Description

Technical Field

[0001] This utility model relates to the field of filtration technology, specifically to a compressor oil circuit iron powder collection device. Background Technology

[0002] Currently, most compressors use a combination of filters and filter elements for oil purification. The cleanliness of the oil directly affects the wear of critical moving parts in the compressor, such as the crankshaft, main bearings, bushings, crosshead slides, piston rods, and packing, impacting their lifespan. Replacing even one moving part can be extremely costly for compressor users; frequent oil and filter changes also incur significant expenses.

[0003] To improve the filtration quality of oil filters, filters with higher filtration precision can be used; however, these filters still have the following problems in actual use:

[0004] 1. The filtration accuracy is directly linked to the price of the filter; the higher the accuracy, the more the price increases, resulting in excessively high costs.

[0005] 2. Oil filters with higher filtration precision are also more prone to clogging and have low flow rates. Utility Model Content

[0006] The purpose of this invention is to provide a compressor oil circuit iron powder collection device to solve the problems of high cost and easy clogging of existing high-precision filters.

[0007] To achieve the above-mentioned utility model objectives, the technical solution adopted by this utility model is as follows: This utility model provides a compressor oil circuit iron powder collection device, the device comprising: a box body, an oil outlet on one side of the box body, at least one of the remaining sides of the box body having a mesh structure, and a magnet for collecting iron powder being provided inside the box body.

[0008] Preferably, the box body has an opening on one side, and a cover plate is detachably connected to the opening. The cover plate serves as one side of the box body, and the oil outlet is located in the middle of the cover plate.

[0009] Preferably, a connecting plate is provided on the inner side of the cover plate, a through hole is provided in the middle of the connecting plate, and a filter screen is provided between the connecting plate and the cover plate.

[0010] Preferably, the magnet has a ring structure, the cover plate is provided with a magnetic attraction part, the magnet and the magnetic attraction part on the cover plate form a magnetic attraction engagement, and the connecting plate is pressed onto the cover plate by the magnetic attraction engagement between the magnet and the magnetic attraction part.

[0011] Preferably, the magnet is a neodymium magnet.

[0012] Preferably, it also includes a pair of clamping plates, each clamping plate having a through groove along its length. The two clamping plates are installed on the inner side wall of the compressor body's main oil outlet, and the two through grooves are arranged opposite each other to form a guide area, which is used to insert the cover plate.

[0013] Preferably, a limiting part is provided on one side of the cover plate. After the cover plate is inserted into the guide area, the limiting part abuts against the top of the card plate, and the oil outlet on the cover plate is connected to the main oil outlet of the compressor body.

[0014] Preferably, a filter is connected to the outside of the compressor body's main oil outlet. The filter includes a filter body and a connector, and the filter body is connected to the compressor body's main oil outlet via the connector.

[0015] Preferably, the filter body is a Y-type filter.

[0016] The beneficial effects of this utility model are mainly reflected in:

[0017] 1. The box body of this utility model has a mesh structure on the side, so the mesh structure can filter out coarse impurities in the oil. Then, the strong magnetic attraction of the magnet is used to adsorb and capture iron filings, iron powder, iron dust and other particles of various sizes deposited in the oil passage, preventing smaller particles from entering the subsequent oil passage. This can improve the cleanliness of the oil during the compressor break-in period. The device has a simple structure, low cost and good filtration effect.

[0018] 2. This utility model can significantly improve the oil filtration effect, reduce the frequency of oil changes, and extend the replacement cycle of the oil filter, saving operating costs for equipment users; secondly, because the oil is cleaner, it can significantly reduce the wear of important moving parts, extend their service life, and save on spare parts and maintenance costs.

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0024] Example 1

[0025] Figure 1 This is an exploded view of the overall structure of a compressor oil circuit iron powder collection device according to one embodiment of this utility model. Figure 1 As shown, this embodiment provides a compressor oil circuit iron powder collection device. The device includes: a box body 1, an oil outlet 5 on one side of the box body 1, at least one of the remaining sides of the box body 1 having a mesh structure, and a magnet 2 for collecting iron powder inside the box body 1.

[0026] In this embodiment, the box 1 is a square box with a total of six sides, one of which is provided with an oil outlet 5, and the other five sides are mesh structures; the box 1 can also be other shapes, such as tubular, and can be flexibly selected according to actual needs.

[0027] In this embodiment, one side of the housing 1 can be installed inside the main oil outlet 12 of the compressor body. The oil outlet 5 on the housing 1 is connected to the main oil outlet 12 of the compressor body. At this time, the oil flows into the main oil outlet 12 of the compressor body through the housing 1. Since the side of the housing 1 is a mesh structure, the housing 1 itself can filter some of the larger impurities. However, the housing 1 itself cannot filter smaller impurities such as iron filings, iron powder, and iron dust. After these impurities enter the housing 1, the housing 1 is equipped with a magnet 2, which is a neodymium magnet. The neodymium magnet can generate a strong magnetic attraction force, which can adsorb and capture smaller impurities such as iron filings, iron powder, and iron dust, preventing smaller impurities from entering the subsequent oil circuit. This can improve the cleanliness of the oil during the compressor break-in period. This device has a simple structure, low cost, and good filtration effect.

[0028] Example 2

[0029] Based on Embodiment 1, the box body 1 of this embodiment adopts a split structure, that is, an opening 3 is provided on one side of the box body 1, and a cover plate 4 is detachably connected to the opening 3. The cover plate 4 serves as one side of the box body 1, and the oil outlet 5 is located in the middle of the cover plate 4.

[0030] In this embodiment, the cover plate 4 can be installed on the opening 3 of the box body 1 with screws. The magnet 2 is placed directly on the box body 1. When it is necessary to clean the impurities captured on the magnet 2 inside the box body 1, the box body 1 can be taken out from the compressor body, and then the cover plate 4 can be removed to take out the magnet 2 for cleaning. The box body 1 adopts a split structure, which has better cleaning convenience and practicality.

[0031] Example 3

[0032] Based on Embodiment 2, this embodiment also deploys a two-stage filtration structure, namely, a connecting plate 6 is provided on the inner side of the cover plate 4, a through hole 7 is provided in the middle of the connecting plate 6, and a filter screen plate 8 is provided between the connecting plate 6 and the cover plate 4.

[0033] In this embodiment, the filter screen 8 is a two-stage filtration structure. Since there may be small particulate impurities in the oil that cannot be attracted by the magnet 2, these impurities can be filtered by the filter screen 8 to further improve the cleanliness of the oil during the compressor break-in period.

[0034] Example 4

[0035] Based on Embodiment 3, since the magnet 2 is placed directly inside the housing 1, when the oil flow rate is high, particulate matter is flushed into the secondary filtration structure before it can be captured. However, the secondary filtration structure cannot filter out these smaller particulate impurities. Therefore, to avoid the above situation, the magnet 2 is a ring structure, and a magnetic attraction part is provided on the cover plate 4 (the cover plate 4 can be made of iron, or an iron ring can be embedded in the cover plate 4, and the magnet 2 can be attracted to the cover plate 4). The magnet 2 and the magnetic attraction part on the cover plate 4 form a magnetic attraction fit, and the connecting plate 6 is pressed tightly onto the cover plate 4 through the magnetic attraction fit between the magnet 2 and the magnetic attraction part.

[0036] In this embodiment, after the magnet 2 attracts the oil, it presses the connecting plate 6 onto the cover plate 4. Simultaneously, the filter screen 8 is also pressed between the connecting plate 6 and the cover plate 4. The magnet 2, the oil outlet 5 on the cover plate 4, and the through hole 7 on the connecting plate 6 are coaxially aligned. At this time, the oil flowing into the secondary filtration structure passes through the center of the magnet 2, where the magnetic force is strongest, effectively capturing smaller impurities.

[0037] Example 5

[0038] Based on Embodiment 4, the device further includes a pair of clamping plates 9, each clamping plate 9 having a through groove 10 along its length. After the two clamping plates 9 are installed on the inner side wall of the compressor body's main oil outlet 12, the two through grooves 10 are arranged opposite each other to form a guide area, which is used to insert the cover plate 4.

[0039] In this embodiment, the two clamping plates 9 can be installed on the inner side wall of the compressor body's main oil outlet 12 using screws, such as... Figure 2 As shown; the length of the guide area is adapted to the length of the cover plate 4, and the width of the guide area is adapted to the thickness of the cover plate 4; secondly, when the cover plate 4 is inserted into the guide area, it can form an interference fit with the guide area, which can seal the inner wall between the cover plate 4 and the compressor body's main oil outlet 12, preventing oil from flowing from between the cover plate 4 and the inner wall of the compressor body's main oil outlet 12 into the compressor body's main oil outlet 12, and ensuring that the oil discharged from the compressor body's main oil outlet 12 has a high degree of cleanliness.

[0040] In this embodiment, when the cover plate 4 and the guide area form an interference fit, the cover plate 4 usually will not slip off from the guide area; however, this makes it inconvenient to remove the box 1 from the guide area. Therefore, in order to solve this technical problem, this embodiment provides a limiting part 11 on one side of the cover plate 4. At this time, the cover plate 4 has an L-shaped structure. After the cover plate 4 is inserted into the guide area, the limiting part 11 abuts against the top of the retaining plate 9, and the oil outlet 5 on the cover plate 4 is connected to the main oil outlet 12 of the compressor body.

[0041] Example 6

[0042] Based on Embodiment 5, a filter is connected to the outside of the compressor body's main oil outlet 12. The filter includes a filter body 13 and a connector 14. The filter body 13 is connected to the compressor body's main oil outlet 12 through the connector 14. The filter body 13 is a Y-type filter, i.e., an oil filter.

[0043] In this embodiment, the compressor oil circuit iron powder collection device is used in conjunction with an oil filter, which can significantly improve the oil filtration effect, reduce the frequency of oil changes, and extend the replacement cycle of the oil filter. This saves operating costs for the equipment user. Because the oil is cleaner, wear on important moving parts can be significantly reduced, extending their service life and saving on spare parts and maintenance costs. Due to reduced wear, the unit vibration will not increase, the noise will not rise, the piston rod runout will be smaller, and the service life of the packing will also be improved.

[0044] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
