Description

Technical Field

[0001] This utility model relates to the field of liquid sample classification technology, and in particular to an analytical device that can automatically perform preliminary classification of sampled liquids. Background Technology

[0002] Testing water sources and tap water can promptly detect harmful substances such as bacteria, viruses, heavy metals, and pesticide residues. If these pollutants exceed safe levels, drinking them can lead to various illnesses. For example, heavy metal poisoning can damage the nervous and digestive systems, while microbial contamination can cause intestinal diseases such as diarrhea and dysentery. Wastewater generated from industrial production and scientific research may contain large amounts of heavy metal ions and organic matter. Direct discharge without testing will increase the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) of water bodies, reduce dissolved oxygen, deteriorate water quality, affect the survival of aquatic organisms, and disrupt the aquatic ecological balance.

[0003] Therefore, in production and daily life, it is necessary to test domestic water and discharged wastewater to determine whether they meet safety standards and to safeguard production and daily life.

[0004] Before analyzing liquid samples, they generally need to be classified, such as by acid-base classification. This allows for preliminary screening and grouping of samples, enabling batch processing of samples with similar pH levels using the same or similar analytical methods and conditions, significantly improving testing efficiency. Compared to performing a comprehensive, indiscriminate analysis on every sample, classification before analysis saves considerable time and effort, especially when processing large numbers of samples. Without prior acid-base classification, reagents and consumables unsuitable for the specific pH level may be used indiscriminately, leading to reagent failure or inaccurate results, requiring retesting and wasting reagents and consumables. Acid-base classification allows for targeted selection of appropriate reagents and consumables, avoiding unnecessary consumption and reducing testing costs.

[0005] Currently, the initial classification of liquids largely relies on manual labor. For example, when classifying liquids as acidic or alkaline, staff use pH meters to test multiple independently stored samples one by one. This operation is time-consuming and consumes a significant amount of manpower. In short, manual classification is not only extremely inefficient, but when faced with large-scale sample testing tasks, staff need to spend a great deal of time and energy identifying and classifying each sample individually, severely impacting the overall testing progress.

[0048] Example 1

[0049] To enable acid-base classification of numerous liquid samples before analysis and to batch process samples with similar pH levels using the same or similar analytical methods and conditions, thereby significantly improving detection efficiency, this embodiment provides an analytical device for acid-base classification of liquid samples. This device can automatically detect the pH of multiple liquid samples and place acidic and alkaline liquids in different locations.

[0050] like Figure 1As shown, the analytical device specifically includes a main unit 1, an electrode probe 4, a lifting and moving frame, and a support assembly 3. The lifting and moving frame is installed at the end of the main unit 1, and the electrode probe 4 is mounted on the lifting and moving frame. The electrode probe 4 is connected to the main unit 1 via a cable. Therefore, the movement of the electrode probe 4 can be controlled by the lifting and moving frame to insert or detach it from the liquid sample for acid-base detection. The support assembly 3 is also located at the end of the main unit 1, perpendicular to it. The support assembly 3 can be positioned directly below the electrode probe 4, supporting multiple containers filled with liquid that are sequentially moved below the electrode probe 4 so that the electrode probe 4 can be inserted into the container for batch acid-base detection of the liquid. After the electrode probe 4 completes the acid-base detection of a solution, the container containing that solution can be moved to one edge of the support assembly 3, so that acidic and alkaline solutions are distributed along the two edges of the support assembly 3 for easy access by personnel.

[0051] The electrode probe 4 and main unit 1 mentioned above are existing technologies, forming a pH meter, which will be briefly introduced here. The electrode probe 4 includes a pH glass electrode and a reference electrode. The main unit 1 includes a measurement circuit and a display and control section; the measurement circuit includes a high-impedance amplifier, an A / D converter, and a microprocessor; the display and control section includes a display screen and buttons. Because the internal resistance of the pH glass electrode is very high (typically between tens and hundreds of megohms), a high-impedance amplifier is needed to amplify the weak potential signal generated by the electrode. The A / D converter converts the amplified analog potential signal into a digital signal, and the microprocessor calculates and processes the converted digital signal, converting the potential value into the corresponding pH value according to a pre-set calibration curve or algorithm. Additionally, a pH meter equipped with RS232, USB, or other interfaces and a printer can be connected via a dedicated data cable to print the data acquired by the main unit 1 into labels, providing convenience for staff to apply them to various containers.

[0052] like Figure 1 , Figure 2 , Figure 3 As shown, in order to control the movement of the electrode probe 4, the lifting and moving frame includes a support frame 2, a horizontal plate 41, an electric cylinder 11, a second motor, etc.

[0053] like Figure 2 , Figure 3As shown, a support sleeve 23 is bolted to the bottom of the support frame 2 and connected to the main unit 1. Therefore, the support sleeve 23 controls the support frame 2 to be stably installed at the end of the main unit 1. Additionally, a fixing sleeve 22 is bolted to the support frame 2, and an electric cylinder 11 is mounted on the side of the fixing sleeve 22. The fixing sleeve 22 ensures the electric cylinder 11 is stably installed on the side of the support frame 2. Furthermore, multiple through holes 24 are provided on the support frame 2, distributed along the height direction of the support frame 2. Therefore, the position of the fixing sleeve 22 can be adjusted by removing the bolts as needed, facilitating the installation of the electric cylinder 11 in the appropriate position.

[0054] like Figure 3 As shown, a lifting sleeve 21 is also provided on the support frame 2. The lifting sleeve 21 includes two tubes that are perpendicularly connected to each other. One tube is sleeved on the support frame 2 and is connected to the telescopic end of the electric cylinder 11. Therefore, the lifting sleeve 21 can be controlled to move up and down under the action of the electric cylinder 11. The other tube is sleeved on the horizontal plate 41.

[0055] like Figure 4 , Figure 5 As shown, in order to control the movement of the horizontal plate 41 relative to the support frame 2, a notch is provided on the side wall of the lifting sleeve 21, and a bracket 25 is fixedly installed on the side of the lifting sleeve 21. The second motor is installed at the bracket 25, and a drive gear 43 is provided on the power output shaft of the second motor, which passes through the notch. A rack 42 is provided on the horizontal plate 41, and the rack 42 is arranged along the length direction of the horizontal plate 41. Therefore, the drive gear 43 meshes with the rack 42, so that the movement of the horizontal plate 41 relative to the lifting sleeve 21 can be controlled when the second motor is working, and the movement of the horizontal plate 41 in vertical space can be achieved by cooperating with the lifting and lowering of the lifting sleeve 21.

[0056] like Figure 2As shown, in order to control the operation of the lifting and moving frame and to work in coordination with the host 1, an electrical control box 12 is provided on the side of the support sleeve 23. The electrical control box 12 is connected to the motor (in this embodiment, the motor can be a servo motor, stepper motor, etc.) to control the operation of the motor. The electrical control box 12 is existing publicly available technology, and it includes at least a circuit breaker, contactor, relay, push-button switch, controller (such as PLC), frequency converter, switching power supply, etc. The connection method between the motor and the electrical control box 12 has been disclosed and will not be described in detail here. The pH meter and the electrical control box 12 can realize signal transmission. The transmission method can be wired, such as through shielded cable connection to reduce interference and ensure stable signal transmission; or it can be wireless, using Bluetooth, Wi-Fi or other wireless communication technologies to increase the flexibility of equipment layout. After receiving the signal from the pH meter, the controller in the electrical control box will process it according to the preset program and logic. According to the instructions issued by the controller, the electrical control box can control the operating status of external equipment to realize the control of related operations.

[0057] like Figure 1 , Figure 2 As shown, in order to adjust the position of the electrode probe 4 by means of the lifting and moving frame, the electrode probe 4 is installed at the end of the horizontal plate 41. Therefore, the acid-base detection of liquid samples can be completed by means of the operation of the lifting and moving frame.

[0058] like Figure 7-10 As shown, in order to support multiple containers containing liquid samples and move them sequentially below the electrode probe 4, the support assembly 3 includes an upper plate 31, a lower plate 32, and multiple support wheels 33. The upper plate 31 and the lower plate 32 are arranged vertically opposite each other. The lower plate 32 is placed on the worktable, and the upper plate 31 directly supports multiple containers. The multiple containers are distributed along the length of the upper plate 31 and are located in the middle of the upper plate 31. In addition, multiple points can be drawn on the upper plate 31 to achieve fixed-point placement of the containers. Multiple support wheels 33 are evenly distributed on both edges of the space formed by the upper plate 31 and the lower plate 32, and the support wheels 33 are meshed with the upper plate 31. At the same time, the support wheels 33 are mounted on the lower plate 32. In addition, a first motor 332 is provided at the end of the lower plate 32. The first motor 332 is connected to the support wheels 33 through a chain. Therefore, under the action of the first motor 332, the rotation of multiple support wheels 33 can be controlled, forcing the upper plate 31 to move along the length direction of the lower plate 32, changing the position of multiple containers, and thus causing multiple containers containing liquid samples to move sequentially to below the electrode probe 4.

[0059] like Figure 10As shown, in order to stably mount the support wheel 33 on the lower plate 32, a vertical plate 331 is sleeved on the central shaft of the support wheel 33 via a bearing connection, and the vertical plate 331 is stably mounted on the lower plate 32. In order to control the rotation of multiple support wheels 33, a sprocket is provided at the end of the central shaft of the support wheel 33. The sprockets of the support wheels 33 located on the same edge are connected by a chain. Therefore, the rotation of multiple support wheels 33 can be controlled under the action of the first motor 332.

[0060] like Figure 9 , Figure 10 As shown, in order to drive the upper plate 31 to move under the action of the support wheel 33, multiple grooves are provided on the side wall of the support wheel 33. The multiple grooves are evenly distributed along the circumference of the support wheel 33. Multiple protrusions 311 are provided on both edges of the lower side of the upper plate 31. The multiple protrusions 311 are evenly distributed along the length of the upper plate 31, and the protrusions 311 are engaged with the grooves.

[0061] like Figure 8 , Figure 9 As shown, in order to make the upper plate 31 and the lower plate 32 stably and movably connected, a guide rail 321 is fixedly installed above the lower plate 32. The guide rail 321 is arranged along the length direction of the lower plate 32. A sleeved arc plate 312 is fixedly installed below the upper plate 31. The sleeved arc plate 312 is sleeved on the guide rail 321. Therefore, with the cooperation of the sleeved arc plate 312 and the guide rail 321, the position of the upper plate 31 relative to the lower plate 32 can be restricted without affecting the movement of the upper plate 31, which provides convenience for controlling the movement of the container containing liquid.

[0062] like Figure 7 , Figure 8 , Figure 11 As shown, in order to clean the electrode probe 4 and reduce the risk of cross-contamination, a bracket 322 is fixedly installed on the side of the lower plate 32. The bracket 322 and the horizontal plate 41 are on the same straight line, and a cleaning cup 34 is installed on the bracket 322. The top and bottom of the cleaning cup 34 are connected by a tube. One end of the tube is connected to a liquid pump or faucet through a pipe, and the other end of the tube is connected to a sewer through a pipe, so that cleaning liquid can be continuously injected into the cleaning cup 34 to clean the electrode probe 4, which facilitates the acid and alkali detection of the liquid in the next container.

[0063] Example 2

[0064] like Figure 6As shown, based on Example 1, in order to distribute acidic and alkaline liquids on both edges of the upper plate 31, two sets of arc-shaped abutments 44 are symmetrically arranged on the outside of the electrode probe 4. The two sets of arc-shaped abutments 44 are connected by bolts and form a frustum shell structure with a smaller top and a larger bottom. At the same time, the top of the arc-shaped abutments 44 contacts the electrode probe 4. In addition, the bottom of the two sets of arc-shaped abutments 44 can be fitted onto the top of the container and can drive the container to the edge of the upper plate 31 when the horizontal plate 41 controls the movement of the electrode probe 4, thereby realizing the distribution of multiple containers.
