Tank suitability Circular
 
 
 

The Zickert 3700 rotating sludge scraper is for circular settlement tanks, offering major energy, operating and maintenance savings compared to rotating bridges. It is suitable for retrofitting to both municipal and industrial circular scrapers, as well as for new installations.

The Zickert 3700 removes sludge without the need for a bridge or a moving electrical connection point. The Zickert rotating sludge scraper features an innovative peripheral drive and rotating scraper design.

By removing the need for a bridge, the Zickert rotating sludge scraper has a lower profile design which reduces the space under odour control covers, so there is less air to be purified and energy costs are reduced.

The circular tank scraper’s electric drive is located on the perimeter tank wall with a static electrical connection point meaning no sliprings are needed. With few moving parts, the Zickert rotating sludge scraper requires less frequent maintenance and are less subject to mechanical wear than conventional bridge scrapers.

Benefits

  • Operation to suit sludge load
  • Stainless steel construction
  • Customisable to tank
  • Low headspace requirements
  • Can be retrofitted into existing tanks
  • Reduces volumes for odour control
  • Static electrical connection

Operation

A fixed drive unit mounted on the periphery of the tank powers a ladder drive ring running around the tank’s circumference. This powers a bottom scraper blade held in place by a central bearing unit. A surface scraper can be mounted on the bottom scraper unit to remove any scum build up.

The bottom scraper blades of the new Zickert 3700 are rotated by a circular rail located inside the tank wall, moving settled sludge to the collection point. The electrical drive is located on the perimeter tank wall, for ease of maintenance and location of the power supply and negating the need for sliprings.

Where surface scum has to be skimmed off, the scraper frame is equipped with an additional top blade which directs scum to a scum beach and trough on the tank perimeter. With few moving parts, the complete Zickert 3700 installation is easy and inexpensive to maintain.

The scraper section is supported by its own wheels, allowing the drive ring and central support to hold the bottom sludge scraper in position without additional stresses.

With only the motor/gearbox protruding above the tank wall, low profile covers can be easily deployed for odour control. This results in less air volume, which enables lower-power, cost-effective purification.
