Description
Riffelplate for filterpresser. Rifle plate for filter presses.
Denne oppfinnelse vedrører riffelplater for slike filterpresser hvis elementer består vekselvis av rammer og riffelplater, hvorav de sistnevnte består av elastisk materiale, såsom gummi, og inneholder et me-tallforsterkningsinnlegg, og er belagt med en filterduk. Riffelplater av denne art har ikke de ulemper som kleber ved de riffelplater som i alminnelighet lages av pitch-pinetre, som man nødvendigvis må frem-stille med temmelig stor veggtykkelse. Som følge av den store veggtykkelse på de riffelplater som består av treverk, er den plass som kreves for pressen, lite utnyttet. Disse riffelplater er temmelig stive; herved får man dårlig avtetting av de plater og rammer som ligger mot hverandre. Med hen-blikk herpå har man sett seg nødsaget til å bruke to filterduker istedetfor bare én filterduk, idet den annen filterduk vesent-lig tjener som tettingsmiddel. This invention relates to fluted plates for such filter presses whose elements consist alternately of frames and fluted plates, the latter of which consist of elastic material, such as rubber, and contain a metal reinforcement insert, and are coated with a filter cloth. Rifled boards of this kind do not have the disadvantages associated with the rifled boards that are generally made from pitch pine, which must necessarily be produced with a fairly large wall thickness. As a result of the large wall thickness of the corrugated plates which consist of wood, the space required for the press is little utilised. These rifle plates are fairly stiff; this results in poor sealing of the boards and frames that lie against each other. With this in mind, it has been necessary to use two filter cloths instead of just one filter cloth, as the other filter cloth essentially serves as a sealing agent.
Dersom det er mulig å utføre riffelplatene tynnere, kan det på den samme plass som pressen hittil har krevet, plaseres et større antall plater og rammer. En min-sking av veggtykkelsen betyr imidlertid, at riffelplatene under slike påkjenninger som for eksempel opptrer ved forstoppelse av kammertilførselsåpningene, står i fare for å brytes i stykker. Selv ved de tykkveggete pitchpine-riffelplatene er det ikke sjelden at disse brister. If it is possible to make the corrugated plates thinner, a larger number of plates and frames can be placed in the same space that the press has so far required. A reduction in the wall thickness means, however, that the rifled plates are in danger of breaking into pieces under such stresses as, for example, occur when the chamber supply openings are blocked. Even with the thick-walled pitchpine riffle plates, it is not uncommon for these to crack.
Ifølge oppfinnelsen dannes forsterk-ningsinnlegget for riffelplatene av et gitter av sammensveisete, bøyningsstive elementer, som er dimensjonert slik at gitteret under de påkjenninger som opptrer ved til-stopping av kammertilføringene, kan underkastes en elastisk deformasjon, som for å avstøtte den utbøyete del av riffelplaten, går hen til den neste riffelplate. According to the invention, the reinforcement insert for the rifled plates is formed by a grid of welded together, bending-rigid elements, which are dimensioned so that the grid, under the stresses that occur when the chamber feeds are blocked, can be subjected to an elastic deformation, as if to support the bent part of the rifled plate , goes to the next rifle plate.
Den nye riffelplate kan takket være denne deformasjonsmulighet og avstøtting utføres med betraktelig mindre veggtykkelse enn vanlig. Thanks to this possibility of deformation and repulsion, the new rifle plate can be made with considerably less wall thickness than usual.
Forsterkningsgitteret strekker seg for-trinnsvis bare over riffelplatens midtparti, omtrent svarende til høyden på rammeåp-ningen, idet dette er det område hvori ut-bøyningene kan skje i noen nevneverdig ut-strekning. The reinforcing grid preferably extends only over the central part of the rifled plate, approximately corresponding to the height of the frame opening, as this is the area in which the deflections can occur to any significant extent.
Dimensjonene for røret eller profilet som danner gitteret, er bare omtrent lik halvparten av riffelplatenes veggtykkelse. Som følge herav er de elastiske sjikt av ma-terialet tilstrekkelig tykke til å sikre en god avtetting også i området for gitteret. The dimensions of the tube or profile forming the grating are only approximately equal to half the wall thickness of the corrugated plates. As a result, the elastic layers of the material are sufficiently thick to ensure a good seal also in the area of the grid.
Det elastiske materiale, som filterpres-sebestykkingen kan være fremstilt av, kan The elastic material, from which the filter press piece can be made, can
være mykgummi. Når det materiale som skal filtreres for eksempel inneholder be-stemte kjemikalier eller oljer, bruker man istedetfor gummi plaststoffer, innbefattet be soft rubber. When the material to be filtered, for example, contains certain chemicals or oils, rubber plastics are used instead, including
de syntetiske gummiarter. For eksempel kan klorsulfonert polyetylen komme i be-traktning. the synthetic rubber species. For example, chlorosulfonated polyethylene can be considered.
