Why does the slag three-cylinder dryer need to install the retaining wheel
The double-cylinder dryer is placed obliquely during installation. Under the action of different forces and different directions of self-weight and frictional force, the drum will generate axial force at the corresponding rotation speed, and the cylinder will generate axial force under the action of the axial force. Axial displacement. The function of the blocking wheel is to control the axial movement, so that the axial movement of the cylinder is limited within the allowable range.
The amount of axial movement is mainly determined by the distance between the blocking wheel and the side of the rolling ring. A moderate amount of axial movement of the cylinder can ensure the effective contact between the rolling ring and the supporting wheel of the cylinder, and the large outside of the roller , The pinion should not be larger than the required gear meshing range, and the effect of the sealing device at both ends of the cylinder should be guaranteed.

The most commonly used retaining wheel is the common retaining wheel, which is a pair of devices installed on both sides of the rolling ring close to the ring gear. Its working principle is that when the rolling ring is in contact with the installed conical blocking wheel, the blocking wheel will rotate under the driving of the rolling ring, and it can be clearly judged from which blocking wheel rotates whether the cylinder is moving upward or not. Sliding downward, that is, whether the movement of the cylinder is upward or downward in the axial direction.
During the operation of the double-cylinder dryer, the upper or lower gear wheel should be avoided from rotating for a long time. Once this happens, find the reason for adjustment.
