Description

Technical Field

[0001] This utility model relates to the field of chemical titration apparatus, and in particular to a rapid chemical titration analysis apparatus. Background Technology

[0002] Accurately determining the heavy metal content in soil is a crucial step in assessing the degree of soil pollution and developing scientific remediation plans. Chemical titration analysis, as a classic and widely used quantitative analytical method, plays a vital role in the detection of heavy metal soil pollution. Through chemical titration, the concentrations of various heavy metal ions in soil samples can be precisely determined, providing crucial data support for soil pollution remediation and environmental protection, and is of great significance for maintaining ecological balance and ensuring sustainable agricultural development.

[0003] Currently, traditional chemical titration devices used in heavy metal soil pollution detection have a series of problems. Regarding titration accuracy, due to the complex environment of soil sample testing, limited laboratory space, and frequent personnel and equipment movement, traditional devices lack effective container fixation structures. During titration, the container is highly susceptible to vibration interference, such as vibrations from normal instrument operation and ground vibrations caused by personnel movement. These vibrations can cause deviations in the position of the titrant entering the container, thus affecting the accurate determination of the titration endpoint. For example, when testing for heavy metals such as lead and cadmium in soil samples, even a small error in determining the titration endpoint can lead to a misjudgment of the degree of soil pollution, resulting in a lack of targeted subsequent remediation measures. Regarding titration efficiency, traditional devices have cumbersome operating procedures. Testing personnel need to manually squeeze the dropper or operate complex separatory funnels to control the flow rate and volume of the titrant, which is not only inconvenient to operate but also makes rapid titration difficult. When faced with a large number of soil sample testing tasks, the low efficiency of manual operation will seriously delay the testing progress, failing to provide timely data support for soil pollution remediation and affecting the timeliness of remediation work. From a durability perspective, most chemical reagents used for heavy metal soil pollution detection are corrosive. Components in traditional titration apparatus that come into contact with these reagents, such as metal pistons and valves, are highly susceptible to corrosion during long-term use. Once these components rust or wear, the apparatus's sealing performance deteriorates, leading to reagent leakage, further reduction in titration accuracy, and even rendering the apparatus unusable. This not only increases maintenance costs and replacement frequency but can also cause data interruption and inaccuracies. Therefore, the development of a high-precision, high-efficiency, and durable rapid chemical titration analysis device for heavy metal soil pollution detection is urgently needed. Utility Model Content

[0004] To address the problems of poor titration accuracy, low efficiency, and insufficient durability of existing technologies in the detection of heavy metal soil pollution, this application provides a rapid chemical titration analysis device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rapid chemical titration analysis device includes a base, an internal motor slot housing a motor, a transmission slot on the top side of the motor slot, a turntable fixedly connected to the drive end of the motor, arc-shaped grooves on both the left and right sides of the turntable, and fixing components disposed within the arc-shaped grooves. A liquid storage tank is fixedly connected to the rear side of the base, and a control component is disposed within the liquid storage tank. Through slots are provided on both the left and right sides of the top side of the transmission slot.

[0007] As a further improvement of this utility model, the fixing component includes a slide rod, a slider is fixedly connected to the top side of the slide rod, a fixing member is fixedly connected to the top side of the slider, and a limiting piece is fixedly connected to the bottom side of the slide rod.

[0008] As a further improvement of this utility model, the sliding rod is located inside the arc-shaped groove, and the slider is located inside the through groove.

[0009] As a further improvement of this utility model, the control component includes a screw, the left side of which is rotatably connected to the left side of the inner wall of the liquid storage tank, and a sealing block is sleeved on the outer wall of the screw.

[0010] As a further improvement of this utility model, the left side of the sealing block is connected to the right side of the inner wall of the liquid storage tank through a telescopic protective sleeve, and the left end of the screw passes through the left side of the outer wall of the liquid storage tank and is fixedly connected to a knob.

[0011] As a further improvement of this utility model, an inlet hole is provided at the left end of the top side of the liquid storage tank, and a bucket lid is threadedly connected to the inside of the inlet hole.

[0012] As a further improvement of this utility model, a connecting arm is fixedly connected to the left end of the top side of the base, and a drip tube is fixedly connected to the top end of the connecting arm.

[0013] As a further improvement of this utility model, the top side of the drip tube is connected to the right end of the top side of the storage tank via an infusion hose.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this invention, a motor-driven turntable moves a sliding rod and slider to automatically fix the container, preventing it from shaking during titration and ensuring titration accuracy. Rotating the knob drives a screw to compress the liquid in the storage tank, enabling rapid titration, improving experimental efficiency, and meeting the high efficiency and stability requirements of titration operations in chemical analysis, thus providing strong support for accurately obtaining experimental data.

[0016] 2. In this invention, the telescopic protective sleeve installed on the outer wall of the screw effectively prevents corrosion of the screw by chemical liquids. During frequent titration operations, the corrosive nature of the chemical liquids can easily damage the screw. The protective sleeve reduces the degree of corrosion, extends the service life of the screw and the entire device, and lowers equipment maintenance and replacement costs. Simultaneously, the design of rotating the knob to drive the screw and push the sealing block to squeeze the liquid allows for rapid dripping of the chemical liquid into the container, significantly shortening the titration time, further improving experimental efficiency, and ensuring the long-term stable operation of the analytical device while increasing work efficiency.

[0029] Example 1:

[0030] Reference Figures 1-4An embodiment of this utility model provides a rapid chemical titration analysis device, comprising a base 1, a motor slot inside the base 1, a motor 14 installed inside the motor slot, a transmission slot on the top side of the motor slot, a turntable 12 fixedly connected to the drive end of the motor 14, an arc-shaped groove 11 on both the left and right ends of the turntable 12, a slide rod 10 disposed inside the arc-shaped groove 11, a liquid storage tank 6 fixedly connected to the rear side of the base 1, a screw 17 disposed inside the liquid storage tank 6, through grooves 7 on both the left and right ends of the top side of the transmission slot, a slider 9 fixedly connected to the top side of the slide rod 10, a fixing member 8 fixedly connected to the top side of the slider 9, a limiting piece 13 fixedly connected to the bottom side of the slide rod 10, the slide rod 10 located inside the arc-shaped groove 11, the slider 9 located inside the through groove 7, a connecting arm 3 fixedly connected to the left end of the top side of the base 1, a drip tube 4 fixedly connected to the top end of the connecting arm 3, and the top side of the drip tube 4 connected to the right end of the top side of the liquid storage tank 6 through an infusion hose 5.

[0031] Specifically, when operating this rapid chemical titration analysis device, the first step is to open the lid 2, pour the required chemical liquid into the storage tank 6, and then close the lid 2 again. Next, place the container for receiving the titration liquid on the top surface of the base 1. After the preparation is complete, start the motor 14. The motor 14 will drive the turntable 12 to rotate, and the rotation of the turntable 12 will cause the two connected sliders 10 to slide within the arc-shaped groove 11. Since the slider 9 is located in the through groove 7, as the turntable 12 rotates, the two fixing parts 8 connected to the slider 9 will gradually move towards the center, eventually firmly fixing the container placed on the top side of the base 1. This effectively prevents the container from shaking during the titration process and ensures the accuracy of the titration.

[0032] Example 2:

[0033] Reference Figures 1-4 The left side of the screw 17 is rotatably connected to the left side of the inner wall of the liquid storage tank 6. A sealing block 16 is fitted on the outer wall of the screw 17. The left side of the sealing block 16 is connected to the right side of the inner wall of the liquid storage tank 6 through the telescopic protective sleeve 15. The left end of the screw 17 passes through the left side of the outer wall of the liquid storage tank 6 and is fixedly connected to a knob 18. An inlet hole is opened at the left end of the top side of the liquid storage tank 6. A bucket cover 2 is threadedly connected inside the inlet hole.

[0034] Specifically, after the container is fixed, turn knob 18. Turning knob 18 causes screw 17 to rotate synchronously, pushing sealing block 16 within the storage tank 6. The movement of sealing block 16 compresses the chemical liquid within the storage tank 6, causing it to flow under pressure through infusion tubing 5 into drip tube 4, and then precisely into the container below. This achieves rapid titration and analysis of the chemical liquid. Notably, the device is designed with durability in mind. A telescopic protective sleeve 15 is fitted over the outer wall of screw 17, effectively preventing prolonged contact between screw 17 and the chemical liquid, avoiding corrosion, extending its service life, and ensuring the stable operation of the entire rapid chemical titration analysis device.

[0035] Working principle: In use, first open the lid 2 and put the required chemical liquid into the storage tank 6, then close the lid 2 again. Then place the container on the top side of the base 1, and start the motor 14 to drive the turntable 12 to move, thereby driving the two sliding rods 10 to slide inside the arc groove 11. Since the slider 9 is located inside the through groove 7, when the turntable 12 rotates, the two fixing parts 8 will move towards the middle, thereby fixing the container placed on the top side of the base 1 and preventing the container from shaking during the titration process. Then turn the knob 18 to drive the screw 17 to rotate, thereby driving the sealing block 16 to move and squeezing the chemical liquid inside the storage tank 6, so that the liquid inside flows into the drip tube 4 through the infusion hose 5. The sealing block 16 will not move due to the high internal hydraulic pressure, and the liquid will fall into the container through the drip tube 4, thus enabling rapid titration and analysis of the chemical liquid. At the same time, the outer wall of the screw 17 is provided with a telescopic protective sleeve 15, which can prevent the screw 17 from being corroded due to long-term exposure to chemical liquid.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
