Description
Technical Field
[0001] The utility model relates to the technical field of vacuum furnaces, in particular to equipment for no-drop dark-flow casting used in vacuum furnaces. Background Art
[0002] No-drop underflow casting is a special casting method, also known as no-drop continuous casting. It uses the inertia and gravity of the fluid to maintain a continuous, stable and uninterrupted flow state during the casting filling process to achieve high-quality casting.
[0003] Patent No. 202122229713.3 proposes a device for zero-drop dark flow casting for a vacuum furnace, wherein a graphite crucible is placed in the cylindrical furnace body of the vacuum medium frequency melting furnace, and a crucible upper edge is provided at the upper end of the graphite crucible. A vertical through-notch is provided on the crucible upper edge to form a liquid flow channel, and the liquid flow channel is connected to an aluminum chute, a vacuum baffle valve, a rotating chute and a fixed chute in sequence; when pouring the aluminum melt, the vacuum medium frequency melting furnace body is tilted, and the aluminum melt in the graphite crucible flows out through the liquid flow channel, and then flows through the casting assembly until the crystallizer completes the zero-drop casting, thereby avoiding the involvement of gas and slag caused by the drop and disturbance of the melt, and finally realizing the preparation of high-quality and high-purity aluminum products with low gas and low slag.
[0004] However, it was found during the use of the above-mentioned equipment that the furnace body is tilted by the rotating shaft, but the liquid flow channel of the furnace body is on the same horizontal plane as the rotating shaft, so that the liquid flow channel always remains horizontal when the furnace body rotates. Therefore, during the casting process, the speed of the liquid in the furnace body passing through the liquid flow channel is relatively slow, which affects the subsequent processing efficiency.

DETAILED DESCRIPTION
[0021] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model. Example
[0022] like Figure 1 and Figure 4 As shown: a device for no-drop dark flow casting for a vacuum furnace, comprising a base 1, a side of a casting device 2 is arranged on one side of the top of the base 1, a liquid inlet pipe 3 is arranged on the casting device 2, a liquid flows into the casting device 2 through the liquid inlet pipe 3, and the liquid flows are processed by the casting device 2, a chute 11 is arranged in the middle of the top of the base 1, a driving motor 12 is arranged inside the base 1, an output end of the driving motor 12 is connected to a threaded rod 13, the threaded rod 13 passes through a slider 14, and the slider 14 is arranged in the chute 11;
[0023] The driving motor 12 is used to drive the threaded rod 13 connected to the driving motor 12 to rotate, so that the slider 14 on the threaded rod 13 can stand in the slide groove 11 and move along the slide groove 11. One end of the connecting rod 7 is rotatably connected to the slider 14, and the other end of the connecting rod 7 is connected to the connecting arm 63. The connecting arm 63 is arranged in the middle of the bottom of the adjustment seat 6. The movement of the slider 14 causes the angle between the connecting rod 7 and the base 1 to change, so that the height of the adjustment seat 6 can be changed by the rotation of the connecting rod 7.
[0024] like Figures 1 to 3 As shown, the adjustment seat 6 is arranged on the top of the base 1, and the adjustment seat 6 is arranged on one side of the liquid inlet pipe 3. The top and left sides of the adjustment seat 6 are both provided with connecting plates 61, and the furnace body 5 is arranged inside the connecting plate 61. The left and right sides of the furnace body 5 are both provided with rotating shafts 62. The connecting pipe 4 is arranged in the middle of the rotating shaft 62 on the side of the furnace body 5 close to the liquid inlet pipe 3, and the rotating shaft 62 on the side of the furnace body 5 away from the liquid inlet pipe 3 is connected to one side of the connecting plate 61;
[0025] A driving device is provided inside the adjusting seat 6, and the driving device is connected to the rotating shaft 62. The driving device drives the rotating shaft 62 to rotate, so that the rotating shaft 62 drives the furnace body 5 to rotate, so that the furnace body 5 tilts. When the furnace body 5 tilts, the rotating shaft 62 on the side of the furnace body 5 close to the liquid inlet pipe 3 rotates around the connecting pipe 4.
[0026] The connecting tube 4 passes through the connecting plate 61 close to the side of the liquid inlet pipe 3, and the connecting tube 4 is connected to the liquid inlet pipe 3. The connecting tube 4 can rotate around the liquid inlet pipe 3. The connecting tube 4 and the liquid inlet pipe 3 can be made of high-temperature resistant materials such as refractory ceramics or refractory graphite. The connection between the connecting tube 4 and the liquid inlet pipe 3 is sealed, and the connecting tube 4 is bent at a right angle.
[0027] A crucible 52 is provided inside the furnace body 5. The crucible 52 is used as a container for material smelting. A liquid flow groove 51 is provided above the inner wall of the crucible 52. When the furnace body 5 is rotated by the rotation of the rotating shaft 62, the crucible 52 inside the furnace body 5 is driven to rotate and tilt, so that the liquid after smelting in the crucible 52 is affected by the tilt and flows into the liquid flow groove 51.
[0028] The connecting tube 4 passes through the rotating shaft 62 and is connected to the liquid flow groove 51. When the driving motor 12 drives the adjusting seat 6 to change its height, the adjusting seat 6 and the connecting tube 4 are connected to the liquid inlet pipe 3, so that the angle of the connecting tube 4 changes and tilts, so that the liquid in the liquid flow groove 51 can quickly pass through the connecting tube 4 and enter the liquid inlet pipe 3.
[0029] A vacuum valve 8 is provided on the connecting pipe 4. When smelting is carried out in the crucible 52, the vacuum valve 8 is closed to maintain a vacuum environment. When liquid casting is carried out after smelting, the vacuum valve 8 is opened to allow the fluid to flow into the liquid inlet pipe 3. During the casting process, the liquid flows into the connecting pipe 4 through the liquid flow trough 51, enters the liquid inlet pipe 3 through the connecting pipe 4, and then flows into the casting device 2 for subsequent processing. During the flow process, the inertia and gravity of the fluid are utilized through the pipeline connection, and a continuous, stable and uninterrupted flow state is maintained during the casting filling process to achieve high-quality casting.
