Explosion and pneumatic vibrator
An explosion, people naturally think of moving to thunder bombs, landmines, but suspended in the air that long flying dust, can also cause huge explosions.
1942, China's Benxi coal mine has occurred in the world's largest coal dust explosion, 1549 people were killed and seriously injured by 246 people.
Flax dust explosion accident in Harbin flax factory in 1987, 58 people died, light seriously injured 177 people.
At the beginning of April 2011, the occurrence of dust explosion, polishing workshop of a Zhejiang motorcycle parts factory at the end of April, the province is also a lumber mill, dust explosion and dust also occurred; a starch plant in Hebei last year, Qinhuangdao City explosion, resulting in 19 deaths.
In May 20, 2011, Foxconn group Chengdu company polishing workshop dust accident caused an explosion, killing 2 people were killed and 16 people were injured, of which seriously injured by 3 people
At least 65 people were killed in a blast in Jiangsu, Kunshan, on August 2, 2014. Explosion caused by dust encountered fire accident.
The strict definition of dust is the solid particles suspended in the air. The habit has many names of dust, such as dust, dust, dust, dust, sand and dust, powder and so on, these nouns have no obvious boundaries. International Organization for standardization, the particle size of less than 75 m solid suspension is defined as dust.
The most common combustible dust coal dust, magnesium powder, aluminum powder, zinc powder; sulfur powder, powder dust, carbon, activated carbon, electric carbon, flour, starch and corn meal; fish meal; cotton, flax, tobacco and sugar; wood powder, plastic, paper powder; dye; black powder, gunpowder, explosives: TNT etc..
In China, a lot of industrial powder industry, there is the presence of combustible dust in the workshop, and in the powder industry in the production need to be equipped with vibration device, the role of: pipeline transportation. Hopper blanking, compaction detection, screening, conveying, dust removal, anti blocking, packaging and other links. And in this kind of combustible dust workshop must not use electric vibration motor and inferior pneumatic vibrator. (the former has the possibility of electric spark and leakage) (the latter will be due to improper friction and heat and produce electrostatic sparks) and become a security risk. Pneumatic vibrator is the best choice in this environment. Explosion-proof pneumatic vibrator for coal dust, coal dust, static electricity, gas, etc., are not affected.
And have the ISO9001:2008 quality management system certification, ISO14001:2004 environmental management system certification, EU CE product safety certification of the enterprise: Fenghua City, Sichuan Power Technology Limited production safety, explosion-proof pneumatic vibrator system can be used for flammable, explosive gas or dust environment. Is the customer's production safety backing, can create long-term value and potential growth for customers.
To sum up, with the rapid development of the industry, with the increase of powder explosion accidents, it is very common, and it has brought huge losses to the industry, even far beyond the harm caused by fire. According to the international standards such as NFPA68, NAPA69, NFPA654 Standard Guide to industrial safety production, to the safety of people and equipment, but also due to the explosion of the uncertainty, must raise awareness of security, in the design, manufacture and use of powder equipment with danger, should give powder equipment on insurance industry. Such as the use of high-quality pneumatic vibrator and take appropriate protective measures for explosion-proof.
