Krauss-Maffei TSF vacuum drum filterProcess advantages

� Proven design

Krauss-Maffei vacuum drum filters are avail-

able in various materials of construction and

with special cake discharge systems. Con-

tinuous improvement and decades of expe-

rience enable us to best adapt our

equipment to the given application.

� Highest filtration capacities

Number of segments, specially designed in-

lays, suction cells, filtrate pipes, and control

head, combined with maximum depth of

immersion provides highest filtration per-

formance.

� Reduced operating costs

Low energy consumption together with a

simplified maintenance ensure low operat-

ing costs.

Vacuum drum filter in gas-tight design

Krauss-Maffei vacuum drum filters in gas-

tight design are suitable for operating pres-

sures up to 70 mbar overpressure.

� Highest filtration rates and operat-

ing safety

Increased filtration performance and prod-

uct quality ensured by gas overpressure and

optimized hydraulic efficiency. Even the pro-

cessing of toxic products and solvents

under inert gas conditions is possible with

the gas-tight design.

� Optimized sealing

Further improved and maintenance-friendly

sealing cover hood and trough.

� Reinforced hood design

for operational safety at high pressures.

� Control head free of leakage

� Visual inspection of process area

Krauss-Maffei TDF pressure drum filterHigh-pressure filtration

For fine and ultra fine-grained prod-

ucts in particular, pressure filtration

allows an increased specific filtration

rate together with a higher product

quality.

With the closed design, toxic products can

be processed under inert gas. When con-

ventional methods are not sufficient,

Krauss-Maffei pressure drum filters are the

right choice for effective and reliable dewa-

tering requirements. They operate at pres-

sures up to 6 bar and at high temperatures

up to 180°C.

The suspension to be filtered is fed

continuously to the filter trough.

Depending on the application, differ-

ent suspension distribution systems

are available to guarantee optimum fil-

tration properties.

A special ANDRITZ KMPT-design pendulum

agitator prevents sedimentation of the

solids.

The upper surface of the filter drum is di-

vided into cells and is covered by a filter

cloth. Approximately 40% of the filter area is

submerged in the suspension and the drum

rotates at 6-180 revolutions per hour. The

TSF vacuum drum filter builds up a vac-

uum with a liquid seal pump which is con-

nected to the drum cells via the control head

and filtrate pipes. This causes the liquid to

filter through the filter cloth. The solids con-

tained in the suspension is deposited in a

uniform layer on the filter cloth, thus forming

a filter cake.

The Krauss-Maffei TDF pressure drum

filter operates with overpressure inside

the pressure vessel to force the liquid to filter

through the filter cloth. The control head di-

vides the filter drum into different sections

for filtration, washing, suction drying, cake

discharge, snap-blow, and filter cloth clean-

ing.

In the course of one revolution, each point

of the drum area passes through these

zones in succession. The filtrate drains off

trough hydraulically optimized suction cells,

filtrate pipes, control head, and separator

reservoir. It is discharged either by pumping

or by utilizing the barometric height.

The filtered solids layer emerges from the

suspension as the drum rotates, is then

washed, dried by suction, and removed

from the filter cloth. The washing liquid is

applied to the cake either directly by wash-

ing devices (weirs, spray nozzles) or through

a wash belt placed on top of the solids layer.

The filtrate from the wash zone can be

drained off separately from the mother fil-

trate, enabling counter-current filtration

washing. The filter cake is discharged by

means of a discharge device covering the

entire drum width and which is specially

suited to the cake thickness, consistency,

structure, etc. (scraper, roller, string, filter

cloth).

As the drum rotates, it is re-immersed in the

suspension. The filter cloth can be cleaned

before re-immersion, either with water jets

or with cleaning brushes.

10

Krauss-Maffei SSFE vacuum disc filterOperationSuspension feed

The suspension is fed continuously into the

separate troughs and flows in the same di-

rection as the rotating filter discs. Each filter

disc is divided into 30 cells. They rotate at

30-240 rph, and approximately 50% of the

surface area submerges into the suspen-

sion. The feed level in the trough is kept

constant by weir plate or level regulation.

Filtration

A vacuum is produced in the segment-

shaped filter cells, which are covered with a

filter bag. The liquor filters through the filter

cloth, while the solid matter forms a filter

cake of uniform thickness on the filter cloth

and emerges with the disc from the trough.

Filtrate discharge

All cells are provided with a separate filtrate

pipe ending in the sealing plate. The filtrate

flows along the control valve face and the

control valve head to the receiver which is

connected to the vacuum pump.

Washing of the solids

After emerging from the trough the filter

cake can be washed by a special washing

assembly, with can separate the wash fil-

trate from the mother filtrate and remove it

through the control valve head.

Solids discharge

As the disc filter rotates, the cake is dried by

removing the liquid and is discharged from

the cloth at the end of this zone by means

of compressed air. The cake then drops into

the discharge chute.

Control

The functions – filtering, washing, suction-

drying, solids discharge and filter cloth

restoring – are performed successively dur-

ing one revolution of the disc. The division

into zones is determined by the control valve

face.
