Opfindelsen angår en tryklufttørrer og navnlig en tørrer, der anvendes til at undgå kondensation i rør, der fører til bremser eller andre styreaggregater på lokomotiver.The invention relates to a compressed air dryer and in particular to a dryer used to avoid condensation in pipes leading to brakes or other control units on locomotives.
5 Det er kendt mellem en luftkompressor og en tryk luftbeholder til opbevaring af tør luft af hensyn til et lokomotivs apparatur at indskyde en tryklufttørrer bestemt til at hindre en utilstrækkelig funktion af apparaturet som følge af frysning af kondensat om vinte-10 ren i de talrige dyser i for eksempel bremsekredsløbene.It is known between an air compressor and a compressed air container for storing dry air for the sake of a locomotive's apparatus to insert a compressed air dryer intended to prevent an insufficient function of the apparatus due to freezing of condensate during the winter in the numerous nozzles in, for example, the brake circuits.
For at rense trykluften afkøles denne først, og vand og olie i luften kondenseres eller opsamles i luft-tørreren. En sådan lufttørrer omfatter i en kendt udformning en beholder med fire kamre, nemlig et cylin-15 drisk midterkammer anbragt på bunden af beholderen, af mindre højde end denne og forbundet med trykluftbeholderen, og hvilket kammer er fyldt med aluminiumoxid-kugler eller en anden absorbent for vand, et tomt nedre ringformet kammer, som er forbundet dels med kompresso-20 ren, dels med et rørsystem til udstrømning af regenereret luft, et øvre ringformet kammer fyldt med metalsigter til at absorbere vand- og oliedråber samt et tomt øvre cylindrisk kammer placeret foroven i beholderen.To clean the compressed air, it is cooled first and water and oil in the air are condensed or collected in the air dryer. Such an air dryer comprises in a known design a container with four chambers, namely a cylindrical central chamber arranged on the bottom of the container, of a smaller height than this and connected to the compressed air container, and which chamber is filled with alumina balls or another absorbent for water, an empty lower annular chamber which is connected partly to the compressor and partly to a pipe system for the outflow of regenerated air, an upper annular chamber filled with metal sieves to absorb water and oil droplets and an empty upper cylindrical chamber located at the top of the container.
Ved normal drift strømmer trykluft ind i det nedre 25 ringformede kammer, gennem det øvre ringformede kammer, derfra gennem det øvre cylindriske kammer og op gennem midterkammeret.In normal operation, compressed air flows into the lower annular chamber, through the upper annular chamber, thence through the upper cylindrical chamber and up through the central chamber.
Når kompressoren standser tilførslen til tryk-luftbeholderen, returneres tør oplagret trykluft gennem 30 tørreren i modsat retning af tidligere og regenererer absorbenten, som er mættet med vand under den normale funktion. Den kendte tørrer udgøres af en klokke, som hviler med fødder på underlaget, og som følge af de tykke vægge, som skal modstå de betydelige tryk, som 35 hersker i beholderen, er klokken tung og vanskelig at løfte. En sådan løfteoperation, som udføres manuelt, 144508 2 skal foretages, hver gang man skal foretage en vedligeholdelse af tørreren bestående i udskiftning af alu-miniumoxidkuglerne og/eller metalsigterne. På grund af det nødvendige store rumfang for udførelsen af de to 5 filtreringsfunktioner er den kraft, som trykket udøver på beholderens bund, ligeledes meget stort, og det samme gælder flangerne til fastgørelse af klokken på bunden af beholderen. Som følge heraf er de hidtil kendte tørrere pladskrævende, tunge og vanskelige at vedli-10 geholde.When the compressor stops supplying the compressed air tank, dry stored compressed air is returned through the dryer in the opposite direction to before and regenerates the absorbent, which is saturated with water during normal operation. The known dryer consists of a bell which rests with feet on the ground, and due to the thick walls which are to withstand the considerable pressures prevailing in the container, the bell is heavy and difficult to lift. Such a lifting operation, which is performed manually, must be performed every time a maintenance of the dryer consisting of replacing the alumina balls and / or the metal sieves is to be performed. Due to the large volume required for performing the two filtration functions, the force exerted by the pressure on the bottom of the container is also very large, as are the flanges for attaching the bell to the bottom of the container. As a result, the prior art dryers are bulky, heavy and difficult to maintain.
Der kendes dog også, se f.eks. DE-PS 918,043 tørrere med filterbeholdere, hvor filterlegemet kan udtages gennem beholderens ende efter afmontering af et påflanget dæksel, men disse opviser koncentrisk anbragte 15 filterbeholdere til forskel fra den foreliggende tryk-lufttørrer, som er af den art, som omfatter et første filter af metalfibre og et andet filter af et vanddampabsorberende stof, f.eks. aluminiumoxid, gennemstrømmet i serie af trykluft fra en kompressor til en 20 beholder for tør og renset trykluft, der er beregnet til, når kompressoren er standset, at kunne sendes i modsat retning til regenerering af absorbenten.However, it is also known, see e.g. DE-PS 918,043 dryers with filter containers, where the filter body can be removed through the end of the container after removal of a flanged cover, but these have concentrically arranged filter containers in contrast to the present compressed air dryer, which is of the type comprising a first filter of metal fibers and another filter of a vapor-absorbing substance, e.g. alumina, flowing in series of compressed air from a compressor to a container for dry and purified compressed air, which, when the compressor is stopped, can be sent in the opposite direction for regeneration of the absorbent.
Tryklufttørreren ifølge opfindelsen eliminerer de ovenfor angivne ulemper. I forhold til de kendte tryte-25 lufttørrere har tørreren ifølge opfindelsen en bedre ydelse med et mindre rumfang og ligeledes mindre vægt, og vedligeholdelsen er særlig let.The compressed air dryer according to the invention eliminates the above-mentioned disadvantages. Compared to the known compressed air dryers, the dryer according to the invention has a better performance with a smaller volume and also less weight, and the maintenance is particularly easy.
Tryklufttørreren ifølge opfindelsen er ejendommelig ved, at de to filtre findes i hver sin hovedsagelig 30 cylindriske beholder, der er forbundet indbyrdes gennem et rør, og af hvilke den første indeholder metalfiber-filteret og foroven har et aftageligt dæksel samt forneden en åbning til aftapning af kondensat, medens den anden beholder indeholder absorbenten og foroven har en 35 hals afsluttet med en aksial åbning lukket med en aftagelig prop samt forneden en bundåbning forbundet med 3 144509 trykluftbeholderen og en anden åbning lukket med en aftagelig prop til udtagning af absorbenten ved hjælp af tyngdekraften.The compressed air dryer according to the invention is characterized in that the two filters are located in separate cylindrical containers, which are interconnected through a pipe, the first of which contains the metal fiber filter and at the top has a removable cover and at the bottom an opening for draining condensate, while the second container contains the absorbent and at the top has a neck closed with an axial opening closed with a removable plug and below a bottom opening connected to the compressed air container and a second opening closed with a removable plug for removing the absorbent by gravity .
Ifølge opfindelsen kan forbindelseskanalen mel-5 lem de to beholdere have et finmasket gitter fastholdt med en ringformet fjederklemme.According to the invention, the connecting channel between the two containers can have a fine-mesh grid held with an annular spring clamp.
Opfindelsen forklares nærmere i det følgende ved hjælp af et udførelseseksempel på en tørrer ifølge opfindelsen og under henvisning til tegningen, som ske-10 matisk viser et længdesnit gennem tryklufttørreren.The invention is explained in more detail in the following by means of an exemplary embodiment of a dryer according to the invention and with reference to the drawing, which schematically shows a longitudinal section through the compressed air dryer.

Den anden beholder 15 2, som også er cylindrisk, skal absorbere vanddamp, som endnu findes i trykluften. Den cylindriske beholder .The drawing shows a compressed air dryer which comprises two containers 1 and 2. One container 1 is cylindrical and serves to stop water and oil particles which are suspended in the compressed air. The second container 15 2, which is also cylindrical, is to absorb water vapor which is still present in the compressed air. The cylindrical container.
I har et rumindhold på ca. 15 dm . På en sidevæg diametralt modsat beholderen 2 findes en åbning 3, i hvilken der sidder et rør 4, som er forbundet med en 20 ikke vist kompressor og en ikke vist køler.

Dette filter 11 har form af en cylinder inden i beholderen 1.These lugs carry a perforated plate 7 of stainless steel which, together with a corresponding plate 8 and rods 9 and 10 ending in tips, hold a filter II of metal fibers compactly together. This filter 11 is in the form of a cylinder inside the container 1.
På en sidevæg af beholderen 1 ud mod beholderen 2 findes en åbning 12, som er forbundet med be-30 holderen 2 gennem en forbindelseskanal i form af et rør 13. Beholderen 1 har en cirkulær flange 14 foroven, hvorpå der aftageligt er fastgjort en flange 15 for et dæksel 16. Sammenspændingen af flangerne 144509 4 15 og 16 sker ved hjælp af bolte. En pakning 17 i en not i flangen 14 giver tætning af beholderen.On a side wall of the container 1 towards the container 2 there is an opening 12, which is connected to the container 2 through a connecting channel in the form of a pipe 13. The container 1 has a circular flange 14 at the top, to which a flange is removably attached. 15 for a cover 16. The tightening of the flanges 144509 4 15 and 16 is done by means of bolts. A gasket 17 in a groove in the flange 14 provides sealing of the container.
Et rør 18, som er fastgjort til dækslet, går ned indvendigt i beholderen 1 til niveauet for den perfore-5 rede plade 8 for at forhindre løftning af filteret 11 under kompressorens drift. I bunden af beholderen 1 findes en åbning 19, som tjener til udtømning af kondensat, vand, olie og urenheder, som har samlet sig på bunden.A tube 18 attached to the cover descends inside the container 1 to the level of the perforated plate 8 to prevent lifting of the filter 11 during the operation of the compressor. At the bottom of the container 1 there is an opening 19 which serves to discharge condensate, water, oil and impurities which have accumulated on the bottom.
10 Beholderen 2 har et rumindhold på ca.The container 2 has a volume of approx.
3 12 dm . Den indeholder en absorbent i form af alumini-umoxidkugler. I bunden af beholderen findes en åbning 20, der er forbundet med et rør 21 til udstrømning for tør trykluft eller tilførsel af tør luft med henblik 15 på regenerering af aluminiumoxiden. Ved indgangen for røret 21 er indsat en spærrerist 22, som forhindrer passagen af aluminiumoxidkugler.3 12 dm. It contains an absorbent in the form of alumina spheres. At the bottom of the container there is an opening 20 which is connected to a pipe 21 for outflow of dry compressed air or supply of dry air for the purpose of regenerating the alumina. At the inlet of the pipe 21 a barrier grate 22 is inserted, which prevents the passage of alumina balls.
Ved siden af åbningen 20 findes en anden åbning 23, som er lukket med en prop, og som tjener 2Q til at tømme beholderen efter behov. Foroven i beholderen 2 findes en hals 24, som ender i en aksial åbning 25, og som har en sideåbning 26, der er forbundet med røret 13 til forbindelse med beholderen 1. I dette rør 13 er anbragt en cirkulær 25 spærresigte fastgjort ved hjælp af en ringformet fjederklemme. Denne spærresigte 27 af rustfrit stål har til opgave at forhindre aluminiumoxidkugler i at strømme over i beholderen 1 under regenereringen på grund af det tryk, som hersker i bunden af beholderen 2.Next to the opening 20 is another opening 23, which is closed with a stopper and which serves 2Q to empty the container as needed. At the top of the container 2 there is a neck 24 which ends in an axial opening 25 and which has a side opening 26 which is connected to the tube 13 for connection to the container 1. In this tube 13 a circular 25 blocking sieve is arranged fixed by means of an annular spring clamp. The purpose of this stainless steel barrier screen 27 is to prevent alumina balls from flowing into the container 1 during the regeneration due to the pressure prevailing in the bottom of the container 2.
3Q Apparatets totale omfang er for samme effekt mindre end ved kendte apparater til trods for, at det har to beholdere. Tørrerens totale vægt er af størrelsesordenen 50 kg, hvilket er en fordel, da vægtbegrænsning er af betydning for et lokomotiv, hvor de dele, som 35 transporteres, bør være så lette som muligt. Vedligeholdelsen af tørreren er let, og det er ikke nødvendigt med anstrengende håndtering af tørreren, da det er til-3Q The total scope of the appliance is for the same effect smaller than with known appliances, despite the fact that it has two containers. The total weight of the dryer is of the order of 50 kg, which is an advantage as weight limitation is important for a locomotive, where the parts that are transported should be as light as possible. Maintenance of the dryer is easy and no effort is required to handle the dryer as it is necessary.
