[0042] The height of the guide plate 14 gradually increases from the center of the top plate 11 to the guide block 13.

[0043] Optionally, an arc plate A15 located on the base plate 12 is fixedly installed on one side of the flow guiding assembly, and an arc plate B16 located on the base plate 12 is fixedly installed on the other side of the flow guiding assembly.

[0044] A semi-elliptical nozzle 17 is formed between the baffle 131 and the adjacent guide block 13.

[0045] like Figure 1-2 As shown, this utility model provides a centrifugal atomizing device, which has a base 3, wherein a movable block 4 is slidably connected above the base 3, an atomizing disc body 1 is provided at the front end of the base 3, and a feed box 2 is provided at the front end of the movable block 4.

[0046] The bottom end of the feed inlet 10 is rotatably connected to the feed tube 21, and the top end of the feed tube 21 is inserted into the bottom end of the feed box 2.

[0047] The feed box 2 has a feeding port 20, and a screw rod 22 is rotatably connected inside the feed box 2. The lower end of the screw rod 22 extends to the bottom end of the guide tube 21.

[0048] Optionally, in the above technical solution, the base 3 is fixedly connected to the guide tube 21, and the moving block 4 is fixedly connected to the feed box 2.

[0049] Optionally, in the above technical solution, a downward-extending threaded groove is provided at the center of the top of the base 3, and a screw 31 is threadedly connected inside the threaded groove.

[0050] A drive motor B41 is fixedly installed in the middle of the bottom wall of the movable block 4. The output shaft of the drive motor B41 extends downward and its end is connected to the screw 31 through a coupling.

[0051] Optionally, in the above technical solution, two strip-shaped grooves are symmetrically opened on the base 3 about the screw 31, and guide rods 42 are slidably connected in each strip-shaped groove;

[0052] The upper end of the guide rod 42 is fixedly installed on the bottom wall of the movable block 4.

[0053] Furthermore, a drive motor A23 is fixedly installed in the middle of the top wall of the feed box 2. The output shaft of the drive motor A23 extends downward, penetrates the top wall of the feed box 2, and is connected to the screw rod 22 through a coupling; wherein, the inside of the guide pipe 21 is connected to the inside of the screw rod 22.

[0054] Furthermore, a high-speed rotating motor 32 is provided at the lower end of the atomizing disc body 1. The output axis of the high-speed rotating motor 32 extends upward and is connected to the middle of the bottom wall of the atomizing disc body 1. The high-speed rotating motor 32 is fixedly connected to the base 3.

[0055] Furthermore, the shape of the nozzle 12 is half of an ellipse cut vertically;

[0056] Furthermore, each reverse flow track 13 extends from the center of the atomizing disc body 1 to the edge; and the "S" shape of the reverse flow track 13 enables the raw material to flow in both forward and reverse directions.

[0057] The base 3 has a counterweight at its bottom, and the length of the screw 32 is greater than the length of the spiral rod 22.

[0058] Specifically, the stop block 131 changes the direction in which the liquid is ejected from the guide rail 18; that is, the guide rail 18 itself is at a clockwise angle, while the stop block 131 causes the nozzle 17 to be at a counterclockwise angle.

[0059] Among them, the arc plate A15 and the arc plate B16 are symmetrically distributed in a guide track 18. The arc-shaped bottom facilitates the outflow of the liquid medicine and prevents the liquid medicine from remaining in the bending structure.

[0060] Working principle:

[0061] When the atomizing disc body 1 is working, the screw 31 is completely located inside the base 3, and at this time the guide tube 21 is in contact with the feed box 2 (e.g. Figure 1 Start the drive motor A23 to make it rotate the screw rod 22, and feed the raw material into the feed box 2 through the feed port 20. The screw rod 22 rotates clockwise and drives the raw material to move towards the feed port 10.

[0062] The high-speed rotating motor 32 is started to drive the atomizing disc body 1 to rotate in place. Under the action of high-speed rotation, centrifugal force is generated. The raw material enters the atomizing disc body 1 through the guide pipe 21 and the feed port 10. Under the action of the rotation of the atomizing disc body 1, the raw material passes through the guide track 18 and the spray port 17 in an orderly manner and is thrown out at high speed to form atomized particles. The material sprayed from each spray port 12 can be dried and atomized evenly.

[0063] When cleaning is required: Start the drive motor B41 to drive the screw 31 to rotate. The rotation of the screw 31 causes it to move upward relative to the base 3. Under the action of the guide rod 42, the moving block 4 rises linearly, thereby driving the feed box 2 to move the drive motor A23 and the screw 22 upward until the screw 22 is completely removed from the guide tube 21. At this time, a part of the screw 31 is still located in the base 3 (e.g., Figure 2 This facilitates the separate cleaning of the feed tube 21, the spiral rod 22, and the atomizing disc body 1.

[0064] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
