Mechanical and electrical industry, chemical industry, coal industry, the building materials industry designated units of the production of air guns, with satisfactory performance of the contract capacity of the legal entity, issued by the state of the pressure vessel manufacturing license. The company produces air guns, gas tank, powder valve, electric bag dust collector dedicated air bags and other products for many years in the country's 30 provinces electricity, chemicals, coal, cement, metallurgy, steel, coking, foundry, etc. The industry widely applied, and in recent years exports to Vietnam, Thailand, Malaysia, Iran, Indonesia, Zimbabwe, Laos, India, Brazil, Saudi Arabia, of Eritrea addressed, Pakistan, Sri Lanka and other countries, and received by users and experts at home and abroad. 

 The company produces air gun is manufactured in strict accordance with the national standard of GB150-1998 "and" JC464-2005 "air gun industry manufacturing standards and" of TSG R0003-2007 Simple Pressure Vessel Safety Technical Supervision Regulation for "national Pressure Vessel Code. JC464-2005 air gun building materials industry standards JC464-92 on the basis of the amendments in the revised standard, I as head of the unit. The company has passed ISO9001: 2000, European Union CE certification, the establishment of a complete quality assurance system and to develop a quality assurance manual, the procedure in accordance with the requirements of the drawings, strict manufacturing processes and the corresponding manufacturing, testing equipment and tools checks at each level, welders, NDT workers have the training and examination of the labor department after passing the certificates. Pressure vessel inspection departments perennial send in my unit on-site supervision checks, stable quality and reliable performance. 
 My company and the Chinese Academy of Sciences jointly vector propulsion technology to the air gun performance is further improved and applied for a domestic and international patents (national invention patent number: 200510071134.3; U.S. patent application number: 11/437.107). March 2008 air gun through the identification of the acceptance of the Expert Group by the Academy of Sciences, technical performance has reached international advanced level. The utility model patent in February 2009 with the air gun exhaust nozzle guide vanes to obtain the approval of the State Intellectual Property Office (Patent No.: of ZL 200,820,070,189.1). Air gun piston sealing system in August 2009 granted to utility model patent (patent number: ZL 2008 2 0147833.0). In 2009, the air gun technology R & D center was identified as a provincial enterprise technology center. 

 Our company adhere "credibility first, customer first" purpose, focusing on the social benefits of the product, and strive to realistic for the user. Product quality, reliable, and abide by the contract, the agency checked. Long-term supply of spare parts, can provide users with typical silo placed the location of demonstrations and electric, pneumatic, automatic control system supporting design information. 
 Product Description: 
 First, use 
 The air cannon block clearer is to prevent and eliminate all types of silos, hoppers, cement preheater kiln and pipe the bifurcation and mining chute, special equipment for the bagging of the material of the slip slope, sticky position occlusion phenomenon. Positions, made of concrete, steel, wood or plastic hoppers. Widely used in coal mines, and underground coal bunker, coal preparation plant, cement plants, foundries, power plants, sinter plants, gas works, chemical plants, chemical plants, aluminum plant, the system soda plant, steel mills, coking plants, pharmaceutical factories, mines, docks, grain, feed mills, concrete processing plants have a silo, hopper, pipeline and mining factories and enterprises of the chute. 
 Second, the characteristics 
 Security: air cannon block clearer Vessel Code specified by the national design and manufacturing. Limited the amount of air each time you use the jet of air in the container is instantaneous, and therefore will not generate a large vibration and impact on the silo wall bunkers and hoppers and other structures. No-spark switch, there is no risk of explosion of the surrounding medium. 
 2, energy: air cannon block clearer is the use of gas stored in the gas tank to a sudden outbreak of the airflow generated by the impact of a direct role in the materials occlusion of the affected area, and broken arch - blocking the flow aid. 
 3, low energy consumption: air cannon block clearer is intermittent work, each filling a very short time, and therefore lower than the energy consumed by the other - blocking the flow aid devices. 
 4, low noise: the expansion of the sound of the release of compressed air almost entirely absorbed by materials in the compartment and intermittent work, so the noise below the health standards of industrial enterprises noise. 
 Third, the principle 
 The air cannon block clearer is the strong airflow of a sudden spray of compressed air, Mach more than one speed or higher than the speed of sound directly into the storage of bulk materials occlusion of the affected area, this sudden release of the expansion of the shock wave to overcome the material static friction materials in the warehouse again to restore the flow of gravity.
