Description

Technical Field

[0001] This utility model relates to the field of white fused alumina smelting technology, specifically to a high-efficiency and energy-saving white fused alumina smelting device. Background Technology

[0002] White fused alumina is a new type of acid- and alkali-resistant, wear-resistant material produced from high-quality alumina through multiple processes such as smelting and processing. The name white fused alumina comes from its white appearance and hardness. Corundum is the second hardest mineral on Earth, second only to diamond. It is widely used in the wear-resistant industry, especially in some heavy industrial fields. In the production process of white fused alumina, smelting equipment is indispensable. By pouring the white fused alumina raw material into the smelting furnace and heating it, a high-temperature reaction occurs between the raw materials, and finally, white fused alumina is smelted.

[0003] The existing patent document CN222578862U discloses a white fused alumina smelting equipment, and the protected claim "includes support plates and a discharge mechanism; support plates: there are two, distributed left and right, a base is provided between the lower ends of the two support plates, a smelting furnace body is rotatably connected between the two support plates through a rotating shaft, a crucible is provided inside the smelting furnace body, refractory bricks are provided between the upper end of the outer arc surface of the crucible and the upper end of the inner arc surface of the smelting furnace body, an induction coil is provided in the middle between the outer arc surface of the crucible and the inner arc surface of the smelting furnace body, a high-frequency current generator is provided on the surface of the left support plate, a microcontroller is provided on the surface of the right support plate, and the input terminal of the microcontroller is electrically connected to an external power supply. This white fused alumina smelting equipment reduces the influence of liquid level changes on discharge control, accurately controls the discharge speed of the white fused alumina smelting equipment, makes the discharge speed of the white fused alumina smelting equipment more stable, facilitates the control of the white fused alumina smelting equipment for quantitative discharge, and makes the use of the white fused alumina smelting equipment more convenient."

[0004] However, the white fused alumina smelting equipment in the aforementioned publicly available literature mainly focuses on reducing the impact of liquid level changes on discharge control, accurately controlling the discharge speed of the white fused alumina smelting equipment, making the discharge speed of the white fused alumina smelting equipment more stable, facilitating quantitative control of the white fused alumina smelting equipment, and making the use of the white fused alumina smelting equipment more convenient. However, it does not take into account that during the smelting process, a large amount of high-temperature flue gas directly escapes from the furnace body discharge port, which is one of the main ways to cause heat loss, seriously reducing energy utilization efficiency and leading to serious energy waste.

[0017] Please see Figure 1-4 A high-efficiency and energy-saving white corundum smelting device includes a base 1 and a furnace body 2. The furnace body 2 is tilted on the base 1. The furnace body 2 is provided with a swingable and openable feed top cover 3 and a discharge pipe 4 provided on the side of the furnace body 2. The furnace body 2 is provided with a recovery mechanism for recovering the high-temperature flue gas at the discharge pipe 4. The recovery mechanism includes a pipe body 5 that can be sleeved and connected with the discharge pipe 4 and a pipeline 6 for conveying the high-temperature flue gas. The base 1 serves as the basic support platform for the entire device, providing a stable installation and operating environment for the furnace body 2. The furnace body 2 is the core reaction vessel for white corundum smelting, where all smelting processes take place. It is tiltable to facilitate the pouring out of the molten material after smelting. The feed top cover 3 can swing open and close to add the raw materials required for smelting into the furnace body 2. The discharge pipe 4 is the discharge channel for smelting products (such as slag or partial molten material) and is also the main location for high-temperature flue gas leakage.

[0018] Please see Figure 1 and Figure 2 One end of the pipe body 5 is provided with a retractable pipe 6 with high temperature resistance, and the outside of the discharge pipe 4 is provided with a docking ring 17. The docking end of the pipe body 5 is provided with a docking ring 2 18 that cooperates with the docking ring 17. Pipe 5 serves as the inlet and primary channel for flue gas recovery. One end of it can be tightly connected to the discharge pipe 4 of furnace 2, and the other end is connected to the telescopic pipe 6. The telescopic pipe 6 is a flexible connection section for flue gas transportation. When furnace 2 is tilted or the recovery mechanism is adjusted, the position and angle between pipe 5 and the fixed subsequent pipe will change. The telescopic pipe 6 can adapt to these changes to ensure that the flue gas transportation channel is always unobstructed and sealed. When pipe 5 is precisely connected to discharge pipe 4, docking ring 2 18 will fit tightly with docking ring 1 17 to form a reliable high-temperature seal and prevent flue gas leakage.

[0019] Please see Figure 3 and Figure 4 The top of the furnace body 2 is provided with a concave frame 7. Inside the concave frame 7, two sets of support frames 8 are movable and adjustable. The support frames 8 are provided with electric telescopic rods 9. The output end of the electric telescopic rods 9 is provided with a connector 10, and one end of the connector 10 is fixedly connected to the outside of the tube body 5. Inside the concave frame 7, multiple sets of lead screws 11 are rotatably provided. Lead screw nuts 12 are meshed on lead screws 11. Multiple sets of connecting frames 13 are provided on lead screw nuts 12, and one end of the connecting frame 13 is fixedly connected to the outside of the support frame 8. Gear 14 is fixedly provided on the outside of lead screw 11. Multiple sets of drive motors 15 are fixedly provided inside the concave frame 7. The output end of the drive motor 15 is fixedly provided with a gear 2 16 that meshes with gear 14. The concave frame 7 serves as the mounting base for the entire adjustment mechanism, fixed to the top of the furnace body 2, providing stable support and a running track. The drive motor 15 is the power source for the lifting and moving of the tube body 5. Gear 14 and gear 2 16 are the power transmission devices for the motor, transmitting the rotational motion of the motor to the lead screw 11. The lead screw 11 and lead screw nut 12 are used to convert the rotational motion of the motor into the linear lifting and lowering motion of the lead screw nut 12. The connecting frame 13 transmits the motion of the lead screw nut 12 to the support frame 8, causing it to lift and lower within the concave frame 7. The support frame 8 carries and drives the entire tube body 5 adjustment mechanism to lift and lower. The electric telescopic rod 9 is used to drive the tube body 5 to adjust its position forward and backward, allowing the tube body 5 to move away from or closer to the discharge pipe 4. The connecting piece 10 serves to connect the electric telescopic rod 9 and the tube body 5.

[0020] Working principle: As the smelting process proceeds, the electric telescopic rod 9 on the support frame 8 is activated first, driving the tube 5 to smoothly move out of the groove outside the concave frame 7, leaving the initial storage state and reserving space for subsequent height adjustment and docking operations. Subsequently, the drive motor 15 is activated, and its output gear 16 precisely meshes with the gear 14 outside the lead screw 11, transmitting the motor's rotational power to the lead screw 11. When the lead screw 11 rotates, the lead screw nut 12 meshing with it moves linearly up and down along the lead screw axis, synchronously driving the support frame 8 inside the concave frame 7 to rise and fall through the connecting frame 13, until the support frame 8 moves to a position that perfectly matches the height of the discharge tube 4, completing the process. Before docking, the height is calibrated. Finally, the electric telescopic rod 9 on the support frame 8 is activated again, and the pipe body 5 is finely adjusted back and forth through the connector 10, so that the pipe body 5 gradually moves closer to the discharge pipe 4. When the axis of the pipe body 5 is aligned with that of the discharge pipe 4, the docking ring 18 at the docking end of the pipe body 5 and the docking ring 17 on the outside of the discharge pipe 4 fit tightly together to form a reliable high-temperature sealing structure, which prevents flue gas leakage from the source. After the sealing docking is completed, the high-temperature flue gas generated at the discharge pipe 4 is efficiently collected by the pipe body 5, and then stably transported to the preheater, waste heat boiler and other subsequent waste heat utilization equipment through the high-temperature resistant telescopic pipe 6 connected to one end of the pipe body 5, so as to realize the recovery and reuse of heat.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
