[0033] see Figure 1-Figure 11 As shown, a magnetic stirrer with noise reduction function of the present invention includes a coupling assembly and a stirring shaft 1, wherein the coupling assembly includes a magnetic motor 2, an adjustment sleeve 3, a driving bolt 4 and a motor outer cover 5, which drives the One end face of the bolt 4 and the stirring shaft 1 are bolted and fixed; the side surface of the driving bolt 4 is connected with the adjusting sleeve 3 through a bearing; the magnetic motor 2 is bolted with the adjusting sleeve 3; the motor outer cover 5 is bolted and fixed to the magnetic motor 2 External, and both are sealed structures;

[0034] The adjusting sleeve 3 includes a mounting plate 301 and an adjusting plate 302, and one surface of the mounting plate 301 is welded with several spiral plates 303; one end surface of the spiral plate 303 extends above the adjusting plate 302, and the adjusting plate 302 and the spiral plate 303 are slidably matched. In orde...

Embodiment 2

[0040] It should be further explained that several damping rods 305 are installed between two adjacent spiral plates 303, and the opposite end surfaces of the damping rods 305 are bolted and fixed with the mounting plate 301 and the adjusting plate 302 respectively; the upper surface of the mounting plate 301 is welded with a fixing sleeve 3011 , a sliding sleeve 3022 is welded on the lower surface of the adjustment plate 302, and the fixed sleeve 3011 and the sliding sleeve 3022 are nested and slidably matched with each other;

[0041] In addition, the motor outer cover 5 includes a protective cover 501 and a heat dissipation pipe 502, wherein the protective cover 501 is a flexible pipe cover structure, and its opposite ends are bolted and fixed with the mounting plate 301 and the adjustment plate 302 respectively; the heat dissipation pipe 502 is a spiral hose structure, its opposite ends are respectively fixed and installed on the opposite ends of the protective cover 501, a...

Embodiment 3

[0043] In the present invention, the driving magnetic plate 201 and the driven magnetic plate 402 are both permanent magnet plates. During operation, the two magnetic plates are coupled between the sliding sleeve 3022 and the fixed sleeve 3011, and the two magnetic plates are under the mutual magnetic action. , the magnetic motor 2 drives the driving magnetic plate 201, and then the driven magnetic plate 402 drives the driving bolt 4 to rotate, and drives the stirring shaft 1 to rotate to stir the material;

[0044] Wherein, when the adjusting ring 304 is rotated, the screw structure between the remaining spiral plates 303 can be used to drive the adjusting plate 302 to slide, adjust the distance between the adjusting plate 302 and the mounting plate 301, and change the magnetic field intensity by changing the distance between the two magnetic plates. Then adjust the stirring speed;

[0045] In addition, in the present invention, the magnetic motor 2 is a BLB92-B brushless DC ...

Abstract

The invention discloses a magnetic stirrer with noise reduction function, which relates to the technical field of chemical product production and processing equipment. The invention includes a magnetic motor, an adjusting sleeve, a driving bolt and a stirring shaft. The stirring shaft is connected and fixed with the driving bolt bolt, and the driven magnetic plate of the driving bolt and the driving magnetic plate of the magnetic motor are coupled to each other. The invention improves the connection mode between the motor and the stirring shaft in the stirrer, changes the mechanical connection to the magnetic coupling connection, changes the copper rotor in the magnetic coupling to the permanent magnet rotor, and participates the magnetic field in the magnetic coupling relationship, so that the The working process of the agitator is more stable, avoiding vibration and fluctuation in the process of speed regulation, and effectively reducing noise; by setting the ball, it can provide support and lubrication when the driving bolt and the adjusting sleeve rotate, further shock absorption and noise reduction; Opening air vents on the surfaces of the sliding sleeve and the fixed sleeve can accelerate the air circulation and heat dissipation between the two magnetic plates, reduce the air vibration there, and effectively reduce noise.

Description

technical field [0001] The invention belongs to the technical field of chemical product production and processing equipment, in particular to a magnetic stirrer with a noise reduction function. Background technique [0002] In the production and processing process of some chemical products, it is usually necessary to stir the liquid phase materials evenly, so as to facilitate the full reaction in the reaction kettle, so as to add a stirrer structure for auxiliary work; the existing stirrer usually works through the mechanical connection of the motor. In actual work, mechanical vibration is often generated due to its internal working principle, resulting in a lot of noise; in work, these noises will not only affect the working environment and the physical and mental health of the staff, but also affect the materials inside the equipment. Resonance and other phenomena will occur, affecting the molecular structure and processing state of the material, and adversely affecting th...
