Description
Technical Field

Background
The flat ceramic membrane is prepared by taking inorganic ceramic materials such as alumina and the like as raw materials, adopting extrusion molding, and then coating, drying and sintering. The flat ceramic membrane has the advantages of high strength, long service life, high filtering precision, high temperature resistance, organic solvent resistance, acid and alkali corrosion resistance and the like, is a core component of a Membrane Bioreactor (MBR) and a drinking water purifier, and is widely applied to drinking water purification, beverage concentration and industrial and domestic sewage treatment.
The hollow flat ceramic membrane mainly realizes the filtration and separation of pollutants in sewage in a mode of applying external pressure to generate transmembrane pressure difference. When the sewage filtering and purifying device is used, the two ends of the ceramic membrane are respectively sealed by the sealing plug and the water collecting plug, negative pressure suction is carried out at one end of the water collecting plug, sewage flows through micropores of a membrane layer on the surface of the ceramic membrane under the action of the negative pressure suction, particulate matters and bacterial microorganisms are intercepted on one side of the outer surface of the membrane layer, purified water enters the bundling pore canal inside the ceramic membrane through the micropores, and the purified water in the bundling pore canal is discharged through the water collecting pipe after the water collecting plug is converged, so that the sewage filtering and purifying device is realized. In recent years, the ultra-clean water all-ceramic membrane has higher strength, better corrosion resistance, longer service life, greener and safer application, the sealing element and the binder of the all-ceramic membrane are both inorganic ceramic materials, and the inorganic binder can obtain the required bonding strength and filtering precision after being dried or sintered at high temperature. At present, most sealing elements matched with a flat ceramic membrane are designed into a flat wedge-shaped structure, and the thickness of a membrane filter element comprising the ceramic membrane and the sealing element can be effectively reduced by the structure, but in the actual production process, the structure has a plurality of defects: firstly, in order to reduce the thickness of the membrane filter element as much as possible, the outer wall of the sealing element is usually thin, has low strength and is easy to generate distortion deformation, assembly errors are large, and the sealing element is easy to damage in the packaging and using processes; secondly, the greatest problem of the existing all-ceramic filter element is that: the sealing element and the ceramic membrane are horizontally placed, dried and sintered after being assembled, glued and sealed, the sealing elements at the two ends warp and are not in the same horizontal plane with the ceramic membrane, so that the product is deformed, the assembly is difficult, and the sealing effect and the filtering performance of the whole filtering element are affected. In addition, stress concentration exists in the element after buckling deformation, and the element is easily damaged in the long-time filter pressing and back flushing processes, so that the filter element cannot be used. The reason for the buckling deformation of the sealing element is that the wedge-shaped water collecting plug is unreasonable in structural design and poor in stability; on the other hand, the design of the positioning groove inside the water collecting plug is unreasonable, the depth of the positioning groove is insufficient, the membrane inserted into the positioning groove cannot be kept stable, and the assembled element can be shifted by slight external force, so that the integral quality of the assembled element is affected.
