[0015] Compared with the prior art, the beneficial effects of this utility model are: this rotary kiln for zinc oxide production, which can uniformly feed materials, facilitates the even pouring of raw materials into the device during use, preventing material accumulation and thus avoiding affecting the oxidation efficiency of the device, thereby improving the processing efficiency. Simultaneously, it facilitates the stirring of raw materials and reducing agents during use, ensuring sufficient contact and oxidation between the raw materials and reducing agents within the device, improving the processing quality and resulting in better performance. Specifically, as shown below:

[0016] 1. The second drive motor drives the mounting block to rotate on the upper side of the machine body, so that the mounting block pushes the stirring rod to stir the raw materials and reducing agent, which facilitates the thorough mixing of the raw materials and reducing agent and improves the processing quality of the device;

[0017] 2. The third drive motor, in conjunction with the push rod, pushes the mixed raw material to the left at a uniform speed and into the interior of the machine body. This prevents the raw material from accumulating on the anti-slip plate surface, thus avoiding the accumulation of raw material and affecting the heating and oxidation efficiency of the device, thereby improving the processing efficiency of the device.

[0018] 3. The first drive motor, in conjunction with the drive disc, pushes the connecting teeth and the first mounting bracket to rotate along the first guide ring and the second guide ring inside the machine body shell, so that the anti-slip plate can perform anti-slip treatment on the raw material, preventing the raw material from shifting position on the inside of the anti-slip plate due to rotation, thereby improving the processing efficiency of the device.

[0019] 4.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a rotary kiln for zinc oxide production capable of uniform material feeding, comprising: a machine body shell 1, and a discharge port 17 disposed on the right side of the machine body shell 1, and further comprising:

[0028] Fuel inlet 2 is installed in the middle of the outer casing 1. A fuel storage tank 3 is provided on the upper side of fuel inlet 2. A flamethrower 4 is provided on the upper side of fuel storage tank 3. A flame nozzle 5 is provided on the outer side of flamethrower 4. A first mounting bracket 6 is provided at the lower end of flame nozzle 5. A connecting tooth 7 is provided at the lower end of first mounting bracket 6. A drive disk 8 is provided on the right side of connecting tooth 7. A first drive motor 9 is provided on the right side of drive disk 8. A first guide ring 10 is provided on the outer side of first mounting bracket 6. A second guide ring 11 is provided on the inner side of first mounting bracket 6. A valve 14 is provided on the left side of outer casing 1. A trapping net 15 is provided on the right side of valve 14. A collection bottle 16 is provided at the lower end of trapping net 15. A stirring assembly 18 is provided on the upper side of outer casing 1. A pusher rod 19 is provided at the lower end of stirring assembly 18. A third drive motor 20 is provided on the right side of pusher rod 19. This constitutes a complete rotary kiln for zinc oxide production.

[0029] like Figure 1 , Figure 2 and Figure 5As shown, the stirring assembly 18 includes a second mounting bracket 1801 mounted on the upper side of the outer casing 1. A second drive motor 1802 is disposed in the middle of the second mounting bracket 1801, and a mounting block 1803 is disposed at the lower end of the second drive motor 1802. A stirring rod 1804 is disposed on the outer side of the mounting block 1803. The stirring rod 1804 is engaged with the mounting block 1803, and the stirring rod 1804 is symmetrically arranged about the central axis of the mounting block 1803. When raw materials and reducing agents are poured into the upper side of the outer casing 1, the second drive motor 1802 drives the mounting block 1804 to move. The mounting block 1803 rotates on the upper side of the outer shell 1, causing the mounting block 1803 to push the stirring rod 1804 to stir the raw materials and reducing agent, which facilitates the thorough mixing of the raw materials and reducing agent and improves the processing quality of the device. Furthermore, the third drive motor 20 drives the pusher rod 19 to rotate on the upper side of the outer shell 1, so that the pusher rod 19 pushes the mixed raw materials to the left at a uniform speed and moves them into the interior of the outer shell 1, avoiding the accumulation of raw materials on the surface of the anti-slip plate 13, thus preventing the accumulation of raw materials from affecting the heating and oxidation efficiency of the device and improving the processing efficiency of the device.

[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the drive disc 8 and the connecting teeth 7 are meshed with each other. The first mounting bracket 6 on the upper side of the connecting teeth 7 has a circular cross-section, and the first guide ring 10 has a "T" shaped longitudinal section. The first mounting bracket 6, the first guide ring 10, and the second guide ring 11 are all rotatably arranged relative to each other. A positioning block 12 is provided on the upper side of the first mounting bracket 6, and an anti-slip plate 13 is provided on the upper side of the positioning block 12. The anti-slip plate 13 is engaged with the positioning block 12. The intercepting net 15 and the collection bottle 16 are engaged with the outer shell 1 of the machine body, and the discharge port 17 is rotatably arranged relative to the outer shell 1 of the machine body. The first drive motor 9 drives the drive disc 8 to rotate inside the outer shell 1 of the machine body, causing the drive disc 8 to push the connecting teeth 7. The first mounting frame 6 rotates along the first guide ring 10 and the second guide ring 11. At this time, the first mounting frame 6 drives the anti-slip plate 13 and the mixed raw material on its upper side to rotate inside the outer shell 1 of the machine body. This makes the anti-slip plate 13 anti-slip, preventing the raw material from shifting position on the inner side of the anti-slip plate 13 due to rotation, thus improving the processing efficiency of the device. Furthermore, after the oxidation and reduction are completed, the valve 14 is opened, allowing the airflow to carry the reduced zinc oxide dust to the left. At this time, the interception net 15 intercepts the zinc oxide dust in the airflow, causing the zinc oxide dust to fall downwards into the inside of the collection bottle 16, which facilitates the interception and collection of zinc oxide dust by the device, thus improving the efficiency of the device.
