Description

Technical Field

[0001] The invention relates to the technical field of flat ceramic membrane components, in particular to a flat ceramic membrane overlap component. Background Art

[0002] Ceramic membrane is a type of inorganic membrane and belongs to the solid membrane material in membrane separation technology. It is mainly supported by inorganic ceramic materials such as aluminum oxide, zirconium oxide, titanium oxide and silicon oxide of different specifications, and is made by surface coating and high-temperature firing. Ceramic membranes are resistant to acids and alkalis, high temperatures and chemically stable in extreme environments. The pore size of commercialized ceramic membranes is small, so they can successfully achieve molecular-level filtration. Therefore, they are mainly used for filtering and separating liquid and gaseous mixtures. They can replace traditional separation technologies such as centrifugation, evaporation, distillation and filtration to achieve the goal of improving product quality and reducing production costs. They have broad application prospects in harsh environments such as the petroleum and chemical industries.

[0003] However, there are still some problems to be solved in the assembly process of the flat ceramic membrane overlap assembly currently used with the flat ceramic membrane. First, the installation method of the flat ceramic membrane and the overlap assembly is usually that the flat ceramic membrane is installed inside the slot structure of the overlap assembly mainboard, but the flat ceramic membrane itself has the characteristics of high brittleness and low elasticity of inorganic materials. If the mainboard slot and the flat ceramic membrane are fixedly installed by a snap-on method, the friction and extrusion force on the surface of the flat ceramic membrane during the installation process may cause cracks in the flat ceramic membrane and produce defective products. Therefore, a movable sleeve method is usually adopted for fixed installation. In this way, the friction and extrusion force on the surface of the flat ceramic membrane during the installation process will be much smaller, but there may be a gap in the connection between the flat ceramic membrane and the overlap assembly mainboard, and the tightness of the connection structure of the assembled flat ceramic membrane assembly itself may not meet the standard. Second, the connection structure of the existing two sets of identical overlap assemblies is usually an external structure. Although the fixed connection between the two can be achieved, the protrusion of the external structure will cause some trouble to the subsequent assembly of the overall equipment.
