Dobbelskruepresse.Twin screw press.

i Oppfinnelsen vedrører en dobbelskruepresse som benyt- i The invention relates to a twin-screw press that uses

tes for utpressing av væske fra materialer som inneholder væske,tested for the extraction of liquid from materials containing liquid,

og som innbefatter to parallelt med hverandre anordnede, roter-and which includes two arranged parallel to each other, rotating

Det finnes imidlertid visse materialer, f. eks. raigress og lucerne som er vanskelig å presse vannet ut av ved hjelp av konvensjonelle dobbelskruepresser, med mindre fiberstrukturen og de væskeinneholdende celler i .materialet først er brutt i stykker. Det er derfor vanlig å ha en hjelpe- are used in various process industries where they are completely satisfactory with regard to removing liquid from most liquid-containing materials. However, there are certain materials, e.g. ryegrass and lucerne, which are difficult to squeeze the water out of using conventional twin-screw presses, unless the fiber structure and the fluid-containing cells in the material are first broken into pieces. It is therefore common to have an auxiliary

Ifølge foreliggende oppfinnelse er det derfor tilveie-bragt en dobbelskruepresse av den innledningsvis nevnte type, According to the present invention, a double screw press of the initially mentioned type is therefore provided,

Den viste dobbelskruepresse bestar i hovedsaken av to aksler 10 og 11 som er montert slik at de forløper parallelt med hverandre. Akslene 10 og 11 er opplagret i ikke viste lagre slik at de kan dreies i de rotas-jonsretninger som er antydet med rotas j onspilene X og Y. Dreiingen av skruene skjer ved hjelp av ikke viste motorer. The twin screw press shown mainly consists of two shafts 10 and 11 which are mounted so that they run parallel to each other. The shafts 10 and 11 are stored in bearings not shown so that they can be rotated in the directions of rotation indicated by the rotation arrows X and Y. The rotation of the screws takes place with the help of motors not shown.

Akslene 10 og 11 er hver forsynt med en kontinuerlig skrueformet skovle henholdsvis 12 og 13- Skovlene griper i hverandre, slik det går frem av figurene. The shafts 10 and 11 are each provided with a continuous screw-shaped vane 12 and 13 respectively - The vanes engage each other, as can be seen from the figures.

De to på denne måten tilformede skruer omsluttes av et dreneringsbur som består av en perforert plate V-\. Buret er opplagret i en ramme 15- The two screws formed in this way are surrounded by a drainage cage consisting of a perforated plate V-\. The cage is stored in a frame 15-

Som det går frem av fig. 1 avtar stigningen til skovle-As can be seen from fig. 1 decreases the pitch to vane-

As the material passes through the press, the volume taken up by the material will be reduced, and liquid is thereby pressed out through the perforations in the cage 14.

I samsvar med oppfinnelsen er det på de skovlflaterIn accordance with the invention, it is on the blade surfaces

rom. Fremspringene befinner seg langs skovlkantene og de er for-trinnsvis større og har mindre avstand i den første del av dreneringsburet, og blir mindre og får større innbyrdes avstand i den resterende del av buret. I et.typisk utførelseseksempel for-synes to tredjedeler av skruelengden mellom innmatingskammeret og utløpsenden med fremspring. room. The protrusions are located along the blade edges and they are preferably larger and have a smaller distance in the first part of the drainage cage, and become smaller and have a greater mutual distance in the remaining part of the cage. In a typical design example, two-thirds of the screw length between the feed chamber and the outlet end is provided with projections.

I utførelseseksemplet er fremspringene utført ved atIn the design example, the protrusions are made by

de bakre endene til hakk 20 som er tatt ut i skovlkantene, er bøyet fremover, det vil si i retning mot pressens utløpsende. the rear ends of notches 20, which are taken out in the blade edges, are bent forward, that is to say in the direction towards the outlet end of the press.

Disse kantene som danner fremspringene, vil utføre en skjærende og rivende virkning på et' fibrøst eller celleformet materiale som føres aksialt gjennom pressen. These edges which form the protrusions will perform a cutting and tearing action on a fibrous or cellular material which is passed axially through the press.

Oppfinnelsen er naturligvis ikke begrenset til .det viste ut f ørelseseksermpel. Eksempelvis kan fremspringene tilveie-bringes ved at små deler fastsveises eller skrues fast på skov- The invention is of course not limited to the proven example. For example, the protrusions can be provided by small parts being welded or screwed onto the

lene, og man kan også tenke seg fremspringene dannet av boltho-der, idet boltene da f.eks. er skrudd inn i gjengehull i skovlene. Dreneringsburet kan også eksempelvis bestå av flere parallelt forløpende stenger istedenfor av en perforert plate. lean, and one can also imagine the protrusions formed by bolt heads, as the bolts then e.g. are screwed into threaded holes in the vanes. The drainage cage can also, for example, consist of several bars running in parallel instead of a perforated plate.
