Description

Technical Field

[0001] This invention relates to the field of experimental equipment technology, specifically to an experimental observation device for the in-situ synthesis of Fe2O3. Background Technology

[0002] Iron oxide (Fe2O3) is a common inorganic compound with a wide range of applications, including catalysts, electronic materials, magnetic materials, pigments, energy storage and conversion materials, etc. In-situ synthesis is a method that directly generates and forms products in a reaction system. By precisely controlling the reaction conditions, the properties of the products can be adjusted and optimized at the microscopic level.

[0003] Existing Fe2O3 preparation equipment is typically container-based and relies on manual operation and recording. It lacks protective structures, has limited functionality, and cannot meet diverse experimental needs. Furthermore, it lacks precision in controlling experimental conditions and often fails to accurately monitor and record experimental phenomena. This lack of effective recording methods is detrimental to the in-situ synthesis of Fe2O3, as visual information of the reaction process is crucial for scientific research and teaching. In addition, existing equipment often lacks effective light source adjustment mechanisms, failing to meet the needs of experiments under different light source conditions. During the synthesis reaction, it is essential to ensure the cleanliness of the experimental materials and prevent contact with foreign objects, but this presents significant technical challenges for in-depth experimental recording. Therefore, a more in-depth, comprehensive, and detailed experimental observation device is urgently needed. Summary of the Invention

[0035] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0036] Please see Figures 1 to 12As shown in the embodiment of this application, an experimental observation device for the in-situ synthesis of Fe2O3 is provided, including a support frame 1; it also includes a reaction chamber 2, a light source adjustment mechanism 3, a hanging column mechanism 7, a gas storage tank 9, a container 10, a door 11, and a connecting branch pipe 13. The reaction chamber 2 is hollow and has a partition inside, providing multiple reaction sites, each of which is equipped with a container 10; the light source adjustment mechanism 3 is fixedly installed on the side wall of the reaction chamber 2, and is used to adjust the light source entering the reaction chamber 2; the hanging column mechanism 7 is fixedly installed on the reaction chamber 2. Above each container 10; connecting branch pipes 13 are arranged in each reaction site, one end of the connecting branch pipe 13 is connected to the light source adjustment mechanism 3, and the other end of the connecting branch pipe 13 is connected to the hanging column mechanism 7, for providing an irradiation light source to the hanging column mechanism 7; the gas storage tank 9 is fixedly installed on the bottom outer wall of the reaction chamber 2, and the output end of the gas storage tank 9 is connected to the connecting branch pipe 13, for providing an impact gas source to the hanging column mechanism 7; there are two doors 11, one door 11 corresponds to at least two containers 10, and the other door 11 corresponds to another container 10.

[0037] As can be seen from the above technical solution, the experimental observation device for the in-situ synthesis of Fe2O3 provided in this application achieves comprehensive monitoring and precise control of the experimental process. It includes a hollow reaction chamber 2 with internal partitions separating multiple reaction sites for simultaneous observation of multiple experiments. Each reaction site is equipped with a container 10 to conduct various Fe2O3 preparation reactions using the same or different schemes. A light source adjustment mechanism 3 is fixed to the side wall of the reaction chamber 2, which can adjust the light source entering the reaction chamber 2 to meet the needs of experiments under different light source conditions. It can also explore the influence of different types and intensities of light sources on the experimental reaction process and results. The reaction chamber 2 also contains... A hanging column mechanism 7 is installed above each container 10, which can observe and record the reaction process in real time and project a light source into the container 10. A connecting branch pipe 13 is connected to the light source adjustment mechanism 3 and the hanging column mechanism 7 to provide an illumination light source for the hanging column mechanism 7. The gas storage tank 9 is located on the bottom outer wall of the reaction chamber 2, and its output end is connected to the connecting branch pipe 13 to provide an impact gas source for the hanging column mechanism 7. This ensures that the experimental materials are clean and free from contact with foreign objects to achieve targeted impact. At the same time, it can also provide the reactants with a certain amount of oxygen to observe the effect of oxygen in different containers 10 on the reaction formation, which is convenient for further non-contact and non-polluting observation and targeted impact agitation of the samples.

[0038] In addition, this device is equipped with two doors 11, one door 11 corresponding to at least two containers 10, and the other door 11 corresponding to another container 10. The containers can be arranged on the support plate 14 for easy transfer and multiple experimental operations. The two inner cavities allow experimenters to carry out different preparation experiments while being isolated from each other without interference. Therefore, this device enables comprehensive monitoring of the Fe2O3 synthesis reaction, thereby improving the accuracy and efficiency of experimental data acquisition. Through this device, experimenters can observe the experimental process more deeply, comprehensively, and meticulously, improving experimental accuracy and meeting diverse experimental needs.

[0039] Please see Figures 1-6 As shown, in some examples, the light source adjustment mechanism 3 further includes: an outer frame 31, a light inlet 32, a condenser 33, a condenser lens 34, a light receiver 35, a filter assembly 36, and a supplementary light 37. The outer frame 31 is fixedly mounted on the side wall of the reaction chamber 2. The outer frame 31 is hollow, and the outer wall of the outer frame 31 has light inlets 32 corresponding to the number of reaction sites. The condenser 33 is fixedly mounted in the inner cavity of the outer frame 31 and corresponds to the position of the light inlets 32. The condenser 33 has a central opening. A vertical through-channel has a condenser lens 34 at the end of the condenser 33 away from the light inlet 32, which is used to further focus the light source in the condenser 33; a light receiver 35 is arranged at the end of the connecting branch pipe 13, which is used to deliver the focused light source; a filter assembly 36 is detachably inserted into the inner cavity of the outer frame 31, which is used to adjust the light source entering the reaction chamber 2; and a supplementary light 37 is fixedly installed on the inner wall of the outer frame 31 between the light inlet 32 ​​and the condenser 33, which is used to provide supplementary light to the condenser 33.

[0040] Understandably, the light source adjustment mechanism 3 is responsible for adjusting and providing the light source entering the reaction chamber 2. It mainly consists of an outer frame 31, a light inlet 32, a condenser hood 33, a condenser lens 34, a light receiver 35, a filter assembly 36, and a supplementary light 37. The outer frame 31 is fixed to the side wall of the reaction chamber 2. The outer wall of the outer frame 31 has light inlets 32 corresponding to the number of reaction sites, which are used to introduce external natural light sources (the outer frame 31 can be placed in a position with sufficient natural light). A vertical through-channel is provided in the middle, which is used to insert and block the incoming light source. A condenser lens is provided at the end away from the light inlet 32. 34 is used to further concentrate the light source and enhance its intensity. The light receiver 35 is arranged at the end of the connecting branch pipe 13 to receive and transmit the focused light source in the condenser 33 and then deliver it to the target position. When the filter assembly 36 is inserted into the inner cavity of the outer frame 31, it can adjust the light source entering the reaction chamber 2 to meet the light source requirements under different experimental conditions. The supplementary light 37 is fixed on the inner wall of the outer frame 31 between the light inlet 32 ​​and the condenser 33. When the external light source is insufficient, the supplementary light 37 can provide supplementary light and additional light source supplementation. It is different from natural light and can also explore the influence of different light sources on the reaction.

[0041] Please see Figures 4 to 6 As shown, in some examples, the fill light 37 is further described as a stepless fill light 37, and each fill light 37 is connected to a sliding stepless adjustment switch 12 for turning on, off, or fine-tuning the intensity or color of the light source emitted by the fill light 37.

[0042] In this example, the light source adjustment mechanism 3 further enhances its supplementary lighting capability by being equipped with stepless supplementary lights 37. Each supplementary light 37 is connected to a sliding stepless adjustment switch 12, which increases the flexibility of the light source intensity. Through the setting of the stepless adjustment switch 12, the user can achieve precise control of the light in the reaction chamber 2 by sliding the switch. The stepless supplementary lights 37 can be used to precisely adjust the light intensity or color, adding more flexibility to the light source adjustment mechanism 3. When the natural light source is insufficient or the light color is not suitable for a specific reaction and observation, the user can slide the stepless adjustment switch 12 to fine-tune the brightness of the supplementary lights 37 or change their color to provide the most suitable light environment.

[0043] Please see Figures 4 to 6 As shown, in some examples, the filter assembly 36 further includes: a pull-out plate 361, which is vertically pullable and snapped into the inner cavity of the outer frame 31. The pull-out plate 361 extends through the entire through channel. The pull-out plate 361 is provided with a plurality of circular slots 362. Each slot 362 is provided with a removable filter 363. Each filter 363 is located in the through channel and blocks the converging light source of the light-concentrating cover 33.

[0044] In this example, it is understood that the filter assembly 36 includes a pull-out plate 361 that can move freely within the through-channel. The pull-out plate 361 is provided with multiple circular slots 362 and filters 363. Each filter 363 is located within the through-channel and can be used to block the converging light source of the light-collecting mask 33 when natural light is strong.

[0045] In addition, the filter 363 in this example can also filter specific light sources, allowing only light of a specific wavelength to pass through. Users can select different types of filter 363 according to their actual needs to adapt to different light source requirements and reaction conditions.

[0046] Please see Figure 4 and Figure 7 As shown, in some examples, the connecting branch pipe 13 further includes: a pipe wall 131, the two ends of which are respectively connected to the condenser lens 34 and the hanging column mechanism 7. The inner side of the pipe wall 131 is provided with a light guide 132 and an air supply pipe 133, wherein the light guide 132 is connected to the light receiver 35 and the air supply pipe 133 is connected to the air storage tank 9. The inner cavity of the pipe wall 131 is also provided with a filler 134 for isolating the light source and fixing the light guide 132 and the air supply pipe 133.

[0047] In this example, it can be understood that the connecting branch pipe 13 includes a pipe wall 131. The connecting branch pipe 13 serves as an intermediate component, connecting the condenser lens 34 and the hanging column mechanism 7 together. The pipe wall 131 covers the light guide tube 132 and the gas supply pipe 133. The light guide tube 132 is connected to the light receiver 35. The light guide tube 132 mainly receives and guides the light source into the container 10. The gas supply pipe 133 is connected to the gas storage tank 9 and is used to guide and regulate the gas flow output to achieve oxygen supply and impact disturbance for positioning the test sample. In the inner cavity of the pipe wall 131, a filler 134 is also provided. The filler 134 has two main functions: first, to isolate the light source and ensure that the light source does not directly irradiate the pipe wall 131 or cause other damage; second, to fix the light guide tube 132 and the gas supply pipe 133, so that the fixed light guide tube 132 and the gas supply pipe 133 remain stable inside the connecting branch pipe 13 and will not move or deform due to external forces or other factors.

[0048] Please see Figure 3 Figure 8 Figure 10 and Figure 12As shown, in some examples, the hanging column mechanism 7 further includes: a projection column 71, which is fixedly installed at the upper center of the container 10; a rotating component 72 is provided on the outer wall of the bottom end of the projection column 71; wherein, a small motor 726 and a drive wheel 727 are arranged on the outer wall of the rotating component 72, and the drive wheel 727 is locked to the output end of the small motor 726 by a coupling, and the small motor 726 is used to drive the rotating component 72 to rotate horizontally.

[0049] It should be noted that the suspended column mechanism 7 provided in this example includes a projection column 71, which is fixedly placed at the center of the upper part of the container 10, so that the projection column 71 occupies a central position above the container 10 and can effectively illuminate the entire area inside the container 10. On the outer wall of the bottom end of the projection column 71, a rotating component 72 is provided. The rotating component 72 can rotate around the projection column 71 within a certain range, thereby driving the image acquisition component to acquire different reaction positions in the container 10 for detailed observation. At the same time, the rotation of the rotating component 72 also synchronously adjusts the emission position of the impact gas source. The impact position of the gas source and the image acquisition position move synchronously and adjacently, which makes it convenient for the staff to observe the reaction position on the display 5 and obtain the image information after the current position receives the impact and disturbance, and facilitates precise control of the suspended column mechanism 7. The display 5 can be fixed to the outer wall of the reaction chamber by the side frame 4.

[0050] Specifically, a small motor 726 and a drive wheel 727 are arranged on the outer wall of the rotating component 72. The function of the small motor 726 is to drive the rotating component 72 to rotate horizontally. The drive wheel 727 is rotated by the control of the motor. At the same time, the horizontal rotation of the rotating component 72 is achieved by the friction between the drive wheel 727 and the projection column 71. Therefore, the small motor 726 can accurately adjust the rotation angle and speed of the projection column 71, thereby achieving precise control of the image acquisition area.

[0051] Please see Figure 10 As shown, in some examples, the rotating component 72 is further provided with: a limiting ring 721, a rotating ring 722, a hinge seat 723, a small push rod 724, and an image acquisition component 725. At least one limiting ring 721 is fixedly installed at the bottom of the outer wall of the projection column 71. The limiting ring 721 is used to restrict the rotating component 72 from rotating in the horizontal direction. The outer wall of the limiting ring 721 is in contact with the drive wheel 727. The rotating ring 722 is rotatably arranged outside the limiting ring 721. The rotating ring 722 is coaxially arranged with the projection column 71. The hinge seat 723 is provided on the lower half of the outer wall of the rotating ring 722. The small push rod 724 is movably installed on the outer side of the upper half of the outer wall of the rotating ring 722. The image acquisition component 725 is rotatably installed on the outer side of the hinge seat 723. The upper half of the image acquisition component 725 is movably connected to the telescopic end of the small push rod 724.

[0052] In this example, the specific structure of the rotating component 72 is provided. The rotating component 72 is provided with at least one limiting ring 721. The main function of the limiting ring 721 is to restrict the horizontal rotation of the rotating component 72, forming a limiting structure to prevent it from falling off. Additionally, the outer wall of the limiting ring 721 contacts the drive wheel 727. Through this contact and friction, the rotating component 72 achieves horizontal rotation when the small motor 726 rotates. The rotating ring 722 is coaxially arranged with the projection column 71, which makes the rotation smoother and ensures the projection position is centered. The outer wall of the rotating ring 722 is provided with a hinge seat 723 connected to the small push rod 724. The push rod allows the operator to adjust the tilt angle of the image acquisition unit 725 according to the desired observation position, enabling it to observe the reactants at different distances from the center point of the container 10. The image acquisition unit 725 is rotatably mounted on the outside of the hinge base 723 and can achieve horizontal rotation through the drive of the small motor 726 and the drive wheel 727. At the same time, the image acquisition unit 725 can rotate or move under the control of the small push rod 724, increasing the flexibility of the image acquisition unit 725. The acquisition angle and position can be changed as needed to achieve comprehensive and multi-angle acquisition of image information of the reaction situation of the container 10.

[0053] Please see Figure 8 and Figure 10 As shown, in some examples, the projection column 71 further includes: a column 711, a reflector 712, and a concave lens 713. The column 711 is fixedly arranged at the upper middle position of the container 10. The bottom end of the column 711 is in a cavity state. The reflector 712 facing the container 10 is disposed in the cavity. The other end of the light guide 132 extends to the inside of the reflector 712. The concave lens 713 is also disposed in the inner cavity of the column 711 below the reflector 712.

[0054] In this example, it should be noted that the projection column 71 mainly consists of a column 711, a reflector 712, and a concave lens 713. The column 711 is fixedly arranged in the upper middle position of the container 10, so that the projection column 71 can fully illuminate the container 10. The bottom end of the column 711 is provided with a reflector 712 facing the container 10. The function of the reflector 712 is to reflect the light source, so that the light can be more concentrated and effectively irradiated into the container 10. The other end of the light guide 132 extends to the inside of the reflector 712, which can better guide the light source into the reflector 712, so that the light can be effectively reflected towards the container 10. The light guide 132 can be further configured as an optical fiber, or any material that can have the function of light conduction. In the inner cavity of the column 711 below the reflector 712, a concave lens 713 is also provided. The function of the concave lens 713 is to focus or diffuse the light. According to the design and position of the concave lens 713, the propagation direction and illumination range of the light can be changed.

[0055] Please see Figure 11 As shown, in some examples, the image acquisition device 725 further includes: a cylinder 7251, which is rotatably mounted on the outside of the hinge 723; the upper half of the image acquisition device 725 is movably connected to the telescopic end of the small push rod 724; a macro camera 7252 and a nozzle 7253 are provided at the bottom of the inner cavity of the cylinder 7251; an air supply hose 7255 is also connected between the air supply pipes 133 of the cylinder 7251; and an air delivery pipe 7254 connected to the air supply hose 7255 and the nozzle 7253 is also provided in the inner cavity of the cylinder 7251.

[0056] This example provides the specific structure of the image acquisition component, wherein the image acquisition component 725 mainly includes a cylindrical body 7251, which is rotatably mounted on the outside of the hinge seat 723, enabling rotation within a certain range and increasing the angle and range of image acquisition. The upper part of the image acquisition component 725 is movably connected to the telescopic end of the small push rod 724, allowing the image acquisition component 725 to move or rotate under the control of the small push rod 724, thereby improving the more comprehensive multi-angle image acquisition effect.
