The specific embodiment
As the automatic stove face plate of Fig. 1, Fig. 2 and a kind of diffusion furnace shown in Figure 3, the diffusing stove full name of using this technology is " a tubular type high temperature dispersing furnace ", and its burner hearth is a round tube shape structure, and the stove internal cavity is boiler tube, opening part is a fire door.The utility model comprises the stove face plate 1 that is installed in the fire door cabinet 12, universal bearing 2, stove face plate plane deflection driven mechanism, the axially-movable driving mechanism of stove face plate and control software thereof.Stove face plate 1 is exactly a cover plate that is complementary with fire door, and this piece cover plate is contained in one and is with on the flexible universal bearing 2, and this universal bearing 2 is in the home position of stove face plate 1, its elastic characteristic can so that fire door can be not crooked and reliably cover fire door.The rotating shaft 6 that stove face plate plane deflection driven mechanism includes the bent plate 3 that links to each other with universal bearing 2, hinged securement bent plate lower end and shaft seat, the connecting axle 4 that links to each other with bent plate 3 middle parts and be hinged on connecting axle 4 on connecting rod 5, the moving cylinder 9 that drives of deflection transhipment that links to each other with connecting rod 5, the deflection transhipment is moving, and to drive cylinder 9 are straight line mobile model cylinders.The base plate 10 (the moving cylinder 9 that drives of shaft seat end and deflection transhipment all is fixed on the base plate 10) of sleeve mechanism is installed.When the moving driving of deflection transhipment cylinder 9 stretches, connecting rod 5 will spur bent plate 3 middle parts.The bottom of bent plate 3 is fixedly mounted on the shaft seat on the base plate, so the result of driving makes bent plate 3 rotate around the rotating shaft 6 of bent plate lower end.Thereby move along the camber line that with rotating shaft 6 is the center of circle with universal bearing 2 and cover plate the upper end that drives bent plate 3.When deflection transhipment is moving when driving cylinder 9 withdrawals, stove face plate 1 moves to the position that gets out of the way by position, the axle center of boiler tube (boiler tube and burner hearth 13 axis coinciding); When the moving driving of deflection transhipment cylinder 9 stretched out, stove face plate 1 was moved to the shaft core position of boiler tube by the position that gets out of the way.The axially-movable driving mechanism of stove face plate 1 mainly is made up of circular line slideway auxiliary 8, the linear drives cylinder 11 of mounting seat, pair of parallel.The circular line slideway auxiliary 8 and the boiler tube axis parallel of that pair of parallel; The telescopic displacement track of linear drives cylinder 11 also with the boiler tube axis parallel.The telescopic shaft of cylinder is mounted on the base plate 10 of stove face plate plane deflection driven mechanism, when linear drives cylinder 11 stretches, will do the axial rectilinear motion of boiler tube with the base plate 10 that stove face plate plane deflection driven mechanism is installed.Stove face plate 1 is starched the open position that allows that is in the next door in the process of sending quartz boat at SiC, put quartz boat at the SiC slurry and withdrawed from rear screw shaft, the moving cylinder 9 that drives of deflection transhipment stretches out, connecting rod 5 promotes bent plate 3 middle parts, thereby the upper end of drive bent plate 3 moves to the shaft core position of boiler tube along the camber line that with the rotating shaft is the center of circle together with universal bearing 2 and stove face plate 1.Linear drives cylinder 11 does to regain displacements then, does and boiler tube axle center moving horizontally in the same way with stove face plate plane deflection driven mechanism and stove face plate 1, thereby covers fire door.After diffusion technique finished, linear drives cylinder 11 did to stretch out displacement, did and boiler tube axle center moving horizontally in the same way with stove face plate plane deflection driven mechanism and stove face plate 1, thereby opened fire door.Deflection is transported the moving cylinder 9 that drives and is regained, connecting rod 5 pulling bent plates 3 middle parts, thus the upper end of drive bent plate 3 moves to the open position that allows on next door along the camber line that with rotating shaft 6 is the center of circle together with universal bearing 2 and stove face plate 1.The SiC slurry can enter boiler tube and get quartz boat.
Whole process is controlled automatically, and has defencive functions such as the position is chain, interlocking.With reference to Fig. 2, Fig. 3,1. when stove face plate was in closed condition, the rotating part of stove face plate had the trend that clockwise rotates under the effect of gravity, and as no external force effect, stove face plate can not rotate counterclockwise with rotating shaft 6.2. when stove face plate is in open mode, structural design guarantees that the center of gravity of the rotating part of stove face plate crossed peak, and under the effect of gravity, the rotating part of stove face plate has the trend that rotates counterclockwise, as not having the external force effect, stove face plate can not clockwise rotate with rotating shaft 6.3. the control of stove face plate is realized by PLC control pneumatic control valve, the design of electric control loop and the selection of pneumatic control valve are guaranteed when having a power failure, the rod chamber of all cylinders and the compressed air of rodless cavity are closed simultaneously, and promptly cylinder stops any action at once when having a power failure.More than 3 guarantee this patent equipment when running into fortuitous events such as unexpected power failure, stove face plate does not have any action.Even stove face plate in the running that opens or closes, runs into when having a power failure just, stove face plate also can stop action at once, rests on the position when having a power failure, and can not break other thing (silicon chip, quartz boat, SiC slurry etc.).
