Description
Technical field
The present invention relates to a kind of utilize high voltage type strength to send sand horizontal shot blasting machine system and processing method, be applicable to carry out Shot Blasting to the tube wall of metal surface or steel pipe, be particularly useful for carrying out Shot Blasting to steel pipe inside and outside wall simultaneously, the steel pipe better processing effect of 600mm is particularly greater than for caliber, specifically, relate to a kind of for the horizontal shot blasting machine system of tube wall surface process and Shot Blasting method, belong to steel pipe processing technology field.
Background technology
Steel pipe is widely applied to water supply field, and in order to extend the service life of steel pipe, preservative treatment is extremely important.
At present, more advanced a kind of anti-corrosion measure carries out plastic-coated process at steel pipe inside and outside wall exactly, needed to eliminate rust to the inside and outside wall of steel pipe before plastic-coated, due to pickling, the rust cleaning such as phosphatization mode environmental pollution is serious, and the steel pipe walls smoother after pickling, reduce the adhesive force of coating layer in steel pipe walls, so current before carrying out plastic-coated to steel pipe inside and outside wall, when needing to carry out processing of rust removing to steel pipe inside and outside wall, preferably the mode of eliminating rust is impeller blasting, be on the one hand because impeller blasting process can not to environment, but because in the process to steel pipe inside and outside wall impeller blasting, the roughness on steel pipe walls surface can be increased, thus strengthen coating layer to the adhesive force of steel pipe walls.
According to current impeller blasting technique, to eliminate rust to the inside and outside wall of steel pipe, usually need to adopt the shot-blasting machine equipment eliminated rust separately to the inside and outside wall of steel pipe respectively, respectively impeller blasting operation is carried out to the inside and outside wall of steel pipe, inwall descaling process generally needs 40 minutes, outer wall descaling process also needs 40 minutes, and the rust cleaning time is long, and efficiency is low.
In addition, although carry out the Technical comparing maturation of impeller blasting in the market to the outer wall of steel pipe, for not perfect to the technology of steel pipe inner wall impeller blasting.
Existing steel pipe inner wall Shot Blasting equipment, in order to reduce the size of peener to be applicable to the small-bore steel pipe inner wall of process, usual employing motor driven liquid pressure station, Hydraulic Station drives the power transmission pattern of fluid motor-driven ball blast head, and due in ball blast process, steel pipe horizontal positioned, in order to the sand of dishing out ball is taken out of from the powerful air-flow of steel duct, just need powerful ventilation and dust removal equipment, so the mostly bulky needs of existing steel pipe inner wall shot-blast apparatus take larger hall space, and energy consumption height rust cleaning efficiency is low.Especially for bigbore steel pipe, existing horizontal steel pipe inner wall shot-blasting machine is in the process of carrying out inwall impeller blasting, and the sand ball when caliber is larger in pipe is timely Automatic clearance in ball blast process not easily, affects recycling of Shot Blasting efficiency and sand ball.
At present for steel pipe inner wall Shot Blasting shot blasting machine, need steel pipe horizontal positioned in ball blast process, now in order to the sand of dishing out ball is taken out of from the powerful air-flow of steel duct, just need powerful ventilation and dust removal equipment, and supply sand system to be all first sand ball is risen to certain altitude, then sand ball relies on self gravitation to slip down to on sand belt along sand-guiding tube, dished out to ball blast head inside by Belt Conveying again, so existing steel pipe inner wall shot-blast apparatus is mostly bulky, complex structure, need to take larger hall space, and fault rate height rust cleaning efficiency is low.Especially for bigbore steel pipe, existing horizontal steel pipe inner wall shot-blasting machine in the process of carrying out inwall impeller blasting, the sand ball in pipe not easily in ball blast process by the timely Automatic clearance of exhaust equipment, affect recycling of Shot Blasting efficiency and sand ball.
A kind of structure of the peener for steel pipe inner wall process disclosed in patent CN200820222304 as depicted in figs. 1 and 2, mainly comprise fixed frame 1, regulate the parts such as frame 2, sediment transport belt rod 3, ball blast head 4, belt pulley 5, interior sanding arm 6, as can be seen from Figure 1 the peener complex structure of this structure, and fault rate is high in use procedure, in addition, also need not stopped to rotate by the steel pipe eliminated rust in ball blast process, thus cause ball blast efficiency low, the problem of rust cleaning weak effect.Ball blast header structure wherein as shown in Figure 2, ball blast head rotates in the horizontal plane of steel pipe inner wall along steel pipe axis, the ball blast head that rust cleaning sand ball sends into horizontal positioned by belt for sand device above ball blast head is inner, ball blast head lobe sheet is distributed to by pills dispensing apparatus and a point ball hole, to be dished out at a high speed from ball blast head side impact steel pipe inner wall by blade, thus reach the object to steel pipe inner wall processing of rust removing.
