Abstract

The invention relates to a rotary kiln with a flexible support structure. Flexible support devices are arranged on the side wall of a rotary kiln body and are provided with annular shells sleeving the side wall of the rotary kiln body. The inner ring walls of the annular shells are provided with annular grooves, support rings with semi-arc-shaped sections are arranged in the annular grooves, the inner sides of the support rings are fixedly welded on the side wall of the rotary kiln body, a plurality of rolling rings are arranged between the outer walls of the support rings and the annular grooves of the annular shells, the support rings are arranged on two sides of the annular grooves and at positions of the rolling rings, and lubricating grease is filled into the annular grooves of the annular shells. Referred to the design thinking of a needle bearing, the structure of the rotary kiln is radially and flexibly supported, so that the rotary kiln is more stable and reliable and capable of bearing radial tiny waver, and service life of the rotary kiln is prolonged.

Description

technical field [0001] The invention relates to a rotary kiln with a flexible support structure. Background technique [0002] In the well-known technical field, rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, and are divided into two categories: dry production cement kilns and wet production cement kilns. Metallurgical chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants in the metallurgical industry; oxidative roasting of chromium and nickel iron ore; roasting of high alumina vanadium ore in refractory plants and clinker and aluminum hydroxide in aluminium plants; and chrome ore powder and other minerals. Lime kiln (that is, active lime kiln) is used for ro...
