Description

Technical Field

[0001] The present invention relates to the field of air compressors, and specifically to an air compressor filter facilitating filter screen replacement. Background Art

[0002] An air compressor is a device that compresses and stores air. This device is widely used in various fields such as industrial manufacturing, construction, and automotive repair. Its main function is to compress the air in the atmosphere to a higher pressure and store it in an air storage tank for use when needed.

[0003] The filter screen is a key component of an air compressor, which can filter out impurities in the air and prevent these impurities from entering the interior of the air compressor, thereby protecting each component of the machine from damage or performance degradation. The existing Chinese patent publication: CN221536072U discloses a pipeline filter for an air conditioner compressor. During detection, the filter body is fixedly connected to two connecting pipes. When the filter screen has been used for too long, by rotating the mounting frame, the unused filter screen is moved away from the baffle and communicated with the through pipe. When the mounting frame rotates, the convex strip will correspond to the arc groove of the mounting plate of the unused filter screen. At the same time, the sealing strip in the arc groove and the arc convex strip are mutually extruded to seal the filter. At the same time, the seal on the through pipe seals the part of the filter screen not wrapped by the arc groove. After the replacement is completed, the used filter screen is disassembled and replaced by turning the screw, so that the filter screen of the pipeline filter can be replaced without stopping the equipment operation. Although it can achieve non-stop replacement of the filter screen, with the entry of air, some particulate impurities in the air will adhere to the surface of the filter screen. If the filter screen is directly rotated, the particulate impurities on the surface of the filter screen will be scraped off from the filter screen by the sealing strip, causing the particulate impurities to stay in the through pipe. As the particulate impurities increase, it is easy to cause the situation of through pipe blockage. Summary of the Invention

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Please refer to Figures 1 - 8, An air compressor filter that facilitates the replacement of the filter screen in the figure, including a filter body 1 and two partitions 2 symmetrically and fixedly installed inside the filter body 1. The filter body 1 is a cylindrical structure. A turntable 3 is arranged between the two partitions 2. The two sides of the turntable 3 are in contact with the two partitions 2. Two symmetrically distributed mounting frames 4 are slidably installed on the outer side of the turntable 3. Two insertion cavities for the two mounting frames 4 to be limited and inserted are opened on the outer side of the turntable 3. A multi-layer filter screen 5 is arranged inside the mounting frame 4. Two symmetrically distributed flow guide cylinders 6 are fixedly installed inside the filter body 1. The inner side of the flow guide cylinder 6 is an inclined surface structure. Docking pipes 28 are fixedly installed at both ends of the filter body 1, so that the filter body 1 is docked with the pipeline of the air compressor through the two docking pipes 28; also includes: a material changing mechanism for safely switching the two mounting frames 4, and the material changing mechanism is installed inside the filter body 1; a material taking mechanism for taking out the multi-layer filter screen 5 inside the mounting frame 4, and the material taking mechanism is installed inside the mounting frame 4; a disassembly and cleaning mechanism for disassembling and cleaning the mounting frame 4, and the disassembly and cleaning mechanism is installed at the bottom of the filter body 1;

[0031] When replacing the multi-layer filter screen 5, the driving motor 11 can drive the corresponding positioning rod 10 to rotate through the synchronous belt 12, so that the positioning rod 10 drives the turntable 3 to rotate, replacing the positions of the two multi-layer filter screens 5. At the same time, the turntable 3 drives the two mounting frames 4 to rotate synchronously, so that the two abutting rods 9 on the baffle 7 slide out from the inside of the insertion cylinder 16, enabling the abutting rods 9 to move along the inside of the partition 2. By using the displacement of the abutting rods 9, the baffle 7 squeezes the multi-layer filter screen 5, facilitating the air-permeable filter plate 8 on the baffle 7 to be retracted into the inner position of the mounting frame 4, preventing the particulate impurities on the air-permeable filter plate 8 from falling inside the filter body 1 during the rotation of the baffle 7, facilitating the staff to take out the baffle 7 and clean the particulate impurities on the air-permeable filter plate 8, thus achieving the effect of facilitating air filtration and preventing blockage.

[0032] The refueling mechanism includes a baffle 7 slidably installed inside the installation frame 4. The outer side of the baffle 7 is in contact with the outer side of the multi-layer filter screen 5. The outer sides of the baffle 7 and the installation frame 4 are both fixedly installed with breathable filter plates 8, enabling air to enter the multi-layer filter screen 5 through the breathable filter plates 8. Openings corresponding to the size of the breathable filter plates 8 are provided on the outer sides of the partition plate 2 and the turntable 3. On the side of the baffle 7 away from the installation frame 4, two vertically distributed abutting rods 9 are fixedly installed. On the outer side of the partition plate 2, two insertion cylinders 16 for limiting and inserting the abutting rods 9 are provided. The opening of the insertion cylinder 16 is of an arc-shaped structure, and the end of the abutting rod 9 away from the baffle 7 is of an arc-shaped structure, facilitating the removal of the abutting rod 9 from the insertion cylinder 16. A positioning rod 10 is fixedly installed on the side of the turntable 3 close to the partition plate 2. The positioning rod 10 is rotatably installed on the outer side of the partition plate 2, aligning the turntable 3 with the two partition plates 2. A driving motor 11 is fixedly installed inside the guide cylinder 6 on the left side of the filter body 1. The driving motor 11 can rotate intermittently. A synchronous belt 12 is rotatably installed between the output end of the driving motor 11 and the adjacent positioning rod 10. The driving motor 11 drives the turntable 3 to rotate intermittently through the synchronous belt 12 and the positioning rod 10.

[0033] The material taking mechanism includes two L-shaped sliding plates one 13 symmetrically and fixedly installed inside the installation frame 4. On the side of the baffle 7 close to the installation frame 4, two symmetrically distributed L-shaped sliding plates two 14 are fixedly installed. The two L-shaped sliding plates one 13 are respectively in contact with the inner sides of the two L-shaped sliding plates two 14, enabling the L-shaped sliding plates one 13 to be buckled with the L-shaped sliding plates two 14. Three equally spaced spring one 15 are fixedly installed between the inner side of the installation frame 4 and both ends of the baffle 7. Using the elasticity of the spring one 15, the baffle 7 is attached to the surface of the multi-layer filter screen 5. A guiding frame 17 for limiting the sliding of the abutting rod 9 is provided on the outer side of the partition plate 2. The guiding frame 17 is of a U-shaped structure, and the depth of the guiding frame 17 is greater than the depth of the insertion cylinder 16, enabling the baffle 7 to loosen the multi-layer filter screen 5 when the abutting rod 9 is inserted into the guiding frame 17. A material taking opening is provided at the bottom of the filter body 1. The length of the material taking opening is greater than the length of the installation frame 4, for taking out the multi-layer filter screen 5 below the turntable 3. Arc-shaped sealing plates 18 are rotatably installed on both sides of the material taking opening. One end of the arc-shaped sealing plate 18 is fixedly installed with a mounting plate 19. The two mounting plates 19 are butt-jointed by bolts 27, facilitating the opening and closing of the two arc-shaped sealing plates 18. A controller 30 is fixedly installed on the outer side of the filter body 1. The controller 30 extends to the inside of the filter body 1 and is electrically connected to the driving motor 11, for timing the start and stop of the driving motor 11. A rubber sticker 29 is fixedly installed on the top inner wall of the filter body 1. The width of the rubber sticker 29 is greater than the width of the installation frame 4, improving the sealing performance between the installation frame 4 and the baffle 7, facilitating the multi-layer filter screen 5 to filter air;

[0034] When the baffle 7 moves, it can drive the second L-shaped slide plate 14 to move along the inner side of the second L-shaped slide plate 14, improving the smoothness of the movement of the baffle 7 and compressing the first spring 15. When the abutting rod 9 on the baffle 7 is aligned with the guide frame 17 on the partition plate 2, since the depth of the guide frame 17 is greater than the depth of the insertion cylinder 16, the baffle 7 quickly moves away from the multi-layer filter screen 5, facilitating the staff to open the two arc-shaped sealing plates 18 to take out the multi-layer filter screen 5 from the installation frame 4 and insert a new filter screen between the installation frame 4 and the baffle 7, thus achieving the effect of facilitating quick material taking and improving the convenience of replacing the multi-layer filter screen 5.

[0035] Working principle: First, the staff installs the filter body 1 on the pipeline of the air compressor through the two docking pipes 28. When the air compressor operates, the inhaled air can enter the filter body 1. The air enters the opening of the partition plate 2 through the inclined surface of the guide cylinder 6, enabling the breathable filter plate 8 aligned with the opening on the partition plate 2 and the multi-layer filter screen 5 to filter the particulate impurities in the air. The relatively large-particle impurities can adhere to the breathable filter plate 8. When the multi-layer filter screen 5 needs to be replaced, the controller 30 starts the driving motor 11. The driving motor 11 drives the corresponding positioning rod 10 to rotate through the synchronous belt 12, causing the positioning rod 10 to drive the turntable 3 to rotate 180 degrees, realizing the replacement of the positions of the two multi-layer filter screens 5. At the same time, the turntable 3 drives the baffle 7 to rotate through the installation frame 4, causing the two abutting rods 9 on the baffle 7 to slide out from the inner side of the insertion cylinder 16. The abutting rod 9 drives the baffle 7 to move along the inner side of the installation frame 4, retracting the breathable filter plate 8 on the baffle 7 into the inner side of the installation frame 4. Moreover, the baffle 7 drives the second L-shaped slide plate 14 to move along the inner side of the first L-shaped slide plate 13, enabling the baffle 7 to smoothly compress the first spring 15. When the abutting rod 9 is aligned with the guide frame 17, the abutting rod 9 is inserted into the inner side of the guide frame 17. Utilizing the resilience of the first spring 15, the baffle 7 moves away from the multi-layer filter screen 5. Finally, the staff opens the two arc-shaped sealing plates 18, and then the multi-layer filter screen 5 can be taken out between the installation frame 4 and the baffle 7, and the installation frame 4 and the baffle 7 are pulled out from the insertion cavity of the turntable 3 to clean the particulate impurities adhering to the baffle 7, thus achieving the effects of quickly disassembling and replacing the multi-layer filter screen 5 and cleaning the particulate impurities, preventing blockage inside the filter body 1, and ensuring the normal inhalation of air by the air compressor.

[0036] Embodiment 2: Please refer to Figures 3 - 8, This embodiment further elaborates on Embodiment 1. The demolition mechanism shown in the figure includes two mounting blocks 20 symmetrically and fixedly installed on both sides of the mounting frame 4. A sliding cavity for the mounting block 20 to be limited and slide is provided on the outer side of the turntable 3. The length of the sliding cavity is greater than the length of the mounting block 20. A pressing plate 21 is slidably installed inside the sliding cavity. Two symmetrically distributed second springs 22 are fixedly installed between the bottom of the pressing plate 21 and the inner side of the sliding cavity. The mounting block 20 can compress the second spring 22 through the pressing plate 21. Two symmetrically distributed first insertion rods 23 are fixedly installed at the bottom of the mounting block 20. The first insertion rod 23 slidably penetrates through the pressing plate 21. Two symmetrically distributed second insertion rods 24 are arranged below the pressing plate 21. A positioning hole for the second insertion rod 24 to be limited and inserted is provided on the outer side of the first insertion rod 23. When the second insertion rod 24 is inserted into the positioning hole, the mounting block 20 can be locked in the sliding cavity of the turntable 3 through the first insertion rod 23. A push rod 25 is fixedly installed at one end of the second insertion rod 24 away from the first insertion rod 23. The end of the push rod 25 away from the second insertion rod 24 is of an arc-shaped structure, which is convenient for the arc-shaped sealing plate 18 to push the push rod 25 to move. A cavity for the push rod 25 and the second insertion rod 24 to be limited and slide is provided on the outer side of the turntable 3. A third spring 26 is fixedly installed between the push rod 25 and the inner side of the cavity, which is convenient for the push rod 25 to move and reset.

[0037] In this embodiment: When the staff opens the two arc-shaped sealing plates 18, the inner side of the arc-shaped sealing plate 18 can move away from the push rod 25. Using the resilience of the third spring 26, the push rod 25 drives the second insertion rod 24 to be pulled out from the positioning groove of the first insertion rod 23, unlocking the locking of the first insertion rod 23. Then, using the resilience of the second spring 22, the pressing plate 21 pushes the mounting block 20 to move along the sliding cavity of the turntable 3. The mounting block 20 can quickly drive the mounting frame 4 to move out of the insertion cavity of the turntable 3, which is convenient for the staff to remove the mounting frame 4 and the baffle 7 from the turntable 3, and the mounting frame 4 and the baffle 7 can be cleaned. Moreover, when closing the two arc-shaped sealing plates 18, the inner side of the arc-shaped sealing plate 18 can push the push rod 25 to move, so that the second insertion rod 24 is inserted into the positioning groove of the first insertion rod 23 to lock the mounting frame 4. When the turntable 3 rotates, the push rod 25 can move along the arc-shaped sealing plate 18 to the inside of the filter body 1, and keep pressing the push rod 25, thus achieving the effect of being convenient for installation and disassembly.

[0038] Embodiment 3: Please refer to Figures 3 - 7, this embodiment further illustrates other embodiments. On the side of the baffle 7 away from the mounting frame 4, a rubber retaining frame 31 is fixedly installed. The outer side of the rubber retaining frame 31 is in contact with the inner side of the opening on the turntable 3, facilitating the entry of air into the multi-layer filter screen 5. A groove for the limited sliding of the rubber retaining frame 31 is provided on the outer side of the turntable 3, facilitating the removal of the baffle 7 and the mounting frame 4 from the turntable 3. A plurality of equally spaced support rods 32 are fixedly installed on the inner side of the L-shaped sliding plate 13. A slot for the limited sliding of the support rods 32 is provided on the inner side of the L-shaped sliding plate 14, improving the smooth movement of the L-shaped sliding plate 14. A magnet block 33 is fixedly installed at one end of the second insertion rod 24 away from the push rod 25, facilitating the rapid docking of the second insertion rod 24 with the positioning hole on the first insertion rod 23.

[0039] In this embodiment: When the baffle 7 moves, it can drive the rubber retaining frame 31 to move along the inner side of the opening on the turntable 3, improving the sealing performance between the baffle 7 and the turntable 3, facilitating the entry of air into the multi-layer filter screen 5 through the rubber retaining frame 31, providing a guide for the flow of air, and the groove on the turntable 3 facilitates the removal of the baffle 7 driving the rubber retaining frame 31 from the inner side of the turntable 3. When the L-shaped sliding plate 14 moves, the slot on its inner side can move along the support rods 32 on the L-shaped sliding plate 13, improving the smooth movement of the L-shaped sliding plate 14. When the second insertion rod 24 moves, the suction force of the magnet block 33 can be utilized to enable the second insertion rod 24 to quickly insert into the positioning hole on the first insertion rod 23, facilitating the rapid locking of the second insertion rod 24 to the first insertion rod 23.
