Abstract
The utility model discloses an inner nozzle device for a steel pipe inner wall sandblasting process. The inner nozzle device comprises a columnar nozzle main part (1), wherein a blind hole (2) is formed in the center of the columnar nozzle main part (1); three sand outlet holes (3) distributed uniformly are formed in the hole wall of the blind hole (2); the sand outlet holes (3) penetrate out of the columnar nozzle main part (1) from the interior of the blind hole; the sand outlet holes (3) expand outwards in the direction facing to the bottom of the blind hole. According to the utility model, three sand outlet holes expanding outwards and uniformly are formed in the blind hole of the columnar nozzle main par, the blind hole plays roles of sand gathering and distribution, and the sand outlet holes can spray sand all around. All that is needed is to connect the columnar nozzle main part to a sand inlet pipe when the nozzle is in use, and comprehensive and uniform sand blasting to the inner pipe wall can be achieved by lifting the nozzle in a steel pipe back and forth. The inner nozzle device is stable in structure, and can improve the work efficiency and process quality of sand blasting process greatly.
Description
Technical field
The utility model relates to a kind of inner nozzle device, particularly a kind of inner nozzle device for steel pipe inner wall blasting treatment technique.
Background technology
In steel pipe manufacturing, in order to improve the surface quality of steel pipe inner wall, conventionally need the operation through spray quartz sand in steel pipe.And existing sand blasting unit is normally connected to a nozzle by sand-blasting machine by pipeline, then nozzle is filled in to steel duct, nozzle tilts to spray quartz sand towards tube wall, but existing nozzle structurally can only, towards single direction sandblast, need continuous rotary nozzle could on tube wall, spray equably quartz sand.This has just caused poor efficiency and the low quality of sandblast operation.
Utility model content
The purpose of this utility model is, a kind of inner nozzle device for steel pipe inner wall blasting treatment technique is provided.It can improve sandblast efficiency, and improves the uniformity of sandblast.
The technical solution of the utility model: a kind of inner nozzle device for steel pipe inner wall blasting treatment technique, be characterized in: comprise column nozzle body, the center of described column nozzle body is provided with blind hole, the hole wall of blind hole is provided with three equally distributed clearance holes, clearance hole is through to column nozzle body in blind hole, and three clearance holes are outer expanding shape in the direction towards blind hole bottom.
The above-mentioned inner nozzle device for steel pipe inner wall blasting treatment technique, described blind hole bottom is provided with tapered protrusion, can play the effect of poly-sand.
The aforesaid inner nozzle device for steel pipe inner wall blasting treatment technique, the two ends of described clearance hole are all horn-like opening.
The aforesaid inner nozzle device for steel pipe inner wall blasting treatment technique, also comprise that an outer wall is provided with externally threaded tubular connection, two sections of the left and right external diameter difference of tubular connection, blind hole installing with the screw-internal thread fit of blind hole upper end described in the little partial insertion of external diameter, the part that external diameter is large is used for connecting sand-feeding tube road.
Compared with prior art, the utility model is by three sand exports that evenly extend out are set in the blind hole at a column nozzle body, and blind hole plays the effect that a poly-sand distributes, and clearance hole can be accomplished to the even sandblast of surrounding.Use the mouth that touches of the present invention only column nozzle master need be connected to sand-feeding tube road, nozzle is lifted back and forth in steel pipe to the blasting treatment uniformly comprehensively that can realize inner tubal wall.The utility model is stabilized structure not only, and can greatly improve operating efficiency and the processing quality of blasting craft.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is axial perspective figure of the present utility model.
Being labeled as in accompanying drawing: 1-column nozzle body, 2-blind hole, 3-clearance hole, 4-tapered protrusion, 5-tubular connection.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment.A kind of inner nozzle device for steel pipe inner wall blasting treatment technique, as depicted in figs. 1 and 2: comprise column nozzle body 1, the center of described column nozzle body 1 is provided with blind hole 2, the hole wall of blind hole 2 is provided with three equally distributed clearance holes 3, clearance hole 3 is through to column nozzle body 1 in blind hole, and three clearance holes 3 are outer expanding shape in the direction towards blind hole bottom.Described blind hole 2 bottoms are provided with tapered protrusion 4.The two ends of described clearance hole 3 are all horn-like opening.Also comprise that an outer wall is provided with externally threaded tubular connection 5, two sections of the left and right external diameter difference of tubular connection 5, blind hole 2 installing with the screw-internal thread fit of blind hole upper end described in the little partial insertion of external diameter.
