Problems solved by technology

Some reagents or reaction solvents must be in a closed environment while stirring, so it is impossible to use a mechanical stirrer with a stirring head and a stirrer integrated, and a magnetic stirrer with a separable two must be used
[0003] In the process of stirring reagents or reaction solvents, there are the following problems: the shape of the bottom of the container containing reagents or reaction solvents will often disturb the movement of the magnetic stirrer, and the friction and collision between the two will often cause the magnetic stirrer to move. Stopping or jumping will destroy the coupling between the magnetic stirrer and the moving magnetic field in the magnetic stirrer, thereby affecting the accuracy of the experiment; during the process of stirring reagents or reaction solvents, the traditional magnetic stirrer rod-shaped design will cause the bottom of the container containing the reagents or reaction solvents to wear Magnetic Stirrer Housing

Embodiment 1

[0037] Such as Figure 1-6 As shown, the anti-disturbance and wear-resistant magnetic stirrer of this embodiment includes a rotor body 1, a first ceramic shaft 2, a plastic bearing 3, a bearing protection shell 4, a flexible base 5, and a magnetic field reconstruction module 6; the rotor body 1 includes a plastic shell 1a, which is composed of two left-right symmetrical shells; a magnet 1b is arranged inside the plastic shell 1a, and the magnet 1b is in the shape of a strip, and a rotating shaft installation hole is opened in the center of the bottom of the plastic shell 1a. Vertically arranged, the upper end of the first ceramic shaft 2 is correspondingly inserted into the shaft installation hole and has an interference fit with the shaft installation hole; the plastic bearing 3 includes a coaxial inner ring body 3a and an outer ring body 3b, and the inner ring body 3a and the outer ring body A number of glass balls 3c are evenly distributed along the circumferential directio...

Embodiment 2

[0050] Such as Figure 7-8 As shown, the difference from Example 1 is that the magnet 1b is strip-shaped, the left and right ends of the plastic casing 1a of the rotor main body 1 are slidably connected with movable sleeves 16, and the front and rear sides of the plastic casing 1a of the rotor main body 1 are both A fixed rod 17 is fixed by a buckle, and the inward end of the fixed rod 17 is connected with the middle part of the plastic casing 1a of the rotor body 1, and the outward end of the fixed rod 17 is slidably connected with a movable sleeve 2 18, and the movable sleeve 18 is connected with the movable sleeve One 16 is vertical, and the left and right sides of movable sleeve 2 18 and movable sleeve 1 16 are arranged in sequence along the length direction to be provided with a number of inclined guide fins 19, and the guide fins 19 on the left and right sides of each movable sleeve are symmetrically arranged. The inclination angle between the guide fins 19 and the corre...

Embodiment 3

[0052] Such as Figure 9 As shown, the difference from Embodiment 1 is that: the bottom surface of the reinforcement support bar 5b and the center base 5a are located in the same plane, and several groups of circumferential reinforcement components radially distributed outwards are arranged on the flexible base 5, The circumferential reinforcement assembly includes several arc-shaped reinforcement connecting bars 13 arranged between any two circumferentially adjacent reinforcing support bars 5b, and the reinforcing connecting bars 13 are made of rubber or silica gel. Reinforcing the connecting strip 13 can further improve the grip stability of the flexible base 5 and prevent the flexible base 5 from shaking.

Abstract

The invention discloses an anti-disturbance wear-resistant magnetic stirrer and a use method thereof in the field of magnetic stirring. The magnetic stirrer comprises a rotor main body, a first ceramic rotating shaft, a plastic bearing, a bearing protection shell, a flexible base and a magnetic field reconstruction module. The use method comprises the following steps: preparing the rotor main body; preparing the flexible base, and mounting the bearing protection shell on the flexible base; ensuring that the magnetic stirrer is forwardly and horizontally placed at the bottom of a container containing a to-be-stirred solution; placing the magnetic field reconstruction module between the container containing the to-be-stirred solution and a working platform of the magnetic stirrer; and adjusting the magnetic stirrer to enable the rotor main body to rotate stably. The phenomenon that the rotor main body stops rotating or jumps can be effectively reduced or avoided, and meanwhile, the shell of the rotor main body is prevented from being abraded by the bottom shape of the container.

Description

technical field [0001] The invention belongs to the field of magnetic stirring, in particular to an anti-disturbance and wear-resistant magnetic stirring bar and a using method thereof. Background technique [0002] In the prior art, a magnetic stirrer is widely used in various magnetic stirrers as a stirring device directly in contact with reagents. The magnetic stirrer uses the coupling effect of the magnetic field to realize the rotation of the magnetic stirrer through the coupling of the magnetic stirrer and the moving magnetic field in the magnetic stirrer, so as to achieve the stirring effect on the reagent or the reaction solvent. Some reagents or reaction solvents must be in a closed environment while stirring, so a mechanical stirrer with a stirring head and a stirrer integrated cannot be used, and a magnetic stirrer with a separable two must be used. [0003] In the process of stirring reagents or reaction solvents, there are the following problems: the shape of t...
