[0026] The utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figure 1-Figure 5 As shown, a casting and rolling mill flow trough liquid level stabilizing device comprises a guide trough 4, and also comprises an adjusting mechanism 3 for adjusting the height of the liquid level of the casting and rolling mill flow trough, and a flow stabilizing mechanism 2 for reducing the ripples of the liquid level of the flow trough is arranged on the adjusting mechanism 3;

[0028] In this embodiment: the flow stabilizing mechanism 2 includes a support frame 25, on which a flow stabilizing frame 21 is rotatably connected, a push shaft 22 is fixed at one end of the flow stabilizing frame 21, a limit frame 23 is fixed on the upper side of the flow stabilizing frame 21, and flow stabilizing hydraulic rods 24 are respectively fixed at the front and rear ends of the push shaft 22, and the lower end of the support frame 25 is fixed to the front and rear sides of the guide groove 4, and fixed columns are fixed at the front and rear sides of the flow stabilizing frame 21. Positioning columns for supporting the flow stabilizing hydraulic rod 24 are fixed at the front and rear sides of the guide groove 4. A tilting mechanism 1 is provided at one end of the flow stabilizing frame 21 close to the limit frame 23, and the telescopic part of the flow stabilizing hydraulic rod 24 is used to push one end of the flow stabilizing frame 21 to flip upward with the support frame 25 as the fulcrum, and then the adjustment mechanism 3 is pulled through the fixed column of the flow stabilizing frame 21 to act;

[0029] In this embodiment: the regulating mechanism 3 includes a connecting frame 31, the lower end of the connecting frame 31 is rotatably connected to a connecting seat 32, one end of the connecting seat 32 is fixed with a conical seat 33, a T-frame 34 is fixed above the connecting seat 32, one end of the conical seat 33 is located at the end of the buffer tank 5, and the buffer tank 5 is located at the position of the conical seat 33 and is provided with a conical hole matching with it. The upper end of the connecting frame 31 is rotatably connected to the fixed column of the flow stabilizing frame 21, and the connecting frame 31 is used to drive the connecting seat 32 to move away from the buffer tank 5, and the connecting seat 32 drives the T-frame 34 to break away from the blockage of the conical hole of the buffer tank 5, thereby controlling the flow rate of the aluminum liquid from the buffer tank 5 to the guide groove 4.

[0030] In this embodiment: the tilting mechanism 1 includes a tilting plate 11, a turning frame 12 and a bracket 13 are fixed to one side of the tilting plate 11, the bracket 13 is located above the turning frame 12, the telescopic part of the pushing hydraulic rod 14 is rotatably connected to the upper end of the turning frame 12, the upper end of the bracket 13 is rotatably connected to the other end of the flow stabilizing frame 21, and the fixed part of the pushing hydraulic rod 14 is rotatably connected to the limit frame 23. The turning of the flow stabilizing frame 21 is used to send the tilting plate 11 into the guide groove 4 through the bracket 13 and the turning frame 12, and then the tilting plate 11 is used to scrape the surface of the aluminum liquid to prevent the aluminum liquid from having ripples on the surface, and at the same time, the telescopic part of the pushing hydraulic rod 14 is used to push the tilting plate 11 through the turning frame 12 to adjust the inclination.

[0031] Working principle: when in use, first, the molten aluminum liquid enters the buffer pool 5, and the telescopic part of the flow stabilizing hydraulic rod 24 pushes the flow stabilizing frame 21 to flip upward with the support frame 25 as the fulcrum through the push shaft 22, and then the other end of the flow stabilizing frame 21 drives the inclined plate 11 to flip into the guide groove 4 through the bracket 13. At the same time, when the flow stabilizing frame 21 flips, the connecting seat 32 is driven by the connecting frame 31 to pull the conical seat 33 out of the conical hole of the buffer pool 5. In addition, when the connecting seat 32 drives the conical seat 33 to move, it slides on the guide groove 4 through the T-shaped frame 34, so as to prevent the conical seat 33 from being offset after being separated from the conical hole of the buffer pool 5. Then, the aluminum liquid in the buffer pool 5 enters the guide groove 4 through the conical hole of the buffer pool 5. At this time, the telescopic part of the push hydraulic rod 14 can be extended or shortened to push the flip frame 12 to make the inclined plate 11 flip around the bracket 13 as the center, so as to change the liquid level position of the lower end of the inclined plate 11 contacting the aluminum liquid in the guide groove 4;

[0032] When the liquid level in the guide groove 4 rises, the flow stabilizing frame 21 is driven to flip downward by the flow stabilizing hydraulic rod 24, so that the connecting frame 31 pushes the connecting seat 32 and the conical seat 33 to be inserted into the conical hole of the buffer tank 5, thereby changing the flow rate of the aluminum liquid entering the guide groove 4. At the same time, the hydraulic rod 14 is pushed to flip the inclined plate 11 downward through the flip frame 12, thereby ensuring that the water ripples generated by the rising liquid level at this time hit the inclined plate 11, thereby reducing the water ripples on the surface of the aluminum liquid.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
