Description

협잡물 처리기용 드럼스크린{Drum screen of contaminant processing machine}Drum screen of contaminant processing machine

본 발명은 협잡물 처리기용 드럼스크린에 관한 것으로, 좀 더 상세하게는 오폐수 및 하수 등 수처리장에서 하수 및 오 폐수에 포함된 협잡물을 회전하는 드럼스크린에 의해 효율적으로 걸러내어 분리 배출할 수 있도록 하는 협잡물 제거용 드럼스크린에 관한 것이다.The present invention relates to a drum screen for a debris processor, and more specifically, a debris to effectively filter out and discharge the contaminants contained in sewage and sewage wastewater in a water treatment plant such as wastewater and sewage by means of a rotating drum screen. It relates to a drum screen for removal.

통상적으로 정수장 또는 오, 폐수처리장 등 수처리장의 유입시설에 이용되는 협잡물 처리장치의 드럼스크린에 대하여 설명하면,When explaining the drum screen of the contaminant treatment device, which is usually used for inflow facilities of water treatment plants such as water purification plants or wastewater treatment plants,

양측에 위치하는 구동롤러에 의해 회동되도록 드럼스크린이 구비되고 외부로 부터 유입되는 폐수가 폐수공급관을 통해 드럼스크린의 내부에 유입되어 협잡물을 회전하는 드럼에 폐수를 매쉬스크린에 의해 걸러 분리 배출시키도록 구성되어 있다.The drum screen is provided to be rotated by the driving rollers located on both sides, and the wastewater flowing from the outside flows into the drum screen through the wastewater supply pipe so that the wastewater is filtered and discharged by the mesh screen on the drum rotating the contaminants. Consists of.

특히, 드럼플레이트의 둘레에 구비되어 협잡물을 걸러내도록 하는 매쉬스크린은 원통형의 내면에 접촉되도록 위치시킨 상태에서 일정간격을 두고 원형 띠 형상의 웨지바를 부착시키어 매쉬스크린이 드럼플레이트의 내면에 밀착되도록 설치되고 있다.In particular, the mash screen provided around the drum plate to filter out contaminants is installed so that the mesh screen is in close contact with the inner surface of the drum plate by attaching a wedge bar in the shape of a circular band at regular intervals while being positioned to contact the inner surface of the cylinder. Is becoming.

그러나 상기에서 기술한 바와 같이 종래에는 드럼플레아트의 내면에 구비하는 매쉬스크린이 단순히 다수개의 웨지바로 받치도록 구성하고 있어 각 웨지바 사이의 매쉬스크린은 탄력성을 갖지 못하고 느슨해진 상태로 내,외부에서 사용중에 가해지는 압력이나 자중 및 협잡물의 눌림으로 매쉬스크린이 불규칙하게 휘는 변형 현상이 발생되고 있다.However, as described above, conventionally, the mash screen provided on the inner surface of the drum plate is simply configured to be supported by a plurality of wedge bars, and the mash screen between each wedge bar does not have elasticity and is loose from the inside and outside. Deformation phenomenon that the mesh screen bends irregularly is generated due to pressure applied during use, self-weight, and pressing of contaminants.

이러한 매쉬스크린의 변형현상은 협잡물을 걸러내는 과정에서 매쉬스크린에 미세한 이물질이 끼여지면서 폐색되는 것을 외부에서 분사노즐에 의한 여과수의 분사로 이물질을 탈리시키는 세척과정을 수행하게 되는데 이 과정에서 스크린이 불규칙한 변형으로 매쉬스크린 면에 골고루 분사가 이루어지지 못하고 일부 면에 이물질이 탈리되지 못하게 될 뿐만 아니라 매쉬스크린의 내면에 부착된 유기물질들은 쉽게 탈리되지 못하여 체거름효과를 저하시키는 문제점이 있다.In the process of filtering the contaminants, the mesh screen undergoes a washing process that removes foreign substances by spraying filtered water by a spray nozzle from the outside while being blocked while fine foreign matter is stuck in the mesh screen. In this process, the screen is irregular Due to the deformation, the spraying is not evenly distributed on the surface of the mash screen, foreign substances cannot be detached from some surfaces, and organic substances attached to the inner surface of the mash screen cannot be easily detached, thereby deteriorating the sieve effect.

또한, 매쉬스크린과 드럼플레이트의 사이에 틈새가 사용할수록 커져 틈새로 이물질이 끼여지고 이 틈새로 끼워진 이물질은 여과수의 분사로 제거되지 못하는 문제점도 발생하고 있다.In addition, as the gap is used between the mash screen and the drum plate, the larger the gap, the more foreign matter gets stuck in the gap, and the foreign matter stuck in the gap is also prevented from being removed by the injection of filtered water.

또한, 상기 과정에 의해 매쉬스크린에 이물질이 정상적으로 세척되지 못하고 여과효율이 떨어지면 매쉬스크린을 교체하게 되는데 그 공정이 상당히 번거로워 유지관리 보수에 상당한 어려움이 뒤따르고 있다.In addition, when the foreign matter is not normally cleaned in the mash screen by the above process and the filtration efficiency is reduced, the mash screen is replaced. The process is quite cumbersome, and there is considerable difficulty in maintenance and repair.

It comprises a water tank (60).

도 2는 본 발명의 구성을 보인 사시도이고, 도 3은 본 발명의 구성을 보인 단면도이고, 도 4는 본 발명의 요부 구성을 보인 확대도를 나타낸바 이들 도면에 의하여 설명하면,2 is a perspective view showing the configuration of the present invention, FIG. 3 is a cross-sectional view showing the configuration of the present invention, and FIG. 4 is an enlarged view showing the main configuration of the present invention.

상기 드럼스크린부재(40)는 원통형의 둘레 면에 일정간격으로 통공을 형성하는 드럼플레이트(41)와, 상기 드럼플레이트(41)의 외면에 감싸지도록 부착되는 미세 망체 형상의 매쉬스크린(42)으로 구성하고 있다.The drum screen member 40 is a drum plate 41 forming a through hole at regular intervals on a circumferential surface of the cylinder, and a fine mesh-shaped mesh screen 42 attached to be wrapped around the outer surface of the drum plate 41 It is composed.

상기 드럼플레이트(41)의 외면에 서로 대칭하는 위치로 각각 형성하는 압입홈(41a)과, 상기 압입홈(41a)에 끼워져 드럼플레이트(41)의 외면에 구비하는 매쉬스크린(42)을 압입되게 눌러지도록 구비하는 고정플레이트(43)를 체결볼트(44)로 체결하여 구비하여 이루어진다.The press-in grooves 41a respectively formed at positions symmetrical to each other on the outer surface of the drum plate 41 and the mesh screen 42 provided in the outer surface of the drum plate 41 are inserted into the press-in grooves 41a to be press-fitted. It is made by fastening the fixing plate 43 provided to be pressed with a fastening bolt 44.

도 5에서와 같이. 상기 드럼플레이트(41)의 양측단에 중앙부가 소정 직경으로 관통된 마감커버(41b)를 형성하는 반밀폐형으로 형성하여 유입되는 폐수가 매쉬스크린(42)의 폐색 등으로 일부 정체될 때 드럼스크린부재(40)의 내부에 소정의 유량을 담을 수 있도록 하여 안정적인 유량을 확보로 처리장에 걸러지지 않은 폐수가 유출되는 것을 방지할 수 있다.As in Figure 5. The drum screen member when the wastewater flowing into the semi-closed form forming a finishing cover 41b with a central diameter penetrating at both ends of the drum plate 41 is partially blocked due to the obstruction of the mash screen 42 or the like. By allowing a predetermined flow rate to be contained in the interior of the (40), it is possible to prevent the wastewater that is not filtered by the treatment plant from flowing out by securing a stable flow rate.

이와 같은 본 발명에서 드럼플레이트(41)에 매쉬스크린(42)을 결합하는 과정을 살펴보면, Looking at the process of combining the mesh screen 42 to the drum plate 41 in the present invention as described above,

드럼플레이트(41)의 외면에 매쉬스크린(42)을 감싸면서 매쉬스크린(42)의 양단부를 어느 하나의 압입홈(41a) 위치에서 겹치게 한 후 고정플레이트(43)를 압입홈(41a)에 끼워질 수 있도록 위치시키어 체결볼트(44)로 고정플레이트(43)를 압입홈(41a)의 내면에 나사 체결하게 되면 고정플레이트(43)가 압입홈(41a)으로 끼워지는 과정에서 매쉬스크린(42)이 함께 눌러지면 둘레면이 당겨져 매쉬스크린(42)이 드럼플레이트(41)에 밀착된 상태로 고정된다.While wrapping the mesh screen 42 on the outer surface of the drum plate 41, overlap the both ends of the mesh screen 42 at any one press-fit groove 41a position, and then insert the fixing plate 43 into the press-fit groove 41a. When the fixing plate 43 is screwed to the inner surface of the press-in groove 41a by positioning the bolt so that the fastening bolt 44 can be positioned, the mash screen 42 is inserted in the process where the fixing plate 43 is fitted into the press-in groove 41a. When pressed together, the circumferential surface is pulled and the mesh screen 42 is fixed in close contact with the drum plate 41.

그리고 드럼플레이트(41)에 형성한 또 다른 위치에 형성한 압입홈(41a)에 고정플레이트(43)를 체결하면 매쉬스크린(42)은 더욱 둘레가 당겨지게 되어 드럼플레이트(41)의 외면에 매쉬스크린(42)이 변형되지 않고 밀착된 상태를 장기간 유지함으로서 매쉬스크린(42)에 내,외부에서 처리수를 분사할 때 매쉬스크린(42)에 균일한 압력으로 분사가 이루어져 매쉬스크린(42)에 부착된 이물질이 쉽게 탈리되어 매쉬스크린(42)의 여과효율을 증진시키고 장기간 안정적인 여과기능을 수행할 수 있을 뿐만 아니라 매쉬스크린(42)의 사용주기를 증가시킬 수 있는 것이다.And when the fixing plate 43 is fastened to the press-in groove 41a formed in another position formed in the drum plate 41, the mash screen 42 is further pulled around, and the mesh is attached to the outer surface of the drum plate 41. When the screen 42 is not deformed and maintains a close state for a long time, when the treated water is sprayed from the inside and the outside of the mash screen 42, the mash screen 42 is sprayed with a uniform pressure. The attached foreign matter is easily desorbed to improve the filtration efficiency of the mash screen 42 and to perform a stable filtration function for a long time, as well as to increase the use cycle of the mash screen 42.

한편, 드럼플레이트(41)의 양측단에 중앙부가 소정 직경으로 관통된 마감커버(41b)를 형성하는 반밀폐형으로 형성되어 있어 처리장치에 고장이나 매쉬스크린(42)에 많은 폐색이 될 경우 폐수가 원활히 처리되지 못하여 드럼스크린부재(40)내에 어느 정도의 수위까지 예비저장할 수 있고 이를 감지하여 알릴 수 있는 수단을 제공하여 폐수가 오버플러되는 것을 방지할 수 있다.On the other hand, if the central portion at both ends of the drum plate 41 is formed in a semi-hermetic form to form a closed cover 41b with a predetermined diameter, the wastewater is discharged if the treatment device breaks down or the mesh screen 42 becomes obstructed. Since it is not processed smoothly, it can be pre-stored to a certain level in the drum screen member 40 and provides a means to detect and notify the wastewater from being overflowed.

또한, 장기간 사용으로 매쉬스크린(42)의 기능이 저하되어 교체할 경우에는 드럼플레이트(41)의 외면에 체결볼트(44)의 분해로 간편하게 매쉬스크린(42)을 분리하여 교체할 수 있어 유지 보수가 간편하다.In addition, when the function of the mash screen 42 is deteriorated due to long-term use, the mash screen 42 can be easily removed and replaced by disassembling the fastening bolt 44 on the outer surface of the drum plate 41, thereby maintaining Is easy.
