Abstract
The utility model discloses an asphalt mixing station roller discharge chute, which comprises a chute body. The side wall of the chute body is provided with an infrared temperature measuring instrument. The infrared temperature measuring instrument is arranged inside a protective casing. The protective casing is fixedly connected with a bearer of the protective casing. The bearer and the side wall are at an included angle less than 90 DEG. The bearer is connected on the side wall of the discharge chute and communicated with the inner side of the chute body. The bearer and the side wall are at an included angle less than 90 DEG. Therefore, aggregate inside the discharge chute is prevented from impacting on the temperature measuring instrument along the bearer. The circular-face areas of infrared rays are slightly increased due to the fact that the bearer and the side wall are at an included angle less than 90 DEG. Dust inside the bearer inner hole has little interference in the temperature measuring precision. The interference is within a tolerable range.
Description
Technical field
The present invention relates to a kind of asphalt mixing plant cylinder blowpit.
Background technology
The infrared thermometer of take at present is good for the infrared temperature-test technology growth momentum mainly represented.The infrared thermometer chief component is: optical system, photodetector, signal amplifier and signal processing circuit, demonstration output unit.Wherein, optical system can converge the Target Infrared Radiation energy in its visual field, and the size of visual field is by the optical element of temperature measurer and location positioning thereof.Infrared energy focuses on photodetector and changes corresponding electric signal into.Electric signal is through the processing of signal amplifier and signal processing circuit, and the default algorithm according to instrument internal, after being proofreaied and correct with the target emissivity, finally change the actual temperature value of measured target into.But the infrared thermometer precision is subject to dust impact in environment.
Cylinder blowpit place aggregate to asphalt mixing plant carries out temperature survey, compare traditional thermoelectricity and say occasionally, infrared thermometer has its unique advantage, and mainly comprise following 4 points: 1) life-span is long, because adopting contactless temperature-measuring, do not exist by the problem of sandstone impact wear.2) thermal response is rapid, and the fastest 500mS response time just can stablize to 200 ℃.3) adopt two-wire system 24VDC power supply, synchronous signal is by outputting standard 4-20mA signal voluntarily in infrared thermometer.4) parameter is manually adjustable, can carry out configuration programming and fault diagnosis to it, easy to maintenance quick.
The advantage possessed just because of infrared thermometer, asphalt mixing plant cylinder blowpit place is used infrared thermometer more at present.Infrared thermometer vertical ground of the prior art is installed, and by containment vessel and bearing, is fixed on the blowpit upper wall and the blowpit internal communication, and temperature measurer probe place carries the back-blowing interface.
Owing to often being mixed with a large amount of dust in aggregate, aggregate falls along the blowpit lower wall, material fluid layer thickness is the 100mm left and right, a large amount of dust are filled the air on material stream upper strata, the about 250mm of dust bed thickness, prior art is only to rely on the back-blowing interface to be blown into purification wind to reduce local dust concentration, without other processing modes.But in actual use, because dust layer is blocked up, the groove internal gas pressure is larger, inverse blowing device only can guarantee before the temperature measurer camera lens in barotropic state, be attached on camera lens without dust, and to dust concentration without effective reducing effect.
Existing infrared thermometer mounting means and actual condition make infrared ray need vertically through thicker dust layer, just can record the temperature value of aggregate.High concentrate dust makes infrared ray loss of signal in two-way process larger, makes the temperature value finally recorded more on the low side than aggregate actual temperature value, and in actual production, test finds that measured value is than actual value about 10-20 ℃ on the low side.
The problems referred to above cause for making the infrared thermometry apparatus measuring value reach goal-setting value level, and the aggregate temperature of cylinder heating surpasses setting value, and subsequent production is caused to harmful effect.
Summary of the invention
The objective of the invention is for existing technical matters, a kind of asphalt mixing plant cylinder blowpit is provided, can effectively reduce the impact of blowpit place dust on measuring accuracy.
For achieving the above object, the invention provides a kind of asphalt mixing plant cylinder blowpit, this device comprises:
Comprise cell body; the sidewall of described cell body is equipped with infrared thermometer, and described infrared thermometer is arranged in containment vessel, and containment vessel is fixedly connected with its bearing; bearing is connected on blowpit sidewall 5 and the cell body internal communication, and described bearing and sidewall form non-90 ° of inclination angles.
[0010]as further improvement, described infrared thermometry instrument probe place carries the back-blowing interface, and the back-blowing interface connects gas circuit, guarantees camera lens the place ahead malleation, adheres to without dust.
Preferably, described containment vessel with its bearing by flange, screw, bolt is fixed or bayonet socket mode and bearing are fixed together, can better be fixedly connected with.
[0012]the beneficial effects of the utility model: hot aggregate falls along the blowpit diapire, the installation site of bearing makes the infrared ray of infrared thermometer emission just to drop on aggregate, and do not need through the upper strata dust layer, thereby greatly reduce the interference of dust to signal.Because bearing and sidewall are less than 90 ° of angles, guaranteed that in blowpit, aggregate can be along impacting temperature measurer in bearing.Be less than 90 ° of angles between bearing and sidewall and make ultrared disc area slightly increase, the dust in the bearing endoporus slightly has enhancing to the interference of temperature measurement accuracy.
the accompanying drawing explanation
Fig. 1 is the utility model structural representation;
The A that Fig. 2 is Fig. 1 is to view.
embodiment
As shown in Figure 2, a kind of asphalt mixing plant cylinder blowpit, comprise cell body, the sidewall 5 of cell body is equipped with infrared thermometer, described infrared thermometer is arranged in containment vessel 1, containment vessel 1 is fixedly connected with by flange with its bearing 3, can certainly be to screw, bolt is fixed or bayonet socket mode and bearing 3 are fixed together, bearing 3 is connected on blowpit sidewall 5 and the cell body internal communication, with diapire 6 apart from 48mm, bearing 3 has 15 ° of inclination angles with diapire 6, certainly this inclination angle can be also 1 °, 10 °, 30 °, 50 °, 70 °, 89 °, with sidewall 5,75 ° of inclination angles are arranged, certainly this inclination angle can be also 1 °, 12 °, 35 °, 50 °, 70 °, 89 °, bearing 3 all meets the application's requirement with the inclination angle that sidewall 5 and diapire 6 form so long as not right angle, described infrared thermometry instrument probe place carries back-blowing interface 2, back-blowing interface 2 connects gas circuit.
Above-described embodiment of the present utility model is only the invention for clearly illustrating that the utility model is done, and is not the restriction to embodiment of the present utility model.Variation or the change of all other different structure forms of making on the basis of the above description, belong to the amplification to design of the present utility model, still among this uses novel protection domain.
