Description
Technical field
The utility model relates to a kind of compound screen casings of stainless steel ripple, belong to oil production equipment accessories technical field.
Background technique
Currently, the oil recovery filter sieve tube used on oil production equipment is mounted in the lower end of pumping unit pipeline, for preventing mud
Husky sand grains enters in oil pipeline, and silt enters meeting loss oil well pump in pipeline, and oil well pump damage is caused not to be available；Replacement is taken out
Oil pump needs the long period, influences oil yield；Chimney filter is divided into common round and depth type, and commonly round structure is complicated, intensity
Low, filtering traffic area is small, easy silt silt blocking filter layer, and it is short to reduce filter effect service life；The filter of depth type filter sieve tube
Thickness, resistance is big, easily blocks, and service life is short.It installs simultaneously, dismantle inconvenience.I am on June 21st, 2011 with regard to this proposition
Patent application is crossed, the patent No.: " 201120209416.6 " patent name: " stainless steel ripple cylindrical mesh hole type filtering screen pipe for oil production "
And it is patentable on 2 8th, 2012；The screen casing is fabulous by practical effect, solves the defect of general screen pipe,
It extends and uses the time；But it has been investigated that there is also the deficiencies that silt filters paste net, filtering layer cleaning difficulty.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of compound screen casing of stainless steel ripple, and the stainless steel ripple is multiple
Formula screen casing can not only effectively filter silt, increase flow, and can be to sieve self-cleaning.
The technical scheme adopted by the utility model to solve the technical problem is as follows: the compound screen casing of stainless steel ripple, comprising: more
Hole inner tube, outer filter screen casing, internal layer filter sieve tube are drilled with hundreds of circular holes on porous inner tube, and porous inner tube both ends are set respectively
There is screw thread tube head；Outer filter screen casing and internal layer filter sieve tube are respectively wave cylindrical shape, and hundreds of strip-shaped holes are made in surface,
Internal layer filter sieve tube aperture is less than outer filter screen casing aperture；Porous inner tube outer surface is equipped with internal layer filter sieve tube, bonding or weldering
It connects thereon, outer filter screen casing is equipped with outside internal layer filter sieve tube, spacing is equipped between two layers of filter sieve tube, side hoop is mounted on outer layer
The end of filter sieve tube, two outer filter screen casings centres are equipped with intermediate pipe collar, and side hoop and intermediate pipe collar are fixed on porous inner tube
Lock ring is fixed；The internal layer filter sieve tube and outer filter screen casing section are ripple type, the side hoop diameter end with it is porous interior
Pipe diameter is identical, and other end diameter is identical as outer filter screen casing diameter；The intermediate pipe collar both ends diameter and outer filter sieve
Pipe diameter is identical.
The beneficial effects of the utility model are: being equipped with gap among two layers of filter screen, large-sized silt is by outer layer mistake
Screen pipe is blocked on the outside of filter sieve tube, and the silt of small particle enters in the gap among two layers of filter screen, with pumping unit
Piston downlink can be discharged outside outer filter screen casing again, cleanse ectonexine filter sieve tube and reach self clean-up action；Its hole be bar shaped both
The intensity for enhancing net cylinder increases filter area again, increases flow, does not block, not mud sand；It is effective to promote oil production rate
And quality, reduce cost for oil production.

Specific embodiment
As shown in figs. 1-9, the compound screen casing of stainless steel ripple includes: porous inner tube 6, outer filter screen casing 4, internal layer filtering
Screen casing 5 is drilled with hundreds of circular holes 7 on porous inner tube 6, and 6 both ends of porous inner tube are respectively equipped with screw thread tube head 1；Outer filter screen casing 4
It is respectively that wave is cylinder-shaped with internal layer filter sieve tube 5, hundreds of strip-shaped holes are made in surface, and internal layer filter sieve tube aperture is less than outer
Layer filter sieve tube aperture；6 outer surface of porous inner tube is equipped with internal layer filter sieve tube 5, bonds or weld thereon, internal layer filter sieve tube 5
It is equipped with outer filter screen casing 4 outside, spacing is equipped between two layers of filter sieve tube, side hoop 2 is mounted on the end of outer filter screen casing 4,
Intermediate pipe collar 3 is equipped among two outer filter screen casings 4, side hoop 2 and intermediate pipe collar 3 are fixed on lock ring on porous inner tube 6 and fix；Institute
