Fig. 3 is the guide groove sealed structural representation.
Among the figure: 1, door-plate, 2, peep hole, 3, kiln wall steel skeleton, 4, guide groove, 5, the total air channel of tunnel cave, 6, hoisting frame, 7, adjust bolt, 8, chain, 9, the kiln top, 10, motor, 11, decelerator, 12, watt frame, 13, sprocket wheel, 14, lift shaft, 15, counterweight, 16, balancer shaft, 17, handwheel, 18, sealing strip, 19, at the bottom of the kiln, 20, sand sealing groove, 21, sleeper, 22, the sand seal plate, 23, door windward road junction, 24, door frame, 25, the interlayer seal bar, 26, the seal bar axle, 27, the kiln top sealing rod, 28, connecting rod, 29, pin, 30, control stick, 31, fixed axis, 32, tunnel cave interlayer crack between a door and its frame, 33, the tunnel cave interlayer, 34, the tunnel cave firing chamber, 35, the seal bar axle, 36, the guide groove seal bar, 37, connecting rod, 38, pin, 39, the connecting rod cover, 40, pin, 41, the pull bar cover, 42, pull bar.
The specific embodiment
Guide groove seal bar 36 adopts pipe to make seal bar axle 35, and coated outside has fire-retardent fiber felt- rug.Connecting rod 37 and 35 welding of seal bar axle, connecting rod cover 39 is enclosed within on the pin 38, and pin 38 is fixed on the guide groove 4.Pull bar 42 is enclosed within on another pin 40 by the pull bar cover 41 of its front end, and this pin 40 is fixedlyed connected with seal bar axle 35, and stretch out outside the guide groove 4 pull bar 42 rear ends.Kiln top sealing rod 27, interlayer seal bar 25 are close with guide groove seal bar 36 structures, interlayer seal bar 25 is rotatably connected with control stick 30 and fixed axis 31, fixed axis 31 stretches out outside the kiln wall, and control stick 30 is positioned at kiln wall outside, and fixed axis 31 is contained in interlayer 33, Yao Bishang by axle sleeve.
When piling up adobe in the mobile tunnel furnace, stay one to come to nothing and draw seam at a certain distance, be used for putting cut-off gate and kiln hood door, two come to nothing that to draw between the seam be a hack, and the fire hack that whenever advances just needs to move a tunnel cave.The operating sequence of mobile tunnel cave is: Blowing stopper, open the kiln hood door, mention cut-off gate, move forward tunnel cave after, whether the position of guarding the gate by peep hole 2 just in time puts in place, and then closes the kiln hood door, puts down cut-off gate, starts blower fan and proceeds the roasting operation.
When putting cut-off gate, put down door earlier, be pulled outwardly pull bar 42, allow guide groove seal bar 36 that the gap between door and the guide groove 4 is sealed.Move control stick 30, interlayer seal bar 25 is fallen, seal interlayer crack between a door and its frame 32.Directly move kiln top sealing rod 27 with hand, make it fall the crack between a door and its frame of sealing kiln top 9.When carrying cut-off gate, must open kiln top sealing rod 27, interlayer seal bar 25 and guide groove seal bar 36 respectively earlier, restart motor 10 (or moving handwheel 17) and be pulled upwardly door.At this moment just can mobile tunnel cave, whenever move once, door is all wanted lifting once, and sealing device all will be worked once, and the environment temperature height changes big, so very high to the requirement of sealing property at the bottom of the kiln.
