Description
Technical field
The present invention relates to heating equipment field, especially a kind of boundling short-circuit type electrical heating for heating non conducting fluid
Device.
Background technology
Existing industrial boundling short-circuit type electric heater, frequently with the structure of circulating type cluster short-circuit type electric heater, is one
Plant in the form of heater element electrothermal tube, achieved the goal through hyperbaric heating by electrothermal tube internal heating wire and magnesia powder.
The major defect of the structure is：
1st, influenceed by magnesia high-temperature insulation, the maximum temperature of traditional structure heating medium is usually no more than 600 DEG C.
2nd, traditional boundling short-circuit type electric heater realized frequently with increasing container diameter or reduce heater loads, is also led
Cause high cost.
The content of the invention
The technical problem to be solved in the present invention is：A kind of resistant to elevated temperatures boundling short-circuit type electric heater is provided.
To solve the above problems, the invention provides a kind of boundling short-circuit type electric heater, including air inlet/outlet is provided with
Housing, several support frames are fixed with housing, have several heating tubes, heating tube along housing is axially arranged on support frame
It is conductive blank pipe.
Further, insulator is provided between support frame and heating tube.
Further, enclosure interior has sensor.
Further, insulator is made of ceramic materials.
The method have the benefit that：
1, because boundling short-circuit type electric heater is conductive blank pipe, oxygen is caused at high temperature in the absence of traditional electrothermal tube electrical heating wire
Change magnesium insulation and decline the phenomenon for causing to trip with body leakage.
2, due to the problem that non-oxidation magnesium is punctured by high temperature, therefore long service life.
3, simple structure, without heating wire and electrothermal tube manufacturing cost, therefore manufacturing cost is relatively low.
Brief description of the drawings：
Fig. 1 is the longitudinal profile structure schematic of boundling short-circuit type electric heater of the present invention；
Fig. 2 is the schematic cross-section at A-A in boundling short-circuit type electric heater Fig. 1 of the present invention；
Specific embodiment：
Embodiment cited by the present invention, is only intended to help and understands the present invention, should not be construed as to the scope of the present invention
Limit, for those skilled in the art, without departing from the inventive concept of the premise, can also be to this hair
Bright to make improvements and modifications, these are improved and modification is also fallen into the range of the claims in the present invention protection.
As shown in figure 1, the present invention includes being provided with the cylindrical shell 1 of air inlet and gas outlet, three are provided with housing 1
Individual support frame 8, support frame 8 is bolted to enclosure interior.There are nine heating tubes 2 along housing is axially arranged on support frame 8,
Heating tube 2 is conductive blank pipe, is made of metal material, such as：Stainless steel or high nickel alloy material etc..Heating tube 2 as shown in Figure 1
Two ends first connector 6 and the second connector 4 of phase same material with itself is respectively adopted, every three heating tubes series connection is one
Group, parallel relationship is formed between every three groups by totally three groups.The inside mounting temperature sensor 11 of housing 1, for monitoring heated medium
Temperature.
As shown in Fig. 2 being the schematic cross-section at A-A in boundling short-circuit type electric heater Fig. 1, support frame 8 and heating tube 2
Between be provided with insulator 9, prevent leaky.Insulator 9 is typically made of ceramic materials.
In sum, the invention provides a kind of boundling short-circuit type electric heater, its heating tube is conductive blank pipe, conductive empty
Pipe is both conductive resistive element and radiator body, it is to avoid the leaky occurred by magnesia high temperature in original technology,
Only need to even be connected with the mains when using just can be so that simple structure, service life is more long, greatly reduces manufacturing cost.
