APPARATUS FOR AUTOMATICALLY CONTROLLING TRANSFER AMOUNT OF AIR FORCE FEED TYPE SEDIMENT TRANSFER APPARATUS

摘要

PURPOSE:To prevent a transport pipe from being clogged and enable automatic adjustment of flow rate by a method wherein at least pressure of compressed air for feeding to a compressor tank is automatically adjusted by static pressure in the transport pipe. CONSTITUTION:Signals related to static pressure P2 in a transport pipe 5 and static pressure P1 in a compressor tank 1 are input to a CPU 9. The CPU 9 operates an electricity-air converter 8 by these input signals to adjust a pressure adjust valve 13 automatically by controlled air Ac. Then amount of compressed air Ap in an air jet line 15 so that pressure difference between the static pressure P2 in the transport pipe 5 and the static pressure P1 in the compressor tank 1 is a specified value. This constitution can prevent the transport pipe from being clogged and enable smooth transportation.
