Features and advantages of the equipment:
1. Safety
The equipment is fully enclosed. The equipment is filled with
nitrogen. When drying anaerobic materials or materials containing
flammable and explosive solvents, there is no oxygen in the gas and
it cannot be burned or oxidized, which can effectively prevent the
equipment from catching fire during production. Or explosion
accident, so it is safer than ordinary equipment.
Second, high efficiency
The equipment host uses a bag pulse dust removal system, which
has high dust removal efficiency, the dust is not bonded to the
filter cartridge, and is easy to disassemble and clean. And use the
whole machine back blowing technology (technology) to complete the
equipment counterattack after the equipment is dried, and its dust
removal is thorough. After using this technology, the cleaning
frequency of the bag of the equipment is extended from the original
1-2 days to 12-15 days. One wash.
The equipment is discharged from the lower part of the main
machine, which can be pumped to the material storage device by
vacuum discharge, reducing the operation intensity of workers and
improving efficiency.
3. Environmental protection
After being dried by this equipment, the hot moisture containing
solvent enters the condenser to condense the solvent in the gas
(the solvent recovery rate is more than 95%), which can recover the
solvent and condense the dehumidified dry gas. The recovered
solvent can be recycled again, which can save costs and at the same
time will not cause exhaust emissions to pollute the environment.
4. Energy saving
When the equipment is working, the required internal air pressure
is low, and only a slight positive pressure is required, so the
power of the fan equipped with the equipment is reduced, because
under positive pressure, the hot air is blown upward from the lower
part of the hopper screen, and the wind penetration is strong,
although the material boiling height Not high, but the contact
between hot air and materials is more sufficient, and the drying
rate is faster. After the fan power of the equipment is reduced,
the noise of the equipment becomes smaller and energy is also
saved.
Five, broad spectrum
The hot and humid gas inside the equipment is dehumidified by
condensation. The absolute humidity in the gas is low, and the
drying capacity becomes stronger. It is more suitable for
moisture-sensitive materials that are sensitive to humidity.
For materials with finer particles: due to the low wind pressure,
the escape rate of the materials is small and can be fully
recovered in the secondary dust removal.
The equipment is fluidized during the drying process, and the
material and hot air are in large-area gas-solid contact. The
drying strength is large and the efficiency is high. With the
increase of the equipment and the increase in the air volume of the
equipment fan, the efficiency of the equipment can still be
guaranteed; Unlike the static vacuum drying system, as the
equipment increases, its drying efficiency becomes lower and lower.
The material in the drying process of the equipment is fluidized,
which avoids other adverse conditions such as local material
overheating and deterioration caused by the direct contact of the
material heating surface with the material in the vacuum drying
system.
A brief description of the flow chart of the equipment:
1. Feeding: The feeding of the equipment adopts positional feeding,
the working intensity is small, the material does not stick to the
pipeline, and the feeding is fast.
2. Drying: After the system is filled with nitrogen, the air inside
the equipment is driven by the fan; enter the filter to filter, the
heater is heated to enter the host; in the hopper of the host,
after a large area of gas-solid contact, the two-phase exchange of
mass and heat transfer (Take away the solvent, leaving heat); then
enter the dust collector, the fine powder is intercepted again;
then enter the condenser, perform two-phase exchange of mass and
heat transfer again (take away the heat, leave the solvent), and
then return Fan to achieve circulation. There is nothing inside or
outside of the equipment when drying.
3. Discharging: When the equipment is discharging, open the flap at
the lower part of the equipment barrel and start the vacuum shaking
device to shake the material away.
