Description

Technical Field

[0001] The present invention relates to the field of dissolution analysis and detection, and in particular to a method and system for detecting the dissolution adequacy of dry powder A. Background Art

[0002] In the online liquid preparation process of the dialysis equipment, the solubility sufficiency of dry powder A plays a vital role. In order to accurately detect the dissolution of dry powder A and obtain a solution that meets the liquid preparation requirements, it is necessary to accurately evaluate the solubility sufficiency of dry powder A.

[0003] At present, the existing technology mainly uses optical detection for the detection of powder dissolution sufficiency. The initial light intensity without powder is compared with the light intensity after the powder begins to dissolve, and the dissolution sufficiency detection result is obtained by calculating the light shielding rate. However, the existing powder dissolution sufficiency detection method that only relies on optical principles is prone to insufficient detection and cannot ensure whether the powder has been fully dissolved, resulting in poor accuracy of the powder dissolution sufficiency detection result. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a method and system for detecting the sufficiency of dissolution of dry powder A, which combines optical detection means with conductivity detection means to ensure that dry powder A is fully dissolved and improve the accuracy of the detection result of the sufficiency of dissolution of dry powder A.

[0005] To achieve the above-mentioned purpose, an embodiment of the present invention provides a method for detecting the adequacy of dissolution of dry powder A, which is applied to the cyclic dissolution process of dry powder A, including: executing the cyclic dissolution adequacy detection process of dry powder A: in the cyclic dissolution process of dry powder A, obtaining the light intensity change value of the dry powder A solution at the current moment; if the light intensity change value at the current moment is equal to 0, obtaining the conductivity change value of the solution at the current moment; if the conductivity change value of the solution at the current moment is equal to 0, outputting the A dry powder dissolution adequacy detection result, and ending the A dry powder dissolution adequacy detection process.

[0006] The embodiment of the present invention proposes a method for detecting the adequacy of dissolution of dry powder A. The method comprises the following steps: optically detecting the solution of dry powder A, obtaining the light intensity change value at the current moment, judging whether the light intensity change value at the current moment meets the requirements, and if the light intensity change value at the current moment meets the detection requirements, it indicates that the particle content in the corresponding solution at this moment meets the requirements, and then detecting and analyzing the conductivity of the solution at this moment, obtaining the conductivity change value of the solution at the current moment, and if the conductivity change value of the solution at the current moment meets the detection requirements, it indicates that the solution has been fully dissolved. Through the above scheme, the light intensity change value of the solution at the current moment is obtained, providing a real-time and reliable detectable data basis, without the need to detect the light intensity in a powder-free state, and further analyzing whether the solution is fully dissolved in combination with the conductivity detection, thereby better ensuring that the dry powder A is fully dissolved, avoiding the problem of inaccurate analysis results of the adequacy of dissolution of dry powder A caused by only detecting the solution through optical principles, and improving the accuracy of the detection results of the adequacy of dissolution of dry powder A.

[0007] Furthermore, in the process of cyclic dissolution of dry powder A, obtaining the light intensity change value of the dry powder solution A at the current moment also includes: obtaining the light intensity change value of the dry powder solution A at the previous moment; comparing the light intensity change value at the current moment with the light intensity change value at the previous moment once; in the first comparison, if the light intensity change value at the current moment is not less than the light intensity change value at the previous moment, then comparing the light intensity change value at the current moment with the light intensity change value at the previous moment for a second time; in the second comparison, if the light intensity change value at the current moment is equal to the light intensity change value at the previous moment, then judging whether the light intensity change value at the current moment is equal to 0; if the light intensity change value at the current moment is not equal to 0, then re-executing the A dry powder cyclic dissolution sufficiency detection process until the light intensity change value at the current moment is equal to 0. The first comparison of the light intensity change value at the current moment and the light intensity change value at the previous moment also includes: in the first comparison, if the light intensity change value at the current moment is less than the light intensity change value at the previous moment, then re-execute the A dry powder cyclic dissolution adequacy detection process until the light intensity change value at the current moment is not less than the light intensity change value at the previous moment. In the first comparison, if the light intensity change value at the current moment is not less than the light intensity change value at the previous moment, then the second comparison of the light intensity change value at the current moment and the light intensity change value at the previous moment also includes: in the second comparison, if the light intensity change value at the current moment is not equal to the light intensity change value at the previous moment, then re-execute the A dry powder cyclic dissolution adequacy detection process until the light intensity change value at the current moment is equal to the light intensity change value at the previous moment.

[0008] Through the above scheme, by obtaining the light intensity change value at the previous moment, comparing the difference of the light intensity change value at the adjacent moment, and then analyzing the light intensity change value at the adjacent moment according to the pre-set detection requirements, if there is a difference in the comparison results of the light intensity change values ​​at adjacent moments, it means that there are still solid particles in the solution, the dissolution is not sufficient, and the dissolution needs to be circulated again. If the light intensity change value at the adjacent moment meets the preset requirements, it means that the particle content in the corresponding solution at this time meets the requirements, thereby realizing the detection of liquid solid particles, ensuring that the A dry powder solution is fully dissolved, and improving the accuracy of the A dry powder dissolution sufficiency detection result. In addition, at adjacent moments On the premise that there is no difference in the comparison results of the engraved light intensity change values, the light intensity change value at the current moment is analyzed again, and the analysis of the light intensity change value itself is added to determine whether the light intensity change value at the current moment meets the preset detection requirements. If the light intensity change value at the current moment does not meet the preset detection requirements, it means that the dissolution of dry powder A has not yet stabilized and the dissolution is not sufficient. If the light intensity change value at the current moment meets the preset detection requirements, it means that the optical detection result at this time is that dry powder A is fully dissolved. Therefore, when performing optical principle detection, multiple conditions are compared and analyzed to improve the accuracy of optical detection and thus improve the accuracy of the detection result of the sufficiency of dry powder A dissolution.

[0009] Furthermore, if the light intensity change value at the current moment is equal to 0, then the solution conductivity change value at the current moment is obtained, and it also includes: obtaining the solution conductivity change value at the previous moment; comparing the solution conductivity change value at the current moment with the solution conductivity change value at the previous moment once; in the first comparison, if the solution conductivity change value at the current moment is not less than the solution conductivity change value at the previous moment, then comparing the solution conductivity change value at the current moment with the solution conductivity change value at the previous moment for a second time; in the second comparison, if the solution conductivity change value at the current moment is equal to the solution conductivity change value at the previous moment, then judging whether the solution conductivity change value at the current moment is equal to 0; if the solution conductivity change value at the current moment is not equal to 0, then re-executing the A dry powder cyclic dissolution sufficiency detection process until the solution conductivity change value at the current moment is equal to 0.

[0010] In order to solve the problem of poor accuracy of detection results caused by the prior art relying solely on optical principles to detect powder dissolution, the above scheme also proposes to combine conductivity detection of the solution, and judge the conductivity change values ​​at adjacent moments. If the conductivity change values ​​at adjacent moments do not meet the corresponding detection requirements, it can be reflected that the liquid dissolution of the solution in the circulation loop is not sufficient and still needs further dissolution. If the conductivity change values ​​at adjacent moments meet the corresponding detection requirements, it means that the solution is fully dissolved in the circulation loop. By combining conductivity detection with optical detection, the solution is fully dissolved not only under the detection of optical principles, but also under conductivity detection, so as to provide more reliable detection results, thereby improving the accuracy of the detection results of the A dry powder dissolution sufficiency.

[0011] Furthermore, in the secondary comparison, if the solution conductivity change value at the current moment is equal to the solution conductivity change value at the previous moment, then it is determined whether the solution conductivity change value at the current moment is equal to 0, and it also includes: if the solution conductivity change value at the current moment is equal to 0, obtaining the dissolution time of dry powder A at the current moment; if the dissolution time of dry powder A at the current moment meets the preset dissolution time requirement, determining the solution conductivity detection value at the current moment; if the solution conductivity detection value at the current moment meets the preset qualified range requirement, then outputting the A dry powder dissolution sufficiency detection result, and ending the A dry powder cyclic dissolution sufficiency detection process.

[0012] In order to further improve the accuracy of the test results of the adequacy of dissolution of dry powder A, through the above scheme, after the optical detection and the conductivity detection are completed, the dissolution time of the solution is also analyzed to prevent randomness in the data analysis process, ensure that the dissolution time of the solution meets the requirements during the cyclic dissolution execution process, and make the data analysis process of the sufficient dissolution of the solution more reliable. In addition, in order to make up for the problem that the prior art only performs optical detection on the solution, which can only indicate the dissolution of dry powder A, and cannot analyze the composition of the solution, and there is a problem of low detection reliability, through the pre-set qualified range, by adding the analysis of the solution conductivity detection value, the composition of the solution is analyzed to ensure the correctness of the dissolved material composition, avoid unnecessary accidents, and improve the accuracy of the test results of the adequacy of dissolution of dry powder A.

[0013] Furthermore, before executing the A dry powder cyclic dissolution sufficiency detection process, it also includes: presetting a solution circulation cycle and setting the solution circulation cycle to 0; if the A dry powder dissolution time at the current moment meets the preset dissolution time requirement, judging the solution conductivity detection value at the current moment, including: if the A dry powder dissolution time at the current moment meets the preset dissolution time requirement, increasing the solution circulation cycle by one; if the solution circulation cycle is greater than 2, outputting the A dry powder dissolution sufficiency detection result and ending the A dry powder cyclic dissolution sufficiency detection process; if the solution circulation cycle is not greater than 2, returning to execute the A dry powder cyclic dissolution sufficiency detection process until the solution circulation cycle is greater than 2.

[0014] The above scheme solves the problem that the circulation status of the solution circulation process cannot be effectively monitored. By setting the solution circulation period to be updated only after the dissolution time meets the requirements, the irregular liquid circulation flow is converted into objective data, ensuring the accuracy of the circulation dissolution test results, thereby improving the accuracy of the A dry powder dissolution sufficiency test results.

[0015] The embodiment of the present invention also provides a system for detecting the adequacy of dissolution of dry powder A, comprising: an optical detection module, a conductivity detection module, a dissolution time recording module, a circulation control module and a dissolution circulation loop; the dissolution circulation loop is used for the cyclic dissolution process of dry powder A; the optical detection module, the conductivity detection module, the dissolution time recording module and the circulation control module are all arranged in the dissolution circulation loop; the optical detection module, the conductivity detection module and the dissolution time recording module are all electrically connected to the circulation control module; the optical detection module is used to perform real-time optical detection of the A dry powder solution in the dissolution circulation loop to obtain the light intensity detection value at the current moment; the conductivity detection module is used to perform real-time conductivity detection of the A dry powder solution in the dissolution circulation loop to obtain the solution conductivity detection value at the current moment; the dissolution time recording module is used to record the dissolution time of dry powder A in the dissolution circulation loop to obtain the dissolution time of dry powder A at the current moment; the circulation control module is used to The light intensity detection value at the current moment obtained by the optical detection module, the solution conductivity detection value at the current moment obtained by the conductivity detection module, and the A dry powder dissolution time at the current moment obtained by the dissolution time recording module are read; according to the light intensity detection value at the current moment and the solution conductivity detection value at the current moment, the light intensity change value at the current moment and the solution conductivity change value at the current moment are calculated respectively; whether the A dry powder dissolution time at the current moment meets the preset dissolution time requirement, whether the solution conductivity detection value at the current moment meets the preset qualified range requirement, and the A dry powder circulation dissolution sufficiency detection process is performed in the dissolution circulation loop; during the A dry powder circulation dissolution process, the light intensity change value of the A dry powder solution at the current moment is obtained; if the light intensity change value at the current moment is equal to 0, the solution conductivity change value at the current moment is obtained; if the solution conductivity change value at the current moment is equal to 0, the A dry powder dissolution sufficiency detection result is output, and the A dry powder circulation dissolution sufficiency detection process is ended.

[0016] The embodiment of the present invention proposes a system for detecting the adequacy of dissolution of dry powder A, wherein the dry powder A is cyclically dissolved in a dissolution cycle, and then the cyclic control module is used to control the execution of the adequacy detection process of the cyclic dissolution of dry powder A, and the optical detection module is used to optically detect the A dry powder solution to obtain the light intensity change value at the current moment, and judge whether the light intensity change value at the current moment meets the requirements. If the light intensity change value at the current moment meets the detection requirements, it means that the particle content in the corresponding solution at this time meets the requirements, and then the conductivity of the solution at this time is detected and analyzed by the conductivity detection module to obtain the solution conductivity change value at the current moment. If the solution conductivity change value at the current moment meets the detection requirements, it means that the solution has been fully dissolved. In addition, a dissolution time recording module is added to detect the dissolution time of the dry powder A, which is used to indicate that the solution has been Fully dissolved, conductivity detection value analysis is added to illustrate that the solution components are used correctly. Through the above scheme, the light intensity change value of the solution at the current moment is obtained, providing a real-time, reliable and detectable data basis. There is no need to detect the light intensity in the powder-free state. The conductivity detection is also combined to further analyze whether the solution is fully dissolved, so as to better ensure that dry powder A is fully dissolved, and avoid the problem of inaccurate analysis results of the dissolution sufficiency of dry powder A caused by only optical principle detection of the solution. Then, conductivity analysis and dissolution time analysis are performed based on the light intensity change value of the solution at the current moment. By adding multiple analysis dimensions, the problem of inaccurate analysis results of the dissolution sufficiency of dry powder A caused by only optical detection of the solution is avoided, and the accidental occurrence of the solution dissolution sufficiency detection process is prevented, and the accuracy of the dissolution sufficiency detection results of dry powder A is improved.

[0017] Furthermore, the dissolution circulation loop includes: a dry powder barrel, a flow pump and a metering water tank; the bottom of the dry powder barrel is connected to one end of the flow pump; the other end of the flow pump is connected to one end of the metering water tank; the other end of the metering water tank is connected to one end of the optical detection module; the other end of the optical detection module is connected to the top of the dry powder barrel, and the conductivity detection module is arranged between the optical detection module and the dry powder barrel; the dry powder barrel is used to store A dry powder and provide A dry powder dissolution space; the flow pump is used to provide circulating dissolution power and pump the dissolved liquid into the dry powder barrel; the metering water tank is used to measure the dissolved liquid during the circulating dissolution process of A dry powder.

[0018] Through the above scheme, a solution circulation dissolution path is provided through the dissolution circulation loop, and the A dry powder solution is pumped into the dry powder barrel through the flow pump, so that the solution flows from the bottom of the dry powder barrel to the top of the dry powder barrel, ensuring that the solution circulation dissolution is more sufficient, and can reduce the solid particles carried into the subsequent optical detection and conductivity detection, thereby ensuring the accuracy of the A dry powder dissolution. The solution is measured by the metering water tank, which can also prevent excessive liquid in the dissolution circulation loop, affecting the efficiency of the A dry powder dissolution, thereby improving the accuracy of the A dry powder dissolution adequacy test results.

[0019] Furthermore, the optical detection module includes: an optical transmitter, an optical receiver and an optical detection container; the optical detection container is configured as a cylindrical cavity; a liquid inlet and a liquid outlet are provided on the side of the cylindrical cavity, and the liquid inlet is horizontally located below the liquid outlet; the liquid inlet is connected to the conductivity detection module; the liquid outlet is connected to the metering water tank; the optical transmitter and the optical receiver are respectively arranged at two ends of the cylindrical cavity, and the optical transmitter is used to emit a detection laser, and the detection laser propagates along the axial direction of the cylindrical cavity to the optical receiver, and the detection laser is received by the optical receiver, so as to realize real-time optical detection of the A dry powder solution and obtain the light intensity detection value at the current moment.

[0020] Through the above scheme, the optical detection container is set as a cylindrical cavity, the detection surface of the laser on the solution is increased, and the reliability of the data is guaranteed. In addition, the optical transmitter and the optical receiver are arranged relative to each other, and the direction of the laser is along the axial direction of the optical detection container, ensuring that the laser propagates in a straight line in the cavity, reducing the measurement error caused by light deflection or scattering, and by setting the liquid inlet below the liquid outlet, it is guaranteed that the liquid flows from bottom to top, so that the solution can be fully dissolved, and when the solution flows into and out of the optical detection container, it will not carry more solid particles.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1 , Figure 1 A schematic diagram of a method for detecting the adequacy of dissolution of dry powder A provided in one embodiment of the present invention Figure 1 .like Figure 1 As shown, the embodiment of the present invention proposes a method for detecting the adequacy of dissolution of dry powder A, and performs a process for detecting the adequacy of cyclic dissolution of dry powder A, including steps 101 to 103, and the specific steps are as follows:

[0032] Step 101, during the cyclic dissolution process of dry powder A, obtaining the light intensity change value of the A dry powder solution at the current moment;

[0033] As an example of this embodiment, before starting the A dry powder cyclic dissolution adequacy detection process, it is necessary to pre-set the dissolution time requirement and the conductivity qualified range requirement; during the A dry powder cyclic dissolution process, according to the pre-set time interval, the A dry powder solution is optically detected in real time, and the light intensity detection value at each moment can be obtained, and then the light intensity detection value at the current moment is subtracted from the light intensity detection value at the adjacent previous moment to obtain the light intensity change value at the current moment, and then the light intensity detection value at the previous moment is subtracted from the light intensity detection value at the previous moment adjacent to the light intensity detection value at the previous moment to obtain the light intensity change value at the previous moment; in a specific embodiment, the preset dissolution time requirement is T0, the preset conductivity qualified range requirement is [c0, c1], the preset time interval is t, and the number of detections is n, (n=1,2,3...); let Y n To represent the light intensity detection value of the nth detection, Y n ={Y1, Y2, ..., Y n}, (n=1,2,3…); the current light intensity change value is ΔY n =Y n -Y n-1 , n≥3; the light intensity change value at the last moment is ΔY n-1 =Y n-1 -Y n-2 , n≥3; ΔY n Can only be calculated after optical detection at least 3 times; Y n-1 Indicates the light intensity detection value at the previous moment adjacent to the light intensity detection value at the current moment, Y n-2 Indicates the light intensity detection value at the previous moment adjacent to the light intensity detection value at the previous moment, and so on, to obtain the light intensity change value at each moment. During the dissolution cycle, the light intensity detection value at the current moment is continuously updated according to the real-time detection value. The light intensity detection value at the current moment will be updated to the light intensity detection value at the previous moment at the next moment, and the light intensity detection value detected at the next moment will be updated to the light intensity detection value at the current moment;

[0034] Step 102, if the light intensity change value at the current moment is equal to 0, then obtaining the solution conductivity change value at the current moment;

[0035] As an example of this embodiment, in the process of executing step 102, the light intensity change value of the A dry powder solution at the previous moment is obtained; the light intensity change value at the current moment and the light intensity change value at the previous moment are compared once; in the first comparison, if the light intensity change value at the current moment is less than the light intensity change value at the previous moment, the A dry powder cyclic dissolution sufficiency detection process is re-executed until the light intensity change value at the current moment is not less than the light intensity change value at the previous moment; in the first comparison, if the light intensity change value at the current moment is not less than the light intensity change value at the previous moment, the light intensity change value at the current moment is compared twice. value and the light intensity change value at the previous moment; in the secondary comparison, if the light intensity change value at the current moment is equal to the light intensity change value at the previous moment, then determine whether the light intensity change value at the current moment is equal to 0; in the secondary comparison, if the light intensity change value at the current moment is not equal to the light intensity change value at the previous moment, then re-execute the A dry powder circulation dissolution sufficiency detection process until the light intensity change value at the current moment is equal to the light intensity change value at the previous moment; if the light intensity change value at the current moment is not equal to 0, then re-execute the A dry powder circulation dissolution sufficiency detection process until the light intensity change value at the current moment is equal to 0.

[0036] In order to make the optical detection results more accurate and provide a more reliable data basis to ensure the accuracy of the judgment of the subsequent steps, the difference in the light intensity change values ​​at adjacent moments is also compared to determine whether there are still solid particles in the solution to ensure that the A dry powder solution is fully dissolved, thereby improving the accuracy of the A dry powder dissolution sufficiency detection results. For a specific implementation method, see Figure 2 , Figure 2 A schematic diagram of a method for detecting the adequacy of dissolution of dry powder A provided in one embodiment of the present invention Figure 2 ; In the process of executing step 102, by obtaining the light intensity change value at the previous moment, and first performing a comparison between the light intensity change value at the current moment and the light intensity change value at the previous moment, if the light intensity change value at the current moment is less than the light intensity change value at the previous moment, it means that the A dry powder is not fully dissolved, and it is necessary to continue the cycle dissolution; if the light intensity change value at the current moment is not less than the light intensity change value at the previous moment, it means that the A dry powder may have been fully dissolved, and the next step of judgment is executed;

[0037] Since it can only be preliminarily judged that dry powder A may be fully dissolved by comparing whether the light intensity change value at the current moment is less than the light intensity change value at the previous moment, in order to avoid the randomness of the comparison result, a secondary comparison method is also used to make the optical detection result more accurate, thereby improving the accuracy of the detection result of the adequacy of the dissolution of dry powder A. A specific implementation method is that if the light intensity change value at the current moment is not less than the light intensity change value at the previous moment, a secondary comparison is performed to see whether the light intensity change value at the current moment is equal to the light intensity change value at the previous moment. If the light intensity change value at the current moment is not equal to the light intensity change value at the previous moment, it means that the result of the first comparison is accidental, and dry powder A is not fully dissolved, and it is necessary to continue the cyclic dissolution. If the light intensity change value at the current moment is equal to the light intensity change value at the previous moment, it means that the light intensity change values ​​at two adjacent moments are consistent, and it can be further considered that dry powder A is fully dissolved, and the next step of judgment is performed;

[0038] Since the light intensity change values ​​at two adjacent moments are consistent, it only means that the difference between the light intensity detection values ​​of the two adjacent detections at the previous moment and the difference between the light intensity detection values ​​of the two adjacent detections at the current moment have the same change amount, it cannot be considered that the A dry powder is fully dissolved. In order to ensure the accuracy of the sufficient dissolution of the A dry powder solution and the final A dry powder dissolution sufficiency test results, a third comparison is required. The specific implementation method is as follows: if the light intensity change value at the current moment is equal to the light intensity change value at the previous moment, it is determined whether the light intensity change value at the current moment is equal to 0. If the light intensity change value at the current moment is not equal to 0, it means that the difference between the light intensity detection values ​​of the two adjacent detections at the previous moment and the difference between the light intensity detection values ​​of the two adjacent detections at the current moment are only consistent in change amount, and the dissolution of A dry powder has not yet stabilized, and it is necessary to continue the cyclic dissolution. If the light intensity change value at the current moment is equal to 0, it means that the light intensity change value at the previous moment is also equal to 0, which further indicates that the light intensity detection values ​​obtained by the three adjacent tests are all equal values, which is sufficient to show that the dissolution of A dry powder is stable. For details, please refer to Figure 3 , Figure 3 A schematic diagram of the dynamic change of dissolution sufficiency of a method for detecting the dissolution sufficiency of dry powder A provided in one embodiment of the present invention; at time t0, the particle content curve and the AD value of the receiving end (i.e., the received light intensity) tend to be stable, and the light intensity change value detected at subsequent times tends to be unchanged. At this time, the light detection result can be basically determined to be that the dry powder A is fully dissolved, but the result can only be considered to be fully dissolved under the detection of optical principles. In order to further ensure that the solution is fully dissolved, the next step needs to be performed;

[0039] Step 103, if the solution conductivity change value at the current moment is equal to 0, then the A dry powder dissolution sufficiency detection result is output, and the A dry powder cyclic dissolution sufficiency detection process is ended. Specifically, before executing step 103, the solution conductivity change value at the previous moment is obtained; the solution conductivity change value at the current moment and the solution conductivity change value at the previous moment are compared once; in the first comparison, if the solution conductivity change value at the current moment is not less than the solution conductivity change value at the previous moment, then the solution conductivity change value at the current moment and the solution conductivity change value at the previous moment are compared twice; in the second comparison, if the solution conductivity change value at the current moment is equal to the solution conductivity change value at the previous moment, then it is determined whether the solution conductivity change value at the current moment is equal to 0; if the solution conductivity change value at the current moment is not equal to 0, then the A dry powder cyclic dissolution sufficiency detection process is re-executed until the solution conductivity change value at the current moment is equal to 0. A specific implementation method is to obtain the solution conductivity detection value C at the previous moment m , let C m is the solution conductivity value detected at the mth time, C m ={C1, C2, ..., C m}, (m=1,2,3…); the change in solution conductivity at the current moment is ΔC m =C m -C m-1 , m≥3; the change in solution conductivity at the previous moment is ΔC m-1 =C m-1 -C m-2 , m≥3; ΔC m The calculation can only be performed after the conductivity has been tested at least 3 times; C m-1 Indicates the solution conductivity detection value at the previous moment adjacent to the current solution conductivity detection value, C m-2 Indicates the solution conductivity detection value at the previous moment adjacent to the solution conductivity detection value at the previous moment, and so on, to obtain the solution conductivity change value at each moment. During the dissolution cycle, the solution conductivity detection value at the current moment is continuously updated according to the real-time detection value. The solution conductivity detection value at the current moment will be updated to the solution conductivity detection value at the previous moment at the next moment, and the solution conductivity detection value detected at the next moment will be updated to the solution conductivity detection value at the current moment;

[0040] For further explanation, see Figure 2 , Figure 2 A schematic diagram of a method for detecting the adequacy of dissolution of dry powder A provided in one embodiment of the present invention Figure 2; Before executing step 103, by obtaining the change value of the solution conductivity at the previous moment, and first performing a comparison of the difference between the change value of the solution conductivity at the current moment and the change value of the solution conductivity at the previous moment, if the change value of the solution conductivity at the current moment is less than the change value of the solution conductivity at the previous moment, it means that although the optical principle detection result shows that the dry powder A is fully dissolved, in fact, the dry powder A is not fully dissolved, and it is necessary to continue the cyclic dissolution. If the change value of the solution conductivity at the current moment is not less than the change value of the solution conductivity at the previous moment, it means that on the basis of the optical principle detection result that the dry powder A is fully dissolved, it can be confirmed that the dry powder A may have been fully dissolved. In order to reduce the contingency of the comparison result, the next step of judgment is performed; if the change value of the solution conductivity at the current moment is not less than the change value of the solution conductivity at the previous moment, a secondary comparison is performed to see whether the change value of the solution conductivity at the current moment is equal to the change value of the solution conductivity at the previous moment. If the change value of the solution conductivity at the current moment is not equal to the change value of the solution conductivity at the previous moment, it means that the result of the one comparison is contingent, the dry powder A is not fully dissolved, and it is necessary to continue the cyclic dissolution. If the solution conductivity at the current moment is not equal to the change value of the solution conductivity at the previous moment, it means that the result of the one comparison is contingent, the dry powder A is not fully dissolved, and it is necessary to continue the cyclic dissolution. The conductivity change value is equal to the solution conductivity change value at the previous moment, indicating that the solution conductivity change values ​​at two adjacent moments are consistent. It can be further considered that dry powder A is fully dissolved and the next step of judgment is performed; however, in order to further improve the accuracy of the test results of the adequacy of the dissolution of dry powder A and prevent the problem of misjudgment of the test results due to the consistent change amount, a third comparison is required. If the solution conductivity change value at the current moment is equal to the solution conductivity change value at the previous moment, it is determined whether the solution conductivity change value at the current moment is equal to 0. If the solution conductivity change value at the current moment is not equal to 0, it is determined whether the solution conductivity change value at the current moment is equal to 0. If the change value of the solution conductivity at the current moment is equal to 0, it means that the difference between the solution conductivity detection values ​​of the two adjacent detections at the previous moment and the difference between the solution conductivity detection values ​​of the two adjacent detections at the current moment are only the same in change amount, and the dissolution of dry powder A has not yet stabilized, and cyclic dissolution needs to continue. If the solution conductivity change value at the current moment is equal to 0, it means that the solution conductivity change value at the previous moment is also equal to 0, and further indicates that the solution conductivity detection values ​​obtained in the three adjacent detections are all equal values, which is sufficient to show that dry powder A is fully dissolved not only under the detection of optical principles, but also under conductivity detection.

[0041] As a further explanation of this embodiment, if the solution conductivity change value at the current moment is equal to 0, the dissolution time of dry powder A at the current moment is obtained; if the dissolution time of dry powder A at the current moment meets the preset dissolution time requirement, the solution conductivity detection value at the current moment is judged; if the solution conductivity detection value at the current moment meets the preset qualified range requirement, the A dry powder dissolution sufficiency detection result is output, and the A dry powder cyclic dissolution sufficiency detection process is ended; specifically, after performing optical detection and conductivity detection, in order to further reduce the contingency of sufficient dissolution of dry powder A, the embodiment of the present invention also proposes to compare whether the actual dissolution time reaches the basic dissolution time to ensure that dry powder A is fully dissolved, and improve the accuracy of the A dry powder dissolution sufficiency detection result, which can be specifically The implementation method is that, under normal circumstances, when the A dry powder dissolution cycle starts, the dissolution time of the A dry powder can be recorded by an external timer, so that the dissolution time of the solution can be obtained at any time. Since the optical detection and the conductivity detection are also started synchronously, a dissolution time can also be calculated using the detection time interval. The calculated dissolution time can be used to verify or calibrate the dissolution time recorded by the external timer. Specifically, the current dissolution time T of the A dry powder is obtained, and it is judged whether the actual dissolution time (equivalent to the current dissolution time of the A dry powder) T reaches the basic dissolution time (equivalent to the preset dissolution time requirement) T0. The current dissolution time T of the A dry powder can be directly read from the external counter, and can also be obtained by calculating T 光检 =n*t, where the preset time interval is t, and the number of detections is n. If the current dissolution time T of dry powder A does not meet the basic dissolution time T0, it means that the result of the sufficiency of dissolution of dry powder A obtained in the previous step may still be accidental. If the current dissolution time T of dry powder A meets the basic dissolution time T0, it means that the cyclic dissolution time of dry powder A meets the requirement, and it can be further confirmed that the dry powder A is fully dissolved.

[0042] Since the prior art only performs optical detection on the solution to determine whether the solid particles are fully dissolved, in the actual operation process, the wrong material component to be dissolved may be circulated and dissolved due to misoperation, and only optical detection of the solution cannot confirm whether the composition of the dissolved solution is correct. Therefore, in the embodiment of the present invention, it is also proposed to detect the conductivity of the solution to ensure that the composition of the dissolved material is correct, avoid unnecessary accidents, and improve the accuracy of the A dry powder dissolution sufficiency detection result. A specific implementation method is to obtain the solution conductivity detection value C at the current moment if the light intensity change value at the current moment is equal to 0. m , to determine whether the current solution conductivity detection value c meets the preset qualified range requirements [c0, c1], see Figure 4 , Figure 4 A schematic diagram of the change in conductivity during the dissolution process of a method for detecting the dissolution sufficiency of dry powder A provided in one embodiment of the present invention; when the conductivity detection value Cm If the preset qualified range requirements [c0, c1] are not met, it means that there is an error in the dissolved material composition, then an alarm will be prompted and the A dry powder circulation dissolution adequacy detection process will be terminated. m If the preset qualified range requirements [c0, c1] are met, it means that there is no error in the solution composition, then the A dry powder dissolution adequacy test result is output, and the A dry powder cyclic dissolution adequacy test process is ended;

[0043] It is worth mentioning that in order to further improve the accuracy of the A dry powder dissolution sufficiency test result, before outputting the A dry powder dissolution sufficiency test result and ending the A dry powder cyclic dissolution sufficiency test process, the embodiment of the present invention also proposes to judge the dissolution cycle period. In order to convert the irregular liquid circulation flow into objective data, the A dry powder dissolution time at the current moment meets the preset dissolution time requirement. After that, the cycle period is judged to ensure the accuracy of the cyclic dissolution test result, thereby improving the accuracy of the A dry powder dissolution sufficiency test result; a specific implementation method is to perform a judgment on the dissolution cycle period before executing the A dry powder cyclic dissolution sufficiency test result. Before the separation detection process, the solution cycle is preset and the solution cycle s is set to 0; if the dissolution time of dry powder A at the current moment meets the preset dissolution time requirement, the solution cycle s is increased by one; if the solution cycle s is not greater than 2, the process of detecting the adequacy of the circulation dissolution of dry powder A is returned to be executed until the solution cycle s is greater than 2; if the solution cycle s is greater than 2, the result of the detection of the adequacy of the circulation dissolution of dry powder A is output, and the process of detecting the adequacy of the circulation dissolution of dry powder A is ended; when the solution cycle s is greater than 2 (the judgment threshold can also be adjusted according to the actual situation), it can further indicate that the dry powder A is fully dissolved.

[0044] The embodiment of the present invention proposes a method for detecting the adequacy of dissolution of dry powder A. The method comprises the following steps: optically detecting the solution of dry powder A, obtaining the light intensity change value at the current moment, judging whether the light intensity change value at the current moment meets the requirements, and if the light intensity change value at the current moment meets the detection requirements, it indicates that the particle content in the corresponding solution at this moment meets the requirements, and then detecting and analyzing the conductivity of the solution at this moment, obtaining the conductivity change value of the solution at the current moment, and if the conductivity change value of the solution at the current moment meets the detection requirements, it indicates that the solution has been fully dissolved. Through the above scheme, the light intensity change value of the solution at the current moment is obtained, providing a real-time and reliable detectable data basis, without the need to detect the light intensity in a powder-free state, and further analyzing whether the solution is fully dissolved in combination with the conductivity detection, thereby better ensuring that the dry powder A is fully dissolved, avoiding the problem of inaccurate analysis results of the adequacy of dissolution of dry powder A caused by only detecting the solution through optical principles, and improving the accuracy of the detection results of the adequacy of dissolution of dry powder A.

[0045] Based on the above-mentioned method for detecting the dissolution adequacy of dry powder A in this embodiment, the method is implemented in a system for detecting the dissolution adequacy of dry powder A, see Figure 5 , Figure 5 A schematic diagram of the connection of internal circuit modules of a dry powder A dissolution sufficiency detection system provided for a certain embodiment of the present invention; the dry powder A dissolution sufficiency detection system comprises: an optical detection module 1, a conductivity detection module 2, a dissolution time recording module 3, a circulation control module 4 and a dissolution circulation loop; the dissolution circulation loop is used for the A dry powder cyclic dissolution process; the optical detection module 1, the conductivity detection module 2, the dissolution time recording module 3 and the circulation control module 4 are all arranged in the dissolution circulation loop; the optical detection module 1, the conductivity detection module 2 and the dissolution time recording module 3 are all electrically connected to the circulation control module 4; the optical detection module 1 is used to perform real-time optical detection of the A dry powder solution in the dissolution circulation loop to obtain the light intensity detection value at the current moment; the conductivity detection module 2 is used to perform real-time conductivity detection of the A dry powder solution in the dissolution circulation loop to obtain the solution conductivity detection value at the current moment; the dissolution time recording module 3 is used to record the dissolution time of the A dry powder in the dissolution circulation loop to obtain the current The dissolution time of dry powder A at moment A; the cycle control module 4 is used to read the light intensity detection value at the current moment obtained by the optical detection module 1, the solution conductivity detection value at the current moment obtained by the conductivity detection module 2, and the dissolution time of dry powder A at the current moment obtained by the dissolution time recording module 3, and calculate the light intensity change value at the current moment and the solution conductivity change value at the current moment according to the light intensity detection value at the current moment and the solution conductivity detection value at the current moment, respectively, to determine whether the dissolution time of dry powder A at the current moment meets the preset dissolution time requirement, to determine whether the solution conductivity detection value at the current moment meets the preset qualified range requirement, and to perform the A dry powder circulation dissolution adequacy detection process in the dissolution circulation loop, and in the A dry powder circulation dissolution process, obtain the light intensity change value of the A dry powder solution at the current moment; if the light intensity change value at the current moment is equal to 0, then obtain the solution conductivity change value at the current moment; if the solution conductivity change value at the current moment is equal to 0, then output the A dry powder dissolution adequacy detection result, and end the A dry powder circulation dissolution adequacy detection process.

[0046] As an example of an embodiment of the present invention, the dissolution circulation loop includes: a dry powder barrel 5, a flow pump 6 and a metering water tank 7; the bottom of the dry powder barrel 5 is connected to one end of the flow pump 6; the other end of the flow pump 6 is connected to one end of the metering water tank 7; the other end of the metering water tank 7 is connected to one end of the optical detection module 1; the other end of the optical detection module 1 is connected to the top of the dry powder barrel 5, and the conductivity detection module 2 is arranged between the optical detection module 1 and the dry powder barrel 5; the dry powder barrel 5 is used to store A dry powder and provide A dry powder dissolution space; the flow pump 6 is used to provide circulating dissolution power and pump the dissolved liquid into the dry powder barrel 5; the metering water tank 7 is used to measure the dissolved liquid during the circulating dissolution process of A dry powder.

[0047] The dissolution circulation loop provides a way for the solution to circulate and dissolve. The flow pump 6 pumps the A dry powder solution into the dry powder barrel 5, so that the solution flows from the bottom of the dry powder barrel 5 to the top of the dry powder barrel 5, ensuring that the solution is circulated and dissolved more fully, and can reduce the carryover of solid particles to subsequent optical detection and conductivity detection, ensuring the accuracy of the A dry powder dissolution. The metering water tank 7 measures the solution, and can also prevent excessive liquid in the dissolution circulation loop, affecting the efficiency of the A dry powder dissolution, thereby improving the accuracy of the A dry powder dissolution adequacy test results. For a specific implementation method, see Figure 6 , Figure 6 A schematic diagram of a circulation circuit connection structure of a dry powder dissolution sufficiency detection system A provided in an embodiment of the present invention; Figure 6As shown, the dissolution circulation loop includes: a dry powder barrel 5, a conductivity detection module 2, an optical detection module 1, a first solenoid valve 8, a metering water tank 7, a flow pump 6 and a second solenoid valve 9; and the dry powder barrel 5, the conductivity detection module 2, the optical detection module 1, the metering water tank 7 and the flow pump 6 are connected, and the liquid inlet from the liquid inlet end can be input into the metering water tank 7 by controlling the opening and closing of the first solenoid valve 8, and the fully dissolved solution can be output through the liquid outlet end by controlling the opening and closing of the second solenoid valve 9; in addition, the conductivity detection module 2, the optical detection module 1 and the dissolution time recording module 3 are also electrically connected to the circulation control module 4, and the conductivity detection module 2 performs conductivity detection on the dissolved liquid in the water path. It is worth mentioning that the conductivity detection of the dissolved liquid in the water path adopts the conductivity detection method mature in the existing technology, and the optical detection module 1 performs conductivity detection on the water. The dissolving liquid in the path is optically detected; the dissolution time recording module 3 is used to monitor the time of the cyclic dissolution, which can be directly read by an external timer, and the time read by the timer can be calibrated by calculating the optical detection time; the conductivity detection module 2 is used to detect the conductivity of the solution, and the conductivity detection can be used to determine whether the overall conductivity (concentration) reaches the qualified range, corresponding to the overall ion concentration with sodium ions as the majority ions reaching the qualified range. It can not only determine whether the composition of the dissolved material is correct, but also determine whether the dry powder A is fully dissolved by comparing the difference in the change value of the conductivity at adjacent moments, as evidence of the adequacy of the dissolution, and the optical detection is combined with the conductivity detection, the dissolution time and the cycle period to detect whether all the dry powder particles are fully dissolved, corresponding to whether trace substances such as calcium chloride and magnesium chloride are fully dissolved;

[0048] An example of an embodiment of the present invention, the optical detection module 1 includes: an optical transmitter 10, an optical receiver 11 and an optical detection container 12; the optical detection container 12 is set as a cylindrical cavity; a liquid inlet 13 and a liquid outlet 14 are set on the side of the cylindrical cavity, and the liquid inlet 13 is located below the liquid outlet 14 in the horizontal direction; the liquid inlet 13 is connected to the conductivity detection module 2; the liquid outlet 14 is connected to the metering water tank 7; the optical transmitter 10 and the optical receiver 11 are respectively arranged at two ends of the cylindrical cavity, and the optical transmitter 10 is used to emit a detection laser, and the detection laser propagates along the axial direction of the cylindrical cavity to the optical receiver 11, and the optical receiver 11 receives the detection laser, so as to realize real-time optical detection of the A dry powder solution and obtain the light intensity detection value at the current moment;

[0049] The optical detection container 12 is set as a cylindrical cavity to increase the detection surface of the laser on the solution and ensure the reliability of the data. In addition, the optical transmitter 10 and the optical receiver 11 are arranged relative to each other, and the laser direction is along the axial direction of the optical detection container 12, ensuring that the laser propagates in a straight line in the cavity, reducing the measurement error caused by light deflection or scattering. The liquid inlet 13 is set below the liquid outlet 14 to ensure that the liquid flows from bottom to top, so that the solution can be fully dissolved, and when the solution flows into and out of the optical detection container, it will not carry a lot of solid particles. By improving the accuracy of the light intensity change value and improving the dissolution rate of dry powder A, the accuracy of the A dry powder dissolution sufficiency detection result is improved. For a specific implementation method, see Figure 7 , Figure 7 A schematic diagram of the structure of an optical detection module of a dry powder dissolution sufficiency detection system provided in an embodiment of the present invention; Figure 7 As shown, the main body of the optical detection container 12 is a cylindrical cavity made of quartz glass, which is corrosion-resistant, high-hardness, heat-resistant and transparent. An optical transmitter 10 and an optical receiver 11 are respectively arranged at both ends of the cylindrical cavity. The direction of the laser emitted by the optical transmitter 10 is along the axial direction of the detection container. The optical transmitter 10 provides a white light laser light source. The side wall of the main body of the optical detection container 12 is provided with a liquid inlet 13 and a liquid outlet 14, which are used to be connected to the liquid inlet pipeline and the liquid outlet pipeline respectively, that is, the liquid inlet 13 is connected to the conductivity detection module 2; the liquid outlet 14 is connected to the metering water tank 7.

[0050] As an example of an embodiment of the present invention, the circulation control module 4 not only controls the switching of each solenoid valve (such as the first solenoid valve 8 and the second solenoid valve 9) in the circulation loop, but is also electrically connected to the optical detection module 1, the conductivity detection module 2 and the dissolution time recording module 3. The circulation control module stores and receives the light intensity detection value, solution conductivity detection value and dissolution time corresponding to the optical detection module 1, the conductivity detection module 2 and the dissolution time recording module 3, and then calculates the light intensity change value and the solution conductivity change value, and sets multiple judgment processes. Finally, combined with the dissolution time and the recorded cycle period, the cyclic dissolution degree of dry powder A is judged to ensure that dry powder A is fully dissolved.

[0051] The embodiment of the present invention proposes a system for detecting the adequacy of dissolution of dry powder A, wherein the dry powder A is cyclically dissolved in a dissolution cycle, and then the cyclic control module is used to control the execution of the adequacy detection process of the cyclic dissolution of dry powder A, and the optical detection module is used to optically detect the A dry powder solution to obtain the light intensity change value at the current moment, and judge whether the light intensity change value at the current moment meets the requirements. If the light intensity change value at the current moment meets the detection requirements, it means that the particle content in the corresponding solution at this time meets the requirements, and then the conductivity of the solution at this time is detected and analyzed by the conductivity detection module to obtain the solution conductivity change value at the current moment. If the solution conductivity change value at the current moment meets the detection requirements, it means that the solution has been fully dissolved. In addition, a dissolution time recording module is added to detect the dissolution time of the dry powder A, which is used to indicate that the solution has been Fully dissolved, conductivity detection value analysis is added to illustrate that the solution components are used correctly. Through the above scheme, the light intensity change value of the solution at the current moment is obtained, providing a real-time, reliable and detectable data basis. There is no need to detect the light intensity in the powder-free state. The conductivity detection is also combined to further analyze whether the solution is fully dissolved, so as to better ensure that dry powder A is fully dissolved, and avoid the problem of inaccurate analysis results of the dissolution sufficiency of dry powder A caused by only optical principle detection of the solution. Then, conductivity analysis and dissolution time analysis are performed based on the light intensity change value of the solution at the current moment. By adding multiple analysis dimensions, the problem of inaccurate analysis results of the dissolution sufficiency of dry powder A caused by only optical detection of the solution is avoided, and the accidental occurrence of the solution dissolution sufficiency detection process is prevented, and the accuracy of the dissolution sufficiency detection results of dry powder A is improved.
