Above-mentioned continuous tunnel furnace duct insert heater is characterized in that: the quantity of described heater strip glass winding post is nine.
Above-mentioned continuous tunnel furnace duct insert heater is characterized in that: offer the threaded mounting hole that is threaded with side shield and short shutter for the heater mounting panel on the described heater mounting panel.
Above-mentioned continuous tunnel furnace duct insert heater is characterized in that: described binding post is ceramic wiring terminal.
The utility model compared with prior art has the following advantages:
1, of the present utility model simple in structure, rationally novel in design, be easy to install.
2, the utility model is heater design rectangularity zone square formation, will every heater strip twines glass tube by mica dividing plate two and separates, and makes the heating region of heater can the larger zone of radiation, makes air-flow can pass through the abundant heating of heater strip; And then by heater strip 4 is designed to the three-dimensional spiral column, heater strip all is exposed in the air as far as possible, therefore heater strip 4 is wrapped in elongated heater strip and twines on the glass tube, increased the heat-conducting area of heater strip, through the heater that designs like this, heating effect is good, and the efficiency of heating surface is high.
3, realization cost of the present utility model is low, and result of use is good, is convenient to promote the use of.
In sum, the utility model is simple in structure, and is rationally novel in design, and functional reliability is high, and long service life is convenient to safeguard and the efficiency of heating surface is high, good, the energy-conserving and environment-protective of heating effect, and result of use is good, is convenient to promote the use of.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
A kind of continuous tunnel furnace duct insert heater as shown in Figure 1, comprise base plate 11 and three side shields 9 that are installed on the base plate 11 and link together, and the heater mounting panel 6 that is arranged on three described side shield 9 upper ends, three described side shield 9 inside are provided with mica sheet division board 1, mica sheet division board 23 and mica sheet division board 3 13, described mica sheet division board 1 is positioned at the top of mica sheet division board 23, described mica sheet division board 3 13 is near base plate 11, three described side shield 9 interior vertically being provided with for mica sheet division board 1 is installed, the mica sheet ceramic support post 10 of mica sheet division board 23 and mica sheet division board 3 13, distance between described mica sheet division board 1 and the mica sheet division board 23 equals the distance between mica sheet division board 23 and the mica sheet division board 3 13, three described side shield 9 inside vertically are provided with a plurality of heater strip glass winding post 5, the upper end of described heater strip glass winding post 5 is passed mica sheet division board 23 and is connected with mica sheet division board 1, the lower end of described heater strip glass winding post 5 is installed on the mica sheet division board 3 13, all be wound with heating wire 4 on a plurality of described heater strip glass winding post 5, be provided with three binding posts 1 on the described heater mounting panel 6, described heating wire 4 is connected by electric wire 7 with binding post 1, the top of described mica sheet division board 1 is provided with heat-insulation and heat-preservation packed layer 8, and the top of two side shields 9 that the position is corresponding is equipped with for the short shutter 14 with 8 sealings of heat-insulation and heat-preservation packed layer.The quantity of described heater strip glass winding post 5 is nine.Offer the threaded mounting hole 2 that is threaded with side shield 9 and short shutter 14 for heater mounting panel 6 on the described heater mounting panel 6.Described binding post 1 is ceramic wiring terminal.
In the present embodiment, heat-insulation and heat-preservation packed layer 8 is used for filling heat insulation preservation material, because insert like this in the middle of the air channel because the heater volume is huge, outside words of directly installing, without heat-insulation and heat-preservation, can reduce the integral heat insulation effect of continuous tunnel furnace, therefore increase the packed layer filling heat insulation preservation material.Because heater inserts in the middle of the air channel, by the time the wind speed in the middle of is because blast is large, therefore wind speed is very fast, if heating region is little, air-flow is difficult to the heating effect that reaches desirable, and hot blast is difficult to guarantee heating effect, therefore with heater design rectangularity zone square formation, by mica dividing plate 23 every heater strip is twined glass tube 5 and separate, make the heating region of heater can the larger zone of radiation, make the air-flow can be through the abundant heating of heater strip 4; And then by heater strip 4 is designed to the three-dimensional spiral column, make heater strip 4 all be exposed in the air as far as possible, therefore heater strip 4 being wrapped in elongated heater strip twines on the glass tube 5, increased the heat-conducting area of heater strip 4, through the heater that designs like this, heating effect is good, and the efficiency of heating surface is high.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection range of technical solutions of the utility model.
