Peripheral Driving Sludge Scraper

Peripheral driving sludge scraper, mainly used in the primary and secondary sedimentation tanks of large-scale sewage treatment plant (the water volume ≥ 600m3/h, the pool diameter ≥ 20m), to scrape sludge from tank bottom to mud collection flume, and to collect scum on water surface to scum bucket.

This machine is installed on medium and large size circular clarifier tanks in wastewater treatment plant. Inlet water and sludge discharge pass though the center pit of bottom, Outlet water overflow around tank , which keeps a stable water quality and quantity.

Sludge Scraper Working Principle:

1) Use a mobile steel girder, double lateral trolley, two rotation units with peripheral drive system, a scraping unit, a sucking unit, a scum skimming unit, flow guidance, solids collection bucket, center supports, electrics and control box.

2) The sludge inlet is in the middle, but the flow is deviated by the baffle in order to optimise the thickening. The sludge scraper blades, made in standard section, remove the sludge accumulated on the bottom and collect it in a central pit wherefrom, by a piping, is conveyed to the outlet. Outlet sludge can return or disposal to sludge thickening tank. Scum above water is skimmed to collection bucket for further disposal.

Main features

1) Truss structure, high strength and light weight.

2) Easy to maintain, low operating cost.

3) New designed transmission device together with shaft mounted reducer, compact and efficient.

4) Walking wheel is standard solid wheel, compact and easy to install.

5) Equipped with outdoor electrical components, smooth operation, safe and reliable, both local control or remote control are optional.

6) Excellent performance in scraping and collecting sludge, moisture content of discharged sludge is very low.

7) Scraper is ordered by logarithmic spiral and is equipped with universal wheel, rod is connected by hinge joint. Scraper will adjust itself automatically when encounter with greater resistance, well guarantee working safety.

8) Walking wheel can be rubber wheel, nylon wheel or steel wheels. Products can be customized according to your requirement, stainless steel is optional to spare parts which contact with water.
