Abstract
Description
15 20 25 30 35 512 847. 15 20 25 30 35 512 847.
Närmare bestämt kännetecknas pressen enligt uppfinningen av det som anförs i patentkravet 1. Fördelaktlga utföringsformer av uppfinningen anförs i de övriga kraven.More specifically, the press according to the invention is characterized by what is stated in claim 1. Advantageous embodiments of the invention are stated in the other claims.
Den främsta fördelen med uppfinningen är att inmatningen kan anordnas effektivt även med stora materialflöden. Vid trummans slutände kan materialet likväl komprimeras till en så tunn matta som möjligt och sålunda kan man uppnå en maximal torrämnes- halt. För att uppnå dessa fördelar behöver anordningens storlek eller vikt emellertid inte ökas.The main advantage of the invention is that the feed can be arranged efficiently even with large material flows. At the end of the drum, the material can nevertheless be compressed into as thin a mat as possible and thus a maximum dry matter content can be achieved. To achieve these benefits, however, the size or weight of the device need not be increased.
Pressen enligt uppfinningen kan framför allt användas för avvatt- ning av vattenhaltigt material. Typiska användningsobjekt är pressning av bark, slam från reningsverk, cellulosa eller torv. l det följande beskrivs vissa fördelaktiga utföringsformer av upp- finningen närmare med hänvisning till bifogade ritningar. l dessa illustrerar figur 1 trumpressen sedd från sidan och figur 2 en an- nan trumpress sedd från sidan.The press according to the invention can above all be used for dewatering aqueous material. Typical objects of use are pressing of bark, sludge from sewage treatment plants, cellulose or peat. In the following, certain advantageous embodiments of the invention are described in more detail with reference to the accompanying drawings. In these, Figure 1 illustrates the drum press seen from the side and Figure 2 another drum press seen from the side.
Huvudkomponenterna i pressen är en roterande trumma 1 och en pressvals 2 som roterar inne i denna. Trumman har hål, genom vilka vätska avlägsnas från materialet 3 som skall pressas. Val- sen kan även utformas ihålig och perforerad, varvid vätska av- lägsnas även via valsen. Materialet inmatas i trummans främre ände 4. Det cirkulerar flera varv i trumman och avlägsnas via trummans bakre ände 5. Trumman kan användas exempelvis för avvattning av fuktig bark.The main components of the press are a rotating drum 1 and a press roller 2 which rotates inside it. The drum has holes through which liquid is removed from the material 3 to be pressed. The roller can also be designed hollow and perforated, whereby liquid is also removed via the roller. The material is fed into the front end of the drum 4. It circulates several turns in the drum and is removed via the rear end of the drum 5. The drum can be used, for example, for dewatering moist bark.
Valsens 2 axel 6 är så lagrad att valsens främre ände 7 och bakre ände 8 kan lyftas och sänkas oberoende av varandra.The shaft 6 of the roller 2 is so mounted that the front end 7 and the rear end 8 of the roller can be lifted and lowered independently of each other.
Helst är ändarna lagrade flytande t.ex. med hjälp av en hydrau- lisk cylinder så att valsen pressar materialet med konstant tryck oberoende av materialskiktets tjocklek.Preferably, the ends are stored floating e.g. by means of a hydraulic cylinder so that the roller presses the material at a constant pressure regardless of the thickness of the material layer.
Trumpressen kan vara sådan att antingen endast valsen, eller både valsen och trumman, eller endast trumman roteras. Kraft- 10 15 20 25 30 35 512 847 överföringen kan åstadkommas på önskat sätt. Teknik som till- låmpas i trumpressar har beskrivits t.ex. i patentskrifterna Fl- 69207 och Fl-90442.The drum press can be such that either only the roller, or both the roller and the drum, or only the drum is rotated. The power transmission can be accomplished in the desired manner. Techniques applied in drum presses have been described e.g. in patents F1- 69207 and F1-90442.
Främre änden 7 av valsen 2 har en mindre diameter än valsens bakre ände 8.The front end 7 of the roller 2 has a smaller diameter than the rear end 8 of the roller.
Till en början kan valsen 2 regleras t.ex. med ett stopporgan i ett sådant läge att den inte berör trumman 1. Då man börjar inmata material 3 i trummans främre ände 4, lyfter detta valsens främre ände 7 då det hamnar mellan trumman och valsen. Då materialet framskrider lyfter det även valsens bakre ände 8. Mellan trum- man och valsen bildar materialflödet en kilformad materialmatta 9, som avlägsnas vid trummans slutände. Materialets framskri- dande kan påverkas med hjälp av trummans lutningsvinkel eller avböjningsplattor.Initially, the roller 2 can be adjusted e.g. with a stop means in such a position that it does not touch the drum 1. When one begins to feed material 3 into the front end 4 of the drum, this lifts the front end 7 of the roller when it ends up between the drum and the roller. As the material progresses, it also lifts the rear end 8 of the roller. Between the drum and the roller, the material flow forms a wedge-shaped material mat 9, which is removed at the end of the drum. The progress of the material can be influenced by the angle of inclination of the drum or deflection plates.
Vid trummans 1 främre ände 4 finns rikligt med utrymme ovanför valsen 2, så att lnmatningen år lätt att ordna. lnmatningen sker även pålitligt, så även de största materialstyckena väl ryms in genom den stora inmatingsmynnlngen.At the front end 4 of the drum 1 there is plenty of space above the roller 2, so that the feed is easy to arrange. The feed is also reliable, so that even the largest pieces of material fit well through the large feed mouth.
Vid främre änden 4 av trumman 1 finns även rikligt med utrymme under valsen, varvid mattan 9 kan vara relativt tjock vid sin främre ände jämfört med bakre änden. Sålunda kan t.ex. även ett stort materialflöde komprimeras till en hög torrämneshalt. Val- sens lutningsvinkel är trots detta mycket nära sitt grundläge, vil- ket underlättar lagringsarrangemanget. Valsen har likväl relativt stora rörelsetoleranser.At the front end 4 of the drum 1 there is also plenty of space under the roller, whereby the mat 9 can be relatively thick at its front end compared to the rear end. Thus, e.g. even a large flow of material is compressed to a high dry matter content. The angle of inclination of the roller is nevertheless very close to its basic position, which facilitates the storage arrangement. The roller still has relatively large movement tolerances.
Tilläggsutrymmet i trummans 1 främre ände 4 minskar även sli- tage, då en tjock matta av t.ex. sandig bark inte är i häftig berö- ring mot komponenterna ovanför valsen. Även slitaget av matar- anordningen minskar då man inte behöver mata in materialet i trumman med stor kraft. 10 512 847.The additional space in the front end 4 of the drum 1 also reduces wear, as a thick mat of e.g. sandy bark is not in violent contact with the components above the roller. The wear of the feeder device is also reduced as it is not necessary to feed the material into the drum with great force. 10,512,847.
I trumpressen enligt figur 2 har valsens 2' främre ände 7' kon- stant diameter, som sedan växer stegvis vid punkt 10 och äter blir konstant vid bakre änden 8”. Sålunda ändras även material- mattans 9' tjocklek stegvis. Vid behov kan det finnas flera steg.In the drum press according to Figure 2, the front end 7 'of the roller 2' has a constant diameter, which then grows stepwise at point 10 and eats constantly at the rear end 8 '. Thus, the thickness of the material mat 9 'also changes stepwise. If necessary, there may be several steps.
Ett stegvis föränderligt mellanrum mellan trumman och valsen blir aktuellt i tillämpningar där man önskar utföra pressningar i olika steg under markerat olika tryck. Ett exempel på en sådan till- lämpning kunde vara massatvätt. En tvättmetod har beskrivits t.ex. i patentskrift Fl-90442 (motsvarar patentansökan PCT/Fl93lO0452).A stepwise changing space between the drum and the roller becomes relevant in applications where it is desired to perform pressing in different steps under markedly different pressures. An example of such an application could be mass washing. A washing method has been described e.g. in patent specification F1-90442 (corresponds to patent application PCT / Fl93100452).
Uppfinningen kan även utföras t.ex. så att trummans diameter är större vid främre änden än vid slutänden.The invention can also be carried out e.g. so that the diameter of the drum is larger at the front end than at the end.
