Description

Technical Field

[0001] The utility model relates to the technical field of pearl sand filling systems, and in particular to a pearl sand filling system. Background Art

[0002] When pearl sand is filled into the interlayer space, it is in a loose state. Due to the different particle sizes, small mass, and the angle of repose of the particles, it cannot be compacted by its own weight in a short period of time, resulting in gaps between the pearl sand particles, which affects the insulation performance of the cryogenic storage tank.

[0003] Currently, pearlescent sand filling often uses a magnetic hammer or vibrating pump to vibrate the sand, smoothing its angle of repose, reducing or eliminating gaps between particles, and improving the thermal insulation performance of cryogenic storage tanks. However, vibration often causes a degree of irreversible damage to equipment. Incorporating this vibration into the design process undoubtedly increases design and manufacturing costs.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content

[0005] This utility model proposes a pearl sand filling system, which solves the problem that vibration in related technologies often causes a certain degree of irreversible damage to equipment.

[0031] Positioning lifting assembly 6, between the base plate 1 and the bracket 2;

[0032] The buffer assembly 5 includes a pearl sand filling device 5-1, which is arranged on the bracket 2, and a vacuum pumping device 5-2 is provided on the bracket 2. The output end of the vacuum pumping device 5-2 is provided with a negative pressure pipe 5-3, and the lower end of the pearl sand filling device 5-1 is provided with a three-way pipe 5-4. A pair of brackets 5-5 are provided at the bottom of the bracket 2, and a nitrogen tank 5-6 is installed on the bracket 5-5. The air outlet end of the nitrogen tank 5-6 is plug-connected with one end of the three-way pipe 5-4. A telescopic cylinder 5-7 is provided at the bottom of the bracket 5-5, and a pressure plate 5-8 is provided at the output end of the telescopic cylinder 5-7. A negative pressure nozzle 5-9 and a sand inlet nozzle 5-10 are respectively provided on the top of the low-temperature container 4. The negative pressure nozzle 5-9 is plug-connected with the negative pressure pipe 5-3, and the sand inlet nozzle 5-10 is plug-connected with the lower end of the three-way pipe 5-4.

[0033] In this embodiment, the pearl sand filling device 5 - 1 , the vacuum device 5 - 2 and the pearl sand storage tank 3 cooperate with each other to fill the low-temperature container 4 with pearl sand, which can reduce vibration during the filling process.

[0034] Furthermore, the positioning and lifting assembly 6 includes a fixed plate 6-1, which is fixed on the bracket 2. A pair of second cylinders 6-2 are provided on the surface of the fixed plate 6-1, and a lifting base 6-3 is provided at the output end of the second cylinder 6-2. The lifting base 6-3 is supported on the bottom of the low-temperature container 4.

[0036] Furthermore, an air inlet 7 is provided on the top of the pearl sand storage tank 3 , and a filter element 8 is inserted into the air inlet 7 .

[0037] In this embodiment, an air inlet 7 and a filter element 8 are provided to ensure air intake into the pearl sand storage tank 3 and prevent foreign matter from entering.

[0038] Furthermore, one side of the bracket 5 - 5 is a semicircular structure and matches the diameter of the low-temperature container 4 .

[0039] In this embodiment, the low-temperature container 4 can be automatically adjusted after being placed in the lifting base 6 - 3 through the matching size effect.

After the nitrogen impact, the filling action is repeated until all pearl sand openings stop feeding sand. Each pearl sand opening is nitrogen compacted at least twice. During the whole process, the vacuum device 5-2 always keeps working.
