Infrared temperature measurement scanning device of internal cylinder of rotary kiln heat exchanger device

Abstract

The invention discloses an infrared temperature measurement scanning device of an internal cylinder of a rotary kiln heat exchanger device. The infrared temperature measurement scanning device comprises a rotary kiln cylinder, a plurality of surrounded thermal energy converters and a plurality of surrounded thermal energy converter installation brackets, wherein the installation brackets are respectively fixedly provided with a pipeline, the rear end of the pipeline is fixedly connected with an external detector protection shell in which an infrared detector and a control circuit board are respectively arranged; the front end of the pipeline is fixedly connected with an infrared-transmitted glass tube, the front end of the infrared-transmitted glass tube is fixedly connected with an external motor protection shell in which a motor is arranged, the output shaft of the motor is extended into the infrared-transmitted glass tube and fixedly connected with an oblique reflection light lens. The infrared temperature measurement scanning device is a probing scanning mechanism and can be probed into each surrounded thermal energy converter, the probing depth is in the range from 0 to 5m, the scanning device is heat-resistant and can operate at high temperature environment in a long term, and the rotary kiln cylinder in the surrounded thermal energy converter can be scanned by a big angle without a dead angle.

Description

technical field

[0001] The invention relates to the field of an infrared temperature-measuring scanner for a rotary kiln cylinder, in particular to an infrared temperature-measuring and scanning device for a cylinder inside a rotary kiln heat exchange device. Background technique

[0002] Rotary kiln is a calcining and roasting device widely used in cement, metallurgy, chemical industry and other industries. It is a rotary body made of steel and a cylindrical cylinder supported by several pairs of tugboats through several belts fitted on its surface. Due to the high internal calcination or roasting temperature (up to 1500°C), the interior of the rotary kiln needs to be inlaid with refractory bricks to prevent the high temperature calcination from causing the shell temperature of the rotary kiln to exceed the limit and cause softening and deformation. Due to the peeling and collapse of the refractory bricks inside the rotary kiln, it is necessary to carry out real-time te...
