A filtering device for biopharmaceuticals

Abstract

The present invention discloses a filtering device for biopharmaceuticals, and relates to the field of biopharmaceutical filtering technology. The present invention includes a filter frame, a water inlet tray, and a plurality of membrane packages, wherein the water inlet tray and the membrane package can be stacked and pressed in the filter frame, and a water inlet cavity and a drainage cavity are provided inside the water inlet tray, and a water inlet pipe and a drainage pipe are provided outside the water inlet tray, wherein the water inlet pipe is connected to the water inlet cavity, and the drainage pipe is connected to the drainage cavity, and a deep filter element is fixedly installed inside the membrane package. By controlling the adjustment ring plate to slide downward, the adjustment ring plate squeezes the air ring, and the air pressure inside the air ring increases, and the air pressure is greater than the elastic force of the tension spring and the top spring, and the air pressure pushes the valve plate to block the drainage port, and drives the connecting ring to rise away from the second water guide hole below, and away from the one-way rubber valve sheet, at which time the membrane package and the membrane package above it do not participate in the filtration, and only the membrane package below participates in the filtration, and there is no need to disassemble the membrane package, which is convenient to use.
