Description:

Stainless steel Costerelli float sink tank, manufactured in 2003 but not originally installed until 2005. A three paddled tank designed to capture the floating fraction, and with stainless steel chain driven sinking fraction removal. The separating tank section is 3 metres by 1.5 metres wide and with a 1.8 metres working depth of water. The chain drive, additional side height, floaters auger off-take, and sinkers removal sections combine to give overall equipment dimension of 5.75 metres long, 1.8 metres wide and 2.2 metres high.  


Features:

  • Three slow speed rotating drum paddles convey the flake along the length of the tank, immersing the flake to encourage separation at each drum.
  • The robust stainless steel chains driven by a heavy duty  0.7 kw Bonfiglioni motor and gearbox. They run continuously at very slow speed, and support scraper bars across the width of the tank, which drag the sinking fraction from the base of the tank to the removal section at the front of the feed end.
  • The chains are adjustable to allow for wear in the mechanism. They are also protected by sensors on each side that will detect any sudden tension associated with a blockage, and immediately stop the chains running.
  • The main flake feed is auger/gravity fed from the previous part of the process, and then is force fed by auger under the water at the front end of the tank section by a 1.5 kw Electro Adda motor and Bonfiglioni gearbox. 
  • The three slow turning drum paddles are each driven by Fimet 0.5 kw motor and Bonfiglioni gearbox.
  • The recovered floating fraction is removed with a draining auger to dewater the flake, driven by a 3 kw Lenze motor and Bonfiglioni gearbox.
  • The float sink tank is integrated into the control panel for the entire wash-plant, and is capable of processing up to 2 tonnes per hour of a 17mm bottle flake. Denser product will process at much higher rate.
  • The paddle scraper bars are capable of removing up to around 1000 kg/hour of 17mm bottle flake, which is then processed through a de-watering screw press.
  • The tank has drain valves to the front for full drainage, and to the side at differing depths to aid emptying, or for refreshing the waters.
