[0004] The present utility model is to solve the technical problem of providing a sterilization filtration device that can accelerate the filtration speed.

[0005] To solve the above technical problems, the technical solution of the sterilization filtration device of the present utility model is as follows:

[0006] The filter seat is connected with filter paper inside; an outer threaded connection sleeve and an inner connection sleeve coaxial with the outer threaded connection sleeve are connected below the filter seat; an air extraction channel is opened on the filter seat; the air outlet of the air extraction channel is located on the side surface of the filter seat, and a connector is connected to the air outlet of the filter seat; the air inlet of the air extraction channel is located on the bottom surface of the inner connection sleeve; a container is threadedly connected to the outer threaded connection sleeve; a sleeve is detachably connected to the top of the filter seat; a suction pipe is sleeved on the connector; and a suction cylinder is connected to the outer end of the suction pipe.

[0007] An upper cover is placed above the sleeve.

[0008] The filter seat and the sleeve are flange-connected.

[0009] A threaded connector is connected to the outer end of the suction pipe; and the threaded connector is threadedly connected with the suction cylinder.

[0010] The threaded connector is connected with connecting columns on both sides, the connecting columns are threadedly connected with locking bolts, the air extraction cylinder is provided with plug-in grooves corresponding to the locking bolts, and the bottom ends of the locking bolts are inserted into the plug-in grooves through the connecting columns.

[0011] The sterilization and filtration device can achieve the following technical effects: serum to be sterilized and filtered is poured into the sleeve above the filter seat, and then the serum is filtered through filter paper to remove viruses and bacteria, and during the filtration, the air in the container is extracted by the air extraction cylinder to form negative pressure in the container, thereby accelerating the filtration of the serum; and the air inlet of the air extraction channel is located on the bottom surface of the inner sleeve, so that the serum is not easy to drop into the air inlet of the air extraction channel after being filtered by the filter paper, and the serum can be collected in the container.
