Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a dry filter that is easy to replace the filter element. Background Technology

[0002] A dryer filter is a device used to remove impurities and moisture from gases or liquids. It is widely used in refrigeration systems, air conditioning systems, compressed air systems and other fields. Its main function is to prevent impurities and moisture from damaging the system and to ensure the normal operation and efficient functioning of the system.

[0003] In traditional dryer filters, replacing the filter element often requires complex procedures, typically involving the disassembly and reassembly of multiple components. For example, special tools may be needed to disassemble the outer casing and fixing devices. This not only requires operators to have professional skills and knowledge, but the entire process is also time-consuming. For some large or complex dryer filters, it may be necessary to disassemble a large number of auxiliary parts to access the filter element, which increases the difficulty and workload of filter element replacement. Due to the inconvenience of filter element replacement, in practical applications, the filter element often cannot be replaced in a timely manner. As the filter element works in the dryer filter for a long time, its filtration effect will gradually decrease with the increase of usage time, which may affect the normal operation of downstream equipment and may even cause the entire system to malfunction. Utility Model Content

[0004] To at least partially solve the above-mentioned technical problems, this utility model provides a dry filter that facilitates filter element replacement.

[0005] This utility model is achieved using the following technical solution: a dry filter that facilitates filter element replacement, comprising an installation sleeve, a support plate fixedly connected to the inner wall of the installation sleeve, an extension rod fixedly connected to the upper surface of the support plate, a telescopic spring fixedly connected to the inner wall of the extension rod, a gasket fixedly connected to the top of the telescopic spring, a rotating shaft rotatably connected to the upper surface of the gasket, a limit block fixedly connected to the surface of the rotating shaft, a gripping rod fixedly connected to the upper surface of the limit block, a housing engaged with the surface of the limit block, a filter element body disposed inside the housing, and a through groove formed on the surface of the housing.

[0006] The above technical solution facilitates quick and easy filter replacement. Through the cooperation of limiting blocks, telescopic springs, and other structures, the housing and filter body can be easily installed and disassembled. The filter can be disassembled by lifting the gripping rod, rotating the limiting block, releasing the gripping rod, and lifting the housing. The operation steps are simple and save time when replacing the filter. Because the filter can be replaced in a timely and convenient manner, the overall performance of the dryer filter can be prevented from declining due to the filter not being replaced for a long time, thus reducing maintenance costs caused by equipment failure or poor performance.

[0007] As a further improvement to the above solution, the through slot is adapted to the limiting block.

[0008] As a further improvement to the above solution, the limiting block is in contact with the upper surface of the outer shell.

[0009] As a further improvement to the above solution, the surface of the mounting sleeve is threaded with a cover.

[0010] The above technical solution facilitates the maintenance and operation of the internal structure of the dryer filter. When replacing the filter element, the cover needs to be removed first.

[0011] As a further improvement to the above solution, an inlet pipe is fixedly connected to the upper surface of the cover.

[0012] The above technical solution provides an input channel for the dryer filter.

[0013] As a further improvement to the above solution, a discharge pipe is fixedly connected to the lower surface of the mounting sleeve.

[0014] The above technical solution provides an output channel for the dryer filter, ensuring that the dried and filtered material can be discharged smoothly.

[0015] As a further improvement to the above solution, an abutment rod is fixedly connected to the inner wall of the cover, and the abutment rod is in contact with the gripping rod.

[0016] The above technical solution further ensures the stability of the gripping bar when the dryer filter is working normally, thereby enhancing the installation stability of the housing and filter element body.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention allows for easy disassembly of the filter element by lifting the gripping rod, rotating the limiting block, releasing the gripping rod, and lifting the outer casing. The simple operation saves time when replacing the filter element. Because the filter element can be replaced promptly and conveniently, it avoids the overall performance degradation of the dryer filter caused by prolonged filter element neglect, reducing maintenance costs due to equipment malfunction or poor performance. During installation, the cooperation between the telescopic spring and the limiting block, as well as the contact engagement between the limiting block and the upper surface of the outer casing, ensures the secure installation of the outer casing and the filter element body. When the cover is in place, the pressure bar presses down on the gripping rod, further enhancing the stability of the filter element installation and preventing loosening of the filter element connection due to vibration or other factors during equipment operation.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5This embodiment of a dryer filter for easy filter element replacement includes an installation sleeve 1. A support plate 2 is fixedly connected to the inner wall of the installation sleeve 1. An extension rod 3 is fixedly connected to the upper surface of the support plate 2. A telescopic spring 4 is fixedly connected to the inner wall of the extension rod 3. A gasket 15 is fixedly connected to the top of the telescopic spring 4. A rotating shaft 5 is rotatably connected to the upper surface of the gasket 15. A limit block 6 is fixedly connected to the surface of the rotating shaft 5. A gripping rod 7 is fixedly connected to the upper surface of the limit block 6. A housing 8 is engaged with the surface of the limit block 6. A filter element body 9 is disposed inside the housing 8. A through groove 10 is formed on the surface of the housing 8. During installation, first, the angle of the limit block 6 is rotated to match the through groove 10. Then, the through groove 10 on the surface of the housing 8 is aligned with the limit block 6. The locking block 6 presses down on the outer shell 8, allowing it to fit onto the outer surface of the extension rod 3. When the outer shell 8 descends to the bottom of the extension rod 3, the locking block 6 is lifted upward by the gripping rod 7, stretching the telescopic spring 4. Then, the angle of the locking block 6 is rotated again so that it is no longer engaged with the through groove 10. The gripping rod 7 is released, the telescopic spring 4 returns to its original position, and the locking block 6 descends to contact and engage with the upper surface of the outer shell 8, completing the installation of the outer shell 8 and the filter element body 9. When the filter element needs to be replaced, the personnel lift the gripping rod 7 upward, stretching the telescopic spring 4. The angle of the locking block 6 is rotated so that it can pass through the through groove 10. The gripping rod 7 is released, the telescopic spring 4 returns to its original position, allowing the locking block 6 to enter the through groove 10. Then, the outer shell 8 is lifted upward, and the outer shell 8 and the filter element body 9 can be disassembled.

[0029] The through slot 10 is adapted to the limiting block 6. The adapted through slot 10 and the limiting block 6 can ensure that the outer shell 8 can be smoothly fitted onto the extension rod 3. During disassembly, it can ensure that the limiting block 6 can be smoothly disassembled by passing through the through slot 10. The limiting block 6 is in contact with the upper surface of the outer shell 8.

[0030] The mounting sleeve 1 has a cover 11 threadedly connected to its surface, and the cover 11 can be installed and removed by rotating the thread. An inlet pipe 12 is fixedly connected to the upper surface of the cover 11, and the inlet pipe 12 is used to input the substance to be filtered into the dryer filter.

[0031] The lower surface of the mounting sleeve 1 is fixedly connected to the discharge pipe 13, which is used to discharge the filtered material.

[0032] An abutment rod 14 is fixedly connected to the inner wall of the cover 11. The abutment rod 14 contacts the gripping rod 7. When the cover 11 is installed in place, the abutment rod 14 presses down on the gripping rod 7 to prevent the gripping rod 7 from moving upward. After the cover 11 is removed, the abutment rod 14 no longer presses down on the gripping rod 7, and the filter element can be removed.

[0033] In this embodiment of the dryer filter for easy filter element replacement, during installation, the operator first rotates the angle of the limiting block 6 to match the angle of the limiting block 6 with the through groove 10, aligning the through groove 10 on the surface of the outer shell 8 with the limiting block 6. Then, the outer shell 8 is pressed down, allowing it to fit onto the outer surface of the extension rod 3. The pressing continues until the outer shell 8 descends to the bottom of the extension rod 3. When the outer shell 8 reaches the bottom of the extension rod 3, the limiting block 6 is lifted upwards by the gripping rod 7. At this point, the limiting block 6 stretches the telescopic spring 4. Then, the angle of the limiting block 6 is rotated again until it no longer matches the through groove 10. The gripping rod 7 is released, the telescopic spring 4 returns to its original position, and the limiting block 6 descends to contact the upper surface of the outer shell 8, forming a locking structure. This completes the installation of the outer shell 8 and the filter element body 9. Finally, the cover 11 is connected to the housing via a threaded connection. On the surface of the mounting sleeve 1, during installation, when the cover 11 is installed in place, the abutment rod 14 on the inner wall of the cover 11 will press down on the gripping rod 7 to prevent the gripping rod 7 from moving upward, further enhancing the stability of the filter element installation. When the filter element needs to be replaced, the cover 11 is first removed by rotating the cover 11 in the opposite direction to separate it from the mounting sleeve 1. As the cover 11 is removed, the abutment rod 14 no longer presses down on the gripping rod 7. The operator lifts the gripping rod 7 upward, the telescopic spring 4 is stretched, and then the angle of the limiting block 6 is rotated so that the angle of the limiting block 6 can smoothly pass through the through groove 10. The tension on the gripping rod 7 is released, and under the reset of the telescopic spring 4, the limiting block 6 enters the interior of the through groove 10. Finally, the operator lifts the outer shell 8 upward, and the outer shell 8 and the internal filter element body 9 can be disassembled to complete the filter element replacement operation.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
