20 Feet bulk cement container tank

Basic configuration of powder tank: 2 DN500 quick-open manholes, 2 DN100 ash outlet valves, 4 DN50 air inlet valves, 1 safety valve, 1 pressure gauge, 1 pressure discharge valve, secondary air inlet device, air bag liquefaction bed (V-type two-bin type), ash outlet air inlet pipeline, etc.

The tank has a double cone, inward-tilting horizontal structure, with two bins for simultaneous air intake and discharge, and two bins for simultaneous charging.

1. Connect the discharging pipe to ensure reliable sealing
2. Close the discharge valve, external wind valve and secondary wind valve.
3. Connect the air inlet pipe to ensure reliable sealing; open the air inlet valve, turn on the external air source and inflate the air chamber in the tank; when the pressure in the tank - i.e. the pressure gauge reading reaches 2 BAR, open the discharge valve (if the pressure continues to rise, it means the pipe is blocked). The discharge pressure should be maintained between 1.8 and 2.4 BAR. When unloading is complete and the pressure in the tank drops to 0.2 BAR, open the secondary air ball valve so that the ash unloading pipeline is all unblocked.
4. Turn off the air source after unloading; open the pressure discharge valve to discharge the pressure inside the tank.
