[0001] The utility model relates to the technical field of filtering devices, in particular to a natural gas pipeline transportation anti-clogging filtering device. Background Art

[0002] When transporting natural gas, natural gas pipelines need to be equipped with filtering devices, which filter the natural gas through a filter screen to filter out impurities in the natural gas;

[0003] The filtering device in the prior art generally filters through a filter net. Over time, debris accumulates on the filter net, causing the filter net to be blocked and affecting the filtering efficiency of the filter net. In addition, the filter net is inconvenient to replace, resulting in inconvenience in cleaning the filter net, resulting in low filtering efficiency and inconvenience in cleaning the filter net.

[0004] The existing Chinese patent with announcement number CN219596191U discloses an anti-clogging filtering device for natural gas pipeline transportation, including a four-way tube and a butt pipe, both ends of the four-way tube are integrally formed with butt pipes, the top and bottom of the four-way tube are integrally formed with threaded tubes, one end of the threaded tube is threadedly sleeved with a threaded cover, the front of the four-way tube is nested with a front cover, a fixed bearing is fixed through the middle of the front cover, a rotating shaft is fixed through the middle of the fixed bearing, a rolling column is fixed to one end of the rotating shaft and is located inside the four-way tube, a positioning rod is fixed to the other end of the rotating shaft, a through hole is opened in the middle of the rolling column, and two limit rings are fixed to the inner wall of the through hole of the rolling column.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the device disassembles the filter screen for cleaning, some impurities will remain inside the four-way tube, which is not convenient for complete cleaning and needs to be improved; therefore, a natural gas pipeline transportation anti-blocking filtering device is proposed to address the above problems. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve the above-mentioned technical problems, the utility model proposes an anti-clogging filtering device for natural gas pipeline transportation.

A cleaning component is installed, which includes a rotating cylinder, which is installed inside the connecting pipe. A scraper is fixedly connected to one end of the rotating cylinder, and an impeller is fixedly connected to the center of the scraper. The natural gas pipeline is connected to the connecting pipe through a connecting flange, so that the natural gas is transported through the connecting pipe, and impurities in the natural gas are filtered through the filter screen. When cleaning is required, the sealing cover can be opened to simultaneously take out the filter screen, and impurities attached to the surface can be cleaned. When the natural gas flows, the gas drives the impeller to rotate so that the scraper can clean the surface of the filter screen, thereby reducing the attachment of impurities and improving the long-term filtering effect of the filter screen.

[0008] Preferably, connecting flanges are respectively installed at the right end and the upper end of the connecting pipe.

[0009] Preferably, the scraper is configured in a cross shape.

One end of the connecting ring 1 is fixedly connected to a trumpet-shaped conduit. When the natural gas flows, the baffle is pushed to rotate and open to divert the flow. When the natural gas stops flowing, the baffle blocks the conduit through the torsion spring shaft, thereby retaining the filtered impurities in the rotating cylinder.

[0028] The right end and the upper end of the connecting pipe 1 are respectively installed with connecting flanges 3.

[0029] Embodiment 2

[0030] For comparison with Example 1, please refer to Figure 4-5 As shown, the utility model provides another embodiment, in which the scraper 68 is configured in a cross shape.

[0031] The inner wall of the connecting pipe 1 is provided with a raised layer 8, and the connecting ring 2 67 is limited by the raised layer 8.

[0032] One end of the rotating cylinder 61 is threadedly connected to a connecting ring 62. The rotating cylinder 61 and the connecting ring 62 can be disassembled to facilitate pouring out impurities inside the rotating cylinder 61. One end of the connecting ring 62 is fixedly connected to a trumpet-shaped conduit 63. When natural gas flows, the baffle 64 is pushed to rotate to open the diversion flow. When the natural gas stops flowing, the baffle 64 blocks the conduit 63 through the torsion spring shaft, thereby trapping the filtered impurities in the rotating cylinder 61.

[0033] A baffle 64 is hinged at the opening of the conduit 63 via a torsion spring shaft.

[0034] One end of the connecting ring 1 62 is fixedly connected to a spring 66, and the end of the spring 66 away from the connecting ring 1 62 is fixedly connected to a connecting ring 2 67. During installation, the cleaning component 6 is installed in the connecting pipe 1 before the filter component 4. After the filter pipe is installed, the filter screen plate 42 compresses the spring 66 by pushing the rotating cylinder 61 to cooperate with the raised layer 8. When the filter screen plate 42 is taken out, the rotating cylinder 61 will be ejected synchronously due to the tension of the spring 66, and then the impurities collected inside the rotating cylinder 61 will be synchronously brought out of the connecting pipe 1, thereby achieving relatively comprehensive cleaning of the impurities.

[0035] The filter screen plate 42 is located between the right end and the upper end of the connecting pipe 1 .

[0036] The working principle is to connect the natural gas pipeline with the connecting pipeline 1 through the connecting flange 3, so that the natural gas is transported through the connecting pipeline 1, and the impurities in the natural gas are filtered through the filter screen 42. When cleaning is needed, the sealing cover 5 can be opened to simultaneously take out the filter screen 42, and the impurities attached to its surface can be cleaned. When the natural gas flows, the gas drives the impeller 69 to rotate so that the scraper 68 can clean the surface of the filter screen 42, reduce the attachment of impurities, and improve the long-term filtering effect of the filter screen 42.

[0037] When the natural gas flows, the baffle 64 is pushed to rotate and open to guide the flow. When the natural gas stops flowing, the baffle 64 blocks the conduit 63 through the torsion spring shaft, thereby trapping the filtered impurities in the rotating cylinder 61. During installation, the cleaning component 6 is installed in the connecting pipe 1 before the filter component 4. After the filter pipe is installed, the filter screen plate 42 pushes the rotating cylinder 61 to cooperate with the protrusion layer 8 to compress the spring 66. When the filter screen plate 42 is taken out, the rotating cylinder 61 will be ejected synchronously by the tension of the spring 66, thereby synchronously taking the impurities collected inside the rotating cylinder 61 out of the connecting pipe 1, thereby achieving relatively comprehensive cleaning of impurities.
