Description

Technical Field

[0001] This utility model relates to the technical field of hafnium oxide powder storage devices, and in particular to a stirring structure for a hafnium oxide powder anti-agglomeration storage tank. Background Technology

[0002] Hafnium oxide, an inorganic compound composed of hafnium and oxygen, possesses unique physical properties and chemical stability, making it indispensable in numerous high-tech fields such as electronic components, optical devices, advanced ceramics, high-efficiency catalysts, and high-temperature resistant materials. However, a significant issue in the storage of hafnium oxide powder is the tendency for powder particles to agglomerate. This not only affects the uniformity and dispersibility of the powder but may also adversely impact subsequent processing performance and the quality of the final product.

[0003] Therefore, specialized storage tanks for storing hafnium oxide powder need to be specially designed with an efficient anti-agglomeration stirring mechanism. Unfortunately, some storage tanks currently on the market use relatively simple stirring structures, often relying solely on a single stirring rod for mechanical stirring. This basic design is inadequate for dealing with easily agglomerated materials like hafnium oxide powder, making it difficult to achieve thorough mixing between different layers of the powder and effectively break up agglomerates, thus limiting the storage effect and the full potential of the powder's performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a stirring structure for a hafnium oxide powder anti-agglomeration storage tank.

[0005] The technical implementation scheme of this utility model is as follows: a stirring structure for a hafnium oxide powder anti-agglomeration storage tank, including a bottom plate, a lifting assembly, a storage tank, a cover plate, a feed pipe, a valve pipe, a stirring assembly, and a drying assembly. The lifting assembly is provided on the top of the bottom plate, the storage tank is provided on the lifting assembly, the cover plate is provided on the top of the storage tank, the feed pipe is fixedly connected to the front side of the cover plate, the valve pipe is provided at the bottom of the storage tank, the stirring assembly is provided on the top of the lifting assembly for stirring the hafnium oxide powder in the storage tank, the lifting assembly is used to drive the storage tank to move up and down, and a drying assembly for drying the hafnium oxide powder is provided together on the stirring assembly and the cover plate.

[0006] Optionally, the lifting assembly includes guide rails, sliders, and hydraulic cylinders.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0018] Example: A stirring structure for a hafnium oxide powder anti-agglomeration storage tank, such as... Figures 1-4 As shown, the system includes a base plate 1, a lifting assembly, a storage tank 31, a cover plate 32, a feed pipe 33, a valve pipe 34, a stirring assembly, and a drying assembly. The lifting assembly is located on the top of the base plate 1, and the storage tank 31 is mounted on the lifting assembly. The cover plate 32 is bolted to the top of the storage tank 31, and the feed pipe 33 is welded to the front side of the cover plate 32. The valve pipe 34 is welded to the bottom of the storage tank 31 and communicates with the internal space of the storage tank 31 for feeding hafnium oxide powder. The stirring assembly is located on the top of the lifting assembly for stirring the hafnium oxide powder in the storage tank 31. The lifting assembly is used to move the storage tank 31 up and down. The stirring assembly and the cover plate 32 are both equipped with a drying assembly for drying the hafnium oxide powder.

[0019] like Figure 1 As shown, the lifting assembly includes a guide rail 2, a slider 21, and a hydraulic cylinder 22. The guide rail 2 is welded and fixed on both the left and right sides of the top of the base plate 1. The slider 21 is slidably connected to both guide rails 2. The storage tank 31 is fixed between the two sliders 21 by welding. The hydraulic cylinder 22 is fixedly installed on both the left and right sides of the top of the base plate 1 by bolts. The piston rods of the two hydraulic cylinders 22 are fixedly connected to the two sliders 21 respectively.

[0020] like Figure 1 and Figure 2 As shown, the stirring assembly includes a horizontal plate 41, a mounting block 42, a stirring shaft 43, a motor 44, and stirring rods 45. The horizontal plate 41 is fixed between the tops of the two guide rails 2 by bolts. The mounting block 42 is welded and fixed in the middle of the horizontal plate 41. The stirring shaft 43 is rotatably connected in the mounting block 42. The motor 44 is mounted on the top of the horizontal plate 41 by bolts. The output shaft of the motor 44 is fixedly connected to the upper end of the stirring shaft 43. The middle and lower part of the stirring shaft 43 passes through the cover plate 32 and extends into the storage tank 31. Five stirring rods 45 are fixed to the middle and lower part of the stirring shaft 43 at intervals by bolts.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the drying assembly includes heating rods 51, exhaust pipes 52 and filter screens 53. Heating rods 51 are embedded on both sides of the five stirring rods 45. Exhaust pipes 52 are welded and fixed to the right side of the cover plate 32. Filter screens 53 are provided at the upper end of exhaust pipes 52.

[0022] In actual use, the operator first operates the two hydraulic cylinders 22 to retract their piston rods, lowering the storage tank 31 to a lower position. This design facilitates the operator adding hafnium oxide powder into the storage tank 31 through the feed pipe 33. After the hafnium oxide powder has been added, the operator starts the motor 44, which then drives the stirring shaft 43 to rotate, thereby driving the stirring rod 45 to stir the hafnium oxide powder in the tank, effectively preventing powder agglomeration. While the stirring operation is in progress, the operator starts the two hydraulic cylinders 22 again, controlling their piston rods to repeatedly extend and retract. This operation causes the storage tank 31 to reciprocate, raising and lowering the stirring rod. Stirring rod 45 can reach hafnium oxide powder at different heights within storage tank 31, achieving all-round, multi-layered stirring, thereby significantly improving the stirring effect. At the same time, the operator powers on heating rod 51, which quickly heats up and transfers heat to stirring rod 45. During the stirring of hafnium oxide powder, stirring rod 45 dries the moisture in the powder through heat conduction. The generated water vapor rises naturally and is discharged outside the tank through exhaust pipe 52, ensuring that hafnium oxide powder always remains dry and further preventing agglomeration. After completing the above work, the operator takes two sealing caps and seals the feed pipe 33 and exhaust pipe 52 respectively.

[0023] like Figure 3 and Figure 4 As shown, it also includes a cutting plate 6, and the cutting plate 6 is symmetrically welded and fixed on both sides of the five stirring rods 45.

[0024] By setting the cutting plate 6, when the stirring shaft 43 stirs the hafnium oxide powder, the cutting plate 6 can cut into the agglomerated powder blocks and effectively break them up, thereby further improving the dispersion and uniformity of the powder.

[0025] like Figure 2 and Figure 3 As shown, it also includes scrapers 7. Scrapers 7 are welded and fixed between the left and right ends of the five stirring rods 45. Both scrapers 7 are in contact with the inner wall of the storage tank 31.

[0026] By setting up scraper 7, during the process of stirring hafnium oxide powder by rotating stirring rod 45, scraper 7 will simultaneously scrape and clean the inner wall of storage tank 31, effectively preventing hafnium oxide powder from adhering to the inner wall of storage tank 31.

[0027] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
