Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to an installation structure of a centrifuge driving component. Background Art

[0002] The motor of an existing centrifuge is often installed from bottom to top, and the motor is suspended above a support plate. Because the centrifuge needs to be accelerated and the heat generated during the friction between the centrifugal rotor and the air causes material failure, a vacuum system and a refrigeration system are often arranged in the support plate. Therefore, since the space in the support plate is very compact, if the drive component is installed from bottom to top, it is not convenient for subsequent disassembly and maintenance of the motor.

[0003] The utility model with publication number CN209049042U discloses a vacuum freeze-drying centrifugal concentrator, including a chassis, a touch screen installed on the chassis, a PLC control system, a centrifugal chamber, a centrifugal rotor, a first rotating shaft, a first magnet seat, a plurality of first magnets, a second magnet seat, a plurality of second magnets, a second rotating shaft, a variable frequency motor, a cold trap and a compressor installed in the chassis. However, when the variable frequency motor needs to be replaced, the variable frequency motor is not easy to disassemble and maintain because the centrifugal chamber and the components arranged in the centrifugal chamber are arranged above the motor, and the cold trap and the compressor are arranged below.

[0014] Optionally, a shock-absorbing sleeve is provided on the outer sleeve of the transmission cylinder, and the shock-absorbing sleeve is located between the transmission cylinder and the support seat, thereby reducing the vibration amplitude of the driving member during operation and stabilizing the entire centrifuge body.
