Embodiment
[0018] Such as figure 1 As shown, the improved structure of the shrinkable petroleum primary processing device includes a spiral ring 1, and two symmetrically arranged hooks 13 are arranged on the spiral ring 1. The spiral ring 1 includes an end A11 and an end B12, and the ends B12 are parallel to each other. Set on the inner side of the end A11, the outer side of the spiral ring 1 is provided with a filter screen 2, the filter screen 2 is closed and connected with the spiral ring 1, the filter screen 2 is a double-layer structure, the inner layer has a larger hole diameter than the outer layer, and the inner side of the spiral ring 1 is hinged There are 2 pairs of springs 3 arranged perpendicular to each other, and the 2 springs 3 in each pair are arranged symmetrically with the center of the spiral ring 1, and one of the springs 3 is arranged inside the end B12, and the movable end of the spring 3 is provided with a fixed cylinder 4 , the fixed rod 5 is clamped between the t...

The invention relates to an improved structure of a primary petroleum treatment device with contractile size. The improved structure comprises a spiral ring, wherein the spiral ring comprises an end part A and an end part B, the end part B is parallelly arranged at the inner side of the end part A, a filter net is arranged at the outer side of the spiral ring, the filter net is hermetically connected with the spiral ring, at least one pair of mutually-matched springs is hinged at the inner side of the spiral ring, the two springs are symmetrically arranged with respect to the center of the spiral ring, a fixed barrel is arranged at the movable end of the spring, a fixed bar is clamped between two fixed barrels, and the spiral ring is made from an aluminum alloy material. According to the improved structure provided by the invention, due to the arrangement of the spiral capable of shrinking or expanding, the spring is extruded by the fixed bar, and then the spring generates a restoring force so that the spiral ring is tightly clamped at the inner wall of the petroleum pipeline; the spiral ring can be taken out just by taking out the fixed bar, thus being convenient to install and detach and being simple and convenient to operate.
Description
technical field [0001] The invention relates to the field of petroleum machinery, in particular to an improved structure of a shrinkable petroleum primary processing device. 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 and cannot be disassembled.
