Abstract

The present invention relates to a method and apparatus for removing water from a fibrous web. The invention is intended especially for applications to be used in a twin wire former of a paper or a board machine. A problem earlier experienced in foudrinier machines has been fiber flocking in the web surface, which results from a Iong and tranquil period of flowing, during which period fibers have enough time to stick to one another and form flocks that deteriorate the paper quality. This problem has been solved by arranging rows of dewatering pressure elements (24, 32, 33) as part of the covers (25, 34, 33) of both upper and lower dewateri::g units (20, 30) so as to match or be aligned at least partly, whereby they generate an intensive turbulence field into the web surface to break the flocks that have already been formed.

Claims (8)

수평 탈수부에서 이미 물이 제거된 웨브를 2개의 와이어 사이에서 압축시켜 양 와이어를 통하여 물이 제거되도록 하는 웨브의 탈수 방법에 있어서, 탈수 유니트들의 가압 부재의 배열에 의하여 웨브에 강한 난류가 발생하고, 상기 유니트들은 웨브의 반대편에 배치되며, 상기 난류는 웨브면과 대체로 동일한 방향의 유도 및 웨브면과 대체로 수직인 방향의 유동의 왕복 진동으로 이루어지고 이 난류에 의하여 웨브 표면에서 섬유가 뭉친 것이 분산되는 것을 특징으로 하는 방법.In a method of dewatering a web in which water, which has already been removed from the horizontal dewatering part, is compressed between two wires so that water is removed through both wires, strong turbulence occurs in the web by the arrangement of the pressure members of the dewatering units. The units are arranged on opposite sides of the web, the turbulence consisting of induction in the same direction as the web surface and reciprocating vibrations of the flow in a direction generally perpendicular to the web surface, whereby the turbulence disperses the agglomeration of fibers on the web surface. Characterized in that the method. 제 1 항에 있어서, 난류의 강도 및 난류 성분의 분포는 한 탈수 유니트의 다른 탈수 유니트에 대한 정렬상태를 변위시켜 조절되는 것을 특징으로 하는 방법.The method of claim 1 wherein the intensity of the turbulence and the distribution of turbulent components are adjusted by displacing the alignment of one dehydration unit with respect to the other dehydration unit. 웨브의 상하에 탈수 유니트(20,30)가 배치되어 웨브로부터 물을 제거하는 이른바 이중 와이어 성형기 형식의 탈수 장치에 있어서, 탈수 유니트(20,30)의 대체로 평면부 또는 덮개(25,34,35)가 웨브를 수용하는 한쌍의 와이어(4,10)의 대향면 상에서 간격을 두고 있는 가압 부재(24,32,33)로 이루어지고, 상기 가압 부재는 반대편 열의 가압 부재와 적어도 부분적으로 정렬되는 것을 특징으로 하는 장치.In the dehydration device of the so-called double wire molding machine in which dewatering units (20,30) are disposed above and below the web to remove water from the web, generally the flat portion or the cover (25, 34, 35) of the dewatering unit (20,30). ) Consists of a pressing member (24, 32, 33) spaced on opposite sides of the pair of wires (4, 10) for receiving the web, said pressing member being at least partially aligned with the pressing member in the opposite row. Characterized in that the device. 제 3 항에 있어서, 적어도 하나의 탈수 유니트(30)의 덮개(34,35)가 적어도 2부분으로 이루어지는 것을 특징으로 하는 장치.4. Device according to claim 3, characterized in that the cover (34,35) of the at least one dewatering unit (30) consists of at least two parts. 제 3 항 또는 제 4 항에 있어서, 탈수 유니트(20,30)의 덮개(24,34,35)가 웨브에 대하여 종방향으로 조절될 수 있는 것을 특징으로 하는 장치.5. Device according to claim 3 or 4, characterized in that the cover (24, 34, 35) of the dewatering unit (20, 30) can be adjusted longitudinally relative to the web. 제 3 항 또는 제 4 항에 있어서, 한 탈수 유니트(30)의 덮개(34)의 최종 가압 부재와 동일 탈수 유니트의 다음 덮개(35)의 최초 가압 부재 사이의 거리는 반대편 탈수 유니트의 덮개(25)의 가압 부재들(24) 사이의 거리와 다르거나 그 수 배가 되는 것을 특징으로 하는 장치.The distance between the last pressing member of the lid 34 of one dewatering unit 30 and the first pressing member of the next lid 35 of the same dewatering unit is the lid 25 of the opposite dewatering unit. And a multiple of or different from the distance between the pressing members (24) of. 제 3 항 또는 제 4 항에 있어서, 한 탈수 유니트(30)의 덮개(34)의 최종 가압 부재와 동일 탈수 유니트의 다음 덮개(35)의 최초 가압 부재 사이의 거리는 반대편 탈수 유니트의 덮개(25)의 가압 부재들(24) 사이의 거리와 같거나 그 수 배가 되는 것을 특징으로 하는 장치.The distance between the last pressing member of the lid 34 of one dewatering unit 30 and the first pressing member of the next lid 35 of the same dewatering unit is the lid 25 of the opposite dewatering unit. The device equal to or several times the distance between the pressing members (24). 제 3 항 또는 제 4 항에 있어서, 적어도 한 탈수 유니트(30)의 덮개(34,35) 사이의 거리가 조절 가능한 것을 특징으로 하는 장치.5. Device according to claim 3 or 4, characterized in that the distance between the covers (34, 35) of at least one dehydration unit (30) is adjustable. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
