Abstract

The present invention relates to a sand selection machine including a drum screen having net holes precisely selecting sand, and a driving apparatus driving to rotate a drum screen. According to the apparatus for preventing net clogging of a sand sorting machine, a rail, on which a roller guiding a rubber scraper moves, is installed on the edge plane of one end or both ends where net holes of the drum screen are not formed, and at least four strike inducing protrusions are installed on the rail. If the rubber scraper including a net clogging prevention striker and the inducing roller automatically wipe out the drum while moving on the rail without power by rotation of the screen drum, the rubber scraper successively strikes the screen by using the falling height difference of the empty surface while the roller rides on strike inducing protrusions and turns over so that sand attached to the inner surface and holes of the screen is effectively shaken off to solve the net clogging. The inclined side of a right-angled triangle of the strike inducing protrusion is arranged in the rotational direction of the drum screen, and the orthogonal side is arranged in the rotational opposite direction of the drum screen.

Description

토사선별장치의 망막힘 방지장치{APPARATUS FOR PREVENTING CLOGGING OF SCREEN HOLE OF SOIL SORTING MACHINE}TECHNICAL FIELD [0001] The present invention relates to an apparatus for preventing retinal force in a soil sorter,

본 발명은 토사선별장치의 망막힘 방지장치에 관한 것으로, 보다 상세하게는 매립쓰레기를 1차 선별한 후 수집된 토사를 2차 정밀 분리할 때 정밀 분리용 스크린에서 발생하는 망막힘 현상을 신속하고 원활하게 해소할 수 있도록 개선된 토사선별장치의 망막힘 방지장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for preventing retinal force in a soil separation apparatus, and more particularly, The present invention relates to an apparatus for preventing retinal force in a soil sorter.

통상 쓰레기매립장(위생, 비위생)은 쓰레기의 운반효율을 감안하여 대개 대도시 인근에 위치하는데, 특히 비위생 쓰레기 매립장의 경우 무작위로 쓰레기가 매립되는 관계로 토사 및 불연물의 활용 또는 가연물의 소각을 위해 그 처리를 위한 종류별 선별작업이 불가피할 수밖에 없다.In general, waste landfills (sanitary and unsanitary) are located near metropolitan areas in consideration of the efficiency of transporting waste. Especially in the case of non-sanitary landfills, waste landfills are randomly buried, It is inevitable that sorting is done for each type.

예컨대, 굴착된 쓰레기는 토사 및 콘크리트 덩어리, 벽돌, 돌덩이와 같이 재활용이 가능하면서 태우기 어려운 불연물과 함께, 비닐천이나 나무토막과 같이 재활용이 곤란하여 소각 처리해야 하는 가연물도 함께 섞여 있는 관계로, 매립 쓰레기 전체를 종류별로 정확하게 선별작업하기 위한 선별장치의 필요성이 요구되고 있다.For example, excavated garbage can be recycled, such as sand and concrete lumps, bricks, and stones, as well as incombustible incombustible materials such as vinyl cloth and wood slabs, There is a need for a sorting apparatus for accurately sorting the entire garbage by type.

이러한 요구에 따라, 본 출원인은 매립쓰레기 선별을 위해 각고의 노력을 경주한 결과, 등록특허 제0250854호, 등록특허 제0273840호, 등록특허 제0428377호, 등록특허 제0428378호, 등록특허 제0457488호, 등록특허 제0475287호, 등록특허 제0482824호, 등록특허 제0528131호, 등록특허 제0528129호, 등록특허 제0729577호, 등록특허 제0818898호, 등록특허 제0952073호 등 다수의 특허 기술을 개발한 바 있고, 이를 실용화하여 현재 여러 현장에서 상기 기술들이 활발하게 활용되고 있다.In accordance with this demand, the present applicant has endeavored to make efforts to sort out the landfill waste, and as a result, it has been found that the inventors of the present invention have found that, , Patent No. 0475287, No. 0482824, No. 0528131, No. 0528129, No. 0729577, No. 0818898, No. 0952073, etc. And these technologies have been actively utilized in various fields at present.

특히, 매립지 쓰레기 선별과 관련하여, 본 출원인이 완성한 처리 시스템에 따르면 굴착쓰레기가 회전형 드럼스크린으로 이루어진 토사분리기를 통해 토사와 상대적으로 큰 불연물 및 가연물로 분리되고, 토사가 분리된 불연물 및 가연물은 다시 다수의 가연물분리기를 거치면서 불연물과 가연물로 완벽하게 분리되며, 분리된 가연물은 건조, 파쇄 등 후속공정을 거쳐 연료화되고, 불연물은 재활용이 가능한 것과 그렇지 않은 것으로 분류된 뒤 용처별로 반송되거나 폐기처분된다.Particularly, in relation to the sorting of landfill waste, according to the treatment system completed by the present applicant, the excavated garbage is separated into the relatively large incombustibles and the combustible substances with the gravel through the slurry separator composed of the rotary drum screen, It is separated into incombustible and combustible materials through a number of flammable separators. The separated combustible materials are converted into fuel through subsequent processes such as drying and crushing, and incombustibles are classified as those which can be recycled and those which are not, do.

이때, 토사분리기를 통해 1차 분리된 토사는 입도가 크고 불순물이 많기 때문에 복토재 등 재활용 가능한 토사 규격에 맞추기 위해 토사정밀분리장치로 반송된 후 재차 정밀분리되게 된다.In this case, since the firstly separated gravels are large in size and have a large amount of impurities, they are transported to the gravel-to-gravel separator in order to meet the recyclable gravel specifications.

그런데, 토사정밀분리장치에 사용되는 회전형 드럼스크린은 분리할 토사의 입도가 미세하기 때문에 잦은 망막힘 문제를 야기시킨다.However, the rotating type drum screen used in the dust and dirt separator causes frequent retinal force problems because the particle size of the soil to be separated is minute.

그럼에도 불구하고, 지금까지 토사정밀 분리시 스크린의 망막힘 문제를 해소하기 위해 스크린 드럼외부에 플라시틱 회전 브러쉬를 장착해 사용해오고 있으나, 드럼스크린 구조상 철판으로된 타공망으로 제작되어 있어 드럼 외부만 청소하는 역할만 할뿐 실제적으로 망막힘을 주도하는 드럼내부에는 미치지 못하여 망막힘 해소에는 도움이 되지 못하여 토사의 분리률이 낮아 2차, 3차 재선별하는 번거로움과 많은 비용이 발생하였다.
Nonetheless, to solve the problem of retina force of the screen when separating the Tosa precision so far, we have used a plastic rotary brush outside the screen drum, but since it is made of a perforated screen made of iron plate on the structure of the drum screen, But it did not help the retinal power because it did not reach the inside of the drums which led to the retinal force. Therefore, the separation rate of the soil was low and it was troublesome and costly to sort out the secondary and tertiary materials.

본 발명은 상술한 바와 같은 종래 기술에 따른 문제점을 감안하여 이를 해결하고자 창출된 것으로, 회전형 드럼스크린을 통해 1차 분리된 토사를 미세 망공을 갖는 드럼스크린을 이용하여 재차 미세하게 정밀 분리하고자 할 때 정밀분리용 드럼스크린에서 발생되는 망막힘 현상을 신속하고 정확하면서 작업 도중에 자동적으로 해소시켜 원활한 선별작업이 이루어질 수 있도록 한 토사선별장치의 망막힘 방지장치를 제공함에 그 주된 목적이 있다.

도 1 내지 도 3에 도시된 바와 같이, 본 발명에 따른 토사선별장치의 망막힘 방지장치는 드럼스크린(100)을 포함한다.As shown in FIGS. 1 to 3, the retina force prevention apparatus of the soil sorter according to the present invention includes a drum screen 100.

상기 드럼스크린(100)은 일정 길이를 갖는 원통형상의 드럼 외주면에 정밀 선별을 위한 미세 망공(110)이 형성된 구조를 가지며, 상기 미세 망공(110)은 크기를 달리할 수 있다.The drum screen 100 has a structure in which a minute vortex 110 for accurate selection is formed on a cylindrical drum outer peripheral face having a predetermined length, and the minute vortex 110 may have a different size.

그리고, 상기 드럼스크린(100)은 일측단 외주면 자체에 구동기어(미도시)가 형성되고, 상기 구동기어는 구동모터(미도시)와 같은 구동원에 마련된 기어와 치결합되어 직접 구동되는 방식으로 구동됨이 바람직하다.A drive gear (not shown) is formed on the outer circumferential surface of the drum screen 100, and the drive gear is meshed with a gear provided in a drive source such as a drive motor .

한편, 상기 드럼스크린(100)의 외주면에는 상기 구동기어(미도시)와 간섭되지 않는 범위내에서 다수 바람직하기로는 도시와 같이, 4개의 유도롤러레일(120)이 형성된다.On the other hand, four guide roller rails 120 are formed on the outer circumferential surface of the drum screen 100 within a range that does not interfere with the driving gear (not shown).

아울러,상기 유도롤러레일(120)에는 반경방향으로 일정 간격을 두고 다수개의 타격유도돌기(130)가 일체로 돌출 형성된다.In addition, a plurality of impact guiding protrusions 130 are integrally protruded from the guide roller rail 120 at predetermined intervals in the radial direction.

이때, 상기 타격유도돌기(130)는 한 개의 드럼스크린(100) 당 8개씩 2개의 드럼스크린에 총 16개가 구비됨이 바람직하나, 도면에서는 도시의 편의상 적은 갯수로 표시하였을 뿐이다.At this time, it is preferable that the number of the impact inducing protrusions 130 is sixteen on the two drum screens, one for each one drum screen 100, but the number is limited to a few for convenience of illustration.

또한, 상기 드럼스크린(100)의 상부에는 하우징 형태의 고정프레임(F)이 구비되고, 상기 고정프레임(F)에는 회전유동될 수 있게 베어링 고정된 다수, 바람직하기로는 4개의 지지대(S)가 구비되며, 상기 지지대(S)의 단부에는 중량물인 롤러고정대(140)가 연결된다.A fixed frame F in the form of a housing is provided on the upper portion of the drum screen 100 and a plurality of preferably four supporting bars S fixed to the fixing frame F so as to be rotatably moved And a roller fixing table 140, which is a heavy material, is connected to the end of the support S.

그리고, 상기 롤러고정대(140)의 하단면에는 일정크기의 스크래퍼(150)가 다수개 부착되어 드럼스크린(100)의 외주면과 접한 상태로 드럼스크린(100)의 회동력에 의해 회전될 수 있도록 무동력으로 설치되어 에너지 낭비를 효과적으로 줄여 주며, 망막힘 방지 효율을 더욱 높이게 된다.A plurality of scrapers 150 of a predetermined size are attached to the lower end surface of the roller fixing table 140 so as to be rotated by the turning force of the drum screen 100 in contact with the outer circumferential surface of the drum screen 100, , Which effectively reduces energy waste and further enhances retinal force prevention efficiency.

이 경우, 상기 스크래퍼(150)는 고무판과 같은 소재로 형성됨이 바람직하다.In this case, the scraper 150 is preferably made of the same material as the rubber plate.

아울러, 상기 롤러고정대(140)의 양단에는 타격롤러(160)가 회전가능하게 설치된다.In addition, a striking roller 160 is rotatably installed at both ends of the roller fixing table 140.

상기 타격롤러(160)는 상기 유도롤러레일(120)과 접한 상태로 무동력으로 회전구동되며, 상기 유도롤러레일(120) 상에 일정간격으로 돌출되어 있는 타격유도돌기(130)를 만날 때 마다 이를 타고 넘으면서 그때 생긴 단차만큼 툭 떨어지면서 드럼스크린(100)에 충격을 가해 망공(110)의 막힘 현상을 해소시키게 된다.The striking roller 160 rotates in a non-reciprocating manner in contact with the guide roller rail 120. When the striking guide protrusion 130 protrudes at a predetermined interval on the guide roller rail 120, So that the drum screen 100 is impacted and the clogging of the vents 110 is eliminated.

이때, 스크래퍼(150)도 함께 타격하므로 스크래퍼(150)를 비롯한 타격롤러(160)는 타격시 드럼스크린(100)을 찌그러뜨리지 않아야 된다.At this time, since the scraper 150 is also struck together, the scraper 150 and the striking roller 160 should not crush the drum screen 100 when struck.

때문에, 타격을 가하되 충격량을 줄일 수 있도록 상기 타격롤러(160)의 외주면은 고무로 코팅되며, 상기 스크래퍼(150)도 고무판으로 형성되어야 한다.Therefore, the outer circumferential surface of the striking roller 160 is coated with a rubber so that the impact can be reduced, and the scraper 150 is also formed of a rubber plate.

여기에서, 상기 타격유도돌기(130)는 직각삼각형상이 바람직하며, 직각삼각형의 빗면이 회전방향 쪽으로 배치되고, 회전방향 반대쪽으로는 직각면이 배치되도록 함으로써 유도롤러레일(120) 위를 따라 이동하는 타격롤러(160)와, 스크린 망공(110) 위를 쓸고 지나가는 스크래퍼(150)가 타격유도돌기(130)의 빗면 낙차를 이용하여 스크래퍼(150)가 스크린 망공(110)을 타격함으로서 스크린 망공(110)에 토사의 막힘을 효율적으로 털어줌으로서 망막힘을 방지한다.Here, the impact guiding protrusion 130 is preferably a right triangular shape, and moves along the guiding roller rail 120 by arranging the oblique angle of the right triangle in the rotational direction and the right angle in the opposite direction of the rotational direction The scraper 150 strikes the screen screen 110 using the striking roller 160 and the scraper 150 sweeping over the screen screen 110 by using the slanting surface of the striking protrusion 130 to strike the screen screen 110 ) Effectively prevents clogging of the soil to prevent retinal force.

이 경우, 상기 타격롤러(160)의 유동을 더욱 원활하게 하기 위해 상기 빗면이 곡률을 가지면 더욱 좋다.In this case, it is more preferable that the oblique face has a curvature in order to smooth the flow of the striking roller 160.

이 경우, 상기 곡률은 하부로 오목한 형상이 바람직하며, 이를 통해 타격롤러(160)가 쉽게 타고 오를 수 있게 된다.In this case, the curvature is preferably concave downward, so that the striking roller 160 can easily ride.

한편, 상기 지지대(S)의 상면에는 탄성스프링(170)의 하단이 고정되고, 상기 탄성스프링(170)의 상단은 상기 고정프레임(F)에 고정되어 상기 지지대(S)를 탄성 유동가능하게 하여 준다.The lower end of the elastic spring 170 is fixed to the upper surface of the support S and the upper end of the elastic spring 170 is fixed to the fixed frame F to allow the support S to elastically flow give.

이때, 상기 탄성스프링(170)은 단순히 탄성유동만을 위해 구비되는 것이 아니라, 상기 스크래퍼(150)를 포함한 롤러고정대(140) 등의 중량을 탄성적으로 잡아 주기 때문에 중량을 줄여 드럼스크린(100)에 가해지는 직접적인 충격을 완화시켜 스크린 망공(110)의 막힌 토사만 털어주어 망막힘 방지효율을 더욱 높이게 된다.At this time, the elastic spring 170 is not merely provided only for elastic flow, but it reduces the weight of the roller fixing table 140 including the scraper 150, The direct impact applied thereto is relieved, and only the clogged soil of the screen vents 110 is shaved to further enhance the retinal force prevention efficiency.

즉, 상기 타격롤러(160), 스크래퍼(150)는 드럼스크린(100)의 외주면과 직접 접촉된 상태로 유지되고 있다가 타격롤러(160)가 상기 타격유도돌기(120)를 만나면 롤러가 이를 타고 타격유도돌기(120)의 최대 돌출높이, 이를 테면 상사점까지 상승하게 된다.That is, the striking roller 160 and the scraper 150 are kept in direct contact with the outer circumferential surface of the drum screen 100. When the striking roller 160 meets the striking-inducing protrusions 120, The maximum projecting height of the striking guiding projection 120, for example, the top dead center, is raised.

그런 후, 상사점을 지나면 접촉지지되는 부분이 없어지게 되므로 순간적으로 낙하하면서 드럼스크린(100)의 외주면을 타격하게 되는 것이다.Then, after passing through the top dead center, the portion to be contact-supported disappears, so that the drum surface 100 is instantly dropped and hit the outer circumferential surface of the drum screen 100.

그러므로, 충격량을 크게 하려면 상기 타격유도돌기(200)의 돌출 높이를 높이는 것도 하나의 방편이고, 상기 타격롤러(300) 상부의 탄성스프링(126) 장력을 줄여 중량을 늘리는 것도 하나의 방편이며, 이 둘을 동시에 조절할 수도 있다.Therefore, it is also a way to heighten the protrusion height of the impact guiding protrusion 200 in order to increase the amount of impact, and it is also a way to increase the weight by reducing the tension of the elastic spring 126 on the pressure roller 300, You can control both at the same time.

뿐만 아니라, 탄성스프링(170)의 탄성계수를 조절하는 것도 충격량을 변화시키는 하나의 요인이 될 수 있다.
In addition, adjusting the modulus of elasticity of the elastic spring 170 may be one factor for changing the amount of impact.
