Opfindelsen angår en sprøjteboks af den i krav l's indledning angivne art.The invention relates to a syringe box of the kind specified in the preamble of claim 1.
En sprøjteboks af denne art er vist og beskrevet i GB patentskrift nr. 941 054. I denne sprøjteboks suges der 5 ved hjælp af en ventilator en luftstrøm fra et sprøjterum, der befinder sig foran luftvaskekammeret over bundkarret, med en opløsning af f.eks. kalciumhydroxid gennem errsmal spalte mellem den savtakkede underkant af den væg, der skiller vaskekammeret fra sprøjterummet, og 10 vandoverfladen. I denne snævre passage bliver luftstrøm men meget kraftig, og på grund af den takkede vægunderkant skabes der en stærk turbulens. Disse forhold bevirker, at der rives vandpartikler med af luftstrømmen, så at den luftstrøm, der suges ind i luftvaske-15 rummet, indeholder en blanding af vandpartikler med op løsningsmiddel og partikler af lak eller maling. I luft-vaskekammeret tvinges luftstrømmen til at følge en zig-zagformet bane mellem et antal skråtstillede afslag-ningsplader, hvorfra vand- og lak- eller malingpartik-20 lerne falder ned i udløbskanalerne, som fører dem til bage i bundkarret. Undervejs bliver lak- eller maling-partiklerne bearbejdet af opløsningen. Det slam, der efterhånden samler sig i bundkarret, må fjernes med mellemrum, hvilket kræver standsning af hele sprøjte-25 boksen, medens rensningsarbejdet finder sted. Det kendte anlæg egner sig heller ikke til brug i forbindelse med sprøjtning med visse nye laktyper, som er tilbøjelig til at danne klæbrige klumper, der kan tilstoppe udløbs-kanalerne .A syringe box of this kind is shown and described in GB Patent No. 941,054. In this syringe box 5, by means of a fan, an air flow from a syringe chamber located in front of the air-washing chamber above the bottom vessel is sucked with a solution of e.g. calcium hydroxide through the scarlet gap between the sawed bottom of the wall separating the wash chamber from the spray chamber and the water surface. In this narrow passage, airflow becomes very powerful, and due to the jagged wall bottom, a strong turbulence is created. These conditions cause water particles to be shredded by the air flow so that the air flow sucked into the air wash room contains a mixture of water particles with solvent and particles of varnish or paint. In the air-washing chamber, the airflow is forced to follow a zig-zag-shaped path between a plurality of inclined cut-off plates, from which the water and lacquer or paint particles fall into the outlet ducts which lead them back into the bottom vessel. Along the way, the lacquer or paint particles are processed by the solution. The sludge which eventually accumulates in the bottom vessel must be removed at intervals, which requires stopping the entire syringe box while the purification work is taking place. The known plant is also not suitable for use in spraying with certain new varnishes which tend to form sticky lumps which can clog the outlet ducts.
30 Opfindelsen har til formål at angive en sprøjteboks af den omhandlede art, som kan anvendes både til gamle og nye laktyper, og som desuden er let tilgængelig for rensning.The invention has for its object to provide a spray box of the kind in question which can be used for both old and new varnishes and which is also readily available for cleaning.

Dette formål opnås ved, at sprøjteboksen er udformet som angivet i krav l's kendetegnende del, idet vejen fra luftvaskekammeret til slamtanken ved denne konstruktion er så kort, at slampartiklerne ikke får tid til at agglu-5 tinere. Desuden kan den separate slamtank let anbringes således, at den kan renses, medens sprøjteboksen er i drift, uden at renseprocessen på nogen måde griber forstyrrende ind i de normale arbejdsoperationer.This object is achieved in that the spray box is designed as defined in the characterizing part of claim 1, in that the path from the air washing chamber to the sludge tank of this construction is so short that the sludge particles do not have time to agglutinate. In addition, the separate sludge tank can be easily placed so that it can be cleaned while the spray box is in operation, without the cleaning process in any way interfering with normal working operations.
En hensigtsmæssig placering af slambassinet, som specielt 10 i forbindelse med brede sprøjtebokse giver korte forbindelser mellem luftvaskekammeret og bassinet, er angivet i krav 2.An appropriate location of the sludge basin, which in particular in connection with wide spray boxes provides short connections between the air-washing chamber and the basin, is stated in claim 2.
Ved den i krav 3 angivne udformning opnås, at returvandet fra slambassinet ledes så langt frem i bundkarret, som 15 det findes ønskeligt af hensyn til vandcirkulationen.In the embodiment set out in claim 3, it is achieved that the return water from the sludge pool is conducted as far forward in the bottom vessel as is desirable for the sake of water circulation.
Den i krav 4 angivne udformning gør det muligt at tage returkanalerne ud til rensning, hvilket også kan gøres uden driftsafbrydelse.The configuration of claim 4 allows the return channels to be removed for cleaning, which can also be done without interruption.
En særlig enkel udførelse af returkanalerne er angivet i 20 krav 5.A particularly simple embodiment of the return channels is set out in claim 5.
For at også udløbskanalerne fra luftvaskekammeret skal kunne udtages til rensning, kan sprøjteboksen hensigtsmæssigt være udformet som angivet i krav 6.In order that the outlet ducts from the air washing chamber can also be taken out for cleaning, the spray box may suitably be designed as claimed in claim 6.
En udførelsesform for sprøjteboksen ifølge opfindelsen er 25 vist skematisk i perspektivisk afbildning og i lodret snit på tegningen og skal i det følgende beskrives nærmere under henvisning dertil.An embodiment of the syringe box according to the invention is shown diagrammatically in perspective view and in vertical section of the drawing and will be described in more detail below with reference thereto.

På tegningen er 10 et rektangulært bundkar, der er fyldt med vand indeholdende en opløsning af f.eks. kalciumhydroxid til det ved 11 viste niveau. Opadgående forlængelser 12 og 13 af bundkarrets forvæg og 5 sidevægge begrænser sammen med to loftplader 14 og en fra den ene af disse udhængende skillevæg 13 et sprøjte-rum. De genstande, der skal sprøjtelakeres, føres igennem sprøjterummet af en ikke vist transportør, der er anbragt oven over sprøjterummet, og hvorfra ikke viste 10 ophængningsorganer for genstandene rager ned gennem en spalte 16 mellem loftpladerne 14. Indføring af genstandene i sprøjterummet foregår gennem en åbning 17 i den viste sidevæg 13. Denne åbning er omsluttet af en i hovedsagen kasseformet indføringssluse 18. En tilsva-15 rende afgangsåbning med udføringssluse findes i den anden, ikke viste sidevæg. Besprøjtning af genstandene foregår fra pladsen foran sprøjteboksen gennem en stor åbning 19 i forvæggen 12.In the drawing, 10 is a rectangular bottom vessel filled with water containing a solution of e.g. calcium hydroxide to the level shown at 11. Upward extensions 12 and 13 of the bottom vessel front wall and 5 side walls together with two ceiling plates 14 and one from one of these hanging partitions 13 restrict a spray space. The articles to be sprayed are passed through the spray chamber by a not shown conveyor disposed above the spray chamber, from which 10 articles of the suspension not shown protrude through a slot 16 between the ceiling plates 14. The articles are introduced into the spray chamber through an opening. 17 in the shown sidewall 13. This opening is enclosed by a generally box-shaped insertion latch 18. A similar outlet opening with an embodiment latch is provided in the second side wall (not shown). The objects are sprayed from the space in front of the spray box through a large opening 19 in the front wall 12.
Skillevæggen 15, som danner bagvæg i sprøjterummet, 20 bærer forneden en kantskinne 20 med savtakket underkant, der befinder sig umiddelbart over vandoverfladen 11.The partition 15, which forms the back wall of the spray compartment 20, carries a bottom rail 20 with a sawed lower edge 20 located immediately above the water surface 11.
Et antal pladeformede lydskærme 21 rager skråt fremad og nedad fra skillevæggen 15 med underkanten beliggende et stykke over vandoverfladen.A plurality of plate-shaped sound screens 21 project obliquely forward and downward from the partition 15 with the lower edge slightly above the water surface.
25 Bag ved sprøjterummet findes et luftvaskekammer, som begrænses af skillevæggen 15, den bageste loftplade 14, de to sidevægge, hvoraf kun den ene 13 ses på tegningen, en bagvæg 22 og en bund 23, som er beliggende et stykke i over vandoverfladen.25 Behind the spray chamber is an air-washing chamber which is limited by the partition wall 15, the rear ceiling plate 14, the two side walls, only one of which 13 is seen in the drawing, a back wall 22 and a bottom 23 which are located slightly above the water surface.
30 Den forreste del af bunden 23 er svagt opadkrummet, og bundens forkant er beliggende et stykke fra skillevæggen 15 og begrænser sammen med denne en indgangsspalte 24.The front portion of the base 23 is slightly upwardly curved, and the front edge of the base is located some distance from the partition 15 and, together with this, limits an entrance gap 24.

En ledeplade 25 har en i det væsentlige plan forreste del 26, som er beliggende et stykke under vandoverfladen, og hvis forkant 27 er beliggende i den del af bundkarret, der danner bund under sprøjterummet. Den 5 bageste del 28 af ledepladen 25 er i hovedsagen halvcylindrisk og strækker sig op i luftvaskekammeret, hvor dens endekant ligger an mod og er fastgjort til undersiden af dette kammers bund 23. Ledepladen 25 understøttes af en skillevæg 29, som opdeler bundkarret 10 10 i et forreste sprøjtebassin 30 og et bageste slambassin 31.A baffle 25 has a substantially planar front portion 26 which is slightly below the water surface and the leading edge 27 of which is located in the portion of the bottom vessel that forms the bottom of the spray chamber. The rear portion 28 of the baffle 25 is generally semi-cylindrical and extends upwardly into the air-washing chamber where its end edge abuts and is attached to the underside of the bottom of this chamber 23. The baffle 25 is supported by a partition 29 which divides the bottom vessel 10 10 into a front spray pool 30 and a rear sludge pool 31.
På luftvaskekammerets vægge 15 og 22 er anbragt dels en prelplade 32, dels afslagningsplader 33, som strækker sig skråt nedad fra væggene og overlapper hinanden, 15 så de danner en zig-zagformet bane for luftstrømmen.On the walls of the air-washing chamber 15 and 22 are arranged partly a baffle plate 32 and partly offset plates 33 which extend obliquely downwards from the walls and overlap one another to form a zig-zag-shaped path for the air flow.
Bunden 23 af luftvaskekammeret er udformet med et antal udløbsåbninger 34, og under hver af disse åbninger er der anbragt en udløbskanal 35, hvis nedre endedel er således krummet, at kanalmundingen kommer til at vende 20 bagud i slambassinet 31. Udløbskanalerne 35 har i den viste udførelse rektangulært tværsnit, og hver kanal har ved sin øvre ende en rundtgående kantflange 36, ved hjælp af hvilken den på ikke nærmere vist måde er ophængt som en skuffe på undersiden af luftvaskekamme-25 rets bund 23. Udløbskanalerne kan således let trækkes ud til rensning eller udskiftning. Om ønsket kan der på flangen 36 eller på selve udløbskanalen være anbragt et ikke vist håndtag.The bottom 23 of the air-washing chamber is formed with a plurality of outlet openings 34, and below each of these openings is provided an outlet duct 35, the lower end of which is curved such that the duct mouth 20 turns backwards in the sludge pool 31. The outlet ducts 35 a rectangular cross-section, and each duct has at its upper end a circumferential edge flange 36, by means of which it is suspended in no way shown as a drawer on the underside of the bottom of the air-washing chamber 25. The outlet ducts can thus easily be pulled out for cleaning. or replacement. If desired, a handle not shown may be provided on the flange 36 or on the outlet duct itself.
Ud for hver udløbskanal 35 har skillevæggen 29 en åbning 30 37, hvori er løst indskudt den bageste ende af en retur kanal 38, som i den viste udførelse har en tværsnits-form som et forholdsvis fladt omvendt U, og hvis forreste ende hviler løst på bunden af sprøjtebassinet 30 5Next to each outlet channel 35, the partition 29 has an opening 30 37, which is loosely inserted in the rear end of a return channel 38, which in the illustrated embodiment has a cross-sectional shape as a relatively flat inverted U, the front end of which rests loosely on bottom of the spray pool 30 5

*♦ i nogen afstand fra forvæggen 12. Den forreste ende af returkanalerne kan eventuelt hvile på ikke viste ben, som får kanalerne til at skråne svagt opad fra slambassinet. Også returkanalerne er let udtagelige 5 med henblik på rensning eller udskiftning og kan om ønsket til dette formål være forsynet med et ikke vist håndtag. For at lette inds-ætning af returkanalerne kan der omkring åbningerne 37 i skillevæggen 29 være anbragt ikke viste tragtformede styreorganer. Indsæt— 10 ning og udtagning kan alt efter ønske ske fra forsiden eller bagsiden af sprøjteboksen.* ♦ at some distance from the front wall 12. The front end of the return ducts may possibly rest on legs not shown, which cause the ducts to slope slightly upward from the sludge pool. Also the return channels are easily removable for cleaning or replacement and may, if desired, be provided with a handle not shown. In order to facilitate insertion of the return channels, funnel-shaped control means (not shown) can be arranged around the openings 37 in the partition 29. Insertion and removal can be done from the front or back of the syringe box as desired.
En rørstuds 39, som går gennem loftpladen 14 over luft-vaskekammeret, sluttes til sugesiden af en blæser, som kan trække en kraftig luftstrøm gen-15 nem åbningen 19 i forvæggen 12, sprøjterummet, spalten mellem kantskinnen 20 og vandoverfladen og den zig-z;ag-formede bane i luftvaskekamimeret.A pipe nozzle 39 passing through the ceiling plate 14 over the air-washing chamber is connected to the suction side of a blower which can draw a strong air flow through the opening 19 in the front wall 12, the spray space, the gap between the edge rail 20 and the water surface and the zig-z. ag-shaped web in air-washing chamber.
Når denne luftstrøm er sat i gang, vil der opstå stærk turbulens i den smalle og på grund af savtakskinnen 70 20 ujævne passage mellem denne og vandoverfladen med det resultat, at vand- og lakpartikler rives med af luftstrømmen ind i luftvaskekammeret. Ved indgangen hertil sættes den i en voldsom hvirvelbevægelse af den krumme del 28 af ledepladen 25. Denne hvirvelbevægelse be-25 virker, at de forskellige partikler blandes intimt m:ed hverandre, så den vandige opløsning får de bedst mulige betingelser for at angribe lakpartiklerne. Fra strømhvirvlen suges den forurenede luft videre op i luftvaskerummet gennem spalten 24 og støder umiddelbart 30 efter imod prelpladen 32, som tvinger den ud i zig-zag- banen mellem afslagningspladerne 33. Efter passagen .gennem denne bane er luften renset for vand- og lakpartikler samt pigmenter, som søger ned mod bunden. I dette 6When this air flow is started, strong turbulence will occur in the narrow and uneven passage between the saw roof rail 70 and the water surface, with the result that water and lacquer particles are pulled by the air flow into the air washing chamber. At its entrance, it is placed in a violent vortex motion of the curved portion 28 of the baffle 25. This vortex motion causes the various particles to mix intimately with each other, so that the aqueous solution is given the best possible conditions to attack the lacquer particles. From the fluid vortex, the contaminated air is further sucked up into the air wash space through the slot 24 and immediately bumps 30 towards the baffle plate 32, which forces it into the zig-zag path between the cut-off plates 33. After passage through this path, the air is purified of water and lacquer particles. as well as pigments that look down to the bottom In this 6

Again, the water will be so strong. movement that the lumps in which the lacquer particles tend to accumulate are constantly broken.
Nogle lak- og malingtyper synker til bunds i slambassinet, andre, navnlig nyere lakker af isocyanattypen, 10 svulmer op og søger op til overfladen.

Under operating conditions, the water level will be somewhat higher in the sludge basin than in the spray basin, and from the area between the bottom of the sludge basin and the water surface, substantially pure water will flow through the return channels 38 to return the spray basin.
Hvad enten maling- eller lakpartiklerne søger ned mod bunden eller op mod overfladen, kan de fjernes med passende mellemrum fra slambassinet, medens sprøjteboksen er i drift, uden at dette på nogen måde influerer på den 25 normale arbejdsproces.Whether the paint or varnish particles are scouring to the bottom or up to the surface, they can be removed at appropriate intervals from the sludge basin while the spray box is in operation, without in any way affecting the normal working process.
