Structural design of end cover and end shaft of rotary drum dryer
Structural design of the end cover and end shaft of the rotary drum dryer: The type of the end cover is generally designed as an arched end cover except for the flat cover in the small diameter and low pressure rotary drum.
From the aspect of the force, the concave surface sustains compression better than the convex surface, but after assembly with the cylinder, the total axial length is not as compact as that of the convex end cap. The curvature of the arched end cap should be determined according to the diameter of the cylinder and the sustained force. Generally, a small-diameter cylinder or an a concave with arched cover to bear pressure, and the center of curvature is on the center axis of the end cover. The end caps of large-diameter rotary drums are often designed in a double-arch arched convex, which has good rigidity and strength. The end cap can be equipped with accessories such as inspection holes and safety valves.
The structure of the end shaft of the rotary drum dryer is generally a stepped shaft.The driving part is installed on the driving end shaft, and the thrust and shoulder should be designed to prevent the rotary drum from moving along the driving side and affecting the transmission.The driven end shaft can be an bare axis, which can freely expand and contract when the cylinder is thermally expanded in the axial direction. The shaft neck size of the driving end shaft and the driven end shaft at the bearing support part should be the same. When rotary drum bearings are adopted, the structure of the locking nut should be considered at the shaft neck.The end structure of the shaft should be designed according to requirements on the inlet head and the piping of the heating medium into the barrel.
