The invention relates to a rotary kiln with a flexible support structure. A flexible support device is provided on the side wall of the rotary kiln body. The flexible support device has an annular shell sleeved on the side wall of the rotary kiln body. There are annular grooves on the inner ring wall, and a first support ring with a semi-arc cross section is provided in the annular groove. The inner side of the first support ring is welded and fixed on the side wall of the rotary kiln body. A plurality of rolling rings are arranged between the outer wall of the ring and the annular groove of the annular housing, and a second supporting ring is respectively provided at the rolling rings on both sides of the annular groove, and the annular groove on the annular housing Filled with lubricating grease. The present invention learns from the design ideas of needle roller bearings, aiming at the structure of the rotary kiln body, can realize radial flexible support, makes the rotary kiln more stable and reliable, can withstand small radial movement, and prolongs the service life of the rotary kiln.
Description
technical field [0001] The invention relates to a rotary kiln with a flexible supporting structure. Background technique [0002] In the known technical field, a rotary kiln refers to a rotary calcining kiln (commonly known as a 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, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and 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 bauxite in refractory plants and clinker and aluminum hydroxide in aluminum plants; roasting of chromium ore in chemical plants And minerals such as chromium ore powder. Lim...
