Abstract
The utility model relates to the technical field of oil passage filtering equipment, in particular to an oilfield dirt filter. The oilfield dirt filter comprises a main pipeline, wherein an oil passage inlet is formed in the right side of the main pipeline; an oil passage outlet is formed in the left side of the main pipeline; a branch pipeline with a downward inclination angle is arranged at the middle part of the main pipeline; a plug is mounted at the tail end of the branch pipeline in a sleeving manner; a first-stage filtering plate, a second-stage filtering plate and a third-stage filtering plate are sequentially arranged in the inner cavity of the main pipeline from the right side to the left side; the first-stage filtering plate is arranged at the end close to the oil passage inlet; the inclination angle of the second-stage filtering plate is equal to the inclination angle of the branch pipeline; the third-stage filtering plate is arranged at the end close to the oil passage outlet. The oilfield dirt filter can effectively filter out welding slag, rust and other impurities in the pipelines.
Description
Technical field
The utility model relates to the technical field of oil circuit filter plant, especially a kind of oil field dirt filter.
Background technology
At present, in oilfield process, in oil circuit owing to containing the impurity such as welding slag, iron rust, can be by the device damage such as instrument, booster pump in flow process, and then the phenomenon such as occur damaging because impurity causes instrument impeller, pump valve is not closed completely.For fear of the appearance of above situation, be extremely necessary the dirt in oil circuit to clear up.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem proposing in above-mentioned background technology, the utility model provides a kind of oil field dirt filter, can effectively filter out the impurity such as welding slag, iron rust in pipeline.
The utility model solves the technical scheme that its technical problem adopts: a kind of oil field dirt filter, comprise main pipeline, the right side of main pipeline is oil circuit import, the left side of main pipeline is oil circuit outlet, the middle part of main pipeline is provided with angle of inclination lateral down, the tail end of lateral is set with plug, the inner chamber of main pipeline is disposed with single filter plate from right to left, cascade filtration plate and three-stage filtration plate, single filter plate is arranged at the one end near oil circuit import, the angle of inclination size of cascade filtration plate is consistent with the angle of inclination size of lateral, three-stage filtration plate is arranged at the one end near oil circuit outlet.
Further limit: in cascade filtration plate and lateral, the outward flange of close three-stage filtration plate one side is on same straight line.
Further limit: the size of the filtering holes on single filter plate is greater than the size of the filtering holes on cascade filtration plate, and the size of the filtering holes on cascade filtration plate is greater than the size of the filtering holes on three-stage filtration plate.
The beneficial effects of the utility model: this oil field dirt filter, can effectively filter the impurity such as welding slag, iron rust in pipeline, for the protection of the equipment such as instrument, booster pump in flow process, prevent from causing the phenomenons such as the damage of instrument impeller, pump valve are not closed completely because of impurity.

In figure: 1, main pipeline, 2, oil circuit import, 3, oil circuit outlet, 4, lateral, 5, plug, 6, single filter plate, 7, cascade filtration plate, 8, three-stage filtration plate.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Oil field dirt filter as shown in Figure 1, comprise main pipeline 1, the right side of main pipeline 1 is oil circuit import 2, the left side of main pipeline 1 is oil circuit outlet 3, the middle part of main pipeline 1 is provided with angle of inclination lateral 4 down, the tail end of lateral is set with plug 5, the inner chamber of main pipeline 1 is disposed with single filter plate 6 from right to left, cascade filtration plate 7 and three-stage filtration plate 8, single filter plate 6 is arranged at the one end near oil circuit import 2, the angle of inclination size of cascade filtration plate 7 is consistent with the angle of inclination size of lateral 4, three-stage filtration plate 8 is arranged at the one end near oil circuit outlet 3.
Wherein in cascade filtration plate 7 and lateral 4 near the outward flange of three-stage filtration plate 8 one sides on same straight line.The size of the filtering holes on single filter plate 6 is greater than the size of the filtering holes on cascade filtration plate 7, and the size of the filtering holes on cascade filtration plate 7 is greater than the size of the filtering holes on three-stage filtration plate 8.
Fluid enters main pipeline 1 through oil circuit import 2, filter out larger particles impurity through single filter plate 6, the impurity filtering out is along the gradient of lateral 4, under Action of Gravity Field, be deposited in lateral 4, after filter out large granular impurity through cascade filtration plate 7 again, finally filter granule impurity through three-stage filtration plate 8 again, flow out from oil circuit outlet 3 finally by the fluid filtering.
This oil field dirt filter, can effectively filter the impurity such as welding slag, iron rust in pipeline, for the protection of the equipment such as instrument, booster pump in flow process, prevents from causing the phenomenons such as the damage of instrument impeller, pump valve are not closed completely because of impurity.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
