Title:
BELT TYPE THICKENING MACHINE
Document Type and Number:
WIPO Patent Application WO/2007/083508
Kind Code:
A1
Abstract:
[PROBLEMS] The operation of belt type thickening machine is regulated by changing to
the flocculation unit, belt running speed and lamp (tilted plate) angle. However, as
these are manually operated by operating staff watching the operation condition of
thickened sludge, filtrate, etc. discharged from the belt type thickening machine,
controlling thereof is difficult. [MEANS FOR SOLVING PROBLEMS] There is provided
a belt type thickening machine structured so as to carry out continuous measurement
by means of one or two or more of measuring instruments for fed sludge density,
thickened sludge density, filtrate density and sludge level on belt and, in accordance
with any change of such measurement values, automatically change a flocculation
unit aperture or one or two or more of mixer rotation frequency, belt running speed
and lamp angle, thereby controlling the density of thickened sludge within a
given range.
