The utility model relates to the technical field of IBC (
Intermediate Bulk Container) liquid drainage, and discloses an auxiliary liquid drainage structure of an IBC (
Intermediate Bulk Container), which comprises an inner container body and a
metal frame sleeved outside the inner container body, a supporting disc is arranged outside the top of the inner container body, and clamping components are connected to two sides of the supporting disc. A supporting sleeve plate, a supporting cylinder, a
bevel gear box and a guide cylinder are arranged in the inner container body in a sleeved mode. According to the utility model, the guide cylinder, the
spiral blade shaft, the
bevel gear box, the supporting sleeve plate, the supporting cylinder and the adjusting shaft are matched with the drain valve
pipe and the inner container body for
combined use; the
bevel gear box, the guide cylinder and the
spiral blade shaft can rotate to give way on the inner side of the bottom of the inner container body and enable the guide cylinder to be aligned with the liquid discharging valve
pipe, and then along with reciprocating output of the adjusting shaft to the
spiral blade shaft through the bevel gear box, raw materials are conveyed into the liquid discharging valve
pipe in an accelerated mode in a spiral
extrusion conveying mode. And the material conveying speed of the drain valve pipe is accelerated.
