Anatomy bucket elevator generate dust explosions specific reasons bucket elevator generate dust cause of the explosion dust explosion requires four conditions: a range of dust concentration; confined spaces; adequate oxygen; ignition source due to the bucket elevator. In the process of filling the hopper at a higher speed impact materials, the material resulting in a large friction force and impact, and the resulting friction between the materials, so that the material between the dust flying out; when unloading, Throws material from the hopper dust also causes more than two parts caused mainly inorganic dust flying, while many materials due to surface friction by excoriation;.. some of the material was hit and damaged, some of the dust off the inside of the two starch The main part is formed by organic dust. After some information and several field tests have shown that the feed and discharge end, the dust concentration bucket elevator is well within the explosive concentration range. In order to control dust leakage , bucket elevators are in a completely sealed state work, the confined space potentially increasing the risk of explosion. Despite the bucket elevator is working in a sealed condition, but the barrel is not very tight, at the interface with the air inlet is entered. Therefore, its interior is a large presence of oxygen above three conditions are met, as long as the source of fire, it will produce a dust explosion. If the bucket elevator running bad, (2) If the bucket; (1) If the grain stream of metal impurities that may impact and friction sparks occur in the course of its flow and prepare Doo and other: there is always the possibility of sparking, the main reason is as follows. hoist belt deviation occurs with the case friction may cause a spark, so chain bucket elevators can not choose, it is best to use a belt bucket elevator, prevent sparks; (3) a hopper or screw off will work with other Part friction may cause a spark occurs; (4) bearing overheating and reach the ignition point of dust clouds; (5) the belt slipping too long and easy to pulley heat and dust clouds to reach the ignition point; (6) outside the fire entered, ignition dust and the like.
