Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical sand screening machines, in particular to a fine sand screening device capable of preventing hole blocking. Background Art

[0002] The working part of the drum sand screen is cylindrical, and the entire screen rotates around the axis of the cylinder. The axis is generally installed at a small inclination angle. The material is fed in from one end of the cylinder, and the fine-grade material passes through the sieve holes on the cylindrical working surface, and the coarse-grained material is discharged from the other end of the cylinder. When fine sand is processed, a drum sand screen is usually used for screening. However, the current drum screen still has certain defects. When used, the screening holes are easily blocked due to the compaction of fine sand, which affects the screening efficiency and reduces the working efficiency. For this reason, we propose a fine sand screening device with anti-blocking holes to solve the above problems. Utility Model Content
