The weighing scale is used for coarse liquid level detection. At this time, the capacitive liquid level sensor is in the off state. When the raw material liquid level drops to a specified value close to the alarm value, the weighing scale sends a signal to the controller. The controller starts the capacitive liquid level sensor and changes from coarse detection mode to precise detection mode. The detection accuracy is high when the liquid level is close to the alarm value. Since the capacitive liquid level sensor is not started in the early stage, the overall actual service life is long.

The liquid level accuracy is closer to the actual level, avoiding the raw material on the side wall being included in the calculation when converting the liquid level by weighing scale, thus improving safety. It is effective for raw materials with high viscosity.

[0018] (3) The lower end of the scale rod is fixedly connected to the annular scraper assembly through the connecting plate, which ensures more precise control.

[0019] (4) The upper end of the buffer spring is detachably connected to the positioning ring, and the lower end of the buffer spring is detachably connected to the sliding ring. The positioning effect is good, and it plays an elastic buffering role when scraping up and down.

[0020] (5) The lower end of nut two fits against the upper end of nut one, and the double nuts have a good anti-slip effect;

[0021] (6) The outer side of the cylindrical scraper is in contact with the inner side of the tank body. The inner diameter of the lower end of the arc-shaped feeder is smaller than the inner diameter of the upper end of the arc-shaped feeder. The raw material scraped from the cylindrical scraper is guided down by the arc-shaped feeder to avoid secondary contact with the inner side of the tank body. Attached Figure Description
