Cladding tube bank processing device
Technical Field
The invention relates to the technical field of deposited tube bank processing, in particular to a deposited tube bank processing device.
Background
The surface cladding process of the water wall tube bank is a new anti-abrasion measure which is widely accepted by the market at once in order to solve the problem of abrasion of the water wall of the coal-fired boiler, and the surface cladding process has the advantages of good effect, simple operation, low cost and the like, so that the surface cladding process is not only applied to the manufacture of a newly-built boiler, but also gradually applied to the updating and repairing of an old boiler. Therefore, the market supply pressure for welding the surface of the water wall tube bank is more urgent in recent years, and the developed automatic welding equipment for the water wall is more and more widely applied.
However, compared with manual welding gun welding, the automatic welding has high efficiency and good effect, but the defects of local welding, insufficient welding of a welded layer of a certain part and a welded material, and the like, of the tube bank are caused by the problems of equipment manufacturing precision, working abrasion, and the like, the local cold welding is difficult to find through the traditional methods of surface manual inspection, ray detection, and the like, and the hidden defects are often rapidly peeled off in the concrete use of the water wall and lose the protection effect on the pipeline of the water wall, so a device capable of applying proper external force to the welding surface to peel off the cold welding layer to expose is needed, and the welding quality of the welded tube bank is improved.
Meanwhile, the powder laser surface cladding process gradually becomes the mainstream due to good cladding effect and high speed, but the utilization rate of powder sprayed by powder laser cladding is low, non-cladding powder sprayed by a cladding head remains on a cladding pipe row, so that not only is the material wasted, but also the exposed powder can seriously pollute the environment, and the equipment also has the function of recycling redundant powder.
