[0002] Solid fuel cell ceramic ion membrane is one of its core components, usually made of zirconium oxide or other oxide materials, mainly for ion conduction. The performance and life of these ceramic membranes are closely related to their purity, microstructure and membrane surface quality, therefore, in the production process, removing impurities and maintaining high purity of the membrane are key steps.

[0003] The existing ion membrane production solution impurity removal device can remove the fine particle impurities in the solution by using a membrane filter with a specific pore size to filter out the fine particles, suspended solids and macromolecular organic matter in the solution. However, in actual use, after the membrane filter is used for a long time to remove impurities from the solution, a large amount of impurities is attached to the surface of the ultrafiltration membrane, and the ultrafiltration membrane itself needs to be cleaned regularly by opening the membrane filter. However, the ultrafiltration membrane is usually fragile, and excessive bending or impact may cause the membrane to break or its performance to decrease, resulting in a large amount of time spent on disassembling and assembling the membrane filter, which is inconvenient to use.

[0004] Therefore, we propose a solid fuel cell ceramic ion membrane production solution impurity removal device to solve the above problems. UTILITY MODEL CONTENTS
