here is the further optimization and/or improvements to foregoing invention technical scheme:
above-mentioned spin rinse cylinder can be provided with an eccentric flushing hole.
above-mentioned spin rinse cylinder can be provided with the identical flushing hole of at least two eccentric directions, flushing hole circumferentially distributes.
outside the upside of above-mentioned spin rinse cylinder with can lead respectively outside downside oblique become upper punch washing cylinder frustum and undershoot washing cylinder frustum; Flushing hole circle distribution is on upper punch washing cylinder frustum and undershoot washing cylinder frustum; The flushing hole be positioned on upper punch washing cylinder frustum is connected with flushing ring cavity obliquely; The flushing hole be positioned on undershoot washing cylinder frustum is connected with flushing ring cavity obliquely; Lead respectively in target seeker upper end and adapter sleeve lower end and obliquely become can make flushing liquor direct projection to the frustum of stepping down on internal surface of sleeve pipe.
above-mentioned flushing hole can be installed with nozzle.
said nozzle surface can be formed with wear-resistant friction layer through carbide process.
above-mentioned target seeker can be fixed as one with guiding connecting rod.
the middle part of above-mentioned adapter sleeve can be provided with spacing interior land, and the adapter sleeve on the downside of spacing interior land is provided with internal thread, and is fixedly mounted on outside the upside of guiding connecting rod by screw thread, and the upper end of guiding connecting rod withstands on bottom spacing interior land; Adapter sleeve on the upside of spacing interior land is provided with internal thread.
reasonable and compact in structure of the present invention, easy to use; While the sand washing of spin rinse cylinder hydrojet, spin rinse cylinder can fast rotational by flushing liquor effect, greatly improves developing result; When water filling discharge capacity is little, still desanding demand can be met; Nozzle in flushing hole simultaneously can accelerate the flushing liquor throttling through flushing hole, makes sand cleaning fluid form turbulent flow, carries grit screw rising and recycles pit shaft, thus reach the object of efficient de-plugging.
Accompanying drawing explanation
accompanying drawing 1 is that the master of preferred embodiment is depending on partly cuing open structural representation.
coding in accompanying drawing is respectively: 1 is target seeker, and 2 is guiding connecting rod, and 3 is influent stream passage, and 4 is spin rinse cylinder, 5 for rinsing ring cavity, and 6 is intercommunicating pore, and 7 is undershoot washing cylinder frustum, and 8 for stepping down frustum, 9 is nozzle, and 10 is upper punch washing cylinder frustum, and 11 is adapter sleeve, and 12 is spacing inner ring platform.
Detailed description of the invention
the present invention by the restriction of following embodiment, can not determine concrete embodiment according to technical scheme of the present invention and actual conditions.
in the present invention, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. determines according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the invention will be further described:
as shown in Figure 1, this rotation sand washing head comprises target seeker 1, spin rinse cylinder 4 and the adapter sleeve 11 in inversed taper platform shape wide at the top and narrow at the bottom; Be fixed with guiding connecting rod 2 in the upper end of target seeker 1, in target seeker 1 and guiding connecting rod 2, be provided with the influent stream passage 3 of opening upwards; The spin rinse cylinder 4 that can rotate is set with at the lower outside of guiding connecting rod 2, in spin rinse cylinder 4, be provided with groove and and is formed and rinses ring cavity 5 between guiding connecting rod 2, on the guiding connecting rod 2 inside flushing ring cavity 5, circle distribution has the intercommunicating pore 6 that influent stream passage 3 can be made to be connected with flushing ring cavity 5; Rinsing the flushing hole spin rinse cylinder 4 outside ring cavity 5 being provided with bias; Adapter sleeve 11 is installed with in the upside of guiding connecting rod 2.During use, first the present invention is arranged on connected pipes by adapter sleeve 11, and together down to the horizontal segment of oil well; Circulated by ground turn on pump, flushing liquor enters into influent stream passage 3 through connected pipes, then sprays from flushing hole through intercommunicating pore 6, flushing ring cavity 5; Because flushing hole adopts eccentric design, while hydrojet sand washing, spin rinse cylinder 4 can fast rotational by flushing liquor effect, greatly improves developing result, when water filling discharge capacity is little, still can meet desanding demand; Reduce water resource waste simultaneously, reduce operation labor intensity.
