Description
447 044 av de rör som ar ingjutna i fiberblocken. Detta kräver dels stor nog- grannhet vid tillverkningen och uppsättningen av blocken och dels att man t.ex. vid utbyte av element inte förändrar dessas utseende på ett sådant satt att de inte längre passar på upphängningsanordningarna. 447 044 of the tubes embedded in the fiber blocks. This requires great care in the manufacture and set-up of the blocks and that e.g. when replacing elements do not change their appearance in such a way that they no longer fit on the suspension devices.
Föreliggande uppfinning syftar till att ge en enkel upphängning av _elementen med frihet att placera dessa var som helst på ugnsväggarna samtidigt som ovanstående problem elimineras. Uppfinningen kännetecknas av de särdrag som anges i patentkraven.The present invention aims to provide a simple suspension of the elements with the freedom to place them anywhere on the furnace walls while eliminating the above problems. The invention is characterized by the features stated in the claims.
I anslutning till bifogade figurer skall uppfinningen nedan närmare beskrivas genom några utföringsexempel.In connection with the accompanying figures, the invention will be described in more detail below by means of some embodiments.
Figur 1 visar några slingor av ett meanderformat motståndselement av metalltråd. Elementet är upphängt på upphängningsanordningar enligt uppfinningen.Figure 1 shows some loops of a meander-shaped resistance element of metal wire. The element is suspended on suspension devices according to the invention.
Figur 2 visar ett tvärsnitt genom en ugnsvägg där två element är upp- hängda i enlighet med uppfinningen.Figure 2 shows a cross section through an oven wall where two elements are suspended in accordance with the invention.
Figur 3 visar en föredragen utföringsform av en upphängningsanordning enligt uppfinningen. _ Figur 4 a-d visar tvärsnitt av olika profiler enligt uppfinningen.Figure 3 shows a preferred embodiment of a suspension device according to the invention. Figure 4 a-d shows cross-sections of different profiles according to the invention.
Figur 5 visar en utföringsform av upphängningsanordningen enligt figur 3 som är särskilt anpassad för element framställda av bandformat material.Figure 5 shows an embodiment of the suspension device according to Figure 3 which is specially adapted for elements made of strip-shaped material.
Det i figur 1 visade motståndselementet (1) är upphängt på ett antal upphängningsanordningar (2) som lämpligen kan utgöras av profiler av samma material som motståndselementet. Profilerna kan ges den utformning som visas i figur 3 och 4d. Utan föregående håltagning i fiberblocken kan sedan en sådan profil stickas in i blocket och utgöra upphängningsanord- _ ning för en meanderslinga. Profilen bör till åtminstone två tredjedelar av sin längd stickas in i fiberblocket. Utplaceringen av profilerna underlättas väsentligt av att dessa inte behöver placeras ut förrän ugnen byggts färdigt och elementen skall hängas på plats. Man kan då använda de färdiga elementen som mall för instättning av profilerna. Det är lämpligt att profilerna sticks in i väggen i ca 45” vinkel mot horisontalplanet så som framgår av figur 2. I figur 2 visas 2 profiler (2) som bär upp var sitt element (l). Profilerna är instuckna i fiherblock (3) som bildar innervägg i en ugn. Ugnsväggen är dessutom försedd med ytterligare isolering (4) och en yttervägg (5) av plåt.The resistance element (1) shown in Figure 1 is suspended on a number of suspension devices (2) which can suitably be made of profiles of the same material as the resistance element. The profiles can be given the design shown in Figures 3 and 4d. Without prior drilling in the fiber blocks, such a profile can then be inserted into the block and constitute a suspension device for a meander loop. The profile should be inserted into the fiber block to at least two thirds of its length. The placement of the profiles is significantly facilitated by the fact that these do not need to be placed out until the oven has been completed and the elements are to be hung in place. You can then use the finished elements as a template for setting the profiles. It is suitable for the profiles to be inserted into the wall at an angle of approx. 45 ”to the horizontal plane as shown in Figure 2. Figure 2 shows 2 profiles (2), each supporting its own element (1). The profiles are inserted in fiber blocks (3) which form the inner wall of an oven. The oven wall is also provided with additional insulation (4) and an outer wall (5) of sheet metal.
Många utföringsformer av uppfinningen är tänkbara med hänsyn till de aktuella användningarna. T.ex. kan profiler utformas med olika tvärsnitt såsom visas i figur 4 a-d. För att samtidigt uppnå tillräcklig bärförmåga för elementen och fördelning av belastningen på fiberblocket bör profilen vara sådan att ytterkanterna höjts minst 60” från varandra dvs. den vinkel som i figur 4a markerats med vi skall vara minst 60°. I den föredragna utföringsform som visas i figur 4d bör vinkeln vz vara ca 120° vilket motsvarar att ytterkanterna böjts 60° från varandra. ~ vs-r-Hfffffl nrfßfi '_ . ...slå '_ w0äa~ .« n, *r ' 447 044 F19 5 vzsar en utföringsform av uppfinnxngen som är anpassad tlll element av bandformat material. Pâ en profil (2) är fäst, Lex. genom svetsning, en brygga (6). Profllen är instucken 1 ett av de fiherhlock (3) som utgör ugnsvagg varefter motståndselementet (1) hängs på och bars upp av bryggan.Many embodiments of the invention are conceivable in view of the present uses. For example. profiles can be designed with different cross-sections as shown in figure 4 a-d. In order to simultaneously achieve sufficient load-bearing capacity for the elements and distribution of the load on the fiber block, the profile should be such that the outer edges are raised at least 60 ”from each other, ie. the angle marked in figure 4a with vi shall be at least 60 °. In the preferred embodiment shown in Figure 4d, the angle vz should be about 120 °, which corresponds to the outer edges being bent 60 ° apart. ~ vs-r-Hffff fl nrfß fi '_. ... b '' w0äa ~. «n, * r '447 044 F19 5 shows an embodiment of the invention which is adapted to elements of strip-shaped material. Attached to a profile (2), Lex. by welding, a bridge (6). The profile is inserted into one of the fiber caps (3) which form the oven cradle, after which the resistance element (1) is hung on and carried by the bridge.
