Description

Technical Field

[0001] The utility model belongs to the field of filters, in particular to a ceramic membrane filter. Background Art

[0002] Ceramic filter membranes are usually used for fluid filtration and material separation. These membranes are made of porous ceramic materials and are semi-permeable membranes with separation functions. They are resistant to high temperatures, acids, alkalis, and organic solvents, and have the characteristics of narrow pore size distribution, high separation efficiency and separation precision.

[0003] The ceramic membrane filter is a ceramic membrane placed inside a containing tube, and the containing tube and the outer tube are connected by flanges and bolts. However, on the one hand, since the flange interface is a purely rigid connection, it is easy to cause water leakage; on the other hand, if the bolts are loose, it is also easy to cause water leakage.
