Described upper steel cylinder top offers vent, is fixed with hopper, hopper lower openings and feeding inlet on described body of heater.
The utility model compared with prior art has the following advantages:
1, owing to being provided with the some siphunculus that communicate with annular passage and burner hearth in fire resisting material of furnace body layer, steel cylinder bottom, stage casing is provided with vent-pipe, and vent-pipe one end communicates with annular passage, the other end and blower fan join, when charing is ignited, can dry by blower fan, improve the moulded coal speed of igniting; In carbonization process, when carbonization temperature is too low, when slowing down discharging speed, also can blow by blower fan, promote carbonization temperature, not only can make quality product better be guaranteed, and working efficiency is improved greatly.
2, because body of heater stage casing steel cylinder is radially fixed with some spy fire tubes, in the refractory masses of the extension line of visiting fire tube longitudinal center line along each between annular passage and burner hearth, be provided with each and visit fire tube some siphunculus of same diameter one to one, when there is bonding phenomenon in moulded coal in stove in carbonization process, drill rod can be inserted from visiting fire tube and siphunculus, process in time.
3, lower furnace portion is funnel-shaped structure, is conducive to material descending.
4, body of heater shell is steel integrated structure, in the time of need to moving, can use lifting appliance to move, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model charring furnace.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model vertical coal charring furnace, comprise body of heater 1, opening for feed 2, discharge gate 3, chimney 4, body of heater shell is mainly comprised of three sections of isometric steel cylinders, the diameter of stage casing steel cylinder 5 is greater than, hypomere steel cylinder 6, 7 diameter, on, hypomere steel cylinder 6, 7 are welded and fixed by doughnut-shaped steel plate 8 with stage casing steel cylinder 5, on, hypomere steel cylinder 6, 7 are welded with respectively steel top board 9 and base plate 10, chimney 4 is welded on top board 9, hopper 11 and opening for feed 2 are located at epimere steel cylinder 6 tops, hopper 11 lower openings communicate with opening for feed 2, discharge gate 3 is opened in base plate 10 middle parts, observe for convenience charing situation in stove, epimere steel cylinder 6 tops also offer vent 12, the burner hearth 14 surrounding for refractory masses 13 in body of heater 1, between the barrel of refractory masses 13 and stage casing steel cylinder 5, leave annular passage 15, stage casing steel cylinder 5 is radially fixed with the spy fire tube 18 of three parallel rows, eight spy fire tubes of every row setting are distributed on stage casing steel cylinder 5, each is visited fire tube one end and communicates with annular passage 15, the other end stretches out outside body of heater 1, the extension line of visiting fire tube longitudinal center line is provided with and each spy fire tube some siphunculus 20 of same diameter one to one along each in the refractory masses of 14, annular passage 15 and burner hearth, steel cylinder 5 bottoms in stage casing are provided with vent-pipe 16, vent-pipe 16 one end communicate with annular passage 15, the other end and blower fan 17 join, burner hearth 14 middle and upper parts are tubular, bottom Stepwize Shrink is funnel-form, funnel bottom opening communicates with discharge gate 3, under discharge gate 3, be provided with the vibratory screening apparatus that coordinates blanking, under body of heater 1 shell, edge is welded with three converter body support steel poles 19 that are mutually 120 degree angles.
