High-efficiency filtering section rotary drum

Abstract

The utility model relates to a rotary drum of a centrifugal dehydrator, in particular to an efficient filter section rotary drum. A high-efficiency filtering section rotary drum comprises a barrel body and a flange, water permeable holes are evenly distributed in the barrel body, a screen block is arranged on the inner wall of the barrel body, and the high-efficiency filtering section rotary drum is characterized by further comprising a groove; the groove is formed in the inner wall of the cylinder body; a plurality of protruding supporting plates are evenly distributed on the inner wall of the barrel in the axial direction of the barrel, and the screen blocks are arranged on the supporting plates. A groove is formed between every two adjacent supporting plates; the screen blocks are perpendicular to the axis of the cylinder body and arranged on the supporting plate, and barrier strips are arranged between the screen blocks. The supporting plate is arranged on the inner wall of the barrel, and the screen block is fixed on the supporting plate, so that the screen block is not in direct contact with the inner wall of the barrel and is partially suspended, the formation of a sealing water film is reduced, the permeable area of a screen seam is increased, and the water filtering effect is improved; and the screen blocks are divided through the barrier strips, so that region division can be realized, effective plugging is implemented, and the replacement or maintenance efficiency is improved.
