Problems solved by technology

[0004] The present invention aims at the technical problems existing in the prior art, and provides an automatic batching system for iron ore materials. The whole technical solution is compact in structure, low in cost, energy-saving and environmentally friendly. The automatic mixing and batching system of ore materials mainly solves the problem of single-cup sampling and testing after manual mixing, which may easily cause large differences in the particle size, chemical composition, and moisture of the first cup and the last cup of sampling, and the effect of manual mixing is difficult to obtain. Guarantee, bring uncertainty to test results, and fail to achieve accurate guidance on-site batching goals

Abstract

The invention relates to an automatic batching system for an iron ore material. The automatic batching system for the iron ore material comprises a supporting frame, a computer control system, a material stocker, an automatic uniform mixing weighing device and an automatic positioning identification conveying device; and the automatic uniform mixing weighing device is arranged on the supporting frame, the automatic positioning identification conveying device is located below the automatic uniform mixing weighing device, and the computer control system controls the whole batching system. The whole technical solution provided by the invention has a compact structure, lower costs, energy saving and environmental protection, the technical solution provides a set of automatic uniform mixing batching system for finishing a plurality of cups of sintered iron ore material at a time, mainly solves the problems that if testing is performed after single-cup sampling and manual uniform mixing, difference in particle sizes, chemical composition, moisture and the like of sampling between a first cup and a last cup is larger, effects of manual uniform mixing are difficult to ensure, indeterminacyis brought to test results, and a target of accurately guiding on-site batching cannot be realized.

Description

technical field [0001] The invention relates to an automatic batching system for iron ore and belongs to the technical field of sinter production and processing equipment. Background technique [0002] In iron and steel production, sinter is the main raw material for blast furnace hot metal production, and the quality status is the key to the stable and high production of blast furnace. The batching plan of sinter is directly related to the quality and cost of sinter, and it is a key process product to be controlled. The sintering cup test is mainly to simulate the sintering production process in the laboratory to conduct tests such as new ore blending tests, development of new sintering technologies, cost reduction and efficiency increase, and on-site production technical problems, so as to guide on-site production to optimize the batching plan and achieve cost reduction. Low, high-quality targets. [0003] In order to determine the batching plan of new minerals, 20-30 sin...
