A racetrack-shaped close-wound electromagnetic inductor

Abstract

The invention relates to the technical field of tank body weld joints, in particular to a track type close-wound type electromagnetic inductor. The track type close-wound electromagnetic inductor mainly comprises a support, magnetic core sets, a wire and a power source. Each magnetic core set is formed by arranging U-shaped magnetic cores. A spacing block is arranged between every two magnetic core sets. Due to the spacing blocks, mutual interference between the magnetic core sets is effectively avoided. Magnetic core feet on one sides of the U-shaped magnetic cores are surrounded together through the wire. The two ends of the wire are connected with the power source and are wound around the magnetic core feet by at least one circle. The power source for rectifying and inverting current is used for electrifying the wire. A magnetic induction loop is formed by the two magnetic core feet of the same U-shaped magnetic core. By means of the electromagnetic inductor, heating is environment-friendly, energy conservation is achieved, the automation degree is high, compared with the manner that a traditional heating area is only concentrated in the middle and the peripheral heating effect on the front end and the rear end is extremely poor, the track type close-wound type electromagnetic inductor has the beneficial effects that due to the application of the electromagnetic inductor, the heating area is wider, the drying effect of the front end and the rear end of a tank body is improved, the heat efficiency is greatly improved, the production efficiency of products is improved, a magnetic loop is shortest and most concentrated, and environment radiation is reduced.

Description

technical field [0001] The invention relates to the technical field of tank body welds, in particular to a racetrack-shaped close-wound electromagnetic inductor. Background technique [0002] In recent years, with the development and improvement of the performance of electronic components, the performance of electromagnetic induction heating equipment has been continuously improved, and more and more people have paid more and more attention to it, especially in the canning industry. The frequency range works in the range of ultra-audio frequency 20KHz~150KHz (super-audio frequency 22KHz), and is more and more used in drying, heating and curing equipment to form electromagnetic induction heating and solid induction heating to dry and cure protective coatings and sealants. . [0003] At present, the medium-frequency induction equipment for welding seam repair can basically be summarized into two types of inductor structures, which are U-shaped tube inductors and pancake-shape...

Problems solved by technology

The magnetic field is uneven, and continuous uneven heating is generated when the tank moves, and the thermal efficiency is low. The direction of the magnetic field is also uncontrollable, and the protection is difficult. Moreover, the alternating electromagnetic field generated when the induction heating equipment is working releases electromagnetic waves to the surrounding environment to generate electromagnetic radiation. Long-term, excessive Electromagnetic radiation can cause harm to human health
