Automatic-cleaning converter blowing sound acquisition device

Abstract

The invention relates to the technical field of steelmaking and smelting sound acquisition, in particular to a sound acquisition device capable of automatically clearing ash and timely cooling. The sound acquisition device comprises a shell and is characterized in that the shell is of a long-cylinder T-shaped structure, the outer layer of the shell is coated with a cooling device, and a mounting base is fixedly arranged at the bottom layer inside the shell; and the mounting base is provided with a printed circuit board, a driving motor penetrates through the center of the mounting base and isfixed to the bottom of the shell, the driving motor is in driving connection with a spiral ash remover, a nitrogen purging pipe penetrates through a through hole in the lower position of the center ofthe mounting base to be fixedly inserted into the bottom of the shell, and a sound acquisition sensor, a micro camera and a temperature sensor are further arranged on the mounting base. The sound acquisition device capable of automatically clearing the ash and timely cooling has the beneficial effects that the daily maintenance-free of the sound acquisition device can be realized, the clearing and sweeping of suspended dust and large-particle-size slag and the over-high temperature protection of the sound acquisition sensor can be automatically realized, and meanwhile the fault information ofthe sound acquisition sensor can be provided, so that the labor amount of maintenance workers is reduced, and the service life of the sound acquisition device is prolonged.

Description

technical field [0001] The invention relates to the technical field of steelmaking and smelting sound collection, in particular to a sound collection device capable of automatic dust removal and timely cooling. Background technique [0002] During the converter steelmaking process, the blowing noise in the converter smelting process can be used to reflect the slag situation in the furnace, and workers can use this to guide the blowing operation. During converter smelting, the temperature in the furnace is as high as 1,400 degrees, and the temperature around the furnace body is as high as several hundred degrees. The temperature environment is extremely harsh. In addition, during the process of iron loading and blowing, there are a lot of spills and small carbonized dust. In addition, blowing will cause splashing, which will cause large-area flame spray and large-particle viscous high-temperature steel slag pollution. After cooling, it will be adsorbed on Caiyin The inside o...

AI Technical Summary

Problems solved by technology

[0004] 1. Nitrogen blowing is far away from the sound collecting sensor, and the blowing cannot remove the dust near the sound collecting sensor. secondary pollution;

[0005] 2. Regular purge cleaning is adopted, which cannot avoid the high temperature damage caused by the spray flame jet. The spray flame exists for a short time, and the instantaneous temperature is high, which can reach thousands of degrees. Once it is close to the sound sensor, it is easy to damage it;

[0006] 3. It is impossible to remove the pollution of large and viscous steel slag splashed in time. The high-temperature sprayed steel slag is easily adsorbed on the pipe wall, and it will be extremely difficult to clean up once it cools down.
