Description
Technical field
A kind of sand blasting unit is the utility model is related to, more particularly, to a kind of 360 degree of sandblasting shower nozzles.
Background technology
With the exploitation in oil field, in the exploration and production process for carrying out oil, natural gas etc., because geologic structure is answered
Miscellaneous, subsurface environment is very severe, therefore the OCTG for adapting to complex environment is also developed during being drilled, such as electricity
Sub- drilling rod, heavy weight drill pipe etc.；In inner surface treatment, tubing is not easy to rotate such drilling rod, with traditional inner surface sandblasting shower nozzle
Inner surface treatment requirement can not be met.
Chinese patent CN105215862A discloses a kind of steel pipe surfaces externally and internally sand blasting unit, including interior sand blasting unit, outer
Sand blasting unit and drive device；The interior sand blasting unit includes the first frame, interior sandblasting shower nozzle and swivel joint；It is described
Outer sand blasting unit includes the ring pipe of the second circular frame, outer sandblasting shower nozzle and each sandblasting shower nozzle of connection, the ring pipe
On be provided with the pipe joint for going out sandpipe for connecting sand-blasting machine., will when needing to carry out sandblasting to steel pipe internal-surface and outer surface
First frame is placed in steel tube inner hole, and the second frame is enclosed on outside steel pipe, and the first road wheel and the second road wheel are respectively placed in
In the inner and outer surfaces of steel pipe, swivel joint and pipe joint are connected with the sand efferent duct of sand-blasting machine respectively, utilize drive device
Driving road wheel moves axially along steel pipe, and using sandblasting shower nozzle rotation in the driving of the first motor, can realize inside and outside to steel pipe
The sandblasting operation on surface, operating efficiency is high, and labor intensity is low.
In above-mentioned patent, interior sandblasting shower nozzle needs to drive rotation by rotating mechanism to realize 360 degree of sandblastings, and structure setting is multiple
It is miscellaneous, it is impossible to voluntarily to realize 360 degree of sandblastings.
Utility model content
The purpose of this utility model is exactly to provide a kind of 360 degree of sandblastings the defects of overcoming above-mentioned prior art to exist
Shower nozzle.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of 360 degree of sandblasting shower nozzles, including gun case, support, shower nozzle and screw rod, described gun case both ends are opened
Mouthful, one end is sand upstream end, and one end is sand ejection end, and described shower nozzle is arranged on the sand ejection end of gun case, institute
The sand that the shower nozzle and the sand ejection end of gun case stated form annular sprays ring, described for realizing 360 degree of sandblastings
Support is arranged in gun case, and described screw rod is connected on support through shower nozzle, and described support, which is provided with, accommodates sand
The through hole passed through, the axis of described shower nozzle and the axis of gun case are same axis.
Described screw rod one end is connected on support, and the other end is stretched out on the outside of shower nozzle, and is connected with nut, described nut
The fixation of shower nozzle and gun case is realized with screw rod.
Spacer is arranged with screw rod between shower nozzle and support.
Described spacer uses metal or ceramic material.Spacer plays shower nozzle positioning action, prevents shower nozzle to be inwardly indented, really
Protect sand production rate.
Described shower nozzle uses boron carbide material.
The effect of described support is to ensure that shower nozzle in the center of gun case.
Described shower nozzle is pyramidal structure, so that the sand of the annular sprays ring along sand emission direction, directly
Footpath tapers into, and this structure setting is advantageous in that, in the case where pressure-air remains stable, sand outlet gradually contracting
It is small so that sand has stronger impact velocity, bigger for the impulsive force of pipe material inner wall, and sandblasting effect is more preferable.
During blasting treatment, sand is passed through rack space from gun case, arrived through shower nozzle ejection by the effect of pressure-air
The inwall of tubing, carry out the cleaning of pipe material inner wall oxide skin, polishing；Because the sand ejection end of shower nozzle and gun case forms annulus
The sand of shape sprays ring, so sand sprays in 360 degree of spray regimes, sandblasting is carried out to OCTG inner surface.
During actual grit blasting operation, sandblasting is carried out after shower nozzle enters tubing, during retrogressing, due to for 360 degree of sandblastings, without tubing
Rotation can just clean its inner surface clean, during applied to OCTG inner surface sandblasting, can remove pipe material inner wall oxide skin,
Tubing is set to meet interior spraying conditions.
The inner surface blasting treatment that 360 degree of sandblasting shower nozzles of the present utility model are mainly used in drilling well OCTG uses.
Compared with prior art, the beneficial effects of the utility model are：
1st, spacer is arranged with the screw rod between shower nozzle and support, spacer plays shower nozzle positioning action, prevent shower nozzle to
Interior retraction, it is ensured that sand production rate.
2nd, support is provided with, the effect of support is to ensure that shower nozzle in the center of gun case.
3rd, shower nozzle is pyramidal structure, so that the sand of the annular sprays ring along sand emission direction, diameter by
Gradual change is small, and this structure setting is advantageous in that, in the case where pressure-air remains stable, sand outlet is gradually reduced, and makes
Obtaining sand has stronger impact velocity, and bigger for the impulsive force of pipe material inner wall, sandblasting effect is more preferable.
Brief description of the drawings
Fig. 1 is the structural representation of 360 degree of sandblasting shower nozzles of the present utility model.
Embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
A kind of 360 degree of sandblasting shower nozzles, as shown in figure 1, including gun case 1, support 2, shower nozzle 4 and screw rod 6, gun case
1 both ends open, one end are sand upstream end, and one end is sand ejection end, and shower nozzle 4 is arranged on the sand ejection end of gun case 1,
The sand that the sand ejection end of shower nozzle 4 and gun case 1 forms annular sprays ring, and for realizing 360 degree of sandblastings, support 2 is set
Put in gun case 1, screw rod 6 is connected on support 2 through shower nozzle 4, and support 2, which is provided with, accommodates the through hole that sand passes through, spray
First 4 axis and the axis of gun case 1 are same axis.The effect of support 2 is to ensure that shower nozzle 2 in gun case 1
