Technical Field
The utility model relates to the technical field of powder conveying and wear resistance of coal mills, in particular to a multi-outlet device for boiler coal mill equipment.
Background
The pulverized coal produced by grinding rotates along with the grinding roller and is thrown above the nozzle ring under the action of centrifugal force and the pushing action of the continuously ground coal and pulverized coal. Primary air uniformly enters the periphery of the grinding ring through the nozzle ring, pulverized coal thrown upwards from the grinding ring is blown to a separator at the upper part of the grinding machine, separation is carried out in the separator, separated coarse powder returns to the grinding machine for regrinding, and qualified fine powder is taken out of the separator by the primary air. Qualified coal powder is taken out of the mill by hot primary air through the separator, enters the hot primary air pipe, and directly enters the hearth through the combustor to participate in combustion.
At present, a multi-outlet device basically tends to be mature, but due to the difference of coal quality and improper material selection, coal dust in operation is a great test for impact abrasion of the multi-outlet device, and conventionally used steel castings or stainless iron serving as a base material is lined with ceramic or high-chromium cast iron, so that the problems of breakage, falling, coal accumulation in plug welding holes, wear resistance, incapability of replacing and the like easily occur.
