China [CN] The sand dryer of the SINONINE company is
an advanced development in the field of drying various materials in density and
size.
Reducing the cost of kW consumption of the
drive station and saving heat - this is the task implemented in this unit.
The problem is solved by organizing three
contour systems of material movement inside the drum casings, distributing the
loads of material and heat throughout the device evenly.
By increasing the contact area of the
coolant and the product, it was possible to reduce the equivalent fuel
consumption per ton of dried material and increase the efficiency of the
device.
Due to the uniform distribution of material
throughout the drum, it was possible to reduce the consumption of kW drive
devices.
Due to infrared radiation from heated metal
inside the drum, the thermal power of the whole unit increased and as a result,
the equivalent fuel consumption fell.
Together, these solutions have
significantly reduced the length of the drum - which allows you to take up less
space and integrate into technologies with limited space.
The presence of a lined furnace zone allows
you to distribute the torch of the burner and flue gases over the entire area
of the entrance to the drum, increasing the area of the heat agent.
A short drum length minimizes facts such as
thermal expansion of the metal, which in competitors leads to structural
deformation and premature failure.
The overall design of the drum is compact,
intelligent and easy to operate.
Principle operation of SINONINE drying machine
By the feeding device, the material enters
the inner part of the rotating drum for subsequent drying. Due to the original
arrangement, the material pushing the blades is tedded and moving in the
opposite direction of the drum, effectively blowing hot flue gases.
Upon reaching the back due to the transfer
device, the material enters the second external chamber and is directed along
it in the opposite direction. Everything also happens in the tracking third
external chamber of the dryer drum.
By heating the inner drum casing and the
combined chamber wall, the partitions are heated from all sides, which
increases the heat transfer area.
Due to the reduced weight, more dried
material moves faster throughout the entire volume of the drum than wet
material and is quickly carried outside the drying chamber.
By adjusting the air flow and the speed of
rotation of the drum, you can adjust its parameters in terms of quality and
quantity of dried product.
Ready, the dried product is unloaded onto a
conveying device for further transfer.
Benefits of SINONINE drying machine
1.The three-circuit solution of the drying
drum due to the internal structure of the increased contact area of the wet
material with hot air, reduces drying time by 48-80% compared with traditional
solutions. The rate of moisture evaporation per unit volume can reach 120-180
kg / m3. And the consumption of fuel equivalent is 6-8 kg / t. product
2.The SINONINE dryer is an innovative
development and is protected by patents..
3.Drying of the material is carried out not
only by a stream of hot air, but also by infrared radiation from heated metal
of internal structures, as an energy accumulator. This increases the energy
efficiency of the entire dryer.
4.The overall dimensions of the dryer are
reduced by more than 30% from their analogues and, accordingly, the external
heat loss is reduced.
5.The thermal efficiency of the
self-isolation of the dryer is up to 80% (simple drums only 35%), and the
thermal efficiency is higher by 45%.
6.Due to the compactness of the
installation, the location is reduced by 50% and the cost of building the
foundation by 60%
7.One of the advantages of the dryer is the
yield of a finished dry product with a low temperature of about 60 degrees.
This fact allows you to apply the product without additional cooling units
directly into the technology.
8.The low temperature of the exhaust gases
extends the filter life by 2 times.
Desired final humidity can be easily
adjusted according to user requirements.
