Description

Technical Field

[0001] The utility model relates to the technical field of alumina fiber preparation, in particular to a temperature and humidity control device for alumina fiber preparation. Background Art

[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 the growth of grains at high temperatures. Alumina fiber is one of the latest ultra-light high-temperature insulation materials at home and abroad. It adopts the high-tech "sol-gel" method to make soluble aluminum and silicon salts into a colloidal solution with a certain viscosity. The solution is spun into a fiber embryo by high-speed centrifugation, and then transformed into Al-Si alumina polycrystalline fiber through dehydration, drying and medium-high temperature heat treatment and crystallization. Its main crystal phase is mainly corundum phase and a small amount of mullite phase. The chemical composition is Al2O3 (95%) + SiO2 (5%). The fiber diameter is 3-7um and the single fiber length is 10-150mm. It is white in appearance, smooth, soft and elastic, just like cotton wool. It combines the characteristics of crystal material and fiber material, with an operating temperature of 1450℃-1600℃ and a melting point of 1840℃. It has good heat resistance and stability. Its thermal conductivity is 1 / 6 of that of ordinary refractory bricks, and its bulk density is only 1 / 25 of that, with an energy saving rate of 15-45%.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-6 , the utility model provides a technical solution:

[0027] Example 1: A temperature and humidity control device for preparing alumina fiber: comprising a base 1, a drying chamber 2, a sealing shell 3 and a sealing cover 4, wherein the drying chamber 2 is arranged on the top of the base 1, a support frame 5 is installed on the top of the drying chamber 2, the sealing shell 3 is installed on the outer surface of the drying chamber 2, the sealing cover 4 is installed on the top of the sealing shell 3, a pressure relief valve 41 is provided on the surface of the sealing cover 4, and a humidity sensor module 42 is installed on the top of the sealing cover 4;

[0028] The alumina fiber spiral spraying and receiving unit is arranged in the support frame 5 area, and is used for performing rotary spraying preparation operations during the alumina fiber preparation process.

[0029] The alumina fiber spiral spraying and receiving unit includes a spraying part, which includes a fixed shell 51. The fixed shell 51 is installed on the top of the support frame 5. A liquid phase material tank 52 is installed on the top of the fixed shell 51. The bottom of the liquid phase material tank 52 is vertically connected and connected with an electric rotary joint 527. The rotating end of the electric rotary joint 527 is connected and connected with a feeding pipeline 521. The feeding pipeline 521 is set as a bend pipe. A flexible pipeline 523 is installed at one end of the feeding pipeline 521. A reinforcement sleeve 522 is provided on the surface of one end of the feeding pipeline 521. A guide arm 525 is hingedly installed on the outer surface of the reinforcement sleeve 522. A needle-shaped nozzle 524 is installed at one end of the flexible pipeline 523. A rotating shaft seat 526 is installed at one end of the guide arm 525. The rotating end of the rotating shaft seat 526 is fixed to the outside of the needle-shaped nozzle 524.

[0030] The alumina fiber spiral spraying material receiving unit also includes a material receiving part, which includes a conical bin 6. Two groups of side fixed arms 53 are symmetrically installed on the top of the fixed shell 51, and an electric hinge 54 is installed at one end of the side fixed arm 53. The top of the conical bin 6 is installed on the rotating end of the electric hinge 54. The conical bin 6 is set into two groups, and the two groups of conical bins 6 are movably fitted together. A spiral placement platform 61 is set inside the conical bin 6.

[0031] In this embodiment, the rotating end of the electric hinge 54 drives the conical bin 6 to rotate downward, and the conical bin 6 rotates downward to complete the expansion of the bottom of the two groups of conical bins 6. When the two groups of conical bins 6 are expanded, the spiral placement platform 61 area inside the two groups of conical bins 6 is expanded, and the alumina fiber material placed inside the spiral placement platform 61 will fall on the conical surface of the material rack 7 under the action of gravity.

[0032] An alumina fiber material spray drying unit is installed at the bottom of the drying chamber 2.

[0033] The alumina fiber material spray drying unit includes a drying section, which includes a material rack 7. The material rack 7 is arranged in a cone shape. A heating wind box 8 is arranged inside the material rack 7. Gas nozzles 81 are arranged in a ring on the surface of the heating wind box 8.

[0034] The alumina fiber material spray drying unit also includes an air guide portion, which includes a mounting frame 72, a guide air fan 73 is installed on the top of the mounting frame 72, and exhaust holes 71 are provided on the surface of the material rack 7, and the exhaust holes 71 are arranged in several groups at intervals.

[0035] Air inlet pipes 21 are installed on both sides of the drying chamber 2, and the air inlet pipes 21 are connected to the heating air box 8.

[0036] In this embodiment, external air is sucked in and heated through the heating bellows 8 installed inside the material rack 7, and then the dry gas is evenly sprayed upward through the gas nozzle 81 on the surface of the heating bellows 8. The dry gas enters the spiral placement table 61 area through the exhaust pores 71, thereby airflow drying the material on the surface track of the spiral placement table 61, thereby accelerating the molding effect of the alumina fiber material.

[0037] Working principle: During the use of this device, the alumina fiber raw material to be processed is injected into the liquid phase material tank 52 in advance, and then the alumina fiber raw material is heated to a liquid phase state through the liquid phase material tank 52, and then the liquid phase material is passed into the feeding pipe 521 through the electric rotary joint 527, and injected into the flexible pipe 523 and the needle-shaped nozzle 524 part through the feeding pipe 521, and then the electric rotary joint 527 is driven to rotate, so that the electric rotary joint 527 drives the feeding pipe 521 and the needle-shaped nozzle 524 part to rotate at a uniform speed, and the needle-shaped nozzle 524 sprays along the spiral track laid by the spiral placement table 61, and the material sprayed from the needle-shaped nozzle 524 is evenly sprayed onto the surface track of the spiral placement table 61, so that the material is evenly sprayed and output, ensuring the alumina fiber preparation effect;

[0038] During the spraying process of the needle-shaped nozzle 524, the rotating shaft seat 526 can be used to slowly drive the needle-shaped nozzle 524 to perform rotation control. The controlled needle-shaped nozzle 524 sprays the material evenly onto the surface track of the spiral placement table 61 in a spiral rotation state. When the needle-shaped nozzle 524 finishes spraying, the external air can be sucked in and heated through the heating bellows 8 installed inside the material rack 7. Then, the gas nozzle 81 on the surface of the heating bellows 8 evenly sprays the drying gas upward. The drying gas enters the spiral placement table 61 through the exhaust pores 71, thereby drying the material on the surface track of the spiral placement table 61 through airflow, thereby accelerating the forming effect of the alumina fiber material.

[0039] When the alumina fiber material completes a cycle of airflow drying treatment, the electric hinge 54 can be driven, and the rotating end of the electric hinge 54 drives the conical bin 6 to rotate downward, and the conical bin 6 rotates downward to complete the expansion of the bottom of the two groups of conical bins 6. When the two groups of conical bins 6 are expanded, the spiral placement platform 61 area inside the two groups of conical bins 6 is expanded, and the alumina fiber material placed inside the spiral placement platform 61 will fall on the conical surface of the material rack 7 under the action of gravity. Since the material rack 7 is continuously blown by hot gas, the surface of the material rack 7 will perform contact drying and dehumidification treatment on the alumina fiber material, further improving the molding effect of the alumina fiber material.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
