[0025] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0027] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

[0028] Referring to Figures 1 to 4 , it is the first embodiment of the present invention. This embodiment provides a charging device for a calcining rotary kiln used in the processing of preparing calcium aluminate powder from aluminum ash, including an installation unit 1, including an installation frame 11, and a telescopic component 12 provided at the top of the installation frame 11.

[0029] It should be noted that four telescopic components 12 are fixedly connected to the top of the installation frame 11, and the telescopic component 12 can achieve linear telescoping.

[0030] The blanking unit 2 includes a casing 21 rotatably arranged at the top end of the telescopic assembly 12, a connecting assembly 22 arranged on one side of the casing 21, a blanking motor 23 arranged on one side of the casing 21, a first spiral blade 24 arranged at the output end of the blanking motor 23, and a mounting bracket 25 arranged in the inner cavity of the casing 21;

[0031] The first spiral blade 24 extends into the inner cavity of the connecting assembly 22 through the mounting bracket 25.

[0032] It should be noted that the casing 21 is installed at the top end of the telescopic assembly 12, and the casing 21 is rotatably connected to the telescopic assembly 12. A connecting assembly 22 is fixedly connected to one side of the casing 21. The casing 21 is connected to the rotary kiln through the connecting assembly 22. A blanking motor 23 is fixedly connected to one side of the casing 21. A mounting bracket 25 is fixedly connected inside the casing 21. The inner cavity of the mounting bracket 25 is rotatably connected to a first spiral blade 24. The first spiral blade 24 and the blanking motor 23 are connected by a coupling. The first spiral blade 24 extends into the inner cavity of the connecting assembly 22 and extends out from the connecting assembly 22.

[0033] The conveying assembly 3 is arranged below the casing 21; a corrugated pipe 211 is fixedly connected to the top end of the casing 21; the bottom end of the casing 21 extends into the inside of the feed inlet 32.

[0034] It should be noted that a conveying assembly 3 is arranged below the casing 21 for transporting the finished calcium aluminate out of the device. And the bottom end of the casing 21 extends into the inside of the feed inlet 32 to prevent the leakage of calcium aluminate. And a corrugated pipe 211 is fixedly connected to the top end of the casing 21. By providing the corrugated pipe 211, it can be ensured that when the height and angle of the casing 21 are adjusted, it will not affect the connection between the casing 21 and the waste gas treatment device.

[0035] During use, it is connected to the rotary kiln through the connecting assembly 22, and then one end of the corrugated pipe 211 is connected to the waste gas treatment device. During installation, it is necessary to ensure that the first spiral blade 24 extends into the rotary kiln. During the installation process with the rotary kiln, the angle and height of the casing 21 are adjusted by the telescopic movement of the telescopic assembly 12, so that it is connected to the rotary kiln through the connecting assembly 22;

[0036] Start the blanking motor 23. The blanking motor 23 drives the first spiral blade 24 to rotate through the coupling. Utilizing the characteristics of the spiral blade, the calcium aluminate in the discharging area of the rotary kiln is transported into the casing 21, and then falls into the conveying assembly 3 and is output from the device by the conveying assembly 3.

[0037] In summary, the calcium aluminate accumulated inside the rotary kiln can be removed by the spiral blade to prevent blockage caused by the condensation of molten aluminum. Moreover, both the angle and height of the casing 21 can be adjusted. When it is necessary to adjust the angle of the rotary kiln to increase or decrease the reaction time, the casing 21 can be adapted accordingly.

[0038] As Figures 1 to 4 shown, as an alternative embodiment: The telescopic assembly 12 includes a column 121 disposed on the upper surface of the mounting frame 11, a telescopic rod 122 slidably disposed on the column 121, a connecting head 123 rotatably disposed at the top of the telescopic rod 122, and a cylinder 124 disposed between the column 121 and the telescopic rod 122;

[0039] It should be noted that the column 121 is fixedly welded to the top of the mounting frame 11 and is located on both sides of the casing 21. A telescopic rod 122 is slidably connected to the top of the column 121. A cylinder 124 is disposed between the telescopic rod 122 and the column 121. The top of the telescopic rod 122 and the casing 21 are rotatably connected through the connecting head 123. By controlling the expansion and contraction of the cylinder 124, the height and angle of the casing 21 can be adjusted.

[0040] As Figure 3 shown, as an alternative embodiment: The connecting assembly 22 includes a feeding pipe 221, a fixed pipe 222 disposed at one end of the feeding pipe 221, and a limiting member 223 rotatably disposed on the outer wall of the feeding pipe 221;

[0041] The limiting member 223 and the fixed pipe 222 are fixedly connected;

[0042] The limiting member 223 includes an arc-shaped clamping plate 2231, a limiting ring 2232 disposed on the outer wall of the feeding pipe 221, and a connecting column 2233 disposed on one side of the arc-shaped clamping plate 2231.

[0043] It should be noted that the feeding pipe 221 is connected to the rotary kiln through bolts. A fixed pipe 222 is inserted into the other end of the feeding pipe 221. A limiting ring 2232 is formed on the outer wall of the feeding pipe 221. Two arc-shaped clamping plates 2231 form a closed loop and rotate on the limiting ring 2232. A connecting column 2233 is fixedly connected to the arc-shaped clamping plate 2231. By passing the bolt through the fixed pipe 222 and screwing it into the connecting column 2233, the rotational connection of the fixed pipe 222 on the feeding pipe 221 is achieved. The other end of the fixed pipe 222 is fixedly connected to the casing 21. When the rotary kiln rotates, the feeding pipe 221 will rotate with the rotary kiln, while the fixed pipe 222 rotates relative to the feeding pipe 221, realizing the connection between the casing 21 and the rotary kiln, and not affecting the rotation of the rotary kiln. The connection between the two is tighter, and the problem of leakage of calcium aluminate through the connection gap can be prevented.

[0044] As Figures 1 to 5As shown, as an alternative embodiment: The conveying assembly 3 includes a conveying pipe 31 disposed on the mounting frame 11, a feed inlet 32 disposed at the top of the conveying pipe 31, a discharge outlet 33 disposed at the bottom of the conveying pipe 31, a second spiral blade 34 disposed in the inner cavity of the conveying pipe 31, and a conveying motor 35 disposed on the outer wall of one side of the conveying pipe 31;

[0045] The input end of the second spiral blade 34 is fixedly connected to the output end of the conveying motor 35.

[0046] It should be noted that the conveying pipe 31 is fixedly installed on the mounting frame 11, and a feed inlet 32 is provided at the top of the conveying pipe 31, and a discharge outlet 33 is provided at the bottom. A second spiral blade 34 is rotatably connected in the inner cavity of the conveying pipe 31 for conveying the calcium aluminate that has fallen into the conveying pipe 31. A conveying motor 35 is fixedly connected to the outer wall of one end of the conveying pipe 31, and the conveying motor 35 and the second spiral blade 34 are connected by a coupling.

[0047] During use, the calcium aluminate falls from the feed inlet 32 into the conveying pipe 31, and the conveying motor 35 drives the second spiral blade 34 to rotate, driving the calcium aluminate to move towards the discharge outlet 33 and finally falling out of the device from the discharge outlet 33.
