Description
Technical field
The utility model relates to a kind of heating furnace, relates in particular to a kind of high-frequency induction formula holding furnace.
Background technology
Holding furnace is widely used in chemical fibre industry, be mainly used in the spinneret in chemical fiber machinery, fondant filter, cross the stove that the parts such as element kit are heat-treated, after spinneret etc. is heat-treated, then spinneret is used for spraying silk, sprays a technique.Existing holding furnace in use, the radio-frequency induction coil that is wrapped in polymer thermal insulative cotton outside easily comes off with overlapping, there is no good fixture, if radio-frequency induction coil comes off or can cause the poor temperature uniformity in body of heater when overlapping, can make the spinneret that is heat-treated or filament spinning component etc., in spinning process, produce serious waste silk phenomenon.
Utility model content
Technical problem to be solved in the utility model is: the high-frequency induction formula holding furnace that a kind of temperature homogeneity is good is provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: high-frequency induction formula holding furnace, comprise: body of heater and the high frequency switch board that is arranged on body of heater one side, in described body of heater, be provided with burner hearth, in the upper end of described burner hearth, be provided with the bell of its folding relatively, on described bell, be provided with handle, in the bottom of described burner hearth and the lid of bell, be provided with insulation material, in the outside of described burner hearth, be enclosed with polymer thermal insulative cotton, in the outside of described polymer thermal insulative cotton, be evenly provided with some radio-frequency induction coil fixed heads, the two ends up and down of described radio-frequency induction coil fixed head are fixed by screws on body of heater, on the inner side of described radio-frequency induction coil fixed head and the outside of polymer thermal insulative cotton, be respectively arranged with some semi-circular recesses, in the cavity forming at described two corresponding semi-circular recesses, be wound with radio-frequency induction coil, described radio-frequency induction coil is connected with high-frequency and high-voltage power supply by high frequency switch board.
In order to solve the problems of the technologies described above better, the further technical scheme that the utility model adopts is: in the outside of described polymer thermal insulative cotton, be evenly provided with eight radio-frequency induction coil fixed heads.
The utility model has the advantages that: above-mentioned high-frequency induction formula holding furnace, by being wound around radio-frequency induction coil in the cavity forming at two corresponding semi-circular recesses, can effectively prevent that radio-frequency induction coil from coming off or overlapping, temperature homogeneity is good, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high-frequency induction formula holding furnace.
Fig. 2 is the cross-sectional view of A-A in Fig. 1.
In figure: 1, body of heater, 2, high frequency switch board, 3, burner hearth, 4, bell, 5, handle, 6, insulation material, 7, polymer thermal insulative is cotton, 8, radio-frequency induction coil fixed head, 9, screw, 10, semi-circular recesses, 11, radio-frequency induction coil.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, describe in detail particular content of the present utility model.
As Fig. 1, shown in Fig. 2, high-frequency induction formula holding furnace, comprise: body of heater 1 and the high frequency switch board 2 that is arranged on body of heater 1 one sides, in described body of heater 1, be provided with burner hearth 3, in the upper end of described burner hearth 3, be provided with the bell 4 of its folding relatively, on described bell 4, be provided with handle 5, in the bottom of described burner hearth 3 and the lid of bell 3, be provided with insulation material 6, in the outside of described burner hearth 3, be enclosed with polymer thermal insulative cotton 7, arranged outside in described polymer thermal insulative cotton 7 has some radio-frequency induction coil fixed heads 8, the two ends up and down of described radio-frequency induction coil fixed head 8 are fixed on body of heater 1 by screw 9, on the inner side of described radio-frequency induction coil fixed head 8 and the outside of polymer thermal insulative cotton 7, be respectively arranged with some semi-circular recesses 10, in the cavity forming at described two corresponding semi-circular recesses 10, be wound with radio-frequency induction coil 11, described radio-frequency induction coil 11 is connected with high-frequency and high-voltage power supply by high frequency switch board 2.
As shown in Figure 1 and Figure 2, in this example, in order to prevent that coil from coming off, in the outside of described polymer thermal insulative cotton, be evenly provided with eight radio-frequency induction coil fixed heads.
Above-mentioned high-frequency induction formula holding furnace, by being wound around radio-frequency induction coil in the cavity forming at two corresponding semi-circular recesses, can effectively prevent that radio-frequency induction coil from coming off or overlapping, and temperature homogeneity is good, long service life.
