Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] This application provides a pH precision control device for dye processing, which solves the problem that traditional pH control methods often have some limitations. For example, using conventional acid-base titration methods, it is difficult to achieve precise control of pH value, resulting in unstable dye synthesis reaction and large fluctuations in product quality.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] Example 1:

[0041] This utility model discloses a pH precision control device for dye processing, according to the appendix. Figure 1-7 As shown, it includes a solution storage unit 1, a mixing reaction unit 2, a pH sensor 3, a dosing control unit 4, a control system 5, a protective cover 6, and a locking unit 7.

[0042] Solution storage unit 1 includes several sets of storage tanks for storing solutions of different components, such as acidic solutions and alkaline solutions. These solutions will be used to adjust the pH value during subsequent dye processing. Before dye processing, the required different solutions are injected into their respective storage tanks to ensure that the type and quantity of solution in each storage tank meet the process requirements.

[0043] The mixing reaction unit 2 consists of a mixing container and a stirring structure. The mixing container provides a space for the solution mixing reaction, while the stirring structure, driven by a motor 21, rotates the stirring rod 22 to ensure that the solution in the mixing container is thoroughly and evenly mixed, thus promoting the chemical reaction.

[0044] The stirring structure includes:

[0045] Motor 21 is mounted on the mixing container;

[0046] The stirring rod 22 is located at the output end of the motor 21 and inside the mixing container.

[0047] The mixing container is equipped with a pressure relief valve 23 and a discharge pipe 24.

[0048] The solution in solution storage unit 1 is transported to the mixing container through a pipeline. Motor 21 is started, causing stirring rod 22 to begin stirring, ensuring thorough mixing of the solution. Simultaneously, pressure relief valve 23 installed on the mixing container automatically opens to release pressure if the pressure inside the container becomes too high, ensuring the safe operation of the mixing process. After processing, the solution can be discharged through discharge pipe 24.

[0049] pH sensor 3 is installed on the mixing container and can detect the pH value of the solution in the mixing container in real time. It transmits the detected signal to the control system 5 so that the control system 5 can control the dosing regulation unit 4 according to the change of pH value.

[0050] The pH sensor 3 is mounted on the mixing container and secured by the locking unit 7 to ensure accurate detection of the solution's pH value. During the mixing reaction, the pH sensor 3 continuously operates, transmitting the detected pH data to the control system 5.

[0051] The dosing control unit 4 includes multiple metering pumps, which are respectively installed on the pipelines between several storage tanks and mixing containers. The control system 5 controls the flow rate of each metering pump based on the pH data fed back by the pH sensor 3, thereby precisely adjusting the amount of acidic or alkaline solution added to the mixing container and achieving precise control of the solution pH.

[0052] The control system 5 is connected to the pH sensor 3 and the dosing control unit 4. It receives the pH data from the pH sensor 3 and calculates the amount of acidic or alkaline solution to be added according to the preset pH range through the control algorithm. Then, it controls the feeding speed of each storage tank to achieve precise control of the solution pH.

[0053] During the dye processing, the control system 5 continuously receives data from the pH sensor 3 and adjusts the flow rate of the metering pump in real time based on the data to ensure that the pH value of the solution in the mixing container is always kept within the set range.

[0054] The protective cover 6 is installed on the outside of the pH sensor 3. Its main function is to protect the pH sensor 3 and prevent it from being damaged by impact. It can also reduce the interference of the external environment on the sensor detection results.

[0055] When installing the pH sensor 3, the protective cover 6 is connected to the threaded end 61 on the pH sensor 3 by thread. After installation, it will provide protection.

[0056] The locking unit 7 is disposed on the mixing container and is used to lock and fix the pH sensor 3. The pH sensor 3 is provided with a docking plate 31, and the docking plate 31 is provided with a limiting rod 32. The locking unit 7 includes:

[0057] The guide rail 71 is rotatably connected to the mixing container;

[0058] Slider 72 is slidably connected to guide rail 71;

[0059] The pressure block 73 is fixedly connected to the slider 72 and snapped into the mating plate 31 and the limiting rod 32;

[0060] The lead screw 74 is rotatably connected to the guide rail frame 71 and threadedly connected to the slider 72.

[0061] The locking unit 7 is rotatably connected to the mixing container via the guide rail frame 71. The slider 72 slides on the guide rail frame 71. The pressure block 73 is fixedly connected to the slider 72 and engages with the docking plate 31 and the limiting rod 32 on the pH sensor 3. The lead screw 74 is rotatably connected to the guide rail frame 71 and threadedly connected to the slider 72. By rotating the lead screw 74, the slider 72 can be moved, thereby locking or releasing the pressure block 73 on the pH sensor 3.

[0062] When installing pH sensor 3, place it in the mixing container mounting position, rotate the guide rail 71 and turn the lead screw 74 to move the slider 72, causing the pressure block 73 to engage with the docking plate 31 and the limiting rod 32, thus locking the pH sensor 3. To remove pH sensor 3, reverse the rotation of the lead screw 74 and guide rail 71 to move the slider 72, causing the pressure block 73 to release the docking plate 31 and the limiting rod 32, allowing the pH sensor 3 to be removed. This facilitates the maintenance or replacement of pH sensor 3.

Figure 1-7 As shown, it includes a solution storage unit 1, a mixing reaction unit 2, a pH sensor 3, a dosing control unit 4, a control system 5, a protective cover 6, and a locking unit 7.

[0065] Solution storage unit 1 includes several sets of liquid storage tanks;

[0066] Mixing reaction unit 2 includes a mixing container and a stirring structure;

[0067] pH sensor 3 is installed on the mixing container;

[0068] The dosing control unit 4 includes multiple metering pumps, which are respectively installed on the pipeline between several storage tanks and mixing containers.

[0069] The control system 5 is connected to the pH sensor 3 and the dosing control unit 4 and is used to control the feeding speed of each storage tank;

[0070] Six protective covers are installed on the outside of pH sensor 3;

[0071] The locking unit 7 is disposed on the mixing container and is used to lock the pH sensor 3.

[0072] The mixing container is equipped with a rotating shaft 711, and a sleeve 712 is fixedly connected to the guide rail frame 71 and sleeved on the rotating shaft 711. The guide rail frame 71 and the mixing container are rotatably connected through the design of the rotating shaft 711 and sleeve 712 to ensure stable connection.

[0073] A rubber gasket 33 is movably engaged between the docking plate 31 and the mixing container, which ensures good sealing at the docking point between the docking plate 31 and the mixing container after the pH sensor 3 is installed.

[0074] The pH sensor 3 is provided with a threaded opening 61, and the protective cover 6 is threaded onto the threaded opening 61. The design of the protective cover 6 and the threaded opening 61 makes it easy to disassemble and assemble the protective cover 6, thereby facilitating the regular cleaning and maintenance of the pH sensor 3.
