The central drive scraper is widely used to scrape and remove sludge from circular sedimentation tank in water supply and drainage engineering. The whole load of the central drive scraper acts on the center of working bridge without central pier and simplifies the civil construction mechanism. Usually used in pools with diameter less than 18 meters.

The sewage from the central drive scraper flows evenly around the pond through the central draft tube. With the decrease of flow rate, the suspended matter in the sewage settles at the bottom of the pond. The bottom scraper scrapes the sediment into the central pit and discharges it from the sludge pipe by hydrostatic pressure. In the course of operation, if the scraper, scraper arm are stuck by foreign body, or excessive mud accumulation and other unexpected reasons lead to transmission over-torsion, the over-torsion protection mechanism will cut off the power supply, automatically stop the machine and alarm.

Application Characteristics of Centrally Driven Mud Scraper

(1) New transmission mechanism and overload protection device are adopted.

(2) The effect of scraping and collecting sludge is good and the water content of discharged sludge is low.

(3) Compact structure, less floor area and convenient operation and maintenance.

(4) It runs smoothly.

Material Material of Center Drive Mud Scraper
