Description

Technical Field

[0001] This utility model relates to the technical field of oil pipeline branch pipe filter structure, specifically an oil pipeline branch pipe filter structure that is easy to disassemble. Background Technology

[0002] In the oil transportation sector, branch pipelines serve as crucial channels for diverting crude oil or refined oil from main pipelines to various terminal stages, bearing the heavy responsibility of precise and safe oil transportation. However, during the extraction, transportation, and storage of oil products, it is inevitable that they will be mixed with silt, rust, gum, and other impurities. If these impurities flow into the branch pipelines with the oil flow, they will not only wear down the inner walls of the pipelines, significantly shortening their service life, but also easily clog various precision valves and instrument interfaces, interfering with the normal oil transportation process, and even inducing safety accidents.

[0003] To intercept impurities, traditional oil pipeline branch lines are generally equipped with filter screens. However, existing filter screen structures for oil pipeline branch lines are mostly fixed inside the branch line using welding, flange connections, or other methods. While this type of fixed installation can block impurities to a certain extent, its drawbacks are becoming increasingly apparent. During routine maintenance, the accumulation of impurities causes a sharp drop in filter screen efficiency, requiring frequent cleaning or replacement, thus reducing work efficiency. To address this, we provide an oil pipeline branch line filter screen structure that is easy to disassemble. Utility Model Content

[0004] The purpose of this invention is to provide a filter screen structure for oil pipelines that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveniently disassembled oil pipeline filter structure, comprising a pipe body, wherein a filter screen is disposed inside the pipe body, and a double filter screen is fixedly installed inside the pipe body, consisting of inner and outer layers. The inner layer is made of multiple stainless steel thin folded strips arranged in a regular pattern and then welded together; the outer layer uses a stainless steel outer barrel. This combined filter screen can not only effectively prevent bolts and other parts of different sizes from falling downwards, but also block liquids such as water and oily wastewater, achieving a dual filtration effect. The pipe body is provided with a fixed component and a movable component for easy installation and disassembly of the filter screen, and the movable component includes:

[0006] A fixed ring is fixedly installed inside the tube body. By inserting a filter screen into the tube body, a connecting ring is moved towards the top of the fixed ring. When the connecting ring moves, it causes the insertion rod at the bottom of the insertion shaft to pass through the interior of the limiting block. The trigger block at the bottom of the insertion rod first abuts against the surface of the insertion block. The limiting block is fixedly installed at the top of the fixed ring. A telescopic rod is fixedly installed inside the limiting block. A fixing spring is fixedly installed on the surface of the telescopic rod. The insertion block is fixedly installed on the surface of the telescopic rod. When the trigger block moves to the bottom of the insertion block, the telescopic rod will reset under the action of the fixing spring, so that the insertion block is inserted into the surface of the insertion rod for fixation. When fixed, when disassembling, the connecting ring can be manually pressed to cause the abutment block on the surface of the insertion rod to abut against the surface of the insertion block again. The insertion block is slidably connected inside the limiting block.

[0007] Preferably, a connecting ring is fixedly installed on the surface of the filter screen, a shaft is installed at the bottom of the connecting ring, a rod is fixedly installed inside the shaft, a contact block is slidably connected to the surface of the rod, a movable spring is fixedly installed at the top of the contact block, the movable spring is fixedly installed on the surface of the rod, and a trigger block is fixedly installed at the bottom of the rod. The block slides inside the limiting block and drives the telescopic rod to retract again, thereby releasing the block from restricting the rod and allowing for disassembly. This prevents traditional welded and flange-connected filter screens from being inconvenient for later replacement and cleaning, improving the convenience of filter screen disassembly and speeding up work efficiency.

[0008] Preferably, the fixing component includes: a rotating shaft rotatably connected inside the insertion shaft, a sliding rod slidably connected to the surface of the rotating shaft, the sliding rod slidably connected to the inner wall of the insertion shaft, a fixing plate fixedly installed on the surface of the sliding rod, and an abutment ring fixedly installed at the bottom of the fixing plate, the abutment ring being slidably connected to the surface of the insertion rod.

[0009] Preferably, a positioning plate is fixedly installed on the top of the insertion shaft. The positioning shaft can be manually pulled upward to release the positioning plate and disassemble it. When fixing, the positioning plate needs to be released again, and the torsion block can be manually twisted to drive the rotation of the shaft. When the shaft rotates, it will drive the slide rod to slide on the surface of the shaft. The torsion block is fixedly installed on the top of the shaft and is rotatably connected to the top of the insertion shaft.

[0010] Preferably, a positioning shaft extends through the surface of the torsion block, and a return spring is fixedly installed on the surface of the positioning shaft. When the slide rod slides, it drives the abutment ring to slide downward inside the insertion shaft through the fixing plate, so that the abutment ring abuts against the top of the abutment block to prevent the abutment block from moving. After the abutment is completed, the pulling of the positioning shaft can be manually released, and the positioning shaft will return to its original position under the action of the return spring, so that the positioning shaft is re-inserted into the positioning plate for restriction, which improves the stability and fixing effect of the pipe body and the filter screen installation. The return spring is fixedly installed at the bottom of the torsion block.

[0011] Preferably, the active components are provided in two sets, and both sets of active components are symmetrically arranged with the center line of the filter screen as the axis of symmetry.

[0012] Preferably, the limiting block has a groove inside, which can drive the insert block to slide inside the limiting block; the rotating shaft has an arc groove on its surface, which can drive the sliding rod to slide by rotating the shaft; and the positioning disk has a hole on its surface, through which the positioning shaft can pass to the positioning disk for restriction.

[0013] Compared with the prior art, this utility model provides a filter screen structure for oil pipeline branches that is easy to disassemble, and has the following beneficial effects:

[0014] 1. This easily disassembled oil supply branch pipe filter structure, through the setting of movable components, allows for disassembly by manually pressing the connecting ring, which causes the contact block on the surface of the insert rod to re-abut against the surface of the insert block. This causes the insert block to slide inside the limiting block and then retracts the telescopic rod, releasing the insert block from restricting the insert rod, thus enabling disassembly. This avoids the inconvenience of later replacement and cleaning of filter screens caused by traditional welded and flanged connections, improving the convenience of filter screen disassembly and speeding up work efficiency.

[0015] 2. This easily detachable oil supply branch pipe filter structure, through the setting of the fixing component, drives the contact ring to slide downward inside the insertion shaft through the fixing plate, so that the contact ring abuts against the top of the contact block, preventing the contact block from moving. After the contact is completed, the pull on the positioning shaft can be manually released, and the positioning shaft will be restored under the action of the return spring, so that the positioning shaft is re-inserted into the positioning plate for restriction, thereby improving the stability and fixing effect of the pipe body and filter screen installation.

[0023] like Figures 1-6 As shown, this utility model provides a technical solution: a filter screen structure for an oil pipeline branch pipe that is easy to disassemble, including a pipe body 1, a filter screen 2 inside the pipe body 1, and a double filter screen 6 fixedly installed inside the pipe body 1, consisting of inner and outer layers. The inner layer is made of multiple stainless steel thin folded strips arranged in a regular pattern and then welded together; the outer layer is a stainless steel outer barrel. This combined filter screen can not only effectively prevent bolts and other parts of different sizes from falling downwards, but also prevent water, oily wastewater, and other liquids, achieving a double filtration effect. The pipe body 1 is provided with a fixed component 3 and a movable component 4 for easy installation and disassembly of the filter screen 2, and the movable component 4 includes: a fixed ring 41, a limiting block 42, a telescopic rod 43, a fixed spring 44, an insert block 45, a connecting ring 46, an insert shaft 47, an insert rod 48, an abutment block 49, a movable spring 410, and a trigger block 411.

[0024] The fixing ring 41 is fixedly installed inside the tube body 1. The filter screen 2 is inserted into the tube body 1, causing the connecting ring 46 to move towards the top of the fixing ring 41. When the connecting ring 46 moves, it causes the insertion rod 48 at the bottom of the insertion shaft 47 to pass through the interior of the limiting block 42. The trigger block 411 at the bottom of the insertion rod 48 first abuts against the surface of the insertion block 45. The limiting block 42 is fixedly installed at the top of the fixing ring 41. A telescopic rod 43 is fixedly installed inside the limiting block 42. A fixing spring 44 is fixedly installed on the surface of the telescopic rod 43. The insertion block 45 is fixedly installed on the surface of the telescopic rod 43. When the trigger block 411 moves to the bottom of the insertion block 45, the telescopic rod 43 will reset under the action of the fixing spring 44, thus allowing the insertion block 45 to be inserted into the surface of the insertion rod 48 for fixation. When fixed, disassembly can be performed by manually pressing the connecting ring 46. The contact block 49 on the surface of the movable rod 48 abuts against the surface of the plug 45 again. The plug 45 is slidably connected inside the limiting block 42. A connecting ring 46 is fixedly installed on the surface of the filter screen 2. A plug shaft 47 is installed at the bottom of the connecting ring 46. A plug rod 48 is fixedly installed inside the plug shaft 47. The contact block 49 is slidably connected to the surface of the plug rod 48. A movable spring 410 is fixedly installed at the top of the contact block 49. The movable spring 410 is fixedly installed on the surface of the plug rod 48. A trigger block 411 is fixedly installed at the bottom of the plug rod 48. The plug 45 slides inside the limiting block 42 and drives the telescopic rod 43 to retract again, so that the plug 45 releases the restriction on the plug rod 48, thereby disassembling it. This prevents the filter screen 2 from being inconvenient to replace and clean later due to traditional welding and flange connection, improves the convenience of disassembling the filter screen 2, and speeds up the work efficiency.

[0025] The fixing component 3 includes: a rotating shaft 31, which is rotatably connected inside the insertion shaft 47; a sliding rod 32 is slidably connected to the surface of the rotating shaft 31; the sliding rod 32 is slidably connected to the inner wall of the insertion shaft 47; a fixing plate 33 is fixedly installed on the surface of the sliding rod 32; an abutment ring 34 is fixedly installed at the bottom of the fixing plate 33; the abutment ring 34 is slidably connected to the surface of the insertion rod 48; and a positioning plate 35 is fixedly installed at the top of the insertion shaft 47. Manually pulling the positioning shaft 37 upwards releases the positioning shaft 37 from its fixed position. The positioning plate 35 is restricted and disassembled. When fixing, the positioning plate 35 needs to be released again, and the torsion block 36 is manually turned to drive the rotation of the rotating shaft 31. When the rotating shaft 31 rotates, it will drive the slide rod 32 to slide on the surface of the rotating shaft 31. The torsion block 36 is fixedly installed on the top of the rotating shaft 31. The torsion block 36 is rotatably connected to the top of the insertion shaft 47. The positioning shaft 37 passes through the surface of the torsion block 36. The return spring 38 is fixedly installed on the surface of the positioning shaft 37. When the slide rod 32 slides, it will be driven by the fixing plate 33. The moving contact ring 34 slides downward inside the insertion shaft 47, so that the contact ring 34 abuts against the top of the contact block 49, preventing the contact block 49 from moving. After the abutment is completed, the pulling of the positioning shaft 37 can be manually released, and the positioning shaft 37 will be restored under the action of the return spring 38, so that the positioning shaft 37 is re-inserted into the positioning disk 35 for restriction, which improves the stability and fixing effect of the installation of the tube body 1 and the filter screen 2. The return spring 38 is fixedly installed at the bottom of the torsion block 36. There are two sets of movable components 4, and the two sets of movable components 4 are symmetrically arranged with the center line of the filter screen 2 as the axis of symmetry. The limiting block 42 has a groove 420 inside, which can drive the insertion block 45 to slide inside the limiting block 42. The rotating shaft 31 has an arc groove 310 on its surface, which can drive the sliding rod 32 to slide by rotating the rotating shaft 31. The positioning disk 35 has a hole 350 on its surface, through which the positioning shaft 37 can pass to the positioning disk 35 for restriction.

[0026] When the filter screen structure of the oil supply branch pipe is in use, the filter screen 2 can be inserted into the inside of the pipe body 1, causing the connecting ring 46 to move towards the top of the fixed ring 41. When the connecting ring 46 moves, it will cause the insertion rod 48 at the bottom of the insertion shaft 47 to pass through the inside of the limiting block 42. The trigger block 411 at the bottom of the insertion rod 48 first abuts against the surface of the insertion block 45. When the insertion block 45 is abutted, it will cause the telescopic rod 43 to retract. When the trigger block 411 moves to the bottom of the insertion block 45, the telescopic rod 43 will be reset under the action of the fixed spring 44. The insertion block 45 is fixed to the surface of the insertion rod 48. When fixed, when disassembling, the connecting ring 46 can be manually pressed to make the contact block 49 on the surface of the insertion rod 48 contact the surface of the insertion block 45 again, and make the insertion block 45 slide inside the limiting block 42 and cause the telescopic rod 43 to retract again, so that the insertion block 45 releases the restriction on the insertion rod 48, thereby disassembling. This prevents the filter screen 2 from being inconvenient to replace and clean later due to traditional welding and flange connection, improves the convenience of filter screen 2 disassembly, and speeds up work efficiency.

[0027] When the filter screen 2 is disassembled, the positioning shaft 37 needs to be manually pulled upward to release the positioning shaft 37 from the positioning plate 35 and disassemble it. When fixing, the positioning plate 35 needs to be released again, and the torsion block 36 needs to be manually turned to drive the rotating shaft 31 to rotate. When the rotating shaft 31 rotates, it will drive the slide rod 32 to slide on the surface of the rotating shaft 31. When the slide rod 32 slides, it will drive the abutment ring 34 to slide downward inside the insertion shaft 47 through the fixing plate 33, so that the abutment ring 34 abuts against the top of the abutment block 49 to prevent the abutment block 49 from moving. After the abutment is completed, the pulling of the positioning shaft 37 can be manually released, and the positioning shaft 37 will be restored under the action of the return spring 38, so that the positioning shaft 37 is re-inserted into the positioning plate 35 for restriction, which improves the stability and fixing effect of the installation of the tube body 1 and the filter screen 2.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
