The utility model relates to an instant monitoring device, in particular to an ultrasonic ultrasonic monitoring device for a wall thickness of a high temperature furnace.

The high-temperature furnace is constructed of refractory bricks and then coated with a furnace shell made of sheet metal to strengthen the furnace structure. When the furnace is built, a metal rod is pre-buried so that one end is located in the furnace body to exhibit refractory wear and the other end is exposed. The length is measured ultrasonically outside the furnace. That is, when the inner surface of the furnace wall is thinned by erosion, corrosion, etc., the metal rod is also shortened at the same time, and then the length is measured by ultrasonic waves on one end of the metal rod outside the furnace body to understand the wall change. The extent of thinness.

However, the above measurement method is not instantaneous, and it is impossible to issue a warning when the thickness of the furnace wall is close to the lower limit value, which may cause damage to the work safety or affect the operation of the production line.

Therefore, the purpose of the present invention is to provide an ultra-sonic ultrasonic monitoring device for a high-temperature furnace wall thickness with an instant monitoring function.

Therefore, the novel high-temperature furnace wall thickness ultrasonic ultrasonic monitoring device is installed on a high-temperature melting furnace, the high-temperature melting furnace comprises a furnace wall, and the ultrasonic instantaneous monitoring device comprises a joint fixed to the furnace wall, An adapter, a transducer disposed on the adapter, a connector disposed at the other end of the transducer, a coupling to the adapter and covering the adapter, the transducer And a housing unit of the connector, and a wire disposed through the housing unit and electrically connected to the transducer.

The joint includes a substrate fixed to the furnace wall of the high-temperature furnace, a metal rod embedded in the furnace wall and having one end penetrating the furnace wall and passing through the substrate, and a convexity of the substrate a joint that surrounds and surrounds the metal rod. The adapter is fixed to one end of the metal rod passing through the substrate.

The transducer has a crystal end and a fixed end opposite to the crystal end. The transducer is disposed on the adapter and rotatable relative to the adapter, and the crystal end faces the metal rod. The connecting seat is disposed on the fixed end of the transducer, and the connecting seat defines a through hole along the axial direction thereof. The outer casing unit is coupled to the joint of the joint, and the wire is threaded through the outer casing unit and electrically connected to the transducer through the through hole of the joint.

The effect of the novel is that through the above structural design, not only has the function of instantly monitoring the thickness of the furnace wall, but also the position between the crystal end of the transducer and the metal rod can be easily adjusted to obtain the best signal echo. Improve the correctness of monitoring.
