In addition, dry ice can also be used in the field of refrigerated transportation, and can also be used to create stage effects.

[0003] When dry ice is produced, gaseous carbon dioxide is usually compressed to reduce its volume to form liquid carbon dioxide, and then the liquid carbon dioxide is transported to a dry ice machine to form dry ice.

Solid substances such as ice crystals attached to the left filter plate and the right filter plate can be cleaned, which is convenient to use.

DETAILED DESCRIPTION

[0046] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The embodiment of the present invention specifically provides a carbon dioxide compression device for making dry ice, please refer to Figure 1 , including a frame 1 and a detection component 2.

[0048] Among them, a carbon dioxide compression component 11 is fixedly provided on the panel surface of the rack 1. A delivery pipe 12 on the carbon dioxide compression component 11 for connecting to an external pipeline passes through the bottom surface of the panel of the rack 1. The delivery pipe 12 is used to connect to an external dry ice production input / output pipeline, so that the gaseous raw material is compressed into a liquid state through the carbon dioxide compression component 11 and transported outward. Since the carbon dioxide compression component 11 and related compression technologies are both existing mature technologies, they are not described in detail here. The detection component 2 is arranged outside the carbon dioxide compression component 11 at intervals, and the carbon dioxide compression component 11 is automatically detected by the detection component 2 to see if there is any carbon dioxide leakage, and the heat emitted during compression is used for waste heat utilization;

[0049] For details, please refer to Figure 1 and Figure 2 The detection components 2 are symmetrically arranged at two locations outside the carbon dioxide compression component 11, so that when the carbon dioxide compression component 11 is used in daily life, the two detection components 2 can be placed close to each other to cover the periphery of the carbon dioxide compression component 11, so as to facilitate the quick detection of carbon dioxide leakage thereon and improve the efficiency of waste heat utilization;

[0050] The detection component 2 includes a recovery bin 3, a transition bin 4, a sealing side plate 5, a search component 6 and a positioning component 7. The bottom end of the recovery bin 3 is slidably matched with the frame 1, so that the two recovery bins 3 can move closer to or farther from each other on the outside of the carbon dioxide compression component 11. The transition bin 4 is fixed at the top of the recovery bin 3, and the sealing side plate 5 is fixed at the front and rear sides of the transition bin 4. The outer side of the sealing side plate 5 is fixed to the recovery bin 3, so that when the two recovery bins 3 are close to each other, the transition bins 4 and the sealing side plates 5 at the left and right ends can contact and close, so that the surrounding side of the carbon dioxide compression component 11 can be covered and closed by the recovery bin 3, the transition bin 4 and the sealing side plates 5;

[0051] Among them, the search component 6 is installed on one side of the recovery bin 3 close to the carbon dioxide compression component 11, and the positioning component 7 is installed on the recovery bin 3 and the transition bin 4. When a carbon dioxide leakage is detected, the search component 6 can quickly detect the area of ​​carbon dioxide leakage, so that the staff can obtain the area information at the first time to improve the timeliness and efficiency of maintenance, and the positioning component 7 cooperates with the search component 6 to improve the accuracy of locating the leakage area.

[0052] For further information, please refer to Figure 3 The search component 6 includes a serpentine guide rail 61, a search vehicle 62 that moves along the serpentine guide rail 61, a traction component 63 disposed on the serpentine guide rail 61, and a bracket 64 with one end fixedly connected to the serpentine guide rail 61, and the other end of the bracket 64 is fixed to the transition chamber 4, so that the serpentine guide rail 61 can be stably installed under the transition chamber 4, so that the search vehicle 62 can automatically move along the serpentine guide rail 61 under the drive of the traction component 63, and detect the carbon dioxide concentration on the outer side of the carbon dioxide compression component 11;

[0053] During detection, the search vehicle 62 will move back and forth along the initial end and the end of the serpentine guide rail 61. After completing multiple strokes, the number of multiple strokes is greater than the number of two reciprocating movements. By comparing the detection data, information about areas with higher carbon dioxide concentrations can be obtained. This method can be done through existing programming technology in a timely manner and will not be described in detail here, thereby providing maintenance reference for staff and facilitating timely maintenance and troubleshooting.

[0054] For details, please refer to Figure 4 The serpentine guide rail 61 includes a guide rail body 611 fixedly connected to the bracket 64 on the outside, a through groove 612 opened inside the guide rail body 611, a slide groove 613 opened on the side of the guide rail body 611 close to the carbon dioxide compression component 11, and a fixed component 614 fixed inside the guide rail body 611. The through groove 612 is communicated with the slide groove 613, so that the search vehicle 62 can stably move along the slide groove 613 at the head and tail ends of the guide rail body 611 to perform leakage detection on the carbon dioxide compression component 11. The search vehicle 62 is arranged on both sides of the carbon dioxide compression component 11, which can improve the detection accuracy and efficiency.

[0055] Among them, the search vehicle 62 includes a first detection module 621, a moving component 622 that slides along the slide groove 613, and a matching component 623 installed on the moving component 622 near one end of the fixed component 614. The outer side of the first detection module 621 is fixed to the moving component 622, so that under the drive of the moving component 622, the first detection module 621 can be displaced along the guide rail body 611, so that the leakage position of the outer area of ​​the carbon dioxide compression component 11 is searched through the position movement of the first detection module 621, and after the area is confirmed, the position of the first detection module 621 can be temporarily fixed through the fixed component 614.

[0056] When implementing, please refer to Figure 4 and Figure 5 The moving assembly 622 includes a mounting seat 624, a slider 625 slidably connected to the slide groove 613 on the outside, and a moving seat 626 fixed to a side of the slider 625 away from the mounting seat 624. The outside of the mounting seat 624 is fixedly connected to the slider 625. Balls 627 are rollingly installed between adjacent surfaces of the mounting seat 624 and the moving seat 626. The mounting seat 624 and the moving seat 626 are respectively rollingly matched with the guide rail body 611 and the through groove 612 through the ball 627, so that the slider 625 can slide quickly along the slide groove 613, and the sliding convenience is improved by the ball 627, so as to facilitate the movement of the first detection module 621;

[0057] Among them, the matching component 623 includes a mounting groove 628 opened on the movable seat 626, a telescopic disk 629 that is in sliding contact with the mounting groove 628 on the outside, a detector 6210 embedded in the mounting groove 628, and a spring 6211 whose two ends are respectively fixedly connected to the mounting groove 628 and the telescopic disk 629. The detection end of the detector 6210 is fixed to the telescopic disk 629. The detector 6210 is a contact sensor, and its detection end is in contact with the telescopic disk 62. The material of the telescopic disk 629 is ferromagnetic material. The type of the fixed component 614 is an electromagnetic coil. When the first detection module 621 determines the leakage area, it will energize the fixed component 614 and generate magnetic force, so that the telescopic disk 629 extends toward the fixed component 614 and contacts the fixed component 614 with magnetic force to be temporarily fixed. Through the detector 6210, the position state of the telescopic disk 629 can be known, that is, whether it is moved outward or reset in place, so as to improve the use accuracy of the telescopic disk 629.

[0058] For further information, please refer to Figure 2 and Figure 6The traction assembly 63 includes a protective shell 631 fixedly connected to the sealing side plate 5 on the outside, a through hole 632 opened on the protective shell 631, a retracting assembly and a driving assembly installed in the protective shell 631, and the interior of the protective shell 631 is connected to the through groove 612 through the through hole 632. There are two retracting assemblies, which are respectively located at the upper and lower ends of the serpentine guide rail 61, so that the search vehicle 62 is displaced and pulled in the left and right directions through the two retracting assemblies. A limiting assembly for limiting the movement of the retracting assembly is also provided in the retracting assembly at the upper end.

[0059] The retracting assembly includes a mounting frame 641 with both ends fixedly connected to the protective shell 631, a rotating rod 642 rotatably connected to the mounting frame 641 on the outside, and a traction rope 643 wound on the rotating rod 642. One end of the traction rope 643 is fixed to the rotating rod 642, and the other end is fixedly connected to the moving seat 626 after passing through the through hole 632. The traction rope 643 is in sliding contact with the inner wall of the through groove 612, and the traction rope 643 is kept in a taut state, so that the left and right ends of the moving seat 626 are respectively connected to the traction ropes 643 on the two retracting assemblies. When one of the rotating rods 642 rotates, it will drive the moving seat 626 to move closer to it through the traction rope 643, and make the traction rope 643 in the other direction extend.

[0060] Specifically, the driving assembly includes a first chuck 651 fixedly mounted on the top of the rotating rod 642, a second chuck 652 spaced above the first chuck 651, a motor 654 disposed on the first chuck 651 and the second chuck 652 and a clamping plate 653 and an output shaft fixedly connected to the second chuck 652. The first chuck 651 and the second chuck 652 are coaxially arranged. When the motor 654 rotates, it drives the second chuck 652 to rotate.

[0061] The outer side of the motor 654 is fixedly connected to the push plate 655, the upper surface of the push plate 655 is fixed to the output end of the push cylinder 656, and the outer side of the push cylinder 656 is fixedly connected to the protective shell 631 through the mounting plate 657. When the rotary rod 642 needs to be rotated, the motor 654 can be pushed by the push cylinder 656, so that the motor 654 drives the second chuck 652 to contact the first chuck 651, so that the clamping plates 653 on the two chucks are clamped with each other, so that the second chuck 652 drives the first chuck 651 to rotate, so as to rotate the rotary rod 642;

[0062] Among them, since the search vehicle 62 is easy to move down along the arc curve due to its own weight if it is at the turning point of the slide 613, it is necessary to brake the upper rotating rod 642 through the limiting component so that the upper rotating rod 642 will rotate to release the line only when the downward pulling force on the search vehicle 62 is greater than the braking force of the limiting component on the rotating rod 642.

[0063] The limiting component includes a blocking wheel 661 coaxially fixed to the outer side of the rotating rod 642, a groove 662 opened along the circumferential direction of the blocking wheel 661, a brake plate 663 with one end abutting against the groove 662, a rotating column 664 fixedly connected to the brake plate 663 at the bottom end, a support 665 fixed to the inner side of the protective shell 631 and a torsion spring 666 arranged between the brake plate 663 and the support 665. The top of the rotating column 664 is rotatably connected to the support 665, so that when the upper rotating rod 642 is pulled by the traction rope 643 below to release the line, the rotational force on the brake plate 663 is controlled by the torsion spring 666, and the rotational force is less than the pulling force of the traction rope 643, and greater than the downward force of the search vehicle 62 due to its own weight, thereby achieving a braking effect, so that when the blocking wheel 661 rotates, it will push the brake plate 663 to rotate and reset the brake plate 663 through the torsion spring 666.

[0064] Further, to achieve waste heat recovery, please refer to Figure 2 , Figure 3 and Figure 7 The recovery bin 3 includes a first bin body 31, a first fan 32 embedded in the first bin body 31, a cooling coil 33 fixedly arranged inside the first bin body 31, and an interface pipe 34 fixedly connected to the cooling coil 33. The interface pipe 34 is respectively connected to the input port and the output port of the cooling coil 33, and the outer side of the interface pipe 34 is fixedly fitted with the first bin body 31. A hose 35 is fixedly installed at the outer end of the interface pipe 34. The hose 35 meets the moving stroke requirement of the first bin body 31 to avoid jamming. The bottom end of a bin body 31 is fixedly connected to the electric guide rail 36, and the first bin body 31 slides on the frame 1 through the guide rod 37. The electric guide rail 36 and the guide rod 37 are fixedly arranged on the bottom surface of the frame 1 panel. The surface of the frame 1 is provided with an opening 13. The bottom end of the first bin body 31 is connected to the electric guide rail 36 and the guide rod 37 through the opening 13, so that under the drive of the electric guide rail 36, the outer side of the first bin body 31 is fixed to the transition bin 4 as a whole, and the outer wall of the first bin body 31 is fixedly connected to the sealing side plate 5;

[0065] The bottom surface of the sealing side plate 5 is in sliding contact with the panel of the frame 1, so that when the two first bin bodies 31 move closer, the sealing side plates 5 at both ends and the transition bin 4 can be closed, so that the outside of the carbon dioxide compression component 11 can be in a relatively closed space, so that the heat it dissipates can be concentrated and sucked into the first bin body 31 by the first fan 32, and after the circulating cooling water is sent into the cooling coil 33 through the hose 35, the cooling water can be heated by heat exchange through the waste heat, so as to achieve the purpose of waste heat utilization and help compression and heat dissipation, and at the same time, it is also convenient to concentrate the air around the carbon dioxide compression component 11 for easy detection.

[0066] Specifically, the first bin body 31 and the transition bin 4 are hollow structures, and the two transition bins 4 are connected by a central component 8 and a connecting component 9, so that after the two transition bins 4 are connected by movement, the gas absorbed in the two first bin bodies 31 can be centrally detected and discharged by the central component 8 and the connecting component 9;

[0067] During implementation, the centralized component 8 includes a second bin body 81 fixedly mounted on one of the transition bins 4, a second fan 82 fixedly mounted on the second bin body 81, a second detection module 83 fixedly mounted inside the second bin body 81, a socket 84 opened on the outside of the second bin body 81, and a first filter 85 fixedly mounted inside the socket 84. The first detection module 611 and the second detection module 83 have the same structure, and both include a power module, a carbon dioxide detection module, and a remote communication module, so as to supply energy to the carbon dioxide detection module and the remote communication module through the power module, and send the carbon dioxide content data detected by the carbon dioxide detection module to the external controller through the remote communication module. The relevant technologies are all existing mature technologies, so they will not be described in detail here.

[0068] Among them, the connecting component 9 includes a slot 91 opened on another transition bin 4, a convex frame 92 fixed in the slot 91 and a second filter 93 fixed on the outside of the convex frame 92. The second bin body 81, the convex frame 92, the first bin body 31 and the interior of the transition bin 4 are connected. When the two transition bins 4 are fitted together, the second bin body 81 will be plugged and fitted with the slot 91, and the convex frame 92 will be plugged with the second long handle 81 through the socket 84. After the second fan 82 is started, the gas in the two first bin bodies 31 can be discharged to the outside and centrally detected by the second detection module 83. When it is detected that the carbon dioxide concentration exceeds the concentration of normal daily operation, the search vehicle 62 will be started to locate the leakage area.

[0069] Furthermore, in order to facilitate the determination of the leakage area, the positioning component 7 includes a mounting strip 71 fixedly mounted on the transition bin 4 and the sealing side plate 5 and an infrared transmitter 72 fixedly mounted along the length direction of the mounting strip 71. The infrared laser of the infrared transmitter 72 is reflected after contacting the search vehicle 62, so that the infrared transmitter 72 determines the position of the search vehicle 62.
