Abstract

The invention relates to a press roller (1) comprising a stationary support and a rotary roller sleeve which is supported via at least one supporting element (press shoe, 4) that can be pressed thereagainst. Points for supplying liquid coolant and/or lubricant are provided within the supporting area. Sintered metals (5) are provided within the supporting element (4) so as to distribute the liquid coolant and/or lubricant.

Description

528 057* 2 vi pressko 4 och ställer in kyl- och smörjvätskan pà det nödvändiga trycket över sintrad metall 5. 528 057 * 2 vi press shoe 4 and sets the coolant and lubricant to the required pressure over sintered metal 5.

Fig. 3 visar en dubbelskopress, d.v.s. motvalsen består här likaså av en skovals 8.Fig. 3 shows a double shoe press, i.e. the counter-roller here also consists of a shoe roller 8.

Funktionssättet motsvarar den tidigare beskrivna varianten. Man kan här se, att presskon 4a hos den övre pressvalsen är stationär, medan anpressningstrycket genom anpressningscylindern 7 sker på presskon 4b hos den undre skovalsen 1. Genom denna I variant uppnås en längre presspalt och följaktligen en bättre och skonsammare awattning.The mode of operation corresponds to the previously described variant. It can be seen here that the press cone 4a of the upper press roll is stationary, while the pressing pressure through the pressing cylinder 7 takes place on the press cone 4b of the lower shoe roll 1. Through this variant a longer press gap is achieved and consequently a better and gentler dewatering.

Vidare har denna anordning fördelen, att pressmanteln inte utsätts lika hårt för växelböjning som vid traditionella skopressar. Drlften av pressen sker över pressväven(arna).Furthermore, this device has the advantage that the press jacket is not subjected to gear bending as hard as with traditional shoe presses. The pressure of the press takes place over the press fabric (s).

Fig. 4 visar ett alternativt anpressningssystem, varvid här det nödvändiga linjetrycket inte påförs över anpressningscylinder utan över en hydraulik- eller pneumatikslang 6 över hela afoetsbredden hos presskon 4c. |/.\n..n-_ua4n xaafu nnn-nnusnfunsu. _ _. _ lFig. 4 shows an alternative pressing system, in which case the necessary line pressure is not applied over the pressing cylinder but over a hydraulic or pneumatic hose 6 over the entire width of the press cone 4c. | /. \ n..n-_ua4n xaafu nnn-nnusnfunsu. _ _. _ l
