[ detailed description ] embodiments
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a heating pipe for an electromagnetic hot-blast stove, which comprises:
the pipe body is provided with an inner cavity penetrating through two ends, and the pipe body is specifically an iron pipe containing iron.
The first heat exchange fin group comprises a plurality of first heat exchange fins 1, and the plurality of first heat exchange fins 1 are uniformly distributed on the wall of the inner cavity in the circumferential direction;
the second heat exchange fin group is arranged in front of or behind the first heat exchange fin group and comprises a plurality of second heat exchange fins 2, and the plurality of second heat exchange fins 2 are uniformly distributed on the cavity wall of the inner cavity in the circumferential direction;
first heat transfer fin 1 and second heat transfer fin 2 dislocation set, when air or wind pass through the inner chamber, for example earlier through first heat transfer fin 1's region, because first heat transfer fin 1 and second heat transfer fin 2 dislocation set, therefore when wind contact second heat transfer fin 2, wind can be cut apart by second heat transfer fin 2, through the wind of second heat transfer fin 2 reheating process, make more even quilt of wind heat exchange efficiency.
In this embodiment, first heat transfer fin 1 and second heat transfer fin 2 all weld on the chamber wall of inner chamber, strengthen the compactness of first heat transfer fin 1 and second heat transfer fin 2 and chamber wall, improve heat conduction efficiency.
The number of the first heat exchange fins 1 is consistent with that of the second heat exchange fins 2, so that the first heat exchange fins 1 and the second heat exchange fins 2 are more uniformly distributed, and each second heat exchange fin 2 can separate wind conveyed from the first heat exchange fins 1, and further the heat exchange efficiency is enhanced.
The pipe shaft includes first pipe portion 3 and second pipe portion 4, first heat transfer fin group sets up in first pipe portion 3, second heat transfer fin group sets up in second pipe portion 4, and first pipe portion 3 and second pipe portion 4 can also be the return bend for the straight tube, when two pipe portions are the straight tube, only need one of them pipe portion of fixing, for example fixed first pipe portion 3, then rotate second pipe portion 4, make second heat transfer fin 2 in second pipe portion 4 and the heat transfer fin 1 dislocation back in the first pipe portion 3, weld first pipe portion 3 and second pipe portion 4 can, convenient equipment to can carry out length according to the customer's demand and order.
The heating pipe still includes heat preservation fire-resistant cotton 5 and coil 6, the outer wall setting of heat preservation fire-resistant cotton 5 cover pipe shaft, coil 6 encircles the outer wall setting of heat preservation fire-resistant cotton 5, heats the pipe shaft after the coil circular telegram, heats the pipe shaft with electromagnetic heating's mode promptly, and electromagnetic heating's rate of heating is fast, and the heat loss is few, will be more energy-conserving high-efficient than traditional resistance heating.
In addition to the above embodiments, the present invention can also have other embodiments, and the technical solutions formed by equivalent replacement or equivalent transformation are adopted and all fall within the protection scope of the present invention.
