Pop-up nozzle, cleaning device and method of operation

摘要

A nozzle for cleaning-in-place of a vessel has a nozzle body to be connected to a wall of the vessel and defining an opening, a nozzle insert is contained within the nozzle body and is able to assume at least two distinct positions relative to the nozzle body, a first position in which the nozzle insert is retracted into the nozzle body and a second position in which the nozzle insert is advanced in the axial direction relative to the nozzle body and protrudes into the vessel. Apertures are exposed in the second position to allow distribution of a cleaning fluid. The nozzle insert has two nozzle insert parts, in mutual abutment in the first position and spaced from each other in a direction transverse to the axial direction in the second position to form a gap between adjacent nozzle insert parts, the apertures being exposed in the gap.

1. A nozzle for cleaning-in-place of a vessel, comprising a nozzle body adapted to be connected to a wall of the vessel and defining an opening, and a nozzle insert contained within the nozzle body, the nozzle insert having an axial direction and being adapted to assume at least two distinct positions relative to the nozzle body, of which in a first position, the nozzle insert is retracted into the nozzle body and a front end of the nozzle insert is substantially flush with a front end of the nozzle body, and in a second position, the nozzle insert is advanced in said axial direction relative to the nozzle body and is adapted to protrude into the vessel, a plurality of apertures being exposed in said second position to allow distribution of a cleaning fluid, characterized in that said nozzle insert comprises at least two nozzle insert parts, and that said nozzle insert parts are in mutual abutment in the first position and spaced from each other in a direction transverse to said axial direction in the second position to form at least one gap between adjacent nozzle insert parts, said apertures being exposed in said gap.
