Description

Technical Field

[0001] The utility model relates to the technical field of hot dip galvanizing. Background Art

[0002] The continuous hot dip galvanizing production line of strip steel completes the galvanizing process by immersing the strip steel into the molten zinc bath. The zinc pot is one of the most important equipment on the production line, and its function is to melt zinc ingots and form a zinc liquid pool. The zinc pot liquid level is a core quality control point on the continuous hot dip galvanizing production line. If the detection of the zinc pot liquid level is unstable and the zinc pot liquid level is out of control, the zinc slag in the furnace nose and the zinc pot will adhere to the strip steel along with the liquid level fluctuation, resulting in quality defects. Therefore, the accuracy of zinc pot liquid level measurement and the stability of control are crucial for improving the surface quality of strip steel.

[0003] The traditional zinc pot liquid level measurement system has the following problems: ① The measurement accuracy of the liquid level gauge is not high, and it is unable to accurately detect the minute changes in the zinc pot liquid level. ② Affected by the zinc slag at the liquid level measurement point, the measured liquid level value will fluctuate abnormally by a large margin within a short period of time. ③ During the slag skimming operation, the removal of zinc slag causes a large drop in the zinc pot liquid level, and the interference with the zinc pot liquid level measurement point during slag skimming will also cause abnormal liquid level fluctuations. Summary of the Utility Model

[0004] In order to overcome the above problems existing in the traditional zinc pot liquid level measurement system, the utility model provides a zinc pot liquid level measurement device.

[0005] The technical solution adopted by the utility model to achieve the above purpose is: a zinc pot liquid level measurement device, in which a liquid level protection ring 2 is fixedly arranged in the zinc pot 1, a floating buoy 9 is arranged inside the liquid level protection ring 2, and a laser rangefinder 3 is arranged directly above the floating buoy 9.

[0006] A touch arm 8 is installed on the outer edge of the floating buoy 9.

[0007] A column 6 is installed on the ground 7 outside the zinc pot 1, the liquid level protection ring 2 is installed on the column 6 through a protection ring fixing plate 5, and the laser rangefinder 3 is installed on the column 6 through a laser rangefinder fixing plate 4.

[0008] The zinc pot liquid level measurement device of the utility model can avoid the disturbance of abnormal factors such as the existence of zinc slag on the zinc liquid surface and daily slag skimming operations on the accuracy of zinc pot liquid level measurement, and realize accurate measurement of the zinc pot liquid level.

[0013] The zinc pot liquid level measuring device of the present utility model is as Figures 1 - 3 shown. The liquid level protection device includes a liquid level protection ring 7 and a liquid level floating buoy 8, and the liquid level measuring device is a laser rangefinder. The liquid level protection ring 2 and the laser rangefinder 3 are installed on the column 6 through the protection ring fixing plate 5 and the laser rangefinder fixing plate 4, and the laser rangefinder 3 is directly above the floating buoy 9.

[0014] Working principle: The liquid level floating buoy 9 floats on the zinc pot liquid surface inside the liquid level protection ring 2, and the laser rangefinder 3 measures the position of the liquid level floating buoy 9 to realize the measurement of the liquid level of the zinc pot 1. The liquid level protection ring 2 can isolate the liquid level disturbance generated during the operation of other positions of the zinc pot 1, and at the same time can also avoid the problem that the zinc slag at other positions moves to the liquid level measurement position to interfere with the measurement result. The liquid level floating buoy 9 is installed with a touch arm 8 so that the liquid level floating buoy 9 is always located at the center of the liquid level protection ring 2, and the liquid level floating buoy 9 keeps a certain distance from the liquid level protection ring 2 to avoid the zinc slag on the zinc liquid surface bonding the liquid level floating buoy 9 to the inner wall of the liquid level protection ring 7 during long-term use. Avoid abnormal factors such as the existence of zinc slag on the zinc liquid surface and daily slag fishing operations disturbing the accuracy of zinc pot liquid level measurement, and realize accurate measurement of the zinc pot liquid level.
