Description

슬럿지 탈수 처리장치Sludge Dewatering Treatment System

본 발명은 슬럿지의 종류에 구애받지 않고, 각종 슬럿지에 포함된 수분을 단시간에 효율적으로 탈수함은 물론 여과포에 압착된 슬럿지케이크를 자동으로 탈거 할 수 있으며 여과포의 자동세척이 가능하도록 하여 운전이 간편하고 보수유지비등을 절감할 수 있는 슬럿지 탈수 처리장치에 관한 것으로써, 상기 슬럿지를 슬럿지 탱크로부터 펌프에 의해 슬럿지 분산장치로 투입하여 슬럿지가 상부챔버에 고르게 분포되도록 유도하고, 상부챔버에 유입된 슬럿지는 1단계로 자중에 의해 여과되어하방의 하부챔버를 통해 탈수되도록 하고, 2단계로 고압의 공기를 주입시켜 가압하므로써 슬럿지 내에 잔존하고 있는 잔여수분까지 여과 및 탈수 시킨후, 1단계와 2단계 가압에 의해 탈수된 슬럿지는 여과포에 압착되어 케이크화 되고 탈수과정이 끝나면 상부에 장착된 실린더에 의해 상부챔버가 상승하게 되고, 구동모터에 의해 여과포는 이송되게 된다. 이때 여과포에 압착된 슬럿지케이크는 연속분사되는 공기분사노즐에 의해 여과포에서 이탈되면서 스크래퍼에 의해 여과포로부터 완전히 이탈된다. 한편 타측의 물분사노즐에서 분사되는 물에 의해 여과포가 세척되어 다음 공정을 위해 상부챔버와 하부챔버 사이로 유입된다. 다음 공정 준비가 완료되면 상부 실린더에 의해 상부챔버가 다시 하강하여 하부챔버와 결합되고, 다시 슬럿지가 상부챔버내로 유입되면서 순환공정이 자동적으로 행하여지도록 하는 슬럿지 탈수 처리장치에 관한 것이다.The present invention is not limited to the type of sludge, the water contained in the various sludge can be dehydrated in a short time efficiently and automatically remove the sludge cake squeezed on the filter cloth and easy to operate by allowing automatic cleaning of the filter cloth And a sludge dewatering treatment device capable of reducing maintenance costs. The sludge is introduced into the sludge dispersing device by a pump from a sludge tank to induce the sludge to be evenly distributed in the upper chamber, and the sludge introduced into the upper chamber. Is filtered by its own weight in one step to be dehydrated through the lower chamber below, and by injecting high pressure air in two steps to filter and dewater to the residual moisture remaining in the sludge, and then press the first and second steps The sludge dehydrated by squeezed into the filter cloth was caked and dehydrated at the top. The upper chamber is raised by the mounted cylinder, and the filter cloth is conveyed by the driving motor. At this time, the sludge cake pressed on the filter cloth is completely separated from the filter cloth by the scraper while being separated from the filter cloth by the air spray nozzle continuously sprayed. Meanwhile, the filter cloth is washed by the water sprayed from the water spray nozzle on the other side, and is introduced between the upper chamber and the lower chamber for the next process. When the preparation of the next process is completed, the upper chamber is lowered again by the upper cylinder and coupled to the lower chamber, and the sludge dewatering treatment apparatus for allowing the circulation process to be automatically performed as the sludge flows into the upper chamber again.

일반적으로 많이 사용되고 있는 탈수 처리장치는 필터 프레스(FILRE PRESS) 장치와 벨트 프레스(BELT PRESS) 장치가 주로 사용되고 있는 실정인바, 상기 필터 프레스 장치는 농축조로부터 슬럿지를 고압펌프에 의해 여과판으로 유입되고,유입된 슬럿지는 펌프의 충진압 및 실린더의 가압력에만 의존하여 탈수가 이루어지므로 탈수시간이 길어지고 탈수율도 저하된다. 또한 탈수된 슬럿지케이크의 탈착방법도 수동 또는 진동에 의한 방법으로 여과판으로부터 이탈되지 않은 슬럿지케이크를 처리하기 위하여 항상 작업자가 상주하여야 하는 불편함이 있으며, 여과포의 세척이 곤란하여 여과포의 눈막힘 등으로 인한 탈수효율이 저하되고, 여과포의 수명도 단축된다. 최근에 이러한 단점을 보완하기 위하여 수동 세척방법이 사용되고 있으나 역방향세척(역세)이 곤란하여 형식에 지나지 않으며, 정방향 세척으로 인한 일부 슬럿지는 여과포에 더욱더 깊숙히 박혀 큰 효과를 기대하기가 어렵다.In general, a dewatering treatment device commonly used is a filter press device and a belt press device. The filter press device is introduced from a concentration tank into a filter plate by a high pressure pump. The dewatered sludge is dehydrated only depending on the filling pressure of the pump and the pressing force of the cylinder, so the dewatering time is long and the dehydration rate is lowered. In addition, the desorption method of the dewatered sludge cake is also inconvenient that a worker must always reside in order to process the sludge cake which is not detached from the filter plate by manual or vibration method. Due to the dehydration efficiency is reduced, the life of the filter cloth is also shortened. Recently, a manual washing method has been used to compensate for these drawbacks, but it is difficult to reverse washing (backwashing), which is only a form, and some sludges due to the forward washing are embedded in the filter cloth deeper and hard to expect a great effect.

또한 종래 탈수장치 중 하나인 벨트 프레스(BELT PRESS)장치는 두개의 로울러 사이에 여과포 벨트가 지나가도록 되어 있어, 이 여과포 벨트가 로울러를 지나면서 로울러에 의해 압축되도록 되어 있다. 농축조에 저장된 수분을 포함한 슬럿지가 슬럿지 탱크로 유입되면 여과벨트가 슬럿지탱크를 통과하면서 여과포 벨트 유입측으로 슬럿지가 유입된다. 이렇게 유입된 슬럿지는 여과포 벨트사이에 모여지면서 로울러 사이를 통과하게 되는데, 이때 로울러를 통과하면서 로울러가 여과포 벨트를 압축하여 슬럿지에 포함된 수분을 탈수 시킨다.In addition, the belt press (BELT PRESS) device, which is one of the conventional dehydrator, is to pass the filter cloth belt between the two rollers, so that the filter cloth belt is compressed by the roller while passing through the roller. When the sludge containing water stored in the thickener flows into the sludge tank, the sludge flows into the filter cloth belt inlet while the filter belt passes through the sludge tank. The sludge introduced in this way is passed between the rollers as they are collected between the filter cloth belts. At this time, the rollers compress the filter cloth belts to dehydrate the water contained in the sludge while passing through the rollers.

나머지 슬럿지는 로울러와의 압축에 의해 케이크(CAKE)화 되어 여과포 벨트 표면에 압착된다. 이렇게 여과포 벨트에 압착되어 케이크화된 슬럿지는 여과포벨트에 의해 이송되어 배출되는데 로울러 압착과정에서 상,하 여과포벨트에 슬럿지가 끼게되고 눈막힘이 발생하여 점차적으로 탈수효율이 저하된다. 또한 로울러에 의한 압착으로 여과포벨트의 손상이 심하여 벨트를 자주 교체하여야 하는 번거러움이 있다.The remaining sludge is caked by compression with a roller and pressed onto the surface of the filter cloth belt. The sludge that has been compressed and caked by the filter cloth belt is conveyed and discharged by the filter cloth belt. In the roller pressing process, the sludge is caught in the upper and lower filter cloth belts, and clogging occurs, and the dehydration efficiency gradually decreases. In addition, there is a hassle that the belt is frequently replaced due to severe damage to the filter cloth belt by pressing by the roller.

이와같이 종래 슬럿지 탈수처리장치는 일정시간 슬럿지를 탈수하면 필터나 여과포에 눈막힘 현상으로 인하여 탈수효율이 저하되고, 케이크화되어 압착된 슬럿지를 작업자가 일일이 탈거한후 세척하여야 하는 번거로움이 있었으며, 이물질이나 날카로운 불순물등이 포함된 슬럿지 처리시 필터나 여과포등에 손상을 입혀 처리가 불가능하며, 압착 또는 펌핑압에 의해 여과포 벨트나 여과판등에서 수분을 탈수하도록 되어 있으므로 여과포나 필터등이 쉽게 손상되어 자주 갈아주어야 하는 비경제적인 문제점이 있었다.As such, the conventional sludge dewatering treatment device dehydrates the sludge for a certain period of time, resulting in dehydration efficiency deterioration due to a clogging phenomenon in the filter or filter cloth. When the sludge treatment contains sharp impurities or other impurities, the filter or filter cloth is damaged and cannot be treated.The filter cloth or filter is easily damaged because it is dehydrated from the filter cloth belt or filter plate by pressing or pumping pressure. There was an uneconomical problem.

또한 종래의 필터 프레스 장치나 벨트 프레스 장치는 고농도의 슬럿지만 처리가 가능하여 물이 다량 함유된 저농도의 슬럿지를 탈수처리하기 위해서는 별도로 농축조를 설치하여 농축조에서 슬럿지를 농축시켜 고농도화 한후 탈수 처리를 하여야 하므로 농축조의 설치에 따른 경제적인 손실은 물론 설치면적이 넓어 좁은 장소에 설치가 부적합한 문제점을 지니고 있다.In addition, the conventional filter press device or belt press device is capable of treating only high concentration slits, so in order to dehydrate sludge containing low concentrations of water containing a large amount of water, a thickening tank must be installed separately to concentrate the sludge in a concentration tank and then dewatered. Therefore, the economic loss due to the installation of the thickening tank, as well as having a large installation area has a problem that is not suitable for installation in a narrow place.

한편 필터 프레스의 경우 슬럿지를 여과판에 고압으로 유입하여야 하므로 고압용 펌프만 사용할 수 있어 펌프의 호환성이 없으며, 적정한 고압력을 지속시키기 위해 무리한 펌핑을 하게 되어 펌프의 사용수명이 단축되는 문제점이 지적되고 있었다. 또한 필터에 유입되는 압력을 슬럿지의 종류에 맞게 조정이 불가능 하므로 탈수 가능한 압력까지 상승, 유지시키기 위하여 불필요한 시간이 낭비되는 결과를 초래하게 되어 비생산적인 문제점이 있었으며, 벨트 프레스의 경우도 여과포인 벨트를 가압하는 가압력을 슬럿지에 따라 조정이 불가능하여 높은 탈수효율을 기대하기 어렵다.On the other hand, in case of filter press, sludge should be introduced into the filter plate at high pressure, so only high pressure pumps can be used, and there is no compatibility of pumps, and the pumping life is shortened to maintain proper high pressure. . In addition, since the pressure flowing into the filter cannot be adjusted according to the type of sludge, there is a non-productive problem in that unnecessary time is wasted in order to increase and maintain the dewaterable pressure. It is difficult to expect high dewatering efficiency because the pressing force cannot be adjusted according to the sludge.

따라서 종래의 탈수장치는 전반적인 작업과정에서 작업자가 수시로 점검하여야 하며, 슬럿지에 내포된 날카로운 이물질에 의한 필터나 여과포의 손상이 자주 발생되어 경제적인 손실은 물론, 필터 또는 여과포를 갈아줘야 하는등 탈수작업이외에 간접적으로 수반되는 여러작업에 의해 작업 시간이 길어져 운전상의 비효율적인 문제점이 초래되었다. 또한 시멘트 슬럿지 등과 같이 부착, 고형화 현상이 일어나는 슬럿지나, 금속 및 비금속 연마 공장에서 배출되는 연마분, 스크랩 슬럿지등은 필터나 여과포를 손상시키게 되어 탈수처리가 불가능하여 슬럿지의 종류에 따라 선별하여 탈수작업을 수행할 수 밖에 없는 문제점이 있어왔다.Therefore, the conventional dewatering device should be inspected by the operator from time to time in the overall work process, and damage to the filter or filter cloth caused by the sharp foreign matter contained in the sludge is frequently caused, and economical loss, and the filter or filter cloth should be changed. In addition, the work time is prolonged by various tasks involved indirectly, resulting in an inefficient operation. In addition, sludge that adheres and solidifies, such as cement sludge, abrasives and scrap sludge discharged from metal and nonmetal polishing plants, can damage the filter or filter cloth. There has been a problem that can only be done.

따라서 본 발명은 상기한 문제점을 해결하기 위해 안출한 것으로써, 슬럿지의 종류에 구애됨이 없이 모든 종류의 슬럿지에 포함된 수분을 탈수하기 위한 탈수장치를 제공하고자 하는데 본 발명의 목적이 있으며, 탈수후 여과포에 압착된 케이크화 된 슬럿지의 자동 탈거장치 및 여과포의 자동세척장치를 부착하여 탈수처리과정의 전공정을 전자동화 하므로써 탈수시간의 단축 및, 탈수공정 또한 슬럿지에 함유된 수분의 자중에 의해 1차적으로 탈수시킨 후 슬럿지 내에 잔존하고 있는 잔여수분은 압축공기를 이용하여 2차에 걸쳐 탈수 시키므로써 탈수 효율을 높이고, 공기압을 이용 하므로써 슬럿지에 의한 여과포의 손상을 방지토록 하여 지속적으로 탈수작업이 수행되도록 하고자 하는데 다른 목적이 있다. 또한 본 발명은 슬럿지 농도에 따라 1단계 탈수시간을 조정 하므로써 많은양의 슬럿지를 단시간에 처리할 수 있으며, 저농도의 슬럿지 경우에도 농축조의 설치 없이도 탈수가 가능하도록 함으로써 설치비의 감소, 설치면적의 최소화 및 설비의 보수와 운영이 용이하도록 하는데 본 발명의 또다른 목적이 있다.Therefore, the present invention has been made to solve the above problems, to provide a dewatering device for dehydrating water contained in all kinds of sludge without regard to the type of sludge, there is an object of the present invention, dehydration After the automatic removal of the caked sludge pressed on the filter cloth and the automatic washing device of the filter cloth, the entire process of the dehydration process is fully automated, so that the dehydration time is shortened and the dehydration process is also caused by the weight of moisture contained in the sludge. After the first dehydration, the residual water remaining in the sludge is dehydrated through the secondary air using compressed air to increase the dewatering efficiency and to prevent damage of the filter cloth caused by the sludge by using air pressure. There is another purpose for doing so. In addition, the present invention can treat a large amount of sludge in a short time by adjusting the one-step dehydration time according to the sludge concentration, and even in the case of low concentration sludge, it is possible to dehydrate without the installation of the concentration tank to reduce the installation cost, minimize the installation area and Another object of the present invention is to facilitate the maintenance and operation of the equipment.

The sludge introduced into the upper chamber 130 is dehydrated by its own weight in one step. When the pressure in the upper chamber 130 due to the inflow of the sludge reaches a predetermined pressure (adjustable), the compressed air is passed through the air inlet 120. Inflow, secondary dehydration proceeds.

한편 상부챔버(130) 상면 일측에 형성된 공기 주입구(120)로 고압의 공기를 불어넣어 주기 위한 에어챔버(160)가 케이스(100) 일측에 고정장착된다.On the other hand, the air chamber 160 for blowing high-pressure air into the air inlet 120 formed on one side of the upper chamber 130 is fixedly mounted on one side of the case 100.

1,2단계 탈수가 완료되면 실린더(150)에 의해 상부챔버(130)가 상승하게 되고, 하우징(200) 일측 상면부에 고정된 구동모터(220)가 구동로울러(221)를 구동하고, 따라서 케이크화 된 슬럿지(2)가 부착된 여과포(210)가 상기 상부챔버(130)와 하부챔버(140) 사이를 빠져나와 이송된다. 여과포(210)가 이송되면서 공기분사노즐(230)에서 여과포(210)를 향해 공기가 분사되고 여과포(210)에 압착된 케이크(CAKE)화된 슬럿지(2)는 상기 공기분사노즐(230)에서 분사되는 공기에 의해 탈거되도록 되어 있다. 상기와 같이 여과포(210)에 공기를 분사하여 탈거되는 슬럿지를 완전하게 털어내기 위해 공기분사노즐(230)과 여과포(210)를 사이에 두고 마주보는 위치에 구동로울러(221)의 회전에 따라 연동되도록 체인등으로 연결된 스크레퍼(300)를 구비하여 여과포(210)에서 탈거가 시작되는 슬럿지를 완전하게 여과포(210)에서 털어내어 따로 구비된 슬럿지 수거함에 떨어뜨리도록 한다.When the first and second stage dehydration is completed, the upper chamber 130 is raised by the cylinder 150, and the driving motor 220 fixed to the upper surface of one side of the housing 200 drives the driving roller 221. The filter cloth 210 to which the caked sludge 2 is attached is transported out through the upper chamber 130 and the lower chamber 140. As the filter cloth 210 is transported, air is injected from the air spray nozzle 230 toward the filter cloth 210, and the cake-shaped cake sludge 2 compressed on the filter cloth 210 is sprayed from the air spray nozzle 230. It is to be removed by the air which becomes. In accordance with the rotation of the driving roller 221 in the position facing the air injection nozzle 230 and the filter cloth 210 in order to completely shake off the sludge removed by injecting air to the filter cloth 210 as described above. The scraper 300 is connected to a chain or the like so as to completely remove the sludge from the filter cloth 210 and start dropping it from the filter cloth 210 so as to drop the sludge collector.

이때 여과포(210)는 하우징(200) 일측에 고정된 구동로울러(221)와 타측에 고정된 종동로울러(222)에 착설되어 있고 하우징(200) 하단으로 고정된 지지로울러(223)에 의해 지지되면서 순환이송되도록 하며, 장시간 탈수처리작업이 진행되어 여과포(210)의 장력이 떨어지는 것을 대비하여 여과포(210)의 장력을 알맞게 맞춰주는 장력조절장치(224)가 하우징(200) 적정부위에 고정장착 되어 진다.In this case, the filter cloth 210 is installed in the driving roller 221 fixed to one side of the housing 200 and the driven roller 222 fixed to the other side, and supported by the support roller 223 fixed to the bottom of the housing 200. In addition, the tension control device 224 is fixedly mounted on the proper portion of the housing 200 to allow the circulation to be transported, and to prepare the tension of the filter cloth 210 in preparation for the drop of the tension of the filter cloth 210 due to the dehydration process for a long time. Lose.

한편 상기 공기분사노즐(230)에서 분사되는 공기에 의해 케이크화된 슬럿지(2)의 탈거가 완료된 후 구동로울러(221)에 의해 여과포(210)가 순환되어 타측으로 순환이송되면 물분사노즐(240)이 여과포(210)를 향해 물이 분사되어 상기 공기분사노즐(230)에 의해 케이크화된 슬럿지(2)가 탈거된 후 미세하게 여과포(210)에 압착되어 있는 불순물을 재차 떨어내고 여과포(210)의 틈새등을 세척하여 여과포(210)를 항상 깨끗하게 유지하도록 하고 있다.Meanwhile, after the removal of the cake sludge 2 is completed by the air spraying nozzle 230, the filter cloth 210 is circulated by the driving roller 221 and circulated to the other side. Water is sprayed toward the filter cloth 210 to remove the sludge 2 caked by the air spray nozzle 230, and then finely drop the impurities compressed in the filter cloth 210 again, and filter cloth 210 ) To clean the gaps and to keep the filter cloth 210 always clean.

한편 하부챔버(140)와 연통되면서 하방으로 상기 하우징(200)과 결합고정되는 드레인펜(250)이 구비되어 있어 슬럿지에서 탈수된 탈수여액을 집결하여 드레인펜(250) 전면부에 형성된 드레인배출구(260)를 통해 탈수여액은 집수조로 보내거나 재활용하게 된다.Meanwhile, a drain pen 250 is connected to the lower chamber 140 and fixedly coupled to the housing 200 downward to collect the dehydration filtrate dewatered from the sludge to form a drain outlet formed at the front of the drain pen 250 ( 260), the dehydration amount is sent to the sump or recycled.

상기와 같은 구성에 따라 본 발명의 작동상태를 상세히 설명한다.According to the configuration as described above will be described in detail the operating state of the present invention.

본 발명은 레미콘이나 흄관 공장에서 생성되는 시멘트 슬럿지나 혹은 도자기 생산시 발생되는 슬럿지, 세라믹 공장의 침전물 슬럿지나 폐수처리장에서 발생되는 슬럿지와 금속 및 비금속 연마공장에서 생성되는 연마분 스크랩 슬럿지나 각종 음식물 쓰레기등의 탈수가 가능한 슬럿지 탈수 처리장치로써, 본 발명의 탈수 처리과정은 2단계에 걸쳐 탈수가 처리되는바 슬럿지에 함유된 수분이 자중에 의해 탈수가 되는 단계와 압축공기의 압축에 의해 탈수되는 과정을 거치게 된다.The present invention is a cement sludge produced in a ready-mixed concrete or a fume pipe plant or a sludge produced in ceramic production, a sludge sludge produced in a ceramic plant or a sludge produced in a wastewater treatment plant, and a sludge scrap sludge produced in a metal and nonmetal polishing plant, or various food wastes. As a dewatering sludge dewatering treatment apparatus of the present invention, the dehydration treatment process of the present invention is dewatered in two stages, the water contained in the sludge is dehydrated by its own weight and the process of dehydration by compression of compressed air Going through.

먼저 물과 같이 혼합되어 있는 슬럿지가 슬럿지 탱크(도시하지 않음)에 저장되면 펌프(도시하지 않음)에 의해 슬럿지 탱크에서 슬럿지를 슬럿지 탈수처리장치(1)로 유동시키게 되는데, 도1에서 보는바와 같이 상부챔버(130) 상면에 구비된 슬럿지투입구(110)로 수분이 함유된 슬럿지가 투입된다.First, when the sludge mixed with water is stored in the sludge tank (not shown), the sludge is flowed from the sludge tank to the sludge dewatering treatment device 1 by a pump (not shown), as shown in FIG. Sludge containing moisture is introduced into the sludge inlet 110 provided on the upper chamber 130.

이렇게 투입된 슬럿지가 일정부위에 집중되어 투입되는 것을 방지하고, 상부챔버(130)에 고르게 분포될 수 있도록 하기 위해 상부챔버(130) 내부 상단에 슬럿지 분산장치(170)를 고정 지지하고 있는바, 이때 상기 슬럿지 분산장치(170)는 상방이 통공된 형상의 덕트(171)가 상부챔버(130) 내부를 횡간하면서 길게 형성되고 중앙의 덕트(171) 양측면에 덕트(172)가 복수개 연통되어 있어, 상기 슬럿지 분산장치(170)로 투입된 슬럿지는 중앙부의 덕트(171)를 따라 유동하면서 양측면으로 연통된 측면부의 덕트(172)를 따라 슬럿지가 유동된다. 이렇게 유동되는 슬럿지는 각각의 덕트(171)(172) 측하단면에 형성된 다수개의 배출구(173)를 따라 하방으로 낙하가 된다.In order to prevent the injected sludge from being concentrated at a predetermined part and to be evenly distributed in the upper chamber 130, the sludge dispersing device 170 is fixedly supported at the upper end of the upper chamber 130. The sludge dispersing device 170 is formed while the upper duct 171 of the through-hole is transversely formed inside the upper chamber 130 and a plurality of ducts 172 communicate with both sides of the central duct 171, The sludge injected into the sludge dispersing device 170 flows along the duct 171 of the central portion, and the sludge flows along the duct 172 of the side portions communicating with both sides. The sludge flowing in this way is dropped downward along a plurality of outlets 173 formed in the lateral side surfaces of the ducts 171 and 172.

이렇게 낙하되는 슬럿지에는 물이 공존하고 있는 상태이므로 물과 슬럿지는 덕트(171)(172)의 배출구(173)를 통해 자유낙하되면서 물은 여과포(210)를 통과하고, 슬럿지는 여과포(210) 위에 적재된다. 한편 여과포(210)를 통과한 수분은 하부챔버(140)를 통과하여 하우징(200)과 고정되어 있는 드레인팬(250)에 집수되어 드레인 배출구(260)를 통하여 집수조로 배수된다.Since water is present in the sludge that falls in this way, water and the sludge freely fall through the outlet 173 of the ducts 171 and 172, and the water passes through the filter cloth 210, and the sludge is on the filter cloth 210. Is loaded. Meanwhile, the water passing through the filter cloth 210 passes through the lower chamber 140 and is collected in the drain pan 250 that is fixed to the housing 200 and drained to the water collecting tank through the drain outlet 260.

한편 여과포(210)에 적재된 슬럿지의 양이 증가하면서 여과포(210)를 통과하는 물의 배수속도는 느려지고, 상부챔버(130)의 내압은 점차 증가하게 된다. 상부챔버(130)내의 압력이 일정압력에 도달하거나 슬럿지 유입이 일정시간 경과하면 슬럿지 이송용 펌프(도시하지 않음)가 정지하고, 상부챔버(130) 상단에 부착된 공기주입구(120)를 통하여 압축공기가 상부챔버(130)내로 유입되면서 2단계 탈수가 진행된다. 콤푸레샤(도시한지 않음)에서 생성된 압축공기는 에어챔버(160)를 거쳐 상부챔버(130)로 유입되는데 슬럿지의 종류에 따라 유입압력이 조정되어 탈수시간 단축은 물론 탈수효율을 증대 시킨다.Meanwhile, as the amount of sludge loaded on the filter cloth 210 increases, the drainage speed of the water passing through the filter cloth 210 becomes slow, and the internal pressure of the upper chamber 130 gradually increases. When the pressure in the upper chamber 130 reaches a predetermined pressure or when the sludge inflow elapses for a predetermined time, the sludge conveying pump (not shown) is stopped and compressed through the air inlet 120 attached to the upper chamber 130. As air flows into the upper chamber 130, two-stage dehydration proceeds. Compressed air generated in the compressor (not shown) is introduced into the upper chamber 130 through the air chamber 160. The inlet pressure is adjusted according to the type of the sludge to shorten the dehydration time and increase the dehydration efficiency.

1,2단계 탈수가 완료되면 자동적으로 상부챔버(130)내의 여압이 외부로 방출되고, 상부에 장착된 실린더(150)가 작동하면서 상부챔버(130)가 상승한다. 이때 구동모터(220)의 작동으로 체인(225)으로 연결된 구동로울러(221)와 스크래퍼(300)가 회전하고, 여과포(210)가 이동하면서 여과포(210)에 압착된 케이크화된 슬럿지(2)가 상부챔버(130)와 하부챔버(140) 사이를 빠져 나온다. 동시에 구동로울러(221) 하단에 설치된 공기분사노즐(230)에서 압축공기가 분사되어 여과포(210)에 압착된 슬럿지(2)를 여과포(210)로부터 이탈시키고, 이탈된 케이크화된 슬럿지(2)는 스크레퍼(300)에 의해 여과포(210)으로부터 완전히 탈거된다. 구동모터(220)는 후미의 슬럿지케이크(2)가 여과포(210)로부터 완전히 탈거될 때까지 작동하며, 공기분사노즐(230)과 여과포(210) 자동세척용 물분사노즐(240)은 구동모터(220)와 연동한다.When dehydration of the first and second stages is completed, the pressurization in the upper chamber 130 is automatically released to the outside, and the upper chamber 130 is raised while the cylinder 150 mounted on the upper side is operated. At this time, the drive roller 221 and the scraper 300 connected to the chain 225 by the operation of the drive motor 220 is rotated, the cake fabricated sludge (2) pressed on the filter cloth 210 while the filter cloth 210 is moved. Exits between the upper chamber 130 and the lower chamber 140. At the same time, compressed air is injected from the air spray nozzle 230 installed at the lower part of the driving roller 221 to separate the sludge 2 compressed on the filter cloth 210 from the filter cloth 210, and the caked sludge 2 that has been separated. Is completely removed from the filter cloth 210 by the scraper (300). The drive motor 220 is operated until the sludge cake 2 of the rear is completely removed from the filter cloth 210, and the air spray nozzle 230 and the filter cloth 210 for the automatic cleaning water spray nozzle 240 are driven motor. Link with 220.

여기서 물분사노즐(240)의 역할은 공기분사노즐(230)에서 분사된 압축공기가 슬럿지케이크(2)를 이탈 시킬 때 잔존한 미세 슬럿지 및 여과포 눈목 틈사이의 불순물 등의 제거와 더러워진 여과포(210)를 깨끗하게 세척하는데 있다. 또한 여과포(210)는 구동로울러(221), 종동로울러(222) 및 지지로울러(223)에 착설되어 이동한다.Here, the role of the water spray nozzle 240 is to remove the impurities, such as fine sludge and filter cloth remaining in the compressed air injected from the air spray nozzle 230 to leave the sludge cake (2) and dirty filter cloth (210) ) To clean. In addition, the filter cloth 210 is installed in the driving roller 221, the driven roller 222 and the support roller 223 to move.

한편 물분사노즐(240)에 의해 깨끗해진 여과포(210)가 하부챔버(140) 상부에 위치하면 상부챔버(130) 상면부에 장착된 실린더(150)가 작동하여 상부챔버(130)를 하강시키게 된다. 이렇게 하강된 상부챔버(130)는 도3에서 보는바와 같이 하부챔버(140)의 상단면과 접하게 되는데, 이때 상부챔버(130)의 하단면에 볼트(135)에 의해 고정된 고정부재(131) 내부에 몸체부(133)가 삽입되고 원형 돌출부(134)가 상기 고정부재(131) 표면상으로 원형 돌출부(134)가 돌출된다. 하부챔버(140)도 마찬가지로 하부챔버(140) 상단면을 따라 볼트(145)에 의해 고정되는 고정부재(141)내에 몸체부(143)가 삽입되고 고정부재(141) 표면상으로 약간의 돌출면(144)을 갖는 고무패드(142)가 구비되어 있어, 하강하는 상부챔버(130)의 원형 돌출부(134)와 하부챔버(140)의 돌출면(144)이 서로 만나면서 상호 압박을 가하게 되어 상하부챔버(130)(140)간의 기밀성을 유지할수 있게 된다.Meanwhile, when the filter cloth 210 cleaned by the water spray nozzle 240 is positioned above the lower chamber 140, the cylinder 150 mounted on the upper surface of the upper chamber 130 operates to lower the upper chamber 130. do. The lowered upper chamber 130 is in contact with the upper surface of the lower chamber 140, as shown in Figure 3, wherein the fixing member 131 fixed to the lower surface of the upper chamber 130 by the bolt 135 The body 133 is inserted therein and the circular protrusion 134 protrudes from the circular protrusion 134 onto the surface of the fixing member 131. Similarly, the lower chamber 140 is inserted into the fixing member 141 fixed by the bolt 145 along the upper surface of the lower chamber 140, and a slight protruding surface on the surface of the fixing member 141. Rubber pad 142 having a (144) is provided, the lower and upper circular chamber 134 of the upper chamber 130 and the projecting surface 144 of the lower chamber 140 meet each other and apply mutual pressure to the upper and lower chambers It is possible to maintain the confidentiality between (130) and (140).

이때 상부챔버(130)와 하부챔버(140) 사이에 위치한 여과포(210)를 상부챔버(130)의 원형 돌출부(134)와 하부챔버(140)의 돌출면(144)이 압박하면서 여과포(210)상에 존재하고 있는 슬럿지가 원형 돌출부(134)에 의해 양측으로 밀려나는 현상이 일어나게 되는바, 이것은 상부챔버(130)와 하부챔버(140)와의 압박시 여과포(210)상의 압박부위에 슬럿지 등이 존재할 경우 기밀성이 유지되지 못하는 점을 미리 방지하기 위한 것으로, 원형 돌출부(134)에 맞닿는 슬럿지(2)등을 상부챔버(130) 내,외측으로 밀어주는 역할을 함과 동시에 상호간의 기밀성을 유지시켜 주어 상부챔버(130)와 하부챔버(140)와의 기밀성을 확보함과 동시에 여과포(210)를 보호하도록 하기 위함이다.At this time, the filter cloth 210 is pressed while the circular protrusion 134 of the upper chamber 130 and the protruding surface 144 of the lower chamber 140 press the filter cloth 210 positioned between the upper chamber 130 and the lower chamber 140. The sludge existing in the upper side is pushed to both sides by the circular protrusion 134, which is the sludge in the pressing area on the filter cloth 210 when the upper chamber 130 and the lower chamber 140 is pressed. If present, to prevent the airtightness is not maintained in advance, and serves to push the sludge 2, etc. in contact with the circular protrusion 134 in the upper chamber 130, the outside and at the same time to maintain the mutual airtight This is to ensure the airtightness between the upper chamber 130 and the lower chamber 140 and to protect the filter cloth 210 at the same time.

이렇게 상부챔버(130)와 하부챔버(140)가 밀착되면 다시 슬럿지가 슬럿지투입구(110)를 통하여 슬럿지 분산장치(170)에 유입되어 상술한 바와 같은 작동을 반복,순환하게 된다.When the upper chamber 130 and the lower chamber 140 are in close contact with each other, the sludge flows back into the sludge dispersing device 170 through the sludge inlet 110 and repeats and circulates the operation as described above.

상술한 일련의 반복,순환 공정은 컨트롤유니트(도시하지 않음)에 의하여 전자동으로 작동되며, 모든 공정의 작동조건을 임의로 조정 및 설정이 가능하다.The series of repetition and circulation processes described above are operated automatically by a control unit (not shown), and the operating conditions of all processes can be arbitrarily adjusted and set.

따라서 본 발명에 의하면 슬럿지를 상부챔버에 투입한후 1단계로 수분이 함유된 슬럿지 자체의 자중에 의하여 탈수가 진행되고, 2단계로 여과포 상면에 누적된 슬럿지를 고압의 압축공기를 주입하여 압박 하므로써 슬럿지 내에 잔존하고 있는 잔여 수분을 탈수하는 2단계 탈수방식으로, 종전의 필터프레스 방식이나 여과포벨트에 의해 여과벨트끼리 압박하여 수분을 탈수하는 경우보다 탈수효율을 증대시키고, 단시간에 대용량의 처리가 가능하다. 특히 시멘트 등의 부착성 슬럿지 또는 금속 및 비금속 연마에 의해 생성되는 날카로운 이물질이 함유된 슬럿지 등은 여과포나 벨트 등에 손상을 입히게 되어, 종전의 탈수 방식으로 처리할 수 없는 것과는 달리 본 발명은 모든 종류의 슬럿지에 구애받지 않고 내포된 수분을 탈수할 수 있는 효과를 갖는다.Therefore, according to the present invention, after the sludge is put into the upper chamber, dehydration proceeds by the self-weight of the sludge containing water in the first step, and in the second step, the sludge accumulated on the upper surface of the filter cloth is injected by pressing high-pressure compressed air. It is a two-stage dehydration method that dehydrates the residual water remaining in the sludge.It can increase the dehydration efficiency and process a large amount of water in a short time than the case of dehydrating water by pressing the filter belts by the conventional filter press method or the filter cloth belt. Do. In particular, adhesive sludge such as cement or sludge containing sharp foreign substances produced by metal and non-metal polishing may damage the filter cloth or the belt and the like, and thus the present invention may not be treated by conventional dehydration. Regardless of the sludge, it can dehydrate the contained moisture.

또한 본 발명은 여과포에 부착된 슬럿지 제거장치도 종전의 타 설비에서 찾아볼 수 없는 2단계(1단계; 공기분사 이탈장치, 2단계; 물분사 세척장치) 처리방법을 채택 하였고, 슬럿지 부착면 반대 방향에서 세척하는 역세방법을 채택하여 완벽한 세척효과를 얻고 있다. 1단계 세척(슬럿지 이탈) 장치를 통과한 후 잔존하는 미세 슬럿지 및 여과포에 부착된 불순물을 2차 물분사노즐에서 제거 및 세척 하므로써 항상 청결한 여과포 표면을 유지하며, 탈수효율의 증대는 물론 여과포의 수명을 연장할 수 있다. 종전의 필터프레스나 벨트프레스의 경우 처럼 일정기간(시간) 탈수작업이 진행된 후 운전을 멈추고 작업자가 여과판이나 벨트여과포 등에 압착된 잔여 케이크 등을 탈거 또는 세척하는 작업이 필요 없으므로 본 발명은 간접적인 작업시간에 소요되는 잉여인력을 최대한 활용할 수 있고, 많은 양의 슬럿지를 단시간에 처리할 수 있는 효과가 있으며, 작업을 지속적으로 수행할 수 있는 효과가 있는 것이다.In addition, the present invention adopts a sludge removal device attached to the filter cloth is a two-step (1 step; air spray escape, 2 steps; water spray cleaning device) treatment method that can not be found in other facilities, the sludge attachment surface opposite Adopting backwashing method to wash in the direction, perfect cleaning effect is obtained. After passing through the 1st stage washing (slit release) device, the remaining fine sludge and impurities adhering to the filter cloth are removed and washed in the secondary water spray nozzle to keep the surface of the filter cloth clean at all times, and increase the dehydration efficiency and the life of the filter cloth. Can be extended. As in the case of conventional filter presses or belt presses, the operation is stopped after dehydration for a certain period of time (hours), and thus, the operator does not need to remove or wash the remaining cakes compressed on the filter plate or the belt filter cloth. It is possible to make the most of the surplus manpower required in time, to process a large amount of slots in a short time, and to carry out the work continuously.

또한 본 발명은 종전의 저농도 슬럿지의 탈수 처리작업시 농축조에서 먼저 슬럿지를 농축시켜 고농도화된 슬럿지를 탈수하는 탈수방식과는 달리 저농도의 슬럿지도 농축조 없이 탈수 처리가 가능하므로 농축시설, 부대설비 등이 필요없어 설비비를 절감할 수 있고, 탈수처리장치의 설치장소를 최소화하여 유효공간을 최대한 활용할 수 있다.In addition, the present invention, unlike the dewatering method of dewatering the high concentration of sludge by first concentrated in the thickening tank in the dehydration process of the conventional low concentration sludge, because the low concentration of the sludge can also be dehydrated without the concentration tank, such as a concentration facility, ancillary facilities, etc. It can reduce the equipment cost because it is not necessary and can make the most of the effective space by minimizing the installation place of the dehydration treatment device.

또한 전과정이 전자동으로 처리되므로 슬럿지 탈수처리장치의 운전의 편의성을 도모할 수 있으며, 슬럿지의 종류에 따라 탈수시간 및 가압력을 임의로 조정이 가능한 컨트롤씨스템을 채택하여 불필요한 탈수시간을 절약할 수 있으며, 탈수효율을 극대화 시킬 수 있는 것이다.In addition, since the whole process is handled automatically, the operation of the sludge dewatering treatment device can be facilitated, and the control system that can arbitrarily adjust the dewatering time and pressure according to the type of sludge can save unnecessary dehydration time. It will maximize the efficiency.
