DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-3 A telescopic frame-type stirring device includes a lifting assembly, a stirring shaft 1, and a telescopic frame assembly. The lifting assembly is connected to the upper end of the outer wall of a tank body 2, and the telescopic frame assembly is disposed within the tank body 2. The upper end of the stirring shaft 1 is connected to the lifting assembly, while the lower end extends into the interior of the tank body 2 and is connected to the telescopic frame assembly. A mechanical seal 17 is provided at the point where the stirring shaft 1 and the tank body 2 intersect. The lifting assembly drives the stirring shaft 1 up and down, thereby adjusting the outer diameter of the telescopic frame assembly.

[0025] Specifically, the lifting assembly includes a fixed base 10, the upper end of which is connected to four guide shafts 11. Each guide shaft 11 is connected to a sliding sleeve 12. A fixed plate 13 is connected between the four sliding sleeves 12. The fixed plate 13 is connected to a stirring motor 14, and the output end of the stirring motor 14 is connected to the upper end of the stirring shaft 1. The upper ends of the four guide shafts 11 are connected to a top plate 15, which is connected to a screw elevator 16. The output end of the screw elevator 16 passes through the top plate 15 and connects to the fixed plate 13. The output end of the screw elevator 16 is connected to the fixed plate 13 via a connecting bracket 19.

[0026] Specifically, the output end of the screw elevator 16 is extended and retracted to drive the fixed plate 13 to move up and down, thereby enabling the stirring shaft 1 to move up and down to open and close the telescopic frame.

[0027] Specifically, the telescopic frame assembly includes a first rotating base 3, a second rotating base 4, two first connecting rods 5, two second connecting rods 6 and two frame-type paddles 7; the first rotating base 3 is rotatably connected to the upper ends of the two first connecting rods 5, and the lower ends of the two first connecting rods 5 are rotatably connected to the lower ends of the two frame-type paddles 7; the second rotating base 4 is rotatably connected to the lower ends of the two second connecting rods 6; a slide groove 8 is provided on the two frame-type paddles 7, and the upper ends of the two second connecting rods 6 are each connected to a slider 9, and each is slidably connected in the slide groove 8 of the corresponding frame-type paddle 7; the intersection of the two first connecting rods 5 and the two second connecting rods 6 is rotatably connected via a rotating shaft 20. The first rotating base 3 is connected to the lower end of the stirring shaft 1. The inner bottom surface of the tank body 2 is connected to the bottom bracket 18, and the second rotating base 4 is connected to the bottom bracket 18.

[0028] Specifically, when the stirring shaft 1 moves downward, it pushes the first rotating base 3 to move downward. The downward movement of the first rotating base 3 pushes the two frame-type paddles 7 to open through the two first connecting rods 5 and the two second connecting rods 6.

[0029] This equipment adjusts the outer diameter of the telescopic frame assembly according to different materials and different process requirements, expands or contracts the outer contour size of the frame agitator, and adjusts the stirring speed to achieve the best flow characteristics and mixing effect of the stirred materials.

[0030] For materials requiring low-speed mixing, the operator lowers the agitator shaft 1, expanding the outer dimensions of the frame agitator. For materials requiring high-speed mixing, the operator raises the agitator shaft 1, shrinking the outer dimensions of the frame agitator. By adjusting the speed of the variable-frequency stirring motor 14 and the outer diameter of the frame agitator, this device can create countless different combinations to meet the mixing needs of materials with different characteristics.

[0031] This retractable frame-type stirring device features adjustable frame agitator dimensions and is equipped with a variable-frequency motor to accommodate reactions and mixing of materials with varying viscosities. During stirring, the stirring speed and outer diameter of the frame can be adjusted based on viscosity changes to ensure optimal mixing. This also effectively prevents motor overheating and overload, ensuring safe operation of the equipment. Suitable for laboratory use, it improves production efficiency, reduces equipment procurement costs, and enables multiple uses for a single tank. The device is equipped with a dedicated mechanical seal, allowing operators to operate under pressure, ensuring stable tank pressure and improving production efficiency. The frame-type stirring device's speed and dimensions can also be adjusted based on the specific material volume to meet production needs.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
