[0002] As global environmental issues become increasingly prominent, green, environmentally friendly, and efficient production processes have become a research hotspot in both industry and academia. Supercritical carbon dioxide foaming technology, as a novel green material processing technology, has garnered widespread attention in recent years. Its unique physicochemical properties enable SC-CO2 to replace traditional organic solvents in the foaming process, effectively reducing environmental pollution during production.

[0003] In the existing supercritical carbon dioxide injection system, the delivery pipe used to transport supercritical carbon dioxide is under high pressure for a long time. Although high-strength seals (such as PTFE sealing rings or metal seals) are often used at the pipe joints (such as flanges and joints) to ensure sealing, leakage points may also appear on the surface of the pipe itself. When a leakage point occurs, special tools need to be found to seal it, which is inefficient. Therefore, it is urgent to design a supercritical carbon dioxide foaming equipment that can quickly rescue and seal leakage points in the pipeline. Utility Model Content

[0022] Reference Figure 1-Figure 4A supercritical carbon dioxide foaming device includes a pipe body 1 and a first card seat 2 and a second card seat 3 sleeved on the surface of the pipe body 1. The first card seat 2 and the second card seat 3 are both semicircular arc structures. One end of the first card seat 2 and the second card seat 3 is hinged. The first card seat 2 and the second card seat 3 are both provided with an adjustable position sealing mechanism and a shovel assembly 6. The sealing mechanism includes a sealing block 12, a plurality of sliders 11, a plurality of first fastening bolts 9 and a second fastening bolt 10. The inner arc surfaces of the first card seat 2 and the second card seat 3 are both provided with a first slide groove 13 adapted to the sealing block 12. The sealing block 12 is slidably installed in the first slide groove 13. More specifically, as Figure 2 As shown, the sealing block 12 can slide circumferentially along the inner wall relative to the pipe body 1 in the first slide groove 13, or can slide radially (closer to or away from the pipe body 1), so that the sealing block 12 can follow the first clamping seat 2 and the second clamping seat 3 to reach any leakage point on the surface of the pipe body 1 to seal it, thereby improving the efficiency of the equipment in sealing leakage points.

[0023] The outer arc surfaces of the first card seat 2 and the second card seat 3 are both provided with a second slide groove 14 adapted to the slider 11, and the multiple sliders 11 are slidably installed in the second slide groove 14. Figure 2 As shown, the slider 11 needs to follow the position adjustment of the sealing block 12 on the circumferential surface of the pipe body 1, and the slider 11 slides in a circle along its arc in the second slide groove 14. Each slider 11 has an arc structure, and the second slide groove 14 is connected to the first slide groove 13. A plurality of limiting protrusions 15 are provided on one side of the sealing block 12. A limiting hole that penetrates its outer surface and matches the limiting protrusion 15 is opened on the surface of each slider 11. The plurality of limiting protrusions 15 are respectively inserted into the plurality of limiting holes and slidably connected thereto. A threaded groove is opened in each limiting hole. The second fastening bolt 10 and the plurality of first fastening bolts 9 respectively pass through the corresponding limiting holes and are threadedly connected thereto. One end of the second fastening bolt 10 is rotatably connected to one of the limiting protrusions 15, preferably the limiting protrusion 15 located in the middle position (see Figure 4 ).

[0024] When in use, the sealing block 12 moves freely in the first slide groove 13, and can be adjusted in the arc direction in the first slide groove 13, or the distance between it and the pipe body 1 can be adjusted under the adjustment of the first fastening bolt 9 and the second fastening bolt 10. More specifically, by sleeve-fitting the first clamping seat 2 and the second clamping seat 3 on the surface of the pipe body 1, when a leak occurs in the pipe body 1, the fastening sleeve 7 is loosened, and the first clamping seat 2 and the second clamping seat 3 can be moved to the leak point. During the movement, the cleaning shovel assembly 6 is used to clean the impurities on the surface of the leak point, so that the sealing block 12 can be closely attached to the leak point. Then adjust the sealing block 12 to align it with the leakage point, tighten the fastening sleeve 7 to fix the position of the first clamping seat 2 and the second clamping seat 3, and then tighten the second fastening bolt 10 and multiple first fastening bolts 9 in sequence to drive the sealing block 12 to fit more tightly with the pipe body 1. In this process, the sealing block 12 is first radially slid against the pipe body 1 by rotating the second fastening bolt 10, and then the corresponding limiting protrusions 15 are tightened by rotating multiple first fastening bolts 9, so that the sealing block 12 and the pipe body 1 fit more tightly. The sealing process is simple and convenient to operate, which improves the practicality of the equipment.

[0025] In order to allow the cleaning shovel assembly 6 to complete the cleaning of the surrounding area before plugging the leak point, in a specific embodiment, as shown in FIG. Figure 3 and Figure 4 As shown, the cleaning shovel assembly 6 includes a shovel blade 601 and a knife holder 602. The knife holder 602 is fixedly installed with multiple sliders 11 and can adjust its position on the surface of the pipe body 1 following the sealing block 12. The shovel blade 601 is fixedly installed on one side of the knife holder 602. The shovel blade 601 has an arc-shaped structure, and the curvature of the blade of the shovel blade 601 is adapted to the surface of the pipe body 1. When the first card seat 2 and the second card seat 3 are pushed to the vicinity of the leakage point, the shovel blade 601 is aligned with the leakage point, and the first card seat 2 and the second card seat 3 are driven back and forth to slide along the axial direction on the surface of the pipe body 1, thereby driving the shovel blade 601 to clean up the impurities near the leakage point, avoiding the need to find other tools for cleaning, thereby improving the practicality of the equipment.

[0026] A handle 4 is fixedly installed on the surface of the first card seat 2 and the second card seat 3. An adjustment slot is opened at the other end of the first card seat 2 and the second card seat 3. A movable pin 5 is rotatably installed in the adjustment slot of the first card seat 2. A fastening sleeve 7 is threadedly sleeved on the surface of the other end of the movable pin 5, and a pull ring 8 is fixedly installed on the end of the fastening sleeve 7.

[0027] During use, by setting the cleaning shovel assembly 6 and setting the shovel blade 601 to adapt to the outer diameter of the pipe body 1, the cleaning effect is better. By setting the movable pin 5 and the fastening sleeve 7, the first clamping seat 2 and the second clamping seat 3 are conveniently disassembled and assembled. When moving the first clamping seat 2 and the second clamping seat 3, it is only necessary to loosen the fastening sleeve 7 without separating the first clamping seat 2 from the second clamping seat 3. Then, the handle 4 can be pulled to drive the cleaning shovel assembly 6 to clean the surface of the pipe body 1 at the leakage point, so that the sealing block 12 can fit more closely with it, thereby improving the convenience and practicality of the equipment.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
