TECHNICAL FIELD

[0001] The utility model relates to centrifugal device technical field, specifically point to a kind of chemical raw material centrifugal device. BACKGROUND

[0002] Chemical raw material centrifugal device used in laboratory is a kind of equipment using centrifugal force to separate, purify and other operations of chemical raw materials. It is mainly composed of motor, rotor, centrifugal tube and other components. Motor drives rotor to rotate at high speed, so that the chemical raw materials placed in the centrifugal tube on the rotor are subjected to centrifugal force. Different density or particle size components will settle or stratify at different speeds under centrifugal force, so as to realize separation.

[0003] In current laboratory operation, chemical raw material centrifuge plays a key role, but also has some drawbacks that cannot be ignored. During use, the running state of centrifuge is relatively closed, and it is difficult for the operator to intuitively observe the internal situation. Once leakage occurs, it is often difficult to detect in time, which not only may pollute the experimental environment, but also will interfere with the accuracy of experimental results. In addition, after centrifugation, the centrifuge will not stop running instantly due to inertia and mechanical principle. At this time, if the operator lacks standard operation consciousness, and rashly reaches out to take the sample, it is easy to cause serious safety accidents and cause irreparable harm to oneself, which lays a huge hidden danger for experimental safety.
