Automatic material watching device and method under blast furnace trough

Abstract

The invention discloses an automatic material watching device and method under a blast furnace trough. A furnace burden conveying belt and a plurality of blast furnace raw material bins are arranged under the blast furnace trough. The device comprises a central control room computer, a material watching assembly and a plurality of signal transmitting elements, wherein the blast furnace raw material bins are arranged above the furnace burden conveying belt; the signal transmitting elements are arranged at the positions of gates of the blast furnace raw material bins correspondingly; the material watching assembly is fixed to the position, above the furnace burden conveying belt, behind the blast furnace raw material bins and comprises a signal receiving element, a controller, a shooting device and a data transmission device; the signal receiving element is in communication connection with the signal transmitting elements; the signal receiving element, the shooting device and the data transmission device are connected with the controller; and the central control room computer is connected with the data transmission device. By applying the automatic material watching device and method, operators can conduct automatic material watching and online material watching under the trough at any time, the material watching effect is good, contrastive analysis can also be conducted, and thesignificance is more prominent when the raw fuel quality or material discharging abnormity and furnace condition fluctuation need to be watched in time.

Description

technical field [0001] The invention belongs to the technical field of blast furnace ironmaking equipment, and more specifically relates to an automatic material checking device and a material checking method under a blast furnace tank. Background technique [0002] Blast furnace operation emphasizes "seven points of raw materials and three points of operation". The quality of blast furnace raw fuel has a direct and important impact on its furnace stability, productivity, and fuel consumption. Therefore, in the blast furnace operation, looking at the material under the tank is the daily and important work of the blast furnace operators. The material under the trough is mainly to observe the physical characteristics of the material such as color, particle size, and moisture at the position of the material conveying belt, and judge the quality change of the raw material and fuel through observation, so as to provide a basic judgment for the operation of the blast furnace. abn...

Problems solved by technology

[0003] During the daily inspection process of blast furnace operators, since the bottom of the blast furnace trough is far away from the central control room, it takes nearly 1 hour to look at the material under the trough each time, and under the condition of dark light at night, the quality of raw fuel The judgment is not accurate enough

Blast furnace ironmaking production is a continuous process. Too many times of checking materials seriously affects the normal work of blast furnace operators. The noisy and dusty environment under the tank also affects physical and mental health; Abnormal quality can easily lead to fluctuations in blast furnace conditions, especially in the case of large fluctuations in the quality of raw materials and fuels, replacement of materials in the silo, etc., or large fluctuations in blast furnace conditions. When it is necessary to know whether the raw material is abnormal, the effect of seeing the material under the tank is more prominent
