Description
Technical field
The present invention relates to a kind of device and method that equipment inner surface is eliminated rust, relate in particular to a kind of inner bag light decorations rust removalling equipment and derusting method thereof to the rust cleaning of space flight air-channel system bottle inner surface.
Background technology
At present, in space flight air-channel system, the rust cleaning of gas cylinder bottle inner surface is the technical barrier of puzzlement this area always, and special-shaped bottle inner surface rust cleaning especially in irregular shape is not easy to operate especially.In prior art, derusting method is mainly sandblast and pickling, but above method all has its limitation, the sandblast of bottle inner bag, easily there is blind area, the problem that causes corrosion place to remove, pickling limits by technique for Qiang Gangwei, in Aeronautics and Astronautics enterprise, bans use of.
Tumbling is that part is put into the cylinder that fills abrasive material and chemical solution, and drum rotating makes part and abrasive material, part and the mutual friction of part phase reach the process of cleaning piece surface.Tumbling is carried out for part outer surface, for bottle inner surface, not yet uses.
Inner surface rust cleaning all the time is often substituted by pickling, so tumbling is never incorporated in bottle inner surface rust cleaning field.But along with high-strength steel is used in a large number in product, this problem of hydrogen embrittlement that easily causes of pickling manifests gradually.Rolling finishing technology is introduced bottle inner surface and also under specific environment, is derived.
Rolling finishing technology is processed bottle inner surface technical barrier: abrasive material and the kind of mill liquid and the difficult problem that proportioning is this technology.When abrasive material overcharge swings, impact stroke will shorten affects ground effect, and very few impact strength is inadequate again.Mill liquid kind can have multiple, if but select neutrality or weak acidic medium, because bottle inner surface is through light decorations (activating surface), easily produces at short notice floating rust and cause anticaustic; If select not easy cleaning of alkaline medium excessive concentration inner surface, concentration is too low does not have again the effect of process corrosion-resistant, and the selection of therefore grinding liquid is particularly important.Above 2 is also that restriction tumbling is in the reason of inner surface application.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of inner bag light decorations rust removalling equipment is provided, solved in prior art the bottle inner surface difficult problem that eliminates rust.
Another object of the present invention is to provide a kind of derusting method of inner bag light decorations rust removalling equipment.
Technical scheme of the present invention is as follows:
Mounted motor I on pedestal, motor I is by transmission device I connecting platform, and platform is provided with motor II, and motor II connects bottle by transmission device II, and the top of platform is provided with for the fixing fixed mount of bottle.

Described platform is provided with balancing weight.
Described transmission device II is chain.
Described fixed mount consists of chuck and tail top.
Derusting method of the present invention comprises the steps:
By in-built high-hardness grinding material and the mill liquid filled out of pending bottle, utilize tail top and chuck bottle to be installed fixing; During motor II work, by chain-driving bottle, carry out rotation; Abrasive material in bottle produces relative motion under the effect of gravity and body rotation, thereby plays the effect of cutting surface; When motor I is rotated, by eccentric wheel rocking arm band moving platform, produced and swung up and down, thereby drive bottle to swing, the abrasive material in bottle also produces relative motion thereupon, and now before and after bottle, end socket place will be subject to the impact of abrasive material; The comprehensive kinetic energy that swings abrasive material generation, impacts oxide layer and the iron rust of bottle inner surface, thereby reaches the effect of clean bottle inner surface.
During the work of described abrasive material, injected volume and the bottle ratio of weight and number that holds amount of abrasive of buying securities with all one's capital is 1:2.
Described abrasive material comprises φ 6 corundum ball material and length of side 4mm corundum corner material, and the ratio of weight and number of φ 6 corundum ball material and length of side 4mm corundum corner material is, φ 6 corundum ball material: length of side 4mm corundum corner material=2:1.
Described mill liquid and the ratio of weight and number of abrasive material are 1:2.
Described mill liquid comprises sodium nitrite solution and sodium carbonate liquor, and the concentration of sodium nitrite solution is (10～20) g/L, and the concentration of sodium carbonate liquor is (1～2) g/L.
Advantageous effect of the present invention is as follows:
Adopt light decorations rust cleaning technology, thereby by abrasive material and bottle grinding internal surface, reach the effect of rust cleaning, not only effectively removed the corrosion thing in bottle inner surface cavity, the hydrogen embrittlement problem of having avoided again pickling to cause, and the local corrosion that sandblast exists clears up problem not in place, for bottle inner surface, rust cleaning has stronger generalization.This technology there is no similar research in this area, for cavity inner surface, rust cleaning has very important value.
