Description

technical field [0001] The invention relates to the field of magnetic mixers, in particular to a combinable annular three-dimensional magnetic stirrer. Background technique [0002] The magnetic stirrer is a basic equipment widely used in chemistry, biology and other laboratories. It mainly generates a rotating magnetic field through the magnetic stirrer to drive the magnetons in the solution to rotate at high speed, and to drive the solution to rotate together, so as to achieve the purpose of stirring the solution. . Existing magnetic stirrers can be divided into two types: mechanical stirrers and electromagnetic stirrers. The mechanical type stirrer drives the permanent magnet to rotate through the electric motor to generate a rotating magnetic field; the electromagnetic type stirrer generates a quasi-rotating magnetic field by passing a sequential current into the solenoid coil inside the stirrer. Compared with the mechanical stirrer, the electromagnetic stirrer does no...

AI Technical Summary

Problems solved by technology

In this structure, the strength of the magnetic field in the space where the stirrer is located is limited, and the energy of the electromagnetic field cannot be fully utilized.

Since the current magnetic stirrers are all flat design, the stirrer also needs to provide a platform for placing the container, so it needs to occupy a considerable space, and it is not convenient to move
