Detailed Description
The utility model provides a but early warning type air brick of visual monitoring safety height, includes air brick core 10, air brick seat 11, air brick core casing 12, and air brick core 10 and 11 sizes of air brick seat and shape are mutually supported, its characterized in that: the air brick core 10 is in a wedge-shaped structure with a narrow top and a wide bottom along the direction of the steel ladle, the bottom of the air brick core is provided with an air inlet tail pipe 13, and the air brick core 10 is wrapped by an air brick core shell 12 except for the upper surface and the lower surface of the air brick core and the communication surface of the air inlet tail pipe; the air brick core shell 12 is provided with 9 contact points along the longitudinal direction and is uniformly distributed at intervals in the height direction, each contact point is communicated with one end of a corresponding conducting wire 1, 2, 3, 4, 5, 6, 7, 8 and 9, the other end of each conducting wire is sequentially connected with indicator lamps 17, 18, 19, 20, 21, 22, 23, 24 and 25 in parallel, the other end of the parallel connection is connected with one end of a power supply 14, and the other end of the power supply 14 is connected with the outer wall of an air inlet tail pipe 13 through a conducting wire to form 9 parallel circuits corresponding to the 9 contact points; the outer wall of the inlet tail pipe and the air brick core shell 12 are both made of conductive materials, and the outer wall of the inlet tail pipe 13 is tightly connected with the bottom of the air brick core 10. The air inlet tail pipe (13) and the air brick core shell (12) are made of stainless steel.
The working principle and the working process of the patent are as follows: after the air brick is gradually eroded, the leads 1-9 are sequentially eroded to interrupt the circuit, so that the indicator lights 17-25 are sequentially extinguished, the gradual reduction of the total height of the air brick can be visually monitored, and the monitoring precision depends on the number of the leads and the spacing height. Therefore, the worker who replaces the air brick can judge whether to replace the air brick more easily and accurately.
As shown in fig. 2, the preferred embodiment of this patent is that molten steel erodes over the lead wire 1, the molten steel erosion interrupts the electrical circuit, causing the indicator light 17 to go out, and 9/10 indicating the safe height of the gas permeable brick remaining in total height can be visually displayed in a row of indicator lights.
