[0004] The technical solution to solve the technical problem is a casting plate flow trough aluminum liquid anti-bubbling structure, including a bracket, the two ends of the bracket are fixed on both sides of the casting plate flow trough, a ring is rotatably arranged in the middle of the bracket, an exhaust pipe is connected to the inner thread of the ring, the interior of the exhaust pipe is a cavity, a first spiral groove and a second spiral groove are respectively arranged on the inner and outer sides of the exhaust pipe, a through hole connected to the first spiral groove is arranged on the top of the exhaust pipe, and an exhaust pipe is passed through the exhaust pipe.

[0005] Preferably, rotating shafts rotatably connected to the bracket are provided on both sides of the collar, and ends of the rotating shafts are fixedly connected to the bracket via screws.

[0006] Preferably, the collar is provided with an internal thread, and the outside of the exhaust pipe is provided with an external thread.

[0007] Preferably, a cover plate is provided on the top of the exhaust pipe, a through hole is provided on the cover plate, and the exhaust pipe is threadedly connected to the cover plate.

[0008] The utility model has a simple and ingenious structure and is easy to use. An anti-bubble structure is arranged in the casting plate flow channel to eliminate air in the aluminum liquid and prevent the air from entering the crystallizer to affect the quality of the cast aluminum ingot.

[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 5 A casting plate flow trough aluminum liquid anti-bubbling structure is provided, comprising a bracket 1, two ends of the bracket 1 are fixed on both sides of the casting plate flow trough, a ring 2 is rotatably provided in the middle of the bracket 1, the inner thread 10 of the ring 2 is connected to an exhaust pipe 3, the exhaust pipe 3 has a cavity inside, and the exhaust pipe 3 is respectively provided with a first spiral groove 4 and a second spiral groove 5 on the inner and outer sides, a through hole 6 connected to the first spiral groove 4 is provided on the top of the exhaust pipe 3, and an exhaust pipe 7 is passed through the exhaust pipe 3.

[0016] When the utility model is used in a specific way,

[0017] Fix the bracket 1 on both sides of the casting plate flow channel so that the exhaust pipe 3 extends into the flow channel, adjust the angle and position of the exhaust pipe 3, when the aluminum liquid flows in the flow channel, if the aluminum liquid contains air, the air can be discharged upward along the first spiral groove 4 or the second spiral groove 5, so as to avoid air being trapped in the aluminum liquid and bubbling, and at the same time avoid air entering the crystallizer to affect the quality of the ingot.

[0018] The exhaust pipe 7 can extend into the bottom of the launder to extract the air at the bottom of the aluminum liquid.

[0019] Rotating shafts 8 rotatably connected to the bracket 1 are provided on both sides of the collar 2. The ends of the rotating shafts 8 are fixedly connected to the bracket 1 via screws 9, which are used to adjust the angle of the collar 2, that is, the angle of the exhaust pipe 3, so that the exhaust pipe 3 can be inserted into the aluminum liquid at a reasonable angle to discharge the air in the aluminum liquid without generating bubbles.

[0020] An internal thread 10 is provided inside the collar 2, an external thread 11 is provided on the outside of the exhaust pipe 3, a cover plate 12 is provided on the top of the exhaust pipe 3, a through hole 6 is provided on the cover plate 12, the exhaust pipe 7 is threadedly connected to the cover plate 12, the exhaust pipe 3 is threadedly connected to the collar 2, and the length of the exhaust pipe 3 extending into the flow channel can be adjusted to adapt to different types of casting discs. The threaded connection between the exhaust pipe 7 and the cover plate 12 is also used to adjust the position of the bottom of the exhaust pipe 7 to adapt to different types of casting discs.

[0021] The external thread 11 does not conflict with the second spiral groove 5 on the outside of the exhaust pipe 3, and the threaded connection between the exhaust pipe 3 and the collar 2 is not affected. At the same time, the second spiral groove 5 can be used for exhaust to prevent bubbling of aluminum liquid.

[0022] Compared with the prior art, the utility model has the following beneficial effects: an exhaust pipe is arranged in the casting plate flow channel to eliminate bubbles in the aluminum liquid without generating bubbles, thereby preventing bubbles from entering the crystallizer and affecting the quality of the aluminum ingot, thereby improving the product quality.
