The invention discloses a video identification-based charge level diagnosis and self-adaptive control device for a sintering machine. The device comprises a sintering machine trolley (1) and an ignition furnace (2), wherein the ignition furnace (2) comprises a furnace body (201), an ignition burner (202) and a heat-insulation burner (203); the furnace body (201) of the ignition furnace (2) is arranged on the upper part of the sintering machine trolley (1); the ignition burner (202) and the heat-insulation burner (203) are both arranged at the top of the furnace body (201), and the ignition burner (202) is located at the upstream part of the heat-insulation burner (203). The device is characterized by further comprising a charge level video identification device (3) arranged at the downstream part of the ignition furnace (2) and located above the sintering machine trolley (1) in the running direction of the sintering machine trolley (1). The device disclosed by the invention is capableof judging the ignition burner and a fuel gas blowing pipe which correspond to an unhealthy charge level according to the identified charge level color, and the opening degrees needing to be adjusted,of the corresponding electric valve of the ignition burner and the corresponding electric valve of the fuel gas blowing pipe, and then accurately and rapidly detecting and solving the unhealthy condition of charge level ignition, so that unmanned stable production of the ignition furnace is realized.

Description

technical field [0001] The invention relates to a sintering machine material level diagnosis and control device and method thereof, in particular to a sintering machine material level diagnosis and self-adaptive control device and method based on video recognition, belonging to the field of sintering. Background technique [0002] The sintering process is a key link in the ironmaking process. Its principle is to mix various powdery iron-containing raw materials with an appropriate amount of fuel and flux, add an appropriate amount of water, mix and pelletize the material on the sintering equipment to make the material A series of physical and chemical changes, sintered into blocks, which are sent to the blast furnace for the next step. [0003] In order to reduce the coke ratio and smelting cost of blast furnace ironmaking, blast furnaces often require high strength and high reducibility for sinter. In the sintering process, the sintered ore is generally required to have hi...

AI Technical Summary

Problems solved by technology

[0009] 1. Yellowing in the local area of ​​the material surface: This abnormal condition occurs because the local area of ​​the material surface is affected by various factors, and the ignition fails to ignite the solid carbon particles in the fuel layer. If this situation occurs, if the area cannot be raised in time If the ignition intensity is high, the sintered ore produced in this area will be defective ore, which will seriously reduce the yield of the sintering machine;

[0010] 2. The local area of ​​the material surface is white: this abnormal condition occurs because the local area of ​​the material surface is affected by many factors, and the ignition degree is too high, which not only ignites the solid carbon particles in the material layer, but also a part of the iron ore powder The iron has been melted and reduced. If this situation occurs, if the ignition intensity in this area is not reduced in time, an over-melted layer will be formed on the surface of the material in this area, and the air permeability will be seriously deteriorated, resulting in that the sinter in the lower layer cannot be pumped from the upper layer. air, which will cause the sinter in the middle and lower layers of the area to form defective products, and will also seriously reduce the yield of the sintering machine

[0011] At present, in view of these two working conditions where the abnormal ignition causes the local air permeability of the material surface to deteriorate, the existing technology can only be manually judged by the operator after watching the material surface on site, and the overall adjustment of the ignition furnace and gas injection device is increased or decreased. Total valve opening

Not only the labor intensity is high, but also the operation precision is low
