Dynamic monitoring system and method for material levels of stock bins on top of submerged arc furnace

Abstract

The invention relates to a dynamic monitoring system and method for material levels of stock bins on the top of a submerged arc furnace. The system comprises a plurality of stock bins, wherein a guide rail is arranged above the stock bins, a feeding device is slidably arranged on the guide rail and used for feeding all the stock bins, material level instruments are arranged on the feeding device and used for inspecting the material levels of all the stock bins along with the feeding device and generating material level signals, and dynamic monitoring of the material levels of the stock bins is achieved. According to the dynamic monitoring system and method, the material levels of the stock bins are inspected through the at least two material level instruments mounted on the feeding device, the material level signals are output as two sets of continuous curve data containing time information, position information, the material levels of all the stock bins and the material levels between the stock bins, the at least two sets of signals are mutually redundant and mutually overlapped for verification, the reliability is quite high, and a reliable basis is provided for full-automatic control of submerged arc furnace production and optimization of distribution system design.

Description

technical field [0001] The invention relates to the technical field of metallurgy and chemical industry, and in particular to a dynamic monitoring system and method for the material level of a submerged arc furnace top bunker. Background technique [0002] The submerged arc furnace used in metallurgy, chemical industry and other industries needs hundreds of tons of raw material input every day as the furnace size increases. [0003] In the current mainstream design of the submerged arc furnace, the feeding of raw materials into the furnace is realized through the corresponding way of the submerged arc furnace top bin and the feeding pipe. [0004] The ratio of raw materials into the furnace is completed in the batching stage; the amount of raw materials into the furnace is related to the smelting efficiency, the rate of decline of the material level in the furnace, and the height of the material level. So far, there is no precise control method. [0005] There may be more t...

Problems solved by technology

[0008] Therefore, it is necessary to ensure that the feeding equipment (trolley, etc.) does not overflow the material of the furnace top silo, and to ensure that there is enough margin in the silo after each feeding to realize the sealing of the material tube. For large submerged arc furnaces with top silos, level monitoring is either impossible to automate or expensive
