Description

Technical Field

[0001] This utility model relates to the field of crucible technology, and in particular to a long magnesium alloy crucible with divisible cavities. Background Technology

[0002] A crucible is a container specifically used for heating solids at high temperatures. The most crucial step in the magnesium alloy forming process is refining. After the primary magnesium is melted, it is pumped through the crucible into the next alloy production process. Therefore, the quality of the primary magnesium directly affects the final magnesium alloy product. Different magnesium alloy products have different quality requirements, and thus different purity requirements for the molten magnesium. For example, AS series alloy products require the crucible to be cleaned after each batch; otherwise, silicon will settle, affecting the crucible's thermal conductivity and posing a safety hazard. Furthermore, this series of products requires high purity, corrosion resistance, and mechanical properties; failure to clean the crucible promptly will directly impact the quality and performance of the final magnesium alloy product. Utility Model Content

[0003] This invention relates to a long magnesium alloy crucible with compartments, designed to ensure the quality and performance of magnesium alloy products.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a magnesium alloy long crucible with divisible cavities, comprising a crucible body, a support base being snapped onto one side of the outer surface of the crucible body, a base being rotatably connected to the top of the support base, a screw lifting assembly being installed on the top of the base, and a movable frame being fixedly installed on the movable end of the screw lifting assembly;

[0005] The bottom of the movable frame is symmetrically connected to two movable partitions, which are inserted into the inside of the crucible body and fit tightly against the inner wall of the crucible body.

[0006] A limit assembly is installed between the top of the crucible body and the screw lifting assembly. Two vertically arranged movable partitions divide the interior of the crucible into three chambers, enabling multi-stage sedimentation of the magnesium liquid and improving its purity.

[0007] Furthermore, the screw lifting assembly includes a fixed frame, which is fixedly installed on the top of the base. A handwheel is provided on the top of the fixed frame, and a screw body is fixedly connected to the bottom of the handwheel. The screw body passes through the fixed frame and is rotatably connected to it. A slide is threaded onto the outer surface of the screw body. The handwheel facilitates manual rotation of the screw body. The screw lifting assembly allows for the overall lifting and disassembly of movable partitions.

[0008] Furthermore, slide rails are fixedly connected to both inner walls of the fixed frame, and the slide block is slidably connected to the slide rail. The slide rail has a limiting effect on the slide block, which can ensure the stability of the slide block's movement.

[0009] Furthermore, the movable frame includes a tripod, which is fixedly connected to the slide. Two crossbars are symmetrically fixedly connected to the bottom of the tripod, and these crossbars engage with the movable partitions. This movable frame design facilitates the vertical movement and disassembly of the two movable partitions by the slide. Since the crossbars and movable partitions are engaged, after the two movable partitions are vertically installed, the support base, base, and movable frame can slide horizontally out, allowing the crucible with the movable partitions installed to be used in normal production. When cleaning the crucible, the crossbars are pushed horizontally in and engage with the upper edge of the movable partitions, allowing the screw lifting assembly to rise and pull out the two movable partitions for easy cleaning.

[0010] Furthermore, the limiting component includes a limiting baffle, which is fixedly connected to the fixing frame. One side of the outer surface of the limiting baffle abuts against a limiting block, which is fixedly connected to the crucible body. The limiting block and the limiting baffle limit the movement of the base when it rotates, thereby improving the performance.

[0011] Furthermore, the inner wall of the crucible body is provided with a guide groove along the vertical direction for inserting a movable partition. The guide groove serves two purposes: firstly, it facilitates the insertion and removal of the movable partition; secondly, it helps to fix the movable partition in place.

[0012] Furthermore, multiple lifting rings are symmetrically fixedly installed on the top of the crucible body to facilitate the lifting of the entire structure using external lifting equipment.

[0013] Furthermore, one of the movable partitions has a first overflow port extending to the other side on one side of its outer surface, and the other movable partition has a second overflow port extending to the other side on one side of its outer surface. The first overflow port is higher than the second overflow port, and the overflow port can be used to determine the overflow direction. The two movable partitions divide the interior of the crucible into three chambers. The first chamber on the side where the first overflow port is located is the pumping direction for the magnesium liquid. The magnesium liquid precipitates through the three chambers in sequence before being pumped out.

[0014] The beneficial effects of this utility model are:

[0015] 1. The device of this utility model uses a movable partition to divide the inside of the crucible into three chambers, forming a three-stage precipitation process. After the magnesium liquid undergoes three-stage precipitation, the purity of the pumped magnesium liquid can be effectively improved, ensuring the production quality of subsequent magnesium alloy products.

[0016] 2. The movable partition is detachable, which reduces the difficulty of slag removal and makes it easy to disassemble and clean the crucible. The movable partition is also designed to be detachable, so that the same crucible can be used in the production process of multiple magnesium alloy products, realizing one pot for multiple uses.

[0017] 3. The movable partition can be quickly disassembled and assembled by using the support base, screw lifting assembly and movable frame, which improves the slag removal efficiency. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 3 As shown, a long magnesium alloy crucible with a compartmentalized structure is disclosed, comprising a crucible body 1, a support base 4 being snapped onto the outer edge of the top of the crucible body 1, a base 16 being rotatably connected to the top of the support base 4, a screw lifting assembly being mounted on the top of the base 16, the screw lifting assembly including a fixing frame 6, the fixing frame 6 being fixedly mounted on the top of the base 16, a handwheel 7 being provided on the top of the fixing frame 6, a screw body 12 being fixedly connected to the bottom of the handwheel 7, the screw body 12 being disposed through the fixing frame 6 and rotatably connected thereto, a slide block 13 being threaded onto the outer surface of the screw body 12, and slide rails 11 being fixedly connected to the inner walls on both sides of the fixing frame 6, and the slide block 13 being slidably connected to the slide rails 11, the slide rails 11 being provided to ensure the stability of the movement of the slide block 13.

[0026] A movable frame is fixedly installed at the movable end of the screw lifting assembly. Two movable partitions 9 are symmetrically connected to the bottom of the movable frame. The movable partitions 9 are inserted into the inside of the crucible body 1 through guide slots and fit tightly against the inner wall, forming three chambers inside the crucible. Metal gaskets are installed on the outer surface of the movable partitions 9 to ensure the sealing of the connection between the crucible body 1 and the movable partitions 9. At the same time, the bottom edges of the movable partitions 9 and the inner bottom edge of the crucible body 1 are rounded to ensure the insertion effect. The movable frame includes a tripod 5, which is fixedly connected to the slide 13. Two crossbars 10 are symmetrically connected to the bottom of the tripod 5, and the crossbars 10 are engaged with the top of the movable partitions 9. The movable frame facilitates the lifting and lowering of the two movable partitions 9 by the screw lifting assembly.

[0027] A limiting component is installed between the top of the crucible body 1 and the screw lifting assembly. The limiting component includes a limiting baffle 14, which is fixedly connected to the fixing frame 6. One side of the outer surface of the limiting baffle 14 abuts against a limiting block 8, which is fixedly connected to the crucible body 1. The limiting baffle 14 and the limiting block 8 work together to ensure that when the base 16 rotates, the movable partition 9 is exactly above the crucible body 1.

[0028] Multiple lifting rings 15 are symmetrically fixedly installed on the top of the crucible body 1. The arrangement of the lifting rings 15 facilitates the lifting operation.

[0029] A first overflow port 2 extending to the other side is provided on one side of the outer surface of a single movable partition 9, and a second overflow port 3 extending to the other side is provided on one side of the outer surface of another single movable partition 9. The first overflow port 2 is higher than the second overflow port 3. The two movable partitions 9 divide the interior of the crucible body 1 into a preliminary settling chamber, a settling chamber and a casting chamber. Molten magnesium enters the preliminary settling chamber from the right side, then enters the settling chamber through the first overflow port 2, then enters the casting chamber through the second overflow port 3, and finally is pumped out to the next production process.

[0030] Working principle: When slag removal is required, turn the handwheel 7. The handwheel 7 drives the screw body 12 to rotate. The screw body 12 drives the slide 13 to rise along the slide rail 11. The slide 13 drives the two crossbars 10 to rise through the tripod 5. The crossbars 10 drive the movable partition 9 to rise until the movable partition 9 is completely pulled out. The fixed frame 6 drives the base 16 and other components to rotate until the movable partition 9 moves to one side of the crucible body 1, and then the slag removal operation is performed. Similarly, the support base 4 and the top of the crucible body are designed to be snapped together. Therefore, during the slag removal or magnesium liquid sedimentation process, the support base, screw lifting assembly and movable frame can be disassembled as a whole.
