[0003] In the prior art, calcium oxide powder is stored in a storage bin for too long, and is easily found to be bonded after absorbing moisture. In the process of feeding, it is easy for the calcium oxide powder to form arches and bridges. Once arches and bridges occur, blockages will occur and affect feeding. In addition, calcium oxide powder will form block calcium oxide after absorbing moisture and bonding. Block calcium oxide affects the discharge and is not conducive to stirring pulp in the subsequent process. Therefore, a storage tank bin for calcium oxide production is proposed.
