Air Cannon 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.
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.

Major Reasons and Forms for
Bunker Blocking
Currently, the raw
coal bunker of domestic thermal power plant often applies the
cement, steel and concrete structures, which mostly are
cylindrical, square tapered (at the bottom) shape, conical and
hyperbolic. The large mouth at top is the inlet, and the small
mouth at bottom is the outlet. Materials drop from the top to the
bottom by gravity. Since the dropping materials flows in the
tapered container, the sectional areas become increasingly
smaller as going down. Then the materials will be pressed, and
the friction increases. Therefore, it is the main reason for
blocking. Otherwise, there are other reasons concerning with the
materials’ water content, the fineness degree, change of
temperature, time for materials being stocked in the bunker, the
increasing friction coefficient between the wall and the
materials. Currently, the blocked materials mainly shape in arch,
parabola and some shape like fireplace. The blocked part mostly
lies in the place top of the material gate within 1.5m and
3.5(but not limited in the range). In this range, a thin layer of
materials may be adhered on those areas within that range, then
the friction increases, and it may expands axially and radially.
The thickness grows correspondingly. Consequently, blockings of
different shapes form.
Â
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.
Control for operation of air
cannon
The operation of air cannon is
very flexible. There are several control modes for your
selection, including single control with manual an pneumatic
mode, single control with electric mode and shoot in group, and
timing automatic shoot. The operation procedure goes as follows:
Open air inlet valve first, then the air cannon will flow over
into cannon automatically, press “start†to send a pulse
electric signal or air signal to quick exhaust valve to start
shooting, and then air cannon will release strong airflow through
exhaust outlet, then it will come back to original state ready
for the next operation cycle in any time. Manual operation of air
cannon is conducted by operating s or using knob in
reversal valve, and automatic control system is executed by air
cannon automatic controller. We can also adopt programmable
controller to control the entire process system. Operator can set
operating order of air cannon system or make separate operation
to designated single air cannon via s on the control panel.
We are aim to provide with a safe and automatic system which can
realize unmanned control of air cannons.
