Storage device

The utility model relates to the technical field of gluconic acid-delta-lactone production, and discloses a storage device which comprises a shell, a storage cavity is formed in one side of the interior of the shell, a piston groove is formed in the other side of the interior of the shell, an electric-hydraulic push rod is fixedly connected to the upper surface of the shell through bolts, and the telescopic end of the electric-hydraulic push rod penetrates through the inner wall of the top end of the piston groove and is fixedly connected with the middle of the upper surface of a piston. An electric-hydraulic push rod is controlled to work, a piston can be pulled to move upwards in a piston groove, a gluconic acid solution at the bottom end in a storage cavity can be pumped into the piston groove through a liquid pumping pipe, an adjusting plate can further drive a spraying pipe on the outer side of a rotating pipe to rotate, and therefore the gluconic acid solution in the storage cavity is evenly stirred; th
