 · How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle ...

The rake mechanism shall produce * inch pounds of torque and be driven by a 440 VAC, 3 phase TEFC motor of a maximum * HP. The rake drive shall be a cantilevered design with the motorized drive ...

The rake mechanism stirs the sludge through its rotation movement pushing it to the bottom. The discharging is automatic and adjusted to the rake effort, in order to reach the desired thickness. Sensors will give the opening input to the thickener discharging …

 · This strategy is adopted in some designs of thickeners as is the option of including 2 long rake arms and 2 short arms that provide additional raking toward the inside of the tank. Another option is to remove alternate blades on opposing arms for the outer part of the arm to reduce the over-raking at the tank …

Tank Design – Thickener tanks can be supplied as "weld together" or "bolt together" and with concrete or steel bottoms. All McLanahan Thickener Tanks include an overflow launder with adjustable weirs. Planetary Gearbox - Provides the proper speed reduction and torque to drive the rakes. Rakes – Minimum drag rake arm design reduces the

The rake shaft 10 has an upper extension in the form of a threaded stem 10a engaged by a nut member 10b the rotation of which will im- 3 part vertical axial lifting movement to the rake shaft, thereby raising the rake arms with respect to the sediment in the tank. The nut member 10b is part of a rake lifting gear train automatically to function ...

Ovivo thickeners are designed to continuously produce as thick a sludge as possible. Powered by heavy-duty drives, designed to handle the specified torque for 20 years of continuous operation, the sludge is gently mixed by rotating rake arms. This movement keeps it moving towards the center of the tank where it is removed.

The rakes convey underflow sludge to the discharge point and thicken the sludge by creating paths in the compressed zone, which allows escape of entrapped liquid upwards. High Rate Thickeners Perhaps the most significant design optimisation effort in thickening in the last twenty years has been in developing ways to more effectively use the ...

available. Thickener tanks, rakes and feedwell''s are custom designed, based on the feed conditions and raking capacity. A retrofit service is offered to enhance performance of existing thickeners and clarifiers. tHiCkener design MIP Thickeners and Clarifiers are designed …

Thickener tanks may be constructed either from steel or concrete and may reach diameters of 120 meters and in earthen basins up to 180 meters. Most of the chemical process industries prefer the steel tanks construction since they may be elevated above ground level, allow inspection of the tank''s floor for leakages and bring the underflow slurry ...

Eimco 35'' diameter, type BX thickener mechanism, S.O.# 3003-a, previously used on 5''10" side wall depth tank, bridge supported rake mechanism and W-60,. …

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.

The continuous thickener consists of a cylindrical tank. Pulp is fed into the centre of the tank via a feed-well placed up to 1 m below the surface of the suspension. The clarified liquid overflows a trough, while the solids which settle at the bottom of the tank are withdrawn as a …

A thickener according to the invention is provided with a mechanism for operating the rake arms of the thickener without the use of central drive columns and central drive mechanism but comprising a traction means including a plurality of spaced cable carriers distributed and mounted for movement along the peripheral wall of the thickener tank, cable means respectively connecting the outer ...

Circular Thickeners provide a crucial treatment step between upstream process screens, clarifiers, and separators and downstream dewatering and sludge conditioning processes. A well-designed thickener provides storage and equalization, reduces the volume of …

HiFlo™ Thickeners are available in several standard sizes & custom configurations including bolt-together tank, flat bottom, elevated tank, rake lift, and embeeded stave. For complete elimination of the slurry pond, a PHOENIX Belt Filter Press or Filter Press may be added downstream of the HiFlo™ Thickener to dewater the thickened slurry.

or feed open launder. At the tank perimeter, the full-radius rake arm is supported on and driven by the drive unit (tractor). The drive unit runs steel traction wheels on a steel rail at the edge of the tank. Under appropriate climatic conditions, traction thickeners are an efficient, cost-effective design. Thickener tanks

A thickener mechanism for a settling tank is provided in which separate rake arms with scraper blades sweep an outer and an inner annular area respectively of the tank.

If the tank is full of water or clear liquor, the pressure will be at its lowest. As solids start to build up in the tank, the pressure increases as the tank contents are denser. When used in conjunction with rake torque, the mud level height can be estimated. This method is simple, cheap and generally reliable.

The rake arm mechanism inside the lime sludge gravity thickener tank at the Fort Pierce Utilities Authority (FPUA) water treatment plant (WTP) became inoperable and needed to be replaced.
