Abstract
Claims
1. A dustproof and cooling protection device for molten iron level gauges, characterized in that: Installed above the molten iron ladle, the device includes a radar level gauge. The radar level gauge is equipped with a dust cover, which has a nitrogen inlet and a nitrogen outlet to facilitate the circulation of gas inside the dust cover. The radar level gauge also includes a lower metal cylinder, which is connected to several purge air pipes that connect upwards to the inside of the dust cover.
2. The dustproof and cooling protection device for a molten iron level gauge according to claim 1, characterized in that: The metal cylinder includes a connecting flange at the upper end, and a radar level gauge and a dust cover are connected to the connecting flange.
3. The dustproof cooling protection device for a molten iron level gauge according to claim 2, characterized in that: The purging air pipe is connected between the outer periphery of the metal cylinder and the lower end face of the connecting flange, connecting the inside of the metal cylinder with the inside of the dust cover.
4. The dustproof cooling protection device for a molten iron level gauge according to claim 1, characterized in that: The metal cylinder is flared, with a smaller top and a larger bottom.
5. The dustproof cooling protection device for the molten iron level gauge according to claim 1 or 4, characterized in that: The lower end of the metal cylinder is also connected to a waveguide plate to focus the emitted wave on a set area.
6. The dustproof cooling protection device for a molten iron level gauge according to claim 1, characterized in that: The nitrogen inlet height is higher than the nitrogen outlet height.
7. The dustproof cooling protection device for a molten iron level gauge according to claim 1 or 6, characterized in that: The nitrogen outlet is located near the purge gas pipe.
8. The dustproof cooling protection device for a molten iron level gauge according to claim 1, characterized in that: The nitrogen inlet is equipped with a quick-connect straight connector, and the intake pipe can be detachably connected through the quick-connect straight connector.
