Description

Blande- og knainnretning. Mixing and kneading device.

Foreliggende oppfinnelse angår en blande- og knainnretning . The present invention relates to a mixing and kneading device.

Det er allerede kjent blande- og knainnretninger som There are already known mixing and kneading devices such as

har en i en kapsling roterende og samtidig frem-og tilbakegående aksel som bærer rore- og knaorganer som samvirker med i kapslingen anordnede knafremspring i et blanderom, idet akselens frem-og tilbakegående bevegelse er slik begrenset at rore- og knaorganene ikke kan treffe knafremspringene og idet der for dreiebevegelsen og for den frem-og tilbakegående bevegelse av akselen er anordnet fullstendig uavhengige drivmidler, og hvor knaakselen er forbundet med en drivaksel som drives ved hjelp av en drivmotor under mellomkobling av en tannhjulsutveksling og at der for akselens frem og tilbakegående bevegelse er an- has a shaft rotating in an enclosure and at the same time reciprocating, which carries rudder and cam members that interact with cam projections arranged in the casing in a mixing chamber, the shaft's reciprocating movement being so limited that the rudder and cam members cannot hit the cam projections and in that completely independent drive means are arranged for the turning movement and for the reciprocating movement of the axle, and where the crankshaft is connected to a drive shaft which is driven by means of a drive motor under the intermediate coupling of a gear transmission and that for the reciprocating movement of the axle there is an-

ordnet et av en motor påvirkbart styreorgan som virker avvekslende i begge retninger-i form a<y> en aksial forskyvning på et arbeidsstempel som omgir akselen koaksialt. " .... arranged a control device actuated by a motor which acts alternately in both directions-in the form of a <y> an axial displacement on a working piston which surrounds the shaft coaxially. "...

Den samtidig roterende og frem- og tilbakegående beve*i • geise gir en sinuskurveliknende bane , idet material-tgj ennomgangen over et område er proporsjonal med akselens omdreiningstall. Den roterende og samtidig frem—og tilbakegående bevegelse av akselen ble frembrakt ved hjelp av en spesialdrivanordning, idet det gitte forhold av be-arbeidet materiale til blande- og knaytelse bare kunne forandres innenfor visse grenser. Således har det allerede vært foreslått å anvende et knaorgan med helt eller delvis sluttede snekkegjenger for å oppnå The simultaneously rotating and reciprocating movement produces a path similar to a sine curve, as the passage of material over an area is proportional to the number of revolutions of the shaft. The rotating and simultaneous forward and backward movement of the shaft was brought about by means of a special drive device, as the given ratio of processed material to mixing and kneading performance could only be changed within certain limits. Thus, it has already been proposed to use a knurling device with fully or partially closed screw threads to achieve

en ytterligere lengdestromning av materialet. En annen losning besto i at det ved skråstilling av snekkeskovlene i forhold til skruelinjen, på hvilken de er anordnet, kunne bevirkes en merkbar okning av materi-algjennomgangen. Denne okning opptråtte ofte allerede ved skrå ut-forelse av skovlekantene. En struping av gjennomgangen ved et gitt omdreiningstall kunne oppnåes ved fortykning av akselkjernen eller ved anordning av oppdemningselementer. a further longitudinal flow of the material. Another solution consisted in that by tilting the screw vanes in relation to the screw line, on which they are arranged, a noticeable increase in the material throughput could be effected. This increase often already occurred when the blade edges were slanted. A throttling of the passage at a given rpm could be achieved by thickening the axle core or by arranging damming elements.

Det skal dessuten spesielt vises til at ved alle hittil kjente blande- og knainnretninger med skovleliknende avbrutte snekkegjenger er forholdet mellom slagtall og omdreiningstall 1:1. It should also be pointed out in particular that for all hitherto known mixing and kneading devices with shovel-like interrupted screw threads, the ratio between stroke rate and revolution rate is 1:1.

Formålet med oppfinnelsen er å skaffe en blande- og knainnretning, hvor forholdet mellom g'jennomgangsytelsen og blande- og knaeffekten kan tilpasses kravene innenfor et storre område og med enkle midler på en trinnlos måte, slik dette f.eks. er påkrevet for mange kjemiske reaksjonsprosesser. The purpose of the invention is to provide a mixing and kneading device, where the relationship between the throughput performance and the mixing and kneading effect can be adapted to the requirements within a larger area and with simple means in a stepless manner, as this e.g. is required for many chemical reaction processes.

Blande- og knainnretningen ifolg,e oppfinnelsen utmerker seg ved at arbeidsstemplet er utformet som en hulaksel og omslutter drivakselen på en slik måte at den kan rotere fritt, idet der ved begge ender av arbeidsstemplet er anordnet med akselen fast forbundne glideringer, mot hvilke arbeidsstemplets endesidér hviler under mellom-, kobling av kulelagere, og arbeidsstempelet står under virkningen av et fjærorgan som soker å forskyve arbeidsstemplet mot den ene aksiale endestilling, idet styreventilen omfatter en styresylinder som over trykkledninger er forbundet med arbeidsstemplets arbeidssylinder. The mixing and kneading device according to the invention is distinguished by the fact that the working piston is designed as a hollow shaft and surrounds the drive shaft in such a way that it can rotate freely, since at both ends of the working piston there are sliding rings firmly connected to the shaft, against which the end sides of the working piston rests under intermediate coupling of ball bearings, and the working piston is under the action of a spring element which seeks to displace the working piston towards the one axial end position, the control valve comprising a control cylinder which is connected via pressure lines to the working piston's working cylinder.

Avfasingen av de forreste kanter har ved denne arbeids-måte praktisk talt ikke lenger noen innflytelse. Hvis knaakselen roterer hurtig og den frem- og tilbakegående bevegelse foregår langsomt, oppstår en gunstig stempelstromningsvirkning i materialstrommen, hvorved den midlere oppholdstid og dermed gjennomgangsmengden kan på-' virkes. The chamfering of the front edges practically no longer has any influence in this way of working. If the crankshaft rotates quickly and the reciprocating movement takes place slowly, a favorable piston flow effect occurs in the material flow, whereby the average residence time and thus the throughput can be influenced.

Ved forandringen av antallet slag pr. tidsenhet og ved reguleringen av slagbevegelsens hastighet, idet forskjellige slagbeve-gelseshastigheter kan holdes fremover og bakover, kan den onskede gjen-nomgangsmengde innstilles trinnlost. Blande- og knaeffekten er inn-stillbar tilnærmet uavhengig av slaget ved forandring av omdreinings-tallet.' By changing the number of strokes per unit of time and by regulating the speed of the impact movement, since different impact movement speeds can be maintained forwards and backwards, the desired throughput amount can be set steplessly. The mixing and kneading effect can be adjusted almost independently of the stroke by changing the number of revolutions.

Et utforelseseksempel på oppfinnelsen er vist på teg-ningene, hvor fig. 1 er et aksialsnitt av en blande- og knainnretning uten drivanordning, fig. 2 viser en avvikling av knaakselen på fig. 1 An embodiment of the invention is shown in the drawings, where fig. 1 is an axial section of a mixing and kneading device without drive device, fig. 2 shows an unwinding of the crankshaft in fig. 1

fer og med et innlop 3 for væsker, pastaer eller fluidiserte pulvere. fer and with an inlet 3 for liquids, pastes or fluidized powders.

Ved en annen ende av kapslingen befinner seg en utlripsdyse 4. Langs •kapslingens vegg er anordnet knafremspring 5 som kan stikkes inn uten-fra gjennom tilsvarende åpninger og sikres. Derved er det mulig å forsyne knafremspringene eller enkelte av disse med boringer som kan tjene til ytterligere tilforsel av materiale. At another end of the enclosure there is a discharge nozzle 4. Along the wall of the enclosure there is a knob projection 5 which can be inserted from the outside through corresponding openings and secured. Thereby, it is possible to provide the knob projections or some of these with bores that can serve for further supply of material.

I kapslingen 1 er anordnet en knaaksel 6 som hensikts-messig er lagret på drivsiden (til venstre) og kan være stottet i knakapslingen. Aksellagringen på drivsiden er betegnet med 7. I om-rådet for det traktformede innlop er det på akselen 6 anordnet snekke-skruevinninger 8, ved hjelp av hvilke materialet trekkes inn i blanderommet 9. I tilknytning til snekkeskruevinningene er det på akselen anordnet knaskovler eller vinger 1D. De nevnte knafremspring 5 er fordelt i samsvar med vingene 10, eventuelt forskutt skruelinjeformet i flere rekker. I blanderommet 9 blir materialet blandet og knadd særlig intenst, idet som avslutning av blanderommet er satt en oppdemningsring 11 inn i kapslingen 1. Det bearbeidede produkt stotes over denne oppdemningsring 11 inn i kapslingens 1 rom 13. Rommet 13 A crank shaft 6 is arranged in the housing 1 which is conveniently stored on the drive side (left) and can be supported in the crank housing. The shaft bearing on the drive side is denoted by 7. In the area of the funnel-shaped inlet, worm-screw windings 8 are arranged on the shaft 6, with the help of which the material is pulled into the mixing chamber 9. In connection with the worm-screw windings, knurling vanes or wings are arranged on the shaft 1D. The aforementioned knob projections 5 are distributed in accordance with the wings 10, possibly offset helically in several rows. In the mixing chamber 9, the material is mixed and kneaded particularly intensively, as at the end of the mixing chamber a damming ring 11 is inserted into the enclosure 1. The processed product is pushed over this damming ring 11 into the chamber 13 of the enclosure 1. The chamber 13

er utstyrt med en avlang avgassingssjakt 14 som muliggjor avsugning av flyktige reaksjonsprodukter. Denne avgassingssjakt dekkes ved hjelp av et inspeksjonsglass 20. Avslutningen av avgassingsrommet 13 is equipped with an oblong degassing shaft 14 which enables the extraction of volatile reaction products. This degassing shaft is covered by means of an inspection glass 20. The termination of the degassing space 13

Det skal - videre nevnes at akselen 6 er utformet som hul aksel og har en tilforselsledning. 16 og en. returledning 17 for et varmemedium. Det skal også nevnes den med 18 betegnede doseringspumpe, ved hjelp av hvilken en væskekomponent drives gjennom en ledning 19 og inn gjennom tillopet 3.1 It should - further be mentioned that the shaft 6 is designed as a hollow shaft and has a supply line. 16 and one. return line 17 for a heating medium. Mention should also be made of the dosing pump denoted by 18, by means of which a liquid component is driven through a line 19 and into the inlet 3.1

På fig. 2 er akselen b vist avviklet, idet stillingene In fig. 2, the shaft b is shown unwound, as the positions

av knafremspringene 5 i.forhold til akselen er angitt ved forskjellige kombinasjoner av rotasjons- og slagbevegelser. Linjen a fremkommer når man innstiller en aksialbevegelse for hver omdreining. Linjen b viser to aksialbevegelser for hver omdreining og linjen c likeledes to bevegelser, men med stillstand i endepunktene over 15° omdreining. Det er tydelig hvordan man er i stand til å regulere hele den periodisk tilbakevendende avstrykervirkning over hele snekkevingebredden. of the knob projections 5 in relation to the axle is indicated by different combinations of rotational and impact movements. The line a appears when you set an axial movement for each revolution. Line b shows two axial movements for each revolution and line c likewise two movements, but with standstill at the end points over 15° revolution. It is clear how one is able to regulate the entire periodically recurring wiper action over the entire worm wing width.

På fig. 3 er skjematisk vist drivanordningen. Den ende In fig. 3 schematically shows the drive device. The end

av knaakselen 6 som rager ut av kapslingen 1, er forbundet med en drivaksel 21 som strekker seg med samme akse som knaakselen 6. Drivakselen 21 er fort i glidela og står i forbindelse med en drivmotor 22. Drivmotoren 22 er forsynt med en tannhjulsutveksling 23 of the crankshaft 6 that protrudes from the housing 1 is connected to a drive shaft 21 which extends along the same axis as the crankshaft 6. The drive shaft 21 is fast in the sliding part and is connected to a drive motor 22. The drive motor 22 is equipped with a gear transmission 23

som har inngrep med et på akselen 21 med kile festet tannhjul 24. Den ende av akselen 21 som rager ut av tannhjulsutvekslingen, er forsynt med tilkoblinger 25 og 26 for et varmemedium til oppvarming av akselen. which engages with a toothed wheel 24 fixed to the shaft 21 with a wedge. The end of the shaft 21 that protrudes from the gear exchange is provided with connections 25 and 26 for a heating medium for heating the shaft.

Akselens frem- og tilbakegående bevegelse frembringes The reciprocating movement of the shaft is produced

ved hjelp av en separat drivanordning som har en motor 27. Denne motor er trinnlost regulerbar og har en drivaksel 28 som bærer en utskiftbar kurveskive 29. Kurveskivens virksomme bane er slik valgt at slagbevegelsen foregår hurtig i drivretningen og returlopet foregår langsomt. Mot kurveskiven 29 ligger der an et hode 30 på et styreorgan som er tatt opp i en styresylinder 31. Styreorganet er utformet som en styreventil 32. Til styreventilen 32 er koblet en trykkpumpé 33 som drives ved hjelp av motoren 27. Dessuten står styreorganet i forbindelse med en, arbeidssylinder 34 som omslutter drivakselen 21 by means of a separate drive device which has a motor 27. This motor is continuously adjustable and has a drive shaft 28 which carries a replaceable cam disc 29. The effective path of the cam disc is chosen so that the impact movement takes place quickly in the drive direction and the return stroke takes place slowly. Against the cam disc 29 lies a head 30 of a control member which is taken up in a control cylinder 31. The control member is designed as a control valve 32. A pressure pump 33 is connected to the control valve 32, which is driven by means of the motor 27. The control member is also connected with a working cylinder 34 which encloses the drive shaft 21

med samme akse og i hvilken arbeidssylinder er glidbart lagret et arbeidsstempel 35. Arbeidsstemplet 35 omfatter som hulaksel drivakselen 21, slik at sistnevnte kan rotere fritt. Drivakselen 21 bærer glideringer 36, mellom hvilke arbeidsstemplet 35 samt kulelagere 37 with the same axis and in which working cylinder a working piston 35 is slidably mounted. The working piston 35 comprises the drive shaft 21 as a hollow shaft, so that the latter can rotate freely. The drive shaft 21 carries slip rings 36, between which the working piston 35 and ball bearings 37

er anordnet. is arranged.

Alt etter styreventilens 32 stilling strommer hydrau-likkolje enten gjennom ledningen 38 eller gjennom ledningen 39 inn i arbeidssylinderen 34, hvorved arbeidsstempelet 35 forskyves mot htiyre eller mot venstre. Da arbeidsstempelet ikke deltar i dreiebevegelsen, er der bygget inn fjærer 4-0 for utjevning av skyvekrefter i hydraulikk-sylinderen. Depending on the position of the control valve 32, hydraulic oil flows either through the line 38 or through the line 39 into the working cylinder 34, whereby the working piston 35 is displaced to the right or to the left. As the working piston does not participate in the turning movement, springs 4-0 have been built in to equalize thrust forces in the hydraulic cylinder.

For finregulering av slagbevegelsen er der anordnet en grenseregulator som har en stangoverforing 41. Denne står ved den ene ende i forbindelse med en foring 42 på arbeidsstempelet 35 og er ved den annen ende svingbart lagret ved 43. For fine regulation of the impact movement, a limit regulator is arranged which has a rod over-lining 41. This is at one end in connection with a lining 42 on the working piston 35 and is pivotably supported at 43 at the other end.

Midten av stangen er forbundet med styreventilen 32. The middle of the rod is connected to the control valve 32.

Ved hjelp av grenseregulatoren holdes oljestrommen sålenge vedlike With the help of the limit regulator, the oil flow is maintained for as long as possible

til sluttstillingene for arbeidsstemplet er nådd. Alt etter, kurveskivens 29 form kan den ene eller begge sluttstillinger holdes f.eks. over 15° av kurveskivens omdreining for oljestrommens retning forandres med styreventilen 32. until the end positions of the work stamp are reached. Depending on the shape of the cam disc 29, one or both end positions can be held, e.g. above 15° of the rotation of the cam disc for the direction of the oil flow is changed with the control valve 32.

Den hydrauliske drift av akselens 21 frem- og tilbakegående bevegelse avlastes vesentlig ved hjelp av den nevnte fjær 40, idet denne leverer ytterligere kraft i utstotningsretningen og lagrer kraft i returslaget. The hydraulic operation of the reciprocating movement of the shaft 21 is substantially relieved by means of the aforementioned spring 40, as this supplies additional force in the ejection direction and stores force in the return stroke.

På fig. 5 og 6 er vist et ytterligere utforelseseksempel. Blande- og knainnretningen på fig. 5 har en på et fundament 101 anordnet, sylindrisk kapsling 102 med innlopsåpning 103 og utlopsåp-ning 104, hvori en roterende og samtidig frem- og tilbakegående aksel 105 er anordnet. Akselen 105 er forsynt med parvis diametralt mot-stående anordnede, skovleliknende rore- og knavinger 106, idet et av-strykerfremspring 107 samvirker med hvert par rore- og knavinger 106, hvilke fremspring 107 er festet oventil til venstre i kapslingen 102 når akselen 105 roterer med urviserens retning. Videre er kapslingen 102 forsynt med en vakuumtilkobling 108. In fig. 5 and 6 show a further exemplary embodiment. The mixing and kneading device in fig. 5 has a cylindrical enclosure 102 arranged on a foundation 101 with inlet opening 103 and outlet opening 104, in which a rotating and simultaneously reciprocating shaft 105 is arranged. The shaft 105 is provided with pairs of diametrically opposed, paddle-like rudder and knobs 106, with a scraper projection 107 cooperating with each pair of rudder and knobs 106, which projections 107 are attached to the upper left in the housing 102 when the shaft 105 rotates in a clockwise direction. Furthermore, the enclosure 102 is provided with a vacuum connection 108.

For drift av akselen 105 foreligger en drivmotor med tannhjulsutveksling, hvilke deler er anbrakt i en i aksial retning frem og tilbake bevegelig kapsling 109 som ved hjelp av pendelstotter 110 er forskyvbar på fundamentet 101 i pilens P retning. Tannhjuls-utvekslingens utgående aksel 111 er lagret ved 112 og står i forbindelse med akselen 105. For operation of the axle 105, there is a drive motor with gear transmission, the parts of which are placed in an axially moving back and forth housing 109 which, by means of pendulum supports 110, is displaceable on the foundation 101 in the direction of the arrow P. The output shaft 111 of the pinion transmission is supported at 112 and is connected to the shaft 105.

For å frembringe akselens 105 frem- og tilbakegående bevegelse foreligger en stempelinnretning 113 som har et i en stasjo-nær sylinder 114 anordnet, hydraulisk eller pneumatisk påvirkbart stempel" 1.15'.. Stempelstangen 116 har mellomlagringer ved 117 og er tilkoblet kapslingen 109,:slik at ved frem- og tilbakegående bevegelse av stempelet 115 blir kapslingen 109 skjovet frem og tilbake på pen-delstottene 110, hvorved også den,roterende aksel 105 får en frem- og tilbakegående bevegelse, under hvilken tannhjulsutvekslingen vedvar-ende forblir i fast inngrep med akselens 105 tannkrans uten å måtte oppta slag ved den uregelmessig glidende frem- og tilbakegående bevegelse. Både kapslingen 102 og akselen 105 er utformet med mulighet for oppvarming. In order to produce the reciprocating movement of the shaft 105, there is a piston device 113 which has a hydraulically or pneumatically actuated piston "1.15" arranged in a stationary cylinder 114. The piston rod 116 has intermediate bearings at 117 and is connected to the housing 109, as follows that during the reciprocating movement of the piston 115, the housing 109 is pushed back and forth on the pendulum supports 110, whereby the rotating shaft 105 also receives a reciprocating movement, during which the gear transmission remains permanently in fixed engagement with the shaft's 105 ring gear without having to absorb impact from the irregularly sliding reciprocating motion.Both the casing 102 and the shaft 105 are designed with the possibility of heating.

Under drift fylles kapslingen 102 ca. 65 % med det materiale som skal bearbeides, opp til nivået 118, idet der over dette nivå gjenstår et rom 119, hvor det hersker vakuum. During operation, the enclosure 102 is filled approx. 65% with the material to be processed, up to level 118, as above this level there remains a room 119, where vacuum prevails.

Oppholdstiden og gjennomgangsytelsen kan meget enkelt varieres ved forandring av slagbevegelsens rekkefolge. I dette til-felle foregår slagbevegelsen fremover ved horisontal vingestilling, slik at de to rore- og knavinger 116 i hvert par transporterer fullt, mens ved returslaget er vingestillingen vertikal, slik at den bakover virkende transportytelse bare er ca. 50 til 55 % av ytelsen fremover. Ved forandring av slagbevegelsens rekkefolge kan transportytelsen fremover og bakover varieres etter onske innenfor de ovennnevnte ver-dier. The residence time and the pass-through performance can be varied very easily by changing the sequence of the stroke movement. In this case, the stroke movement takes place forward with a horizontal wing position, so that the two rudder and knobs 116 in each pair transport fully, while during the return stroke the wing position is vertical, so that the backward acting transport performance is only approx. 50 to 55% of performance going forward. By changing the sequence of the impact movement, the forward and backward transport performance can be varied as desired within the above-mentioned values.

På den beskrevne måte foregår knaakselens frem- og tilbakegående bevegelse fullstendig uavhengig av den roterende bevegelse, idet blande- og knavirkningen kan påvirkes avgjorende ved forandring av akselens omdreiningstall og antallet slagbevegelser. Blande- og knavirkningen forblir innenfor et stort område tilnærmet uavhengig av slagbevegelsen og innstilles bare ved forandring av omdreinings-tallet. For driften kan anvendes enkle og pålitelige regulerbare mo-torer og rotasjons- og eksenterdrivanordninger som fåes i normal ut-forelse. In the manner described, the reciprocating movement of the crankshaft takes place completely independently of the rotary movement, as the mixing and kneading action can be decisively influenced by changing the number of revolutions of the axle and the number of impact movements. The mixing and kneading effect remains within a large range almost independently of the impact movement and is only adjusted by changing the number of revolutions. For operation, simple and reliable adjustable motors and rotation and eccentric drive devices can be used, which are available in normal design.
