Abstract

Foreliggende oppfinnelse vedrorer en silinnretning i tilknytning til fjerning av væske gjennom et masseleie, fortrinnsvis i forbindelse med uttak av kokevæske i en kontinuerlig koker (1) for produk- sjon av kjemisk masse, hvilken silinnretning (2) fortrinnsvis er rektangulær og omfatter et antall silstenger (3) anordnet parallelt, hvilke har blitt festet til minst to stangelcmcnter (4,5) som er plas- sert på tvers i forhold til lengderetningen av stangsilcne. Siungclcmcntcne (4,5) er laget av me- tall, fortrinnsvis rustfntt stål, og har en fasthets- verdi RP 02 ved 100nC som overstiger 200 MPa, fortrinnsvis 300 MPa, og mer foretrukket 350 MPa, og bredden av stangelementct (4) er mindre enn 800 mm, fortrinnsvis 650 mm, og mer foretrukket 550 mm, slik at silinnrctningen blir selvbærende.
