본 고안은 각종 생활폐기물 또는 산업폐기물에 함유된 수분을 탈수하여 고형물과 액체가 완전분리, 탈수되도록하는 원심탈수기에 관한 것으로 특히 농장이나 목장등으로부터 배출되는 축산폐기물을 간편, 신속하게 처리하여 탈수효율을 증대할 수 있도록 한 것이다.The present invention relates to a centrifugal dehydrator which completely dehydrates and dehydrates solids and liquids by dehydrating water contained in various household wastes or industrial wastes. Especially, the dehydration efficiency is easily and quickly treated by livestock waste discharged from farms or ranches. It is to increase the.

본 고안의 원심탈수기는 폐기물 원료의 공급과 외주연에 설치되어 각각 회전 작동하는 내, 외측여과드럼에 다수개의 미세한 탈수구멍을 형성하되, 내, 외측여과드럼의 탈수구멍을 동일하게 형성하거나 외측의 탈수구멍이 내측의 탈수구멍 보다 조금 작게끔 형성하므로서 공급판을 통해 여과드럼으로 투입되어 원심력에 의해 폐기물 원료의 고형물과 액체가 회동하면서 상기 여과드럼에 충격하며 여과 탈수할 때 내측 여과드럼에 의해 1차로 여과 탈수된 후, 외측여과드럼에 의해 2차로 여과탈수처리되므로서 종래보다 탈수효율을 높일 수 있을 뿐만 아니라, 상기 폐기물 원료의 공급관 외주연에는 다수개의 프로펠러형 충격판을 돌출되게끔 설치하여서 폐기물 원료의 고형물과 액체를 상기 충격판에 의해 원심력에 더불어 반전작용을 시켜 주어 탈수효과를 증대할 수 있는 것이다.The centrifugal dehydrator of the present invention forms a plurality of fine dehydration holes in the inner and outer filtration drums installed at the supply and the outer periphery of the waste material, respectively, and rotates, respectively. As the dehydration hole is formed to be a little smaller than the inner dehydration hole, it is introduced into the filter drum through the supply plate, and the solid material and the liquid of the waste raw material are rotated by the centrifugal force to impact the filter drum. After filtration and dehydration by car, the filtration and dehydration process by the second filtration drum to improve the dewatering efficiency than the conventional one, and by installing a plurality of propeller-type shock plate protrudes on the outer periphery of the feed pipe of the waste raw material waste The solids and liquid of the raw material are inverted by centrifugal force by the impact plate. It is that the effect can be increased.

일반적으로 각종 폐기물, 특히 농축산 폐기물은 오수에 현탁된 부패한 유기물질인 고형물과 액체가 혼합된 것으로, 이를 통상의 방법으로 처리하는 경우에 오수 참전지와 같은 처리 시설물에서 수거된 슬러지는 통상 90중량% 이상의 수분을 함유하고 있으며, 이러한 슬러지는 통상 버리거나 태우기 때문에 가급적 충분히 탈수되어야 한다.In general, various wastes, especially agricultural and livestock wastes, are a mixture of solids and liquids, which are suspended organic substances suspended in sewage, and sludge collected in a treatment facility such as sewage sewage cells is usually 90% by weight when the wastewater is treated in a conventional manner. It contains the above water and should be sufficiently dehydrated as much as possible because such sludge is usually discarded or burned.

특히 연료를 더 필요로 하지 않고 소각시키거나, 자발 소각시키기 위해서는 슬러지의 함수량이 60중량% 이하, 바람직하게는 50중량% 이하가 되어야 하는데, 일반적으로 슬러지는 회분, 염화철 등의 무기 조정제 또는 중합 응집제 등의 유기 조정제의 첨가에 의해 응집된다.In particular, in order to incinerate without further fuel, or to spontaneously incinerate, the water content of the sludge should be 60% by weight or less, preferably 50% by weight or less. Generally, the sludge is an inorganic modifier such as ash, iron chloride, or a polymerization flocculant. It aggregates by addition of organic regulators, such as these.

응집된 슬러지는 진공 탈수기, 원심 탈수기, 벨트 프레스, 필터 프레스 등에 의해 탈수되어 과화된다.The agglomerated sludge is dehydrated by a vacuum dehydrator, a centrifugal dehydrator, a belt press, a filter press or the like and is supercharged.

이와같이 탈수되고 고화된 슬러지를 1차 탈수된 슬러지라 한다.This dewatered and solidified sludge is called primary dewatered sludge.

통상 1차 탈수된 슬러지는 함수량이 70중량% 이상으로서, 예를 들면 특히 벨트 프레스 또는 필터 프레스로 탈수되었을 때, 70 내지 85중량%이다.Usually the primary dewatered sludge has a water content of 70% by weight or more, for example, 70 to 85% by weight, especially when dewatered by a belt press or a filter press.

1차 탈수된 슬러지는 함수량이 70중량%, 이하로는 거의 탈수되지 않는 것으로 알려져 있으며, 고압하에서 압축하는 것은 여과포를 들어 붙게 하기 쉬워 더 이상 함수량을 감소시킬수 없었던 것이다.It is known that the primary dewatered sludge has almost 70% by weight of water, which is hardly dehydrated. Compression under high pressure is easy to hold the filter cloth, and thus it is no longer possible to reduce the water content.

본 고안은 상기와 같은 종래의 낮은 탈수효을 해결하고져 안출된 것으로 각각, 회전작동하는 내, 외측여과드럼으로 구분 형성된 이중구조의 여과드럼과 그 중심부에서 회전작동하는 폐기물 원료의 공급관 외주연에 설치된 반전용 충격판에 의하여 폐기물의 탈수효율을 최대화 시켜 주는 원심탈수 장치를 제공하고져 함에 고안의 목적이 있는 것이다.The present invention solves the conventional low dehydration effect as described above, each of which is formed on the inner periphery of the inner, outer filtration drum of the dual structure formed in the rotating drum and the half installed on the outer periphery of the supply pipe of the waste raw material rotating in the center The purpose of the present invention is to provide a centrifugal dewatering device that maximizes the dewatering efficiency of waste by a dedicated impact plate.

이와 같은 본 고안의 원심탈수장치에 의한 탈수처리과정을 첨부도면 제 5도의 작동설명도를 참조하여 설명하면 다음과 같다.The dehydration process by the centrifugal dehydration apparatus of the present invention as described above with reference to the operation diagram of Figure 5 attached as follows.

탈수장치(10)의 중심부에 삽입설치되어 구동장치(50)에 의해 감속 회전하는 공급관(20)을 통하여 폐기물 슬러지를 공급하면, 상기 공급관(20)에 형성된 다수개의 공급구멍(21)을 통하여 구동장치(50)에 의해 동일방향 또는 역방향으로 각각 회전작동하는 내, 외측여과드럼(30)(40)의 내부로 폐기물 슬러지가 공급되면서 공급관(20)의 회전작동으로 원심력에 의해 내측여과드럼(30) 내주면에 충격되는데, 이때 내측여과드럼(30)에 형성된 탈수구멍(31)에 의해 슬러지에 함유된 수분이 탈수되면서 탈수된 수분과 이에 포함된 고형분은 외측여과드럼(40)애 재차 충격되어 다시 고형분에 함유된 수분이 탈수처리되는 것이다.When the waste sludge is supplied through the supply pipe 20 inserted into the center of the dewatering device 10 and decelerated and rotated by the driving device 50, it is driven through the plurality of supply holes 21 formed in the supply pipe 20. As the waste sludge is supplied into the inner and outer filtration drums 30 and 40 which are respectively rotated in the same direction or in the opposite direction by the device 50, the inner filtration drum 30 is driven by the centrifugal force by the rotational operation of the supply pipe 20. ) The inner circumferential surface, which is dehydrated by the dehydration hole 31 formed in the inner filtration drum 30, the dehydrated water and the solids contained therein are impacted again by the outer filtration drum 40 again The water contained in the solid is dehydrated.
