The present invention provides a continuous filtration apparatus for liquid type substances which improves the filtration efficiency by allowing the filter to be washed even during filtration treatment. It is about.
일반적으로, 산업분야에서는 물이나 기름등의 액상형태 물질을 냉각이나 윤활작용등의 용도로 사용하게 되므로서 이들이 불순물에 의해 오염되게되므로 이를 별도의 여과장치로서 여과토록 하므로서 환경오염을 방지함과 동시에 기구의 원활한 작동과 양질의 제품을 생산할 수 있도록 하고 기구의 수명을 연장할 수 있도록 하게 되는바, 이러한 용도로 사용되는 지금까지의 여과장치는 여과처리중에는 여과망에 걸러지는 불순물을 제거할 수 없어 계속되는 여과처리 과정에서 불순불이 여과망에 쌓이게 되므로서 여과효율이 떨어졌으며 또, 이러한 불순물을 제거하기 위해서는 여과처리를 중단하여야 하기 때문에 이에따른 많은 시간과 비용이 소요되었으며, 여과장치의 청소 및 세척에 사용된 여과제와 여과포는 이로인한 환경오염의 원인이 되었다.In general, in the industrial field, liquid-type substances such as water or oil are used for cooling or lubrication, so that they are contaminated by impurities, so that they are filtered by a separate filtering device, thereby preventing environmental pollution. As a result, it is possible to operate the apparatus smoothly, to produce high quality products, and to extend the life of the apparatus. Until now, the filtration apparatus used for this purpose cannot remove impurities filtered through the screen during the filtering process. As the impurities accumulate in the filtering network during the filtration process, the filtration efficiency is reduced. Also, in order to remove such impurities, the filtration process has to be stopped. Therefore, it takes a lot of time and money. Filters and Filter Cloths Caused Environmental Pollution .
본 고안은 이와같은 지금까지의 문제점을 해결하기 위한 것으로 여과가 되는 동안에도 불순물의 세척 및 청소를 쉽게 할 수 있도록 하여 여과효과를 증대시킬 수 있는 것으로서, 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention is to solve such problems so far as to facilitate the washing and cleaning of impurities even during the filtration to increase the filtration effect, described in detail with reference to the accompanying drawings as follows. same.
유입구(2)와 유출구(3)를 갖는 하우징(1)의 유도로(4)내에 필터테(13)를 설치한 것에 있어서, 하우징(1)의 말단부에 고정환턱(6)으로 구획되는 압력실(26)을 구비하여 밀폐판(12)으로 밀폐시키고, 압력실(26)에 배출구(7)를 연통설치하되, 배출구(7)에 구동부(9)로 개폐되는 밸브(8)를 설치하여 유입구(2)에 설치되는 압력감지센서(10)와 전선(11)으로 구동부(9)를 접속한다.In the case where the filter frame 13 is installed in the induction path 4 of the housing 1 having the inlet port 2 and the outlet port 3, the pressure chamber is partitioned by the fixed ring jaw 6 at the distal end of the housing 1. (26) and sealed with a sealing plate (12), the outlet port 7 is provided in communication with the pressure chamber 26, the valve (8) which is opened and closed by the drive unit 9 in the outlet port 7 is provided by the inlet port The drive unit 9 is connected to the pressure sensor 10 provided at (2) and the wire 11.
상기 필터체(13)에는 유입구(2)측에 축공(18)을 갖는 고정테(17)를 설치하여 걸림환턱(5)에 지지시키고, 축공(18)에 축(21)으로 세척구(19)를 설치하되, 후방을 고정판(25)으로 고정환턱(6)에 설치한다.The filter element 13 is provided with a fixed frame 17 having a shaft hole 18 on the inlet port 2 side to be supported by the locking ring jaw 5, and a washing hole 19 with a shaft 21 in the shaft hole 18. ) Is installed, but the rear is fixed to the fixed jaw (6) with a fixed plate (25).

도면중 미설명 부호, 27, 28은 보울트이다.In the drawings, reference numerals 27 and 28 are bolts.
이와같이 구성된 본 고안은 도면의 제1도에 나타낸 바와같이 밸브(8)가 폐쇄된 상태에서 여과코져하는 오염된 액상형태물질을 유입구(2)로 압송하게 되면 액상형태물질의 일부는 필터체(13)의 내벽과 흡입노즐(22) 사이의 간극을 통해 흡입노즐(22)내로 진입하여 연통관(20)을 통해 분사노즐(23)의 분사공(24)으로 유출되어 압력실(26)내로 충전케 되는데, 압력실(26)에 액상형태물질이 충전된 다음에는 더이상의 유출이 불가능하게 되므로 이때부터는 필터체(13) 내부에 압력이 상승하게 되어 액상형태물질에 혼재된 불순물은 필터체(13)에 걸러지고 여과된 액사형태물질은 유도로(4)를 통해 유출구(3)로 수거되어 산업분야에 재활용케 되는 것으로, 계속적인 여과를 수행하게 되면 필터체(13)의 내벽에 다량의 불순물이 집적되므로서 필터체(13)의 기공이 막히게 되어 액상형태물질이 필터체(13)를 통과하기가 어려워지게 될 것이고 이에 따라 유입구(2)측의 압력이 설정치 이상으로 상승하게 될 것인바, 이때 압력감지센서(10)가 유입구(2)측의 고압력을 감지하여 구동부(9)를 작동시키게 되므로 이에 연동되는 밸브(8)가 도면의 제3도에 나타낸 바와같이 설정된 시간만큼 개방되는데 밸브(8)가 개방된 상태에서는 압력실(26)내의 압력이 급격히 하강하게 되므로 유입구(2)측으로 압송된 액상형태물질이 도면 제2도의 (a)에 나타낸 바와같이 필터체(13)의 내벽과 흡입노즐(22) 선단 사이의 간극을 통해 진입하여 연통관(20)을 경유하게 되면서 도면 제2도의 (b)에 나타낸 바와같이 분사노즐(23)의 분사공(24)으로 분사되므로서 세척구(19)가 분사압력에 의해 회전하므로서 흡입노즐(22)이 필터체(13) 내벽에 집적된 불순물을 긁어서 탈리시킴과 동시에 흡입노즐(22)를 통해 액상형태물질과 함께 배출구(7)로 배출되도록 하여 별도로 수거 처리케 되므로서 환경오면을 방지함과 동시에 필터체(13)의 여과효율을 최상의 상태로 유지할 수 있도록 하여 필터체(13)의 사용수명 또한 장기화하게 되며, 필터체(13)의 청소작업 시간을 단축하게 되는 것이다.When the contaminated liquid form material is filtered to the inlet port 2 while the valve 8 is closed, as shown in FIG. 1 of the drawing, a part of the liquid form material is filtered. Into the suction nozzle 22 through the gap between the inner wall and the suction nozzle 22 and flows into the injection hole 24 of the injection nozzle 23 through the communication tube 20 to be filled into the pressure chamber 26. However, after the liquid form material is filled in the pressure chamber 26, no further outflow is possible. From this time, the pressure is increased inside the filter element 13, and the impurities mixed in the liquid form material are filtered. The filtered and filtered liquid form material is collected into the outlet 3 through the induction furnace 4 and recycled to the industrial field. When continuous filtration is carried out, a large amount of impurities are formed on the inner wall of the filter body 13. The pores of the filter body 13 are blocked by being integrated. It will be difficult for the liquid form material to pass through the filter body 13, and thus the pressure at the inlet port 2 will rise above the set value, where the pressure sensor 10 is at the inlet port 2 side. Since the driving unit 9 is operated by detecting the high pressure of the valve 9, the valve 8 linked thereto is opened for a predetermined time as shown in FIG. 3. However, in the open state of the valve 8, the valve 8 is opened. As the pressure drops sharply, the liquid-form material pushed toward the inlet 2 enters through the gap between the inner wall of the filter body 13 and the tip of the suction nozzle 22 as shown in FIG. The suction nozzle 22 is rotated by the injection pressure while being sprayed by the injection pressure through the injection hole 24 of the injection nozzle 23 as shown in (b) of FIG. Scratches and removes impurities accumulated on the inner wall of the filter element 13 At the same time, the suction nozzle 22 is discharged to the discharge port 7 together with the liquid form material to be separately collected, thereby preventing environmental pollution and maintaining the filtration efficiency of the filter body 13 at the best state. In this way, the service life of the filter element 13 is also prolonged, and the cleaning operation time of the filter element 13 is shortened.
여기에서, 밸브(8)의 개폐를 제어하는 구동부(9)는 통상 밸브캐폐에 사용되는 콘트롤러를 사용하되 개폐시간의 조절을 위하여 타이머가 부설된 것을 사용하는 것이 바람직할 것이나, 정전이나 기타 전기적 문제에 의해 구동부(9) 및 압력감지센서(10)의 작동이 불가능하게 될 경우를 대비하여 밸브(8)를 수동으로도 개폐할 수 있도록 함이 요구된다.Here, the drive unit 9 for controlling the opening and closing of the valve (8), but it is preferable to use a controller that is normally used for the valve closing, but to use a timer attached to adjust the opening and closing time, power failure or other electrical problems It is required to be able to open and close the valve (8) manually in case the operation of the drive unit 9 and the pressure sensor 10 is impossible by.
한편, 필터체(13)는 여과효율을 높이기 위하여 밀도가 조밀한 것으로 사용할 수도 있겠으나, 이 경우 투과율이 낮아져 단위시간당 여과량이 비례하여 줄어들게 될 것이므로, 밀도가 성글은 필터(14)를 내측에 위치시키고 점진적으로 밀도가 조밀한 순서를 갖는 필터(14')(14)를 외측으로 다층 중첩시키게 되면 여과효율과 투과율을 동시에 만족시킬 수 있게 되는 반면 내압력성 및 내구성이 떨어지게 될 것인바, 이의 보강을 위하여 필터체(13)의 내·외 표면에 통공을 무수히 형성된 지지판(15)(15')을 중첩 형성함이 바람직한 것으로, 필터체(13)의 중첩구조는 여과코져하는 액상형태물질의 종류에 따라 복층 또는 다층형성할 수도 있음은 물론 다공성 세라믹 필터등의 단일체로 형성할 수도 있는 것이다.On the other hand, the filter body 13 may be used to have a dense density in order to increase the filtration efficiency, but in this case, the permeability will be lowered so that the amount of filtration per unit time will be proportionally reduced, so that the densely located filter 14 is located inside. In this case, if the filters 14 'and 14 having a progressively dense order are stacked on the outside, the filter efficiency and permeability can be simultaneously satisfied, while the pressure resistance and durability will be reduced. For this reason, it is preferable to overlap the supporting plates 15 and 15 'formed with an infinite number of through holes on the inner and outer surfaces of the filter element 13, and the overlapping structure of the filter element 13 is a kind of liquid form material to be filtered. According to the present invention, a multilayer or multilayer may be formed, as well as a single body such as a porous ceramic filter.
그러므로, 여과코져하는 액상형태물질의 종류에 따라 상기와 같은 여러종류의 필터체(13)를 구비할 경우 종류별로 동일수량의 하우징(1)을 구비해야 할 것이나, 설치면적이나 경제적인 측면을 고려하여 필터체(13)을 고정판(25)으로 고정토록함과 동시에 밀폐판(12)으로 압력실(26)을 폐쇄토록 하므로서 1개의 하우징(1)에 필터체(13)를 종류별로 교체하여 사용할 수 있도록 하였는 바, 보울트(28)를 해체하여 밀폐판(12)를 분리한 다음 보울트(27)를 해체하여 고정판(25)을 분리시키게 되면 세척구(19)와 필터체(13)를 압력실(26)측으로 분리시킬 수있게 되므로, 이와같은 작업을 역순으로 수행함으로서 다른 종류의 필터체(13)로 쉽게 교체할 수 있게 되어 1개의 하우징(1)으로 다양한 종류의 액상형태물질을 여과할 수 있으므로 설치공간을 최소화함은 물론 경제적인 잇점 또한 갖게 되는 것이다.Therefore, in the case of providing the various types of filter bodies 13 as described above according to the type of liquid form material to be filtered, the same quantity of housings 1 should be provided for each type, but considering the installation area and economic aspects. The filter body 13 to be fixed to the fixing plate 25 and the pressure chamber 26 to be closed by the sealing plate 12 to replace the filter body 13 for each type of housing 1. When the bolt 28 is dismantled to separate the sealing plate 12 and then the bolt 27 is disassembled to separate the fixing plate 25, the washing port 19 and the filter body 13 are separated from the pressure chamber. Since it can be separated to the (26) side, it is possible to easily replace with another type of filter body 13 by performing the same operation in the reverse order, so that various types of liquid form materials can be filtered through one housing (1). Therefore, the installation space is minimized and economical Points will also be given.
이상에서와 같이 본 고안은 1개의 하우징을 이용하여 여러종류의 액상형태물질을 여과할 수 있음은 물론, 여과도중 불순물이 필터체에 집적되어 필터체를 청소해야 할 경우 필터체를 분리하지 않고도 자동으로 불순물을 제거할 수 있게 되는 등의 매우 실용적인 효과를 제공케 되는 것이다.As described above, the present invention can filter various types of liquid form materials using one housing, and also, if impurities are accumulated in the filter body and need to clean the filter body, This will provide a very practical effect, such as being able to remove impurities.
