Description

Technical Field

[0001] This utility model belongs to the field of ingot processing, and specifically relates to a structure for cleaning aluminum slag at the water inlet of a smelting furnace. Background Technology

[0002] In aluminum smelting, molten aluminum needs to be replenished to the furnace periodically. Traditionally, the water inlet is located on the side of the furnace and uses an open funnel or inclined trough structure. When the molten aluminum flows through the water inlet, it oxidizes upon contact with air, forming slag. Some of the molten aluminum remains on the inner wall of the water inlet due to temperature drop, forming hardened aluminum slag. The machine must be stopped after every 2-3 additions of material, and then the slag must be removed manually or using slag removal equipment. To improve the hardening effect of the molten aluminum caused by temperature drop, such as… Figure 1 As shown, a sealable feed tank 2 is designed on the side of the smelting furnace 1. By sealing the feed tank 2 after adding molten aluminum, the temperature inside the smelting furnace 1 can radiate to the feed tank 2, reducing heat loss inside the feed tank 2. This allows the molten aluminum remaining in the feed tank 2 to continue flowing into the smelting furnace 1, reducing the accumulation and hardening of aluminum slag.

[0003] While the above-mentioned method can significantly reduce the generation of aluminum dross, it is difficult to completely avoid it. During the addition of molten aluminum, the aluminum is easily oxidized upon contact with air, forming dross that remains in the feed tank 2. Furthermore, the volatiles of the refining solvent may condense on the tank wall and combine with the initial dross alumina to form a dross layer. Therefore, although the frequency of dross layer cleaning can be greatly reduced, it cannot be completely avoided. When dross layer cleaning is necessary, the temperature of the smelting furnace 1 and feed tank 2 is generally lowered to a safe range before the dross layer is removed from the inner wall of feed tank 2 by tapping or scraping. During this process, the detached dross pieces fall to the bottom of feed tank 2 and are then scooped out.

[0004] To facilitate feeding and sealing of the feed tank 2, the opening of the feed tank 2 faces upward. This results in a horizontal bend 3 between the feed tank 2 and the smelting furnace 1. Furthermore, to facilitate the flow of molten aluminum into the smelting furnace 1, the bottom of the feed tank 2 is inclined. Consequently, falling slag will enter the bend 3 along the inclined bottom of the feed tank 2. When removing the slag, the long handle of a conventional slag shovel is rigid and difficult to enter the channel between the feed tank 2 and the smelting furnace 1 to remove the slag. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an aluminum slag cleaning structure for the water inlet of a smelting furnace, which solves the problem that the long handle of conventional slag shovels is rigid and difficult to enter the channel between the feed tank and the smelting furnace to remove slag.

[0006] According to the embodiments of this utility model, the following technical solution is adopted:

[0007] A slag cleaning structure for the water inlet of a smelting furnace includes a slag scraper. The slag scraper includes a first rod, a second rod hinged to the first rod, and a scraper installed at the end of the second rod. A limiting cylinder is fitted on the first rod, and a limiting ring for limiting the limiting cylinder is installed on the second rod. A connecting rope is fixed between the limiting cylinder and the second rod. When the end of the limiting cylinder and the limiting ring abut against each other, the limiting cylinder is fitted at the connection between the first rod and the second rod, and the connecting rope is in a slack state.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] When the end of the limiting cylinder abuts against the limiting ring, it restricts the relative deflection of the first and second rods, allowing the slag scraper to be used directly. However, when the water inlet has a corner, moving the limiting cylinder so that it no longer obstructs the relative deflection of the first and second rods, and continuing to move the limiting cylinder after the connecting rope is taut, allows the second rod to deflect and the angle of deflection to be adjusted, enabling the second rod to drive the scraper to extend into the corner for slag removal.

[0010] Furthermore, the limiting cylinder includes a first section and a second section rotatably connected to the first section. The first section and the first rod are threadedly connected, and the connecting rope is connected to the second section.

[0011] Furthermore, a slider is fixed to the inner wall of the second section near the end of the first section. The slider is slidably connected to the first rod, and the first rod has a groove for the slider to slide.

[0012] Furthermore, the second section includes a sliding part and a movable part detachably connected to the sliding part, with a connecting rope connected to the movable part.

[0013] Furthermore, the second rod has connecting rings fixed on both sides along its radial direction for binding with the connecting rope.

[0014] Furthermore, an obtuse angle is formed between the center line of the scraper along its width direction and the axis of the second rod.

[0015] Furthermore, a sleeve is fixed to the end of the scraper, and a rod for inserting into the sleeve is fixed to the end of the second rod. A limiting block for limiting the position of the sleeve is fixed to the end of the rod. A limiting element for limiting the position of the sleeve is provided on the rod or the limiting block.

[0016] Furthermore, the limiting component includes a threaded hole on the limiting block, several insertion holes along the circumference of the sleeve, and a limiting rod for threaded connection in the threaded hole and insertion into the insertion hole. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given.

[0024] like Figure 2 As shown, the aluminum slag cleaning structure at the water inlet of the smelting furnace includes a slag scraper. The slag scraper includes a first rod 4, a second rod 5 hinged to the first rod 4, and a scraper 6 installed at the end of the second rod 5. The scraper 6 can be designed as a plate or a fork, depending on the actual needs.

[0025] A limiting cylinder 11 is fitted onto the first rod 4, and a limiting ring 12 is installed on the second rod 5 to limit the limiting cylinder 11. A connecting rope 14 is fixed between the limiting cylinder 11 and the second rod 5. When the end of the limiting cylinder 11 abuts against the limiting ring 12, the limiting cylinder 11 is fitted at the connection between the first rod 4 and the second rod 5, and the connecting rope 14 is in a slack state. At this time, the limiting cylinder 11 can be moved. Since the connecting rope 14 is in a slack state, it will not pull the second rod 5 to swing, thus preventing the second rod 5 from being restricted from swinging before the limiting cylinder 11 has disengaged from the connection between the first rod 4 and the second rod 5. When the limiting cylinder 11 has completely moved onto the first rod 4, the second rod 5 can be pulled to deflect. Adjusting the angle of deflection of the second rod 5 allows the second rod 5 to drive the scraper 6 to extend into the corner 3 to remove slag. Figure 4 The state shown is as indicated. Of course, if adjusting the relative deflection of the first rod 4 and the second rod 5 is sufficient to allow the scraper 6 to extend into the corner 3, no adjustment is necessary. Figure 2 The image shows the unadjusted state, but the scraper 6 is difficult to reach the far right of corner 3.

[0026] In another embodiment of this utility model, combined with Figure 3 As shown, in order to ensure that the limiting cylinder 11 can remain stationary on the first rod 4 after being moved to a suitable position, the limiting cylinder 11 includes a first section 7 and a second section 10 rotatably connected to the first section 7. The first section 7 and the first rod 4 are threadedly connected, and the connecting rope 14 is connected to the second section 10. By rotating the first section 7, the limiting cylinder 11 can move on the first rod 4, while the first section 7 rotates relative to the second section 10, so that the second section 10 can only move without rotating, thus preventing the second section 10 from causing the connecting rope 14 to become entangled on the first rod 4.

[0027] To further restrict the movement of the second segment 10, a slider 16 is fixed to the inner wall of the end of the second segment 10 near the first segment 7. The slider 16 is slidably connected to the first rod 4. The first rod 4 has a groove 15 for the slider 16 to slide. By restricting the second segment 10 to only slide, the second segment 10 can be prevented from causing the connecting rope 14 to get tangled on the first rod 4.

[0028] In another embodiment of this utility model, the second segment 10 includes a sliding part 8 and a movable part 9 detachably connected to the sliding part 8. The connecting rope 14 is connected to the movable part 9, and the second rod 5 has connecting rings 13 fixed on both sides of its radial direction for binding with the connecting rope 14. In this solution, the sliding part 8 and the movable part 9 each have two threaded holes on their radial direction. When the threaded holes on the sliding part 8 and the movable part 9 are aligned, the bolt can be connected into the threaded holes. In actual operation, by rotating the movable part 9 180°, the connecting rope 14 can be positioned on both sides of the limiting cylinder 11. Then, by controlling the binding of the connecting rope 14 with different connecting rings 13, the position of the connecting rope 14 can be controlled. Thus, when the second rod 5 is pulled to deflect, the second rod 5 can be pulled to deflect in two directions, and assembly can be performed according to actual needs.

[0029] In another embodiment of this utility model, the scraper 6 forms an obtuse angle between its center line along its width direction and the axis of the second rod 5. Therefore, when the scraper 6 is inserted into the feed tank 2 and the corner 3, the free end of the scraper 6 is more likely to contact the very end of the corner 3. Figure 4 The rightmost corner at the bottom of corner 3 shown in the diagram.

[0030] In another embodiment of this utility model, combined with Figure 5 As shown, in order to facilitate the adjustment of the angle of the scraper 6, a sleeve 18 is fixed to the end of the scraper 6, and an insertion rod 17 for inserting into the sleeve 18 is fixed to the end of the second rod 5. A limiting block 19 for limiting the sleeve 18 is fixed to the end of the insertion rod 17 to prevent the sleeve 18 and the insertion rod 17 from separating.

[0031] The insert rod 17 or the limiting block 19 is provided with a limiting member for limiting the position of the sleeve 18. In this embodiment, the limiting member includes a threaded hole opened on the limiting block 19, a plurality of insertion holes 20 opened along the circumference of the sleeve 18, and a limiting rod 21 for threaded connection in the threaded hole and inserted into the insertion hole 20. By inserting the limiting rod 21 into different insertion holes 20, the scraper 6 and the second rod 5 can be at different angles, so as to better remove slag.
