Description

Technical Field

[0001] This utility model relates to the field of pipeline filtration technology, specifically to a natural gas pipeline end-of-pipe filtration device. Background Technology

[0002] Natural gas pipeline filtration plays a crucial role in the natural gas transportation process. It primarily filters out solid particles, moisture, grease, and other impurities from the natural gas to protect downstream equipment from damage and extend its service life. However, how to quickly disassemble and replace the filter material inside the pipeline to ensure continuous pipeline operation is a pressing issue that needs to be addressed.

[0003] A search revealed that CN211035838U discloses a natural gas filtration pipeline, comprising a pipeline with a fixing mechanism connected to its lower end. The fixing mechanism includes a fixing block fixedly connected to the lower end of the pipeline, with two threaded holes at its lower end. A blocking mechanism is connected to the side wall of the fixing mechanism, and a filtering mechanism is connected to the side wall of the blocking mechanism. A sealing mechanism is connected to the inner wall of the pipeline, with the upper end of the blocking mechanism passing through and extending above it. A compression mechanism is connected to the inner wall of the pipeline, and the upper end of the filtering mechanism is connected to the compression mechanism. In this invention, workers only need to rotate the fixing bolts to replace the filter plate, further preventing pipeline blockage caused by unusable filter plates, reducing worker workload, and indirectly improving worker efficiency.

[0004] When disassembling and replacing the filter plate in the above-mentioned natural gas filter pipeline, the fixing bolts must first be rotated until the mounting block is separated from the fixing block. Then, the mounting block is pulled out to remove the connecting rod and the filter plate from the pipeline.

[0005] The above-mentioned procedures not only take a long time to disassemble and assemble the filter plates, but also cannot guarantee normal filtration in the pipeline during the disassembly and assembly of the filter plates. Utility Model Content

Detailed Implementation

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 2and Figure 5 This utility model provides a technical solution: a natural gas pipeline end filter device, including a main component 1, the main component 1 including a protective shell 11, a switching component 2 inside the protective shell 11, the switching component 2 including sleeves 25 symmetrically arranged inside the protective shell 11, the switching component 2 also including a worm 211 and a worm wheel 231 that can drive the two sets of sleeves 25 to rotate inside the protective shell 11, and a quick-release component 3 is provided in the middle of each sleeve 25, the quick-release component 3 including a filter screen 32 that can filter the pipeline inside the protective shell 11, the quick-release component 3 also including a handle 33 and a spring ring 35 that can quickly install and remove the filter screen 32 at the sleeve 25;

[0027] This design solves the problems of existing technologies, such as the long time required for filter plate disassembly and assembly, and the inability to guarantee normal filtration within the pipeline during the disassembly and assembly process.

[0028] Please see Figure 2 A connecting pipe 13 is fixedly connected to a through slot on one side of the protective shell 11, and a slot 111 is provided on the other side of the protective shell 11. A cover plate 12 is snapped into the protective shell 11 at the slot 111.

[0029] When the connecting pipe 13 and the filter screen 32 are in normal filtration and exhaust, the cover plate 12, which is snapped into the slot 111, can encapsulate and protect another set of filter screens 32 waiting to be replaced, so as to prevent impurities in the external environment from adhering to the surface of the filter screen 32.

[0030] Please see Figure 4 and Figure 5 The switching component 2 also includes a bracket 22, which is symmetrically and fixedly connected to the outside of the housing 11. The switching component 2 also includes a motor 21, which is fixedly installed on the upper part of one of the brackets 22, and the output end of the motor 21 is fixedly connected to the worm gear 211.

[0031] The switching component 2 also includes a rotating shaft 23, which is rotatably connected to the inside of the housing 11. The outside of the rotating shaft 23 is fixedly connected to the worm gear 231, and the worm gear 231 is in contact with the worm 211 and is meshed and rotatably connected.

[0032] Switching component 2 also includes two sets of connecting plates 24, one side of each connecting plate 24 is fixedly connected to the rotating shaft 23, and the other side of each connecting plate 24 is fixedly connected to the sleeve plate 25;

[0033] This design allows for the alternating operation of two sets of discs 25 and quick-release components 3 within the protective casing 11.

[0034] Please see Figure 5 and Figure 6 The quick-release assembly 3 also includes an inner ring plate 31, the size of which matches the inner diameter of the sleeve plate 25, and the inner side of the inner ring plate 31 is fixedly connected to the filter screen 32.

[0035] Quick-release assembly 3 also includes inner groove posts 36, which are symmetrically fixedly connected to both sides of the inner sleeve plate 31. A slide rod 34 is slidably connected inside the inner groove post 36. The outer side of the slide rod 34 is fixedly connected to the handle 33. One side of the handle 33 is fixedly connected to the spring coil 35. The spring coil 35 is fixedly connected to the inner groove post 36 on the side away from the handle 33.

[0036] The switching component 2 also includes a slot 251, which is symmetrically opened on the inner side of the sleeve plate 25. The slot 251 corresponds to the position of the slide bar 34 and the size matches it.

[0037] This design enables quick assembly and disassembly of the quick-release component 3 at point 25 of the housing.

[0038] The working principle and usage process of this utility model are as follows:

[0039] When the filter screen 32 located at the connecting pipe 13 reaches the end of its filtration service life, the motor 21 can be started first to drive the worm gear 211 to rotate at the output end of the motor 21, which in turn drives the worm wheel 231 meshing with the worm gear 211 to rotate the shaft 23 synchronously by 180 degrees, thereby allowing the two sets of sleeve discs 25 and the quick-release assembly 3 in the middle of the sleeve discs 25 to complete the position alternation.

[0040] At this point, the idle filter screen 32 on one side can be transferred to the connecting pipe 13 to continue the filtration work, while the filter screen 32 that has reached the end of its service life is transferred to the other side of the protective shell 11 under the action of the switching component 2.

[0041] Then, remove the cover plate 12 that is snapped into the slot 111. Then, hold the handle 33 with both hands and push it inward. At this time, the slide rod 34 will disengage from the slot 251, and the inner ring plate 31 and filter screen 32 will be disengaged from the sleeve plate 25. Similarly, take out a new set of inner ring plates 31 and align the slide rod 34 with the slot 251. Release the handle 33 so that the slide rod 34 is inserted into the slot 251 under the elastic reset of the spring ring 35 to complete the fixing of the inner ring plate 31 in the sleeve plate 25, and wait for the next disassembly and replacement.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
