[0002] Polyaluminum chloride is made by mixing materials such as bauxite, calcium aluminate powder, and hydrochloric acid. When processing polyaluminum chloride, it is necessary to use aluminum chips or aluminum slag to react with hydrochloric acid. During the reaction process, aluminum chips or aluminum slag, hydrochloric acid, and a catalyst need to be added to the reaction kettle. In the existing polyaluminum chloride processing method, in the initial stage of processing, most of them directly put aluminum chips or aluminum slag, hydrochloric acid, and a catalyst into the reaction kettle together. However, in the actual reaction process, sometimes it is necessary to continuously add aluminum chips or aluminum slag to the reaction kettle according to the actual reaction situation. However, it is very difficult for the existing reaction kettle to continuously feed materials, thus reducing the practicability of the reaction kettle during use. At the same time, most of the existing stirring devices of the reaction kettle can only stir the mixed raw materials circumferentially, and the stirring method is relatively single, which is inconvenient to fully mix the raw materials, thus reducing the reaction rate of polyaluminum chloride.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0020] Please refer to Figures 1-5 , the present invention provides a polyaluminum chloride reaction kettle, including a reaction kettle body 1, a discharge pipe 2 is fixed on the outer surface of the reaction kettle body 1, a mixing chamber 3 and a storage chamber 4 are opened on the inner and outer sides of the reaction kettle body 1, an inner sealing cover 5 is fixed to the port of the mixing chamber 3 by bolts, an inner feed pipe 6 is fixed on the inner sealing cover 5, an outer sealing cover 7 is fixed to the port of the storage chamber 4 by bolts, an outer feed pipe 8 slides on the outer sealing cover 7, a feed chute 9 is opened between the mixing chamber 3 and the storage chamber 4, an electric rod 10 is installed on the inner bottom surface of the storage chamber 4, a pushing plate 11 is fixed to the top of the electric rod 10, and an inclined surface 12 is opened on the pushing plate 11;
[0021] Inside the storage cavity 4 and above the pushing plate 11, there is a sliding type sealing plate 13. A spring 14 is movably sleeved on the outer feeding pipe 8. Inside the reaction kettle body 1, a lower motor 15 is fixed. The output end of the lower motor 15 is fixed with a driving cylinder 16. On the inner top surface of the inner sealing cover 5, an upper motor 17 is fixed. The output end of the upper motor 17 is fixed with a driving rod 18. On the driving cylinder 16, a hollow stirring cylinder 19 is fixed. On the surface of the hollow stirring cylinder 19, two groups of rotating grooves 20 are opened. Inside the inner and outer two groups of rotating grooves 20, an inner rotating ring 21 and an outer rotating ring 22 rotate. On the surface of the inner rotating ring 21, an inner stirring frame 23 is fixed. On the surface of the outer rotating ring 22, an outer stirring frame 24 is fixed. On the surface of the outer feeding pipe 8 and inside the driving cylinder 16, a driving bevel gear 25 is fixed. Inside the hollow stirring cylinder 19, a horizontal rotating shaft 26 rotates. On the end face of the horizontal rotating shaft 26 and inside the driving cylinder 16, a driven bevel gear 27 is fixed. On the surface of the horizontal rotating shaft 26 and inside the hollow stirring cylinder 19, a first driving toothed ring 28 and a second driving toothed ring 29 are fixed. Inside the hollow stirring cylinder 19, a fixed shaft 30 is fixed. On the end face of the fixed shaft 30, a driven toothed ring 31 rotates. On the inner side surfaces of the inner rotating ring 21 and the outer rotating ring 22, an inner toothed ring 32 is fixed. Pour the raw materials required for the reaction of aluminum chips or aluminum slag, hydrochloric acid, and the catalyst into the storage cavities 4 at different positions. Therefore, multiple raw materials can be stored simultaneously. When it is necessary to add materials into the mixing cavity 3, starting the electric rod 10 can drive the pushing plate 11 to move upward. Thus, the pushing plate 11 can push the materials above it upward. Therefore, through the pushing plate 11, the materials inside the storage cavity 4 can be pushed into the mixing cavity 3. Therefore, the mixing cavity 3 can be fed with materials.
[0022] Further, the driving rod 18 extends into the driving cylinder 16 and is rotatably connected to the driving cylinder 16. The driving bevel gear 25 meshes with the driven bevel gear 27. When the upper motor 17 drives the driving bevel gear 25 to rotate through the driving rod 18, the driving bevel gear 25 can drive the horizontal rotating shaft 26 to rotate by meshing with the driven bevel gear 27, so that the horizontal rotating shaft 26 can drive the inner stirring frame 23 and the outer stirring frame 24 to rotate subsequently.
[0023] Further, the first driving toothed ring 28 meshes with the driven toothed ring 31. The driven toothed ring 31 meshes with the inner toothed ring 32 on one side of the outer rotating ring 22, and the first driving toothed ring 28 does not mesh with the inner toothed ring 32. The second driving toothed ring 29 meshes with the inner toothed ring 32 on one side of the inner rotating ring 21. When the first driving toothed ring 28 and the second driving toothed ring 29 rotate in the same direction, and the second driving toothed ring 29 can drive the inner stirring frame 23 to rotate in the same direction through the inner toothed ring 32 and the inner rotating ring 21, and the first driving toothed ring 28 can make the driven toothed ring 31 drive the outer stirring frame 24 to rotate in the other direction through the inner toothed ring 32 and the outer rotating ring 22 by meshing with the driven toothed ring 31, that is, the inner stirring frame 23 and the outer stirring frame 24 can rotate in opposite directions, so that the materials can be evenly stirred and mixed through the inner stirring frame 23 and the outer stirring frame 24.
[0024] Furthermore, the inner rotating ring 21, the inner stirring frame 23 and the inner gear ring 32 are fixed to each other, and the outer rotating ring 22, the outer stirring frame 24 and the inner gear ring 32 are fixed to each other. The inner rotating ring 21 and the outer rotating ring 22 divide the hollow stirring cylinder 19 into multiple segments, and the inner rotating ring 21 and the outer rotating ring 22 are rotationally connected to the hollow stirring cylinder 19 at both ends in the circumferential direction. When the two groups of inner gear rings 32 inside and outside rotate, the inner stirring frame 23 can be driven to rotate by the inner rotating ring 21, and the outer stirring frame 24 can be driven to rotate by the outer rotating ring 22, so that the inner stirring frame 23 and the outer stirring frame 24 can stir the material when they rotate.
[0025] Furthermore, the inner stirring frame 23 and the outer stirring frame 24 are U-shaped frames. The inner stirring frame 23 is located inside the outer stirring frame 24, and the inner stirring frame 23 and the outer stirring frame 24 do not contact each other, which is convenient for the inner stirring frame 23 and the outer stirring frame 24 to rotate, so as to turn and stir the mixed material in the mixing chamber 3 in the up and down directions, so as to uniformly stir and mix the material in the mixing chamber 3.
[0026] Furthermore, the bottom end of the outer feed pipe 8 is fixedly connected to the U-shaped sealing plate 13. The upper and lower ends of the spring 14 are in contact with the U-shaped sealing plate 13 and the inner top surface of the storage chamber 4. When the electric rod 10 drives the push plate 11 to move upward, at this time, the push plate 11 can push the U-shaped sealing plate 13 to move upward and make the spring 14 contract. Therefore, when the U-shaped sealing plate 13 moves upward, the feed slot 9 can be opened, so that the material stacked on the push plate 11 can be poured into the mixing chamber 3 through the feed slot 9.
[0027] In use, aluminum chips or aluminum slag, hydrochloric acid, and raw materials required for the reaction with the catalyst are poured into the storage chambers 4 at different positions. Therefore, multiple raw materials can be stored simultaneously. When it is necessary to add materials into the mixing chamber 3, starting the electric rod 10 can drive the pushing plate 11 to move upward. Thus, the pushing plate 11 can push the materials above it upward. And when the pushing plate 11 contacts the U-shaped sealing plate 13, it can also drive the U-shaped sealing plate 13 to move upward. Therefore, when the U-shaped sealing plate 13 moves upward, the feeding groove 9 can be opened. And as the pushing plate 11 continues to move upward, the materials above it can be poured into the mixing chamber 3 through the feeding groove 9. Then, the U-shaped sealing plate 13 is moved downward to close the feeding groove 9. Thus, the mixing chamber 3 can be sealed. In this way, the cycle continues, and materials can be continuously added into the mixing chamber 3. In addition, starting the lower motor 15 enables it to drive the hollow stirring cylinder 19 to rotate in the circumferential direction through the driving cylinder 16. Therefore, the materials can be stirred in the circumferential direction through the hollow stirring cylinder 19. At the same time, starting the upper motor 17 enables it to drive the driving bevel gear 25 to rotate through the driving rod 18. Furthermore, through the meshing of the driving bevel gear 25 with the driven bevel gear 27, the transverse rotating shaft 26 can drive the first driving gear ring 28 and the second driving gear ring 29 to rotate. The second driving gear ring 29 meshes with the internal gear ring 32 at this place, enabling the internal gear ring 32 to drive the internal stirring frame 23 to rotate to one side through the internal rotating ring 21. The first driving gear ring 28 meshes with the driven gear ring 31, enabling the driven gear ring 31 to rotate in the opposite direction. Therefore, the driven gear ring 31 drives the external stirring frame 24 to rotate in the opposite direction through the internal gear ring 32 and the external rotating ring 22 at this place. That is, the internal stirring frame 23 and the external stirring frame 24 can rotate in the opposite direction, so as to turn and stir the materials inside the mixing chamber 3 in the vertical direction through the internal stirring frame 23 and the external stirring frame 24, so as to make the materials evenly and fully mixed, thereby improving the reaction rate of aluminum chloride synthesis.
[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
