Description

Technical Field

[0001] This utility model relates to the field of crucibles, and more particularly to an electron beam anti-climb crucible. Background Technology

[0002] Electron beam melting technology is a key process widely used in the preparation of high-purity metal materials, and the graphite crucible, as its core component, needs to maintain stable performance in extreme high-temperature (usually exceeding 2000℃) and highly corrosive environments.

[0003] Existing technologies, such as the utility model patent with publication number CN222274665U, disclose a crucible and an electron beam evaporation coating system. This patent employs a crucible body, which is an anti-climbing crucible body with holes. A conductive element is disposed within the holes, with a portion of the conductive element exposed within the inner cavity of the crucible body. During electron beam evaporation, the coating solution comes into partial contact with the conductive element, allowing current to be transmitted through the conductive element and preventing charge accumulation. Simultaneously, because the crucible body is an anti-climbing crucible body, it possesses anti-climbing properties, meaning that the coating material placed inside the crucible body has poor or no wettability on the surface of the crucible body, preventing the coating material from climbing the crucible body or causing it to climb very slowly, thus preventing the coating material from overflowing the crucible.

[0004] The inventors discovered in daily use that existing graphite crucibles, also known as copper melting pots or copper melting crucibles, are a type of crucible made from graphite, clay, silica, and wax stone. Graphite crucibles are mainly used to smelt non-ferrous metals and their alloys, such as copper, brass, gold, silver, zinc, and lead. High-purity graphite crucibles have characteristics such as low impurity content, high temperature resistance, oxidation resistance, and resistance to metal solution corrosion. However, when melting metals using electron beam equipment, high-energy impacts and non-wetting surfaces often cause liquid metal to climb out of the crucible and penetrate into the interior, resulting in overall crucible damage and material waste. Furthermore, traditional crucibles are susceptible to external contamination due to their open design.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies.

[0007] To solve the above-mentioned technical problems, this utility model provides an electron beam anti-climb crucible, comprising: an outer shell, a crucible body installed inside the outer shell, an auxiliary structure provided on the arc surface of the outer shell, the auxiliary structure including a fixing rod, the fixing rod being fixedly connected to the outer shell, a sleeve rod being rotatably connected to the upper end of the fixing rod, a slip ring being slidably connected to the arc surface of the sleeve rod, a plurality of insert rods being fixedly connected to the lower surface of the slip ring, a fixing ring being fixedly connected to the arc surface of the fixing rod, a plurality of insertion holes being opened on the inner wall of the fixing ring, the insert rods being adapted to the insertion holes, a screw being slidably connected to the inner wall of the sleeve rod, a connecting rod being fixedly connected to the upper end of the screw rod, a protective plate being fixedly connected to the upper end of the connecting rod, and a threaded ring being rotatably connected to the upper end of the sleeve rod, the threaded ring being threadedly connected to the screw rod.

[0008] The aforementioned components achieve the following effects: When protection of the crucible body is required, pulling the slip ring moves the insert rod, which slides on the arc surface of the sleeve rod. The insert rod then separates from the insertion hole on the fixed ring. Rotating the slip ring moves the sleeve rod, which rotates at the upper end of the fixed rod. The sleeve rod then moves the screw, which moves the connecting rod. The connecting rod moves the protective plate, placing it above the crucible body. The insert rod on the slip ring is then aligned with the insertion hole on the fixed ring. Moving the slip ring downwards causes the insert rod to be inserted into the insertion hole for fixation. When the height of the protective plate needs adjustment, rotating the threaded ring moves the screw, which slides on the inner wall of the sleeve rod. The screw moves the connecting rod, which in turn moves the protective plate, thus adjusting its height.

[0009] Preferably, the arc surface of the threaded ring is provided with a plurality of slots, and the plurality of slots are evenly distributed on the threaded ring.

[0010] The effect achieved by the above components is that the groove can increase the friction between the hand and the threaded ring, preventing slippage when rotating the threaded ring.

[0011] Preferably, a plurality of levers are fixedly connected to the arc surface of the slip ring, and the plurality of levers are evenly distributed on the slip ring.

[0012] The effect achieved by the above components is that when it is necessary to move the slip ring, the lever can be turned directly, and the lever will drive the slip ring to move, making it more convenient to move the slip ring.

[0013] Preferably, a protective pad is fixedly connected to the lower surface of the protective plate, and the protective pad has a circular cross-section.

[0014] The effect achieved by the above components is that the protective pad can protect the protective plate and prevent the protective plate from excessive wear during use.

[0015] Preferably, a plurality of sliding rods are fixedly connected to the arc surface of the sleeve rod, and the plurality of sliding rods are evenly distributed on the sleeve rod, and the slip ring is slidably connected to the sliding rods.

[0016] The effect achieved by the above components is that the slide bar can limit the movement of the slip ring, preventing the slip ring from rotating with the sleeve bar when it moves.

[0017] Preferably, the fixing rod has a circular cross-section and is made of stainless steel.

[0018] The effect achieved by the above components is that the stainless steel material can increase the service life of the fixing rod and prevent the fixing rod from rusting during use.

[0019] Compared with related technologies, the electron beam anti-climb crucible provided by this utility model has the following beneficial effects:

[0020] This invention provides an electron beam anti-climbing crucible. Through the addition of an auxiliary structure, existing graphite crucibles, also known as copper melting pots or copper melting bags, are crucibles made from graphite, clay, silica, and wax stone. Graphite crucibles are mainly used for smelting non-ferrous metals and their alloys, such as copper, brass, gold, silver, zinc, and lead. High-purity graphite crucibles have characteristics such as low impurity content, high temperature resistance, oxidation resistance, and resistance to metal solution corrosion. However, when melting metals using electron beam equipment, high-energy impacts and non-wetting surfaces often cause liquid metal to climb out of the crucible and penetrate into the interior, leading to overall crucible damage and material waste. Furthermore, traditional crucibles, due to their open design, are easily contaminated by external factors. This device provides convenient protection for the crucible body. It allows for easy adjustment of the height of the protective plate as required, and the protective plate can be moved aside during material loading to avoid interfering with the loading process.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 4The auxiliary structure 3 includes a fixed rod 301, which is fixedly connected to the outer shell 1. A sleeve rod 304 is rotatably connected to the upper end of the fixed rod 301. A slip ring 305 is slidably connected to the arc surface of the sleeve rod 304. Several insert rods 307 are fixedly connected to the lower surface of the slip ring 305. A fixed ring 309 is fixedly connected to the arc surface of the fixed rod 301. Several insertion holes 308 are opened on the inner wall of the fixed ring 309. The insert rods 307 are adapted to the insertion holes 308. A screw rod 302 is slidably connected to the inner wall of the sleeve rod 304. A connecting rod 311 is fixedly connected to the upper end of the screw rod 302. A protective plate 303 is fixedly connected to the upper end of the connecting rod 311. A threaded ring 313 is rotatably connected to the upper end of the sleeve rod 304. The threaded ring 313 is threadedly connected to the screw rod 302. When protection of the crucible body 2 is required, the slip ring 305 is pulled to move, causing the insertion rod 307 to move. The slip ring 305 slides on the arc surface of the sleeve rod 304, then the insertion rod 307 is separated from the insertion hole 308 on the fixing ring 309. The slip ring 305 is rotated to move, causing the sleeve rod 304 to rotate at the upper end of the fixing rod 301. Then the sleeve rod 304 causes the screw 302 to move, which in turn causes the connecting rod 311 to move. The connecting rod 311 then causes the protective plate 303 to move, and the protective plate 303 is placed above the crucible body 2. Finally, the insertion rod 307 on the slip ring 305 is removed. Align the insertion rod 307 with the insertion hole 308 on the fixed ring 309, and then move the sliding ring 305 downwards. The sliding ring 305 drives the insertion rod 307 to be inserted into the insertion hole 308 for fixation. When it is necessary to adjust the height of the protective plate 303, rotate the threaded ring 313 to move it. The threaded ring 313 drives the screw 302 to move. The screw 302 slides on the inner wall of the sleeve rod 304. The screw 302 drives the connecting rod 311 to move it. The connecting rod 311 drives the protective plate 303 to move, thereby adjusting the height of the protective plate 303. The arc surface of the threaded ring 313 has several slots 314, which are evenly distributed on the threaded ring 313. The slots 314 can increase the friction between the hand and the threaded ring 313 and prevent slippage when rotating the threaded ring 313. The arc surface of the sliding ring 305 is fixedly connected to several handles 306, which are evenly distributed on the sliding ring 305. When it is necessary to move the slip ring 305, the lever 306 can be rotated directly. The lever 306 drives the slip ring 305 to move, making the movement of the ring more convenient. A protective pad 312 is fixedly connected to the lower surface of the protective plate 303. The protective pad 312 has a circular cross-section. The protective pad 312 can protect the protective plate 303 and prevent excessive wear during use. Several sliding rods 310 are fixedly connected to the arc surface of the sleeve rod 304. The sliding rods 310 are evenly distributed on the sleeve rod 304, and the slip ring 305 is slidably connected to the sliding rods 310.The slide rod 310 can limit the movement of the slip ring 305, preventing the slip ring 305 from rotating with the sleeve rod 304 during movement. The fixed rod 301 has a circular cross-section and is made of stainless steel. The stainless steel material increases the service life of the fixed rod 301 and prevents it from rusting during use.

[0030] The working principle of the electron beam anti-climb crucible provided by this utility model is as follows: When protection of the crucible body 2 is required, the slip ring 305 is pulled to move, and the slip ring 305 drives the insertion rod 307 to move. The slip ring 305 slides on the arc surface of the sleeve rod 304, and then the insertion rod 307 is separated from the insertion hole 308 on the fixing ring 309. The slip ring 305 is rotated to move, and the slip ring 305 drives the sleeve rod 304 to rotate at the upper end of the fixing rod 301. Then the sleeve rod 304... 04. The screw 302 is moved, which in turn moves the connecting rod 311. The connecting rod 311 then moves the protective plate 303. The protective plate 303 is then placed above the crucible body 2. The insert rod 307 on the slip ring 305 is aligned with the insertion hole 308 on the fixing ring 309. The slip ring 305 is then moved downwards, causing the insert rod 307 to be inserted into the insertion hole 308 for fixation. When the height of the protective plate 303 needs to be adjusted, the screw thread is rotated. The threaded ring 313 moves, driving the screw 302 to move. The screw 302 slides on the inner wall of the sleeve 304, driving the connecting rod 311 to move. The connecting rod 311 then drives the protective plate 303 to move, thereby adjusting the height of the protective plate 303. The groove 314 increases the friction between the hand and the threaded ring 313, preventing slippage when rotating the threaded ring 313. When it is necessary to move the slip ring 305, the handle 306 can be rotated directly, causing the slip ring 305 to move. The handle 306 makes moving the ring more convenient. The protective pad 312 protects the protective plate 303, preventing excessive wear during use.
