Description

Uppfinnare: T Eklund Foreliggande uppfinning avser en anordning for uppsamling och borttransport av stoft, rok och gaser vid valsverk, vilken anordning bestar av tvenne pa var sin sida om valsstolen anbragta suglador, vilka fOrmedelst rorledningen a.ro anslutna till gemensam utsugnings flakt. Inventor: T Eklund The present invention relates to a device for collecting and transporting dust, smoke and gases at rolling mills, which device consists of two suction ladles arranged on either side of the rolling mill, which are connected by means of the pipe to a common extraction surface.
Sam ett led i tidens allmanna stravan till bathe och mera hygieniska arbetsforhallanden mom industrien ha liven anordningar av ovannamnda slag pa senaste tiden i nagra fall kommit till anvandning. Det har emellertid visat sig svart att M en effektiv och andamalsenlig utsugning utan att anvanda sugkapor av sadana dimensioner eller med skimn placering att de forsva.ra valsstolarnas betjaning och tillsyn. As part of the general struggle of the time for baths and more hygienic working conditions in the industry, living devices of the above-mentioned types have recently in some cases come into use. However, it has been found to be effective and expedient extraction without the use of suction cups of such dimensions or with the apparent location of the operation and supervision of the wheelchairs.
Uppfinningen, som avser att eleminera ovannamnda svarigheter och mojliggOra ett allmannare utnyttjande av dylika utsugningsanordningar, kannetecknas av att sugladoma a.ro anbragta omedelbart over valsbanan och forsedda med en mot valsbanan vand utsugningsspalt, samt att i grenledningen fran vardera sugladan är anbragt ett avstangningsspj all, vilka spj all aro anordnade att automatiskt omstallas formedelst impulser fran valsstolens drift pli sadant satt att spjallet for den suglada som for tillfallet befinner sig pa valsstolens uttagssida alltid är oppet, medan det andra spjallet samtidigt ar stangt. The invention, which is intended to eliminate the above-mentioned responsibilities and enable a more general use of such extraction devices, can be characterized in that the suction cups a.ro are arranged immediately over the roller web and are provided with a suction gap facing the roller web, and in the branch line from each suction of which dampers are all arranged to be automatically adjusted by means of impulses from the operation of the roller chair in such a way that the damper for the suction cup which is incidentally on the outlet side of the roller seat is always open, while the other damper is closed at the same time.
Genom att sedan ordna utsugningen omedelbart intill de stallen dar rokutvecklingen i huvudsak sker kunna gaserna effektivt avlagsnas med anvandande av relativt sma luftmangder och sugla.dorna pa sa satt ges lampliga dimensioner sa att de ej stora driften. Tack vare att utsugningen endast sker pa en sida i taget blir den erforderliga flakten liten och sa blir aven i forekommande fall den anvanda stoftavskiljaren, varigenom anlaggningen som helhet blir enkel och prisbillig samti- Dupl. kl. 7 a: 27/03 digt som den kraver litet platsutrymme och arbetar effektivt. By then arranging the extraction immediately next to the stalls where the smoke development mainly takes place, the gases can be efficiently deposited using relatively small amounts of air and the columns in such a way that suitable dimensions are given so that they do not have large operations. Thanks to the fact that the extraction only takes place on one side at a time, the required space becomes small and so does the used dust separator, where applicable, so that the installation as a whole becomes simple and inexpensive at the same time. at 7 a: 27/03 poem as it requires little space and works efficiently.
Enligt en andamalsenlig utforingsform av uppfinningen aro sugladorna hopbyggda med utsugningsledningama formedelst vid aystrykamas svangningscentra anbragta bojliga slangar. Utsugningssystemet forses lampligen med en stoftavskilj are av i och fOr sig kant utforande. According to a spiritually embodied embodiment of the invention, the suction ladders are assembled with the suction lines formed by flexible hoses arranged at the oscillation centers of the aystricks. The extraction system is suitably provided with a dust separator of in and of itself edge design.
Uppfinningen skall nu narmare beskrivas i anslutning till bifogade ritning, som visar en exemplifierande utforingsform av uppfinningen. The invention will now be described in more detail in connection with the accompanying drawing, which shows an exemplary embodiment of the invention.
Pa ritningen betecknar 1 en valsstol och 2 och 3 tvenne pa var sin sida om valsstolen anbragta suglador, vilka formedelst grenledningar 4 och 5 och en stamledning 6 aro anslutna till en pa ritningen icke visad utsugningsflakt och ev. stoftavskilj are. Sugladorna aro enligt uppfinningen anbragta omedelbart Over valsbanan 7 och forsedda med en mot valsbanan vand utsugningsspalt 8 och 9 resp. I det visade fallet aro sugladorna hopbyggda med valsstolens avstrykare 10 och 11 och Mrbundna med utsugningsledningarna 4 och 5 formedelst bojliga slangar 4a och 5a anslutna till sugladorna vid avstrykarnas svangningscentra 12 och 13. Med 14 och 15 betecknas tvenne pneumatiska lyftanordningar for installning och upplyftning av namnda avstrykare och de med dem hopbyggda sugladorna. For att med en begransad luftmangd fa en effektiv utsugning sker enligt uppfinningen utsugningen endast genom den suglada som for tillfallet befinner sig pa valsstolens uttagssida. Sugladornas vaxelvisa inkoppling sker forme-deist i grenledningarna insatta avstangningsspjall 16 och 17. Spjallen aro anordnade att automatiskt omstallas formedelst impulser fran valsstolens drift, vilka impulser i det visade fallet styra en pneumatisk omstallningsanordning 18. Spjallbladen Oro inbordes for- 2— — stallda 900 sâ att det ena spjallet är stangt medan det andra ar Oppet. Utan frangaende av uppfinningens ide är det dock lampligt att utf8ra spjallen sa att de i stangt [age tillata en liten mangd luft att passera for att fh en svag utsugning aven pa valsstolens intagssida. In the drawing, 1 denotes a roller chair and 2 and 3 two suction ladles arranged on each side of the roller chair, which by means of branch lines 4 and 5 and a trunk line 6 are connected to a suction plane not shown in the drawing and possibly dust separators are. According to the invention, the suction ladders are arranged immediately over the roller web 7 and are provided with a suction gap 8 and 9, respectively, facing the roller web. In the case shown, the suction cups are assembled with the roller chair's wipers 10 and 11 and connected to the extraction lines 4 and 5 by means of flexible hoses 4a and 5a connected to the suction cups at the swivel centers 12 and 13 of the wipers. wipers and the sugars built with them. In order to obtain an effective extraction with a limited amount of air, according to the invention the extraction takes place only through the suction cup which is incidentally located on the outlet side of the roller chair. The alternating connection of the columns takes place in the form of shut-off slats 16 and 17. The slats are arranged to be automatically adjusted by means of impulses from the operation of the roller chair, which impulses in the case shown control a pneumatic adjustment device 18. The slat blades are mounted. that one damper is closed while the other is Open. Without departing from the spirit of the invention, however, it is feasible to make the slats so that they allow a small amount of air to pass in a rod to obtain a weak extraction even on the intake side of the roller chair.
