Transmission force intermediate temperature control device inside rotary cement kiln

Abstract

The invention discloses a transmission force intermediate temperature control device inside a rotary cement kiln. The transmission force intermediate temperature control device comprises a centering rod, a pushing rod, protective covers and a piston rod connector. The end opening, provided with a compression spring, of the centering rod is movably connected with an elastic collar. Four bearings are symmetrically arranged at the two ends of a thrust bearing. The pushing rod wraps a system composed of the centering rod and the thrust bearing. Two bearing sleeves are arranged in the positions where the bearings are connected with the pushing rod. The end, close to the thrust bearing, of the pushing rod is connected with a belleville spring. The two protective covers are arranged at the top, corresponding to the two ends of the thrust bearing, of the pushing rod. The elastic collar is movably connected with the thrust bearing. A temperature controller is arranged in the elastic collar. The structure is simple, and the thrust bearing of an ach structure is adopted, so that the stress intensity of the bearings is increased. The temperature controller controls the movement of the elastic collar, the condition that the centering rod is blocked in an inner hole of the pushing rod due to high-temperature expansion is avoided, and unnecessary loss produced in production of the rotary cement kiln is reduced.

[0002] Rotary kiln, as the core equipment of cement production enterprises, without interrupting the normal operation of the kiln, various inspections of the rotary kiln are developing towards dynamic, but the hydraulic cylinder piston rod cannot be used to directly push the rotary kiln. The tugboat shaft, so there is a new force transmission intermediate device inside the rotary kiln. In the design process of the intermediate device of the new mechanical structure of the rotary kiln, when the axial force measuring device is used, the driving force of the hydraulic cylinder should be applied to one end of the tugboat shaft. , to balance the axial force on the tugboat, so that it can reach a state of force balance. If the driving force of the hydraulic cylinder cannot act on the axis of the tugboat shaft, then a moment will be given to the tugboat shaft while the thrust is applied to the tugboat shaft. , this not only reduces the accuracy of the measurement results, but also may damage the supporting structure when the thrust is large, so the role of the force transmission intermediate device is to guide the ejector rod so that the thrust of the hydraulic cylinder is applied to the end of the tugboat shaft However, the thrust bearing in the traditional force transmission intermediate device generally adopts a rectangular structure with low force strength, and the centering rod is generally made of aluminum metal, which is usually affected by temperature to a large extent, and due to the long Over time, the temperature inside the equipment is getting higher and higher, especially the temperature of the bearings. If things go on like this, it will cause equipment damage, frequent equipment replacement, and increase production costs. If it is too high, it will be stuck, which will cause unnecessary losses in the production of the rotary kiln, and cannot meet the needs of modern industrial production.
