The specific embodiment
as depicted in figs. 1 and 2, the utility model comprises 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 a plurality of, described mica sheet division board 3, mica sheet side gripper shoe 10 and base plate 11 form the square formation heater strip framework are installed, described heater strip glass winding post 5 laterally is arranged on the inside that described square formation heater strip is installed framework, described heater strip 4 is three-dimensional spiral shape uniform winding on heater strip glass winding post 5, described side shield 9 is arranged on the sidepiece that described square formation heater strip is installed framework, the lower end of described side shield 9 and base plate 11 welding, 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 all are 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, described header board 12 is arranged on the front portion that described electric wire is placed cavity, the electric wire 7 of described heater strip 4 passes successively from the bottom to top heat-insulation and heat-preservation packed layer 8 and described electric wire is placed cavity and joins with ceramic wiring terminal 1.
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 utility model, for the heater that makes continuous tunnel furnace easy for installation, we adopt the outside Method for Installation of heater, from the 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 the 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 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, heater strip glass winding post 5 is laterally installed, and occurs vertically to come off to cause short circuit or initiation fire when preventing heater strip 4 heating; By mica sheet side gripper shoe 10, every heater strip glass winding post 5 is separated, make the heating region of heater can radiation larger zone, 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 air as far as possible, therefore heater strip 4 is wrapped on elongated heater strip glass winding post 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.
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 general inconvenience very by opening upper top cover, therefore adopt the utility model structure, replacing removes and installs will become very convenience of heater, have four heater mounting hole on heater installing plate 6, dig having heaters at the hole periphery screwed hole is installed, in the middle of heater can being inserted ventilation shaft along this hole, the heater installing plate that is 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 cause short circuit along quartz ampoule longitudinal dilatation landing in the thermoplastic process of the heater strip that prevents heater, therefore heater strip glass winding post 5 can laterally be installed can avoid problems.
The above; it is only 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 domain of technical solutions of the utility model.
