Description

Vapourizing furnace duplex roller ash discharging gear

Technical field

The utility model relates to a kind of vapourizing furnace duplex roller ash discharging gear that is applied in biomass gasifying furnace or the mineral substance vapourizing furnace.

Background technology

Utilize stalk to expect that in former (combustion) bottom that afterburnt drops to furnace shell by fire bars is used as remnant and cleans out burner hearth as the biomass gasifying furnace of former (combustion) material or mineral substance vapourizing furnace as former (combustion) material or mineral substance.Before the utility model, go out clearly or draw out these burnout substances (combustion ash) and use very simple tools (as ash drawing device), also can reach certain effect in general, but can not thoroughly remove these remnants, can result in blockage for a long time, make whole firing system unimaginable problem occur.

Summary of the invention

The purpose of this utility model be to provide a kind of simple to operation, be easy to the vapourizing furnace duplex roller ash discharging gear safeguarding and the remnant in the burner hearth of furnace shell lower end (dust, slag particle etc.) thoroughly can be removed.

For achieving the above object, the technical solution adopted in the utility model is: described a kind of vapourizing furnace duplex roller ash discharging gear comprises first propellers and second propellers, first follow-up pulley and second follow-up pulley, motion-work wheel and fire door.First propellers and second propellers are installed in the furnace shell inner chamber near the base plate of furnace shell.Be furnished with first flight on the surface of first propellers, the surface of second propellers is furnished with second flight.Two of first propellers is installed in the hole of furnace shell outer wall through rotating shaft, and in the rotating shaft of one of first propellers first follow-up pulley is housed.Two of second propellers is installed in the hole of furnace shell outer wall through passing axle, and on the roll shaft of one of second propellers second follow-up pulley is housed.The motion-work wheel position is between first follow-up pulley and second follow-up pulley, and the external tooth on the motion-work wheel meshes each other with the external tooth on first follow-up pulley and second follow-up pulley respectively.Rotating shaft on the motion-work wheel is assemblied in through bearing on the wall of furnace shell, shakes on the motion-work wheel and revolves handle.Symmetrical with second follow-up pulley, on the other side wall of furnace shell, have ash output hole, on the outer wall of furnace shell, fire door is installed near ash output hole, in the lower end side of ash output hole ashpit is arranged.

Adopt a kind of vapourizing furnace duplex roller ash discharging gear that as above technical scheme provides compared with prior art, technique effect is:

1. easy to operate, deashing rate height;

2. long service life, maintenance cost is low, reduces labour intensity.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

As shown in Figure 1, described a kind of vapourizing furnace duplex roller ash discharging gear comprises first propellers 1 and second propellers 2, first follow-up pulley 3 and second follow-up pulley 6, motion-work wheel 4, ashpit 7 and fire door 9.Inner chamber at square (rectangle or square) furnace shell 8 is equipped with first propellers 1 and second propellers 2 side by side near base plate, is furnished with the first flight 1A on the surface of first propellers 1, be furnished with the second flight 2A on the surface of second propellers 2, the allocation method of the first flight 1A and the second flight 2A or installing structure form want to guarantee that the dust of furnace shell 8 inner chamber bottoms or residue can carry towards ash output hole direction (as right).Two of first propellers 1 is installed in the hole of furnace shell 8 outer walls through rotating shaft, and the outer wall by furnace shell 8 is equipped with first follow-up pulley 3 in the rotating shaft of first 1 one of the propellers, two of second propellers 2 is installed in the hole of furnace shell 8 outer walls equally through rotating shaft, second follow-up pulley 6 is housed on the roll shaft that second propellers are 2 one, between first follow-up pulley 3 and second follow-up pulley 6 motion-work wheel 4 is housed, the external tooth on the motion-work wheel 4 meshes each other with the external tooth on first follow-up pulley 3 and second follow-up pulley 6 respectively.Rotating shaft on the motion-work wheel 4 is assemblied on the wall of furnace shell 8 through bearing 5.Be equipped with on the motion-work wheel 4 to shake and revolve 4A, rotation is shaken to revolve 4A is driven motion-work wheel 4 directed rotations, rotate as the clockwise direction of motion-work wheel 4 and can drive first follow-up pulley 3 simultaneously and second follow-up pulley, 6 counter-clockwise direction are rotated, drive first propellers 1 simultaneously and second propellers 2 rotate and rotate first follow-up pulley 3 and second follow-up pulley 6 time.Flight 1A on first propellers 1 and

second propellers

2 and 2A action are with the end conveyings (as shown in Figure 2) from left to right such as dust of furnace shell 8 inwall bottoms.Have ash output hole 10 on the wall of furnace shell 8 right-hand members, the lower end of ash output hole 10 is facing to ashpit 7.At outer wall fire door 9 is installed, when not using first propellers 1 and second propellers 2, puts down fire door 9 and close tight, can not allow the dusts in the furnace shell 8 run out of near the furnace shell 8 of ash output hole 7; And when needing ash discharge, open fire door 9, hand-turning (or electrical equipment drive) is shaken to revolve 4A is driven motion-work wheel 4 and first follow-

up pulley

3 and 6 actions of second follow-up pulley, thereby makes first propellers 1 and second helix wheel, 2 synchronization actions, and dust is discharged.

The external diameter of described first follow-up pulley 3 and second follow-up pulley 6 can equate that the diameter optimal selection that makes motion-work wheel 4 simultaneously is greater than the diameter of first follow-up pulley 3 and the diameter of second follow-up pulley 6.
