Description

Technical Field

[0001] This utility model relates to the field of filter material technology, specifically to a filter that facilitates filter element replacement. Background Technology

[0002] A filter is a device that separates impurities, particles, or pollutants from fluids (such as water, air, and oil) through physical interception and adsorption to achieve purification. It is widely used in industrial production, environmental protection, and medical health. The filter element is the core component installed inside the filter. It is mostly made of fibers, metal mesh, porous materials, etc., and directly undertakes the task of filtering impurities. Its filtration accuracy, dirt holding capacity, and other performance parameters determine the purification effect of the filter. The two work together to achieve the filtration and purification of the fluid.

[0003] In existing technologies, replacing filter cartridges requires stopping the machine to disassemble the outer shell and using tools to unscrew parts. The operation is cumbersome and time-consuming, which not only leads to production interruptions and reduced equipment utilization, but also causes wear and deformation of seals due to frequent tool operations, resulting in decreased sealing at the connection between the tank and the top cover, causing fluid leakage or the infiltration of external pollutants. During the replacement process, manual disassembly can easily introduce dust, particles and other impurities due to improper operation, which not only contaminates the filter media, but also aggravates filter screen clogging, shortens the service life of the filter cartridge, and may even cause the filtration system to malfunction due to the accumulation of impurities, increasing equipment maintenance costs and downtime for repairs, and seriously affecting the continuity and reliability of industrial production.

The push plate 20 is used to push the sealing airbag 19.

[0028] An unlocking wedge groove 12 is provided above the plug-in block 9. The inclined surface of the unlocking wedge groove 12 abuts against the unlocking ring block 13. The unlocking ring block 13 is slidably connected in the unlocking ring groove 14, which is located inside the tank body 1.

[0029] A limiting plate 16 is fixedly connected to the side wall of the unlocking ring block 13. The limiting plate 16 is slidably connected within a limiting groove 15, which is located inside the tank body 1.

[0030] The limiting groove 15 and the limiting plate 16 are connected by a limiting spring 17.

[0031] The bottom of the top cover 2 is provided with a threaded groove 6, and a threaded connector 7 is threadedly connected inside the threaded groove 6. A filter screen 5 is connected to the bottom of the threaded connector 7.

[0032] A swaying groove 24 is provided in the threaded connector 7. A vibration rod 26 is slidably connected in the swaying groove 24 through a vibration spring 27. A fixed toothed rod 25 is provided on one side of the vibration rod 26. The fixed toothed rod 25 is fixedly connected in the threaded groove 6. A filter screen 5 is fixedly connected to the bottom of the fixed toothed rod 25.

[0033] The side wall of the tank body 1 has an outlet 4, and the top of the top cover 2 has an inlet 3.

[0034] The threaded connection between the threaded block 7 and the threaded groove 6, and the cooperation between the plug block 9 and the locking plug interface 11, enable the quick installation and fixation of the top cover 2 and the tank body 1 without tools and with stable installation. At the same time, when plugging in, the cross ring 22 pushes the push plate 20 to squeeze the sealing airbag 19 to expand the sealing gap and improve the sealing performance. When replacing the filter element, the top cover 2 can be quickly removed by pushing the unlocking ring block 13 and pressing down the plug block 9. The threaded connection facilitates the disassembly of the filter screen 5. During disassembly, the vibrating rod 26 slides back and forth under the drive of the fixed toothed rod 25 and drives the filter screen 5 to vibrate, loosening the blockage and debris.

[0035] Specifically, this solution mainly addresses the problems in the existing technology of filter element replacement, such as cumbersome and time-consuming operation, the need for tools for disassembly, easy damage to seals, and the introduction of external impurities due to improper operation. These problems can lead to production interruptions, increased maintenance costs, secondary pollution, and system malfunctions. At the same time, it solves the problem of difficult cleaning of clogging debris during filter element disassembly. Through structural design, it achieves convenient filter element replacement, efficient sealing, and automatic filter screen cleaning, reducing maintenance costs and system failures, and ensuring the stable operation of the filtration system.

[0036] The working principle of this utility model is as follows:

[0037] During installation, the filter screen 5 is first connected to the threaded groove 6 at the bottom of the top cover 2 via the threaded connector 7 to ensure a stable connection between the top cover 2 and the filter screen 5. Then, the top cover 2 is placed into the tank body 1. At this time, the top cover 2 and the tank body 1 are connected by the plug-in block 9 and the locking connector 11. The plug-in spring 10 pushes the plug-in block 9 into the connector to achieve initial fixation. At the same time as the plug-in block 9 is inserted into the locking connector 11, the cross ring 22 is abutted, which pushes the push plate 20 to squeeze the sealing airbag 19. At this time, the sealing airbag 19 is squeezed and expands to fill the gap between the tank body 1 and the top cover 2 to form a seal.

[0038] When replacing the filter element, push the unlocking ring 13 down along the unlocking wedge groove 12 to press down the plug block 9. After unlocking, the top cover 2 can be quickly removed. The threaded connection between the threaded block 7 and the threaded groove 6 facilitates the removal of the filter screen 5. During the removal of the filter screen 5, the threaded block 7 slides downward relative to the top cover 2. At this time, the vibrating rod 26 is driven by the fixed toothed rod 25 in the shaking groove 24 and slides back and forth. The vibration spring 27 cooperates to make the vibrating rod 26 vibrate, thereby controlling the filter screen 5 fixedly connected to it to vibrate synchronously, thereby loosening the vibration that blocks the gaps in the filter screen 5, so as to facilitate the subsequent removal of debris.
