The specific embodiment
Fig. 1 shows two kinds of doctor blade devices that are used for fiber web machine according to of the present invention.The wing that is included in the doctor blade device is used in particular for getting on to dewater and subtitle substance from surface to be struck off.Particularly, doctor blade device according to the present invention is applicable to and scrapes applicator roll, band and conveyer belt and surface opening roller.At fiber web machine, in paper machine and board machine, use the surface opening roller from various factor.For example in suction roll, in order vacuum (negative pressure) effect to be guided to the outside from the inboard of roller and shell to be bored a hole.These holes make the case surface opening.On the other hand, also use fluted roller, in this roller, be mainly and improve dehydrating effect and surface of shell is slotted.The suction roll that has grooved surface in addition, the housing of this suction roll is provided with hole and groove.Except groove, perhaps, can use for example blind hole as the substituting of groove.When band and conveyer belt itself have softness (soft) when surperficial, in roller, also use soft coating.In addition, for example can be slotted in the surface of band.
Usually, wing 10 comprises blade portion 11 and fixing lock part 12 (Fig. 2 a and Fig. 2 b).In two embodiment shown in Fig. 1, blade portion 11 is adapted to the surface 14 of roller 13 and touches.Wing 10 can be loaded through for example aforesaid blade drive rotaining device 15, and this blade drive rotaining device 15 comprises fixed head 16 and clamper 17.Fixed head 16 is supported on the structure of fiber web machine, loads flexible pipe 18 and is arranged between fixed head 16 and the clamper 17.Here, through wing being loaded to loading the flexible pipe pressurization.Correspondingly, can through for example with vacuum guide to load flexible pipe and with wing from surface isolation to be struck off, so that change wing.The design of this blade drive rotaining device also comprises presser blade (presser blade) 19, utilizes this presser blade can fully enlarge the support and the loading effect of clamper 17.In addition, through changing the characteristic that presser blade can change blade drive rotaining device.
The lower clamp 20 of the abnormity of clamper 17 forms the gap with presser blade 19, and the fixedly lock part of wing 10 is fitted in this gap.Guaranteed that like this wing can be held in place when carrying out simply and wing is replaced fast in blade drive rotaining device.According to the present invention, the cross section of blade portion is asymmetric, and fixedly lock part is basic symmetry, makes wing to be mounted with two kinds of different positions, and these two kinds of positions are used to provide two kinds of different functions.Because asymmetrical design, wing has two functions unexpectedly, wherein a selected function that is suitable for relevant position in each particular cases.As illustrated in the accompanying drawings equally, wing is overturn as follows: the surface as the blade portion basal surface in an application is the top surface in second application, and vice versa.Simultaneously, the side that is positioned at above-mentioned gap of wing is identical in two application.In other words, wing is to rotate around the axis that is positioned on its width.According to Fig. 2 a, this axis is parallel to the fixedly axis of symmetry of lock part 12.This axis of symmetry is by being shown in dotted line among Fig. 2 a and Fig. 2 b.
The doctor blade device that is positioned at Fig. 1 top is corresponding to first kind of function according to the present invention, and this function is squeegee (doctoring blade).In other words, the tip 21 of the blade portion 11 of wing 10 contacts surface 14 to be struck off and removes water and impurity.Advantageously, wing has the tip 22 of chamfering, in order to contact surface to be provided.Thus, avoided the formation of linear load, and wing seem to surface tilt to be struck off than known application in longer distance.The length at the tip of chamfering depends on the size of wing naturally.Usually, the length at the tip of chamfering is the 10-20% of doctor blade width.In addition, the angle at the tip of chamfering is configured to make and can comes adaptive this chamfering most advanced and sophisticated according to surface to be struck off basically.Utilize this wing, even if also can realize the good effect of striking off with less blade load.In addition, the wearing and tearing of wing reduce, and have especially reduced the risk of damaging soft-surface.
The doctor blade device of bottom that is positioned at Fig. 1 is corresponding to second kind of function according to the present invention, and this function is dewatering plate (foil blade).This dewatering plate also partly scrapes surface 14 through most advanced and sophisticated 21.Yet it is necessary between surface 14 and wing 10, forming narrow gap, and the mutual motion owing to surface 14 and wing 10 in this gap produces vacuum.This vacuum is drawn water and subtitle substance from the surface of opening wide, and helps the operation of fiber web machine like this.Known dewatering plate is thicker, and needs the clamper of the type of itself fully.No matter be which kind of is used, can both be used on a kind of blade drive rotaining device according to wing of the present invention.This is to be achieved through the flow surface 23 that is formed dewatering plate by the asymmetric jut 24 in the blade portion 11.In other words, the blade portion of wing is asymmetric, and it comprises tangible projection.Therefore blade drive rotaining device can be arranged on the normal position and use with normal mode.
The size of jut depends on the size of wing to a great extent.Usually, the effective length of flow surface is about the half the of doctor blade width.For example, in the wing of 100mm width, the effective length t of flow surface 23 is 30-60mm, more advantageously is 40-55mm.Effective length is influenced by the remainder of the design of wing also.According to the present invention, jut 24 forms mooching knife portion 11, and the angle between its outer surface 25 and 26 is 10 °-30 °, and (Fig. 2 a) more advantageously to be 15 °-20 °.Usually, along with the increase of this angle, effective length shortens.Yet this shortening can compensate through the design of wing.
The size of the wing 10 of Fig. 2 a is through considering that known blade drive rotaining device confirms.Be in the magnitude of 100mm at the width of this wing, but also can make than this wideer or narrower wing.The size of jut has the very big free degree, yet fixedly lock part must enough approach so that be engaged in the gap.Here, the minimum thickness of wing is about 2.5mm, and it is suitable for known blade drive rotaining device in this case.The part of attenuation forms neck 28, and itself and shoulder 29 all are symmetrical.Therefore, when the clamper that is made up of shoulder remained on wing in the gap, wing can be useful in the blade drive rotaining device with two kinds of different modes.The width in thin zone is about 25mm, and the thickness of wing increases by four millimeters at least afterwards here.Thicken by this, avoided harmful bending of wing.
Except this new-type wing, blade apparatus according to the present invention has new characteristic.Therefore according to the present invention, blade portion is asymmetric in cross section, and fixedly lock part is basic symmetry, make this wing can through its fixedly lock part with two kinds of opposite positions installations, in order to two kinds of different functions to be provided.In addition, in first function, wing 10 mainly has the function of striking off, and wing 10 is adapted to and surface 13 to be struck off between angle β be 6 °-16 °, more advantageously be 10 °-14 ° (Fig. 1).Therefore the blade angle (blade angle) that forms is advantageously less, can avoid wing to scrape thus and bite soft surface.Through the tip of above-mentioned chamfering, also reduced the trend of stinging of scraping.
In second function of doctor blade device, it is 1 °-10 ° that dewatering plate is adapted to the angle γ that makes between wing 10 and the surface 13 to be struck off, and more advantageously is 4 °-6 ° (Fig. 1).The gap that increases slightly forms effective vacuum effectiveness.Simultaneously, be formed for discharging the space of the water between flow surface and the surface.Advantageously, doctor blade device is installed and is become to make water after flowing through flow surface, can fall by the gravity effect.For example, itself is provided with catch tray suction roll, and water flow to the dish of squeezer and further flow to drainage equipment from fluted roller this moment.The water that separates also can strike off through another wing according to the present invention.
Wing according to the present invention advantageously is made up of plastic material, makes wing can be used in and scrapes soft roller surface, band and conveyer belt.Available plastic material has multiple, but advantageously uses HD or LD polyethylene or polypropylene.The raw material of final products have HMW, and use selected alloy addition in the mill.Particularly, maximize through making the degree of polymerization, and soak into raw material with drier oil fat material, and finally through the sintering extruding, obtain wear-resisting and hard final products, this product does not have additional stress and dimensionally stable.Utilize this type material, can make according to wing of the present invention through machining.This production method can also be made long elements.Therefore, the wing of processing is seamless.When wing comprises complete fixedly lock part, do not need independent rivet.
Fig. 2 b shows second embodiment according to wing 10 of the present invention.Except the flow surface 23 of dewatering plate, (this second embodiment's) size is consistent with the embodiment of Fig. 2 a with profile.Here, jut 24 is formed by alar part 27.The structure decrease opened wide of part raw-material amount, and this design also is applicable to through pultrusion and makes.Also can make the jut (figure does not show) of hollow through pultrusion.On the other hand, can be through a plurality of parts be combined to make wing.For example, can with the key block parts be fixed to wedge shape razor blade stock and as jut.
Fig. 4 shows the remodeling according to doctor blade device of the present invention.Here, utilize two different blades clampers 15 to show the versatility of wing 10.Intimate part uses identical Reference numeral to indicate.The left side of Fig. 4 shows and is provided with two so-called DST blade drive rotaining devices that load flexible pipe 18.Functional presser blade 19 is made up of the upper board that is fixed to clamper 17.The right side of Fig. 4 shows so-called K35 blade drive rotaining device, and this blade drive rotaining device is a rigidity, and is fixed to the doctor beam that is provided with loading element (scheming not show).Here, functional presser blade 19 is made up of the fixed head 16 of clamper.Except these, also be suitable for the blade drive rotaining device of other type, for example applicant's oneself FiberDoc blade drive rotaining device according to wing of the present invention.Blade drive rotaining device also can be provided with presser blade.In addition, blade drive rotaining device can be made up of composite or metal material.
Wing according to the present invention is general in design, makes it can adapt to nearly all known blade drive rotaining device.In addition, beat all dual-use function has covered great majority and has struck off position and demand.Through the wing that overturns simply, squeegee or dewatering plate can be provided.Under the situation of position permission, the wing that in striking off application, uses can use as dewatering plate in the back that is worn.On the other hand, the surface pressing that can apply is lower, and blade material is wear-resisting, makes that wing can keep using the long period.Utilization can reduce the quantity of different wings significantly according to blade of the present invention in fiber web machine.In addition, new-type wing need not to change main equipment or investment just can be come into operation.
