[0014] The first instruction generation unit is connected to the image processing unit and is used to generate filter adjustment instructions based on the target screening particle size.

[0015] A filter adjustment unit, connected to the first instruction generation unit, is used to receive the filter adjustment instruction and adjust the first motor according to the filter adjustment instruction, so that it drives the telescopic rod to move the movable filter, thereby realizing the adjustment of the filter assembly.

[0016] Further, the first instruction generation unit includes:

[0017] The calculation subunit is used to calculate the offset distance of the moving filter based on the target screening particle size, the fixed filter diameter, and the moving filter diameter;

[0018] An instruction generation subunit, connected to the calculation subunit, is used to generate the filter adjustment instruction based on the offset distance.

[0019] Furthermore, the central controller also includes:

[0020] The start command generation unit is used to identify an initial pH value based on several real-time pH values ​​corresponding to any pH sensor, calculate the average of several initial pH values ​​as the pH value of the filter test waste liquid, and generate an start command based on the pH value of the filter test waste liquid.

[0021] The curve plotting unit is used to plot pH change curves based on the real-time pH values ​​corresponding to any pH sensor, thereby obtaining several pH change curves.

[0022] A curve analysis unit, connected to the curve plotting unit, is used to analyze several pH value change curves and determine the pH value change trend and the real-time pH value distribution uniformity based on the analysis results.

[0023] A closure instruction generation unit is connected to the curve analysis unit to generate a closure instruction based on the pH value change trend;

[0024] A stirring command generation unit is connected to the curve analysis unit to generate the stirring adjustment command based on the real-time distribution uniformity of the pH value.

[0025] Furthermore, the closure instruction generation unit includes:

[0026] The trend recognition subunit is used to identify the trend of any pH value change curve, calculate the predicted time for the real-time pH value to reach the target pH value based on the trend, and calculate the average of several predicted times as the target time.

[0027] A closure instruction generation subunit is connected to the trend recognition subunit to generate the closure instruction based on the target time.

[0028] Furthermore, the stirring instruction generation unit includes:

[0029] The uniformity judgment subunit is used to identify the real-time pH value corresponding to the same moment based on several real-time pH value change curves, and to judge the real-time distribution uniformity of the pH value based on the comparison results of several real-time pH values.

[0030] A stirring command generation subunit is connected to the uniformity judgment subunit to determine the number of stirring rods corresponding to the pH sensor monitoring area based on the real-time pH value distribution uniformity, and to generate the stirring adjustment command based on the number judgment result.

[0031] Furthermore, it also includes a test waste liquid recovery tank, which is connected to the test waste liquid treatment tank via a second pipe, for recovering the test waste liquid in the test waste liquid treatment tank and after treatment, so as to obtain the target test waste liquid.

[0032] Compared with the prior art, the beneficial effects of the present invention are that by acquiring images of the test waste liquid to be treated in real time through an image sensor, the central controller can quickly analyze the particle size of impurities in the waste liquid, thereby accurately adjusting the filter parameters of the filter components to ensure optimal filtration effect and improve the initial efficiency of waste liquid treatment. Through real-time pH monitoring and intelligent control of the acid-base neutralization process, the acidity and alkalinity adjustment of the waste liquid is more precise, reducing the need for manual intervention and improving treatment efficiency and accuracy.

[0033] In particular, by setting the image processing unit to accurately identify the edge contours in the waste liquid image through an edge detection algorithm, a basis is provided for identifying the impurity particle size. The maximum diameter of the edge contour is identified by a measurement tool as the impurity particle size, which accurately determines the actual size of the impurities. The proportion of several impurity particle sizes in any waste liquid image is statistically analyzed, providing data support for selecting the initial screening particle size, ensuring the representativeness and accuracy of the target screening particle size, and improving the efficiency and precision of waste liquid treatment. By setting the first instruction generation unit to quickly generate filter adjustment instructions based on the target screening particle size provided by the image processing unit, the accuracy of filter adjustment is ensured, thereby guaranteeing the filtration effect. By setting the filter adjustment unit to adjust the first motor to drive the telescopic rod, the moving filter is moved, realizing the dynamic adjustment of the filter component. Flexible adjustments are made according to different waste liquid characteristics, ensuring the adaptability and flexibility of the treatment system. Precise filter adjustment enables the filter component to remove impurities in the waste liquid more effectively, improving the treatment effect and ensuring the quality of the treated waste liquid.

[0034] In particular, by setting up an activation command generation unit to quickly calculate the average pH value of the filtered test waste liquid based on real-time pH value, and generating an activation command accordingly to initiate the subsequent acid-base neutralization process, the processing efficiency is improved. By using the calculated average pH value as a trigger condition, intelligent decision-making is achieved, improving the accuracy and reliability of the processing. By setting up a curve plotting unit to draw a pH value change curve, the acidity and alkalinity changes of the waste liquid during the treatment process are intuitively displayed, making the data in the processing process more intuitive and easy to understand. By setting up a curve analysis unit to determine the pH value change trend, a basis is provided for the subsequent activation of the closure command. By analyzing the real-time distribution uniformity of pH value, the acidity and alkalinity distribution of the waste liquid during the treatment process is assessed, ensuring the consistency and stability of the treatment effect. By setting up a closure command generation unit to generate a closure command based on the pH value change trend, the endpoint of the acid-base neutralization process is precisely controlled, avoiding over-treatment or under-treatment, thus improving the processing efficiency and resource utilization. By setting up a stirring command generation unit to generate a stirring adjustment command based on the real-time distribution uniformity of pH value, the number of stirring rods is adjusted to ensure the full progress of the acid-base neutralization reaction and the uniform treatment of the waste liquid, thereby improving the quality of the treated waste liquid.

This is merely for the convenience of description and does not indicate or imply that the module or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0042] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] See Figure 1 As shown, an embodiment of the present invention provides a medical laboratory waste liquid treatment system, the system comprising:

[0044] The test waste liquid filter box 3 includes an image sensor 2 that acquires images of the test waste liquid to be processed and a filter assembly that filters the test waste liquid to be processed to form a filtered test waste liquid.

[0045] The test waste liquid treatment tank 6 includes several pH sensors 8 for real-time monitoring of the filtered test waste liquid to obtain real-time pH values, a switch controller for real-time opening and closing of the acid reagent storage tank 5 or the alkaline reagent storage tank 17, and a stirring assembly for adjusting the number of stirring rods 7 during the acid-base neutralization process of the filtered test waste liquid.

[0046] The central controller is connected to the image sensor 2, the filter assembly, several pH sensors 8, the switch controller, and the stirring assembly, respectively. It is used to receive and analyze several waste liquid images collected by the image sensor 2, send filter adjustment commands based on the analysis results, and adjust the filter assembly according to the filter adjustment commands. It is also used to receive and analyze several real-time pH values ​​collected by several pH sensors 8, send opening and closing commands and stirring adjustment commands based on the analysis results, adjust the switch controller according to the opening and closing commands, and adjust the number of stirring rods 7 according to the stirring adjustment commands.

[0047] Specifically, in this embodiment of the invention, the test waste liquid filter box 3 is divided into a settling chamber and a filtration chamber by an opening and closing baffle 20. The settling chamber is located above the baffle 20, and the filtration chamber is located below the baffle 20. When there is test waste liquid to be treated, it is introduced into the settling chamber through the inlet 1 and left to stand for a preset time. At preset time intervals, the surface images of the test waste liquid to be treated are acquired by the image sensor 2, obtaining several images. Then, the particle size of impurities in the waste liquid is determined by image analysis. Based on the analysis results, the central controller sends a filter adjustment command to the filter assembly to adjust the pore size of the filter screen, thereby more effectively removing suspended solids from the waste liquid. In the filtration chamber, the waste liquid to be tested is filtered through a filter screen to form filtered test waste liquid, which flows into the test waste liquid treatment tank 6 through the first pipe. A valve 4 is installed on the first pipe. In the treatment tank, several pH sensors 8 monitor the pH value of the filtered test waste liquid in real time. According to the monitoring results of the pH sensors 8, the central controller sends an opening and closing command to the switch controller to control the opening and closing of the acid reagent storage tank 5 or the alkaline reagent storage tank 17, thereby adding an appropriate amount of acid or alkaline reagent to the waste liquid for neutralization. During the neutralization process, the stirring assembly adjusts the number of stirring rods 7 according to the stirring adjustment command of the central controller to ensure that the reagent and the waste liquid are fully mixed to achieve a uniform pH value.

[0048] It is understood that the settling and filtration time during the treatment of medical testing waste liquid is usually 4 hours. The preset time in this embodiment of the invention is 4 hours and the preset time interval is 1 hour.

[0049] This invention uses an image sensor to acquire images of the waste liquid to be processed in real time. The central controller can quickly analyze the particle size of impurities in the waste liquid, thereby accurately adjusting the filter parameters of the filtration components to ensure optimal filtration effect and improve the initial efficiency of waste liquid treatment. Through real-time pH monitoring and intelligent control of the acid-base neutralization process, the acidity and alkalinity adjustment of the waste liquid is more precise, reducing the need for manual intervention and improving processing efficiency and accuracy.

[0050] Continue reading Figure 1 As shown, the test waste liquid filter box also includes an opening and closing baffle 19, which is used to divide the test waste liquid filter box into a settling chamber and a filtration chamber. The settling chamber is located above the baffle and is used to settling the waste liquid to be treated for a preset time. The filtration chamber is located below the baffle and is used to filter out several impurities in the waste liquid to be treated.

[0051] It is understood that the opening and closing of the baffle can be accomplished by translation and extension, or by separating in the middle and rotating the two baffles downwards at a certain angle. The angle of rotation can be determined according to the parameters and shape of the specific filter chamber. All of the above opening and closing methods fall within the protection scope of this invention, and will not be elaborated here.

[0052] Continue reading Figure 1 As shown, the filtration assembly includes a fixed filter screen 13, a movable filter screen 14, a first motor 16, and a telescopic rod 15. The two ends of the fixed filter screen 13 are fixedly connected to the inner walls of both sides of the filtration chamber. The movable filter screen 14 is disposed below the fixed filter screen 13 and fits against it. The first motor 16 is fixedly disposed on the outer wall of the test waste liquid filtration box. One end of the telescopic rod 15 is fixedly connected to the first motor 16, and the other end is fixedly connected to one end of the movable filter screen 14, so that the first motor 16 drives the telescopic rod 15 to reciprocate, thereby moving the movable filter screen 14.

[0053] In one possible implementation, the output shaft of the first motor 16 is tightly fixedly connected to one end of the telescopic rod 15 through a through hole provided on the side wall of the waste liquid filter box. When the first motor 16 receives a start signal, it starts to rotate and drives the telescopic rod 15 to reciprocate through the output shaft. As the telescopic rod 15 reciprocates, the moving filter screen 14 will also reciprocate accordingly, thereby adjusting the overlapping area between the fixed filter screen 13 and the moving filter screen 14 to effectively filter impurities.

[0054] In one possible implementation, the first motor 16 can be fixed to the outer wall of the test waste liquid filter box by welding.

[0055] See also Figure 1 As shown, the stirring assembly includes a second motor 18, a stirring main rod 9, several telescopic support columns 10, and several stirring support rods 7. The second motor 18 is fixed to one side of the test waste liquid treatment tank 6. One end of the stirring main rod 9 is fixedly connected to the second motor 18, and the other end is fixedly connected to the other side of the test waste liquid treatment tank 6. One end of each of the stirring support rods 7 is fixedly connected to the stirring main rod 9. One end of each of the telescopic support columns 10 is slidably connected to the stirring main rod 9, and the other end of each of the telescopic support columns 10 is fixedly connected to the stirring main rod 9 to support the corresponding stirring main rod 9.

[0056] In one possible implementation, the other end of the stirring rod 9 is fixedly connected to the other side of the test waste liquid treatment tank 6 by some kind of fixing device such as a bearing seat or bracket;

[0057] In one possible implementation, the output shaft of the second motor 18 is fixedly connected to one end of the stirring main rod 9. When the second motor 18 receives a start signal, it will start to rotate and drive the stirring main rod 9 and the stirring support rod 7 to rotate, which helps the chemical substances in the waste liquid to mix and react more fully, thereby improving the uniformity of the treatment process and the quality of the treatment results.

[0058] See Figure 2 As shown, the central controller includes:

[0059] The image processing unit 100 is used to identify several edge contours in any waste liquid image based on an edge detection algorithm, identify the maximum diameter of any edge contour as the impurity particle size based on a measurement tool, count the proportion of several impurity particle sizes in any waste liquid image, select the impurity particle size corresponding to the largest proportion as the initial screening particle size, and calculate the average of several initial screening particle sizes corresponding to several waste liquid images as the target screening particle size.

[0060] The first instruction generation unit 200 is connected to the image processing unit 100 and is used to generate filter adjustment instructions based on the target screening particle size.

[0061] The filter adjustment unit 300 is connected to the first instruction generation unit 200 and is used to receive the filter adjustment instruction. According to the filter adjustment instruction, the first motor 16 is adjusted so that it drives the telescopic rod 15 to move the movable filter 14, so as to realize the adjustment of the filter assembly.

[0062] Specifically, this embodiment of the invention sets up an image processing unit to accurately identify the edge contours in waste liquid images using an edge detection algorithm, providing a basis for identifying impurity particle sizes. The maximum diameter of the edge contour is identified using a measuring tool as the impurity particle size, ensuring accurate determination of the actual size of the impurities. The proportion of several impurity particle sizes in any waste liquid image is statistically analyzed, providing data support for selecting the initial screening particle size, ensuring the representativeness and accuracy of the target screening particle size, and improving the efficiency and precision of waste liquid treatment. A first instruction generation unit quickly generates filter adjustment instructions based on the target screening particle size provided by the image processing unit, ensuring the precision of filter adjustment and thus guaranteeing the filtration effect. The filter adjustment unit adjusts the first motor to drive the telescopic rod, thereby moving the filter and achieving dynamic adjustment of the filtration component. Flexible adjustments are made according to different waste liquid characteristics, ensuring the adaptability and flexibility of the treatment system. Precise filter adjustment enables the filtration component to more effectively remove impurities from the waste liquid, improving the treatment effect and ensuring the quality of the treated waste liquid.

[0063] Specifically, the first instruction generation unit includes:

[0064] The calculation subunit is used to calculate the offset distance of the moving filter 14 based on the target screening particle size, the diameter of the fixed filter 13, and the diameter of the moving filter 14;

[0065] An instruction generation subunit, connected to the calculation subunit, is used to generate the filter adjustment instruction based on the offset distance.

[0066] It is understood that the present invention can determine the maximum spacing of the overlapping areas of the fixed filter and the moving filter by determining the target screening particle size, and calculate the offset distance based on the maximum spacing of the overlapping areas and the initial overlapping spacing between the initial fixed filter and the moving filter.

[0067] Understandably, the maximum spacing between overlapping regions should be smaller than the target particle size in order to achieve the purpose of filtering impurities.

[0068] See Figure 3 The image shown is a possible example of a top view of the adjusted fixed filter and the movable filter in an embodiment of the present invention.

[0069] See also Figure 2 As shown, the central controller also includes:

[0070] The start command generation unit 400 is used to identify an initial pH value based on several real-time pH values ​​corresponding to any pH sensor 8, calculate the average of several initial pH values ​​as the pH value of the filter test waste liquid, and generate an start command based on the pH value of the filter test waste liquid.

[0071] The curve plotting unit 500 is used to plot pH change curves based on the several real-time pH values ​​corresponding to any pH sensor 8, thereby obtaining several pH change curves.

[0072] The curve analysis unit 600 is connected to the curve plotting unit 500 and is used to analyze several pH value change curves, and determine the pH value change trend and the real-time pH value distribution uniformity based on the analysis results.

[0073] A closure instruction generation unit 700 is connected to the curve analysis unit 600 and is used to generate a closure instruction based on the pH value change trend.

[0074] The stirring command generation unit 800 is connected to the curve analysis unit 600 and is used to generate the stirring adjustment command based on the real-time distribution uniformity of the pH value.

[0075] In practice, the opening command generation unit is used to generate an alkaline opening command when the initial pH value is determined to be acidic, thereby opening the alkaline reagent storage box 17, and to generate an acidic opening command when the initial pH value is determined to be alkaline, thereby opening the acidic reagent storage box 5.

[0076] Understandably, when the initial pH value is less than the preset pH value, the filtered test waste liquid is acidic, and when the initial pH value is greater than the preset pH value, the filtered test waste liquid is alkaline. The preset pH value is 7.

[0077] This invention improves processing efficiency by using an activation command generation unit to rapidly calculate the average pH value of the filtered test waste liquid based on real-time pH values ​​and generate an activation command accordingly to initiate the subsequent acid-base neutralization process. By using the calculated average pH value as a trigger condition, intelligent decision-making is achieved, improving the accuracy and reliability of the treatment. A curve plotting unit generates a pH value change curve, visually displaying the acidity and alkalinity changes of the waste liquid during treatment, making the data more intuitive and understandable. A curve analysis unit determines the pH value change trend, providing a basis for initiating a subsequent closure command. Analyzing the real-time pH value distribution uniformity assesses the acidity and alkalinity distribution of the waste liquid during treatment, ensuring the consistency and stability of the treatment effect. A closure command generation unit generates a closure command based on the pH value change trend, precisely controlling the endpoint of the acid-base neutralization process and avoiding over- or under-treatment, thus improving processing efficiency and resource utilization. A stirring command generation unit generates stirring adjustment commands based on the real-time pH value distribution uniformity, adjusting the number of stirring rods to ensure the full progress of the acid-base neutralization reaction and uniform treatment of the waste liquid, improving the quality of the treated waste liquid.

[0078] See Figure 4 As shown, the closure instruction generation unit 700 includes:

[0079] Trend recognition subunit 710 is used to identify the trend of any pH value change curve, calculate the predicted time for the real-time pH value to reach the target pH value based on the trend, and calculate the average of several predicted times as the target time.

[0080] A closure instruction generation subunit 720 is connected to the trend recognition subunit 71 to generate the closure instruction based on the target time.

[0081] Specifically, the target pH value described in this embodiment of the invention is 7.

[0082] It is understood that in the embodiments of the present invention, the trend of change can be identified by identifying the slope of any pH value change curve. The slope is used to determine the speed of pH value change. The larger the slope, the faster the pH value changes, and vice versa.

[0083] It is understood that, in this embodiment of the invention, the predicted time can be calculated by the slope of the curve and the difference between the current pH value and the target pH value.

[0084] This invention automates and intelligently analyzes the wastewater treatment process through precise pH monitoring, which not only improves treatment efficiency and resource utilization but also ensures the safety of the treatment process and the stability of the final wastewater quality.

[0085] Specifically, the stirring command generation unit includes:

[0086] The uniformity judgment subunit is used to identify the real-time pH value corresponding to the same moment based on several real-time pH value change curves, and to judge the real-time distribution uniformity of the pH value based on the comparison results of several real-time pH values.

[0087] A stirring command generation subunit is connected to the uniformity judgment subunit to determine the number of stirring rods 7 corresponding to the monitoring area of ​​the pH sensor 8 based on the real-time distribution uniformity of the pH value, and to generate the stirring adjustment command based on the number judgment result.

[0088] It is understandable that the uniformity judgment subunit can determine the real-time distribution uniformity of pH values ​​by comparing the results of several real-time pH values. This can be achieved by calculating the standard deviation of several real-time pH values. The smaller the standard deviation, the more uniform the pH value distribution, and vice versa.

[0089] Understandably, one possible instance of the stirring command generation subunit of this invention is that when the pH value distribution uniformity is detected to be lower than a preset threshold, the stirring command generation unit will issue a command to increase the number of stirring rods to enhance the stirring effect and ensure uniform treatment of the waste liquid. Conversely, if the pH value distribution uniformity is greater than or equal to the preset threshold, the number of stirring rods will not be adjusted.

[0090] It is understood that the initial number of stirring support rods in the embodiments of the present invention can be determined based on the number set in the historical processing.

[0091] It is understood that the adjustment of the stirring rod 7 can be achieved by mechanically changing its position in the treatment tank, or by increasing or decreasing the number of stirring rods. In this application, the adjustment is made by increasing or decreasing the number of stirring rods to ensure that the reagent and waste liquid are fully mixed and a uniform pH value is achieved.

[0092] Specifically, it also includes a test waste liquid recovery tank, which is connected to the test waste liquid treatment tank 6 via a second pipe, for recovering the test waste liquid after neutralization and treatment in the test waste liquid treatment tank 6, so as to obtain the target test waste liquid.

[0093] Understandably, after the treated waste liquid in the waste liquid treatment tank 6 reaches the neutralization standard, the valve of the second pipeline is opened, and the waste liquid flows into the tank 12 through the second pipeline 11 to recycle the medical waste liquid.

[0094] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.

[0095] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
