Description

Technical Field

[0001] This utility model relates to the technical field of surface treatment, and in particular to a magnetic stirring device. Background Technology

[0002] Currently, among the surface treatment equipment on the market, liquids need to be stirred to maintain uniformity. In these stirring structures, motors installed outside the tank are inserted into the tank via shafts to stir the liquid. This can easily lead to leakage or contamination of the liquid inside the tank. Moreover, replacing and maintaining the motor after it is damaged is inconvenient, as it requires disassembling the entire structure. Utility Model Content

[0003] One objective of this invention is to provide a magnetic stirring device that controls the rotation of the stirring shaft with magnetic force, eliminating the need to disassemble the entire machine when maintaining the motor, thereby reducing maintenance time and minimizing liquid leakage and contamination.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A magnetic stirring device includes a stirring tank, a mounting shaft, a driving orthogonal magnetic wheel, a driven orthogonal magnetic wheel, and a stirring shaft. The mounting shaft is horizontally mounted at the lower end of the stirring tank. The driving orthogonal magnetic wheel is mounted at one end of the mounting shaft. A tank bottom plate is fixed in the middle of the stirring tank, and a fixed seat is mounted in the middle of the tank bottom plate. The stirring shaft rotates on the fixed seat. The driven orthogonal magnetic wheel is mounted at one end of the stirring shaft and is located inside the fixed seat. The driving orthogonal magnetic wheel and the driven orthogonal magnetic wheel are magnetically connected. A stirring blade is mounted at the other end of the stirring shaft.

[0006] As a preferred technical solution, a bearing mounting seat is installed on the fixed seat, and the stirring shaft passes through the middle of the bearing mounting seat.

[0007] As a preferred technical solution, the stirring blades and the stirring shaft are fastened together by screws.

[0008] As a preferred technical solution, a stirring motor is installed on the stirring tank, and the stirring motor drives the rotation of the mounting shaft.

[0009] As a preferred technical solution, the stirring motor is located on the outside of the stirring tank, and the end of the mounting shaft away from the active orthogonal magnetic wheel passes through the side wall of the stirring tank and is keyed to the drive end of the stirring motor.

[0010] The beneficial effects of this utility model are as follows: It provides a magnetic stirring device, which uses orthogonal magnetic wheels for magnetic control. Compared with directly connecting the motor to the stirring shaft, it ensures the integrity of the stirring tank, reduces leakage and contamination of the liquid in the tank, and makes it easier to replace the motor while maintaining the integrity of the internal structure.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown in this embodiment, a magnetic stirring device includes a stirring tank 1, a mounting shaft 2, an active orthogonal magnetic wheel 3, a driven orthogonal magnetic wheel 4, and a stirring shaft 5. The mounting shaft 2 is horizontally mounted at the lower end of the stirring tank 1. The active orthogonal magnetic wheel 3 is mounted at one end of the mounting shaft 2. A tank bottom plate 6 is fixed in the middle of the stirring tank 1, and a fixed seat 7 is mounted in the middle of the tank bottom plate 6. The stirring shaft 5 rotates on the fixed seat 7. The driven orthogonal magnetic wheel 4 is mounted at one end of the stirring shaft 5 and is located inside the fixed seat 7. The active orthogonal magnetic wheel 3 and the driven orthogonal magnetic wheel 4 are magnetically connected. A stirring blade 8 is mounted at the other end of the stirring shaft 5.

[0017] When the mounting shaft 2 rotates, it causes the active orthogonal magnetic wheel 3 to rotate. Through magnetic control, the driven orthogonal magnetic wheel 4 drives the stirring shaft 5 to rotate. Specifically, the relative positions of the magnetic poles change, adjacent opposite magnetic poles generate attraction, and like magnetic poles generate repulsion, which together drive the rotation of the stirring shaft 5, causing the stirring blades 8 to rotate. The stirring blades 8 can then stir the liquid in the stirring tank 1. With the bottom plate 6 closed, the liquid in the stirring tank 1 will not leak or become contaminated.

[0018] A bearing mounting seat 9 is installed on the fixed seat 7. The stirring shaft 5 passes through the middle of the bearing mounting seat 9. Under the action of the bearing mounting seat 9, the rotation of the stirring shaft 5 remains stable, and the liquid in the stirring tank 1 will not seep into the fixed seat 7.

[0019] The mixing blades 8 and the mixing shaft 5 are fastened together by screws. The screw fastening method is simple and convenient, and the installation is relatively stable.

[0020] A stirring motor 10 is installed on the stirring tank 1. The stirring motor 10 drives the rotation of the mounting shaft 2. The stirring motor 10 is located on the outside of the stirring tank 1. The end of the mounting shaft 2 away from the active orthogonal magnetic wheel 3 passes through the side wall of the stirring tank 1 and is keyed to the drive end of the stirring motor 10. The stirring motor 10 provides power to make the mounting shaft 2 rotate, thereby controlling the rotation of the active orthogonal magnetic wheel 3. When the stirring motor 10 is damaged, it can be directly disassembled from the outside of the stirring tank 1 without affecting any internal structure of the stirring tank 1.

[0021] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
