Embodiment Construction

[0015] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.

[0016] As shown in the figure, an electromagnetic stirring device, the device body 1 is a cuboid, the side wall is provided with a shielding layer, the device body 1 is provided with a cuboid stirring chamber 4 with an opening on the top, a sealing cover 5 is provided at the opening, and the middle part of the sealing cover 5 is directed to the stirring chamber. The chamber 4 protrudes and fits with the inner wall of the stirring chamber 4, a back-shaped chamber 11 is formed between the chamber wall of the stirring chamber 4 and the side wall of the device body 1, and the electromagnet 2 is sleeved on the wall of the stirring chamber 4. Outside, and in the back-shaped cavity 11, the electromagnet 2 is rectangular, and is composed of a rectangular iron core 21 and a coil 24. The rectangular iron core 21 is formed by stacking a plurality of ba...

Abstract

An electromagnetic stirring device comprises a rectangular body, a stirring cavity is arranged in the rectangular body, a rectangular-ambulatory-plane cavity is arranged between the stirring cavity and the rectangular body, electromagnet is arranged in the rectangular-ambulatory-plane cavity and around the stirring cavity, four corners in the inner side of the iron corn of the electromagnet are both provided with a wire duct, two neighbored wire ducts form a winding plate for winding the coils, the coil can be divided into two coil groups, each coil group comprises two coils with the same winding direction, wherein the two coils are connected and arranged on two opposite winding plates; and the rectangular body delivers alternating current in regular change to the coils through a controller, so that the electromagnet can form a rotary uniform strong magnetic field in the stirring cavity. The device generates a rotary uniform strong magnetic field with orderly changed directions in the stirring cavity through optimizing the iron core structure and introducing current in regular change to the coils to drive a plurality of permanent magnetic stirrers to rotate so as to achieve the goal of stirring multiple samples at the same time.

Description

technical field [0001] The invention relates to an electromagnetic stirring device, in particular to a device capable of simultaneously performing electromagnetic stirring on a plurality of samples. Background technique [0002] Magnetic stirring is a technology that drives the rotation of a permanent magnetic stirrer by changing the direction of the magnetic field to stir the test material. The magnetic stirring device can stir the test materials under airtight conditions, which has great advantages in the tests of preventing volatilization and aseptic stirring. However, the traditional magnetic stirring device drives the permanent magnet to rotate through a DC motor to form a rotating magnetic field with a certain point as the center, thereby driving the permanent magnetic stirrer at the center to rotate with the magnetic field. Therefore, a magnetic stirring device often can only drive a single permanent magnetic stirring bar to process a single sample, which affects the...
