[0002] Alumina fiber is a polycrystalline inorganic fiber whose main component is alumina. It usually also contains about 5% silicon dioxide to stabilize the crystal phase and inhibit grain growth at high temperatures. Alumina fiber is one of the newest ultra-lightweight high-temperature insulation materials at home and abroad. It is made by preparing a colloidal solution with a certain viscosity from soluble aluminum and silicon salts. The solution is spun into fiber preforms by high-speed centrifugation. Then, it is transformed into Al-Si alumina polycrystalline fiber through processes such as dehydration, drying and medium-high temperature heat treatment for crystallization. Currently, centrifugal forming equipment is required in the production and processing of alumina fiber.

A cover plate 803 is provided at the bottom of the rotating frame 802. By setting a locking block 6 and a locking groove 7, the bottom of the cylinder 5 can be limited. By setting a cover plate 803, the material can be blocked.

A lifting block 806 is rotatably connected to the top of the cover plate 803 via a bearing. A first screw 807 is rotatably connected to the top of the lifting block 806 via a bearing. The top of the first screw 807 passes through the rotating frame 802 and is fixedly connected to a handwheel 808. Four limiting rods 809 are fixedly connected to the top of the lifting block 806. The top of the limiting rods 809 passes through the top of the rotating frame 802. By setting the connecting rod 805, it can be inserted into the connecting plate 804, which facilitates the fixing of the cover plate 803 and the cylinder 5. By setting the handwheel 808, it is easy for the user to rotate the first screw 807. By setting the limiting rods 809, the movement range of the cover plate 803 and the lifting block 806 can be limited. Reference Figure 3 and Figure 4A limiting shell 810 is fitted on one side of the rotating frame 802. A limiting frame 811 is fixedly connected to one side of the limiting shell 810.

One end of the second screw 13 passes through the inner cavity of the regulating box 9 and is threadedly connected to a screw sleeve 14. A lifting frame 15 is fixedly connected to the front and rear sides of one side of the screw sleeve 14. One end of the lifting frame 15 passes through the regulating box 9 and is fixedly connected to the fan 11. A protective frame 16 is fitted on the surface of the cylinder 5. The bottom of the protective frame 16 is fixedly connected to the support frame 2. By setting the second motor 12, it can be used to drive the second screw 13 to rotate. By setting the lifting frame 15, it is easy to connect the screw sleeve 14 to the fan 11. By setting the protective frame 16, it can play a protective role and prevent the cylinder 5 from being thrown out.

[0019] Working principle: When disassembling the cylinder 5, first turn the handwheel 808 to drive the first screw 807 to rotate. The rotation of the first screw 807, through the cooperation of the lifting block 806, drives the cover plate 803 and the connecting rod 805 to move upward, so that the connecting rod 805 separates from the connecting plate 804. Then, pull the pull rod 815, which, through the cooperation of the pull plate 813, drives the insert block 816 to move upward and remove it from the slot 817, releasing the restriction on the rotating frame 802. At this time, the rotating frame 802 can be rotated, and the rotating frame 802 drives the cover plate 803 to be removed from the cylinder 5. Then, the cylinder 5 can be moved upward for disassembly. When it is necessary to centrifuge the material inside the cylinder 5, put the cylinder 5 into the protective frame 16 and let the locking block 6 lock into the locking slot 7. Then, rotate the rotating frame 802 to move the cover plate 803 above the cylinder 5 until one end of the rotating frame 802 rotates into the limiting shell 810, through the spring 814 and The pull plate 813 engages to move the insert block 816 downwards into the slot 817, which fixes the rotating frame 802. Then, the handwheel 808 reverses the first screw 807. The reversal of the first screw 807 causes the lifting block 806 and the cover plate 803 to move downwards. The cover plate 803 contacts the cylinder 5 to seal it. The cover plate 803 drives the connecting rod 805 to insert into the connecting plate 804, thus completing the connection between the cover plate 803 and the cylinder 5. Controlling the first motor 3 can drive the cylinder 5 to rotate and centrifuge the material. During centrifugation, heat is generated. Controlling the fan 11 to turn on can blow air onto the surface of the cylinder 5, accelerating the cooling speed of the cylinder 5. Controlling the second motor 12 can drive the second screw 13 to rotate. The second screw 13, through the engagement of the screw sleeve 14 and the lifting frame 15, can drive the fan 11 to adjust the operating height, increase the air blowing range, and further accelerate the cooling speed of the cylinder 5.
