At present, most of bearings of the granulator are lubricated by grease, and the grease belongs to a grease lubrication medium, has poor fluidity, is easy to volatilize and harden in a high-temperature environment, is difficult to lubricate the bearings timely and sufficiently, needs to be oiled regularly and cannot be recycled; grease lubrication is used, oil of each bearing needs to be filled before starting up, the starting up operation can be performed only after half an hour, grease needs to be filled every 2 hours, and manpower and material resources are wasted. Therefore, the problems of short service life of the bearings of the granulator, complicated lubrication operation, time consumption and the like are not solved effectively.
In order to improve the lubricating and heat-dissipating effects of the bearing, the technical proposal of lubricating by adopting thin oil (engine oil) instead of butter is also presented at present, but the proposal mainly uses the lubricating oil way in the granulator as the key point, and the consideration of an external oil way system is less, so the following defects still exist for improvement:
1) The engine oil needs to work by the circulating pump to carry out circulating flow, and frequent work of the circulating pump not only increases energy consumption, but also easily causes damage to the circulating pump;
2) By adopting a mode of timing work of a circulating pump, the condition of oil shortage in a bearing cannot be found in time, so that the lubrication and heat dissipation of the bearing are not enough in time
3) The lubrication oil way in the granulator is complex in structure and difficult to process.
