Description

Technical Field

[0001] This utility model relates to the field of centrifugal stirring blade technology, specifically a centrifugal stirring blade for preparing zirconia. Background Technology

[0002] Zirconia is a ceramic material with high melting point, high hardness, corrosion resistance and excellent mechanical properties. It is widely used in industrial, medical and electronic fields. Zirconia can be prepared by hydrothermal method, coprecipitation method, sol-gel method, etc. Among them, coprecipitation method requires mixing zirconium salt solution with stabilizer and stirring the reaction with centrifugal stirrer to generate uniform precipitate.

[0003] Although existing centrifugal agitator blades for zirconia processing in paper cups offer many advantages, the following problems still exist: Traditional radial flow impellers create a flow velocity dead zone in the central axis region, causing high-solids-content zirconia particles to accumulate and entangle, leading to uneven mixing and motor overload. Secondly, fixed-gap impellers cannot remove the sediment layer on the tank wall, forming a hardened crust, increasing thermal resistance and contaminating the slurry. Utility Model Content

[0035] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0036] This utility model provides an overall structural schematic diagram of an embodiment of a centrifugal stirring blade for preparing zirconia, including:

[0037] Please see Figures 1-5 This embodiment of a centrifugal stirring blade for preparing zirconia processing includes a flange 100, a drive shaft 200 driven by bolts at the bottom of the flange 100, and a plurality of blade groups 400 welded to the outer circumference of the drive shaft 200.

[0038] The blade assembly 400 includes two stirring blades, one of which rotates in the same direction as the other and is symmetrically distributed around the axis of the drive shaft 200. The circumferential phase difference between the starting points of the two stirring blades is 180 degrees.

[0039] The bottom of the drive shaft 200 is fixedly connected to the hub 500 by bolts. The outer side wall of the hub 500 is fixedly connected to the mounting block 610 by bolts. The mounting block 610 includes a mounting seat 600. The side wall of the mounting seat 600 is integrally formed and connected to two limit blocks 630. The side wall of the mounting seat 600 is inserted into a pin 640. The outer circumferential wall of the pin 640 is hinged to a scraper arm 320 assembly.

[0040] The scraper arm 320 assembly includes a bracket 310, with the scraper arm 320 integrally connected to the top of the bracket 310, and a scraper blade 330 fixedly connected to the outer side wall of the scraper arm 320.

[0041] It is worth noting that, in order to facilitate the installation and fixing of the drive shaft 200 and the connection of an external drive motor, the flange 100 has a ring structure to facilitate connection with the drive shaft 200. The top of the flange 100 has multiple connection holes 110 to facilitate installation by bolts.

[0042] Next, to facilitate the connection between the drive shaft 200 and the flange 100 and the hub 500, specifically, the top of the drive shaft 200 is integrally connected to a connecting rod 1, the outer circumference of the connecting rod 1 is sleeved with the flange 100, and the bottom of the drive shaft 200 is integrally connected to a connecting rod 2, the outer circumference of the connecting rod 2 is sleeved with the hub 500.

[0043] Meanwhile, to facilitate the connection of the scraper arm assembly 300, specifically, the hub 500 has a conical structure. The conical structure allows the load at the root of the stirring blade to be gradually transferred along the generatrix, reducing the stress concentration factor. The outer circumference of the hub 500 is integrally formed with multiple tenons 510 to facilitate the connection of the mounting base 600.

[0044] Furthermore, to facilitate the connection of the scraping components, specifically, the side wall of the mounting base 600 is integrally formed with a mortise block 620, the side wall of the mortise block 620 is inserted with a tenon block 510, and external bolts or pins are used for fastening. The limiting block 630 has a triangular structure.

[0045] It is worth noting that, in order to scrape the material by the scraping component 300, specifically, the top of the bracket 310 is inserted with a pin 640. When the drive shaft 200 rotates, the bracket 310 naturally drives the scraper arm 320 and the scraper blade 330 to scrape the material through centrifugal force. When the drive shaft 200 stops rotating, it naturally deflects and separates with the limit block 630. The scraper blade 330 has a triangular structure, which improves the scraping efficiency.

[0046] Finally, to improve mixing efficiency and the service life of the mixing blades, specifically, the mixing blades have a spiral structure, including a blade body 410, a blade head 420 integrally formed and connected to the side wall of the blade body 410, and a blade tail 430 integrally formed and connected to the side wall of the blade body 410. The blade tail 430 is welded to the drive shaft 200. The blade head 420 has an arc-shaped structure, which effectively distributes contact stress evenly, making the wear of the blade head 420 uniform, while also effectively reducing shear mutation, reducing particle breakage rate, and generating adhesion residue, thus improving the efficiency of clearing the boundary layer of the tank wall. The blade tail 430 has a flat structure, which not only provides a high-rigidity welding surface and reduces the amplitude of the vortex load, but also eliminates tail vortex energy consumption, maintains the laminar boundary layer, and improves the stability of the center return flow.

[0047] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0048] Combination Figures 1-5 The specific usage process of a centrifugal stirring blade for preparing zirconia processing according to this embodiment is as follows:

[0049] 1: When using this centrifugal stirring blade, it is installed and fixed in the designated position with bolts through the multiple connection holes 110 on the top of the flange 100. Then, the drive shaft 200 is connected to an external drive motor through a coupling or other connecting parts. Then, the centrifugal stirring blade can be used to centrifuge and stir the zirconium oxide material to be processed.

[0050] 2: When the blade assembly 400 rotates and stirs the material, the two symmetrically distributed double-helix stirring blades rotating in the same direction form an axial flow scouring at the central axis, which completely eliminates material accumulation. When the material moves along the stirring blades to the hub 500, it naturally expands outward through the conical structure of the hub 500, eliminating concentrated stress.

[0051] 3: When the blade assembly 400 rotates and stirs, the support 310 and scraper arm 320 naturally unfold by centrifugal force to scrape the inner wall of the mixing tank. After stirring is completed, the support 310 swings naturally through the pin 640 of the mounting base 600 and is limited by the limit block 630 to disengage from the inner wall of the mixing tank. At this time, the scraper 330 can also be disassembled and maintained for easy maintenance.

[0052] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
