Description
Oppfinnelsen angår en cellehjulssluse ifølge patent-kravets innledning. The invention relates to a cell wheel lock according to the preamble of the patent claim.
Cellehjulssluser for eventuelt også dosert innslu-sing av massegods i pneumatiske transportanlegg har lenge vært kjent, både i form av fordelingssluser hvor massegods tilføres vertikalt ovenfra og medbringes en knapp halv omdreining i cellehjulet, hvoretter det faller vertikalt ned-over (sammenlign eksempelvis DE 608765), og også i form av gjennomblåsningssluser hvor det på samme måte tilførte massegods etter en knapp halv omdreining av cellehjulet, blåses ved hjelp av den horisontalt i et flenslokk innblåste tran-sportluft umiddelbart til den transportledning som utgår fra det ovenfor liggende flenslokk (sammenlign DE 1 925 915). Cell wheel sluices for possibly also dosed intake of bulk material in pneumatic transport systems have long been known, both in the form of distribution sluices where bulk material is supplied vertically from above and is brought along for just under half a revolution in the cell wheel, after which it falls vertically downwards (compare, for example, DE 608765) , and also in the form of blow-through sluices where the bulk material supplied in the same way after barely half a revolution of the cell wheel is blown with the help of the transport air blown horizontally into a flange cover immediately to the transport line that emanates from the above flange cover (compare DE 1 925 915).
Begge slusetyper har spesielle ulemper og fordeler. Uttaksslusen muliggjør en høy belastning, kan tilpasses mellom sluseuttaket og transportledningen til nesten enhver dia-meter av transportledninger ved hjelp av egnede overgangs-stykker og er forholdsvis motstandsdyktig overfor slitasje. Ved massegods som har en tendens til å pakke seg oppstår imidlertid en ufullstendig tømming av cellene, likeledes også ved stor trykkdifferanse mellom inntaks- og uttakssiden. Omvendt er gjennomblåsningsslusen på grunn av trykkluftut-taket mindre ømfindtlig overfor massegods som lett pakkes og mot høyere trykkdifferanser mellom inntaks- og uttakssiden, tillater imidlertid kun en forholdsvis liten belastning, et fritt valg av diametre for transportledningen kun innenfor små grenser og er især på uttakssiden utsatt for sterk slitasje. I tilfelle det ikke foreligger spesielle tungtveiende forutsetninger, velges derfor vanligvis uttaksslusen. Both lock types have special disadvantages and advantages. The outlet lock enables a high load, can be adapted between the lock outlet and the transport line to almost any diameter of transport lines by means of suitable transition pieces and is relatively resistant to wear. In the case of bulk goods that tend to pack, however, an incomplete emptying of the cells occurs, likewise also in the case of a large pressure difference between the intake and outlet side. Conversely, due to the compressed air outlet, the blow-through sluice is less sensitive to bulk goods that are easily packed and to higher pressure differences between the intake and outlet side, however only allows a relatively small load, a free choice of diameters for the transport line only within small limits and is especially on the outlet side exposed to heavy wear. In the event that there are no particularly weighty conditions, the withdrawal lock is therefore usually chosen.
Også blandingsformer av de to slusetyper er alle-rede kjent. Således viser DE 597492 en uttakssluse hvor cellehjulet for forbedret tømming av celleneog for rensing av spalten mellom slusehuset og cellehjulet, er utformet lukket i enden og hvor de to endevegger i hver celle har en i cellebunnen utmunnende kanal som ved cellen dreid i uttaks-stillingen, kommer til dekning med en i den nedre del av de to flenslokk i huset anordnet trykkluftmatekanal, slik at det produkt som befinner seg i cellen tømmes ut ved tyngde-kraften med bistand av den innblåste trykkluft. Mixed forms of the two lock types are also already known. Thus, DE 597492 shows an outlet lock where the cell wheel for improved emptying of the cells and for cleaning the gap between the lock housing and the cell wheel is designed closed at the end and where the two end walls in each cell have a channel opening into the bottom of the cell which is turned at the cell in the outlet position, comes to cover with a compressed air supply channel arranged in the lower part of the two flange covers in the housing, so that the product in the cell is emptied by gravity with the assistance of the blown-in compressed air.
Fra CH 339963 er en uttakssluse av den innledningsvis nevnte type kjent, hvor cellehjulet for forbedring av uttaket av massegods som tenderer til å pakke seg, er åpen i enden og de enkelte celler i deres tømmestilling kommer til dekking med et i slusehusets flenslokk horisontalt utmunnende rør, hvorigjennom all den trykkluft som behøves for den etterfølgende videretransport, blåses inn i cellen. From CH 339963, an outlet sluice of the type mentioned at the outset is known, where the cell wheel, for improving the removal of bulk goods that tend to pack, is open at the end and the individual cells in their emptying position are covered by a tube opening horizontally into the lock housing's flange cover , through which all the compressed air needed for the subsequent onward transport is blown into the cell.
Alle kjente cellehjulssluser har det felles at uttaket av massegodset på grunn av den av cellene fremkomne porsjonerte tilførsel, i tømmingsområdet ikke foregår ens-artet, men med en frekvens som er avhengig av cellehjulets turtall og antallet celler. Denne pulserende tømming er riktignok betydningsløs for de fleste brukstilfeller, men kan på bestemte områder, eksempelvis ved den doserte mating av brennere med -pulverformede brennstoffer som eksempelvis kullstøv, ikke aksepteres da en økonomisk forbrenning forut-setter en stabil flamme. All known cell wheel sluices have in common that, due to the portioned supply produced by the cells, the removal of the bulk material in the emptying area does not take place uniformly, but with a frequency that depends on the speed of the cell wheel and the number of cells. This pulsating emptying is admittedly insignificant for most cases of use, but cannot be accepted in certain areas, for example with the metered feeding of burners with powdered fuels such as coal dust, as an economical combustion requires a stable flame.
Oppfinnelsen tar sikte på å løse den oppgave å The invention aims to solve the task of
videreutvikle en cellhjulssluse av den innledningsvis nevnte type slik at de typiske fordeler ved en uttakssluse bibehol-des med samtidig i det vesentlig ersartet massegodsstrøm ved sluseuttaket... (konstant over tid) . further develop a cell wheel lock of the type mentioned at the outset so that the typical advantages of an outlet lock are maintained with at the same time an essentially changed bulk cargo flow at the lock outlet... (constant over time) .
Denne oppgave løses ifølge oppfinnelsen ved at det tømmetverrsnitt som cellene beveges over, er mindre enn tøm-mes jaktens åpne tverrsnitt. This task is solved according to the invention in that the empty cross-section over which the cells are moved is smaller than the open cross-section of the empty hunt.
Mens man tidligere logisk nok bestrebet seg på å gjøre tømmetverrsnittet så stort som mulig for å oppnå en så. hurtig og fullstendig tømming sem mulig: av de celler som etter hverandre passerte tømmesjakten, dvs. med hensyn til de konstruktive trekk, å gjøre tømmetverrsnittet lik tømme-sjaktens åpne tverrsnitt, har det overraskende nok vist seg at en bevisst forminskning av tømmetverrsnittet i■forbindelse med den trykkluft som blåses inn i cellene ved tømmestillin-gene, fullstendig eller i det minste tilnærmet fullstendig opphever de pulseringer som hittil er oppstått og de herav resulterende tidsmessige svingninger av massegodsmengden til den tilkoblede transportledning, også ved forholdsmessig lave turtall for cellehjulet. De nøyaktige årsaker for denne effekt er i detalj ennå ikke kjente. Whereas previously, logically enough, efforts were made to make the timber cross-section as large as possible in order to achieve a rapid and complete emptying as possible: of the cells that successively passed the emptying chute, i.e. with regard to the constructive features, making the emptying cross-section equal to the open cross-section of the emptying chute, it has surprisingly turned out that a deliberate reduction of the emptying cross-section in ■connection with the compressed air that is blown into the cells at the emptying stations, completely or at least almost completely cancels the pulsations that have occurred up to now and the resulting temporal fluctuations of the quantity of bulk goods to the connected transport line, also at relatively low revolutions of the cell wheel. The exact reasons for this effect are not yet known in detail.
Både typen og stedet for luftinnblåsningen i cellene, samt også formen for det frie tømmetverrsnitt påvirker graden av ensartethet for tømmingen av massegodset. Underkravene er rettet mot dette trekk. Both the type and location of the air injection into the cells, as well as the shape of the free emptying cross-section, affect the degree of uniformity for the emptying of bulk goods. The sub-requirements are aimed at this feature.
Spesielt skal fremheves den utførelse som er omtalt i krav 5 hvor trykkluftinnblåsningen foregår fra begge flenslokk, da det herved ikke bare oppnås en spesielt intensiv oppdeling av massegodset, men massegodset holdes også i det store og hele borte fra cellehjulets endesider,(i tilfelle det handler om et cellehjul som har endevegger nær aksen) og også fra flenslokkenes indre flater slik at slitasjen ned-settes sterkt i disse områder. Particular emphasis should be placed on the design mentioned in claim 5 where the compressed air injection takes place from both flange covers, as this not only achieves a particularly intensive division of the bulk material, but the bulk material is also largely kept away from the end sides of the cell wheel, (in the event that about a cellular wheel that has end walls close to the axis) and also from the inner surfaces of the flange covers so that wear is greatly reduced in these areas.
Spesielt foretrukket er fortsatt den i krav 12 an-gitte symmetriske utforming av det frie tømmetverrsnitt, frem-for alt i forbindelse med dobbeltsidig trykkluftinnblåsing da på denne måte en optimal ensartethet av massegodsstrømmen i sluseuttaket oppnås, også når det benyttes et cellehjul med forholdsmessig få celler.og med lave turtall. Particularly preferred is still the symmetrical design of the free discharge cross-section specified in claim 12, above all in connection with double-sided compressed air blowing, as in this way an optimal uniformity of the flow of bulk goods in the lock outlet is achieved, also when a cell wheel with relatively few cells is used .and at low revs.
Tegningen viser eksempler på utførelser av en cellehjuissluse ifølge oppfinnelsen,'hvor figur 1 viser en første utførelse perspektivisk, figur 2 viser et lengdesnitt gjennom en cellehjuissluse ifølge figur 1, og figur 3-7 viser ulike riss "X" av slusen ifølge figur 2, med flere hen-siktsmessige utforminger av tømmetverrsnittet. The drawing shows examples of designs of a cell housing lock according to the invention, where figure 1 shows a first embodiment in perspective, figure 2 shows a longitudinal section through a cell housing lock according to figure 1, and figures 3-7 show different views "X" of the lock according to figure 2, with several expedient designs of the timber cross-section.
Cellehjulsslusen på figur 1 består av et slusehus 1 med en inntakssjakt 2, en uttakssjakt 3, to flenslokk 4, 5 og et generelt med 6 betegnet cellehjul på hvis aksel 7 som er opplagret i flenslokkene 4, 5,-steg 8 er påsveist som begrenser de enkelte celler. Cellehjulet 6 dreier i pilens 9 retning. De ovenfra med massegods fylte celler beveges derved etter hverandre forbi uttakssjaktens 3 område. Mens denne uttakssjakts 3 totale åpne tverrsnitt ved de hittil kjente cellehjulssluser danner uttakstverrsnittet, er ved cellehjulsslusen ifølge oppfinnelsen uttakssjakten delvis dekket slik at kun åpningen 10 forblir som fritt uttakstverrsnitt. Via dette frie uttakstverrsnitt blåses massegodset ved hjelp av via en åpning 11 i flenslokket 5 innblåst trykkluft Vli pilens 18 retning under medvirkning av tyngdekraf-ten . The cell wheel lock in figure 1 consists of a lock housing 1 with an intake shaft 2, an outlet shaft 3, two flanged covers 4, 5 and a generally designated 6 cell wheel on whose shaft 7, which is stored in the flanged covers 4, 5, step 8 is welded on which limits the individual cells. The cell wheel 6 rotates in the direction of the arrow 9. The cells filled from above with bulk material are thereby moved one after the other past the area of the outlet shaft 3. While the total open cross-section of this outlet shaft 3 in the hitherto known cell wheel locks forms the outlet cross-section, in the cell wheel lock according to the invention the outlet shaft is partially covered so that only the opening 10 remains as a free outlet cross-section. Via this free outlet cross-section, the bulk material is blown with the help of compressed air blown in via an opening 11 in the flange cover 5 in the direction of the arrow 18 under the influence of gravity.
Lengdesnittet ifølge figur 2 viser at åpningen 11The longitudinal section according to Figure 2 shows that the opening 11
er utformet som tilkoblingsstuss for trykkluft. Den venstre halvdel av figur 2 viser forøvrig en i forhold til figur 1 is designed as a connecting piece for compressed air. The left half of Figure 2 also shows a comparison to Figure 1
noe endret cellhjulssluse da også flenslokket 4 som ligger overfor flenslokket 5 med åpningen 1, har en åpning 12 for innblåsing av trykkluft, idet denne åpnings 12 akse er slik orientert at trykkluftstrømmen er rettet mot cellehjulsakselen 7, altså mot den enkelte celles bunnområde.. Videre har cellehjulet her en endevegg 13 nær akselen, som begrenser et kam-mer 14 sammen med en'utsparing i flenslokket 4, med hvilket på somewhat changed cell wheel lock as also the flange cover 4 which lies opposite the flange cover 5 with the opening 1, has an opening 12 for blowing in compressed air, the axis of this opening 12 being oriented in such a way that the flow of compressed air is directed towards the cell wheel shaft 7, i.e. towards the bottom area of the individual cell.. Furthermore the cell wheel here has an end wall 13 close to the axle, which limits a chamber 14 together with a recess in the flange cover 4, with which on
den ene side åpningen 12 er forbundet og på den annen side entilkobling 15 for ren luft munner ut=slik at den trykkluft som tilføres via denne tilkobling først spyler fritt cellehjulsakselens 7 lager for massegodsstøv, hhv. bygger opp et overtrykk i kammeret 14 som hindrer tilgang på massegodsstøv og således understøtter massegodstransporten fra vedkommende celle via åpningen 12. on one side the opening 12 is connected and on the other side a connection 15 for clean air opens = so that the compressed air supplied via this connection first freely flushes the cell wheel shaft's 7 bearing for bulk material dust, respectively. builds up an overpressure in the chamber 14 which prevents access to bulk material dust and thus supports the bulk material transport from the relevant cell via the opening 12.
Figur 3-7 viser en cellehjuissluse tilsvarende figurFigure 3-7 shows a cell housing lock corresponding to the figure
2 i riss "X", med andre ord et grunnriss mot sluseuttaket 3, idet pilene viser cellehjulets dreieretning. Slik det frem-går herav kan de forskjellige, dels symmetriske, dels usymme-triske former av uttakstverrsnittet oppnås ved tilsvarende utformede avdekkinger 3a-3f av sluseuttaket 3, idet disse avdekkinger enten kan foreligge i ett stykke med sluseuttaket 3 eller også (se figur 1) med slusehuset 1. De symmetriske utforminger tilsvarende figur 5-7 benyttes fortrinnsvis i forbindelse med en trykkluftinnblåsning fra begge flenslokk. 2 in plan "X", in other words a plan view towards the lock outlet 3, the arrows showing the cell wheel's direction of rotation. As can be seen from this, the different, partly symmetrical, partly asymmetric forms of the outlet cross-section can be achieved by correspondingly designed covers 3a-3f of the lock outlet 3, as these covers can either be in one piece with the lock outlet 3 or also (see figure 1 ) with the lock housing 1. The symmetrical designs corresponding to Figure 5-7 are preferably used in connection with a compressed air injection from both flange covers.
I ethvert tilfelle skal målet "a" på det frie uttakstverrsnitt i cellehjulets dreieretning, altså i rett vinkel til cellehjulsakselen 7, i"det minste på ett sted tilsvare den til rådighet stående åpning av sluseuttaket 3, mens målet "b" i høyden tilsvarer bredden av sluseinntaket 3, hhv. slusehuset 1, i den overveiende del av det åpne tverrsnitt av sluseuttaket 3, imidlertid mindre enn dettes bredde. Bestemmende for den ensartede tømming av massegodsstrømmen over tid er at bredden b endrer seg langs målet a med en forholdsmessig stor verdi. Herved avhenger av konstruksjonsparametre og driftsparametre om optimale resultater, i forhold til cellehjulets dreieretning, skal kunne oppnås med en bredde som stiger fra en minimal verdi til en maksimal verdi (sammelign figur 3-6), en først tiltagende og deretter avtagende bredde (sammenlign figur 7) eller en fra en maksimalverdi avtagende bredde (tilsvarende figur 3-6 , men i forholddertil med motsatt dreieretning av cellehjulet). In any case, the measurement "a" of the free outlet cross-section in the direction of rotation of the cell wheel, i.e. at right angles to the cell wheel shaft 7, in at least one place must correspond to the available opening of the lock outlet 3, while the measurement "b" in height corresponds to the width of the lock inlet 3, or lock housing 1, in the predominant part of the open cross-section of the lock outlet 3, however, less than its width. Determining the uniform emptying of the bulk cargo flow over time is that the width b changes along the measure a with a proportionally large value It therefore depends on construction parameters and operating parameters whether optimal results, in relation to the cell wheel's direction of rotation, should be achieved with a width that rises from a minimum value to a maximum value (compare figure 3-6), a first increasing and then decreasing width (compare figure 7) or a width decreasing from a maximum value (similar to figure 3-6, but in relation to that with the opposite direction of rotation of the cell wheel).
