Description

Fiber fluid bolter screen cylinder

Technical field

The application belongs to papermaking separation technology field, more particularly to a kind of fiber fluid bolter screen cylinder.

Background technology

Coating screen cylinder has outer-flowing type coating screen cylinder and in-flow coating screen cylinder.

Outer-flowing type pressurized screen is used to carry out slurry the screening before coarse sizing, net screening and paper machine.The form of screen cylinder is divided again For pass and seam type, pass is divided into plain edition and vertebral foramen type again, and seam type is divided into milling seam type ripple seam and rod type ripple seam, screen slot Most I is to 0.05mm.Rotor is divided into three kinds of forms, i.e. sieve-type before roughing type rotor, selected type rotor and net by different purposes Rotor.Roughing uses closed rotor, avoids debris from winding；Selected type uses fin open-type rotor, to mitigate to screen cylinder Impact, sieve-type uses more rotor rotors before reducing power consumption net, to reduce pulp pulse.The equipment is different according to its purposes, Used mechanism form is also different thus with strong points, and screening efficiency is high, and power consumption is low.

In-flow pressurized screen (rotor is on the outside of screen cylinder) is modern relatively advanced pulp sifting equipment in the world, has sieve The characteristics of quality is high, and ability is big, and slurry flows pulse bottom is selected, is adapted as the fine screen optional equipment of wood pulp, all kinds of straw pulps, secondary stock, It is especially suitable as screening installation before the net of paper machine.Before in-flow pressurized screen is used for the refining and paper machine of pulp and paper production Net before screen.The equipment is mainly made up of housing, rotor, screen cylinder, transmission device, lifting device etc..
