DOUBLE DAMPER TYPE CONTINUOUS-SUCTION PNEUMATIC TRANSPORT DEVICE

摘要

PROBLEM TO BE SOLVED: To improve powder transport capacity, by preventing sticking-deposition of powder on a bypass pipe, when pneumatically transporting fine powder such as carbon black, by using a double damper type continuous-suction pneumatic transport device having the bypass pipe.;SOLUTION: A filter 112 with a backwash mechanism 110 is arranged in the bypass pipe 90, and atmospheric pressure is applied to the filter 112 via a second bypass pipe 100 when opening a second damper module 20. A compressed air pulse is applied to the filter 112 by operating the backwash mechanism 110, and the filter is effectively washed back by increasing a pressure difference before and after the filter.;COPYRIGHT: (C)2010,JPO&INPIT
