Method and device for injecting a fluid in a medium which is a fluid behaviour and to the mechanical stirring, with the action of a declogging of this medium.

摘要

Injecting a fluid into a fluid medium for mechanical agitation. An extended flexible nozzle (11) in the vessel is fixed at one end (12) to a source (15) of fluid under pressure, and free at the discharge end (13). The fluid under pressure produces whipping movements of the nozzle to mix the medium and random movements of the discharge end to direct a fluid jet in various directions The pressure of the fluid fed to the nozzle is varied or the fluid is intermittent. The fluid is gas to ensure the fluidization of a powdered material. The nozzle is placed upstream of a sieve and supplied with gas to ensure that the material is agitated and the sieve vibrated whilst fluidizing the material and blowing it in the direction of the sieve. Device for carrying out the process and installation containing such a device, with the nozzle upstream or downstream of the sieve (for agitation or unblocking).
