Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic stop wheels, in particular to a rotary kiln hydraulic stop wheel structure capable of extending the service life. Background Art

[0002] Due to the characteristics of the calcium carbide slag production line, there are more harmful components such as sulfur, alkali and chlorine in the kiln, and the kiln skin in the rotary kiln is frequently knotted and collapsed, which can easily cause differences in the contact surface between the supporting roller and the wheel band, and have a greater impact on the up and down movement of the kiln. If the kiln is not adjusted properly during the kiln adjustment process, the supporting roller will be in an "eight-shaped" shape, which will cause uneven force. When the kiln cannot move up and down freely, it will cause the hydraulic stop wheel to exert force frequently, which is easy to cause damage under long-term stress conditions.
