The filter discs consist of filter sectors having surrounding filter cloth and internal channels and between the filter sectors and an outlet from the vessel (1) there is a connection in the central axle (2). Moreover, a scraper (7) is arranged for removing the filter cake (8) on the filter cloth obtained during the filtering operation and a vertical outlet pipe (12) receives the scraped-off filter cake material. The central axle (2) is formed with only one common channel for the filtrate and the gas from all filter sectors in the vessel (1) and consists of a tube.

    • A spray tube nozzle adapted to be cleaned during its operation. The nozzle includes a nozzle head having an inlet connectable to a conduit and an outlet for spraying liquid. Within the nozzle head is located a rotatable element defining a through-hole. The through-hole is shaped in such a way that the opening at one end is of relatively small cross-section and at the opposite end of a relatively large cross-section. The rotatable element is sealingly arranged in the nozzle head and has an external groove. The rotatable element can be positioned in at least a first rotational position to facilitate flow of spraying liquid from the conduit, to the nozzle inlet, and through the through-hole in the rotatable element, to the nozzle outlet for forming spray jets at the outlet. A second rotational position allows liquid to be flushed through the conduit by flow of the spraying liquid from the inlet, through the groove, and exiting the nozzle through a flush hole. A third rotational position allows the through-hole to be flushed by the flow of spraying liquid from the nozzle inlet through the through-hole in a second direction opposite to the first direction.
