Swing-bucket-rotor for centrifugal machine

Abstract

The invention discloses a swing-bucket-rotor for a centrifugal machine. The swing-bucket-rotor comprises a swing-bucket-rotor body and a hanging basket installed on the swing-bucket-rotor body; the swing-bucket-rotor body is of a hollow annular structure, and a hollow connecting ring is arranged in an inner cavity of the swing-bucket-rotor body; an annular groove is formed in the hollow connecting ring, and the section of the annular groove is in an inclined U shape; a plurality of rectangular grooves are formed in the hollow connecting ring in the radial direction of the hollow connecting ring, the rectangular grooves are annularly arranged, the rectangular grooves communicate with the annular groove, and the rectangular grooves communicate with the inner cavity of the swing-bucket-rotor body; and cone-frustum-shaped protruding parts matched with the annular groove are arranged on the two sides of the opening end of the hanging basket, and the cone-frustum-shaped protruding parts on the two sides of the hanging basket are clamped in the annular groove and located at the bottom of the annular groove. During high-speed centrifugation, the hanging basket is automatically stored in the swing-bucket-rotor body, an approximately complete cake-shaped rotating body is synthesized, the wind resistance is small, the size is smaller than that of a conventional swing-bucket-rotor with the same centrifugal capacity, the wind resistance is greatly reduced, the working energy consumption of the centrifugal machine is reduced, and high-speed operation can be achieved.

Description

technical field [0001] The invention relates to the technical field of laboratory centrifuge devices, in particular to a swing-out rotor for a centrifuge. Background technique [0002] The centrifuge is provided with a rotor and a drive member for rotationally driving the rotor in a centrifuge chamber. The drive member rotates the rotor in the centrifuge chamber to exert centrifugal force, thereby centrifuging the sample in the sample container. The rotors used in centrifuges can be roughly divided into angle rotors and swing-flat rotors. In the case of an angle rotor, a number of sample containers filled with samples are accommodated in a storage hole, the storage hole is formed at a certain angle with respect to the drive shaft, and regardless of the magnitude of the centrifugal force, the storage hole and the drive shaft The relative angle of is always fixed. In addition, there are many cases where a rotor cover is installed in the opening on the upper part of the roto...
