Thickeners
Shivpad Thickeners function essentially to increase the solids content of sludge from Clarifiers or any other sedimentation tanks by removing a portion of the liquid fraction. This thickening of solids help decrease in sludge volume which in turn is beneficial to subsequent treatment processes. These units covered under the manufacturing range of Shivpad are also available in similar constructional features of Clarifier units.

Thickener – TYPE SPT – A
BRIDGE MOUNTED CENTRAL DRIVEN TYPE

Bridge truss spans the full diameter of the tank.  Feed well, drive and rake mechanism are supported by the bridge truss. Worm and worm wheel type drive head powers and vertical centre shaft carry the rake arms.  Feed enters through the central feed well. Clear overflow is collected in a peripheral launder whereas the settled solids  are desludged from the central sludge pocket.


DRIVE HEAD WITH MOTORISED LIFTING DEVICE ASSEMBLY
 
TYPE SPT - A THICKENER TANKS
TYPE SPT - A DRIVE HEAD WITH OVERLOAD ALARM ASSEMBLY
Shivpad  offers an overload alarm protection to provide positive warning to protect against equipment damage should excess loading occur.  The electro-mechanical overload alarm is mounted on the worm shaft end of the drive head.  Alarm and drive cut-off switches are provided to warn of an impending overload or to stop the equipment, if the capacity of the load is exceeded than the desired level.  Manual or motorised lifting devices can be optional for the user of Shivpad thickener mechanisms.

Thickeners are also available to meet out tougher operating conditions, especially acidic effluent handling. The steel rubber lined tank with steel rubber lined Thickener structurals provided with lifting device facility gives absolute protection for operation under acidic conditions. Manual or motorised lifting devices can be optional for the user of Shivpad Thickener Mechanisms. These devices are designed to lift and lower rake arms during overload conditions while they are rotating. All these mechanisms are factory assembled for ease of erection and adjustment in field.

 
THICKENER TYPE SPC - B
PERIPHERAL DRIVEN TRACTION TYPE

Stationary centre pier partially supports the rake mechanism and serves as pivot about which rake rotates.  Traction bridge is supported on a turn table at one end and driven by a traction carriage assembly at the other end. Feed is introduced into a feed well at the centre of the tank.  The rakes supported from rotating bridge scrapes the settled solids to central sludge pocket.  Clear overflow is collected in a peripheral launder and the settled solids are discharged from the central sludge pocket.


Thickener – TYPE SPT – C
CENTRE PIER TYPE

The drive mechanism  is supported by a stationary centre pier.  A structural steel cage suspended from the drive mechanism carries the rake arms.  A structural bridge extending from centre to periphery of the tank serves as walkway.  Feed is given to the tank serves as the centre of the machine. Clear overflow is received at the peripheral launder and sludge raked by the rake arms is discharged from the sludge pocket.
