Embodiment Construction

[0038] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

[0039] In view of the difficulty in monitoring the deformation of high-temperature furnace rolls, the high cost of existing methods, and the inability to meet the harsh working environment, the present invention provides an adjustable furnace roll deformation monitoring and alarm based on an infrared beam that is suitable for high-temperature furnaces. The device has good adjus...

Abstract

The invention provides an adjustable furnace roller deformation monitoring and alarming device based on infrared intrusion sensors. One end of each furnace roller is a power input end, and the other end of each furnace roller is a free end; furnace roller deformation monitoring devices are installed on two sides of the free ends of one column of furnace rollers and are infrared emitting/receivingportions separately; each emitting/receiving portion comprises a damping base, a slide board, a damping table, a lifting mechanism, an infrared emitter, an infrared receiver, a processing circuit module and an acousto-optic alarm; each infrared emitter emits a horizontal light beam to the corresponding receiver; when the furnace rollers deform or are broken, the light beam is shielded, a receivedelectric signal frequency map changes and cannot be matched with a reference signal frequency, the acousto-optic alarms give an alarm; the sliding boards and lead screw lifting mechanisms can controlthe specific positions of infrared intrusion devices, and monitoring of different deformation amounts is achieved; the damping tables can greatly reduce the longitudinal and transverse vibration transmitted to the sensors when a furnace body works, monitoring and alarming for furnace roller deformation can be carried out, and the operation safety of a furnace is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of monitoring conveying equipment, and more specifically relates to a method and device for monitoring a furnace roller based on an infrared through-beam sensor. Background technique [0002] The products in the high-temperature furnace are placed on many horizontal refractory rollers with close intervals. The rollers are driven by the power source to rotate continuously, and the products are transferred from the kiln head to the kiln tail by the rotation of the rollers to complete the preheating, heating, heat preservation and cooling of the products. cooling process. Hearth rolls are stable depending on the characteristics of the material itself at high temperatures, but during long-term rotation and operation at high temperatures, bulges and nodules will occur, and bending deformation will inevitably occur. When the hearth rolls are bent and deformed, there will be a lot It is a big safety hazard. It is ...
