Iron ore screening device for converter

Abstract

The invention relates to the field of steelmaking production, in particular to an iron ore screening device for a converter. The iron ore screening device for the converter comprises a machine frame,material grooves, a vibrating device, a screening device and a crushing machine. The screening device comprises a drum screen and a rotating shaft. A feeding inlet is formed in one end of the drum screen, and a discharging outlet is formed in the other end of the drum screen. The discharging outlet of the drum screen communicates with a feeding inlet of the crushing machine through a pipeline, anda discharging outlet of the crushing machine communicates with the feeding inlet of the drum screen through a pipeline. A filtering net is arranged below the drum screen and is downwards inclined inthe extending direction. The two material grooves are arranged and include the small-particle-size material groove and the large-particle-size material groove, wherein the small-particle-size materialgroove and the large-particle-size material groove are arranged below the filtering net. The vibrating device comprises a vibrating frame, a vibrating connecting plate and a plurality of vibrating plates. A sliding rail is installed on the vibrating frame, and a sliding block is installed on the sliding rail. The end of the vibrating connecting plate is fixedly connected with the sliding block, and the multiple vibrating plates are fixedly installed on the vibrating connecting plate. The iron ore screening device for the converter is simple in structure, saves the time and labor, can rapidlyachieve screening of iron ore and cannot cause blocking of the filtering net.

Description

technical field [0001] The invention relates to the field of steelmaking production, in particular to an iron ore screening device for a converter. Background technique [0002] The converter smelting process needs to add a large amount of iron ore, and the converter smelting has strict requirements on the particle size and proportion of iron ore, so the iron ore raw materials must be screened before they can be put into use. If manual screening is adopted, it is not only time-consuming and laborious, but also the dust is harmful to the health of the operators, and during the screening process, iron ore particles stick to the filter screen, which will easily cause the filter screen to be blocked after a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an iron ore screening device for a converter that has a simple structure, saves time and effort, and can quickly realize the screening of iron ore without...
