Detailed Description
In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, and the utility model is further explained below.
As shown in the figures 1-3, the front box aluminum liquid level two-stage flow control device comprises a flow control box and a flow groove 3 which are arranged between a filter box 1 and a front box 5, wherein the flow control box is divided into a first flow control box 2 and a second flow control box 4, and the filter box 1, the first flow control box 2, the second flow control box 4 and the front box 5 are sequentially connected through the flow groove 3.
The first flow control box 2 and the second flow control box 4 both comprise a feeding hole 17, a discharging hole 18, a discharging hole 6 and a flow control device, and the flow control device is arranged above the first flow control box 2 and the second flow control box 4.
The flow control device comprises a float 7, the center of the float 7 is connected with a connecting rod 10, the other end of the connecting rod 10 extends out of a flow control support 8, the connecting rod 10 is connected with the flow control support 8 in a sliding mode, an opening through which the connecting rod 10 penetrates is formed in the flow control support 8, the opening of the flow control support 8 is larger than the width of the connecting rod 10, and therefore the influence of friction force on the float is fully reduced.
One end of the connecting rod 10 extending out of the flow control support 8 is provided with a roller 11, the roller 11 is connected with the connecting rod 10 through a rotating shaft, and the roller 11 is rotatably connected with the rotating shaft. The lower end of the roller 11 is wound with a chain 12, one end of the chain 12 is fixed on the fixed rod 9, and the fixed rod 9 is fixed on the flow control bracket 8. The other end of the chain 12 bypasses the fixed wheel 13 and is fixed on the gate 16, the fixed wheel 13 is fixed on the flow control bracket 8 through the bracket, and the fixed wheel 13 is rotatably connected with the bracket. The first flow control box 2 and the second flow control box 4 are both provided with a limiting hole 14 for the gate 16 to enter and exit, and the gate 16 is positioned in the limiting hole 14. The inner side of the limiting hole 14 is provided with 2 rows of ball belts 15. The roller 11, the fixed wheel 13 and the ball belt 15 are adopted, so that the influence of friction on the device is reduced, and the linkage effect between the buoy 7 and the gate 16 is improved.
The upper end of the connecting rod 10 is provided with a slideway, the position of the roller 11 can be adjusted, the rotating shaft of the roller 11 is inserted into the slideway, and the width of the slideway is slightly larger than the diameter of the rotating shaft, so that the rotating shaft can slide in the slideway. Nuts are provided on the rotating shaft at both sides of the connecting rod 10, and the rotating shaft is fixed to the connecting rod 10 by tightening the nuts, thereby fixing the roller 11. The height of the roller 11 can be adjusted as required by the slide way.
Before production begins, the position of the roller 11 is adjusted according to the required liquid level height of the molten aluminum in the front box 5.
In the production process, when the liquid level of the aluminum liquid in the first flow control box 2 is lower than that of the aluminum liquid in the launder 3, the float 7 gradually rises along with the flow of the aluminum liquid into the first flow control box 2, the corresponding roller 11 also rises, and then the gate 16 gradually descends, so that the amount of the aluminum liquid flowing into the first flow control box 2 is reduced. When the liquid level heights of the aluminum liquid in the first flow control box 2 and the flow groove 3 are consistent, the positions of the float 7 and the gate 16 are not changed, and dynamic balance is achieved. Similarly, the second flow control box 4 works in the same way as the first flow control box 2.
