Their advantages
- Correct separation of dirty/clean side
- Low costs for consumables
- High flow rates possible
Belt filters / Gravity filters
Inclined bed filter SBH
The POLO inclined bed filter SBH cleans many different liquids fully automatically. The special feature is the extremely deep filter trough.
Due to the high hydrostatic pressure, large volume flows are possible. This series can therefore be used not only to supply stand-alone machines, but also for machine groups and central systems.
Short info
- Flow rates up to a max. of 3300 l/min. emulsion possible
- Robust construction
- For supplying machine groups
- Can be used as a central system filter
Wide range of fleece
thus optimised adaptation to the operating conditions. The inlet distributor prevents turbulence. A clean tank must be placed underneath the filter. The purified liquid is usually returned by a pump.
Less fleece required
The POLO inclined bed filter SBH operates with an endless transport chain that carries the filter fleece in a way that is gentle on the material. An extremely deep filter trough is formed, resulting in a high liquid level. This decisively limits the consumption of fleece.
The filtering process is safe and efficient.
Design
The POLO inclined bed filter SBH consists of a steel or stainless steel welded housing with drive and deflection shaft. It operates with an endless transport chain that carries the filter fleece in a way that is gentle on the material. An extremely deep filter trough is formed, resulting in a high liquid level. This decisively limits the consumption of fleece. The control functions, triggered by float switches, are carried out by an external or integrated electrical control box. The filtering process is safe and efficient.
Function
The liquid is fed to the filter via the inlet distributor without pressure or by means of a pump, flows through the fleece and, when cleaned, reaches a clean tank below through the outlet.
The shape of the filter bed allows a high liquid level. This increases the throughput and makes the best possible use of the fleece. The dirt particles are deposited on the fleece and reduce the flow more and more.
These dirt particles (filter cake) represent an additional, high-quality filter layer and thus improve the filter result. The level rises on the dirt side of the filter. At a preset level, there is a belt cycle (approx. 50 mm long).
The built-up filter cake is a valuable filter aid and significantly improves the degree of purity.
Due to the short belt cycles, only a very small part of the filter surface is renewed, so that the essential part of the liquid flows through this “flushing medium” and thus increases the filter fineness.
A hose seal, resistant to all commercially available cooling lubricants, reliably isolates the dirt chamber from the clean side.
A fleece shortage switch (option) gives a signal that the fleece roll needs to be replaced.
