Description

Technical Field

[0001] The utility model relates to the technical field of high-speed atomizer equipment accessories, in particular to a pre-dispersed atomization disc. Background Art

[0002] The centrifugal atomizer generally uses a high-speed motor to drive the gearbox, which is transmitted to the main shaft after the speed change. The atomizing disk is installed at the lower end of the main shaft. The material enters the distributor from the top to the bottom of the feed pipe. The distributor evenly distributes the liquid into the atomizing disk for centrifugal atomization to obtain a product with smaller particles. There is a discharge hole on the side of the atomizing disk. The material moves outward under the centrifugal effect and sprays outward at the discharge hole to achieve atomization. The actual atomization process is at the discharge hole, but some materials have serious agglomeration phenomenon, and the material is not easy to atomize evenly, resulting in poor atomization effect. Utility Model Content

[0003] Technical problems to be solved by utility models

[0004] In view of the technical problem of how to atomize materials more evenly, the utility model provides a pre-dispersed atomizing disk, which can atomize materials more evenly and improve the atomization effect.

[0005] Technical Solution

[0006] In order to solve the above problems, the technical solution provided by the utility model is:

[0007] A pre-dispersed atomization disk comprises a disk body, wherein a feed port is provided on the top of the disk body, wherein the feed port is connected to a cavity in the disk body, wherein an inclined protrusion and a pre-dispersed groove are provided directly below the feed port, wherein the inclined protrusion is located on a vertical wall in the disk body, wherein the pre-dispersed groove is located at the bottom of the cavity, wherein the groove surface of the pre-dispersed groove is an inclined surface, and wherein the inclined surface forms an acute angle with the vertical wall.

[0008] Enhanced material dispersion: The design of the oblique convex and pre-dispersed groove makes the material entering the cavity change direction and speed after colliding with the oblique convex, which helps the mutual collision and dispersion of material particles, reduces the aggregation of large particles, and thus achieves a more uniform material distribution.

[0009] Optimize the atomization path: The setting of the pre-dispersal trough, especially the structure in which its inclined surface forms an acute angle with the vertical wall, changes the direction and trajectory of material flow, causing the material to collide back and forth between the pre-dispersal trough and the vertical wall to achieve pre-dispersal, increasing the opportunity and time for the material to contact with the air or other atomizing media, which is conducive to further refining the material particles and improving the atomization efficiency.

[0010] Improve atomization quality: Since the surface of the pre-dispersal trough is an inclined surface, when the material slides down the inclined surface under the action of gravity, it is not only accelerated by the friction of the inclined surface to disperse, but also can avoid material accumulation caused by direct vertical fall, ensuring that the material has been fully dispersed before entering the subsequent atomization stage, which is conducive to the formation of smaller and more uniform droplets and improves the atomization effect.

[0011] Reduce energy consumption and wear: By pre-dispersing the material before it enters the high-speed rotating atomization area, the direct impact of high-speed rotation on the material is reduced, the energy consumption during the atomization process is reduced, and the wear of the atomization disk and its components is reduced, thereby extending the service life of the equipment.

[0012] Optionally, the inclined surface forms an angle of 30° to 90° with the vertical wall.

[0013] The angle between the inclined surface and the vertical wall is greater than 30°. Too small an angle will increase the difficulty of centrifuging the material and weaken the atomization effect.

[0014] Optionally, the oblique protrusion is perpendicular to the inclined surface.

[0015] After the material falls along the inclined convex surface, it forms a vertical impact surface with the inclined surface, which is beneficial to improve the pre-dispersion effect of the material.

[0016] Optionally, the end of the oblique projection is provided with a straight angle.

[0017] Avoid the material falling at an angle that is too steep, so that the material cannot fall onto the pre-dispersal chute, affecting the pre-dispersal effect.

[0018] Optionally, the groove surface and the vertical wall of the pre-breaking groove are both provided with a coating.

[0019] The groove surface of the pre-dispersed groove and the vertical wall are pre-dispersed impact surfaces, and the coating is beneficial to protecting the groove surface of the pre-dispersed groove and the vertical wall, thereby extending the service life.

[0020] Optionally, the coating is a cemented carbide coating.

[0021] The cemented carbide coating has strong impact resistance and is beneficial to prolonging the service life.

[0022] Optionally, the coating is an anti-corrosion coating.

[0023] The anti-corrosion coating has strong anti-corrosion performance, while some materials are highly corrosive, which is beneficial to extend the service life of the atomizer disc.

[0024] Optionally, the disc body is an integrally formed structure.

[0025] One-piece molding usually provides better structural strength and stability, because the material forms a continuous whole during the molding process without seams or welding points, so it is not easy to crack or separate during use. For applications that require good sealing, the one-piece molding structure can effectively avoid leakage problems caused by improper treatment of seams or connections, ensuring the reliability of equipment operation. One-piece molding reduces subsequent assembly steps, simplifies the production process, reduces production costs, and also reduces quality problems that may be caused by improper assembly. Since it is a one-time molding, the production cycle is relatively shortened, and it is easy to realize automated production, further improving production efficiency. The one-piece molding structure reduces the relative movement and wear between components, reducing maintenance frequency and costs.

[0026] Beneficial Effects

[0027] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0028] The technical solution provided by the utility model is provided with an inclined convex and a pre-dispersing groove, so that the material entering the cavity changes direction and speed after colliding with the inclined convex, which is conducive to mutual collision and dispersion between material particles, reduces the aggregation of large particles, and thus achieves a more uniform material distribution. The structure in which the inclined surface and the vertical wall form an acute angle changes the direction and trajectory of the material flow, so that the material collides back and forth between the pre-dispersing groove and the vertical wall, achieves pre-dispersing, increases the opportunity and time for the material to contact with the air or other atomizing media, and is conducive to further refining the material particles and improving the atomization efficiency. Since the groove surface of the pre-dispersing groove is an inclined surface, when the material slides down the inclined surface under the action of gravity, it is not only accelerated to disperse by the friction of the inclined surface, but also can avoid the accumulation of materials caused by direct vertical falling, ensuring that the material has been fully dispersed before entering the subsequent atomization stage, which is conducive to the formation of finer and more uniform droplets, and improves the atomization effect.
