Description

Technical Field

[0001] The utility model relates to the technical field of mineral material batching, in particular to a mineral material multi-point automatic batching weighing device. Background Art

[0002] Sintered ore is the main raw material for blast furnace smelting. Its quality is directly related to the stability and smoothness of the ironmaking production process and other technical and economic indicators. Sintered ore is required not only to have high grade, high strength and reasonable particle size composition, but also to have stable basicity. Fluctuations in basicity will cause fluctuations in blast furnace temperature and slag making system. In severe cases, it will cause suspended material or collapsed material in the blast furnace, which will have an adverse effect on ironmaking operations and ultimately lead to an increase in coke ratio and a decrease in blast furnace output. The improvement of sintered ore basicity stability has an important impact on the output and quality of sintering and ironmaking.

[0003] After massive searches, it was found that in the prior art, such as the application number CN202221345941.5, there are technical problems in an automatic raw material ore batching weighing device. It can be seen that the existing raw material ore batching weighing device has a low degree of automation and requires manual weighing of each raw material separately. The process of weighing more or less requires continuous heavy weighing and is cumbersome and inefficient. It is also impossible to weigh ingredients with multiple different formula ratios at the same time. If the formula needs to be changed, the weighing value needs to be reset, and the batching efficiency is low.

[0004] Therefore, it is necessary to provide a multi-point automatic batching and weighing device for mineral materials to solve the above technical problems. Utility Model Content
