Swivel head cover of electric centrifuge

Abstract

The invention provides a swivel head cover of an electric centrifuge. According to the electric centrifuge frequently used in the laboratory presently, the swivel head cover flies out if the swivel head cover is not screwed tight, and accidents can be caused. The swivel head and the swivel head cover of the existing electric centrifuge are generally connected through threads and have the defect of being poor in sealing effect. The swivel head cover of the electric centrifuge comprises a swivel head cover body (1) connected with a swivel head cover flange (2), the swivel head cover flange is matched with a swivel head flange, and an annular protrusion (4) is arranged on the swivel head cover flange, located on the attachment surface of the swivel head cover flange and the swivel head flange and matched with an annular groove (5) arranged on the swivel head flange. The swivel head cover is applied to ancillary facilities of the electric centrifuge.

Description

technical field [0001] The invention relates to a chemical experiment apparatus, in particular to a rotor cover of an electric centrifuge for a laboratory. Background technique [0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. The centrifuge is mainly used to separate the solid particles in the suspension from the liquid; or to separate two different densities and immiscible liquids in the emulsion (such as separating cream from milk); it can also be used to remove Liquid in wet solids, such as drying wet clothes with a washing machine; special ultra-speed tube separators can also separate gas mixtures of different densities; using the characteristics of different sedimentation velocities of solid particles of different densities or particle sizes in liquids, some sedimentation Centrifuges can also classify solid particles by density or size. Centrifuges are widely used...

AI Technical Summary

Problems solved by technology

[0003] At present, electric centrifuges are commonly used in laboratories. Electric centrifuges rotate quickly. If you do not pay attention during use, there will be great safety hazards, especially if the rotor cover of the electric centrifuge is not tightened. The cover will fly out, causing an accident

The rotor and the rotor cover of the existing electric centrifuge are generally connected by threads. If the threads are not tightly matched during the tightening process or the threads are worn and the speed is too high, accidents will easily occur.

And the threaded connection has the defect that the sealing effect is not good, and a separate gasket needs to be added. However, some highly corrosive solutions are often used in chemical experiments, which may easily cause corrosion of the gasket and cause solvent leakage.
