Description

Technical Field

[0001] This utility model belongs to the field of experimental analysis equipment, and specifically relates to a solid sample liquefaction and quantitative separation device. Background Technology

[0002] In numerous fields such as scientific research, medicine, and chemical engineering, the processing and analysis of solid samples is a fundamental task, and its accuracy directly affects the validity and reliability of research results. This is especially true in chemical and biological experiments, where the handling of solid samples is crucial because many reactions and analyses in these fields require a liquid environment. Therefore, converting solid samples to a liquid state and ensuring the integrity and purity of the sample during this process is essential for experimental success.

[0003] The limitations of traditional solid sample processing methods include:

[0004] Temperature sensitivity: Many compounds undergo structural changes or decomposition at high temperatures, leading to alterations in sample properties. Traditional liquefaction methods typically employ high-temperature heating, which may not only damage the original properties of the sample but also cause some components to volatilize, resulting in sample loss.

[0005] Low processing efficiency: Using traditional methods (such as grinding and heating) to convert solids into liquids often takes a long time, and the process requires constant monitoring to avoid overheating or other adverse effects, which reduces the overall work efficiency.

[0006] Sample contamination risk: During heating or mechanical pulverization, the sample may come into contact with container materials or other impurities, introducing contamination. Even trace amounts of contaminants can significantly affect experimental results, especially in high-sensitivity detection.

[0007] Accuracy of quantitative sample division: After liquefaction, the sample needs to be precisely divided into multiple small portions for use in different experiments. However, traditional sample division tools and techniques are difficult to achieve extremely high accuracy, especially when processing trace samples. Uneven sample division can directly affect the reliability and repeatability of experimental data.

[0008] Operational complexity: Traditional sample processing procedures typically involve multiple steps, from sample collection, pretreatment, liquefaction to final dispensing, each of which can increase the probability of error. Furthermore, the complex procedures also increase the need for and cost of personnel training.

[0009] Based on this, the present invention proposes a solid sample liquefaction and quantitative separation device. Utility Model Content

[0021] The first valve, the second valve, and the third valve are each connected to a valve control switch; the valve control switch is used to control the amount of liquid flowing through the first valve, the second valve, and the third valve.

[0022] In some preferred embodiments, a plurality of the valve control switches are connected to a first controller; the first controller is used to control the opening and closing states and opening and closing times of the valve control switches, thereby controlling the amount of liquid flowing through the first valve, the second valve and the third valve.

[0024] In some preferred embodiments, the human-machine interface module is also connected to a second controller, which is connected to the liquefier and is used to control the liquefaction parameters of the liquefier.

[0025] In some preferred embodiments, one valve control switch is connected to a fourth valve, one end of which is connected to one end of a third valve, and the other end of which is connected to a vacuum pump, which provides a negative pressure environment for the target solid container to reduce the flow resistance of the liquid.

[0026] The beneficial effects of this utility model are:

[0027] Improved sample processing efficiency: By integrating multi-functional modules such as liquefaction, quantification, sample separation and control, a continuous automated process of sample processing from solid to liquid and then to precise distribution is realized, which greatly improves the efficiency of sample processing.

[0038] like Figure 1 As shown, this utility model provides a solid sample liquefaction and quantitative separation device, including a liquefaction module 1, a quantitative module 2, a sample separation module 3, and a control module 4;

[0039] The liquefaction module 1 is used to store solid samples and perform liquefaction processing. The outlet of the liquefaction module 1 is connected to the inlet of the quantitative module 2. The quantitative module 2 is used to quantitatively sample the liquefied solid sample. The outlet of the quantitative module 2 is connected to the inlet of the sampling module 3. The sampling module 3 is used to separate the quantitatively sampled liquid.

[0040] The control module 4 is connected to and controls the liquefaction module 1, the quantitative module 2 and the sample dispensing module 3 respectively.

[0041] The steps in using this utility model are as follows:

[0042] Step S1: Place the solid sample to be processed into the container of liquefaction module 1 and close the sealing cap.

[0043] Step S2: Set the appropriate heating temperature and stirring speed through the control module 4 to start the liquefaction process.

[0044] Step S3: After the sample is completely liquefied, open the valve between the liquefaction module 1 and the quantitative module 2 to allow the liquefied sample to flow into the quantitative module 2.

[0045] Step S4: Set the required number of samples on the control module 4 and start the quantitative module 2 to begin sampling.

[0046] Step S5: After sampling is completed, start the sampling module 3 to evenly distribute the sample into the target container.

[0047] After all operations are completed, turn off all devices, clean up any residue, and prepare for the next use.

[0048] The liquefaction module 1 in this invention can consist of a sealed container, inside which a heating element (such as a heating wire or resistance wire) and a stirrer (such as an electric stirring rod) are installed. A temperature controller can be installed on the outside of the container to ensure that the sample is liquefied at a suitable temperature.

[0049] In this embodiment, the liquefaction module 1 includes a solid container 11, a liquefier 12, and a first valve 13;

[0050] The solid container 11 stores a solid sample. The solid container 11 is disposed inside the liquefier 12. The liquefier 12 is used to liquefy the solid sample in the solid container 11. The outlet of the solid container 11 passes through the liquefier 12 and is connected to one end of the first valve 13. The other end of the first valve 13 is connected to the inlet of the quantitative module 2.

[0051] The liquefier 12 is a microwave heating system or an oscillating homogenizing system.

[0052] The solid container 11 in this invention is made of a material that is resistant to high temperatures and microwaves and has stable chemical properties, such as quartz glass or Teflon, to prevent it from reacting with the sample.

[0053] The solid container 11 can be cylindrical or cuboid, etc., to facilitate the placement and removal of samples and to facilitate cleaning. This utility model does not make specific limitations on its shape.

[0054] The solid container 11 has a sealing cap on top and a small hole at the bottom as an outlet, which is connected to the first valve 13 through a pipe.

[0055] When the liquefier 12 in this utility model is a microwave heating system, the system includes:

[0056] Microwave generator: generates microwave energy to heat solid samples.

[0057] Microwave cavity: contains a solid container 11 to ensure uniform distribution of microwave energy.

[0058] Temperature sensor: Monitors the temperature inside the solid container in real time to ensure the safety and efficiency of the heating process.

[0059] Control unit: Adjusts microwave power and heating time to ensure sample liquefaction under optimal conditions.

[0060] Working principle: The solid container 11 is placed inside the microwave cavity. The microwave generator is activated to generate microwave energy to heat the solid sample. A temperature sensor monitors the temperature in real time and adjusts the microwave power via a control unit to ensure the sample liquefies at the set temperature. Once liquefaction is complete, the microwave generator stops operating.

[0061] When the liquefier 12 in this invention is an oscillating homogenizing system, the system includes:

[0062] Oscillator: Generates mechanical vibrations for breaking and mixing solid samples.

[0063] Oscillation platform: Supports the solid container 11 to ensure that the sample is subjected to uniform force during oscillation.

[0064] Temperature control system: can be selected to control the temperature during the oscillation process to prevent the sample from denaturing due to overheating.

[0065] Control unit: Adjusts the oscillation frequency and time to ensure that the sample is liquefied under optimal conditions.

[0066] Working principle: Place the solid container 11 on the shaking platform. Start the shaker to generate mechanical vibration, which breaks up and mixes the solid sample. The temperature control system monitors and adjusts the temperature to ensure that the sample liquefies at a suitable temperature. After liquefaction is complete, the shaker stops working.

[0067] The first valve 13 in this invention is a corrosion-resistant and high-temperature-resistant solenoid valve or pneumatic valve to ensure stable operation over a long period. It is installed between the outlet of the solid container 11 and the inlet of the quantitative module 2 to control the flow of the liquefied sample. The valve is opened and closed by a signal sent from the control module 4, thereby precisely controlling the timing of sample delivery.

[0068] When a microwave heating system is selected, the overall working process of this embodiment is as follows:

[0069] Add the solid sample to the solid container 11 and close the sealing cap. Ensure the first valve 13 is closed. Place the solid container 11 into the microwave cavity. Set the appropriate microwave power and heating time. Start the microwave generator to heat the sample. The temperature sensor monitors the temperature in real time to ensure safety and efficiency. Once the sample is completely liquefied, the control module 4 sends a signal to open the first valve 13. The liquefied sample flows into the quantitative module 2 through the pipeline. After the sample transfer is complete, close the first valve 13 to prepare for the next operation.

[0070] When an oscillating homogeneous system is selected, the overall working process of this embodiment is as follows:

[0071] Add the solid sample to the solid container 11 and close the sealing cap. Ensure the first valve 13 is closed. Place the solid container 11 on the shaking platform. Set the appropriate shaking frequency and time. Start the shaker to break up and mix the sample. The temperature control system monitors and adjusts the temperature. Once the sample is completely liquefied, the control module 4 sends a signal to open the first valve 13. The liquefied sample flows into the quantitative module 2 through the pipeline. After the sample transfer is complete, close the first valve 13 and prepare for the next operation.

[0072] The quantitative module 2 in this invention can employ a precision pump system (such as a peristaltic pump or syringe pump) equipped with one or more fixed-capacity reservoirs or syringes. The capacity of the reservoir or syringe can be customized according to actual needs to ensure that the same volume of sample is dispensed each time.

[0073] When the liquefied sample flows from liquefaction module 1 into quantitative module 2, a precision pump automatically extracts a predetermined amount of liquid and delivers it to the sample dispensing module. This process can be automatically completed by the control module, ensuring the accuracy and repeatability of each sampling.

[0074] In this embodiment, a structure for the quantitative module 2 is provided, specifically as follows:

[0075] The metering module 2 includes a second valve 21 and a metering tube 22;

[0076] The other end of the first valve 13 is connected to one end of the second valve 21, the other end of the second valve 21 is connected to the inlet of the quantitative tube 22, and the outlet of the quantitative tube 22 is connected to the inlet of the sample dispensing module 3.

[0077] In this embodiment, the quantitative tube 22 is made of a transparent and corrosion-resistant material, such as borosilicate glass or polytetrafluoroethylene (PTFE), to facilitate observation of sample flow. Its shape includes, but is not limited to, cylindrical or cuboid, with a smooth interior for easy sample flow and cleaning.

[0078] The quantitative tube 22 of this invention has graduation lines marked on its outer wall for easy visual estimation of sample volume. A small discharge port can be designed at the bottom of the quantitative tube 22 to empty any remaining sample, ensuring the accuracy of each sampling.

[0079] Connection and operation process:

[0080] Ensure both the first valve 13 and the second valve 21 are closed. Check that the quantitative tube 22 is clean and free of residue. Once the sample in the liquefaction module is completely liquefied, the control module 4 sends a signal to open the first valve 13, allowing the liquefied sample to flow into the second valve 21. Once the sample reaches the second valve 21, the control module 4 sends a signal to open the second valve 21, allowing the sample to enter the quantitative tube 22. When the sample in the quantitative tube 22 reaches the predetermined volume, the control module 4 sends a signal to close the second valve 21, stopping the sample flow. Visually check the scale lines to confirm the accuracy of the sample volume. The control module 4 sends a signal to open the outlet valve of the quantitative tube 22, allowing the sample to flow into the sample dispensing module 3. After sample delivery is complete, close the outlet valve of the quantitative tube 22, preparing for the next sampling.

[0081] In this embodiment, the sample separation module 3 includes a third valve 31 and a target container 32;

[0082] The outlet of the metering tube 22 is connected to one end of the third valve 31, and the other end of the third valve 31 is connected to the inlet of the target solid container 11.

[0083] In this embodiment, when the sample in the quantitative tube 22 reaches the predetermined volume, the control module 4 sends a signal to close the second valve 21.

[0084] Confirm the accuracy of the sample volume by visually inspecting the scale lines.

[0085] The control module 4 sends a signal to open the third valve 31, allowing the sample to flow from the quantitative tube 22 into the target container 32.

[0086] After the sample delivery is complete, close the third valve 31 to prepare for the next sampling.

[0087] As a further explanation of this utility model, the control module 4 includes a plurality of valve control switches 41;

[0088] The first valve 13, the second valve 21 and the third valve 31 are each connected to a valve control switch 41; the valve control switch 41 is used to control the amount of liquid flowing through the first valve 13, the second valve 21 and the third valve 31.

[0089] Each valve control switch 41 can be a relay, a solenoid valve driver, or a stepper motor controller, depending on the type of valve used.

[0090] There are at least three valves, corresponding to the first valve 13, the second valve 21, and the third valve 31 respectively.

[0091] The central processing unit (CPU) of control module 4 sends signals to control the opening and closing of each valve, thereby precisely controlling the flow of the sample.

[0092] As a further explanation of this utility model, the plurality of valve control switches 41 are connected to a first controller 42; the first controller 42 is used to control the opening and closing state and opening and closing time of the valve control switches 41, thereby controlling the amount of liquid flowing through the first valve 13, the second valve 21 and the third valve 31.

[0093] The first controller 42 in this invention can be a microcontroller (such as Arduino or Raspberry Pi) or an industrial-grade PLC (programmable logic controller).

[0094] It can receive user input commands, such as start, stop, and parameter settings. It acquires real-time data through sensors (such as temperature and flow sensors) to ensure the equipment operates within a safe and efficient range.

[0095] It can also send control signals to each valve control switch 41 to control the valve opening and closing time and opening and closing status, as well as display equipment status and alarm information, such as excessive temperature, valve failure, etc.

[0096] As a further explanation of this utility model, the first controller 42 is connected to the human-machine interface module 43, and the human-machine interface module 43 is used to remotely control the first controller 42.

[0097] The human-machine interface module 43 is also connected to the second controller 44, which is connected to the liquefier 12. The second controller 44 is used to control the liquefaction parameters of the liquefier 12.

[0098] In this invention, the human-machine interface module 43 can be a touch screen, a button panel, or remote control software.

[0099] It provides a user-friendly interface, allowing users to easily set parameters and monitor device status. It displays real-time data and historical records for convenient analysis and management. It also offers alarm prompts and fault diagnosis functions to help users promptly identify and resolve problems.

[0100] The human-machine interface module 43 communicates with the first controller 42 and the second controller 44 to achieve remote control.

[0101] The second controller 44 can be a microcontroller (such as Arduino or Raspberry Pi) or an industrial-grade PLC (Programmable Logic Controller). It receives instructions from the human-machine interface module 43. It acquires real-time data from the liquefier 12 through sensors (such as temperature sensors) to ensure the safety and efficiency of the liquefaction process. It sends control signals to the liquefier 12 to control its liquefaction parameters (such as temperature and heating time). It displays the status of the liquefier and alarm information.

[0102] As a further explanation of this utility model, one of the valve control switches 41 is connected to the fourth valve 5, one end of the fourth valve 5 is connected to one end of the third valve 31, and the other end of the fourth valve 5 is connected to the vacuum pump 6. The vacuum pump 6 is used to provide a negative pressure environment for the target solid container 11 to reduce the flow resistance of the liquid.

[0103] In this invention, the fourth valve 5 is installed between one end of the third valve 31 and the vacuum pump 6, and is used to control the establishment and release of the vacuum environment. When a negative pressure environment is required, the fourth valve 5 is opened and the vacuum pump 6 draws a vacuum; when a negative pressure environment is not required, the fourth valve 5 is closed to maintain a normal pressure state.

[0104] The vacuum pump 6 is selected for laboratory use and can provide a stable negative pressure environment. Providing a negative pressure environment for the target container 32 reduces the flow resistance of the liquid and ensures smooth sample delivery.

[0105] The overall usage process of this utility model is as follows:

[0106] Preparation phase:

[0107] Add the solid sample to the solid container 11 and close the sealed lid.

[0108] Ensure that the first valve 13, the second valve 21, the third valve 31, and the fourth valve 5 are all in the closed state.

[0109] Check that the target container 32 is clean and free of residue.

[0110] Liquefaction process:

[0111] The heating temperature and time of the liquefier 12 are set through the human-machine interface module 43.

[0112] The second controller 44 receives the instruction and starts the liquefier 12.

[0113] The temperature sensor monitors the temperature in real time and feeds the data back to the second controller 44.

[0114] When the temperature reaches the set value and is maintained for a certain period of time, the second controller 44 sends a signal to the first controller 42, and the first controller 42 opens the first valve 13.

[0115] Sample transfer:

[0116] The liquefied sample flows into the second valve 21 through the first valve 13.

[0117] The first controller 42 sends a signal to open the second valve 21, allowing the sample to enter the quantitative tube 22.

[0118] Quantitative sampling:

[0119] When the sample in the quantitative tube 22 reaches the predetermined volume, the first controller 42 sends a signal to close the second valve 21.

[0120] Confirm the accuracy of the sample volume by visually inspecting the scale lines.

[0121] Sample delivery:

[0122] The first controller 42 sends a signal to open the third valve 31, allowing the sample to flow from the quantitative tube 22 into the target container 32.

[0123] At the same time, the first controller 42 sends a signal to open the fourth valve 5 and start the vacuum pump 6 to provide a negative pressure environment for the target container 32 and reduce the flow resistance of the liquid.

[0124] After the sample is transported, the first controller 42 sends a signal to close the third valve 31 and the fourth valve 5, and stops the vacuum pump 6, in preparation for the next sampling.
