A discharge pipe 10 is connected to the bottom surface of the alumina fiber preparation tank 1. The spiral blade 4 is placed in the discharge pipe 10 and rotates to push the raw materials during the discharge process to prevent the raw materials from clogging the discharge pipe 10. The inner wall of the discharge pipe 10 and the alumina fiber preparation tank 1 are provided with an anti-stick coating, which is a polytetrafluoroethylene coating, which can effectively prevent the raw materials from sticking to the pipe wall during the discharge process, thereby ensuring the smoothness of the mixed discharge.

[0038] It should be noted that the bow-shaped stirring rod 9, the stirring shaft 5 and the hook-shaped stirring rod 6 are arranged in an interlaced manner, and there will be no motion interference during the rotation and stirring process.

[0039] It should be noted that the alumina fiber preparation tank 1 is a sealed cylindrical container with a feed port on its side wall. The feed port is used to add alumina raw materials and related additives into the preparation tank. Since setting up the feed port for feeding belongs to the existing technology, it will not be described in detail.

[0040] An observation window is provided on the surface of the alumina fiber preparation tank 1. The observation window is made of a transparent high-temperature resistant material, which is convenient for the operator to observe the stirring condition of the raw materials in the tank in real time.

[0041] A device for preparing aluminum oxide fiber also includes a first driving member, a second driving member and a rotating member.

[0042] The first driving member is used to drive the rotating column 2 to rotate. The first driving member includes a first motor 21, a transmission shaft 22, a first pulley 23, a second pulley 24 and a belt 25. The first motor 21 is fixed on the top surface of the alumina fiber preparation tank 1, the transmission shaft 22 is fixed on the output end of the first motor 21, the first pulley 23 is fixed on the transmission shaft 22, the second pulley 24 is fixedly sleeved on the rotating column 2, and the belt 25 is wound around the first pulley 23 and the second pulley 24.

[0043] The second drive member is used to drive the rotation of the rotating shaft 3. The second drive member includes a frame 31 and a second motor 32. The frame 31 is fixed to the top surface of the alumina fiber preparation tank 1. The second motor 32 is fixed to the top surface of the frame 31. The output end of the second motor 32 is fixedly connected to the rotating shaft 3. Driven by the second motor 32, the rotating shaft 3 can rotate independently of the rotating column 2, driving the spiral blades 4 to rotate within the rotating column 2 and the discharge pipe 10, achieving vertical stirring of the raw materials and promoting the discharge of the raw materials.

[0044] The rotating part is used to drive multiple rotating rods 8 to rotate synchronously. The rotating part includes a support 81, a large gear 82 and a small gear 83. The support 81 is fixed on the top wall of the alumina fiber preparation tank 1, the large gear 82 is fixed on the support 81, and the small gear 83 is fixed on the rotating rod 8. There are multiple small gears 83 corresponding to the rotating rod 8. The multiple small gears 83 are all at the same horizontal plane as the large gear 82, and the multiple small gears 83 are all engaged with the large gear 82. The bow-shaped stirring rods 9 are arranged corresponding to the number of rotating rods 8, so that the rotating rod 8 and the bow-shaped stirring rods 9 rotate and stir around their respective axes, further enhancing the stirring effect on the raw materials in different areas of the preparation tank.

[0045] It should be noted that a discharge valve is installed in the discharge pipe 10, which is in a closed state when there is no need for discharge and is opened only when discharge is required. This belongs to the existing technology and will not be described in detail.

[0046] The functional principle of this utility model can be explained through the following operation modes:

[0047] First, the operator needs to slowly pour the alumina fiber raw material to be processed into the alumina fiber preparation tank 1 through the feed port.

[0048] Then the first motor 21 is started to drive the transmission shaft 22 to rotate, and the first pulley 23 fixed on the transmission shaft 22 also rotates synchronously. With the help of the transmission action of the belt 25, the rotation of the first pulley 23 will drive the second pulley 24 matched with it to rotate, and the rotating column 2 located between the two pulleys will start to rotate in the alumina fiber preparation tank 1.

[0049] During the continuous rotation of the rotating column 2, the turntable 7 fixedly sleeved on the outside of the rotating column 2 will also rotate together. At this time, the small gear 83 on the rotating rod 8 set in the turntable 7 will come into contact with the large gear 82 fixed on the support 81 and engage with each other. Since the large gear 82 is in a stationary state, as the turntable 7 rotates, the small gear 83 will be forced to start rotating under the meshing action, thereby driving the rotating rod 8 to rotate around its own axis in the turntable 7, and the bow-shaped stirring rod 9 fixed at the bottom of the rotating rod 8 will also rotate synchronously, thereby carrying out sufficient mixing and stirring operations on the raw materials in the alumina fiber preparation tank 1.

[0050] At the same time, as the rotating column 2 rotates, the hook-shaped stirring rod 6 and the stirring shaft 5 fixed to its outer wall will also fully contact and act with the alumina fiber raw material, so that the raw material can achieve a more sufficient and uniform mixing and stirring effect in the tank.

[0051] After the raw materials have undergone the above-mentioned stirring and mixing operations and have met the various pre-set requirements, the second motor 32 is then started to drive the rotating shaft 3 connected thereto to rotate, thereby driving the spiral blade 4 fixed to the bottom surface of the rotating shaft 3 to rotate together, and the stirred and mixed raw materials will begin to be discharged through the discharge pipe 10 connected to the discharge port at the bottom of the alumina fiber preparation tank 1. In addition, during the raw material discharge process, the spiral blade 4 located in the discharge pipe 10 will continuously rotate. With the driving force generated by its rotation, it can effectively ensure the continuity of the discharge process, and at the same time, it can effectively prevent the raw materials from clogging the discharge pipe 10 during the discharge process, ensuring the smooth progress of the entire discharge process.

[0052] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
