Description

Coal pulverizer clutch system air supply transformation system
Technical Field
The utility model relates to a coal pulverizer clutch system air supply reforms transform and optimizes technical field, specifically is a coal pulverizer clutch system air supply reforms transform system.
Background
The air source of the clutch operated in the earlier stage of the coal mill is compressed by an air compressor to raise the pressure to be more than 0.85Mpa and is firstly sent to an air storage tank, and the air source is supplied to the clutch of the coal mill through the air storage tank. If the pressure of an air source of an air storage tank is reduced to be below 0.85MPa due to leakage or use in the operation process of the coal mill, the air compressor is interlocked and automatically started, the pressure of the air source of the air storage tank is increased to be above 0.85MPa, the air compressor is interlocked and stopped, the air source pressure of a clutch of the coal mill is met through the circulating operation, and the phenomenon that the coal mill clutch is interlocked and jumped due to low air source pressure to influence the system operation is avoided. The air pressure of the clutch air source of the existing coal mill is increased to be more than 0.85Mpa by compressing the air compressor, and the clutch air source is used as the source of the clutch air source, and compared with the transformation optimization technology, the clutch air source has the defects that the air source pressure is unstable, the air compressor is easy to damage when being started and stopped frequently, the overhaul and maintenance cost is high, and the like.
