Peripheral Drive Sludge Scraper_

Product Overview

This ZBX peripheral drive sludge scraper is vital pre-sludge-collection equipment belonging to Complete sludge treatment equipment and indispensable component of full Integrated sludge dewatering system, standard matched facility for Full set municipal sludge processing machine and front-end feeding device ahead of Industrial sludge thickening & dewatering equipment, which steadily supplies qualified raw sludge to follow-up Automatic sludge dosing & conveying unit. It is specially designed for automatic sludge discharging of secondary sedimentation tank with central-inlet peripheral-outlet layout, equipped with two optional sludge draining modes including self-suction and siphon suction to finish continuous tank bottom sludge extraction and floating scum removal simultaneously.

Features

• Wide applicable circular tank diameter Φ10000~Φ60000mm and tank depth 4000~6500mm, flexible customized dimension matches various civil construction of Complete sludge treatment equipment and Integrated sludge dewatering system
• Controllable peripheral linear speed at 2~3m/min keeps stable sludge gathering concentration to realize uniform feeding for downstream Full set municipal sludge processing machine and Industrial sludge thickening & dewatering equipment
• Dual sludge discharge solution of self-suction and vacuum siphon can be selected according to actual water level difference and sludge viscosity to optimize inlet stability of Automatic sludge dosing & conveying unit
• Integrated all-in-one slip ring collector ensures stable power and control signal transmission during full-circle rotary operation, improving continuous running reliability of whole Complete sludge treatment equipment
• Combined stainless steel plus rubber scraper blade plus automatic flushing scum hopper design realizes synchronous sludge suction and floating dross discharge, optimizing effluent quality of secondary sedimentation tank for whole sludge treatment line
• Integrated steel overhead bridge plus underwater suction piping compact layout saves pool bottom space, convenient for later inspection and maintenance of Integrated sludge dewatering system.
