Description

Technical Field

[0001] This utility model relates to the field of aluminum ore smelting technology, specifically to a kiln structure for aluminum ore smelting. Background Technology

[0002] Aluminum ore smelting mainly involves extracting aluminum from bauxite, a process that is quite complex. Aluminum is the most important light metal with a wide range of applications. In industrial production, aluminum is mostly produced using the molten salt electrolysis method, with alumina as the raw material, extracted from various aluminum-containing ores. Bauxite is the main raw material for aluminum smelting.

[0003] A search revealed that the announcement number is CN217083342U, and the name is a kiln for metal smelting, including a kiln body, a cover door, and an exhaust box. Research and analysis showed that the equipment utilizes the heat preservation properties of the fireproof brick lifting device, allowing heat to circulate and remain on the corresponding sides of the outer and inner bricks, maximizing heat retention. Materials are picked up and put down using a pallet. The fireproof brick has a double-layer integrated structure, with an alloy plate on the outer side. However, it also has the following drawbacks to some extent.

[0004] For example, the equipment cannot automatically process ore during use, requiring manual feeding by staff. This not only increases the workload of staff but also reduces the processing speed of the ore. Furthermore, it lacks the function of processing the heat in the flue gas. If the flue gas is directly discharged, it will carry a large amount of heat into the air, which can easily affect the surrounding environment. To solve the above technical problems, we have designed a kiln structure for aluminum ore smelting. Utility Model Content

It solves the problems of not being able to automatically feed ore, requiring manual feeding by staff during use, and not having the function of treating the heat in the flue gas, resulting in a large amount of heat being emitted into the air when the flue gas is discharged.

A filling frame is movably installed in the inner cavity of the filter box, and the inner cavity of the filling frame is filled with adsorbent filler. Connecting pipes are connected to the upper and lower sides of the filter box.

[0008] Preferably, the cooling box is connected to a water inlet valve and a water outlet valve on its right side, and the kiln body is fixedly connected to reinforcing legs on both sides.

[0021] Please see Figure 3 A filter box 13 is fixedly connected to the inner cavity of the cooling box 12. Temperature guide plates 14 are installed through both sides of the filter box 13. A filling frame 15 is movably installed in the inner cavity of the filter box 13. The inner cavity of the filling frame 15 is filled with adsorbent filler 16. Connecting pipes 17 are connected to the upper and lower sides of the filter box 13. The top end of the connecting pipe 17 is connected to the kiln body 1. The bottom of the filter box 13 extends to the outside of the cooling box 12. By setting the temperature guide plates 14, it is easy to introduce the heat in the flue gas into the cooling box 12. By setting the connecting pipes 17, it is easy to introduce the flue gas into the filter box 13 or to discharge the flue gas.

[0022] Please see Figure 3 The cooling box 12 is connected to a water inlet valve and a drain valve on the right side. Both sides of the kiln body 1 are fixedly connected to reinforced support legs. The water inlet valve and the drain valve facilitate the replacement of the water in the cooling box 12.

[0023] Please see Figure 1 and Figure 2 The top of both the placement plate 8 and the material feeding support plate 9 are fixedly connected with placement protrusions, and the bottom of the material feeding support plate 9 is fixedly connected with support legs.

[0024] Please see Figure 1 and Figure 2 Guide grooves are provided on both sides of the kiln door panel 7. The right side of the material feeding support plate 9 extends into the inner cavity of the guide groove. By setting the guide groove, it can cooperate with the material feeding support plate 9 to guide and limit the kiln door panel 7, thereby increasing the stability of the kiln door panel 7 when it moves.

[0025] Please see Figure 1 and Figure 4The inner cavity of the support frame 18 is fixedly connected to a first hydraulic cylinder 19. There are several first hydraulic cylinders 19 and support frames 18. The output end of the first hydraulic cylinder 19 is fixedly connected to a connecting support plate 20. The top of the connecting support plate 20 is fixedly installed with a second hydraulic cylinder 21. The output end of the second hydraulic cylinder 21 is fixedly connected to a movable plate 22. The right side of the movable plate 22 is fixedly connected to a lifting rod 23.

[0026] Please see Figure 1 and Figure 4 The bottom of the movable plate 22 is provided with a groove, and a reinforcing rod is fixedly connected to the left side of the connecting support plate 20. The left side of the reinforcing rod is fixedly connected to the second hydraulic cylinder 21. By setting the groove, it is easy for the movable plate 22 to drive the lifting rod 23 to move to the bottom of the container. By setting the reinforcing rod, the stability of the connection between the second hydraulic cylinder 21 and the connecting support plate 20 can be increased.

[0027] In operation, the user first places the container containing aluminum ore onto the placement tray 8, then controls the equipment via an external controller. The user then operates the drive motor 4, causing its output to move the connecting screw plate 6 via the threaded rod 5. The connecting screw plate 6 then moves the placement tray 8 via the kiln door plate 7, pushing the material into the kiln body 1. The user then starts the heater 2 to smelt the aluminum ore. During smelting, the flue gas inside the equipment enters the filter box 13 through the connecting pipe 17. When the flue gas enters the filter box 13, the water in the cooling box 12 absorbs heat from the flue gas. Simultaneously, the heat-conducting plate 14 accelerates the efficiency of flue gas heat conduction, thus speeding up the water's heat absorption. Furthermore, during the heat absorption of the flue gas, the adsorption filling in the filling frame 15... Material 16 also adsorbs harmful substances in the flue gas to prevent them from drifting into the air. After the ore smelting is completed, the user restarts the equipment and then operates the second hydraulic cylinder 21 and the first hydraulic cylinder 19. The output end of the first hydraulic cylinder 19 first adjusts the height of the second hydraulic cylinder 21 through the connecting support plate 20. Then, the output end of the second hydraulic cylinder 21 moves the lifting rod 23 through the movable plate 22 until it moves to the bottom of the container. Then, the first hydraulic cylinder 19 drives the second hydraulic cylinder 21 to rise so that it can lift the container. Then, the second hydraulic cylinder 21 moves the container to the discharge support plate 9. Then, the first hydraulic cylinder 19 lowers its height so that the second hydraulic cylinder 21 can place the container on the discharge support plate 9, so that the equipment can automatically discharge materials, thereby reducing the workload of the workers.

[0028] In summary, this kiln structure for aluminum ore smelting, through the cooperation of the kiln body 1, heater 2, fixing frame 3, drive motor 4, threaded rod 5, connecting screw plate 6, kiln door panel 7, placement tray 8, material feeding support plate 9, and feeding mechanism 10, solves the problem of not being able to automatically process ore feeding, requiring manual feeding operations during use, and lacking the function of processing heat in flue gas, resulting in a large amount of heat being emitted into the air during flue gas discharge.
