[0035] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0036] See Figure 1-2 as shown;

[0037] A rapid detector for desulfurization liquid components according to an embodiment of the present utility model includes:

[0038] An optical wave emitting device 10, the optical wave emitting device 10 includes a substrate 11 and a diode 12 connected thereto. The optical wave emitted by the diode 12 is transmitted to a filter device 14 through an optical wave conduction device 13. The optical wave filtered by the filter device 14 is transmitted to a plurality of colorimetric cuvettes in a colorimetric cell 15, and the plurality of colorimetric cuvettes absorb the light intensity of the received optical wave; the filter system selects the required wavelength according to the specific detection parameters of the user under the control of the control system. The filter device 14 is a spectroscopic system including a filter and / or a prism and / or a grating, and then the optical wave of the required wavelength is selectively transmitted through the slit;

[0039] A photoelectric detection device 20, the photoelectric detection device 20 collects the color change progress information of the solution in the colorimetric cuvette and outputs the collected color change progress information as an analog signal;

[0040] A photoelectric analog-to-digital conversion module 30, the photoelectric analog-to-digital conversion module 30 receives the analog signal output by the photoelectric detection device 20 and converts it into a digital signal;

[0041] A calculation unit 40, the calculation unit 40 calculates the absorbance of the digital signal received from the output of the photoelectric analog-to-digital conversion module 30, and calculates the detection result based on the calculated absorbance;

[0042] A controller 50, the controller 50 receives the calculation detection result of the calculation unit 40 and displays it through a display unit 60. The display unit 60 can also perform human-computer interaction with the user. The controller 50 can control the on / off and light intensity of the diode 12 of the optical wave emitting device 10. The controller 50 can control the filter device 14 of the optical wave emitting device 10 to select the wavelength parameter required for the sample to be measured.

[0043] A microlens 16 is provided between the diode 12 and the optical wave conduction device 13.

[0044] The optical wave emitting device 10 further includes a detector 17 and a photoelectric detection circuit 18. The detector 17 detects the optical wave intensity in the colorimetric cuvette and transmits the optical wave intensity to the photoelectric detection circuit 18. The photoelectric detection circuit 18 determines whether there is a fault in the light emission intensity of the diode 12 according to the optical wave intensity, and the photoelectric detection circuit 18 transmits the determination information to the controller 50 through the substrate 11.

[0045] The filter device 14 internally incorporates multiple detection parameters, each with a specific detection wavelength. The customer selects the detection parameters through the display unit 60, and after selection, the controller 50 sends an operation instruction to the filter device 14. When the filter device 14 is composed of filter plates, the filter plates with multiple detection wavelengths are fixed on a circular filter disc. A high-precision stepper motor is installed at the center of the filter disc. When the filter device 14 receives an instruction for a specified detection wavelength, it controls the stepper motor to rotate the required filter plate to the optical path to achieve the filtering effect. When the filter device 14 is composed of a prism and / or a grating and a slit, a stepper motor is installed at the bottom of the prism or the grating. When incident light enters the prism or the grating, it will be dispersed into a spectrum. When the filter device 14 receives an instruction for a specified detection wavelength, it controls the stepper motor to rotate the prism or the grating to a specified position, and passes the light of the detection wavelength to be measured through the slit to achieve the filtering effect.

[0046] The colorimetric cell 15 is made of an opaque black anti-corrosive polymer polypropylene material. A layer of light transmission isolation film is respectively provided between the colorimetric cell 15 and the filter device 14 and the detector 17 for physical isolation between the colorimetric cell 15 and the detector 17, the filter plate and / or the prism and / or the grating, to prevent the leakage of the colorimetric dish in the colorimetric cell 15 from damaging the circuit and the light wave emitting device 10.

[0048] The photoelectric detection device 20 is a camera. The controller 50 sends an instruction to the camera, and the camera takes pictures of the solution in the colorimetric dish for collection. The intensity of the transmitted light in the collected image is evaluated through another photoelectric detection circuit, and the detected transmitted light intensity is sent to the photoelectric analog-to-digital conversion module 30 as an analog signal. The photoelectric detection device 20 is a photosensitive detection component, which is a semiconductor device that directly converts light energy into electrical energy through its built-in silicon photocell. According to the photovoltaic effect, when light irradiates the semiconductor PN junction on the surface of the silicon photocell, internal electrons transition to form an electromotive force at both ends of the cell. The stronger the light intensity, the greater the electromotive force. The light intensity is released as this virtual signal of electromotive force, and the detected transmitted light intensity is sent to the photoelectric analog-to-digital conversion module 30 as an analog signal.

[0049] The optoelectronic digital-to-analog conversion module 30 is a circuit that converts analog signals into digital signals. It includes a digital-to-analog conversion D / A, an operational amplifier, a reference power supply, and an analog switch. When the digital-to-analog conversion module 30 receives an analog signal, the signal first enters the digital-to-analog conversion D / A. One pulse in the analog quantity is equivalent to one unit in the digital quantity. By adding up all the analog quantities, a digital quantity proportional to it is obtained, usually the electric potential V. This digital quantity is transmitted to the operational amplifier. Since the digital quantity transmitted by the D / A at this time is too low to be directly calculated, the operational amplifier is responsible for expanding the received digital quantity by a corresponding multiple for the calculation unit to recognize. At the same time, the reference power supply provides electrical energy for the D / A and the operational amplifier. The analog switch is responsible for the operation and stop of the digital-to-analog conversion module 30 under the instruction of the control system; the optoelectronic digital-to-analog conversion module 30 can select the ADI Analog Devices package SOP16, model: AD7400AYRWZ-RL. The optoelectronic digital-to-analog conversion module 30 is responsible for converting the analog signal representing the transmitted light intensity detected by the optoelectronic detection device 20 into a digital signal that can be recognized by the calculation unit 40. The calculation unit 40 uses the Lambert-Beer law to obtain the concentration of the substance to be detected in the sample through absorbance.

[0050] The controller transmits the obtained detection result to the display unit 60. The display unit can select a display. The user inputs information related to the test sample into the controller 50 by means of screen touch and / or physical buttons on the display screen. The controller 50 makes a record; the display unit 60 also receives the detection result transmitted by the controller 50, pairs and displays the detection result with the corresponding sample number and saves it in the record.

[0051] The controller 50 transmits the received calculated detection result to the Internet of Things database 71 and the client 72 through the communication module 70. The client 72 is a smart phone and a computer, and can remotely view the detection result.

[0052] The rapid detector of this application can greatly reduce the manual operation error, shorten the detection time, upload data in a timely manner, and can view the detection result in real time on different clients through simple and easy-to-learn experimental operations.
