Description
504 097 2 till bifogade ritning, som schematiskt visar några utföringsexempel på filteranordningar enligt uppfinningen, och på vilken figur l är en perspektivvy av en filteranordning enligt en första utföringsform, figur 2 är en planvy av filtret i en ventilationskanal visad i längsektion, figur 3 är en perspektivvy av en filteranordning enligt en andra utföringsfonn, figur 4 är en planvy av filtret i figur 3 i en ventilationskanal visad i längsektion, och figur 5 är en perspektivvy av en filteranordning enligt en tredje utföringsform. 504 097 2 to the accompanying drawing, which schematically shows some embodiments of filter devices according to the invention, and in which figure 1 is a perspective view of a filter device according to a first embodiment, figure 2 is a plan view of the filter in a ventilation duct shown in longitudinal section, figure 3 is a perspective view of a filter device according to a second embodiment, figure 4 is a plan view of the filter of figure 3 in a ventilation duct shown in longitudinal section, and figure 5 is a perspective view of a filter device according to a third embodiment.
Den i fig.l visade utföringsformen av filteranordningen är tillverkad av ett förhållandevis tjockväggigt filtermaterial och har formen av ett L med en rörformig inloppsdel l som övergår i en sidoriktad utloppsdel 2 med en av filtermaterialet bestående, sluten änddel 3.The embodiment of the filter device shown in Fig. 1 is made of a relatively thick-walled filter material and has the shape of an L with a tubular inlet part 1 which merges into a lateral outlet part 2 with a closed end part 3 consisting of the filter material.
Filteranordningen är, såsom visas i fig. 2, avsedd att införas i ventilationskanal 10, som vid en ände är försedd med en kort rörstuds ll.The filter device is, as shown in Fig. 2, intended to be inserted into ventilation duct 10, which at one end is provided with a short pipe connection 11.
Filteranordningen l,2,3 har något mindre diameter än ventilationskanalen 10 och rörstudsen ll, och inloppsdelens l öppna ändparti 4 är på lämpligt sätt tätande anbragt vid änden av en förminskningsmuff 12, exempelvis genom cnvikning runt muffens 12 ände och fastspänning medelst ett fästband 5.The filter device 1,2,3 has a slightly smaller diameter than the ventilation duct 10 and the pipe connection 11, and the open end portion 4 of the inlet part 1 is suitably sealed at the end of a reduction sleeve 12, for example by folding around the end of the sleeve 12 and clamping by means of a fastening band 5.
Filteranordningen l,2,3 bildar en strypning i ventilationskanalen 10 och rörstudsen ll när luft sugs in i ventilationskanalen, och genom det över filtrets väggar bildade tryckfallet konner filtrets rörformiga väggar 1,2 att sugas in och centreras i det i fig. 2 visade läget i ventilationskanalen 10 och rörstudsen ll. Ett gallerlock (ej visat) kan på brukligt sätt vara anbragt över öppningen 4.The filter device 1, 2,3 forms a throttle in the ventilation duct 10 and the pipe connection 11 when air is sucked into the ventilation duct, and due to the pressure drop formed over the walls of the filter, the tubular walls 1,2 of the filter can be sucked in and centered in the position shown in fig. in the ventilation duct 10 and the pipe connection ll. A grid lid (not shown) can be arranged over the opening 4 in the usual manner.
Filteranordningen kan även ha det i fig. 3 visade utförandet med en inloppsdel l och två i motsatta riktningar sidoriktade utloppsdelar 2 med slutna ändar 3. En sådan filteranordning är avsedd att insättas i en ventilationskanal 10 med en sidoriktad inloppsrörstuds ll, såsen visas i fig. 4. Om filtermateríalet vid åtminstone inloppsdelens 1 öppningsparti 4 är elastiskt kan detta krängas över rörstudsens ll ändparti och spännas fast medelst ett fästband. Alternativt kan inloppsdelens l öppningsparti 4 vara försedd med en manschett med en utvidgad del som passar till rörstudsens ändparti.The filter device may also have the embodiment shown in Fig. 3 with an inlet part 1 and two laterally directed outlet parts 2 with closed ends 3. Such a filter device is intended to be inserted into a ventilation duct 10 with a lateral inlet pipe connection 11, the sauce is shown in fig. 4. If the filter material at the opening portion 4 of at least the inlet part 1 is elastic, this can be tilted over the end portion of the pipe connection 11 and clamped by means of a fastening band. Alternatively, the opening portion 4 of the inlet part 1 may be provided with a sleeve with an enlarged part which fits into the end portion of the pipe connection.
En inloppsrörstuds kan vara placerad på andra ställen utmed en ventilationskanal, exempelvis vid ett rörknä. Då får filteranordningen det i fig. 5 visade utseendet med en inloppsdel l och två vinkelställda utloppsdelar 2 med slutna ändar 3. Även en tredje utloppsdel med sluten ände kan tänkas i förlängningen av de i fig. 5 visade utloppsdelarna 2 504 097 3 om filteranordningen är avsedd att insättas i ett på motsvarande sätt utformat hörnparti hos ett ventilationskanalsystem.An inlet pipe connection can be placed in other places along a ventilation duct, for example at a pipe knee. Then the filter device gets the appearance shown in Fig. 5 with an inlet part 1 and two angled outlet parts 2 with closed ends 3. A third outlet part with closed end is also conceivable in the extension of the outlet parts 2 shown in Fig. 5 if the filter device is intended to be inserted into a correspondingly designed corner portion of a ventilation duct system.
Uppfinningen är självfallet inte begränsad till de här visade och beskrivna utföringsexemplen utan kan modifieras på åtskilliga sätt immn ramen för den i patentkraven definierade uppfínningstanken. Detta gäller bl.a. vid speciella utföranden av ventilationskanalerna då form och diametrar eller areor hos inlopps- och utloppsdelar hos filteranordningarna måste anpassas till såväl ventilationskanalers sam rörstudsars form och diametrar eller areor.The invention is of course not limited to the exemplary embodiments shown and described here, but can be modified in several ways within the scope of the inventive concept defined in the claims. This applies i.a. in special embodiments of the ventilation ducts, when the shape and diameters or areas of the inlet and outlet parts of the filter devices must be adapted to the shape and diameters or areas of the ventilation ducts of the ducts.
