Description
Technical Field
[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge with a shock-absorbing structure. Background Art
[0002] A centrifuge is a mechanical device that uses centrifugal force to separate liquids from solid particles or the components of a liquid-liquid mixture. It is widely used in biology, medicine, agriculture, chemical industry, petroleum and other fields. The main functions of a centrifuge include separating solid particles from liquid in a suspension, separating two immiscible liquids of different densities in an emulsion, and removing liquid from wet solids. In addition, some special types of centrifuges, such as ultra-speed tubular separators, can also separate gas mixtures of different densities.
[0003] Centrifuges in the prior art usually use the high rotation of the motor to drive the centrifugal disk to rotate at high speed to generate centrifugal force. However, the high-speed rotation of the motor is prone to vibration, so shock absorbers are generally installed for vibration reduction. However, the existing shock absorbers are all fixed on the box and their positions cannot be adjusted. In actual work, centrifugal components of different types and different speeds may also have different sizes, requiring different shock absorbers to match them. The shock absorbers are inconvenient to adjust and are not conducive to adapting to different centrifugal components. For this reason, we propose a centrifuge with a shock-absorbing structure.
