Abstract
The utility model discloses a sand blasting apparatus in a long distance pipeline with medium-small caliber. The sand blasting apparatus in the long distance pipeline with medium-small caliber comprises a pipeline (1), a tubular sand collector (5) provided with a horn mouth (7) at the tail part is positioned in the pipeline (1), the outer circumference of the horn mouth (7) is matched with the inner wall of the pipeline (1), an annular sand blasting nozzle (3) is arranged in the annular groove on the inner wall at the front part of the sand collector (5), a gland (2) is arranged at the front end of the sand collector (5), and the gland (2) is provided with a hole (9) matched with the sand blasting nozzle (3). The length for pipeline treatment of the device is greatly increased, the device is time saving and labor saving, and improves the working efficiency.
Description
Technical field:
The utility model relates to sand blasting unit in a kind of pipeline, the sand blasting unit of pipe-line construction and pipeline overhaul engineering inner surface treatment in especially a kind of ground surface works.
Background technology:
Pipeline is in long-time use, because the corrosion of environment and various media will be carried out sandblast to it and carry out surface treatment, existing sand blasting unit operation only can be handled 10m left and right sides pipeline section apart from weak point.Be because the abrasive material of supply spray gun need be carried with the sebific duct of sand-blasting machine, during spraying operation, it is very long that spray gun has backward reasons such as reaction force to make that sebific duct is difficult to.
The utility model content:
In order to overcome the deficiency in the background technology, the utility model provide a kind of in sand blasting unit in the small-bore long-distance pipe.The length that this device is handled pipeline extends greatly, and is time saving and energy saving, improved operating efficiency.
The technical scheme of employing of the present utility model is: in the small-bore long-distance pipe sand blasting unit comprise pipeline, pipeline is built-in with the bell-mouthed tubulose sand trap of afterbody band, bell-mouthed excircle and inner-walls of duct match, annular blast nozzle is arranged in the annular groove of sand trap front inner wall, the sand trap front end has gland, and gland has the hole of matching with blast nozzle.
Above-mentioned blast nozzle inner surface is the conical surface; Surveying outside the sand trap front portion has sweptback conical surface round platform, and the excircle and the inner-walls of duct of round platform match; Card has the tether ring in the annular groove of the shape sand trap of blast nozzle lower end.
The utlity model has following beneficial effect: the sediment transport pipe in this device is exactly on-the-spot by the steel pipe of sandblast, by a sand trap abrasive material is collected, use for the blast nozzle sandblast, thereby be not subjected to distance limit, the treated length of this device can reach about 1000m, is 100 times of existing sand blasting unit.The length of the inner surface of pipeline that device is handled extends greatly, has adapted to the needs of site operation.Solve in the pipe-line construction pipeline internal corrosion surface treatment and old pipeline and do not excavated pipeline internal corrosion surface-treated technical problem in the overhaul engineering; Be suitable for middle small-bore pipeline; The surface treatment rank reaches Sa2～Sa3 level (GB89-23).
Description of drawings:
Fig. 1 is a cutaway view of the present utility model.
The 1-pipeline, 2-gland, 3-blast nozzle, 4-tether ring, 5-sand trap, 6-abrasive material, 7-horn mouth, 8-round platform, 9-hole.
The specific embodiment:
The utility model is described in further detail below in conjunction with embodiment: interior sand blasting unit of small-bore long-distance pipe comprises pipeline 1 in this, pipeline 1 is built-in with the tubulose sand trap 5 of afterbody band horn mouth 7, the excircle of horn mouth 7 and pipeline 1 inwall match and help collecting sand, annular blast nozzle 3 is arranged in the annular groove of sand trap 5 front inner wall, and blast nozzle 3 inner surfaces are that the conical surface helps sandblast.Sand trap 5 front ends have gland 2, and gland 2 has the hole 9 of matching with blast nozzle 3.The anterior outer sand trap 5 that has sweptback conical surface round platform 8, the excircle of round platform 8 and pipeline 1 inwall to match the to reduce resistance that moves ahead of surveying of sand trap 5.Card has tether ring 4 in the annular groove of the shape sand trap 5 of blast nozzle 3 lower ends, and the speed V that controls sand traps 5 by tether ring 4 reaches control sandblast rank.
Because the pipeline 1 of sand-spraying pot and required processing fuses, and advances with speed V in pipeline 1 so the pressure P 1 of sand-spraying pot just drives sand trap 5, the pipeline 1 at sand trap 5 rears just becomes sand-blasting machine sediment transport pipe.Sand grains collects for blast nozzle 3 by sand trap 5 and uses, and the abrasive material 6 that comes out through blast nozzle is scattering into a cone shape, has very high speed V sand and impacts inside pipe wall, because of sand grains has certain mass M, so have certain kinetic energy E=1/2MV sand
2, this kinetic energy is finished the cleaning of tube wall and is got the inner wall surface of certain anchor line degree, to improve coating bond area and adhesive power.
