[0002] Separation and purification membrane package technology is a purification technology based on the principle of membrane separation, which is widely used in many industries, such as water treatment, biotechnology, food industry, electronics industry, drug production, etc. This technology uses artificial materials (membrane materials) to effectively separate different media to achieve purification purposes.
[0003] Tangential flow membrane package clamps, such as those in authorization announcements CN216691641U and CN219922601U, mainly consist of a clamping plate (pressure plate) and a connecting rod to form a space for clamping the membrane package, and a hydraulic cylinder provides clamping power to achieve clamping of the membrane package. At present, there are many brands of membrane packages on the market, especially different membrane package connection holes have different shapes such as circular holes and U-shaped holes, which make it impossible to connect and use them in combination with the same tangential flow membrane package clamp, affecting the universality of the tangential flow membrane package clamp.
