Abstract
The utility model discloses a centrifugal type turbo-expansion injection for an anticorrosion spray coating equipment in a metal pipe. The utility model is characterized in that the injection adopts a centrifugal type expanding nozzle and a squirrel injection. The utility model is characterized in that the injection adopts the centrifugal type expanding nozzle and a squirrel-cage turbo vane cascade structure; the centrifugal type turbo-expansion injection can uniformly spray coating without rotating a pipe during the anticorrosion spray coating process in the metal pipe; as a consequence, the centrifugal type turbo-expansion injection reduces more rotating apparatus, and simultaneously, the injection also solve the difficult problem of repaired mouth of craters of welding pipelines. The utility model has the advantages of simple structure and easy operation, and the utility model is flexible and reliable, etc. The injection is adapted for anticorrosion spray coating in various pipes, in particular that the injection is adapted for inner anticorrosion spray coating operation of a screwed pipe, and the injection can be used for cleaning working of inside of pipes and cylindrical vessels.
Description
The utility model relates to a kind of centrifugal turbine expansion-injection device that is used for anti-corrosion spray device in the metal tube.
Along with development of industry and agriculture, the various metal pipes of requirement of engineering such as oil field, building, chemical industry, water treatment are imbedded underground, since the influence of various factors, the inside and outside seriously corroded of metal pipe, shorten service life, and the annual loss that subscription rate causes owing to corrode is very surprising.In order to solve the interior anticorrosion problem of metal pipe, general both at home and abroad at present spraying liquid coating and the organic and inorganic anticorrosion powder of adopting is as corrosion resistant coating, epoxy resin powder, the thermal spraying of metal powder etc.More than the nozzle structure of employed spray equipment different, but generally all be fixed porous direct projection structure, be exactly this structure as the employed shower nozzle of spray epoxy powder of China National Petroleum Corporation's Tianjin construction technology Research Institute.Because these shower nozzles are fixed porous direct projection structure, spray evenly, metal pipe is constantly rotated, a cover rotating machinery so just must be arranged.If caliber is bigger, rotating machinery is also bigger, also just needs larger area industrial premises and floor space, invests also more.On the other hand, because necessary turne tube during spraying, so in the site operation, the anticorrosion of weld bond place just can't solve during welded pipeline, because the coating of shower nozzle ejection is to penetrate on tube wall along the certain angle rectilinear direction,, just be easy to generate leak source simultaneously if tube wall has concavo-convex or spot, very little leak source can make and contain electrolytical medium local corrosion aggravation, spot corrosion or perforation occur.
The purpose of this utility model is exactly to make a kind of new shower nozzle, and it needn't just can be sprayed evenly by turne tube in spraying process.Not only adapt to the interior anticorrosion of general pipe and container, be more suitable for screwed pipe and pipe interior anticorrosion of spot arranged, can also solve the repaired mouth problem of present insurmountable on-the-spot welded pipeline simultaneously.
Fig. 1 is the structure chart of centrifugal turbine expansion-injection device.
Fig. 2 is the A-A profile of centrifugal turbine expansion-injection device.
The utility model is by ejectisome 1, expanding nozzle 2, bearing 3, turbine as illustrated in fig. 1 and 2 Leaf grating 4 and grid seat 5 form. A uniform 6-20 expanding nozzle 2 on the circumference of ejectisome 1, leaf grating seat 5, ejectisome 1 are combined into one with bearing 3. Turbine cascade 4 is mouse cage type structure, is fixed on the leaf grating seat 5 and with expanding nozzle and matches.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.In carrying out steel pipe during anti-corrosion spray, centrifugal turbine expansion-injection device is installed on the corollary equipment, stretch in the steel pipe that is sprayed, compressed air with air compressor, coating is transported in the injector by interior steel pipe from loader, mix with air again through expanding nozzle 2 and produce high-speed fluid ejection to turbine cascade 4, at this moment Pen Chu fluid is broken down into two kinds of power, it is radial load and perpendicular to the tangential force of radial load, promote turbine cascade 4 by tangential force and carry out circular motion, the medium (coating) that radial load is taken fluid is ejected into and forms the anticorrosive coat that needs thickness on the steel pipe inwall.At this moment, what coating sprayed under the action of centrifugal force of the leaf grating of high speed rotating is a parabola uniformly, and each position of tube wall can both injectedly equably be coated.Coating thickness is controlled with the speed of travel of adjusting spray equipment.
Major advantage of the present utility model is:
1, the utility model has adopted centrifugal expanding nozzle and mouse to penetrate the device structure, in the interior anti-corrosion spray of metal pipe, the leaf grating high speed rotating forms the jet face of a parabolical, not needing pipe just to rotate can spray, thereby has reduced more rotating machinery, has simplified technology, floor space and industrial premises have been reduced, saved investment, reduced cost, remarkable in economical benefits.
2, because the coating of centrifugal turbine expansion-injection device ejection is the jet face of a parabolical, spraying evenly, can both all spray coating for concavo-convex equably with spot and small gap place, not only be fit to the interior anticorrosion of general pipe, solve the interior anticorrosion problem of screw thread pipe simultaneously, improved coating quality.
3, because the utility model spraying the time does not need pipe to rotate, thus at the scene in the construction filling spray of pipeline weld bond be coated with technology and be achieved, solved long-term indeterminable repaired mouth problem.
4, use the utility model can also carry out pipe and small-sized cylindrical chamber cleaning.
5, the utility model is simple in structure, flexibility and reliability, easy operating.
