The present invention provides a device for reducing sludge and water using a harmlessly dissipated filter, which can remarkably lower the volume and water with a material which is harmless and eco-friendly, and is from dissipated nature, and a material which can indefinitely endure a high-pressure load.

Description

무해 소멸되는 필터를 이용한 슬러지감량 및 수분저감 장치 {A Device to Reduce Sludge and Reduce Water Using a harmless Filter}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sludge reduction and moisture reduction device using a filter which is harmlessly extinguished,

본 발명은 무해 소멸되는 필터를 이용한 슬러지감량 및 수분저감 장치에 관한 것으로, 더욱 상세하게는 물의 정화과정에서 양산되는 슬러지를 매립 전 압축하여 부피를 최소화 하고 수분을 최대로 줄이며, 매립 가능한 무해 소멸 되는 필터를 이용한 슬러지감량 및 수분저감 장치에 관한 것이다.More particularly, the present invention relates to a sludge reducing and water reducing apparatus using a filter which is harmlessly extinguished. More particularly, the present invention relates to a sludge reduction and water reducing apparatus using a filter that minimizes volume, minimizes water content, To a sludge weight reduction and a water reduction apparatus using a filter.

일반적으로 상하수도 정화 및 오폐수의 정화과정에서 발생한 슬러지는 폐수와 함께 응집제 첨가 후 펌프로 필터 또는 벨트에 투입해 압축하고, 롤러로 눌러서 물과 슬러지를 분리하여 수분과 관계없이 2차 처리를 해 왔으나 여전히 많은 문제점이 있음에도 지금까지 매립에 의존할 수밖에 없다.Generally, the sludge generated in the purification process of wastewater and wastewater is added to the filter or belt by the pump after adding the coagulant together with the wastewater, and the water and the sludge are separated by pressing with the roller, Although there are many problems, we have to rely on landfill so far.

그러나, 상기와 같이 처리하는 방법은 최종 배출슬러지의 함수율이 높아 매립 가능 적정 함수율에는 너무 많은 차이가 있으므로 하여 매립장 침출수 유출의 한 원인이 되고, 배출과정에서 컨베이어 케이크 홉퍼 등을 거치면서 부풀어 부피가 크며 다량의 수분을 함유하고 있다. 그로인해, 심하게는 이송과정에서 도로에 오폐수를 무단 방출하는 꼴이 되는 문제점이 있었다.However, the method of the above-mentioned treatment is a cause of leakage of leachate in the landfill due to a high water content of the final discharge sludge and too much difference in the proper filling water content, and the puffing volume becomes large as it passes through a conveyor cake hopper etc. Contains a large amount of water. Therefore, there is a problem that the wastewater is discharged to the road unintentionally during the transportation process.

그리하여, 상기의 작업방법은 함수율 초과와 2배 이상의 부피로 운송비 및 매립 장소를 많이 차지함은 물론 함수율 기준치를 맞추기 위해서는 또 한 번의 공정이 필요함이 바람직하다.Thus, it is desirable that the above-mentioned working method requires a further process in order to meet the moisture content standard value as well as the transportation cost and the landfill site with a water content exceeding the water content and a volume of 2 times or more.

한편, 상기와 같은 작업방법은 수년간 이어져왔으나 법의 개정으로 기준치 통과와 매립처리 후 침출수의 누수로 토양의 오염과 악취로 지역민들의 고통이 문제점으로 남아 있었다.On the other hand, the above-mentioned working method has been continued for many years, but due to the revision of the law, leakage of leachate after passage of the reference value and landfill has caused problems of the local people due to soil pollution and odor.

상기와 같은 문제점을 해결하기 위하여, 본 발명은 무해 친환경필터를 이용한 프레스 가압탈수장치를 제공하는 것을 해결과제로 한다.In order to solve the above-mentioned problems, the present invention provides a pressurizing and dewatering apparatus using a harmless environmentally friendly filter.

상기의 과제를 해결하기 위하여, 본 발명은 기존의 필터와 다른 무해 소멸되는 1회용 필터, 필터를 보호하고 받쳐주는 다공판, 상하가 개방된 통형상의 슬러지케이지(하부금형), 케이지에 내부를 상하 작동하는 펀치(상부금형), 케이지에 공급된 슬러지를 가압 탈수시키는 프레스, 케이지에 슬러지를 압송하는 펌프, 고형의 슬러지를 케이지로부터 분리하기 위한 실린더를 제공한다.In order to solve the above-mentioned problems, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a sludge cage (lower mold) A punch (upper mold) which operates up and down, a press for dewatering the sludge supplied to the cage, a pump for feeding the sludge to the cage, and a cylinder for separating the solid sludge from the cage.

상기 과제에서 특기할 사항은 기존의 방식은 필터와 벨트의 막힘을 고압으로 세척하지만 더 이상의 압력을 가하면 여과망의 막힘이 세척불가하며 함수율을 더이상 낮추기에는 한계가 있다.What is special about the above problem is that the conventional method is to clean the clogging of the filter and the belt with high pressure, but when the pressure is further applied, the clogging of the filter net can not be cleaned and the water content can not be lowered any further.

그리하여, 본 발명에서는 기존 방식이 백과 벨트를 사용하는데 비해 백 대신 케이지(하부금형), 펀치(상부금형)로 구성하고, 케이지의 내부면적과 동일한 다공판을 오수통로가 가공된 프레스의 베이스에 영구고정하고, 케이지 내부에 미세여과 층이 압력에 대응 수 있는 무해하면서 1회용으로 슬러지와 함께 매립 가능한 소멸되는 필터가 제공됨이 바람직하다.Therefore, in the present invention, the conventional method is composed of a cage (lower mold) and a punch (upper mold) instead of a bag, and a perforated plate having the same internal area as the cage is inserted into the base of the press- It is preferable to provide a decaying filter capable of being buried in the cage together with the sludge in a single use while the fine filtration layer can cope with the pressure harmlessly.

여기서, 고 하중에 견디며 미세여과를 할 수 있는 소재가 중요하다고 할 것이다. 두 가지를 충족시킬 수 있는 소재로는 톱밥(예)을 비롯한 목분 류, 모래를 비롯한 흙 종류, 쌀겨를 비롯한 곡물가루 등 1회용으로 단시일에 자연으로 돌아갈 수 있는 만족스런 필터소재임이 확실하다.Here, a material capable of enduring high load and capable of microfiltration is important. It is certain that the material that can satisfy both of them is a satisfactory filter material which can return to nature in a short time by disposing such as sawdust (eg), woods such as sand, soil type, rice bran and grain powder.

또한, 상기 무해 소멸되는 필터를 이용한 슬러지 감량 및 수분저감 장치의 1행정은 케이지와 펀치를 제 위치에 고정시키고 프레스를 상승시킨 후 다공판위에 톱밥(예)을 일정 뚜께로 고루적층 시킨 후, 슬러지를 케이지에 적정량을 투입하고, 다시 위에 약간의 톱밥(예)을 고루적층 시킨다. 프레스를 일정 위치까지 하강시켜 펀치로 케이지내의 슬러지를 가압 탈수시킨 후 프레스는 상승하고 케이지가 상승하면서 고형의 슬러지와 분리 된다. 이후 고형의 슬러지는 직각 방향의 뒤쪽의 실린더가 밀어내어 앞쪽으로 반출시키면 1행정이 끝난다.Further, in the one stroke of the sludge reducing and water reducing apparatus using the harmlessly-disappearing filter, the cage and the punch are fixed in position, the press is elevated, the sawdust (eg) is stacked on the perforated plate uniformly, Is put into the cage in an appropriate amount, and a little sawdust (for example) is stacked on top of it again. After the press is lowered to a certain position, the sludge in the cage is pressurized and dehydrated by punching, the press is elevated, and the cage rises and separates from the solid sludge. Then, the solid sludge is discharged by pushing out the cylinder at the rear side in the perpendicular direction, and one stroke is finished.

한편, 톱밥은 여기서 충분한 필터 역할을 함은 물론 상부의 압력이 강해질수록 더욱 압축되며 양질의 필터로 완성됨이 바람직하다.On the other hand, the sawdust serves as a sufficient filter here, and it is preferable that the sawdust be further compressed and finished with a high-quality filter as the pressure of the upper part becomes stronger.

그리고, 상기 무해 소멸되는 필터를 이용한 슬러지감량 및 수분저감 장치작업에서 고 하중으로 압축하므로 탈수는 물론 부피가 반으로 축소되면서 고형의 슬러지가 케이지에서 분리가 어려울 수 있기에 유압 실린더의 힘으로 케이지와 슬러지를 분리시킴이 바람직하다.In addition, since the sludge is reduced to a high load in the operation of reducing the amount of sludge using the harmlessly-decomposable filter and the water-reducing device, the volume of the sludge is reduced by half as well as the volume of the sludge is difficult to separate from the cage. .

상기의 해결 수단을 통해서, 본 발명의 무해 소멸되는 필터를 이용한 슬러지 감량 및 수분저감 장치는 다음과 같은 효과를 제공한다.Through the above-mentioned solution, the sludge reduction and moisture reduction apparatus using the harmlessly-disappearing filter of the present invention provides the following effects.

첫째, 기존의 연속 사용되는 필터 및 벨트에 비해, 무해 소멸되는 필터는 1회사용으로 슬러지와 같이 버림으로 필터의 막힘에 문제가 없음으로 프레스의 능력껏 가압하게 되고 다른 방식에 비해 감량은 물론, 더욱 낮은 함수율을 얻을 수 있고 다른 작업방식에서 나온 슬러지의 감량과 함수율 저감에도 용이하게 사용할 수 있다.First, compared with conventional continuous filters and belts, the filter which is destroyed by harmlessness is used as one time, as it is like sludge, there is no problem in the clogging of the filter, so the pressure is pressed up to the capacity of the press, It is possible to obtain a lower water content and to easily reduce sludge loss and water content from other working methods.

둘째, 1회용 필터로 슬러지와 같이 매립하더라도 친환경적이며 많은 감량으로 운송비(약50%) 절감과 함수율저하로 도로의 낙수에 인한 피해를 없앨 수 있다.Second, it is eco-friendly even if it is buried with sludge as a disposable filter. It can reduce the transportation cost (about 50%) and reduce the water content due to the drop of water due to a lot of weight loss.

셋째, 상기 무해 소멸되는 필터를 이용한 슬러지감량 및 수분저감 장치는 1행정에 많은 양의 슬러지를 처리하고, 2대의 프레스로 교차로 연속처리가 가능하며 며, 많은 양의 슬러지도 처리할 수 있다.Third, the sludge reduction and moisture reduction apparatus using the harmlessly extincting filter can process a large amount of sludge in one stroke, enable continuous processing at an intersection with two presses, and can treat a large amount of sludge.

넷째, 따라서, 무해 소멸되는 필터를 이용한 슬러지감량 및 수분저감 장치는 함수율 저하로 건조를 비롯한 후 공정에서도 연료비, 전기 등을 현저히 줄일 수 있다.Fourth, therefore, the sludge weight loss and water reduction device using the filter which is harmlessly decayed can significantly reduce the fuel cost and the electricity in the post-process including the drying due to the decrease of the water content.

다섯째, 다른 방식에 비해 장비의 수가 적으며 장소를 덜 차지하고 유지 보수가 용이하다.Fifth, the number of equipment is smaller than other methods, it occupies less space and maintenance is easy.
