Description
Technical field
The invention belongs to field of surface engineering technique, and in particular to a kind of narrow gap deep hole pipe fitting dust-free blasting mechanism.
Background technology
Power system device exist it is substantial amounts of it is through walls run through pipe fitting, when there is Korrosionsmedium, such as Cl- in atmospheric environment,
Its pipeline and internal weld seams are often corroded, under shock effect, and this chemical attack will develop into stress corrosion fatigue, sternly
Cause weld cracking in the case of weight, vibrations aggravation endangers piece safety.This phenomenon is especially prominent in nuclear power station.In unit peace
During dress, by factory's progress spray painting protection, Assembling, after long service, surfacecti proteon enamelled coating comes off, and occurs rotten
Erosion.Spray painting protection during different from units' installation, protected working now first must remove corrosion layer, and ensure that surface is clear
Cleanliness and roughness reach standard setting, then anticorrosion with painting erosion resisting coating.After installation, gap is narrow, and minimum clearance only has
30mm, and through pipe fitting depth up to 1100mm, in this case, traditional derusting method is it cannot be guaranteed that table to be sprayed after derusting
The cleannes and roughness in face.
Removal for corrosion layer at present generally has two methods of mechanical grinding and traditional sandblasting.Mechanical rubbing method is to adopt
Corrosion resistant coating is polished with electronic or Pneumatic angle grinder and removed, surface smoothness that this method is polished, uniformity, cleannes
It is poor, the removal of surface quality requirements higher part part corrosion layer is not suitable for, less suitable for narrow gap, deep hole, small
The removal of the component corrosion layer of regional characteristics.
Traditional blasting method the sand grains of high rigidity is ejected into workpiece surface i.e. using sand-blasting machine and compressed air so that
The method that corrosion layer comes off.Sprayed for there is the place that dust concentration limitation is required generally to use from recovery sand blasting unit
Sand, but it is commonly available to more smooth, sand blasted area larger due to being limited by own vol and structure from sand blasting unit is reclaimed
Part sandblasting.And reach 1100mm for depth, gap only only has 30-150mm components interior sandblasting work, it is this from
Retracting device is unavailable.
Be up to state standards requirement for the sandblasting quality realized in deep hole, narrow gap, and meet dust-free blasting requirement, it is necessary to
A kind of special sand blasting unit.

One end of second poly (methyl methacrylate) plate 10 of first poly (methyl methacrylate) plate 7 of described two semi-annular shapes away from semi-annular shape
It is provided with rubber blanket 24.
The thickness of the rubber blanket 24 is 3-5mm.
The thickness of first poly (methyl methacrylate) plate 7 of described two semi-annular shapes and the second poly (methyl methacrylate) plate 10 of two semi-annular shapes
Spend for 10-20mm.
A diameter of 10-15mm of the roller 23, described 25 compressible stroke is 5-10mm.
Using during described device by being installed on the butterfly nut 19 and slip-knot spiral shell of I-shaped semicircular ring double-decker one end
Bolt 18 is fixed, and is installed in intermediate conduit, can pass through the adjusting elasticity of butterfly nut 19.
Compared to the prior art, the invention has the advantages that：
1) dust sealing is carried out by I-shaped semicircular ring double-decker, I-shaped semicircular ring double-decker by hinge and
Butterfly nut is fixed, easy for installation, fast.Realize the sandblasting of deep hole narrow gap pipe fitting, spraying process no dust pollution.
2) organic plates are employed as apparatus main body material, make observable in sandblasting procedures treat sandblasting position situation and
Whether sandblasting in place, prevents from causing sandblasting by mistake because that can not observe.
3) the smooth movement of spray gun in sandblasting procedures is realized by bottom roller, prevents movement from not causing freely local sandblasting strong
Height is spent, causes parts metals body to penetrate, prevents from causing central tube damage.
4) sand grains and dust is avoided to escape and damage roller by rubber blanket.
