SLUDGE COLLECTING APPARATUS USING UNDERWATER PULLEY BLOCK

摘要

PURPOSE: A sludge collecting apparatus using an underwater pulley block is provided to effectively remove sludge sinking at the bottom by operating active post and passive post simultaneously. CONSTITUTION: An active scrapper(104) is attached at the front of an underwater pulley block(100). An active post(102) can be rotated by an active hinge(106). A passive post(103) can be rotated by a passive hinge(107). A supporting plate(110) and a pin(111) form a link(112) at the top of a frame(101) of the underwater pulley block(100). A rod(113) connects the active post(102) and the passive hinge(107). Sludge accumulated at the bottom of a structure(200) is discharged through a collection hole(202).
