Description

Technical Field

[0001] This utility model relates to the technical field of liquid storage tank production, and specifically discloses a device for cleaning iron filings from a compressor liquid storage tank. Background Technology

[0002] The compressor receiver-drier is a crucial component of a refrigeration system, primarily used to store refrigerant and simultaneously stabilize refrigerant flow and separate liquid and gaseous components from the refrigerant. During compressor operation, the receiver-drier effectively buffers refrigerant flow fluctuations, ensuring a smooth and uniform flow of refrigerant into the evaporator, thereby improving the system's efficiency and stability. Furthermore, the receiver-drier separates liquid and gaseous components from the refrigerant, preventing liquid refrigerant from entering the compressor, avoiding liquid slugging, and protecting the compressor's safe operation.

[0003] However, during the production of liquid storage tanks, welding and other processes often generate impurities such as iron filings and welding slag on the inner wall. If these impurities are not effectively cleaned, they will enter the refrigeration system with the refrigerant during subsequent use, causing blockages, reduced heat exchange efficiency, and even compressor malfunctions, severely affecting the normal operation and lifespan of the refrigeration system. Existing cleaning methods mostly employ manual or simple mechanical cleaning, but these methods suffer from low cleaning efficiency and incomplete cleaning, making it difficult to meet the quality requirements of large-scale production and unable to effectively eliminate defect rates caused by impurities such as iron filings.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This embodiment discloses a compressor liquid storage tank iron filings cleaning device, referring to... Figure 1-5The system includes a frame 1, on which a brush mechanism 2, an air blowing mechanism 3, and a feeding mechanism 4 are mounted. The brush mechanism 2 includes a brush 21 and a brush drive assembly that drives the brush 21 to move and rotate, effectively brushing the inner wall of the storage tank to remove iron filings. The air blowing mechanism 3 includes an air nozzle 31 and a nozzle drive assembly that drives the air nozzle 31 to move, blowing out the brushed iron filings for further cleaning of the storage tank. A feed hopper 11 is mounted on the frame 1 to store the storage tank containing the iron filings to be cleaned; the end of the feed hopper 11 connects to the feeding mechanism 4. The feeding mechanism 4 includes a feed seat 41 and a feeding drive assembly, which drives the feed seat 41 to move back and forth between the brush mechanism 2 and the air blowing mechanism 3, enabling the orderly transfer of the storage tank between the different cleaning mechanisms and improving cleaning efficiency.

[0028] Specifically, refer to Figure 2-3 The feeding drive assembly includes a transverse drive 42 and a lifting drive 43 mounted on the transverse drive 42. The feeding seat 41 is mounted on the lifting drive 43. The transverse drive 42 can be a transverse cylinder, and the lifting drive 43 can be a lifting cylinder. In addition, a first placement seat 12 is provided on one side of the brush mechanism 2 on the frame 1, and a second placement seat 13 is provided on one side of the air blowing mechanism 3 on the frame 1. Both the first placement seat 12 and the second placement seat 13 are provided with grooves for placing liquid storage tubes. The middle of the first placement seat 12 and the middle of the second placement seat 13 have gaps for the feeding seat 41 to rise upwards and move laterally. The lateral drive 42 can drive the feeding seat 41 to move below the first placement seat 12 or the second placement seat 13, and through the lifting drive 43, the liquid storage tank of the feeding seat 41 can be picked up and placed between the first placement seat 12 and the second placement seat 13. By designing the first placement seat 12 and the second placement seat 13, a stable placement position is provided for the liquid storage tank. In conjunction with the lateral drive 42 and the lifting drive 43, it is ensured that the liquid storage tank can be accurately transferred between the placement seats during the cleaning process, thereby improving the stability and reliability of the cleaning process.

[0029] As a preferred embodiment, the feeding seat 41, the first placement seat 12 and the second placement seat 13 are all provided with grooves for placing multiple liquid storage tanks (three in this embodiment), which can achieve batch cleaning and improve production efficiency.

[0030] As a preferred option, refer to Figure 2The frame 1 is also equipped with a clamping mechanism 5, which includes a frame body disposed on one side of the brush mechanism, a clamping cylinder 51 mounted on the frame body, and multiple clamping blocks 52 (three in this embodiment) assembled on the clamping cylinder 51. The clamping blocks 52 are driven by the clamping cylinder 51 to descend and press the liquid storage tank onto the first placement seat 12. The clamping mechanism 5 can firmly fix the liquid storage tank on the first placement seat 12, and prevent the liquid storage tank from shifting or shaking due to external force when the brush mechanism 2 brushes the liquid storage tank, thus ensuring the uniformity and consistency of the brushing effect and improving the cleaning quality.

[0031] As a preferred option, refer to Figure 4 The brush mechanism 2 includes multiple brushes 21 (three in this embodiment). The brush drive assembly includes a brush cylinder 22. A brush mounting base 23 is provided on the output end of the brush cylinder 22. Multiple connecting columns are rotatably connected to the brush mounting base 23 via bearings. Each brush 21 is mounted on a connecting column. Each brush 21 corresponds to a groove in the first placement seat 12. The brush mounting base 23 is provided with a drive gear 25 and a driven gear 26. The drive gear 25 and the driven gear 26 are respectively assembled on each connecting column. The brush motor drives the drive gear 25 to rotate. The drive gear 25 and the driven gear 26 are driven by a meshing chain. By adopting the above scheme, the brush cylinder 22 can drive the brush 21 to move axially and extend into the liquid storage tank to contact the inner wall of the liquid storage tank. The brush motor 24 drives the brush 21 to rotate, so that the brush 21 can brush the inner wall of the liquid storage tank at an appropriate speed and force. The effective combination of the movement and rotation functions of the brush 21 improves the efficiency and effect of brushing and better completes the cleaning of iron filings in the liquid storage tank. In addition, through the cooperation of the brush motor 24 with the drive gear 25 and the driven gear 26, multiple brushes can be driven to rotate and wash simultaneously, improving the brushing efficiency.

[0032] As a preferred option, refer to Figure 5 The air blowing mechanism 3 includes multiple air blowing nozzles 31 (three in this embodiment). The nozzle driving assembly includes a nozzle cylinder 32 and a nozzle mounting seat 33 installed at the output end of the nozzle cylinder 32. The multiple air blowing nozzles 31 are installed on the nozzle mounting seat 33, and each air blowing nozzle 31 corresponds one-to-one with each groove of the second placement seat 13. By adopting the above scheme, the nozzle cylinder 32 can drive the air blowing nozzles 31 to move axially and extend into the liquid storage tank. The depth position of the air blowing nozzles 31 can be adjusted, which improves the air blowing cleaning effect and further ensures the cleanliness of the iron filings in the liquid storage tank.

[0033] As a preferred embodiment, the second placement seat 13 is inclined toward the side of the air nozzle 31, so that when the liquid storage tank is placed on the second placement seat 13, the opening end of the liquid storage tank is tilted downwards, which can better allow the blown iron filings to fall from the liquid storage tank and further improve the cleaning efficiency.

[0034] The working process of this scheme is as follows: The transverse drive 42 starts from the position of the feed hopper 11, and the lifting drive 43 rises to lift the liquid storage tank in the feed hopper 11, thereby realizing the material from the liquid storage tank in the feed hopper 11 into the feeding seat 41; then, the transverse drive 42 drives the feeding seat 41 to move to the brush mechanism 2 position, the lifting drive 43 descends, thereby placing the liquid storage tank on the first placement seat 12, the clamping cylinder 51 is activated to clamp the liquid storage tank, the brush cylinder 22 is activated, and after sensing that the brush has reached the designated position, the brush motor 24 is activated to start brushing the iron filings on the inner wall of the liquid storage tank; after the brush has finished cleaning the iron filings, the lifting drive 43 rises to lift the liquid storage tank on the first placement seat 12 and moves it to the air blowing mechanism 3 position through the transverse drive 42, the lifting drive 43 descends, thereby placing the liquid storage tank on the second placement seat 13, the nozzle cylinder 32 is activated, and after reaching the designated position, it starts blowing the air to clean the inner wall of the liquid storage tank. This solution uses a combination of a brush mechanism 2 and an air blowing mechanism 3 to first clean the inner wall of the storage tank, eliminating welding slag adhering to the weld seam. Then, high-pressure gas is used to clean the inside of the storage tank to remove iron filings that were brushed off but did not fall out. The combination of brush and air blowing effectively improves the iron filings cleaning effect of the storage tank and significantly reduces the defect rate caused by foreign objects.

[0035] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
