Abstract
Description
7806608-1 En luftinmatningskanal 8 ansluter sig till luft- öppninqen i eldstadsväqqen. I kanalen 8 har anpassats ett kom- binerat reglerings- och rengöringsorgan, vars väsentliga delar är två skovelaktiga organ 1, som vid en sida är vändbart lagrade i drivstângen 2 med leder 3, vilkas vändaxel ligger väsentligen vinkelrätt mot luftkanalens 8 längdaxel. Drivstången 2 är axiellt förskjutbar inom ett stödrör 4. Vid stödrörets 4 ända har fästs två styrplàtar 5, som ligger på stångens 2 båda sidor. På styr- plåtarna 5 finns långsträckta V-formiga spår 6. Vid skovlarnas l sidokanter befintliga tenar 7 är anpassade för att glida i spåren 6. Lägena av spåren 6 är så anpassade, att medan stången 2 rör sig axiellt inom stödröret 4, öppnas och sluts skovlarna l för att öppna och sluta luftöppningen. Genom att förändra driv- stånqens 2 och stödrörets 4 ömsesidiga läge kan vinkeln mellan skovlarna 1 anpassas efter önskan och således inställs volymen av de delöppningar, som bildas i öppningens nedre och övre del. 7806608-1 An air supply duct 8 connects to the air opening in the fireplace path. In the duct 8 a combined regulating and cleaning member has been adapted, the essential parts of which are two vane-like members 1, which on one side are rotatably mounted in the drive rod 2 with joints 3, the turning axis of which is substantially perpendicular to the longitudinal axis of the air duct 8. The drive rod 2 is axially displaceable within a support tube 4. At the end of the support tube 4, two guide plates 5 are attached, which lie on both sides of the rod 2. On the guide plates 5 there are elongate V-shaped grooves 6. At the side edges of the vanes 1 the tines 7 are adapted to slide in the grooves 6. The positions of the grooves 6 are adapted so that while the rod 2 moves axially within the support tube 4, close the vanes l to open and close the air opening. By changing the mutual position of the drive rod 2 and the support tube 4, the angle between the vanes 1 can be adjusted as desired and thus the volume of the partial openings formed in the lower and upper part of the opening is adjusted.
Genom val av spårens 6 riktning och form àstadkommes utom regle- ring av luftmängdcn också luftströmningens önskade riktning och fördelning.By selecting the direction and shape of the grooves 6, in addition to regulating the amount of air, the desired direction and distribution of the air flow is also achieved.
För att göra möjligt ett rengöringsslag med det av skovlarna l bestående reglerings- och rengöringsorganet är också stödröret 4 axiellt glidbart i förhållande till kanalen 8.In order to enable a cleaning stroke with the regulating and cleaning means consisting of the vanes 1, the support tube 4 is also axially slidable in relation to the channel 8.
Vid drivstángens andra ända har i detta syfte fästs en tvär- stàng 9, som samtidigt förenar två eller flera luftmunstycken.To this end, a cross bar 9 is attached to the other end of the drive rod, which simultaneously connects two or more air nozzles.
Tvärstángen 9 är förskjutbar med hjälp av en luftcylinder (ej visad) antingen i riktning mot eldstaden eller bortåt. En regel 10 förhindrar stödrörets 4 rörelse mot eldstaden tills ett vid stàngen 9 fäst hjul eller en kam öppnar regeln 10. Nu (fig. 2, läget som ritats med enhetlig linje) har reglerings- och ren- göringsskovlarna 1 helt öppnats. Efter det att regeln 10 öppnats, rör sig både stödröret 4 och stången 9 tillsammans mot eldstaden, varvid skovlarna 1, som tränger sig genom öppningen in i eld- staden, löser stoffet som stockat sig omkring luftöppningen (fig. 2, läget som visats med streckad linje). Luftcylindern returnerar rengörings- och regleringsorganet automatiskt, varvid stödröret 4 med styrplàtarna 5 alltid stannar i samma läge och drivstången 2 stannar i det läge som bestämmes av reglerings- skruven ll. Regleringsskruvens läge är reglerbart. Således kan regleringen trots rengöringsrörelsen alltid stanna i samma, 78066 08-1 tidigare bestämt läge. Rengöringsrörelsen kan startas manuellt med en manöverknapp eller med ett kopplingsur. Man kan också använda en gränslägesbrytare, som indikerar om rengöringsorganet kom till botten; om inte, så upprepar cylindern rengörings- rörelsen. Rengöringen kan också programmeras att rotera i pannan så att impulsen alltid kommer från det förra rengöringsorganets cykel. Också en lampa kan användas, som signalerar om något rengöringsorgan inte kom till botten.The crossbar 9 is displaceable by means of an air cylinder (not shown) either in the direction of the fireplace or outwards. A latch 10 prevents the support tube 4 from moving towards the fireplace until a wheel or a cam attached to the rod 9 opens the latch 10. Now (Fig. 2, the position drawn with a uniform line), the adjusting and cleaning vanes 1 have been fully opened. After the latch 10 has been opened, both the support tube 4 and the rod 9 move together towards the fireplace, whereby the vanes 1, which penetrate through the opening into the fireplace, dissolve the substance which has accumulated around the air opening (fig. dashed line). The air cylinder returns the cleaning and regulating means automatically, the support tube 4 with the guide plates 5 always remaining in the same position and the drive rod 2 remaining in the position determined by the regulating screw 11. The position of the adjusting screw is adjustable. Thus, despite the cleaning movement, the control can always stay in the same, 78066 08-1 previously determined position. The cleaning movement can be started manually with a control button or with a timer. You can also use a limit switch, which indicates if the cleaning means came to the bottom; if not, the cylinder repeats the cleaning movement. The cleaning can also be programmed to rotate in the boiler so that the impulse always comes from the cycle of the previous cleaning means. A lamp can also be used, which signals if a cleaning device has not reached the bottom.
Med ovan beskrivet kombinerat reglerings- och rengöringsorgan vinns följande föredelar i jämförelse med mot- svarande kända konstruktioner: l) Luftöppningen består av två delöppningar, den nedre och den övre. Deras ömsesidiga förhållande kan väljas vid tillverkningen. Det här är fördelaktigt speciellt i sodapannor, där man vill ha en liten nedàtriktad luftjet i närheten av primärluftöppningen så att stoffblocket inte kommer för nära till öppningen, och å andra sidan en sned, uppåt riktad ström- ning för att stoffblockets form skulle bli riktig. 2) Under rengöringsrörelsen arbetar också regle- rinqsmekanismen och blir därför inte blockerad. 3) Underhàllet av det kombinerade reglerings- och renqöringsorganet är lätt, då organet är enkelt att avlägsna från luftkanalen.With the above-described combined regulating and cleaning means, the following advantages are obtained in comparison with corresponding known constructions: l) The air opening consists of two sub-openings, the lower and the upper. Their mutual relationship can be chosen at the time of manufacture. This is advantageous especially in recovery boilers, where you want a small downwardly directed air jet near the primary air opening so that the fabric block does not come too close to the opening, and on the other hand an oblique, upward flow for the shape of the fabric block to be correct. 2) During the cleaning movement, the control mechanism also works and is therefore not blocked. 3) The maintenance of the combined regulating and cleaning means is easy, as the means is easy to remove from the air duct.
