Description

Technical Field

[0001] This utility model relates to the field of aluminum titanate ceramic production and processing, specifically to a mixing device for aluminum titanate ceramics. Background Technology

[0002] The mixing process is one of the key steps in the preparation of aluminum titanate ceramics. The main raw materials include alumina sources (such as alumina powder and kaolin) and titanium dioxide sources (such as titanium dioxide). To improve the properties of aluminum titanate ceramics, additives such as MgO, Fe2O3, SiO2, ZrO2, and CeO2 are usually added. These additives can form solid solutions with aluminum titanate, stabilizing the crystal structure and improving thermal stability and mechanical properties.

[0003] Most existing methods for mixing aluminum titanate ceramic raw materials involve stirring. However, existing stirring functions are relatively simple. When mixing large quantities of raw materials, stratification is likely to occur, and the upper layer of raw materials does not easily come into contact with the lower layer of raw materials for mixing. This requires a long time and makes it difficult to ensure uniform mixing. Utility Model Content

[0024] 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.

[0025] Please see Figures 1-6 In this embodiment of the present invention, a mixing device for aluminum titanate ceramics includes a mixing bucket 1 and a bucket cover 2. The top of the bucket cover 2 is provided with an installation groove 21, and the bottom center of the bucket cover 2 is rotatably connected to a connector 3 via a bearing. The bottom center of the connector 3 is fixedly connected to a rotating cylinder 4. The rotating cylinder 4 is a cylindrical structure with both ends closed, and the upper outer wall of the rotating cylinder 4 is provided with multiple annular arrays of discharge ports 41. The lower outer wall of the rotating cylinder 4 is fixedly connected to a stirring paddle 5, and the lower outer wall of the rotating cylinder 4 is provided with a feed port 7.

[0026] The inside of the rotating drum 4 is equipped with a screw conveying assembly 9, which is rotatably connected to the rotating drum 4 via bearings. A drive mechanism 8 is provided between the drum cover 2 and the rotating drum 4 to drive the rotating drum 4 to rotate and form a relative rotation with the screw conveying assembly 9, so that the material at the lower position enters the rotating drum 4 through the feed inlet 7, and is conveyed to the higher position by the relative rotation of the rotating drum 4 and the screw conveying assembly 9 and discharged from the discharge outlet 41.

[0027] The screw conveyor assembly 9 includes a rotating rod 901, and a spiral blade 902 is provided on the lower outer wall of the rotating rod 901. The outer diameter of the spiral blade 902 is matched with the inner diameter of the rotating drum 4. A through hole is opened in the middle of the connecting member 3 for the rotating rod 901 to pass through, and the rotating rod 901 and the through hole in the middle of the connecting member 3 are rotatably connected by a bearing.

[0028] The drive mechanism 8 includes a mounting cover 801, which is fixed to the upper opening end of the mounting groove 21 by bolts. A first gear 802 is provided inside the mounting groove 21 and is fixedly connected to the upper outer wall of the connector 3. A motor 803 is mounted on the top of the mounting cover 801, and a second gear 804 is fixedly connected to the output end of the motor 803. The second gear 804 meshes with the first gear 802.

[0029] The bottom center of the mounting cover 801 is provided with a limiting hole 805 to restrict the rotation of the spiral conveying assembly 9. The top end of the spiral conveying assembly 9 is inserted into the limiting hole 805. The limiting hole 805 is a polygonal groove, and the top end of the spiral conveying assembly 9 is a polygonal prism. The outer contour of the spiral conveying assembly 9 matches the inner contour of the limiting hole 805.

[0030] In this embodiment: by setting the driving mechanism 8, the rotating drum 4 can drive the stirring paddle 5 to rotate and stir in the mixing tank 1. At the same time, the rotating drum 4 can also form a relative rotation state with the spiral conveying assembly 9, forcing the material near the lower end of the rotating drum 4 to be conveyed from the lower position to the higher position through the spiral conveying structure, thereby enabling the upper and lower layers of materials in the mixing tank 1 to be fully mixed and improving the mixing efficiency of aluminum titanate ceramic.

[0031] Specifically, the first gear 802 is driven to rotate by the second gear 804 driven by the motor 803. The rotating first gear 802 will drive the connecting part 3 to rotate and the rotating drum 4 to rotate. At this time, the rotating drum 4 can be regarded as a stirring rod, which carries the stirring paddle 5 to mix and stir the aluminum titanate ceramic raw material in the mixing tank 1. Since the spiral conveying assembly 9 and the rotating drum 4 are connected by a bearing, and the spiral conveying assembly 9 is also restricted by the limiting hole 805, the rotating drum 4 and the spiral conveying assembly 9 form a relative rotation state. The aluminum titanate ceramic raw material located at the lower end of the rotating drum 4 can enter the rotating drum 4 from the feed port 7. Then, the spiral conveying structure of the rotating drum 4 and the spiral conveying assembly 9 transports the lower layer of aluminum titanate ceramic raw material to a higher position. Finally, it flows out from the discharge port 41 and is scattered on the upper surface of the upper layer of aluminum titanate ceramic raw material. In addition, the mixing efficiency of the aluminum titanate ceramic raw material can be effectively improved by the stirring of the stirring paddle 5.

[0032] It should be noted that the connector 3 in this solution consists of upper and lower parts. The upper part of the connector 3 is a cylindrical structure, and the lower part of the connector 3 is an annular structure. The central holes and grooves of the upper and lower parts of the connector 3 are coaxially arranged.

[0033] Please refer to this carefully. Figures 1-6 The outer wall of the rotating drum 4 is also fixedly connected to a guide plate 6, which is located between the discharge port 41 and the stirring paddle 5. The guide plate 6 is a conical structure with a hollow center.

[0034] In this embodiment: when the lower layer of aluminum titanate ceramic raw material is conveyed to a high position and finally flows out from the discharge port 41, the lower layer of aluminum titanate ceramic raw material falls onto the guide plate 6. It is then evenly scattered on the upper surface of the upper layer of aluminum titanate ceramic raw material away from the outer side of the rotating drum 4 via the guide plate 6, which helps to expand the scattering range and further improve the mixing efficiency of the aluminum titanate ceramic raw material.

[0035] Please refer to this carefully. Figures 1-6 A guide block 71 is provided at one end of the feed inlet 7, and the guide block 71 is set at an angle to the feed inlet 7.

[0036] In this embodiment: by utilizing the angle between the guide block 71 and the feed inlet 7, it is easy to guide the lower layer of aluminum titanate ceramic raw material from the feed inlet 7 into the rotating drum 4, ensuring that the lower layer of aluminum titanate ceramic raw material is conveyed by the screw.

[0037] It should be noted that, in this scheme, the total amount of aluminum titanate ceramic raw material mixed inside the mixing tank 1 should not exceed the lower end of the guide plate 6.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
