Elastic drum screen

The invention discloses an elastic drum screen, and belongs to the technical field of material treatment. The elastic drum screen comprises a support, a screen drum arranged on the support, a rolling ring unit arranged on the outer side of the screen drum and a carrier roller unit arranged on the support. The elastic drum screen further comprises a rotatable catch wheel arranged on the support and a check ring arranged on the outer side of the screen drum. And the catch wheel and the retainer ring are jointed with each other so as to prevent the screen drum from sliding down. According to the elastic drum screen, the problem that the screen bars are blocked by viscous materials is solved, the handling capacity is large, the screening efficiency is high, and blocking is not prone to occurring. 本发明公开了一种弹性滚筒筛，属于物料处理技术领域。所述弹性滚筒筛包括支架、设置在支架上的筛筒、设置在筛筒外侧的滚圈单元和设置在支架上的托辊单元。所述弹性滚筒筛还包括设置在支架上的可转动的挡轮和设置在筛筒的外侧的挡圈。挡轮和挡圈设置为彼此接合，以便防止筛筒下滑。根据本发明的弹性滚筒筛解决黏性物料堵筛条的问题并且处理量大、筛分效率高、又不易堵塞。
