Description

Technical Field

[0001] This utility model relates to the field of high-efficiency sealing, and in particular to a high-efficiency sealing connection structure for a filter assembly. Background Technology

[0002] The efficient sealing connection structure of the filter assembly is a key connecting component that ensures accurate filtration of the media during operation and prevents leakage of unfiltered media and secondary contamination of filtered media.

[0003] Before using the high-efficiency sealing connection structure of the filter assembly, pre-installation preparations are necessary. These include cleaning impurities and oil stains from the filter assembly body and connection interface surfaces, checking the seals for damage or deformation, and confirming that the specifications of the fastening components match the installation requirements. Then, proceed with the installation: precisely embed the seals into the sealing grooves of the connection interface, align the filter assembly body with the upstream and downstream pipelines or equipment, and then use appropriate fastening components to tighten evenly to the specified torque to ensure a tight seal. After installation, an inspection is required. Test the medium to observe for leaks and confirm that the fastening components are not loose. Regular maintenance of the sealing connection structure is necessary during daily use, including cleaning the sealing surfaces and checking the degree of aging and wear of the seals. When the seals show obvious signs of aging, damage, or decreased sealing performance, they must be disassembled and replaced. First, loosen the fastening components, remove the old seal, clean the sealing groove, replace it with a new seal, and then re-install the sealing connection according to the installation steps and check the sealing effect.

[0004] Insufficient fit of the seals in filter components can trigger a series of chain problems. If the seals are not precisely embedded in the sealing groove during installation, are not tightened evenly to the specified torque, or if impurities or oil contaminants are present on the sealing surface, the seals will not fit tightly against the inner wall of the housing, creating tiny gaps. During operation, these gaps allow unfiltered media to seep into the filtered area, causing secondary contamination of the filtered media. This not only reduces filtration efficiency but may also lead to malfunctions in subsequent equipment that relies on pure media. For example, in liquid filtration systems, contaminated liquid entering precision instruments can cause corrosion or blockage, affecting equipment lifespan and operational stability. Therefore, a highly efficient sealing connection structure for filter components is proposed to address these issues. Utility Model Content

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.

[0031] Reference Figures 1-3The present invention provides an embodiment of a high-efficiency sealing connection structure for a filter assembly, comprising a lower filter cylinder 1, wherein a sealing mechanism 2 and a quick-release mechanism 3 are provided inside the lower filter cylinder 1. The sealing mechanism 2 includes a base 211, which serves as the mounting base for the overall structure. It is fixed to the working position through an outer wall mounting hole 220, supporting the lower filter cylinder 1 and other components to ensure the filter assembly is stable after installation and to prevent shaking during operation from affecting the sealing and filtration effect. A lower outer shell 212 is fixedly connected to the outer wall of the lower filter cylinder 1. The lower outer shell 212 connects the lower filter cylinder 1 and the lower fixing block 213, providing installation space for the wedge block 314, spring 213, etc. of the quick-release mechanism 3, and simultaneously cooperating with the sealing ring 217 to achieve sealing. A sealing ring 217 is inserted into the inner wall of the lower outer shell 212. The lower fixing block 213 is connected to the upper fixing block 214 via fixing studs 311, achieving initial docking of the upper outer shell 215 and the lower outer shell 212. Simultaneously, by interlocking with the wedge block 314, the connection stability of the upper and lower components is enhanced. The inner wall of the lower fixing block 213 is detachably connected to the upper fixing block 214 via fixing studs 311. The fixing studs 311 connect the upper fixing block 214 and the lower fixing block 213, achieving initial fixing of the upper and lower components and providing basic docking conditions for subsequent sealing operations, ensuring precise alignment of the upper outer shell 215 and the lower outer shell 212. The upper fixing block 214 connects the upper outer shell 215 and the lower fixing block 213, completing the initial fixing of the upper and lower components via fixing studs 311, thus facilitating the connection between the upper filter cartridge 216 and the upper outer shell 212. 5. Provides an installation foundation to ensure precise docking of the upper and lower filter components. The upper fixing block 214 has an upper outer shell 215 fixedly connected to its side wall. The upper outer shell 215 supports the upper filter cylinder 216 and the studs 218 and sliding shell 219 of the sealing mechanism 2, etc. It docks with the lower outer shell 212 to form a closed space, and at the same time provides a sealing contact surface for the sealing ring 217. The upper filter cylinder 216 is fixedly connected to the inner wall of the upper outer shell 215. The upper filter cylinder 216 and the lower filter cylinder 1 cooperate to form a complete filtration channel to filter the fluid. It is fixed inside the upper outer shell 215 and can be disassembled synchronously with the upper outer shell 215 for easy cleaning or replacement, ensuring filtration efficiency. The inner wall of the upper outer shell 215 is threaded with a stud 218, which rotates along the thread of the inner wall of the upper outer shell 215. The sliding shell 219 is pushed downwards, converting rotational power into sealing pressure, causing the sealing ring 217 to fit tightly against the outer shell. The bottom end of the stud 218 is rotatably connected to the sliding shell 219. The sliding shell 219 slides within the upper outer shell 215, causing the sealing ring 217 to move synchronously, transmitting the thrust of the stud 218 to the sealing ring 217, ensuring that the sealing ring 217 is evenly stressed, and providing installation space for the sliding block 222, facilitating the removal of the sealing ring 217. The bottom end of the sliding shell 219 is fixedly connected to the sealing ring 217. Under the push of the sliding shell 219, the sealing ring 217 is in close contact with the inner walls of the upper outer shell 215 and the lower outer shell 212, filling the gaps to achieve a seal and preventing fluid leakage during filtration. The inner wall of the stud 218 is rotatably connected to a cross-shaped rotating cylinder 223.The cross-shaped rotary cylinder 223 connects the stud 218 to the pull cross-shaped rotary rod 221, limiting the rotation and sliding trajectory of the pull cross-shaped rotary rod 221. This ensures precise operation of the sliding block 222 and stable disassembly of the sealing ring 217. The pull cross-shaped rotary rod 221 is slidably connected to the inner wall of the cross-shaped rotary cylinder 223. The operator presses and rotates the pull cross-shaped rotary rod 221, causing the sliding block 222 to compress the spring 224 and disengage from the sliding shell 219, thus releasing the sealing ring 217 and allowing for its disassembly for cleaning or replacement. Pulling the cross-shaped rotary rod 221... A spring 224 is fixedly connected to the bottom end. Spring 224 connects the sliding shell 219 and the sliding block 222, providing elastic thrust to keep the sliding block 222 in a locked state, thus fixing the sealing ring 217. When compressed, it allows the sliding block 222 to disengage, providing elastic restoring force for disassembling the sealing ring 217. The inner wall of the sliding shell 219 is elastically connected to the bottom end of the sliding block 222 via spring 224. Under the elastic force of spring 224, the sliding block 222 engages with the inner wall of the sliding shell 219, fixing the position of the sealing ring 217. Pulling the cross rod 221 disengages the engagement, releasing the sealing ring 217.

[0032] Reference Figures 1-3 The sealing mechanism 2 also includes a mounting hole 220, which is opened on the outer wall of the base 211 to provide an installation interface for fasteners, so that the base 211 can be stably connected to the working position and ensure the reliable installation of the overall structure. The mounting hole 220 is opened on the outer wall of the base 211. The outer wall of the sealing ring 217 is slidably connected to the inner wall of the upper outer shell 215. The outer wall of the sealing ring 217 is slidably connected to the inner wall of the lower outer shell 212. The outer wall of the sliding shell 219 is slidably connected to the inner wall of the upper outer shell 215. The outer wall of the sliding block 222 is slidably connected to the inner wall of the sliding shell 219. The top of the base 211 is fixedly connected to the bottom of the lower filter cylinder 1. One end of the spring 224 is fixedly connected to the inner wall of the sliding shell 219, and the other end of the spring 224 abuts against the bottom of the sliding block 222.

[0033] Reference Figure 2 , Figure 4The quick-release mechanism 3 includes a pull rod 312, which is pulled by the operator to drive the wedge block 314 to compress the second spring 313 and disengage from the lower fixed block 213, thereby releasing the lock of the upper and lower components. This is the operating component of the quick-release mechanism 3, simplifying the disassembly process. The outer wall of the pull rod 312 is slidably connected to the inner wall of the lower outer shell 212. The inner wall of the lower outer shell 212 is elastically connected to the wedge block 314 via the second spring 313. The second spring 313 connects the lower outer shell 212 and the wedge block 314, providing elastic thrust to make the wedge block 314... 4. Insert the lower fixing block 213 to lock the connection between the upper and lower components. When compressed, the wedge block 314 is allowed to disengage, providing elastic restoring force for disassembly. The wedge block 314 is inserted into the lower fixing block 213 under the elastic force of the second spring 313, which strengthens the connection stability of the upper and lower components. When the pull rod 312 is pulled, it disengages and the lock is released. The outer wall of the wedge block 314 is inserted into the inner wall of the lower fixing block 213. One end of the second spring 313 is fixedly connected to the inner wall of the lower outer shell 212, and the other end of the second spring 313 is fixedly connected to the bottom end of the wedge block 314.

[0034] Working principle: The entire structure is fixed in the working position through the mounting holes 220 on the outer wall of the base 211. The upper fixing block 214 and the lower fixing block 213 are aligned and initially connected with the fixing studs 311, so that the upper outer shell 215 and the lower outer shell 212 are connected. The upper filter cylinder 216 and the lower filter cylinder 1 form a filter channel. The studs 218 are rotated, and the studs 218 rotate along the threads on the inner wall of the upper outer shell 215, pushing the sliding shell 219 to slide downward. The sliding shell 219 drives the sealing ring 217 to move synchronously, so that the sealing ring 217 is in close contact with the inner walls of the upper outer shell 215 and the lower outer shell 212 at the same time, achieving a seal. By pressing and rotating the cross rod 221, the sliding block 222 can be disassembled from the sliding shell 219, so that the sealing ring 217 can be cleaned or replaced.

[0035] When the upper and lower filter components need to be disassembled, pull the lever 312. The lever 312 drives the wedge block 314 to slide along the inner wall of the lower outer shell 212. The wedge block 314 compresses the spring 313 and disengages from the lower fixing block 213. The upper outer shell 215 and the upper filter cylinder 216 can then be removed from the lower outer shell 212 as a whole, achieving quick disassembly and facilitating the cleaning or replacement of the filter components.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
