Dewatering device with screen assembly having releasable fastening means

摘要

The screen deck assembly of the present invention comprises a support frame, a screen member adapted to be removably mountable to the support frame, and releasable fastening means for mounting the screen member to the support frame, which in turn is fixedly mounted to the structure of the dewatering apparatus. The fastening means are readily releasable so that the screen member may be dismounted from the support frame, reversed and remounted by again engaging the fastening means into the reassembled screen member and support frame. The fastening means comprises a sleeve member and a pin member adapted for insertion into the sleeve member. The sleeve member has an elongated axially extending hollow cylindrical member which has an annular ring extending radially outwardly therefrom at one end and a plurality of axially extending slits cut in the other end thereof. The annular ring portion of the sleeve abuts against a washer-like ring mounted to the screen member when the sleeve is inserted into a hole in the screen member.
