Problems solved by technology
There are more than a dozen types of materials, and nearly a hundred material manufacturers, which may easily cause confusion in the types and quantities of materials loaded, and cause difficulties in material settlement
2. The informatization level of material management is low, the management method is outdated, and the integrity and reliability of the data cannot be guaranteed by manual accounting
3. The material management is chaotic and lacks material tracking management. The dispatcher cannot grasp the feeding situation of the belt anytime and anywhere, and the brain has a heavy memory burden, and cannot accurately coordinate the relationship between the amount of material supplied, the storage of iron-making tanks, and the material line.
4. Manual management of production d

Example Embodiment
[0020] like figure 1 As shown, a raw material distribution and measurement control device for a belt scale includes a belt scale 5, the belt scale 5 is connected to a weighing control instrument 1, and the weighing control instrument 1 is connected to a programmable logic controller 2, the programmable logic controller 2 Connect the material distribution monitoring computer 3.
[0021] Among them, the belt scale 5 adopts SA-600 8-unit array belt scale produced by Nanjing Sanai Company. The belt scale 5 is composed of an array of multiple weighing units, which can work reliably in harsh environments and has extremely high weighing stability. The error can be kept within 2‰ for a long time. The weighing control instrument 1 adopts the 201H weighing instrument produced by Nanjing Sanai Company. The weighing control instrument 1 adopts 87C520 CPU and 24-bit A / D converter, and its function is such that the PID current output can be passed through the governor or frequency converte...

Abstract
The invention provides a belt scale material feed metering control device of successive, efficient and long trouble-free operation time for on-line industry application. In addition, a control method thereof is also disclosed. Compared with the prior arts, the provided belt scale material feed metering control device can measure the coke, pellet, ump ore and other kinds of materials separately, and the feed accuracy rate is 100%, and reduced the work intensity of the dispatcher. The present disclosure solves the multi material feed of a belt scale, the device can complete the data decomposition, query, parameter setting, measurement report, statistical analysis of all kinds of materials and other functions automatically, and obtain accuracy information collection and classification, and provides reliable measurement data for material balance and cost accounting of iron making system, has a very high popularization value.
Description
technical field [0001] The invention belongs to the technical field of metering, and in particular relates to a raw material distribution metering control device of a belt scale in a comprehensive material yard of a large-scale metallurgical enterprise and a control method thereof. Background technique [0002] The transportation volume of solid materials at home and abroad is very large, and there are many types of solid materials involved, mainly including various ores, coal, coke, limestone, sand, clay, cement, concentrate, fertilizer, chemical products, industrial salt, Cereals, etc., and even sugarcane, sugar beet, sawdust, tobacco, cut tobacco, and tobacco stems, most of which are transported by belt conveyors. Since various enterprises have economic accounting requirements for the measurement data of belt scales, the accuracy of belt scale measurement is obvious. especially important. [0003] In large-scale metallurgical enterprises, comprehensive material yard belt...
