[0021] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0023] Please refer to Figures 1-4 , a rotary kiln for polyaluminum chloride production according to the present utility model includes a rotary kiln 1, a connection kit 2 is arranged on the outer side of the rotary kiln 1, a positioning member 4 that is adjusted to open and close by rotation is arranged on the outer side of the connection kit 2, the positioning member 4 is perpendicular to the surface of the connection kit 2, a tyre 5 that is inserted into the outer side of the connection kit 2 and docked with the positioning member 4 is arranged, and a bolt 7 for connecting and fixing with the tyre 5 is installed in the positioning member 4.

[0024] Please refer to Figure 2 , the connection kit 2 is fixedly connected to both ends of the surface of the rotary kiln 1 and is symmetrically distributed with the center of the rotary kiln 1 as the origin. The connection kit 2 is in a regular hexagon shape. A notch 3 is opened at one end of the outer side of the connection kit 2, and the notch 3 is annularly and equidistantly distributed with the center of the rotary kiln 1 as the center point. The regular hexagon setting of the connection kit 2 enables a flat cuboid to be formed after the notch 3 is opened on the surface for use in cooperation with the cuboid movable plate 41. When the movable plate 41 is closed inside the notch 3, it can be completely received in the notch 3. When the tyre 5 is not fixed, it can directly pass through the connection kit 2 and the movable plate 41 for disassembly operations without affecting the movement of the tyre 5 outside the connection kit 2.

[0025] Please refer to Figure 2 , the positioning member 4 includes a movable plate 41 and a through hole 42. The movable plate 41 is rotatably connected between the two sides of the inner wall of the notch 3. The movable plate 41 is perpendicular to the surface of the connection kit 2 and fits one end of the inner wall of the notch 3. One side of the movable plate 41 located inside the notch 3 is arc-shaped, and the center of the circle coincides with the rotation center of the movable plate 41. The thickness of the movable plate 41 is the same as the depth of the notch 3. The through hole 42 is opened in the center of the surface of the movable plate 41. When the movable plate 41 is unfolded for use, under the limitation of the rotation center and one end of the inner wall of the notch 3, the movable plate 41 will be vertically unfolded at one end of the inner wall of the notch 3. The vertically unfolded movable plate 41 provides a positioning effect for the tyre 5 installed on the outer side of the connection kit 2 and can be used for connecting and fixing the tyre 5. The arc-shaped side setting of the movable plate 41 rounds the corners, so that the movable plate 41 will not conflict with the notch 3 during the rotation process, ensuring the smoothness of the rotation path.

[0026] Please refer to Figure 1 , the tyre 5 is installed on the outer side of the connecting kit 2 and fits against the surface of the movable plate 41. Threaded holes 6 are provided on the surface of the tyre 5, which are annularly and equidistantly distributed with the centre of the tyre 5 as the centre point. The centre of the threaded hole 6 coincides with the centre of the through hole 42. The bolt 7 is inserted into the through hole 42 and is threadedly connected to the threaded hole 6. Supported by the unfolding of the movable plate 41, the tyre 5 can be connected to the movable plate 41 through the bolt 7 and fixed on the outer side of the connecting kit 2. The tyre 5 after being connected to the movable plate 41 restricts the rotation path of the movable plate 41, and the movable plate 41 cannot rotate, providing stable support for the tyre 5. The tyre 5 and the movable plate 41 interact with each other and cooperate with the connection of the bolt 7, so that the tyre 5 has good stability after being connected and fixed.

[0027] When it is necessary to disassemble the tyre 5, only the bolt 7 connecting the movable plate 41 and the tyre 5 needs to be disassembled, then the tyre 5 is moved away from the outer side of the connecting kit 2, and then the movable plate 41 is rotated and merged into the notch 3. The tyre 5 can pass through the connecting kit 2 and be taken off from the outer side of the rotary kiln 1 for maintenance, repair or replacement and other operations.

[0028] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprises / include" or "has" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
