Some nozzles 8 that ejection head unit comprises fixture 9 and is uniformly distributed on fixture 9 periphery, angle between each nozzle 8 and the axis of fixture 9 is 70 °, it should be noted that, what the angle between nozzle and fixture axis was common is 90 degree of vertical direction, now current and steel pipe inner wall are 90 degree, current are large to steel pipe inner wall active force, but current can rebound by former direction after encountering steel pipe inner wall, cause current utilization rate not high.When forming an angle, current resolve into horizontal and vertical directions and act on steel pipe inner wall, the current of horizontal force carry out axial flushing to steel pipe inner wall, ratio only have better developing result with vertical direction current, as calculated and put into practice (when the nozzle 8 described in the present embodiment and the angle between the axis of fixture 9 are 70 °) current become 20 degree of angles during with vertical steel tube inwall direction, best developing result can be obtained.
Rotating shaft 4 be provided with the water transport channel be communicated with nozzle 8 in fixture 9; Be provided with water-injecting cavity in casing 12, water-injecting cavity is communicated with water transport channel, and water-injecting cavity is communicated with high-pressure intake pipe 13.In the present embodiment, rotating shaft 4 is provided with two intake tunnels, two intake tunnels all through and perpendicular to the axis of rotating shaft 4, and intake tunnel runs through the sidewall of rotating shaft 4, mutually vertical between two intake tunnels.During work, high-pressure intake pipe 13 is injected into the flushing water of water-injecting cavity, enters into water transport channel by intake tunnel, and by water transport channel by flushing water supply nozzle 8, finally makes flushing water spray from nozzle 8.Arrange two intake tunnels, make rotating shaft 4 forms four water inlets, when it rotates, the frequency that flushing water can be made to inject is higher, prevents when injecting flushing water to nozzle 8, occurs the situation of cutting off the water supply.
Also be provided with two bearing 2 chambeies in casing 12, two bearing 2 chambeies, respectively along the both sides being axially set in water-injecting cavity of casing 12, are respectively equipped with rotatory sealing 3 between water-injecting cavity and bearing 2 chamber.Bearing 2 is respectively equipped with bearing 2 in chamber, and bearing 2 and casing 12 are all coaxially arranged, and rotating shaft 4 is each passed through bearing 2, and bearing 2 is all for supporting rotating shaft 4.The two ends of rotating shaft 4 are also arranged with stop nut 5 respectively, and stop nut 5 is for carrying out axial limiting to bearing 2, and stop nut 5 is arranged at outside bearing 2, and specifically, stop nut 5 is arranged between bearing 2 and two bottom surfaces of casing 12.In the present embodiment, bearing 2 is taper roll bearing, and two described taper roll bearings are arranged dorsad, heavier compound (radial and axial) load can be born, rigidity is strong, and can axial restraint in both direction, with certain end-play or certain preload.
As shown in Figure 2, the end of expanding machine afterflush cantilever 17 is provided with sleeve 16, and casing 12 is fixed on sleeve 16 by adpting flange 15.
Driver element in the present embodiment is air motor 1, air motor 1 is minitype pneumatic motor, there is the advantage that structure is simple, the range of speeds is wider and be not subject to high temperature and vibration effect, application in the present embodiment, the structure of the present embodiment can be simplified, even if also work can be carried out well under the comparatively slow-speed of revolution.
Expanding machine afterflush cantilever 17 and sleeve 16 are hollow structure, expanding machine afterflush cantilever 17 inside is provided with high-pressure intake pipe 13 and motor air supply pipe 18, coaxially in sleeve be provided with air motor 1, the output shaft of air motor 1 is connected with rotating shaft 4 through after casing 12; One end of motor air supply pipe 18 through expanding machine afterflush cantilever 17 and sleeve 16, and is communicated with air motor 1, and the other end is communicated with magnetic valve, the break-make of solenoid control motor air supply pipe 18, thus whether control air motor 1 rotates; The sidewall of sleeve 16 offers through hole, and high-pressure intake pipe 13 penetrates sleeve 16, and stretches out from through hole, is finally communicated with water-injecting cavity.
In the present embodiment, casing 12 is the tubular structures of two ends without bottom surface, and the bottom surface, one end of casing 12 is coated with base plate 14, and other end bottom surface is provided with end cap 6, also be provided with two-layer dividing plate in casing 12, casing 12 is divided into two bearing bores and a water-injecting cavity by base plate 14, end cap 16, dividing plate; Rotating shaft 4 is through end cap 6 and two-layer dividing plate, and rotatory sealing 3 is arranged between dividing plate and rotating shaft 4 respectively, thus seals between water-injecting cavity and bearing bore, prevents flushing water from revealing.The slip ring that rotatory sealing 3 is made up of a filled polytetrafluoroethylene and one provide the rubber o-ring of elastic force to form, and can bear the two-way function of pressure at both sides or alternating pressure effect, when rotating shaft 4 rotates, still can reach good sealing effectiveness.
The output shaft of air motor 1 is connected with rotating shaft 4 through after base plate 14; Base plate 14, be respectively equipped with O RunddichtringO between end cap 6 and casing 12, be provided with outside framework oil seal between end cap 6 and rotating shaft 4, outside framework oil seal carries out axial limiting by back-up ring 10.O RunddichtringO and outside framework oil seal all play the effect of waterproof sealing.
The specific works flow process of the present embodiment is as follows:
Steel pipe after expanding is transported to afterflush station by pipe carrying truck, afterflush station rollgang starts, before steel pipe market to flusher, after detection signal detects steel pipe, flush signal is sent by control system, then high-pressure hydraulic pump water delivery air motor ventilation simultaneously, makes rotating shaft 4 drive ejection head unit to start churning and goes out rinse water, and steel pipe moves on until whole steel pipe completes once flushing through expanding machine afterflush cantilever 17 simultaneously.After steel pipe advance puts in place, steel pipe is exited in rollgang reversion, and ejection head unit continues to keep rotary water jet, and after steel pipe exits expanding machine afterflush cantilever 17, air motor stops the rotation, and high-pressure hydraulic pump stops water supply, completes secondary cleaning.
In sum, the present embodiment is transformed Flushing nozzle version of the prior art, the nozzle 8 making to fix by installing air motor additional becomes 360 degree of circumference and rotates, flushing scope is made to reach steel pipe inner wall all standing, thus eliminate flushing dead angle, steel pipe inner wall developing result is greatly improved.Simultaneously because spin rinse water use efficiency is high, flush water pump flow is kept to original 1/5th can meet rinsing requirement, replaceable flush water pump is low discharge water pump, by water yield be 42 vertical/hour, power be the flush water pump of 37KW change into water yield be 8 vertical/hour, power is the flush water pump of 30KW, reaches the effect that developing result is well energy-conservation again.The use of low power flush water pump, also makes the expanding water treatment station process water yield diminish, water quality treatment is protected.
Embodiment of the present utility model provides for the purpose of example and description, and is not exhaustively or by the utility model be limited to disclosed form.Many modifications and variations are apparent for the ordinary skill in the art.Selecting and describing embodiment is in order to principle of the present utility model and practical application are better described, and enables those of ordinary skill in the art understand the utility model thus design the various embodiments with various amendment being suitable for special-purpose.
