Description

스크류프레스 탈수기{SCREW PRESS DEHYDRATOR}Screw press dehydrator {SCREW PRESS DEHYDRATOR}

본 발명은 하수 및 폐수 또는 가축분뇨와 음식물 처리시 발생하는 고형물의 여액을 분리하는 탈수기에 관한 것으로, 원통형 웨지와이어 타입의 스크린 내부에서 회전하는 제1 스크류에 의하여 고형물을 압착 탈수하여 배출구로 배출되면 제2 스크류에 의해 토출배관으로 이송되고 이송배관으로 압송되는 스크류 탈수기에 관한 것이다.The present invention relates to a dehydrator for separating the filtrate of solids generated during the treatment of sewage and wastewater or livestock manure and food, and when the solid is compressed and dehydrated by a first screw rotating inside a cylindrical wedge wire type screen and discharged to an outlet. It relates to a screw dehydrator that is transferred to the discharge pipe by the second screw and pressure-feeded to the transfer pipe.

고형물의 여액을 분리하는 탈수기에는 원심탈수기, 벨트프레스 탈수기, 필터프레스 탈수기 등이 있으나, 원심탈수기의 경우, 고속회전에 의한 원심력을 이용한 여액을 분리하는 방법으로 컴팩트하고, 밀폐형 구조라 악취발생이 적은 장점이 있으나, 고속회전에 의한 소음 및 진동이 크고, 유지보수비용 높고, 동력소모가 큰 단점이 있다.There are centrifugal dehydrator, belt press dehydrator, filter press dehydrator, etc. for separating the filtrate of solids, but in the case of centrifugal dehydrator, it is a method of separating the filtrate using centrifugal force by high-speed rotation. However, there are disadvantages such as high noise and vibration caused by high-speed rotation, high maintenance cost, and high power consumption.

벨트프레스 탈수기는 동력소모가 적은 장점이 있으나 물 사용량이 많고, 탈수효율이 낮은 단점이 있다. 필터프레스는 탈수효율은 우수한 편이나 제품가격이 비싸고, 운전조작 불편하고, 연속운전이 불가능하다는 단점이 있다.The belt press dehydrator has the advantage of low power consumption, but has the disadvantage of high water consumption and low dehydration efficiency. The filter press has excellent dehydration efficiency, but has disadvantages such as high product price, inconvenient operation, and continuous operation.

이에 반하여 스크류프레스 탈수기는 컴팩트한 밀폐형 구조로 탈수 효율이 우수하며, 동력소요가 적고, 연속운전이 가능하여 많이 사용하고 있다. On the other hand, the screw press dehydrator has a compact sealed structure, excellent dehydration efficiency, low power consumption, and continuous operation.

하지만 기존 스크류프레스 탈수기의 경우,However, in the case of the existing screw press dehydrator,

배출구에서 나오는 탈수된 고형물을 이송하기 위하여 별도의 이송컨베이어를 설치하거나 수집하여 운반하여야 하는 문제점이 있다. There is a problem in that a separate transport conveyor must be installed or collected to transport the dehydrated solids coming from the outlet.

이를 개선하기 위한 종래 기술로서, 도1과 같은 중국특허 CP201310396104A 나선압착기(螺旋壓搾機)가 있다. 상기 나선압착기의 경우, 투입구에서 유입된 고형물이 원통형 타공판 내에서 회전하는 스크류에 의해 이송되고, 나선압착기(스크류)와 일축인 배출구로 밀어내면서 압밀력으로 탈수하는 방식이라 별도의 컨베이어 없이 이송이 가능한 장점이 있지만, 도4와 같이 압력조절판(14)을 사용할 수 없어 탈수 효율이 낮은 문제점이 있다. As a prior art for improving this, there is a Chinese patent CP201310396104A spiral press as shown in FIG. 1. In the case of the spiral compactor, the solids introduced from the inlet are transported by a screw rotating in a cylindrical perforated plate, and dewatered by a compaction force while being pushed to a discharge port which is uniaxial with the spiral compactor (screw), so transfer without a separate conveyor is possible. Although there is an advantage, there is a problem that the dewatering efficiency is low because the pressure regulating plate 14 cannot be used as shown in FIG. 4.

또 다른 종래 기술로서는 도2와 같이 국내특허 10-1438684호 탈수기가 있다.As another conventional technique, there is a domestic patent 10-1438684 dehydrator as shown in FIG.

상기 탈수기는 가압실(500)을 가지고 있어 탈수 효율을 높일 수 있고, 회전익(620)으로 압송할 수 있도록 되어져 있다. 하지만, 슬러지와 같은 입자가 작은 고형물의 경우에는 배출구(120a, 120b)로 배출되지만, The dehydrator has a pressurization chamber 500 to increase dehydration efficiency, and is designed to be pressure-feeded to the rotor blade 620. However, in the case of solids with small particles such as sludge, they are discharged through the outlets 120a and 120b,

협잡물과 같은 비교적 큰 입자의 고형물의 경우에는 상기 배출구(120a,120b)로는 배출이 어려운 문제점이 있고, 도3의 배출구(120b)의 경우에는 물티슈 등의 엉킨 협잡물이 회전익(620)을 감싸아 배출구(120b)를 막아 배출이 원활하지 않는 문제가 발생한다.In the case of solids of relatively large particles, such as contaminants, it is difficult to discharge through the outlets 120a and 120b, and in the case of the outlet 120b in FIG. 3, entangled contaminants such as wipes wrap around the rotor blades 620 to discharge. By blocking (120b) occurs a problem that the discharge is not smooth.

상기 종래기술과 같은 문제점을 개선하고자 안출된 것으로, 제1 스크류(12)에 의해 1차로 가압 탈수되어 배출구(16)로 나온 고형물을 제2 스크류(17)를 통해 토출배관(18)과 이송배관(23)으로 고형물을 이송하면서 압밀력으로 2차 탈수하여 탈수 효율을 극대화하고 이송을 용이하게 고안하여 별도의 이송 컨베이어가 필요 없는 고효율 탈수기를 제공한다.It was devised to improve the same problems as the prior art, and the discharged pipe 18 and the transport pipe through the second screw 17 are discharged through the second screw 17 by first dehydrating the first pressure by the first screw 12 and dewatering the solid. (23) While conveying the solids to the secondary dehydration with a compaction force to maximize the dehydration efficiency and designed to facilitate the transfer to provide a high-efficiency dehydrator that does not require a separate transport conveyor.

A drain 15b for discharging the filtrate is formed.

따라서, 제1 스크류와 압력조절판(14)에 의해 1차 탈수되어지고, 1차 탈수된 고형물이 제2 스크류가 토출배관(18)속으로 고형물을 압송하므로서 이송 배관에서 2차 탈수가 가능하도록 함으로서 고효율 탈수가 가능하며, 별도의 이송 컨베이어 없이 이송이 가능한 장점이 있다.Therefore, the primary dehydration is performed by the first screw and the pressure regulating plate 14, and the primary dehydrated solid material is capable of secondary dehydration in the conveying pipe as the second screw presses the solid material into the discharge pipe 18. High-efficiency dehydration is possible, and there is an advantage of being able to transfer without a separate transfer conveyor.
