Detailed description of the invention
As depicted in figs. 1 and 2, the present invention includes ceramic wiring terminal 1, heater is installed screwed hole 2, mica sheet division board 3, heater strip 4, heater strip glass winding post 5, heater installing plate 6, heat-insulation and heat-preservation packed layer 8, side shield 9, mica sheet side gripper shoe 10, base plate 11 and header board 12, the quantity of described mica sheet division board 3 and mica sheet side gripper shoe 10 is multiple, described mica sheet division board 3, mica sheet side gripper shoe 10 and base plate 11 form square formation heater strip framework are installed, described heater strip glass winding post 5 is laterally arranged on the inside of described square formation heater strip installation framework, described heater strip 4 is three-dimensional spiral shape uniform winding in heater strip glass winding post 5, described side shield 9 is arranged on described square formation heater strip the sidepiece of framework is installed, the lower end of described side shield 9 and base plate 11 weld, described heat-insulation and heat-preservation packed layer 8 is positioned at described square formation heater strip and the top of framework is installed and welds with side shield 9, the upper end of described side shield 9 is fixedly connected with heater installing plate 6 by screw, described ceramic wiring terminal 1 and heater are installed screwed hole 2 and are all arranged on heater installing plate 6, the top of described side shield 9, heat-insulation and heat-preservation packed layer 8 and heater installing plate 6 form electric wire and place cavity, the front portion that described header board 12 is arranged on described electric wire places cavity, the electric wire 7 of described heater strip 4 is placed cavity and joins with ceramic wiring terminal 1 through heat-insulation and heat-preservation packed layer 8 and described electric wire successively from the bottom to top.
As depicted in figs. 1 and 2, the quantity that described heater is installed screwed hole 2 is three, and three described heaters are installed screwed hole 2 and are a line laying.
As depicted in figs. 1 and 2, the quantity of described ceramic wiring terminal 1 is four, and four described ceramic wiring terminal 1 symmetries are laid on four angles of heater installing plate 6.
In the present embodiment, mica sheet side gripper shoe 10 is mounted in the draw-in groove of base plate 11 and mica sheet division board 3.
In the present invention, in order to make the heater of continuous tunnel furnace easy for installation, we adopt the outside Method for Installation of heater, from outside, heater is inserted in the middle of the heating air duct of continuous tunnel furnace, then heat-insulation and heat-preservation packed layer 8 is set on heater, heat-insulation and heat-preservation packed layer 8 plays heat-insulation and heat-preservation, because it is central because heater volume is huge to insert like this air channel, outside directly installation, without heat-insulation and heat-preservation, can reduce the integral heat insulation effect of continuous tunnel furnace.Because heater inserts in the middle of 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 ensure heating effect, therefore by heater design rectangularity region square formation, heater strip glass winding post 5 is laterally installed, and prevents from occurring longitudinally to come off to cause short circuit or initiation fire when heater strip 4 from heating; By mica sheet side gripper shoe 10, every heater strip glass winding post 5 is separated, make the heating region of heater can the larger region 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 three-dimensional spiral column, heater strip 4 is all exposed in air as far as possible, therefore heater strip 4 is wrapped in elongated heater strip glass winding post 5, increase the heat-conducting area of heater strip 4, through the heater designing like this, heating effect is good, and the efficiency of heating surface is high.
Due to the heating of working for a long time of continuous tunnel furnace heater, therefore being easy to cause the efficiency of heating surface to reduce even damages, therefore will often change heater, because continuous tunnel furnace is an airtight equipment, upper top cover is heavier, if change heater by inconvenience very by opening upper top cover, therefore adopt structure of the present invention, replacing removes and installs heater by the convenience becoming very, on heater installing plate 6, have four heater mounting hole, dig having heaters at hole periphery screwed hole is installed, heater can be inserted in the middle of ventilation shaft along this hole, the heater installing plate being integrally connected with heater can be supported on the top cover of continuous tunnel furnace, use screw fixed heater installing plate to the upper top cover of continuous tunnel furnace, in the middle of the ventilation shaft that is arranged on continuous tunnel furnace that heater can be very stable like this, in order to prevent causing short circuit along quartz ampoule longitudinal dilatation landing in the thermoplastic process of heater strip of heater, therefore heater strip glass winding post 5 can be laterally installed and can avoid problems.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
