Units for sewage sludge screening

PACK CURAGE

This Cleaning Pack / Pack Curage set is intended for the screening of sewage sludge. Specially adapted for a grappling hook supply, the feeding hopper receives all the grapple content and regulates the matter flow towards the filtering drum by means of an Archimedes’ screw, leading to the lower part of the trommel.

Principles

This Cleaning Pack / Pack Curage set is intended for the screening of sewage sludge. Specially adapted for a grappling hook supply, the feeding hopper receives all the grapple content and regulates the matter flow towards the filtering drum by means of an Archimedes’ screw, leading to the lower part of the trommel. The pulp is diluted with an internal spraying water ramp. The filtrate consisting of sandy water goes through the openings and flows in a buffer hopper right under the drum, while the waste products are convoyed towards the outlet, by means of an internal helicoidal tape.

Advantages

The cleaning pack is used for the screening and washing of sewage sludge (unloading from water cleaning trucks) with an adjustable feed rate.

Design features

  • The feeding hopper has an adapted opening to the grappling hook dimensions. In order to enable an optimal regulation of matter flow, there is an axeless Archimedes’ screw in the bottom drived by a variable speed motor.
  • We propose 2 drum models, according to the grapple capability. For grapple volume less than 300 liters, the drum is 600 mm in diameter, and for higher volumes the drum is 900 mm in diameter. In both cases, the drum is driven by a variable speed geared motor to optimize the residence time and so the dryness of the outgoing matter.
  • With a 600 to 800 litres storage capacity, the hopper placed right under the drum allows to buffer the sandy water reception, thus reducing the number of evacuation pumps starts.
CONSTRUCTION

The set Cleaning pack is made of AISI 304L SS metal sheet, with the exception of the Archimedes’ screw which is made of high gauge steel.

Feeding hopper
  • Made of 3 mm thick metal sheet. The bottom of the trough has a 8 mm thick PEHD lining. This enables to reduce high frictions and the housing screw wear abrasion.
  • Driving is done by a variable speed geared motor.
  • Junction with the inlet of the drum is assumed by flanges – the screw going out into this flange.
Drum
  • Standard length of 2000 mm, the diameter is chosen following the grapple’s volume.
  • Made of perforated metal sheet, we offer standard slots of 5, 6, 7, 10 and 15mm.
  • The drum is cleaned by an external water ramp with sprinklers.
  • An internal water dilution ramp helps the screening.
  • An internal helicoid, 100 mm high and 200 mm screw thread, ensures the solids’ displacement towards the outlet.
  • The drum is maintained by 2 wheels on the inlet side and axle on bearing on the outlet side.
  • The driving variable speed geared motor is floatingly mounted on an axle with a reaction arm.
