Product Introduction:
The sludge dryer allows the sludge to quickly rush through the
"adhesive phase area" during the drying process at the fastest
speed. At the same time, the ingenious structure allows the sludge
to reach a two-way shear state during the drying process. The dried
sludge is quantitatively and continuously fed into the feed port of
the dryer by a screw feeder. After the sludge enters the body of
the dryer, the sludge is turned and stirred by the rotation of the
blades, and the heating interface is continuously updated. It
contacts the body and the blades and is fully heated, so that the
surface moisture contained in the sludge evaporates. At the same
time, the sludge is transported to the discharge port in a spiral
trajectory with the rotation of the blade shaft, and continues to
be stirred during transportation, so that the moisture seeping from
the sludge continues to evaporate. Finally, the uniformly dried
qualified product is discharged from the discharge port. The
jacketed shell structure is adopted, so that the sludge is evenly
heated at each interface inside the machine, the shaft rotates, the
sludge is constantly tumbling in the equipment, and the heating
surface is constantly refurbished. This greatly improves the
steaming efficiency of the equipment, not only achieving the
purpose of sludge drying, but also realizing the low-cost operation
of the entire device.
Different materials choose different drying processes, and it is
very important to choose the correct drying process. The general
single-stage drum dryer does not dry the material according to its
characteristics, which makes the color of the dried material poor.
Sludge is a material that is not easy to dry, which makes the dried
material dry and wet inside and uneven. The DC vortex plus AC
reciprocating fast dryer is used to make the dried material have
good color, save resources and improve economic benefits.
Features:
1. Because the heat required for drying the equipment relies on
indirect heating by heat conduction, the drying process does not
require or only requires a small amount of gas to take away the
moisture. It greatly reduces the heat loss of this part taken away
by the airflow, improves the heat utilization rate, and is an
energy-saving drying equipment.
2. Stirring and mixing make the material violently turned, thereby
obtaining a high heat transfer coefficient, so the floor area and
space are very small, saving the cost of plant infrastructure. The
drying process uses less gas, the flow rate is low, and the amount
of dust carried away by the gas is small, so the gas dust is easy
to recover after drying, and the recovery equipment is small in
size, which can save equipment investment. For the drying process
that needs to recover the solvent, the solvent concentration can be
greatly increased. Due to the special structure of the paddle, the
material is alternately squeezed and relaxed during the drying
process, which strengthens the drying. The filling rate of
materials in the drying chamber is very high, which can reach
80%-90%. The residence time of materials can be adjusted by
adjusting the feeding speed, stirring shaft speed, material filling
degree and other parameters, which can be adjusted arbitrarily from
a few minutes to a few hours.
3. Sludge dryer can be used for sludge drying in many fields such
as municipal sludge, printing and dyeing sludge, papermaking
sludge, electroplating sludge, etc. It has high thermal efficiency,
wide range of use, low operating cost, and can also achieve
continuous production.
