Description

Technical Field

[0001] This utility model relates to the field of slag screening technology, specifically a slag screening device with a multi-stage screening structure. Background Technology

[0002] Slag powder is short for granulated blast furnace slag powder. It is an excellent concrete admixture. Standard granulated blast furnace slag is dried and ground to achieve a considerable fineness and a considerable activity index. Slag requires the use of screening equipment during screening.

[0003] The existing Chinese utility model patent with publication number CN206083109U discloses a slag screening device, belonging to the field of slag screening and processing equipment. It provides a slag screening device that can improve the screening effect of needle-like and flaky materials in slag. The device includes a screen plate, a mounting frame, and a drive mechanism. Mounting columns are arranged around the mounting frame, and a vibration spring is installed on each mounting column. The screen plate is mounted on the vibration springs. The output shaft of the drive mechanism is connected to the screen plate, and the drive mechanism can drive the screen plate to reciprocate. Rectangular screen holes are provided on the screen plate, and the length-to-width ratio of the screen holes is greater than 4. The screen holes include longitudinal holes and transverse holes. The length direction of the longitudinal holes is perpendicular to the direction of the reciprocating swing of the screen plate, and the length direction of the transverse holes is parallel to the direction of the reciprocating swing of the screen plate. This utility model improves the screening effect of the screen plate on needle-like and flaky materials while ensuring that coarse particles are not screened, thus realizing the screening treatment of needle-like and flaky materials and coarse particles in slag.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it was discovered that slag requires screening devices during screening. Traditional screening devices have low screening efficiency and require multiple screenings of the slag, resulting in multiple manual handling processes. Furthermore, the excessive amount of slag discharged during screening can cause blockages at the outlet of the subsequent device, requiring manual cleaning. All these problems affect the use of the equipment. Utility Model Content
