Description

자동 햄머링 시스템Automatic hammering system

본 발명은 필터시스템의 필터에 끼인 이물질을 분리하는 필터 하우징에 대한 자동 햄머링 시스템에 관한 것이다.The present invention relates to an automatic hammering system for a filter housing for separating foreign matter caught in a filter of a filter system.

필터 시스템(Filter System)은 개발되어 상용화 된지가 오래고 필터 클리닝을 자동화시켜 운전중 클리닝을 가능하게 하는 백 워싱 시스템(Back Washing System)도 상용화 된지 오래이다.The Filter System has been developed and commercialized for a long time, and the Back Washing System, which automates the cleaning of the filter and enables cleaning during operation, has been available for a long time.

하지만 필터의 용도가 다양화되고 필터링을 해야 하는 이물질의 크기가 미세해지면서 필터 엘레멘트의 규격도 미세해졌기 때문에 필터가 플러깅되는 빈도와 백 워싱 빈도가 빈번해짐에 따라 필터 시스템의 구동 부위 마모에 따른 누설이 가속화되고 미세한 필터 엘레멘트에 끼인 이물질을 제거하기에는 백 워싱 만으로는 충분하지 못한 경우가 많다.However, as the use of the filter is diversified and the size of the foreign matter that needs to be filtered becomes smaller, the size of the filter element becomes smaller. Therefore, as the frequency of the plugging of the filter and the frequency of back washing become more frequent, Backwashing is often not enough to accelerate leaks and remove debris from the fine filter elements.

현재까지는 이물질을 제거하기 위해서는 전동공구나 임펙트 툴, 햄머를 이용하여 필터 하우징에 충격을 가하고 있으나 필터 하우징의 변형을 초래하게 되고 충격의 타이밍이 맞지 않아 적절한 효과를 기대하기 어렵다.Until now, in order to remove foreign substances, the impact is applied to the filter housing by using an electric tool, an impact tool, or a hammer, but it causes deformation of the filter housing, and it is difficult to expect a proper effect because the timing of the impact is not correct.

본 발명의 목적은 상기와 같은 단점을 해결하기 위하여 백 워싱이 이루어지는 동안 필터 하우징에 자동적인 충격을 가하여 물리적 충격파를 형성하여 클리닝 효율을 향상시키고 필터에 진동을 유발시켜 필터에 끼인 이물질이 쉽게 분리되도록 하며 궁극적으로는 안정적인 흐름 증대를 유도하여 필터 시스템의 구동 부위 작동 횟수를 감소시켜 구동부 마모를 예방하여 마모에 의한 누설가능성을 줄이는 자동 햄머링 시스템을 제공하고자 하는 것이다.An object of the present invention is to apply a physical shock wave to the filter housing during the back wash to solve the above disadvantages to form a physical shock wave to improve the cleaning efficiency and to cause the filter to vibrate to easily remove the foreign matter trapped in the filter The ultimate goal is to provide an automatic hammering system that reduces the likelihood of leakage due to wear by reducing the number of actuations of the drive area of the filter system by inducing a stable flow increase.

본 발명의 자동 햄머링 시스템은 필터 하우징을 중심으로 상부에 필터링 흐름용 볼 밸브와 백 워싱 흐름용 볼 밸브가 위치되고 하부에 필터링 흐름용 볼 밸브와 백 워싱 흐름용 볼 밸브가 위치되며 자동 햄머링은 에어 노커와 타이머, 솔레노이드 밸브로 이루어지고 클램프는 에어 노커에 용접되어 필터 하우징에 진동을 주게 되며 콘트롤 패널은 지정된 압력을 감지하여 백 워싱 신호가 발생하면 필터링 흐름용 볼 밸브를 닫고 백 워싱 흐름용 볼 밸브를 열며 동시에 상기 솔레노이드를 작동시켜 에어 노커에 의해 필터 하우징에 충격을 주어 백 워싱 흐름에 의해 필터의 외면에 부착된 이물질을 분리시켜 백 워쉬 배출구를 통하여 폐기 탱크로 보내게 구성된다.In the automatic hammering system of the present invention, the ball valve for the filtering flow and the ball washing flow are positioned at the upper part of the filter housing, and the ball valve for the filtering flow and the ball valve for the back washing flow are positioned at the bottom of the filter housing. Is composed of air knocker, timer and solenoid valve.The clamp is welded to the air knocker to vibrate the filter housing.The control panel senses the specified pressure and closes the ball valve for filtering flow when the backwashing signal is generated. Simultaneously operating the solenoid by opening a ball valve to impact the filter housing by an air knocker to separate foreign matter attached to the outside of the filter by the backwashing flow and send it to the waste tank through the backwash outlet.

본 발명을 첨부된 도면을 참조하여 하기에 설명한다.The present invention is described below with reference to the accompanying drawings.

도1 에는 본 발명의 자동 햄머링 시스템의 필터링 서비스 흐름이 도시되는데, 2 개의 필터 하우징(7)을 중심으로 상부에 필터링 흐름용 볼 밸브(1)와 백 워싱 흐름용 볼 밸브(2)가 위치되고 하부에 필터링 흐름용 볼 밸브(11)와 백 워싱 흐름용 볼 밸브(12)가 위치된다.Fig. 1 shows the filtering service flow of the automatic hammering system of the present invention, in which a ball valve 1 for filtering flow and a ball valve 2 for backwashing flow are located at the top centering on two filter housings 7. And the ball valve 11 for filtering flow and the ball valve 12 for backwashing flow are located in the lower part.

필터링 서비스 흐름은 볼 밸브(1)및(11)가 열리고 볼 밸브(2)및(12)가 닫힌 상태에서 이루어지며 하부의 볼 밸브(11)로 서비스 흐름이 들어와서 필터 하우징(7)속으로 들어가며 필터(8)를 지나 상부의 볼 밸브(1)를 거쳐 서비스 흐름이 나가게된다. 이때 서비스 흐름속에 있던 이물질은 필터(8)의 외면에 쌓이게 된다.The filtering service flow takes place with the ball valves (1) and (11) open and with the ball valves (2) and (12) closed, and the service flow enters the lower ball valve (11) into the filter housing (7). It enters and the service flow out through the filter 8 through the upper ball valve (1). At this time, foreign matter in the service flow is accumulated on the outer surface of the filter (8).

도2에는 본 발명의 자동 햄머링 시스템의 백 워싱 흐름이 도시되는데, 백 워싱 흐름은 볼 밸브(2)및(12)가 열리고 볼 밸브(1)및(11)가 닫힌 상태에서 이루어지며 상부의 볼 밸브(2)로 백 워싱 흐름이 들어와서 필터(8)속으로 들어가며 필터하우징(7)을 지나 하부의 볼 밸브(12)를 거쳐 백 워싱 흐름이 나가게 된다. 이때 필터(8)에 쌓여 있던 이물질은 백 워싱 흐름을 타고 폐기 탱크로 배출된다.2 shows a backwashing flow of the automatic hammering system of the present invention, the backwashing flow being achieved with the ball valves 2 and 12 open and the ball valves 1 and 11 closed and The back washing flow enters the ball valve 2 into the filter 8 and passes through the filter housing 7 through the lower ball valve 12 to exit the back washing flow. At this time, the foreign matter accumulated in the filter 8 is discharged to the waste tank by the back washing flow.

볼 밸브(1)및(11)는 콘트롤 패널(10)로부터 신호를 받아 솔레노이드 밸브가 부착된 액츄에이터를 통하여 작동 공기에 의해 열리고 닫히게 된다.Ball valves (1) and (11) receive signals from the control panel (10) and are opened and closed by the working air through an actuator with a solenoid valve.

볼 밸브(2)및(12)는 콘트롤 패널(10)로부터 신호를 받아 레귤레이터(9)와 루브리케이터(Lubricator)(13)를 통해 공급되는 작동 공기를 백 워싱을 위하여 솔레노이드 밸브가 부착된 액츄에이터를 통하여 작동시켜 열리고 닫히게 된다.The ball valves 2 and 12 receive a signal from the control panel 10 and are provided with a solenoid valve for backwashing the operating air supplied through the regulator 9 and the lubricator 13. It is actuated through the actuator to open and close.

자동 햄머링은 에어 노커(Air Knocker)(3)와 타이머(6), 솔레노이드 밸브(5)로 이루어지며 중요한 것은 필터 하우징 크기와 필터의 크기에 따라 에어 노커의 충격량을 결정해야 하며, 백 워싱 동안 몇회의 햄머링을 하도록 할 것이냐에 따라 작동주기를 지정할 수 있도록 가변폭이 충분한 타이머(6)를 선정해야 한다.Automatic hammering consists of an air knocker (3), a timer (6) and a solenoid valve (5). The important thing is to determine the impact amount of the air knocker according to the filter housing size and the filter size. Depending on how many hammerings are required, a timer (6) with sufficient variable width should be selected to specify the operating cycle.

에어 노커(3)는 방폭지역에서도 사용가능한 자동 햄머로서 사용된다.The air knocker 3 is used as an automatic hammer which can be used even in an explosion-proof area.

타이머(6)는 콘트롤 패널(10)로부터 백 워싱 신호를 받아 에어 노커 작동용 솔레노이드 밸브(5)를 필요한 횟수 만큼 열고 닫을 수 있게 제어할 수 있어야 한다.The timer 6 should be able to control the opening and closing of the air knocker operation solenoid valve 5 as many times as necessary by receiving the backwashing signal from the control panel 10.

솔레노이드 밸브(5)의 개폐신호는 반드시 콘트롤 패널(10)로부터 받게 하여 백 워싱과 동시에 에어 노커(3)가 작동되도록 해야 한다.The open / close signal of the solenoid valve 5 must be received from the control panel 10 so that the air knocker 3 is operated at the same time as the back washing.

콘트롤 패널(10)로부터 신호를 받지 않고 볼 밸브(2)및(12)의 솔레노이드 밸브에서 분지하여 사용할 수 있으나 액츄에이터의 공기 요구량에 따라 불가능할 수 도 있고 볼 밸브(2)및(12)의 작동에 악영향을 미칠 수 있으므로 삼가해야 한다.It can be used branched from the solenoid valves of the ball valves 2 and 12 without receiving a signal from the control panel 10, but may be impossible depending on the air demand of the actuator and may not be possible to operate the ball valves 2 and 12. It should be avoided as it may adversely affect it.

클램프(4)는 에어 노커(3)로 필터 하우징(7)에 직접 충격을 가하게 되면 필터 하우징(7)이 손상되므로 반드시 클램프(4)를 설치하고 클램프(4)에 에어 노커(3)를 용접시켜 충격을 분산시켜 필터 하우징(7)을 보호해야 한다.If the clamp 4 is directly impacted on the filter housing 7 with the air knocker 3, the filter housing 7 is damaged. Therefore, the clamp 4 must be installed and the air knocker 3 is welded to the clamp 4. The filter housing 7 must be protected by dispersing the impact.

솔레노이드 밸브(5)는 콘트롤 패널(10)로부터 백 워싱 신호를 받아 백 워싱과 동시에 에어 노커가 작동되도록 해야 한다.The solenoid valve 5 should receive a back wash signal from the control panel 10 so that the air knocker is operated at the same time as the back wash.

필터 하우징(7)은 필터(8)를 내장하고 있는 필터링 시스템의 본체이며, 필터(8)는 필터링 시키고자 하는 이물질을 포집한다.The filter housing 7 is the main body of the filtering system incorporating the filter 8, and the filter 8 collects foreign substances to be filtered.

상기와 같이 구성된 본 발명의 자동 햄머링 시스템은 백 워싱이 일어나는 시점에 맞추어 햄머링을 실시하여야 한다. 이를 위해서는 콘트롤 패널(10)의 백 워싱 신호를 에어 노커를 작동시키는 동력원인 작동 공기를 개폐시키는 솔레노이드 밸브(5)가 직접 받아 백 워싱과 동시에 자동 햄머링되게 한다.The automatic hammering system of the present invention configured as described above should be subjected to hammering at the time when backwashing occurs. To this end, the solenoid valve 5 which directly opens and closes the operating air, which is the power source for operating the air knocker, is directly received by the back washing signal of the control panel 10 to be automatically hammered simultaneously with the back washing.

또한 본 발명의 자동 햄머링 시스템은 자동 연속화 시키는 에어 노커를 사용하는데, 이는 인력으로 작동시키는 충격방법은 균일한 충격량과 충격주기를 표준화 할 수 없기 때문이다.In addition, the automatic hammering system of the present invention uses an air knocker for automatic continuation, since the impact method operated by manpower cannot standardize a uniform impact amount and impact period.

본 발명의 자동 햄머링 시스템은 작동주기를 가변화시킬 수 있는 타이머(6)를 설치하는데, 이는 일정한 충격주기를 유지하여 충격파를 연속적으로 발생시키고 필터(8)에 지속적인 진동을 준다. 또한 클램프(4)가 설치되고 그 위에 충격을 가하여 필터 하우징(7)을 보호하고 충격을 분산시킨다. 자동 햄머 구동용 작동 공기는 볼 밸브(1)(11)및(2)(12) 구동용 작동 공기가 아닌 별도의 작동 공기 헤더에서 공급되므로 공기 요구량의 불균형을 해소시킨다.The automatic hammering system of the present invention installs a timer (6) capable of varying the operating cycle, which maintains a constant shock period and continuously generates shock waves and gives continuous vibration to the filter (8). In addition, a clamp 4 is installed and shocked thereon to protect the filter housing 7 and disperse the impact. The actuating air for automatic hammer drive is supplied from a separate actuating air header rather than the actuating air for driving the ball valves (1) (11) and (2) (12), thus eliminating the imbalance in air demand.

본 발명의 자동 햄머링 시스템의 작동을 설명한다.The operation of the automatic hammering system of the present invention will be described.

정상적인 운전상태에서는 볼 밸브(2)및(12)가 닫히고 볼 밸브(1)및(11)가 열린 상태에서 흐름이 필터(8)를 통과하여 빠져 나가고 흐름 중의 이물질이 필터(8)의 외면에 포집되며 이물질에 의해 필터의 오픈 면적이 감소되면 압력(△P)이 증가한다.In the normal operation state, the ball valves (2) and (12) are closed, and the flow of the fluid flows out through the filter (8) with the ball valves (1) and (11) open, and foreign matter in the flow flows to the outer surface of the filter (8). As the open area of the filter is collected by the foreign matter, the pressure DELTA P increases.

콘트롤 패널(10)에서 지정된 압력(△P)을 감지하여 백 워싱 신호가 발생하여 볼 밸브(1)및(11)는 닫히고 볼 밸브(2)및(12)는 열리면서 백 워싱 흐름에 의해 필터(8)의 외면에 부착된 이물질을 분리시켜 백 워쉬 배출구를 통하여 폐기 탱크로 보내진다.The control panel 10 senses the specified pressure DELTA P to generate a backwash signal, which causes the ball valves 1 and 11 to close and the ball valves 2 and 12 to open while the filter ( Foreign substances attached to the outer surface of 8) are separated and sent to the waste tank through the backwash outlet.

여기에서 백 워싱 신호를 콘트롤 패널(10)로부터 동시에 받아 백 워싱이 이루어질 때 자동 햄머링으로 필터 하우징(7)에 충격을 가하면 필터(8)에 미세한 진동을 발생시키고 백 워싱 흐름에 충격파를 유발시켜 클리닝 효과를 증대시키게 된다.Here, when the back washing signal is simultaneously received from the control panel 10 and the back washing is performed, impacting the filter housing 7 with automatic hammering generates fine vibration in the filter 8 and causes shock waves in the back washing flow. This will increase the cleaning effect.

이렇게 되면 부가적으로 볼 밸브(1)(11)및(2)(12)의 작동 횟수를 감소시켜 설비내구성을 증가시키게 되고 흐름의 량도 안정적으로 증대된다.This additionally reduces the number of actuations of the ball valves (1) (11) and (2) (12) to increase plant durability and increase the amount of flow stably.

상기에 언급한 바와 같이 본 발명의 자동 햄머링 시스템은 필터 하우징(7)에 충격을 가하여 백 워싱 흐름에 충격파를 유발시키고 필터(8)에 진동을 유발시켜 클리닝 효율을 향상시키기 위한 에어 노커(3)가 필터 하우징(7)에 충격을 가할 때 충격을 필터 하우징(7)에 분산시켜 필터 하우징(7)의 변형을 방지시킨다.As mentioned above, the automatic hammering system of the present invention imparts a shock wave to the backwashing flow by shocking the filter housing 7 and causing vibration to the filter 8 to improve cleaning efficiency. When the impact on the filter housing 7 distributes the impact to the filter housing 7 to prevent deformation of the filter housing 7.

에어 노커(3)를 용접시켜 고정시키기 위한 클램프(4)와 에어 노커(3)의 동력원으로 사용되는 작동 공기를 공급,차단하는 솔레노이드 밸브, 콘트롤 패널(10)로부터 백 워싱 신호를 받아 백 워싱 시작과 동시에 적정 횟수로 솔레노이드 밸브(5)를 개폐하도록 조정하는 타이머(6)를 설치하여 필터 시스템의 백 워싱시 백워싱 클리닝 효율을 향상시켜 안정적인 흐름 증가에 따른 필터 시스템의 구동부위 마모를 줄이고 마모에 따른 누설 방지와 설비수명 연장을 가능케 한다.Backwashing is started by receiving backwashing signals from the clamp 4 for welding and fixing the air knocker 3 and the solenoid valve and control panel 10 that supply and block the working air used as a power source of the air knocker 3. At the same time, the timer 6 for adjusting the opening and closing of the solenoid valve 5 at an appropriate number of times is installed to improve the backwashing cleaning efficiency during the backwashing of the filter system, thereby reducing the wear of the driving part of the filter system due to the stable flow increase and To prevent leakage and to extend the service life of the equipment.

실제로 유공 FCC 공장의 RHDS 공정 피드 필터(필터 크기 25 μ )의 16 Pair 에 본 발명의 자동 햄머링 시스템을 시험 적용한 결과 10% 정도의 흐름 증대, 백 워싱 주기 시간당 2 내지 3 회 감소의 성과를 보았으며 전체 96 Pair 에 대하여 본 발명의 자동 햄머링 시스템을 확대 적용할 예정이며 HOU 공장 VRDS 피드 필터에도 적용 가능하다.In fact, RHDS process feed filters from perforated FCC plants (filter size 25 μ The test results of the automatic hammering system of the present invention on 16 pairs of) showed a flow increase of about 10% and a reduction of 2 to 3 times per hour of backwashing cycles. It will be extended to HOU factory VRDS feed filter.

본 발명의 자동 햄머링 시스템은 필터 플러킹에 의한 차지업 보틀 넥크(Charge-Up Bottle Neck)를 해소하였고, 지금까지 충격을 가하기 위하여 운전원이 수작업으로 햄머링 하던 방법을 자동화시킴으로써 운전인력 손실을 방지하였으며 지금까지 필터의 잦은 막힘에 따른 과도한 횟수의 백 워싱으로 필터 구동부 마모에 따른 누설 횟수를 획기적으로 감소시켰고 과도한 햄머링에 의한 필터 하우징 변형을 근본적으로 방지할 수 있다.The automatic hammering system of the present invention eliminates the charge-up bottle neck due to filter plugging, and prevents the loss of operation manpower by automating the method by which the operator manually hammers in order to apply an impact. Up to now, excessive number of back washes due to frequent clogging of the filter has drastically reduced the number of leaks due to the wear of the filter drive, and it is possible to fundamentally prevent the filter housing deformation due to excessive hammering.
