Description

Technical Field

[0001] This invention relates to the field of catalyst preparation technology, and in particular to a reaction apparatus for ultrasonically assisted dispersion of carbon-supported catalysts. Background Technology

[0002] In the field of catalyst preparation, traditional processes often separate the dispersion of carbon materials and the loading of active substances into two steps. First, the carbon materials are dispersed in a reaction vessel to achieve a relatively uniform distribution, providing a foundation for subsequent loading of active substances. However, after dispersion, the material needs to be transferred to another high-temperature reaction vessel for loading of active substances. Under high-temperature conditions, the carbon materials are prone to further agglomeration, which not only undermines the uniformity achieved in the previous dispersion step but also negatively impacts the loading of active substances, leading to a decline in the performance of the carbon-loaded catalyst. Furthermore, this step-by-step approach increases process complexity, prolongs the preparation cycle, and raises production costs. The material transfer process may also introduce impurities or cause material loss, further affecting the quality and performance of the carbon-loaded catalyst. Therefore, there is an urgent need for a catalyst preparation apparatus that can simplify the process flow, improve the uniformity of carbon material dispersion, and enhance the loading of active substances. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this invention is to provide an ultrasonically assisted dispersion reaction device for carbon-supported catalysts, capable of both dispersing carbon materials and loading active substances. Furthermore, the carbon materials and the prepared carbon-supported catalyst are uniformly and thoroughly dispersed, improving the loading effect of active substances and effectively enhancing the performance of the carbon-supported catalyst, thus demonstrating strong practicality.

[0016] 1. This invention, through the use of an ultrasonic rod, can disperse materials within the reaction chamber. The combined use of a jacketed cavity and a heating device allows the heating device to heat the heat-conducting oil within the jacketed cavity, thereby heating the materials within the reaction chamber. This combination enables the dispersion of carbon materials and the loading of active substances within a single reaction vessel, eliminating the need for material transfer, simplifying the process, saving time and labor, avoiding impurities from entering the material and preventing material loss. Furthermore, the carbon materials and the prepared carbon-supported catalyst are uniformly and fully dispersed, improving the loading effect of the active substances and effectively enhancing the performance of the carbon-supported catalyst, making it highly practical.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings:

[0019] Figure 1 This is a schematic diagram of the structure of this utility model;

[0020] The components include: 1. Reaction vessel; 11. Reaction chamber; 12. Jacketed cavity; 2. Heating device; 3. Ultrasonic rod; 4. Circulation pipeline; 5. Pump body; 6. Magnetic element; 61. Magnetic actuator; 7. Controller; 71. Temperature measuring device. Detailed Implementation

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figure 1 The diagram shows a reaction apparatus for ultrasonically assisted dispersion of a carbon-supported catalyst according to this embodiment, used to prepare the carbon-supported catalyst. The apparatus includes a reaction vessel 1, a heating device 2, and an ultrasonic rod 3. The reaction vessel 1 includes an outer vessel and an inner vessel disposed inside the outer vessel. The inner vessel is made of a thermally conductive material. The outer wall of the outer vessel is covered with a layer of prior art thermal insulation material. A reaction chamber 11 is formed inside the inner vessel, and a sandwich cavity 12 is formed between the inner and outer vessels. The reaction chamber 11 is used to hold materials such as carbon materials and active substances for preparing the carbon-supported catalyst. A cover plate is detachably installed on the top of the reaction vessel 1. This cover plate can seal the top openings of the inner and outer vessels, thereby allowing the reaction chamber 11 and the sandwich cavity 12 to be opened and closed. The sandwich cavity 12 is filled with thermally conductive oil. The aforementioned heating device 2 is fixed to the reaction vessel 1 and is used to heat the heat-conducting medium. Specifically, the heating device 2 is a conventional spiral heating tube, which is arranged inside the jacket cavity 12 and surrounds the outside of the reaction cavity 11, extending spirally in the vertical direction. The end of the spiral heating tube is sealed through the outer wall of the reaction vessel 1, so as to protrude outside the reaction vessel 1. The aforementioned ultrasonic rod 3 is a conventional component of the prior art, capable of emitting ultrasonic waves. The ultrasonic rod 3 is inserted and fixed to the top cover plate of the reaction vessel 1 and inserted vertically inside the reaction cavity 11. The ultrasonic waves generated by the ultrasonic rod 3 can disperse the material in the reaction cavity 11.

[0023] In the specific structural design, the interlayer cavity 12 is formed on the radial outer side of the reaction cavity 11 and below the bottom of the reaction cavity 11, so that the bottom of the reaction cavity 11 can be heated.

[0024] A circulation pipe 4 is installed outside the reaction vessel 1. The first end of the circulation pipe 4 is connected to the upper part of the jacketed cavity 12, and the second end is connected to the lower part of the jacketed cavity 12. A pump body 5 is connected in series with the circulation pipe 4. This pump body 5 is a conventional oil pump. Driven by the pump body 5, the heat transfer oil in the lower part of the jacketed cavity 12 can be transported to the upper part of the jacketed cavity 12 via the circulation pipe 4. The heated heat transfer oil circulates up and down within the jacketed cavity 12 to achieve uniform heat transfer.

[0025] The reaction apparatus of this embodiment includes a magnetic stirring device. This magnetic stirring device is a conventional device in the prior art. Specifically, the magnetic stirring device includes a magnetic element 6 and a magnetic actuator 61. At least one magnetic element 6 is arranged inside the reaction chamber 11 and located below the ultrasonic rod 3. The magnetic actuator 61 is arranged below the bottom of the reaction vessel 1 and is used to drive the magnetic element 6 to rotate. The magnetic actuator 61 includes a motor and a magnet fixed to the drive end of the motor. The magnet is magnetically coupled with the magnetic element 6. When the motor drives the magnet to rotate, the magnetic poles of the magnet rotate. Since the like poles of the magnetic element 6 and the magnet repel each other, and the unlike poles attract each other, the magnetic element 6 is driven to rotate accordingly. During rotation, the magnetic element 6 stirs the material in the reaction chamber 11, thereby dispersing the material.

[0026] In this embodiment, the reaction apparatus includes a temperature measuring device 71 and a controller 7. The temperature measuring device 71 is a thermocouple, a technology known from the prior art. The number of temperature measuring devices 71 depends on the actual design. Specifically, the temperature measuring device 71 is fixed to the top of the reaction vessel 1, with its probe extending into the reaction chamber 11 to monitor the temperature within the chamber. When the material for preparing the carbon-supported catalyst is added into the reaction chamber 11, the temperature measuring device 71 is inserted into the material to detect its temperature. The aforementioned temperature measuring device 71 and heating device 2 are connected to the controller 7. The controller 7 automatically adjusts the heating power of the heating device 2 based on a comparison between the set temperature and the actual temperature monitored by the temperature measuring device 71, thereby precisely controlling the temperature of the heat transfer oil. Furthermore, the controller 7 automatically adjusts the power of the ultrasonic rod 3 based on the temperature of the heat transfer oil, ensuring that the localized high temperature generated by the ultrasonic rod 3 during operation is consistent with the temperature of the heat transfer oil, resulting in uniform heating of the material within the reaction chamber 11.

[0027] In practical use, carbon material is first added to reaction chamber 11. The ultrasonic rod 3 and magnetic stirring device are then activated. The ultrasonic waves emitted by the ultrasonic rod 3 and the rotation of the magnetic stirrer 6 disperse the carbon material evenly within reaction chamber 11. The heat transfer oil is heated to a preset temperature using heating device 2, and pump 5 is activated to circulate the heat transfer oil. Next, the active material is added to reaction chamber 11. The ultrasonic rod 3 and magnetic stirring device are activated again. The ultrasonic waves emitted by the ultrasonic rod 3 and the rotation of the magnetic stirrer 6 further disperse the carbon material and active material evenly within reaction chamber 11, thus preparing a carbon-supported catalyst. The above method enables the dispersion of carbon materials and the loading of active substances within a single reaction vessel 1, eliminating the need for material transfer, simplifying the process, saving time and effort, avoiding impurities from entering the material and material loss, and ensuring that the carbon materials and the prepared carbon-supported catalyst are evenly and fully dispersed, thus improving the loading effect of the active substances. The movement of the magnetic particle 6 within the reaction chamber 11 allows for thorough stirring and dispersion of the material at the bottom of the reaction chamber 11, further enhancing the uniformity of the dispersion of the carbon materials and the prepared carbon-supported catalyst, effectively improving the performance of the carbon-supported catalyst, and demonstrating strong practicality.

Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
