Abstract

Pieces of profiled, flexible mesh material are welded together to form a self-supporting segment with radial direction channels. The filter segment for a rotary disc filter comprises two or more pieces of flexible mesh material, each of which is profiled w.r.t. the segment radial direction. The profiles combine to form radial direction channels when the pieces of mesh material are welded together to form a self-supporting segment.

Description

521 492 ökande tvärsnittsarea. 521 492 increasing cross-sectional area.

Fördelen med denna uppfinning är radiellt riktade kanaler som underlättar flödet och ger en jämn massaavtagning att kanalerna kan ges en ökad utströmningsarea anpassad för det mot foten ökande flödet att ett nät ger större kapacitet och saknar i sig brottanvisningar att ge ökad valmöjligheten mellan olika nättyper och att dukbyten elimineras och att veckad filteryta ger större filteryta och bättre kapacitet.The advantage of this invention is radially directed channels which facilitate the fate and give an even mass reduction that the channels can be given an increased outflow area adapted to the flow increasing towards the foot that a net gives greater capacity and lacks breaking instructions to give increased choice between different net types and that cloth changes are eliminated and that pleated filter surface provides larger filter surface and better capacity.

10 15 20 25 30 35 521 492 Patentkrav10 15 20 25 30 35 521 492 Patent claims 1. Filtersektor, att nyttjas i exempelvis en av flera sådana till ett roterande skivfilter sammansatt enhet, k ä n n e t e c k n a d av att den är uppbyggd av åtminstone två nät, vilka vart och ett är något flexibelt, att vart nät är profilerat, sett väsentligen i nämnda filtersektors radiella riktning, att nämnda åtminstone två näts radiella profileringar är så inbördes orienterade att de mellan sig bildar huvudsakligen radiellt riktade kanaler och att nämnda åtminstone två nät är inbördes fogade så samman att en egenstyv filtersektor blir skapad.Filter sector, to be used in, for example, one of several such units assembled into a rotating disc filter, characterized in that it is built up of at least two nets, each of which is somewhat visible, that each net is profiled, seen essentially in said radial direction of the filter sector, that the radial profiles of the at least two nets are so mutually oriented that they form substantially radially directed channels between them and that the at least two nets are mutually joined so that a rigid filter sector is created. 2. Filtersektor enligt krav 1, k ä n n e t e c k n a d av att ett ytterligare nät, en hålförsedd eller hel skiva är lokaliserad mellan sagda åtminstone två nät och är sammanfogad med sistnämnda.Filter sector according to claim 1, characterized in that an additional net, a perforated or complete disc is located between said at least two nets and is joined to the latter. 3. Filtersektor enligt krav 1 eller 2, k ä n n e t e c k n a d av att nämnda åtminstone två nät är tillverkade av metall.Filter sector according to claim 1 or 2, characterized in that said at least two nets are made of metal. 4. Filtersektor enligt något av föregående krav , k ä n n e t e c k n a d av att vart nät är profilerat över hela sin yta.Filter sector according to one of the preceding claims, characterized in that each network is profiled over its entire surface. 5. Piltersektor enligt något av föregående krav, k ä n n e t e c k n a d av att nämnda profilering innefattar mjukt formade åsar och dalar.Pillar sector according to any one of the preceding claims, characterized in that said profiling comprises softly shaped ridges and valleys. 6. Filtersektor enligt krav 5, k ä n n e t e c k n a d av att nämnda åtminstone två näts dalar är riktade mot varandra och att nämnda sammanfogning är utförd mellan sagda åtminstone två näts dalar, i förekommande fall via sagda ytterligare nät, via den hålförsedda skivan eller den hela skivan.Filter sector according to claim 5, characterized in that said valleys of at least two nets are directed towards each other and that said joining is performed between said valleys of at least two nets, if applicable via said additional nets, via the perforated disc or the whole disc .
