Description

Technical Field

[0001] The utility model relates to the technical field of soda ash production, in particular to a feed auger shaft head lubrication component. Background Art

[0002] Sodium carbonate is an inorganic compound with the molecular formula of Na2CO3 and a molecular weight of 105.99. It is also called soda ash. It is an important inorganic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze, and is also widely used in daily washing, acid neutralization and food processing. The feed auger is the main equipment used in the alkali transportation process of the calcining furnace in the production of soda ash (sodium carbonate). Its function is to use the feed auger to push the alkali from the premixer into the calcining furnace.

[0003] The existing feed auger shaft head lubrication method uses an open oil circuit. The oil inlet pipe is set on the bearing seat and directly enters the gap between the bearing shell and the sleeve. There is no oil groove on the bearing shell. The gap between the left end sleeve and the bearing shell is in contact with the external environment. This leads to a small lubrication area, insufficient lubrication, and alkaline dust blocking the gap, making the sleeve easy to wear, and then wearing the shaft, shortening the service life of the equipment, increasing the maintenance time, and ultimately affecting product output and reducing production efficiency.
