air cannon. air blaster made in China
Air cannon or Air 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.
Parts of Air Cannon
Cannon body: Store air. Cannon body is made of Q235-B steel plate. Mainly adopt automatic submerged arc welding and carbon dioxide arc welding for steel plate welding. After X-ray crack detection, mechanical properties test, water pressure test for strength and blasting performance test, it is qualified and safe for use.
Outrigger or rings: Fix air cannon.
Water Discharge Machine: In the course of time water and oil may be accumulated in the body. Unload the twisted wire then blocking dirt can be discharged out.
Safety valve: It is spring-loaded safety valve, whose start pressure is 0.4-0.8Mpa(users can self-adjust). If there is a reliable safety valve on the gas source, the safety valve on the cannon may be cancelled.
Piston: It's made of nylon 66, and is sealed by its piston ring. There're a number of rubber plates at the top of the piston. There is a spring at the rear of the Pistons, so that Piston's reduction activities can buffer spring in order to prevent materials entering the Piston and cannon body.
Solenoid valve: It is the main components in air-cannon's action which can be prepared in accordance with the user's requirement. Remarks: air control valve and explosion-proof solenoid valve are used under ground while the effect is the same.
Cylinder: Adopt alloy steel, and is manufactured by the advanced coating technology.
Piston Rubber Seat: Rubber seat is added to the rear piston to ensure that the compressed spring is not overloaded, to keep flexible energy of the spring.
Asbestos rubber gasket: Play the role of pressing and sealing.
Sealing surface: The cannon exhaust pipe end in the body with specialized technology and equipment for grinding, good sealing performance, preventing from leaking when store gas, energy conservation, ensures the air pressure in the cannon body so that make sure the impact effect when it's blasting.
Block clearers consisting of compressed air reservoir with quick opening valve that releases the stored air in a sudden, high-energy blastBlast is directed through discharge pipe to aerate and dislodge material and restore flowWhen air blaster working, air in reservoir or tank go through directly into discharge pipe at very fast blastingImportance is quicker air discharges, greater speed and force of blast and, therefore, greater amount of material affectedAir blasters can be operated manually or by micro-controller in distance based in sequencing timer that controls firing time interval and sequence of one or more air blastersApplications:Designed to easy way to solve bulk flow problems in silos, hoppers, chutes, and storage pilesUsed widely in various industrial fields such as coal, metallurgical, chemical, thermal power, cement and other industriesUse air blasters where vibration is not practical, its safe and easy way to solve blocking problemsCan be installed on hopper where materials will be stocked often, when material stocked in hopper, then activate air blaster to loose material to go back flowingFeatures:Handles large loads: strong and great blast spreads out form discharging pipe, can declog large volume stuck materialsDesigned for high temperature environments : air cannon can work well in high temperature environments, its reliable and stableEnergy efficient: low air consumption since they collect air and are fired intermittently, they require only small fraction of air used to operate pneumatic vibratorsLess maintenance: 25 million times without failure, its convenient to replace partsSelf-lubricating: unique design for air storage tank and piston bearings, no need lubricationsCharacteristics of High Temperature Air Cannon Parameter

a. High Temperature and no Rubber Seals
The Valve internal moving parts and seals do not have rubber parts. High temperature air cannon is particularly suitable for grate cooler, kiln slope, smoke room and where have high temperature operating requirements, which substantially reducing maintenance costs and significantly extended service life. Body moving parts(piston) is inelastic body.
b. Self-lubricating
The cylinder and piston bearings do not need lubricating because of their unique design.
c. Low Maintenance
25 million times without failure, convenient to remove the replacement parts.
d. Long Life
Its key components use the modern design to optimize, good air tightness.
e. Strong Spray Drying
Stronger spray dring 10% higher than similar products.
f. Compatible with others more easily
It has dual connection. Its valves are able to connect with cylinders of other brands air cannon, which reduce the updating cost for the users.
