Description

Technical Field

[0001] The utility model is applicable to the technical field of natural gas filters, and particularly relates to a natural gas filter element purging device. Background Art

[0002] At present, the natural gas filter is an important equipment in the natural gas transmission system. It is used to filter solid impurities such as iron powder and rust contained in the natural gas transmission pipeline during the process of transporting natural gas. After the natural gas filter completes the filtering work, the solid impurities will adhere to the filter element, and then the filter surface will be cleaned regularly by personnel.

[0003] However, when cleaning the impurities accumulated on the filter surface, the operator usually cleans the filter manually to remove the impurities adhered to the surface. Although this operation method can remove the impurities, it not only increases the labor consumption required for cleaning, but also causes the impurities after cleaning to be unable to be removed from the filter and the inside of the pipeline in a timely and rapid manner. Therefore, we propose a natural gas filter element purge device. Utility Model Content

[0008] A cleaning plate is rotatably mounted on a side surface of the sealing cover away from the fixed pipe, and a side edge of the connecting rod is fixedly connected to an outer surface of the cleaning plate.
