Description
The present invention relates to the especially classifying equipoment of fiber, chip or the similar particulate of lignocellulosic and/or fibre-bearing element of a kind of fibrous particles that is mainly used in different size, it comprises a metering hopper that contains classification particulate not, is located at the charging gear of a flat basically sifter in metering hopper downstream and a metering hopper, and particulate can be put on the sifter surface from the metering hopper by charging gear.In addition, the invention still further relates to a kind of being mainly used in and scatter the especially equipment of wood-fibred, wood chip or similar particulate of fibrous particles that is preferably that mixes binding agent, it has this classifying equipoment.
By German patent document 1728502 known these kind equipments.Introduced a kind of dissemination apparatus that is used to make multilayer chip net in this file, wherein, established the grid roller containing on the metering hopper base plate of classification particulate not, particulate is supplied with the rock type screening roller that is located at metering hopper downstream by their.Drop on particulate on the rock type screening roller by classification and shed on the shaker screen that is arranged in below the rock type screening roller.Here, classification is undertaken by the principle of shaking screening, thus bigger and thereby heavier particulate drop on sieve and go up zone away from rock type screening roller, and less particulate drops on the sieve of contiguous rock type screening roller.By the motion of shaker screen, the further loose particulate that drops on the sieve is dispersed on the conveyer belt that is positioned at the shaker screen below and forms fleece so they pass shaker screen.
This equipment has many shortcomings.At first especially, because the particulate of falling on the sifter is mixed with binding agent usually, therefore employed sifter is As time goes on blocked inevitably.The cleaning sifter is quite time-consuming thereby cost is high, because equipment must be out of service when cleaning.The output of classification and quality all can not be satisfactory in the equipment of the described type of preface on the other hand.
The objective of the invention is to design the equipment of the described type of a kind of preface, make it can not stop up sifter on the one hand, and can when screening quality is improved, increase output on the other hand.
Equipment from the described type of preface, by the present invention is to reach the measure that this purpose takes to be, establish a conveying device at the surface region of sifter, it have a plurality of spaced-apart can be along the segmentation of sifter apparent motion, in these segmentations each some be placed on the lip-deep particulate of sifter by charging gear and can be especially passed by surface transport along sifter.In addition, this purpose by means of a kind of be used to scatter especially mix binding agent be preferably fibrous particles especially wood-fibred, wood chip or similar particulate be mainly used in and produce molded article that is in form for the equipment of plate reaches, this equipment has by classifying equipoment of the present invention and has and is used to accept the fibroreticulate conveyer belt that is made of the particulate by sifter below being located at sifter.
Therefore, the particulate that will be placed on the sifter by the present invention is divided into some components independent of each other, and they can be through the sifter surface transport by means of pressing conveying device of the present invention.Along the sifter apparent motion, prevent the bonding of sifter by particulate on the one hand, produce a power that acts on the particulate on the other hand, this power has a component perpendicular to the sifter direction.By means of this power particulate is extruded by sifter, so correspondingly improved the production capacity of equipment.Because this portioning of particulate has reached the purpose of improving classification, because in the less component in being in a segmentation respectively particulate is fully stirred, thereby the less particulate that has prevented to be positioned at this bulk material upside cannot arrive sifter via the bigger particulate that is positioned at below them.
The bulk material that is in the segmentation forms the rotation or the rolling of particulate by moving of sieve surface, edge, thereby impels particulate to stir, and has consequently improved screening quality.
By a kind of favourable form of implementation of the present invention, at least a portion segmentation comprises that is respectively scraped materials and parts, and it abuts in the sifter surface and guides along the sifter surface to scraped finish when segment movement.Slightly abut in the lip-deep materials and parts of scraping of sifter to pressurization by means of each or to one of the small part segmentation, further strengthened the cleaning effect that causes during along the sifter apparent motion when segmentation.Meanwhile, increased the edge perpendicular to the component of sieve surface action on particulate by means of scraping materials and parts, thereby reached the purpose that improves output.
Conveying device is preferably designed as the especially scraper plate conveyer belt of circulation.The design that can make conveying device in this way not only simply but also economical.In this case this scraper plate conveyer belt be preferably designed as particulate can be at least through a subregion along passing through perpendicular to the direction on sifter surface, so particulate can pass the scraper plate conveyer belt through its charging gear by the metering hopper and is dispersed on the sifter.Make charging gear need not complicated design in this way.
By the another kind of favourable form of implementation of the present invention, the scraper plate conveyer belt especially comprises tabular pawl, and their best spacings are contained on the chain or banded supporting member of circulation equably.Here, this supporting member always can be located at the central authorities of pawl.But also can establish a plurality of especially two chains or banded supporting members, they are separately fixed in the outer side edges zone of pawl.Improved stability in this way by the scraper plate conveyer belt of the present invention's design.
Pawl preferably detachably is fixed on one or more supporting members and/or is designed to air-locked.Guarantee that in this way on the one hand the pawl and the employed sifter that are adopted are mated best, available on the other hand new pawl replaces the pawl that has worn and torn.
By the another kind of favourable form of implementation of the present invention, scrape materials and parts and respectively constitute by one section of pawl.Making by equipment of the present invention in this way can be a kind of economic especially design, because no longer need independent member for scraping materials and parts.Especially pawl is designed to pliable and toughly in the section that its formation is scraped materials and parts at least, for example makes with vulcanie.Therefore scraping materials and parts can be adaptive with the sifter surface, thus even to a certain degree inhomogeneities is arranged in the sieve surface, still can guarantee to scrape materials and parts along its whole width and in its whole range of movement the pressure with regulation abut on the surface of sifter.
By the another kind of best form of implementation of the present invention, the section that pawl is scraped materials and parts in its formation at least is designed to wear-resisting and abrasion-resistant coating, for example a polytetrafluorethylecoatings coatings is especially arranged.Pawl constitutes the section of scraping materials and parts in this case, both can be designed to one with pawl, also can be designed as independent member.If scraping materials and parts is designed to independent member, then they preferably detachably are contained on the pawl, can be changed when they wear and tear like this.
By the another kind of favourable form of implementation of the present invention, pawl is scraped the section inadhesive material manufacturing of refusing water of materials and parts at least in its formation.Thereby the particulate that prevents the fusion binding agent sticks on the pawl, otherwise can limit the carrying capacity of segmentation.
By the another kind of best form of implementation of the present invention, sifter especially comprises two screening districts that different sieve apertures are arranged.Level is distinguished in the screening of the sieve aperture of the particulate that reaches different sizes in this way by having different size.Especially these screening districts in series arrange along the direction of motion of segmentation that can be by the sifter apparent motion in this case, are in wherein that to can be compared to most the sieve aperture in the one or more screenings district that is in the contrary direction of motion along the sieve aperture in one or more screenings district of segment movement direction the biggest.Reaching thus when inswept when surface sieve and have particulate than minor diameter at first by sifter, is bigger particulate in next one screening district by sieve subsequently.Therefore, realize the classification of particulate according to the quantity in screening district and the size of sieve aperture by expectation.Classified particulate or can be scattered in accordingly in the different gatherer of the particulate that is used for different sizes with screening district; or for example can be dispersed on the conveyer belt of the motion of being located at the sifter below, on conveyer belt, can generate a fleece in this way along its thickness distribution different size particulate.
By the another kind of favourable form of implementation of the present invention, the scraper plate conveyer belt of circulation is by two deflecting roller guidings, so bottom band section directly moves on the sifter surface, and top band section and sifter surface be separated by regulation distance and especially always to be arranged essentially parallel to sifter mobile outwardly.Can make by equipment of the present invention in this way is a kind of compact especially design.Preferably at least at an end of scraper plate conveyer belt, especially in the deflecting roller zone, establish the material receiving device that is used to accept disallowable particulate in this case.These particulates may relate to the impurity that is present in the bulk material, for example screw or nail; But, those full-sizes that surpass to allow and thereby the agllutination or the particle of sieve aperture that can not be by the sifter maximum also can be picked out and be drained.
By the best form of implementation of another kind of the present invention, at least central floor panel is established in the part between upper and lower band section, wherein, pawl abuts on this central floor panel with constituting a section reverse end of scraping materials and parts with it, so guide along central floor panel on these scraped finishes ground, end when segment movement.Adopt this form of implementation, at first be put into bulk material on the central floor panel by the metering hopper by its charging gear, the position that can be brought to a regulation between the deflecting roller is for certain gone.
In this case, by a kind of best form of implementation, central floor panel can the direction of motion along top band section be extended towards another deflecting roller that is in relative position from one of them deflecting roller, and, face in this another deflecting roller and central floor panel between the end of this another deflecting roller and constitute a zone, its allows particulate along passing through perpendicular to the direction on sifter surface.Especially when this zone design has the sifter of big sieve aperture for another, can finish its size here and surpass the impurity of this screen size or the pre-separation of particle.Have only those particulates that passed through this another sifter just to drop on and be positioned on the sifter of following direction, these particulates are removed by means of conveying device on this sifter.
By the another kind of best form of implementation of the present invention, two scraper plate conveyer belts longitudinally in series are set, wherein, these scraper plate conveyer belts especially are arranged to mutual minute surface symmetry.Advantageously connect one in the charging gear downstream of metering hopper in this case is the distributor of pendulum-type distributor especially in form, especially can supply with two scraper plate conveyer belts by alternately by the particulate that charging gear is discharged from the metering hopper by means of it.Adopt this design particulate to be distributed to two different scraper plate conveyer belts from a metering hopper.Especially when these two scraper plate conveyer belts energy reverse drive, two top band sections can be moved away from each other, and when between top and bottom band section, central floor panel being set by the mode that has illustrated, then be put into particulate on separately the central floor panel and can be transported to the scraper plate conveyer belt and be positioned at reciprocal outer end, and be placed to respectively there on the sifter that is positioned at scraper plate conveyer belt below through distributor.In the screen size that suitably designs these sifters, especially when screen size when the direction of motion of bottom band section increases, can be located at the fleece that forms a symmetry on the conveyer belt that moves below the sifter at one, it has the thin surface layer of a bottom and the thin surface layer on a top, accompanies a thick intermediate layer between these two surface layers.For example also can establish two metering hoppers and replace a distributor, supply particulates to two scraper plate conveyer belts by means of them.
Sifter and/or another sifter are preferably designed as shaker screen or are designed to vibratory sieve in all forms of implementation.Be placed on bulk material on the sifter in this case and further do pine, therefore be positioned at from sieve tiny particulate far away and follow medium sized particulate and arrive sieve aperture rapidly and pass through through sieve aperture.
By the another kind of best form of implementation of the present invention, shaker screen can move back and forth by means of crank driving mechanism.Wherein, the range of shaker screen advantageously between 10cm and 1m, preferably between 30cm and 70cm, especially is about 50cm.
By the motion of the whole shaker screen of its frequency adjustable, make the chip homogenising that is positioned on the screen cloth and by sifting out with the corresponding hierarchical approaches of sieve aperture.In this case, pawl can or move along the surperficial scraped finish of sieving with being separated by a little spacing with it.
Because pawl and shaker screen moves simultaneously and based on the direction of motion that shaker screen changes, make them a little while along with the counter motion a little while of moving together, repeatedly assemble in the front and back of pawl and overturn so be in particulate in the segmentation.
Especially when make shaker screen along the maximum movement speed of throughput direction during greater than the transporting velocity of segmentation by a kind of best form of implementation, if pawl and shaker screen move in the same way, particles agglomerate is in that side of the contrary throughput direction of pawl.Particulate is passed and upset towards the back of pawl.
If the throughput direction of the contrary segmentation of shaker screen also thereby against the direction of motion of pawl moves, particulate rolls in the front of pawl so.
By this repeating scrolling, make particulate in segmentation, realize evenly distributing, thereby make less particulate can be promptly whole amount by being positioned at the segmentation particulate move about and fall towards the surface direction of sieve by sieve aperture.
In addition, by making shaker screen, also improved the self-cleaning effect of sieve with the pawl while but with different speed and direction motion.Because the lower edge of pawl is along the surperficial scraped finish of shaker screen or be arranged to have with it a little spacing, when pawl is inswept, draws together disconnected and extrude by sieve aperture so be stuck in particulate in the sieve aperture.Got rid of the screen cloth possibility of jamming thus.
By the another kind of favourable form of implementation of the present invention, segmentation in the side at least localized design for sealing.Avoid particulate and fine-particle powder side direction to discharge thus from segmentation, thus equipment around in fact keep dustless.
Advantageously especially be provided with sheet packing in the side regions of segmentation, they especially are fixed on the side end face of pawl.Adopt sheet packing can become a kind of simple segmented seal device, also can reequip existing equipment with this seal in a simple manner in this case.
By another kind of best form of implementation, per two along throughput direction in succession seal is local at least overlapping each other, cause a sealing device that extends along the whole width of segmentation thus.The design of adopting this overlap joint is to consider such actual conditions, promptly, when scraper plate conveyer belt that conveying device is designed to circulate, pawl has radially big spacing between inside the edge of a ratio each other radially being in outside edge at it when deflecting roller moves.Because segmentation side district can not adopt fixed sealing device in this case, so advantageously can realize sealing by the seal of overlap joint.In principle seal also can for example be designed to pliable and tough, wherein, this flexible on the one hand can be and pass through for example folding acquisition of concertina on the other hand by certain material behavior.
By another kind of best form of implementation, the arranged outside of segmentation especially is designed to the central seal of sidewall between the band section of upper and lower.In this case preferably by means of this central seal Zone Full between side seal top and bottom band section basically.
Adopt mid seal to make zone between top and the bottom band section on every side with respect to sealing, so further improved the dustless property of surrounding environment by means of this central seal.
A central seal is respectively established in two outsides that are preferably in segmentation, thereby prevents that dust from entering the surrounding environment from the effusion of equipment both sides.
Central authorities' seal seal best and in the side-closed segmentation is connected hermetically, and especially is in sliding wear contact hermetically with it under the situation of seal motion.Whole side district is sealed, so be actually dustless by the side environment of equipment of the present invention by central seal and the continuous basically unified sealing device of forming at the seal of side seal segmentation by one.
In order to prevent that also dust from upwards overflowing from equipment, by another kind of favourable form of implementation, establish above the band section of top especially be designed to the wall section on seal.
By the another kind of favourable form of implementation of the present invention, above segmentation, establish conveying device, the particulate of discharging from the metering hopper can be transported in the zone of sifter top regulation by means of it.The conveying device conveyer belt that especially can be designed to preferably circulate in this case.
Can additionally or substitute the central floor panel that has illustrated and establish conveying device, because the particulate of self-measuring hopper is transported to the function in regulation district, sifter top in the future, no matter still is by means of central floor panel and can realizes equally along the cooperating of the top band section that this central floor panel is moved by means of conveying device.Therefore all that mention belong to advantage and the feature combination of the embodiment with central floor panel, also may reside in the equipment with the conveying device that especially is designed to endless conveyor and thereby belong to claim.For example, by means of conveying device, can take another deflecting roller place that is in relative position to, and pass the scraper plate conveyer belt there and deliver on the surface of sifter delivering to the particulate in one of them deflecting roller zone on the conveying device by the metering hopper.
By the favourable form of implementation of another kind of the present invention, by a kind of equipment that is used for scattering particulate of the present invention, classifying equipoment is designed to and can be along the longitudinal movement with respect to conveyer belt.Therefore when especially being provided with the forcing press of periodic duty of compressed fibre net in its downstream, by classifying equipoment is moved just at the next fleece of distribution, so next fleece also scatters the good forcing press that also can directly infeed periodic duty fully when finishing compacting with respect to conveyer belt.
In addition, be used to scatter the classifying equipoment of one or more surface layers by of the present invention except one or more, can also be provided for scattering the intermediate layer dispersing roller head in fleece intermediate layer by the present invention.
