谷物传送设备上的最大火灾隐患要数静电。静电是在两种不同材料的相对运动中、在不同物质的不断接触和分离过程中产生的。谷物的传送设备,不论是皮带式传送机还是料斗式升运机,都存在着极易产生静电的组成部份。这些部份有皮带、料斗、滚轴和挡板等等。另外,在谷物传送的大多数环境中都存在着谷物的可燃性粉尘。如果静电荷积累到一定的数量而突然放电,就有可能发生粉尘爆炸和火灾。 The maximum fire hazard on grain handling equipment is static. Electrostatics is the result of constant contact and separation of different substances in the relative motion of two different materials. Grain conveying equipment, whether it is a belt conveyor or a hopper lift, is prone to static electricity. These parts are belts, hoppers, rollers and baffles and more. In addition, flammable dust of cereals is present in most environments transmitted by cereals. If the electrostatic charge accumulates to a certain amount and suddenly discharges, it is possible that a dust explosion and a fire may occur.
