Extruder hood for pneumatic transport system

摘要

An extruder bell (10) configured to operate in a stationary and / or non-stationary state configuration, said extruder bell (10) comprising: a bypass regulator (16) that includes an air inlet (18) ); and an extruder bell outlet (20); and a main bell body (12) including an extruder discharge zone (14) within an interior space of said extruder bell (10), said extruder discharge zone (14) being configured to receive extruded material, said extruder bell (10) being, in the steady state configuration, configured to direct the air received from said air inlet (18) through said extruder discharge zone (14) to cause the extruded material to be expelled of said extruder hood (10) through said extruder bell outlet (20), said extruder bell (10), in the non-stationary state configuration, configured to direct the air received from said air inlet ( 18) outside said extruder hood (10) through said extruder outlet (20) without being directed through said extruder discharge zone (14); and a distribution head (22) connected to said main bell body (12) at a second end of the main bell body (12), said bypass regulator (16) being configured to fluidly connect to said second end of the main bell body (12) through said distribution head (22), said distribution head (22) being characterized in that it comprises a pair of distribution arms (60, 62) configured to direct the air from said regulator of bypass (16) to said main bell body (12).
