The invention relates to the technical field of
zinc oxide transportation, and discloses a damp-proof device for
zinc oxide transportation and distribution. The device comprises a storage box, the front surface of the storage box is fixedly connected with a fixed cylinder, a
piston A is sleeved with the inner wall of the fixed cylinder, and the inner wall of the top surface of the fixed cylinder is fixedly connected with a material injection cylinder with a hole in the front surface. By arranging the material injection cylinder, and by means of the water
absorption capacity of a hydrophilic material, air is automatically injected into an
air cushion when
moisture exists in the environment, the gap at the joint between a box cover and the storage box is sealed, and therefore the situation that
moisture permeates in through the gap between the box cover and the storage box, and consequently
zinc oxide is affected with damp is avoided; compared with an existing sealing mechanism, the damp-proof device is automatically triggered according to the environment
humidity, and has the advantages that no operation steps are added for sealing the storage box through the box cover, and the service life is not shortened due to continuous unfolding; and in addition,
moisture in the environment is used for driving, energy sources such as
electricity are not needed, and the advantages of
energy conservation and
environmental protection are achieved.
