Abstract
A rotary kiln is a large-sized and key device for industrial enterprises of cement, non-ferrous metallurgy, chemical engineering and the like. The change of the ellipticity of a kiln shell is data rather essential to the normal operation of the kiln, which is directly related to the service life of refractory bricks in the kiln and the normal operation of the kiln. A rotary kiln shell ellipticity measuring instrument comprises a bridge-shape bracket, an insulating board, a tilting device, a magnet seat, a displacement sensing collector, an insulating rod, an insulating shield, a measurement contact, a wireless transmission module, a wireless receiving module and a microcomputer system. When measuring, displacement measuring is conducted through contacting a displacement rod with the points to be measured of the shell. By sending the data of the displacement sensing collector to the wireless transmission module, real-time wireless transmission of collected data is fulfilled. By adopting the method of wireless data transmission, the measuring instrument has simple structure, low cost, accurate measuring precision and high performance price ratio and is convenient and durable. The instrument is actually used in cement plants and good results are achieved.
