Description: Height adjustable baffle component fitted on solid liquid separation tanks, horizontal decanter centrifuges, water baths and screening equipment. Modifying overflow plate effective height controls liquid level elevation, overflow throughput and liquid ring thickness for solid liquid separation workflows.
Altering vertical height of baffle top edge:
1. Higher plate position → deeper internal liquid layer inside equipment → reduced overflow volume.
2. Lower plate position → decreased liquid level → increased overflow throughput.
For horizontal decanter centrifuge applications: adjusting overflow weir height modifies settling chamber liquid ring diameter, changes liquid phase residence time and directly influences clarification performance and solid cake moisture content.
1. Liquid level control: Defines maximum allowable working liquid level for tank; surplus liquid overflows across plate top edge.
2. Overflow flow rate regulation: Controls discharge velocity and processing capacity of overflowing liquid stream.
3. Separation interface tuning (decanter centrifuge): Modify liquid solid separation boundary to optimise separation performance.
4. Stabilise process conditions: Buffer feed rate fluctuation and prevent uncontrolled material spill over.
5. Floating scum interception: Retain floating impurities and allow clarified liquid to overflow as required.
1. Slide in insert plate type: Installed within slide grooves; locked by bolts after vertical positioning; most widely adopted design.
2. Double plate staggered overlap adjustable type: Two overlapping plates with offset positioning to change effective overflow height.
3. Long slot kidney hole adjustment type: Long adjustment slots enable fine vertical re positioning after loosening fastening bolts.
4. Flanged multi position hole type (decanter centrifuge end cover): Multiple locating holes for step wise overflow plate position adjustment.
