Abstract
The utility model relates to a high efficiency cylinder type former, belonging to the field of paper technology. The high efficiency cylinder type former can reach the purpose of evenly distributing pulp without using any evener roll. Paper stock is not flocculated and fibers are well interweaved. The utility model is characterized in that an upper net pulp channel is provided with a plurality of reverse turns in proximity to rectangle, so the upper net pulp channel is provided with a bow-shaped pulp channel in the cast shadow which is vertical to a pulp flowing curve face. Therefore, power consumption can be reduced.
Description
The utility model belongs to pulp technology for making paper, particularly relates to cylinder mould machine.
The wet end of cylinder mould machine is the formation part of page, the paper stock of online contacts with the cylinder of rotation with the concentration of regulation, filtering means dehydration effect through cylinder, fiber just forms the l Water Paper layer on wire side, this l Water Paper layer meets with cylinder that rotates and the woollen blanket that is coating couch roll, and through the extruding of couch roll, ply of paper just is attached on the woollen blanket and is taken away by woollen blanket.By technological requirement: being flowing in " macroscopic view " and seeing it should is steadily uniformly of slurry, require to have the microturbulence of fine micro cyclone simultaneously again, to promote interweaving of fiber, the pulling force in length and breadth that reduces paper is poor.The domestic frost boiling formula net groove that drops down of commonly opening cooperates doctor-roll now, and the pressure that has also proposed multiple air-cushion type or flowing full formula simultaneously is for the slurry scheme, but always depend on doctor-roll and make the cloth slurry evenly, fiber interweaving causes the greater loss of starching flow head, and the difficulty of maintenance and cleaning.
The purpose of this utility model provides a kind of efficient cylinder former that does not need doctor-roll also can form high-quality l Water Paper layer.
The new purpose of this practicality is achieved in that
A kind of efficient cylinder former, include into slurry distributor, online slurry road, upper and lower labial lamina, cylinder, couch roll, woollen blanket etc., it is characterized in that described online oar road has several inflection that approach the right angle, it is contained in the perspective view perpendicular to slurry stream curved surface have " bow " font slurry road that width changes.
The utility model is because its online slurry road is " bow " font, have several inflection that approach the right angle, slurry is flowed through behind this online slurry road, be subjected to the effect of frost boiling, it is poly-to have overcome wadding, width variation in the online slurry road makes that the flow velocity of slurry is sometimes fast and sometimes slow again, change acting in conjunction with the flow direction of slurry, make fiber form suitable interweaving, do not need doctor-roll also can form quality l Water Paper layer preferably, thereby reduced the dynamic head loss of slurry stream, reduced energy resource consumption.
Introduce an embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
The utility model shown in Figure 1, it advances to starch distributor 1 side's of being Taper Pipe and cooperates the bundled tube multitube to advance slurry; The pressure type online slurry road 2 of flowing full comprises flash chamber 21 successively, vertical lifting is starched flaring slurry road 25, level slurry road 26, vertical lifting slurry road 27, oblique starching road 28, the vertical lifting slurry road 29 of road 22, cambered surface flash chamber 23, level slurry road 24, vertical lifting and the oblique starching road of being made up of upper and lower labial lamina 31,32 20, and " bow " font is partly promptly formed in 23,24,25,26,27,28,29,20 8 among the online slurry road 2; Top lip of slice 31 has adjusting device 31D; Cylinder 4 adopts stainless steel sheet rotary screen cage, and the spoke wheel type of casting wants light and handy, and it is more convenient to dewater; Couch roll 5 is installed on the frame by an activity swing arm 51, is disposing the counter weight 52 that can move along swing arm 51 in the swing arm 51, in order to regulate the pressure that couch roll 5 imposes on cylinder 4; Woollen blanket 6 is through the top of the starching side of cylinders 4, upwards moves to felt leading roll 61 after walking around couch roll 5, accelerates the dehydration of l Water Paper pages or leaves therebetween through suction flat box 7; At couch roll 5 and cylinder 4 contacted positions, the below is provided with plain boiled water fairlead 8; Middle part in vertical lifting dilatation slurry road 25 is connected with auxiliary agent non-returnly and adds pipe 9, and it distributes in stream slurry road through many arms with measuring pump 91 and adds paper making additive (as dispersant etc.).
As shown in Figure 1: after slurry classical prescription dimension pipe and bundled tube multitube advance to starch distributor 1, on through-flow, distributed comparatively evenly, enter flash chamber 21, speed slows down, cambered surface along with runner, the flow direction also changes, and vertical lifting enters slurry road 22, and flow velocity is fast a little again, through entering short convergent level slurry road 24 behind the cambered surface flash chamber 23 again, the flow direction changes 90 ° again, enters the flaring slurry road 25 of vertical lifting, here mixes with the paper making additives that add pipe 9 addings from auxiliary agent, subsequently again through horizontal convergent slurry road 26, vertical lifting slurry road 27, oblique starching road 28, vertical lifting slurry road 29 enters by last, aulaeum 31, the 32 oblique starching roads of forming 20.Adjust the width that top lip of slice 31 can change the outlet in oblique starching road 20, and then debugging mode is sprayed onto online slurry speed of cylinder 4 or the like.In sum, slurry is advancing to starch distributor 1, online slurry road 2, upper and lower labial lamina 31,32 to the wire side of cylinder 4 from square Taper Pipe and bundled tube multitube, through multitubular bundles its amount of through-flow is evenly distributed, again through the inflection of repeatedly dilatation, convergent and the flow direction, and be that the break-in of slurry rheology speed is taken place at same position sometimes, it is poly-just to make that slurry is difficult for wadding, and the stream slurry is evenly, and fiber can have preferably and interweave, and can form high-quality l Water Paper page or leaf.
Claims (3)
1, a kind of efficient cylinder former, include into slurry distributor, online slurry road, upper and lower labial lamina, cylinder, couch roll, woollen blanket etc., it is characterized in that described online oar road has several inflection that approach the right angle, it is contained in the perspective view perpendicular to slurry stream curved surface have " bow " font slurry road that width changes.
2, efficient cylinder former according to claim 1 is characterized in that described " bow " font slurry road comprises flash chamber (21) successively, vertical lifting is starched flaring slurry road (25), level slurry road (26), vertical lifting slurry road (27), oblique starching road (28), the vertical lifting slurry road (29) of road (22), cambered surface flash chamber (23), level slurry road (24), vertical lifting and the oblique starching road of being made up of upper and lower labial lamina (31), (32) (20).
