The material shows good corrosion resistance in the atmospheric environment, and the waste recovery rate can reach more than 95%, but there are inherent defects such as low room temperature creep strength (< 30 MPa) and poor long-term dimensional stability (natural aging shrinkage rate about 0.1-0.3%). In industrial production, zinc alloy needs to be heated to 50-80 DEG C above the liquidus by a furnace for smelting, and then the zinc slag containing impurities (temperature about 420-450 DEG C) needs to be transported to the pretreatment section.

[0021] 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.

[0022] Please see Figures 1-5This utility model provides an embodiment of a molten metal anti-splash mechanism for zinc alloy production, comprising a smelting furnace 2 for processing aluminum alloys. The smelting furnace 2 is mounted on mounting brackets 5 via a rotating mechanism. The bottom ends of the two mounting brackets 5 are screwed or welded to a base plate 1 to ensure stability. The rotating mechanism allows for easy rotation and tilting of the smelting furnace 2 for easy pouring. A groove adapted to a discharge port 7 is provided at the top front end of the smelting furnace 2. The discharge port 7 can be welded to the smelting furnace 2 or integrally formed. To prevent splashing during pouring, symmetrical insertion slots 13 for anti-splash components are provided at one end of the discharge port 7 near the smelting furnace 2. Insertion blocks 15 are inserted into the insertion slots 13. A baffle 12 is provided between the two insertion blocks 15 for rotation (rotational connection can be achieved through a rotating rod, etc.). The baffle 12 is conveniently installed and fixed without affecting use and facilitates subsequent installation. For disassembly, cleaning, or replacement, fixing screws 16 (composed of threaded rods and nuts) for mounting components are welded to the side walls of the two plug-in blocks 15 that are far apart from each other. A positioning block 14 is welded to the corresponding side wall of the smelting furnace 2. The positioning block 14 has a slot to facilitate the insertion of the threaded rod in the fixing screw 16. At the same time, a washer 17 is provided on the threaded rod. The nut that cooperates with the fixing screw 16 can be tightened with the positioning block 14 to complete the installation and fixation. During the rotation and tilting process, the zinc alloy solution flows out with the discharge port 7, which in turn generates an upward force on the end baffle 12 (the end away from the smelting furnace 2). At the same time, as the smelting furnace 2 rotates and tilts, the cross-sectional area of ​​the discharge port 7 gradually increases from the initial tilt. The increase in the cross-sectional area of ​​the discharge port can reduce the flow rate (when the flow rate is constant, the flow rate is inversely proportional to the cross-sectional area). The lower flow rate reduces the direct impact of the liquid on the receiving surface, thereby reducing the risk of splashing.

[0023] Please see Figures 1-5 To facilitate the rotation and tilting of the smelting furnace 2, and also for easy resetting, arc-shaped fixing plates 9 with rotating mechanisms are installed on both side walls of the smelting furnace 2 via screws or welding. A rotating shaft 11 is rotatably mounted in the middle of the outer arc surface of the arc-shaped fixing plate 9. The rotating shaft 11 is connected to the mounting bracket 5 via a bearing seat (which can be fixed with screws). One of the rotating shafts 11 is fixedly connected to the output end of the motor 6 via a coupling. A fixing bracket 10 is externally fixed to the motor 6 (via bolts). The bottom end of the fixing bracket 10 is connected to the motor 6. The mounting bracket 5 is fixedly connected (by bolts or welding), and a vertical plate 3 is vertically welded to the rear end of the base plate 1. The vertical plate 3 has an L-shaped cross section, and an adjustment box 4 of the auxiliary mechanism is symmetrically welded below the top horizontal section of the vertical plate 3. Inside the adjustment box 4, a rotating rod 19 is provided through a spiral spring 21. A rope winder 20 is provided in the middle of the rotating rod 19. The rope winder 20 winds up the pull rope 8 of the connecting component. The end of the pull rope 8 is attached to a connecting ring 18 (or connected by a hook, etc.). The connecting ring 18 is welded to the side wall of the rear end of the smelting furnace 2.

[0024] Working Principle: When using this utility model, to install the baffle 12, the plug-in block 15 is inserted into the plug-in slot 13. After insertion, the threaded rod on the fixing screw 16 enters the slot of the positioning block 14. Then, the nut of the fixing screw 16 is tightened in conjunction with the washer 17 to complete the assembly and fixation. When pouring the zinc alloy molten liquid in the smelting furnace 2, the motor 6 rotates clockwise, which, together with the rotating shaft 11 and the arc-shaped fixing plate 9, causes the smelting furnace 2 to rotate and tilt. At this time, the pull rope 8 moves upward with the rotation of the smelting furnace 2. Under the action of the spiral spring 21 winding and storing potential energy, the rotating rod 19 and the rope winder 20 rotate and reset, which can wind up the pull rope 8. During the rotation and tilting process, the zinc alloy liquid flows out with the discharge port 7, which in turn generates an upward force on the baffle 12 at the end (away from the end of the smelting furnace 2). As the smelting furnace 2 rotates and tilts, the cross-sectional area of ​​the discharge port 7 gradually increases from the initial tilt. The increased cross-sectional area of ​​the discharge port reduces the flow velocity (when the flow rate is constant, the flow velocity is inversely proportional to the cross-sectional area). The lower flow velocity reduces the direct impact of the liquid on the receiving surface, thereby reducing the risk of splashing. After tilting, the smelting furnace 2 can be rotated and reset by rotating the motor 6 counterclockwise. At this time, the pull rope 8 is stretched, and the rope winder 20 releases the rope 8, causing the rotating rod 19 to rotate. The spiral spring 21 winds up and stores potential energy, which can play an auxiliary traction role in the rotation reset process, ensuring slow and stable rotation. When it is necessary to clean or replace the baffle 12, the nut on the fixing screw 16 is unscrewed, and the fixing screw 16 is lifted upwards, so that the plug block 15 can be removed from the plug slot 13, thereby completing the disassembly of the baffle 12 for easy cleaning or replacement.
