AI Technical Summary
The water level monitoring device of the slag removal machine is inaccurate or damaged due to alkaline scaling, making it unable to accurately monitor the water level in the tank. Existing technology cannot prevent the measuring points from coming into contact with corrosive water, causing the alarm device to fail.
A low water level alarm device for a wet slag remover is designed. It adopts a floating mechanism and a contact separation design. By welding steel beams and hollow steel pipes to the furnace head of the slag remover, the buoyancy mechanism avoids the measuring point from contacting corrosive water. The alarm is triggered by mechanical contacts, which is resistant to electromagnetic interference. The overall structure is suspended for easy maintenance.
It enables accurate monitoring of water levels, avoids corrosion of measuring points, improves the reliability and anti-interference ability of alarm devices, and eliminates the need to shut down the slag removal machine for maintenance.

Abstract
Claims
1. A low water level alarm device for a wet slag remover, characterized in that, The device includes a steel beam horizontally fixed to the furnace at the head of the slag remover. A ring is welded to the end of the steel beam, and a hollow steel pipe is vertically inserted into the ring. A hollow box is sealed to the bottom of the hollow steel pipe, and the hollow box provides buoyancy so that the hollow steel pipe rises and falls with the water surface. A first steel needle is fixed to the upper part of the hollow steel pipe, and a second steel needle is provided at the position directly below the first steel needle. The second steel needle is connected to an alarm through a wire.
2. The low water level alarm device for a wet type slag conveyor water seal according to claim 1, characterized by, The hollow box is a sealed structure, and its top is welded and fixed to the bottom of the hollow steel pipe.
3. The low water level alarm device for a wet type slag conveyor water seal according to claim 1, characterized by, The hollow steel pipe passes through the ring and is fitted with it with a gap. The ring restricts the horizontal displacement of the hollow steel pipe and provides vertical guidance.
4. The low water level alarm device for a wet type slag conveyor water seal according to claim 1, characterized by The first steel needle is horizontally welded to the outer wall of the hollow steel pipe, and the second steel needle is fixed on an independent bracket and is vertically aligned with the first steel needle.
5. The low water level alarm device for a wet type slag conveyor water seal according to claim 1, characterized by, The second steel needle is connected to the low-level alarm module of the slag removal machine control system via an insulated wire.
6. The low water level alarm device for a wet type slag conveyor water seal according to claim 1, characterized by The inner diameter of the ring is 1-5 mm larger than the outer diameter of the hollow steel pipe.
7. The low water level alarm device for a wet type slag conveyor water seal according to claim 1, characterized by The steel beam is fixed to the outer wall of the furnace by welding, and its extension direction is parallel to the water surface of the slag remover's sealing water tank.
8. The low water level alarm device for a wet type slag conveyor water seal according to claim 1, characterized by The low water level alarm is triggered when the tip of the first steel needle comes into contact with the tip of the second steel needle.
9. The low water level alarm device for a wet type slag conveyor water seal according to claim 2, characterized by The connection between the hollow box and the hollow steel pipe is achieved by continuous sealing welding.
10. The low water level alarm device for a wet type slag conveyor water seal according to claim 1, characterized by The installation height of the second steel needle is 20-50mm higher than the lowest water level line of the sealing water tank of the slag remover.
