This utility model provides a furnace nose lifting device for continuous galvanizing production, including a furnace nose body, a mounting base, a dual-axis drive assembly, two opposing worm gear lifters, and two opposing tie rods. The two worm gear lifters are fixedly installed on both sides of the mounting base. The dual-axis drive assembly is installed on the top of the mounting base, and the output end of the dual-axis drive assembly is connected to the input end of the two worm gear lifters respectively. The output end of the two worm gear lifters is fixedly connected to the top of the two tie rods respectively. The bottom end of the two tie rods is fixedly connected to the outside of the furnace nose body. The two ends of the motor of this device are connected to the input ends of the two worm gear lifters respectively through cross-shaped universal joints. The dual-axis motor output ensures that the two worm gear lifters start simultaneously, avoiding the tilting of the furnace nose body due to insufficient power on one side. This device can expose the immersion section of the furnace nose to the zinc pot without stopping the production line, facilitating online replacement of the zinc pot.

This utility model discloses a timed cleaning device for a radar level gauge antenna in a dry distillation buffer silo. A desalination mechanism is installed on the radar level gauge's measuring connecting pipe. The outlet of the desalination mechanism's demineralized water flushing pipe passes through the radar level gauge's measuring connecting pipe. The demineralized water flushing pipe is equipped with a first shut-off valve, a first solenoid valve, and a second shut-off valve. The radar level gauge and the first solenoid valve are connected to a PLC. The desalination mechanism ensures that demineralized water can flush away coal dust and sludge from the radar level gauge antenna through the demineralized water flushing pipe. A nitrogen pipe and a first nitrogen purging pipe dry any residual water on the antenna. Third and fourth nitrogen purging pipes continuously blow air, maintaining positive pressure inside the first nitrogen purging pipe and the demineralized water flushing pipe to prevent coal dust backflow and blockage, and to prevent the timed flushing device from malfunctioning. Through timed cyclical purging, it is ensured that thick coal dust and sludge cannot accumulate on the radar level gauge antenna, allowing the radar level gauge to accurately measure the coal in the dry distillation buffer silo.
