Description

Technical Field

[0001] The utility model belongs to the technical field of gas recovery, in particular to a steel cylinder refrigeration device for recovering krypton-xenon gas. Background Art

[0002] Krypton-xenon has extremely high luminous intensity and strong fog-penetrating ability, and is widely used in electronics, power sources, gas lasers, plasma flows, atomic reactors, and high-energy physics. Generally, krypton-xenon is prepared by air separation and then packed into seamless steel cylinders for storage, transportation, and use. The low-temperature freezing device uses the principle of low-temperature freezing to extract the krypton-xenon gas in the cylinder through a vacuum pump and introduce it into a freezing bottle for freezing and solidification.

[0003] Subsequently, by reheating the frozen bottle, the solidified krypton-xenon gas is released and filled into the gas recovery bottle, thereby realizing the recycling and reuse of krypton-xenon. The existing low-temperature freezing device for recovering residual krypton-xenon in steel cylinders requires staff to manually adjust the distance between the two sets of clamping plates when clamping and fixing the cylinders. When adjusting the distance of the clamping plates, the refrigerant on the surface of the cylinder can easily be accidentally touched by the staff, causing harm to the staff. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a steel cylinder refrigeration device for recovering krypton and xenon gases, which solves the problem that in the existing low-temperature refrigeration device for recovering residual krypton and xenon in steel cylinders, the staff needs to manually adjust the distance between the two sets of clamping plates when clamping and fixing the steel cylinder. When adjusting the distance of the clamping plates, the refrigerant on the surface of the steel cylinder is easily accidentally touched by the staff, thereby causing harm to the staff.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A cylinder refrigeration device for recovering krypton and xenon gas, comprising a main body, a servo motor fixedly connected to the main body, an output end of the servo motor fixedly connected to a bevel gear, a connecting gear engaged with one side of the bevel gear, a threaded rod fixedly connected to the top of the connecting gear, a moving block slidably connected to the external thread of the threaded rod, a rotating motor fixedly connected to the moving block, the output end of the rotating motor is connected to a rotating ring via a rotating shaft, the top of the rotating ring is connected to a pulling rod via a rotating shaft, one end of the pulling rod is connected to a snap-on sliding block via a rotating shaft, and the top of the snap-on sliding block is fixedly connected to a fixed block.

[0006] As a further solution of the present invention: a sliding groove is provided in the fixed block, and the bottom end of the rotating ring is rotatably connected to the fixed ring.

[0007] As a further solution of the present invention: four slide blocks are fixedly connected to the outer arc surface of the fixed ring, and the bottom of the clamping sliding block is slidably connected to the slide block.

[0008] As a further solution of the present invention: two clamping springs are fixedly connected to the inner wall of the sliding groove, one end of the two clamping springs is fixedly connected to a clamping block, and the top end of the rotating ring is rotatably connected to a placement bottom block.

[0009] As a further solution of the present invention: the external thread of the threaded rod is slidably connected to a slider, and one side of the slider is fixedly connected to a limiting block.

[0010] As a further solution of the present invention: sliding clamping blocks are slidably connected to both sides of the limit block, and one side of the two sliding clamping blocks is fixedly connected to the same bidirectional electric push rod.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The krypton-xenon gas recovery cylinder refrigeration device is provided with a placement base block, a rotating motor, a rotating ring, and a clamping sliding block. When the cylinder is placed on the placement base block, the rotation of the output end of the rotating motor can drive the rotating ring to rotate synchronously. The rotating ring drives the pull rod to rotate and pull synchronously through rotation. At this time, the pull rod can be used to pull the clamping sliding block to slide, so that the four clamping sliding blocks move simultaneously. When the clamping sliding block moves, it drives the top fixed block to move on the slide block, clamping and fixing the cylinder placed on the placement base block, reducing the manual control of the clamping and fixing operation by the staff, and preventing the refrigerant on the outer surface of the cylinder from causing harm to the staff.

[0013] 2. The krypton-xenon gas recovery cylinder refrigeration device is provided with a servo motor, a bevel gear, and a linkage gear. The rotation of the servo motor synchronously drives the bevel gear to rotate. When the bevel gear rotates, it can synchronously drive the meshing linkage gear to rotate. When the linkage gear rotates, it synchronously drives the threaded rod fixed on the linkage gear to rotate. When the threaded rod rotates, the moving block and the slider slidably connected to the threaded rod move, which facilitates the lifting of the cylinder body and makes it convenient for the staff to pick up and place the cylinder, so that the cylinder can better meet the needs of different heights.
