Description
(1) technical field
The utility model relates to the detection system technical field, relates in particular to a kind of superheated vapor environment hot metal detector.
(2) background technology
Traditional hot metal detector is harsh relatively to environment requirement, if testing environment has smog or steam etc. to hinder the material of light ray propagation, the precision that then detects will receive bigger influence.The working environment of at present general hot metal detector can allow the existence of certain steam, dust or smog etc., if but concentration is higher, and the accuracy of detection of detecting device and the degree of reliability will receive great influence.Make the relevant device cisco unity malfunction, bring very big limitation to production run.The utility model relates to a kind of measurement mechanism that can be under the superheated vapor environment still can be effectively the position of high-temperature metal, speed, acceleration etc. be detected; It can be sent to host computer or master control set with the signal that detects gained, so that host computer or master control set calculate and control corresponding according to the signal that this detecting device sended over.Compared with traditional hot metal detector, the utility model can be accomplished the detection task to thermometal more reliably under the environment of superheated vapor or smog.
(3) utility model content
The purpose of the utility model provides a kind of hot metal detector that can influence reliably working under the occasion that infrared light propagates at steam, dust or the smog etc. of higher concentration.Hot metal detector generally is applicable to the detection of hot-strip, comprises steel rolling mill's control shearer, control roll bed, regulating winding and monitoring hot rod etc.Keep watch on casting cycle, control position and supervision travelling belt etc. at the forging and pressing casting industry.In a word; In office what is the need for will utilize infrared radiation to carry out the place of respective detection, can use hot metal detector, still; If the concentration of the steam in the working environment of detecting device, dust or smog etc. is higher, traditional hot metal detector can't use.The utility model can be worked in steam, dust or the higher occasion of smog isoconcentration reliably, promptly the position of high-temperature metal, speed, acceleration etc. is detected.The purpose of the utility model is achieved in that
A kind of superheated vapor environment hot metal detector; Comprise the waterproof washer at front end end cover, Circular glass sheet, optical filtering, baffle plate, sleeve, O-ring seal, the treatment circuit plate that the infrared probe process chip is housed, rear end cap place, the watertight connector screw thread, rear end cap, the circular shell that are positioned at rear end cap central authorities and the bolt that is used for fixing front and rear cover; Between said baffle plate and the infrared probe; All scribble the coating of black on the shell circular inner wall with around the infrared probe, the coating of this black can absorb the light of various wavelength.
Beneficial effect: this detecting device mainly is used for detecting the high-temperature metal under the environment such as superheated vapor, dust and smog in high concentration.Be used to forge and the metal of hot rolling etc. generally can reach more than 1200 ℃ in the temperature that is about to before processed; The metal of this temperature can send the IR of a large amount of wavelength greater than 950nm; And in available light; Wavelength is greater than the content of the infrared light of 950nm and faint, so, can come the indirect detection high-temperature metal through detecting the infrared light of wavelength in this scope.The optical filter of this detecting device front can the filtering wavelength less than the light of 950nm; Only allow wavelength to pass through more than or equal to the light of 950nm; And inner infrared probe is the light the most responsive (sensitivity curve is seen accompanying drawing 2) about 950nm to wavelength; When probe receives wavelength when being the light about 950nm, the signal of probe output is the strongest, the amplifying circuit and process chip processing through high-amplification-factor successively with this signal; The watertight connector of the signal of handling through this detecting device rear portion spread out of, be connected to the perhaps corresponding main control equipment of host computer and handle.The front distance measured workpiece of this detecting device can reach 10cm apart from minimum, to guarantee having wavelength as much as possible can inject detecting device greater than the IR of 950nm.Near with the measured workpiece distance based on this detecting device, enlargement factor is high, and to detecting the pointed advantage of light wavelength scope, through experiment, this sensor can be worked under the very big situation of steam, dust or smog isoconcentration reliably.

(5) embodiment
As shown in Figure 1, this sensor is made up of the waterproof washer 1 at front end end cover 8, optical filtering 9, Circular glass sheet 10, baffle plate 11, sleeve 12, O-ring seal 13, the treatment circuit plate 15 that infrared probe 5 process chip 4 etc. are housed, rear end cap 3 places, the bolt that is positioned at watertight connector screw thread 2, rear end cap 3, the circular shell 14 of rear end cap 3 central authorities and is used for fixing front and rear cover.The duty of this detecting device such as Fig. 2, shown in Figure 3; The tested IR that high-temperature metal sent passes Circular glass sheet 10, optical filtering 9 and center has baffle plate 11 backs of a through hole to be received by infrared probe 5; Between baffle plate 11 and infrared probe 5; On the circular inner wall of shell and infrared probe 5 around all scribble the coating 6 of black as shown in Figure 1; This black coating 6 can absorb the light of various wavelength, and such structure can guarantee that infrared probe 5 receives only the light from measured workpiece in the dotted portion scope in the accompanying drawing 3.Have only like this when measured workpiece is immersed in the zone that diameter in the accompanying drawing 3 is d; Could be detected by this detecting device; And different according to the distance between measured workpiece and detecting device, the size of d also can change, when the fixed distance of detecting device and measured workpiece; The size that also can adjust through-hole diameter on the baffle plate 11 is adjusted the size of d, thus the measurement range of adjustment detecting device.As shown in Figure 1; Because the influence of steam, dust or smog etc.; Infrared probe possibly receive only the IR of very faint wavelength greater than 950nm; But this infrared probe is that infrared light about 950nm is the most responsive to wavelength, and bigger signal output can be arranged, and this signal passes through the amplifying circuit of high-amplification-factor again; Through a kind of distinctive signal that is different from other wavelength region may light that is treated as of the peculiar algorithm of process chip, this signal arrives host computer or main control equipment through cable transmission more again.
In sum: superheated vapor environment hot metal detector is through detecting the infrared light that measured workpiece sent in certain sensing range; With the circuit of the faint signal process high-amplification-factor that detects gained and processing with process chip of special algorithm; Under working environment with high concentration steam, dust or smog etc.; The infrared signal of unique wave band that measured workpiece sent is converted into host computer or the receptible digital signal of main control equipment, thereby has realized under working environment detection thermometal with high concentration steam, dust or smog etc.
