Description

Technical Field

[0001] This utility model relates to the field of pipeline filter technology, specifically a pressure pipeline filter that is easy to install. Background Technology

[0002] In hydraulic, pneumatic, and other fluid control systems, pressure line filters are key components ensuring stable equipment operation. They filter impurities in the fluid to prevent wear on precision components such as valve assemblies and pump bodies. Traditional filter installation requires long-distance cutting of pipelines and connection to multiple flanges, which not only consumes a lot of time but is also prone to fluid leakage due to misalignment of the sealing surfaces. At the same time, their fixing structure is mostly a one-piece welded type, which makes it difficult to adjust the installation angle in confined spaces and lacks flexibility in adapting to different pipeline layouts.

[0003] Based on the above, the applicant believes the following deficiencies exist:

[0004] Existing devices suffer from drawbacks such as reliance on tools for disassembly and assembly, difficulty in positioning, and cumbersome filter replacement. They require external tools to complete installation and disassembly. During installation, tools such as wrenches and screwdrivers are needed to tighten bolts, nuts, or other fasteners, resulting in numerous steps and a long time consumption. During disassembly, tools are also needed to remove the fixed structure, and additional handling is required if parts are rusted or stuck, further reducing the efficiency of disassembly and assembly. Utility Model Content

[0005] The purpose of this invention is to provide a pressure line filter that is easy to install, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure pipeline filter that is easy to install, including a main pipeline, with first connecting flanges fixedly connected to the left and right ends of the main pipeline, a connecting pipeline installed inside the main pipeline, second connecting flanges fixedly connected to the left and right sides of the connecting pipeline, a sealing detection mechanism provided on the surface of the main pipeline and the connecting pipeline, and a quick-release filter mechanism provided on the surface of the connecting pipeline.

[0007] The quick-release filter mechanism includes a side housing fixedly connected to the top of a connecting pipe. A sealing cap is installed on the top of the second connecting flange. An inner cylinder is provided inside the connecting pipe, and a pull handle is fixedly connected to the top of the inner cylinder. Built-in fixing rings are fixedly connected to the left and right sides of the inside of the connecting pipe. A first magnet is installed inside the built-in fixing ring. Second magnets are installed on the left and right sides of the inner cylinder. A drain hole is provided on the left side of the inner cylinder. A filter element cylinder is installed inside the inner cylinder. An insertion hole is provided on the left side of the inner cylinder. A bottom insertion block is fixedly connected to the left side of the filter element cylinder. An insertion groove is provided on the right side of the inner cylinder. A side insertion block is fixedly connected to the right side of the surface of the filter element cylinder. The inner cylinder is connected to the first magnet on the built-in fixing ring inside the connecting pipe via the second magnets on the left and right sides. The filter cartridges are magnetically attached to each other and fixed in place. During installation, simply align them and the magnetic force will secure them. For disassembly, simply open the top sealing cover, grasp the pull handle, and pull upwards to overcome the magnetic force and remove the inner cylinder from the side shell. No wrenches, screwdrivers, or other tools are needed, greatly improving the efficiency of disassembly and assembly. The filter cartridge and inner cylinder use a double-plug structure. The left side inserts into the plug hole of the inner cylinder through the bottom plug block, and the right side snaps into the plug groove of the inner cylinder through the side plug block. This ensures that the filter cartridge is stable and does not shake during filtration, and when the filter cartridge needs to be replaced, the filter cartridge can be directly pulled out of the inner cylinder without the need to disassemble the fixing parts. This avoids the cumbersome operation of replacing filter cartridges in traditional filters. The quick-release filter mechanism allows for quick disassembly and assembly of the inner cylinder without the need for complicated tools, and the overall positioning is precise and easy to replace.

[0008] Preferably, the built-in fixing ring is arranged in a ring on the inner side of the first magnet block, and the second magnet block is arranged in a ring on the outer ends of the left and right sides of the inner cylinder, with the first magnet block and the second magnet block corresponding to each other.

[0009] Preferably, the bottom plug-in block corresponds to the plug-in hole, the side plug-in block corresponds to the plug-in groove, the bottom plug-in block is inserted into the plug-in hole, and the side plug-in block is inserted into the plug-in groove.

[0010] Preferably, the sealing detection mechanism includes a sealing ring, which is fitted onto the connection between the first connecting flange and the second connecting flange. A locking ring is installed at the outer end of the sealing ring, and a locking hole is opened at the outer end of the surface of the locking ring. A locking bolt is installed inside the locking hole. A connecting ring is installed on the left side of the surface of the connecting pipe, and a pressure detection sensor is installed on the front of the connecting ring.

[0011] Preferably, the sealing ring is installed inside the locking ring, and the detection end of the connecting ring is located inside the connecting pipe.

[0012] Preferably, the main pipeline and the connecting pipeline are flanged together by a first connecting flange and a second connecting flange, and the connecting pipeline is provided with a main pipeline on both the left and right sides.

[0013] Compared with the prior art, this utility model provides a pressure pipeline filter that is easy to install and has the following advantages:

[0014] 1. This easy-to-install pressure pipeline filter features a quick-release filtration mechanism. The inner cylinder is secured by the first magnet on the built-in fixing ring inside the connecting pipe via second magnets on both sides. During installation, simply align the parts and the magnetic force will secure them. For disassembly, simply open the top sealing cover, grasp the pull handle, and pull upwards to overcome the magnetic force and remove the inner cylinder from the side housing. No wrenches, screwdrivers, or other tools are needed, significantly improving disassembly and assembly efficiency. The filter cartridge and inner cylinder use a double-plug structure. The left side inserts into the plug hole of the inner cylinder via the bottom plug, and the right side engages with the plug groove of the inner cylinder via the side plug. This ensures the filter cartridge remains stable during filtration and allows for easy removal of the filter cartridge from the inner cylinder when replacement is needed, without the need for additional disassembly of fixing parts. This avoids the cumbersome operation of replacing filter cartridges in traditional filters. The quick-release filtration mechanism enables rapid disassembly and assembly of the inner cylinder without the need for complex tools, and provides precise positioning and easy replacement.

[0015] 2. This easy-to-install pressure pipeline filter is equipped with a sealing detection mechanism. The main pipeline and connecting pipeline are connected via a first connecting flange and a second connecting flange. A sealing ring is fitted at the connection, and the outer end of the sealing ring is reinforced by a locking ring. Tightening the locking bolt in the locking hole allows the locking ring to apply uniform pressure to the sealing ring, ensuring a tight fit between the sealing ring and the flange connection surface, effectively filling gaps and preventing leakage of the medium in the pressure pipeline from the flange connection. This is suitable for high-pressure operating conditions. Simultaneously, the pressure detection sensor can collect pressure data within the pipeline in real time. When the sealing ring ages or the locking bolt loosens, leading to medium leakage, an abnormal drop in pressure will occur within the pipeline. The pressure detection sensor can promptly detect this change and issue an early warning, reminding personnel to investigate sealing problems and prevent safety accidents or disruptions to normal system operation caused by leakage.

An insertion hole 401 is opened on the left side of the inner cylinder 43. A bottom insertion block 402 is fixedly connected to the left side of the filter element cylinder 49. An insertion groove 403 is opened on the right side of the inner cylinder 43. A side insertion block 404 is fixedly connected to the right side of the surface of the filter element cylinder 49. The inner cylinder 43 is connected to the first magnet 46 on the built-in fixing rings 45 inside the connecting pipe 2 through the second magnets 47 on the left and right sides. 6. The filter cartridge is magnetically attracted and fixed during installation. Simply align the parts and the magnetic force will fix them in place. During disassembly, simply open the top sealing cover 42, grasp the pull handle 44 and pull upwards to overcome the magnetic force and remove the inner cylinder 43 from the side shell 41. No wrench, screwdriver or other tools are needed, which greatly improves the efficiency of disassembly and assembly. The filter cartridge 49 and the inner cylinder 43 adopt a double plug-in structure. The left side is inserted into the plug hole 401 of the inner cylinder 43 through the bottom plug-in block 402, and the right side is inserted into the plug groove 403 of the inner cylinder 43 through the side plug-in block 404. This ensures that the filter cartridge 49 is stable and does not shake during filtration. When the filter cartridge needs to be replaced, the filter cartridge 49 can be directly pulled out from the inner cylinder 43 without the need to disassemble the fixing parts. This avoids the cumbersome operation of replacing the filter cartridge in traditional filters. The quick-release filter mechanism 4 enables quick disassembly and assembly of the inner cylinder 43 without the need for complicated tools. The overall positioning is accurate and easy to replace.

[0032] Example 2

[0033] Please see Figure 1-6 Based on Embodiment 1, the sealing detection mechanism 3 further includes a sealing ring 31, which is fitted onto the connection between the first connecting flange 11 and the second connecting flange 21. A locking ring 32 is installed on the outer end of the sealing ring 31, and a locking hole 33 is opened on the outer end of the surface of the locking ring 32. A locking bolt 34 is installed inside the locking hole 33. A connecting ring 35 is installed on the left side of the surface of the connecting pipe 2, and a pressure detection sensor 36 is installed on the front of the connecting ring 35. The main pipe 1 and the connecting pipe 2 are connected through the first connecting flange 11 and the second connecting flange 21. The sealing ring 31 is fitted onto the connection, and the outer end of the sealing ring 31 is reinforced by the locking ring 32. By tightening the locking bolt 34 in the locking hole 33, the locking ring 32 can apply uniform pressure to the sealing ring 31, so that the sealing ring 31 fits tightly against the flange connection surface, effectively filling the gap and preventing the medium in the pressure pipeline from leaking from the flange connection. This is suitable for high-pressure working conditions. At the same time, the pressure detection sensor 36 can collect the pressure data in the pipeline in real time. When the sealing ring 31 ages or the locking bolt 34 loosens, causing media leakage, the pressure inside the pipeline will drop abnormally. The pressure detection sensor 36 can detect this change in time and issue an early warning, reminding staff to check the sealing problem and avoid safety accidents or affecting the normal operation of the system due to leakage.

[0034] The sealing ring 31 is installed inside the locking ring 32, and the detection end of the connecting ring 35 is located inside the connecting pipe 2;

[0035] The main pipe 1 and the connecting pipe 2 are flanged together by the first connecting flange 11 and the second connecting flange 21. The main pipe 1 is provided on both the left and right sides of the connecting pipe 2.

[0036] In actual operation, when this device is in use, the main pipeline 1 and the connecting pipeline 2 are connected together through the first connecting flange 11 and the second connecting flange 21. The main pipeline 1 and the connecting pipeline 2 are connected through the first connecting flange 11 and the second connecting flange 21. A sealing ring 31 is fitted at the connection, and the outer end of the sealing ring 31 is reinforced by a locking ring 32. It is tightened by the locking bolt 34 in the locking hole 33, which allows the locking ring 32 to apply uniform pressure to the sealing ring 31, so that the sealing ring 31 fits tightly against the flange connection surface, effectively filling the gap and preventing the medium in the pressure pipeline from leaking from the flange connection. It is suitable for high-pressure working conditions. At the same time, the pressure detection sensor 36 can collect the pressure data in the pipeline in real time. When the sealing ring 31 ages or the locking bolt 34 loosens, causing the medium to leak, the pressure in the pipeline will drop abnormally. The pressure detection sensor 36 can detect this change in time and issue an early warning, reminding the staff to check the sealing problem and avoid safety accidents or affecting the normal operation of the system due to leakage.

[0037] The inner cylinder 43 is fixed to the first magnet 46 on the built-in fixing ring 45 inside the connecting pipe 2 by the second magnets 47 on both the left and right sides attracting each other. During installation, it is only necessary to align the position and fix it by magnetic force. During disassembly, simply open the top sealing cover 42, grasp the pull handle 44 and pull upward to overcome the magnetic force and remove the inner cylinder 43 from the side shell 41. No tools such as wrenches or screwdrivers are needed throughout the process, which greatly improves the efficiency of disassembly and assembly. The filter element cylinder 49 and the inner cylinder 43 adopt a double plug-in structure. The left side is connected through the bottom The insertion block 402 is inserted into the insertion hole 401 of the inner cylinder 43, and the right side is inserted into the insertion groove 403 of the inner cylinder 43 via the side insertion block 404. This ensures that the filter cartridge 49 is stable and does not shake during the filtration process, and allows the filter cartridge 49 to be directly pulled out of the inner cylinder 43 when the filter needs to be replaced, without the need for additional disassembly of the fixing parts. This avoids the cumbersome operation of replacing the filter cartridge in traditional filters. The quick-release filter mechanism 4 enables quick disassembly and assembly of the inner cylinder 43 without the need for complicated tools, and the overall positioning is accurate and easy to replace.
