Abstract
The utility model discloses a spiral vertical winding type electric heating device, which comprises a core bar, a spiral tube, a leading-out bar, a casing pipe, a first connecting plug, a plurality of second connecting plugs, a tray and a spiral resistance band. The spiral vertical winding type electric heating device utilizes the continuous spiral resistance band to substitute a thermo resistor connected in welding manner in the prior art to be a heating component, accordingly greatly reduces material use under the condition of same heat emission, and causes no problem of the thermo resistor coming off due the fact that the device has no welding spots, thereby being capable of reducing maintenance and increasing production efficiency. Additionally, since the surface area of the heating component is increased, the device can reduce high surface thermal load and prolongs service life thereby.
Description
Technical field
The utility model relates to a kind of electric heater, particularly relates to a kind of used for industrial furnace spiral vertical winding type electric heating device.
Technical background
The interior electric heater unit of common used in industry stove is normally connected by a plurality of metal fever resistance as heating element and is constituted at present, is to utilize welding method to link together between the adjacent heat resistance.Because welding material and technology, these electric heater units in use problems such as distortion and thermal resistance come off occur through regular meeting, will influence the normal operation of industrial furnace like this and increase maintenance capacity.In addition, also there is the surface thermal load height of heating element in this electric heater unit, so the life-span is short, and shortcoming such as the consumption of material is big.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of consumption that can reduce material, and the spiral vertical winding type electric heating device that can increase the service life.
In order to achieve the above object, the spiral vertical winding type electric heating device that provides of the utility model comprises plug, helix tube, eduction rod, sleeve pipe, first connection plug, a plurality of second connection plug, pallet and spiral resistive band; Wherein an end of plug is connected an end of power supply by steel plate; Helix tube is installed in the other end outside of plug, and is formed with helical groove on the outer circumference surface; Eduction rod and the plug spacing of being separated by be arranged in parallel, and the one end is fixed on and is positioned at inboard end face exterior periphery place on the helix tube, and the other end is connected the other end of power supply by another block plate; Sleeve pipe is fixed on the middle part outer circumference surface of plug in the mode adjacent with helix tube; First connection plug, a plurality of second connection plug and pallet are installed in an end outside of plug and eduction rod successively, and first connection plug and sleeve pipe are adjacent; The spiral resistive band then twines in the groove that is arranged on the helix tube, and the one end links to each other with the other end of plug, the other end then with eduction rod on the end that links to each other with helix tube join.
Be separately installed with a fastening backing plate and a packing ring on the described plug that is positioned at helix tube and pallet outer end.
On the described eduction rod that is positioned at the pallet outer end packing ring is installed.
One end of described plug is formed with a hanger.
The spiral vertical winding type electric heating device that the utility model provides is to utilize continuous spiral resistance to bring to replace thermal resistance that the welding manner of prior art connects and as heating element, has the consumption that can reduce material under the prerequisite of identical caloric value significantly like this, and by there not being pad thereon, so the thermal resistance problem that comes off can not occur, therefore can reduce maintenance capacity and enhance productivity.In addition, owing to increased the surface area of heating element, thus can reduce its surface thermal load height, thus its useful life can be prolonged.
Description of drawings
The spiral vertical winding type electric heating device structural representation that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the spiral vertical winding type electric heating device that the utility model provides is elaborated.
As shown in Figure 1, the spiral vertical winding type electric heating device that provides of the utility model comprises plug 9, helix tube 3, eduction rod 7, sleeve pipe 4, first connection plug 5, a plurality of second connection plug 6, pallet 14 and spiral resistive band 2; Wherein an end of plug 9 is connected an end of power supply by steel plate 12; Helix tube 3 is installed in the other end outside of plug 9, and is formed with helical groove on the outer circumference surface; Eduction rod 7 and plug 9 spacing of being separated by be arranged in parallel, and the one end is fixed on and is positioned at inboard end face exterior periphery place on the helix tube 3, and the other end is connected the other end of power supply by another block plate 12; Sleeve pipe 4 is fixed on the middle part outer circumference surface of plug 9 in the mode adjacent with helix tube 3; First connection plug 5, a plurality of second connection plug 6 and pallet 14 are installed in an end outside of plug 9 and eduction rod 7 successively, and first connection plug 5 and sleeve pipe 4 are adjacent; Spiral resistive band 2 then winding is arranged in the groove on the helix tube 3, and the one end links to each other with the other end of plug 9, the other end then with eduction rod 7 on the end that links to each other with helix tube 3 join.
Be separately installed with a fastening backing plate 1 and a packing ring 13 on the described plug 9 that is positioned at helix tube 3 and pallet 14 outer ends.
On the described eduction rod 7 that is positioned at pallet 14 outer ends a packing ring 8 is installed.
One end of described plug 9 is formed with a hanger 10.
Described helix tube 3, first connection plug 5, second connection plug 6 and pallet 14 adopt heat-resistant insulation material to make.
When spiral vertical winding type electric heating device that needs utilize the utility model to provide heats when improving the temperature in the industrial furnace, energized at first, at this moment power supply will give the spiral resistive band 2 heating by plug 9 and eduction rod 7, thereby the temperature of spiral resistive band 2 is raise, and consequent heat is dispersed in the surrounding space through the surface of spiral resistive band 2.
