Description
Apparat til avfetting av gjenstander. Apparatus for degreasing objects.
Foreliggende oppfinnelse angår et apparat til avfetting av gjenstander ved hjelp av et opplosningsmiddel, fortrinnsVis en klorert hydrokarbon, i alminnelighet trikloretylen og tetraklor-etylen. Med avfetting skal det herunder forståes fjernelse av fett eller olje eller forurensninger inneholdende fett og/eller olje. Oppfinnelsen angår ikke bare behandling av gjenstandene med et flytende oppvarmet oppl6sningsmiddel>men også behandling av gjenstandene med damp fra et kokende opplfisningsmiddel resulter-ende i damp som kondenserer på de forholdsvis kolde gjenstander og derved opplfiser olje og fett. The present invention relates to an apparatus for degreasing objects using a solvent, preferably a chlorinated hydrocarbon, generally trichloroethylene and tetrachloroethylene. Degreasing shall hereunder be understood as the removal of fat or oil or contaminants containing fat and/or oil. The invention not only concerns treatment of the objects with a liquid heated solvent, but also treatment of the objects with steam from a boiling solvent resulting in steam that condenses on the relatively cold objects and thereby dissolves oil and fat.
Det er kjent apparater til avfetting av gjenstander av den foran antydede type, omfattende en beholder for et flytende opp- løsningsmiddel, en oppvarmningsanordning for å bringe opplbsnings-midlet i beholderen til å koke, over denne beholder et rom for den derved dannede opplosningsmiddeldarnp,: an med dobbelte vegger forsynt kjoleanordning for kjoling av veggen i damprommet for kondensering" av dampen, og ventilasjonsanordninger for frembringelse av en Iuft3tr6m for å hindre dampinneholdende luft i å lekke ut av apparatet, hvorunder ventilasjonsanordningen er innrettet til å lede luftstrommen gjennom kjSleanordningen slik at ventilasjonsluften også utnyttes som et f6rste kjfilemiddel. There are known devices for degreasing objects of the type indicated above, comprising a container for a liquid solvent, a heating device for bringing the solvent in the container to a boil, above this container a space for the resulting solvent mixture: a double-walled skirting means for skirting the wall of the steam room for condensation of the steam, and ventilation means for producing a Iuft3tr6m to prevent steam-containing air from leaking out of the apparatus, wherein the ventilation means is arranged to direct the air stream through the heating means so that the ventilation air also used as a first cooling agent.
Det er et oyemed for oppfinnelsen å skaffe et apparat av den foran angitte art som kan drives med minimalt forbruk av kjole-vann. Dette er ifolge oppfinnelsen oppnådd ved at kjoleanordningen dessuten inneholder anordninger omfattende dyser for inn-sproytning av vann som et annet kjOlemiddel i mellomrommet mellom de dobbelte vegger, slik at kjoleeffekten forsterkes av den av luftstrommen frembragte fordampning av vannet. It is an object of the invention to provide an apparatus of the above type which can be operated with minimal consumption of washing water. According to the invention, this is achieved by the skirting device also containing devices comprising nozzles for injecting water as another coolant into the space between the double walls, so that the skirting effect is enhanced by the evaporation of the water produced by the air stream.
I overensstemmelse hermed vil ventilasjonsluften ved apparatet ifolge oppfinnelsen tjene to formål, nemlig é.Jhindre ukonfe • trollert utstrOmning av opplbsningsmiddel til omgivelsene og kjCl-ing av kjolevannet. Det siste 6yemed oppnås i det vesentligste ved fordampning av kjolevannet, idet den derved dannede vanndamp fjernes sammen med ventilasjonsluften. Vannforbruket vil således ikke overstige den vannmengde som trenges til denne fordampning. In accordance with this, the ventilation air at the device according to the invention will serve two purposes, namely 1. To prevent uncontrolled release of solvent to the surroundings and cooling of the cooling water. The last 6yemed is essentially achieved by evaporation of the water, the resulting water vapor being removed together with the ventilation air. The water consumption will thus not exceed the amount of water needed for this evaporation.
Oppfinnelsen skal nå beskrives under henvisning til ved-lagte tegning. Fig. 1 illustrerer en utfCrelsesform for oppfinnelsen. Fig. 2 illustrerer en annen utforelsesform for kjoleanordningen0 The invention will now be described with reference to the attached drawing. Fig. 1 illustrates an embodiment of the invention. Fig. 2 illustrates another embodiment of the dress device 0
Apparatet ifOlge fig. 1 omfatter en beholder 1 i hvis nedre del der befinner seg et flytende opplbsningsmiddel 2. OpplCsnings-midlet oppvarmes til kokning ved hjelp av elektriske heteelementer 3*Dampen fyller den midtre del 4 av apparatet.. Genstandene The device according to fig. 1 comprises a container 1 in the lower part of which there is a liquid solvent 2. The solvent is heated to boiling by means of electric heating elements 3*The steam fills the middle part 4 of the apparatus.. The objects
som skal avfettes senkes ned i denne midtre del 4«which is to be degreased is lowered into this middle part 4«
Den ovre del av apparatet har dobbelte vegger 5a og 5b«En vertikal skillevegg 6 er anordnet i den 6vre del av rommet mellom disse vegger og oppdeler derved rommet mellom veggene i to ad-skilte rom 7 og 8. Veggene 5a og 5D danner en beholder for et v^jinforråd 9 under skilleveggene 6. Nivået av vannet i dette forråd holdes konstant ved hjelp av en flottOr 13 som påvirker en ventil 14 i et vanntilfQrselsror 15 for kompensering av vann som The upper part of the apparatus has double walls 5a and 5b. A vertical dividing wall 6 is arranged in the upper part of the space between these walls and thereby divides the space between the walls into two separate rooms 7 and 8. The walls 5a and 5D form a container for a water reservoir 9 under the partitions 6. The level of the water in this reservoir is kept constant by means of a float 13 which affects a valve 14 in a water supply pipe 15 to compensate for water which
går tapt. is lost.
InnlBpssiden for en pumpe 10 står i forbindelse med vanntilforselen 9 og utlopssiden for denne pumpe står gjennom en ledning 11 i forbindelse med dyser 12 i den 6vre del av rommet The inlet side of a pump 10 is in connection with the water supply 9 and the outlet side of this pump is through a line 11 in connection with nozzles 12 in the outer part of the room
7«Som folge herav vil sproytevann stromme ned i rommet J. 7"As a result, spray water will flow down into room J.
Dette sproytevann moter en luftstrOm som frembringes ved hjelp av en sugevifte, som ikke er:vist på tegningen, og som This spray water creates an air stream which is produced by means of a suction fan, which is not shown in the drawing, and which
står i forbindelse med rommet 7 gjennom en ledning 19. Luften trer inn i apparatet gjennom en sliss 16 som strekker seg om-kring apparatets innlSpsåpning. Opplosningsmiddeldarnp som ellers ville lekke ut til den omgivende atmosfære, fOlger med denne luft. Luften passerer ned gjennom rommet 8, kjoler den ovre del av veggen 5h og passerer derefter opp gjennom rommet 7»mens kjole-vann strSmmer ned. Den fuktige luft suges ut gjennom ledningen 19. is connected to the room 7 through a line 19. The air enters the device through a slot 16 which extends around the device's inlet opening. Solvent dust, which would otherwise leak out to the surrounding atmosphere, follows with this air. The air passes down through room 8, coats the upper part of the wall 5h and then passes up through room 7, while coat water flows down. The moist air is sucked out through line 19.
Det overste nivå av opplosningsmiddeldarnp er bestemt å.v en vertikal vegg 18. Den tunge oppl6sningsålddeldamp strCmmer over overkanten av denne vegg og kommer således i berSring med den vannkjolte del av veggen 5b«.Dampen kondenserer på dénne kolde vegg og det flytende opplosningsmiddel strCmmer tilbake til koke-sonen 2 gjennom et ror 17»og passerer herunder, gjennom en vann-utskiller og alkalisator 20 for fjernelse av sure forurensninger. The uppermost level of the solvent is determined by a vertical wall 18. The heavy solvent vapor flows over the upper edge of this wall and thus comes into contact with the water-cooled part of the wall 5b. The vapor condenses on this cold wall and the liquid solvent flows back to the cooking zone 2 through a rudder 17" and passes below, through a water separator and alkalizer 20 for the removal of acidic contaminants.
Små mengder vann trer inn i apparatet, f.eks. ved at noe vann fBlger med gjenstandene som skal avfettes. Dett© vann frem-bringer en sone bestående av en aaeotropisk blanding av damper av vann og opplosningsmiddel, hvilken sone befinner seg like over veggen 18. HOyden av denne sone er begrenset av luften som suges inn gjennom slissen 16 og kjOler derved den 6vre del av veggen 5b. Small amounts of water enter the device, e.g. in that some water comes with the items to be degreased. This water produces a zone consisting of an aeotropic mixture of vapors of water and solvent, which zone is located just above the wall 18. The height of this zone is limited by the air that is sucked in through the slot 16 and thereby cools the outer part of the wall 5b.
På fig. 2 er anvendt samme henvisningstall for tilsvarende deler som er vii£ på fig. 1. IfGige fig. 2 er rommet mellom, de, dobbelte vegger 5a og 5b ikke oppdelt med en skillevegg, men ven-tilas jonsluf ten passerer rett ned gjennorn rommet fra innlCps-spalten 16 bg trekkes, ut gjennom roret 1°<, son ståy i forbindelse, med den nedre del av dette rom. Kjeiévann tilfcréa gjennom et ror 25 til dyser 12 som sprOytér ut vannet sqsi fin$ dråper• Dråpene fordamper helt eller delvis* mens dé passerer ned gjennom rommet. Eventuelt gjenværende iklce-fordampeV varn».tappes ut gjennom et ror 24* Denne gjenværende vannmengd* holdes p& et. minimum ved at den tilforte vannmengde tilpasses til den kjolevirkning som trenges. Denne tilpassing finner for det forste sted ved at dysene 12 er dimensjonert noyaktig for den vannmengde som svarer til den maksimale kjolemiddelmengde som trenges, eller for ehlitt storre mengde og for det annet ved at vanntilfOrselen avstenges når det ikke trenges kjolemiddel, dvs. når dampnivået befinner seg under overkanten av veggen 18. Dette vil i alminnelighet være tilfelle når nye kolde gjenstander innfores i apparatet. En termostat 21 er anordnet i avfettingskammeret ved det nivå som bestemmes av overkanten av veggen 18. Når opplosningsmiddeldarnp når dette nivå, påvirker termostaten 21 et magnetrelé 22 som åpner en ventil 23 i tilforselsrOret 25 for kjølevann. In fig. 2, the same reference number is used for corresponding parts which are vii£ in fig. 1. IfGige fig. 2, the space between the double walls 5a and 5b is not divided by a dividing wall, but the ven-tilas ion air passes straight down through the space from the inlet gap 16 bg is drawn, out through the rudder 1°<, so stays in connection, with the lower part of this room. Boiling water is supplied through a pipe 25 to nozzles 12 which spray out the water as fine droplets • The droplets evaporate in whole or in part* as they pass down through the room. Any remaining iklce-evaporateV varn» is drained out through a pipe 24* This remaining amount of water* is kept at & et. minimum in that the added amount of water is adapted to the dressing effect that is needed. This adaptation takes place, firstly, by the nozzles 12 being dimensioned precisely for the amount of water that corresponds to the maximum amount of cooling agent needed, or for a slightly larger amount, and secondly, by the water supply being shut off when no cooling agent is needed, i.e. when the steam level is itself under the upper edge of the wall 18. This will generally be the case when new cold objects are introduced into the appliance. A thermostat 21 is arranged in the degreasing chamber at the level determined by the upper edge of the wall 18. When the solvent content reaches this level, the thermostat 21 affects a magnetic relay 22 which opens a valve 23 in the supply pipe 25 for cooling water.
