Put into boiling in the great Chi fill acid solution, alkali liquor or cleanout fluid afterwards to boil, the reciprocating machine cleaning again of the tubing wall after boiling through boiling.Existing
Cleaning device complex structure inside and outside oil pipe, is typically mounted on a cleaning line, easily causes secondary pollution, outer using first cleaning
Clean the mode of inwall after wall, work efficiency can be improved, reduce secondary pollution.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides structure simple, easy to operate oil pipe is clear
Clean device.
The technical scheme in the invention for solving the technical problem is:
A kind of oil pipe cleaning device, including lower flange, outer tube, inner core, joint, upper flange, from sealed cover and self-styled core, institute
The lower flange stated is connected with drilling well-head flange, and in lower flange upper surface, outer tube welded top exists described outer tube bottom welding
Upper flange lower surface, in lower flange upper surface, inner core welded top is in upper flange lower surface, inner core for described inner core bottom welding
Side wall be provided with inclined hole, on outer tube, joint is connected described weld with outer tube inner wall, and described fixes from sealed cover
On upper flange, described self-styled core is fixed on upper flange, for clearing up greasy dirt and sealing.
As optimization, described inclined hole is at 45 ° with axis, makes cleanout fluid form greater impact power and acts on oil pipe.
As optimization, described self-styled core is made by silicone rubber, has acid and alkali-resistance, the characteristic such as high temperature resistant it is ensured that self-styled core
Intensity and life-span.
As optimization, self-styled core includes the work surface a for cleaning, the buffering suface for buffering deformation and is used for cleaning
Work surface b, the work surface of different-diameter forms the cleaning oil pollution of varying strength it is ensured that cleaning oil pollution effect to oil pipe.
As optimization, work surface b is and the tubing diameter identical face of cylinder that the oil residues on oil pipe surface are scraped
Remove.
As optimization, work surface a is taper seat, and the lower disc diameter of taper seat is less than tubing diameter 0.5mm, and upper disc is straight
Footpath is less than tubing diameter 2mm, and the interference fit of work surface a and oil pipe increased the cleaning oil pollution effect on oil pipe surface.
The beneficial effects of the utility model are: compared with prior art, this utility model structure is simple, low cost, operation
Convenient, oil pipe cleaning device is arranged on above well head, oil-pipe external wall is carried out, and improves work efficiency, it is to avoid to week
Enclose ground pollution, decrease inside and outside the generation of secondary pollution simultaneously cleaned.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is self-styled cored structure enlarged drawing in this utility model；
Wherein, 1 lower flange, 2 outer tube, 3 inner cores, the oblique through hole of 3-1,4 joints, 5 upper flanges, 6 from sealed cover, 7 self-styled cores, 7-
1 work surface a, 7-2 buffering suface, 7-3 work surface b, 8 oil pipes.
Specific embodiment
Comprehensive accompanying drawing is described further to specific embodiment of the present utility model below:
As shown in Figure 1, 2 in embodiment, a kind of oil pipe cleaning device, including lower flange 1, outer tube 2, inner core 3, joint 4, on
Flange 5, from sealed cover 6 and self-styled core 7, described lower flange 1 is connected with drilling well-head flange, described outer tube 2 bottom welding
In lower flange 1 upper surface, in upper flange 5 lower surface, described inner core 3 bottom welding is in lower flange 1 upper end for outer tube 2 welded top
Face, inner core 3 welded top is provided with oblique through hole 3-1 in upper flange 5 lower surface, the side wall of inner core 3, and described joint 4 is welded on
On outer tube 2, joint 4 is connected with outer tube 2 inwall, and described is fixed on upper flange 5 from sealed cover 6, and described self-styled core 7 is fixing
On upper flange 5.
In the present embodiment, described self-styled core 7 is made by silicone rubber, plays sealing and cleaning effect, prevents liquid from flowing out
Enter with foreign body, inside self-styled core 7, have the work surface of different-diameter, become including the work surface a7-1 for cleaning, for buffering
The buffering suface 7-2 of the shape and work surface b7-3 for cleaning, described work surface b7-3 is and the tubing diameter identical face of cylinder,
Described work surface a7-1 is taper seat, and the lower disc diameter of work surface a7-1 is less than tubing diameter 0.5mm, work surface a7-1's
