Abstract
The utility model relates to a fourdrinier part without vacuum couches, which belongs to the field of papermaking equipment, and composes a fourdrinier wire, wherein a flow box, a breast roll, a forming plate, a vacuum box, a wire driving roll, a stretching device and a correcting device are arranged in sequence along the surface of the fourdrinier wire; a wiper blade is arranged between the forming plate and the vacuum box and is fixed on a support saddle; and a guide roll is arranged between the vacuum box and the flow box. Under the premise of ensuring the dehydration of slurry and the forming quality of paper sheets, the utility model simplifies the dehydration structure of the fourdrinier part of the paper machine, and reduces the equipment investment and the manufacturing cost.
Description
Technical field
The utility model belongs to the paper making equipment field, is specifically related to a kind of fourdrinier part or folder wet end of paper machine.
Background technology
Wet end is the major part that paper machine is formed, and its main effect is to slough most moisture in the online slurry, forms the wet web of full width uniformity, and its dewatering type is to filter, aspirate dehydration.The water yield that general wet end is sloughed accounts for more than 95% of online de-watering of slurries amount.The wet end of conventional fourdrinier by breast roll, forming board, table roll, chopping board, gravity dehydration case, wet vacuum tank, vacuum tank, suction couch roll, drive net roller, wite roll, tensioning apparatus, means for correcting etc. and net is supported form forming table.Dewatering elements under the wire side is by water separation capability order arrangement from weak to strong.Dehydration shaping principle is as follows: slurry flows on the wire side with certain speed from head box uniformly, because effects such as gravity, suction force and forming table vibrations, most of moisture is filtered by papermaking wire-cloth drain.The dehydration forming process is as follows: slurry flows out through breast roll and forming board, table roll etc. from head box and dewaters more lenitively; Dewater in a large number through dewatering plate and wet vacuum tank, this moment, the l Water Paper page or leaf was shaped substantially again, and the resistance that dewaters strengthens, and transferred to press section through vacuum tank and the further dehydration of suction couch roll after suction moves roller more at last.The shortcoming of this wire-cloths is that dewatering device is more lengthy and tedious, equipment input and operating cost height.
The utility model content
The technical problems to be solved in the utility model is the cost height of existing wire-cloths complex structure, equipment input and operation, a kind of fourdrinier part that does not have suction couch roll is provided, under the prerequisite of dehydrating amount that guarantees slurry and sheet forming quality, can simplify the wire-cloths dehydrated structure, reduction equipment drops into and production cost.
The technical solution of the utility model realizes in the following manner:
A kind of fourdrinier part that does not have suction couch roll, comprise net, be provided with head box, breast roll, forming board, vacuum tank successively, drive net roller, tensioning apparatus and means for correcting along net surface, be provided with Wiper blade between forming board and the vacuum tank, Wiper blade is fixed on the bearing, is provided with deflector roll between vacuum tank and the head box.
Described Wiper blade is the Wiper blade of ceramic material.
Described bearing is the stainless steel bearing.
Described deflector roll is coated with anticorrosive coat.
Compared with prior art, the utlity model has following beneficial effect:
1. simplified structure reduction equipment drops into: the utility model utilizes the table roll, gravity dehydration case of Wiper blade substitute structure complexity etc., utilizes deflector roll to replace suction couch roll, and the wet end structure is simplified greatly.By the adjustment of Wiper blade quantity, distance, angle being controlled the dehydration intensity and the dewatering speed of wet end.Under the Wiper blade effect, slurry evenly disperses on the net, make the full width page quantitatively, thickness, evenness unanimity.Both guarantee the quality of wet end page, reduced the equipment input again significantly.
2. reduced operating cost: the bearing of table roll, ornamenting roller, encapsulate layer etc. are damageable zone in the traditional scheme, adopt ceramic Wiper blade in the utility model after maintenance cost reduce significantly; Suction couch roll in the traditional scheme, ornamenting roller all need add transmission, the utility model had both been saved power consumption after changing common deflector roll into, have saved the maintenance cost of vacuum equipment, drive apparatus again.Because the utility model has been simplified dehydrated structure, has cancelled the vacuum dehydration of suction couch roll, so reduced the wearing and tearing of dewatering elements to the papermaking net, the net life-span prolongs at double, makes the consumption of net and maintenance cost reduce significantly.
3. convenient operating maintenance: because the utility model has been simplified the wet end dehydrated structure, reduced maintenance workload,, improved production efficiency so shortened maintenance downtime greatly.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, the utility model, comprise net 8, surface along net 8 is provided with head box 1, breast roll 2, forming board 3, vacuum tank 9 successively, drives net roller 11, tensioning apparatus 7 and means for correcting 6, be provided with Wiper blade 4 between forming board 3 and the vacuum tank 9, Wiper blade 4 is fixed on the bearing 5, is provided with deflector roll 10 between vacuum tank 9 and the head box 1.
Described Wiper blade 4 is the Wiper blade of ceramic material or the preparation of other resistant materials.
Described bearing 5 is adjustable slot steel, plate, perhaps circular, rectangular tube bearing, and material is stainless steel or other resistant materials, can guarantee that Wiper blade has certain rigidity and intensity.
Described deflector roll 10 is coated with anticorrosive coat.Described anticorrosive coat can be encapsulate, copper facing, chromium plating or the like outside deflector roll 10.
The utility model slurry flow process is as follows: head box-forming board-Wiper blade-vacuum tank-deflector roll-move roller through the vacuum suction to transfer to press section.After slurry flows out from head box 1,, through Wiper blade 4 dehydrations, further dewater through vacuum tank 9 more then earlier through forming board 3, can make web dryness reach 〉=18%.Can guarantee that fully the l Water Paper page or leaf is to the press section transmission.
In the utility model, slurry sprays from head box 1 to be fallen on the net 8 along with net 8 moves backward, earlier through forming board 3, Wiper blade 4 dehydrations, it is qualified to form evenness then after vacuum tank 9 further dewaters, the page of mass dryness fraction 〉=18%, at last through deflector roll 10 after inhale and to move roller and transfer to press section and further dewater.Net separates with page after drive the net roller and drive and to return under forming table, walks around to go round and begin again behind the breast roll 2 through tensioning apparatus 7, means for correcting 6 and carries out the next round circulation.
