Ingeniørfirmaet Lehmann & Ree.__ (54) Apparat til tørring af fibre og garner.Lehmann & Ree Engineering Company. (54) Apparatus for drying fibers and yarns.
Opfindelsen angår et apparat til tørring af fibre og garner med en damp-gasblanding.The invention relates to an apparatus for drying fibers and yarns with a vapor-gas mixture.
Pra tysk fremlæggelsesskrift nr. 1.935.6o5 kendes et apparat til tørring af fibre og garner, hvilket apparat omfatter en behandlingskedel, der er tilsluttet et kredsløb med en blæser, en opvarmer og et befugtningsapparat, samt yderligere et kredsløb med et evakueringsapparat og en foran dette indskudt kondensator. Ved dette kendte apparat behandles det i behandlingskedlen anbragte tørringsgods ned en danp-gasblanding, som ved hjælp af blæseren cirkuleres i det dertil sluttede kredsløb og opvarmes i opvarmeren og befugtes i be-fugtningsapparatet. Når der er opnået en fastsat temperaturforskel mellem opvarmningsgassen og afgangsgassens temperatur, indkobles UU19 2 evakueringsapparatet og hele kredsløbet udpumpes. Ved opnåelsen af det fastsatte vakuum frakobles evakueringsapparatet og kredsløbet fyldes med frisk gas, f.eks. luft fra omgivelserne. Derpå pumpes kredsløbet atter op til et fastsat overtryk, hvorpå opvarmningspro-cessen gentages. Dette apparat er behæftet med den ulempe, at kapaciteten af de dyre apparater til tilvejebringelse og opretholdelse af tørrebetingelserne, nemlig befugtningsapparatet, blæseren, opvarmeren, evakueringsapparatet med kondensatoren samt trykkilden til oppumpning af kredsløbet ikke udnyttes fuldt ud, men i stedet arbejder diskontinuert med mellemliggende stilstandsperioder. Dette medfører, at apparatets fremstillingsomkostninger bliver høje i forhold til dets tørrekapacitet,og at apparatets arbejdsmåde er uhensigtsmæssig og uøkonomisk.German German Patent Specification No. 1,935.6o5 discloses an apparatus for drying fibers and yarns, which apparatus comprises a treatment boiler connected to a circuit with a blower, a heater and a humidifier, and a further circuit with an evacuation apparatus and a prior one. inserted capacitor. In this known apparatus, the drying material placed in the treatment boiler is treated with a steam gas mixture which is circulated by means of the fan in the connected circuit and heated in the heater and wetted in the humidifier. When a fixed temperature difference has been obtained between the heating gas and the exhaust gas temperature, the UU19 2 evacuation device is switched on and the entire circuit is pumped out. Upon reaching the set vacuum, the evacuation device is disconnected and the circuit is filled with fresh gas, e.g. air from the surroundings. Then the circuit is pumped back up to a set overpressure and the heating process is repeated. This apparatus suffers from the disadvantage that the capacity of the expensive apparatus for providing and maintaining the drying conditions, namely, the humidifier, the fan, the heater, the evacuation apparatus with the capacitor and the pressure source for pumping the circuit are not fully utilized, but instead operate intermittently with intermediate periods of time. . This means that the cost of manufacturing the appliance becomes high in relation to its drying capacity and that the working method of the appliance is inappropriate and uneconomical.
Formålet med opfindelsen er at tilvejebringe et apparat af den indledningsvis nævnte art, ved hvilket de nævnte ulemper er eliminerede, d.v.s. ved hvilket der opnås en større tørrekapacitet og en mere økonomisk drift.The object of the invention is to provide an apparatus of the kind mentioned in the introduction, in which the said disadvantages are eliminated, i.e. which achieves greater drying capacity and more economical operation.
Denne opgave løses iflg. opfindelsen ved, at apparatet omfatter to skiftevis til samme behandlingsproces anvendte kedler, der over parallelle ledninger og et styreorgan og en eneste kondensator er sluttede til et fælles evakueringsapparat, og at kedlernes to tørre-middelkredsløb har en fælles mellem styreorganerne indsat del, som forbinder de to kredsløb med hinanden, og som indeholder en befug-ter samt på i og for sig kendt måde en blæser og en opvarmer. Ved anvendelsen af to kedler og .styreorganer, som forbinder de to kedlers kredsløb med hinanden, opnås at der med en eneste maskinel fenhed, bestående af opvarmeren, blæseren og evakueringsapparatet samt kondensatoren samtidig kan gennemføres en tørring i to kedler på en sådan måde, at når blæseren og opvarmeren er sluttede til den første kedels kredsløb, er den anden kedel sluttet til evakueringsapparatet. Disse aggregater er således kontinuerligt i drift, idet de skiftevis tjener til behandling af den første og den anden kedels indhold, hvorved deres kapacitet udnyttes fuldt ud.This task is solved according to. the invention in that the apparatus comprises two boilers used alternately for the same treatment process, connected over a parallel conduit and a control means and a single capacitor to a common evacuation apparatus, and that the two drying medium circuits of the boilers have a common part inserted between the control means which connects the two circuits with each other, and containing a humidifier and in a manner known per se a fan and a heater. By using two boilers and control means connecting the circuits of the two boilers, it is achieved that with a single mechanical unit consisting of the heater, the fan and the evacuation apparatus as well as the condenser a drying in two boilers can be carried out simultaneously in such a way that when the fan and heater are connected to the circuit of the first boiler, the second boiler is connected to the evacuation apparatus. Thus, these assemblies are continuously in operation, alternately serving to process the contents of the first and second boilers, thereby fully utilizing their capacity.
I det følgende beskrives opfindelsen nærmere under henvisning til en på tegningen anskueliggjort udførelsesform for apparatet ifølge opfindelsen.The invention will now be described in more detail with reference to an embodiment of the apparatus according to the invention illustrated in the drawing.
To kedler 1 og la, i hvilke der er anbragt tørregods f.eks. i form af spoler 2 henholdsvis 2a, er over et kredsløb 2, 3a tilsluttet til en blæser 4 og en opvarmer 5. De to kedler kan således 3 141Λ19 over de lukkede kredsløb 3 henholdsvis 3a betjenes med en dampgasblanding til behandling af tørregodset. Denne damp-gasblanding kan oplades med fugtighed ved hjælp af et befugtningsappa-rat 9. Endvidere kan der i dette område af kredsløbet 3, 3a være anbragt en trykluftkilde 14 til oppumpning af det lukkede kredsløb, hvilket tjener til nedsættelse af luftens tørrekapacitet.Two boilers 1 and 1a, in which drying goods are arranged e.g. in the form of coils 2 and 2a, respectively, over a circuit 2, 3a is connected to a fan 4 and a heater 5. Thus, the two boilers 3 141Λ19 can be operated over the closed circuits 3 and 3a, respectively, with a steam gas mixture for treating the dry goods. This vapor-gas mixture can be charged with humidity by a humidifier 9. Further, in this region of the circuit 3, 3a, a compressed air source 14 may be provided for inflating the closed circuit, which serves to reduce the drying capacity of the air.
Til kedlerne 1 og la er der tilsluttet et yderligere kredsløb 6, 6a med et evakueringsapparat 7 og en foran denne indskudt kondensator 8. Endelig er der anbragt ventilerings- og udluftningsventiler lo henholdsvis loa på kedlerne 1 og la. Kredsløbet 3, 3a kan ved hjælp af elektriske varmeslanger 11, 11a, 11b opvarmes for at forhindre kondensatdannelse i ikke ønskede områder. Når en fastsat temperaturforskel mellem varme- og afgangsgastemperatur er nået, indkobles over et kendt og derfor ikke nærmere vist styringsorgan evakue-ringsapparatet 7jOg hele kredsløbet udpumpes. De derved opstående dampe fortættes i kondensatoren 8. Når det fastsatte vacuum er nået, stopper evakueringsapparatet, og udluftningsventilen lo henholdsvis loa åbnes, indtil kredsløbet er fyldt med frisk gas f.eks. luft fra atmosfæren. Derefter lukker ventilen lo henholdsvis loa.To the boilers 1 and 1a, a further circuit 6, 6a is connected with an evacuation device 7 and a capacitor 8 in front of this. Finally, ventilation and venting valves 1a and 1a are respectively provided on the boilers 1 and 1a. The circuit 3, 3a can be heated by means of electric heat hoses 11, 11a, 11b to prevent condensate formation in undesired areas. When a set temperature difference between heating and exhaust gas temperature is reached, a known and not shown control device evacuation device 7j and the entire circuit is pumped out over a known circuit. The resulting vapors are condensed in the capacitor 8. When the set vacuum is reached, the evacuation apparatus stops and the vent valve lo or loa is opened, respectively, until the circuit is filled with fresh gas e.g. air from the atmosphere. Thereafter, the valve closes or loa closes respectively.
Endelig er der i kredsløbet 3, 3a og i kredsløbet 6, 6a anbragt omstyringsorganer 13, 13a og 13b, som tillader skiftevis tilslutning af kedlen 1 og la til blæseren 4, opvarmeren 5 og befugtningsappa-ratet 9 i kredsløbet 3 henholdsvis 3a og til evakueringsapparatet 7 i kredsløbet 6 henholdsvis 6a. Dermed er de vigtige og dyre aggregater til frembringelse og opretholdelse af tørringsbetingelserne kontinuerligt i drift, nemlig skiftevis til behandling af indholdet i kedlen 1 og af indeholdet i kedlen la. Det er derefter blot de ekstra omstyringsorganer, der kun træder i drift med omstyringen af de to kedlers kredsløb.Finally, in the circuits 3, 3a and in the circuits 6, 6a there are provided control means 13, 13a and 13b which allow alternate connection of the boiler 1 and 1a to the fan 4, the heater 5 and the humidifier 9 in the circuit 3 and 3a respectively, and to the evacuation apparatus. 7 in the circuit 6 and 6a, respectively. Thus, the important and expensive aggregates for generating and maintaining the drying conditions are continuously in operation, namely alternately for processing the contents of the boiler 1 and of the contents of the boiler 1a. It is then only the extra control elements that only enter into operation with the control of the two boiler circuits.
