[0002] In order to solve the defect that the traditional dead-end filtration method will cause the rapid accumulation of filter cake layer and gel layer, resulting in a decrease in filtration efficiency, more and more production processes adopt tangential flow filtration. Compared with the traditional dead-end filtration, the tangential flow filtration can form shear on the surface of the membrane during the filtration process, which plays a flushing role and effectively alleviates the accumulation of large particles and molecules on the membrane, reduces the generation of filter cake layer and gel layer, and ensures a stable flow rate. Therefore, it has a higher and more stable flow rate and high production efficiency. Several membranes are stacked layer by layer through dispensing equipment to form a membrane package. The existing dispensing equipment is generally only suitable for use with dispensing pads and cannot be used in automated assembly line production. The production efficiency is relatively low, and the existing dispensing equipment is prone to dripping glue onto the dispensing pad after the dispensing work is completed, which is difficult to clean.
