Abstract

The utility model belongs to the technical field of filter elements and particularly relates to a deep sea oil extraction filter element. The deep sea oil extraction filter element is mainly technically characterized by comprising a inner frame with a through hole, and filter screens outside of the inner frame, wherein the filter screens are formed by winding and connecting two or more mesh pieces, and the connecting meshes of the connecting portion of every two mesh pieces are the same to common meshes in size; the edges of the connecting sides of every two neighboring mesh pieces can be in the same direction with weft yarns, the length of the warp yarns of every mesh pieces, which extend out of external weft yarns, is one half of that of the connecting meshes, and the end portions of the opposite warp yarns are fixed in butt joint; the edges of the connecting sides of every two mesh pieces can also be in the diagonal direction of the meshes, and the joints of the corresponding warp yarns and the corresponding weft yarns of every mesh piece are fixed through welding. Therefore, the filter screens wound from the mesh pieces are uniform in filtering precision and almost the same in pass rate, and further the oil extraction quality can be improved.

Description

Deep-sea oil recovery filter core

Technical field

The utility model belongs to filter core technical field, relates in particular to deep-sea oil recovery filter core.

Background technology

In oil recovery field, deep-sea, be used for the filter core filtering, its general configuration is for to have in the internal frame arranged outside with oil-through hole the screen pack being entwined by metal mesh sheet, owing to limited by braiding technique and metal material, the length of metal mesh sheet is restricted, screen pack need to be entwined with two or more metal mesh sheets, mainly contain at present following two kinds: one, by two net sheet docking, adopt silver brazing, between two adjacent net pieces with weld seam, cause filtering accuracy with different by value, affect oil recovery quality; Its two, by corresponding side organizine overlap joint and by being welded and fixed, in lap-joint's organizine chap, the common aperture of the aperture of junction and net sheet is inconsistent, causes equally filtering accuracy and to pass through value different.

Utility model content

The technical problem of solution of the present utility model be just to provide a kind of filtering accuracy high, by being worth essentially identical deep-sea oil recovery filter core.

The technical solution adopted in the utility model is: comprise internal frame and the filter screen that is positioned at this internal frame outside with through hole, described filter screen is entwined by net sheet, described net sheet is formed by connecting above by two or two, and the connection mesh of described two net sheet junctions is identical with the size of common mesh.

Its additional technical feature is:

The edge of described two adjacent net pieces butt joint edges is consistent with tram direction, and outside each net sheet organizine stretches out, the length of tram is half of connection network hole length, and the docking of the end of organizine is fixing relatively;

The edge of described two adjacent net pieces butt joint edges is mesh diagonal, and the organizine that each net sheet is corresponding and the junction of tram are welded and fixed.

Recover the oil with filter core compared with prior art in deep-sea provided by the utility model, have the following advantages: one, due to the internal frame and the filter screen that is positioned at this internal frame outside that comprise with through hole, described filter screen is entwined by net sheet, and described net sheet is formed by connecting above by two or two, and the connection mesh of described two net sheet junctions is identical with the size of common mesh, like this, the strainer filtering precision being wound in this net sheet is consistent, almost identical by being worth, and has improved oil recovery quality; They are two years old, because the edge of described two adjacent net pieces butt joint edges is consistent with tram direction, outside each net sheet organizine stretches out, the length of tram is half of connection network hole length, the docking of the end of organizine is fixing relatively, add man-hour, two net sheet edges of needs docking are sheared along tram direction, the organizine length of stretching out edge tram is half of connection network hole length, then by corresponding organizine end part aligning, adopt Laser Welding that two ends is welded, each solder joint line is consistent with tram direction, processes convenient; They are three years old, because the edge of described two adjacent net pieces butt joint edges is mesh diagonal, the organizine that each net sheet is corresponding and the junction of tram are welded and fixed, each pad line is consistent with common mesh diagonal, although difficulty of processing is larger, but it is stronger that filter screen bears the ability of pressure, and filter screen intensity is large, long service life.

Accompanying drawing explanation

Fig. 1 is to recover the oil with the structural representation in filter core cross section in the utility model deep-sea;

Fig. 2 is the structural representation of the first net sheet connected mode;

Fig. 3 is the structural representation of two side net sheets of the first net sheet connected mode;

Fig. 4 is the structural representation of the second net sheet connected mode;

Fig. 5 is the structural representation of two one-sided net sheets of the second net sheet connected mode.

The specific embodiment

Below in conjunction with accompanying drawing, recovered the oil and be described in further details by structure and the use principle of filter core in the utility model deep-sea.

As depicted in figs. 1 and 2, for recovering the oil with the structural representation in filter core cross section at the utility model deep-sea, the utility model deep-sea oil recovery filter core, comprises internal frame 2 and the filter screen 3 that is positioned at these internal frame 2 outsides with through hole 1, and filter screen 3 is entwined by net sheet 4, net sheet 4 is formed by connecting above by two or two, the connection mesh 5 of two net sheet junctions is identical with the size of common mesh 6, and like this, the strainer filtering precision being wound in this net sheet is consistent, almost identical by being worth, improved oil recovery quality.

As shown in Figures 2 and 3, the direction of two adjacent net pieces 4 junctions, edge is consistent with tram 7 directions, half that outside each net sheet organizine 8 stretches out, the length of tram 7 is connection mesh 5 length, and the docking of the end of organizine 8 is fixed relatively.Add man-hour, two net sheet edges of needs docking are sheared along tram direction, and the organizine length of stretching out edge tram is half of connection network hole length, then by corresponding organizine end part aligning, adopt Laser Welding that two ends is welded, each solder joint line is consistent with tram direction.

As shown in Figure 4 and Figure 5, the edge of two adjacent net pieces butt joint edges is mesh diagonal, the organizine 8 that each net sheet is corresponding and the junction of tram 7 are welded and fixed, each pad 9 lines are consistent with common mesh diagonal, although difficulty of processing is larger, the ability that filter screen bears pressure is stronger, and filter screen intensity is large, solder joint 9 fractures have been avoided causing because pressure is excessive, long service life.

Protection domain of the present utility model is not only confined to above-described embodiment, same or similar by the structure of filter core as long as recover the oil in structure and the utility model deep-sea, just drops on the scope of the utility model protection.
