Feed screening device for powder concentrator

Abstract

The invention relates to the technical field of steel slag micro-powder processing, in particular to a feeding and screening device for a powder concentrator, which comprises a shell, a control structure for controlling feeding and discharging of coarse steel slag micro-powder is connected onto the shell, a screening structure is connected onto the shell, a cleaning structure is connected onto the shell, and the cleaning structure is connected onto the shell. The shell is connected with a buffer structure, a material returning structure and a rubbing structure; the control structure facilitates uniform feeding and discharging of the steel slag micro-powder coarse materials, the screening structure can screen out the large steel slag micro-powder coarse materials, the buffering structure can effectively prevent the steel slag micro-powder coarse materials from impacting the screening structure, and the material returning structure can discharge the large steel slag micro-powder coarse materials. And meanwhile, diffusion of steel slag micro powder raised in the shell is effectively avoided, the scraping structure can scrape the material returning structure, so that normal work of the material returning structure is maintained, the screening structure can be cleaned through the cleaning structure, and the screening quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of steel slag micro-powder processing, in particular to a feed screening device for a powder separator. Background technique [0002] In the process of steelmaking, more steel slag will be produced, and the steel slag fine powder will have a higher utilization value. After crushing the steel slag, the steel slag fine powder coarse material can be obtained, and the steel slag fine powder can be selected by the powder separator. Before the powder is selected, it is necessary to screen the coarse steel slag powder to remove the larger coarse material, thereby improving the efficiency of the powder selection. Therefore, a feed screening device for the powder separator is needed during the processing of the steel slag powder. [0003] At present, the feeding screening device adopts continuous feeding or manual control of feeding during screening, which can easily lead to overloading of the screen and affect the q...

AI Technical Summary

Problems solved by technology

[0003] At present, the feeding screening device adopts continuous feeding or manual control of feeding during screening, which can easily lead to overloading of the screen and affect the quality of screening. In the case of a long time, it is easy to cause damage to the screen. When the micro-powder coarse material is returned, it is easy to cause the steel slag micro-powder raised inside the shell to scatter from the ejection plate, which is likely to affect the health of the staff
