Detailed Embodiments

[0018] Referring to Figures 1 to 4 As shown, the present utility model provides a liquid level detection device for molten iron pouring, including: a liquid level float 1 and a liquid level lifting platform 3. The upper end of the liquid level float 1 is connected to the liquid level lifting platform 3 through a lifting column 12 penetrating through.

[0019] The crucible cover 11 is sleeved and fixed on the column surface of the lifting column 12. The upper surface of the lifting column 12 is fixed with a limit top plate 13. The upper end of the limit top plate 13 is wound and connected with a winding and unwinding cylinder 32 through a rope 14. The winding and unwinding cylinder 32 is connected with the liquid level lifting platform 3 through a bracket 31. The front side of the liquid level lifting platform 3 is axially connected with a driving rotating plate 22 through a motor 34. The driving rotating plate 22 is connected with the protective crucible 2 through a clamping block 23.

[0020] When detecting the molten iron pouring liquid level, first place the liquid level float 1 in the molten iron pouring container. The liquid level float 1 is pushed up by the rising of the molten iron liquid level until the distance sensor 33 detects that the preset rising liquid level maximum value is reached. Then start the alarm and stop pouring continuously. After the detection is completed, wind up and pull up the liquid level float 1 through the winding and unwinding cylinder 32, rotate the protective crucible 2 to the lower part of the liquid level float 1, and the winding and unwinding cylinder 32 rotates in reverse to make the liquid level float 1 fall into the protective crucible 2. At the same time, the crucible cover 11 at the upper end of the liquid level float 1 falls and presses on the upper surface of the protective crucible 2 to prevent the molten iron droplets on the surface of the liquid level float 1 from dripping. Finally, move out the liquid level detection device.

[0021] In this embodiment, a detection base 4 is arranged on the lower end surface of the liquid level lifting platform 3. An electric push rod 42 is embedded and installed inside the detection base 4; and the electric push rod 42 is connected with the lower surface of the liquid level lifting platform 3. A control box 41 is installed on the outer side surface of the detection base 4. A bracket 31 is welded on the upper surface of the liquid level lifting platform 3; and the front end of the bracket 31 is axially connected with a winding and unwinding cylinder 32 through a small stepping motor.

[0022] As a preferred implementation manner, the electric push rod 42 is used to push the detection base 4 to move up and down, so that the detection base 4 is placed on the surface of the molten iron pouring container. The forward and reverse rotation of the winding and unwinding cylinder 32 drives the winding and unwinding of the wound rope 14, which is convenient for pulling up the liquid level float 1 after liquid level detection. It is convenient to move the protective crucible 2 to the lower end of the liquid level float 1, and it is convenient for the liquid level float 1 to fall into the protective crucible 2.

[0023] In this embodiment, a distance sensor 33 is embedded and installed on the upper surface of the liquid level lifting platform 3; and the distance sensor 33 is in contact with the limit top plate 13. An alarm is installed on the right side surface of the liquid level lifting platform 3. A motor 34 is embedded and fixed inside the liquid level lifting platform 3; and the driving rotating plate 22 is attached to the front end surface of the liquid level lifting platform 3.

[0024] As a preferred implementation manner, the distance sensor 33 is used to sense the rising height of the limit top plate 13. The rising height of the limit top plate 13 is equal to the rising height of the liquid level float 1 by the molten iron, which is convenient for detecting the liquid level of the molten iron during pouring and avoiding the overflow of the molten iron. The alarm is convenient for prompting the pouring staff to stop the pouring work.

[0025] In this embodiment, clamping blocks 23 are welded to both sides of the lower end of the driving rotating plate 22, and the clamping blocks 23 are fixed to the protective crucible 2 through positioning studs 21.

[0026] As a preferred implementation, the positioning studs 21 at the clamping blocks 23 are taken out, and the protective crucible 2 is lifted to facilitate the separation of the driving rotating plate 22 from the protective crucible 2, which is convenient for cleaning the molten iron in the protective crucible 2.

[0027] In this embodiment, the protective crucible 2, the driving rotating plate 22 and the motor 34 form a receiving and loading structure for the liquid level float 1; and the protective crucible 2 rotates to a position above the side of the liquid level float 1.

[0028] As a preferred implementation, the receiving and loading structure of the liquid level float 1 is convenient for loading the liquid level float 1 taken out from the molten iron, avoiding the molten iron attached to the surface of the liquid level float 1 from falling into the external environment, and preventing the pouring personnel from being scalded by the high-temperature dripping molten iron.

[0029] The molten iron pouring liquid level detection device of the present utility model can effectively solve the problem in the prior art that the molten iron adhered to the surface of the floating ball moved to the outside is likely to drip on the ground and is difficult to clean. It is convenient for loading the liquid level float taken out from the molten iron, avoiding the molten iron attached to the surface of the liquid level float from falling into the external environment, preventing the pouring personnel from being scalded by the high-temperature dripping molten iron, improving the safety protection effect of the molten iron liquid level detection device, and is applicable to the molten iron pouring liquid level detection device.
