Description
Technical field
The utility model relates to the device that a kind of novel portable waste oil detects.
Background technology
In recent years, all parts of the country occur that lawless person collects food and beverage waste oil and grease, after processing is processed, with knockout price, sell the behavior of seeking exorbitant profit in eating house, grease workshop.The waste oil that current China returns to dining table every year has 2,000,000 to 3,000,000 tons.
External because discarded oil product is carried out to policy recovery to be transformed, substantially do not have waste oil to enter the phenomenon of dining table.And existing domestic experimental technique is confined to laboratory stage, limit greatlyr, and society is larger to the demand of portable, family detecting device, so present stage still lacks, is by the method for checkout equipment portability.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of have portable, detect fast and detect accurate feature, can solve the device that the novel portable waste oil of problem of the real-time portable inspectiont of waste oil detects.
The utility model is achieved through the following technical solutions: the device that a kind of novel portable waste oil of the present utility model detects, described device comprises light source, oil samples to be measured, corrected oil sample, photoelectric commutator, differential amplifier, hysteresis loop comparator and pilot lamp alarm, described light source comprises light source one and light source two, described photoelectric commutator comprises photoelectric commutator one and photoelectric commutator two, described light source one is connected with oil samples to be measured, described oil samples to be measured is connected with photoelectric commutator one, described light source two is connected with corrected oil sample, described corrected oil sample is connected with photoelectric commutator two, described photoelectric commutator one is all connected with differential amplifier with light source converter two, described differential amplifier is connected with hysteresis loop comparator, described hysteresis loop comparator is connected with pilot lamp alarm.
Further technical scheme, described light source is LED lamp.
The beneficial effects of the utility model are: in actual household portable detects, whole testing circuit is a portable instrument by being integrated into, after only needing to put into sample, opening power can detect, the utlity model has portable, detect fast and detect accurate feature.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the block diagram of the device of a kind of novel portable waste oil detection of the present utility model;
Fig. 2 is the circuit diagram of the device that detects of a kind of novel portable waste oil of utility model.
Embodiment
As shown in Figure 1, the device that a kind of novel portable waste oil of the present utility model detects, described device comprises light source, oil samples to be measured, corrected oil sample, photoelectric commutator, differential amplifier, hysteresis loop comparator and pilot lamp alarm, described light source comprises light source one and light source two, described photoelectric commutator comprises photoelectric commutator one and photoelectric commutator two, described light source one is connected with oil samples to be measured, described oil samples to be measured is connected with photoelectric commutator one, described light source two is connected with corrected oil sample, described corrected oil sample is connected with photoelectric commutator two, described photoelectric commutator one is all connected with differential amplifier with light source converter two, described differential amplifier is connected with hysteresis loop comparator, described hysteresis loop comparator is connected with pilot lamp alarm.
A kind of optimal way of the present utility model, described light source is LED lamp.
As shown in Figure 2, light is irradiated on PIN pipe, will produce photocurrent, by the characteristic of triode, can be drawn, the voltage on R3 is the resistance that the photocurrent of PIN pipe is multiplied by R1.The function of left half circuit is that light signal is converted to electric signal, and the function of right-hand component circuit is amplification signal, and meanwhile, R4 is variable resistor, has the effect of real-time zeroing.
The two-beam line that light source one and light source two produce enters respectively oil samples to be measured and corrected oil sample, then light enters photoelectric commutator and completes light signal and be converted to current signal and be finally converted to voltage signal and signal and amplify, two signals are contrasted in comparer simultaneously, in the time of in the threshold range that correlative value is not being set, pilot lamp alarm equipment alarm.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
Claims (2)
1. the device that a novel portable waste oil detects, it is characterized in that: described device comprises light source, oil samples to be measured, corrected oil sample, photoelectric commutator, differential amplifier, hysteresis loop comparator and pilot lamp alarm, described light source comprises light source one and light source two, described photoelectric commutator comprises photoelectric commutator one and photoelectric commutator two, described light source one is connected with oil samples to be measured, described oil samples to be measured is connected with photoelectric commutator one, described light source two is connected with corrected oil sample, described corrected oil sample is connected with photoelectric commutator two, described photoelectric commutator one is all connected with differential amplifier with light source converter two, described differential amplifier is connected with hysteresis loop comparator, described hysteresis loop comparator is connected with pilot lamp alarm.
