Description

Reciprocating type electric heating tube contact rust cleaning device

Technical Field

The invention relates to the technical field of electric heating tube contact rust removal devices, in particular to a reciprocating type electric heating tube contact rust removal device.

Background

When the electric heating tube is used, because the electric heating tube is exposed in the air for a long time, the contact of the electric heating tube is easy to be oxidized, and oxide skin is generated on the surface, thereby reducing the heat transfer efficiency of the electric heating tube. Therefore, the scale on the surface of the electric heating tube needs to be removed when the scale reaches a certain thickness, and the service life of the electric heating tube is prolonged.

At present, the rust removal modes mainly comprise the following modes:

firstly, the method for derusting by sandblasting utilizes high-pressure air to spray quartz sand on the surface of a component for derusting, has lower cost and wide sources, but has great environmental pollution and larger noise during derusting. Workers need to automatically adjust the postures of the derusted parts during operation so as to remove rust uniformly, and the labor intensity of the workers is increased;

secondly, the chemical method for removing the rust comprises a nitric acid and hydrofluoric acid pickling method, an alkaline boiling-pickling composite method and the like, the scale is removed by chemical reaction between a chemical reagent and the scale on the surface of the part, more chemical reagents are used in the operation process, good ventilation conditions and good wastewater treatment conditions are needed, the operation process is dangerous, and the requirement on the operation level of an operator is high.

And thirdly, the steel brush removes rust, and the method drives the steel brush to rotate so that the steel wire continuously removes rust on the surface of the part to be polished. Little noise among the process of polishing, environmental pollution is little, the rust cleaning is respond well, by the surperficial rust cleaning of wide application in various parts, nevertheless the rust cleaning residue splashes easily, workman operational environment is abominable, current steel brush rust cleaning device has general polisher and special type polisher, general type polisher is mostly hand-held type and hand propelled polisher, special type polisher is mostly the section bar polisher, although the electric heating tube contact rust cleaning work can be accomplished to current general type steel brush rust cleaning device, it is even to need the workman to adjust by oneself the gesture messenger of the part of polishing, the operation is comparatively loaded down with trivial details, workman intensity of labour is great.

At present, the main technical problem is to reduce manual operation as much as possible, reduce labor intensity of workers and improve automation degree in the process of removing rust of the electric heating tube contact. On the other hand, the derusting process is uniform and has good derusting effect.
