Description

Technical Field

[0001] This utility model relates to the field of pipeline filtration technology, and in particular to a filter screen and an unloading pipeline filtration device including the filter screen. Background Technology

[0002] In oilfield operations, brine, clean water, chemicals, and crude oil are transported to the work site by tanker trucks, working in conjunction with pump trucks, hot oil trucks, or water injection pumps and oil transfer pumps. One problem is that impurities in the tanker trucks and liquids are not completely removed, frequently causing malfunctions in various oil transfer pumps, centrifugal pumps, and pump trucks, affecting work efficiency. Repairs can lead to downtime of several hours or even more than ten hours. Although various pumps are equipped with filters to reduce the impact of impurities on pump efficiency, construction equipment such as pump trucks and hot oil trucks are not equipped with filtration devices, failing to effectively remove impurities. Therefore, it is considered to install an additional filtration device before unloading crude oil or other liquids to control impurities and reduce their entry into the work equipment. Specifically, existing technology involves using filtration devices installed in pipelines.

[0003] For example, a Chinese patent with publication number CN202490497U was found, which discloses a pipeline filter, including a filter element (1), a flange (2), and a straight pipe (3). The flange (2) is welded to the straight pipe (3), and the filter element (1) is fitted into the straight pipe (3). The filter element (1) includes a winding wire (5), with a boss (4) and a metal plate (6) welded to both ends of the winding wire (5). This utility model's filter element is connected by fitting into a straight pipe, which has the advantages of simple structure, low manufacturing cost, convenient disassembly and installation, and good filtration effect. It is suitable for filtering fine particles in fluids and also has the advantages of preventing pipeline blockage and being reusable. However, because the filter element has a metal plate at one end, the axial diameter area between the entire filter element and the pipeline is reduced. The winding wire in the filter element, used for filtering fine particles, further reduces the liquid flow rate, significantly prolonging the unloading time and thus failing to meet the working efficiency requirements. Furthermore, the maintenance and cleaning time is relatively long.

[0004] Therefore, how to provide a filter screen that can solve the above-mentioned drawbacks and an unloading pipeline filtration device including the filter screen has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To achieve the above objectives, this utility model provides a filter screen, as detailed below:

[0006] A filter screen includes a filter body having a plurality of filter holes and an internal chamber. The filter body includes a bottom end and an open end opposite to the bottom end. An outwardly protruding impurity collection groove is provided at a position between the bottom end and the open end of the filter body. The impurity collection groove communicates with the chamber. The direction of the open end toward the bottom end is a first direction, which is the upstream and downstream direction of the pipeline on which the filter screen is installed when using the filter screen.

[0007] Preferably, the filter body has an overlapping structure on its side wall, which overlaps with a load-bearing structure inside the pipeline during use.

[0008] Preferably, a handle structure is provided on the side wall of the filter body. When disassembling the filter, holding the handle structure can separate the overlapping structure of the filter body from the supporting structure.

[0009] Preferably, the collection trough starts from the open end and extends along the first direction to the bottom end.

[0010] Preferably, the filter body is a cylinder, and also includes a U-shaped groove protruding outward in the radial direction on the side wall of the cylinder to form the impurity collection groove.

[0011] Preferably, the open end of the cylinder is radially expanded by a flange to form the overlapping structure.

[0012] Preferably, the open end is provided with a thin rod arranged along the diameter of the open end to form the handle structure.

[0013] Preferably, the cylinder, U-shaped groove, and flange are integrally formed.

[0014] The filter provided by this utility model has the following beneficial effects:

[0015] An impurity collection tank connected to the chamber of the filter body is provided to facilitate impurity collection, minimize the reduction of the pipe flow area, and ensure that unloading time is not prolonged. In actual use, depending on the site installation conditions, the impurity collection tank can be positioned at the lowest point when the filter screen is installed to better collect impurities in the chamber.

[0016] As a preferred option, an overlapping structure is provided to facilitate the quick overlapping of the filter screen into the pipeline.

[0017] Preferably, a carrying handle is provided to facilitate quick removal of the filter from the pipeline.

[0018] Preferably, the collection trough starts from the open end and extends along the first direction to the bottom end, which facilitates the collection of more impurities.

[0019] Preferably, the handle structure is formed by a thin rod, so as to achieve a handle structure that is easy to install and easy to operate while occupying as little flow channel area as possible.
