Description
Technical field
Heating equipment field is the utility model is related to, especially a kind of boundling short-circuit type electricity for being used to heat non conducting fluid
Heater.
Background technology
Existing industrial boundling short-circuit type electric heater is one frequently with the structure of circulating type cluster short-circuit type electric heater
Kind is achieved the goal using the form of heater element electrothermal tube by electrothermal tube internal heating wire and magnesia powder through hyperbaric heating.
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 frequently with increase container diameter or reduces heater loads to realize, also leads
Cause cost too high.
The content of the invention
The technical problems to be solved in the utility model is：A kind of resistant to elevated temperatures boundling short-circuit type electric heater is provided.
To solve the above problems, the utility model provides a kind of boundling short-circuit type electric heater, including it is provided with disengaging
The housing of stomata, several support frames are fixed with housing, there are several heating tubes along housing is axially arranged on support frame, add
Heat pipe 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.
Advantageous effects of the present utility model are：
1, because boundling short-circuit type electric heater is conductive blank pipe, caused at high temperature in the absence of traditional electrothermal tube electrical heating wire
Magnesium oxide insulated is set to decline the phenomenon caused with body leakage tripping operation.
2, the problem of breakdown due to non-oxidation magnesium by high temperature, therefore service life is grown.
3, simple in construction, no 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 the utility model boundling short-circuit type electric heater；
Fig. 2 is the schematic cross-section at A-A in the utility model boundling short-circuit type electric heater Fig. 1；
Specific embodiment：
Embodiment cited by the utility model, it is only intended to help and understands the utility model, should not be construed as to this reality
With the restriction of novel protected scope, for those skilled in the art, the utility model thought is not being departed from
On the premise of, the utility model can also be made improvements and modifications, these are improved and modification also falls into the utility model right
In claimed scope.
As shown in figure 1, the utility model includes being provided with air inlet and the cylindrical shell 1 of gas outlet, set in housing 1
There are three support frames 8, support frame 8 is bolted to enclosure interior.There are nine heating along housing is axially arranged on support frame 8
Pipe 2, heating tube 2 are conductive blank pipe, are made of metal material, such as：Stainless steel or high nickel alloy material etc..Add as shown in Figure 1
The first connector 6 and the second connector 4 of phase same material with itself, every three heating tube strings is respectively adopted in the both ends of heat pipe 2
Join for one group, totally three groups, parallel relationship is formed between every three groups.The inside mounting temperature sensor 11 of housing 1, added for monitoring
The temperature of thermal medium.
As shown in Fig. 2 it is 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 summary, the utility model provides a kind of boundling short-circuit type electric heater, and its heating tube is conductive blank pipe, is led
Electric blank pipe is both conductive resistive element and radiator body, avoids the electric leakage occurred in original technology by magnesia high temperature and shows
As only need to even connect with the mains can when in use, and simple in construction, service life is longer, greatly reduces manufacturing cost.
