Description

Technical Field

[0001] This utility model relates to the field of aluminum ingot production equipment, and in particular to a smelting furnace for aluminum ingot processing. Background Technology

[0002] In the smelting process of aluminum ingot processing, the smelting furnace is one of the core pieces of equipment. Its function is to heat the aluminum ingot raw material to a molten state for subsequent casting or forming processing. During the smelting process, in order to effectively remove impurities and oxides from the molten aluminum, a filter frame structure is usually installed in the smelting furnace to purify the flowing aluminum liquid using a filter medium.

[0003] Currently, most traditional smelting furnaces use fixed or bolted connections for their filter frames, which are installed in specific locations inside the furnace. When cleaning or replacing the filter frames is necessary, operators often need specialized tools to disassemble multiple fasteners and work within the confined or high-temperature furnace space, a cumbersome and time-consuming process. A more significant problem is that, due to the long-term exposure to high temperatures, the metal components of the filter frames are prone to thermal expansion or oxidation and adhesion, making disassembly difficult. Forced disassembly can easily damage the furnace structure or the filter frame itself. This inconvenient design severely restricts equipment maintenance efficiency, increases downtime, hinders the efficient operation of the production line, and fails to meet the demands of the modern aluminum processing industry for continuous and high-efficiency production. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a smelting furnace for aluminum ingot processing, aiming to improve the problems of inconvenient disassembly, maintenance and replacement of filter frames in existing aluminum ingot processing smelting furnaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a smelting furnace for aluminum ingot processing, comprising a furnace body, with fixed frames fixedly connected to both sides of the upper part of the furnace body, connecting rods slidably connected inside the two fixed frames, filter frames fixedly connected to the bottom of the two connecting rods, fixed boxes fixedly connected to the outside of the two fixed frames, movable plates slidably connected inside the two fixed boxes, insert plates fixedly connected to one side of the two movable plates, the two insert plates slidably connected inside the connecting rods, pull rods fixedly connected to the upper parts of the two movable plates, and fixed components slidably connected inside the two connecting rods and insert plates, the fixed components being used to fix the connecting rods and insert plates, one end of a return spring fixedly connected to both sides of the inside of the two fixed boxes, and the other ends of multiple return springs fixedly connected to the other side of the two movable plates.

[0006] Furthermore, an installation ring is fixedly connected to the outside of the furnace body, and an installation frame is fixedly connected to the outer perimeter of the installation ring. A screw is threadedly connected to the inside of each of the multiple installation frames. A throttle handle is fixedly connected to one end of each of the multiple screws, and a positioning block is threadedly connected to the other end of each of the multiple screws. A cover is provided on the upper part of the furnace body, and a positioning plate is fixedly connected to the bottom perimeter of the cover. The positioning blocks are slidably connected to the inside of the positioning plate.

[0007] Furthermore, the fixing component includes a limiting rod and a locking rod, with both limiting rods slidably connected inside the connecting rod and the insert plate, and multiple locking rods fixedly connected to the outer sides of the limiting rods.

[0008] Furthermore, pressure plates are rotatably connected to the upper parts of both fixed frames, and the two limiting rods are slidably connected inside the pressure plates.

[0009] Furthermore, both of the connecting rods have cavities inside, both of the limiting rods are rotatably connected inside the cavities, and multiple locking rods are rotatably connected inside the cavities.

[0010] Furthermore, both of the insert plates are slidably connected inside the fixed box, and both of the insert plates are slidably connected inside the fixed frame.

[0011] Furthermore, the mounting ring has insertion holes on all four sides, and multiple positioning plates are slidably connected inside the insertion holes.

[0012] Furthermore, each of the multiple positioning plates has a positioning hole inside, and the multiple positioning blocks are slidably connected inside the positioning hole.

[0014] 1. In this utility model, by pulling the pull rod to make the moving plate slide, compressing the reset spring, driving the insert plate to exit the connecting rod, rotating the limit rod, and making the locking rod rotate 90 degrees and then pull it upward to release the fixation, flipping the pressure plate, the filter frame can be lifted upward, realizing easy disassembly of the filter frame, convenient maintenance and replacement, reducing cleaning time, and ensuring smelting efficiency.

[0015] In this invention, rotating the handle drives the screw to rotate, causing the positioning block to exit from the positioning hole, and the cover can be easily removed. This facilitates easy disassembly of the cover, makes inspection and maintenance convenient, reduces downtime, and allows for timely detection and handling of problems, ensuring stable operation of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a smelting furnace for aluminum ingot processing, comprising a furnace body 1. Fixed frames 12 are fixedly connected to both sides of the upper part of the furnace body 1. Connecting rods 11 are slidably connected inside each of the two fixed frames 12. Filter frames 10 are fixedly connected to the bottom of each of the two connecting rods 11. Fixed boxes 16 are fixedly connected to the outside of each of the two fixed frames 12. Moving plates 17 are slidably connected inside each of the two fixed boxes 16. Insert plates 18 are fixedly connected to one side of each of the two moving plates 17. The two insert plates 18 are slidably connected inside the connecting rods 11. Pull rods 19 are fixedly connected to the upper part of each of the two moving plates 17. Fixing components are slidably connected inside the two connecting rods 11 and the insert plates 18. The fixing components are used to fix the connecting rods 11 and the insert plates 18. The two fixed boxes 16... Both sides of the interior are fixedly connected to one end of a return spring 20, and the other ends of multiple return springs 20 are fixedly connected to the other side of two moving plates 17. The fixing assembly includes a limiting rod 14 and a locking rod 15. Both limiting rods 14 are slidably connected to the interior of the connecting rod 11 and the insert plate 18. Multiple locking rods 15 are fixedly connected to the outer sides of the limiting rods 14. The upper part of both fixing frames 12 is rotatably connected to a pressure plate 13. Both limiting rods 14 are slidably connected to the interior of the pressure plate 13. Both connecting rods 11 have cavities inside. Both limiting rods 14 are rotatably connected to the interior of the cavities. Multiple locking rods 15 are rotatably connected to the interior of the cavities. Both insert plates 18 are slidably connected to the interior of the fixing box 16. Both insert plates 18 are slidably connected to the interior of the fixing frame 12.

[0025] The filter frame 10 is used to intercept and filter solid impurities during the aluminum molten metal smelting process, ensuring the purity of the aluminum molten metal. Simultaneously, the intercepted impurities can be removed along with the filter frame for easy centralized cleaning. When the filter frame 10 needs to be removed, first pull the lever 19, causing the moving plate 17 to slide within the fixed box 16. The fixed box 16 accommodates the moving plate 17, serving as its sliding track. The return spring 20 stores elastic potential energy when the moving plate 17 slides and compresses. When the external force is removed, it pushes the moving plate 17 to reset, causing the insert plate 18 to automatically return to its original position. The insert plate 18 then exits from the connecting rod 11, releasing the fixation of the connecting rod 11. Subsequently, the operator rotates the limiting rod 14, which is used to operate the rotation and lifting of the locking rod 15. The rotation of the locking rod 15 causes the limiting rod 14 to rotate within the cavity of the insert plate 18. After the locking rod 15 rotates 90 degrees, the two limiting rods 14 are pulled up, removing the limiting rods 14 and locking rod 15 from the connecting rod 11 and insert plate 18, and moving them out of the pressure plate 13, thus releasing the fixation of the connecting rod 11 and insert plate 18. Then, the pressure plate 13 is rotated so that it leaves the upper part of the connecting rod 11 and covers the upper part of the connecting rod 11. Its rotation can release or restrict the upward movement path of the connecting rod 11, achieving multiple fixation in conjunction with other structures to prevent accidental loosening. Subsequently, the two connecting rods 11 can be pulled up directly, causing the filter frame 10 to move upward from inside the furnace body 1.

[0026] Reference Figure 2 and Figure 4 The furnace body 1 is externally fixedly connected to an installation ring 2. The installation ring 2 is fixedly connected to an installation frame 4 around its outer perimeter. The installation frames 4 are threadedly connected to screws 6 inside each of the multiple installation frames 4. One end of each screw 6 is fixedly connected to a handle 5. The other end of each screw 6 is threadedly connected to a positioning block 7. The upper part of the furnace body 1 is provided with a cover 3. The bottom of the cover 3 is fixedly connected to a positioning plate 8 around its outer perimeter. The positioning blocks 7 are slidably connected inside the positioning plate 8. The installation ring 2 has insertion holes around its inner perimeter. The positioning plates 8 are slidably connected inside the insertion holes. The positioning plates 8 have positioning holes 9 inside their respective interiors. The positioning blocks 7 are slidably connected inside the positioning holes 9.

[0027] Mounting ring 2 is used to mount positioning plate 8 and cover 3. Cover 3 seals the top of furnace body 1 to prevent heat loss and impurities from entering during the smelting process. Rotating handle 5 drives screw 6 to rotate within mounting frame 4, causing positioning block 7 to exit from positioning hole 9 of positioning plate 8. Positioning hole 9 is set on positioning plate 8 to accommodate positioning block 7. Since positioning plate 8 is slidably connected in the insertion hole of mounting ring 2, cover 3 can be easily lifted upwards after being released from fixation. After disassembly, the interior of furnace body 1 is completely exposed. Furnace body 1 is the main structure of smelting furnace, containing molten aluminum and filter frame 10.

[0028] Working principle: When the filter frame 10 needs to be removed, first pull the lever 19, causing the moving plate 17 to slide within the fixed box 16. At this time, the return spring 20 is compressed, providing a return force, causing the insert plate 18 to exit from the connecting rod 11, releasing the fixation of the connecting rod 11. Subsequently, the operator rotates the limiting lever 14, which causes the locking lever 15 to rotate within the cavity of the insert plate 18. After the locking lever 15 rotates 90 degrees, pull up both limiting levers 14 to remove them from the connecting rod 11 and the insert plate 18, and remove them from the pressure plate 13, releasing the fixation of the connecting rod 11 and the insert plate 18. Next, rotate the pressure plate 13 to move it away from the upper part of the connecting rod 11. Then, the two connecting rods 11 can be pulled upwards directly, moving the filter frame. The filter frame 10 moves upward from inside the furnace body 1. Since the filter frame 10 intercepts impurities in the molten aluminum during the smelting process, removing it upwards can bring the impurities out with it, making cleaning easier. This facilitates the disassembly of the filter frame 10, making it easier to maintain and replace, reducing cleaning time, ensuring the normal operation of the smelting furnace, and improving work efficiency. Rotating the handle 5 drives the screw 6 to rotate within the mounting frame 4, causing the positioning block 7 to exit from the positioning hole 9 of the positioning plate 8. Since the positioning plate 8 is slidably connected in the insertion hole of the mounting ring 2, after the fixation is released, the cover 3 can be easily lifted upwards. After disassembly, the interior of the furnace body 1 is completely exposed, facilitating the disassembly of the cover 3. This reduces the downtime of the smelting furnace and makes it easier to periodically inspect and monitor the internal condition of the furnace body 1, helping to identify and solve problems in a timely manner.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
