Description

Technical Field

[0001] The invention relates to the technical field of aluminum liquid monitoring alarm devices, and in particular to a liquid leakage monitoring alarm device for aluminum alloy round ingot casting. Background Art

[0002] When producing aluminum alloy round ingots, it is particularly important to use a crystallizer for casting. Generally, dozens of bars are cast at a time, and sometimes more than a hundred bars.

[0003] At present, the existing technology of aluminum liquid leakage monitoring relies on manual observation of the flow changes on the surface of the aluminum liquid to determine whether there is a leakage. If dozens of bars are cast, manual repeated observation is required. This monitoring method is relatively cumbersome. Moreover, when dozens of bars are formed at the same time, if the crystallizer at the rear leaks, it is too late when the manual staff repeatedly walks to the rear in turn. It is difficult to be familiar with the leakage of aluminum liquid in the first time. At the same time, if dozens of bars are formed at the same time and the front and rear leak at the same time, it is difficult for the operator to determine which crystallizer is leaking in the first time, and then cannot adjust the leakage in the first time.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing leakage monitoring and alarm devices for aluminum alloy round ingot casting on the market, and even if they can be solved, they need to be solved through external tools, which cannot achieve the desired effect.

Through the setting of the elastic support member 36, the position of the sealing rope 35 is supported, thereby ensuring that the position of the sealing rope 35 will not shake.

[0049] The specific implementation of this embodiment is as follows: insert the blocking rope 35 into the interior of multiple elastic support members 36 and pass the two ends of the blocking rope 35 into the interior of the slot 39, then rotate the rotating plate 37, and the rotation of the rotating plate 37 drives the positioning screw 38 to rotate, and the positioning screw 38 is threadedly connected with the rotating disk 33 to move toward the surface of the blocking rope 35, and the movement of the positioning screw 38 drives the clamping plate 310 to move, and the blocking rope 35 is fastened to the interior of the slot 39 through the clamping plate 310, and when the above-mentioned reset seat 2210 moves, it drives the touch block 2206 to move, and when the touch block 2206 contacts the touch switch 2209, the touch switch 2209 receives the signal and transmits it to the external PLC control In the controller, the servo motor 32 is controlled by an external PLC controller to work, and the work of the servo motor 32 drives the rotating disk 33 to rotate, and the rotation of the rotating disk 33 drives the sealing rope 35 to be wound. At this time, the sealing rope 35 is forced to detach from the inside of the elastic support 36 and is placed inside the sealing groove 18. When the sealing rope 35 is wound into a twisted state, the sealing rope 35 on one side will pull the sealing block 34 to move, and the other side of the sealing block 34 will fit the position of the sealing rope 35 on the other side, and then the intersection of the sealing rope 35 is blocked by the sealing block 34. At the same time, the sealing rope 35 is tightly fitted to the inside of the sealing groove 18 for temporary blocking, so as to avoid a large amount of aluminum liquid leakage caused by unknown reasons at the first time.
