Description

Technical Field

[0001] This utility model relates to the field of dispersion disc technology, specifically a wear-resistant and corrosion-resistant dispersion disc structure. Background Technology

[0002] In industrial fields such as coatings, inks, and lithium battery slurry preparation, dispersion discs are widely used as core components in equipment such as high-speed dispersers and grinding mills, and their performance directly affects the material dispersion efficiency and product quality.

[0003] In existing technologies, improving wear resistance often comes at the cost of sacrificing corrosion resistance. For example, while tungsten carbide spraying can increase hardness, it is prone to failure in corrosive environments due to the propagation of microcracks; although high-entropy alloy coatings have both wear and corrosion resistance, their multi-layer structure design is complex and the manufacturing cost is high, making them difficult to apply on a large scale.

Detailed Implementation

[0015] This utility model embodiment provides a wear-resistant and corrosion-resistant dispersion disc structure, such as Figure 1-4As shown, the system includes a dispersion disk base 101. A central connecting shaft 111 is fixedly provided at the center of the top of the dispersion disk base 101. Several main dispersion teeth 102 arranged in a ring array are fixedly provided on the outer end face of the central connecting shaft 111. Several oblique dispersion blades 112 arranged in a ring array are fixedly provided at the bottom of the dispersion disk base 101. The oblique dispersion blades 112 are inclined. Several guide plates 110 are fixedly provided on the outer end face of the dispersion disk base 101. The guide plates 110 are arranged in a ring array and are staggered from the main dispersion teeth 102. Two guide inclined surfaces 109 are fixedly provided on the upper and lower end faces of the guide plates 110. The guide inclined surfaces 109 on both sides are symmetrical and inclined inward.

[0016] It should be further explained that the guide slope 109 is inclined to guide the dispersion of materials.

[0017] Furthermore, an auxiliary mounting plate 103 is provided at the center of the bottom of the dispersion plate base 101 to facilitate installation and connection.

[0018] Furthermore, a top connecting seat 104 is fixedly provided at the center of the top end of the central connecting shaft 111, and an upward-opening oblique dispersing blade 112 is provided inside the top connecting seat 104.

[0019] Furthermore, a vertical auxiliary mounting plate 103 is installed inside the obliquely dispersing blade 112, and a stacking plate 108 is installed on the outer end face of the auxiliary mounting plate 103. The stacking plate 108 is threadedly connected to the auxiliary mounting plate 103.

[0020] Furthermore, a connecting sleeve plate 106 is fixedly provided at the center of the stacking disk 108, and a number of auxiliary dispersing blades 107 are fixedly provided on the outer end face of the connecting sleeve plate 106, with the auxiliary dispersing blades 107 arranged in a ring array.

[0021] Furthermore, a limiting pressure plate 105 is fixedly provided at the top of the connecting sleeve plate 106, and the limiting pressure plate 105 and the top of the auxiliary mounting plate 103 have the effect of abutting and limiting.

[0022] The usage method of this solution is as follows: S1. The central connecting shaft 111 is reliably connected and fixed to the main drive shaft of the high-speed disperser or grinder via the top connecting seat 104 at its top.

[0023] If it is necessary to enhance the dispersion effect or adapt to materials of different viscosities, an auxiliary mounting plate 103 can be installed inside the inclined dispersion blade 112, and the stacking plate 108 can be screwed and fixed onto the auxiliary mounting plate 103 by threaded connection. The limit plate 105 ensures that the stacked plate 108 is firmly abutted against the top of the auxiliary mounting plate 103 to prevent loosening during operation; The auxiliary mounting plate 103 at the bottom of the distribution plate base 101 can be used to connect other auxiliary components or provide additional mounting positioning points.

[0024] S2. Apply a single-layer wear-resistant and corrosion-resistant alloy coating with high hardness and excellent corrosion resistance to all working surfaces that come into contact with materials, such as the dispersion disk base 101, main dispersion teeth 102, inclined dispersion blades 112, guide plate 110, guide inclined surface 109, stacked disk 108, and auxiliary dispersion blades 107. The coating is preferably a single-layer dense coating based on nickel-based alloys, cobalt-based alloys, or high-entropy alloys with specific compositions, and is prepared by processes such as thermal spraying, laser cladding, or vapor deposition. This avoids the complex design of multi-layer high-entropy alloy coatings in the prior art, significantly reduces the preparation difficulty and cost, and facilitates large-scale application; The alloy system is selected because it has excellent wear resistance and corrosion resistance. Strictly control the coating process parameters to ensure that the coating structure is dense, has low porosity, and is firmly bonded to the substrate, effectively inhibiting corrosive media from penetrating and eroding the substrate through microcracks or pores; All critical component surfaces that come into contact with materials are protected to ensure overall service life.

[0025] S3. Start the equipment and drive the dispersing disc to rotate at high speed; Add the coating, ink, lithium battery slurry, or other materials that need to be dispersed, mixed, or ground into the working chamber from above or to the side of the dispersion disc; Primary dispersion: The rotating main dispersion teeth 102 exert strong impact and shearing action on the material, performing preliminary crushing and dispersion; Meanwhile, the inclined dispersion blades 112, when rotated, generate strong axial flow force, which pushes the material to circulate violently in the vertical direction, preventing the material from stratifying or depositing at the bottom and promoting overall mixing uniformity. Guided flow and secondary dispersion: Under the action of centrifugal force, the material moves outward and passes through the guide plate 110 and the inwardly inclined guide slopes 109 on both sides. The inclined design of the guide slopes 109 plays a key guiding and converging role in the material flow. The guide slope 109 guides part of the outward material flow, changes its direction, generates more complex turbulence and deflection, increases the collision and shear frequency and path length between materials, thereby significantly improving dispersion efficiency and dispersion fineness. The staggered distribution of the guide vane 110 and the main dispersion tooth 102 avoids flow field interference and makes the flow guiding effect better.

[0026] S4. If the stacked disk 108 assembly is installed, the auxiliary dispersing blades 107 on it generate an additional shear flow field during rotation. This field works synergistically with the flow fields generated by the main dispersing teeth 102, the oblique dispersing blades 112, and the guide structure to form a multi-level, multi-directional composite dispersion region. This is particularly suitable for high-viscosity, high-solids-content materials that are difficult to disperse, such as lithium battery electrode slurries, achieving a finer dispersion effect. The modular design of the stacked disk 108 allows users to flexibly adjust the dispersion intensity according to actual needs.

[0027] S5. After long-term use, if the wear-resistant and corrosion-resistant coating on the local working surface is worn, thanks to the detachable threaded connection design of the stacked disc 108, it can be easily removed for local repair or replacement without replacing the entire dispersion disc. If the coating of the dispersion disk base 101 and its fixing components is severely worn, they can be disassembled as a whole for remanufacturing or replacement. The design of the auxiliary mounting disk 103 simplifies the disassembly process.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
