[0021] The purpose of this application is to overcome the above-mentioned technical deficiencies, propose an automated methylene blue value detection system and detection method, and solve the technical problems of low detection efficiency and insufficient detection accuracy in the prior art.

[0022] In order to achieve the above technical objectives, this application adopts the following technical solutions: In the first aspect, the present application provides an automated methylene blue value detection system, such as Figure 1 and Figure 2 As shown, Figure 1 Schematic diagram of the structure of an automated methylene blue value detection system provided in an embodiment of the present application; Figure 2 It is a top view schematic diagram of an automated methylene blue value detection system provided in an embodiment of the present application.

[0023] An automated methylene blue value detection system includes an experimental container 1, a preparation module, a robot 5, a tool module, a visual detection device 9, and a control device: Experimental container 1; A preparation module, the preparation module comprises a feeding device 2, a water tank 3 and a methylene blue solution dispenser 6, the feeding device 2, the water tank 3 and the methylene blue solution dispenser 6 are all facing the experimental container 1; The robot 5 is spaced apart from the experimental container 1; A tool module, the tool module comprises a stirring device 4 and a sampling device, the stirring device 4 and the sampling device are distributed around the robot 5; a visual inspection device 9, facing the sampling device; and The control device is signal-connected with the feeding device 2, the stirring device 4, the robot 5, and the visual detection device 9 respectively.

[0024] The present application drives the feeding device 2 and the stirring device 4 by the control device to reduce external interference. In the traditional method, the dropping and stirring process of the methylene blue solution are susceptible to human operation and the influence of the external environment, resulting in deviations in the test results. The automation scheme reduces the errors caused by improper human operation by optimizing the equipment design and operation process, and improves the accuracy of the test results. By controlling the device to drive the robot 5 and the visual inspection device 9, the steps of sampling, adding methylene blue solution, stirring, and visual inspection can be automatically completed without manual intervention, thereby improving the convenience of operation. The detection scheme realizes the rapid detection of methylene blue values ​​by optimizing the detection process and equipment performance, thereby improving the detection efficiency. The automated detection equipment has the ability to continuously detect and can complete the detection work of multiple samples in a short time, further improving the detection efficiency.

[0025] The experimental container 1 is placed in the detection system, and the feeding device 2 is ready to feed the sample to be tested into the experimental container 1.

[0026] The control device activates the feeding device 2 to accurately feed the sample to be tested into the experimental container 1.

[0027] The control device starts the stirring device 4 to ensure that the sample is evenly mixed in the experimental container 1 to prepare for the next detection step.

[0028] According to the instruction of the control device, the robot 5 uses the dipping rod 7 to absorb the methylene blue solution in the methylene blue solution dispenser 6 and drips the methylene blue solution onto the sample in the experimental container 1 .

[0029] The methylene blue solution reacts with the sample and the color change indicates the methylene blue value.

[0030] The visual detection device 9 captures and analyzes the color change on the test paper 8 and transmits the data to the control device.

[0031] The control device calculates the methylene blue value based on the data provided by the visual detection device 9 and outputs the result.

[0032] The automated process reduces human error and ensures the accuracy of the test results. The automated system can operate continuously, significantly reducing the time required for testing a single sample, thereby improving overall work efficiency. The entire testing process does not require human intervention, is easy to operate, and reduces the operator's skill requirements. By precisely controlling each step, the standardization and optimization of the testing process is achieved. All test data can be recorded and analyzed for subsequent data tracking and quality control.

[0033] In some embodiments of the present application, a waste container 10 is further included, which is spaced apart from the experimental container 1. The feeding device 2 includes a three-way feeding pipe, and the three-way feeding pipe includes a feeding port, a first discharge port 12, and a second discharge port 13. The first discharge port 12 and the second discharge port 13 are respectively facing the experimental container 1 and the waste container 10.

[0034] The feeding device 2 introduces the sample to be tested into the three-way feeding pipe through the feeding port.

[0035] First discharge port 12: The control device delivers an appropriate amount of sample from the first discharge port 12 into the experimental container 1 through the control valve of the three-way feed pipe according to a preset program to perform methylene blue value detection.

[0036] Second discharge port 13 : Meanwhile, excess sample or unnecessary sample is guided to the waste container 10 through the second discharge port 13 .

[0037] In the test container 1, the sample is mixed with the methylene blue solution and stirred by the stirring device 4, followed by visual inspection or other forms of inspection.

[0038] The waste container 10 collects waste discharged from the second discharge port 13 , and the waste may include unreacted samples, cleaning fluids or other unnecessary substances.

[0039] The entire process is managed by a control device to ensure accurate distribution of samples and proper disposal of waste.

[0040] The design of the three-way feed tube allows precise control of the flow and direction of the sample, reduces errors, and improves detection accuracy. Automatic distribution of samples to the experimental container 1 and the waste container 10 reduces manual operation steps and improves detection efficiency. Through physical isolation, samples and waste are discharged through different outlets, reducing the risk of cross contamination.

[0041] In some embodiments of the present application, the feeding device 2 also includes a weighing component and a telescopic cover, the weighing component carries the three-way feeding pipe, the telescopic cover covers the first discharge port 12, and the weighing component and the telescopic cover are both connected to the control device signal.

[0042] The weighing assembly carries the three-way feed pipe and is used to weigh the sample in real time during the feeding process. When the sample enters the three-way feed pipe through the feed port, the weighing assembly immediately starts measuring and transmits the weight data to the control device in real time.

[0043] The telescopic cover covers the first discharge port 12 and can be opened or closed under the instruction of the control device to control the flow direction of the sample.

[0044] After the weighing is completed, the control device instructs the telescopic cover to open according to preset parameters, allowing the sample to flow into the experimental container 1.

[0045] The control device accurately controls the distribution amount of the sample according to the data provided by the weighing component.

[0046] When the preset weight is reached, the control device closes the feed port and introduces the sample into the experimental container 1 through the telescopic cover.

[0047] Excess sample or unnecessary sample is guided to the waste container 10 through the second discharge port 13 .

[0048] The use of the weighing assembly ensures accurate measurement of the sample weight, thereby improving the accuracy of the test. The weighing assembly and the telescopic cover are both connected to the control device signal, which realizes the automation of sample distribution and reduces human errors. Through the control device, the sample distribution amount can be easily adjusted to meet different experimental needs.

[0049] In some embodiments of the present application, the experimental container 1 has an upward opening, and the first discharge port 12 of the feeding device 2, the water outlet 14 of the water tank 3, and the liquid outlet of the methylene blue solution dispenser 6 face the opening.

[0050] The experimental container 1 has an opening facing upward, so that operations such as adding samples, reagents or stirring can be conveniently performed from above.

[0051] When the first discharge port 12 of the feeding device 2 faces the opening of the experimental container 1 , the sample can be accurately fed into the experimental container 1 through the three-way feeding tube.

[0052] The control device instructs the feeding device 2 to inject an appropriate amount of sample into the experimental container 1 through the first discharge port 12 according to the experimental requirements.

[0053] The water outlet 14 of the water tank 3 also faces the opening of the experimental container 1, and is used to add water or other liquids into the experimental container 1 when necessary to perform operations such as dilution or cleaning of the sample.

[0054] The liquid outlet of the methylene blue solution dispenser 6 is also oriented toward the opening of the experimental container 1 , ensuring that the methylene blue solution can be accurately added to the sample in the experimental container 1 .

[0055] The whole process is automatically controlled by the control device, including the addition of samples, dilution of water, addition of methylene blue solution, etc., which reduces manual operations and improves the repeatability and accuracy of the experiment.

[0056] In some embodiments of the present application, the stirring device 4 includes a rotating motor, a stirring impeller and a lifting assembly, the lifting assembly is connected to the rotating motor, the output shaft of the rotating motor is connected to the stirring impeller, the stirring impeller is located above the opening of the experimental container 1, and the rotating motor and the lifting assembly are both connected to the control device signal.

[0057] Rotary motor: provides power to drive the stirring impeller to rotate.

[0058] Stirring impeller: directly contacts the sample and achieves stirring through rotation.

[0059] Lifting assembly: used to adjust the height of the stirring impeller so that it can be accurately located above the opening of the experimental container 1.

[0060] When the sample in the experimental container 1 needs to be stirred, the control device connects the lifting assembly through a signal to adjust the height of the stirring impeller to ensure that it is lowered into the experimental container 1 and submerged in the solution. At the same time, the control device sends a signal to the rotating motor, which starts and drives the stirring impeller to rotate.

[0061] The entire stirring process is automatically controlled by the control device, including the stirring speed, stirring time and the lifting position of the stirring impeller.

[0062] The control device allows precise adjustment of stirring speed and time to ensure uniform mixing of the sample.

[0063] The use of the lifting assembly enables the stirring impeller to adapt to experimental containers 1 of different heights, thereby increasing the flexibility of the device.

[0064] In some embodiments of the present application, the robot 5 includes a robotic arm and a suction cup, the sampling device includes a dipping rod 7 and a test paper 8, the robotic arm is transmission-connected to the suction cup, the suction cup is adsorbed and connected to the test paper 8 or the dipping rod 7, and the robotic arm is signal-connected to the control device.

[0065] Robotic arm: used to accurately move and position the test paper 8 or the dip stick 7.

[0066] Suction cup: It generates negative pressure to absorb the test paper 8 or the dip stick 7, so that it can be manipulated by the robot arm.

[0067] When sample processing or testing is required, the control device sends a signal to the robotic arm to drive the robotic arm to move to the storage position of the test paper 8 or the dipping stick 7.

[0068] The suction cup generates suction under the command of the control device to absorb the test paper 8 or the dipping stick 7.

[0069] According to a preset program, the robot arm moves the adsorbed test paper 8 or the dipping stick 7 to the top of the experimental container 1 to perform operations such as sampling or adding reagents.

[0070] After the operation is completed, the suction cup releases the suction force and the test paper 8 or the dipping stick 7 is placed back to its original position or into the waste container 10.

[0071] The robot arm can accurately control the position and movement of the test paper 8 or the dipping stick 7 to reduce human error.

[0072] The entire operation process is automatically controlled by the control device without manual intervention, which improves the automation of the experiment. The robotic arm can be programmed to perform a variety of different operation tasks to meet different experimental needs.

[0073] In a second aspect, the present application also provides an automated methylene blue value detection method, such as Figure 3 and Figure 4 As shown, Figure 3 This is a flow chart of an automated methylene blue value detection method provided in an embodiment of the present application; Figure 4 This is a workflow diagram of an automated methylene blue value detection system provided in an embodiment of the present application.

[0074] An automated methylene blue value detection method, using the automated methylene blue value detection system as described in any one of the embodiments of the first aspect, comprising the following steps: S1. Add a preset weight of sample to the experimental container 1; S2. Add a preset volume of distilled water to the experimental container 1 and stir the experimental container 1; S3. Add methylene blue solution to the experimental container 1, take a sample and stain the test paper 8; S4. Detect the test paper 8, record the mass of the sample added, the volume of the distilled water, the parameters of the methylene blue solution; S5. Calculate the methylene blue value.

[0075] Specifically, 1) open the feed port and add the dried and sieved sample, weigh 200g with the electronic scale under the experimental container 1, then close the feed port, and pour the remaining sample into the waste container 10. There are two feed ports, which are respectively aimed at the experimental container 1 and the waste container 10. When feeding, open the feed port on one side of the experimental container 1, close the feed port after completion, open the feed port on one side of the waste container 10, and pour the excess sample into the waste container 10.

[0076] 2) Add 500±5mL of distilled water by controlling the opening and closing time of the valve, and use an electronic scale to weigh the total mass to obtain the actual volume of distilled water added. The error can be eliminated by calculation. The water tank 3 is used to store distilled water on the top of the whole machine. You only need to add enough distilled water to the water tank 3 regularly; 3) The stirring impeller of the stirring device 4 descends into the container, starts stirring at a speed of 600±60r / min for 5 minutes, and then switches to 400±40r / min; 4) The robot 5 uses the suction cup to pick up a test paper 8 and places it on the beaker; 5) The robot 5 controls the methylene blue solution dispenser 6 to add 5 mL of methylene blue solution through the end suction cup and continues stirring for one minute; 6) The robot 5 sucks the top of the dip stick through the suction cup, moves to the experimental container 1, dips the surface suspension, and drops it onto the test paper 8. After completion, the dip stick is placed on the shelf for standby use; 7) Use a camera to detect whether there is an obvious color halo around the precipitate, and calculate the MB value based on the total volume V of the added methylene blue solution and the mass G of the sample.

[0077] Methylene blue MB value calculation (accurate to 0.01):

[0078] In the formula: MB is the methylene blue value, in grams per kilogram (g / kg), which means the mass of methylene blue consumed per kilogram of 0mm-2.36mm particle size sample; G is the mass of the sample, in grams (g); V is the total amount of methylene blue solution added, in milliliters (mL); 10 is the volume of methylene blue solution consumed per kilogram of sample converted into the mass of methylene blue.

[0079] This involves the problem of unit conversion, and the above formula can be rewritten as:

[0080] Let M = 10*V, that is, each liter of methylene blue solution contains 10g of methylene blue powder, and the mass of methylene blue powder contained in V(L) methylene blue solution is M(g), then:

[0081] That is, 10g of methylene blue powder is prepared with 1000mL of methylene blue solution, and the corresponding dry powder mass M can be calculated by the added methylene blue solution volume V. Dividing M by G can give the mass of methylene blue powder consumed per kilogram of sample, that is, the MB value.

[0082] In some embodiments of the present application, the testing of the test paper 8, recording the mass of the added sample, the volume of the distilled water, and the parameters of the methylene blue solution, includes: Detecting whether a color halo appears on the test paper 8; If it does not appear, repeatedly add the methylene blue solution and stir, take a sample and stain the test paper 8 until a color halo appears on the test paper 8.

[0083] Specifically, use the camera to detect whether there is an obvious color halo around the precipitate. If no color halo appears, add 5 mL of methylene blue solution, stir for one minute, then drop the sample on the test paper 8, and observe whether there is a color halo through the camera. If not, repeat the above operation until a 1 mm stable light blue color halo appears around the precipitate. In some embodiments of the present application, the step of detecting the test paper 8, recording the mass of the added sample, the volume of the distilled water, and the parameters of the methylene blue solution, further comprises: Detecting whether a color halo appears on the test paper 8; If it has occurred, sampling and contamination are performed once at a preset interval, and the test paper 8 is tested; If color halos appear multiple times in succession, record the amount of methylene blue solution added; If the color halo appears and then disappears, the methylene blue solution is repeatedly added and stirred, and a sample is taken and stained with the test paper 8 until the color halo appears on the test paper 8 for multiple times without disappearing.

[0084] Specifically, continue stirring, conduct a staining experiment every 1 minute, and use a camera to observe the change of color halo. If the color halo appears for 5 consecutive times, record the total amount of methylene blue solution added for subsequent calculations; if the color halo disappears within 5 times, continue to add 5mL of methylene blue solution and repeat the staining experiment for 5 times until the color halo does not disappear for 5 consecutive times; In some embodiments of the present application, the detection method further comprises: The stirring device 4 stops stirring and is lifted, and the drain valve of the experimental container 1 is opened to discharge the waste liquid; Distilled water is added to the experimental container 1, the stirring device 4 is lowered and stirred, and the robot 5 puts the dipping stick 7 into the experimental container 1 for cleaning; Open the drain valve again to drain the cleaning fluid; The test strip 8 is discarded.

[0085] Specifically, the stirrer stops stirring, is lifted above the container, the bottom of the container is opened, the drain valve is opened, and the waste liquid is discharged into the waste container 10, and the valve is closed after the waste liquid is completely discharged; Add 500 mL of distilled water, lower the stirrer to start stirring, robot 5 picks up the glass rod and puts it into the container for cleaning, puts it back on the rack to dry after completion, opens the valve to control the container to discharge the cleaning liquid, and closes the valve after cleaning is completed; The robot 5 uses a suction cup to suck up the discarded test paper 8 and puts it into the waste paper container 11.

[0086] The detection system can automatically add 200g of material, add 500mL of water, stir, and quantitatively add methylene blue solution; automatically move and discard the test paper 8; automatically complete the contamination experiment; identify the color halo on the test paper 8 and determine whether the color halo appears; and automatically discharge waste liquid and clean.

[0087] Compared with the prior art, the technical solution provided by this application has the following beneficial technical effects: The present application drives the feeding device 2 and the stirring device 4 by the control device to reduce external interference. In the traditional method, the dropping and stirring process of the methylene blue solution are susceptible to human operation and the influence of the external environment, resulting in deviations in the test results. The automation scheme reduces the errors caused by improper human operation by optimizing the equipment design and operation process, and improves the accuracy of the test results. By controlling the device to drive the robot 5 and the visual inspection device 9, the steps of sampling, adding methylene blue solution, stirring, and visual inspection can be automatically completed without manual intervention, thereby improving the convenience of operation. The detection scheme realizes the rapid detection of methylene blue values ​​by optimizing the detection process and equipment performance, thereby improving the detection efficiency.
