Autoclave belongs to pressurized vessel, this device fabrication requires to remove welding stress, in existing technical scheme, it is to adopt thermal life to process that the destressing of the kettle of autoclave is processed, but the kettle of autoclave is large-scale workpiece, length has tens of rice, weight has tens of tons, and sometimes also need to carry out assembly welding at the delivery scene, if kettle adopts thermal life to process, not only need to build large-scale thermal life stove, and the expense that thermal life is processed is also very high, the kettle of this external delivery site welding technology, some situation also can't carry out the overall thermal ageing treatment.
Therefore, if the kettle of autoclave is carried out the thermal life processing, certainly exist the difficult problem that the timeliness facility investment is large, the timeliness cost is high and can't process delivery site welding technology kettle.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of autoclave kettle vibration ageing device, and this vibration ageing device can solve existing kettle and adopt thermal life can cause that the timeliness facility investment is large, the timeliness cost is high and the equipment erecting stage is difficult to the problem that adopts thermal life to process.
The technical scheme that the utility model technical solution problem adopts is: this autoclave kettle vibration ageing device, include vibrator, there are two otic placodes that stretch out to the side described vibrator lower end, be equipped with arc caliper on two otic placodes of described vibrator, described caliper upper end is coated with screw rod by screw thread; Be provided with upper padding plate and lower bolster between the placement bottom surface of described otic placode and the clamping face of described caliper.
In above-mentioned autoclave kettle vibration ageing device technical scheme, technical scheme can also be more specifically: the bottom surface of described upper padding plate is convex arc surface; The end face of described lower bolster is concaved circular cambered surface.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, owing to being provided with at kettle round flange inner tube wall the upper padding plate that the bottom surface is convex arc surface, being provided with end face at the corresponding round flange wall of the outer-rotor of upper padding plate is the concaved circular cambered surface lower bolster, on these two, lower bolster, just consist of one and had the parallel clamping face in two sides, by caliper, vibrator is rigidly fixed in round flange inner tube wall place, in the oscillating aging treating processes, vibrator can not become flexible, the parameter stabilities such as the rotating speed of oscillating aging equipment and acceleration, can reach best effect of vibration stress relief, can eliminate the welding residual stress of kettle effective and rapidly, realized the application of vibration aging technology on kettle, can be the thermal life cost 98% of autoclave kettle, the thermal life facility investment reduces by 80%.
2, due to can be autoclave kettle vibration ageing device, be transported to the delivery assembly welding on-the-spot, kettle to site welding technology carries out the oscillating aging processing, therefore, can solve existing kettle adopts thermal life can cause that the timeliness facility investment is large, the timeliness cost is high and the equipment erecting stage is difficult to the problem that adopts thermal life to process.
3, agree through designing unit and supervision and inspection institute, adopting the utility model to carry out oscillating aging to 100 kettlies processes, and carried out the follow-up investigations of 2 years, do not found that all weld seam between weld seam, cylindrical shell and the bearing between cylindrical shell and round flange cracks the phenomenon with round flange generation ovalizing deflection.
