This type of compressed filtration plate is a rubber plate coated on both sides of the substrate and having a filtration groove on the surface thereof, and after normal filtration in a state where all the filter plates are overlapped and adhered, a fluid (between the substrate and the rubber plate) The filter medium is press-fitted to expand the rubber plate into the filtration chamber, whereby the filter medium after filtration can be pressed again.

그런데, 제5도에 도시된 바와 같이 종래기판(1) 및 양 고무판(2)의 원액공급구(3)가 되는 각 관통공(4), (5)은, 다함께 그 직경이 동일하게 형성되어 있고, 각 고무판(2)의 주연부(周緣部)에 링모양의 압입구(6)가 대어지고, 이를 볼트·너트(7)로 체착하고 있다. 따라서 원액공급구(3)의 주연부에 있어서의 접합부(8), (9)는 2개소가 있는 것이 되고 따라서 2개소로부터 압입되는 유체가 누출될 염려가 있었다. 또 기판(1)의 상기한 접합부분은, 고무판(2)과 긴밀하게 접착되도록 평활면으로 형성시킬 필요가 있었다.However, as shown in FIG. 5, each of the through holes 4 and 5 serving as the stock solution supply ports 3 of the conventional substrate 1 and the rubber plates 2 are formed with the same diameter. The ring-shaped press-fitting inlet 6 is placed on the periphery of each rubber plate 2, and is fastened with the bolt nut 7. Therefore, the joints 8 and 9 at the periphery of the stock solution supply port 3 have two places, so that the fluid pressurized from the two places may leak. Moreover, it was necessary to form the said junction part of the board | substrate 1 on the smooth surface so that it may adhere closely to the rubber plate 2.

본 발명의 목적은, 상기한 접합부를 1개소로 함으로써, 압압유체가 누출되는 위험성을 종래에 비교하여 적어도 반감시키는 데 있다. 본 발명의 실시예를 도면에 의하여 상세히 설명하면 다음과 같다.An object of the present invention is to at least halve the risk of the pressurized fluid leaking compared to the prior art by using one of the above-mentioned joints. An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

세1도 내지 제4도에 있어서, 압착여과판(11)은, 종래와 길이 기판(12)과 고무판(13)으로 구성되어 있고 중앙에는 원액공급구(14)를 우상귀 및 좌하귀에 여과액출구(15) 및 그 출구(15)와 함께 내측에 여과액 수집구(29)를, 우하귀에 압착용 유체입구(16)가 각각 뚫려져 있다. 여과액출구(15)와 여과액서 수집구(29)는 여과액통로(30)로 연결되어 있다(제1도 참조).In FIGS. 1 to 4, the pressure filtration plate 11 is conventionally composed of a length substrate 12 and a rubber plate 13, and a stock solution supply port 14 is formed at the center of the filtrate outlet at the upper right and lower left. 15 and the outlet 15, the filtrate collection port 29 is formed inside, and the pressurized fluid inlet 16 is drilled in the lower right, respectively. The filtrate outlet 15 and the filtrate collection port 29 are connected to the filtrate passage 30 (see FIG. 1).

양고무판(13)의 상단에는, 기판(12)의 상단에 걸쳐지는 내측 돌출연부(17)가 형성되어 있고, 그 외면에는 소정의 간격을 두고 볼트의 머리부분 또는 너트가 수용되는 장방형 요입부(18), (19)형성되어 있다.On the upper end of both rubber plates 13, an inner protruding edge 17 is formed which extends over the upper end of the substrate 12, and on its outer surface a rectangular concave part which accommodates the head or nut of the bolt at a predetermined interval ( 18), (19).

요입부(18), (19)있는 개소에서, 대향하는 돌출연부(17) 사이에 스페이서(20)가 개재되어, 양돌출연부(17) 끼리가 볼트·너트(21)에 의하여 연결되어 있다(제1도 및 제2도 참조).At the location with the recesses 18 and 19, a spacer 20 is interposed between the opposing protruding edges 17, and the both protruding edges 17 are connected by the bolt nut 21 ( See FIGS. 1 and 2).

기판(12)의 중앙에는, 관통공(22)이 뚫려 있고, 양고무판(13)에는, 공동으로 기판(12)의 관통공(22)의 내주면을 피복하며 또 원액공급구(23)를 형성하는 환상돌출불(24)가 형성되어 있다. 양 환상돌출부(24)의 외면에는, 소정의 간격을 두고 볼트의 머리 또는 너트를 수용하는 원형입부(25)가 형성되어 있고, 그 내부에는, 고무의 신장을 억제하기 위하여 횡단면이 U자형으로 된 환상철심(環狀芯金)(26)이 매몰되고, 양 환상돌출부(24)가 볼트·너트(27)에 의하여 긴밀하게 체결되어 있다. 이와 같이 체결된 양환상돌출부(24)에는, 횡단면이 U자형으로 되고 또 두께가 얇은 환상의 고무커버(28)가 피복되어 있다(제3도 참조).A through hole 22 is formed in the center of the substrate 12, and both rubber plates 13 collectively cover the inner circumferential surface of the through hole 22 of the substrate 12 and form a feed solution supply port 23. An annular projection 24 is formed. On the outer surface of both annular projections 24, a circular mouth 25 is formed which receives the head or nut of the bolt at predetermined intervals, and inside thereof, the cross section is U-shaped in order to suppress elongation of the rubber. The annular iron core 26 is buried, and both annular projections 24 are tightly fastened by the bolt nut 27. The ring-shaped protrusions 24 fastened in this way are covered with an annular rubber cover 28 having a U-shaped cross section and a thin thickness (see FIG. 3).

여과액수집구(29)는, 기판(12) 및 양고무판(13)에 각각 뚫려진 관통공(31)(32)에 의하여 형성되어 있다.The filtrate collecting ports 29 are formed by through holes 31 and 32 drilled through the substrate 12 and the rubber plate 13, respectively.

양고무판(13)의 주연부에는, 원형 압압구(33), (34)가 대어져 있고, 볼트(37)로 체결되어 있다. 이 때문에, 한쪽 압압구(33)에는,데 소정의 간격을 두고 볼트의 머리가 수용되는 요입부(凹所)(35)가 형성되고, 다른쪽 압압구(34)에는 요입부(35)대응하는 위치에 나사구멍(36)이 뚫려지고, 기판(12) 및 양고무판(13)에 각각 나사 삽입공(42), (43)이 뚫려져 있다. 양 압압구 (33), (34)의 중앙에는, 여과액 수집구(29)와 연통되는 관통공(38)이 뚫려지고, 여기에 연통되도록 양 압압구(33), (34)의 주벽에서 여과액통로(39)가 방사상으로 뚫려져 있다. 압압구(33), (34)의 내면에는, 관통공(38)의 주연에 따라서 환상홈(40)이 형성되어 있고, 이에 양 고무판(13)의 관통공(32)의 주연에 형성된 환상돌출부(41)가 감합되어 있다(제4도 참조).Circular pressing holes 33 and 34 are attached to the periphery of both rubber plates 13, and are fastened with bolts 37. For this reason, the one indentation part 33 is provided with the recessed part 35 in which the head of a bolt is accommodated at the predetermined space | interval, and the other indentation part 34 respond | corresponds to the recessed part 35. The screw hole 36 is drilled at the position where the screw hole 36 is positioned, and the screw insertion holes 42 and 43 are drilled in the substrate 12 and the rubber plate 13, respectively. In the center of the positive pressure ports 33 and 34, a through hole 38 communicating with the filtrate collection port 29 is drilled, and at the circumferential wall of the positive pressure ports 33 and 34 so as to communicate therewith. The filtrate passage 39 is radially drilled. Annular grooves 40 are formed in the inner surfaces of the pressing holes 33 and 34 along the periphery of the through holes 38, and the annular protrusions formed at the periphery of the through holes 32 of both rubber plates 13 are formed. (41) is fitted (see FIG. 4).

압압구(33), (34)의 표면에는, 관통공(38)에 여과포가 들어가는 것을 막기 위하여, 망(45)이 씌워져 있다. 그리고 원액공급구(14)는 반드시 여과판(11)의 중앙에 있을 필요는 없고, 여과판(11)의 중앙과 그 여과판(11)의 하반부의 중간을 연결하는 선상의 어느 곳에도 있으면 좋다.In order to prevent the filter cloth from entering the through hole 38, the mesh 45 is covered on the surfaces of the pressing holes 33 and 34. The stock solution supply port 14 does not necessarily need to be in the center of the filter plate 11, but may be located anywhere along the line connecting the middle of the filter plate 11 and the lower half of the filter plate 11.

본 발명에 의한 압착여과판은, 기판(12)과 기판(12)의 양면에 피복되고 또한 표면에 여과홈을 가진 고무판(13)으로 되고, 기판(12)의 소정 위치에 관통공(22)이 뚫려지며, 양고무판(13)에는, 공동으로 기판(12)의 관통공(22)의 내주면을 피복하고 또 원액공급구(23)를 형성하는 환상돌출부(24)가 형성되며, 양환상돌출부(24)가 볼트·너트(27)등으로 긴밀하게 체결되어 있으므로, 제3도에서 명백한 바와 같이, 원액 공급구(3)의 주연부에 있어서의 접합부(44)는 1개소만으로 될 뿐 아니라, 기판(12)의 관통공(22)의 내주면이 피복되어 있다. 따라서 전체여과판(11)을 중합(重合)시킨 여과작업에 있어서, 기판(12)과 고무판(13)과의 격리부(46)에 유체를 압입한 때 제5도의 종래예와 같이, 2개소의 접합부(8), (9)가 있는 것에 비하여 접합부로부터 유체가 누출할 염려는 확실히 반감이하가 된다. 또 본 발명에 의하면, 접합부(44)는 기판(12)의 표면 이외의 개소에 있기 때문에, 기판(12) 자체를 접합시키기 위하여, 특히 부분적으로 평활(平滑)하게 손질할 필요가 없으며, 접합부(44)는 고무끼리의 접합이므로 충분하게 기밀(氣密)을 유지된다.The compressed filtration plate according to the present invention is a rubber plate 13 coated on both surfaces of the substrate 12 and the substrate 12 and having a filtration groove on the surface thereof, and the through hole 22 is formed at a predetermined position of the substrate 12. The annular projections 24 are formed in the rubber plate 13 to cover the inner circumferential surface of the through hole 22 of the substrate 12 and form the stock solution supply port 23. Since 24 is tightly fastened with a bolt nut 27 or the like, as shown in FIG. 3, the joining portion 44 at the periphery of the stock solution supply port 3 is not only one but also the substrate ( The inner circumferential surface of the through hole 22 in 12 is covered. Therefore, in the filtration operation in which the whole filtration plate 11 is polymerized, when the fluid is press-fitted into the separator 46 between the substrate 12 and the rubber plate 13, as in the conventional example of FIG. Compared to the presence of the joints 8 and 9, the risk of leakage of fluid from the joint is certainly less than half. In addition, according to the present invention, since the bonding portion 44 is located at a place other than the surface of the substrate 12, in order to bond the substrate 12 itself, there is no need to particularly smoothly trim the bonded portion ( 44 is sufficiently bonded because rubber is bonded together.
