Description
Technical Field
The invention belongs to the technical field of metal attachment removal, and particularly relates to metal attachment removal equipment based on electromagnetic induction and ultrasonic waves.
Background
In maintenance, various coatings such as paint, coating, rust layer, fireproof coating and the like on the surfaces of ship decks, ship hulls, grooves/cabinets/boxes for oil storage and gas storage in the petrochemical industry, offshore and land oil pipelines and the like are generally required to be removed.
Electromagnetic induction heating is a heating method in which electric energy is converted into magnetic energy, and a metal to be heated (such as a steel body) is heated by inducing the magnetic energy. The principle is that alternating current generated by an induction heating power supply generates an alternating magnetic field through an inductor coil, and magnetic conductive metal is arranged in the alternating magnetic field to cut alternating magnetic lines, so that alternating current, namely eddy current, is generated inside an object. The vortex makes atoms in the object move randomly at high speed, and the atoms collide and rub with each other to generate heat energy, so that the effect of heating the object is achieved. The principle of removing the attachments on the metal surface by electromagnetic induction is that the metal plate is heated by the electromagnetic induction heating technology, and the joint interface between the metal surface and the coating is damaged due to temperature difference, so that the purpose of removing the attachments on the metal surface is achieved. Patent EP2084939B briefly introduces this technique. Corresponding products have also been developed by foreign companies such as RPR Technologies.
When the existing electromagnetic induction equipment is used for removing metal attachments, cooperation of a plurality of persons is needed from the operation perspective, for example: one person operates the induction head of the electromagnetic induction device, and the other person holds a tool such as a shovel to remove the attachments on the heated metal surface. The reason why the tool such as a latte shovel removes the attachments on the metal surface is as follows: the electromagnetic induction heating only breaks the joint interface between the metal surface and the coating and does not completely peel off the attachment from the metal surface, so that the metal surface and the coating need to be completely peeled off by certain external force.
Ultrasonic waves are elastic mechanical waves propagating in a continuous medium, and the energy of the ultrasonic waves is mainly transmitted by the vibration of the elastic medium. Ultrasonic waves have found widespread use in industry, one of which is the descaling of heat exchanger tubes in boilers. The main principle is that the scale forming conditions are destroyed by a strong sound field, the deposition of the scale is prevented, and the scale is dispersed, crushed, loosened and is not easy to attach to the inner walls of the heat exchange tube and the shell to form scale.
The electromagnetic induction technology and the ultrasonic technology are combined to be used for removing the metal attachments, so that greater convenience and value can be brought.
