Detailed description of the invention
Slag-draining device of the present invention forms primarily of broken conveying blade, spiral pushing off the slag delivery board and dynamical system.Broken conveying blade is mainly used in fragmentation and the propelling movement of lime-ash, and spiral pushing off the slag delivery board mainly makes slag discharge fast and effectively.The velocity of discharge of lime-ash is fast, discharges respond well.
The present invention adopts following scheme:
Broken conveying blade is all connected in ash-pan projection, and front end is broken conveying blade main body, and far-end is connected with another broken conveying blade, lowers gradually from front end to rear end projection, and rear end and the protruding junction of ash-pan seamlessly transit.Broken conveying blade is all welded in ash-pan projection.Ash-pan projection is fixed in the middle of ash-pan.
The body top of broken conveying blade increases gradually to lower lobes.The lower body part height of projection of broken conveying blade can be set to 5cm to 10cm according to pyrolysis gasification furnace output lime-ash.
Blade spiral on broken conveying blade is uniform to be welded in ash-pan projection.
In adjacent two blades, last blade rear end and the protruding smooth connection of ash-pan, a rear blade front end is adjacent connection.
Refuse pyrolysis gasification furnace spiral pushing off the slag delivery board is welded on refuse pyrolysis gasification furnace furnace wall, from low side lime-ash entrance at an angle (5 ° to 15 °) uniform spiral rise to high-end lime-ash outlet.Low side lime-ash entrance is higher than 1cm to 3cm bottom ash-pan, and high-end lime-ash outlet is higher than ash-pan top 20cm to 30cm.
In order to realize Ash water function, ash-pan is with dynamical system, ash-pan can be rotated relative to refuse pyrolysis gasification furnace, lime-ash is made to be fed into low side lime-ash entrance through the broken pusher of crushing cutter, rotation lime-ash along with ash-pan is transported to the outlet of high-end lime-ash gradually, and then is transferred out refuse pyrolysis gasification furnace.
In order to reduce refuse pyrolysis gasification furnace spiral pushing off the slag delivery board and refuse pyrolysis gasification furnace rubs, between plate and ash-pan, leaving certain space (1cm to 3cm), preventing both collisions.
In order to realize the adjustment of lime-ash rate of discharge, ash-pan carries out the adjustment of ash-pan velocity of rotation with adjustable power set.
Be further described below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, broken conveying blade 3, comprises cutter hub front end 9 (cutter hub bottom 7, cutter hub top 8) and cutter hub rear end 6.Broken conveying blade 3 is welded in ash-pan projection 4.Cutter hub bottom 7 is lowered gradually to cutter hub top 8 height of projection, and cutter hub front end 9 reduces gradually to cutter hub rear end 6 height of projection.The quantity optimization of the blade of broken conveying blade is 4, raises into symmetrical spiral distribution along ash-pan.Each protruding 10cm in cutter hub bottom 7 is 0cm to cutter hub upper lobes, the protruding 0cm to cutter hub rear end.As shown in Figure 3, the spiral pushing off the slag delivery board 5 of refuse pyrolysis gasification furnace welds mutually with the body of heater of refuse pyrolysis gasification furnace 1 (in Fig. 3 shown in symbol 15 is spiral pushing off the slag delivery board and body of heater weld), to rise to be positioned at high-end lime-ash outlet 12 from the lime-ash entrance 13 being positioned at low side with 10 ° of baffle plate lift angle uniform spiral.Lime-ash entrance 13 is apart from the bottom 1cm of ash-pan 2, and lime-ash outlet 13 is higher than ash-pan 2 top edge 30cm.Workplace is provided with apart from being 1cm between the edge of spiral pushing off the slag delivery board 5 and ash-pan 2.
In the present embodiment, ash-pan 2 by adjustable speed motor 11 with 5 circle/minute speed at the uniform velocity rotate, ash-pan projection 4 is driven at the uniform velocity to rotate, refuse pyrolysis gasification furnace 1 maintains static, be fixed on broken conveying blade in ash-pan projection 43 and refuse pyrolysis gasify relatively rotating of furnace wall, the lime-ash be clipped in the middle fallen to the path 10 that drops from lime-ash and carries out fragmentation, more less by the distance between the furnace wall of ash-pan projection 4 bottoms and broken conveying blade, the present embodiment is 20cm, thus bulk lime-ash is broken gradually.The broken conveying blade 3 of rotation along with ash-pan promotes lime-ash and travels forward, and gradually lime-ash is discharged refuse pyrolysis gasification furnace by capstan winch 14 of slagging tap through the spiral pushing off the slag delivery board 5 be welded on refuse pyrolysis gasification furnace 1.Because broken conveying blade 3 and refuse pyrolysis gasify diminishing of distance between furnace wall, lime-ash is extruded and broken, simultaneously due to the continuous distributed of 4 blades, makes the fragmentation of lime-ash and the better effects if of conveying, and the present embodiment can be broken and export lime-ash 100kg/min.Can better broken lime-ash improve the conveying capacity (150kg/min) of lime-ash when rotating speed higher (7 circle/minute).
