Therefore, the utility model be for three kinds of heating tubes in the market it is newly developed go out it is a kind of it is simple in structure, using peace Entirely, at low cost, fever uniformly, the high high temperature soak type heater of high temperature resistant, the thermal efficiency.

Utility model content

Simple in structure, safe to use, at low cost, uniform, high temperature resistant of generating heat that the purpose of this utility model is to provide one kind, The high high temperature soak type heater of the thermal efficiency.

The technical solution of the utility model is as follows：A kind of high temperature soak type heater, including heating tube body and two lead Electric wire, the heating tube body include shell, insulating powder last layer inside the shell are arranged and is arranged in the insulating powder last layer Heating layer between shell, the heating layer include that two electric heating draw stick and are screwed in the electric heating and draw spiral heating on stick Silk, the spiral heating silk are point distributed architectures of five sections of different gaps to make, and the gap between heater strip is from center Position is tapered into both ends, the electric heating draw stick extend from one end tapping of the shell and respectively with the conductor wire The trepanning end of connection, the shell is provided with high temperature porcelain head, and the conductor wire draws with electric heating is provided with resistance to height on the linkage section of stick Warm porcelain bead.

In the above-mentioned technical solutions, the spiral heating silk is using Germany's BGH nichrome heat silks.

In the above-mentioned technical solutions, it is that nickel-base alloy draws stick that the electric heating, which draws stick,.

In the above-mentioned technical solutions, the conductor wire uses high temperature pure nickel line.

In the above-mentioned technical solutions, the shell is stainless steel casing.

Compared with the existing technology, the beneficial effects of the utility model are：A kind of high temperature soak provided by the utility model Type heater, including heating tube body and two conductor wires, the heating tube body include shell, the insulation of setting inside the shell Powder bed and the heating layer being arranged between insulating powder last layer and shell, the heating layer draw stick including two electric heating and are screwed on Draw the spiral heating silk on stick in electric heating, spiral heating silk is point distributed architecture of five sections of different gaps to make, heating Silk between gap tapered into from middle position to both ends, electric heating draw stick extend from one end tapping of shell and respectively with Conductor wire connects, and the trepanning end of shell is provided with high temperature porcelain head, and conductor wire draws with electric heating is provided with high temperature resistant on the linkage section of stick Porcelain bead.The utility model has the characteristics that simple in structure, safe to use, at low cost, generate heat uniform, high temperature resistant, the thermal efficiency are high.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Specific implementation mode

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Referring to Fig. 1, a kind of high temperature soak type heater of the utility model, including heating tube body and two conductor wires 2, heating tube body includes shell 11, the insulating powder last layer 12 that is arranged in shell 11 and setting insulating powder last layer 12 with it is outer Heating layer between shell 11, the heating layer include that two electric heating draw stick 31 and are screwed in electric heating and draw spiral heating silk on stick 31 32, the electric heating draws stick 31 and draws stick using nickel-base alloy, and the spiral heating silk 32 is using Germany's BGH nichrome heat silks, the spiral shell It is point distributed architecture of five sections of different gaps to make to revolve heater strip 32, and the gap between heater strip is from middle position to two End tapers into, thus for physical principle the both ends rapid heat dissipation heater strip of heater be distributed to want it is closeer, and it is more past in Between radiate slower, the distribution of heater strip wants more sparse, and the electric heating draws stick 31 and extends and divide from one end tapping of shell 11 It is not connect with conductor wire 2, the trepanning end of shell 11 is provided with high temperature porcelain head 4, and conductor wire 2 draws with electric heating to be set on the linkage section of stick 31 It is equipped with high temperature resistant porcelain bead 5.

The conductor wire 2 selects high temperature pure nickel line, in conjunction with strands technique, be effectively ensured the heatproof of material, hardness, The welding of the end of a thread ensures twisted wire not raw edge, is easy to use and installs.

The shell 11 is stainless steel casing.Its material is incoloy840, and incoloy840 has the chromium of higher percent And nickel, there is under hot environment good resistance to oxidation, corrosion resistance to have higher elevated temperature strength, at high temperature can continuous operation, Welding performance is good.

The utility model internal mechanism reasonable design draws stick and insulating powder using import nickel-base alloy, and thermal coefficient is high, Nozzle is sealed using high temperature porcelain head, and conducting wire selects heat safe 95 magnetic as insulating materials, and the high temperature resistant porcelain bead on conducting wire has The features such as high temperature resistant, electric property is stable, pollution-free.

In conclusion the structure design of the utility model, make its be provided simultaneously with it is simple in structure, safe to use, at low cost, Fever uniformly, the high feature of high temperature resistant, the thermal efficiency.Suitable for being used more widely.
