Abstract
The utility model discloses a kind of rotary kiln clinker temperature infrared measuring instrument device, be arranged on kiln head cover side.By kiln head cover perforate extraction channel, at channel exit, quartz glass is installed, i.e. hereinafter described quartz window.Infrared survey instrument is fixed on quartz window outside, and the light path of Infrared survey instrument is mapped to the grog of rotary kiln outlet whereabouts by quartz window, then measures the temperature of grog.Because now grog falls from rotary kiln exit, neither affect by dust in rotary kiln, it also avoid high temperature in kiln, measuring accuracy is high simultaneously.The utility model is easy for installation, and measuring accuracy is high, can in industry promote the use of.
Description
Technical field
The utility model relates to cement industry field, is specifically related to a kind of rotary kiln clinker temperature infrared measuring instrument device.
Background technology
Sinter leaching is the subordinate phase of portland cement production process, is also a most important stage.Refer to and raw material obtained in raw material preparation process sent into calcining kiln, through high-temperature calcination, occur series of physical, chemistry with physicochemical change after form the technological process of grog.
Sinter leaching process is all complete in rotary kiln substantially, and its calcining heat has conclusive impact to the quality of cement clinker quality and system hear rate height.If calcining heat is too low, then clinker strength can on the low side, free calcium levels is higher, the product quality caused on the one hand is poor even unqualified, can cause the instability of the overall thermal regulation of kiln on the other hand yet; If calcining heat is too high, then system hear rate can higherly be unfavorable for energy-conservation, and clinker strength also can decline, and refractory life can be caused to decline.Therefore, the Measurement & Control of calcining heat is concerning very crucial rotary kiln.
But clinker temperature is greatly about about 1400 DEG C in rotary kiln, the conventional temp measuring methods such as thermopair therefore cannot be adopted to carry out measuring tempeature.Industrially, conventional mode adopts Infrared survey instrument to carry out thermometric.Traditionally, generally at kiln head cover installation infrared measuring instrument (i.e. colorimetric pyrometer), its measurement point is grog in kiln.According to the difference of technology, there is several different installation site, as shown in Figure 1.
These installation methods respectively have relative merits.But owing to being flooded with space between pyrometer and radiation grog by auxiliary air from the dust that cooler brings, reduce the radiation arriving pyrometer, result in temperature indicating value and forbidden.In addition, can there is certain drift in kiln flame, also can bring obvious impact to the measurement of pyrometer.Finally, when rotary kiln overhauls, kiln head cover needs to open and as transport channel, this is easy to the damage causing measuring instrument attached thereto.
Summary of the invention
In order to solve the above-mentioned difficult problem existed in prior art, the utility model provides a kind of novel rotary kiln clinker temperature infrared temperature measurer device, and effectively can avoid the interference of dust and flame in kiln, measuring accuracy is high, can meet daily production and application.Its technical scheme is as follows:
A kind of rotary kiln clinker temperature infrared measuring instrument device, comprise quartz window and Infrared survey instrument, described quartz window is arranged on the side of kiln head cover, and the infrared light path measurement point of described Infrared survey instrument is positioned at the rotary kiln outlet grog droping space middle with kiln head cover.
Further, described Infrared survey instrument is fixed on outside described quartz window.
Further, described quartz window, by kiln head cover perforate extraction channel, is installed quartz glass in channel outlet and is formed.
Further, the inclination angle of the light path measuring center line that aims at through quartz window of described Infrared survey instrument and surface level is between 20-60 °.
Further, described quartz window length and width scope is 10-20cm.
Rotary kiln clinker temperature infrared measuring instrument device of the present utility model mainly contains two advantages: first, optical path airborne dust is few, does not also have flame, and therefore the precision of measuring tempeature is very high; Secondly, measurement instrument integral installation, in kiln head cover side, does not account for access path, and therefore impaired probability is very low.
Accompanying drawing explanation
Fig. 1 is traditional infrared measuring instrument scheme of installation;
Fig. 2 is Infrared survey instrument installation site, kiln head cover side of the present utility model schematic diagram;
Fig. 3 is kiln head cover A-A sectional view.
Embodiment
Embodiment of the present utility model is further described below in conjunction with accompanying drawing.
As shown in Figures 2 and 3, rotary kiln clinker temperature infrared measuring instrument device of the present utility model, it comprises: quartz window 1, Infrared survey instrument 2, described quartz window 1 is arranged on the side of kiln head cover, and the infrared light path measurement point of Infrared survey instrument 2 is be positioned at the rotary kiln outlet grog droping space middle with kiln head cover.
Perforate on kiln head cover side, central point of hole and rotary kiln discharging point are positioned at same level position, and central point distance infrared light path measurement point height is 1-3 rice, for installing quartz glass.The length and width scope in hole is 15-30cm.
Described Infrared survey instrument 2 is installed in quartz window 1 outside, and Infrared survey instrument 2 and horizontal inclination angle are between 20-60 °, and described quartz window 1 length and width scope is 10-20cm.
