[0019] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0020] A magnesium ore analysis titration box, such as Figure 1-5As shown, the system includes: a housing 10, a heating base 11, a reaction flask 12, a mounting cover 13, a lifting mechanism, a connecting base 14, a stirring assembly, a titration vessel 15, a syringe pump 16, a glass electrode 17, a temperature sensor 18, and an exhaust system. The heating base 11 is located inside the housing 10, and the reaction flask 12 is placed in the placement slot 19 of the heating base 11, with the mounting cover 13 at the top opening of the reaction flask 12. The lifting mechanism is located inside the housing 10, and the moving end of the lifting mechanism is connected to the connecting base 14. The stirring assembly is located on the connecting base 14, and the working end of the stirring assembly passes through the mounting cover 13 and is embedded in the reaction flask 12. The titration vessel 15 is located on the top of the housing 10, and the outlet of the titration vessel 15 is connected to the input end of the syringe pump 16, while the output end of the syringe pump 16 is connected to the reaction flask 12. One end of the glass electrode 17 and the temperature sensor 18 are respectively embedded in the reaction flask 12. The exhaust system is located on one side of the housing 10.

[0021] Using the above structure, the operator opens the door of the chamber 10, places the reaction flask 12 containing the pretreated magnesium ore sample into the placement slot 19 of the heating base 11, covers the top opening of the reaction flask 12 with the mounting cap 13, and inserts the temperature sensor 18. The lifting mechanism drives the connecting base 14 and the stirring assembly and glass electrode 17 fixed on the connecting base 14 to move downwards, so that the working end of the stirring assembly, the sensing end of the glass electrode 17 and the drip tube 29 pass through the mounting cap 13 and are inserted into the reaction flask 12, and then the lifting operation stops. After closing the chamber door and setting the reaction temperature, titration rate and pH endpoint value for this titration analysis, the syringe pump 16, the heating base 11 and the stirring assembly are started to operate, thereby uniformly heating the reaction flask 12 and uniformly stirring the solution in the reaction flask 12, so that it is heated evenly and reacts fully. During the titration, the glass electrode 17 continuously monitors the pH value of the solution in the reaction flask 12. When the pH value is detected to reach the titration endpoint, the syringe pump 16 stops working, reducing human titration errors. Furthermore, harmful gases generated during the reaction are discharged through the exhaust system, thereby preventing the accumulation of harmful gases from interfering with the pH measurement and thus affecting the determination of the titration endpoint.

[0022] Specifically, by performing titration within the chamber 10, harmful gases generated during the titration process can be isolated, protecting the health of operators and reducing the amount of harmful gases inhaled by operators.

[0023] Specifically, the reaction flask 12 is uniformly heated by the heating base 11 and continuously stirred by the stirring assembly to ensure that the magnesium ore sample and reagents react fully and that the reaction conditions are uniform and consistent. In addition, the glass electrode 17 and the temperature sensor 18 monitor the pH value and temperature in real time during the reaction process, thereby ensuring the reliability of the analysis results.

[0024] Specifically, ventilation holes and wiring holes are reserved on the rear side of the enclosure 10.

[0025] Specifically, the magnesium ore sample is a sample in which the magnesium ore has been ground into powder beforehand.

[0026] Specifically, the heating base 11 is equipped with a heating element located at the bottom of the placement groove 19. When the heating element is powered on, it heats the bottom of the placement groove 19, thereby achieving the purpose of uniformly heating the bottom of the reaction flask 12.

[0027] In an embodiment of this utility model, the lifting mechanism includes: a support base 20, an electric push rod 21, a slide groove 22, and a slider 23; the support base 20 is disposed inside the housing 10, and the support base 20 is provided with a slide groove 22; the slider 23 is connected to the connecting seat 14, the electric push rod 21 is fixed to the top of the support base 20, the telescopic end of the electric push rod 21 is connected to the slider 23, and the slider 23 is embedded in the slide groove 22.

[0028] The electric push rod 21 extends and retracts, causing the connecting seat 14 to move up and down, while the slider 23 moves along the slide groove 22, which serves as a guide to prevent the connecting seat 14 from shifting when it moves up and down.

[0029] In an embodiment of this utility model, the stirring assembly includes: a motor 24, a stirring shaft 25, and a connecting cover 26; the motor 24 is fixed on the connecting seat 14, the output end of the motor 24 is connected to the stirring shaft 25, and the stirring shaft 25 is embedded in the reaction flask 12; the mounting cover 13 is provided with a movable port 27, the connecting cover 26 is rotatably connected to the stirring shaft 25, and the connecting cover 26 is located at the movable port 27.

[0030] The motor 24 drives the stirring shaft 25 to rotate, accelerating the mixing of the solution in the reaction flask 12 and ensuring a complete reaction. The connection cover 26 and the movable port 27 work together to stop the lifting mechanism when the lifting mechanism controls the stirring assembly to move downwards, and the operator observes that the connection cover 26 is engaged with the movable port 27. This limits the position of the stirring shaft 25, preventing it from colliding with the bottom of the reaction flask 12 and damaging it. Simultaneously, the rotatable connection between the connection cover 26 and the stirring shaft 25 ensures that the connection cover 26 remains stationary while the stirring shaft 25 rotates.

[0031] Specifically, by fastening the connecting cap 26 to the movable opening 27, splashing of the solution inside the reaction flask 12 can be prevented during the reaction.

[0032] Specifically, the diameter of the movable opening 27 is larger than the diameter of the stirring shaft 25 to avoid interference between the stirring shaft 25 and the movable opening 27 when the stirring shaft 25 moves up and down.

[0033] In an embodiment of this utility model, the output end of the injection pump 16 is connected to one end of the drip tube 29 via a quick connector 28, and the other end of the drip tube 29 passes through the mounting cap 13 and is embedded in the reaction flask 12.

[0034] The output end of the syringe pump 16 is connected to the drip tube 29 via the quick connector 28, so as to quickly disassemble or install the drip tube 29, thereby facilitating the replacement of the drip tube 29.

[0035] In an embodiment of this utility model, it further includes: an annular groove 30 and a plug 31; the annular groove 30 is disposed on the top of the reaction flask 12, the plug 31 is connected to the bottom of the mounting cap 13, and the plug 31 is embedded in the annular groove 30.

[0036] The use of the annular groove 30 and the insert block 31 facilitates quick positioning of the mounting cover 13, ensuring that the mounting block is positioned at the opening of the reaction bottle 12, and that the reserved opening and movable port 27 on the mounting cover 13 correspond to the drip tube 29, the detection end of the glass electrode 17, and the connecting cover 26, respectively.

[0037] In an embodiment of this utility model, the exhaust system includes: a centrifugal fan 32, a spray tank 33, and a gas monitoring sensor 34; the top of the housing 10 is provided with a centrifugal fan 32, the exhaust end of the centrifugal fan 32 is connected to the housing 10, and the exhaust end of the centrifugal fan 32 is connected to the spray tank 33; the housing 10 is provided with a gas monitoring sensor 34.

[0038] The gas inside the chamber 10 is monitored by the gas monitoring sensor 34. When harmful gas is detected inside the chamber 10, the centrifugal fan 32 is started to extract the harmful gas from the chamber 10 and inject it into the spray water tank 33 for wet treatment. This reduces the discharge of harmful gas and avoids the situation where the accumulation of harmful gas interferes with the pH value measurement and thus affects the determination of the titration endpoint.

[0039] In an embodiment of this utility model, the connecting seat 14 is provided with a clamping frame 35, which is an elastic body, and the mounting cover 13 is provided with a mounting sleeve 36. The clamping frame 35 fixes the top of the glass electrode 17, and the bottom of the glass electrode 17 passes through the mounting sleeve 36.

[0040] The glass electrode 17 is fixed in position by the clamping bracket 35, and when the lifting mechanism drives the connecting seat 14 to move downward, the bottom of the glass electrode 17 passes through the mounting sleeve 36, thereby protecting the glass electrode 17 and preventing damage to the glass electrode 17.

[0041] In an embodiment of this utility model, the mounting cover 13 is provided with an exhaust port 37.

[0042] By setting an exhaust port 37 on the mounting cover 13, harmful gases in the reaction bottle 12 are discharged into the chamber 10 through the exhaust port 37 and discharged by the centrifugal fan 32, thus avoiding the accumulation of harmful gases and interference with pH measurement.

[0043] Implementation process: The operator opens the door of the chamber 10, places the reaction flask 12 containing the pretreated magnesium ore sample into the placement slot 19 of the heating base 11, covers the top opening of the reaction flask 12 with the mounting cap 13, and inserts the temperature sensor 18; the lifting mechanism drives the connecting base 14 and the stirring assembly and glass electrode 17 fixed on the connecting base 14 to move downwards, so that the working end of the stirring assembly, the sensing end of the glass electrode 17 and the drip tube 29 pass through the mounting cap 13 and are inserted into the reaction flask 12, and then the lifting operation stops; after closing the chamber door and setting the reaction temperature, titration rate and pH endpoint value for this titration analysis, the syringe pump 16, the heating base 11 and the stirring assembly are started to operate, thereby uniformly heating the reaction flask 12 and stirring the solution in the reaction flask 12 at a uniform speed, so that it is heated evenly and reacts fully, and during the titration, the glass electrode 17 continuously monitors the pH value of the solution in the reaction flask 12. When the pH value is detected to reach the titration endpoint, the syringe pump 16 stops working, reducing the error of human titration. Furthermore, harmful gases generated during the reaction are discharged through the exhaust system, thereby preventing the accumulation of harmful gases from interfering with the pH measurement and thus affecting the determination of the titration endpoint.
