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.
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.
Automatic Control
System
We have intelligent
control box dedicated for air cannon developed by our company which
is superior to universal PLC in performance. Dedicated equipment,
which can be easily programmed and not need profession skill, have
a sound communication function and reasonable I/O setting, which
can meet your various needs such as linking up network,
multi-computer management, sounding alarm and so on.
Â
There are 3 working
modes:
1. Programme-control
automatic mode: in this mode, time sequence control and conditioned
reflex control can be achieved. Also the function of setting start
an stop of equipment can be achieved, and then operator can set the
start and stop time of equipment according to actual situation so
as to obtain the best result.
2. Remote
microcomputer control: operator can control every start or stop
involved in equipment control by controlling microcomputer
through mouse (or keyboard).
3. Onsite
manual operation: by press of control cabinet in the
field.
