Abstract

The utility model discloses an infrared temp. Monitoring system for a kiln carcass which is composed of an on-site scanning device and a kiln head controlling device. The infrared temp. Monitoring system for a kiln carcass is used for the non-contact scanning detection and supervision of the temperature field of the cement rotary kiln carcass, and can realize the real-time three-dimensional numeric display, overrunning warning and automatic printing and plotting, having the advantages of simple structure and high cost performance.

Description

Intelligent infrared temp. monitoring system for kiln carcass

The utility model is to belong to infrared temperature field boundary monitoring device, is that the noncontact scanning that is used for cement rotary kiln trunk temperature field boundary detects and supervision.

The effect of monitoring kiln shell temperature field boundary is in time to find kliner coating scaling loss situation, so that in time remedy, thereby prolongs kiln running period.Monitoring cement rotary kiln trunk temperature field boundary has following several types in the prior art: (1) non intelligentization of low speed stepping rectilinear scanning formula, as the kiln shell temp measuring system of Japan thousand wild companies or China; (2) non intelligentization low speed stepping pivot angle scan-type is as the temp measuring system of West Germany Siemens or U.S. L.N. company; (3) high-velocity scanning, infra-red imaging formula are as the temp measuring system of Denmark F.L.S. company.Because the rectilinear scanning formula, thermometric scanner head locating distance kiln is near, is not with clearer, and is frequent mobile, easy break-down; The high-velocity scanning formula, the thermometric scanner head is not subjected to system controlled by computer, again the whole kiln shell of high-velocity scanning, and the link of kiln shell easy burn-out is a clinkering zone in the actual production, moreover the kiln brick burns out need one section process, therefore needn't be at a high speed, full trunk scanning, and with the simplified apparatus structure and reduce the scanner head maintenance capacity.

The purpose of this utility model: realize non-contact intelligent monitoring kiln shell burning zone temperature field boundary, the real-time three-dimensional numeral shows hotspot location and temperature, and overload alarm reaches and prints various real-time parameters automatically, and is simple in structure, ratio of performance to price height.

The technical solution of the utility model is that system adopts infrared technique, pulse work and single chip microcomputer technology to combine simultaneously, thus realized the scanning of temp measuring system intelligent synchronization pivot angle, LED digital display pipe real-time three-dimensional numeral show hotspot location and temperature, the temperature that transfinites automatic sound-light alarm and print automatically simultaneously its position, temperature and date, automatically " interlacing " scan, manually start print temperature field boundary all temps data and draw temperature distribution history, manually start the scanning of various ways etc.

Architectural feature of the present utility model: system is made up of two parts equipment, (1) existing field boundary equipment: comprise infrared measurement of temperature scanner head, air washer and kiln trigger.The infrared measurement of temperature scanner head is a sealed cabinet that has water-cooling system and the special material window is arranged, window can prevent dust, protection against the tide and high again to the infrared ray transmitance, be to drive infrared thermometer in the cabinet by the pivot angle scanner, infrared thermometer has looks field boundary angle and the fast velocity characteristic of ringing greatly, and have main the composition: infrared eye, optical system, prime amplifier, data processor.Air washer is a self contained air cleaning device that has filtration, drifting dust.The kiln trigger is made up of welding collision block, kiln switch and three parts of support.(2) kiln hood pulpit: comprise single-chip microprocessor system, power device and printer plotter.Wherein single-chip microprocessor system is made up of every interface board, display board, printer plotter monolithic motherboard, finger-board, input and output light.Power device is made up of interchange control protection electric circuit, interchange noise killer, DC voltage-stabilizing and pulse power supply etc.

Infrared thermometer is to be used for detecting the kiln shell temperature in the said structure; The general control step pivot angle scanning of single-chip microprocessor system, control figure shows, reports to the police, prints functions such as drawing again; Power device provides the interchange general power of system's armamentarium, and the direct supply of existing field boundary and the driving power of pivot angle scanner have been realized the purpose of this utility model thus.

The detailed condition of the structure of native system is shown by each accompanying drawing

Advantage of the present utility model:

(1). realized non-contact intelligent monitoring kiln shell burning zone temperature field boundary, the demonstration of energy real-time three-dimensional numeral, the sound and light alarm that transfinites, automatic printing are drawn;

(2). scan mode is various, can adapt to need of production. Have automatically " interlacing " scanning, optional rapid scanning, reporting to the police checks scanning, fixed point monitoring, the modes such as fast return;

(3). fixed installation, need not spur back and forth with its stube cable, water pipe, maintenance capacity is few;

(4). the infrared measurement of temperature probe adopts full-closed structure, is adapted at using under the cement plant adverse circumstances of many dust;

(5). system's strong interference immunity can reach more than 100 meter at the existing field boundary stube cable of industry;
