Description
Technical Field
[0001] This utility model relates to the field of air compressor filter technology, and in particular to an air compressor filter with adjustable filter pore size. Background Technology
[0002] Air compressor filter elements are the core filtration components of the air compressor intake system. Installed at the front end of the air compressor intake port, their function is to filter dust, sand, lint, and some moisture in the intake air, preventing impurities from entering the compressor. By intercepting contaminants, they can prevent damage to the rotor, cylinder, and bearings due to wear and scratches, reducing equipment failures. At the same time, they can ensure the cleanliness of the intake air, indirectly improving the quality of compressed air.
[0003] Air compressor filters can efficiently filter dust and grit from the air with a high interception rate, effectively protecting the compressor rotor and bearings and reducing wear and the risk of failure. Secondly, they can maintain a stable air intake, ensuring that the air compressor's operating efficiency does not decrease. They can also extend the service life of the equipment and reduce maintenance and replacement costs. At the same time, they can indirectly improve the quality of compressed air and prevent downstream air-using equipment from being contaminated.
[0004] In complex environments where the dust content in the air increases sharply, fixed apertures cannot enhance filtration, leading to impurities penetrating and exacerbating component wear. In clean environments, fixed apertures may increase air intake resistance due to excessively high filtration precision, resulting in increased energy consumption and decreased gas production efficiency. This fixed design is difficult to adapt to changing operating conditions, and may lead to insufficient or excessive filtration, increasing maintenance frequency and equipment wear risk.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: an air compressor filter element with adjustable filter pore diameter, including a top cover 1 and a base 2. The bottom of the top cover 1 is provided with an adjustable outer core mechanism 3, which is used to adjust the filter pore diameter of the outer core. The top of the base 2 is provided with a detachable inner core mechanism 4, which is used to quickly remove the inner core for easy cleaning or replacement. An operating box mechanism 5 is provided between the adjacent parts of the top cover 1 and the base 2.
[0034] The adjustable outer core mechanism 3 includes a rotating column 31, the top of which is located at the bottom of the top cover 1. A pressure plate 32 is fixedly connected to the bottom of the rotating column 31. A connecting plate 33 is fixedly connected to the outer wall of the pressure plate 32. An outer core 1 34 is fixedly connected to the bottom end of the connecting plate 33. An outer core 2 35 is slidably connected to the outer wall of the outer core 1 34. A bearing assembly 36 is provided at the bottom of the rotating column 31. An elastic assembly 37 is provided at the bottom of the pressure plate 32. A rotating assembly 38 is provided at the top end of the outer core 2 35.
[0035] Specifically, the top of the rotating column 31 is located at the bottom of the top cover 1. The pressure plate 32 fixedly connected to its bottom rotates synchronously with the rotation of the rotating column 31. The connecting plate 33 fixed to the outer wall of the pressure plate 32 drives the outer core 34 to rotate accordingly. The outer core 34 rotates relative to the outer wall of the outer core 35. The top of the outer core 35 is provided with a rotating component 38, which provides guidance for the relative rotation between the outer core 34 and the outer core 35 when the connecting plate 33 drives the outer core 34 to rotate, so that the rotation trajectory of the two is stable. The bearing component 36 at the bottom of the rotating column 31 reduces the frictional resistance during the rotation of the rotating column 31 and ensures the smoothness of the rotation of the rotating column 31. At the same time, the elastic component 37 at the bottom of the pressure plate 32 applies a limiting effect to the rotating component 38. By limiting the displacement of the rotating component 38, the outer core 34 will not rotate arbitrarily.
[0036] Both outer core 1 34 and outer core 2 35 are provided with filter holes. By rotating the two relative to each other, the size of the overlapping area of the filter holes is changed, thereby realizing the adjustment of the filter hole diameter of the outer core. The detachable inner core mechanism 4 is located inside the adjustable outer core mechanism 3. Based on the preliminary filtration achieved by the adjustable outer core mechanism 3, the filtration accuracy is further improved, so that the air filtered by the filter element meets the usage requirements. The operating box mechanism 5 is located between the top cover 1 and the base 2, providing stable support and protection for the operation of the entire filter element, and ensuring the coordination and reliability of each mechanism during operation.
[0037] Reference Figure 3 and Figure 5 The detachable inner core mechanism 4 includes a chassis 41, the bottom of which is located on the top of the base 2. An inner filter element 42 is fixedly connected to the top of the chassis 41, and a top plate 43 is fixedly connected to the top of the inner filter element 42. A connecting column 44 is provided inside the bearing assembly 36. The bottom of the outer core 2 35 is fixedly connected to the base plate 45, and the bottom of the outer core 1 34 is slidably connected to the top of the base plate 45. A sliding groove assembly 46 is provided on the inner wall of the chassis 41, and a sliding opening 47 is provided at the bottom of the chassis 41.
[0038] Specifically, an inner filter element 42 is fixedly connected to the top of the chassis 41, and a top plate 43 is fixedly connected to the top of the inner filter element 42. The fixing action between the chassis 41 and the top plate 43 ensures that the inner filter element 42 is in a stable installation state. A connecting column 44 is provided inside the bearing assembly 36. The connecting column 44 provides a structural connection for the operation of the bearing assembly 36. A base plate 45 is fixedly connected to the bottom of the outer core 2 35. The base plate 45 fixes the bottom of the outer core 2 35. The bottom of the outer core 1 34 is slidably connected to the top of the base plate 45, so that the outer core 1 34 can rotate stably on the base plate 45. A sliding groove assembly 46 is provided on the inner wall of the chassis 41. The sliding groove assembly 46 provides a path for the movement of the components.
[0039] The bottom of the chassis 41 is provided with a sliding opening 47, which provides space for the sliding of the components. Through the support of the chassis 41, the fixation of the inner filter element 42, the guidance of the sliding groove assembly 46, and the space guarantee of the sliding opening 47, the stable assembly and operation of each component of the detachable inner core mechanism 4 can be achieved. The running box mechanism 5 provides a supporting foundation for the rotation of the outer core 1 34. The bearing assembly 36 achieves its own stable operation through the internal connecting column 44. The outer core 2 35 enhances the stability of the overall structure through the fixation of the bottom plate 45.
[0040] Reference Figure 2 , Figure 3 and Figure 4 The bearing assembly 36 includes an outer shaft 361, the top of which is fixedly connected to the bottom of the rotating column 31. An inner shaft 363 is rotatably connected inside the outer shaft 361. Multiple balls 362 are rotatably connected between adjacent outer shaft 361 and inner shaft 363. The elastic assembly 37 includes a spring 371, the top of which is fixedly connected to the bottom of the pressure plate 32. A rotating plate 372 is fixedly connected to the bottom of the spring 371. A fixed plate 373 is fixedly connected between adjacent rotating plate 372 and connecting plate 33. The rotating assembly 38 includes multiple pawls 381, the bottom of which is fixedly connected to the top of the outer core 35. Multiple notches 382 are provided at the bottom of the rotating plate 372.
[0041] Specifically, the top of the outer shaft 361 is fixedly connected to the bottom of the rotating column 31. When the rotating column 31 rotates, it will directly drive the outer shaft 361 to rotate synchronously. The inner shaft 363 is rotatably connected inside the outer shaft 361, and multiple balls 362 are rotatably connected between adjacent outer shaft 361 and inner shaft 363. Through the rotation of the outer shaft 361 and the rolling action of the balls 362, the outer shaft 361 and inner shaft 363 form a relative rotation. This relationship realizes the drag reduction effect during the rotation of the rotating column 31.
[0042] In the elastic component 37, the top of the spring 371 is fixedly connected to the bottom of the pressure plate 32, and the bottom of the spring 371 is fixedly connected to the rotating plate 372. At the same time, the rotating plate 372 and the connecting plate 33 are fixedly connected to a fixed plate 373. When the pressure plate 32 rotates with the rotating column 31, the movement of the pressure plate 32 is transmitted to the rotating plate 372 through the spring 371. Through the elastic force of the spring 371, the movement of the rotating plate 372 can be buffered and stabilized, thereby enhancing the stability of the rotating component 38.
[0043] The rotating assembly 38 includes multiple pawls 381, the bottoms of which are fixedly connected to the top of the outer core 35. The bottom of the rotating plate 372 has multiple notches 382. When the rotating plate 372 moves under the drive of the elastic assembly 37, the notches 382 at the bottom of the rotating plate 372 combine with the pawls 381 at the top of the outer core 35. Through the engagement and disengagement of the notches 382 and the pawls 381, the movement of the rotating plate 372 in a specific position can be restricted, while allowing it to rotate in a specified direction. This enables the positioning and rotation adjustment of the rotating plate 372 relative to the outer core 35, so that the rotation of the rotating column 31 can be stably and smoothly transmitted to the relevant components, ensuring the overall reliability of the device operation.
[0044] Reference Figure 1 and Figure 5 The chute assembly 46 includes a card holder 461, the rear side of which is fixedly connected to the front side of the outer wall of the connecting column 44. A groove 462 is provided on the rear side of the inner wall of the base plate 45, and the card holder 461 is slidably connected inside the groove 462. The running box mechanism 5 includes a box body 51, the bottom of which is fixedly connected to the top of the base 2. An air inlet pipe 52 passes through the rear side of the outer wall of the box body 51, and an air outlet pipe 6 is fixedly connected to the top of the base 2. The air outlet pipe 6 is slidably connected inside the sliding port 47.
[0045] Specifically, the sliding groove assembly 46 is not only used between the connecting column 44 and the base plate 45, but also between the top plate 43 and the connecting column 44. The connecting column 44 is provided with a bracket 461, and the top plate 43 has a groove 462. The bracket 461 is slidably connected inside the groove 462. Simultaneously, another bracket 461 included in the sliding groove assembly 46 is fixedly connected to the front side of the outer wall of the connecting column 44 at its rear. The rear side of the inner wall of the base plate 45 has a groove 462, and the bracket 461 is slidably connected inside the corresponding groove 462. Through the sliding of the bracket 461 and groove 462 between the connecting column 44 and the top plate 43, and between the connecting column 44 and the base plate 45, the connecting column 44 can move along the extending direction of the groove 462 on the top plate 43 and the base plate 45. This achieves relative sliding between the connecting column 44 and the top plate 43 and the base plate 45, providing a structural basis for adjusting the position of related components of the device.
[0046] An air inlet pipe 52 runs through the rear side of the outer wall of the housing 51, providing a channel for external airflow to enter the housing 51. The air outlet pipe 6 included in the base 2 extends through the top of the base 2 and is slidably connected to the inside of the sliding port 47. When the device is running, external airflow enters the housing 51 through the air inlet pipe 52. After being processed inside the housing 51, the airflow needs to be discharged through the air outlet pipe 6. Since the air outlet pipe 6 is slidably connected to the inside of the sliding port 47, during the operation of the device, the air outlet pipe 6 can be slidably adjusted along the extension direction of the sliding port 47 according to actual needs, so that the airflow can be discharged smoothly from the air outlet pipe 6, avoiding the problem of poor airflow discharge caused by fixed position. At the same time, the sliding of the card holder 461 and the groove 462 in the sliding groove assembly 46 can provide stable guidance for the movement of related components when the connecting column 44 drives them, ensuring the accuracy and smoothness of the component movement, thereby enabling the entire device to operate in a coordinated and stable manner.
[0047] Working principle: External airflow enters the interior of the housing 51 through the air inlet pipe 52 that runs through the rear side of the outer wall of the housing 51 in the operating housing mechanism 5. The air inlet pipe 52 provides a stable channel for airflow to enter. The airflow entering the housing 51 will first come into contact with the adjustable outer core mechanism 3, which is the key part to achieve preliminary filtration and filter pore size adjustment.
[0048] The top of the rotating column 31 is located at the bottom of the top cover 1. When the rotating column 31 rotates, the pressure plate 32 fixedly connected to its bottom will rotate synchronously with the rotating column 31. The connecting plate 33 fixed to the outer wall of the pressure plate 32 will move accordingly, thereby driving the outer core 34 to rotate. This causes the outer core 34 to rotate relative to the outer wall of the outer core 35. Both the outer core 34 and the outer core 35 are provided with filter holes. By changing the size of the overlapping area of the filter holes through the relative rotation of the two, the pore size of the filter holes of the outer core can be adjusted to adapt to different filtration needs.
[0049] The top of the outer core 35 is provided with a rotating component 38. When the connecting plate 33 drives the outer core 34 to rotate, the rotating component 38 provides guidance for the relative rotation between the outer core 34 and the outer core 35, so that the rotation trajectory of the two is stable. The rotating component 38 includes multiple pawls 381. The bottom of the multiple pawls 381 is fixedly connected to the top of the outer core 35. The bottom of the rotating plate 372 is provided with multiple notches 382. When the rotating plate 372 moves under the drive of the elastic component 37, the notches 382 at the bottom of the rotating plate 372 combine with the pawls 381 at the top of the outer core 35. Through the engagement and disengagement of the notches 382 and the pawls 381, the movement of the rotating plate 372 in a specific position is restricted, while allowing it to rotate in a specified direction, so as to realize the positioning and rotation adjustment of the rotating plate 372 relative to the outer core 35.
[0050] The bearing assembly 36 at the bottom of the rotating column 31 reduces the frictional resistance during the rotation of the rotating column 31, ensuring the smooth rotation of the rotating column 31. In the bearing assembly 36, the top of the outer shaft 361 is fixedly connected to the bottom of the rotating column 31. When the rotating column 31 rotates, it directly drives the outer shaft 361 to rotate synchronously. The inner shaft 363 is rotatably connected inside the outer shaft 361, and multiple balls 362 are rotatably connected between the adjacent outer shaft 361 and the inner shaft 363. Through the rotation of the outer shaft 361 and the rolling action of the balls 362, the outer shaft 361 and the inner shaft 363 form a relative rotation, realizing the drag reduction effect during the rotation of the rotating column 31. At the same time, a connecting column 44 is provided inside the bearing assembly 36, which provides a structural connection for the operation of the bearing assembly 36.
[0051] The elastic component 37 at the bottom of the pressure plate 32 applies a limiting effect to the rotating component 38. By limiting the displacement of the rotating component 38, the outer core 34 will not rotate arbitrarily. In the elastic component 37, the top of the spring 371 is fixedly connected to the bottom of the pressure plate 32, and the bottom of the spring 371 is fixedly connected to the rotating plate 372. At the same time, the rotating plate 372 and the connecting plate 33 are fixedly connected to each other by a fixing plate 373. When the pressure plate 32 rotates with the rotating column 31, the movement of the pressure plate 32 is transmitted to the rotating plate 372 through the spring 371. The elastic force of the spring 371 is used to buffer and stabilize the movement of the rotating plate 372, thereby enhancing the stability of the rotating component 38.
[0052] The bottom of the outer core 2 35 is fixedly connected to the base plate 45. The base plate 45 plays a role in fixing the bottom of the outer core 2 35, which enhances the structural stability of the outer core 2 35. The bottom of the outer core 1 34 is slidably connected to the top of the base plate 45, which enables the outer core 1 34 to rotate stably on the base plate 45, further ensuring the reliability of the relative rotation between the outer core 1 34 and the outer core 2 35.
[0053] The airflow that has passed through the adjustable outer core mechanism 3 will enter the detachable inner core mechanism 4. The detachable inner core mechanism 4 is located inside the adjustable outer core mechanism 3. It further improves the filtration accuracy on the basis of the initial filtration. In the detachable inner core mechanism 4, the top of the chassis 41 is fixedly connected to the inner filter element 42, and the top of the inner filter element 42 is fixedly connected to the top plate 43. Through the fixing action of the chassis 41 and the top plate 43, the inner filter element 42 is kept in a stable installation state, so that it can effectively perform filtration work.
[0054] The inner wall of the chassis 41 is provided with a sliding groove assembly 46. The sliding groove assembly 46 is not only used between the connecting column 44 and the base plate 45, but also between the top plate 43 and the connecting column 44. The connecting column 44 is provided with a bracket 461, and the top plate 43 is provided with a groove 462. The bracket 461 is slidably connected inside the groove 462. At the same time, another bracket 461 included in the sliding groove assembly 46 is fixedly connected to the front side of the outer wall of the connecting column 44 at its rear. The inner wall of the base plate 45 is provided with a groove 462 at its rear, and the bracket 461 is slidably connected inside the corresponding groove 462. By sliding the bracket 461 and groove 462 between the connecting column 44 and the top plate 43, and by sliding the bracket 461 and groove 462 between the connecting column 44 and the bottom plate 45, the connecting column 44 can move along the extension direction of the groove 462 on the top plate 43 and the bottom plate 45, realizing the relative sliding between the connecting column 44 and the top plate 43 and the bottom plate 45. This provides a structural basis for the position adjustment of the relevant components of the device. At the same time, when the connecting column 44 drives the relevant components to move, it provides stable guidance to ensure the accuracy and smoothness of the component movement process.
[0055] The bottom of the chassis 41 is provided with a sliding opening 47, which provides space for the sliding of the components. The top of the air outlet pipe 6 included in the base 2 extends through the top of the base 2, and the air outlet pipe 6 is slidably connected inside the sliding opening 47. When the device is running, the airflow after being further filtered by the detachable inner core mechanism 4 needs to be discharged through the air outlet pipe 6. Since the air outlet pipe 6 is slidably connected inside the sliding opening 47, during the operation of the device, the air outlet pipe 6 can be slidably adjusted along the extension direction of the sliding opening 47 according to actual needs, so that the airflow can be discharged smoothly from the air outlet pipe 6, avoiding the problem of poor airflow discharge caused by fixed position.
