Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a screening equipment for converter repair material raw materials. Background Technology

[0002] Converter repair refractory is a refractory material used for repairing converter linings. Its raw materials are composed of aggregates (5-30mm), fine powder (0.074-5mm), and additives (≤0.074mm) of different particle sizes mixed in a certain proportion. The particle size distribution directly affects the density and sintering performance of the repair refractory. Therefore, a sieving device is required for screening during the mixing process.

[0003] Currently, most screening devices use vibration for effective screening. However, because converter repair materials contain some sticky powders (such as silica fume), these powders easily clog the screens during screening. This results in a significant amount of non-compliant material being screened, affecting subsequent use. To ensure a high pass rate after screening, the screens need to be cleaned regularly. However, cleaning the screens is tedious and time-consuming, reducing screening efficiency. Utility Model Content

[0012] This utility model provides a screening device for converter repair material raw materials, which has the following beneficial effects: (1) This utility model uses a cylinder to drive a pull rod to reciprocate, causing the rotating shaft to move reciprocally under the drive of the pull rod. During the movement of the rotating shaft, the driven gear and rack drive the rotating shaft to rotate, which in turn drives the mounting block connected to the rotating shaft to rotate.

This effectively avoids the accumulation phenomenon that occurs after the raw material enters the screening box all at once, thereby improving the screening effect of the screening box.
