Description

Technical Field

[0002] At present, the liquid storage body of a conventional rotary compressor is installed on one side of the compressor body. The rotation of the rotating components of the compressor will cause the vibration of the liquid storage body. The vibration of the upper part of the liquid storage body is usually improved by fixing the liquid storage bracket.

[0050] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0051] As Figure 1 and Figure 2 shown, Embodiment 1 of the present utility model provides a liquid storage tank, which includes a liquid storage tank body 1, an outlet pipe 10 and an outer tube 20. The outlet pipe 10 is connected to the liquid storage tank body 1; the outer tube 20 is sleeved on the outlet pipe 10, and a filling cavity is formed between the outlet pipe 10 and the outer tube 20. The liquid storage tank further includes a partition assembly 30, and the partition assembly 30 is fixedly arranged in the filling cavity. The partition assembly 30 includes a plurality of partition boards 31, and the plurality of partition boards 31 divide the filling cavity into a plurality of sealed cavities 40. The liquid storage tank further includes a plurality of damping particles 50, and at least one damping particle 50 is arranged in each sealed cavity 40.

[0052] By using the liquid storage tank provided in Embodiment 1 of the present utility model, through the arrangement of the partition assembly 30, the sealed cavity 40 and the damping particles 50, the vibration at the outlet pipe 10 of the liquid storage tank can be transmitted to the plurality of damping particles 50, and the energy on the vibration transmission path of the outlet pipe 10 can be consumed by the elastic collision between the plurality of damping particles 50 and the collision between the damping particles 50 and the partition board 31, thereby reducing the vibration amplitude at the outlet pipe 10 of the liquid storage tank. Therefore, through the liquid storage tank provided in this embodiment, the technical problem of poor vibration reduction effect of the pipeline vibration reduction measures in the prior art can be solved.

[0053] Specifically, in order to facilitate the connection between the liquid storage device and other devices, the air outlet pipe 10 is an air outlet elbow.

[0054] Specifically, the plurality of partitions 31 divide the filling cavity into a plurality of transverse cavity groups along the extension direction of the air outlet pipe 10, and each transverse cavity group includes a plurality of closed cavities 40 surrounding the air outlet pipe 10. With such a structural arrangement, the damping particles 50 in the filling cavity can be prevented from accumulating at a local position of the filling cavity under the influence of gravity through the arrangement of the transverse cavity groups, thereby avoiding affecting the vibration reduction effect on the air outlet pipe 10. In addition, the arrangement of the closed cavities 40 surrounding the air outlet pipe 10 can cause the damping particles 50 to be scattered at different positions around the air outlet pipe 10, thereby further ensuring the vibration reduction effect on the air outlet pipe 10.

[0055] Specifically, the closed cavity 40 is polygonal or circular. With such a structural arrangement, the wall area in contact with the damping particles 50 can be increased, thereby further enhancing the vibration reduction effect.

[0056] Specifically, the damping particles 50 are spherical in structure. With such a structural arrangement, the damping particles 50 can be easily rolled and collided in the closed cavity 40, thereby further enhancing the vibration reduction effect.

[0057] Specifically, the plurality of partitions 31 include a longitudinal partition 311 and a transverse partition 312. The longitudinal partition 311 is extended along the axial direction of the outer tube 20, one side of the longitudinal partition 311 is connected to the outer wall of the outlet pipe 10, and the other side of the longitudinal partition 311 is connected to the inner wall of the outer tube 20. The transverse partition 312 is extended along the radial direction of the outer tube 20, and is a ring-shaped member, the inner ring of the transverse partition 312 is connected to the outer wall of the outlet pipe 10, and the outer ring of the transverse partition 312 is connected to the inner wall of the outer tube 20. There are at least two longitudinal partitions 311 and transverse partitions 312, and at least two longitudinal partitions 311 and at least two transverse partitions 312 are staggered to enclose a closed cavity 40. By adopting such a structural setting, the damping particles 50 can be distributed more evenly in the filling cavity through the staggered setting of the longitudinal partitions 311 and the transverse partitions 312, and will not accumulate at a certain position due to the influence of gravity. Such a setting can better ensure the vibration reduction effect at various locations of the air outlet pipe 10 and avoid local failure of the vibration reduction effect.

[0058] like Figure 3 and Figure 4As shown in the figure, in the second embodiment of the present utility model, a plurality of partition plates 31 are connected to each other to form a honeycomb structure. One side of the honeycomb structure is connected to the outer wall of the air outlet pipe 10, and the other side of the honeycomb structure is connected to the inner wall of the outer pipe 20. A plurality of sealed cavities 40 are formed between the honeycomb structure, the outer wall of the air outlet pipe 10, and the inner wall of the outer pipe 20. With such a structural arrangement, the wall area that can come into contact with the damping particles 50 can be increased through the honeycomb structure, thereby further enhancing the vibration damping effect.

[0059] Specifically, the sealed cavities 40 are arranged to be size-matched with the damping particles 50, and the plurality of sealed cavities 40 are arranged in one-to-one correspondence with the plurality of damping particles 50. With such a structural arrangement, the collision effect between the damping particles 50 and the partition plates 31 can be ensured by filling a single damping particle 50 in the size-matched sealed cavities 40, thereby increasing the speed of vibration transmission and enhancing the efficiency of consuming the energy of vibration transmission, and further enhancing the vibration damping effect.

[0060] Specifically, in order to further increase the collision and friction between the damping particles 50, at least two damping particles 50 are arranged in each of the sealed cavities 40.

[0061] As Figure 5 and Figure 6 shown in the figure, in the third embodiment of the present utility model, the partition component 30 further includes a sleeve 32. The sleeve 32 is sleeved on at least part of the outer wall of the air outlet pipe 10 and is in mutual contact with at least part of the outer wall of the air outlet pipe 10. A filling cavity is formed between the outer pipe 20 and the sleeve 32, and the sleeve 32 is connected to the outer pipe 20 through the partition plate 31. With such a structural arrangement, through the arrangement of the sleeve 32, the sleeve 32, the partition plate 31, and the outer pipe 20 can form a vibration damping component independent of the air outlet pipe 10, thereby facilitating the maintenance, disassembly, and assembly of the vibration damping component, simplifying the assembly steps, and improving the use efficiency.

[0062] Specifically, the sleeve 32 is detachably arranged on the air outlet pipe 10. With such a structural arrangement, when it is necessary to adjust the partition plate 31, the damping particles 50, or the outer pipe 20, the sleeve 32 can be removed from the air outlet pipe 10 without affecting the normal operation of the air outlet pipe 10 in the liquid storage container and without interfering with other structural parts of the liquid storage container.

[0063] Specifically, for the convenience of installation, the sleeve 32 and the air outlet pipe 10 are arranged in a hot-sleeved fit.

[0064] Specifically, the sleeve 32 is movably arranged on the air outlet pipe 10. With such a structural arrangement, for the different vibration amplitude distributions of the air outlet pipe 10 in different situations, the sleeve 32 can be moved to the position with a larger vibration amplitude according to the need, thereby further improving the vibration damping effect and optimizing the vibration damping efficiency.

[0065] As Figure 7 shown, in the fourth embodiment of the present utility model, the damping particles 50 include a wrapping member 51 and a plurality of particulate dispersoids 52. The wrapping member 51 encloses an inner cavity, and the plurality of particulate dispersoids 52 are located inside the inner cavity. With such a structural arrangement, the vibration damping effect of the damping particles 50 can be further enhanced by the setting of the wrapping member 51 and the plurality of particulate dispersoids 52.

[0066] Specifically, in order to enhance the buffering effect of the collision damping between the damping particles 50, the wrapping member 51 is made of a soft material. Specifically, the wrapping member 51 is made of a polymer material.

[0067] Specifically, in order to improve the vibration damping performance of the damping particles 50, the particulate dispersoids 52 are particles made of metal damping particles or polymer material particles or a hybrid material formed by metal materials and polymer materials. Specifically, the average diameter of the particulate dispersoids 52 is less than 3 mm.

[0068] In the first, second, third, and fourth embodiments, the damping particles 50 are non-blocking particulate dampers. Specifically, the damping particles 50 can be at least one of iron-based particles, tungsten-based particles, copper particles, lead particles, and ceramic particles. Specifically, the outer surface of the damping particles 50 is roughened.

[0069] In the first, second, third, and fourth embodiments, in order to enhance the elastic collision performance of the damping particles 50, the damping particles 50 are flexible particulate dampers.

[0070] In the first, second, third, and fourth embodiments, the damping particles 50 are in a powdery structure, and the average particle size of the damping particles 50 is greater than 0 mm and less than or equal to 1 mm. Specifically, the damping particles 50 are steel powder or tungsten powder.

[0071] In the first, second, third, and fourth embodiments, the damping particles 50 are in a granular structure, and the average particle size of the damping particles 50 is greater than or equal to 0.2 mm and less than or equal to 2 mm.

[0072] Specifically, the number of the damping particles 50 is positively correlated with the magnitude of the vibration amplitude of the air outlet pipe 10 corresponding to the position where the damping particles 50 are located. The surface roughness of the damping particles 50 is positively correlated with the magnitude of the vibration amplitude of the air outlet pipe 10 corresponding to the position where the damping particles 50 are located. With such a structural arrangement, the damping particles 50 can be selectively filled according to the different vibration amplitudes of different parts of the air outlet pipe 10, and the damping particles 50 with a rougher surface or a larger number are filled in the sealed cavity 40 near the position with a larger vibration, so as to further improve the vibration damping effect.

[0073] As Figure 8As shown in the figure, Embodiment 5 of the present utility model provides a compressor, which includes a liquid receiver and a compressor body 2 of any one of Embodiments 1, 2, 3, and 4. A connection port 201 is provided on the compressor body 2, and the outlet pipe 10 of the liquid receiver is connected to the connection port 201.

[0074] By using the compressor provided in Embodiment 5 of the present utility model, through the arrangement of the partition component 30, the sealed cavity 40, and the damping particles 50, the vibration at the outlet pipe 10 of the liquid receiver can be transmitted to a plurality of damping particles 50. The elastic collision between the plurality of damping particles 50 and the collision between the damping particles 50 and the partition 31 are utilized to consume the energy on the vibration transmission path of the outlet pipe 10, thereby reducing the vibration amplitude at the outlet pipe 10 of the liquid receiver. Therefore, through the compressor provided in this embodiment, the technical problem of poor vibration reduction effect of the pipeline vibration reduction measures in the prior art can be solved.

[0075] Specifically, the compressor further includes a shell tube 202, which is installed at the connection port 201. One end of the shell tube 202 is connected to the compressor body 2, and the other end of the shell tube 202 extends out of the compressor body 2. One end of the outlet pipe 10 is inserted into the shell tube 202 and connected to the connection port 201. Among them, the shell tube 202 and the outer tube 20 of the liquid receiver are of an integrally formed structure. With such a structural arrangement, the sealing performance between the outer tube 20 and the shell tube 202 can be enhanced, thereby better ensuring the normal operation of the compressor.

[0076] Specifically, the compressor further includes a shell tube 202, which is installed at the connection port 201. One end of the shell tube 202 is connected to the compressor body 2, and the other end of the shell tube 202 extends out of the compressor body 2. One end of the outlet pipe 10 is inserted into the shell tube 202 and connected to the connection port 201. Among them, the other end of the shell tube 202 is connected to the outer tube 20 of the liquid receiver. Specifically, the other end of the shell tube 202 is welded to the outer tube 20 of the liquid receiver. With such a structural arrangement, it is convenient to independently process the liquid receiver, thereby enabling the assembly of the compressor to be more flexible.

[0077] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: By arranging the particle damping vibration absorption device outside the elbow connecting the compressor pump body and the liquid receiver, the elastic collision between multiple particle dampings is utilized to consume the energy on the vibration transmission path between the compressor pump body and the liquid receiver, thereby reducing the vibration amplitude of the liquid receiver.
