Abstract

The invention provides a monitoring device and monitoring method for a distribution chute of a blast furnace, and belongs to the technical field of equipment monitoring. The monitoring device for thedistribution chute of the blast furnace comprises a wiping disc, a thermal imaging camera, a first drive mechanism, a second drive mechanism, and a controller, wherein the wiping disc stretches into asealing cover of the blast furnace from the outside and is rotationally connected with the sealing cover, a bypass hole is formed in the wiping disc, and a wiping cloth is arranged on the wiping disc; the thermal imaging camera is arranged in the bypass hole and capable of moving along the axis of the bypass hole; the first drive mechanism is used for driving the wiping disc to rotationally wipethe thermal imaging camera; the second drive mechanism is used for driving the thermal imaging camera to move; and the controller is used for controlling the first drive mechanism, the second drive mechanism and the thermal imaging camera. In the monitoring method for the distribution chute of the blast furnace, the distribution chute is monitored through the monitoring device for the distributionchute of the blast furnace. According to the monitoring device and monitoring method for the distribution chute of the blast furnace, the definition of images detected by the thermal imaging camera is ensured, and real-time monitoring for the distribution chute is realized.

Description

technical field [0001] The invention belongs to the technical field of equipment monitoring, and more specifically relates to a monitoring device and a monitoring method for a blast furnace distribution chute. Background technique [0002] The distribution chute is one of the key equipments of the ironmaking blast furnace, and it is responsible for the important task of directly distributing materials into the blast furnace. The distributing chute is located above the throat of the blast furnace and hangs directly below the airtight box on the top of the furnace. The distribution chute works at a high temperature, generally 80-300°C. [0003] In the blast furnace production, the most serious fault that destroys the nearly sinusoidal distribution of the charge is the chute falling off. In the blast furnace production, due to mechanical failure or production accidents, the distribution chute will break away from the gear box suspension mechanism and fall into the blast furnac...
