Compared with prior art, the utility model has the advantage of:
(1) part that oil inlet pipe is positioned at staving by the utility model is set to bending section, and the inside wall of the opening direction of bending section and the second cylindrical body is set to tangent, and the axis perpendicular of the opening direction of bending section and the second cylindrical body, during use, the oil be extracted is when flowing into pre-filter chamber through oil inlet pipe, flow into the direction tangent with pre-flock cavity wall, centrifugal vortex is formed in pre-filter chamber, sandstone because of density larger, sedimentation in centrifugal process, and oil because of density less, float in centrifugal process, the oil floated enters filter cylinder through transition conduit and filters, the sandstone avaled is collected by cartridge, thus realize being separated of oil and sandstone, the wherein formation of centrifugal vortex, can accelerate being separated of oil and sandstone, and separating effect is relatively better, is convenient to promote the use of.
(2) pre-filter chamber of the present utility model from up to down comprises the first cylindrical body, the second cylindrical body and turbination staving successively, and the bucket footpath of the first cylindrical body, the second cylindrical body and turbination staving reduces successively, wherein, the use of turbination staving, be convenient to assemble gravel, make gravel enter storage sand bucket by pre-filter chamber and collect; And the bucket footpath of the first cylindrical body is greater than the bucket footpath of the second cylindrical body, make the intensity of the vortex formed in the first cylindrical body relatively weak, be convenient to the precipitation again of the oil that whiz goes out, thus make gravel and oil be able to be separated more fully.
(3) the utility model is provided with a voussoir bottom cartridge, the upper surface of voussoir is arcwall face, tube connector is through storage sand bucket, the end that tube connector is positioned at the part of storage sand bucket leans against on described arcwall face, when sandstone flows out tube connector, can slide along the arcwall face of voussoir, avoid the generation that sandstone directly falls into the phenomenon bottom storage sand bucket, the application life of storage sand bucket can be increased to a certain extent, and then application life of the present utility model can be increased to a certain extent.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.

Detailed description of the invention
For ease of illustrating, below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of Petroleum screen tube of the present utility model, comprise cartridge 4, filter cylinder 6 and the pre-filter chamber 2 with oil inlet pipe 1, the bottom of pre-filter chamber 2 is connected with cartridge 4 by tube connector 3, the upper end of pre-filter chamber 2 sidewall is connected with filter cylinder 6 by transition conduit 5, be provided with filter screen 7 in filter cylinder 6, the top of filter cylinder 6 is connected with petroleum transportation pipeline; Described pre-filter chamber 2 from up to down comprises the first cylindrical body I, second cylindrical body II and the turbination staving III be connected successively.First cylindrical body I, second cylindrical body II reduces successively with the bucket footpath of turbination staving III, namely the bucket footpath of the first cylindrical body I is greater than the bucket footpath of the second cylindrical body II, and the bucket footpath of the second cylindrical body II is greater than the bucket footpath of the upper base of turbination staving III.Between first cylindrical body I and the second cylindrical body II, be connected respectively by arc-shaped transition section between the second cylindrical body II and turbination staving III.Oil inlet pipe 1 is connected with the second cylindrical body II through the sidewall of the second cylindrical body II, the part that oil inlet pipe 1 is positioned at staving is bending section 13, the opening direction of bending section 13 and the inside wall of the second cylindrical body II tangent, and the axis perpendicular of the opening direction of bending section 13 and the second cylindrical body II.
In the present embodiment, be provided with a voussoir 12 bottom cartridge 4, the upper surface of voussoir 12 is arcwall face, and described tube connector 3 is through storage sand bucket, and the end that tube connector 3 is positioned at storage sand bucket abuts against on the arcwall face of voussoir 12.
In the present embodiment, transition conduit 5 is provided with diaphragm valve 9.Sand removing hole 11 is also provided with, for discharging isolated gravel in the bottom of cartridge 4.Sand removing hole 11 is provided with control valve 10.Control valve 10 adopts butterfly valve.The number of plies of filter screen 7 is 3 layers.
During use, gravel with petroleum liquid from oil inlet pipe 1, flow rapidly in the middle of pre-filter chamber 2 with the direction tangent with the inside wall of pre-filter chamber 2, eddy current is formed in pre-filter chamber 2, make gravel and the centrifugal rotation of oil, the gravel that density is larger is precipitated to get off, and is discharged by the tube connector 3 bottom turbination staving III; The less oil of density is by after whiz to upper strata, and entering in filter cylinder 6 through transition conduit 5 after being again separated in the first cylindricality cylindrical body, under eventually passing the accurate filtration of filter screen 7, petroleum liquid flows through petroleum transportation pipeline 8 and transfers to that other are local.
Wherein, the use of the pre-filter chamber 2 of the utility model, just removes the gravel that in oil, volume is larger, avoids gravel and clash into filter screen 7 under the drive of oil before oil filters, thus destroys filter screen 7, considerably increases the application life of Petroleum screen tube.
