A nozzle assembly for spraying a wash liquid towards a pulp mat, the assembly comprising:
- an integral fastener-nozzle having a conduit for the wash liquid, an outlet to the conduit for discharging the wash liquid and an attachment to secure the fastener-nozzle to an aperture in a wash liquid pipe, and
- a wash liquid direction device extending outwardly from the pipe and adapted to direct the wash liquid from the outlet towards the pulp mat.
An assembly for spraying a wash liquid onto a pulp mat comprising:
- a wash liquid pipe extending substantially parallel to the pulp mat and separated by a distance from the pulp mat, wherein the pipe includes a plurality of apertures for discharging wash liquid flowing through the pipe;
- a plurality of fasteners nozzle arranged along the wash liquid pipe and adapted to direct wash liquid towards the pulp mat;
- wherein the fasteners nozzle each comprise a hollow stem adapted to be inserted into one of said apertures in the pipe, and
- a wash liquid direction device extending outwardly from the pipe and adapted to direct the wash liquid from the outlet towards the pulp mat, wherein each wash liquid direction device is secured to the pipe by at least one fasteners nozzle.
A method to assemble a nozzle comprising:
- inserting a hollow stem of a fastener-nozzle through an aperture in a wash liquid direction device;
- attaching the fastener-nozzle to an aperture in a wash liquid pipe such that the hollow stem is in fluid communication with a wash liquid passage in the pipe and the wash liquid direction device is between the pipe and a head of the stem, and
- securing the fastener-nozzle to the pipe such that the wash liquid direction device is fixed with respect to the pipe by securing the fastener-nozzle.
