Abstract

The invention discloses a dust explosion-proof protection system of a grain / feed / granular powder grinding apparatus in an embodiment to avoid the risk of dust explosion caused by dust cloud explosion in a grinding processing region due to generated sparks and induced combustion during grinding processing of the grain / feed / granular powder grinding apparatus. The dust explosion-proof protection system of the grain / feed / granular powder grinding apparatus in the embodiment of the dust explosion-proof protection system comprises a grinding apparatus emergency braking interlocking device mounted in dust explosion-proof association with the grinding apparatus, a powder falling settling chamber and a powder conveying system, a magnetic-absorption separation device for metal foreign bodies, the powder conveying system, an air exhausting system, a dust removing apparatus, a spark detection device, a gas fire-extinguishing device, an explosion-proof device, a temperature monitoring device, a fire-extinguishing water spraying device, an interlocking protector and an interlocking protector control system.

Description

technical field [0001] The invention relates to the field of powder production and processing, in particular to a dust explosion-proof protection system for crushing equipment for grain, feed and granular powder. Background technique [0002] The crushing equipment uses the force of machinery and high-pressure airflow to crush grain, feed and granular powder. The crushing process of the crushing equipment will generate dust and dust in the crushing processing area and form an explosion hazard environment of dust clouds. If the crushing process occurs Sparks and combustion will cause the dust cloud in the crushing processing area to detonate and cause a dust explosion. [0003] Therefore, it is an urgent problem for those skilled in the art to find a dust explosion-proof protection system for comminuting grain, feed and granular powder. Contents of the invention [0004] The embodiment of the invention discloses a dust explosion-proof protection system for grain, feed, and...
