Top Quality & Good Price Vertical Shaft Lime Kiln / VSK kiln
Vertical lime kiln, just like its name, the shape is erect. It is used for calcination
limestone. Due to has low energy consumption, less cover area, less
investment, wide applicability fuel, and more advantages, the
vertical lime kiln is also widely used in metallurgy, construction
materials, calcium carbide, Nanometer calcium carbonate, aerated
concrete, sugaring, etc.
In order to guarantee the quality and capacity of lime, finalize
the fully automatic production during the production, the special
and main equipment for the kiln as follows:
1. Limestone batching electric weighing system
Required limestone and coal mixed as the feeding material in the
kiln processing. The ratio of two mixed material is very important,
the two weighing system can accurately measure the raw material
quality, and mix them with special batching method. In addition, if
any changeable in particle size of raw material or calorific value
of coal, should adjustable the ratio of two raw material, operation
the computer will finalized in control room.
2. Intelligent master controller
Main winch system, make the rotation motor change into frequency
control of motor speed. During the handcart route from feeding to 0
~ 6 m after adopt step-less speed 6 m is set to 1 m/s running
smoothly, terminal schedule 6 m for step-less speed running ahead
of time, until discharge. This design ensures the skip smooth
operation, greatly reduce the vibration and the failure rate of
inclined bridge. The elevating capacity will improve 60% than no
frequency control of motor speed. Make the main winch system
greatly reduced maintenance. The handcart running status and
adjustment wire rope length no more downtime. Practical life of
wire rope improve more than 3 times.
3. Rotary distributing devices
The key of feed material inside kiln ensure the uniform flat,
rotary distributing devices could make the raw material even
scattering into the material surface, the shape of surface is
adjustable. Application of frequency conversion governor, PLC
control, makes the fabric are accurate and reliable.The case of the
key structure, such as cylinder, baffle, cloth guide groove, and
tablets, etc. With high temperature resistant, corrosion resistant
stainless steel. Rotating parts with special high temperature
resistant surface bearing, makes the equipment operation and
reliable, and can in a terrible environment without any medium. For
the high quality of the calcined limestone provides a good
technological conditions.
The special structure of the case after mixing limestone and coal
can be scattered to the material surface. Greatly reduced due to
uneven fabric in furnace nodules, waste of fuel. Like Shuicheng
steel, Jinan steel and other units in the replacement after this
kind of case, after the measured production ash per ton coke saving
(or coal) in more than 15 kg.
4. Intelligent detection of material level gage
Level gage install the top of kiln, though remote control in the
industrial control can be very convenient to detect a material
fabrics, to control to determine whether the skip loading, lime
discharge device is working.
Detection of material level gage part adopts high temperature
(above 600 ℃) corrosion resistant materials. Control system adopts
imported transducer and PLC module, in order to meet the
measurement system can long-term reliable operation in harsh
environment.
5. Simulation hood
Active lime vertical kiln in the calcination process, for the size
of the wind and uniformity, the degree of the activity of lime and
calcined raw cooked evenness is important.The hood cap is to use
the computer simulation design. It can make for uniform wind. The
furnace condition caused by uneven air supply partial burn, over
burnt, less burnt phenomenon is greatly reduced, greatly improving
the quality of active lime. In addition, because of the special
structure, hood it than other cap to avoid blowing ash up clogging
gas path and influence the furnace condition. At the same time also
cap ash discharge smoothly than others. In the rough supply
environment, it also has properties, such as pressure and
resistance to high temperature deformation.
6. Pan discharging lime machine
This equipment is mainly composed of motor, reducer, transmission
shaft, rotary blade, and other parts.
7. Two section seal valve lime discharging machine
In the vertical kiln production, to ensure the quality and quantity
of finished products of lime, must be kept combustion air
continuous production. The two section seal valve lime discharging
machine is one of key equipment during the efficient automatic
discharging lime. A full set equipment is composed of upper and
lower two dampers connection in series. Each damper is consists of
damper box, damper, damper shaft, damper spacer, inspection door,
pneumatic system and lubrication system. Two damper take turns to
open and close alternately, discharge the continuous fall lime to
the final belt conveyor. Due to the damper seal during the
discharging lime, make the combustion air continuously supplied, no
any link from the bottom.
