Description

싸이클론식 연속여과기의 자동 역세 장치{Cyclone system analong filter auto backwash unit}Cyclone system analong filter auto backwash unit

본 발명은 유체(액체)를 연속적으로 여과하면서 여과 필터망통을 자동으로 청소해주는 싸이클론식 연속 여과기의 자동 역세장치에 관한 것이다.The present invention relates to an automatic backwashing device of a cyclone continuous filter which automatically cleans the filtration filter tube while continuously filtering the fluid (liquid).

일반적으로 여과 필터망통에 액체를 통과시켜 여과하는 과정에서 필터망통이 오물에 의해 더럽혀질 때는 필터망통을 교체하거나 주기적인 청소(또는 역세)를 해주지 않으면 안되는데 이때 필터나 필터망통을 교체할시는 교체용 예비 필터나 필터망통을 비치 해야 할 필요성이 있고 또한 교체할때는 이에 따른 인건비와 여과 과정의 조업중단 등의 손상이 수반되므로 가능하면 여과작업을 연속적으로 수행하면서 필터망통을 청소 할 수 있도록 함이 바림직한 것이다. 따라서 연속적으로 여과작업을 수행하면서 여과 필터망을 청소 할려면 예비 여과기를 별도로 설치하여 교대로 청소로 해임야 하게 때문에 이에 따른 경제적인 과부담이 있는 것이다.In general, when the filter canister is contaminated by dirt in the process of passing the liquid through the filter canister, the filter canister should be replaced or periodically cleaned (or backwashed). It is necessary to have a spare filter or filter box, and when it is replaced, the labor cost and the operation of the filtration process are damaged. Therefore, if possible, the filter box can be cleaned while performing filtration continuously. It is right. Therefore, in order to clean the filtration filter network while continuously performing the filtration work, there is an economic overload according to this, because a separate preliminary filter must be installed and replaced by cleaning.

이러한 문제점을 해결하고자 근래 개발된 자동 역세 필터기가 공지된 바 있으나 이는 모터나 공기의 압력을 이용하여 필터망통이나 역세 배출구를 회전 내지 이동시키므로서 자동역세가 가능 하도록 하고 있으나 이와 같은 장치들은 다량의 역세수 배출로 인한 원수(또는 원액)이용율의 저하 및 고장율의 증가등의 문제점이 있을뿐만 아니라 이러한 자동 역세기의 원리는 필터망통의 여과수 측에 있는 찌꺼기 배출구를 조정한후(여과원수와 외부와의 압력 차이를 이용하여) 여과찌꺼기를 외부로 배출시키는 방법을 사용 하기 때문에 여과 필터망이 완전히 청소 되지 않고 순간적인 압력 변화로 말미암아 여과 필터망이 손상을 입게되는 폐단이 있었던 것이다.Recently, an automatic backwash filter has been developed to solve this problem, but this enables automatic backwashing by rotating or moving the filter barrel or backwash outlet by using a motor or air pressure. Not only are there problems such as lower raw water (or undiluted) utilization rate due to the discharge of water and increased failure rate, but also the principle of automatic backwashing is that after adjusting the waste outlet on the filtered water side of the filter tube (filter pressure from outside) By using the method of draining the filter debris to the outside, the filter network was not completely cleaned, and there was a closed end that caused the filter network to be damaged by the instantaneous pressure change.

또한 일반적인 싸이클론식 입자제거 장치는 유체속에 함유된 입자와의 비중차이 를 이용 하므로 이는 주로 기체용 입자 제거장치인 집진기용으로 사용되고 있는 실정 것이다. 따라서 액체용 싸이클론식 입자 제거장치는 원심력을 이용하여 처리하게 되므로는 유속의 한계에 따라 비교적 큰 입자만 제거 가능하게 때문에 하수처리나 폐수처리시 물속의 함유된 모래 등의 큰입자만 제거 하는 전처리용으로 사용되고 그 외에는 사용 할 수 없는 결점이 있었던 것이다.In addition, since the general cyclone particle removal device uses the specific gravity difference with the particles contained in the fluid, it is mainly used for the dust collector which is the gas particle removal device. Therefore, since the cyclone-type particle removal device for liquids is processed by centrifugal force, it is possible to remove only relatively large particles according to the limitation of the flow rate, and thus pretreatment to remove only large particles such as sand contained in water during sewage treatment or wastewater treatment. There was a flaw that could be used for other purposes.

본 발명은 이상의 결점을 해결하고자 발명 한 것으로 본 발명의 요지는 일반적인 싸이클론 장치에서 제거하지 못하는 미세입자를 여과 필터망통에 의해서 완벽하게 제거함과 동시 여과중에 있는 필터망통의 청소과정에 있어 여과 필터망의 손상이 생기지 않게 함과 동시 역세수 배출구을 조정하여 원수 (또는 원액)의 이용율을 높히 하면서 연속적인 여과 및 역세가 가능게 한것이다.The present invention has been made to solve the above-mentioned shortcomings, and the gist of the present invention is to completely remove the microparticles that cannot be removed in a general cyclone apparatus by the filtration filter network, and to filter the filtration filter network during the filtration process. It is possible to make continuous filtration and backwashing while increasing the utilization rate of raw water (or stock solution) by preventing back damage and adjusting the simultaneous backwash water outlet.

여과기몸체(1)의 주벽상부 일측에는 여과원수유입구(2)가 형성되고 하측에 형성된 호퍼(1')의 하측에는 찌꺼기 배출구(3)가 형성되고 덮개판(6)의 중심부에는 상부씰(11)을 개재하여 설치된 구동모터(9)의 회전축(7)이 설치되고 회전축(7)의 하부에는 공실(5)내에 설치된 여과 필터망통(4)의 중심부가 끼움설치된 상태에서 그 하부에는 여과수 배출관을 겸한 하부회전축(8)이 하부씰(10)을 개재하여 호퍼(1')의 중심부에 끼움 설치되고 호퍼(1')의 하부 일측에는 찌꺼기 배출구(3)가 설치된 구조이다.A filtration raw water inlet 2 is formed at one side of the upper wall of the filter body 1, and a waste outlet 3 is formed at a lower side of the hopper 1 ′ formed at the lower side, and an upper seal 11 is formed at the center of the cover plate 6. In the state where the rotary shaft 7 of the drive motor 9 installed through the center of the filtration filter net 4 installed in the vacant space 5 is fitted to the lower portion of the rotary shaft 7, The lower rotary shaft 8 also serves to be fitted to the center of the hopper 1 'via the lower seal 10, and the waste outlet 3 is installed at one lower side of the hopper 1'.

그리고 도 3은 본발명의 별도실시예로서 여과수 배출관을 겸한 하부 회전축(8)에는 하부씰(10)을 개재시켜 여과수 배수구(2')의 내단이 연결되고 이의 외단부는 호퍼(1')의 일측벽에 토출되고 여과필터망통(4)의 내부에는 역세 펌프(15)의 역세수 유입구(13)에 연결된 송수관(15')이 설치되어 있으되 이의 선단에는 역세슬리트(노즐)(14)가 설치되고 여과수 배수구(2')과 역세펌프(15) 사이에는 환수관(15")이 설치된 것이다.And Figure 3 is a separate embodiment of the present invention is connected to the inner end of the filtration water drain (2 ') through the lower seal 10 through the lower rotary shaft (8) also serves as a filtration water discharge pipe and its outer end of the hopper (1') A water pipe 15 'is discharged to one side wall and connected to the backwash water inlet 13 of the backwash pump 15 at the inside of the filtration filter net 4, and at the front end thereof, a back slit (nozzle) 14 is provided. A return pipe 15 "is installed between the filtered water drain 2 'and the backwash pump 15.

이상과 같이 구성된 본 발명은 싸이클론식 연속여과기의 자동 역세장치 인바 이를 실시할시는 도 1에 표시한 바와 같이 여과기몸체(1)의 측면에 형성된 여과 원수유입구(2)로 유입된 여과 원수는 여과필터망통(4)을 통해 통상의 여과작용을 한후 여과된 여과수는 여과수 배출관 겸 하부 회전축(8)을 통해 여과수 배출구(2')로 배출되고 여과작용에 의해 여과필터망통(4)의 주벽에 포집된 찌꺼기는 여과 필터망통(4)이 구동모터(9)에 의해 회동될 때 생기는 원심력에 의해 분리 되는 것인바 이의 분리 현상은 여과원수속에 함유된 입자(찌꺼기)는 물과의 비중차이와 원심력에 의해 무거운 입자는 회전하는 여과필터망통(4)의 접선방향으로 (원심력의 작용하는 방향)선회 하면서 여과 필터망통(4)에서 떨어져 나가게 되므로 여과 필터망통(4)은 역세 방향에서 청소되어진다.In the present invention configured as described above, when performing the automatic backwashing device of the cyclone continuous filter, as shown in FIG. 1, the filtered raw water introduced into the filtering raw water inlet 2 formed at the side of the filter body 1 is After normal filtration through the filter filtration network (4), filtered filtration water is discharged through the filtration water discharge pipe and the lower rotary shaft (8) to the filtration water outlet (2 ') and the filtration to the main wall of the filtration filter network (4) The collected debris is separated by centrifugal force generated when the filtration filter tube 4 is rotated by the driving motor 9. The separation phenomenon is that the particles contained in the filtration source are different from specific gravity and water centrifugal force. As a result, the heavy particles are pulled away from the filter bag 4 while turning in the tangential direction of the rotating filter bag 4 (the action of the centrifugal force), so that the filter bag 4 is cleaned in the backwash direction. Eojinda.

그리고 여과 원수 유입구(2)는 도 2에 표시된 바와 같이 여과기몸체(1)의 측면에서 접선방향으로 설치되어 있어 여과원수는 접선방향으로 흘러들어가게 되며 이때 생기는 나선 회류에 의해 여과원수에 포함 되어 있는 찌꺼기는 원심력에 의하여 여과기 몸체(1)의 공실(5) 바깥쪽으로 회류하면서 공실 하부로 침강 하여지므로 찌꺼기의 제거 효율을 높힐 수 있고 아울러 여과필터망통(4)에 의해 여과되는 찌꺼기의 양을 줄여 주므로서 여과 속도를 더욱 항상시킬수 있게 된다.And the filtration raw water inlet (2) is installed in the tangential direction on the side of the filter body (1) as shown in Figure 2 so that the filtration raw water flows in the tangential direction and the residue contained in the filtration raw water by the spiral flow generated at this time Since it is settled to the lower part of the vacant space while returning to the vacancy (5) of the filter body (1) by centrifugal force, it is possible to increase the removal efficiency of the debris and to reduce the amount of debris filtered by the filtration filter tube (4). It is possible to make the filtration rate even more constant.

즉 여과 원수의 접선의 흐름 방향과 같은 방향으로 여과필터망통(4)을 회전시키면 여과필터에서 분리된 찌꺼기는 접선의 흐름 방향과 같은 방향으로 흐르게 되고 회전되는 여과 필터망통(4)의 원심력작용으로 공실(5)내부에서 바깥쪽으로 회류하면서 하부로 침강 되어져서 찌꺼기배출구(3)로 배출하게 된다. 또한 여과 필터망통(4)이 회전 할 때 이 필터망으로 통과하는 물속에 함유된 미세 입자는 충돌에 의해 여과 필터망통(4) 외부로 튕겨 나와 여과원수의 접선의 흐름의 방향과 같은 방향으로 흐르는 여과찌꺼기와 함께 찌꺼기 배출구(3)로 배출된다. 따라서 여과 필터망통(4)의 기능은 여과기능, 원심력에 의한 역세기능, 그리고 빠른 회전력으로 생기는 입자와의 충돌기회를 늘리는 기능 등의 복합적인 기능을 하여 이 기능에 의해 여과 및 역세 효율을 향상시킨다.In other words, when the filtration filter net 4 is rotated in the same direction as the tangential flow of the filtration raw water, the debris separated from the filtration filter flows in the same direction as the tangential flow and is driven by the centrifugal force of the filtration filter net 4 which is rotated. The inside of the vacancy (5) is settled downward while returning to the outside and discharged to the waste outlet (3). In addition, when the filtration filter tube 4 rotates, the fine particles contained in the water passing through the filter network bounce out of the filtration filter network 4 by collision and flow in the same direction as the tangential flow of the filtration raw water. It is discharged to the waste outlet (3) together with the filter waste. Therefore, the filtration filter net tube 4 has a complex function such as a filtration function, a backwashing function by centrifugal force, and a function of increasing a collision chance with particles generated by rapid rotational force, thereby improving the filtration and backwashing efficiency. .

그리고 공실(5)의 하부로 모인 찌꺼기는 찌꺼기 배출구(3)를 통해여 외부로 배출되어 지는 것이나 이때 찌꺼기 배출구(3)에 배출량 조정을 위해 배출밸브를 설치하여 이를 조정하면 여과원수의 이용율을 높힐 수 있고 또한 배출되는 찌꺼기의 농도를 조절할 수 있으므로 액체속의 원료 찌꺼기를 회수 할 경우는 이의 농도를 조절할수 있다.And the waste collected in the lower part of the vacancy (5) is discharged to the outside through the waste outlet (3), but at this time to install the discharge valve for adjusting the discharge in the waste outlet (3) to increase the utilization rate of the filtered water It is also possible to control the concentration of wastes discharged, so that the concentration of wastes can be controlled when recovering the raw wastes in the liquid.

그리고 제 3도의 별도실시예는 제 1도의 처리 방법과 동일하나 역세수 유입구(13)를 추가 설치하여 정밀 여과나 고점도 유체 처리시 여과 필터망통(4)의 완벽한 세정을 위하여 역체수 유입구(13)에 높은 압의 역세 펌프(15)를 장착하거나 압력 유체를 주입하면 역세 슬러트(14)에서는 고압 역체수를 분사시켜 여과필터망통(4)을 완벽하게 세정할수 있게 된다.In addition, the separate embodiment of FIG. 3 is the same as the treatment method of FIG. 1, but the backwash water inlet 13 is additionally installed so that the backwash water inlet 13 may be completely cleaned for fine filtration or high-viscosity fluid treatment. When a high pressure backwash pump 15 is mounted or a pressure fluid is injected, the backwash slut 14 may inject high pressure backwash water to completely clean the filtration filter net 4.

이상과 같이 본 발명을 기존의 싸이클론식 입자 제거 장치에서 제거할 수 없는 미세한 입자를 완벽하게 제거 할 수 있고 또한 기존의 액체 여과기와는 달리 원심력에 의해 찌꺼기를 청소하게 되므로 역세 배출수의 사용량을 절감할 수 있을뿐만 아니라 찌꺼기 배출밸브의 조절에 따라 찌꺼기나 원료를 조절 배출되게 하였기 때문에 원액의 이용율을 높힐 수 있고 폐수배출량을 줄여 처리 비용을 절감하수 있을 뿐만아니라 연속 여과와 연속 청소가 가능하므로 여과속도 및 효율을 증가 할 수 있고 또한 여과 장치가 입체 원통형이므로 설치면적을 최소화 할 수 있어 산업적으로 크게 기여할 수 있는 것이다.As described above, the present invention can completely remove the fine particles that cannot be removed from the existing cyclone-type particle removal device and, unlike the conventional liquid filter, cleans the residue by centrifugal force, thereby reducing the amount of backwash effluent. Not only can it be done, but the waste or raw materials are controlled and discharged according to the control of the waste discharge valve, so that the utilization rate of the raw liquid can be increased, and the waste water discharge amount can be reduced, and the treatment cost can be reduced. And it can increase the efficiency and also because the filtration device is a three-dimensional cylindrical can minimize the installation area can greatly contribute to the industry.
