[0022] like Figures 1 to 8 As shown, the present invention provides a carbon dioxide capture and liquefaction device, comprising: The capture liquefaction device component 100 includes a liquefaction tank 1 and a liquid storage tank 11; The connecting component 200 includes a rectangular box 2. A connecting pipe 101 and a connecting pipe 2 1101 are fixedly mounted on the outer walls of the liquefied tank 1 and the liquid storage tank 11, respectively. The other end of the connecting pipe 2 1101 is fixedly connected to the rectangular box 2, and the other end of the connecting pipe 101 is clamped to the rectangular box 2. The fixing mechanism is fixedly mounted on one side of the rectangular box 2 and is located between the liquefaction tank 1 and the liquid storage tank 11; A limiting mechanism is fixedly mounted on one side of the rectangular box 2 and conflicts with the fixing mechanism; Among them, the fixing mechanism includes a driving component and a fixing component. The fixing component includes a disc 21 fixedly installed on the side of the rectangular box 2 close to the liquefied tank 1. A turntable 211 is rotatably installed on the outer wall of the disc 21. A circular groove is opened inside the turntable 211 and the groove is fixedly connected to the disc 21. Six movable blocks 22 are arranged inside the turntable 211. The six movable blocks 22 are all triangular in design; a groove 2101 is opened on one side of the disc 21, and the groove 2101 is designed in a regular hexagonal shape; a protrusion 221 is fixedly installed on the side close to the groove 2101 of each movable block 22, and each protrusion 221 is slidably connected to the groove 2101; six groups of slide grooves 2112 are opened on the outer wall of the turntable 211, and the six groups of slide grooves 2112 are fixedly installed on the outer wall of the turntable 211. They all extend into the circular groove of the turntable 211, and each slide groove 2112 is designed in an elongated strip shape; each movable block 22 is fixedly installed with a round rod 222 on the side away from the protrusion 221, and each round rod 222 passes through the corresponding slide groove 2112 and is slidably connected to the corresponding slide groove 2112, and each round rod 222 extends out of the outer wall of the turntable 211 and is fixedly sleeved with a limit ring 2221; the driving assembly includes a rotating rod 3 rotating on the outer wall of one side of the rectangular box 2, and a gear 31 and a knob 32 are fixedly sleeved on the outer wall of the rotating rod 3.

[0023] The above solution is adopted: the fluid connection between the liquefaction tank 1 and the liquid storage tank 11 is achieved through the connecting component 200, ensuring the smooth capture and liquefaction process of the carbon dioxide gas; the fixing mechanism and the limiting mechanism work together to ensure the stability of the device during operation, and the design of the turntable 211 in the fixing mechanism enables the movable block 22 to be flexibly moved between six different angles, which means that the device can adapt to connecting pipes 101 of different diameters; the combined design of the circular groove in the turntable 211 and the movable block 22 enables the movable block 22 to slide through the groove 2101, thereby accurately adjusting the angle of each movable block 22; The adaptability of the device is greatly improved, especially when connecting pipes of different diameters. The position of the movable block 22 can be adjusted through simple operation to ensure the sealing and firmness of the connecting pipes. This is crucial for fluid transmission during the carbon dioxide capture process. In particular, it can ensure efficient material exchange between the liquefied tank 1 and the liquid storage tank 11 under conditions of flow or pressure fluctuations. The rotation of the rotating rod 3 causes the gear 31 to engage with the tooth groove 2111 of the rotating disk 211, driving the rotating disk 211 to rotate, thereby driving the movement of the movable block 22, making the operation of the device simpler and more efficient. The setting of the knob 32 makes it easier for the operator to adjust the working state. The multi-angle and multi-functional adjustment mechanism not only improves the flexibility of the device, but also increases its working efficiency, especially in the ability to quickly adapt to changes in demand under different working conditions; at the same time, the compact design of the device also enables it to achieve high integration and efficient operation within a limited space, greatly reducing space occupancy and energy consumption; the setting of a fixing mechanism not only improves the efficiency of the capture and liquefaction process, but also improves the convenience and adaptability of operation through optimized structure and design, so that the device can maintain efficient and stable operation in different working environments; reduces operational complexity, improves the compatibility of the equipment and the overall performance of the system, especially in actual applications, the adaptability to different pipe diameters improves the practicality of the device.

[0024] like Figures 6 to 8 As shown, the limiting mechanism includes two fixed blocks 25 fixedly mounted on the outer wall of one side of the rectangular box 2, and a toggle rod 251 is rotatably mounted on the side where the two fixed blocks 25 are close to each other; a rectangular groove 23 and an arc groove 24 are respectively opened on one side of the rectangular box 2, and a rotating rod 231 is rotatably mounted inside the rectangular groove 23, and a connecting rod 252 is hingedly mounted on the outer wall of the rotating rod 231, and the connecting rod 252 is hinged to the toggle rod 251; the rotating rod 231 is J-shaped and the outer end of the hook is triangular, and the rotating rod 231 conflicts with the gear 31; an arc rod 253 is fixedly mounted on the outer wall of the toggle rod 251, and the arc rod 253 is slidably connected to the inner wall of the arc groove 24, and the other end of the arc rod 253 is elastically connected to the inner wall of the arc groove 24 by a spring 241.

[0025] The above scheme is adopted: two fixed blocks 25 are respectively fixed to the outer wall of one side of the rectangular box 2, and the toggle rod 251 is installed between the two fixed blocks 25, and the position adjustment is completed by linkage with the connecting rod 252 and the rotating rod 231; the toggle rod 251 is designed in an L-shape, which can be convenient for the operator to press and adjust during use; the rotating rod 231 is designed as a J-shaped structure, and the outer end of the hook is triangular in design, so that the rotating rod 231 can be in firm contact with the gear 31; the function of the gear 31 is to further drive the entire fixing mechanism by cooperating with the rotating rod 231 to ensure the uniform distribution of the clamping force of the movable block 22 in the fixing assembly; when the toggle rod 251 is operated, the arc rod 253 will slide and generate a force on the rotating rod 231 through the spring 241, so that the rotating rod 231 can accurately enter the locked state; in this process, the spring 241 will be appropriately compressed or elastically restored according to the use requirements to ensure that the adjustment mechanism can operate stably under different working conditions.

[0026] Working effect: Through the above design, the entire limiting mechanism can accurately control the clamping force of the connecting pipe 101 and avoid loosening due to external vibration or long-term use; especially the meshing design of the J-shaped rotating rod 231 and the gear 31, which makes the entire clamping system more uniform when applying force, avoiding the situation where one side is too tight or too loose; the design of the toggle rod 251 and the arc rod 253 makes it more convenient and efficient for operators to fix the connecting pipe 101; the sliding of the arc rod 253 and the inner wall of the arc groove 24 combined with the elastic action of the spring 241 ensures that each adjustment can be very smooth and precise, avoiding excessive mechanical friction or unnecessary adjustment difficulty; through the meshing of the gear 31 and the rotating rod 231, and the connection of the arc rod 253 and the arc groove 24, it can be ensured that the system will not cause the pipeline to loosen due to unexpected factors during long-term operation, which can effectively avoid the safety hazards caused by pipeline leakage.

[0027] The working principle and use process of the present invention: The liquefaction tank 1 and the liquid storage tank 11 are connected to the rectangular box 2 through the connecting pipe 101 and the connecting pipe 2 1101, so that the liquefied carbon dioxide enters the rectangular box 2 through the pipeline after being liquefied, completing the storage process.

[0028] In order to prevent the connecting pipe 101 from loosening due to external force, thereby causing carbon dioxide leakage; the staff toggles the toggle rod 251, so that the connecting rod 252 drives the rotating rod 231 to rotate; the other end of the toggle rod 251 drives the arc rod 253, causing it to slide in the arc groove 24 and squeeze with the spring 241, causing the spring 241 to contract; as the spring 241 contracts, the rotating rod 231 gradually moves away from the gear 31, thereby releasing the locked state with the gear 31, and completing the preparation work; by rotating the adjustment device, ensure that the connecting pipe 101 is fixed and prevented from loosening; the staff rotates the knob 32 to drive the rotating rod 3 and the gear 31 to rotate; the gear 31 drives the turntable 211 to rotate by engaging with the tooth groove 2111; the turntable 211 drives the slide groove 2112 to rotate, and the slide groove 2112 passes through the round rod 22 2 is connected with the sliding groove 2112, driving the movable block 22 and the protrusion 221 on the other side of the movable block 22 to slide along the groove 2101; the angle of the movable block 22 changes, so that one side of the movable block 22 is in close contact with the outer wall of the connecting pipe 101, thereby achieving clamping and fixing; during this process, the movable block 22 can evenly clamp the outer wall of the connecting pipe 101, ensuring its stability and not easy to loosen; ensuring that the rotating rod 231 is locked to prevent it from rotating due to external force or other factors; the staff releases the toggle rod 251, allowing the spring 241 to rebound; as the spring 241 rebounds, the toggle rod 251 drives the rotating rod 231 to contact the gear 31 again through the connecting rod 252; the rotating rod 231 re-engages with the gear 31, thereby ensuring that the rotating rod 231 is locked to prevent it from rotating, further fixing the stability of the connecting pipe 101.
