본 출원인의 대한민국 특허출원 제 2003-80163호(2003년 11월 13일 출원)에 "여과장치"가 소개되어 있다.Korean Patent Application No. 2003-80163 (filed Nov. 13, 2003) of the present applicant has introduced "filtration device".

상기 여과장치는 원통형의 하우징에 배치된 원통형의 금속필터에 의해 상기 하우징이 내부챔버와 외부챔버로 구분되고, 상기 하우징의 좌측단에 엔드 커버가 장착되고, 상기 하우징의 우측단에 메인 플랜지 커버가 장착되고, 상기 하우징의 내부챔버에 스크류가 배치되어 상기 스크류가 금속필터의 안쪽면에 부착된 부유물질(슬러지)을 금속필터의 우측단으로 밀어내고, 상기 스크류가 풀리로 부터 동력을 전달받는 샤프트에 장착되어 샤프트의 회전에 의해 작동되고, 상기 메인 플랜지 커버의 내부에 슬러지 배출압력조절수단이 장착되어 스크류에 의한 슬러지 배출압력이 슬러지 배출압력조절수단의 탄성력보다 크게 되면 슬러지가 메인 플랜지 커버로 배출되고, 상기 금속필터의 외측에 에어분사장치가 배치되어 상기 에어분사장치에서 분사되는 압축공기에 의해 금속필터가 연속적으로 역세되는 것을 특징으로 한다.The filtering device is characterized in that the housing is divided into an inner chamber and an outer chamber by a cylindrical metal filter disposed in a cylindrical housing, and an end cover is mounted on the left end of the housing, and a main flange cover is provided on the right end of the housing. And a screw disposed in the inner chamber of the housing to push the suspended solids (sludge) attached to the inner surface of the metal filter to the right end of the metal filter, and the screw receives power from the pulley. And the sludge discharge pressure adjusting means is mounted inside the main flange cover so that the sludge discharged to the main flange cover when the sludge discharge pressure by the screw is greater than the elastic force of the sludge discharge pressure adjusting means. And an air spraying device is disposed outside the metal filter and sprayed from the air spraying device. Axis characterized in that the metal filter by backwashing air continuously.

그러나, 상기 여과장치는 스크류에 의해 오수에 포함된 부유물질(슬러지)의 압축이 이루어지기 때문에, 자흡력이 없어 여과장치로 오폐수를 공급할 수 있는 별도의 펌프가 요구되고, 초기 작동시 오페수에 포함된 슬러지를 압축하지 못하는 단점이 있으며, 금속필터를 역세하기 위해 에어분사장치가 내장되어야 하기 때문에 구조가 복잡한 단점이 있다. However, since the filtration device is compressed by the suspended solids (sludge) contained in the sewage by the screw, a separate pump for supplying the waste water to the filtration device is not necessary because of the self-sufficiency, and when the initial operation There is a disadvantage of not compressing the included sludge, and the structure is complicated because the air injection device must be built in to backwash the metal filter.

따라서, 본 발명의 목적은 원통형 필터의 내부에 배치된 임펠러의 회전에 의해 자흡력이 발생하며, 여과압력이 충분히 발생하고, 별도의 에어분사장치가 없어 도 역세가 가능한 농축여과장치를 제공하는 것이다.Accordingly, an object of the present invention is to provide a concentrated filtration device capable of backwashing without generating a self-sufficiency by the rotation of the impeller disposed inside the cylindrical filter, sufficiently generating a filtration pressure, and without a separate air spraying device. .
