Bulk container and ventilation device thereof

摘要

Disclosed are a ventilation device of a bulk container and a bulk container comprising the same. The ventilation device comprises a ventilation pipe (1) and a one-way valve (2), wherein the ventilation pipe (1) is arranged on the body of the container, an air inlet thereof faces the outside of the body of the container, and an air outlet thereof faces the inside of the body of the container; and the one-way valve (2) is arranged in the body of the container, and can open and close the air outlet of the ventilation pipe (1). The ventilation device avoids the deformation or damage of the container caused by the fact it is easy to generate the difference between the air pressures inside and outside the container when bulk cargoes are transported with the container, thereby achieving the purpose of safely transporting and safely unloading bulk cargoes with the container.
