Abstract

Silencer comprising a closed container comprising a side wall (3) having an elliptical shape, a top, a bottom and an input (1) and an output (2). Exhaust gases from a combustion engine are brought into the interior of the container at a first focusing point (4), and being collected in a second focusing point (5) after reflection from the side wall (3). In the second focusing point (5) a sound absorbing material (6) absorbs the sound waves and the gases thereafter exits the silencers through the output (2).

Description

Anordning ved bokser for sproytemaling. Device for cans for spray paint.

Foreliggende oppfinnelse vedrorer en anordning ved bokser eller avlukker for sproytemaling, i hvilken tilfort ventila-sjons luft suges ut til en etterfølgende dråpefraskillergjennom en horisontal spalte. Spalten ligger i sproyteboksens nedre del langs og under en eller flere vertikale eller hellende vannfuktede innervegger. Spalten dannes mellom en nedre kant av innerveggen som er ombbyet inn mot sprdyteboksen, og en i hovedsaken vertikal flens som er festet til en i det vesentlige horisontal plate anordnet over et væskebasseng. The present invention relates to a device for boxes or cubicles for spray painting, in which supplied ventilation air is sucked out to a subsequent drop separator through a horizontal slot. The gap is located in the lower part of the spray box along and under one or more vertical or inclined water-moistened inner walls. The gap is formed between a lower edge of the inner wall which is bent towards the spray box, and a mainly vertical flange which is attached to a mainly horizontal plate arranged above a liquid pool.

Ved de hittil kjente konstruksjoner renner det vann som ikke folger med luftstrommen, forbi spalten og ned i det under-liggende basseng. En stor del av vannet utnyttes således ikke til With the previously known constructions, water that does not follow the air flow flows past the gap and into the underlying pool. A large part of the water is thus not used

o.ppblanding med den med malingpartikler blandede luft. o.pp mixing with the air mixed with paint particles.

Formålet med oppfinnelsen er å eliminere, disse'ulem-per, hvilket oppnås i det vesentlige ved at anordningen har de i patentkrav 1 angitte trekk. The purpose of the invention is to eliminate these disadvantages, which is essentially achieved by the device having the features specified in patent claim 1.

Den forbedrede tekniske virkning beror i det vesentlige på at det vann som renner forbi spalten og ned på stenkplaten, deles opp ved stdt når det faller mot platen. Derved rykkes en del av vanndråpene inn i spalteåpningen samtidig som spaltens nedre del blir våt og bidrar til bket vannsugning gjennom spalten. The improved technical effect is essentially due to the fact that the water that flows past the gap and down onto the sprinkler plate is divided by the stdt when it falls against the plate. Thereby some of the water droplets are moved into the slot opening at the same time as the lower part of the slot becomes wet and contributes to increased water suction through the slot.

Ved en særlig egnet utfbrelse av oppfinnelsen utgjores spalteåpningens nedre kant som befinner seg bak stenkplaten, av en bevegelig flens som ved behov kan forskyves i hovedsaken loddrett på stenkplaten. Derved kan avstanden mellom stenkplatens plan og spaltens nedre kant og spalteåpningens stbrrelse innstilles til verdier som er egnet for fuktning av den nedre kant og medrykking av finfordelte vanndråper. In a particularly suitable embodiment of the invention, the lower edge of the slot opening, which is located behind the sprinkler plate, is made of a movable flange which, if necessary, can be displaced essentially vertically on the sprinkler plate. Thereby, the distance between the plane of the sprinkler plate and the lower edge of the slot and the vertical movement of the slot opening can be set to values that are suitable for wetting the lower edge and entrainment of finely distributed water droplets.

Et utfbrelseseksempel på oppfinnelsen skal beskrives nærmere i tilslutning til tegningen,som viser et snitt av en sprbytemaleboks med anordningen ifblge oppfinnelsen anvendt. An exemplary embodiment of the invention shall be described in more detail in connection with the drawing, which shows a section of a sprby template box with the device according to the invention used.

Spalten 1 er dannet mellom den nedre ombbyde kant 2 av innerveggen 11 og en i hovedsaken vertikal flens *+ som er festet til en i det vesentlige horisontal plate 12 anordnet over et væskebasseng 5. Platen er forlenget inn mot sprbyteboksen og danner en stenkplate 3 foran spalten 1. Ventilasjonsluften som inne-holder malingpartikler bundet til vanndråper, suges ut til en The gap 1 is formed between the lower curved edge 2 of the inner wall 11 and an essentially vertical flange *+ which is attached to an essentially horizontal plate 12 arranged above a liquid pool 5. The plate is extended towards the sprbyte box and forms a splash plate 3 in front slot 1. The ventilation air, which contains paint particles bound to water droplets, is sucked out to a

etterfblgende dråpefraskiller, hvorfra den rensede luft trer ut gjennom en åpning 7. subsequent drop separator, from which the purified air exits through an opening 7.

For å hindre at luften passerer inn i dråpefra-skilleren ved siden av spalten, er platen 12 forsynt med en skjerm 6 som stikker ned i væskebassenget. In order to prevent the air from passing into the droplet separator next to the slot, the plate 12 is provided with a screen 6 which protrudes into the liquid pool.

Sideveggen 11 tilfores vann fra en tank 9 som på sin side mates gjennom et munnstykke 8. Vannet renner over tankens 9 kant lo og langs sideveggen 11 ned til spalteåpningen 1. The side wall 11 is supplied with water from a tank 9 which in turn is fed through a nozzle 8. The water flows over the edge of the tank 9 and along the side wall 11 down to the slit opening 1.

Claims

1. Device at boxes or cubicles for spray paint, in which supply ventilation air is sucked out to a subsequent drop separator through a horizontal slit located in the lower part of the spray box along and under one or more vertical or inclined water-moistened inner walls and is formed between a lower edge of the inner wall which is bent towards the spray exchange box, and one in the main body vertical flange which is attached to an essentially horizontal plate arranged above a liquid basin, characterized in that the plate G.2) is extended towards the box to form a splash plate (3) lying in front of the extraction gap (l).

2. Device according to claim 1, characterized in that the flange (h) is arranged so that, if necessary, it can be shifted perpendicularly to the plate (12) for variation of the slot width.
