Description

Technical Field

[0001] This invention belongs to the field of titration equipment technology, specifically relating to an automatic titration system and titration method. Background Technology

[0002] Titration is a well-known method used in practice to determine the concentration of a component in a solution. Titration of various chemical components is used in practice, in which a titrant is generally added to a solution, whereby the titrant reacts with a selected component of the solution. Once the entire reactant has reacted with the known titrant, a measurable or significant change occurs, indicating that the reaction is complete. In some cases, significant changes include color changes.

[0003] Currently, most operations are still done manually. The flow rate is controlled by the experimenter manually adjusting the flow valve, and then the color is observed by the naked eye. The flow valve is then adjusted to shut off the flow of the liquid. Finally, the dosage and remaining amount are weighed to determine parameters such as color and dosage.

[0004] However, the experiment involves human intervention, such as controlling the flow rate and observing the color manually. This process is subject to numerous human factors, which can easily lead to deviations in the test results and compromise the accuracy of the data. Summary of the Invention

[0005] Based on this, this application provides an automatic titration system and titration method to solve the problems that are easily affected by human factors, which can lead to deviations in test results and make it impossible to guarantee the accuracy of data.

[0033] The technical solution adopted in this application can achieve the following beneficial effects:

[0034] 1. The titration experiment can be completed by the test personnel changing the liquid and reagent in the titration bottle and the addition bottle. The use of color recognition components and weight detection components replaces the manual observation of color changes and the corresponding amount of reagent used, reducing labor intensity and human factors, thereby improving the accuracy of the titration experiment. This solves the problem that most equipment has a complex structure and difficult manufacturing process, and many human factors can easily lead to deviations in test results and make it impossible to guarantee the accuracy of data.

[0035] 2. By automatically controlling the opening and closing of the flow rate control component and controlling the flow rate, the flow rate during the experiment is kept constant. At the same time, by manually adjusting multiple parameters such as the first standard flow rate parameter and the second flow rate parameter, the problem of the weight of the corresponding color liquid dropped into the titration bottle cannot be measured and counted due to manual adjustment of the knob is reduced.

[0036] 3. By continuously adding the reagent, different standard color parameters of the reaction in the titration bottle are identified, and the corresponding reagent dosage parameters are measured. This solves the problems of personnel being insensitive to color when conducting experiments on their own, such as prolonged observation of the titration bottle and stopping the test as soon as the color changes, which leads to errors and missing experimental data.

[0053] Please see Figures 1 to 11This application provides an automatic titration system, including: a titration device, a detection device 160, and a main server. The titration device includes an experimental component 110, a colorimetric recognition component 120, a metering component 130, and a flow rate control component 140. The experimental component 110 includes a cabinet 111, a titration bottle 112 disposed within the cabinet 111, a liquid addition bottle 113 disposed on the top of the cabinet 111, and a liquid guide tube 114 connecting the titration bottle 112 and the liquid addition bottle 113. The recognition component... The device is installed inside the cabinet 111 to identify the color inside the titration bottle 112 and acquire the color information inside the titration bottle 112; the metering component 130 is located at one end of the liquid guide tube 114 and is detachably connected to the cabinet 111, and the metering component 130 can weigh the liquid in the addition bottle 113; the flow rate control component 140 is located below the metering component 130 and connected to the outlet of the metering component 130, and the flow rate control component is used for... The flow rate of the liquid is adjusted, and the outlet of the flow rate control component 140 is located above the titration bottle 112. The detection component includes a flow rate detector 161 and a weight detector 162. The flow rate detector 161 is located at the outlet of the flow rate control component 140 and is used to acquire the flow rate information of the liquid. The weight detector 162 is electrically connected to the metering component 130 and is used to acquire weight information, which includes the weight parameters of the liquid and the weight parameters of the metering component 130. The main server includes a standard module and a judgment module. The standard module is used to respond to the operation of the test personnel and output standard color information and standard flow rate information. The input terminal of the judgment module is electrically connected to the output terminals of the colorimetric recognition component 120, the flow rate detector 161, and the weight detector 162, respectively. The output terminal of the judgment module is connected to the flow rate control component and is used to determine whether the color information is the same as the standard color information. If not, an instruction to adjust the flow rate control component 140 is output.

[0054] Specifically, the cabinet 111 is made of, but is not limited to, wooden cabinets or cabinets made of acrylic panels. The top of the cabinet 111 has a through hole, the size of which is the same as that of the liquid addition bottle 113. The liquid addition bottle 113 is funnel-shaped and is connected to the through hole by means of sealant, buckles, etc. The titration bottle 112 is made of, but is not limited to, beakers or conical flasks. The titration bottle 112 is placed inside the cabinet 111. The liquid guide tube 114 is made of the same or similar material as the burette. This application uses a combination of glass tube 133 and flexible tubing, which can be selected according to the specific needs. Several connecting rods are provided inside the cabinet 111 (not all of which are shown in the figure; they can be set according to the layout needs). The other end of the connecting rod is provided with a snap fastener, which is not limited to, snap rings, connecting ropes, Velcro, etc. The liquid guide tube 114 is detachably connected to the snap fastener.

[0055] The flow rate control component 140 employs, but is not limited to, structures such as an electromagnetic knob with a hose, or a pressing element with a hose, to adjust the inner diameter of the hose via electromagnetic means, a motor, or a telescopic rod, thereby adjusting the flow rate. Similarly, the metering component 130 employs spring scales, level sensors, etc.

[0056] The flow rate detection element 161 uses, but is not limited to, a flow meter to obtain the amount of liquid medicine flowing through per unit time, thereby calculating the flow rate. The flow rate detection element 161 is set at the outlet of the metering component 130. The weight detection element 162 is set inside the metering component 130. The liquid medicine is weighed by the metering component 130, and then the weight detection element 162 records the weight.

[0057] The judgment module includes a flow rate comparison unit and a color comparison unit. The standard module also includes a standard flow rate unit and a standard color unit. The standard flow rate unit stores a first standard flow rate parameter, a second standard flow rate parameter, ..., an nth standard flow rate parameter. The standard color unit includes a first standard color parameter, a second standard color parameter, ..., an nth standard color parameter. The flow rate comparison unit receives the flow rate information and standard flow rate parameters acquired by the flow rate detection device 161. By comparing the flow rate information with the standard flow rate parameters, it outputs information on whether the flow rate control component 140 is turned on and the opening threshold. The color comparison unit receives the color information from the colorimetric recognition component 120 and compares it with the first standard color parameter. If they are the same, it outputs the first standard color parameter, the corresponding flow rate parameter, and the corresponding drug weight parameter. Then, the drug continuously flows into the titration bottle 112, and the color comparison unit repeatedly compares the color information with the second standard color parameter, the third standard color parameter, ..., the nth standard color parameter. It outputs the flow rate information and drug weight parameter corresponding to the second standard color parameter, the third standard color parameter, ..., the nth standard color parameter, respectively.

[0058] Further, the experimenter removes the titration bottle 112 from the cabinet 111, places the experimental liquid inside, puts it back into the cabinet 111, and closes the cabinet 111; the automatic titration system is turned on, and the liquid is poured from the addition bottle 113. The weight detection element 162 acquires the weight parameter of the metering component 130 and adjusts it to 0 (similar to the process of placing a tray on an electronic scale to tare); the liquid enters the metering component 130 from the addition bottle 113 along the liquid guide tube 114. At this time, the weight detection element 162 acquires the weight parameter of the liquid (the first weight parameter) and records it; the flow rate comparison unit compares the actual flow rate information (the flow rate information feedback flow rate is 0 at this time) with the first standard flow rate parameter (adjusted according to the experimental requirements, for example, the first standard flow rate parameter is 0.5 mL / s). If the actual flow rate information is less than the first standard flow rate parameter, the flow rate control component 140 is adjusted to adjust its flow rate to the first standard flow rate parameter.

[0059] After the above steps, the liquid medicine flows through the flow rate control component 140 into the titration bottle 112, and then reacts with the liquid in the titration bottle 112 to change color. At this time, the color recognition component 120 identifies the color of the mixture in the titration bottle 112 and obtains the color information. The color comparison unit compares whether the color information and the first standard color parameter are the same: if they are the same, it outputs the first standard flow rate parameter and the liquid medicine weight parameter (the second weight parameter) corresponding to the first standard color parameter; otherwise, it compares whether the color information and the second standard color parameter are the same: if they are the same, it outputs the first standard flow rate parameter and the liquid medicine weight parameter (the third weight parameter) corresponding to the second standard color parameter; otherwise, it repeats the above steps until the comparison results are the same.

[0060] The liquid medicine continuously enters the titration bottle 112 and reacts with the liquid. The color recognition component 120 will acquire several color information, such as the first color parameter, the second color parameter, ... the nth color parameter. After comparing the first color parameter, the comparison unit continues to compare the second color parameter until the (n-1)th color parameter is the same as the nth color parameter.

[0061] When the (n-1)th color parameter is the same as the nth color parameter, the flow rate information is obtained, and it is determined whether the flow rate information is less than the first standard flow rate parameter (that is, the liquid in the metering component 130 is gradually used up, and the flow rate decreases, causing it to be lower than the first standard flow rate parameter); if so, an instruction is issued to turn off the color recognition component 120 and the flow rate control component 140, and to obtain the liquid weight parameter (n+2th weight parameter).

[0062] By retrieving the data, the experimenters can find out the following: under the first standard flow rate parameter, the second weight parameter corresponds to the color when it changes to the first standard color, the third weight parameter corresponds to the color when it changes to the second standard color, ..., the (n+1)th weight parameter corresponds to the color when it changes to the nth standard color, and finally the (n+2)th remaining weight parameter.

[0063] The technical solution of the automatic titration system adopted in this application can achieve the following beneficial effects:

[0064] 1. The titration experiment can be completed by the test personnel changing the liquid and reagent in the titration bottle 112 and the liquid addition bottle 113. The color recognition component 120 and the weight detection component 162 replace the manual observation of color changes and the corresponding amount of reagent used, reducing labor intensity and human factors, thereby improving the accuracy of the titration experiment. This solves the problem that most equipment has a complex structure and difficult manufacturing process, and many human factors can easily lead to deviations in test results and make it impossible to guarantee the accuracy of data.

[0065] 2. By automatically controlling the opening and closing of the flow rate control component 140 and controlling the flow rate, the flow rate during the experiment is kept constant. At the same time, by manually adjusting multiple parameters such as the first standard flow rate parameter and the second flow rate parameter, the problem of the weight of the corresponding color liquid dropped into the titration bottle 112 cannot be measured and counted due to manual adjustment of the knob is reduced.

[0066] 3. By continuously adding the reagent, different standard color parameters of the reaction in the titration bottle 112 are identified, and the corresponding reagent dosage parameters are measured. This solves the problems of errors and missing experimental data caused by personnel's insensitivity to color when conducting experiments on their own and staring at the titration bottle 112 for a long time, or stopping the experiment as soon as the color changes.

[0067] In the above scheme, in order to facilitate the retrieval of data by the test personnel, the titration device also includes a display component, which is set on the top of the cabinet 111; the main server includes an output module, the input end of which is connected to the output end of the color recognition component 120, the output end of the flow rate detection component 161, the output end of the weight detection component 162 and the output end of the standard module, respectively, for outputting the weight information and flow rate information corresponding to the color information to the recognition component.

[0068] The vertical projection of the titration bottle 112 falls within the recognition range of the colorimetric recognition component 120. The colorimetric recognition component 120 is housed within a cabinet 111, which also contains several lighting lamps. A light-shielding plate (not shown in the figure, but to be arranged as needed) is positioned on the opposite side of the colorimetric recognition component 120. The light-shielding plate is adjusted according to the color of the experimental reagent, such as white or black. The colorimetric recognition component 120 adopts, but is not limited to, a colorimetric recognition device for a capacitor sleeve disclosed in Chinese Utility Model Patent Publication No. CN208478162U, where the colorimetric recognizer can be the colorimetric recognition component 120 of this application; the specific structure will not be described further. The light-shielding plate is connected to the cabinet 111 or positioned on one side of the titration bottle via clips, bolts, or other means. The lighting lamps are housed within the cabinet 111 and are powered by a series-connected power supply or by batteries. By using the colorimetric recognition component 120, human eye recognition is replaced, improving the accuracy of the recognition.

[0069] Meanwhile, the display component adopts, but is not limited to, tablet computers, electronic displays, etc. This application uses a display, and the display component is set on the top of the cabinet 111; the input end of the output module is connected to the output end of the judgment module, and the output end of the output module is connected to the display component. The display component is used to display the second weight parameter corresponding to the color when the color changes to the first standard color, the third weight parameter corresponding to the color when the color changes to the second standard color, ..., the (n+1)th weight parameter corresponding to the color when the color changes to the nth standard color, and the last remaining (n+2)th weight parameter under the condition of the first standard flow rate parameter in the titration experiment.

[0070] By setting up display components and output modules, testers only need to observe the monitor to know that the liquid flows from the liquid guide tube 114 into the titration bottle 112, and the color recognition component 120 recognizes and feeds back to the monitor in real time. Testers can watch the entire process of color change in the titration bottle 112 on the monitor, making the operation simpler and more convenient.

[0071] In one embodiment of this application, to address the issue of manual cleaning of the experimental equipment after the experiment, the titration device further includes a backwashing assembly 150.

[0072] The main server also includes a backwashing module. The input of the backwashing module is connected to the weight detection element 162, the pressure sensor 155, the color recognition component 120, and the judgment module. The output of the backwashing module is connected to the backwashing component 150. The backwashing module acquires at least two color information and determines whether the at least two color information are the same. If they are, it acquires the liquid weight parameter and determines whether the liquid weight parameter is greater than 0. If not, it issues a command to turn on the backwashing component 150. At the same time, it acquires the pressure parameter and determines whether the pressure parameter reaches a threshold. If so, it issues a command to turn off the backwashing component 150.

The size of the driving wheel 1595 is smaller than the size of the missing gear 1592. The missing gear 1592 meshes with both the driving wheel 1595 and the driven wheel 1582.

[0075] Furthermore, open cabinet 111, and place titration bottle 112 (containing experimental reagents) and collection bottle 157 on both sides of rotating disk 151 to form a central symmetry; after placement, close cabinet 111, and then the experimenter turns on the automatic titration system and puts the required reagent into addition bottle 113. The reagent enters the liquid guide tube 114 along addition bottle 113, and then enters titration bottle 112; perform the above titration steps. After the above steps are completed (when the (n-1)th color parameter is the same as the nth color parameter, obtain the flow rate information and determine whether the flow rate information is less than the first standard flow rate parameter).

[0076] When the (n-1)th color parameter is the same as the nth color parameter, obtain the flow rate information and determine whether the flow rate information is less than the first standard flow rate parameter: if so, issue an instruction to close the flow rate control component 140 and obtain the liquid weight parameter (n+2th weight parameter);

[0077] The system acquires the weight parameter of the liquid medicine (the (n+2)th weight parameter) and determines whether it is greater than 0. If so, it activates the flow rate control component 140 to make the flow rate information the same as the nth standard flow rate parameter (maximum flow rate). If not, it activates the motor and the clean water component 156 within the backwash component 150. When the motor and clean water component 156 within the backwash component 150 are activated, the motor rotates forward, driving the drive wheel 1595 to rotate. Simultaneously, the missing gear 1592 begins to rotate, compressing the return spring. The missing gear 1592 drives the driven wheel 1582, which meshes with it, thereby causing the rotating disk 151 to rotate. When the collection bottle 157 is located below the liquid guide tube 114, the motor continues to rotate, and the driven wheel 1582 compresses and releases the movable teeth 1594 repeatedly, causing the missing gear 1592 to stop rotating. The clean water component 156 cleans the liquid addition bottle 113 and the liquid guide tube 114 with clean water, and then the waste liquid enters the collection bottle 157.

[0078] Obtain pressure parameters and determine if they reach the threshold. If so, shut down the motor in the backwash assembly 150, the clean water assembly 156, and the detection devices 160 (weight detection element 162 and flow rate detection element 161) and the color recognition assembly 120. When shutting down the motor in the backwash assembly 150, the motor reverses, causing the missing gear 1592 to rotate 180° and reach the movable tooth 1594 at the other end, automatically shutting down the motor (this can be achieved through delayed shutdown, power-off shutdown, or opening the cabinet 111 to disconnect the motor power supply). Open the cabinet 111 and remove the collection bottle 157 and the titration bottle 112 to complete the entire test.

[0079] 1. By setting up a water purification component 156 to rinse the liquid addition bottle 113 and the liquid delivery tube 114 with clean water, the residual liquid in the liquid delivery tube 114 and the liquid addition bottle 113 is cleaned out, which solves the problem that after titration, some solution is easy to remain in the titration container, and direct subsequent titration will affect the accuracy of the next test result.

[0080] 2. By setting a rotating disk 151, the positions of the titration bottle 112 and the collection bottle 157 can be changed, making cleaning simpler and more convenient. Furthermore, by using a motor with a missing gear 1592 and other meshing mechanisms, the problem of the rotating angle of the rotating disk 151 being uncertain, which caused the collection bottle 157 and the liquid guide tube 114 to not be aligned, can be solved.

[0081] Based on the above scheme, the water purification component 156 includes a pumping component 1561, a frame 1562, and a nozzle 1563. The frame 1562 is disposed on the top of the cabinet 111 and located on one side of the liquid filling bottle 113. The nozzle 1563 is disposed on the frame 1562. The outlet of the pumping component 1561 is connected to the inlet of the nozzle 1563, and the inlet of the pumping component 1561 is connected to a water source.

[0082] The frame 1562 is a 7-shaped support frame made of stainless steel, plastic and other materials. The nozzle 1563 is set at one end of the frame 1562 and above the liquid filling bottle 113. A spherical seat is set between the frame 1562 and the nozzle 1563. The inlet of the pump 1561 is connected to the water source, and the outlet of the pump 1561 is connected to the inlet of the nozzle 1563. The pump 1561 is, but is not limited to, a water pump. After receiving the instruction to open the backwash assembly 150, the pump 1561 rinses different positions of the liquid filling bottle 113 through the nozzle 1563. After rinsing is completed, the pump 1561 is turned off. The operation is simpler and more convenient.

[0083] In another embodiment of the above scheme, a water guide ring is provided at the end of the frame 1562 away from the cabinet 111. The water guide ring is provided with a water inlet and several water outlets. The water inlet of the nozzle 1563 is connected to the water outlet of the water guide ring, and the water inlet of the water guide ring is connected to the water outlet of the pumping component 1561.

[0084] The water guide ring is a hollow ring, and its size is the same as that of the liquid addition bottle 113. The water guide ring is provided with several water outlets, each of which is connected to a nozzle 1563. The nozzles 1563 are set at an angle, and the spray direction of the nozzles 1563 coincides with the extension direction of the side wall of the liquid addition bottle 113. Moreover, the spray direction of each nozzle 1563 is pointing towards the center of the liquid addition bottle 113. The water inlet of the water guide ring is connected to the pumping component 1561, and the water guide ring is detachably connected to the bracket by means of snap-fit ​​or other means. By turning on the pumping component 1561, several nozzles 1563 spray clean water simultaneously, so as to clean the side wall of the liquid addition bottle 113 without dead angles. The operation is simple and convenient, requiring no operation by the test personnel, thus reducing the labor intensity of the test personnel.

[0085] In another embodiment of this application, the rotating disk 151 is provided with a first groove 152 and a second groove 154, the first groove 152 is configured to cooperate with the titration bottle 112, and the second groove 154 is configured to cooperate with the collection bottle 157.

[0086] The dimensions of the first groove 152 and the second groove 154 are slightly larger than the dimensions of the bottom of the titration bottle 112 and the collection bottle 157. At least two limiting push plates and springs are provided on the periphery of the first groove 152 and the second groove 154. By pushing the limiting push plates, the springs are compressed, and the titration bottle 112 is placed into the first groove 152. Then, the springs extend and drive the limiting push plates to lock onto the periphery of the titration bottle 112, thereby completing the fixation. The collection bottle 157 is placed in the second groove 154, and the operation is the same as that of the first groove 152. By setting the first groove 152 and the second groove 154 on the rotating disk 151, the titration bottle 112 and the collection bottle 157 are fixed, which solves the problem of displacement of the titration bottle 112 and the collection bottle 157 when the rotating disk 151 rotates, resulting in splashing of medicine and waste liquid.

[0087] In the above scheme, a magnetic stirring base 153 is provided in the first groove 152, and a magnetic stir bar is provided in the titration bottle 112. The magnetic stirring base 153 is coupled to the magnetic stir bar.

[0088] Specifically, to ensure uniform mixing of the reagent in the titration bottle 112 and the added liquid medicine, a magnetic stirring base 153 is provided at the bottom of the first groove 152, and a magnetic stir bar is provided inside the titration bottle 112. The specific structure adopts, but is not limited to, the electromagnetic stirrer disclosed in Chinese Utility Model Patent Publication No. CN2176821Y; details will not be elaborated here. A pressure sensor 155 is provided in the second groove 154. The pressure sensor 155 is used to acquire the pressure parameters of the collection bottle 157 and feed them back to the backwashing module.

[0089] In another embodiment of this application, the flow rate control component 140 includes a flow rate control element 141 and a connecting hose 142. The connecting hose 142 is disposed at one end of the liquid guide tube 114, and the other end of the connecting hose 142 extends into the titration bottle 112. The flow rate control element 141 is disposed inside the cabinet 111 and is penetrated by the connecting hose 142. The flow rate control element 141 can squeeze the connecting hose 142 to control the flow rate within the connecting hose 142.

[0090] The speed control component 141 adopts, but is not limited to, a speed control structure used in medical infusion tubing, a knob-type structure, etc., the specific structure of which will not be described in detail here. This application further adopts the following configuration: the speed control component 141 includes a housing 1411, an auxiliary wheel 1412, and a cam 1413. The housing 1411 is disposed within the cabinet 111 via a connecting rod. The connecting hose 142 passes through the housing 1411. The cam 1413 has teeth on its base circle. The cam 1413 is rotatably connected to the housing 1411 and engages with the connecting hose 142. The auxiliary wheel 1412 is rotatably connected to the housing 1411 and meshes with the toothed side of the cam 1413. A rotating rod is disposed at the center of the auxiliary wheel 1412. The rotating rod is connected to a drive mechanism (the drive mechanism adopts, but is not limited to, motor drive, gear meshing, friction wheel pulley drive, etc.).

[0091] Furthermore, the experimenter opens cabinet 111, places titration bottle 112 inside cabinet 111, and then connects liquid guide tube 114, connecting hose 142, titration bottle 112, and liquid addition bottle 113. Upon receiving the flow rate control component 140, the speed control component 141 is adjusted, activating the drive motor connected to the rotating rod to rotate the rotating rod, causing the auxiliary wheel 1412 on the rotating rod to rotate. The rotation of the auxiliary wheel 1412 causes the cam 1413 meshing with it to rotate. 3. The protruding end squeezes the connecting hose 142, reducing the flow rate through the connecting hose 142; the medicine is poured from the liquid addition bottle 113, and the medicine enters the connecting hose 142 along the liquid guide tube 114. Then the flow rate changes and slows down, so that less medicine enters the titration bottle 112 and the dripping time is longer; if rapid flow into the titration bottle 112 is required, the rotating rod is rotated in the opposite direction to release the connecting hose 142 from the protruding end of the cam 1413, thereby increasing the flow rate through the connecting hose 142.

[0092] The drive motor is electrically connected to the main server. The judgment module issues start and stop commands, obtains flow rate information and standard flow rate information, and determines whether the flow rate information is equal to the standard flow rate information.

[0093] If not, issue a command to start the drive motor; if yes, issue a command to stop the drive motor.

[0094] The technical solution of this application can achieve the following beneficial effects:

[0095] 1. By setting the speed control component 141, the flow rate of the liquid in the connecting hose 142 is adjusted to reduce the flow rate. At the same time, the less liquid drips into the titration bottle 112, the more accurate the calculated usage will be. In addition, the dosage corresponding to the color that runs through the titration bottle 112 is more accurate. This solves the problem that the flow rate of some equipment cannot be controlled, resulting in low measurement accuracy and making it difficult to widely use.

[0096] 2. By adjusting the flow rate in the tubing, the overall applicability is improved to meet the requirements of different drug titration experiments. At the same time, by adjusting the flow rate in the tubing, excess drug in the addition bottle 113 can be quickly flowed into the titration bottle 112 for waste liquid treatment, making the operation simpler and more convenient.

[0097] Based on the above scheme, the metering component 130 includes a high-precision spring tension gauge 131, a transfer bottle 132, and a sliding sleeve 134. The sliding sleeve 134 is fixed inside the cabinet 111 and located below the liquid addition bottle 113. A limit ring is provided at the bottom of the sliding sleeve 134. The transfer bottle 132 is slidably disposed inside the sliding sleeve 134, and the top of the transfer bottle 132 is not lower than the limit ring. One end of the liquid guide tube 114 is located above the transfer bottle 132. A glass tube 133 and a solenoid valve are provided at the bottom of the transfer bottle 132. The other end of the glass tube 133 is located above the titration bottle 112. One end of the high-precision spring tension gauge 131 is fixedly connected inside the cabinet 111, and the other end is connected to the transfer bottle 132 for measuring the weight of the transfer bottle 132.

[0098] Specifically, the metering component 130 is positioned above the flow control component 140 and includes a high-precision spring tension gauge 131, a transfer bottle 132, and a sliding sleeve 134. The sliding sleeve 134 is fixed to one end of the connecting rod, and a limit ring is provided at the bottom of the sliding sleeve 134. The transfer bottle 132 is fitted inside the sliding sleeve 134, and one end of the liquid guide tube 114 is located above the transfer bottle 132. A glass tube 133 and a solenoid valve are provided at the bottom of the transfer bottle 132, and the other end of the glass tube 133 extends into the titration bottle 112. One end of the high-precision spring tension gauge 131 is fixedly connected to the connecting rod, and the other end is connected to the transfer bottle 132. In the initial state, the high-precision spring tension gauge 131 pulls the transfer bottle 132, causing the bottom of the transfer bottle 132 to move away from the limiting ring of the sliding sleeve 134, and the top of the transfer bottle 132 to extend beyond the sliding sleeve 134. The value on the high-precision spring tension gauge 131 is adjusted to zero, and the solenoid valve is closed. After all the liquid medicine enters the transfer tank along the guide tube 114, it drives the transfer bottle 132 downward, thereby pulling the high-precision spring tension gauge 131 to extend. The first value of the high-precision spring tension gauge 131 is recorded. The solenoid valve is opened, and when the color in the titration bottle 112 changes to the preset color, the solenoid valve is closed, and the second value on the high-precision spring tension gauge 131 is recorded. The amount of liquid medicine used can be determined by comparing the first and second values.

[0099] 1. By setting the metering component 130, the tester can control the start and stop of the metering component 130 while observing the color inside the titration bottle 112. This makes the operation more convenient and the control of the amount used more precise. It solves the problem that many automatic titrators still only report the change in titration color, and cannot measure the amount of liquid used. Manual measurement of volume, weight, etc. is prone to splashing, overflowing or accidental spillage, which leads to the difference between the recorded data and the actual amount used.

[0100] 2. By setting it inside the cabinet 111, the problem of incorrect dosage of medicine caused by human intervention is reduced. At the same time, by manually controlling the solenoid valve, it can be closed as soon as the color in the titration bottle 112 reaches the preset color. Then, the value of the high-precision spring tension gauge 131 is observed and the calculation is performed based on the value. The operation is simple and convenient.

[0101] Please see Figure 12 In another embodiment of this application, in order to meet the titration experiments under different temperature conditions, a heating component 170 is provided on the rotating disk 151. The heating component 170 adopts, but is not limited to, a heating wire coiled around the periphery of the titration bottle 112, a heating sleeve wrapped around the outside of the titration bottle 112, etc. This application provides a preferred solution, in which the heating component 170 includes an arc-shaped clamping plate 173 symmetrically arranged on both sides of the first groove 152, an elastic push rod 172, and a fixing block 171. The fixing blocks 171 are symmetrically arranged on the fixing disk, and the line connecting the fixing blocks 171 is perpendicular to the recognition direction of the colorimetric recognition component 120. One end of the elastic push rod 172 is connected to the fixing block 171, and the other end is connected to the arc-shaped clamping plate 173, for driving the arc-shaped clamping plate 173 to reciprocate along a preset direction. A heating element is provided inside the arc-shaped clamp 173 to heat the titration bottle. The heating element is not limited to hot water heating or heating wire heating, preferably a heating wire with constant temperature function. The end of the heating wire away from the fixing block 171 is provided with heat transfer cotton, which is in contact with the outer surface of the titration bottle. The elastic push rod 172 is a common compression rod or spring rod. For example, the elastic push rod 172 includes an inner rod, an outer rod and a compression spring. One end of the compression spring is connected to the end of the inner rod, and the other end of the inner rod is connected to the fixing block 171. The outer rod is sleeved on the inner rod, and the top of the inner wall of the outer rod away from the fixing block 171 is connected to the compression spring. The compression of the outer rod causes the compression spring to relax. When there is no external force, the compression spring returns to its original position, driving the outer rod to move away from the fixing block 171.

[0102] Furthermore, the arc-shaped clamps 173 are symmetrically clamped on both sides of the titration bottle 112, and gaps are left at both ends of the two arc-shaped clamps 173. These gaps are used by the color recognition component 120 to identify the color of the liquid in the titration bottle 112. When the tester places the titration bottle 112, the fully extended elastic push rod 172 is pushed to both sides (towards the fixing block 171) until the projection of the arc-shaped clamps 173 is located on both sides of the first groove. The titration bottle 112 is then quickly placed in the first groove 152, and the elastic push rod 172 is slowly released so that the arc-shaped clamps 173 are symmetrically clamped on both sides of the titration bottle 112 to heat the titration bottle 112. Conversely, the operation of removing the titration bottle 112 is similar to the above operation and will not be described again. The arc-shaped clamp 173 is equipped with a temperature control device, and the temperature can be adjusted according to actual needs, such as temperature control for tea bar machines, temperature-adjustable hand warmers, etc. These are products that are already on the market, and the specific adjustments and structures will not be described in detail. For easy control, it can be adjusted manually, or the temperature control device can be electrically connected to the display component, and the operator can adjust the temperature control device from the display component.

[0103] An automated titration method, applied to any of the automated titration systems described above, the automated titration system further comprising a backwashing assembly 150, the automated titration method comprising the following steps:

[0104] Step S10: Obtain the weight parameter of the metering component 130 and adjust it to 0; the weight detection component 162 performs weight detection on the metering component 130 without liquid medicine. At this time, the metering component 130 has its own weight. By tareing the goods, the weight parameter of the metering component 130 is adjusted to 0.

[0105] Step S20: Obtain the weight parameter of the liquid medicine and determine whether the weight parameter of the liquid medicine is greater than 0; the liquid medicine enters the metering component 130 from the liquid addition bottle 113, the weight detection component 162 obtains the first liquid medicine weight parameter (referred to as the first weight parameter), and determines whether the first weight parameter is greater than 0, that is, determines whether there is liquid medicine in the metering component 130.

[0106] If yes, then activate the flow rate control component 140; if there is liquid medicine, activate the flow rate control component 140 to allow the liquid medicine to flow out from the metering component 130 and into the titration bottle 112; if not, continue the detection.

[0107] Step S30: Obtain flow velocity information and standard flow velocity information, and determine whether the flow velocity information is equal to the standard flow velocity information; obtain flow velocity information through flow velocity detection device 161, and the experimenter selects a standard flow velocity parameter within the standard flow velocity information (the first standard flow velocity parameter is the minimum flow velocity, and the nth standard flow velocity parameter is the maximum flow velocity), preferably the first standard flow velocity parameter. Simply put, it is to determine whether the flow velocity control component 140 is turned on.

[0108] If not, an instruction to adjust the flow rate control component 140 is issued; if not enabled, the flow rate control component 140 is enabled and the flow rate of the flow rate control component 140 is adjusted to be the same as the first standard flow rate parameter.

[0109] Step S40: Obtain color information and standard color information, and determine whether the color information is the same as the standard color information; at this time, the liquid has entered the titration bottle 112 and reacted and the color changed at the same time. The color information of the first color change (referred to as the first color parameter) identified by the colorimetric recognition component 120 is compared with the standard color information (there are several standard color information, similar to a color reference table), and the one that is the same as the first color parameter is the first standard color parameter.

[0110] If yes, an instruction to obtain the liquid weight parameter is issued, and the color information and the corresponding liquid weight parameter are recorded; when the first color parameter is the same as the first standard color parameter, the liquid weight parameter (hereinafter referred to as the second weight parameter) in the metering component 130 is obtained and output, and the liquid changes color to the first color parameter (first standard color parameter) at the flow rate of the first standard flow rate parameter, and the remaining amount of liquid is the second weight parameter (this parameter is calculated to obtain the final dosage, and the dosage of liquid is equal to the first weight parameter minus the second weight parameter); if no, the first color parameter continues to be compared with the standard color parameter in the standard color information until they are the same.

[0111] Step S50: Obtain at least two color information and determine whether the color information is the same: Simply put, the color recognition component 120 continuously obtains color information, including the first color parameter, the second color parameter, ..., the nth color parameter. Each color information needs to be compared with the standard color information to obtain the corresponding standard color information; at this time, it is determined whether the (n-1)th color parameter is the same as the nth color parameter.

[0112] If yes, the flow rate control component 140 is turned off, and the weight parameter of the liquid is output; if the same, it means that the color of the liquid does not change no matter how much liquid is added to the titration bottle 112. At this time, the flow rate control component 140 is turned off to prevent the liquid from flowing from the metering component 130 into the titration bottle 112, and the weight of the remaining liquid in the metering component 130 is obtained by the weight detection component 162.

[0113] If not, repeat step S40; if the (n-1)th color parameter is not the same as the nth color parameter, continue the comparison until they are the same.

[0114] Step S60: Obtain the weight parameter of the liquid medicine and determine whether the weight of the liquid medicine is greater than 0; after the (n-1)th color parameter is the same as the nth color parameter, obtain the (n+1)th weight parameter of the liquid medicine and determine whether it is greater than 0, that is, determine whether there is still liquid medicine in the metering component 130.

[0115] If so, an instruction to adjust the flow rate control component 140 is issued; if there is liquid medicine in the metering component 130, the flow rate control component 140 is turned on so that the flow rate information obtained by the flow rate detection component 161 is the same as the nth flow rate parameter; that is, all the liquid medicine in the metering component 130 is put into the titration bottle 112.

[0116] If not, a command to open the backwash assembly 150 is issued; if there is no medicine in the metering assembly 130, the backwash assembly 150 is opened directly, and the liquid addition bottle 113, the liquid guide tube 114, the metering assembly 130, and the flow rate control assembly 140 are cleaned through the backwash assembly 150.

[0117] Step S70: Obtain pressure parameters and determine whether the pressure parameters have reached the threshold. Obtain pressure parameters through the pressure sensor 155 below the collection bottle 157 and determine whether the pressure parameters have reached the manually set threshold (the threshold is the pressure parameter when the collection bottle 157 is three-quarters full, which can be adjusted according to needs).

[0118] If so, the backwash assembly 150 will be shut down, and the automatic titration system will be turned off. If the weight in the collection bottle 157 reaches the threshold of the pressure parameter, all systems and equipment will be shut down to complete the entire titration experiment.

[0119] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
