Blanking chute and chute device capable of automatically detecting and dredging blockage

Abstract

The invention provides a blanking chute and a chute device capable of automatically detecting and dredging blockage. Through the cooperation of an ultrasonic detector, a dredging device and a blanking chute control system, an acoustic wave diagram fed back by the blanking chute and detected by the ultrasonic detector is compared with an acoustic wave diagram preset by the blanking chute control system, so that the blanking chute control system sends an instruction of starting / stopping the dredging device and an instruction of closing / opening a flap gate, and the blanking process is guided. The blanking chute and the chute device have the advantages of being simple in structure and capable of achieving remote monitoring and automatic operation, the probability that the blanking chute is blocked can be reduced, the labor intensity of operators is reduced, and more time is gained for production.

Description

technical field [0001] The application relates to the technical field of metallurgical equipment, in particular to a feeding chute and a feeding device for automatically detecting and unclogging blockages. Background technique [0002] The refining furnace often needs to add various materials during the smelting process, usually through the form of a slide pipe from the opening of the furnace cover into the furnace, but when the slide is not needed, the slide pipe channel must be closed to prevent the flue gas from overflowing, causing The heat loss in the furnace and the air pollution in the workshop will deteriorate the working environment, or the outside air will enter the furnace from the slide pipe channel, which will accelerate the electrode oxidation and increase the workload of the subsequent dust removal equipment. [0003] In the prior art, a flap gate is used to open and close the blanking chute. The discharge chute is installed under the flap gate. When the flap...

AI Technical Summary

Problems solved by technology

The discharge chute is installed under the flap gate. When the flap gate is opened, the pre-stored bulk material in the hopper enters the ladle through the discharge chute. The discharge chute is in an inclined installation state. When the flap gate opens, the speed When it is too fast, the bulk material suddenly pours into the discharge chute, causing the chute to be blocked

Because the discharge chute is a closed type chute, and the installation location is far away from the operating room, there is no equipment to monitor the discharge status of the discharge chute, so it is difficult to find the blockage of the discharge chute. When the blockage is found, it is usually seriously blocked. takes a lot of time to process
