Detection device for material blocking of charging bucket at top of blast furnace and detection method

Abstract

The invention discloses a detection device for material blocking of a charging bucket at the top of a blast furnace. The detection device comprises a material receiving hopper, the charging bucket, an airtight box, an acoustic sensor, a switch, an operation computer, a server and a blast furnace PLC (Programmable Logic Controller) control system, wherein the material receiving hopper is arranged at the upper side of the charging bucket; the acoustic sensor is arranged at the outer side of the charging bucket and is connected with the blast furnace PLC control system; the PLC control system is connected to the operation computer and the server through the switch; a material blocking detection system and a sound-light alarming system are developed and designed in the server; the material blocking detection system is connected to the sound-light alarming system. The invention discloses a detection method for the detection device. According to the detection device and the detection method disclosed by the invention, the acoustic sensor is arranged outside the blast furnace charging bucket and is convenient to mount; in addition, the acoustic sensor can work in a production state of the blast furnace. According to the detection device and the detection method disclosed by the invention, the processing efficiency of faults is improved, the downtime and under-blowing time of the blast furnace due to material blocking is shortened, the yield is increased, indexes are optimized, and stable production of the blast furnace is promoted.

Description

technical field [0001] The invention relates to the field of blast furnaces, in particular to a detection device and a detection method for material stuck in a top material tank of a blast furnace. Background technique [0002] At present, the means of monitoring the filling process of blast furnace top tanks are mainly through tank weighing systems or radar probes, but some blast furnace top tank weighing systems or tank radars do not work well, because tank weighing is affected by external stress Influenced by factors such as furnace roof pressure and other factors, the accuracy is difficult to guarantee; the radar probe of the tank has problems such as response lag, and it is impossible to judge the fault of the tank material in time, and it is also impossible to quantitatively manage the material distribution process. Failure to detect the failure in time caused the accident to expand, leading to the shutdown or slow wind of the blast furnace, which had a great impact on...
