Abstract

The invention relates to a device with a petroleum impurity removing function. The device comprises a spiral ring, wherein the spiral ring comprises an end A and an end B; the end B is arranged on the inner side of the end A in parallel; a filter screen is arranged on the outer side of the spiral ring; a net seam perpendicular to the radial direction of the spiral ring is formed in a joint of the end A and the end B on the filter screen; a plurality of elastic strips are arranged between two side walls of the net seam; two fixed rods are arranged at positions, close to the inner side of the end A, on the spiral ring at an interval; two ends of an arc-shaped rod are hinged to the moving ends of the two fixed rods respectively; a connecting rod is hinged to the middle of the arc-shaped rod; one end of a spring is connected with the moving end of the connecting rod, and the other end of the spring is connected to a position, close to the inner side of the end B, on the spiral ring; the spiral ring is made of an aluminum alloy material. According to the device, the problems that a conventional petroleum pipeline filtering device cannot be disassembled and the filter screen is inconvenient to shrink are solved.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a device for removing petroleum impurities. Background technique [0002] In the process of oil extraction, it mainly includes several processes such as oil drilling, oil transportation, oil storage and oil processing. During oil drilling, some rock fragments and other rubbish will remain in the oil liquid. If these rubbish enter the oil pipeline together with the oil liquid, it will not only increase the load of the oil pipeline, but also reduce the efficiency of oil extraction. In severe cases, oil pipelines are also blocked, so a filter device for filtering petroleum liquids needs to be provided in the oil pipelines. [0003] The simplest device of the filter device of the oil pipeline is a filter screen. The existing filter device is directly fixed on the inner wall of the oil pipeline, which cannot be disassembled, and the existing filter screen is not easy to shrink. C...
