Technical Field

[0001] The invention relates to the technical field of serum filtration, in particular to a three-stage high-throughput sterilizing filtration and purification device for animal serum. Background Art

[0002] Serum is a very complex mixture formed by removing fibrin from plasma. Serum contains various plasma proteins, polypeptides, fats, carbohydrates, growth factors, hormones, inorganic substances, etc. These substances are a means to achieve physiological balance by promoting cell growth or inhibiting growth activity.

[0003] In the prior art, a Chinese patent with publication number "CN214389110U" discloses a multi-stage filtering device for bovine serum. By arranging a multi-layer filter screen with successively decreasing mesh apertures in the filter cartridge, the bovine serum can be filtered step by step, and the retained particles can be transferred step by step, effectively reducing the probability of filter screen clogging; the filter cartridge is set to a reversible structure, and under the action of a flushing pipe, the filter screen can be reversely flushed, and waste residue can be discharged from the residue discharge port, which greatly facilitates the cleaning operation of the filter screen; at the same time, a sealing plate is used to switch the blocking state of the residue discharge port, which can meet the needs of filtering and flushing at the same time, has strong flexibility and is easy to use, and solves the problem that the existing serum is easy to clog the filter screen when filtering.
