Abstract

The utility model relates to an ironing machine drying drum with electromagnetic induction heating, which comprises an outer drum body, a rotating shaft, rotating wheels, an inner bracket and a frame, and is characterized in that one end of the outer drum body is provided with the rotating shaft, the other end thereof is opened, and the circumferential outer edge thereof is supported by at least three rotating wheels; the inner bracket extends into the outer drum body from the opening of the outer drum body, the outer side of the inner bracket is fixed on the frame, and the inner bracket is fixed with a plurality of induction coils which are arranged linearly; the outwards convex cambered surfaces of the induction coils are in coincidence with the inner wall of the outer drum body and have gaps; and the induction coils are connected with a high-frequency power supply. The ironing machine drying drum with electromagnetic induction heating is heated by induction current, and really realizes direct heating, fast heating, precise temperature control, high energy efficiency, simple drying drum structure and easy realization.

Description

The ironing machine drying cylinder of electromagnetic induction heating

Technical field

The utility model relates to a kind of ironing machine drying cylinder of ironing machine drying cylinder, particularly a kind of electromagnetic induction heating.

Background technology

Present known ironing machine electrical heating drying cylinder all adopts electrothermal tube to heat by medium, and medium mainly contains two kinds of conduction oil and air.

Adopt conduction oil to have characteristics such as thermic load is even, lasting, therefore obtain wider application as the ironing machine of the electrothermal tube heating drying cylinder of medium.But it has many deficiencies.One, huge thermal capacity cause reaching above preheating time of half an hour.Drying cylinder with 800 millimeters of diameters, 2500 millimeters of length calculates, and its conduction oil capacity is more than 1000 liters.Its two, big, the system complex of drying cylinder weight.Should leakproof, anti-overflow again.Also have, conduction oil is wanted oxidation deterioration, must regularly replace, and causes bigger follow-up expense; Though the conduction oil flash-point is higher, its inflammable characteristic is always arranged, there is certain potential safety hazard.

For remedying all deficiencies of conduction oil, arise with the drying cylinder of the direct hot type of electrothermal tube.This pattern is actually by a kind of mode of heating of air as medium, also is indirect.Because the air thermal conductivity factor is extremely low, electrothermal tube temperature not really high again (for radiant heat transfer) and radiant heat transfer is limited, therefore, the very fast advantage that it is simple in structure, with low cost of the wretched insufficiency that this pattern heat transfer efficiency is low is flooded, and adopts the ironing machine of this technology to tend to occur ironing speed low (production capacity is low) electrothermal tube again because of overheated tripping operation again and again.Therefore demand inventing a kind of novel ironing machine drying cylinder urgently.

Summary of the invention

The purpose of this utility model provides a kind of ironing machine drying cylinder that adopts electromagnetic induction heating technology, and this drying cylinder is faster under the induction of high frequency magnetic field, obtain heat more efficiently, thereby reaches the purpose of ironing machine ironing fabric.The ironing machine drying cylinder of the utility model electromagnetic induction heating technology, comprise outer cylinder body, rotating shaft, runner, inner support, frame, it is characterized in that: an end of outer cylinder body has rotating shaft, the other end is opening-like, on the circumferential outer edge of outer cylinder body, support by at least three runners, inner support is stretched in the outer cylinder body by the opening of outer cylinder body, the inner support outside is fixed on the frame, on inner support, be fixed with the induction coil that several lines are arranged, the outer convex globoidal of induction coil and outer cylinder body inwall coincide and are gapped, and induction coil connects high frequency electric source.The utility model has the advantages that drying cylinder is heated by induced-current, really realized direct heating, heating rapidly, temperature control is meticulous, energy efficiency is high, and drying cylinder is simple in structure, realizes easily.

Description of drawings

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the left view of the utility model Fig. 1.

Below in conjunction with drawings and Examples the utility model is elaborated,

Specific implementation method

Comprise outer cylinder body 1, rotating shaft 4, runner 6, inner support 2, frame 5 among the figure, it is characterized in that: an end of outer cylinder body 1 has rotating shaft 4, the other end is opening-like, on the circumferential outer edge of outer cylinder body 1, support by at least three runners 6, inner support 2 is stretched in the outer cylinder body 1 by the opening of outer cylinder body 1, inner support 2 outsides are fixed on the frame 5, on inner support 2, be fixed with the induction coil 3 that several lines are arranged, the outer convex globoidal of induction coil 3 and outer cylinder body 1 inwall coincide and are gapped, and induction coil connects high frequency electric source.

Place the high frequency electric source in the machine casing power frequency supply can be converted to the high frequency electric source of frequency up to 20-40kHz.Produce high frequency magnetic field when flowing through induction coil 3 from the high frequency electric source electric current, outer cylinder body 1 wall produces the rotatory current (eddy current) of many closures under the induction of high frequency magnetic field, and this electric current is (being equivalent to short circuit current) greatly, and embodies in the mode of heating; After outer cylinder body 1 rotates, obtain heat energy even, that continue at its circumferencial direction.

The utility model has the advantages that drying cylinder is heated by induced-current, really realized direct heating, heating rapidly, temperature control is meticulous, energy efficiency is high, and drying drum structure is simple, realizes easily.
