Description
Air Cannon
(Air Blaster, Big Blaster, Shock Blaster), also known as air flow-aiding machine or bunker
dredger (block clearer), is a special device for preventing and
removing material arching and blocking in various types of silo,
hopper, preheater kiln, piping crotch and draw shaft and slide
slope. It can be used on steel, concrete and wood-based hopper. It
is widely used in the coal, metallurgical, chemical, thermal power,
cement and other industries. Air cannon, as a good flow assistant
systems, it can effectively prevent the buildup of materials and
solve the blocking problems in transfer chutes, storage
vessels, and process equipment such as preheater towers and clinker
coolers.

Overview
The built-up and
arching of materials in the bunker has already become an inevitable
universal malady of all types of bunkers. It is necessary to equip
bunkers with a most advanced and ideal device preventing arching
and promoting flowing of materials to improve the flow rate of
materials in the bunker and to prevent arching, blocking and
sticking of materials in the bunker with the most safe,
energy-saving and quick method while maintaining the continuity of
the production process. A frequent problem in thermoelectric power
station is the blocking of raw coal bunker, which harms the raw
coal problem in thermoelectric power station is the blocking of raw
coal bunker, which harms the raw coal bunker greatly and may leads
to output drop of the coal mill or even spontaneous combustion and
explosion.
Dredging equipments, like air
cannon and dredging machine, manufactured by our company have been
widely applied in a lot of power plants. With the significant
blocking removal effects, high degree of automation and little
maintenance work; it can replace dangerous and money-consuming
arch-breaking flow-aiding methods with poor effects, such as manual
poking, explosive explosions, mechanical vibration and wearing
plate; which can decrease the labor intensity, ensure the
production safety, and bring intangible economic benefits. Free of
public hazard and pollution, it is recognized as the most advanced
economic, optimal, environmental and safest arch-breaking
flow-aiding equipment.
Introduction to air
cannon
Air
cannon(Air
Blaster), also known as air
arch-breaking flow-aiding machine or dredger, eliminates the
blocking by a sudden expansion shock wave, generated from the
sprayed strong compressed gas with a speed of over I mach (sound
velocity), directly blowing the blocked materials. It can resume
material flow at one operation without causing the static friction
of materials.As
the compressed air is spraried like vortex, it is also called
vortex blaster. It's a new patent of our
company.Applying the
aerodynamics, the equipment can convert compressed air into jet
kinetic force with strong impct force uding a differential pressure
device and automatic-controlled quick exhaust valve in it; so it is
a kind of ideal clean and pollutiong-free block-cleaning soot
-blowing equipment with low energy consumption.
Applications of Air Cannon / Blaster
System
Air cannon such as is also know as
flow-aids device, it is a special equipment to solve the arching,
blocking and sticking problems of the materials in the bunkers,
silos, preheater kilns, pipe crotch and tube wells. The air cannon
system is widely used in coal mines, coal washeries, cement
factories, power plants, fertilizer plants, chemical plants , steel
mills, cocking plants, mine, wharf, feed mills, concrete factories
and other industrial enterprise with bunkers, silos, runnin pipings
and mine chutes.
The euqipment
possesses advantages of simple structure strong impact force, safe,
energy saving, easy operation with automatic control, and damage
free for bunkers. Features:
â— Fast
ejecting effectively breaking material bridge and eliminating
blocking;
â—The combined air cannon with
strong applied force;
â—Operating almost silently with
low noise and no polltion;
â—The no-leakage design may
effectively utilize the energy;
â—Materials in the bunker may not
be compressed;
â—Required minimal maintenance:
remove parts simply, since there are no motors and bearings, there
is no need to apply lubrication;
â—The strong ejecting force may be
applied for wide range effectively;
â—The special reset device allows
automatic resetting quickly after ejecting to block the materials
in the bunker enters the body by mistake;
â—The service life is long, and
free maintenance is provided for all parts and components within
one year.
Because of humid or compressing as well as other
reasons, various air arch blocking may be formed in bunkers. To
satisfy different needs, our company provides air cannons in
different specifications:
1. The air cannon with a volume of *0L or *0L
are mainly applied to the bunkers with small volume as well as
small section area for stocking materials with small specific
gravity and better flowability such as grains, sawdust, plastics,
ash, and cement, and it is also applicable to material-feeding
pipeline.
2. The air cannon with a volume of *5L, **0L
and **0L IS mainly applied to small and medium sized bunker to
store average materials, such as chemical material, cement and sand
for casting, gangue, etc. and it is also applicable to small
loading gate.
3. The air cannon with a volume of **0L or
**0L IS mainly applied to bunkers with large volume but small
sectional area for stocking materials with large specific gravity
and poor flowability where materials are easily to be adhered, such
as various medium sized loading coal bunker, raw coal bunker with
large capacity, surge bunker, fine ores bunker and so
on.
4. The air cannon with a volume of **0L is
mainly applied to large coal bunker, fine ores bunker with specific
large gravity as well as others with different
purposes.
Instruction
1. Since
different materials with different characteristics, the crusting
and blocking situation varies. Therefore, there are great
differences on the quantity on the quantity of air cannon applied.
Generally, the finer the power, the more difficult when they are
cleared, and the blocked massive materials are hard to be
eliminated either due to material biting.
2. There are
cylindrical and square bunker, the diagonal line will be regarded
as diameter when it comes to square bunker.
3. Air cannons
with large volume shall be applied under the following
conditions:
A. powder materials
with strong adhesiveness
B. massive material
that may appear biting situation
C. solidified
materials due to long-time storage
D. the bunker with
gentle taper angel and small outlet
E. materials with
strong moisture absorption or sensitive to temperature which may
exert influence on the flowability
4. Application in
places with explosion-proof requirement shall use the pneumatic
control valve and exhaust valve of explosion-proof
type.
