System and method for batch preparation of high-temperature superconducting bulks

Abstract

The invention provides a system and method for the batch preparation of high-temperature superconducting bulks. The system comprises a printing output assembly and a 3D printing slurry preparation assembly. In the 3D printing slurry preparation assembly, a powder feeding mechanism and a reagent feeding mechanism are respectively used for feeding a powdery raw material and a liquid reagent into a stirring cavity of a slurry stirring and mixing mechanism; the slurry stirring and mixing mechanism is used for stirring and mixing the fed powdery raw materials and the liquid reagent, and after 3D printing slurry is obtained, the 3D printing slurry is conveyed to a printing output mechanism in the printing output assembly through a spiral conveying mechanism; the printing output mechanism printsand forms the received 3D printing slurry on a printing platform through a printing nozzle, in the printing process, the printing output mechanism is driven by a moving mechanism to move in the X direction and the Y direction, and the printing platform is driven by a lifting mechanism to move in the Z direction. The invention provides an efficient preparation system and method based on a 3D printing technology. The full-automatic batch preparation of yttrium-barium-copper-oxygen high-temperature superconductors can be achieved.
