Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of oxygen-enriched bottom-blown smelting furnaces, specifically an oxygen-enriched bottom-blown smelting furnace for antimony recovery. Background Technology
[0002] In the field of non-ferrous metal recycling, oxygen-enriched bottom-blown smelting technology has become an important process for recovering metals such as antimony due to its high efficiency and energy saving characteristics. As the core equipment of this process, the structure of the oxygen-enriched bottom-blown smelting furnace and the performance of its furnace bottom cylinder and cooling device directly affect the equipment's service life, production efficiency, and safety.
[0003] Currently, the hearth and furnace body of traditional oxygen-enriched bottom-blown smelting furnaces are typically integrated. Under the long-term high-temperature, highly corrosive smelting environment, the hearth is highly susceptible to erosion from the high-temperature antimony melt and complex chemical reactions, leading to wear, thinning, and even perforation. Once the hearth is damaged, the entire furnace body often needs to be disassembled and repaired, a cumbersome, time-consuming, and labor-intensive process that results in prolonged equipment downtime, severely impacting production progress and corporate economic benefits. Furthermore, the integrated structure makes precise repair of localized damage to the hearth and furnace body difficult, increasing maintenance costs and complexity. Regarding cooling devices, existing water jacket cooling methods suffer from limited cooling efficiency and inconvenient maintenance. Conventional water jackets often employ a metal sleeve structure tightly attached to the furnace body surface. While they can remove some heat through circulating water, the cooling effect is still unsatisfactory for critical high-temperature components like the hearth. Moreover, the internal flow channels of the water jacket are prone to scaling and blockage, leading to decreased cooling efficiency. Repairing the water jacket requires interrupting the entire cooling system, further impacting production continuity.
[0004] Therefore, this utility model provides an oxygen-enriched bottom-blown smelting furnace for antimony recovery. Utility Model Content

Several sets of L-shaped frames are provided, and the sets of L-shaped frames are fixedly mounted in a ring on the inner wall of the toothed ring.

[0024] like Figures 1 to 4As shown in the embodiment of this utility model, an oxygen-enriched bottom-blown smelting furnace for antimony recovery includes a furnace body 1; a docking mechanism 2 and a connecting mechanism 3 are provided at the bottom of the furnace body 1; a water storage mechanism 4 is provided at the bottom of the furnace bottom cylinder 33, and a driving mechanism 5 is provided on one side of the water storage mechanism 4; an agitation mechanism 6 is provided at the top of the water storage mechanism 4, and a heat dissipation component 7 is provided on the surface of the water storage mechanism 4; the docking mechanism 2 includes a slot 21, a ring 22, and a rectangular block 23, with the slot 21 being formed inside the furnace body 1. At the bottom of the wall, the surface of the insert ring 22 is fixedly installed with the rectangular block 23. The insert ring 22 and the rectangular block 23 are movably inserted into the bottom of the inner wall of the smelting furnace body 1 through the opening of the slot 21. The connecting mechanism 3 includes a connecting ring 31, fixing bolts 32 and a furnace bottom cylinder 33. The connecting ring 31 is fixedly installed at the bottom of the insert ring 22, and the bottom of the connecting ring 31 is fixedly installed with the furnace bottom cylinder 33. Several sets of fixing bolts 32 are provided. The connecting ring 31 is threadedly installed with the smelting furnace body 1 through the setting of several sets of fixing bolts 32. The water storage mechanism 4 includes a support rod. 41. A water storage tank 42 and a support leg 43. A support rod 41 is fixedly installed at the bottom of the furnace bottom cylinder 33. The bottom of the support rod 41 is fixedly installed with the water storage tank 42. The bottom surface of the water storage tank 42 is fixedly installed with the support leg 43. The drive mechanism 5 includes a shaft frame 51, a gear 52, a motor 53, and a belt 54. The shaft frame 51 is fixedly installed on one side of the support leg 43. The inner wall of the top of the shaft frame 51 is rotatably installed with the gear 52. The side of the support leg 43 near the shaft frame 51 is fixedly installed with the motor 53. The output end of the motor 53 is connected to the belt 54. Connected to gear 52, the stirring mechanism 6 includes a gear ring 61, an L-shaped frame 62, and an inclined plate 63. The gear ring 61 is rotatably mounted on the top of the water storage tank 42. Several sets of L-shaped frames 62 are provided, and the several sets of L-shaped frames 62 are fixedly mounted in a ring on the inner wall of the gear ring 61. The side of the L-shaped frame 62 away from the gear ring 61 is fixedly mounted to the inclined plate 63. The heat dissipation assembly 7 includes a first heat dissipation back fin 71 and a second heat dissipation back fin 72. The first heat dissipation back fin 71 is fixedly mounted on the surface of the water storage tank 42, and the second heat dissipation back fin 72 is fixedly mounted on the surface of the furnace bottom cylinder 33.
[0025] like Figures 1 to 4As shown, the slot 21 allows the insertion ring 22 and rectangular block 23 to quickly align with the furnace body 1. The cooperation of the insertion ring 22 and rectangular block 23 facilitates the alignment and calibration of the furnace body 1, ensuring that the screw holes of the furnace body 1 match the connecting ring 31 without further correction. The cooperation of the connecting ring 31, fixing bolt 32, and furnace bottom cylinder 33 enables the detachable connection between the cylinder bottom and the furnace body 1, facilitating disassembly and maintenance after use and preventing increased wear and tear over long-term use. The support rod 41 provides support for the furnace bottom cylinder 33. The cooperation of the water tank 42 and support leg 43 stores cooling water. Simultaneously, the cooling water exposed to air accelerates cooling, further improving heat dissipation efficiency and reducing the temperature of the furnace bottom cylinder 33. The combined use of the shaft frame 51, gear 52, motor 53, and belt 54 enables the agitator 6 to rotate. Through user control, the agitator 6 can be driven to rotate slowly to prevent excessive speed and potential coolant leakage. The combined use of the gear ring 61, L-shaped frame 62, and inclined plate 63, driven by the drive mechanism 5, rotates and continuously agitates the cooling water inside the water tank 42. This allows the cooling water near the furnace bottom cylinder 33 to mix with the cooling water on the other side, reducing the overall temperature and achieving uniform heating. The first heat dissipation fin 71 quickly dissipates the heat from the coolant inside the water tank 42 through the air, while the second heat dissipation fin 72 further transfers the heat generated by the furnace bottom cylinder 33 during use to the coolant in the water tank 42, achieving efficient temperature control.
[0026] Working principle: During operation, first place the furnace body 1 on a flat surface, then fill the water tank 42 with cooling water. Next, align the slot 21 at the bottom of the furnace body 1 with the insertion ring 22 and the rectangular block 23, and insert it downwards, ensuring a perfect connection between the connecting ring 31 and the furnace body 1. Then, the user connects the furnace body 1 to the connecting ring 31 using the fixing bolts 32. It is then ready for use. During operation, the furnace bottom cylinder 33 generates heat and transfers it to the second heat dissipation fin 72. Because the second heat dissipation fin 72 is immersed in cooling water, the cooling water quickly exchanges heat with it to cool it down. Due to the slow conduction speed of liquids, [the process is more efficient]. To ensure effective heat dissipation of the furnace bottom cylinder 33, the user needs to start the motor 53 to drive the gear 52 to rotate via the belt 54. The rotation of the gear 52 will drive the gear ring 61 to rotate, and the rotation of the gear ring 61 will drive multiple sets of L-shaped frames 62 and inclined plates 63 to rotate. When the inclined plates 63 rotate, they will stir the cooling water inside the water storage tank 42 through their tilt angle, so that the cooling water can be heated evenly. When the cooling water begins to heat up, it will transfer heat to the first heat dissipation dorsal fin 71 for heat dissipation through heat conduction. After use, the user can separate the smelting furnace body 1 from the furnace bottom cylinder 33 and perform maintenance and upkeep on the smelting furnace body 1 and the furnace bottom cylinder 33 in sequence to ensure that they can be used for a long time.
