Description

Technical Field

[0001] The invention relates to the field of air compressors, in particular to an air compressor filter which is convenient for filter screen replacement. Background Art

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

[0003] The filter is a key component of the air compressor. It can filter out impurities in the air and prevent these impurities from entering the interior of the air compressor, thereby protecting the various components of the machine from damage or performance degradation. The existing Chinese public patent document: CN221536072U discloses a pipeline filter for an air-conditioning compressor. During detection, the filter body is fixedly connected to two connecting pipes. When the filter is used for a long time, the unused filter is connected to the through pipe away from the baffle by rotating the mounting frame. When the mounting frame rotates, the convex strip will correspond to the arc groove of the mounting plate of the unused filter, and the sealing strip in the arc groove will be connected to the arc groove. The convex strips squeeze each other to seal the filter. At the same time, the seal on the through pipe seals the part of the filter that is not wrapped by the arc groove. When the replacement is completed, the used filter is removed and replaced by turning the screws, so that the filter of the pipeline filter can be replaced without stopping the equipment operation. Although the filter can be replaced without stopping the machine, as the air enters, some particulate impurities in the air will adhere to the surface of the filter. If the filter is rotated directly, the particulate impurities on the surface of the filter will be scraped off the filter by the sealing strip, causing the particulate impurities to remain in the through pipe. As the number of particulate impurities increases, the through pipe is easily blocked. Summary of the invention

The positioning rod 10 is rotatably installed on the outer side of the partition 2 so that the turntable 3 is aligned with the two partitions 2. A drive motor 11 is fixedly installed on the inner side of the guide cylinder 6 located on the left side of the filter body 1. The drive motor 11 can rotate intermittently. A synchronous belt 12 is rotatably installed between the output end of the drive motor 11 and the adjacent positioning rod 10.

Three springs 15 equidistantly distributed are fixedly installed between the inner side of the installation frame 4 and the two ends of the baffle 7. The elasticity of the springs 15 is used to make the baffle 7 stick to the surface of the multi-layer filter screen 5.

When the support rod 9 on the baffle 7 is aligned with the guide frame 17 on the partition 2, since the depth of the guide frame 17 is greater than the depth of the insertion tube 16, the baffle 7 quickly moves away from the multi-layer filter screen 5, making it convenient for the staff to open the two arc-shaped sealing plates 18 to remove the multi-layer filter screen 5 from the installation frame 4 and insert the new filter screen between the installation frame 4 and the baffle 7, thereby achieving the effect of facilitating quick material retrieval and improving the convenience of replacing the multi-layer filter screen 5.

[0024] Working principle: First, the staff installs the filter body 1 on the pipeline of the air compressor through two butt joints 28. When the air compressor is running, the inhaled air can enter the filter body 1, and the air passes through the inclined surface of the guide tube 6 and enters the opening of the partition 2, so that the air permeable filter plate 8 and the multi-layer filter screen 5 aligned with the opening on the partition 2 filter the particulate impurities in the air. Impurities with larger particle sizes can adhere to the air permeable filter plate 8. When the multi-layer filter screen 5 needs to be replaced, the controller 30 starts the drive motor 11, and the drive motor 11 drives the corresponding positioning rod 10 to rotate through the synchronous belt 12, so that the positioning rod 10 drives the turntable 3 to rotate 180 degrees, so as to realize 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 mounting frame 4, so that the two push rods 9 on the baffle 7 slide out from the inner side of the insert tube 16, and the push rods 9 drive The baffle plate 7 moves along the inner side of the mounting frame 4, and the air-permeable filter plate 8 on the baffle plate 7 is received into the inner side of the mounting frame 4. In addition, the baffle plate 7 drives the L-shaped slide plate 2 14 to move along the inner side of the L-shaped slide plate 13, so that the baffle plate 7 can steadily compress the spring 15. When the push rod 9 is aligned with the guide frame 17, the push rod 9 is inserted into the inner side of the guide frame 17, and the rebound force of the spring 15 is used to keep the baffle plate 7 away from the multi-layer filter screen 5. Finally, the staff opens the two arc-shaped sealing plates 18 to remove the multi-layer filter screen 5 from between the mounting frame 4 and the baffle plate 7, and pulls the mounting frame 4 and the baffle plate 7 out of the insertion cavity of the turntable 3, and cleans the particulate impurities adhered to the baffle plate 7, thereby achieving the effect of quickly disassembling and replacing the multi-layer filter screen 5 and cleaning the particulate impurities, preventing the inner side of the filter body 1 from being blocked, and ensuring the normal air intake of the air compressor.

[0026] In this embodiment, when the staff opens the two arc-shaped sealing plates 18, the inner side of the arc-shaped sealing plates 18 can be away from the push rod 25, and the push rod 25 drives the second plug rod 24 to be pulled out from the positioning groove of the first plug rod 23 by the rebound force of the third spring 26, thereby releasing the lock of the first plug rod 23, and then the rebound force of the second spring 22 is used to make the plate 21 push the mounting block 20 to move along the sliding cavity of the turntable 3, and 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 The mounting frame 4 and the baffle plate 7 are removed from the turntable 3 and can be cleaned.
