Description

Technical Field

[0001] The invention relates to a Joule heat shock device, in particular to a Joule heat shock automation device and a Joule heat shock method. Background Art

[0002] The high-temperature thermal shock device of the prior art mainly includes four parts, namely a DC power supply, a heating reaction chamber, a spectrometer and a vacuum pump. Specifically, the sample material is connected to the copper sheet through a conductive silver glue and fixed on a glass bracket, and the copper sheets at both ends of the sample are connected to a DC power supply. When the power is turned on, a high-temperature thermal shock will be triggered. The spectrometer is used to record the emission spectrum and estimate the sample temperature. The emission spectrum of the sample is fitted with the blackbody radiation equation, and the instantaneous temperature of the conductive sample during the high-temperature thermal shock process can be analyzed. Its disadvantages are as follows:

[0003] The original method used was to wrap the material with carbon cloth, and then sandwich the cylindrical carbon cloth between two electrodes. This method is cumbersome to operate and the sample preparation is complicated; the sample wrapping is prone to leakage; only one sample can be sintered at a time, and the amount of product obtained from each thermal shock is limited; the vacuum box needs to be opened after the sample is sintered, and the vacuum needs to be re-evacuated after the sample is loaded again. Each vacuuming takes 30-40 minutes, which reduces the experimental efficiency; the vacuum box space of the Joule heat equipment is limited, and fewer components can be placed; the traditional graphite sintering table has uneven heat conduction, which is easy to heat the two ends of the electrode first, and then the temperature is transferred to the middle, which can easily cause the temperature to be too high and burn the electrode, and the heat transfer is uneven. Summary of the invention

[0004] In order to solve the above problems, the present invention realizes automated rapid continuous production by designing a first station, a second station, a third station, a fourth station, a fifth station, a sixth station and a seventh station arranged in sequence, and designs the cross-sectional area of ​​the middle part of the graphite sintering table perpendicular to the length direction of the strip to be smaller than the cross-sectional area of ​​the end part of the container perpendicular to the length direction of the strip, so that the resistance of the middle part is large and the resistance of the end part is small. When the same current is applied, the heating speed of the middle part is faster and the temperature is higher. While ensuring that the temperature of the sample heating is high enough, the temperature of the graphite sintering table on both sides of the electrode is low, and the electrode will not be burned.

[0005] The technical solution of the present invention is as follows: a Joule thermal shock automation device, comprising a first station, a second station, a third station, a fourth station, a fifth station, a sixth station and a seventh station arranged in sequence; The first workstation at least comprises a plurality of sealed first raw material storage containers, a first tray for placing the first raw material storage containers, and a first manipulator for gripping and transferring the first raw material storage containers and the first tray, wherein the raw materials are stored in the first raw material storage containers; A large amount of raw materials are stored in the first station, and the raw materials are placed according to their types to facilitate the first manipulator to pick them up; The second station at least includes a second manipulator for opening different first raw material storage containers, placing samples as needed and transferring them, an electronic scale for weighing raw materials, and a second raw material storage container for storing the weighed raw materials; The number of the first raw material storage containers is determined according to the type of raw materials used, and the electronic scale is used to weigh the raw materials according to the amount required for the reaction; The third station at least includes a third robot for mixing and transferring the raw materials in the second raw material storage container; The third manipulator mixes the raw materials in the second raw material storage container fully and evenly by repeatedly shaking and vibrating, so as to prepare for the subsequent reaction; The fourth station at least includes a fourth manipulator for opening the second raw material storage container and loading the raw material in the second raw material storage container into the graphite sintering table; the main body of the graphite sintering table is a bar with openings at both ends and a hollow interior, and the cross-sectional area of ​​the middle part of the graphite sintering table perpendicular to the length direction of the bar is smaller than the cross-sectional area of ​​the end part of the graphite sintering table perpendicular to the length direction of the bar; The structure of the graphite sintering table makes the resistance in the middle larger and the resistance at the ends smaller. When the same current is applied, the temperature in the middle rises faster and the temperature is higher. While ensuring that the temperature of the sample is heated high enough, the temperature of the graphite sintering table on both sides of the electrode is low, which will not burn the electrode. The fifth station at least includes a fifth manipulator and a sealed box for taking and placing the graphite sintering table; the sealed box has a conveyor belt and a power supply, and the surface of the conveyor belt is provided with a plurality of brackets for supporting the graphite sintering table, and the brackets have depressions adapted to the shape of the graphite sintering table; the sealed box has vacuum or inert gas protection; the positive and negative electrodes of the power supply are used to connect to the two ends of the graphite sintering table, and the thermometer is used to measure the temperature of the middle part of the graphite sintering table after being heated by the power supply; Generally, it is connected by clamping or filled at both ends of the graphite sintering table in the form of a conical plug, or other methods are also possible; The sixth station includes at least a sixth manipulator for taking and placing the graphite sintering table; The seventh station at least comprises a seventh manipulator for taking out the finished product from the graphite sintering table, wherein the seventh manipulator clamps a tool for extending from one end of the graphite sintering table to eject the finished product from the other end of the graphite sintering table; By using tooling, the product after the reaction is poked out from the graphite sintering table for easy collection and standby use.

[0006] Furthermore, the graphite sintering table is cylindrical or rectangular.

[0007] Furthermore, the hollow shape of the graphite sintering table is a spindle shape with a large middle and small ends. The cross-sectional area of ​​the graphite sintering table is small in the middle and large at the ends, so that the resistance of the middle is large and the resistance of the ends is small.

[0008] Furthermore, the hollow shape of the graphite sintering table is a stepped shape with a large middle and small ends. The cross-sectional area of ​​the graphite sintering table is small in the middle and large at the ends, so that the resistance of the middle portion is large.

[0009] Furthermore, the hollow shape of the graphite sintering table is cylindrical, and the outer surfaces of the two ends of the graphite sintering table have raised annular steps. By providing the annular steps, the overall shape of the graphite sintering table is dumbbell-shaped, the cross-sectional area of ​​the middle part of the graphite sintering table is small, and the cross-sectional area of ​​the end part is large, so that the resistance of the middle part is large.

[0010] Furthermore, the cross-sectional shape of the tooling is adapted to the shape of the openings at both ends of the graphite sintering table. Generally, when the shapes of the openings at both ends of the graphite sintering table are circular, the cross-sectional shape of the tooling is also circular, that is, the tooling is in the shape of a round stick. When the shapes of the openings at both ends of the graphite sintering table are rectangular, the cross-sectional shape of the tooling is also rectangular, that is, the tooling is in the shape of a cuboid.

The conveyor belt drives the bracket to the positive and negative connection positions of the power supply. The positive and negative poles of the power supply are respectively connected to the two ends of the graphite sintering table. Then, current is applied to perform Joule thermal shock. Then, the graphite sintering table that has completed the Joule thermal shock is driven by the conveyor belt to the other end of the conveyor belt. (6) The sixth manipulator clamps the graphite sintering table from the bracket and unloads the material; (7) The seventh robot clamps the tooling, extends from one end of the graphite sintering table, and ejects the other end of the finished graphite sintering table.

In this way, while ensuring that the temperature of the sample heating is high enough, the temperature of the graphite sintering table on both sides of the electrode is low, and the electrode will not be burned.

[0016] The embodiments of the present invention are further described below with reference to a plurality of embodiments.

[0017] Example 1 like Figure 1 — Fig.11 A Joule thermal shock method based on the above-mentioned Joule thermal shock automation device comprises the following steps: (1) The first robot grips three required first raw material storage containers (containing petroleum coke, Na2CO3 and NaCl, respectively) and places them on the first tray, and then the first robot grips and transfers the first tray; (2) The second manipulator grabs and places the first tray, then opens the three first raw material storage containers in sequence, takes raw materials from the three first raw material storage containers and places them on an electronic scale for weighing, wherein 0.3 g of petroleum coke, 0.3 g of Na2CO3, and 0.3 g of NaCl are weighed, and after obtaining the required amount, they are stored in the second raw material storage container; then the second raw material storage container is transferred; (3) The third robot grips the second raw material storage container and shakes it to fully mix the raw materials inside; then the second raw material storage container is transferred; (4) The fourth robot grips and opens the second raw material storage container and loads the raw material into the graphite sintering table; then the graphite sintering table is transferred; In this step, the openings at both ends of the graphite sintering table are sealed by fourth manipulators using sealing plugs made of graphite, and the number of fourth manipulators is three.

[0018] The graphite sintering table is cylindrical, and the hollow shape of the graphite sintering table is a spindle shape with a large middle and small ends; (5) The fifth manipulator clamps the graphite sintering table and places it on the bracket at one end of the conveyor belt, closes the box door, evacuates the box, and drives the bracket to the positive and negative connection positions of the power supply through the conveyor belt. The positive and negative poles of the power supply are respectively connected to the two ends of the graphite sintering table. The thermometer is aimed at the middle of the graphite sintering table for continuous temperature measurement, and then current is applied to heat the middle of the sintering table at a rate of 20,000 degrees Celsius per second to 3,000K and the power is immediately cut off, thereby performing Joule thermal shock; then the graphite sintering table that has completed the Joule thermal shock is driven by the conveyor belt to the other end of the conveyor belt; (6) The sixth manipulator clamps the graphite sintering table from the bracket and unloads the material; (7) The seventh manipulator holds the tooling and extends from one end of the graphite sintering table to push out the other end of the finished graphite sintering table. The cross-sectional shape of the tooling is adapted to the shape of the openings at both ends of the graphite sintering table. In this embodiment, Fig. 9 In a, the shapes of the openings at both ends of the graphite sintering table are circular, and the cross-sectional shape of the tooling is also circular, that is, the tooling is in the shape of a round stick.

[0019] In this embodiment, firstly, ultra-high temperature up to 3000 K is used for Joule thermal shock to promote the graphitization process from a thermodynamic point of view; secondly, since the openings at both ends of the graphite sintering table are sealed, the gas inside expands at high temperature, thereby generating a certain pressure, destroying the π-π interaction of the aromatic rings in the carbon molecules, thereby obtaining a mixed structure carbon composed of crystalline and amorphous carbon. The optimized carbon material (DSC-200–0.3) exhibits a capacity of 208.61 mAh / g at a high rate of 10C, which is significantly improved compared to the 15 mAh / g of the original graphite. After 3000 charge and discharge cycles, the material can still maintain 81.06% of the capacity. Dynamic process analysis shows that this excellent rate performance is attributed to the larger interlayer spacing, which is conducive to ion transport, disordered amorphous carbon provides additional lithium storage sites, and crystalline carbon enhances charge transfer. The double-shock chemistry approach provides a cost-effective and efficient route for the rapid production of hybrid structural carbon anodes, enabling lithium-ion batteries to have 10C fast charging capability, opening up a new direction for the development of high-performance energy storage systems.

[0020] The existing equipment on a single test bench can only process 0.5g of sample at a time, but after batch production, it can process kilograms of samples at a time, greatly improving experimental and production efficiency.

[0021] Example 2 In this example, Pt / CNWC was used as the raw material. The synthesis steps were as follows: 200 mg CNW and 4 mL H2PtCl6 (20 mmolL −1 ) solution was added to 20 mL of PVP solution (20 mmol L −1 ) and stirred at room temperature for 10 minutes to make it evenly dispersed. Then the pre-prepared NaBH4 solution (10 mmol L -1 ) was added to the above well-dispersed suspension and stirred for 5 min. Next, the Pt / CNW samples were collected by centrifugation at 10000 rpm, subsequently washed with deionized water, and then dried at 60 °C.

[0022] Deionized water was provided by an ultrapure water system (Milli-Q). Cellulose nanowhiskers (CNW, 5 wt%) were purchased from Northern Century (Jiangsu) Cellulose Materials Co., Ltd. H2PtCl6, NaBH4, and polyvinylpyrrolidone (PVP) were purchased from Sigma-Aldrich. All chemical reagents were used directly without further treatment.

[0023] like Figure 1 — Fig. 9 and Fig.12 — Fig.13A Joule thermal shock method based on the above-mentioned Joule thermal shock automation device comprises the following steps: (1) A first raw material storage container (containing Pt / CNW) is grasped by a first robot and placed on a first tray, and then the first robot grasps and transfers the first tray; (2) The second manipulator grabs and places the first tray, then opens the first raw material storage container, takes the raw material from the first raw material storage container and places it on an electronic scale to weigh 0.5 g Pt / CNW to obtain the required amount and store it in the second raw material storage container; then the second raw material storage container is transferred; (3) The third robot grips the second raw material storage container and shakes it to fully mix the raw materials inside; then the second raw material storage container is transferred; (4) The fourth robot grips and opens the second raw material storage container and loads the raw material into the graphite sintering table; then the graphite sintering table is transferred; The hollow shape of the graphite sintering table is cylindrical, and the outer surfaces of both ends of the graphite sintering table have raised annular steps; (5) The fifth manipulator clamps the graphite sintering table and places it on the bracket at one end of the conveyor belt, closes the box door, evacuates the box, and drives the bracket to the positive and negative connection positions of the power supply through the conveyor belt. The positive and negative poles of the power supply are respectively connected to the two ends of the graphite sintering table. The temperature meter is aimed at the middle of the graphite sintering table for continuous temperature measurement, and then current is applied to heat the middle of the sintering table at a rate of 20,000 degrees Celsius per second to 700 degrees Celsius and maintain it for 1 second, thereby performing Joule thermal shock; then, it reaches the other end of the conveyor belt under the drive of the conveyor belt; (6) The sixth robot clamps the graphite sintering table from the bracket and unloads the material.

[0024] (7) The seventh manipulator holds the tooling and extends from one end of the graphite sintering table to push out the other end of the finished graphite sintering table. The cross-sectional shape of the tooling is adapted to the shape of the openings at both ends of the graphite sintering table. In this embodiment, Fig. 9 In a, the shapes of the openings at both ends of the graphite sintering table are circular, and the cross-sectional shape of the tooling is also circular, that is, the tooling is in the shape of a round stick.

[0025] The metal anchoring functional groups (such as -OH and -COOH) in CNW prepared by the above method, as well as the ultrafast heating and strong quenching characteristics of the HTS method, synergistically promoted the successful synthesis of metal nanoparticles. The prepared Pt nanocatalyst (η10 mA cm -2 = 51.8 mV) shows a higher voltage than that of the Pt catalyst prepared in the tube furnace (η10 mA cm^ -2= 169.4 mV) and superior catalytic hydrogen evolution reaction (HER) performance. This rapid and versatile method paves the way for nanofabrication to produce high-quality metal nanoparticles, thereby expanding the range of applications in energy conversion and electrocatalysis.

[0026] The existing equipment on a single test bench can only process 0.5g of sample at a time, but after batch production, it can process kilograms of samples at a time, greatly improving experimental and production efficiency.

[0027] Example 3 In this embodiment, coconut shells were ground into fine granular coconut shell powder using a mortar as a raw material.

[0028] like Figure 1 — Fig. 9 and Fig.14 — Fig.15 A Joule thermal shock method based on the above-mentioned Joule thermal shock automation device comprises the following steps: (1) A first raw material storage container (containing coconut shell powder) is grasped by a first robot and placed on a first tray, and then the first robot grasps and transfers the first tray; (2) The second manipulator grabs and places the first tray, then opens the first raw material storage container, takes the raw material from the first raw material storage container and places it on an electronic scale to weigh 1g of coconut shell powder to obtain the required amount and store it in the second raw material storage container; then the second raw material storage container is transferred; (3) The third robot grips the second raw material storage container and shakes it to fully mix the raw materials inside; then the second raw material storage container is transferred; (4) The fourth robot grips and opens the second raw material storage container and loads the raw material into the graphite sintering table; then the graphite sintering table is transferred; The graphite sintering table is in the shape of a rectangular parallelepiped, and the hollow shape of the graphite sintering table is a stepped shape with a large middle and small ends; (5) The fifth manipulator clamps the graphite sintering table and places it on the bracket at one end of the conveyor belt. The vacuum box door is closed. After evacuation, the bracket is driven by the conveyor belt to the positive and negative connection positions of the power supply. The positive and negative poles of the power supply are respectively connected to the two ends of the graphite sintering table. Then, current is applied to heat the middle part of the sintering table at a rate of 20,000 degrees Celsius per second to 550 degrees Celsius and maintain it for 10 seconds, thereby performing Joule thermal shock. Then, the conveyor belt drives the bracket to the other end of the conveyor belt. (6) The sixth robot clamps the graphite sintering table from the bracket and unloads the material.

[0029] (7) The seventh manipulator holds the tooling and extends from one end of the graphite sintering table to eject the other end of the finished graphite sintering table. The cross-sectional shape of the tooling is adapted to the shape of the openings at both ends of the graphite sintering table, such as Fig. 9 In b, in this embodiment, the shapes of the openings at both ends of the graphite sintering table are rectangular, and the cross-sectional shape of the tooling is also rectangular, that is, the tooling is in the shape of a cuboid.

[0030] After the above steps, coconut shell pre-carbonized powder is obtained.

[0031] Then, KOH powder and coconut shell pre-carbon are used as raw materials for further preparation. The specific process is as follows: (1) The first manipulator grasps the two required first raw material storage containers (containing KOH powder and coconut shell pre-carbon respectively) and places them on the first tray, and then the first manipulator grasps and transfers the first tray; (2) The second manipulator grabs and places the first tray, then opens a plurality of first raw material storage containers, takes raw materials from the plurality of first raw material storage containers and places them on an electronic scale for weighing, weighing 0.6 g of KOH powder and 0.2 g of coconut shell pre-carbonized powder to obtain the required amount and store it in the second raw material storage container; then the second raw material storage container is transferred; (3) The third robot grips the second raw material storage container and shakes it to fully mix the raw materials inside; then the second raw material storage container is transferred; (4) The fourth robot grips and opens the second raw material storage container and loads the raw material into the graphite sintering table; then the graphite sintering table is transferred; The graphite sintering table is in the shape of a rectangular parallelepiped, and the hollow shape of the graphite sintering table is a stepped shape with a large middle and small ends; (5) The fifth manipulator clamps the graphite sintering table and places it on the bracket at one end of the conveyor belt. The vacuum box door is closed. After vacuuming, argon gas is introduced. The gas is purged three times repeatedly. The bracket is driven by the conveyor belt to the positive and negative connection position of the power supply. The positive and negative poles of the power supply are respectively connected to the two ends of the graphite sintering table. Then, current is applied to heat the middle part of the sintering at a rate of 1100 degrees Celsius per second to 1200K and maintain it for 10 seconds, thereby performing Joule thermal shock. Then, it is driven by the conveyor belt to the other end of the conveyor belt. (6) The sixth robot clamps the graphite sintering table from the bracket and unloads the material.

[0032] (7) The seventh manipulator holds the tooling and extends from one end of the graphite sintering table to eject the other end of the finished graphite sintering table. The cross-sectional shape of the tooling is adapted to the shape of the openings at both ends of the graphite sintering table, such as Fig. 9 In b, in this embodiment, the shapes of the openings at both ends of the graphite sintering table are rectangular, and the cross-sectional shape of the tooling is also rectangular, that is, the tooling is in the shape of a cuboid.

[0033] In this embodiment, Joule thermal shock carbonization and HTS-KOH activation methods are used to synthesize active porous carbons (APCs) with a high specific surface area of ​​about 843 m²g⁻¹. Compared with the traditional heat treatment and KOH activation process that takes up to 2 hours, this method significantly improves the preparation efficiency and product performance of APCs. In the HTS process, the sample undergoes instantaneous Joule heating (heating rate is about 1100 K / s). Under high temperature and rapid quenching conditions, KOH quickly melts into small droplets, which promotes full reaction with carbon materials and forms uniformly distributed rich micropores. These micropores are controllable, dense and fine. The prepared HTS-APCs-based supercapacitors show an energy density of up to 25 Wh kg⁻¹ and a power density of 582 W kg⁻¹ in EMIMBF4 ionic liquid. This study believes that the proposed technology not only provides a new way to manufacture supercapacitors, but also greatly improves their energy density, opening up new possibilities for the development of energy storage materials.

[0034] The existing equipment on a single test bench can only process 0.5g of sample at a time, but after batch production, it can process kilograms of samples at a time, greatly improving experimental and production efficiency.
