STEINIG-Oil Skimmer OTF-B (with belt)

otf 4 bSwaying or more depth of water

Features
  • robust industrial design
  • free flying shaft (some sizes with thrust bearing)
  • maintenance-free
  • extreme steep large-volumed drainage
  • clean wiping off
  • no oil block in drainage (in usuable viscocity)
  • small building compact feature (with large capacity)
  • also special construction

 

otf-5 mit bandApplication
For continuous and discontinuous separating oil and liquid grease floating on surface in spots or connected layers, as a thick layer or film or small spots from cold or hot condensate neutral up to basic or acid in calm and strong moving water.

For ground-water rehabilitation (bymeans of deep well), basin of treating, coolant amulsion, industrial effluents, Oil collecting basins, habour basin, refineries, railway depots, industrials washing-separators, shipping, degreasing bathes in galvanic firms (and industrial for metal processing), manufacturers for eatable oils, washing plants (for tankers, cars, lorries, busses, trams, trains, panzer/armor …).

Oils, liquid grease, petrol, kerosene, solvents and similar.

Performance range
oil recovery Q up to 4.000 l/h
submersible depth ET up to 25 m
speed n 0,5 – 49 min–1 (optional Ø)
temperature t up to 130 °C
oil outlet nozzle R 1 – 8″ out side thread
rest water content < > <> 1 %

Functionality
otf 2 bA tension roll holds the belt vertical. Falling out is impossible even if the water has turbulences, wind or if there are solid parts between belt and tension roll.

Oil sticks to both sides of the down moving belt part, transported to top over the driving roll and nearly wiped off dry on down moving belt side, squashing away oil on the inside the belt is impossible with our rolls. Steep drains avoid, in usually viscocity, an oil block or splash over. Oil is quickly drained. Horizontal mounted.

Delivery Dates
Dependend from oil layer thickness, viscosity, belt width, water moving and speed. Rough guidance value at standard speed: belt width in mm = l/h (without obligation).

Construction
Type: OTF-1 B, 2 B (with plastic belt) OTF-4 B (with stainless steel belt)
OTF-3 B (total of polypropylene) OTF-5 B (with gravity-type empty-out)
Wipers: by hand adjustable, very resistent, wear-resistent
Drains: very steep arranged, large-volumed
Total drain: total closed with best sloping position (at size 60 open), oil outlet nozzle with R (Withworth, DIN 259), oil outlet right hand seen from motor, about extra price left hand too
Changing the belt: at mounted bonnet without any disassembly, at bigger units take bonnet away
Driving roll: variable in the width, with free space at the contact surface
tension roll: with free space at the contact surface, special high border and high weigth, falling out of the belt is impossible
Bonnet: sheet steel galvanized, at bigger units black, special resistent special paint
Standard speed: so proportionated that there is the most effective oil recovery, at lowest water share
Gear motor: 0,011 – 0,12 kW, 230/400 V (Size 60 with 0,011 kW, 3x400 V), IP 54, 50 Hz
Counter bearing: from OTF-4 B 200/2 and from OTF-2 B 600
Submersible depth (ET): inched proportion from 250 up to 25.000 mm
Width of belt: at plastic belt 30 – 2.000 mm, at stainless steel belt 50 – 1.000 mm (= 5 x 200 mm)
Paint: first coad, 2-fold hammer effect enamel blue, impact resistant, bigger sizes black but special resistent special paint


Special design

Drainage hose ready to fit, pump, adjustable speed, explosion proofed (ATEX), fire damp protection, hydraulic drive, compressed air drive, level switch for oil collecting tank, heatable drains, tension roll safety (for deep vesseln, agitator container or heavy water moving), chute instead of drain for very deifficult or not running recovery slops / greases or others, protection bars against gross dirt parts, belts with skim off bags for floating pollution.
