The system is for the reception and transport of dry lime mud from a continuously operating pressurized filter in a causticization process. A tube valve is used as an outlet from the pressurized process. The tube valve has a minimum length that is twice a diameter of the tube. A column of lime mud can be held within it as a pressure lock. The column of lime mud can be caused to descend through the tube valve by controlling a difference in pressure between an inner surface and an outer surface of the tube such that the diameter of the tube expands essentially uniformly along its length by 5-10% or by at least 4-6 millimeters.

The arrangement is for the axial driving of a supply hose () for pressure medium or application medium in the form of fluid, gaseous or solid, granule-formed or powder-formed, material. The supply hose () is connected to a displaceable cartridge () provided with at least one spray nozzle (). The cartridge () is arranged in a guide tube () along an object that is to be sprayed. The arrangement has three driving wheels (), where at least one driving wheel () is driven by driving means and where each driving wheel () has a concave jacket surface () congruent with the supply hose (). The concave jacket surface () surrounds the supply hose to at least 100&#xb0; degrees of the circumference of the supply hose ().

The sealing device is for drum filters or filter presses to form a seal between the rotary drum end faces and the end faces of the trough in which the rotary drums are situated. A sealing element () is disposed in a groove () on the rotary drum end face, in which the sealing element () is pressed into contact against the opposite part by a hose element (), preferably in form of two flexible hoses (), which can be pressurized internally. The hoses () are disposed one on top of the other in the groove () beneath the sealing element (). The two open ends of the hose element () are provided with sleeves () which enclose the ends. The sleeves () are held in place in the groove () with a holder element (). Spaces () are formed on both sides of the middle piece () of the holder element. One space () is provided with an inlet () for pressurizing medium and the other space () is provided with an outlet () for the pressurizing medium. The sealing device also has a sleeve () and a holder element ().
