Description

Technical Field

[0001] This utility model belongs to the field of aluminum foil sheet testing technology, and in particular relates to a reagent mixing device. Background Technology

[0002] When conducting surface grain size testing on sheet materials (such as aluminum foil) in the laboratory, the precise proportion of chemical reagents is crucial. Accurate reagent ratios are the cornerstone of obtaining reliable test results and accurately judging the quality of the sheet materials. However, currently, laboratories mainly rely on manual measurement and mixing of each component in the preparation of these chemical reagents. This traditional method has many drawbacks. On the one hand, the manual operation process is cumbersome, requiring operators to measure different reagents one by one, consuming a significant amount of time and effort, greatly reducing work efficiency. On the other hand, human factors (such as reading errors and differences in operating techniques) can easily lead to deviations in the accuracy of the proportions, thus interfering with the accuracy of the sheet material grain size test results. Most importantly, these types of chemical reagents have highly corrosive and volatile hazardous properties. If reagent spillage occurs during manual operation, it can cause skin burns or poisoning from inhaling toxic fumes, posing a serious threat to the personal safety of operators. The safety hazards are extremely prominent in daily operations.

[0003] The closest existing technology on the market is a semi-automatic reagent mixing device. This device mainly consists of a motor-driven piston pump, electronic sensors, and an operation control panel. The motor-driven piston pump realizes the absorption and delivery of reagents, the electronic sensors monitor the reagent volume in real time, and the operator inputs the required reagent type and volume ratio on the control panel. The device automatically completes the reagent extraction and preliminary mixing operation according to the set program.

[0004] Problems with existing technology:

[0005] High equipment cost: This semi-automatic equipment is expensive to manufacture because it uses precision motors, high-precision electronic sensors and complex control circuits.

[0006] High maintenance difficulty: Most of the chemical reagents used in grain size experiments are highly corrosive, which can damage or degrade the performance of delicate electronic components and complex mechanical parts. Due to the corrosiveness of the reagents and the complexity of the equipment, routine maintenance and upkeep are extremely difficult, and it is hard to monitor internal leaks, posing safety hazards.

[0036] Example

[0037] like Figures 1-9As shown, a reagent mixing device includes a reagent storage tank 5, a mixing and stirring mechanism, a test tank 31, and a waste liquid tank 4. The test tank 31 and the mixing and stirring mechanism are mounted on the waste liquid tank 4. Several reagent storage tanks 5 are connected to the interior of the mixing and stirring mechanism via pipes, and the mixing and stirring mechanism is connected to the test tank 31 via a drain pipe 8. The mixing and stirring mechanism includes a shell 2 and a mixing container 21 disposed inside the shell 2.

The first observation window 22 and the second observation window 23 face each other, and both the first observation window 22 and the second observation window 23 are made of transparent material.

[0038] A leak sensor 71 and a gas concentration sensor 72 are installed inside the housing 2 to monitor whether there is a reagent leak inside the housing 2 and the specific concentration of the leaked reagent.

[0039] The reagent storage box 5 is provided with marking scale 53. The upper side of the reagent storage box 5 is provided with filling port 51. The bottom outlet of the reagent storage box 5 is provided with first valve body 52. ​​First pipe 61 is connected to the first valve body 52. ​​Several first pipes 61 are connected to second pipes 6. A third pipe 62 is provided at the bottom of the second pipe 6. The third pipe 62 is connected to the upper side of the outer shell 2 and communicates with the mixing container 21.

[0040] Furthermore, the outer shell 2 is configured as a frustum structure, and the mixing container 21 is cylindrical.

[0041] The drain pipe 8 passes through the outer shell 2 and connects to the bottom of the mixing container 21. A second valve body 82 is installed on the drain pipe 8. Several test tanks 31 are provided. Several diversion pipes 81 are evenly distributed on the bottom of the drain pipe 8. Each diversion pipe 81 is corresponding to a test tank 31.

By controlling the second valve body 82 and the third valve body 83, the valve body can be opened accordingly to allow the mixed reagent to be introduced into the corresponding test tank 31 for testing.

[0042] Furthermore, several test tanks 31 are integrated on a test tank shell 3. U-shaped snap-fit ​​parts 34 are provided on both sides of the test tank shell 3.

A fourth valve body 33 is set on the waste liquid pipe 32. Using the fourth valve body 33, the reagent waste liquid in the test tank 31 can be discharged into the waste liquid tank 4 for recycling after the test is completed.

[0044] In this invention, the stirring assembly includes a stirring shaft 91 and stirring blades 92 mounted on the stirring shaft 91. A stirring motor 9 is mounted on the bottom side of the outer casing 2. The stirring motor 9 is connected to the stirring shaft 91 for transmission, thereby realizing the reagent mixing and stirring function.

[0045] Furthermore, the leak sensor 71 and the gas concentration sensor 72 are detachably mounted on the detection seat 7, and a slot is cut on one side of the housing 2 for mounting the detection seat 7, which facilitates disassembly and assembly.

[0046] As one preferred method, the leakage sensor 71 uses an electrochemical sensor, such as the Polytron 8100 EC.

[0047] As one preferred method, the gas concentration sensor 72 uses an electrochemical sensor, such as the model: FZ2000-VOC portable VOC gas detector.

[0048] In this utility model, the reagent mixing device also includes a box 1, a waste liquid tank 4, and a mixing and stirring mechanism disposed inside the box 1. An installation box 11 is integrally provided on the upper side of one side of the box 1. A top cover 13 is provided on the upper end of the installation box 11. Several supports 14 are provided inside the installation box 11. The reagent storage box 5 is installed on the supports 14. An operation slot 12 is opened horizontally in the box 1 to facilitate the testing of the test tank 31 and the operation of the mixing and stirring mechanism from the position of the operation slot 12.

[0049] This utility model includes the following components:

[0050] The modular reagent storage container module consists of multiple independent reagent storage boxes 5, each used to store different types of reagents. The reagent storage boxes 5 are made of high-strength, chemically resistant materials, such as special engineering plastics or corrosion-resistant metal alloys. The surface of each reagent storage box 5 is clearly marked with graduations 53 for easy and intuitive reading of reagent levels.

[0051] Precision flow control valve: The first valve body 52 is installed at the outlet of each reagent storage container. The valve uses a high-precision ceramic valve core, which can precisely control the outflow of reagents, with flow adjustment accuracy down to the microliter level. The valve can be opened and closed manually by rotating the knob or remotely controlled by connecting to an automated control system.

[0052] Mixing and stirring unit: Equipped with a mixing container 21 with stirring function, the mixing container 21 is made of a highly corrosion-resistant material such as polytetrafluoroethylene (PTFE) or tantalum. The stirring blades 92 are made of the same corrosion-resistant material as the container. The transmission device between the stirring motor 9 and the mixing container 21 adopts a fully sealed design to prevent reagent splashes from entering the motor, ensuring that different reagents can be mixed quickly and evenly during the mixing process, avoiding uneven mixing.

[0053] Safety Enclosure 2: The entire device is enclosed within a fully sealed safety enclosure 2, which is made of a corrosion-resistant, fire-resistant material with excellent sealing properties. The enclosure 2 is equipped with a first observation window 22, and a second observation window 23, allowing operators to easily observe the measurement and mixing of reagents inside.

[0054] Working Principle: When preparing reagents, the operator first opens the corresponding flow control valve according to the experimental requirements using the manual knob on the first valve body 52. ​​Under the influence of gravity or slight pressure, the reagent flows from the storage container into the mixing container 21 of the mixing unit through the pipeline. During the reagent inflow process, the operator can monitor the outflow of reagents in real time through the scale markings 53 on the container and the auxiliary flow monitoring device installed on the pipeline. After all the reagents have flowed into the mixing container 21 according to the set volume, the stirring motor 9 of the mixing unit is started, and the stirring blades 92 begin to thoroughly stir and mix the reagents, ensuring that a uniform mixture is obtained.

[0055] Throughout the operation, the safety enclosure 2 plays a crucial role. Leakage sensor 71 continuously monitors the device for reagent leaks; upon detection, it shuts off the relevant flow control valves to prevent further leakage. Gas concentration sensor 72 monitors the concentration of harmful gases within enclosure 2 in real time; when the concentration exceeds a safety threshold, it activates the ventilation system to expel the harmful gases, ensuring personnel safety.

[0056] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
