Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-fine powder processing and stirring devices, and particularly relates to a convenient high-speed stirring device for laboratory ultra-fine powder modification and mixing. Background Art

[0002] As a commonly used processing device for surface modification of ultra-fine powders, a high-speed mixer has many advantages and is commonly used in powder production factories and some powder modification laboratories. A high-speed mixer usually consists of a main mixing pot, a sealing cover, a stirring impeller, a driving motor, a machine base, etc. The specific process of surface modification of ultra-fine powders by a high-speed mixer is as follows: The powders to be modified and surface modifiers are placed together in the mixing pot. After covering the sealing cover, the high-speed mixer is started, and the stirring impeller rotates at a high speed. Under the action of the impeller, the materials collide and rub against each other, causing the material temperature to rise. The powders and surface modifiers are quickly cross-mixed, promoting the dispersion and contact of the powders and surface modifiers, thereby realizing the coating of the modifiers on the powders. However, it is not easy to pour the mixing pot after the modification is completed by a general high-speed mixer, which brings great inconvenience to the collection of powders and the cleaning of the mixing pot.

Specific Embodiments

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] Refer to Figure 1, A convenient high-speed stirring device for modifying and mixing ultra-fine powders in a laboratory, including two support frames 1 arranged in parallel with each other. The lower parts of the two support frames 1 are fixedly connected by a connecting cross bar 2. A mounting seat 3 is rotatably connected between the tops of the two support frames 1. The mounting seat 3 includes a bottom plate and side plates fixedly connected to both sides of the top end of the bottom plate. A mixing pot is fixedly connected between the two side plates. A stirring shaft is arranged inside the mixing pot, and a stirring impeller 8 is installed on the stirring shaft. The bottom end of the stirring shaft sequentially passes through the bottom wall of the mixing pot and the bottom plate and is fixedly connected to the output shaft of a driving motor 9. The driving motor 9 is fixedly installed at the bottom end of the bottom plate. The top ends of the two side plates on the side away from each other are respectively fixedly connected with a rotating shaft, and the two rotating shafts are respectively rotatably installed in the bearing seats 7 at the tops of the two support frames 1 through bearings.

[0017] In this embodiment, the connection between the mixing pot and the two side plates can adopt a direct welding connection method or a bolt connection method.

[0018] In this embodiment, the mixing pot includes a mixing pot body 4 and a sealing cover 5. The mixing pot body 4 is fixedly installed between the two side plates. The stirring impeller 8 is arranged inside the mixing pot body 4. The sealing cover 5 is detachably installed on the top of the mixing pot body 4.
