For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

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

[0044] The test waste liquid filter box 3 includes an image sensor 2 for collecting a waste liquid image of the test waste liquid to be processed and a filter component for filtering the test waste liquid to be processed to form a filtered test waste liquid;

[0045] The test waste liquid treatment box 6 includes a plurality of pH sensors 8 for real-time monitoring of the filtered test waste liquid to obtain a real-time pH value, a switch controller for real-time opening and closing control of the acid reagent storage box 5 or the alkaline reagent storage box 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 respectively connected to the image sensor 2, the filter component, the pH sensors 8, the switch controller and the stirring component, and is used to receive and analyze the waste liquid images collected by the image sensor 2, send a filter adjustment instruction according to the analysis result, and adjust the filter component according to the filter adjustment instruction; receive and analyze the real-time pH values ​​collected by the pH sensors 8, send an opening and closing instruction and a stirring adjustment instruction according to the analysis result, adjust the switch controller according to the opening and closing instruction, and adjust the number of stirring rods 7 according to the stirring adjustment instruction.

[0047] Specifically, the test waste liquid filter box 3 described in the embodiment of the present invention is divided into a static chamber and a filter chamber by opening and closing the baffle 20, wherein the static chamber is located above the baffle 20, and the filter chamber is located below the baffle 20. When there is the test waste liquid to be treated, it enters the static chamber through the liquid inlet 1 and is left to stand for a preset time. The surface image of the test waste liquid to be treated is collected by the image sensor 2 at a preset time interval within a preset time to obtain a plurality of images, and then the particle size of impurities in the waste liquid is determined by image analysis. According to the analysis results, the central controller sends a filter adjustment instruction to the filter component to adjust the pore size of the filter, so as to more effectively remove suspended matter in the waste liquid. and impurities. In the filter chamber, after the waste liquid to be tested is filtered through the filter, filtered test waste liquid is formed and flows into the test waste liquid treatment box 6 through the first pipe. A valve 4 is arranged on the first pipe. In the treatment box, a number of pH sensors 8 monitor the pH value of the filtered test waste liquid in real time. The central controller sends an opening and closing instruction to the switch controller according to the monitoring result of the pH sensor 8 to control the opening and closing of the acid reagent storage box 5 or the alkaline reagent storage box 17, so as to add an appropriate amount of acidic or alkaline reagent to the waste liquid for neutralization. During the neutralization process, the stirring component adjusts the number of stirring rods 7 according to the stirring adjustment instruction 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 understandable that the static filtration time during the treatment of medical test waste liquid is usually 4 hours. The preset time in the embodiment of the present invention is 4 hours, and the preset time interval is 1 hour.

[0049] The present invention uses an image sensor to collect images of the inspection waste liquid to be processed in real time. The central controller can quickly analyze the impurity particle size in the waste liquid, thereby accurately adjusting the filter parameters of the filter component to ensure the optimization of the filtering effect and improve the initial efficiency of the waste liquid treatment. Through real-time pH value monitoring and intelligent control of the acid-base neutralization process, the pH adjustment of the waste liquid is more accurate, reducing the need for manual intervention, while improving the treatment efficiency and accuracy.

[0050] Continue reading Figure 1 As shown, the interior of 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 still chamber and a filter chamber, wherein the still chamber is located above the baffle and is used to allow the waste liquid to be treated to stand for a preset time, and the filter chamber is located below the baffle and is used to filter a number of impurities in the waste liquid to be treated.

[0051] It can be understood that the opening and closing of the opening and closing baffle can be completed by translation and extension, or by separating from the middle and rotating the baffles on both sides downward by a certain angle. The rotation angle can be determined according to the parameters and shape of the specific filter chamber setting. All of the above-mentioned opening and closing methods fall within the protection scope of the present invention and will not be repeated here.

[0052] Continue reading Figure 1 As shown, the filter assembly includes a fixed filter 13, a movable filter 14, a first motor 16 and a telescopic rod 15, wherein the two ends of the fixed filter 13 are fixedly connected to the inner walls on both sides of the filter chamber respectively, the movable filter 14 is arranged below the fixed filter 13, and it is in contact with the fixed filter 13, the first motor 16 is fixedly arranged on the outer wall of the inspection waste liquid filter 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 14, so as to drive the telescopic rod 15 to reciprocate through the first motor 16 to move the movable filter 14.

[0053] In one feasible manner, the output shaft of the first motor 16 is tightly and fixedly connected to one end of the telescopic rod 15 through a through hole provided on the side wall of the inspection 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 mobile filter 14 will also reciprocate accordingly, thereby adjusting the overlapping area between the fixed filter 13 and the mobile filter 14 to effectively filter impurities.

[0054] In a feasible manner, the first motor 16 can be fixed to the outer wall of the inspection waste liquid filter box by welding.

[0055] Continue to see Figure 1 As shown, the stirring assembly includes a second motor 18, a stirring main rod 9, a plurality of telescopic pillars 10 and a plurality of stirring support rods 7, wherein the second motor 18 is fixed to one side of the inspection waste liquid treatment box 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 inspection waste liquid treatment box 6, one end of the plurality of stirring support rods 7 is fixedly connected to the stirring main rod 9, one end of the plurality of telescopic pillars 10 is slidably connected to the stirring main rod 9, and the other end of the plurality of telescopic pillars 10 is fixedly connected to the plurality of stirring main rods 9, so as to respectively support the corresponding stirring main rods 9.

[0056] In one practicable manner, the other end of the stirring main rod 9 is fixedly connected to the other side of the test waste liquid treatment box 6 through a fixing device such as a bearing seat or a bracket;

[0057] In one feasible manner, 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 starts to rotate and drives 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 improving the quality of the treatment results.

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

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

[0060] A first instruction generating unit 200, connected to the image processing unit 100, for generating a filter adjustment instruction based on the target screening particle size;

[0061] The filter adjustment unit 300 is connected to the first instruction generating unit 200, and is used to receive the filter adjustment instruction, and adjust the first motor 16 according to the filter adjustment instruction, so that it drives the telescopic rod 15 to move the mobile filter 14 to achieve adjustment of the filter assembly.

[0062] Specifically, the embodiment of the present invention sets an image processing unit to accurately identify the edge contour in the waste liquid image through an edge detection algorithm, providing a basis for identifying the impurity particle size, and uses a measuring tool to identify the maximum diameter of the edge contour as the impurity particle size, so as to accurately determine the actual size of the impurity, and count the proportion of several impurity particle sizes in any waste liquid image, so as to provide data support for selecting the initial screening particle size, ensure the representativeness and accuracy of the target screening particle size, and improve the efficiency and accuracy of waste liquid treatment. By setting a first instruction generation unit to quickly generate a filter adjustment instruction based on the target screening particle size provided by the image processing unit, the accuracy of the filter adjustment is ensured, thereby ensuring the filtering effect. By setting a filter adjustment unit to drive the telescopic rod by adjusting the first motor, so as to move the mobile filter, dynamic adjustment of the filter assembly is realized, and flexible adjustment is performed according to different waste liquid characteristics, ensuring the adaptability and flexibility of the treatment system, and accurate filter adjustment enables the filter assembly to more effectively remove impurities in the waste liquid, improves the treatment effect, and ensures the quality of the treated waste liquid.

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

[0064] A calculation subunit, for calculating the offset distance of the mobile filter 14 based on the target screening particle size, the diameter of the fixed filter 13 and the diameter of the mobile filter 14;

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

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

[0067] It is understandable that the maximum spacing of the overlapping areas should be smaller than the target screening particle size to achieve the purpose of filtering impurities.

[0068] See also Figure 3 The figure shows a possible example of a top view of the fixed filter screen and the movable filter screen after adjustment in the embodiment of the present invention.

[0069] Continue to see Figure 2 As shown, the central controller also includes:

[0070] An opening instruction generating unit 400 is used to identify an initial pH value based on a plurality of said real-time pH values ​​corresponding to any pH sensor 8, calculate an average of the plurality of initial pH values ​​as a pH value of the filtration test waste liquid, and generate an opening instruction based on the pH value of the filtration test waste liquid;

[0071] A curve drawing unit 500 is used to draw a pH value change curve based on the several real-time pH values ​​corresponding to any pH sensor 8 to obtain several pH value change curves;

[0072] A curve analysis unit 600, connected to the curve drawing unit 500, is used to analyze a plurality of pH value change curves, and determine the pH value change trend and the real-time distribution uniformity of the pH value based on the analysis results;

[0073] A closing instruction generating unit 700, connected to the curve analyzing unit 600, for generating a closing instruction based on the pH value variation trend;

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

[0075] In implementation, the opening instruction generating unit is used to generate an alkaline opening instruction to open the alkaline reagent storage box 17 when it is determined that the initial pH value is acidic, and to generate an acidic opening instruction to open the acidic reagent storage box 5 when it is determined that the initial pH value is alkaline.

[0076] It can be understood that 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, wherein the preset pH value is 7.

[0077] The present invention rapidly calculates the average pH value of the filtration test waste liquid based on the real-time pH value by setting an opening instruction generation unit, generates an opening instruction accordingly, starts the subsequent acid-base neutralization treatment process, improves the treatment efficiency, realizes intelligent decision-making by calculating the average pH value as a trigger condition, improves the accuracy and reliability of the treatment, draws a pH value change curve by setting a curve drawing unit, intuitively displays the pH change of the waste liquid during the treatment process, makes the data in the treatment process more intuitive and easy to understand, determines the pH change trend by setting a curve analysis unit, provides a basis for the subsequent initiation of a closing instruction, evaluates the pH distribution of the waste liquid during the treatment process by analyzing the real-time distribution uniformity of the pH value, ensures the consistency and stability of the treatment effect, generates a closing instruction according to the pH value change trend by setting a closing instruction generation unit, accurately controls the end point of the acid-base neutralization treatment, avoids the situation of over-treatment or under-treatment, improves the treatment efficiency and resource utilization, generates a stirring adjustment instruction according to the real-time distribution uniformity of the pH value by setting a stirring instruction generation unit, adjusts the number of stirring rods, ensures the full progress of the acid-base neutralization reaction and the uniform treatment of the waste liquid, and improves the quality of the treated waste liquid.

[0078] See also Figure 4 As shown, the closing instruction generating unit 700 includes:

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

[0080] The closing instruction generating subunit 720 is connected to the trend identifying subunit 71 and is used to generate the closing instruction based on the target time.

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

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

[0083] It can be understood that, in the embodiment of the present 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] The present invention realizes automation and intelligence of the waste liquid treatment process through precise pH value monitoring and intelligent analysis, which not only improves the treatment efficiency and resource utilization, but also ensures the safety of the treatment process and the stability of the final waste liquid quality.

[0085] Specifically, the stirring instruction generating unit includes:

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

[0087] The stirring instruction generating subunit is connected to the uniformity judging subunit, and is used to judge the number of the stirring support 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 instruction based on the number judgment result.

[0088] It can be understood that the uniformity judgment subunit can judge the real-time distribution uniformity of the pH value through the comparison results of several real-time pH values ​​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] It is understandable that one possible example of the stirring instruction generation subunit of the present invention is that when it is detected that the pH value distribution uniformity is lower than a preset threshold, the stirring instruction generation unit will issue an instruction to increase the number of stirring rods to enhance the stirring effect and ensure uniform treatment of the waste liquid. On the contrary, if the pH value distribution uniformity is greater than or equal to the preset threshold, the number of stirring rods is not adjusted.

[0090] It is understandable that the initial number of stirring support rods in the embodiment of the present invention can be determined according to the number of stirring support rods set in the historical processing process.

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

[0092] Specifically, it also includes a test waste liquid recovery box, which is connected to the test waste liquid treatment box 6 through a second pipeline to recover the test waste liquid after neutralization and treatment in the test waste liquid treatment box 6 to obtain the target test waste liquid.

[0093] It can be understood that after the treated waste test liquid in the waste test liquid treatment box 6 reaches the neutralization standard, the second pipeline valve is opened and flows into 12 through the second pipeline 11 to recycle the medical test waste liquid.
