[0020] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0021] This utility model discloses a water quality standard solution titration device, which includes a first container 1, a liquid passage pipe, a solution container, a water pump, a control valve, a flow meter, and a colorimetric detection component 14. The first container 1 is used to hold at least a mixed liquid. At least two liquid passage pipes are provided, which are used to supply liquid flow. One end of each liquid passage pipe is connected to a burette, which extends above the first container 1 so that the liquid in the burette drips into the first container 1. The number of liquid passage pipes and the number of burettes are set according to the type of liquid to be mixed. In this embodiment, there are two liquid passage pipes and two burettes, namely a first liquid passage pipe 2 and a second liquid passage pipe 3, a first burette 15 and a second burette 16.

[0022] Each of the liquid-passing pipes has its end furthest from the burette connected to a solution container, so that liquid in the solution container flows into the liquid-passing pipe. The solution container is used to hold the solution to be mixed.

[0023] The water pump is connected to the liquid flow pipe. Driven by the water pump, the liquid in the solution container drips into the first container 1 through the liquid flow pipe and the burette. The control valve and the flow meter 17 are both installed on the burette. The control valve is used to control the opening and closing of the burette, and the flow meter 17 is used to measure the flow rate through the burette.

[0024] The colorimetric detection component 14 is disposed above the first container 1. The colorimetric detection component 14 is used at least to detect the color of the liquid in the first container 1 and compare it with the color of a standard liquid. The colorimetric detection component 14 may include a colorimeter, a color difference meter, or a YH1600 color haze meter. In this embodiment, the colorimetric detection component 14 includes a YH1600 color haze meter. Before use, the color of the standard liquid is set on the control mechanism.

[0025] The water pump drives the solution through the liquid passage and burette into the first container 1, replacing manual dripping and thus automating the process. This reduces experimental errors caused by repeated manual color comparisons, simplifies the operation, and lowers labor costs. Simultaneously, the colorimetric detection component 14 in this application monitors the color of the mixed liquid and compares it with the color of a standard liquid, replacing manual comparison, reducing errors, and improving color comparison accuracy.

[0026] In some implementations, to ensure uniform mixing of the liquid, a stirring assembly is installed within the first container 1. This stirring assembly is used at least to stir the mixed solution within the first container 1, thereby achieving uniform mixing. Specifically, the stirring assembly includes a stirring magnet 10, a permanent magnet, and a drive circuit. The drive circuit is used at least to energize the permanent magnet, which in turn drives the stirring magnet 10 to move, thus stirring the mixed liquid within the first container 1. The permanent magnet drives the stirring magnet 10 using magnetic circuit driving technology. This magnetic circuit driving technology employs high-performance rare-earth permanent magnets and is controlled by an intelligent frequency conversion drive circuit. This technology utilizes permanent magnets to construct a magnetic circuit, and the intelligent frequency conversion drive circuit precisely adjusts the current magnitude and frequency, allowing the magnetic fields to cooperate and work synergistically. This application uses an energized permanent magnet to drive the stirring magnet 10 to rotate, thereby stirring the mixed liquid, saving manpower and achieving automatic stirring.

[0027] In some implementations, a flow control valve 11 is installed on the first liquid passage. The flow control valve 11 is used to control the flow rate of the liquid passing through the first liquid passage. When a certain volume of solution needs to be titrated, the volume of the solution to be titrated is set on the control mechanism. The control mechanism controls the flow control valve 11 to detect the flow rate of the liquid. When the flow control valve 11 detects that the solution flow rate has reached a preset value, it sends a signal to the control mechanism, and the control mechanism controls the flow control valve 11 to close.

[0028] In some implementation cases, such as Figure 2 As shown, the solution container includes a container body 12 and a container cap 13 disposed on the container body 12. For convenient solution replacement, the container body 12 and the container cap 13 are detachably connected. The container body 12 and the container cap 13 can be connected by threads or by snap-fit ​​connections; in this embodiment, the container body 12 and the container cap 13 are connected by threads. The liquid passage is fixedly connected to the container cap 13, and the liquid passage passes through the container cap 13 and extends into the container body 12. When the solution needs to be replaced, the container body 12 is unscrewed from the container cap 13, the liquid passage is cleaned, and a new container body 12 is installed. The detachable connection between the container body 12 and the container cap 13 in this application facilitates the installation and removal of the container body 12, further simplifying solution replacement.

[0029] Example 1:

[0030] like Figure 1As shown, in this embodiment, phenolphthalein indicator needs to be titrated in water (test sample) to determine how much phenolphthalein indicator is needed for a certain volume of water, thereby obtaining the chloride ion content in the water. In this embodiment, two sets of components are provided: a first liquid-passing pipe 2 and a second liquid-passing pipe 3; a first burette 15; a second burette 16; a first solution container 4; a second solution container 5; a first water pump 6; a second water pump 7; a first control valve 8; and a second control valve 9. The first solution container 4 and the first water pump 6 are both located on the first liquid-passing pipe 2. The first control valve 8 is located on the first burette 15. A flow control valve 11 is also provided on the first liquid-passing pipe 2. The flow control valve 11 is connected to a control mechanism, and its threshold is set on the control mechanism. The first solution container 4 contains... Water (test sample) is dripped from the first solution container 4 into the first container 1 through the first liquid passage 2 and the first burette 15 under the drive of the first water pump 6. When a certain volume of water enters the first container 1, the control mechanism controls the flow control valve 11 to close and the first control valve 8 to close. The second solution container 5 and the second water pump 7 are both installed on the second liquid passage 3. The second control valve 9 and the flow meter 17 are installed on the second burette 16. Phenolphthalein indicator is placed in the second solution container 5. Under the drive of the second water pump 7, the phenolphthalein indicator in the second solution container 5 is dripped into the first container through the second liquid passage 3 and the second burette 16.

[0031] A YH1600 color haze meter is installed above the first container 1. A stirring magnet 10 is installed inside the first solution, and a permanent magnet and a drive circuit are installed below the first container 1.

[0032] Working principle:

[0033] First, the preset value of the flow control valve 11 is set on the control mechanism. The water (sample) solution is placed in the first solution container 4, and the phenolphthalein indicator is placed in the second solution container 5. After startup, the first water pump 6 drives the water (sample) through the first liquid passage 2 and the first burette 15 into the first container 1. When the water flow reaches the preset value, a signal is sent to the control mechanism, which then controls the flow control valve 11 and the first control valve 8 to close. At this time, the second water pump 7 drives the phenolphthalein indicator through the second liquid passage 3 and the second burette 16 into the first solution container 5. Inside a container 1; after the permanent magnet is energized, it drives the stirring magnet 10 to rotate, so that the stirring magnet 10 stirs the mixed liquid. The YH1600 color haze meter monitors the color of the mixed liquid in the first container 1 in real time. When the YH1600 color haze meter detects that the color of the liquid in the first container 1 is consistent with the color of the preset standard liquid, it sends a signal to the control mechanism. The control mechanism drives the second water pump 7 to stop working and simultaneously drives the second control valve 9 to close, so that the second burette 16 stops dripping. The flow meter 17 displays the flow rate of the liquid flowing through the burette.
