본 발명은 필터의 자기 청소기능을 갖춘 대용량 자동 여과 장치에 관한 것으로서, 특히, 구성이 간단하여 경제적이고 효율적인 필터 세척수단을 갖는 자동 여과 장치에 관한 것이다.The present invention relates to a large capacity automatic filtration device having a self-cleaning function of a filter, and more particularly, to an automatic filtration device having a simple and economical and efficient filter cleaning means.
본 발명과 관련된 종래기술로는 원통형 여과 카트리지를 유입조내에 다수 설치하여 유입되는 액체를 여과하는 여과 장치가 있는데, 이는 여과 카트리지에 불순물이 집적되면 여가 카트리지를 교환하는 방식으로서 여과 효율은 높으나 여과 카트리지를 교환할 때 경제적인 부담이 요구되며 여과작동을 중단하고 여과 카트리지를 교환해야 하므로 계속적인 여과동작을 담보할 수 없다는 문제점이 있다.Conventional technology related to the present invention includes a filtration device for filtering the incoming liquid by installing a plurality of cylindrical filtration cartridges in the inlet tank, which is a method of replacing the leisure cartridge when the impurities are accumulated in the filtration cartridge, the filtration efficiency is high but the filtration cartridge There is a problem in that the economic burden is required when replacing the filtration operation and the filtration cartridge must be stopped and the filtration cartridge must be replaced, so that the continuous filtration operation cannot be secured.
상기 종래기술의 문제점을 해결하기 위한 또다른 종래기술로서, 자동적으로 여과기의 세척기능을 갖는 여과 장치가 있는데, 상기 또다른 종래기술을 제 1 도를 참조하여 살펴보면, 제 1 도는 상기 또다른 종래기술의 동작상태를 나타내는 단면도로서 도면에서 1은 유입조, 2은 유출조, 3은 배출조, 4는 세척중인 여과기, 5는 여과중인 여과기, 6은 급수구, 7은 압력 게이지, 8은 솔레노이드 밸브, 9는 피스톤 어셈블리를 각각 나타낸다.As another conventional technology for solving the problems of the prior art, there is a filtration device having a washing function of the filter automatically, referring to another prior art with reference to Figure 1, Figure 1 is another prior art 1 is an inlet tank, 2 is an outlet tank, 3 is an outlet tank, 4 is a washing filter, 5 is a filtering filter, 6 is a water inlet, 7 is a pressure gauge, and 8 is a solenoid valve. And 9 represents the piston assembly, respectively.
상기 종래기술의 동작을 살펴보면, 유입조(1)에 들어온 액체는 여과중인 여과기(5) 내부로 진입된후 다시 여과중인 여과기(5)의 벽층을 방사상으로 투과하여 유출조(2)로 빠진다. 이때, 여과중인 여과기(5)에 여과입자 보다 큰 입자는 여과중인 여과기(5) 내부에 걸리며 여과된 불순물은 여과기(5)가 세척단계에 달할 때까지 계속 보족되어 여과기(5)의 내부에 집적된다.Looking at the operation of the prior art, the liquid entering the inlet tank 1 enters the inside of the filter (5) being filtered and then radially penetrates the wall layer of the filter (5) being filtered and exits into the outlet (2). At this time, the particles larger than the filter particles in the filter (5) under filtration is trapped inside the filter (5) during filtering, and the filtered impurities continue to be satisfied until the filter (5) reaches the washing step and accumulates inside the filter (5). do.
상기 여와중인 여과기(5)는 유입조(1)에 존재하는 그 상단부위가 개방되어 유체가 진입되며 하단부위는 배출조(3)에 연결되는데 배출조(3)와의 차단을 위해 밀폐된다.The filtration filter 5 is open in the upper end of the inlet (1) is the fluid enters and the lower end is connected to the discharge tank (3) is closed for blocking with the discharge tank (3).
여과동작중에 압력 게이지(7)에 의해 사전설정된 압력차에 이른 것이 감지되면 전자제어장치의 작동으로 급수구(6)로 유체가 유입되어 피스톤 어셈블리(9)를 상향이동시켜 상단의 유입구가 붕쇄되므로 액체의 진입이 차단되고 하단이 개방되어 여과기의 내부에 집적된 불순물이 유출조(2)내의 유체의 역류로 인하여 배출된다. 즉, 세척중인 여과기(4)의 상태로 되는 것이다.When the pressure gauge 7 detects a predetermined pressure difference during the filtration operation, the fluid flows into the water inlet 6 by the operation of the electronic control unit and moves the piston assembly 9 upwards to disintegrate the inlet at the top. The entry of the liquid is blocked and the lower end is opened so that impurities accumulated in the interior of the filter are discharged due to the backflow of the fluid in the outlet tank 2. In other words, the filter 4 being washed is in a state.
이와같이 종래기술에 의한 여과 장치는 여과작용 및 여과기의 세척작용을 각 여과기(4,5)가 조정된 압력 한계점을 기준으로 교번적으로 작동하게 되어 있다.As described above, the filtration device according to the prior art alternates the filtration action and the cleaning action of the filter with respect to the pressure thresholds at which the respective filters 4 and 5 are adjusted.
그런데, 상기한 종래기술은 여과기의 구성이 복잡하고 그에 따른 가격도 고가이어서 여과기의 교환시 사용자에게 적지않은 경제적인 부담을 주며, 유출조(2)내의 그리 크지않은 역류압으로 여과기를 세척하므로 여과기의 세척효율이 높지 않은 문제점이 있었다.By the way, the above-described prior art is a complicated configuration of the filter and the price is also high, thereby giving a considerable economic burden to the user when replacing the filter, and because the filter is washed by a small backflow pressure in the outlet tank (2) There was a problem that the washing efficiency is not high.
따라서, 본 발명은 상기 종래기술의 문제점을 해결하기 위하여 안출된 것으로서 간단하게 구성된 여과수단과 가격이 저렴하고 세척효율이 높은 자동 여과 장치를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a filtration means simply configured to solve the problems of the prior art and an automatic filtration device having a low cost and high washing efficiency.

A cylindrical body 20 connected to 40, a cover 11 fixed to the body 20 by a ring-shaped bolt (EYE BNW) 10, and a motor support 29 installed on the cover 11 The motor 30 is fixed to the motor 30, one end is connected to the motor 30 by the coupling 15 and the other end is fixed to the hub (HUB) 22 and the fixing table 34 to the motor in the inner center of the body 20 Impurity removal of the cylindrical filter 38 fixed to the rotating shaft 32 rotated by the 30, the annular filter support 39 provided on the inner wall of the body 20, and the cylindrical filter 38 It is installed by symmetrically rotating shaft 32 to be in close contact with the inner surface of the cylindrical filter 38 through the blade arm (BLADE ARM) 33 At least two washing brushes 17, a pressure gauge 14 connected to the inlet 35 and the outlet 36 of the body 20 and having a sensor 41 attached thereto, and a drain hole of the drain pipe 40. And an electronic controller 27 connected to the solenoid drain valve 26 connected to the pressure gauge 14 and the sensor 41 attached to the pressure gauge 14 and the solenoid drain valve 26 to control the filter cleaning operation and the drain operation. .
상기와 같이 구성된 본 발명의 전체동작을 살펴보면, 유입구(35)로 정수해야할 유체가 인입되면 인입된 유체는 원통 필터(38)내의 유입조(19)로 진입되고 유체압에 의해 원통 필터(38)를 거쳐 유출조(18)로 배출되면서 정수동작이 이루어지며, 정수된 유출조(18)내의 유체는 유출구(36)를 통해 외부로 배출되게 된다.Looking at the overall operation of the present invention configured as described above, when the fluid to be purified into the inlet (35) is introduced into the fluid introduced into the inlet tank 19 in the cylindrical filter 38 and the cylindrical filter 38 by the fluid pressure The water purification operation is performed while being discharged to the outlet tank 18, and the fluid in the purified outlet tank 18 is discharged to the outside through the outlet 36.
일정시간이 지나 원통 필터(38)에 불순물이 쌓이면 불순물은 원통 필터(38)의 통과저항으로 작용하게 되고 이에 따라 유입되는 유체의 압력이 일정하므로 유입조(19)내의 압력이 상승하게 된다. 유입조(19)내의 압력상승은 압력 게이지(14)에 측정이 되고 사전에 설정해 놓은 일정한 값 이상이 압력 게이지(14)에 측정되면 센서(41)가 동작하여 전자제어기(27)로 감지신호를 보내고 상기 전자제어기(27)은 상기 감지신호를 수신하여 모터(30)을 구동시키고 일정시간후에 솔레노이드 배수밸브(26)를 동작시켜 배수구(37)가 열리도록 한다.If impurities accumulate in the cylindrical filter 38 after a predetermined time, the impurities act as a passing resistance of the cylindrical filter 38 and the pressure in the inflow tank 19 is increased due to the constant pressure of the inflowing fluid. When the pressure rise in the inflow tank 19 is measured by the pressure gauge 14 and more than a predetermined value set in advance is measured by the pressure gauge 14, the sensor 41 operates to detect the detection signal by the electronic controller 27. The electronic controller 27 receives the detection signal to drive the motor 30 and operates the solenoid drain valve 26 after a predetermined time so that the drain hole 37 is opened.
모터(30)가 동작됨에 따라 회전축(32)이 회전하고 회전축(32)에 날개암(33)으로 연결된 세척브러시(17)가 원통 필터(38)에 밀착되어 회전하면서 원통 필터(38)에 집적된 불순물을 제거하게 되고 불순물은 배수조(24)에 진입되어 있다가 배수구(37)가 열림에 따라 배수관(40)을 통해 배출된다.As the motor 30 is operated, the rotating shaft 32 rotates, and the washing brush 17 connected to the rotating shaft 32 by the wing arms 33 is integrated with the cylindrical filter 38 while being in close contact with the cylindrical filter 38. The impurities are removed and the impurities enter the drainage tank 24 and are discharged through the drain pipe 40 as the drain hole 37 is opened.
원통 필터(38)에 집적된 불순물이 제거됨에 따라 유입조(19)내의 압력이 서서히 해지되면서 압력 게이지(14)에 검출되는 측정값도 낮아지게 되어 그 값이 사전에 설정된 일정값 이하로 낮아지면 센서(41)의 감지동작이 정지된다. 센서(41)의 감지신호를 받지 못하게 된 전자제어기(27)는 모터(30)를 정지시키고 솔레노이드 배수밸브(27)의 동작도 정지시켜 배수구(37)를 막음으로 원통 필터(38)의 세척동작이 끝나게 된다.As the impurities accumulated in the cylindrical filter 38 are removed, the pressure in the inlet tank 19 is gradually released, and the measured value detected by the pressure gauge 14 is also lowered. When the value is lowered below a predetermined predetermined value, The sensing operation of the sensor 41 is stopped. The electronic controller 27 that does not receive the detection signal of the sensor 41 stops the motor 30 and also stops the operation of the solenoid drain valve 27 to block the drain port 37 so as to clean the cylindrical filter 38. Will be over.
한편, 세척브러시(17)는 몸체의 규모에 따라 그 숫자를 늘려 부가하여 설치 가능하며, 수명을 다하여 교체가 필요할 경우 날개암(33)과 일체로 교환, 또는, 세척브러시(17)의 개별교환이 가능하도록 구성되어 교체시 경제적인 부담을 최소화 할 수 있다. 또한, 패킹(12)은 몸체(20)와 덮개(11) 사이의 누수를 방지하기 위하여 설치된 것이고 덮개(11)상의 안전밸브(28)는 비상용 압력해지용이다. 그리고, 퇴수밸브(25)는 본 발명의 전체 세척시 사용된다.On the other hand, the washing brush (17) can be installed by increasing the number according to the size of the body, and if necessary to replace the replacement of the wing arm (33), or replacement of the washing brush (17) individually if the replacement is necessary It is configured to be able to minimize the economic burden on replacement. In addition, the packing 12 is installed to prevent leakage between the body 20 and the cover 11 and the safety valve 28 on the cover 11 is for emergency pressure release. And, the discharge valve 25 is used in the entire cleaning of the present invention.

The central control unit 52 is composed of a one-chip microprocessor, and operating software is mounted in a memory inside the one-chip microprocessor.
모터구동부(53)는 상기 중앙제어부(52)의 제어를 받아 모터(30)로의 구동신호를 제공하며, 솔레노이드밸브 구동부(54)도 상기 중앙제어부(52)의 제어를 받아 솔레노이드밸브(26)의 동작신호를 제공하는 기능을 담당한다.The motor driving unit 53 provides a driving signal to the motor 30 under the control of the central control unit 52, and the solenoid valve driving unit 54 also receives the control of the solenoid valve 26 under the control of the central control unit 52. It is responsible for providing the operation signal.
제 4 도는 중앙제어부(52)의 메모리에 탑재된 본 발명의 제어 소프트웨어의 흐름도이며, 처리절차에 대한 상세한 설명은 상술한 본 발명의 동작설명과 동일하므로 상술한 설명에 갈음한다.4 is a flowchart of the control software of the present invention mounted in the memory of the central control unit 52, and the detailed description of the processing procedure is the same as that of the above-described operation of the present invention.
따라서, 상기한 바와 같이 구성되어 동작하는 본 발명은 종래의 기술에 비해 여과수단을 원통 필터(38)로, 여과수단의 세척수단을 세척브러시(17)로 구성하여 구성이 간단함은 물론 유지보수가 용이하며, 세척브러시(17)의 제작단가가 저렴하므로 경제적인 향상을 꾀할 수 있는 효과가 있다.Therefore, the present invention configured and operated as described above is simpler in configuration as well as maintenance by constituting the filtration means as the cylindrical filter 38, the washing means of the filtration means as the washing brush 17, compared to the prior art.
