Description

Technical Field

[0001] The utility model relates to the technical field of oil production pipelines, and more specifically, to an anti-freezing and anti-blocking oil production pipeline. Background Art

[0002] Pipeline is a device connected by pipes, pipe fittings and valves for transporting gas, liquid or fluid with solid particles. Pipeline is widely used in many industries and fields due to its unique characteristics. Pipeline has a wide range of uses, mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

[0003] The existing antifreeze effect of oil extraction pipelines is poor. In cold winter, the oil extraction pipeline is prone to bursting due to the low ambient temperature. In addition, the oil after extraction will contain impurities. In order to improve the quality of the extracted oil, a filtering structure is usually installed inside the oil extraction pipeline. The impurities intercepted by the filtering structure are prone to clogging the filtering structure as the amount increases, thereby causing the oil extraction pipeline to be blocked. At the same time, it is not convenient to clean out the impurities on the filtering structure, resulting in low practicality of its use. Utility Model Content
