(54) Korntørreapparat.(54) Grain dryer.

Opfindelsen vedrører et korntørreapparat omfattende en kornbeholder med vertikalt midterrør, hvortil der er koblet en ventilator til opnåelse af luftgennemstrømning i kornet i kornbeholderen gennem åbninger/huller i dennes væg, åbninger fordelt langs midterrørets flade, midterrørets indre og ventilatoren, hvilken ventilator er indstillelig i og ligger tættende an mod midterrøret til regulering af midterrørets gennemstrømningsområde, hvorhos ventilatoren er ophængt i et kabel, der er forbundet med et spil til løftning og sænkning af ventilatoren i midterrøret.The invention relates to a grain dryer comprising a grain container with a vertical central tube, to which a fan is connected for obtaining air flow in the grain in the grain container through openings / holes in its wall, openings distributed along the surface of the central tube, the inner tube interior and the fan abuts the center tube to regulate the flow area of the center tube, the fan being suspended in a cable connected to a winch for lifting and lowering the fan in the center tube.

Ved et kendt korntørreapparat af den ovenfor nævnte art reguleres luftgennemstrømningen i midterrøret ved hjælp af en lufttæt slange eller strømpe, som trækkes ned over midterrørets øver- 143002 2 ste del, og som går over i en flange eller et skørt, som strækker sig ud over overfladen af det korn, som befinder sig i kornbeholderen. Herved opnås, at sugeventilatoren, som er placeret i midterrørets top, ikke suger luft ind gennem de åbninger, som befinder sig i den del af centralrøret, som rager op over kornet i kornbeholderen.In a known grain dryer of the above-mentioned type, the air flow in the central tube is regulated by means of an airtight hose or sock which is pulled down over the upper part of the central tube and which passes into a flange or skirt which extends beyond the surface of the grain contained in the grain container. This ensures that the suction fan, which is located in the top of the central tube, does not suck air in through the openings which are located in the part of the central tube which projects above the grain in the grain container.

Når f.eks. kornbeholderen skal fyldes yderligere, må det nævnte skørt eller flange, som består af et fleksibelt materiale, trækkes til side og hæves sammen med den nævnte slange på midterrøret for at give plads til yderligere påfyldning af korn.When e.g. the grain container is to be further filled, said skirt or flange, which consists of a flexible material, must be pulled aside and raised together with said hose on the middle tube to make room for further filling of grain.

Ved det nævnte kendte korntørreapparat kan luftstrømmen gennem kornet ikke reguleres i forskellige niveauer, idet den luft, som suges ind gennem midterrørets åbninger nede i kornmassen, bevirker en luftgennemstrømning i hele kornmassen.With the said known grain dryer, the air flow through the grain cannot be regulated at different levels, as the air which is sucked in through the openings of the central pipe down in the grain mass causes an air flow through the whole grain mass.

Såfremt man ønsker at tilvejebringe en ekstra stærk udluftning ved hjælp af luftgennemstrømning i kornmassens nederste del, som erfaringsmæssigt ofte kan indeholde mere fugtighed end den øvre del, må åbningerne i den del af centralrøret, som befinder sig nede i kornmassen, kunne lukkes i forskellige områder, hvilket ville kræve ekstra udstyr og dermed en dyrere udformning af midterrøret .If it is desired to provide an extra strong vent by means of air flow in the lower part of the grain mass, which from experience can often contain more moisture than the upper part, it must be possible to close the openings in the part of the central pipe which is down in the grain mass. , which would require additional equipment and thus a more expensive design of the center tube.

Fra USA-patentskrift nr.2.765.542 kendes der et høtørreappa-rat, hvor gennemstrømningsområdet i midterrøret kan reguleres på en enkel og nassende måde således, at hele luftgennemstrømningen, som tilvejebringes af ventilatoren, efter valg kan koncentreres til midterrørets nederste del eller successivt kan fordeles nedefra og opefter til at omfatte hele midterrørets væg med åbninger.U.S. Pat. No. 2,765,542 discloses a hay dryer in which the flow area in the middle tube can be regulated in a simple and moist manner so that the entire air flow provided by the fan can optionally be concentrated to the lower part of the middle tube or successively distributed from the bottom up to cover the entire wall of the center tube with openings.

Dette er opnået ved, at ventilatoren er anbragt indstillelig i og ligger tættende an mod midterrøret ved hjælp af passende indretninger. Denne indstillelighed opnås ved, at ventilatoren er ophængt i et kabel, som er forbundet med et spil til løftning og sænkning af ventilatoren i midterrøret. Når der ønskes en forøgelse af luftgennemstrømningen i den nederste del af høet i beholderen, sænkes ventilatoren ned til midterrørets nederste del. Såfremt ventilatoren benyttes som sugeventilator, suges der luft gennem åbninger eller huller i beholdervæggen, gennem de nederste lag af høet og ind gennem de nederste åbninger i midterrøret til ventilatoren, som trykker luften op gennem midterrøret og ud i den omgivende luft. Såfremt ventilatoren benyttes som trykventilator, vil luftstrømmen forløbe modsat af det ovenfor nævnte strømningsfor3øb. Når de neder- 3 143002 ste lag af høet i beholderen således er tørret ved hjælp af den gennemstrømmende, kold^ omgivende luft, kan ventilatoren efterhånden trækkes opefter i midterrøret og fastgøres på ethvert ønsket sted.This is achieved by the fan being arranged adjustably in and abutting sealingly against the central pipe by means of suitable devices. This adjustability is achieved by the fan being suspended in a cable which is connected to a winch for lifting and lowering the fan in the center pipe. When an increase in the air flow in the lower part of the hay in the container is desired, the fan is lowered down to the lower part of the middle pipe. If the fan is used as a suction fan, air is sucked through openings or holes in the container wall, through the lower layers of the hay and in through the lower openings in the middle pipe to the fan, which pushes the air up through the middle pipe and into the surrounding air. If the fan is used as a pressure fan, the air flow will proceed opposite to the flow sequence mentioned above. Thus, when the lower layers of the hay in the container have been dried by means of the flowing, cold ambient air, the fan can gradually be pulled upwards in the central tube and fastened at any desired place.

Hensigten ned den foreliggende opfindelse er ved et komtørreapparat, sen virker efter sanne princip som det ovenfor omtalte høtørreapparat, at tilvejebringe en enkel og rimelig tæbiingsindretning, sern også muliggør let indstilling og eventuelt fastgørelse af ventilatoren i midterrøret, hvilket opnås ved, at ventilatorens hus er forsynet med øvre og nedre, elastiske tætningsringe med udragende tætningslaber, som samvirker med midterrørets indervæg.The object of the present invention is to provide a comb dryer, which operates according to the true principle of the hay dryer mentioned above, to provide a simple and inexpensive tapping device, which also allows easy adjustment and possible attachment of the fan in the middle tube, which is achieved by provided with upper and lower, elastic sealing rings with projecting sealing lips, which cooperate with the inner wall of the central tube.

Opfindelsen forklares nærmere i det følgende med henvisning til tegningen, hvor fig. 1 skematisk viser et komtørreapparat baseret på det i og for sig kendte princip, som er omtalt i det foregående i forbindelse med USA patentskrift nr. 2.765.542, hvilket apparat ses fra siden og delvis i snit, og fig. 2 ventilatorens tætnings- og fastgørelsesindretning i midterrøret.The invention is explained in more detail in the following with reference to the drawing, in which fig. 1 schematically shows an oven dryer apparatus based on the principle known per se, which is discussed above in connection with U.S. Pat. No. 2,765,542, which apparatus is seen from the side and partly in section, and fig. 2 the sealing and fastening device of the fan in the center pipe.

Korntørreapparatet ifølge fig. 1 består af en kornbeholder 1, fortrinsvis cylindrisk, med luftgennemtrængelige vægge samt et lodret midterrør 2, der er udstyret med et antal åbninger 3, som er fordelt om og langs midterrøret i hele dettes længde. Midterrøret 2 rager fortrinsvis noget op over kornbeholderen 1's øvre kant 1' og er forsynet med et spil 4, som kan være manuelt drevet ved hjælp af et håndsving 5. I et kabel 6, som løber nedefter fra spillet, er der ophængt en suge/trykventilator 7, som er indrettet til at hæves og sænkes i midterrøret 1, og som ved hjælp af hensigtsmæssige indretninger kan fastholdes og bringes til at ligge tætnende an mod midterrørets indre væg i ønskede stillinger.The grain dryer according to FIG. 1 consists of a grain container 1, preferably cylindrical, with air-permeable walls and a vertical central tube 2, equipped with a number of openings 3, which are distributed around and along the central tube along its entire length. The middle tube 2 preferably protrudes somewhat above the upper edge 1 'of the grain container 1 and is provided with a winch 4, which can be manually driven by means of a crank 5. In a cable 6, which runs downwards from the winch, a suction / is suspended. pressure fan 7, which is arranged to be raised and lowered in the central pipe 1, and which by means of suitable devices can be held and brought to lie sealingly against the inner wall of the central pipe in desired positions.

Den nævnte tætnings- og fastgørelsesindretning for ventilatoren 7 i midterrøret 2 omfatter ved den øvre og nedre kant af ventilatoren 7's hus 7' anbragte elastiske tætningsringe 14 og 15 af læbetypen, hvor ringen er fastgjort i selve ventilatorhuset og rager ud mod midterrøret 2's indre væg i tætnende og eventuelt gribende samvirke med denne, som det er vist i fig. 2.Said sealing and fastening device for the fan 7 in the middle tube 2 comprises at the upper and lower edge of the fan 7 housing 7 'of the lip-type sealing rings 14 and 15, the ring being fixed in the fan housing itself and projecting towards the inner wall 2 of the middle tube 2 in sealing and possibly gripping interaction with it, as shown in fig. 2.

De udragende læber af tætningsringene 14 og 15 kan være således dimensioneret, at læberne, når ventilatoren 7 sænkes nedefter i midterrøret 2, vil slæbe mod midterrørets indre væg og være vendt opad. Ved at give ventilatoren 7 en lille opadgående bevægelse ved hjælp af kablet 6 og spillet 4, vil tætningslæberne på tæt- 4 143002 ningsringene 14 og 15 blive presset til anlæg mod midterrøret 2's indre væg, hvorved luft ikke kan passere mellem midterrøret og ventilatorhuset, samtidig med at ventilatorhuset bliver liggende blødt fastspændt mod midterrøret 2, så at overføring af vibrationer fra ventilatoren til midterrøret dæmpes i væsentlig grad. Når ventilatoren indstilles ved hjælp af den nævnte sænkebevægelse og den derefter følgende lille opadgående bevægelse for at opnå den nævnte tætning, må ventilatorhuset 7' holdes på plads ved hjælp af spillet 4, som derfor er forsynet med en spærreindretning. Når ventilatorhuset 7' skal sænkes yderligere, kan dette gøres ved blot at slække kablet 6 fra spillet 4. Når ventilatorhuset 71 imidlertid skal hæves i midterrøret 2, vil de udadra-gende læber på tætningsringene 14 og 15 hindre dette. Midterrøret 2 er derfor forsynet med vulster 16, der danner indvendige spor i midterrørvæggen, hvilke spor har samme indbyrdes afstand som tætningsringene 14 og 15. Ved at bringe tætningsringene 14 og 15 på ventilatorhuset 7' ind i sporene 16, vil tætningslæberne rage frit ind i sporene, og ventilatorhuset 7' kan derved trækkes opefter uden væsentlig deformering af tætningsringene 14 og 15, som nu er vendt i modsat retning af stillingen som vist i nederste del af midterrøret 2 i fig. 2. Når ventilhuset 7' under en sådan optrækningsbevægelse skal anbringes i den ønskede position, vil læberne på tætningsringene 14 og 15 befinde sig i en sådan stilling, at de hindrer ventilatorhuset 7' at glide nedefter i midterrøret. Når derefter ventilatorhuset 7' skal sænkes nedefter i midterrøret 2, må det derfor først hæves til det første par samvirkende indre spor 16 i midterrøret, hvor læberne på tætnings-ringene 14 og 15 kan blive afspændt, hvorefter ventilatorhuset 7' kan sænkes til en ny stilling, i hvilken det fastholdes ved hjælp af spillet, såfremt læberne på tætningsringene 14 og 15 ikke atter bliver afspændt i et nedenfor liggende sporpar 16 og derefter bliver hævet opad til den ønskede stilling.The projecting lips of the sealing rings 14 and 15 can be dimensioned such that when the fan 7 is lowered downwards in the central pipe 2, the lips will drag against the inner wall of the central pipe and be turned upwards. By giving the fan 7 a slight upward movement by means of the cable 6 and the winch 4, the sealing lips on the sealing rings 14 and 15 will be pressed into abutment against the inner wall of the central pipe 2, whereby air can not pass between the central pipe and the fan housing, at the same time with the fan housing being softly clamped against the center tube 2, so that the transmission of vibrations from the fan to the center tube is substantially damped. When the fan is adjusted by means of said lowering movement and the subsequent small upward movement in order to achieve said seal, the fan housing 7 'must be held in place by means of the winch 4, which is therefore provided with a locking device. When the fan housing 7 'is to be lowered further, this can be done by simply loosening the cable 6 from the winch 4. However, when the fan housing 71 is to be raised in the central pipe 2, the outwardly projecting lips on the sealing rings 14 and 15 will prevent this. The central pipe 2 is therefore provided with beads 16 forming inner grooves in the central pipe wall, which grooves are the same distance apart as the sealing rings 14 and 15. By bringing the sealing rings 14 and 15 on the fan housing 7 'into the grooves 16, the sealing lips will protrude freely into the grooves, and the fan housing 7 'can thereby be pulled upwards without substantially deforming the sealing rings 14 and 15, which are now turned in the opposite direction of the position as shown in the lower part of the central pipe 2 in fig. When the valve housing 7 'is to be placed in the desired position during such a pull-up movement, the lips of the sealing rings 14 and 15 will be in such a position that they prevent the fan housing 7' from sliding downwards in the central pipe. Therefore, when the fan housing 7 'is to be lowered down into the central pipe 2, it must first be raised to the first pair of cooperating inner grooves 16 in the central pipe, where the lips of the sealing rings 14 and 15 can be relaxed, after which the fan housing 7' can be lowered to a new position in which it is held by means of the winch, provided that the lips of the sealing rings 14 and 15 are not again relaxed in a pair of grooves 16 below and are then raised upwards to the desired position.

Under brug af korntørreapparatet indstilles ventilatoren 7 i midterrøret 2 afhængigt af den påfyldte kornmængde 13, hvis overflade 13’ i figuren rager noget op over kornbeholderen 1's halve højde. Såfremt der ønskes en jævn gennemluftning af hele kornmængden, bringes ventilatoren 7 til en stilling lige under kornfladen 13', hvorved den omgivende luft vil strømme gennem kornbeholderen l's sidevægge, gennem kornmassen 13 og gennem åbningerne 3 i midterrøret 2, som vist ved hjælp af pile, ogWhen using the grain dryer, the fan 7 is set in the central tube 2 depending on the amount of grain filled 13, the surface 13 'of which in the figure protrudes slightly above the half height of the grain container 1. If an even aeration of the entire grain quantity is desired, the fan 7 is brought to a position just below the grain surface 13 ', whereby the ambient air will flow through the side walls of the grain container 1, through the grain mass 13 and through the openings 3 in the middle tube 2, as shown by arrows , and
