Description

Uppfinnare: B Omar och H Oetiker Prioritet begard frdn den 12 april 1961 (Schweiz) For att tomma siloceller pa pulver- till grynformigt ras- eller skakgods ha .olika anordningar foreslagits, medelst vilka en likartad och likformig tomning utan nagon bryggbildning kan astadkommas. Dessa arbeta foretra.- desvis pa mekanisk eller pneumatisk vag. Inventors: B Omar and H Oetiker Priority requested from 12 April 1961 (Switzerland) In order to empty silo cells on powdered to granular or shaky goods, different devices have been proposed, by means of which a similar and uniform emptying without any bridge formation can be achieved. These work preferably on mechanical or pneumatic roads.

Alla dessa kanda anordningar uppvisa emellertid nackdelar. Vid de mekaniska anordningarna uppstar salunda framfor alit vidhaftning av rasgodset, icke onskad utstromning ,samt en diskontinuerlig tiimning. Vid de pneumatiska anordningarna hesta nackdelarna av en okontrollerad tomning och nedskjutning av rasgodset, vilket kan leda till bildning av haligheter I detta Over tomningsstallet, vilket medfOr sonderdelning av rasgodset. However, all of these known devices have disadvantages. In the case of the mechanical devices, there is thus above all adhesion of the race goods, unwanted outflow, and a discontinuous emptying. In the case of the pneumatic devices, the disadvantages of an uncontrolled emptying and shooting down of the cargo are the same, which can lead to the formation of cavities in this over-emptying stable, which entails probe division of the cargo.

Andamalet med den i det Mande beskrivna uppfinningen bestft i att astadkomma en forballx-ad anordning, medelst vilken tomningen av siloceller pa pulver- till grynformigt rasgods kan ske 'efter ett faststallt program, som bygger pa principen att godset fluidiseras medelst luft eller andra lampliga gaser pa ett dammfritt salt utan bryggbildning och hopklumpningar till minimala kostnader, samtidigt som en hog godskvalitet och godtycklig, konstant blandbarhet erhalles. SamIldigt skola de ovannamnda nackdelarna kringgas genom indelning av cellerna i separata falt och genom anpassning av tiimningsanordningen efter den lampliga lutningsvinkeln for ifragavarande gods och genom anordnandet av en lutande insats, vilken eventuellt ãr utformad sasom ,ett tak, Over tomningsanordningen. The object of the invention described in Mande is to provide a prefabricated device, by means of which the emptying of silo cells on powdered to granular bulk goods can take place according to an established program, which is based on the principle that the goods are fluidized by air or other suitable gases. on a dust-free salt without bridging and clumping at minimal costs, while maintaining a high quality of goods and arbitrary, constant miscibility. At the same time, the above-mentioned disadvantages should be circumvented by dividing the cells into separate fields and by adapting the tilting device according to the appropriate angle of inclination of the goods in question and by arranging a sloping insert, which may be designed as a roof, over the emptying device.

Uppfinningen avser en anordning for tamning av celler med pulver- till grynformigt rasgods Over ett lutande cellgolv Iran en langstrackt samlingstomningskammare. Uppfinningen kannetecknas darvid i huvudsak darav, att den i forhallande till samlingstomningskanimaren angransande nedre delen av cell golvet Or overtackt av en lutande insats under bildning av en tomningsspalt och medelst porosa element och luftningskammare under insatsen uppdelad i separata luftningsfalt utefter tomningsspalten, varvid tomningsspalten Or anordnad vid spetsen av en genom cellgolvet och den lutande insatsen bildad nedatrik tad V-formad tratt. The invention relates to a device for taming cells with powdered to granular bulk material. Over an inclined cell floor, an elongated collection emptying chamber. The invention can be characterized mainly in that the lower part of the cell floor Or adjacent to the collection emptying conveyor is covered by a sloping insert during the formation of an emptying gap and by means of porous elements and aeration chamber below the insert divided into separate aeration folds along the emptying gap. the tip of a downwardly oriented V-shaped funnel formed by the cell floor and the inclined insert.

Uppfinningen kan vidareutbildas p0 sadant satt, att cellgolvet gores installbart. Mimed kan uttomningsstrackan anpassas efter den lampliga lutningsvinkeln for olika rasgods. The invention can be further trained in such a way that the cell floor is made installable. With this, the emptying distance can be adapted to the suitable angle of inclination for different breeds.

Man kan Oven anvanda en takformad, den nedre delen av cellgolvet i narheten av samlingskanalen overtackande insats, varvid ingen. okontrollerad tiimning av gods -sker i samlingskanalen. One can also use a roof-shaped, the lower part of the cell floor in the vicinity of the collecting duct overhanging insert, whereby none. uncontrolled emptying of goods takes place in the collection channel.

Genom att anordna porosa element i cellgolvet och i insatsen astadkommes mot luftningen svarande samtidigt lagda cellgolv- och insatsfalt, varvid man vid utarbetande av tomningsprogrammet kan taga hansyn till och utan svarighet anpassa dessa efter olika forhallanden sasom blandning, siloniva, sjunkningstendens osv. By arranging porous elements in the cell floor and in the insert, similarly laid cell floor and insert folds are created against the aeration, whereby in preparing the emptying program one can take into account and without responsibility adapt them to different conditions such as mixing, siloniva, sinking tendency, etc.

For att genomfora tonaningsprogrammet anvandas ventiler eventuellt strvosystem, varvid ventilerna genom ett speciellt enkelt och driftsakert byggn'adssatt gaits ett nytt utf0- rande. In order to carry out the toning program, valves or strut systems are used, whereby the valves have been given a new design through a particularly simple and reliable construction.

Dirjamte anvandas perforerade ror for luftning av luftforclelningslador, varigenom en latt installhar doserbarhet mojliggores. Directly perforated tubes are used for aeration of air separation barns, thus enabling easy installation and dosing.

For att forstora cellerna anvandes lampligen ,ett Hertal varandra kompletterande takformade insatser med lampligt uppdelade tomningsf all, varvid genom ett ytterligare, speciellt tomningsprogram astadkomnies en lamplig tömning av cellerna. In order to enlarge the cells, a number of complementary roof-shaped inserts with aptly divided emptying cases were used, whereby a further, special emptying program achieves a suitable emptying of the cells.

Det Or dessutom viktigt att luftkuddar bildas och uppratthallas mellan .samlingskana- 2— 137 320 — len och den takformade insatsen, vilka luftkuddar a ena sidan tjana till stoftavskiljning, varigenom den genom avluftningskanalen fran kuddarna i den ovre delen av cellen avgaende luften i huvudsak dr Fri Fran damm, och a andra sidan astadkommes en hela ti-den kontrollerad, fluidiserad tomning utan nagon risk for tilltappning. It is also important that air cushions are formed and maintained between the collection duct and the roof-shaped insert, which air cushions on the one hand serve for dust separation, whereby the air emanating from the cushions in the upper part of the cell mainly through the vent duct Free from dust, and on the other hand a constantly controlled, fluidized emptying is achieved without any risk of draining.

Saval samlingskanalen 16 som de porosa elementen 18 aro overtackta av en utefter cellens 10 hela langd anordnad, lutande insats 20, vilken dr utford sa., att en langstrackt oppning eller slits 21 bildas mellan insatsen 20 och cellgolvet 13. Luftningskammaren 19 ar utefter slit sen 21 indelad separata luftningsfalt genom lufttatt anbragta platar 22. Luftningsfalten kunna fyllas Hied luft eller andra lampliga gaser genom separata, valfritt paverkbara ventiler 25 vid en gemensam tillfOrsel- eller matarledning 24. The rope adjacent to the collecting duct 16 lying at the lower part of the inclined cell floor 13 is provided with porous elements 18 above the aeration can chamber 19. The collecting duct 16 as the porous elements 18 are covered by a sloping insert 20 arranged along the entire length of the cell 10, which dr challenge said that an elongated opening or slit 21 is formed between the insert 20 and the cell floor 13. The aeration chamber 19 is divided along the slit after 21 by separate aeration folds through aerated plates 22. The aeration pads can be filled. 25 at a common supply or supply line 24.

Det under den lutande insatsen 20 bildade utrymmet 27 fir genom en avluftningsledning 28 forbundet med en stoftavskilj are 29. The space 27 formed under the inclined insert 20 is connected by a vent line 28 to a dust separator 29.

Samlingskanalen 16 kan vara utford pa hint sfitt. Vid foreligganole forsta utforingsform aro por8sa element 30 anordnade Over en genom ett luftningssystem 21 med luft fOrsedd kammare 32. Sannlingskanalen 16 dr fOrsedd med ett nivakanselelement 33, som be-star av ett membran 34 och en stromstallare 35 i ett hus 36. The collection channel 16 can be a challenge on the other side. In the present first embodiment, porous elements 30 are arranged over a chamber 32 provided with an aeration system 21. The truth channel 16 is provided with a level cantilever element 33, which consists of a diaphragm 34 and a current generator 35 in a housing 36.

Anordningen har foljande funktionssatt. Genom den stallcla fordringen, namligen att rasgodset 9 icke okontrollerat far uttommas samlingskanalen 16, dr det lutande golvet med de porosa elementen 18 pa sadant satt Overtackta av en lutande insats 20, och lutningen av golvet 13, 'storleken av slitsen 21 och insatsens 20 tackning av de porosa elementen 18 samt golvets 13 lutningsvinkel avpassad forhallande fill rasgodsets 9 rasvinkel, att detta lake framtranger till samlingskanalen 16. Genom luftning av ett av falten i luftningskammaren och genom att brings denna luftstrom eller nagon annan lamplig gas att stromma genom de porosa elementen 18 astadkommes en fluidisering av rasgodset Over, ifragavarande fah, varigenom della gods ilksom en vatskestrom utflyter i samlingskanalen 16. Darvid utvaljes del fan, som shall avluftas, genom installbara ventiler 25, vilka arc inkopplade mellan en tillforselledning 24 och de separata falten 1 luftningskammaren 19. The device has the following function. Due to the stable requirement, namely that the bulk material 9 is not emptied uncontrollably, the collecting channel 16, where the sloping floor with the porous elements 18 is thus covered by a sloping insert 20, and the inclination of the floor 13, the size of the slot 21 and the filling of the insert 20 of the porous elements 18 and the angle of inclination of the floor 13 adapted to the angle of inclination of the bulk material 9, that this lake protrudes to the collecting channel 16. By aerating one of the folds in the aeration chamber and by causing this air stream or some other suitable gas to flow through the porous elements 18 A fluidisation of the bulk material Over, in question, is effected, whereby part of the material as a liquid stream flows out into the collecting channel 16. In this case part of the fan, which is to be vented, is selected through installable valves 25, which arc are connected between a supply line 24 and the separate folds 1.

Genom att samlingskanalen 16 dr utbildad lutande dr det majligt att astadkomma ytterligare transport av rasgodset enligt fluidiseringsprincipen Over de porosa elementen 18 till en upptagningsstation, exernpelvis en sluss. Darvid fir ett nivakfinselelement 33 tillordnat samlingskanalen, vilket element tjanar for styrning av fluidiseringen av det for tomning avsedda godset, och vilket element Oven astadkommer och bibehaller en luftkudde 1 utrymmet 27. Luftkudden utbildas i utrymmet 27 genom att fluldiseringsgaserna samlas darstades. Darigenom undvikes tilltappning av uttomningsanordningen, vilket a.ven medfOr en likformig utstromning av ett gods av 'Ogre kvalitet. Genom den valcla uppdelningen av cellens totala langd i separata fall kan man anordna luftningen 1 enlighet med ett lampligt program, vilket skall narmare klargoras i samband med beskrivningen av en annan sasom lamplig befunnen utforingsform, varvid en godtycklig men hela tiden kontrollerad blandbarhet °ch nedsjunkningsfOrmaga hos godset medgives. Due to the fact that the collecting channel 16 is formed inclined, it is possible to provide further transport of the bulk goods according to the fluidization principle over the porous elements 18 to a receiving station, for example a lock. Thereby, a level fin element 33 is assigned to the collecting duct, which element serves to control the fluidization of the goods intended for emptying, and which element also provides and maintains an air cushion in the space 27. The air cushion is formed in the space 27 by collecting the fluidizing gases there. This avoids draining of the emptying device, which also leads to a uniform outflow of a goods of 'Ogre quality. Due to the optional division of the total length of the cell in separate cases, the aeration can be arranged in accordance with a suitable program, which will be further elucidated in connection with the description of another embodiment found suitable as suitable, whereby an arbitrary but constantly controlled miscibility and immersion capacity of the goods are allowed.

Den hela tiden forekommande luftkudden — utrymmet 27 tjanar sasom en forsta stoftavskiljare for fluidiseringsgasen. Detta utrymme star vidare genom en avluftningsledning 28 i forbindelse med en stoftavskilj are 29 och darifran med ytterluften. The constantly occurring air cushion space 27 serves as a first dust separator for the fluidizing gas. This space is further through a vent line 28 in connection with a dust separator 29 and thence with the outside air.

Vid vidareutbildning av uppfinningstanken kan det synas onskvart att omvaxlande kunna anvanda cellerna few rasgods med olika rasvinklar. For detta kraves en varierad utforingsform, vid vilken fOrekommer ett diminstone i nedre delen installbart cellgolv, varvid aven sl'itsbredden 21 dr installbar. In further training of the inventive concept, it may seem inconvenient to be able to alternately use the cells few race goods with different race angles. This requires a varied embodiment, in which there is a diminstone in the lower part installable cell floor, whereby also the slot width 21 dr installable.

I fig. 2 visas en anordning som uppfyller detta krav. Rasgodset 9 befinner sig fartfarande i en av vaggar 11 med tak 12 och golv 13 utbildad cell, vilken pdfylles medelst en tillfarselanordning 17. En omkring en lag-ring 38 vridbar nederdel av cellgolvet, vilken: kan avluftas genom en tillforselledning 24 Over reglerbara ventiler 25 och en ,elastisk rordel 39 samt luftningskammaren 19 med porosa element 18, kan installas till sin lutning. Darvid dr slitsen 21 instalbar i forhallande till den lutande insatsen 20 i den utstrackning, som visas medelst punktstreckade linjer, varigenom den kan anpassas efter olika rasgods rasvinkla:r. Den -vidare tomningen sker medelst flUidisering i samlingskanalen 16 pa ovan beskrivet satt medelst de prom .elementen 30 Over kammaren 32 och luftningssystemet 31 och kontrolleras genom ett nivakanselelement 33. Den hela tiden i utrymmet 27 forhandenvarande luftkudden star medelst en avtuftningsledning 28 i forbindelse med cellens ovre utrymme 40, vilket i fOreliggande fall tjanar sasom en andra stoftavskilj are efter stoftavskiljningen i utrymmet 27. Anordningens funktion forbattras genom en aspirator med en valfritt inkopplingsbar ledning 26 fran utrymmet 27. Fig. 2 shows a device which meets this requirement. The cargo 9 is still located in a cell formed by cradles 11 with roof 12 and floor 13, which is filled by means of a supply device 17. A lower part of the cell floor rotatable about a bearing 38, which: can be vented through a supply line 24 via adjustable valves 25 and one, elastic rudder part 39 and the aeration chamber 19 with porous elements 18, can be installed to its inclination. Thereby, the slot 21 is adjustable in relation to the inclined insert 20 to the extent shown by dotted lines, whereby it can be adapted to different race angles. The further emptying takes place by means of fluidization in the collecting duct 16 in the manner described above by means of the prom elements 25 above the chamber 32 and the aeration system 31 and is controlled by a level cantilever element 33. The air cushion constantly present in the space 27 stands by means of a defrost line 28 in connection with the cell. upper space 40, which in the present case serves as a second dust separator after the dust separation in the space 27. The function of the device is improved by an aspirator with an optionally connectable line 26 from the space 27.

Funktionssattet motsvarar den ovan beskrivna anordningen enligt fig. 1, men uppvisar den namnda viktiga fordelen att fludiseringsanordningen kan anpassas efter rasgodsets rasvinkel samt att mojlighet ges att inkoppla en aspirator. The mode of operation corresponds to the device described above according to Fig. 1, but has the mentioned important advantage that the fluidization device can be adapted to the race angle of the race material and that it is possible to connect an aspirator.

By joining two cells in accordance with Fig. 1 or 2, an expansion of the inventive idea is achieved, in that the cells can be built up symmetrically around the collecting channel 16, which in addition can be formed at the edge as an inclined fluidization channel. This construction set has proved to be extremely valuable and should therefore serve as described in the description of further details in the device. In this case, however, the above-described mode of operation is not significantly deviated from Iran, but only further improvements for increasing the efficiency and for simplifying the emptying of the cargo cells in question will be described. 11 and two sloping floors 13 on either side of a collection channel 16, the cell floor being at least V-shaped. The sloping floors are divided along the entire longitudinal and bi-directional direction of the cell by plates 22, which are ventilated arranged in the chambers in separate sections 101-420 (Fig. 6) which are again covered by porous elements 18 towards the inside of the cells. The inserts, which in Figs. 1 and 2 are denoted by 20 aro facing each other so that they cover the lower part of the chambers 19, i.e. the folds 102, 104, 106, 108, 110, 112, 114, 116, 118, 120 in accordance with Fig. 6 and intermediate collecting duct 16. This is inclined and provided with porous elements 30 (Fig. 3), to which gases can be supplied through an aeration system 31 Above the chamber 32, and it feeds a lock 41 (Fig. 4 ). Salunda forms a V-shaped insert 42 with upwardly directed tip. By arranging intermediate plates 22 in the insert chambers 43 and by providing covering by means of porous elements 44, a division of the V-shaped insert 42 is achieved in separate cases, as shown by the fields 124, 126, 128, 130, 134, 136, 138 and 140 in Fig. 6. In the top of the insert 42 is arranged a tip tacking element 45. The V-shaped insert 42 is formed in guides 46, which emanate from beams 47.

Far -Winning of the cell in accordance with a specific program Or a collection control, arranged, the principle structure of which is shown in Fig. 6. An aeration pump 60 feeds over the main valve 51 the supply line 24 and over controllable valves 25 the separate folds in the cell 10, the aeration of The folding takes place over the pipe system 48, 49 and 50 clearly shown in Figs. 3 and 4. In order to avoid tapping in the collecting duct 16, regulation is carried out by means of the level pulpit element 33, in that this element 33 is connected over a pair of pipes 62. with a control device 63 and an operating device 64, the main valve 51 is controlled by an operating line 65. In order to carry out a special emptying program, a selective control device 66 is provided, which over the control lines 67 controls the valves 25. This control can be done by means of a pressure medium. the aeration pump 60 is connected to the control device 64 and the selective control device 66. compressed air line 69. The mode of action of the device constructed according to Figs. 3, 4, 5 and 6 is, as briefly defined above and as stated in the preamble, that the view can be taken into account of different mixing requirements and decreasing tendencies of the cargo cell. The following description is limited to a hair cell shown in Fig. 6, but the principle is applicable to a cell such as that shown in part in Fig. 4, i.e. ride a cell flied two sloping collection channels 16 on each side cm a lock 41.

Rasgodset 9 befinner sig i en cell 10, 'som be-star av cellvaggar 11, luftningskammare 19 med platar 22 for uppdelning i separata golvfalt 101-120 och dfirOver anordnade porosa element 18. Den V-formade insatsen 42 over-tacker de nedre delarna av den lutande cellgolvhalvan 13 och den dfiremellan liggande samlingskanalen 16 medelst de por6sa plattorna 30 over kammaren 32. Darvid glider rasgodset 9 beroende pa storleken av cellgolvets 13 lutning, bredden av den langstrackta slitsen 21 och ifragavarande rasgods rasvinkel ut en. viss stracka i riktning mot samlingskanalen 16, vilken kanal det emellertid icke uppnar, sasom visas pa vfinstra halvan av fig. 3. For thinning av rasgodset 9 lutas nu valfritt .ett celifdlt, vilket omfattas av tre overensstimmande fait hos luftningskamrarna 19 och 43 i ena hälften av cellgolvet och ena hdlften av den V-formade insatsen 42, exempelvis fatten 101, 102 och 122. Samtidigt sker given luftning av de porosa elementen 30 i samlingskanalen 16. Darvid uppstar en fluidisering av rasgodset, varvid detta sasom en vatska avrinner genom slussen 41, sasom dr visat pa hogra sidan i fig. 3. For att majliggora dosering av luftningsmangden i go-vets 13 bagge falt kan det perforerade roret 48 i det nedre fattet 102 delvis frilaggas genom ett andra ror 49, som leder in i faltet 101. Fluidiseringsluften samlar sig clarpa ovanfar kanalen 16 och under den V-formade insatsen 42 i utrymm.et 27, dar en forsta .stoftavskiljning sker, varpa luften bortledes genom luftningsledningen 28 till det avre cellutrymmet 40, dar en. slutlig stoftavskiljning dr majlig. The cargo 9 is located in a cell 10, which consists of cell walls 11, aeration chamber 19 with plates 22 for division into separate floor folds 101-120 and porous elements 18 arranged above it. The V-shaped insert 42 overcomes the lower parts of the sloping cell floor half 13 and the intermediate collecting duct 16 by means of the porous plates 30 over the chamber 32. In this case the cargo 9 slides depending on the size of the slope of the cell floor 13, the width of the elongated slot 21 and the cargo angle of the cargo in question. a certain distance in the direction of the collecting duct 16, which duct it does not reach, however, as shown in the left half of Fig. 3. For thinning of the bulk material 9, a celifdlt is now optionally inclined, which is comprised of three corresponding faults of the aeration chambers 19 and 43 in one half of the cell floor and one half of the V-shaped insert 42, for example the barrels 101, 102 and 122. At the same time a given aeration of the porous elements 30 in the collecting channel 16. A fluidisation of the bulk material occurs, whereby this, like a liquid, drains through the lock 41, as shown on the right-hand side in Fig. 3. In order to allow dosing of the amount of aeration in the rear field of the go-13, the perforated tube 48 in the lower barrel 102 can be partially exposed through a second tube 49, which leads into the field 101. The fluidizing air collects clearly above the duct 16 and below the V-shaped insert 42 in the space 27, where a first dust separation takes place, whereupon the air is diverted through the aeration line 28 to the outlet. e cell space 40, where one. final dust separation dr majlig.

Om mera rasgods utstrommar ur cellen genom slitsen 21 i samlingskanalen 16 an som kan bortforas av slussen 41, sa tryckes membranet 34 i nivakanselelementet genom trycket air (let sig daraver befintliga rasgodset utat, varvid kopplingsanordningen 35 paverkas, sa att huvudventilen 51 slutes Over de bfigge ledningarna 62, regleranordningen 63, manoveranordningen 64 och manoverledningen 65, och luftningen av cellgolvet 13 och den V-formade insatsen 42 avbrytes och strommen av rasgods avtar. Darigenom kan samlingskanalen tommas genom slussen 41 utan flagon efterstromning av rasgods frail cellen 10, till class att kopplingsanordningen 35 i nivakanselelementet 33 'ger oppnas, varpa luftningen av fallen 101, 102 och 122 Ater paborj as. If more cargo flows out of the cell through the slot 21 in the collection channel 16 which can be removed by the lock 41, then the diaphragm 34 in the level pulpit element is pushed by the air pressure (let the existing cargo out), whereby the coupling device 35 is actuated so that the main valve 51 closes. the conduits 62, the control device 63, the control device 64 and the control line 65, and the aeration of the cell floor 13 and the V-shaped insert 42 is interrupted and the flow of cargo decreases, thereby the collection channel can be emptied through the lock 41 without flake afterflow of cargo frail cell 10, to class the coupling device 35 in the level cantilever element 33 'is opened, warping the aeration of the cases 101, 102 and 122 is reopened.

For att uppna bestamda blandningar av eller hopsjunkningstendenser hos rasgodset kan ett sorskilt tomningsprogram med anvandning av selektiv reglering medelst anordningen 66 ifragakomma. Derma selektiva reglering mojliggor en till vissa tider begransad luftning av en motsvarande faltkombination oar. en .exempelvis cyklisk turordning mellan de faltkombinationer, som skola luftas. Exempelvis foljer darvid kombinationen 101, 102, 123 pa kombinationen 103, 104 och 124 osv. till 119, 120, 140 eller med nagon annan Onskad ordningsfoljd. Darvid tillfores exempelvis tryckluft Iran luftningspumpen 60 genom tryekluftledningen 69 Over man5veranordningen 61 och den selektiva regleranordningen till ventilmanoverledningarna 67 och genom dessa till ventilerna 25. Alla ventiler 25 hos de ffiltkombinationer, som icke muss, tillforas darvid tryckluft, under det att trycklufttillfiirseln till den. ventil, som avluftas, är avstangd. Darvid arbetar endast ventilen. 25 i fig. 5 pa sadant salt, att 00. ventilen Or sluten luften at hada hall kan genomstromma forbrukningsledningen 55 till folj ande ventil, under det att aa ventilen Or oppen luften strommar till faltkombinationens forbrukningsledning 55. Dessutom uppvisar regleringen det speciella kannetecknet, att alltid da nivakanselelementet 33 tages i ansprak, star den selektiva regleringsanordningens 66 tidgivningsanordning stilla, sa att alltid den onskade effektiva luftningstiden inverkar pa ifeagavarande faltkombination, varigenom det anskade programmet folks. Eftersom luftningspumpen 60 kan anvandas bade for lull-fling och far att styra forloppet, aro tva skilda pumpsystem anordnade, varvid f5r luftningen anvandes en lagtiycksdel och for styrningen en hogtrycksdel. Del fir aven mojligt att ansluta ledningen far luftning av samlingskanalen 16 till luftningspumpen 60, vilket awn som regel sker I praktiken, ,ehuru det joke visas pa ritningarna. In order to achieve definite mixtures of or shrinking tendencies of the breed goods, a separate emptying program using selective control by means of the device 66 can be considered. This selective regulation enables a sometimes limited aeration of a corresponding field combination oar. for example, a cyclic sequence between the field combinations to be aerated. For example, the combination 101, 102, 123 then follows the combination 103, 104 and 124 and so on. to 119, 120, 140 or with any other Desired order. In this case, for example, compressed air is supplied to the aeration pump 60 through the compressed air line 69 via the control device 61 and the selective control device to the valve control lines 67 and through these to the valves 25. All valves 25 of the felt combinations, which do not have to, are supplied with compressed air. valve, which is vented, is switched off. Only the valve works. In Fig. 5 on such a salt that the valve Or closed air to have a hall can flow through the consumption line 55 to the next valve, while the valve Or the open air flows to the field line 55's consumption line 55. In addition, the control has the special characteristic that whenever the level sensor element 33 is used, the timing device of the selective control device 66 stands still, so that always the desired effective aeration time affects the field combination in question, whereby the desired program is filled. Since the aeration pump 60 can be used both for lull-fling and to control the process, two different pump systems are provided, a low-pressure part being used for the aeration and a high-pressure part for the control. It is also possible to connect the line for aeration of the collecting duct 16 to the aeration pump 60, which usually takes place in practice, although the joke is shown in the drawings.

Sasom visas av erfarenheten Or det forutom uppdelningen. air luftningskamrarna 19 och 43 medelst platarna 22 joke nadvandigt med — — flagon ytterligare indelning av de namnda, separata fatten, eftersom genom plitarna upp- star en skarp avgransning av de separata som skall luftas .och ingen lackning Lipp-star i den langstrackta slitsens 21 bagge riktningar. Ej heller paverkas de intill s.anilingskan.alen 16 liggande Om nagra separata falt i cellen aro fullkomligt tomda, sa foljer utan avbrott i tomningsprogrammet genom nivakfinselelementet 33 en snabb vaxling till pafoljande hilt. Darigenom uppstar en ekonamisk utnyttjning av anordningen. As shown by experience Or it in addition to the division. the air vent chambers 19 and 43 by means of the plates 22 jokingly with - - flake further division of the said, separate barrels, since through the plates a sharp demarcation of the separates to be vented arises and no varnishing Lipp-star in the elongate slot 21 ram directions. Nor are the ones lying next to the sanitation channel 16 affected. If some separate fields in the cell are completely empty, then a rapid change to the following hilt follows without interruption in the emptying program 33 through the level fin element 33. This results in an economical utilization of the device.

Sasom schematiskt visas i fig. 7 kan uppfinningstanken vidareutvecklas ph sadant salt, att flera V-formade insatser anvandes, sarskill vid storre celler. Darvid tacker en forsta V-formad insats 42 liksom tidigare samlingskanalen 16 och nederdelen av den genom luftningskammaren 19 och de parosa elementen 18 bildade luftningshara cellgolven 13 ph hada sidor om samlingskanalen 16. Over den aven i detta fall astad.komna slitsen mellan de porosa elementen 18 och. 44 are ytterligare V-formade insatser 42' med nya slitsar 41' anordnade mellan de poro.sa elementen 44' hos de ytterligare insatserna 42' och de porosa elementen 18 och 44, varvid insetsernas antal avpa.ssas efter cellstorleken. As schematically shown in Fig. 7, the inventive concept can be further developed ph such salt that several V-shaped inserts are used, especially in larger cells. In this case, a first V-shaped insert 42, like the previous collecting duct 16 and the lower part of the aeration-hard cell floor 13 formed by the venting chamber 19 and the porous elements 18, has sides of the collecting duct 16. Above the slot between the porous elements also provided in this case 18 and. 44 are further V-shaped inserts 42 'with new slots 41' arranged between the porous elements 44 'of the further inserts 42' and the porous elements 18 and 44, the number of inserts being adjusted according to the cell size.

Luftningskamrarna 19, 43 och 43' Oro ben i detta fall indelade i separata halt genom platar 22, vilka ffilt over ledningarna 48, 49, 50, 48', 49', 50' och 50" aro samma.nkopplade till separata faltkombinationer. Dessutom ar cellgolvets 13 luftningskammare 19 genom platar 70 uppd.elade i separata delkammare, vilkas antal beror ph de tillkommande, V-formade insatserna 42'. Luftningssystemet erhaller darigenom aven en uppdelning. Genom en matarledning 24 maths de reglerbara yentilerna 25 och 25' och fran dessa valfritt genom ventilen 25, ledningarna och riiren 48, 49, 50 oeh 50', eller ledningarna och roren 48', 49', 50" genom ventilen 25'. The vent chambers 19, 43 and 43 'are in this case divided into separate contents by plates 22, which are connected over the conduits 48, 49, 50, 48', 49 ', 50' and 50 "and are connected to separate field combinations. In addition. The aeration chamber 19 of the cell floor 13 is divided by plates 70 into separate sub-chambers, the number of which depends on the additional, V-shaped inserts 42 '. The aeration system thereby also receives a division. Through a supply line 24 the adjustable yents 25 and 25' are fed and from these optionally through the valve 25, the conduits and pipes 48, 49, 50 and 50 ', or the conduits and pipes 48', 49 ', 50 "through the valve 25'.

Darigenom luftas emellertid genom roren 48 och 49 endast de genom platarna 70 atskilda nedre delkamrarna, under det att roren 48' och 49' samt de ovre liksom de nedre delkamrarna, dvs. hela cellgolvet, fortfarande behova luftas. In this way, however, only the lower sub-chambers separated by the plates 70 are vented through the tubes 48 and 49, while the tubes 48 'and 49' and the upper as well as the lower sub-chambers, i.e. the entire cell floor, still need to be aerated.

Anordningens funktionssitt motsvarar i hu- vudsak den ovan beskrivna. Genom det storre antalet fält i cellgolvet 13 och i de V-formade insatserna 42 och 42' är det aven 116:Ivan- digt med ett stone antal ventiler .25 .och 25'. Darigenam erhaller den selektiva regleranordningen starre regleringsmojligheter, vilket emellertid joke erfordrar nagon andring av sj diva principen. The functional position of the device essentially corresponds to that described above. Due to the large number of fields in the cell floor 13 and in the V-shaped inserts 42 and 42 ', it is also 116: Usually with a stone number of valves .25 .and 25'. Darigenam obtains the selective control device rigid control possibilities, which, however, joke requires some change of the seven principle.

For att taga hansyn till bestamda utrymmeskrav osv. ar det tankbart att utbilda cel- len pa det sfitt, .som visas i fig. 8. Genom det asymmetriska anardnandet av samlingskanalerna 16 i cellgolvet 13 kunna aven de i sig sjalva symmetriska, V-farmade insatserna 42 och 42' anordnas asymmetriskt. To take into account certain space requirements, etc. It is conceivable to form the cell on the fabric shown in Fig. 8. By the asymmetrical arrangement of the collecting channels 16 in the cell floor 13, the symmetrical, V-shaped inserts 42 and 42 'themselves can also be arranged asymmetrically.

De beskrivna fyra utforingsformerna kunna pa godtyckligt salt varieras genom anvandning .av ensidigt lutande eller V-formade, luflade .eller joke luftade, symmetriskt eller asymmetriskt anordnade insatser i seller med langsghende samlingsutlopp eller samlingskanaler utan att principen far anordningen IrOn- gits. The described four embodiments can be varied on arbitrary salt by using unilaterally inclined or V-shaped, vented, or joke vented, symmetrically or asymmetrically arranged inserts in cells with longitudinal collection outlets or collection channels without the principle of the device being IrOngit.

I enlighet med fig. 9 kan uppfinningen vidareutvecklas pa sit salt, aft hela tomningsanordningen anpas.sas efter rasvinkeln for det i silon befintliga godset ph hada sid.or om och Over samlings.kanalen 16 genom en till sin lutning, i hajdled och/eller till sin tackningsbredd installbar, V-formad insats 72. In accordance with Fig. 9, the invention can be further developed on its salt, since the whole emptying device is adapted to the angle of inclination of the goods present in the silo ph had sides of and over the collecting channel 16 through a to its inclination, in height and / or to its fill width installable, V-shaped insert 72.

Over det av luftningskamrarna 19 med pittarna 22 och de porosa ,elementen 18 bildade cellgolvet 13 och de i detta for luftning.eri anordnade perforerade I-Oren 48 samt de pa des.sa teleskopiskt forskjutbara Toren 49 ar en ph ovan beskrivet salt stallbar, V-formad insats 72 anordnad. De porosa .elementen 70 aro medelst lager 75 ledat anbragt vid en styrmuff 73, som fir forskjutbart och fastklamhart anordnad pa en styrskena 74 med under elementen anordnade platar 22 och luftningskammare 77. For forandring av tackningshredden aro de porosa elementen 76 forsedda med ytterligare stallbara element 78 Over luftningskamrarna 79 med platarna 22'.
