡물을 드럼스크린부재의 내부에 진입되는 협잡물 배출수단으로 압착 탈수하여 배출되도록 하면서 드럼스크린부재에 내 외부로 동시에 세척수를 분사되도록 하여 협잡물의 처리를 효율적으로 수행하면서 스크린의 세척기능을 향상시키도록 하는 드럼 매쉬스크린 협잡물 처리장치를 제공함에 있다.The present invention has been proposed to solve the problems presented in the prior art, in the waste water and sewage treatment plant to enter the inside of the drum screen member to filter the contaminants contained in sewage and sewage wastewater by the rotation of the drum screen member It is to provide a drum mash screen contaminant processing apparatus that improves the washing function of the screen while efficiently performing the treatment of contaminants by simultaneously spraying washing water to the drum screen member to the drum screen member while being discharged by squeezing and dewatering with the contaminant discharge means. .

또, 드럼의 외면 둘레에 스크린을 압입수단에 의하여 드럼에 탄력적으로 밀착되도록 구성하여 사용중에 스크린의 변형을 방지하면서 항시 스크린이 드럼에 밀착되도록 하므로 체거름 효과를 증가시키고 유기물부착으로 인한 스크린의 매쉬 폐색을 억제하도록 하는 협잡물 처리기용 드럼 매쉬스크린을 제공함에 또 다른 특징이 있다.In addition, the screen around the outer surface of the drum is configured to be resiliently in close contact with the drum by means of press-fitting means, so that the screen is always in close contact with the drum while preventing deformation of the screen during use, thus increasing the sieving effect and mashing the screen due to adhesion of organic matter. Another feature is to provide a drum mash screen for a contaminant processor to suppress occlusion.

상기 드럼스크린부재(50)의 내부로 내입되어 매쉬스크린(52)에 의해 걸러지는 협잡물을 압착 탈수하면서 수거하여 외부로 반송하도록 하는 협잡물 스크루배출수단(70)과,A contaminant screw discharge means (70) for collecting and transporting the contaminants filtered into the drum screen member (50) and filtered by the mesh screen (52) while being dehydrated and transported to the outside.

상기 드럼플레이트(51)의 출구 측에 오버플러되는 폐수를 회수할 수 있도록 구비하는 오버플러슈트(55)와,And the overflow chute (55) provided to recover the wastewater that is overflowed to the outlet side of the drum plate (51),

상기 드럼스크린부재(50)에 매쉬스크린(52)을 내 외부로 동시에 처리수를 분사되도록 분사노즐(81,91)을 갖는 분사공급라인(80,90)를 구비한 것을 포함하여 이루어진다.The drum screen member 50 comprises a mesh screen 52 having an injection supply line 80 and 90 having spray nozzles 81 and 91 to simultaneously spray treated water to the inside and outside.

상기 협잡물 스크루배출수단(70)은 드럼스크린부재(50)의 내부에 전방부가 진입되면서 소정각도 경사지게 위치하도록 구성되어 상부가 개방된 이송관로(71)내에 구동부(72)에 의해 회전하는 이송스크루(73)가 유입되는 협잡물을 압착 탈수하면서 외부로 이송하여 그 후단에 형성한 협잡물 배출슈트(74)를 통해 외부로 배출되도록 한다.The contaminant screw discharge means 70 is configured to be positioned at a predetermined angle while the front portion enters the interior of the drum screen member 50, and the transfer screw rotates by the drive unit 72 in the transfer pipe 71 where the upper part is opened ( 73) is transported to the outside while squeezing and dehydrating the inflowing contaminants to be discharged to the outside through the contaminant discharge chute 74 formed at the rear end.

이와 같은 본 발명에 대하여 상호 작용상태를 설명한다.The interaction state will be described with respect to the present invention.

유입되는 폐수가 폐수공급관(40)을 통해 구동부(20)에 의해 회전하는 드럼스크린부재(50)의 내부에 유입되면 매쉬스크린(52)을 통해 여과되면서 하방에 구비하는 처리수조(60)로 처리수가 배출되고 걸러지는 협잡물은 드럼스크린부재(50)의 내부에 모아지면서 길이방향으로 구비하는 협잡물 스크루배출수단(70)의 이송관로(71)에 형성된 유입구(71a)를 통해 유입된다.When the inflowing wastewater flows into the drum screen member 50 rotated by the driving unit 20 through the wastewater supply pipe 40, it is filtered through the mash screen 52 and treated with a treatment tank 60 provided below. The contaminants that are discharged and filtered are collected in the drum screen member 50 and introduced through the inlet 71a formed in the transport pipe 71 of the contaminant screw discharge means 70 provided in the longitudinal direction.

그리고 이송관로(71)로 유입되는 협잡물은 이송스크루(73)를 통해 이송하는 과정에서 압축과정을 거쳐 나오는 폐수는 다시 드럼스크린부재(50)로 유입되면서 이송되어 후방부에 위치한 협잡물 배출슈트(74)를 통해 외부로 배출된다.In addition, the contaminants flowing into the conveying pipe 71 are transported through the conveying screw 73, and the wastewater coming through the compression process is again transferred to the drum screen member 50 while being transported to the contaminant discharge chute located at the rear part 74 ) To the outside.

상기 폐수처리과정에서 폐수의 처리가 원활하지 않는 경우 별도의 콘트롤장치(도면 미표현)의 감지신호에 따라 간헐적으로 내,외부에 구비하는 분사노즐(81,91)에서 드럼스크린부재(50)의 내부 및 외부에 처리수를 분사하여 매쉬스크린(52)에 걸려진 각종 유기물 등 이물질 등을 제거하여 체거름 기능을 정상적으로 유지시키어 준다.When the wastewater is not smoothly treated in the wastewater treatment process, the drum screen member 50 is intermittently provided in the injection nozzles 81 and 91 provided intermittently and externally according to a detection signal of a separate control device (not shown). By spraying treated water inside and outside, it removes various organic substances, such as caught in the mash screen 52, to maintain the sieve function normally.

한편, 드럼플레이트(51)의 양측단에 중앙부가 소정 직경으로 관통된 마감커버(51b)를 형성하는 반밀폐형으로 형성되어 있어 처리장치에 고장이나 매쉬스크린(52)에 많은 폐색이 될 경우 폐수가 원활히 처리되지 못하여 드럼스크린부재(50)내에 어느 정도의 수위까지 예비저장할 수 있고 이를 감지하여 알릴 수 있는 수단을 제공하여 폐수가 오버플러되는 것을 방지할 수 있으며, 만약 오버플러시 드럼플레이트(51)의 후방에 구비하는 오버플러슈트(53)를 통해 오버플러되는 폐수를 회수할 수 있는 것이다.On the other hand, since the central portion at both ends of the drum plate 51 is formed in a semi-hermetic shape to form a finishing cover 51b penetrated by a predetermined diameter, when a failure occurs in the treatment device or if the mesh screen 52 is obstructed, wastewater is discharged. Since it is not processed smoothly, it can be pre-stored to a certain level in the drum screen member 50 and provides a means to detect and notify it to prevent the wastewater from being overflowed, and if the overflow of the drum plate 51 is It is possible to recover wastewater that is overflowed through the overflow chute (53) provided at the rear.

이상과 같이 본 발명은 드럼스크린부재(50)의 회동으로 걸러지는 협잡물을 드럼스크린부재(50)의 내부에 진입되는 협잡물 스크루배출수단(70)에 의해 압축 탈수 배출되도록 하여 후속처리 및 유지관리성을 확보할 수 있고, 드럼플레이트(51)에 매쉬스크린(52)을 밀착 고정하므로 체거름 효과의 증가 및 유기물 부착으로 인한 매쉬 폐색을 억제할 수 있고 드럼스크린부재(50)에 내 외부로 동시에 세척수를 분사되도록 하여 매쉬스크린(52)의 사용주기를 증가시킬 수 있는 것이다.As described above, the present invention allows the debris filtered by the rotation of the drum screen member 50 to be compressed and dehydrated by the contaminant screw discharge means 70 entering the inside of the drum screen member 50 for subsequent processing and maintenance. Can be secured, and the mesh screen 52 is tightly fixed to the drum plate 51, so that the sieve effect can be increased and the clogging of the mesh due to the attachment of organic matter can be suppressed, and the washing water can be simultaneously washed in and out on the drum screen member 50. It is possible to increase the use cycle of the mash screen 52 by spraying.
