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 contaminants treatment apparatus, and more particularly, to a drum screen contaminant treatment apparatus capable of filtering and removing contaminants contained in sewage and wastewater in a wastewater and sewage treatment plant.

통상적으로 정수장 또는 오, 폐수처리장 등 수처리장의 유입시설에 이용되는 드럼스크린부재 협잡물 처리장치에 대하여 설명하면,In general, description will be given of a drum screen member contaminant treatment device used for inflow facilities of water treatment plants such as water purification plants or wastewater treatment plants

회동되도록 구비하는 드럼스크린에 외부로부터 유입되는 폐수가 폐수 공급라인을 통해 드럼스크린의 내부에 유입시키어 협잡물을 걸러내도록 이루어져 있다.Wastewater flowing from the outside into the drum screen provided to rotate is made to flow into the inside of the drum screen through the wastewater supply line to filter out impurities.

선행기술로 등록실용신안 등록번호 제20-0417966호(공고일자; 2006. 06. 07.) 롤링 회전구조를 갖는 협잡물 제거용 드럼스크린부재으로 제안한 바 있다.As a prior art, it has been proposed as a registered utility model registration number 20-0417966 (announced date; 2006. 06. 07.) as a drum screen member for removing impurities with a rolling rotation 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 of a cylindrical structure with an internal screen is mounted on the upper side of the support frame, and a wastewater supply pipe is introduced into the inner surface of one side of the drum, and the drum is configured to be rotated by a roller drive device, and impurities are discharged at the outlet side of the drum. The hopper is configured.

또한, 드럼스크린의 어느 한측 둘레 외부에 분사관을 구비하고 있다.Further, 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 means that when the wastewater flows into the drum screen through the wastewater supply pipe, the wastewater is discharged downward through the screen, and the impurities caught on the screen are moved by the discharge guide screw and carried 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 closed during use, the filtering function of the screen is significantly deteriorated, and the supplied wastewater cannot escape and is overflowed and the wastewater that cannot remove impurities flows into the treatment plant, which is significant for subsequent processes. It is causing a problem.

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 impurities caught inside the drum screen are gradually moved by the discharge guide screw, there is a problem in that the wastewater cannot be easily filtered due to the interference, and the filtering function is deteriorated.

또, 스크린의 폐색을 줄이기 위하여 외부에서 세척수를 분사하고 있으나 이는 스크린 내면에 밀착된 일부분들이 탈리되지 못하여 스크린의 여과처리능력이 저하되고 처리능력이 불안정한 문제점들이 있다.In addition, in order to reduce clogging of the screen, washing water is sprayed from the outside, but this has problems in that the filtration processing capacity of the screen is deteriorated and the processing capacity is unstable because portions closely adhered to 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 around the drum to filter out impurities is installed so that the screen is in close contact with the inner surface of the drum by attaching a circular band-shaped wedge bar at regular intervals while being placed in contact with the inner surface of the cylinder. Since the screen provided on the inner surface is simply configured to be supported by a number of wedge bars, the screen between each wedge bar does not have elasticity, and the screen between each wedge bar has no elasticity, and a deformation phenomenon occurs in which the screen is partially bent due to pressure, self-weight, and impurities being pressed. Accordingly, there is a problem that impairs the filtering 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 in order to solve the problems presented in the prior art, and the impurities that are filtered by the rotation of the drum screen member in the wastewater and sewage treatment plant are entered into the inside of the drum screen member. To provide a drum mesh screen impurity treatment device that improves the cleaning function of the screen while efficiently disposing of impurities by simultaneously spraying washing water inside and outside the drum screen member while compressing and dewatering with impurities discharging 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 in close contact with the drum by means of press-fitting, preventing deformation of the screen during use and ensuring that the screen is always in close contact with the drum, thus increasing the sieving effect and meshing the screen due to adhesion of organic matter. There is another feature in providing a drum mesh screen for a contaminant handler to suppress clogging.

본 발명은 상기한 목적을 구현하기 위한 해결수단에 대하여 설명하면 다음과 같다.The present invention will be described with respect to a solution for implementing the above object as follows.

And, a treatment water tank for preliminarily storing treated water coming out of the filtration process under the drum screen member, and the impurities that are inserted into the drum screen member and filtered by the mesh screen are collected while being compressed and dehydrated and returned to the outside.
